[0050] In order to solve the technical problem that the plurality of signal terminals 3 are easily misaligned when connected with the plurality of metal contacts 12 on the circuit board 1, resulting in that the connector cannot be normally used, the application provides a connector, wherein the first foolproof part 11 is arranged on the circuit board 1, and the second foolproof part 21 is arranged on the connection module, the first foolproof part 11 and the second foolproof part 21 are matched to realize the assembly positioning between the circuit board 1 and the connection module, so that the plurality of metal contacts 12 on the circuit board 1 can be accurately positioned with the plurality of signal terminals 3 in the connection module, and then the plurality of signal terminals 3 and the plurality of metal contacts 12 are accurately connected, ensuring the stable and accurate transmission of the connector signal, avoiding signal attenuation or interruption caused by poor connection.

[0051] Please refer to Figures 1 to 14 , the embodiment of the application provides a connector, comprising a circuit board 1 and a connection module, the first foolproof part 11 is arranged on the circuit board 1, and the second foolproof part 21 is arranged on the connection module, and the second foolproof part 21 is matched with the first foolproof part 11, the first foolproof part 11 and the second foolproof part 21 are matched, which can realize foolproof and mistake-proof assembly when the connection module and the circuit board 1 are connected, so that the plurality of signal terminals 3 in the connection module and the plurality of metal contacts 12 on the circuit board 1 are correctly connected and abutted, as shown in Figure 1 and Figure 5 .

[0052] It should be noted that the accurate connection between the signal terminal 3 in the connector and the metal contact 12 in the circuit board 1 plays a key role in ensuring the stability and integrity of signal transmission in the connector, improving the reliability of the connector, and avoiding signal attenuation or interruption caused by poor connection, and is suitable for scenarios where the signal terminal 3 and the circuit board 1 are assembled by crimping.

[0053] In some embodiments of the present application, referring to Figure 1 and Figure 2 , the first foolproof part 11 is arranged at one end of the circuit board 1 facing the connection module, and the second foolproof part 21 is arranged at one end of the connection module facing the circuit board 1. When the connection module and the circuit board 1 are docked, the docking guidance and assembly positioning between the connection modules can be achieved by cooperation of the first foolproof part 11 and the second foolproof part 21.

[0054] As a specific embodiment of the present application, the front end of the connection module is used for plugging with other electronic devices, the rear end of the connection module is used for docking with the circuit board 1, the second foolproof part 21 is arranged at the rear end of the connection module, and the first foolproof part 11 is arranged at the front end of the circuit board 1, as shown in Figure 2 .

[0055] In some embodiments of the present application, referring to Figures 1 to 4 , the first foolproof part 11 and the second foolproof part 21 are concave-convex matched, and the assembly positioning between the connection module and the circuit board 1 can be directly achieved by embedding one of the foolproof parts into the other foolproof part. The assembly process is convenient and has high accuracy, and the assembly efficiency between the connection module and the circuit board 1 can be improved.

[0056] It should be noted that the first foolproof part 11 and the second foolproof part 21 can realize foolproof assembly between the connection module and the circuit board 1 through one or more concave-convex matching areas, as long as the concave-convex matching areas of the first foolproof part 11 and the second foolproof part 21 do not affect the docking between the signal terminal 3 and the metal contact 12, the purpose of the present application can be achieved.

[0057] In some embodiments of the present application, the first foolproof part 11 and the second foolproof part 21 realize foolproof assembly between the connection module and the circuit board 1 through a single concave-convex matching area. At this time, it is preferred that the first foolproof part 11 is arranged at the front end of the circuit board 1, and the second foolproof part 21 is arranged at the side of the rear end of the connection module corresponding to the position of the first foolproof part 11, so that the circuit board 1 can only realize the concave-convex matching between the first foolproof part 11 and the second foolproof part 21 when it is placed correctly. If the circuit board 1 is turned over, the first foolproof part 11 and the second foolproof part 21 are respectively located on the left and right sides of the circuit board 1, and the assembly personnel can quickly find that there is an error in assembly.

