Description

Technical Field

[0001] The present disclosure generally relates to the field of connector technology, and in particular, to an electrical connector such as a cable connector, a board connector adapted to the electrical connector, and an electronic system including the board connector. The electrical connector is particularly suitable for harsh environments with strong vibrations such as vehicles, and more specifically, the electrical connector is suitable for new energy vehicles. Background Art

[0002] Electrical connectors are used in many electronic systems. Often, it is easier and more cost-effective to manufacture an electronic system as separate electronic components that can be connected together using electrical connectors. Electrical connectors can be used to interconnect components so that the components can work together as part of an electronic system. For example, electrical connectors can be mounted on circuit boards within two components that are connected by mating with the electrical connectors. In other electronic systems, it may be impractical to connect two circuit boards by directly mating the electrical connectors on the circuit boards. For example, when assembling the electronic system, the circuit boards may be spaced so far apart that the electrical connectors mounted in the circuit boards cannot be directly connected.

[0003] In some electronic systems, connections between components can be made via cables. The cables can be terminated with connectors that mate with connectors mounted on a circuit board. In this way, connections between components can be made by inserting an electrical connector that is part of a cable assembly into an electrical connector mounted on a circuit board. In other electronic system architectures, an electrical connector that terminates a cable can mate with another electrical connector that terminates another cable.

[0004] A modern automobile is an example of an electronic system in which components are connected by cables. For example, an automobile includes an electronic control unit (ECU) that is used to control various vehicle systems, such as the engine, transmission (TCU), safety system, emission control, lighting, advanced driver assistance system (ADAS), entertainment system, navigation system, and camera. The ECU can be manufactured as separate components and connected through one or more vehicle networks formed with cables arranged between these components. In order to simplify the manufacture of the automobile, these components can be manufactured separately and then connected by cables terminated with electrical connectors that can be connected to matching electrical connectors that terminate other cables or are attached to circuit boards within these components.

[0084] In the following description, a large amount of details are provided so that the present disclosure can be thoroughly understood. However, it will be appreciated by those skilled in the art that the following description only exemplarily illustrates a preferred embodiment of the present disclosure, and the present disclosure can be implemented without one or more such details. In addition, in order to avoid confusion with the present disclosure, some technical features well known in the art are not described in detail.

[0085] The Netbridge connector is an Ethernet connector in the automotive field. It is designed to support high-speed Ethernet communications and is used to connect high-speed data between electronic control units (ECUs), sensors and other devices inside the car. Netbridge connectors are generally focused on supporting high-speed data transmission. The inventors are aware of and understand that with the miniaturization of electronic devices such as circuit boards, there is not enough space on the electronic devices to connect the desired number of electrical connectors. Based on this, the inventors are aware of and understand a solution for a hybrid electrical connector that can be assembled economically. Using this hybrid electrical connector can ensure good signal integrity for high-speed data signals in harsh environments such as vehicles, while transmitting low-speed data signals and / or providing reliable power supply.

[0086] In some embodiments, the electrical connector may include one or more first signal lead assemblies and a plurality of first terminals. The plurality of first terminals are used to transmit power signals and / or low-speed data signals. The plurality of first terminals may be arranged in an array. For example, ten first terminals are arranged in two rows and five columns to form a 2×5 array. Exemplarily, eight first terminals are arranged in two rows and four columns to form a 2×4 array. As another example, six first terminals may be arranged in two rows and three columns to form a 2×3 array. Each first terminal may include a mating contact portion and a mounting portion, the mating contact portion being configured to mate with a terminal on an adapting electrical connector such as one that can be mounted to a circuit board, and the mounting portion being configured to be connectable to a conductive element such as a cable. Optionally, among these first terminals, a portion of the first terminals is configured to transmit a power signal, and another portion of the first terminals is configured to transmit a low-speed data signal. Optionally, all of the first terminals may be configured to transmit a power signal, or all of the first terminals may be configured to transmit a low-speed data signal. One or more first signal lead assemblies are used to transmit high-speed data signals. The plurality of signal lead assemblies may be arranged in an array. For example, two first signal lead assemblies can be arranged side by side and form a 1×2 array. Each first signal lead assembly can include one or more first signal terminals held by an insulating member. Each first signal terminal can include a mating contact portion and a mounting portion, the mating contact portion being configured to mate with a signal lead assembly on an adapter electrical connector such as one that can be mounted to a circuit board, and the mounting portion being configured to be connectable to a conductive element such as a cable. In some embodiments, each signal lead assembly can be configured to carry a signal, either as a single-ended signal or as a differential signal. In the exemplary embodiments described below, each signal lead assembly has a pair of first signal terminals suitable for carrying differential signals.

[0087] In some embodiments, the electrical connector may have a first insulating housing. The first insulating housing has a first mounting cavity and a plurality of first mounting channels. The first insulating housing has a first mating portion and a first mounting portion. The first signal lead assembly can be mounted from the first mounting portion to the first mounting cavity. Each of the plurality of first terminals can be mounted from the first mounting portion to a corresponding first mounting channel. The first insulating housing of this structure allows the first signal lead assembly and the first terminal to be economically assembled thereon.

[0088] Electrical connectors on cars usually operate in harsh environments such as high speed and vibration. The vibration generated during the car's speeding may cause the electrical connector to disconnect and stop working completely. Even if the vibration does not completely hinder the operation of the electrical connector, it will form electrical noise that interferes with the operation of electronic devices connected to the electronic system including the electrical connector. For example, the noise may be caused by the relative movement of components within the electrical connector, which may change the electrical performance of the electrical connector and / or fail to provide a reliable power signal. In some embodiments, a terminal locking component is provided on the first insulating housing to limit the movement of the first terminal in the mating direction with the adapter electrical connector.

[0089] The inventors also realize and understand that by arranging multiple terminals in two rows, it is more conducive to keep them in the desired position by a terminal locking component. Exemplarily, each row can be parallel to a first lateral direction perpendicular to the mating direction. The terminal locking component can be U-shaped, and the terminal locking component can have two locking legs. Each locking leg can lock a row of terminals. For example, a notch or a protrusion can be provided on the first terminal, and the locking leg can be inserted into the notch or blocked behind the protrusion (i.e., the side of the first mounting portion facing the first insulating housing) along the first lateral direction, thereby preventing multiple terminals from exiting the first insulating housing from the first mounting portion. Exemplarily, a locking strip can be provided on the inner surface of the locking leg facing the inside of the first insulating housing, and the locking strip is used to block multiple terminals from exiting the first insulating housing. Exemplarily, the locking strip can be located inside the first insulating housing. A locking groove can be provided on the first insulating housing, and the locking leg can be embedded in the locking groove. The locking strip can enter the inside of the first insulating housing through the locking groove to limit the multiple first terminals. For example, the locking strip may protrude from the locking leg along the first lateral direction, for example, the locking leg may span a portion of the first terminals in the corresponding row along the first lateral direction, and the locking strip may span all the first terminals in the corresponding row along the first lateral direction. Thus, the opening on the first insulating housing may be relatively short, which is beneficial to maintaining the mechanical strength of the first insulating housing.

[0090] In some embodiments, the terminal locking component can be fixed to the first insulating housing by a locking leg. For example, one side of the terminal locking component and the corresponding side of the locking groove can be matched by a slide bar and a slide groove, and the other side of the terminal locking component and the corresponding side of the locking groove can be matched by a locking hook and a notch.

[0091] In some embodiments, the first insulating housing may be provided with a notch, and each first terminal may be provided with a terminal protrusion, which may engage with the notch to prevent the first terminal from exiting the first insulating housing. The terminal protrusion and the terminal locking component mentioned above may exist separately or simultaneously.

[0092] This electrical connector can be used together with the adapter electrical connector to interconnect two electronic devices in the electronic system. In some embodiments, the electronic system may include a board connector and a cable connector. The board connector is installed on a circuit board, and the cable of the cable connector is connected to an electronic device that is a certain distance from the circuit board. By connecting the board connector and the cable connector to each other, the electronic device can be interconnected with the circuit board. The electrical connector provided by the embodiment of the present disclosure can be used as a cable connector, and the adapter electrical connector provided by the embodiment of the present disclosure can be used as a board connector.

