Description

Technical Field

[0001] The present application generally relates to the field of electrical connectors, and more particularly to an electrical connector and a connector assembly comprising the electrical connector. Background Art

[0002] Electrical connectors are used in many electronic systems, such as communication systems, data storage systems, and data transmission systems. It is often easier and more cost-effective to manufacture electronic systems into separate electronic subassemblies such as printed circuit boards (PCBs) that can be connected together by electrical connectors.

[0003] In some cases, the PCBs to be connected can each have an electrical connector mounted thereon. The electrical connectors on the two PCBs can be directly matched to interconnect the two PCBs. In other partial cases, the PCBs can be indirectly connected by cables, or different positions on the same PCB can be connected by cables. Nevertheless, electrical connectors can still be used to establish such connections. For example, the cable can be terminated with a plug-type electrical connector at one or both ends. The PCB can be equipped with a socket-type electrical connector. The plug-type electrical connector can be inserted into the socket-type electrical connector to connect the cable to the PCB. A similar arrangement can be used at the other end of the cable to connect the cable to another PCB so that signals and / or power can be transmitted between the PCBs through the cable.

[0004] Cable components such as flexible printed circuits (FPC) and flexible flat cables (FFC) can be used to transmit signals and / or power between different PCBs or components on the same PCB. FPC / FFC connectors are usually used to connect cable components to PCBs.

[0005] FPC / FFC connectors are usually designed and manufactured to specific specifications to cooperate with cable components and PCBs and meet signal and / or power transmission requirements. Designing FPC / FFC connectors to meet specific application requirements brings many challenges. FPC / FFC connectors must have various characteristics that meet the mechanical and electrical requirements of electronic systems. Utility Model Content

[0115] Electrical connectors are used in many electronic systems. Electrical connectors can be connected together to form connector assemblies. Electrical connectors and connector assemblies must have properties that meet the mechanical and electrical requirements of electronic systems. As an example, electrical connectors and connector assemblies need to have sufficiently high safety and reliability. For example, electrical connectors need to have sufficiently high dielectric withstanding voltage performance. As another example, it is desired that electrical connectors and connector assemblies have a smaller footprint in electronic systems. As yet another example, it is desired that electrical connectors have good hot plug capabilities. As yet another example, it is desired that connector assemblies allow for convenient assembly and / or disassembly in space-constrained environments.

[0116] The inventors have recognized and appreciated a design technique for an electrical connector having characteristics that meet the mechanical and electrical requirements of an electronic system. This technique can achieve an electrical connector and connector assembly that is compact, safe, reliable, and easier to assemble and disassemble while meeting the mechanical and electrical requirements specified by specifications such as USCAR. This technique can be particularly advantageous in a line-to-board connection system.

[0117] The plug connector may include an insulating housing, a plurality of wiring members and a latch member. Each wiring member includes a connection end having a plurality of conductive contacts. The connection ends of the plurality of wiring members are arranged in the insulating housing. The latch member is mounted to the insulating housing and is configured to hold the connection ends of the plurality of wiring members in the insulating housing. With this configuration, the connection ends of the plurality of wiring members can be directly disposed in the insulating housing for establishing electrical connections with mating electrical components (e.g., socket connectors). Compared to conventional electrical connectors that utilize crimped cables to connect wiring, this configuration can simplify the structure of the plug connector and reduce its manufacturing cost. With the aid of the latch member, the connection ends of the plurality of wiring members can be reliably held in the insulating housing. Holding a plurality of wiring members by a single latch member can simplify the structure and assembly process of the plug connector.

[0118] The latch member can be mounted to the insulating housing and can be selectively placed in a pre-locking position and a locking position. This configuration enables the plug connector to meet the requirements of specifications such as USCAR. Since the latch member is pre-locked in place before the plurality of wiring members are arranged in the insulating housing, the latch member can be prevented from being lost during the arrangement of the plurality of wiring members, and the assembly efficiency of the plug connector can be improved.

[0119] The conductive contacts of the plurality of wiring members can be surrounded and protected by the receiving portion of the insulating housing to prevent being touched by the user's fingers or tools, thereby preventing the user from getting an electric shock or avoiding a short circuit. This configuration can improve the safety and reliability of the plug connector. The plurality of wiring members can include a flexible flat cable (FFC), a flexible printed circuit (FPC), or a combination thereof.

[0120] The socket connector may include an insulating housing and a plurality of conductive terminals disposed in the insulating housing. The insulating housing may include a base and a tongue extending from the base along a transverse direction. The tongue may include a first surface and a second surface opposite to each other in a vertical direction perpendicular to the transverse direction. Each conductive terminal includes a mating end having a mating contact portion, a mounting end opposite to the mating end, and an intermediate portion connecting the mating end and the mounting end. The plurality of conductive terminals may include a plurality of first conductive terminals and a plurality of second conductive terminals. The plurality of first conductive terminals are arranged in a first row along a longitudinal direction perpendicular to the transverse direction and the vertical direction, and the mating ends of the plurality of first conductive terminals extend into the tongue so that their mating contact portions protrude from the first surface. The plurality of second conductive terminals are arranged in a second row along the longitudinal direction, and the mating ends of the plurality of second conductive terminals extend into the tongue so that their mating contact portions protrude from the second surface. The mating ends of the plurality of first conductive terminals and the mating ends of the plurality of second conductive terminals may be staggered from each other in the vertical direction. This arrangement enables the first row and the second row to be arranged with a smaller spacing in the vertical direction while still ensuring sufficient spacing between the mating ends of the first conductive terminals and the mating ends of the second conductive terminals. This arrangement can reduce the size (ie, height) of the socket connector in the vertical direction Z. This is conducive to miniaturization of the socket connector and can reduce the space occupied by the socket connector in the electronic system.

[0121] The base of the insulating housing of the socket connector may include a third surface and a fourth surface at a side opposite to the tongue. The third surface and the fourth surface are both perpendicular to the transverse direction and face the same direction. The fourth surface is farther from the tongue than the third surface in the transverse direction. The mounting ends of the plurality of first conductive terminals extend from the third surface of the base along the transverse direction, and the mounting ends of the plurality of second conductive terminals extend from the fourth surface of the base along the transverse direction. Through this configuration, the creepage distance between the mounting ends of the plurality of first conductive terminals and the mounting ends of the plurality of second conductive terminals can be increased, thereby allowing the plurality of first conductive terminals and the plurality of second conductive terminals to be arranged at a closer spacing, and improving the insulation withstand voltage performance of the socket connector. This makes it possible to reduce the size of the socket connector in the transverse direction and / or the longitudinal direction. This is conducive to the miniaturization of the socket connector and can reduce the occupied space of the socket connector in the electronic system.

[0122] The mating end of the conductive terminal of the socket connector may have a double beam and double contacts configuration. This configuration can improve the electrical connection reliability of the socket connector and effectively prevent instantaneous disconnection. In addition, this configuration can improve the current carrying capacity of the conductive terminal, so that the socket connector can meet the needs of transmitting large currents. In addition, this configuration can increase the contact density of the socket connector, which is conducive to the miniaturization of the socket connector.

[0123] The plug connector and the socket connector may mate with each other to form a connector assembly. A connector position assurance (CPA) device may reliably lock the plug connector and the socket connector together. In addition, the plug connector and the socket connector may have guiding features that cooperate with each other. Such guiding features may prevent the plug connector from being inserted into the socket connector in a skewed orientation, thereby providing protection for the mating conductive structures of the plug connector and the socket connector, and may improve the hot plugging capability of the connector assembly.

[0124] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. It should be understood that these embodiments are not intended to limit the present application in any way. In addition, the features in the embodiments of the present application may be combined with each other in the absence of conflict.

[0125] Electronic Systems

[0126] Figures 1A to 3B An electronic system 1 according to some embodiments of the present application is schematically shown, which includes an electrical connector 10 , an electrical connector 20 , and a circuit board 30 .

[0127] For the sake of clarity and simplicity, Figures 1A to 16E , a transverse direction XX, a longitudinal direction YY and a vertical direction ZZ are defined in the figure. The transverse direction XX, the longitudinal direction YY and the vertical direction ZZ are perpendicular to each other. The transverse direction XX generally refers to the width direction of the electrical connector 10 and the electrical connector 20. The longitudinal direction YY generally refers to the length direction of the electrical connector 10 and the electrical connector 20. The vertical direction ZZ generally refers to the height direction of the electrical connector 10 and the electrical connector 20.

[0128] like Figures 1A to 1C As shown, the electronic system 1 includes an electrical connector 10 , an electrical connector 20 and a circuit board 30 .

[0129] The circuit board 30 may also be referred to as a “printed circuit board” or “PCB.” The circuit board 30 may be a main board, such as a main board of a battery management system (BMS).

[0130] The electrical connector 20 may be an on-board connector that is mounted and connected to the circuit board 30. Specifically, the electrical connector 20 may be mechanically fixed to the circuit board 30 and electrically connected to a conductive structure (e.g., a conductive pad or a conductive through hole) of the circuit board 30. The electrical connector 20 may provide an electrical interface that electrically connects the electrical connector 10 to the circuit board 30.

[0131] The electrical connector 10 may be configured to electrically connect an electrical component to the electrical connector 20 and the circuit board 30. The electrical component may be, for example, a cell sensing circuit (CSC) configured to monitor the status (eg, voltage and temperature) of a battery cell.

[0132] The electrical connector 10 and the electrical connector 20 can establish an electrical connection between the circuit board 30 and the electrical component to achieve signal and / or power transmission. Exemplarily, the status data of the battery cell collected by the CSC can be transmitted to the data acquisition module of the BMS through the electrical connector 10 and the electrical connector 20. The electrical connector 10 and the electrical connector 20 can constitute a connector assembly for signal and / or power transmission. It should be understood that the use of the electronic system 1 and the connector assembly according to the present application is not limited to this. In other embodiments, the electrical connector 10 and the electrical connector 20 can be used for an on-board charger (OBC), a micro control unit (MCU), etc.

[0133] like Figures 1A to 3B As shown, the electrical connector 20 is disposed on a surface 31 of a circuit board 30 and is connected to a conductive structure 32 (which is located on a surface 31 of a circuit board 30) of the circuit board 30. Figure 1C As will be described in detail below, a portion of the electrical connector 10 is inserted into the housing of the electrical connector 20 so that the conductive structure of the electrical connector 10 is matched with the matching conductive structure of the electrical connector 20. The electrical connector 10 may also be referred to as a "first electrical connector" or a "plug connector", and the electrical connector 20 may also be referred to as a "second electrical connector" or a "socket connector".

[0134] Plug connector

[0135] FIG. 4A to FIG. 8B The configuration of the electrical connector 10 is shown in detail. Figure 4A and Figure 4B As shown, the electrical connector 10 may include an insulating housing 100 , a plurality of cable members 200 , a latch member 300 and a latch member 400 .

[0136] The wiring member 200 may be a flexible electrical connection member having a flat-shaped connection end. The wiring member 200 may also be referred to as a "wiring". Exemplarily, the wiring member 200 may be electrically connected to an electrical component such as a CSS described above, or the wiring member 200 itself may be a part of an electrical component such as a CSS described above. The wiring member 200 may be, for example, a flexible printed circuit (FPC) or a flexible flat cable (FFC). The plurality of wiring members 200 of the electrical connector 10 may include an FFC, an FPC, or a combination thereof.

[0137] A plurality of wiring members 200 are Figure 4A and Figure 4B 200A and the second wiring member 200B. The first wiring member 200A may also be referred to as an "upper wiring member", and the second wiring member 200B may also be referred to as a "lower wiring member". The configuration of the electrical connector 10 is described in detail below in conjunction with an example in which the electrical connector 10 includes two wiring members. It should be understood that the present application is not limited thereto, and the electrical connector 10 may include more than two (e.g., three, four, five, etc.) wiring members.

[0138] Figure 4B A first side (ie, back side) of the first wiring member 200A is shown, and Figure 4E The second side (ie, the front side) of the first wiring member 200A opposite to the first side is shown. Figure 4B and Figure 4E As shown, the first wiring member 200A includes a main body 201 and a connecting end 202 .

[0139] The connecting end 202 may have a flat shape. The connecting end 202 may include a first surface 202a and a second surface 202b opposite to each other in the vertical direction ZZ. A plurality of conductive contacts 203 may be exposed at the first surface 202a of the connecting end 202. The conductive contact 203 may also be referred to as a "conductive contact strip" or a "gold finger". The conductive contact 203 may be formed of a conductive material. The conductive material suitable for manufacturing the conductive contact 203 may be a metal material, such as a copper alloy. The main body 201 may extend from the connecting end 202 to the other end (not shown) of the first wiring member 200A, and provide an electrical connection between the connecting end 202 and the other end, thereby realizing signal and / or power transmission. The main body 201 may be flexible, for example, to be suitable for being bent. The connecting end 202 may be hardened to be suitable for being inserted into the insulating housing 100 and establishing an electrical connection with a mating electrical component (e.g., an electrical connector 20).