[0058] In some other embodiments of the present application, referring toFigures 1 to 4 The first fool-proof part 11 comprises a first fool-proof groove 111 and a second fool-proof groove 112, and the second fool-proof part 21 comprises a first fool-proof block 211 and a second fool-proof block 212. The first fool-proof groove 111 is arranged to match the first fool-proof block 211, and the second fool-proof groove 112 is arranged to match the second fool-proof block 212. When the first fool-proof block 211 is embedded in the first fool-proof groove 111 and the second fool-proof block 212 is embedded in the second fool-proof groove 112, the accurate butt joint between the connection module and the circuit board 1 can be achieved.

[0059] It should be noted that the cross-sectional shape of the first fool-proof groove 111 and the second fool-proof groove 112 can be rectangular, semicircular, polygonal, etc. When the cross-sectional shapes of the first fool-proof groove 111 and the second fool-proof groove 112 are different, the first fool-proof block 211 arranged to match the first fool-proof groove 111 can only realize the concave-convex cooperation with the first fool-proof groove 111, and the second fool-proof block 212 arranged to match the second fool-proof groove 112 can only realize the concave-convex cooperation with the second fool-proof groove 112. When the cross-sectional shapes of the first fool-proof groove 111 and the second fool-proof groove 112 are the same (such as rectangular or semicircular), the cross-sectional dimensions (such as width, length or diameter) of the first fool-proof groove 111 and the second fool-proof groove 112 are different. The size difference design makes the first fool-proof groove 111 only realize the concave-convex cooperation with the first fool-proof block 211, and the second fool-proof groove 112 only realize the concave-convex cooperation with the second fool-proof block 212.

[0060] In some embodiments of the present application, please refer to Figure 2 and Figure 3 The cross-sectional shapes of the first fool-proof groove 111 and the second fool-proof groove 112 are the same, and the size of the first fool-proof groove 111 is smaller than that of the second fool-proof groove 112, so that the second fool-proof block 212 cannot be embedded in the first fool-proof groove 111, thereby realizing the corresponding cooperation of the first fool-proof groove 111 with the first fool-proof block 211 and the second fool-proof groove 112 with the second fool-proof block 212.

[0061] As a specific embodiment of the present application, please refer to Figure 2 and Figure 3 The first fool-proof groove 111 and the second fool-proof groove 112 are two open grooves arranged at one end of the substrate 13 of the circuit board 1. The cross-sectional shapes of the first fool-proof groove 111 and the second fool-proof groove 112 in the horizontal plane are both rectangular, but the cross-sectional width of the first fool-proof groove 111 is smaller than that of the second fool-proof groove 112, and / or the cross-sectional length of the first fool-proof groove 111 is smaller than that of the second fool-proof groove 112, which can realize the purpose of the present application through the size difference design.

[0062] In some embodiments of the present application, please refer to Figure 1 , Figure 3 , Figure 4 andFigure 5 The circuit board 1 is provided with a plurality of metal contacts 12, and the connecting module includes a plurality of signal terminals 3. The plurality of metal contacts 12 are arranged in one-to-one correspondence with the plurality of signal terminals 3, which can ensure that the circuit board 1 and other electronic devices or modules are stably and reliably electrically connected through the signal terminals 3, thereby reducing signal attenuation and interference in the transmission process, improving the quality of signal transmission, and facilitating high-frequency, high-speed, and high-precision signal transmission.

[0063] In some embodiments of the present application, referring to Figure 3 The first foolproof part 11 and the plurality of metal contacts 12 are arranged on the side edge of the circuit board 1 facing the connecting module. When the first foolproof part 11 and the second foolproof part 21 are docked, the metal contacts 12 on the same side as the first foolproof part 11 can also be synchronized to achieve position alignment with the plurality of signal terminals 3 in the connecting module. When the first foolproof part 11 and the second foolproof part 21 are fully matched, the tail ends of the plurality of signal terminals 3 are also in one-to-one correspondence with the plurality of metal contacts 12 on the circuit board 1.

