Connector

Abstract

The embodiment of the utility model discloses a connector which can be respectively connected with a plurality of contacts by utilizing a plurality of conductive arms arranged on a terminal strip. Meanwhile, the limiting surface abuts against the deformation section of the conductive arm so as to limit the bending amplitude of the conductive arm. Therefore, the contact surface is arranged in the plugging channel and faces the jack, and when the plug connector is plugged into the plugging channel, the plug connector can abut against the contact surface, and then the limiting surface is pushed to slide along the deformation section, so that the electric contact area can directly abut against the contact. The friction between the electric contact area and the plug connector is reduced, and the service life of the electric contact area and the contact is prolonged. Foreign matters are prevented from being adhered to the surface of the electric contact area in multiple times of friction. And on the other hand, the bending amount of the conductive arm can be adjusted by utilizing the position change of the limiting surface on the deformation section, so that the pressure applied to the contact by the electric contact area can be better controlled, and the stability of electric connection is ensured.

Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, in particular to a connector. Background Art

[0002] Connectors are used to connect electrical devices or electrical components. When connected, the connection terminals of the connector will abut against the contacts to achieve electrical contact between the two. Therefore, the performance of the connection terminals will have a direct impact on the transmitted electrical signals or electrical energy. During the use of the connector, the connection terminals will produce friction with the plug-in parts, which will cause greater wear on the connection terminals. At the same time, foreign matter will adhere to the electrical contact surface of the connection terminals during friction, making the electrical connection unstable. How to improve the service life of the connection terminals and increase the stability of the connection has become a problem that needs to be solved. Utility Model Content

[0102] In some embodiments, Figure 1-Figure 2 As shown, the connector in this embodiment includes a trigger portion 1 , a shell portion 2 and a terminal block 3 .

[0103] Further reference Figure 3 , Figure 4 and Fig.11 As shown, the shell 2 has a plug-in channel 21. The plug-in channel 21 has a socket 211. The socket 211 is located at one end of the plug-in channel 21. The plug-in connector 8 can be inserted into the plug-in channel 21 through the socket 211. Thus, the plug-in connector 8 is mechanically connected to the connector.

[0104] Meanwhile, the trigger part 1 includes a limit push block 11. The limit push block 11 has a limit surface 111 and a contact surface 112. At least a part of the contact surface 112 is located in the insertion channel 21, and the contact surface 112 faces the socket 211. The trigger part 1 in this embodiment can slide along the insertion channel 21, so that the contact surface 112 is close to or away from the socket 211.

[0105] Further reference Figure 5-Figure 9 As shown, the terminal block 3 includes a plurality of conductive arms 31. The conductive arm 31 includes a deformation section 311 and an electrical contact area 312 in the length direction. The electrical contact area 312 is located between the deformation section 311 and the socket 211. That is, the conductive arm 31 extends toward the socket 211, and the deformation section 311 and the electrical contact area 312 are sequentially arranged along the extension direction of the conductive arm 31.

[0106] At the same time, the limiting surface 111 in this embodiment is in abutment with each deformation segment 311 of the plurality of conductive arms 31 .

[0107] Specifically, Figure 1 As shown, the insertion channel 21 includes two flat side walls and two curved side walls, and the two flat side walls are connected between the two curved side walls, so that the insertion port 211 is in the shape of a racetrack. Figure 7 As shown, the limiting surface 111 in this embodiment abuts against the side of the deformation section 311 away from the flat side wall, and causes the deformation section 311 to generate an elastic bending amount toward the flat side wall.

[0108] Further reference Fig.11 As shown, when the connector 8 is inserted from the socket 211 into the plug channel 21 (as shown in state I), the connector 8 will abut against the contact surface 112, thereby pushing the limit push block 11 to move to the inner side of the plug channel 21 (that is, away from the end of the socket 211). In this form, the limit surface 111 will slide along the length direction of the deformation section 311. During this process, the length of the area between the contact surface 112 and the socket 211 of the deformation section 311 will gradually increase. This makes this part of the deformation section 311 bend and deform toward the connector 8 without the limit of the limit surface 111, thereby driving the electrical contact area 312 away from the side wall of the plug channel 21, that is, close to the contact 81 of the connector 8. When the connector 8 is inserted a predetermined distance, the electrical contact area 312 will abut against the contact 81. Thereby, the electrical connection between the connector and the connector 8 is achieved.