[0140] The structure of the second wiring member 200B is substantially the same as that of the first wiring member 200A. For simplicity, the same reference numerals are used in the drawings to indicate the same or similar structures of the second wiring member 200B and the first wiring member 200A, and the details of these structures are not repeated.

[0141] like Figure 4A , Figure 4C and Figure 4D As shown, the connection end 202 of the first wiring member 200A and the connection end 202 of the second wiring member 200B are disposed in the insulating housing 100. The latch member 300 is mounted to the insulating housing 100 and may be configured to hold and lock the connection end 202 of the first wiring member 200A and the connection end 202 of the second wiring member 200B in the insulating housing 100. The latch member 300 may also be referred to as a "first latch member" or an "FPC / FFC position assurance (FPA) device".

[0142] By this configuration, the connection end 202 of the first wiring member 200A and the connection end 202 of the second wiring member 200B can be directly disposed in the insulating housing 100 for establishing electrical connection with a mating electrical component. Compared with a conventional electrical connector that uses crimped cables to connect wiring, this configuration can simplify the structure of the electrical connector 10 and reduce its manufacturing cost. With the aid of the latch member 300, the connection end 202 of the first wiring member 200A and the connection end 202 of the second wiring member 200B can be reliably retained in the insulating housing 100. Retaining multiple wiring members by a single latch member 300 can simplify the structure and assembly process of the electrical connector 10.

[0143] The insulating housing 100 and the latch member 300 may be made of insulating materials. Examples of insulating materials include, but are not limited to, plastic, nylon, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO), or polypropylene (PP).

[0144] like Figure 4B , Figure 4C , Fig. 6A , Figure 6B , Fig. 8A and Figure 8B As shown, the insulating housing 100 includes a base 110, and two first channels 111 each extending from a first surface 110a of the base 110 along a transverse direction XX through the base 110. The two first channels 111 are spaced apart from each other in a vertical direction ZZ perpendicular to the transverse direction XX. For example, the two first channels 111 may be spaced apart from each other in the vertical direction ZZ by a portion of the base 110.

[0145] like Figure 4A and Figure 4E As shown, the connection end 202 of the first wiring member 200A may include a first section 210 and a second section 220. The first section 210 of the connection end 202 extends from the body 201 along the transverse direction XX, and the second section 220 extends from the first section 210 along the transverse direction XX away from the body 201. In other words, the first section 210 extends between the second section 220 and the body 201, and connects the second section 220 and the body 201. The first wiring member 200A may terminate at the second section 220. A plurality of conductive contacts 203 are located on the second section 220. The structure of the connection end 202 of the second wiring member 200B is substantially the same as that of the connection end 202 of the first wiring member 200A. For the sake of brevity, the details of these identical parts will not be repeated.

[0146] like FIG. 6A to FIG. 8B As shown, the connection end 202 of each of the first wiring member 200A and the second wiring member 200B can be inserted into the insulating housing 100 through a corresponding one of the two first channels 111 from the first face 110a of the base 110. When the first wiring member 200A and the second wiring member 200B are disposed in place in the insulating housing 100, the first section 210 of the connection end 202 of each of the first wiring member 200A and the second wiring member 200B is disposed in a corresponding one of the two first channels 111. The connection end 202 of the first wiring member 200A is disposed in the upper first channel 111, and the connection end 202 of the second wiring member 200B is disposed in the lower first channel 111. The connection ends 202 of the first wiring member 200A and the second wiring member 200B are spaced apart from each other in the vertical direction ZZ. Through this configuration, the base 110 can limit the movement of the first section 210 of the connecting end 202 of the first wiring assembly 200A and the second wiring assembly 200B relative to the insulating housing 100 in the longitudinal direction YY and the vertical direction ZZ, thereby maintaining the connecting end 202 of the first wiring assembly 200A and the second wiring assembly 200B in the longitudinal direction YY and the vertical direction ZZ.

[0147] The first section 210 of each of the first wiring member 200A and the second wiring member 200B has a side edge. Figure 4B and Figure 4E , the first section 210 of the connecting end 202 of the first wiring member 200A includes a first side edge 211 and a second side edge 212 opposite to each other in the longitudinal direction YY. Similarly, the first section 210 of the connecting end 202 of the second wiring member 200B may also include a first side edge 211 and a second side edge 212 opposite to each other in the longitudinal direction YY.

[0148] In some embodiments, Fig. 6A and Figure 6B As shown, the latch member 300 is mounted to the base 110 and is configured to be selectively placed in a pre-locking position ( Fig. 6A ) and locked position ( Figure 6B That is, the latch member 300 can be selectively locked in the pre-locking position / state ( Fig. 6A ) and locked position / state( Figure 6B ) and still remain mounted to the base 110.

[0149] In such Fig. 6A In the pre-locked position shown, the latch member 300 does not engage with the side edges (i.e., the first side edge 211 and / or the second side edge 212) of the first segment 210 of the first wiring member 200A and the second wiring member 200B to allow the first segment 210 to move along the lateral direction XX through the first channel 111. That is, in the pre-locked position, the latch member 300 is mounted to the base 110 and allows the connection end 202 of each of the first wiring member 200A and the second wiring member 200B to be inserted into the insulating housing 100 from the first face 110a of the base 110 through the corresponding first channel 111.

[0150] In such Figure 6B In the locking position shown, the latch member 300 engages with the side edges (i.e., the first side edge 211 and / or the second side edge 212) of the first segment 210 of the first wiring member 200A and the second wiring member 200B to retain the first segment 210 in the first channel 111. That is, in the locking position, the latch member 300 can block the first segment 210 from moving along the lateral direction XX in the first channel 111, thereby retaining the first segment 210 in the first channel 111. In this way, the latch member 300 is able to retain the connection ends 202 of the first wiring member 200A and the second wiring member 200B in the insulating housing 100.

[0151] When placed in the pre-locked position, the latch member 300 can be mounted to the insulating housing 100 and allow the connection ends 202 of the first and second wiring members 200A and 200B to be inserted into the insulating housing 100. When placed in the locked position, the latch member 300 holds the connection ends 202 of the first and second wiring members 200A and 200B in the insulating housing 100. This configuration can allow the latch member 300 to be mounted to the insulating housing 100 (i.e., the latch member 300 is pre-locked in place) before the first and second wiring members 200A and 200B are inserted into the insulating housing 100, and the first and second wiring members 200A and 200B are locked in place using the latch member 300 pre-installed to the insulating housing 100 after the first and second wiring members 200A and 200B are inserted into the insulating housing 100. This configuration can enable the electrical connector 10 to meet the requirements of specifications such as USCAR. Since the latch member 300 is pre-locked in place before being inserted into the first and second wire routing members 200A and 200B, it is possible to avoid the latch member 300 from being lost during installation of the first and second wire routing members 200A and 200B, and the assembly efficiency of the electrical connector 10 can be improved.

[0152] For each of the first wiring member 200A and the second wiring member 200B, the side edge of the first section 210 is disposed in the end section of the corresponding first channel 111. Fig. 6A As shown, the first side edge 211 of the first section 210 is disposed in the first end section 111a of the corresponding first channel 111, and the second side edge 212 is disposed in the second end section 111b of the first channel 111. The first end section 111a and the second end section 111b are respectively located at opposite ends of the first channel 111 in the longitudinal direction YY.

[0153] In some embodiments, FIG. 6A to FIG. 6B As shown, the insulating housing 100 may include two second channels 112. Each second channel 112 extends from the outside of the base 110 (in the figure, the second surface or bottom surface 110b of the base 110) along the vertical direction ZZ into the base 110 and passes through the corresponding end sections of the plurality of first channels 111 (i.e., the corresponding end sections of the first end section 111a and the second end section 111b). FIG. 5A to FIG. 6B As shown, the latch member 300 may include two first arms 310. Each first arm 310 includes a first body 311 extending along a vertical direction ZZ, and a first groove 312 extending through the first body 311 along a transverse direction XX. FIG. 6A to FIG. 6BAs shown, each of the two first arms 310 is inserted into a corresponding one of the two second channels 112 , and is configured to be movable along a vertical direction ZZ in the corresponding one of the second channels 112 .

[0154] When the latch member 300 is placed in the pre-locking position, the first groove 312 of each first arm 310 is aligned with the end section of a corresponding first channel 111 in the transverse direction XX to allow the side edge of the corresponding first section 210 to move through the end section and the first groove 312 along the transverse direction XX. Fig. 6A and Figure 6C As shown, when the latch member 300 is placed in the pre-locking position, the first groove 312 of one of the two first arms 310 is aligned with the first end section 111a of the lower first channel 111 in the transverse direction XX, and the first groove 312 of the other of the two first arms 310 is aligned with the second end section 111b of the lower first channel 111 in the transverse direction XX. This allows the first side edge 211 and the second side edge 212 of the first section 210 of the second wiring member 200B to move through the corresponding end sections and the first groove 312 respectively along the transverse direction XX, thereby allowing the connection end 202 of the second wiring member 200B to pass through the first channel 111 along the transverse direction XX. This enables the connection end 202 of the second wiring member 200B to be inserted into and removed from the insulating housing 100 along the transverse direction XX.

[0155] In addition, if Fig. 6A and Figure 6C As shown, when the latch member 300 is placed in the pre-locking position, the tops of the first bodies 311 of the two first arms 310 do not extend in the vertical direction ZZ into the corresponding end sections of the first channel 111 for inserting the first wiring member 200A, that is, the tops of the first bodies 311 of the two first arms 310 are located below the corresponding end sections of the first channel 111. This allows the first side edge 211 and the second side edge 212 of the first section 210 of the first wiring member 200A to move through the corresponding end sections along the transverse direction XX, thereby allowing the connection end 202 of the first wiring member 200A to pass through the first channel 111 along the transverse direction XX. This enables the connection end 202 of the first wiring member 200A to be inserted into and removed from the insulating housing 100 along the transverse direction XX. It should be understood that the present application is not limited thereto. In some other embodiments, the first body 311 of the first arm 310 may include an additional first groove 312 configured to align with a corresponding end section of the first channel 111 for inserting the upper portion of the first wiring member 200A when the latch member 300 is placed in the pre-locking position.

[0156] That is, each first arm 310 may include at least one first groove 312 extending through the first body 311 along the transverse direction XX. When the latch member 300 is placed in the pre-locking position, each of the at least one first groove 312 of each first arm 310 may be aligned with an end section of a corresponding one of the plurality of first channels 111 in the transverse direction XX to allow a side edge of the corresponding first segment 210 to move through the end section and the first groove 312 along the transverse direction XX.

[0157] In some embodiments, the first segment 210 of each of the first wiring member 200A and the second wiring member 200B may include a notch recessed from the side edge into the first segment 210 along the longitudinal direction YY. Figure 4E As shown, the first segment 210 of the first wiring member 200A may include a first notch 213 recessed into the first segment 210 along the longitudinal direction YY from the first side edge 211 and a second notch 214 recessed into the first segment 210 along the longitudinal direction YY from the second side edge 212. The structure of the first segment 210 of the second wiring member 200B is substantially the same as that of the first segment 210 of the first wiring member 200A, and may include a first notch 213 and a second notch 214. For the sake of brevity, the details of these identical parts are not repeated.

[0158] When the first and second wiring members 200A and 200B are disposed in place in the insulating housing 100 , the corresponding notches of the first sections 210 of the first and second wiring members 200A and 200B are aligned with each other in the vertical direction ZZ and with a corresponding one of the two second channels 112 . Specifically, when the first wiring member 200A and the second wiring member 200B are set in place in the insulating housing 100, the first notches 213 (which are at the first side edge 211) of the first sections 210 of the first wiring member 200A and the second wiring member 200B are aligned with each other in the vertical direction ZZ and aligned with one of the two second channels 112, and the second notches 214 (which are at the second side edge 212) of the first sections 210 of the first wiring member 200A and the second wiring member 200B are aligned with each other in the vertical direction ZZ and aligned with the other of the two second channels 112.

[0159] When the latch member 300 is placed in the locking position, the first groove 312 of the first arm 310 of the latch member 300 is moved to be offset from the end sections of the plurality of first channels 111 in the transverse direction XX, and the first body 311 of the first arm 310 is moved into and engaged with the notch of the first section 210 of the first wiring member 200A and the second wiring member 200B to retain the first section 210 in the first channel 111. Specifically, as Figure 6B and Fig.6D As shown, when the latch member 300 is placed in the locking position, the first groove 312 of one of the two first arms 310 is moved to be offset with the first end sections 111a of the two first channels 111 in the transverse direction XX, and the first groove 312 of the other of the two first arms 310 is moved to be offset with the second end sections 111b of the two first channels 111 in the transverse direction XX. The first body 311 of one of the two first arms 310 is moved into the first notch 213 of the first section 210 of the first wiring member 200A and the first notch 213 of the first section 210 of the second wiring member 200B, and engages with the two first notches 213. Specifically, the lower section of the first body 311 is received in the first notch 213 of the second wiring member 200B, and the upper section of the first body 311 is received in the first notch 213 of the first wiring member 200A. The first body 311 of the other of the two first arms 310 is moved into the second notch 214 of the first section 210 of the first wiring member 200A and the second notch 214 of the first section 210 of the second wiring member 200B, and engages with the two second notches 214. The lower section of the first body 311 is received in the second notch 214 of the second wiring member 200B, and the upper section of the first body 311 is received in the second notch 214 of the first wiring member 200A. In this way, the first section 210 of the first wiring member 200A and the first section 210 of the second wiring member 200B are respectively reliably held in the corresponding first channels 111, so that the connection ends 202 of the first wiring member 200A and the second wiring member 200B are held in the insulating housing 100.