[0064] In some embodiments of the present application, referring to Figure 7 、 Figure 8 and Figure 9 The signal terminal 3 includes a bent section 31 having a protruding portion 311 facing the metal contact 12. When the protruding portion 311 of the bent section 31 abuts against the metal contact 12 of the circuit board 1, the protruding portion 311 can be tightly abutted against the metal contact 12 by the elastic force of the bent section 31 itself, achieving self-adaptive elastic contact, avoiding separation between the tail end of the signal terminal 3 and the metal contact 12, and avoiding connection failure between the signal terminal 3 and the circuit board 1, thereby ensuring normal conduction connection of the electrical transmission and signal channel.

[0065] In some embodiments of the present application, referring to Figure 10 、 Figure 11 and Figure 12 The plurality of signal terminals 3 include a plurality of first terminals and a plurality of second terminals. The bent sections 31 of the first terminals and the bent sections 31 of the second terminals have the same structure and opposite directions, and are used to enclose a crosstalk prevention space 33 between the plurality of signal terminals 3, thereby increasing the spacing between the two rows of oppositely arranged signal terminals 3 and reducing crosstalk between adjacent signal terminals 3.

[0066] It should be noted that due to the presence of the crosstalk prevention space 33, the coupling capacitance and mutual inductance effect between adjacent first terminals and second terminals can be reduced, thereby reducing crosstalk and ensuring that the signal is not disturbed during transmission, which helps to improve the communication quality of the connector and makes it more suitable for high-precision, high-reliability, and high-frequency transmission application scenarios.

[0067] In some embodiments of the present application, please refer to Figure 10 , Figure 11 and Figure 12 , the first terminal and the second terminal have the same structure, the first terminal is arranged above the second terminal, and the tail end of the first terminal and the tail end of the second terminal are the bending section 31. The bending shape and size of the bending section 31 can be designed according to the size requirement of the anti-crosstalk space 33.

[0068] In some embodiments of the present application, please refer to Figure 9 , the signal terminal 3 includes the flat section 32 and the bending section 31, and the bending section 31 includes the inclined section 312, the horizontal section 313 and the protruding part 311 extending in the vertical direction connected in sequence, so that the anti-crosstalk space 33 is a sharp shuttle-shaped space, and the cross section of the sharp shuttle-shaped space is approximately a pentagonal structure. By adjusting the size of the sharp shuttle-shaped space, the impedance of the signal terminal 3 can be adjusted, so that the impedance matching is close to consistent, the impedance topology is basically balanced, and the signal attenuation in the signal terminal 3 is reduced.

[0069] In some embodiments of the present application, please refer to Figure 7 and Figures 10 to 14 , the connection module further includes the first shielding member 4, and the plurality of signal terminals 3 are arranged on both sides of the first shielding member 4, and part of the first shielding member 4 extends into the anti-crosstalk space 33. The crosstalk electromagnetic waves between the first terminal and the second terminal can be shielded, and the crosstalk electromagnetic waves in the anti-crosstalk space 33 can be absorbed, so as to ensure fast, smooth and balanced signal transmission.

[0070] In some embodiments of the present application, please refer to Figure 11 and Figure 14 , the first shielding member 4 includes the plate-shaped part 42 and the tubular part 41, wherein the plate-shaped part 42 is arranged corresponding to the flat section 32 of the signal terminal 3, and the tubular part 41 is arranged corresponding to the bending section 31 of the signal terminal 3. The distance between the metal plate of the tubular part 41 and the bending section 31 is shortened, so that the absorption effect of the tail end of the first shielding member 4 on the crosstalk electromagnetic waves in the anti-crosstalk space 33 is improved.

[0071] It should be noted that the cross-sectional shape and size of the tubular part 41 can be set according to the requirement of impedance matching. The cross section of the tubular part 41 can be polygonal, circular or elliptical, etc. The tubular part 41 can also be embedded in the insulating tube 23 of the insulating main body 2. As long as the absorption of the crosstalk electromagnetic waves in the anti-crosstalk space 33 can be realized, the purpose of the present application can be achieved.

