Description

Technical Field

[0001] The present application relates to the technical field of electronic equipment, and in particular to a connector and accessories of electronic equipment. Background Art

[0002] In the connection of electronic devices, the design of conventional connector welding structure often arranges the ground pin and power pin on both sides of the high-frequency signal pin. Although this design simplifies the layout and welding process of the connector to a certain extent, its high-frequency shielding effect is particularly insufficient in the environment of high-frequency signal transmission.

[0003] During high-frequency signal transmission, the connector needs to have good shielding performance to reduce the impact of external electromagnetic interference (EMI) and radio frequency interference (RFI) on signal transmission. However, in the conventional connector welding structure, the electromagnetic environment around the high-frequency signal pins becomes complicated due to the arrangement of the ground pins and power pins. The ground pins and power pins may generate unnecessary electromagnetic radiation and interference during high-frequency signal transmission, thereby affecting the signal transmission quality of the high-frequency signal pins.

[0004] Specifically, when high-frequency signals are transmitted through pins (PINs), if the surrounding electromagnetic environment is unstable, it may cause signal attenuation, distortion, or even loss. In conventional connector welding structures, due to interference from ground pins and power pins, the electromagnetic environment around high-frequency signal pins is often difficult to maintain stability. In addition, if the material and manufacturing process of the connector are poor, this interference may be aggravated, further reducing the transmission quality of high-frequency signals.

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0059] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0060] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0061] In some exemplary embodiments, Figure 1-Figure 3 As shown, a connector 1 is applied to an electronic device to achieve stable transmission and efficient connection of internal signals. This electronic device is equipped with a variety of necessary accessories, such as a circuit board 2 and a connector 1, to ensure the normal operation of the device. The connector 1 is assembled and connected with the circuit board 2 to achieve transmission. Alternatively, the connector 1 is plugged with another connector in the electronic device to achieve signal transmission. For example, the connector 1 in this application is a female connector, and a male connector is provided in the electronic device, and the two are plugged and connected.

[0062] The connector 1 has a first direction (see Figure 1 X-axis shown), the second direction (refer to Figure 1 Y axis shown) and thickness direction (refer to Figure 1 The first direction, the second direction and the thickness direction are perpendicular to each other. The connector 1 includes a shielding structure 12 and a terminal assembly 11.

[0063] In this embodiment, if Figure 3 , Figure 7 As shown, the shielding structure 12 includes, for example, an intermediate shielding member 121, which is sandwiched between the first signal terminal group 111 and the second signal terminal group 112. The intermediate shielding member 121 serves as a physical barrier to reduce the impact of external electromagnetic interference on the internal signal transmission of the connector 1, thereby improving the electromagnetic compatibility and overall performance of the connector 1.

[0064] The middle shielding member 121 is provided with a plurality of auxiliary grounding pins 1211 , which further optimizes the grounding path and enhances the shielding effect. The number of the auxiliary grounding pins 1211 is related to the arrangement of the terminal assembly 11 .

[0065] In this embodiment, if Figure 2-Figure 5 , Figure 7 As shown, the connector 1 includes a terminal assembly 11, and the terminal assembly 11 includes, for example, a first signal terminal group 111 and a second signal terminal group 112. The first signal terminal group 111 is, for example, a bottom contact (Bottom Contact) method, which has the advantages of low noise, high temperature stability, fast switching speed, and easy manufacturing.

[0066] The first signal terminal group 111 includes a plurality of first pin portions 1111, which are arranged in sequence along the first direction. The signal definitions between the plurality of first pin portions 1111 can be different or the same to achieve a variety of transmission functions. The first pin portion 1111 is responsible for introducing or exporting the signal into or out of the connector 1 as the starting point or end point of signal transmission.

[0067] The number and signal definition of the first pin portion 1111 are determined according to specific application requirements. At least one of the multiple first pin portions 1111 is used to transmit high-frequency signals. For example, the multiple first pin portions 1111 at least include a first ground pin 1111a, a first high-frequency pin 1111b, a second high-frequency pin 1111c, and a first voltage bus pin 1111d. The first ground pin 1111a, the first high-frequency pin 1111b, the second high-frequency pin 1111c, and the first voltage bus pin 1111d are sequentially arranged in intervals along the first direction of the connector 1, and the first high-frequency pin 1111b and the second high-frequency pin 1111c are located in the middle to optimize the reception and transmission of high-frequency signals. Among them, an auxiliary ground pin 1211 can be sandwiched between the first high-frequency pin 1111b and the second high-frequency pin 1111c to provide necessary grounding support and shielding effect.

[0068] The second signal terminal group 112 is, for example, a top contact type, which has higher collection efficiency and capacity. The second signal terminal group 112 includes a plurality of second pin portions 1121, which are sequentially arranged in intervals along the first direction of the connector 1. The second pin portions 1121 are also key parts of signal transmission, responsible for introducing or exporting signals into or out of the connector 1.

[0069] The signal definitions between the multiple second pin portions 1121 can be different or the same to achieve different transmission functions. The number and signal definition of the second pin portions 1121 are also determined according to specific application requirements. At least one of the multiple second pin portions 1121 is used to transmit high-frequency signals. For example, the multiple second pin portions 1121 at least include a second ground pin 1121a, a third high-frequency pin 1121b, a fourth high-frequency pin 1121c and a second voltage bus pin 1121d. The second ground pin 1121a, the third high-frequency pin 1121b, the fourth high-frequency pin 1121c and the second voltage bus pin 1121d are arranged in sequence along the first direction of the connector 1, and the second ground pin 1121a is arranged adjacent to the first voltage bus pin 1111d of the first signal terminal group 111. Among them, an auxiliary ground pin 1211 can also be sandwiched between the third high-frequency pin 1121b and the fourth high-frequency pin 1121c to provide necessary grounding support and shielding effect.

[0070] In this embodiment, if Figure 2-Figure 5 , Figure 7As shown, the first pin portion 1111, the second pin portion 1121 and the auxiliary ground pin 1211 are arranged side by side to ensure that when it is installed on the circuit board 2, the first pin portion 1111, the second pin portion 1121 and the auxiliary ground pin 1211 can abut against the circuit board 2, thereby achieving contact electrical connection. The above connection method not only simplifies the installation process, but also ensures stable transmission of signals.

[0071] The connector 1 in this embodiment, by providing an auxiliary ground pin 1211 on the middle shield 121, not only significantly enhances its shielding capability and reduces external interference, but also successfully meets the high standard requirements of the latest USB-C connection standard 5 (Thunderbolt 5, referred to as TBT5). This design not only improves the stability and speed of data transmission, but also enhances the durability and compatibility of the connector 1, providing a reliable solution for modern high-speed data transmission applications.