[0093] In addition, the inventors also realized and understood that the adapter electrical connector may have a second insulating shell. The second insulating shell may include a second mating portion and a second mounting portion. The second mating portion can be mated and connected with any of the aforementioned electrical connectors. A single mating opening is provided on the second mating portion. The aforementioned electrical connector may be configured as a plug connector, and the adapter electrical connector may be configured as a socket connector. The second mating portion of the plug connector may be inserted into the mating opening. The second mounting portion may include a second mounting cavity aligned with the mating opening and a plurality of second mounting channels. Second terminals may be mounted in a one-to-one correspondence in the plurality of second mounting channels. A second signal lead assembly may be mounted in the second mounting cavity.

[0094] In some embodiments, an electronic system is also provided. The electronic system may include a panel and a board connector. The panel is provided with a mounting opening. The board connector is fixed to the panel by a fastener. The board connector may include a second insulating housing, and a plurality of second terminals and a second signal lead assembly mounted in the second insulating housing. The second mating contact portion of the second insulating housing extends to the outside of the panel through the mounting opening. Exemplarily, the outer side of the second insulating housing may be provided with a flange protruding in a lateral direction, and the flange may abut against the inner surface of the panel. Thus, the position of the board connector relative to the panel may be limited. Then the board connector is connected to the panel by a fastener. The fastener may pass through the panel from the outside of the panel and be connected to the second insulating housing. Only a through hole corresponding to the fastener needs to be machined on the panel. Exemplarily, a board seal may be provided between the flange and the inner surface of the panel. Thus, the portion of the electrical connector located outside the panel may be reduced, thereby ensuring the neatness of the appearance. Exemplarily, the board seal is also configured to surround the fastening hole for mounting the fastener, so that the board seal may simultaneously seal around the mounting opening and the fastening hole to form a seal. The panel may be a part of a housing that encapsulates a circuit board connected to the board connector. The board seal may prevent foreign objects from entering the housing. Moreover, the installation opening and the fastening hole share the same seal, which may save space, reduce the number of parts, and reduce the difficulty of assembly. In addition, the board seal may be provided with a head, and the second insulating housing may be provided with a recessed portion, and the head may be installed in the recessed portion, so that the board seal will not fall off from the second insulating housing.

[0095] Figure 1-2 900, for example, for use in an automobile, is shown for interconnecting a plurality of electronic devices in the electronic system 900. Figure 1-2 As shown, the electronic system 900 may include the electrical connector 100 and the mating electrical connector 600. The mating electrical connector 600 may be mounted on a circuit board 920. Figure 3-4The schematic diagram of the electronic system 900 after removing the circuit board 920 is shown. The electrical connector 100 can be connected with the adapter electrical connector 600. The electrical connector 100 can be a cable connector. The electrical connector 100 can be electrically connected to an electronic device such as another circuit board through a cable. The electrical connector 100 and the adapter electrical connector 600 can provide interconnection between the electronic device and the circuit board 920. The electronic device and the circuit board 920 can have a certain distance. Typically, the adapter electrical connector 600 is usually installed on the target object as a socket electrical connector, so the adapter electrical connector 600 can be directly installed on the circuit board 920. The electrical connector 100 can be connected with the socket electrical connector as a plug electrical connector. In other embodiments not shown, the electrical connector 100 can be directly installed on the circuit board, and the adapter electrical connector 600 is configured as a cable connector to interconnect a farther electronic device with the circuit board. Or, optionally, the electrical connector 100 and the adapter electrical connector 600 are both connected to respective electronic devices such as circuit boards through cables. Preferably, one of the electrical connector 100 and the mating electrical connector 600 can be fixed on the target object. In a harsh environment such as that presented by an automobile, the electronic system 900 needs to provide high data rate transmission while being subjected to vibration.

[0096] Figure 5-11 The structure of the electrical connector 100 according to an embodiment of the present disclosure is shown from different angles. Figure 7-11 Relative to Figure 5-6 The outer shell 500 is removed. For clarity and simplicity of description, a mating direction XX, a first lateral direction YY, and a second lateral direction ZZ are defined. Any two of the mating direction XX, the first lateral direction YY, and the second lateral direction ZZ may be perpendicular to each other.

[0097] like Figure 5-11 As shown, the electrical connector 100 may include a first insulating housing 200. The first insulating housing 200 and the second insulating housing 700 to be described later may be insulating. The first insulating housing 200 and / or the second insulating housing 700 may be molded from an insulating material such as plastic. The plastic may include but is not limited to liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylene oxide (PPO) or polypropylene (PP), or other materials may also be used. In some cases, the plastic may be a thermosetting plastic. In some cases, the insulating plastic may include an insulating material such as glass fiber reinforced. The first insulating housing 200 and the second insulating housing 700 may generally be an integral piece, respectively. Figure 12-14The structure of a separate first insulating housing 200 is shown. As shown in the figure, the first insulating housing 200 may have a first mating portion 201 and a first mounting portion 202. The first mating portion 201 may be used to mate with the adapting electrical connector 600 along the mating direction XX. The first mounting portion 202 may face away from the adapting electrical connector 600. A plurality of first mounting channels 211 and a first mounting cavity 212 may be provided in the first insulating housing 200. The first mounting channel 211 and the first mounting cavity 212 may extend from the first mating portion 201 to the first mounting portion 202, respectively. In the illustrated embodiment, the first mating portion 201 and the first mounting portion 202 both extend along the mating direction XX and are located at both ends of the first insulating housing 200. In this case, the first mounting channel 211 and the first mounting cavity 212 may both extend along the mating direction XX. In other embodiments not shown, the first mating portion 201 and the first mounting portion 202 may be perpendicular to each other, and the first mounting portion 202 may extend along a lateral direction (e.g., a first lateral direction YY or a second lateral direction ZZ) perpendicular to the mating direction XX. In this case, the first installation channel 211 and the first installation cavity 212 may have a bent structure. Of course, the first matching portion 201 and the first installation portion 202 may also have other angles.

[0098] The electrical connector 100 may further include a plurality of first terminals 310, such as Fig.11 As shown. The number of the first terminals 310 may be, for example, two, three or more. Preferably, the first terminals 310 may be an even number, such as two, four, six or more. In the illustrated embodiment, there may be six first terminals 310. The six first terminals 310 may be arranged in two rows parallel to the first lateral direction YY and three columns parallel to the second lateral direction ZZ, and form a 2×3 array. Specifically, each row may include three first terminals 310 arranged along the first lateral direction YY. Two rows of first terminals 310 may be spaced apart along the second lateral direction ZZ. In Fig.26 In the electronic system 900' shown, it can be seen from the number of the first cable 350 of the electrical connector 100' and the terminal insertion through holes 921 on the circuit board 920 that there can be ten first terminals thereon. The ten first terminals can form a 2×5 array. Similarly, Fig. 27 In the illustrated electronic system 900 ″, the six first terminals of the electrical connector 100 ″ may form a 2×3 array. Similarly, Fig.28In the illustrated electronic system 900'', the eight first terminals of the electrical connector 100'' can form a 2×4 array. Regardless of the number of the first terminals 310, the first terminals 310 are arranged in a one-to-one correspondence with the first mounting channels 211, so that each first terminal 310 can be installed in the corresponding first mounting channel 211. In this way, the plurality of first terminals 310 can be assembled efficiently and economically, and adjacent first terminals 310 can be spaced apart to ensure that the plurality of first terminals 310 can be insulated from each other.