[0160] like FIG. 5A to FIG. 5CAs shown, the latch member 300 may include a plate body 330. The plate body 330 may also be referred to as a "pressing plate". Each of the two first arms 310 extends from the plate body 330 along the vertical direction ZZ. The latch member 300 may also include two second arms 320. The two second arms 320 may be configured to attach the latch member 300 to the base 110 of the insulating housing 100. Each second arm 320 extends from the plate body 330 along the vertical direction ZZ and includes a snap portion 321. The second arm 320 may be an elastic arm. The snap portion 321 may be in the shape of a barb. The snap portions 321 of the two second arms 320 are opposite to each other in the longitudinal direction YY.

[0161] like Figure 4B , Figure 6C and Fig.6D As shown, the base 110 may include two first slots 113 and two second slots 114. When the latch member 300 is mounted to the base 110, the buckle portion 321 of each of the two second arms 320 is configured to be selectively inserted into a corresponding first slot 113 and a corresponding second slot 114. Fig. 6A and Figure 6C As shown, when the buckle portion 321 of each of the two second arms 320 is locked into a corresponding first locking groove 113, the latch member 300 is placed in the pre-locking position. Figure 6B and Fig.6D As shown, when the snap-fit ​​portion 321 of each of the two second arms 320 is snapped into a corresponding second snap-fit ​​groove 114, the latch member 300 is placed in the locking position. Through this snap-fit, the latch member 300 can be reliably maintained in the pre-locking position and the locking position, and the latch member 300 can be conveniently switched between the pre-locking position and the locking position.

[0162] Exemplarily, when the latch member 300 is placed in the pre-locking position, by pressing the plate body 330 along the vertical direction ZZ, the latch member 300 can be pushed to move the two second arms 320 from the corresponding first slots 113 to the corresponding second slots 114, so as to move the latch member 300 to the locking position. When the latch member 300 is placed in the locking position, the two second arms 320 can be released from the corresponding second slots 114 and the two second arms 320 can be inserted into the corresponding first slots 113, so as to place the latch member 300 in the pre-locking position. In addition, the latch member 300 can be removed from the base 110 by releasing the two second arms 320 from the corresponding first slots 113 or the corresponding second slots 114.

[0163] In some embodiments, Figure 5CAs shown, the two first arms 310 of the latch member 300 can extend from the first surface 331 of the plate body 330 along the vertical direction ZZ, and the two first arms 310 can be aligned with each other in the longitudinal direction YY to define a first center line L1. The two second arms 320 can extend from the first surface along the vertical direction ZZ, and the two second arms 320 can be aligned with each other in the longitudinal direction YY to define a second center line L2. In one of these embodiments, the first center line L1 and the second center line L2 do not coincide. This configuration can provide a foolproof function to prevent the latch member 300 from being installed to the base 110 in an incorrect orientation.

[0164] like FIG. 5A to FIG. 5C As shown, the plate body 330 of the latch member 300 includes a first end 330a and a second end 330b opposite to each other in the longitudinal direction YY. The two second arms 320 extend from the first surface 331 of the plate body 330 along the vertical direction ZZ at the first end 330a and the second end 330b, respectively. The two first arms 310 may extend from the first surface 331 of the plate body 330 along the vertical direction ZZ between the two second arms 320.

[0165] like Figure 4B , Fig. 6A and Figure 6B As shown, the base 110 includes a first end surface 110c and a second end surface 110d opposite to each other in the longitudinal direction YY, a second groove 115 recessed into the base 110 from the first end surface 110c along the longitudinal direction YY, and a third groove 116 recessed into the base 110 from the second end surface 110d along the longitudinal direction YY. The aforementioned first clamping groove 113 and second clamping groove 114 are formed at the bottom of the second groove 115 and the bottom of the third groove 116, respectively. When the latch member 300 is mounted to the base 110, the two second arms 320 of the latch member 300 are respectively received in the second groove 115 and the third groove 116. In this way, the two second arms 320 of the latch member 300 can be protected by the base 110 so as not to be loosened from the base 110 due to accidental touch. Through this configuration, the reliability of the mounting of the latch member 300 to the base 110 can be improved, and the mounting, adjustment and removal of the latch member 300 can be facilitated.

[0166] like Figure 4A and Figure 4BAs shown, the insulating housing 100 may include a receiving portion 150. The receiving portion 150 extends from the base 110 along the lateral direction XX and encloses a receiving space 140. The receiving space 140 is open at an end opposite to the base 110. The second section 220 of the first wiring member 200A and the second wiring member 200B is positioned in the receiving space 140. Through this configuration, the conductive contacts 203 of the first wiring member 200A and the second wiring member 200B can be protected by the receiving portion 150 to prevent being touched by the user's fingers or tools, thereby avoiding electric shock to the user or avoiding short circuits. This configuration can improve the safety and reliability of the electronic system 1 using the electrical connector 10.

[0167] Exemplarily, the leading edges of the second segments 220 of the connecting ends 202 of the first and second wiring members 200A and 200B may be respectively retracted into the accommodation space 140 by a certain distance in the transverse direction XX relative to the opening of the accommodation portion 150. For example, the distance may be greater than or equal to 1 mm.

[0168] The accommodating portion 150 of the insulating housing 100 may be formed by a plurality of walls extending from the base 110 along the transverse direction XX. The plurality of walls may include a first wall 151 and a second wall 152 that are opposite to and spaced apart from each other in the vertical direction ZZ, and a third wall 153 and a fourth wall 154 that are opposite to and spaced apart from each other in the longitudinal direction YY. The first wall 151, the second wall 152, the third wall 153, and the fourth wall 154 enclose an accommodating space 140. In addition, the accommodating portion 150 may be used as an insertion portion of the insulating housing 100 for being inserted into a housing of another electrical connector (e.g., an electrical connector 20 to be described below) that mates with the electrical connector 10.

[0169] The second section 220 of the first wiring member 200A and the second section 220 of the second wiring member 200B are adjacent to each other and spaced apart from each other in the vertical direction ZZ. The plurality of conductive contacts 203 of the first wiring member 200A (which are located on the second section 220) and the plurality of conductive contacts 203 of the second wiring member 200B (which are located on the second section 220) are opposite to each other and spaced apart in the vertical direction ZZ. That is, the second section 220 of the first wiring member 200A and the second section 220 of the second wiring member 200B define a slot therebetween, which may be elongated along the longitudinal direction YY. The plurality of conductive contacts 203 of the first wiring member 200A and the plurality of conductive contacts 203 of the second wiring member 200B are located at opposite sides of the slot in the vertical direction ZZ. As will be described in detail below, an insertion portion such as a tongue of the electrical connector 20 may be inserted between the second section 220 of the first cable member 200A and the second section 220 of the second cable member 200B, ie, into the slot.

[0170] The second section 220 of each of the first wiring member 200A and the second wiring member 200B has a side edge. Figure 4B , Figure 4E and Fig. 7A As shown, the second section 220 of the first wiring member 200A includes a first side edge 221 and a second side edge 222 opposite to each other in the longitudinal direction YY. Figure 7B As shown, similar to the first wiring member 200A, the second segment 220 of the second wiring member 200B includes a third side edge 223 and a fourth side edge 224 that are opposite to each other in the longitudinal direction YY.

[0171] In some embodiments, the second segment 220 of each of the first wiring member 200A and the second wiring member 200B may include a notch recessed from its side edge along the longitudinal direction YY into the second segment 220. The insulating housing 100 may also include a plurality of third arms extending from the base 110 along the transverse direction XX into the accommodating space 140, and each third arm may include a snap portion. When the first wiring member 200A and the second wiring member 200B are set in place in the insulating housing 100, the snap portion of each of the plurality of third arms engages with the notch of the second segment 220 of the corresponding wiring member in the first wiring member 200A and the second wiring member 200B to hold the second segment 220 in the accommodating space 140.

[0172] Specifically, if Figure 4B , Figure 4E and Fig. 7AAs shown, the second section 220 of the first wiring member 200A may include a first notch 225 recessed from the first side edge 221 along the longitudinal direction YY into the second section 220, and a second notch 226 recessed from the second side edge 222 along the longitudinal direction YY into the second section 220. Figure 7B and FIG. 8A to FIG. 8B As shown, the second section 220 of the second wiring member 200B may include a third notch 227 recessed into the second section 220 from the third side edge 223 along the longitudinal direction YY, and a fourth notch 228 recessed into the second section 220 from the fourth side edge 224 along the longitudinal direction YY.

[0173] like Fig. 8A and Figure 8B As shown, the insulating housing 100 may include a plurality of third arms 160 extending from the base 110 along the lateral direction XX into the accommodation space 140 . Fig. 8A The first and second wiring members 200A, 200B are shown being inserted into the insulating housing 100 but are not locked by the third arm 160 of the insulating housing 100 . Figure 8B The first and second wiring members 200A, 200B are shown disposed in place in the insulating housing 100 and locked by the third arm 160 .

[0174] Specifically, each third arm 160 includes a buckle portion 161. The third arm 160 may be an elastic arm. The buckle portion 161 may be in the shape of a barb. The plurality of third arms 160 may include a first group. In this embodiment, the first group includes two third arms 160. Fig. 8A Only one of the third arms 160 is shown. Fig. 8A As shown, the first set of third arms 160 extend from the base 110 along the transverse direction XX and between the second segment 220 of the first wiring member 200A and the second segment 220 of the second wiring member 200B. Each third arm 160 in the first set is configured to engage with a corresponding one of the first notch 225 and the second notch 226 of the second segment 220 of the first wiring member 200A. Fig. 7A and Figure 8B As shown, when the first wiring assembly 200A is set in place in the insulating housing 100, the snap-fit ​​portions 161 of the two third arms 160 respectively engage with the first recess 225 and the second recess 226 of the second section 220 of the first wiring assembly 200A to retain the second section 220 of the first wiring assembly 200A in the accommodating space 140.

[0175] The plurality of third arms 160 may further include a second group. In this embodiment, the second group includes two third arms 160. Fig. 8AOnly one of the third arms 160 is shown. Similar to the first group, Fig. 8A As shown, the second set of third arms 160 also extend from the base 110 along the transverse direction XX and between the second segment 220 of the first wiring member 200A and the second segment 220 of the second wiring member 200B. Each third arm 160 in the second set is configured to engage with a corresponding one of the third notch 227 and the fourth notch 228 of the second segment 220 of the second wiring member 200B. Figure 7B and Figure 8B As shown, when the second wiring assembly 200B is set in place in the insulating housing 100, the snap-fit ​​portions 161 of the two third arms 160 respectively engage with the third recess 227 and the fourth recess 228 of the second section 220 of the second wiring assembly 200B to retain the second section 220 of the second wiring assembly 200B in the accommodating space 140.

[0176] Through this configuration, the connection ends 202 of the first and second wiring members 200A and 200B can be pre-locked in the insulating housing 100 before the latching member 300 is used to lock the connection ends 202, thereby facilitating the operation of the latching member 300 to lock the connection ends 202. In addition, this configuration can reliably retain the second sections 220 of the first and second wiring members 200A and 200B in the insulating housing 100. For example, when the electrical connector 10 is mated with the electrical connector 20, this configuration can prevent the second sections 220 of the first and second wiring members 200A and 200B from shifting or tilting, thereby improving the reliability of the electrical connector 10.

[0177] like Fig. 8A and Figure 8B As best shown, each of the plurality of third arms 160 may include a third body 160a. The buckle portion 161 protrudes from the third body 160a along the vertical direction ZZ. The second wall 152 and the third body 160a of the third arm 160 in the second group clamp the side edge of the second segment 220 of the second wiring member 200B therebetween. By this configuration, the second segment 220 of the second wiring member 200B can be guided to be inserted into the accommodation space 140. In addition, the second segment 220 of the second wiring member 200B can be reliably retained in the accommodation space 140. It is conceivable that the first wall 151 and the third body 160a of the third arm 160 in the first group can clamp the side edge of the second segment 220 of the first wiring member 200A therebetween. By this configuration, the second segment 220 of the first wiring member 200A can be guided to be inserted into the accommodation space 140. Furthermore, the second section 220 of the first wiring member 200A can be reliably held in the accommodation space 140 .