[0072] In some exemplary embodiments, Figure 2-Figure 5 As shown, the first signal terminal group 111 further includes, for example, a plurality of first terminal bodies 1112 , and the first terminal bodies 1112 are connected to the first pin portions 1111 in a one-to-one correspondence, and together form a complete signal transmission channel.

[0073] Each first terminal body 1112 and the corresponding first pin portion 1111 adopt an integrally formed structure, which not only enhances the stability of the structure, but also ensures the continuity and integrity of the signal during transmission. The integrally formed structure can be achieved by injection molding, stamping molding and other processes, and the specific process selection depends on the characteristics of the material and the manufacturing cost.

[0074] In this embodiment, if Figure 2-Figure 5 As shown, the second signal terminal group 112 further includes, for example, a second terminal body 1122 , and the second terminal body 1122 is connected to the second pin portion 1121 in a one-to-one correspondence, and together constitutes another complete signal transmission channel.

[0075] Similar to the first terminal body 1112, each second terminal body 1122 and the corresponding second pin portion 1121 adopt an integrally formed structure to ensure stable signal transmission. This design not only improves the signal transmission efficiency, but also enhances the stability of the structure, so that the connector can maintain stable performance in complex environments.

[0076] During the manufacturing process, the first terminal body 1112 and the first pin portion 1111, and the second terminal body 1122 and the second pin portion 1121 are first formed into a whole through an integrated molding process. Then, the formed terminal assemblies 11 are assembled onto the base of the connector 1 according to a predetermined arrangement order and position. Finally, the terminal assemblies are connected to other connection components through welding, crimping or other connection methods.

[0077] When the connector is inserted into an electronic device, the first signal terminal group 111 and the second signal terminal group 112 are respectively in contact with the corresponding connecting components inside the device to form a signal transmission channel. The signal is transmitted to or from the inside of the device through the first pin portion 1111 and the first terminal body 1112. Similarly, the signal is also transmitted through the second pin portion 1121 and the second terminal body 1122. Due to the use of an integrated molding structure, the attenuation and interference of the signal during the transmission process are greatly reduced, thereby achieving efficient and stable signal transmission.

[0078] The connector 1 in this embodiment realizes efficient and stable signal transmission by adopting an integrated structure to design the terminal body and the pin portion. This design not only improves the overall performance of the connector 1, but also simplifies the manufacturing and installation process and reduces costs.

[0079] In some exemplary embodiments, Figure 3 , Figure 6 As shown, two first signal terminal groups 111 are provided, and two second signal terminal groups 112 are also provided. The two first signal terminal groups 111 and the two second signal terminal groups 112 are alternately arranged in sequence along the first direction of the connector 1. For the sake of convenience of understanding, and for further exemplary description, the two first signal terminal groups 111 are defined as, for example, a first signal terminal group 111A and a first signal terminal group 111B, and the two second signal terminal groups 112 are defined as, for example, a second signal terminal group 112A and a second signal terminal group 112B. Such a grouping design not only optimizes the signal transmission path, but also improves the transmission efficiency.

[0080] The first signal terminal group 111A, the second signal terminal group 112A, the first signal terminal group 111B and the second signal terminal group 112B are sequentially arranged in intervals along the first direction of the connector 1 and can realize different transmission channel functions.

[0081] The first signal terminal group 111A is, for example, a first transmission signal channel in a bottom contact manner, and is defined as being used for data transmission and transmission signals, thereby ensuring that the signal transmission process is clear and stable.

[0082] Among them, the multiple first pins 1111 of the first signal terminal group 111A are respectively the first ground pin 1111aA, the first high-frequency pin 1111bA, the second high-frequency pin 1111cA and the first voltage bus pin 1111dA, the first ground pin 1111aA is the GND1 terminal, the first high-frequency pin 1111bA is the TX2+ terminal, the second high-frequency pin 1111cA is the TX2- terminal, the first voltage bus pin 1111dA is the VBUS1 terminal, and the TX2+ terminal and the TX2- terminal are a pair of data transmission terminals, so as to send two signals with equal amplitudes and opposite polarities. An auxiliary ground pin (Mid Plate GND) 1211 is sandwiched between the first high-frequency pin 1111bA and the second high-frequency pin 1111cA, and a ground pin is set in the middle of the high-frequency signal terminal, which effectively improves the shielding function of the connector 1, meets the latest TBT5 requirements of USB C, and improves the product competitiveness.

[0083] The second signal terminal group 112A is, for example, a first receiving signal channel in a top contact manner, and is defined as being used for data transmission and receiving signals, so that the first signal terminal group 111A and the second signal terminal group 112A realize bidirectional transmission of signals.

[0084] Among them, the multiple second pins 1121 of the second signal terminal group 112A are respectively a second ground pin 1121aA, a third high-frequency pin 1121bA, a fourth high-frequency pin 1121cA and a second voltage bus pin 1121dA, the second ground pin 1121aA is a GND2 terminal, the third high-frequency pin 1121bA is an RX2+ terminal, the fourth high-frequency pin 1121cA is an RX2- terminal, the second voltage bus pin 1121dA is a VBUS2 terminal, and the RX2+ terminal and the RX2- terminal are a pair for the data receiving terminal, so as to judge the original signal of the transmitting terminal by comparing the difference between the two signals. An auxiliary ground pin 1211 is sandwiched between the third high-frequency pin 1121bA and the fourth high-frequency pin 1121cA, which effectively reduces the interference between the terminals in the high-frequency signal terminal and achieves a better shielding effect.

[0085] The first signal terminal group 111B is, for example, a second receiving signal channel in a bottom contact manner, and is defined as being used for transmitting data receiving signals, thereby ensuring that the signal receiving process is clear and stable.

[0086] The first pins 1111 of the first signal terminal group 111B are respectively the first ground pin 1111aB, the first high frequency pin 1111bB, the second high frequency pin 1111cB and the first voltage bus pin 1111dB, the first ground pin 1111aB is the GND3 terminal, the first high frequency pin 1111bB is the RX1+ terminal, the second high frequency pin 1111cB is the RX1- terminal, the first voltage bus pin 1111dB is the VBUS3 terminal, the RX1+ terminal and the RX1- terminal are a pair for the data receiving terminal, so as to judge the original signal of the transmitting terminal by comparing the difference between the two signals. Among them, the first voltage bus pin 1111dB is arranged close to one side of the second signal terminal group 112A, and the first ground pin 1111aB is arranged away from one side of the second signal terminal group 112A.