[0099] Each first terminal 310 can be used to transmit a low-speed data signal and / or a power signal. In the electrical connector 100, all of the first terminals 310 can be used to transmit a low-speed data signal; or all of the first terminals 310 can be used to transmit a power signal; or a portion of the first terminals 310 can be used to transmit a low-speed data signal, and another portion of the first terminals 310 can be used to transmit a power signal. When the first terminal 310 is used to transmit a power signal, it can provide power supply. The low-speed data signal may include auxiliary information and / or a control signal. The low-speed data signal is usually not the main data, but an additional signal responsible for supporting and managing data transmission. The control signal may include one or more of a control command, status information, error detection and correction, etc. The auxiliary information may include one or more of a checksum, flow control, and clock synchronization, etc. The transmission of auxiliary information helps to ensure the integrity, reliability, and synchronization of the data. Optionally, the first terminal 310 can also be used to manage various configurations and functions of the device. For example, the electronic system 900 can send a management command to the electronic device through the first terminal 310 to modify configuration parameters, query device status, identify device information, etc. Thus, the first terminal 310 and the signal transmission path connected thereto can be adaptively adopted to only support low-speed data signals and / or structures, thereby reducing manufacturing costs. In some embodiments, the first terminal 310 can transmit low-frequency signals (e.g., 66MHz), signals with lower data rates (e.g., less than 100Mb / s), logic control signals, etc.

[0100] For example, the first terminals 310 can be installed into the first installation channels 211 corresponding to the first installation portions 202 from one side thereof. Fig.17As shown, each first terminal 310 may include a first terminal mating contact portion 312 and a first terminal mounting portion 315. The first terminal mating contact portion 312 and the first terminal mounting portion 315 may be arranged at both ends of the first terminal 310. When each first terminal 310 is installed in place in its respective first mounting channel 211, the first terminal mating contact portion 312 may abut against the first mating portion 201 of the first insulating shell 200 to improve assembly efficiency. The first terminal mating contact portion 312 is used to electrically contact the corresponding second terminal 810 (which will be described in detail below) on the adapter electrical connector 600. In this way, the electrical connector 100 and the adapter electrical connector 600 can be electrically connected to transmit low-speed data signals or power signals. The first terminal mounting portion 315 is used to connect the first cable 350. In order to reduce costs and ensure the reliability of the connection, a portion of the first cable 350 may extend into the first mounting channel 211, such as Fig.11 As shown. In general, the first terminal 310 is straight as a whole. In the illustrated embodiment, when the first mounting channel 211 extends along the mating direction XX, the portion of the first cable 350 located in the first mounting channel 211 is also straight. However, in an embodiment where the first mating portion and the first mounting portion are angled so that the first mounting channel is curved, the portion of the first cable located in the first mounting channel can be curved to adapt to the shape of the first mounting channel.

[0101] Return to see Fig.17, the first cable 350 may include a conductive core 351 and an insulating layer 352 sheathed on the conductive core 351. The insulating layer 352 on the end of the first cable 350 that needs to be terminated with the first terminal 310 is removed to expose a section of the conductive core 351 inside. The exposed conductive core 351 and a portion of the insulating layer 352 adjacent to the exposed conductive core 351 may be placed on the first terminal mounting portion 315. A first pressing claw 315a may be provided on the first terminal mounting portion 315. The shape of the first pressing claw 315A may conform to the IPC620 standard formulated by the International Electronic Components Industry Association. The first pressing claw 315a may be pressed onto the conductive core 351 of the first cable 350. Generally, the first terminal 310 may be made of a metal material, and the metal may have good plasticity, so that the first pressing claw 315a may be easily pressed onto the conductive core 351 and may also be in electrical contact with the conductive core 351. After the first pressing claw 315a is pressed on the conductive inner core 351, it will be higher than the conductive inner core 351. Therefore, the first pressing claw 315a can be spaced apart from the first terminal mating contact portion 312 to form a terminal locking groove 314 (the terminal locking groove 314 will be described in more detail later). In order to firmly fix the conductive inner core 351, the first pressing claw 315a can be arranged in pairs. A pair of first pressing claws 315a can not overlap each other after being pressed on the conductive inner core 351. In addition, by adjusting the size of the first pressing claw 315a, a desired contact area can also be formed between the first pressing claw 315a and the conductive inner core 351, thereby achieving impedance matching.

[0102] Optionally, a second pressing claw 315b may also be provided on the first terminal mounting portion 315. The second pressing claw 315b may be pressed onto the folded insulating layer 352. Of course, if the stripped insulating layer 352 is removed, it may be directly pressed onto the insulating layer 352 of a first cable 350 adjacent to the rear. The second pressing claw 315b may be one or more. When there are multiple second pressing claws 315b, optionally, the multiple second pressing claws 315b may also be staggered along the mating direction XX, so that they may not overlap each other when pressed onto the insulating layer 352, to avoid causing the size at that location to be too large. Exemplarily, the shapes of the multiple second pressing claws 315b may be complementary, so that they may press onto most of the insulating layer 252, thereby ensuring the firmness of the connection. Along the mating direction XX, the second crimping claw 315b can be spaced apart from the first crimping claw 315a by a certain distance. This distance can ensure that once a deviation occurs in processing the end of the first cable 350, causing the conductive core 351 to protrude too much or too little relative to the insulating layer 352, the first crimping claw 315a can still be crimped only on the conductive core 351, and the second crimping claw 315b can still be crimped only on the insulating layer 252, so as to avoid affecting the electrical performance of the electrical connector 100.

[0103] Exemplarily, the first terminal mating contact portion 312 may include a conductive sleeve 312a for receiving the corresponding second terminal 810 on the adapter electrical connector 600. The conductive sleeve 312a may be provided with a first elastic sheet 312b and a second elastic sheet 312c. The first elastic sheet 312b and the second elastic sheet 312c are both cantilevered with one end free, and the free ends of the two overlap each other and bend toward the conductive sleeve 312a to increase the elasticity of the overlapping portion. When the corresponding second terminal 810 on the adapter electrical connector 600 is inserted into the conductive sleeve 312a, the bent portion of the first elastic sheet 312b and the second elastic sheet 312c abuts against the second terminal 810. Thus, reliable electrical contact between the first terminal 310 and the second terminal 810 can be ensured, and the second terminal 810 can be firmly held in the first terminal 310. Exemplarily, each first terminal 310 can be formed by bending a piece of metal sheet. The first elastic sheet 312b and the second elastic sheet 312c and the first pressing claw 315a and the second pressing claw 315b can be formed by punching or cutting the edge of the metal sheet and then bending it. The first elastic sheet 312b and the second elastic sheet 312c can be located on the same side of the metal sheet.

[0104] A terminal protrusion 312d may be provided on the other side of the metal sheet. For example, the terminal protrusion 312d may be formed by processing a cantilever on the metal sheet and bending it outward, and the free end of the cantilever is the terminal protrusion 312d. The terminal protrusion 312d may be engaged with a locking feature such as the notch 220 on the first insulating housing 200, such as Fig.11 As shown, the first terminal 310 is limited to prevent the first terminal 310 from exiting the first insulating housing 200. Along the second lateral direction ZZ, the conductive sleeve 312a has a side facing the outside of the first insulating housing 200, for example Fig.17The upper side of the first terminal 310 above and the lower side of the first terminal 310 below. The terminal protrusion 312d can be arranged on this side. When the first terminal 310 is inserted into the corresponding first mounting channel 211 from one side of the first mounting portion 202, the cantilever can be elastic to ensure that the terminal protrusion 312d smoothly enters the first mounting channel 211, and pops out and engages with the locking feature when moving to the locking feature. In the direction opposite to the installation direction (i.e., in the direction toward the first mounting portion 202), the terminal protrusion 312d abuts against the side wall of the locking feature, thereby preventing the first terminal 310 from detaching from the first insulating housing 200 from one side of the first mounting portion 202. In other embodiments not shown, the terminal protrusion 312d can also have other structures, for example, it can include a strip-shaped component cut out from the first terminal 310, the middle of the strip-shaped component protrudes toward the first insulating housing 200, but both ends of the strip-shaped component are connected to the first terminal 310. Such an arrangement can also ensure that the terminal protrusion is elastic and can be engaged with the locking feature.