[0109] In summary, the connector of this embodiment utilizes a plurality of conductive arms 31 disposed on the terminal row 3, so that the connector can be connected to a plurality of contacts 81 respectively, and the limiting surface 111 is abutted against the deformation section 311 of the conductive arm 31 to limit the bending amplitude of the conductive arm 31. Thus, the contact surface 112 is disposed in the plug channel 21 and faces the socket 211. When the plug connector 8 is inserted into the plug channel 21, it will abut against the contact surface 112, thereby pushing the limiting surface 111 to slide along the deformation section 311, so that the electrical contact area 312 can be directly pressed against the contact 81. The friction between the electrical contact area 312 and the plug connector 8 is reduced, and the service life of the electrical contact area 312 and the contact 81 is increased. Foreign matter is prevented from adhering to the surface of the electrical contact area 312 during multiple frictions. On the other hand, by utilizing the change in the position of the limiting surface 111 on the deformation section 311 , the bending amount of the conductive arm 31 can be adjusted, thereby better controlling the pressure applied by the electrical contact area 312 to the contact point 81 to ensure the stability of the electrical connection.

[0110] In some embodiments, Figure 5 and Fig.10 As shown, the limiting push block 11 has a plurality of first guide grooves 113. The first guide grooves 113 extend toward the side wall of the plug-in channel 21 and along the axial direction of the plug-in channel 21, and the bottom of the first guide grooves 113 forms the above-mentioned limiting surface 111. At the same time, the plurality of conductive arms 31 pass through the plurality of first guide grooves 113 in a one-to-one correspondence, and the plurality of conductive arms 31 extend toward the socket 211.

[0111] In this embodiment, the width of the first guide groove 113 is configured to be slightly larger than the width of the conductive arm 31. When the trigger part 1 is driven by the plug-in connector 8 to slide along the axial direction of the plug-in channel 21, the first guide groove 113 can limit the deformation direction of the conductive arm 31, so that the conductive arm 31 opens or closes along the radial direction of the plug-in channel 21. The conductive arm 31 is prevented from swinging in the length direction of the flat side wall, ensuring that the electrical contact areas 312 on the multiple conductive arms 31 can accurately abut against the multiple contacts 81 of the plug-in connector 8.

[0112] In some embodiments, Figure 7-Figure 10 As shown, the limiting push block 11 in this embodiment has a guide arc surface 114. The guide arc surface 114 extends from the limiting surface 111 to the contact surface 112, and the guide arc surface 114 is bent toward the side of the limiting push block 11.

[0113] When the contact surface 112 moves toward the electrical contact area 312 , the guiding arc surface 114 slides along the deformation segment 311 and presses the deformation segment 311 toward the side wall of the insertion channel 21 .

[0114] Specifically, the limiting surface 111 and the contact surface 112 in this embodiment are both planes and perpendicular to each other, and the guide arc surface 114 is located between the limiting surface 111 and the contact surface 112, and extends along the length direction of the contact surface 112. At the same time, when the deformation segment 311 is in a free state, the deformation segment 311 bends toward the area between the two flat side walls, so that part of the deformation segment 311 is opposite to the contact surface 112.

[0115] When the limiting push block 11 approaches or moves away from the socket 211, the guide arc surface 114 in this embodiment can guide the deformation section 311 to open and deform toward the flat side wall, or to collapse and deform toward the inner side of the insertion channel 21. In addition, the edge of the limiting push block 11 between the limiting surface 111 and the contact surface 112 is prevented from scratching the deformation section 311.

[0116] In some embodiments, Figure 4-Figure 9 As shown, the triggering part 1 further includes a plurality of retaining walls 12. The plurality of retaining walls 12 are arranged at intervals and protrude from the limiting surface 111, and the opposite sides of two adjacent retaining walls 12 and the limiting surface 111 form a first guide groove 113.

[0117] Further reference Fig.10 As shown, the shell 2 includes a plurality of stop bars 22. The plurality of stop bars 22 correspond to the plurality of stop walls 12 one by one and extend along the axial direction of the insertion channel 21. The opposite sides of two adjacent stop bars 22 and the inner wall of the insertion channel 21 form a second guide groove 23.

[0118] When the contact surface 112 approaches the electrical contact area 312 , the first guide groove 113 and the second guide groove 23 are engaged with each other to form an accommodating channel 4 , and the deformable section 311 passes through the accommodating channel 4 .

[0119] As a result, at least a portion of the deformation section 311 can be accommodated in the accommodating channel 4, ensuring that during the bending of the conductive arm 31, the multiple electrical contact areas 312 can correspond one-to-one with the multiple contacts 81, thereby limiting the shape of the deformation section 311 before and after deformation to the greatest extent.

[0120] In some embodiments, Figure 5 As shown, in this embodiment, the limit push block 11 has two limit surfaces 111, and the two limit surfaces 111 are away from each other. The plurality of conductive arms 31 include a plurality of first conductive arms 313 and a plurality of second conductive arms 314. The first conductive arms 313 and the second conductive arms 314 are respectively arranged corresponding to the two limit surfaces 111.