[0087] An auxiliary ground pin (MidPlate GND) 1211 is sandwiched between the first high-frequency pin 1111bB and the second high-frequency pin 1111cB. A ground pin is set in the middle of the high-frequency signal terminal, which effectively improves the shielding function of the connector 1, meets the latest TBT5 requirements of USB C, and improves product competitiveness.

[0088] The second signal terminal group 112B is, for example, a second transmission signal channel in a top contact manner, and is defined as being used for data transmission and transmission signals, so that the first signal terminal group 111B and the second signal terminal group 112B achieve bidirectional transmission of signals.

[0089] Among them, the multiple second pins 1121 of the second signal terminal group 112B are respectively a second ground pin 1121aB, a third high-frequency pin 1121bB, a fourth high-frequency pin 1121cB and a second voltage bus pin 1121dB, the second ground pin 1121aB is a GND4 terminal, the third high-frequency pin 1121bB is a TX1+ terminal, the fourth high-frequency pin 1121cB is a TX1- terminal, the second voltage bus pin 1121dB is a VBUS4 terminal, and the TX1+ terminal and the TX1- terminal are a pair of data transmission terminals, so as to send two signals with equal amplitudes and opposite polarities. An auxiliary ground pin 1211 is sandwiched between the third high-frequency pin 1121bB and the fourth high-frequency pin 1121cB, which effectively reduces interference between terminals in the high-frequency signal terminal and achieves a better shielding effect.

[0090] The connector 1 in this embodiment has multiple auxiliary grounding pins 1211 that form a one-to-one correspondence with the four signal terminal groups on the connector 1, that is, the multiple auxiliary grounding pins 1211 are, for example, four, to ensure that an auxiliary grounding pin 1211 is provided in each first pin portion 1111 set and each second pin portion 1121 set, thereby ensuring that the signal transmission in each area is effectively grounded and protected, and further consolidating the shielding effect in the high-frequency signal terminal.

[0091] The above layout design not only ensures that each key signal transmission path can be directly grounded and protected, but also forms a continuous and efficient shielding network through the cooperation between the auxiliary grounding pin 1211 and the main pin (i.e., the first pin portion 1111 and the second pin portion 1121), effectively reducing the impact of external electromagnetic interference on the internal signal of the connector 1 and improving the overall performance of the connector 1. The auxiliary grounding pin 1211 is set by using the intermediate shielding member to be inserted in the middle of the high-frequency terminal, which effectively improves the shielding function of the connector 1, meets the latest USB-C TBT5 standard requirements, and effectively improves the product competitiveness.

[0092] In some exemplary embodiments, Figure 2-Figure 5 As shown, the terminal assembly 11 further includes a third signal terminal group 113 and a fourth signal terminal group 114, and the third signal terminal group 113 and the fourth signal terminal group 114 are arranged between the first signal terminal group 111 and the second signal terminal group 112 located in the middle. The third signal terminal group 113 is arranged close to the second signal terminal group 112, and the fourth signal terminal group 114 is arranged close to the first signal terminal group 111. Taking the above embodiment as an example, the third signal terminal group 113 is arranged close to the second signal terminal group 112A, and the fourth signal terminal group 114 is arranged close to the first signal terminal group 111B.

[0093] In this embodiment, if Figure 2-Figure 5 As shown, the third signal terminal group 113 includes a plurality of third terminal bodies 1131 and a plurality of third pin portions 1132 . The third terminal bodies 1131 and the third pin portions 1132 are connected in a one-to-one correspondence, and together constitute a complete signal transmission channel.

[0094] The fourth signal terminal group 114 includes a plurality of fourth terminal bodies 1141 and a plurality of fourth pin portions 1142 . The fourth terminal bodies 1141 and the fourth pin portions 1142 are connected in a one-to-one correspondence, and together form a complete signal transmission channel.

[0095] It is understandable that the molding method of the third signal terminal group 113 and the fourth signal terminal group 114 is the same as or similar to the molding method of the first signal terminal group 111 or the second signal terminal group 112 , and will not be repeated herein.

[0096] The third signal terminal group 113 and the fourth signal terminal group 114 are signal transmission channels for realizing the USB-C 2.0 function. For example, there are four third terminal bodies 1131 and three pin portions 1132, and four fourth terminal bodies 1141 and four fourth pin portions 1142, to realize the corresponding data transmission function.

[0097] It should be noted that the shapes of the above-mentioned multiple first terminal bodies 1112 can be the same or different, wherein the shape can refer to the width, length and extension path of the first terminal body 1112, for example. That is, the extension path of the first terminal body 1112 will change, such as extending along the first direction of the connector 1 or the second direction of the connector 1 to form a mutual avoidance state to avoid mutual interference, and the width of the first terminal body 1112 can be designed based on the signal transmission situation, which is subject to the actual situation. It can be understood that the design logic of the above-mentioned second terminal body 1122, the third terminal body 1131 and the fourth terminal body 1141 is the same or similar to the design logic of the above-mentioned first terminal body 1112, and will not be repeated here.

[0098] Among them, the third pin portion 1132, the fourth pin portion 1142, the first pin portion 1111, the second pin portion 1121 and the auxiliary ground pin 1211 are arranged side by side to ensure the neatness of the pin positions and ensure that they can abut against the circuit board 2 to achieve contact electrical connection.

[0099] In this embodiment, if Figure 2-Figure 5 , Figure 7 As shown, at least one of the first pin portion 1111, the second pin portion 1121, the third pin portion 1132, the fourth pin portion 1142, and the auxiliary ground pin 1211 is a hook-shaped structure. The first pin portion 1111 is taken as an example for further description.

[0100] The first pin portion 1111, for example, includes a first bending section 11111, a first straight section 11112, a first inclined section 11113, and a second bending section 11114, which are connected in sequence. The first bending section 11111 is bent relative to the first terminal body 1112 and extends along the thickness direction of the connector 1, that is, it serves as the starting part of the first pin portion 1111 and extends downward. The first straight section 11112 is bent relative to the first bending section 11111 and extends along the second direction of the connector 1, that is, it extends in a direction away from the first terminal body 1112, extending the overall length of the first pin portion 1111 along the second direction, so as to ensure that the first pin portion 1111 can abut against the circuit board 2, and provide a basis for subsequent tilting and bending.

[0101] The first inclined section 11113 is inclined relative to the first straight section 11112, that is, it is inclined upward, so that the first inclined section 11113 and the first straight section 11112 form a preset angle, and the preset angle is, for example, any value between 100° and 150°. The larger the preset angle, the tighter the contact connection between the first pin portion 1111 and the circuit board 2 can be ensured.