[0105] For example, Figure 6-8 As shown in Figures 11-13, there can be multiple notches 220. Multiple notches 220 can be arranged in one-to-one correspondence with multiple first terminals 310. By arranging multiple first terminals 310 into two rows, each row of first terminals 310 has a side that can be adjacent to the first insulating housing 200, so that notches 220 can be arranged on the side opposite to each other along the second lateral direction ZZ of the first insulating housing 200. A row of notches 220 can be arranged on each side. Two rows of notches 220 can be engaged with adjacent rows of first terminals 310, respectively. In the illustrated embodiment, the notch 220 passes through from the inner surface of the first insulating housing 200 to the outer surface. In other embodiments not shown, the notch 220 can be a blind hole arranged on the inner surface of the first insulating housing 200. Typically, the first insulating housing 200 is a molded part. Compared with a blind hole, setting the notch 220 to be through is more convenient for processing. Furthermore, it is easier to detect from the appearance whether the terminal protrusion 312d has been engaged in the notch 220, so as to determine whether the assembly of the electrical connector 100 meets the requirements. Furthermore, the notch 220 can also be used for heat dissipation to reduce the temperature of the first terminal 310. In addition, each row of first terminals 310 can share the same notch. In this case, the notch is generally in the shape of a long groove extending in the direction of the row. Providing a separate notch 220 for each first terminal 310 can avoid a significant impact on the mechanical structure of the first insulating shell 200. Moreover, by reasonably setting the size of the notch 220 along the first lateral direction YY, it is adapted to the size of the terminal protrusion 312d in the first lateral direction YY. The notch 220 can also limit the corresponding first terminal 310 along the first lateral direction YY. For example, as Fig.11 As shown, the position of the notch 220 may correspond to the position of the first terminal mating contact portion 312. As mentioned above, it is more convenient to process the terminal protrusion 312d mating with the notch 220 at the first terminal mating contact portion 312.

[0106] In the above embodiment, a locking feature such as a notch 220 is used to block the terminal protrusion 312d in the direction toward the first mounting portion 202. Optionally, other locking features may be provided to limit the first terminal 310 in the direction toward the first mating portion 201. Alternatively, the movement of the plurality of first terminals 310 is limited by the same locking feature along the mating direction XX (including along the direction toward the first mounting portion 202 and along the direction toward the first mating portion 201). Exemplarily, the first terminal mating contact portion 312 may abut against the first mating portion 201 of the first insulating housing 200. The locking feature may be configured to limit the plurality of first terminals 310 in the direction toward the first mounting portion 202. In this way, after the first terminal 310 is installed from one side of the first mounting portion 202 into the first mounting channel 211 corresponding to each other, the first mating portion 201 and the locking feature may clamp the portion of the first terminal 310 located therebetween, thereby limiting the first terminal 310 in the mating direction XX.

[0107] Alternatively or additionally, such as Figure 6-9 As shown in Figures 16a-16b, the locking feature may further include a terminal locking component (TPA) 420. The terminal locking component 420 may be installed to the first insulating housing 200 along the first lateral direction YY. After the plurality of first terminals 310 are installed in the first mounting channels 211 corresponding to each other, the terminal locking component 420 may be installed to the first insulating housing 200 along the first lateral direction YY. Each first terminal 310 may be provided with a terminal locking adapter that cooperates with the terminal locking component 420, for example Fig.17 The terminal locking groove 314 in the first terminal 310. On the first terminal 310, the first terminal mating contact portion 312 and the first terminal mounting portion 315 are arranged at intervals to form the terminal locking groove 314. In other embodiments not shown, the terminal locking adapter may also have other structures, for example, may include any suitable protrusions or grooves. Exemplarily, the terminal locking component 420 can abut against the first terminal mating contact portion 312 to limit the plurality of first terminals 310 along the direction toward the first mounting portion 202. Of course, if necessary, the terminal locking component 420 can also abut against the first terminal mounting portion 315 to limit the plurality of first terminals 310 along the direction toward the first mating portion 201.

[0108] For example, Figure 6-9As shown in Figures 16a-16b, in an embodiment where a plurality of first terminals 310 are arranged in two rows along the second lateral direction ZZ, the terminal locking component 420 may include a first locking leg 431 and a second locking leg 432. A connecting portion 433 may be provided between the first locking leg 431 and the second locking leg 432 to achieve mutual connection. In this way, the terminal locking component 420 may be generally U-shaped. The first locking leg 431 and the second locking leg 432 may respectively lock one of the two rows of first terminals 310. Thus, a single terminal locking component 420 may be used to limit the two rows of first terminals 310 at the same time. In this way, the number of components may be reduced. Exemplarily, the first locking leg 431 and the second locking leg 432 may be split parts, which may be respectively mounted on the first insulating housing 200.

[0109] For example, Fig.12 As shown, the first insulating shell 200 may be provided with a locking groove 280 extending along the first lateral direction YY. The first mating portion 201 of the first insulating shell 200 has a first side surface 201a and a second side surface 201b opposite to each other along the second lateral direction ZZ. Each of the first side surface 201a and the second side surface 201b is provided with an inwardly recessed locking groove 280. The two locking grooves 280 can be respectively installed with a first locking leg 431 and a second locking leg 432. For each locking groove 280, the locking groove 280 may have a first locking groove side wall 281 and a second locking groove side wall 282 that are arranged opposite to each other along the mating direction XX. A second slide groove 283 may be provided on the first locking groove side wall 281. A notch 284 may be provided on the second locking groove side wall 282. The opening of the notch 284 may face the first locking groove side wall 281. As shown in FIG. Fig.16a and Fig.16b As shown, the terminal locking component 420 may have a first side 421 and a second side 422 that are arranged opposite to each other along the mating direction XX. The first side 421 may be provided with a slide bar 440. The second side 422 may be provided with a locking hook 450. During the process of installing the terminal locking component 420 to the first insulating housing 200 along the first lateral direction YY, the slide bar 440 may be inserted into the second slide groove 283. In this way, the second slide groove 283 may play a better guiding role for the terminal locking component 420. When the terminal locking component 420 is installed in place, the locking hook 450 is engaged with the notch 284. In this way, the notch 284 may play a limiting role, thereby preventing the terminal locking component 420 from being separated from the first insulating housing 200.

[0110] For example, Fig.16a and Fig.16bAs shown, the terminal locking component 420 may be provided with a slit 423 extending along the first lateral direction YY. The slit 423 may pass through from the inner surface to the outer surface of the terminal locking component 420. The inner surface and the outer surface are arranged opposite to each other along the second lateral direction ZZ, and the inner surface and the outer surface face the inside and the outside of the first insulating shell 200 respectively. The slit 423 is arranged close to the second side 422, so that the distance from the slit 423 to the first side 421 is greater than the distance to the second side 422. Thus, an elastic beam 424 is formed between the slit 423 and the second side 422. The locking hook 450 is arranged at a position corresponding to the middle of the slit 423. Thus, in the process of installing the terminal locking component 420 to the locking groove 280, with the help of the elasticity of the elastic beam 424, the locking hook 450 can smoothly slide into the notch 284 on the side of the locking groove 280. Exemplarily, in combination with reference to Figure 6-9 , 16a - 16b and 17 , the locking groove 280 may correspond to the position of the terminal locking groove 314 on the first terminal 310 .

[0111] Exemplarily, the terminal locking part 420 may include a locking body 460. In the case where the terminal locking part 420 includes a first locking leg 431 and a second locking leg 432 connected to each other in a U shape, the locking body 460 is U-shaped. The locking body 460 may have an inner surface 461 facing the inside of the first insulating housing 200 and an outer surface 462 facing the inside of the first insulating housing 200. Exemplarily, the slit 423 may be provided on the locking body 460 and pass through from the inner surface 461 to the outer surface 462. The locking hook 450 is provided on the locking body 460. A locking strip 470 extending along the first lateral direction YY may be provided on the inner surface 461. Along the mating direction XX, the locking strip 470 may be closer to the first side 421 of the terminal locking part 420 to make way for the slit 423. When the terminal locking member 420 is installed in the locking groove 280, the locking strip 470 can be embedded in the terminal locking groove 314 of each first terminal 310. The locking strip 470 can block the plurality of first terminals 310 in the direction toward the first mounting portion 202. There can be two locking strips 470, which are respectively arranged corresponding to the two rows of first terminals 310. The two locking strips 470 are respectively located on the two legs of the U-shaped locking body 460 to form a first locking leg 431 and a second locking leg 432, respectively.