[0178] In some embodiments, Fig. 7A As shown, the profile of the first side edge 221 and the profile of the second side edge 222 of the first wiring member 200A are asymmetric about the center line L3 of the second segment 220. This configuration can provide a foolproof function to prevent the first wiring member 200A from being inserted into the accommodation space 140 in a wrong orientation (in which the plurality of conductive contacts 203 of the first wiring member 200A face the first wall 151).

[0179] In some embodiments, Figure 7B As shown, the profile of the third side edge 223 and the profile of the fourth side edge 224 of the second wiring member 200B are asymmetric about the center line L4 of the second segment 220. This configuration can provide a foolproof function to prevent the second wiring member 200B from being inserted into the accommodation space 140 in a wrong orientation (in which the plurality of conductive contacts 203 of the second wiring member 200B face the second wall 152).

[0180] In some embodiments, Figure 3A As shown, the first segment 210 of the first wiring member 200A and the first segment 210 of the second wiring member 200B are parallel to each other and define a midplane PL1 therebetween. Fig. 7A As shown, the first side edge 211 and the second side edge 212 of the first segment 210 of the first wiring member 200A define a first outer contour of the first wiring member 200A. Figure 7B As shown, the first side edge 211 and the second side edge 212 of the first section 210 of the second wiring member 200B define the second outer contour of the second wiring member 200B. The first outer contour of the first wiring member 200A and the second outer contour of the second wiring member 200B are asymmetric about the midplane PL1. This configuration can provide a foolproof function to prevent the first wiring member 200A and the second wiring member 200B from being inserted into the wrong first channel 111.

[0181] like Figure 4A and Figure 4B As shown, the first wall 151 and the third wall 153 of the insulating shell 100 are connected to each other at the first corner, the first wall 151 and the fourth wall 154 are connected to each other at the second corner, the second wall 152 and the third wall 153 are connected to each other at the third corner, and the second wall 152 and the fourth wall 154 are connected to each other at the fourth corner.

[0182] In some embodiments, the receiving portion 150 of the insulating housing 100 may include a first rib 171 protruding outwardly from the first wall 151 along the vertical direction ZZ at the first corner, and a second rib 172 protruding outwardly from the first wall 151 along the vertical direction ZZ at the second corner. The first rib 171 and the second rib 172 extend along the transverse direction XX respectively. As will be described in detail below, the first rib 171 and the second rib 172 are configured to cooperate with the corresponding groove of the housing when the receiving portion 150 of the insulating housing 100 is inserted into the housing of the electrical connector 20 to guide the insertion of the insertion portion. This configuration can prevent the electrical connector 10 from being inserted into the housing of the electrical connector 20 in a skewed orientation, thereby providing protection for the matching conductive structures of the electrical connector 10 and the electrical connector 20, and can improve the hot plug capability of the electrical connector 10. Optionally or additionally, the insulating housing 100 may include ribs at the third corner and the fourth corner.

[0183] In some embodiments, Figure 4A and Figure 4D As shown, the third wall 153 of the insulating housing 100 can extend beyond the first wall 151 and the second wall 152 in the transverse direction XX to form a first protrusion 173, and the fourth wall 154 can extend beyond the first wall 151 and the second wall 152 in the transverse direction XX to form a second protrusion 174. As will be described in detail below, the first protrusion 173 and the second protrusion 174 are configured to cooperate with the corresponding recess of the housing when the receiving portion 150 of the insulating housing 100 is inserted into the housing of the electrical connector 20. This configuration can increase the size of the receiving portion 150 in the mating direction without increasing the overall width of the electrical connector 10 and the electrical connector 20. When the receiving portion 150 of the electrical connector 10 is inserted into the housing of the electrical connector 20, this configuration can guide the receiving portion 150 to be in the correct orientation and reduce its shaking amount, thereby improving the hot plugging capability of the electrical connector 10. In addition, if the receiving portion 150 of the electrical connector 10 is inserted into the housing of the electrical connector 20 in a skewed orientation, this configuration can prevent the conductive parts of the electrical connector 10 and the electrical connector 20 from contacting each other to protect the circuit from damage. This can improve the hot plug capability and reliability of the electrical connector 10.

[0184] Figure 4F is with Figure 4A A similar stereogram shows another type of electrical connector 10. Specifically, Figure 4F The electrical connector 10 shown is Figure 4A The electrical connector 10 shown differs only in that: Figure 4FThe receiving portion 150 of the insulating housing 100 of the illustrated electrical connector 10 includes a reinforcing beam 175. The reinforcing beam 175 is disposed at the middle of the front end of the receiving portion 150 and extends between the first wall 151 and the second wall 152. This configuration can improve the strength of the receiving portion 150 and prevent the receiving portion 150 from being deformed. The reinforcing beam 175 can be formed integrally with the receiving portion 150.

[0185] In some embodiments, Figure 4A , Figure 4F , Fig.15A and Fig. 15B As shown, the electrical connector 10 may include a connector position assurance (CPA) device configured to lock the electrical connector 10 to a mating electrical connector (eg, the electrical connector 20 ) when the electrical connector 10 is mated with the mating electrical connector.

[0186] like Fig.15A As shown, the receiving portion 150 may include a groove 178, which is recessed into the first wall 151 along the vertical direction ZZ from the outer surface 151a of the first wall 151 and extends along the transverse direction XX. The groove 178 may extend to the base 110 along the transverse direction XX. The groove 178 may include a bottom wall 178c and a first side wall 178a and a second side wall 178b opposite to each other in the longitudinal direction YY. The groove 178 may also include a first protrusion 179a protruding from the first side wall 178a of the groove 178 along the longitudinal direction YY, a second protrusion 179b protruding from the second side wall 178b of the groove 178 along the longitudinal direction YY, and a third protrusion 179c protruding from the bottom wall 178c of the groove 178 along the vertical direction ZZ.

[0187] Please continue to see Fig.15A, the CPA device may include a cantilever mechanism 180. The cantilever mechanism 180 may be an integral part of the accommodating portion 150. The cantilever mechanism 180 may include a first elastic beam 181 and a second elastic beam 182. The first elastic beam 181 and the second elastic beam 182 extend from the bottom wall 178c toward the base 110 along the transverse direction XX, respectively. The first elastic beam 181 and the second elastic beam 182 may be cantilever beams. The first elastic beam 181 includes a first end 181a and a second end 181b opposite to each other in the transverse direction XX. The first end 181a is configured to be fixed and connected to the bottom wall 178c. The second end 181b is configured to be unfixed and spaced apart from the bottom wall 178c in the vertical direction ZZ. The second elastic beam 182 includes a first end 182a and a second end 182b opposite to each other in the transverse direction XX. The first end 182a is configured to be fixed and connected to the bottom wall 178c. The second end 182b is configured to be unfixed and spaced apart from the bottom wall 178c in the vertical direction ZZ. The first elastic beam 181 and the second elastic beam 182 are spaced apart from each other in the longitudinal direction YY and define a receiving space therebetween. The first elastic beam 181 and the second elastic beam 182 may be parallel to each other.

[0188] The overhang mechanism 180 may also include a third beam 183 and a fourth beam 184. The third beam 183 extends from the second end 181b of the first elastic beam 181 to the second end 182b of the second elastic beam 182 along the longitudinal direction YY. In other words, the third beam 183 connects the second end 181b of the first elastic beam 181 with the second end 182b of the second elastic beam 182. The fourth beam 184 may also extend along the longitudinal direction YY and include a first end and a second end (not shown) opposite to each other in the longitudinal direction YY. The first end of the fourth beam 184 is connected to the first elastic beam 181 between the first end 181a and the second end 181b of the first elastic beam 181, and the first end of the fourth beam 184 is connected to the second elastic beam 182 between the first end 182a and the second end 182b of the second elastic beam 182. The third beam 183 and the fourth beam 184 may be parallel to each other. As will be described in detail below, the fourth beam 184 is configured to engage with a mating latch portion of a mating electrical connector (eg, the electrical connector 20 ) when the electrical connector 10 is mated with the mating electrical connector, thereby locking the electrical connector 10 to the mating electrical connector.

[0189] In some embodiments, Figure 4A , Figure 4B , Figure 4F and Fig. 15BAs shown, the CPA device may further include a latch member 400. The latch member 400 may be configured to lock the fourth beam 184 in a position engaged with the mating snap portion of the mating electrical connector when the electrical connector 10 is mated with a mating electrical connector (e.g., the electrical connector 20), thereby ensuring that the electrical connector 10 is reliably locked to the mating electrical connector. The latch member 400 may also be referred to as a "second latch member". The latch member 400 may be made of an insulating material. Examples of insulating materials suitable for manufacturing the latch member 400 include, but are not limited to, plastic, nylon, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO) or polypropylene (PP).

[0190] The latch member 400 may be configured to be disposed in the groove 178 and to be able to be in the groove 178 relative to the cantilever mechanism 180 in the first position ( Figure 4F ) and the second position ( Figure 4A ). Fig. 15B As shown, the latch member 400 may include a base 401 and a first elastic arm 410 and a second elastic arm 420 extending from the base 401 along the transverse direction XX, respectively. The shape of the base 401 may be designed to facilitate engagement by the user's hand so that the latch member 400 moves in the groove 178. The first elastic arm 410 and the second elastic arm 420 are opposite to each other and spaced apart in the longitudinal direction YY. The first elastic arm 410 and the second elastic arm 420 may be configured to engage with the first side wall 178a and the second side wall 178b of the groove 178, respectively, to keep the latch member 400 in the groove 178. The first elastic arm 410 may include a first protrusion 411 protruding along the vertical direction ZZ and a second protrusion 412 protruding along the transverse direction XX, and the second elastic arm 420 may include a first protrusion 421 protruding along the vertical direction ZZ and a second protrusion 422 protruding along the transverse direction XX. The second protrusions 412 and 422 may have the shape of barbs. The latch member 400 may further include a third elastic arm 430. The third elastic arm 430 extends obliquely from the base 401 along the transverse direction XX and has a protrusion 431 at an end opposite to the base 401. The third elastic arm 430 may also be formed with a slide groove 432, which extends along the transverse direction XX and includes first ends 432a ( Fig. 15B ) and the second end 432b ( Figure 4A ). The third elastic arm 430 may be located between the first elastic arm 410 and the second elastic arm 420 in the longitudinal direction YY.

[0191] like Figure 4A , Figure 4F , Fig.15A and Fig. 15B As shown, when the latch member 400 is disposed in the groove 178, the first elastic arm 410 and the second elastic arm 420 may respectively engage with the first side wall 178a and the second side wall 178b of the groove 178 to retain the latch member 400 in the groove 178. The third elastic arm 430 of the latch member 400 may extend obliquely from the base 401 along the transverse direction XX into a receiving space defined by the first elastic beam 181 and the second elastic beam 182 of the cantilever mechanism 180, so that the protrusion 431 is positioned in the receiving space. The second protrusion 412 of the first elastic arm 410 and the second protrusion 422 of the second elastic arm 420 of the latch member 400 can cooperate with the first protrusion 179a and the second protrusion 179b of the groove 178 respectively, and the slide groove 432 of the third elastic arm 430 of the latch member 400 can cooperate with the third protrusion 179c of the groove 178 to limit the movement range of the latch member 400 in the groove 178 along the lateral direction XX.

[0192] like Figure 4A , Fig.15A and Fig. 15B As shown, when the latch member 400 is placed in the second position, the second protrusion 412 of the first elastic arm 410 and the second protrusion 422 of the second elastic arm 420 of the latch member 400 can be engaged with the first protrusion 179a and the second protrusion 179b of the groove 178, respectively (optionally or additionally, the first end 432a of the slide groove 432 of the third elastic arm 430 can be engaged with the third protrusion 179c) to limit the movement of the latch member 400 away from the extension mechanism 180 along the lateral direction XX. In addition, the first protrusion 411 of the first elastic arm 410 and the first protrusion 421 of the second elastic arm 420 are not engaged with the first elastic beam 181 and the second elastic beam 182 below, and the protrusion 431 of the third elastic arm 430 is positioned between the fourth beam 184 and the third beam 183, thereby unlocking the cantilever mechanism 180 to allow the third beam 183 and the fourth beam 184 of the cantilever mechanism 180 to move toward the bottom wall 178c when biased toward the bottom wall 178c. In this case, biasing the third beam 183 toward the bottom wall 178c can cause the third beam 183 and the fourth beam 184 to move toward the bottom wall 178c. This can cause the fourth beam 184 to disengage from the snap portion of the mating connector when the electrical connector 10 is mated with the mating connector.