[0121] Further reference Figure 8 and Fig. 9 As shown, the retaining wall 12 has a first positioning surface 121 , and the retaining bar 22 has a second positioning surface 221 opposite to the first positioning surface 121 .

[0122] When the contact surface 112 approaches the electrical contact area 312, the first positioning surface 121 abuts against the second positioning surface 221 and slides along the second positioning surface 221, and the limit push block 11 is sandwiched between the deformation sections 311 of the first conductive arm 313 and the second conductive arm 314. That is, the first conductive arm 313 and the second conductive arm 314 abut against both sides of the limit push block 11 through the deformation section 311. At the same time, the deformation section 311 is spaced apart from the bottom of the second guide groove 23 (such as Fig.10 (shown in region III).

[0123] Specifically, the first positioning surface 121 and the second positioning surface 221 in this embodiment are both rectangular surfaces, and the length of the first positioning surface 121 is less than the length of the second positioning surface 221. During the axial movement of the trigger portion 1 along the insertion channel 21, the first positioning surface 121 slides on the second positioning surface 221, and at the same time, the first guide groove 113 and each area of ​​the second guide groove 23 sequentially form an accommodating channel 4. Therefore, each area of ​​the deformation section 311 sequentially passes through the accommodating channel 4.

[0124] In this form, on the one hand, by using the cooperation of the stop bars 22 protruding from the two flat side walls and the stop walls 12 protruding from the two limit surfaces 111, the position accuracy of the limit push block 11 between the two flat side walls can be limited to prevent the limit push block 11 from shaking up and down. On the other hand, the deformation sections 311 of the first conductive arm 313 and the second conductive arm 314 can be attached to both sides of the limit push block 11. Furthermore, the limit push block 11 is used to further ensure the shape of the first conductive arm 313 and the second conductive arm 314 before and after deformation, especially when the number of conductive arms 31 is large, it can ensure that multiple conductive arms 31 are deformed synchronously. On the other hand, the first conductive arm 313 and the second conductive arm 314 do not contact the bottom of the second guide groove 23, thereby limiting the positive pressure applied by the deformation section 311 to the limit surface 111, avoiding excessive friction between the two, so that the limit push block 11 can be driven more easily.

[0125] In some embodiments, Figure 2-Figure 3 As shown, the connector further includes two reset parts 5. The reset part 5 includes a push rod 51, and the two push rods 51 are symmetrically arranged on both sides of the limit push block 11. The reset part 5 pushes the trigger part 1 to move toward the socket 211 through the push rod 51.

[0126] In this embodiment, the reset portion 5 allows the contact surface 112 to move toward the socket 211 again after the connector 8 is pulled out from the insertion channel 21, so as to facilitate the reinsertion of the connector 8. At the same time, when the connector 8 is pulled out, the limit push block 11 moves toward the socket 211 under the drive of the push rod 51, so that the first conductive arm 313 and the second conductive arm 314 can be opened again, further protecting the electrical contact area 312 from scratches.

[0127] In some embodiments, Figure 4 As shown, the triggering part 1 further includes two driving blocks 13 corresponding to the two resetting parts 5 . The limiting push block 11 is located between the two driving blocks 13 .

[0128] Further reference Figure 2-Figure 3 As shown, the reset part 5 in this embodiment further includes a sleeve 52 and an elastic member 53. The elastic member 53 is disposed in the sleeve 52. One end of the push rod 51 is telescopically disposed in the sleeve 52 and abuts against the elastic member 53, and the other end abuts against the corresponding driving block 13. The trigger part 1 compresses the elastic member 53 through the push rod 51, and the elastic member 53 generates a reset elastic force. The elastic member 53 may be a compression spring.

[0129] Specifically, the elastic force of the elastic member 53 is configured to be greater than the friction between the deformation section 311 and the limiting surface 111, ensuring that the elastic force of the elastic member 53 can push the trigger part 1 toward the socket 211, so that the contact surface 112 can be reset in time after the connector 8 is pulled out.

[0130] Optionally, the reset portion 5 in this embodiment may be a spring pin, the ejector pin of which is used to form the push rod 51. Thus, the reset portion 5 is made more compact as a whole, and the manufacturing cost of the connector is reduced.

[0131] In some embodiments, Figure 3 As shown, the shell 2 further has two fixing holes 27 , and the plug-in channel 21 is located between the two fixing holes 27 .

[0132] The two sleeves 52 are respectively disposed in the two fixing holes 27 , and the ends of the push rod 51 extend out of the fixing holes 27 .