[0112] For example, see Figure 11-12 16a-16b, the locking groove 280 for installing the terminal locking member 420 can span across the plurality of first terminals 310 in each row along the first lateral direction YY. The locking body 460 can be completely accommodated in the locking groove 280 and span across the plurality of first terminals 310 in each row. Fig.16a and Fig.16bAs shown, the locking strip 470 can protrude from the locking body 460 along the first lateral direction YY, so that the locking strip 470 has a protruding end 471. The protruding end 471 can extend into the inner space 204 of the first insulating housing 200, as shown in FIG. Fig.10 As shown. In addition, the first insulating housing 200 is also provided with a process hole 205 connected to the internal space 204. The process hole 205 can extend along the mating direction XX to the end surface of the first mounting portion 202. Optionally, the locking body 460 can span a portion of the plurality of first terminals 310 in each row along the first lateral direction YY, and the locking strip 470 can span all the first terminals 310 in each row. In this way, the length of the locking groove 280 along the first lateral direction YY is shortened, and the mechanical strength of the first insulating housing 200 can be enhanced.

[0113] For example, Fig.16a and Fig.16b As shown, at the first side 421 of the terminal locking component 420, the locking strip 470 can be flush with the locking body 460, thereby increasing the thickness of the terminal locking component 420 near the first side 421. Therefore, the first side 421 can have a sufficient thickness to set a sufficiently wide slide bar 440, so that the slide bar 440 has a greater mechanical strength. For example, as Fig.16a and Fig.16b As shown, the slide bar 440 can be flush with the inner surface 472 of the locking bar 470. The slide bar 440 can be spaced apart from the outer surface 462 of the locking body 460. The slide bar 440 extending to the inner surface 472 of the locking bar 470 can further increase the width of the slide bar 440, and can act as a part of the locking bar 470 to lock the first terminal 310. In addition, the slide bar 440 can be spaced apart from the outer surface 462 of the locking body 460 by a large distance, and the distance is adapted to the thickness of the first insulating housing 200, so that the first insulating housing 200 can be prevented from being thinned, and the first insulating housing 200 can be ensured to have a sufficiently large mechanical strength.

[0114] For example, Figure 4 and 7 As shown in FIG. 11 , the electrical connector 100 may further include a mating end seal 330. The mating end seal 330 may be disposed on an outer surface of the first mating portion 201 of the first insulating housing 200. The mating end seal 330 may surround the first mating portion 201 along a circumferential direction perpendicular to the mating direction XX. Specifically, as shown in FIG. Figure 12-14 As shown, an annular groove 290 may be provided on the outer surface of the first mating portion 201. The mating end seal 330 may be embedded in the annular groove 290. When the electrical connector 100 is connected to the mating electrical connector 600, as shown in FIG. Figure 4As shown, the mating end seal 330 can be clamped between the first mating portion 201 and the adapting electrical connector 600. Figure 19-21 , 22a, 22b and 23-24, the adapter electrical connector 600 may include a second insulating housing 700 and a plurality of second terminals 810. The second insulating housing 700 may include a second mating portion 710 and a second mounting portion 720. The second mating portion 710 may have a second mating end 711 and a second mounting end 712. The second mating end 711 and the second mounting end 712 may be arranged opposite to each other along the mating direction XX. A single mating opening 713 may be provided on the second mating portion 710. The mating opening 713 may extend from the second mating end 711 to the second mounting end 712. The second mounting portion 720 may be connected to the second mounting end 712. The second mounting portion 720 may have a plurality of second mounting channels 721. The plurality of second terminals 810 may be mounted in the second mounting channels 721 in a one-to-one correspondence. In this way, the plurality of second terminals 810 may be assembled economically and quickly with the second insulating housing 700, and it is ensured that the plurality of second terminals 810 may be insulated from each other.

[0115] The second mounting channel 721 can be aligned with the mating opening 713. The second terminals 810 can correspond to the first terminals 310 one by one for transmission. Each second terminal 810 can include a second terminal mating contact portion 811 (eg, Fig.19 as shown) and the second terminal mounting portion 812 (as shown Fig. 20 ). The second terminal mating contact portion 811 can extend into the mating opening 713. When the electrical connector 100 is connected to the mating electrical connector 600, the first mating portion 201 of the electrical connector 100 can be inserted into the mating opening 713, and the second terminal mating contact portion 811 is inserted into the corresponding first mounting channel 211 of the first mating portion 201 and electrically contacts the corresponding first terminal 310, so that the electrical connector 100 can be electrically connected to the mating electrical connector 600. Exemplarily, the mating end seal 330 can be clamped between the outer side wall of the first mating portion 201 and the inner side wall of the mating opening 713, as shown. Figure 4 As shown. In this way, dust and other dirt are not easy to enter the first mating portion 201 and the mating opening 713 to affect the electrical connection between the first mating portion 201 and the second mating end 711, which plays a role in waterproofing and dustproofing, thereby ensuring the reliability of the electrical connector 100 and the matching electrical connector 600. In addition, the mating end seal 330 is usually squeezed and deformed between the outer side wall of the first mating portion 201 and the inner side wall of the mating opening 713, so it can play a shock absorbing role.

[0116] The second terminal mounting portion 812 may extend beyond the second mounting portion 720, such as Fig. 20 As shown. In this way, the second terminal mounting portion 812 can be mounted to the circuit board 920 (see Figure 1 ), so as to realize the circuit electrical connection with the circuit board 920. According to different installation technologies, the second terminal installation portion 812 may include a through-hole pin, an SMT end or a press-fit pin, etc. Optionally, a terminal insertion through hole 921 may be provided on the circuit board 920, see Fig.22a . The pattern in which these terminal insertion through holes 921 are arranged can correspond to the pattern in which the second terminal mounting portions 812 on the adapter electrical connector 600 to be connected are arranged. Optionally, the side walls of each terminal insertion through hole 921 can be plated with a metal conductive layer. The second terminal mounting portion 812 is inserted into the corresponding terminal insertion through hole 921 and can be in electrical contact with the metal conductive layer. The metal conductive layers of these terminal insertion through holes 921 can be electrically connected to different conductive traces in the circuit board 920 to form a desired circuit. In this way, the adapter electrical connector 600 and the circuit board 920 are electrically connected to transmit low-speed data signals and / or power signals.

[0117] For example, the second terminal 810 may be made of a conductive material such as metal. Each second terminal 810 may generally be an elongated integral piece. Depending on the type of the adapting electrical connector 600, the second terminal 810 may have different shapes. Figure 1-4 In the embodiments shown in , 19-21, 22a, 22b and 23-26, the adapting electrical connector 600 may be a vertical connector. The second terminal 810 may be substantially in the shape of a straight line extending along the mating direction XX. Fig. 27 and 28 In the illustrated embodiment, the adapting electrical connectors 600 ″ and 600 ′″ may be right-angle connectors. The second terminal 810 may be substantially L-shaped.

[0118] like Figure 6 and 9 As shown in Figure 10, the electrical connector 100 may further include a first signal lead assembly 320. The first signal lead assembly 320 may include an insulating layer disposed on the outside and one or more signal terminals disposed in the insulating layer. In the illustrated embodiment, two signal terminals may be disposed in the first signal lead assembly 320, thereby forming a differential signal terminal pair.

[0119] The number of the first signal lead assembly 320 can be any, including but not limited to one, two or more. Figure 1-21 In the embodiments shown in 22a, 22b, 23-24, 26 and 27, the first signal lead assembly 320 may be one. Fig.28In the illustrated embodiment, it can be seen from the number of the second cable 360 ​​and the signal insertion through hole 922 on the circuit board 920 that there can be two first signal lead assemblies thereon. The two first signal lead assemblies can be arranged along the first lateral direction YY. The first signal lead assemblies can be installed in the first mounting cavity one by one. In this way, the first signal lead assemblies 320 can be quickly and economically assembled into the respective first mounting cavities 212. The first signal lead assemblies 320 can be installed into the respective corresponding first mounting cavities 212 from one side of the first mounting portion 202.