[0102] The extension direction of the first inclined section 11113 and the extension direction of the first bending section 11111 are in opposite directions, that is, the first bending section 11111 has a downward extension trend, and the first inclined section 11113 has an upward inclination trend, forming a rotation path, which can ensure that the size of the first pin portion 1111 in the thickness direction of the connector 1 is not too large, which is conducive to thinning the overall thickness of the connector 1 and realizing a compact design.

[0103] The second bending section 11114 is bent relative to the first inclined section 11113 and extends in the thickness direction of the connector 1, that is, in the vertical direction, which can increase the abutment surface of the second bending section 11114 and improve the stability of the connection. Each turning connection position in the first pin portion 1111 is chamfered to reduce sharp parts and effectively avoid damage to other components of the connector 1.

[0104] Exemplarily, the first pin portion 1111 includes a first turning arc segment 11115 and a second turning arc segment 11116, the first inclined segment 11113 is connected to the first turning arc segment 11115, the first turning arc segment 11115 is configured to be chamfered for the first time, and the first turning arc segment 11115 is used to abut against the circuit board 2 to form a contact connection therewith. The notch of the first turning arc segment 11115 is located on the side away from the circuit board 2, so that the arc surface of the first turning arc segment 11115 can form an elastic abutment with the circuit board 2, thereby avoiding damage to the circuit board 2 and improving the safety of the connection.

[0105] The first turning arc segment 11115 is connected to the second turning arc segment 11116, and the second turning arc segment 11116 is constructed as a second chamfering treatment, and the notch of the first turning arc segment 11115 is set in an opposite direction to the notch of the second turning arc segment 11116, that is, the notch of the second turning arc segment 11116 is facing one side of the circuit board 2.

[0106] The second turning arc section 11116 is connected to the second bending section 11114, and the second bending section 11114 extends upward, thereby changing the extension path of the first pin portion 1111. The second bending section 11114 is the free end of the first pin portion 1111. When the first pin portion 1111 is squeezed by the circuit board 2, the first turning arc section 11115 is squeezed, so that the first pin portion 1111 is deformed, and the first turning arc section 11115 drives the first inclined section 11113 and the first turning arc section 11115 to move, thereby changing the angle of the preset angle and the position of the second bending section 11114. Among them, the second bending section 11114 will eventually abut against other components of the connector 1 to prevent the further movement of the second bending section 11114, thereby ensuring that the second turning arc section 11116 and the circuit board 2 are always in contact, thereby enhancing the dynamic stability and adaptability of the connection.

[0107] It should be noted that the chamfering treatment in the first pin portion 1111 is not limited to between the first inclined section 11113 and the second bent section 11114, but can also be performed between the first bent section 11111 and the first straight section 11112 and between the first straight section 11112 and the first inclined section 11113, thereby reducing sharp parts, avoiding damage to the circuit board 2 or other components during the connection process, and improving the safety of the connection.

[0108] It can be understood that the structures of the second pin portion 1121, the third pin portion 1132, the fourth pin portion 1142, and the auxiliary grounding pin 1211 are the same as or similar to the first pin portion 1111, and their hook bodies are bent and extended upward with the hook mouth facing upward, and can be deformed to achieve elastic abutment with the circuit board 2, which will not be repeated here.

[0109] It should also be noted that the descriptions of directions in this application, such as up, down, etc., are all illustrative of the directions in the diagram for the convenience of understanding and description, and do not constitute a limitation to this application. The directions will vary in different application scenarios.

[0110] In some exemplary embodiments, Figure 2-Figure 5 , Figure 7 , Figure 9-11 As shown, the connector 1 also includes an insulating structure 13. The insulating structure 13 is made of a material with insulating properties, for example. The insulating structure 13 is formed on the terminal assembly 11 by injection molding, such as covering the terminal assembly 11, so as to isolate different signal terminals in the terminal assembly 11 from each other to prevent signal crosstalk, and at the same time support and fix the terminal assembly 11 to enhance the stability of the terminal assembly 11 and prevent it from shaking or shifting.

[0111] Among them, the first pin portion 1111, the second pin portion 1121, the third pin portion 1132, the fourth pin portion 1142, and the auxiliary ground pin 1211 can pass through the insulating structure 13 to form a contact-type electrical connection with the circuit board 2. Taking the first pin portion 1111 as an example, the projection of the first pin portion 1111 in the second direction of the connector 1 can fall inside the boundary of the insulating structure 13, effectively utilizing the thickness space of the connector 1, avoiding increasing the overall thickness of the connector 1, and facilitating the thin design of the connector 1. When the first pin portion 1111 is in contact-type connection with the circuit board 2, the first pin portion 1111 will be deformed, and the opening of the hook mouth will become smaller.

[0112] The first terminal body 1112 , the second terminal body 1122 , the third terminal body 1131 and the fourth terminal body 1141 are located on a side away from the auxiliary ground pin 1211 , and part of the structure is exposed to facilitate connection with a male connector to achieve signal transmission.

[0113] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 9-11 As shown, the insulating structure 13 includes, for example, a first insulating member 131, a second insulating member 132 and a third insulating member 133, which work together to construct an insulating barrier of the connector 1. The first insulating member 131 and the second insulating member 132 are arranged at intervals along the thickness direction of the connector 1 and attached to both sides of the middle shielding member 121 to fix the middle shielding member 121.

[0114] The first insulating member 131 is used to support and fix the first terminal body 1112 of the first signal terminal group 111 and the third terminal body 1131 of the third signal terminal group 113. The first insulating member 131 can cover a part of the structure of the first terminal body 1112 and the third terminal body 1131, so as to realize the fixation of the first terminal body 1112 and the third terminal body 1131 and improve the stability of the first signal terminal group 111 and the third signal terminal group 113. The uncovered first terminal body 1112 and the third terminal body 1131 will form a contact electrical connection with the male connector.

[0115] It can be understood that the function and role of the second insulating member 132 are the same or similar to those of the first insulating member 131. The second insulating member 132 is used to support and fix the second terminal body 1122 of the second signal terminal group 112 and the fourth terminal body 1141 of the fourth signal terminal group 114. The second insulating member 132 can cover part of the structure of the second terminal body 1122 and the fourth terminal body 1141, so as to achieve the fixation of the second terminal body 1122 and the fourth terminal body 1141 and improve the stability of the second signal terminal group 112 and the fourth signal terminal group 114. The uncovered second terminal body 1122 and the fourth terminal body 1141 will form a contact electrical connection with the male connector.