[0193] like Figure 4F , Fig.15A and Fig. 15BAs shown, when the latch member 400 is placed in the first position, the second protrusion 412 of the first elastic arm 410 and the second protrusion 422 of the second elastic arm 420 of the latch member 400 can be respectively disengaged from the first protrusion 179a and the second protrusion 179b of the groove 178. The second end 432b of the slide groove 432 of the third elastic arm 430 can be engaged with the third protrusion 179c to restrict the latch member 400 from moving toward the suspension mechanism 180 along the transverse direction XX. In addition, the first protrusion 411 of the first elastic arm 410 and the first protrusion 421 of the second elastic arm 420 of the latch member 400 can respectively engage the first elastic beam 181 and the second elastic beam 182 below the first elastic beam 181 and the second elastic beam 182, and the protrusion 431 of the third elastic arm 430 is positioned to engage with the fourth beam 184 on the side of the fourth beam 184 opposite to the third beam 183, thereby locking the overhang mechanism 180 to prevent the third beam 183 and the fourth beam 184 from moving toward the bottom wall 178c when biased toward the bottom wall 178c. In this case, biasing the third beam 183 toward the bottom wall 178c cannot cause the third beam 183 and the fourth beam 184 to move toward the bottom wall 178c. This can ensure that the fourth beam 184 is in reliable engagement with the snap portion of the mating connector when the electrical connector 10 is mated with the mating connector.

[0194] With this configuration, the latch member 400 can be selectively placed in the pre-lock position ( Figure 4A The second position shown) and the locked position ( Figure 4F 178c). In the pre-locked position, the latch member 400 is reliably held on the insulating housing 100, and the cantilever mechanism 180 is unlocked to allow the third beam 183 and the fourth beam 184 of the cantilever mechanism 180 to move toward the bottom wall 178c when biased toward the bottom wall 178c. In the locked position, the latch member 400 is also reliably held on the insulating housing 100, and the cantilever mechanism 180 is locked to prevent the third beam 183 and the fourth beam 184 from moving toward the bottom wall 178c when biased toward the bottom wall 178c. This configuration enables the electrical connector 10 to meet the requirements of specifications such as USCAR. Since the latch member 400 can be pre-locked in place, it is possible to avoid losing the latch member 400 when the electrical connector 10 is mated with a mating connector, and the assembly efficiency of the electronic system 1 can be improved.

[0195] The specific process of operating the suspension mechanism 180 and the latch member 400 to lock the electrical connector 10 to the electrical connector 20 and unlock the electrical connector 10 from the electrical connector 20 will be described below in conjunction with an example in which the electrical connector 10 and the electrical connector 20 are combined into a connector assembly.

[0196] In some embodiments, the first end 181a of the first elastic beam 181 and the first end 182a of the second elastic beam 182 of the cantilever mechanism 180 may be reinforced, for example, by adding glue (for example, Figure 4A The reinforcement portion 185 shown is provided to improve the reliability of the suspension mechanism 180.

[0197] Although the electrical connector 10 is described above as having two wiring members, it should be understood that the present application is not limited thereto. In other embodiments, the electrical connector 10 may include more (e.g., three, four, five) wiring members. The structure of the insulating housing 100 may be adjusted accordingly to provide more wiring members. For example, the insulating housing 100 may have more first channels 111.

[0198] Although the latch member 300 is described above as being configured to selectively engage with the side edge of the cable member to achieve pre-locking and locking functions, it should be understood that the present application is not limited thereto. The latch member 300 can be any suitable type of latch member suitable for retaining the connection end of the cable member in the insulating housing.

[0199] Although it is described above that the latch member 300 has two first arms 310, it should be understood that the present application is not limited thereto. In other embodiments, the latch member 300 may have only a single first arm 310, or more than two first arms 310. The number of second channels of the insulating housing 100 and the number of notches of the wiring member may be adjusted accordingly. For example, the wiring member may have multiple notches at each side edge, or may have one or more notches at only a single side edge.

[0200] Although it is described above that the latch member 300 has two second arms 320, it should be understood that the present application is not limited thereto. In other partial embodiments, the latch member 300 may have only a single second arm 320. For example, the latch member 300 has a single first arm 310 and a single second arm 320 to achieve the aforementioned pre-locking and locking functions. In other partial embodiments, the latch member 300 may have more than two second arms 320. The number of the slots of the insulating housing 100 may be adjusted accordingly.

[0201] Socket Connectors

[0202] FIG. 9A to FIG. 14 The configuration of the socket connector is shown in detail, wherein: FIG. 9A to FIG. 11 A first type of socket connector is shown, which is indicated by electrical connector 20, and FIG. 12A to FIG. 14 A second version of a socket connector is shown, which is indicated as electrical connector 20'.

[0203] First refer to FIG. 9A to FIG. 11The configuration of the electrical connector 20 is described in detail.

[0204] like Fig. 9A and Fig. 9B As shown, the electrical connector 20 may include an insulating housing 500 , a plurality of conductive terminals 600 , and a fixing sheet 700 .

[0205] A plurality of conductive terminals 600 are disposed in the insulating housing 500. The insulating housing 500 provides support and protection for the plurality of conductive terminals 600. The insulating housing 500 may be made of an insulating material. Examples of insulating materials suitable for making the insulating housing 500 include, but are not limited to, plastic, nylon, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO) or polypropylene (PP).

[0206] The electrical connector 20 may be configured to be disposed on a surface 31 of a circuit board 30 and to be connected to a conductive structure (eg, Figure 1C The insulating housing 500 may be configured to be placed on the surface 31 of the circuit board 30. The insulating housing 500 may include a slot 530 for receiving the fixing sheet 700. Figure 1A and Figure 1B As shown, the fixing sheet 700 can be inserted into the corresponding slot 530 and fix the insulating housing 500 on the circuit board 30. The fixing sheet 700 can be made of metal material.

[0207] like 9A to 9E and Fig.11 As shown, the insulating housing 500 may include a base 510 and a tongue 520 extending from the base 510 along the transverse direction XX. The tongue 520 extends from a first surface (front surface) 511 of the base 510 along the transverse direction XX. The tongue 520 may include a first surface 521 and a second surface 522 opposite to each other in a vertical direction ZZ perpendicular to the transverse direction XX. The base 510 may include a top surface 515 and a bottom surface 516 opposite to each other in the vertical direction ZZ. When the electrical connector 20 is mounted on the circuit board 30, the bottom surface 516 of the base 510 faces the surface 31 of the circuit board, and the second surface 522 of the tongue 520 is closer to the surface 31 of the circuit board 30 and the bottom surface 516 of the base 510 in the vertical direction ZZ than the first surface 521.

[0208] The conductive terminal 600 may be formed of a conductive material. The conductive material suitable for manufacturing the conductive terminal 600 may be a metal material, such as a copper alloy. The conductive terminal may also be referred to as a "terminal", "conductor" or "conductive element".

[0209] Each conductive terminal 600 includes a mating end having a mating contact portion, a mounting end opposite to the mating end, and a middle portion connecting the mating end and the mounting end. Fig. 9B As shown, the plurality of conductive terminals 600 may include a plurality of first conductive terminals 610 and a plurality of second conductive terminals 620. The plurality of first conductive terminals 610 are arranged in a first row R1 along a longitudinal direction YY perpendicular to the transverse direction XX and the vertical direction ZZ. In the first row R1, the plurality of first conductive terminals 610 are aligned with each other and spaced apart in the longitudinal direction YY. The plurality of second conductive terminals 620 are arranged in a second row R2 along the longitudinal direction YY. In the second row R2, the plurality of second conductive terminals 620 are aligned with each other and spaced apart in the longitudinal direction YY. The first row R1 and the second row R2 may be spaced apart from each other in the vertical direction ZZ. The first row R1 may be located above the second row R2 in the vertical direction ZZ (relative to the surface 31 of the circuit board 30). The first row R1 may also be referred to as a "top row", and the first conductive terminals 610 may also be referred to as "upper conductive elements". The second row R2 may also be referred to as a "bottom row", and the second conductive terminals 620 may also be referred to as "lower conductive elements".

[0210] Fig. 10A and Fig. 10B The configurations of the first conductive terminal 610 and the second conductive terminal 620 are shown respectively. Fig. 10A As shown, the first conductive terminal 610 includes a mating end 611 having a mating contact portion 611a, a mounting end 612 opposite to the mating end, and a middle portion 613 connecting the mating end 611 and the mounting end 612. Fig. 10B As shown, the second conductive terminal 620 includes a mating end 621 having a mating contact portion 621 a , a mounting end 622 opposite to the mating end 621 , and a middle portion 623 connecting the mating end 621 and the mounting end 622 .

[0211] like FIG. 3A to FIG. 3B , Fig. 9A , Fig. 9C and Fig.9DAs shown, the insulating housing 500 may include a plurality of first channels 505 and a plurality of second channels 506 extending from the base 510 along the transverse direction XX into the tongue 520. Each first channel 505 may extend from a first side of the base 510 opposite to the tongue 520 along the transverse direction XX into the tongue 520, and open at a first surface 521 of the tongue 520. Each second channel 506 may extend from the first side of the base 510 along the transverse direction XX into the tongue 520, and open at a second surface 522 of the tongue 520. The middle portion 613 and the mating end 611 of each of the plurality of first conductive terminals 610 are inserted into the corresponding first channel 505 from the first side of the base 510, the middle portion 613 is disposed in the base 510, and the mating end 611 extends into the tongue 520, so that the mating contact portion 611a protrudes from the first surface 521. Similarly, the middle portion 623 and the mating end 621 of each of the plurality of second conductive terminals 620 are inserted into the corresponding second channel 506 from the first side of the base 510, the middle portion 623 is disposed in the base 510, and the mating end 621 extends into the tongue 520, so that the mating contact portion 621a protrudes from the second surface 522. With this configuration, as will be described in detail below, when the electrical connector 10 and the electrical connector 20 are mated, the mating contact portions 611a of the plurality of first conductive terminals 610 can establish separable electrical contacts with the plurality of conductive contacts 203 of the first wiring member 200A of the electrical connector 10, and the mating contact portions 621a of the plurality of second conductive terminals 620 can establish separable electrical contacts with the plurality of conductive contacts 203 of the second wiring member 200B of the electrical connector 10.

[0212] like Figure 2 and Fig. 9A As shown, the mating ends 611 of the plurality of first conductive terminals 610 and the mating ends 621 of the plurality of second conductive terminals 620 can be staggered with each other in the vertical direction ZZ. This arrangement enables the first row R1 and the second row R2 to be arranged at a smaller spacing in the vertical direction ZZ, while still ensuring a sufficient spacing between the mating ends 611 of the first conductive terminals 610 and the mating ends 621 of the second conductive terminals 620. This arrangement can reduce the size (i.e., height) of the electrical connector 20 in the vertical direction ZZ. This is conducive to the miniaturization of the electrical connector 20 and can reduce the space occupied by the electrical connector 20 on the circuit board 30.

[0213] In some embodiments, Fig. 10AAs shown, for each first conductive terminal 610, the mating end 611 may include a first beam 631 and a second beam 632, which extend from the middle portion 613 along the transverse direction XX in a plane perpendicular to the longitudinal direction YY. That is, the first beam 631 and the second beam 632 may be coplanar with each other. The first beam 631 and the second beam 632 are spaced apart from each other in the vertical direction ZZ. The first beam 631 has a first contact portion 641, and the second beam 632 has a second contact portion 642. The first beam 631 is longer than the second beam 632 in the transverse direction XX, so that the first contact portion 641 of the first beam 631 and the second contact portion 642 of the second beam 632 are aligned with each other and spaced apart in the transverse direction XX. The first contact portion 641 of the first beam 631 is farther from the middle portion 613 of the first conductive terminal 610 than the second contact portion 642 of the second beam 632 in the transverse direction XX. As Fig.9D As shown, when the first conductive terminal 610 is disposed in the insulating housing 500, the first contact portion 641 of the first beam 631 and the second contact portion 642 of the second beam 632 protrude from the first surface 521 and are aligned and spaced apart from each other in the transverse direction XX, and the first contact portion 641 of the first beam 631 is closer to the front end 520a of the tongue 520 opposite to the base 510 than the second contact portion 642 of the second beam 632. The first beam 631 and the second beam 632 may be elastic beams. The first contact portion 641 of the first beam 631 and the second contact portion 642 of the second beam 632 together constitute the mating contact portion 611a of the mating end 611 of the first conductive terminal 610.

[0214] The double-beam double-contact configuration of the first conductive terminal 610 can improve the reliability of the electrical connection of the electrical connector 20 and effectively prevent instantaneous disconnection. In addition, the configuration of the first conductive terminal 610 can improve the current carrying capacity of the first conductive terminal 610, so that the electrical connector 20 can meet the requirements of transmitting large currents. In addition, the configuration of the first conductive terminal 610 can increase the contact density of the electrical connector 20, which is conducive to the miniaturization of the electrical connector 20.