[0120] Each first signal lead assembly 320 can be used to transmit high-speed data signals. Exemplarily, the differential signal terminal pair within the first signal lead assembly 320 can be configured to transmit high data rate signals (e.g., signals with a data rate exceeding 25 Gb / s in the case of PAM4 encoding) or high-frequency signals (e.g., exceeding 56 or 112 Gb / s). The first signal lead assembly 320 directly transmits high-speed data, which is beneficial to maintaining signal integrity and has high data access speed and system response performance. The first signal lead assembly 320 can extend from the first mating portion 201 to the first mounting portion 202. Each first signal lead assembly 320 can include a first signal mating contact portion and a first signal mounting portion. The first signal mating contact portion and the first signal mounting portion can be arranged at both ends of the first signal lead assembly 320. The first signal mating contact portion can extend to the first mating portion 201. In this way, the second signal lead assembly 820 (which will be described in detail below) on the adapter electrical connector 600 can be electrically contacted with the corresponding first signal mating contact portion. In this way, the electrical connector 100 and the adapting electrical connector 600 can be electrically connected to transmit high-speed data signals. The first signal mounting portion can be electrically connected to the second cable 360 ​​to transmit high-speed data signals to the electronic device through the second cable 360.

[0121] In order to reduce costs and ensure connection reliability, a portion of the second cable 360 ​​may extend into the first installation cavity 212, such as Fig.10 As shown. Generally, the first signal lead assembly 320 is straight as a whole. In the illustrated embodiment, when the first mounting cavity 212 extends along the mating direction XX, the portion of the second cable 360 ​​located in the first mounting cavity 212 is also straight. However, in an embodiment where the first mating portion and the first mounting portion are angled so that the first mounting cavity is curved, the portion of the second cable located in the first mounting cavity can be curved to adapt to the shape of the first mounting cavity.

[0122] For example, Figure 8 and 11As shown, the electrical connector 100 may further include a cable terminal seal 340. The first cable 350 and the second cable 360 ​​may pass through the cable terminal seal 340. Specifically, the cable terminal seal 340 may be provided with a first channel 341 and a second channel 342. The first cables 350 may pass through the first channel 341 in a one-to-one correspondence. The second cables 360 may pass through the second channel 342 in a one-to-one correspondence. The cable terminal seal 340 may be installed in the first mounting portion 202 of the first insulating housing 200, for example, the cable terminal seal 340 may be compressed in the first mounting portion 202. The cable terminal seal 340 may form a seal in the first mounting portion 202. In this way, dirt such as dust is not easy to enter the first insulating housing 200 from the first mounting portion 202, thereby ensuring the reliability of the electrical connector 100.

[0123] like Figure 19-21 , 22a, 22b and 23-24, a second mounting cavity 722 may be provided on the second mounting portion 720 of the second insulating housing 700 of the adapting electrical connector 600. The second mounting cavity 722 may be aligned with the mating opening 713 on the second mating portion 710 of the second insulating housing 700. The adapting electrical connector 600 may further include a second signal lead assembly 820. The second signal lead assembly 820 may be mounted in the second mounting cavity 722 in a one-to-one correspondence. In this way, the second signal lead assembly 820 may be fixed relative to the respective second mounting cavity 722. The second signal lead assembly 820 may be mounted in the respective corresponding second mounting cavity 722 from the rear side of the second mounting portion 720.

[0124] The second signal lead assembly 820 may correspond to the first signal lead assembly 320 one by one. Each second signal lead assembly 820 may include a second signal mating contact portion and a second signal mounting portion. The second signal mating contact portion and the second signal mounting portion may be disposed at both ends of the second signal lead assembly 820. The second signal mating contact portion may extend into the mating opening 713 on the second mating portion 710. When the electrical connector 100 is connected to the adapting electrical connector 600, the first mating portion 201 of the electrical connector 100 may be inserted into the mating opening 713, and the second signal lead assembly 820 may be inserted into the corresponding first mounting cavity 212 of the first mating portion 201 and electrically contact the corresponding first signal lead assembly 320, so that the electrical connector 100 may be electrically connected to the adapting electrical connector 600. In this way, high-speed data signals may be transmitted between the electrical connector 100 and the adapting electrical connector 600. The second signal mounting portion of the second signal lead assembly 820 may extend outside the second mounting portion 720. Thus, the second signal mounting portion can be mounted to the circuit board 920 by using surface mounting technology (SMT) and / or through hole mounting technology (THT) and the like (see Figure 1), so as to realize the circuit electrical connection with the circuit board 920. According to different installation technologies, the second signal installation part may include a through-hole pin, an SMT end or a press-fit pin, etc. Optionally, a signal insertion through hole 922 may be provided on the circuit board 920, see Fig.22a . The pattern in which these signal plug-in through holes 922 are arranged may correspond to the pattern in which the second signal mounting portions on the adapter electrical connector 600 to be connected are arranged. Optionally, a metal conductive layer may be plated on the side walls of each signal plug-in through hole 922. The second signal mounting portion is inserted into the corresponding signal plug-in through hole 922 and may be in electrical contact with the metal conductive layer. The metal conductive layers of these signal plug-in through holes 922 may be electrically connected to different conductive traces in the circuit board 920 to form a desired circuit. In this way, the adapter electrical connector 600 and the circuit board 920 are electrically connected to transmit high-speed data signals.

[0125] For example, Fig.14 As shown, the first mating portion 201 has an asymmetric outer profile in a lateral plane perpendicular to the mating direction XX. In the illustrated embodiment, in the lateral plane, the outer profile of the first mating portion 201 is asymmetric about a center line parallel to the second lateral direction ZZ. Accordingly, the inner side wall of the mating opening 713 of the second mating portion 710 of the adapting electrical connector 600 has a structure adapted to the outer profile of the first mating portion 201, as shown in FIG. Figure 22b and Fig.23 With such arrangement, relevant personnel can identify the installation direction of the first matching portion 201 and the matching opening 713 of the adapting electrical connector 600 by naked eye observation or detector detection. Therefore, it can have a better foolproof effect.

[0126] For example, Fig.14 As shown, the first mating portion 201 may have a first vertex 260 and a second vertex 270. The first vertex 260 and the second vertex 270 may be arranged relative to each other along the first lateral direction YY. The outer surfaces of the first vertex 260 and the second vertex 270 may both be inclined surfaces. A convex ridge 261 extending along the mating direction XX may be arranged on the inclined surface corresponding to the first vertex 260. With such an arrangement, the foolproof structure of the first mating portion 201 is more obvious, so that it can be easily observed. In addition, the structure of the first insulating shell 200 is relatively simple and convenient for processing and manufacturing.

[0127] Adaptively, the second mating portion 710 of the adapting electrical connector 600 may have a structure adapted to the first mating portion 201. Specifically, as Fig.23As shown, the mating opening 713 of the second mating portion 710 may have a third vertex angle 750 and a fourth vertex angle 760. The third vertex angle 750 and the fourth vertex angle 760 may be arranged relatively to each other along the first lateral direction YY. The outer surfaces of the third vertex angle 750 and the fourth vertex angle 760 may both be inclined surfaces. A groove 751 extending along the mating direction XX may be provided on the inclined surface corresponding to the third vertex angle 750. In this arrangement, when the electrical connector 100 is connected to the adapter electrical connector 600, the first vertex angle 260 may abut against the third vertex angle 750, and the convex ridge 261 may be inserted into the groove 751. The second vertex angle 270 may abut against the fourth vertex angle 760.

[0128] like Figure 19-21 As shown, the electronic system 900 may further include a panel 910. The panel 910 may serve as a mounting base for the adapter electrical connector 600, for example, it may be a housing of an electronic device in which the electrical connector 100 and the adapter electrical connector 600 are interconnected. A mounting opening 911 may be provided on the panel 910. The adapter electrical connector 600 may be fixed to the panel 910 by means of fasteners 840. Specifically, the second insulating shell 700 may be fixed to the panel 910 by means of fasteners 840. The fasteners 840 include but are not limited to screws or rivets. The second mating portion 710 of the adapter electrical connector 600 may pass through the mounting opening 911, thereby extending to the outside of the panel 910. The second mounting portions 720 of the adapter electrical connector 600 may be located on the inner side of the panel 910, respectively. Depending on the type of the adapter electrical connector 600, the positional relationship between the panel 910 and the circuit board 920 may be different. Figure 19-21 and Fig.26 In the illustrated embodiment, the adapting electrical connectors 600 and 600' are vertical connectors, and the panel 910 and the circuit board 920 can be parallel to each other. Fig. 27 and 28 In the illustrated embodiment, the adapting electrical connectors 600 ″ and 600 ′″ are right-angle connectors, and in this case, the panel 910 and the circuit board 920 may be perpendicular to each other.