[0116] The third insulating member 133 is molded to cover the first insulating member 131 and the second insulating member 132, which not only realizes the integration of the connector 1, but also enhances the insulation effect by tightly wrapping. In addition, the third insulating member 133 can also wrap a part of the terminal assembly 11 to play an additional supporting and fixing role.

[0117] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 9-11 As shown, the first insulating member 131 has a first limiting through hole 1311, the second insulating member 132 has a first limiting block 1321, and the intermediate shielding member 121 is provided with a first through hole 1212. The first limiting block 1321 can pass through the first through hole 1212 and extend into the first limiting through hole 1311 for positioning and plugging to achieve interlocking.

[0118] In order to cooperate with other components, some limiting structures or recessed hole structures are also provided on the first insulating member 131 to achieve the adaptability of various components in the connector 1.

[0119] For example, the first insulating member 131 is further provided with a plurality of first avoidance grooves 1312, which can expose a portion of the first signal terminal group 111 to reduce the obstruction of the insulating material to signal transmission. The position of the first avoidance grooves 1312 can be adaptively designed according to actual conditions.

[0120] For example, the first insulating member 131 is also provided with a plurality of first protrusions 1313, and the first protrusions 1313 can be buried in the third insulating member 133. The first protrusions 1313 play a role of support and mutual restraint with the third insulating member 133, thereby improving the reliability and stability of the connection between the first insulating member 131 and the third insulating member 133.

[0121] For example, the first insulating member 131 is also provided with a plurality of first positioning posts 1314, the first positioning posts 1314 cooperate with the intermediate shielding member 121, and the intermediate shielding member 121 is provided with a plurality of first positioning holes 1213, for example, the first positioning posts 1314 are plugged and connected with the first positioning holes 1213 in a one-to-one correspondence, so as to improve the stability of the first insulating member 131 and the intermediate shielding member 121 during installation. Among them, the first positioning posts 1314 can be provided with two, and they are provided along the diagonal lines of the first direction and the second direction, so as to realize a foolproof design. It should be noted that the second insulating member 132 can also be provided with a corresponding first plug hole 1322, and the first positioning posts 1314 are inserted into the corresponding first plug hole 1322 to further realize interlocking.

[0122] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 9-11 As shown, it can be understood that the interlocking is not limited to the above-mentioned method. The second insulating member 132 may be provided with a second limiting through hole 1323, the first insulating member 131 may be provided with a second limiting block 1315, the intermediate shielding member 121 may be provided with a second through hole 1214, the second limiting block 1315 passes through the second through hole 1214, and is positioned and plugged with the second limiting through hole 1323 to achieve interlocking. The first limiting block 1321 and the second limiting block 1315 are arranged on both sides along the first direction of the connector 1, so that both sides can achieve interlocking, thereby improving the stability during connection.

[0123] In order to cooperate with other components, the second insulating member 132 is also provided with some limiting structures or recessed hole structures, etc., so as to achieve the adaptability of various components in the connector 1.

[0124] For example, a plurality of second avoidance grooves 1324 are further disposed on the second insulating member 132 , and the plurality of second avoidance grooves 1324 can expose a portion of the second signal terminal group 112 , thereby reducing the obstruction of the insulating material to signal transmission.

[0125] For example, the second insulating member 132 is also provided with a plurality of second protrusions 1325, which can be buried in the third insulating member 133. The second protrusions 1325 play a role of support and mutual restraint with the third insulating member 133, thereby improving the reliability and stability of the connection between the second insulating member 132 and the third insulating member 133.

[0126] For example, the second insulating member 132 is also provided with a plurality of second positioning posts 1326, and the second positioning posts 1326 cooperate with the intermediate shielding member 121. For example, the intermediate shielding member 121 is provided with a plurality of second positioning holes 1215, and the second positioning posts 1326 are plugged and connected with the second positioning holes 1215 in a one-to-one correspondence, thereby improving the stability of the second insulating member 132 and the intermediate shielding member 121 during installation. Among them, the second positioning posts 1326 can be provided with two, and they are provided along the diagonal lines of the first direction and the second direction, and a foolproof design can also be realized. It should be noted that a corresponding second plug hole 1316 can also be provided on the first insulating member 131, and the second positioning posts 1326 are inserted into the corresponding second plug hole 1316 to further realize interlocking.

[0127] The third insulating member 133 can also wrap the terminal assembly 11 to play a supporting and fixing role, and a part of the terminal assembly 11 is in an exposed state to form a contact connection with the male connector.

[0128] The connector 1 in this embodiment realizes a high-performance and high-stability connector 1 through the layout of the split insulating parts and the interlocking mechanism design between the insulating parts. The connector 1 can not only effectively isolate different signal terminals to prevent signal interference, but also ensure the pure transmission of signals and the structural stability of the connector, providing a strong guarantee for the reliable operation of modern electronic equipment.

[0129] In some exemplary embodiments, Figure 2-Figure 5 , Figure 7 , Figure 8 , Fig.11 As shown, the shielding structure 12 includes an outer shielding member 122, which is a cylindrical structure, so that the outer shielding member 122 can be sleeved on the insulating structure 13 to shield and isolate the outside, avoid electromagnetic interference, and ensure the stability and quality of signal transmission.

[0130] The outer shielding member 122 includes a first part 1221 and two second parts 1222. The first part 1221 is a cylindrical structure, which not only enhances the overall structural strength of the connector 1, but more importantly, provides a continuous electromagnetic shielding layer for the connector 1, effectively blocking electromagnetic interference from the outside and protecting the pure transmission of internal signals.

[0131] The first part 1221 is located on a side away from the first pin portion 1111, and is spaced apart from the terminal assembly 11 of the connector 1, so as to reserve space for the male connector to be plugged in, and ensure that there is no obstruction when the male connector is inserted. The first part 1221 is provided with a plurality of contact spring arms 12211, and when plugged in with the male connector, the plurality of contact spring arms 12211 can abut against the male connector, so that it is in close contact with the outer shielding member 122 or the terminal assembly 11, and ensure that the signal can be transmitted normally.

[0132] Exemplarily, the shapes of the multiple contact spring arms 12211 can be the same or different. For example, the contact spring arm 12211 can be in the shape of a hemispherical convex hull, and its smooth surface can protect the male connector; or, the contact spring arm 12211 can be in the shape of a V, which effectively contacts the male connector, and the tip portion is rounded to avoid scratching the male connector and extend the service life of the male connector; or, the contact spring arm 12211 can be in the shape of a spring sheet, and its free end can abut against the male connector, and the abutting position of the free end is chamfered to avoid damaging the male connector, thereby optimizing the contact effect and extending the service life of the connector 1.