[0215] like Fig. 10A As shown, the first beam 631 of each first conductive terminal 610 includes a first end 631a and a second end 631b opposite to each other, and a first straight section 631c connecting the first end 631a and the second end 631b. The first end 631a is connected to the middle portion 613, and the second end 631b is configured to be unfixed. In other words, the first beam 631 is a cantilever beam. The first straight section 631c extends obliquely from the first end 631a to the second end 631b toward the second beam 632 relative to the transverse direction XX. The first contact portion 641 of the first beam 631 is located at the second end 631b and protrudes from the first straight section 631c in the vertical direction ZZ.

[0216] Please continue to see Fig. 10A , the second beam 632 of each first conductive terminal 610 includes a third end 632a and a fourth end 632b opposite to each other, a curved section 632c extending from the third end 632a, and a second straight section 632d connecting the curved section 632c and the fourth end 632b. The third end 632a is connected to the middle portion 613, and the fourth end 632b is configured to be unfixed. In other words, the second beam 632 is a cantilever beam. The curved section 632c of the second beam 632 is bent from the third end 632a toward the first beam 631, so that the second straight section 632d and the fourth end 632b are located between the middle portion 613 of the first conductive terminal 610 and the second end 631b of the first beam 631 in the transverse direction XX. The second straight section 632d extends from the curved section 632c to the fourth end 632b. The second contact portion 642 is located at the fourth end 632b and protrudes from the second straight section 632d in the vertical direction ZZ.

[0217] Through this configuration, when the second beam 632 is biased to deflect toward the first beam 631 in the vertical direction ZZ, the first beam 631 can prevent the second beam 632 from being excessively deformed, thereby protecting the second beam 632. In addition, such shapes of the first beam 631 and the second beam 632 of the first conductive terminal 610 can provide a longer force arm in a limited space, thereby improving the consistency of the contact force provided by the first beam 631 and the second beam 632.

[0218] like Fig. 10A and Fig. 10C As shown, for each first conductive terminal 610, the first contact portion 641 of the first beam 631 has a convex shape and includes a first leading face 641a (which is adjacent to the front end 520a of the tongue 520 in the transverse direction XX when the first conductive terminal 610 is disposed in the insulating housing 500) and a first following face 641b (which is away from the front end 520a of the tongue 520 in the transverse direction XX when the first conductive terminal 610 is disposed in the insulating housing 500). The first leading face 641a can be formed as an inclined guiding face. This structure can guide the insertion of the first wiring member 200A when the electrical connector 10 is mated with the electrical connector 20, thereby preventing the insertion force (mating force) from being too large and damaging the first contact portion 641 and the conductive contact 203. Alternatively or additionally, the first following face 641b can be formed as an inclined guiding face. This structure can guide the withdrawal of the first cable member 200A when the electrical connector 10 is unmated from the electrical connector 20 , thereby preventing the first contact portion 641 and the conductive contact 203 from being damaged due to excessive un-mating force.

[0219] Alternatively or additionally, such as Fig. 10A As shown, similar to the first contact portion 641 of the first beam 631, the second contact portion 642 of the second beam 632 may have a convex shape and include a second leading face 642a (which is adjacent to the front end 520a of the tongue 520 in the transverse direction XX when the first conductive terminal 610 is disposed in the insulating housing 500) and a second following face 642b (which is away from the front end 520a of the tongue 520 in the transverse direction XX when the first conductive terminal 610 is disposed in the insulating housing 500). The second leading face 642a may be formed as an inclined guiding face. This structure can guide the insertion of the first wiring member 200A when the electrical connector 10 is mated with the electrical connector 20, thereby preventing the insertion force from being too large and damaging the second contact portion 642 and the conductive contact 203. Alternatively or additionally, the second following face 642b may be formed as an inclined guiding face. This structure can guide the withdrawal of the first cable member 200A when the electrical connector 10 is disengaged from the electrical connector 20 , thereby preventing the second contact portion 642 and the conductive contact 203 from being damaged due to excessive withdrawal force.

[0220] In some embodiments, Fig. 10C As best shown, the second contact portion 642 of the second beam 632 has a convex shape and includes a first end section 6421 and a second end section 6422 that are opposite to each other in the vertical direction ZZ, and a transition section 6423 that connects the first end section 6421 and the second end section 6422. The first end section 6421 is connected to the fourth end 632b of the second beam 632 and has a constant first width W1 in the longitudinal direction YY. The second end section 6422 has a constant second width W2 in the longitudinal direction YY. The second width W2 is smaller than the first width W1. The cross section of the transition section 6423 perpendicular to the transverse direction XX has an isosceles trapezoidal shape, and the width of the transition section 6423 in the longitudinal direction YY tapers from the first width W1 to the second width W2. Alternatively or additionally, the shape of the first contact portion 641 of the first beam 631 may be similar to the shape of the second contact portion 642 of the second beam 632. For the sake of brevity, the details of these identical parts will not be repeated. Such shapes of the first contact portion 641 of the first beam 631 and the second contact portion 642 of the second beam 632 can improve the contact reliability of the first conductive terminal 610 and can be conveniently processed to have sufficient strength.

[0221] In some embodiments, Fig. 10BAs shown, similar to the first conductive terminal 610, the second conductive terminal 620 may have a double-beam double-contact configuration. Specifically, the configuration of the mating end 621 of the second conductive terminal 620 may be similar to the configuration of the mating end 611 of the first conductive terminal 610. The mating end 621 of the second conductive terminal 620 may include a third beam 633 and a fourth beam 634. The third beam 633 and the fourth beam 634 extend from the middle portion 613 along the transverse direction XX in a plane perpendicular to the longitudinal direction YY, and are spaced apart from each other in the vertical direction ZZ. The shapes of the third beam 633 and the fourth beam 634 may be similar to the shapes of the first beam 631 and the second beam 632, respectively. In addition, the arrangement relationship of the third beam 633 and the fourth beam 634 may be similar to the arrangement relationship of the first beam 631 and the second beam 632. For the sake of brevity, the details of these identical parts will not be repeated.

[0222] The double-contact configuration of the first conductive terminal 610 and the second conductive terminal 620 can provide more contact points in a limited space, so that the electrical connector 20 can meet the requirement of a high pin count.

[0223] It should be understood that the specific configuration of the mating portion of the first conductive terminal 610 and the second conductive terminal 620 is not limited to the configuration described above. In other embodiments, the mating end 621 of the first conductive terminal 610 and the second conductive terminal 620 may have a single beam and a single contact, or may have more beams and more contacts.

[0224] like 9A to 9E and Fig.11 As shown, the insulating housing 500 also includes a receiving portion 540, which extends from the first surface 511 of the base 510 along the lateral direction XX and encloses an accommodating space 550. The tongue 520 is positioned in the accommodating space 550. The accommodating space 550 is open at the end opposite to the base 510. Through this configuration, the mating ends 621 of the first conductive terminal 610 and the second conductive terminal 620 can be positioned in the accommodating space 550 and protected by the accommodating portion 540 to prevent being touched by the user's fingers or tools, thereby preventing the user from getting an electric shock or avoiding a short circuit. This configuration can improve the safety and reliability of the electronic system 1 using the electrical connector 20.

[0225] Exemplarily, the front end 520a of the tongue portion 520 may be retracted into the accommodation space 550 by a certain distance in the transverse direction XX relative to the opening of the accommodation portion 540. For example, the distance may be greater than or equal to 1 mm.

[0226] The receiving portion 540 of the insulating housing 500 may include a first wall 541 and a second wall 542 that are opposite to each other and spaced apart in the vertical direction ZZ, and a third wall 543 and a fourth wall 544 that are opposite to each other and spaced apart in the longitudinal direction YY. The first wall 541, the second wall 542, the third wall 543, and the fourth wall 544 enclose an accommodating space 550. The accommodating space 550 may be used as a slot of the insulating housing 500 to receive a housing of another electrical connector that mates with the electrical connector 20. For example, the accommodating space 550 may receive the accommodating portion 150 of the insulating housing 100 of the electrical connector 10.

[0227] like Fig. 9A and Fig. 9B As shown, the first wall 541 and the third wall 543 of the insulating shell 500 are connected to each other at the first corner, the first wall 541 and the fourth wall 544 are connected to each other at the second corner, the second wall 542 and the third wall 543 are connected to each other at the third corner, and the second wall 542 and the fourth wall 544 are connected to each other at the fourth corner.

[0228] In some embodiments, the receiving portion 540 of the insulating housing 500 may include a first groove 561 recessed into the first wall 541 from the receiving space 550 along the vertical direction ZZ at the first corner, and a second groove 562 recessed into the first wall 541 from the receiving space 550 along the vertical direction ZZ at the second corner. The first groove 561 and the second groove 562 extend along the transverse direction XX, respectively. The first groove 561 and the second groove 562 are respectively configured to receive the first rib 171 and the second rib 172 of the insulating housing 100 of the electrical connector 10. With this configuration, the receiving portion 150 of the insulating housing 100 of the electrical connector 10 can be inserted into the receiving space 550 of the receiving portion 540 of the insulating housing 500 of the electrical connector 20 only by aligning the first rib 171 and the second rib 172 of the insulating housing 100 with the first groove 561 and the second groove 562 in the transverse direction XX, respectively. This configuration can prevent the electrical connector 10 from being inserted into the housing of the electrical connector 20 in a skewed orientation, thereby providing protection for the matching conductive structures of the electrical connector 10 and the electrical connector 20, and can improve the hot plugging capability of the electrical connector 20. In addition, during the insertion of the accommodating portion 150 into the accommodating space 550 of the accommodating portion 540, the first groove 561 and the second groove 562 can play a role in guiding the insertion. In addition, the first rib 171 and the second rib 172 cooperate with the first groove 561 and the second groove 562 to ensure that the electrical connector 10 is inserted into the electrical connector 20 in a unique orientation. Optionally or additionally, the insulating housing 500 may include grooves at the third corner and the fourth corner.

[0229] like Fig. 9AAs shown, the tongue 520 can be spaced apart from the third wall 543 and the fourth wall 544 in the transverse direction XX, and can be spaced apart from the first wall 541 and the second wall 542 in the vertical direction ZZ. When the receiving portion 150 of the insulating housing 100 of the electrical connector 10 is inserted into the receiving space 550 of the receiving portion 540 of the insulating housing 500 of the electrical connector 20, the first wall 151 of the insulating housing 100 and the first wiring member 200A are located between the tongue 520 and the first wall 541, the second wall 152 of the insulating housing 100 and the second wiring member 200B are located between the tongue 520 and the second wall 542, the third wall 153 of the insulating housing 100 is located between the tongue 520 and the third wall 543, and the fourth wall 154 of the insulating housing 100 is located between the tongue 520 and the fourth wall 544.

[0230] In some embodiments, Fig. 9A and Fig.9E As shown, the insulating housing 500 may include a first recess 563 and a second recess 564 respectively recessed into the first surface 511 of the base 510 from the accommodating space 550 along the transverse direction XX at opposite ends of the tongue 520 in the longitudinal direction YY. The first recess 563 and the second recess 564 are respectively configured to receive the first protrusion 173 and the second protrusion 174 of the insulating housing 100 of the electrical connector 10. This configuration can increase the size of the accommodating portion 150 in the mating direction without increasing the overall width of the electrical connector 10 and the electrical connector 20. When the accommodating portion 150 of the electrical connector 10 is inserted into the housing of the electrical connector 20, this configuration can guide the accommodating portion 150 to be in the correct orientation and reduce its shaking amount, thereby improving the hot plugging capability of the electrical connector 10. In addition, if the accommodating portion 150 of the electrical connector 10 is inserted into the housing of the electrical connector 20 in a skewed orientation, this configuration can prevent the conductive parts of the electrical connector 10 and the electrical connector 20 from contacting each other to protect the circuit from damage. This can improve the hot plug capability and reliability of the electrical connector 10 .

[0231] In some embodiments, Figure 1C and Fig. 10DAs shown, the base 510 may include a third surface 513 and a fourth surface 514 at a side opposite to the tongue 520. The third surface 513 and the fourth surface 514 are both perpendicular to the transverse direction XX and face the same direction. The fourth surface 514 is farther from the tongue 520 than the third surface 513 in the transverse direction XX. That is, the third surface 513 and the fourth surface 514 are spaced apart from each other in the transverse direction XX. The mounting ends 612 of the plurality of first conductive terminals 610 extend from the third surface 513 of the base 510 along the transverse direction XX, and the mounting ends 622 of the plurality of second conductive terminals 620 extend from the fourth surface 514 of the base 510 along the transverse direction XX. That is, the mounting ends 612 of the plurality of first conductive terminals 610 and the mounting ends 622 of the plurality of second conductive terminals 620 extend from different reference surfaces of the base 510 spaced apart in the transverse direction XX. In other words, the mounting ends 612 of the plurality of first conductive terminals 610 and the mounting ends 622 of the plurality of second conductive terminals 620 are inserted into the base 510 from different reference planes of the base 510 that are spaced apart in the transverse direction XX.