[0129] For example, Fig.21 , 22a, 22b and 23-24, the adapter electrical connector 600 may further include a flange 730. The flange 730 protrudes from the outer side surface of the second insulating shell 700 in the lateral direction. The flange 730 may be formed integrally with the second insulating shell 700 using a molding process. The flange 730 may be linear, for example, it may extend only along the first lateral direction YY, or only along the second lateral direction ZZ; or, the flange 730 may be L-shaped, for example, it may extend partially along the first lateral direction YY, and the other part may extend along the second lateral direction ZZ; or, the flange 730 may be annular so as to surround the second insulating shell 700. The second insulating shell 700 may pass through the mounting opening 911 from the inner side of the panel 910 until the first surface 730a of the flange 730 may abut against the inner surface of the panel 910. In this way, only the second mating portion 710 extends to the outside of the panel 910. When the flange 730 abuts against the inner surface of the panel 910, as shown Fig.19 As shown, the second insulating housing 700 and the panel 910 can be fixed by fasteners 840. Therefore, the flange 730 can play a role of limiting, so that the second insulating housing 700 can be conveniently placed in a desired fixed position. In addition, the length of the panel 910 exposed outside the second insulating housing 700 can be reduced. Exemplarily, the flange 730 can be provided on the second mating portion 710 of the second insulating housing 700.

[0130] For example, Fig.19 As shown, the fastener 840 can fix the flange 730 to the panel 910. Specifically, the flange 730 can be provided with a fastening hole 732. The fastener 840 can pass through the through hole 912 on the panel 910 from the outside of the panel 910 and be fixed to the fastening hole 732. In some schemes, the flange is against the panel on the outside of the panel 910, and the fastener is fixed to the panel through the flange. In this case, it is necessary to process a fastening hole on the panel that is compatible with the fastener. However, the panel may not be made from the same manufacturer as the adapter electrical connector 600 and may not be sold at the same time, which increases the difficulty of installing the adapter electrical connector 600. In contrast, by setting the fastening hole 732 on the flange 730, the requirement for the through hole on the panel 910 is reduced a lot, so it can be more convenient to assemble the adapter electrical connector 600 with the panel 910.

[0131] For example, the fastening hole 732 on the flange 730 may be directly processed with an internal thread, and the fastener 840 may be provided with an external thread, so that the fastener 840 is connected to the flange 730 and the panel 910 is clamped therebetween. Fig.21 and Fig.24As shown, a fastening column 780 extending toward the inner side of the panel 910 may be provided on the second surface 730b of the flange 730 opposite to the first surface 730a. The fastening hole 732 may penetrate the fastening column 780 from the first surface 730a. Fig.22a As shown, a nut 740 can be fixed in the fastening hole 732. The fastener 840 can be a screw, so that it can be inserted and threadedly connected to the nut 740. Typically, the flange 730 and the second insulating shell 700 are integrally formed by an insulating material using a molding process, and its mechanical strength is relatively low. The nut 740 can be made of a metal material with high mechanical strength, thereby improving the connection strength between the fastener 840 and the second insulating shell 700. Exemplarily, the nut 740 can be fixed in the fastening hole 732 by any suitable means such as interference fit, bonding, etc. Exemplarily, the nut 740 can be configured as an external hexagonal nut, and at least a portion of the fastening hole 732 can be provided with an internal hexagon matching the nut 740, so as to facilitate fixing the nut 740 in the fastening hole 732. The number of fasteners 840 can be arbitrary. Exemplarily, as Fig.19 As shown, there may be two fasteners 840. The two fasteners 840 may be located at two sides of the second insulating housing 700 along the first lateral direction YY.

[0132] For example, Fig.24 As shown, a reinforcing rib 770 is connected between the fastening column 780, the outer side surface of the second insulating shell 700 and the second surface 730b of the flange 730 to increase the mechanical strength of the integral part. The number of reinforcing ribs 770 can be arbitrary. When the number of reinforcing ribs 770 is multiple, the multiple reinforcing ribs 770 can be arranged at intervals along the circumferential direction of the second insulating shell 700. The reinforcing rib 770 can play a reinforcing role, thereby improving the mechanical strength of the flange 730.

[0133] For example, Figure 22a-22b As shown, the adapting electrical connector 600 may further include a board seal 830. The board seal 830 may surround the second insulating housing 700. The board seal 830 may be clamped between the second insulating housing 700 and the inner surface of the panel 910. In an embodiment where a flange 730 is provided on the outer side of the second insulating housing 700, the board seal 830 may be clamped between the flange 730 and the inner surface of the panel 910. The board seal 830 may improve the sealing between the second insulating housing 700 and the panel 910.

[0134] For example, see Figure 22b and 25, the plate seal 830 may be fixed to a first surface of the flange 730 facing the second mating end 711 along the mating direction XX. In some embodiments, a plate seal groove 731 may be provided on a surface of the flange 730 facing the second mating end 711 along the mating direction XX. The plate seal groove 731 may surround the second insulating housing 700. The plate seal 830 may be fixed to the plate seal groove 731.

[0135] For example, Figure 22b and 25 As shown, the plate seal 830 may be provided with a through hole 833. The fastener 840 may pass through the through hole 833. Thus, the plate seal 830 may also form a seal around the through hole 912 on the panel 910 through which the fastener 840 passes. Thus, dirt may be prevented from entering the interior of the panel 910 through the through hole 912. Moreover, using the same plate seal 830 to seal the through hole 912 and the mounting opening 911 may also reduce the number of parts and reduce processing costs.

[0136] For example, Figure 22a-22b , Fig.23 and Fig.25 As shown, the plate seal 830 may be provided with a head 832 protruding in the lateral direction. The second insulating shell 700 may be provided with a recessed portion 733. The recessed portion 733 may be provided on the surface of the flange 730 facing the second mating end portion 711 along the mating direction XX. The recessed portion 733 may be a part of the groove 731 of the plate seal. The number of the head 832 may be arbitrary, including but not limited to the four shown in the figure. The head 832 may be installed in the recessed portion 733 in a one-to-one correspondence. By installing the head 832 in the recessed portion 733, the plate seal 830 may be better positioned and fixed.

[0137] For example, Figure 12-13 As shown, the first insulating housing 200 may have a first outer surface 203. A housing lock 230 may be provided on the first outer surface 203. The housing lock 230 may include a cantilever buckle 231. Exemplarily, the first outer surface 203 may be the one that is wider in the lateral direction so as to have a sufficiently large space to set the housing lock 230. A gap 240 may be provided between the cantilever buckle 231 and the first outer surface 203. The gap 240 may be used to receive a portion of the adapter electrical connector 600 that is engaged with the cantilever buckle 231, such as a side wall of the second mating portion 710 (such as Figure 4 That is, when the electrical connector 100 is connected to the mating electrical connector 600 , the side wall of the second mating portion 710 can be inserted into the space 240 .