[0072] In some embodiments of the present application, please refer to Figure 10 , Figure 11 and Figure 14The first shielding member 4 is further provided with a connecting portion 43 for abutting against the inner wall of the metal shell 7, and the connecting portion 43 is exposed outside the insulating body 2 when the first shielding member 4 is assembled with the insulating body 2, so that the electrical connection between the connecting portion 43 and the inner wall of the metal shell 7 is achieved by abutting, thereby realizing the ground of the crosstalk electromagnetic wave. The connecting portion 43 can be arranged on one side or both sides of the first shielding member 4, and both can achieve the purpose of the present application.

[0073] In some embodiments of the present application, referring to Figure 7 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 , the connection module further comprises a second shielding member 5 and a third shielding member 6, which are arranged on the outer sides of the plurality of signal terminals 3, respectively, for electrical connection with the metal shell 7 of the connector, so that the second shielding member 5 and the third shielding member 6 have the same potential as the metal shell 7, and can shield the crosstalk electromagnetic wave outside the crosstalk prevention space 33, avoiding the introduction of external crosstalk into the signal terminals 3 by the metal shell 7.

[0074] In some embodiments of the present application, referring to Figure 12 and Figure 13 , the shapes of the first shielding member 4, the second shielding member 5 and the third shielding member 6 match the shape of the plurality of signal terminals 3, so that the appropriate spacing between the signal terminals 3 and the shielding members can be maintained, and the shielding effect can be improved.

[0075] Specifically, the shape of the tubular portion 41 matches the shape of the crosstalk prevention space 33, so that the spacing between the outer wall of the tubular portion 41 and the plate body of the opposite bending section 31 is the same or approximately the same. The tubular portion 41 can uniformly absorb crosstalk electromagnetic waves in all directions around the bending section 31, which is beneficial to improve the shielding effect of the tubular portion 41 on the crosstalk prevention space 33.

[0076] The second shielding member 5 and the third shielding member 6 have the same structure and opposite directions. The second shielding member 5 comprises a third plate body 53, a second plate body 52 and a first plate body 51 connected in sequence. The combination of the second shielding member 5 and the third shielding member 6 forms a sharp shuttle-shaped bidirectional signal protection structure matching the crosstalk prevention space 33, which can avoid the discontinuity of the signal terminal 3 loop and completely shield the external crosstalk electromagnetic wave, so as to ensure fast, smooth and balanced signal transmission.

[0077] In some embodiments of the present application, referring to Figure 7 and Figure 13The first shielding member 4, the second shielding member 5, the third shielding member 6 and the plurality of signal terminals 3 are embedded in the insulating block 22 of the insulating body 2, so as to realize the fixed arrangement of the first shielding member 4, the second shielding member 5, the third shielding member 6 and the plurality of signal terminals 3 in the connecting module.

[0078] In some embodiments of the present application, referring to Figure 3 and Figure 7 The connecting module further comprises the insulating body 2, and part of the insulating body 2 is configured as the second fool-proof part 21. The second fool-proof part 21 can have an insulating property, so as to avoid unnecessary electrical connection when the second fool-proof part 21 cooperates with the first fool-proof part 11 on the circuit board 1.

[0079] In some embodiments of the present application, referring to Figure 3 , Figure 4 and Figure 6 The connecting module further comprises the metal shell 7, and the circuit board 1 is provided with the grounding contact 14 corresponding to the metal shell 7. When the connecting module is docked with the circuit board 1, the metal shell 7 also abuts against the grounding contact 14 on the circuit board 1, so as to form a grounding loop.

[0080] Referring to Figures 1 to 14 In some embodiments of the present application, the docking method of the above connector is as follows:

[0081] Step one: after the connecting module and the circuit board 1 are respectively completed, the first fool-proof groove 111 is aligned with the first fool-proof block 211, and the second fool-proof groove 112 is aligned with the second fool-proof block 212;

[0082] Step two: the first fool-proof block 211 is clamped into the first fool-proof groove 111, and the second fool-proof block 212 is clamped into the fool-proof groove, so as to realize the position correspondence between the plurality of signal terminals 3 and the plurality of metal contacts 12, and realize the position correspondence between the metal shell and the grounding contact 14;