[0133] The second portion 1222 is disposed close to the first pin portion 1111 , and the two second portions 1222 are symmetrically disposed along the thickness direction of the connector 1 , and are both connected to the insulation structure 13 .

[0134] Exemplarily, a limiting spring sheet 12221 is provided on the second part 1222, and the second part 1222 can be detachably connected to the insulating structure 13 through the limiting spring sheet 12221, and is installed in a limited position, which effectively improves the installation efficiency. The limiting spring sheet 12221 can be one or more, and when there are multiple limiting spring sheets 12221, they are symmetrically arranged along the first direction of the connector 1 and / or symmetrically arranged along the thickness direction of the connector 1 to ensure the balance and stability of the installation.

[0135] The third insulating member 133 of the insulating structure 13 is provided with a limiting groove 1331 matching the limiting spring piece 12221, the fixed end of the limiting spring piece 12221 is connected to the second part 1222, and the free end of the limiting spring piece 12221 can extend into the limiting groove 1331 to achieve snap connection. When disassembly is required, the limiting spring piece 12221 can be deformed under the action of external force, so as to easily detach from the limiting groove 1331, which greatly improves the efficiency of installation and disassembly.

[0136] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 8 , Fig.11As shown, the intermediate shielding member 121 of the shielding structure 12 is buried in the insulating structure 13, which not only enhances the stability of the intermediate shielding member 121, but also avoids the loosening or displacement problems that may occur in a vibration or impact environment through the fixing effect of the insulating structure 13. Part of the structure of the intermediate shielding member 121 can pass through the insulating structure 13 to facilitate connection with the corresponding part.

[0137] For example, the intermediate shielding member 121 is provided with two first protrusions 1216, which are symmetrically arranged along the second direction of the connector 1, and the first protrusions 1216 can pass through the insulating structure 13 and abut against other components, such as the shell structure 15 described later, thereby achieving a reliable grounding connection. This design not only enhances the electrical safety of the connector 1, but also helps to guide possible electromagnetic interference into the ground, further improving the electromagnetic compatibility of the connector 1.

[0138] For another example, the intermediate shield 121 is provided with two second protrusions 1217, which are symmetrically arranged along the second direction of the connector 1. The second protrusions 1217 can pass through the insulating structure 13, and the second protrusions 1217 can be in close contact with the corresponding parts on the male connector to ensure stable signal transmission. This design not only meets the signal transmission requirements of the connector 1, but also effectively avoids the influence of electromagnetic interference on the signal quality through the isolation effect of the intermediate shield 121.

[0139] The shielding structure 12 in this embodiment realizes a high-performance and high-stability connector 1 through the detachable assembly structure of the outer shielding member 122, the electromagnetic shielding and signal transmission functions of the intermediate shielding member 121, and the dual design of grounding and signal transmission. This connector can not only effectively improve electromagnetic compatibility, but also ensure the purity and stability of signal transmission, providing a strong guarantee for the reliable operation of modern electronic equipment.

[0140] In some exemplary embodiments, Figure 2-Figure 5 , Figure 7 , Figure 8 , Figure 11-13 As shown, the connector 1 includes an isolation seat 14 , which is disposed on one side of the insulation structure 13 along the second direction of the connector 1 and is respectively connected to the insulation structure 13 and the outer shielding member 122 .

[0141] Among them, the isolation seat 14 is provided with multiple isolation through holes 141, and the first pin part 1111, the second pin part 1121, the third pin part 1132, the fourth pin part 1142, and the auxiliary grounding pin 1211 are respectively inserted into the corresponding isolation through holes 141 to separate adjacent pin structures, etc., to avoid the risk of electrical short circuit caused by direct contact between the above-mentioned pin structures.

[0142] The isolation through hole 141 is, for example, rectangular in shape, and has sufficient accommodation space to place the above-mentioned pin structure, ensuring that the above-mentioned pin structure can remain stable after insertion and is not easy to shake or fall off. Among them, although each isolation through hole 141 has similar rectangular features in structure, they show a certain flexibility in size. For example, along the thickness direction of the connector 1, the lengths of each isolation through hole 141 can be the same, or they can be different as needed. Similarly, along the first direction of the connector 1, the widths of each isolation through hole 141 can also remain consistent or differ. This dimensional flexibility can not only enable the isolation seat 14 to better adapt to pin structures of different sizes and shapes, thereby improving the versatility and practicality of the connector 1, but also realize a fool-proof design and improve the assembly efficiency of the connector 1.

[0143] Further exemplary description is given with the illustrated orientation, for example, the upper boundaries of all the isolation through holes 141 are flush, and the lower boundaries of the isolation through holes 141 are flush or misaligned. For example, the isolation through holes 141 in the first pin portion 1111 set have the same length along the thickness direction of the connector 1, and the width of the first pin portion 1111 along the first direction of the connector 1 is adaptively designed based on; the isolation through holes 141 in the second pin portion 1121 set have the same length along the thickness direction of the connector 1, and the width of the second pin portion 1121 along the first direction of the connector 1 is adaptively designed based on; wherein, the length of the second pin portion 1121 set along the thickness direction of the connector 1 is less than the length of the first pin portion 1111 set along the thickness direction of the connector 1, so as to meet the differences in the pin structure, thereby realizing a foolproof design, avoiding reverse or wrong installation, and effectively improving assembly efficiency. It can be understood that the design logic of the pin structures such as the third pin portion 1132 and the fourth pin portion 1142 is the same as or similar to the design logic of the first pin portion 1111 and the second pin portion 1121, and will not be repeated here.

[0144] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 8 , Figure 11-13 As shown, a shielding wall 142 may also be provided on the inner side wall of the isolation through hole 141, and the shielding wall 142 is located on a side of the isolation through hole 141 away from the insulating structure 13. The following takes the first pin portion 1111 as an example to further explain the connection between the first pin portion 1111 and the shielding wall 142, thereby avoiding unnecessary contact with adjacent pin structures and ensuring the stability and safety of the connector 1.

[0145] When the first pin portion 1111 is not squeezed by the circuit board 2, the first pin portion 1111 is reset, and the first turning arc segment 11115 drives the first inclined segment 11113 and the second turning arc segment 11116 to move to restore to the original position. The second bending segment 11114 can abut against the shielding wall 142 to prevent the second bending segment 11114 from further moving along the second direction, effectively preventing the second bending segment 11114 from accidentally detaching from the isolation through hole 141, and avoiding the second bending segment 11114 from moving outside the isolation through hole 141 and contacting the adjacent first pin portion 1111 or the auxiliary grounding pin 1211, resulting in electrical connection problems.