[0138] like Figure 4 , 6As shown in FIGS. 11 and 15 , the electrical connector 100 may further include a connector locking component (CPA) 410. The connector locking component 410 is movable between a locking position and a release position along the mating direction XX. The connector locking component 410 may include a body 411 and a cantilever stopper 412. The cantilever stopper 412 may be connected to the body 411. Fig.10 FIG. 4 shows a state where the connector locking member 410 is in a locked position. In the locked position, the cantilever stopper 412 can abut against the cantilever buckle 231 at the outer side of the cantilever buckle 231 opposite to the gap 240. When the electrical connector 100 is connected to the adapter electrical connector 600, refer to FIG. Fig.10 First, the connector locking component 410 can be pulled in the mating direction XX in a direction away from the first mating portion 201 (e.g., to the left) to move the connector locking component 410 to the release position. In the release position, the stop protrusion 415 on the cantilever limiting portion 412 abuts against the stop portion 235 on the housing lock 230, and the cantilever limiting portion 412 releases the abutment against the outside of the cantilever buckle 231. Then, the first mating portion 201 of the first insulating housing 200 is connected to the second mating portion 710 of the second insulating housing 700 in place, so that the second mating portion 710 is inserted into the gap 240. Next, the connector locking component 410 can be pushed toward the first mating portion 201 to the locking position, at which time the cantilever limiting portion 412 abuts against the outside of the cantilever buckle 231. In this way, it can be prevented that the second mating portion 710 is separated from the first insulating housing 200 due to accidental deformation of the cantilever buckle 231. Conversely, when the electrical connector 100 needs to be unplugged from the adapting electrical connector 600 , the connector locking component 410 can be first moved to the release position, and then the first insulating housing 200 can be unplugged from the second mating portion 710 .

[0139] For example, Figure 6-11 As shown, a protruding support portion 250 may be provided on the first outer surface 203 of the first insulating shell 200. When the connector locking component 410 is in the locked position, the main body 411 of the connector locking component 410 may abut against the support portion 250 in the lateral direction. In this way, the main body 411 of the connector locking component 410 cannot move toward the first outer surface 203 under the action of external force, so the cantilever limiting portion 412 will not deviate from the first outer surface 203 and tilt upward. The cantilever buckle 231 can always be abutted by the cantilever limiting portion 412 and be in a state of being engaged with the adapter electrical connector 600. The front end of the cantilever limiting portion 412 may also be provided with a hook portion 413 bent toward the first outer surface 203, as shown in FIG. Fig.10 and 15As shown, when the connector locking component 410 is in the locking position, the hook portion 413 can cooperate with the inclined surface of the front end of the cantilever buckle 231 to prevent the connector locking component 410 from being separated from the cantilever buckle 231 along the mating direction XX.

[0140] The housing lock 230 is connected to the first insulating housing 200 through a column 233 in the middle thereof, so that the opposite end 234 of the housing lock 230 opposite to the cantilever buckle 231 is also cantilevered. Figure 12-13 As shown. This support of the column 233 makes the cantilever structure at both ends play a role when the electrical connector 100 and the adapting electrical connector 600 are released. Specifically, when the electrical connector 100 and the adapting electrical connector 600 need to be released, as shown in FIG. Fig.10 As shown, the connector locking member 410 is generally pulled out to the left, and the main body 411 can be completely separated from the support portion 250 when it reaches the release position, so that the main body 411 is spaced apart from the first outer surface 203. At this time, the main body 411 can be pressed toward the first outer surface 203 (for example, downward) until the main body 411 abuts against the first outer surface 203. Since the housing lock 230 is supported by the middle column 233, the cantilever buckle 231 can be tilted away from the first outer surface 203 (for example, upward) when the main body 411 is pressed. In this way, the cantilever buckle 231 can be released from the locking adapter portion 714 on the second mating portion 710 of the mating electrical connector 600, and the electrical connector 100 can be pulled out.

[0141] For example, Fig.13 As shown, the housing lock 230 may be provided with a first slide groove 232. The first slide groove 232 may extend along the mating direction XX. The main body 411 of the connector locking component 410 is slidably connected to the first slide groove 232. The first slide groove 232 may play a good guiding role, so that the connector locking component 410 may be moved to a desired position.

[0142] For example, Figure 5-6 As shown in FIG. 18 , the electrical connector 100 may further include an outer shell 500. The outer shell 500 may be sleeved on the first insulating shell 200. The outer shell 500 may protect the first insulating shell 200 to prevent the first insulating shell 200 from being damaged. The outer shell 500 may be made of a material with high mechanical strength. A protruding cover 510 may be provided on the outer shell 500. The cover 510 may surround the cantilever buckle 231. The cover 510 may protect the cantilever buckle 231 and the connector locking component 410 locked with the adapter electrical connector 600 to prevent the adapter electrical connector 600 and the electrical connector 100 from accidentally disengaging. Moreover, the cover 510 may also prevent components such as cables from being entangled with the connector locking component 410 or the cantilever buckle 231, causing them to disengage from the adapter electrical connector 600.

[0143] For example, Figure 5-6 As shown in Figures 18 and 18, the outer shell 500 may have a first end 501 and a second end 502. The first end 501 and the second end 502 may be arranged opposite to each other along the mating direction XX. The first end 501 may face the same direction as the first mating portion 201, that is, facing the first terminal mating contact portion 312 of the plurality of first terminals 310. The outer shell 500 may be provided with a shell opening 520 that exposes the connector locking component 410 and the shell lock 230. The shell opening 520 may extend to the first end 501. In this way, during the connection between the electrical connector 100 and the adapter electrical connector 600, the locking adapter portion 714 (such as Figure 4 , 21 22b) can slide into the housing opening 520 and cooperate with the cantilever buckle 231. Exemplarily, a buckle opening 231a can be provided on the cantilever buckle 231, such as Fig.13 As shown. Figure 4 As shown, when the two electrical connectors are mated, the locking adapter 714 passes over the front end of the cantilever buckle 231 and enters into the buckle opening 231 a and abuts against the side wall of the buckle opening 231 a.

[0144] For example, Fig.18 As shown, the cover portion 510 may include a first cover portion side wall 511, a second cover portion side wall 512 and a top wall 513. The first cover portion side wall 511, the second cover portion side wall 512 and the top wall 513 may be combined to form the cover portion 510. The first cover portion side wall 511 and the second cover portion side wall 512 may extend outward from both sides of the shell opening 520, respectively. The two sides may be opposite to each other along a first lateral direction YY. The top wall 513 may be connected between the first cover portion side wall 511 and the second cover portion side wall 512. The top wall 513 may be adjacent to the first end 501. The first cover portion side wall 511, the second cover portion side wall 512 and the top wall 513 may surround the main locking components of the electrical connector 100 and the adapter electrical connector 600 from three sides, such as the cantilever limit portion 412 and the cantilever buckle 231. Exemplarily, as Figure 5-6 As shown, the cover 510 can expose the main body 411 of the connector locking component 410 , so that it is convenient for the user to install and remove the connector locking component 410 through the main body 411 .

[0145] For example, Fig.18As shown, along the direction from the first end 501 to the second end 502, the first cover side wall 511 and the second cover side wall 512 protrude from the top wall 513. In this way, the longer first cover side wall 511 and the second cover side wall 512 can play a blocking role in the support portion 250, preventing the cable from entering the space between the opposite end 234 of the housing lock 230 and the main body 411 of the connector locking component 410 and the first outer surface 203 of the first insulating housing 200. The shorter top wall 513 can expose the main body 411 of the connector locking component 410, which is convenient for user operation. For example, as Fig.18 As shown, the first cover side wall 511, the second cover side wall 512 and the top wall 513 can extend to the first end 501. In this way, when the electrical connector 100 and the adapting electrical connector 600 are connected in place, as shown in FIG. Figure 4 As shown, the panel 910 can also cover the space inside the cover 510 at the end of the cover 510 to prevent foreign objects from affecting the locking component. Figure 5 As shown, the first cover side wall 511 and the second cover side wall 512 extend to the end surface 414 of the main body 411 facing away from the cantilever stopper 412. Thus, the connector locking component 410 and the housing lock 230 can be protected to the greatest extent while ensuring a simple structure.

[0146] For example, Figure 5 and 18 As shown, the second end 502 of the outer shell 500 is substantially closed, and only a plurality of third channels 531 and a fourth channel 532 may be provided thereon for the first cable 350 and the second cable 360 ​​to pass through, respectively. The plurality of first terminals 310 may pass through the third channels 531 in a one-to-one correspondence. The first signal lead assembly 320 may pass through the fourth channel 532 in a one-to-one correspondence. Thus, the sealing performance of the electrical connector 100 may be ensured.