[0232] This configuration can increase the creepage distance between the mounting ends 612 of the plurality of first conductive terminals 610 and the mounting ends 622 of the plurality of second conductive terminals 620, thereby allowing the plurality of first conductive terminals 610 and the plurality of second conductive terminals 620 to be arranged at a closer pitch and improving the insulation withstand voltage performance of the electrical connector 20. This makes it possible to reduce the size of the electrical connector 20 in the transverse direction XX and / or the longitudinal direction YY. This is conducive to the miniaturization of the electrical connector 20 and can reduce the occupied space of the electrical connector 20 on the circuit board 30.

[0233] In some embodiments, Figure 1C and Fig. 10D As shown, the base 510 may include a plurality of bosses 570 protruding from the third surface 513 along the transverse direction XX. The plurality of bosses 570 are aligned and spaced apart from each other in the longitudinal direction YY. Each boss 570 includes a first face 571, which is parallel to the third surface 513 and faces the same direction as the third surface 513. Since the boss 570 protrudes from the third surface 513, the first face 57 of the boss 570 is spaced apart from the third surface 513 in the transverse direction XX, and the first face 57 of the boss 570 is farther from the tongue 520 than the third surface 513 in the transverse direction XX. The first faces 571 of the plurality of bosses 570 may be coplanar. Each adjacent two bosses 570 in the plurality of bosses 570 define a gap G therebetween along the longitudinal direction YY. Each boss 570 also has a side face 572, which deviates from the plane defined by the bottom surface 516 of the base 510.

[0234] The fourth surface 514 of the base 510 includes the first faces 571 of the plurality of bosses 570. That is, the fourth surface 514 of the base 510 is a discontinuous surface, which may be formed by the first faces 571 of the plurality of bosses 570. The mounting end 622 of each of the plurality of second conductive terminals 620 extends from the first face 571 of a corresponding one of the plurality of bosses 570 of the base 510 along the transverse direction XX. As described above, the mounting ends 612 of the plurality of first conductive terminals 610 extend from the third surface 513 of the base 510 along the transverse direction XX. That is, the mounting ends 612 of the plurality of first conductive terminals 610 and the mounting ends 622 of the plurality of second conductive terminals 620 extend from different reference surfaces of the base 510 that are spaced apart in the transverse direction XX. By this configuration, the creepage distance between the mounting ends 612 of the plurality of first conductive terminals 610 and the mounting ends 622 of the plurality of second conductive terminals 620 can be increased.

[0235] In some embodiments, the electrical connector 20 is a right-angle connector. For the plurality of conductive terminals 600, the mounting end of each conductive terminal includes a first section extending from the base 510 along the lateral direction XX from the middle portion, a second section configured to be mounted to the circuit board 30, and a third section connecting the first section and the second section. The third section extends from the first section toward a plane defined by the bottom surface 516 of the base 510 so that the second section can be mounted to the circuit board 30.

[0236] Specifically, if Fig. 10A and Fig. 10D As shown, the mounting end 612 of each first conductive terminal 610 includes a first section 6121, a second section 6122, and a third section 6123 connecting the first section 6121 and the second section 6122. The first section 6121 extends from the middle portion 613 along the transverse direction XX to extend from the third surface 513 of the base 510 of the insulating housing 500. The second section 6122 is configured to be mounted to the circuit board 30. The second section 6122 may also be referred to as a mounting portion. Fig. 10B and Fig. 10D As shown, the mounting end 622 of each second conductive terminal 620 includes a first section 6221, a second section 6222, and a third section 6223 connecting the first section 6221 and the second section 6222. The first section 6221 extends from the middle portion 623 along the transverse direction XX to extend from the base 510 of the insulating housing 500. The second section 6222 is configured to be mounted to the circuit board 30. The second section 6222 may also be referred to as a mounting portion.

[0237] In some embodiments, Fig. 10DAs shown, the third segment 6123 of the mounting end 612 of each of the plurality of first conductive terminals 610 extends along the vertical direction ZZ through the gap G between the corresponding two adjacent boss portions 570, so that the third segments 6123 of each two adjacent first conductive terminals 610 are separated by the boss portion 570. For example, the third segment 6123 of each first conductive terminal 610 can be a straight segment. Fig. 10D It is shown that a portion of the third segment 6123 of the first conductive terminal 610 extends through the gap G along the vertical direction ZZ, but it should be understood that in other embodiments, the entire length of the third segment 6123 of the first conductive terminal 610 may be located in the gap G. Therefore, in the present application, at least a portion of the third segment 6123 of the first conductive terminal 610 may extend through the gap G between two adjacent boss portions 570 along the vertical direction ZZ.

[0238] This configuration can increase the creepage distance between the mounting ends 612 of the plurality of first conductive terminals 610 and the mounting ends 622 of the plurality of second conductive terminals 620, thereby allowing the plurality of first conductive terminals 610 and the plurality of second conductive terminals 620 to be arranged at a closer pitch and improving the insulation withstand voltage performance of the electrical connector 20. This makes it possible to reduce the size of the electrical connector 20 in the transverse direction XX and / or the longitudinal direction YY. This is conducive to the miniaturization of the electrical connector 20 and can reduce the occupied space of the electrical connector 20 on the circuit board 30.

[0239] In one of these embodiments, Fig. 10D As shown, the first segment 6121 and the third segment 6123 of the first conductive terminal 610 do not extend beyond the first surface 571 of the boss portion 570 in the transverse direction XX.

[0240] In some embodiments, Fig. 10DAs shown, the conductive structure on the circuit board 30 configured to establish an electrical connection with the conductive terminal can be a conductive pad 32. In this case, the second segment of the mounting end of each of the plurality of conductive terminals 600 can be configured to be soldered to the conductive pad 32 of the circuit board 30. The soldering surface of the second segment 6122 of the mounting end 612 of the plurality of first conductive terminals 610 and the soldering surface of the second segment 6222 of the mounting end 622 of the plurality of second conductive terminals 620 can be coplanar with a plane perpendicular to the vertical direction ZZ. The second segments 6122 of the mounting ends 612 of the plurality of first conductive terminals 610 are arranged in a row in the longitudinal direction YY, and the second segments 6222 of the mounting ends 622 of the plurality of second conductive terminals 620 are arranged in a row in the longitudinal direction YY. The second segments 6122 of the plurality of first conductive terminals 610 are closer to the third surface 513 than the second segments 6222 of the plurality of second conductive terminals 620. The second segments 6122 of the plurality of first conductive terminals 610 and the second segments 6222 of the plurality of second conductive terminals 620 may be staggered in the lateral direction XX. This configuration can facilitate flatness detection after soldering the second segments 6122 and 6222 of the mounting ends 612 and 622 to the conductive pads 32 of the circuit board 30.

[0241] like Fig. 9A and Fig. 9B As shown, the middle portions 613 of the plurality of first conductive terminals 610 and the middle portions 623 of the plurality of second conductive terminals 620 can be staggered from each other in the vertical direction ZZ. This configuration enables the first row R1 and the second row R2 to be arranged at a smaller spacing in the vertical direction ZZ, while still ensuring a sufficient spacing between the middle portions 613 of the first conductive terminals 610 and the middle portions 623 of the second conductive terminals 620. In this way, the size (i.e., height) of the electrical connector 20 in the vertical direction ZZ can be reduced. This is conducive to the miniaturization of the electrical connector 20 and can reduce the space occupied by the electrical connector 20 on the circuit board 30.

[0242] In some embodiments, Fig.11 As shown, the receiving portion 540 of the insulating housing 500 may include a groove 580. The groove 580 is recessed from the receiving space 550 in the first wall 541 along the vertical direction ZZ and extends along the transverse direction XX. The groove 580 includes a bottom wall 581. The receiving portion 540 may also include a snap portion 582 protruding from the bottom wall 581 of the groove 580 into the groove 580. As will be described in detail below, the snap portion 582 may be configured to be engaged by the fourth beam 184 of the electrical connector 10. The snap portion 582 may be arranged near the front edge of the first wall 541. The snap portion 582 may be formed integrally with the first wall 541.

[0243] In some embodiments, Fig.11 As shown, the receiving portion 540 of the insulating housing 500 may include a reinforcing rib 583. The reinforcing rib 583 may protrude from the bottom wall 581 of the groove 580 into the groove 580 and extend along the transverse direction XX. The reinforcing rib 583 may increase the strength of the wall section of the first wall 541 corresponding to the groove 580. Since the reinforcing rib 583 can provide sufficient strength to the wall section of the first wall 541, the wall section may not be bent outwardly convexly like a conventional housing. This is conducive to reducing the height of the electrical connector 20 in the vertical direction ZZ, thereby facilitating the miniaturization of the electrical connector 20.

[0244] See also Fig.15A and Fig. 15B , the fourth beam 184 of the cantilever mechanism 180 of the insulating housing 100 of the electrical connector 10 may include a first notch 184a extending through the fourth beam 184 along the transverse direction XX, and the protrusion 431 of the third elastic arm 430 of the latch member 400 may include a second notch 431a extending through the protrusion 431 along the transverse direction XX. Figure 4A As shown, when the latch member 400 is placed in the second position, the first recess 184a and the second recess 431a are aligned with each other in the transverse direction XX. This allows the reinforcing rib 583 to extend through the first recess 184a and the second recess 431a along the transverse direction XX when the electrical connector 10 and the electrical connector 20 are mated. This configuration of the first recess 184a, the second recess 431a and the reinforcing rib 583 can further reduce the height of the electrical connector 20 in the vertical direction ZZ.

[0245] Although it is described above that the middle portion and the mating end of the conductive terminal 600 are directly inserted into the channel of the insulating housing 500, it should be understood that the present application is not limited thereto. In other embodiments, the insulating housing 500 can be molded around the middle portion and the mating end of the conductive terminal 600, or the conductive terminal 600 can be held by an insulating terminal holding member, and the conductive terminal 600 and the terminal holding member together constitute a terminal assembly and are mounted to the insulating housing 500.

[0246] Although it is described above that the mounting end of the conductive terminal is configured to be soldered to the conductive pad 32 of the circuit board 30, it should be understood that the present application is not limited thereto. In other embodiments, the mounting end can be in any other suitable form, such as a press-fit "eye of needle".

[0247] Although it is described above that the fourth surface 514 of the base 510 is formed by a discontinuous surface, it should be understood that the present application is not limited thereto. In other partial embodiments, the fourth surface 514 of the base 510 can be a continuous surface. In addition, in the case where the conductive terminal 600 is held by an insulating terminal holding member, the terminal holding member is a part of the base 510, so the surface of the terminal holding member is the surface of the base 510.

[0248] Continue to refer to FIG. 12A to FIG. 14 The configuration of the electrical connector 20' is described in detail. FIG. 12A to FIG. 14 As shown, the electrical connector 20' is substantially identical in configuration to the electrical connector 20. FIG. 12A to FIG. 14 The same reference numerals are used to identify the electrical connector 20 ′ and FIG. 9A to FIG. 11 The electrical connector 20 shown has the same or similar parts, and the details of these same or similar parts are not repeated here.

[0249] like Fig. 12A As shown, similar to the electrical connector 20, the electrical connector 20' may include an insulating housing 500, a plurality of conductive terminals 600' and a fixing plate 700. The insulating housing 500 and the fixing plate 700 of the electrical connector 20' are substantially the same as the insulating housing 500 and the fixing plate 700 of the electrical connector 20, respectively. For the sake of brevity, the details of these identical or similar parts are not repeated here.

[0250] like FIG. 12A to FIG. 14 As shown, the electrical connector 20 ′ is different from the electrical connector 20 in that the configuration and arrangement of the plurality of conductive terminals 600 ′ of the electrical connector 20 ′ are different from the configuration and arrangement of the plurality of conductive terminals 600 of the electrical connector 20 .

[0251] Specifically, if FIG. 12A to FIG. 13B As shown, the plurality of conductive terminals 600' includes a plurality of first conductive terminals 610' and a plurality of second conductive terminals 620. The configuration of the second conductive terminals 620 of the electrical connector 20' is the same as the configuration of the second conductive terminals 620 of the electrical connector 20. For the sake of brevity, the details of these identical parts are not repeated here.

[0252] Please continue to see FIG. 12A to FIG. 13B The first conductive terminal 610' of the electrical connector 20' includes a mating end 611 having a mating contact portion 611a, a mounting end 612' opposite to the mating end, and a middle portion 613 connecting the mating end 611 and the mounting end 612. The shapes of the mating end 611 and the middle portion 613 of the first conductive terminal 610' of the electrical connector 20' are the same as the shapes of the mating end 611 and the middle portion 613 of the first conductive terminal 610 of the electrical connector 20. For the sake of brevity, the details of these identical parts are not repeated here.