[0146] It is understandable that a similar shielding wall (not shown in the figure) can also be provided on the opposite side of the shielding wall 142 in the isolation through hole 141. Such a design can also effectively prevent the further movement of the second bending section 11114 when the first pin portion 1111 is squeezed by the circuit board 2, and prevent the first pin portion 1111 from having a gap or separation from the circuit board 2, thereby ensuring a good connection effect. The setting of such a shielding wall can be flexibly selected according to actual conditions to meet different application requirements.

[0147] It should be noted that the connection method between the second pin portion 1121, the third pin portion 1132, the fourth pin portion 1142, the auxiliary ground pin 1211 and the isolation through hole 141 is the same or similar to the connection method between the first pin portion 1111 and the isolation through hole 141. This means that the second pin portion 1121, the third pin portion 1132, the fourth pin portion 1142, and the auxiliary ground pin 1211 will also be restricted by the shielding wall to prevent them from being out of the preset position, thereby maintaining the stability and safety of the connector 1. The specific connection method refers to the description between the first pin portion 1111 and the isolation through hole 141, and will not be repeated here.

[0148] The isolation seat 14 in this embodiment can effectively limit the movement range of the pin structure and prevent unnecessary contact and electrical connection problems. The flexible setting of the shielding wall can improve the stability, applicability and overall performance of the connector 1, and also provide users with more convenience and protection when selecting and using the connector 1.

[0149] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 8 , Figure 11-13 As shown, the isolation seat 14 is connected to the insulating structure 13 to achieve an assembly connection and improve the stability of the isolation seat 14 during installation.

[0150] The isolation seat 14 includes, for example, an isolation body 143 and a connecting support 144, and the connecting support 144 is connected to the isolation body 143. The isolation body 143 is connected to the insulating structure 13 along the second direction of the connector 1, and the connecting support 144 is connected to the insulating structure 13 along the thickness direction of the connector 1 to improve the overall stability of the isolation body 143. The connecting support 144 can be one or more, and can be flexibly designed according to actual needs.

[0151] First example

[0152] The connecting support 144 can be provided as one, for example, in the shape of a flat plate, and attached to the insulating structure 13. The connecting support 144 and the insulating structure 13 can be connected by snapping or buckling, etc., to prevent the isolation seat 14 from being separated.

[0153] Second example

[0154] For example, two connecting branches 144 are provided, and the two connecting branches 144 are arranged opposite to each other along the thickness direction of the connector 1, and each connecting branch 144 is fixedly connected to the isolation body 143. The two connecting branches 144 sandwich the insulating structure 13 in the middle, thereby improving the stability of the isolation seat 14 and preventing the isolation seat 14 from shaking or misaligning during use, thereby ensuring the alignment and installation accuracy of the pin structure.

[0155] In order to further realize foolproof design and speed up installation, one side surface of one connecting support 144 along the thickness direction of the connector 1 and facing the insulating structure 13 is stepped to distinguish the structural shapes of the two connecting supports 144, which is convenient for operators to install quickly. The step shape of the connecting support 144 includes, for example, a first table 1441 and a second table 1442, and the first table 1441 and the second table 1442 are located in different planes. When they are connected with the third insulating member 133 of the insulating structure 13, they can also achieve position limiting and improve the accuracy of connection.

[0156] For example, the third insulating part 133 of the insulating structure 13 is provided with an embedding groove 1332, and the number of the embedding grooves 1332 corresponds to the number of the connecting branches 144, and the shape thereof matches the connecting branches 144, so that the connecting branches 144 can be embedded in the corresponding embedding grooves 1332, which can not only realize positioning or limiting connection, but also ensure the flatness during connection, thereby avoiding increasing the thickness of the connector 1.

[0157] In this embodiment, if Figure 2-Figure 5 , Figure 7 , Figure 8 , Figure 11-13As shown, a limiting buckle 145 is provided on the connecting support 144, and the connecting support 144 is connected to the shielding structure 12 by the limiting buckle 145, which is easy to assemble and improves the convenience of installation and disassembly.

[0158] The limiting buckle 145 is arranged on a side of the connecting support 144 away from the insulating structure 13. The limiting buckle 145 can be one or two, and the two limiting buckles 145 are arranged at intervals. Exemplarily, the limiting buckle 145 includes a limiting protrusion 1451 and a wedge 1452. The limiting protrusion 1451 protrudes from the connecting support 144, and the limiting protrusion 1451 is fixedly connected to the wedge 1452. Among them, the wedge 1452 is located on the side of the limiting protrusion 1451 away from the isolation body 143, so as to facilitate connection with the shielding structure 12. The outer shielding member 122 of the shielding structure 12 is provided with a limiting hole 12222 matching the limiting buckle 145. The limiting hole 12222 and the limiting buckle 145 are precisely plugged in, so that the number of the detachable assembly limiting holes 12222 of the outer shielding member 122 and the isolation seat 14 is consistent with the number of the limiting buckles 145, so as to achieve one-to-one positioning plug-in, which not only simplifies the assembly process but also enhances the stability of the connection.

[0159] During the installation process, the shielding structure 12 slides along the wedge surface of the wedge 1452. This design makes the installation process smoother. When the limit buckle 145 completely enters the limit hole 12222, the limit convex body 1451 and the limit hole 12222 interfere with each other to prevent the limit convex body 1451 from being separated from the limit hole 12222, thereby improving the reliability of the connection between the isolation seat 14 and the shielding structure 12.

[0160] The isolation seat 14 and its connection with the insulation structure 13 and the shielding structure 12 in this embodiment significantly improve the stability and installation convenience of the connector 1, which not only optimizes the connection structure but also improves the overall performance and reliability of the connector 1.

[0161] In some exemplary embodiments, Figure 2 , Figure 3 , Fig.14 As shown, the connector includes a shell structure 15, an insulating structure 13, the shell structure 15 and a terminal assembly 11, which work together to provide a stable and reliable signal connection for the electronic device. The shell structure 15 is sleeved on the outside of the outer shielding member 122 and is respectively connected to the outer shielding member 122 and the third insulating member 133 of the insulating structure 13. For example, welding can be selected as the connection method to improve the reliability of the connection.

[0162] In this embodiment, if Figure 2 , Figure 3 , Fig.14As shown, the shell structure 15 includes, for example, a shell 151 and at least one first shell support 152. The shell 151 is annular and is sleeved on the insulating structure 13 to be respectively connected to the third insulating member 133 of the insulating structure 13 and the second portion 1222 of the shielding structure 12. The first protrusion 1216 of the intermediate shielding member 121 in the shielding structure 12 passes through the insulating structure 13 and abuts against the shell 151.