[0253] Similar to the mounting end 612 of the first conductive terminal 610, the mounting end 612' of the first conductive terminal 610' includes a first section 6121, a second section 6122, and a third section 6123' connecting the first section 6121 and the second section 6122. The first section 6121 extends from the middle portion 613 along the lateral direction XX to extend from the base 510 of the insulating housing 500. The second section 6122 is configured to be mounted to the circuit board 30. The third section 6123' extends from the first section 6121 toward a plane defined by the bottom surface 516 of the base 510 so that the second section 6122 can be mounted to the circuit board 30. The shapes of the first section 6121 and the second section 6122 of the mounting end 612' of the first conductive terminal 610' are the same as the shapes of the first section 6121 and the second section 6122 of the mounting end 612 of the first conductive terminal 610. For the sake of brevity, the details of these identical parts are not repeated here.

[0254] The shape of the third section 6123' of the mounting end 612' of the first conductive terminal 610' is different from the shape of the third section 6123 of the mounting end 612 of the first conductive terminal 610. Specifically, Fig.13A As best shown, the third segment 6123' of the first conductive terminal 610' may be a curved segment and may include a first sub-segment 6123a extending from the first segment 6121 along the longitudinal direction YY, and a second sub-segment 6123b extending from the first sub-segment 6123a along the vertical direction ZZ to the second segment 6122. Such a shape of the third segment 6123' causes the second segment 6122 to be offset relative to the first segment 6121 in the transverse direction XX and the vertical direction ZZ. That is, the second segment 6122 and the first segment 6121 of the mounting end 612' extend along different planes that are perpendicular to the longitudinal direction YY and spaced apart from each other in the longitudinal direction YY. This shape of the third section 6123 ′ enables the second conductive terminal 620 to be disposed directly below the first conductive terminal 610 ′ in such a manner that the mating end 621 of the second conductive terminal 620 and the mating end 611 of the first conductive terminal 610 ′ are aligned with each other in the vertical direction ZZ.

[0255] Fig. 12A , Fig. 12B and Fig.14 FIG. 2 shows the relative positional relationship between the first conductive terminal 610′ and the second conductive terminal 620 of the electrical connector 20′ when they are arranged in the insulating housing 500. Fig. 12A , Fig. 12B and Fig.14As shown, the middle portion 613 of each of the plurality of first conductive terminals 610' and the middle portion 613 of a corresponding one of the plurality of second conductive terminals 620 are aligned with each other in the vertical direction ZZ. In addition, the mating end 611 of each of the plurality of first conductive terminals 610' and the mating end 621 of a corresponding one of the plurality of second conductive terminals 620 are aligned with each other in the vertical direction ZZ.

[0256] At the side of the base 510 opposite to the tongue 520, the first section 6121 of the mounting end 612' of each first conductive terminal 610' is on the side 572 ( Fig. 10D and Fig.14 ) extends from the third surface 513 of the base 510 along the transverse direction XX. The first sub-segment 6123a of the third segment 6123' of the mounting end 612' extends along the side 572 in the longitudinal direction YY (i.e., extends adjacent to the side 572), and the second sub-segment 6123b extends along the vertical direction ZZ through the gap G ( Fig. 10D ) to the second section 6122.

[0257] This configuration can increase the creepage distance between the mounting ends 612' of the plurality of first conductive terminals 610' and the mounting ends 622 of the plurality of second conductive terminals 620 of the electrical connector 20', thereby allowing the mounting ends 612' of the plurality of first conductive terminals 610' and the mounting ends 622 of the plurality of second conductive terminals 620 to be arranged at a closer pitch, and improving the insulation withstand voltage performance of the electrical connector 20'. This makes it possible to reduce the size of the electrical connector 20' in the transverse direction XX and / or the longitudinal direction YY. This is conducive to the miniaturization of the electrical connector 20' and can reduce the occupied space of the electrical connector 20' on the circuit board 30. In addition, this configuration can allow the mating ends 611 of the plurality of first conductive terminals 610' and the mating ends 621 of the plurality of second conductive terminals 620 to align with each other in the vertical direction ZZ.

[0258] In one of these embodiments, the first segment 6121 and the third segment 6123 ′ (including the first sub-segment 6123 a and the second sub-segment 6123 b ) of the mounting end 612 ′ of the first conductive terminal 610 ′ do not extend beyond the first surface 571 of the boss portion 570 in the transverse direction XX.

[0259] Other configurations, modifications, functions and advantages of the electrical connector 20' are the same as those of the electrical connector 20. For the sake of brevity, the details of these same parts are not repeated here.

[0260] Connector components

[0261] The electrical connector 10 and the electrical connector 20 can cooperate with each other to form a connector assembly. Such a connector assembly can provide an electrical connection between the circuit board 3 and another electrical component to achieve signal and / or power transmission. Such a connector assembly may be referred to as a "wire-to-board assembly" or a "wire-to-board connector". For example, such a connector assembly may be used as a BMS connector in a battery management system.

[0262] like Figures 1A to 3B As shown, when the electrical connector 10 and the electrical connector 20 are mated with each other, the tongue 520 of the electrical connector 20 is received in the insulating housing 100 of the electrical connector 10 and is positioned between the connection end 202 of the first wiring member 200A and the connection end 202 of the second wiring member 200B, so that the mating contact portions of the mating ends of the plurality of conductive terminals 600 are in electrical contact with the plurality of conductive contacts 203 of the first wiring member 200A and the plurality of conductive contacts 203 of the second wiring member 200B. Specifically, the mating contact portions 611a of the mating ends 611 of the plurality of first conductive terminals 610 are in electrical contact with the plurality of conductive contacts 203 of the first wiring member 200A, and the mating contact portions 621a of the mating ends 621 of the plurality of second conductive terminals 620 are in electrical contact with the plurality of conductive contacts 203 of the second wiring member 200B. In this way, an electrical connection can be established between the wiring member of the electrical connector 10 and the conductive terminals 600 of the electrical connector 20. When the electrical connector 20 is mounted on the circuit board 30 , the conductive terminals 600 of the electrical connector 20 can establish electrical connections between the cable assembly of the electrical connector 10 and the conductive structures on the circuit board 30 , thereby connecting the cable assembly to the circuit board 30 .

[0263] like Figure 2 As best shown, the tongue 520 of the insulating housing 500 of the electrical connector 20 is received in the receiving space 140 of the insulating housing 100 of the electrical connector 10, and is positioned between the second section 220 of the first wiring member 200A and the second section 220 of the second wiring member 200B of the electrical connector 10. The receiving portion 150 of the insulating housing 100 of the electrical connector 10 is received in the receiving portion 540 of the insulating housing 500 of the electrical connector 20, and is positioned between the tongue 520 and the receiving portion 540 of the insulating housing 500 of the electrical connector 20. This arrangement enables the insulating housing 100 of the electrical connector 10 to be tightly mated with the insulating housing 500 of the electrical connector 20, and can form a labyrinth-type sealing protection between the exterior of the connector assembly and the mating interface of the connector assembly to effectively prevent foreign matter from entering the mating interface.

[0264] The first wall 151 of the electrical connector 10 and the second section 220 of the first wiring member 200A are received between the first wall 541 of the electrical connector 20 and the tongue 520. The second wall 152 of the electrical connector 10 and the second section 220 of the second wiring member 200B are received between the second wall 542 of the electrical connector 20 and the tongue 520. The third wall 153 of the electrical connector 10 is received between the third wall 543 of the electrical connector 20 and the tongue 520. The fourth wall 154 of the electrical connector 10 is received between the fourth wall 544 of the electrical connector 20 and the tongue 520.

[0265] like Figure 2 As shown, the first rib 171 and the second rib 172 of the electrical connector 10 are respectively received in the first groove 561 and the second groove 562 of the electrical connector 20. As described above, this configuration can improve the hot plug capability of the connector assembly.

[0266] The first protrusion 173 and the second protrusion 174 of the electrical connector 10 are respectively received in the first recess 563 and the second recess 564 of the electrical connector 20. As described above, this configuration can improve the hot plug capability and reliability of the connector assembly.

[0267] The first elastic beam 181 and the second elastic beam 182 of the suspension mechanism 180 of the CPA device of the electrical connector 10 extend into the groove 580 of the receiving portion 540 of the electrical connector 20, so that the fourth beam 184 is positioned in the groove 580. The buckle portion 582 of the receiving portion 540 is positioned between the fourth beam 184 and the third beam 183 of the suspension mechanism 180 and engages with the fourth beam 184. In this case, as described above, the latch member 400 can be selectively placed in the pre-locking position ( Figure 4A The second position shown) and the locked position ( Figure 4F 180) to unlock and lock the cantilever mechanism 180. The first notch 184a of the fourth beam 184 can be aligned with the reinforcing rib 583 in the transverse direction XX so that the reinforcing rib 583 extends through the first notch 184a along the transverse direction XX. In addition, when the latch member 400 is placed in the locked position, the first notch 184a and the second notch 431a are aligned with each other in the transverse direction XX. In this case, the first notch 184a and the second notch 431a are both aligned with the reinforcing rib 583 in the transverse direction XX so that the reinforcing rib 583 extends through the first notch 184a and the second notch 431a along the transverse direction XX.

[0268] The electrical connector 10 can be configured to be able to be disengaged from the electrical connector 20 by manual manipulation when the electrical connector 10 and the electrical connector 20 are in mutual mating. Fig. 16BAs shown, the base 110 of the insulating housing 100 of the electrical connector 10 may have an engagement protrusion 188 at one end thereof opposite to the receiving portion 150. The engagement protrusion 188 is configured to be grasped by a user's hand to facilitate moving the electrical connector 10 away from the electrical connector 20. The user may first place the latch member 400 in the second position to unlock the cantilever mechanism 180, then press the third beam 183 of the cantilever mechanism 180 toward the bottom wall 178c, and grasp the engagement protrusion 188 to move the electrical connector 10 away from the electrical connector 20, thereby disengaging the electrical connector 10 from the electrical connector 20.

[0269] Alternatively or additionally, the electrical connector 10 is configured to be able to be manipulated by a tool to disengage the electrical connector 20 when the electrical connector 10 and the electrical connector 20 are in engagement with each other. Fig.15A and Fig.16A As shown, the insulating housing 100 may include a flange portion 190 that protrudes outward from the base 110 along the vertical direction ZZ. Figure 1B As shown, when the electrical connector 10 and the electrical connector 20 are in cooperation with each other, the flange portion 190 abuts against the front edge 541a of the first wall 541 of the accommodating portion 540 in the transverse direction XX. The flange portion 190 includes a first side 190a facing the front edge 541a of the first wall 541, and a first receiving recess 191 and a second receiving recess 192 recessed into the flange portion 190 from the first side 190a along the transverse direction XX.

[0270] FIG. 16A to FIG. 16E An exemplary tool 800 is shown. FIG. 16A to FIG. 16C As shown, the tool 800 may include a tool body 810 and a first leg 811, a second leg 812, and a third leg 813 extending from the tool body 810. The third leg 813 is located between the first leg 811 and the second leg 812. The first leg 811 and the second leg 812 of the tool 800 can be received in the first receiving recess 191 and the second receiving recess 192, respectively, so that the third leg 813 can be aligned with the third beam 183 of the cantilever mechanism 180 in the vertical direction ZZ, and can bias the third beam 183 toward the bottom wall 178c, so that the fourth beam 184 moves toward the bottom wall 178c to disengage from the snap portion 582 of the insulating housing 500 of the electrical connector 20. Fig.16D As shown, by deflecting the tool away from the base (as schematically indicated by arrow 51), the first leg 811 and the second leg 812 of the tool 800 can pry the receiving portion 150 of the insulating housing 100 with the front edge 541a of the first wall 541 as a fulcrum, so that the receiving portion 150 moves away from the receiving portion 540 along the lateral direction XX (as schematically indicated by arrow 52). Fig.16EAs shown, by keeping the first leg 811 and the second leg 812 in the first receiving recess 191 and the second receiving recess 192 and pulling the tool 800 away from the electrical connector 20 (as schematically indicated by arrow 53), the receiving portion 150 can be moved out of the receiving portion 540 along the lateral direction XX (as schematically indicated by arrow 54), thereby disengaging the electrical connector 10 from the electrical connector 20. In addition, the third leg 813 of the tool 800 can be used to engage with the base 401 of the latch member 400 to move the latch member 400 from the locking position to the pre-locking position. This configuration can facilitate the operation of the electrical connector 10 in a space-constrained environment to disengage the electrical connector 10 from the electrical connector 20.

[0271] The electrical connector 20' can be mated and unmated with the electrical connector 10 in a similar manner. For the sake of brevity, the details of these identical parts are not repeated here.

[0272] Having thus described several embodiments, it will be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art.

[0273] It should be understood that the terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh" and "eighth" are only used to distinguish one element, component or part from another element, component or part, but these elements, components and parts should not be limited by such terms.

[0274] The present application has been described in detail above in conjunction with specific embodiments. Obviously, the above description and the embodiments shown in the accompanying drawings should be understood as exemplary and do not constitute a limitation to the present application. For those skilled in the art, various modifications or changes can be made to the present application without departing from the spirit of the present application, and these modifications or changes do not depart from the scope of the present application.