[0163] The first shell support 152 is plate-shaped and covers the first portion 1221 of the shielding structure 12. The first shell support 152 has two connecting ears 1521 symmetrically arranged along the second direction of the connector 1, and the two connecting ears 1521 can overlap the circuit board 2. The connecting ears 1521 are provided with connecting holes 1522, and the fasteners 3 can pass through the connecting holes 1522 to connect with the circuit board 2 to achieve the fixation of the connector 1. The fasteners 3 are, for example, screws, bolts, etc., which are threadedly connected with the circuit board 2 to improve the reliability of the connection.

[0164] It should be noted that the above-mentioned first shell support body 152 can be one or two. The two first shell supports 152 can be arranged along the first direction of the connector 1. Each first shell support body 152 is integrally formed with the shell 151 to enhance the overall strength of the shell structure 15.

[0165] In the connector 1 of this embodiment, the shell structure 15 is sleeved on the outside of the insulating structure 13, which not only enhances the mechanical strength of the connector 1, but also provides an additional protective barrier to prevent external factors from causing damage to the inside of the connector 1. In addition, the insulating structure 13 can also play a role of partial support for the shell structure 15, providing it with mechanical strength, and the shell structure 15 can provide protection to prevent external interference to its inside, thereby improving the overall stability and safety.

[0166] The shell structure 15 is attached to the circuit board 2, and the shell structure 15 is detachably connected to the circuit board 2 through the fastener 3, which improves the convenience of installing and removing the connector 1. The fastener 3 is, for example, a bolt or a screw, which can improve the stability during installation and is also convenient for replacing the connector 1.

[0167] like Figure 1-Figure 3 , Fig.14 , Fig.15 As shown, the present application also provides an accessory for an electronic device, including a fastener 3, a circuit board 2, and a connector 1 as in any of the above embodiments, wherein the connector 1 is detachably connected to the circuit board 2 via the fastener 3, which is convenient for disassembly and installation, and improves the flexibility during assembly. If the connector 1 needs to be replaced, it can be easily disassembled by simply removing the fastener 3, without the need for complicated welding operations, which is both convenient and quick.

[0168] Exemplarily, the connection ear 1521 of the shell structure 15 is attached to the circuit board 2, and the circuit board 2 is provided with a screw hole 23. One end of the fastener 3 passes through the connection ear 1521 and is threadedly connected to the screw hole 23 to improve the stability of the circuit board 2 and the connector 1 when connected. The fastener 3 is, for example, a screw or a bolt, which is simple and easy to implement. Two screw holes 23 can be provided to be consistent with the connection ear 1521 to achieve balance.

[0169] Among them, the side of the circuit board is provided with a conductive sheet 22, which is electrically connected to the terminal assembly 11 of the connector 1 by contact. The connection method is simple, which can effectively reduce the surface mounting technology process and manpower, making the process operation smoother and effectively improving production efficiency. In addition, the contact connection does not require a high-temperature welding process, which effectively avoids the problem of material deformation that may be caused by high-temperature welding.

[0170] In this embodiment, if Figure 1-Figure 3 , Fig.14 , Fig.15 As shown, a receiving space 21 is provided on the side of the circuit board 2, and the cross-sectional shape of the receiving space 21 is adapted to the shape of the connector 1 to ensure that the connector 1 can be embedded in the receiving space 21, so that the two side surfaces of the circuit board 2 along the thickness direction of the connector 1 can be lower than the surface of the connector 1, thereby reducing the overall thickness of the electronic device accessories and facilitating the thin design of the electronic device.

[0171] The cross-sectional shape of the accommodation space 21 is, for example, a T-shape, which can limit the connector 1, such as movement in the first direction and the second direction. Exemplarily, the accommodation space 21 includes a first accommodation area 211 and a second accommodation area 212, the first accommodation area 211 and the second accommodation area 212 are connected, and the first accommodation area 211 and the second accommodation area 212 are jointly configured to accommodate the connector 1.

[0172] In this embodiment, if Figure 1-Figure 3 , Fig.14 , Fig.15 As shown, a conductive sheet 22 is disposed on the side wall surface of the accommodation space 21 opposite to the side of the circuit board 2, and the accommodation space 21 is used to accommodate the connector 1, so that the conductive sheet 22 is disposed correspondingly to the terminal assembly 11 of the connector 1 to achieve contact connection. For example, the conductive sheet 22 includes a plurality of electrical connectors 221, and the plurality of electrical connectors 221 are sequentially spaced and disposed on the side wall surface, and the electrical connectors 221 correspond one-to-one to the terminal assembly 11 of the connector 1 and are contact-connected electrically.

[0173] It is understandable that the circuit board 2 is designed according to the specific functional requirements of the electronic device, and various electronic components, chips and circuit wiring are integrated thereon to achieve specific electrical functions and signal processing, etc.

[0174] The connector 1 adopts the connector 1 described in any embodiment of the present application, and the connector 1 has excellent electrical connection performance and mechanical stability, and can ensure stable and reliable connection with external devices or power supplies. The design of the connector 1 takes into account the compatibility with the circuit board 2, including factors such as pin layout, spacing, and size, to ensure that the two can fit closely.

[0175] During the design phase of the circuit board 2, corresponding soldering holes or sockets are reserved according to the soldering pin layout of the connector 1. The position, size and shape of the soldering holes or sockets are precisely matched with the soldering pins of the connector.

[0176] The electronic device accessory provided in this embodiment integrates high-quality connector 1 and circuit board 2 and adopts precise assembly process to achieve a stable connection between the two. This accessory not only improves the overall performance and reliability of the electronic device, but also simplifies the assembly and maintenance process of the electronic device, reducing costs and time consumption.

[0177] The connector provided in the present application has a structure of contact-type electrical connection with the circuit board, and realizes electrical connection and mechanical fixation between the connector and the circuit board through elastic deformation of the pin structure, eliminating the need to use solder paste and high-temperature furnace for welding, thereby improving the safety of the connector. At the same time, the connector also uses fasteners to fix the connector to the circuit board, further enhancing the firmness and stability of the connection.

[0178] The soldering-free method of the connector in this application brings many advantages. For example, it effectively reduces the SMT process and labor costs, makes the operation smoother, and improves production efficiency. Secondly, since there is no need to go through the heating process of a high-temperature furnace, the connector will not be deformed, thereby ensuring the performance and reliability of the connector. In addition, if the connector needs to be replaced, it can be easily disassembled by simply unscrewing the screws, without the need for complicated soldering operations, which is convenient and quick. Most importantly, this soldering-free method can also meet the requirements of high-frequency signal transmission such as USB 4.0, providing a more reliable and efficient connection solution for future electronic products.