[0133] The two fixing holes 27 in this embodiment can stably fix the sleeve 52 to the shell 2 , while ensuring that the push rod 51 can extend from the fixing hole 27 to abut against the driving block 13 .

[0134] In some embodiments, Figure 4 As shown, the triggering part 1 further includes two positioning blocks 14 . The two positioning blocks 14 are located on both sides of the limiting push block 11 , and the two positioning blocks 14 are arranged between the two driving blocks 13 .

[0135] Further reference Figure 3 and Figure 8 As shown, the shell 2 has two guide windows 24 corresponding to the two positioning blocks 14 . The two guide windows 24 penetrate the side wall of the plug-in channel 21 and have two guide surfaces 241 arranged opposite to each other. The two guide surfaces 241 extend along the axial direction of the plug-in channel 21 .

[0136] The two driving blocks 13 pass through the two guide windows 24 respectively and extend toward the two sides of the insertion channel 21 , and the positioning block 14 is slidably disposed between the two corresponding guide surfaces 241 .

[0137] The two guide surfaces 241 in this embodiment are used to guide the movement of the positioning block 14, especially when the length of the limit push block 11 is large, the stability of the movement of the trigger part 1 can be improved. The limit push block 11 is located in the middle of the two flat side walls, which further ensures that the bending amplitudes of the first conductive arm 313 and the second conductive arm 314 are the same.

[0138] In some embodiments, Figure 3-Figure 4 As shown, the guide window 24 has a third positioning surface 242 . The direction of the third positioning surface 242 is opposite to the direction of the insertion opening 211 .

[0139] When the trigger part 1 moves toward the socket 211, when the positioning block 14 abuts against the third positioning surface 242, the contact surface 112 and the socket 211 have a predetermined distance (eg, Fig.11Thus, it is ensured that the electrical contact area 312 can be accurately pressed against the contact point 81 each time the plug connector 8 is inserted.

[0140] In some embodiments, Figure 5-Figure 8 As shown, the positioning block 14 defines a position-avoiding hole 141 , and the position-avoiding hole 141 penetrates the positioning block 14 along the axial direction of the insertion channel 21 .

[0141] The connector further includes a limiting portion 6. The limiting portion 6 includes two limiting arms 61, and the limiting arms 61 have hooks 611. The two hooks 611 respectively pass through the two avoiding holes 141 and extend into the plug-in channel 21, and are bent toward opposite sides.

[0142] The hook 611 in this embodiment is used to be clamped on the side of the plug connector 8. When the electrical contact area 312 abuts against the contact point 81, the two hooks 611 can locate the position of the plug connector 8 to prevent the plug connector 8 from moving. At the same time, it can also further prevent the electrical contact area 312 from loosening the contact with the contact point 81.

[0143] In some embodiments, Figure 4 As shown, the shell 2 has two avoidance grooves 25, which correspond to two hooks 611 respectively, and the contact surface 112 is located between the two limit arms 61. When the two limit arms 61 generate elastic bending away from each other, at least part of the hook 611 moves into the corresponding avoidance groove 25.

[0144] The avoidance groove 25 in this embodiment is arranged on the curved side wall, and the avoidance groove 25 is used to avoid the hook 611. When the connector is inserted into the plug channel 21, the plug connector 8 pushes the hook 611 toward the curved side wall, and then the hook 611 is clamped on both sides of the plug connector 8. In this process, the avoidance groove 25 can ensure that the limit arm 61 has sufficient deformation space.

[0145] In some embodiments, Figure 3 and- Figure 7 As shown, the shell 2 is provided with an escape window 26 , which is recessed from the inner wall of the plug-in channel 21 toward the outside, and the length direction of the escape window 26 is consistent with the arrangement direction of the plurality of stop bars 22 .

[0146] The conductive arm 31 further includes a curved section 315 in the length direction, and the curved section 315 is arranged near the end of the conductive arm 31. The curved section 315 is curved toward the side wall away from the plug-in channel 21 and forms an electrical contact area 312. The electrical contact area 312 located at the curved section 315 is an arc surface, which is curved toward the plug-in component 8 so as to abut against the contact 81.

[0147] Further reference Fig. 9As shown, during the process of the deformation section 311 bending and deforming toward the side wall of the plug-in channel 21 , the end of the conductive arm 31 extends into the avoidance window 26 .

[0148] Specifically, Figure 7 As shown, in this embodiment, the shell 2 further includes a latch 28. The latch 28 is disposed inside the insertion channel 21 and extends away from the socket 211. The latch 28 abuts against the end of the conductive arm 31 to prevent the first conductive arm 313 and the second conductive arm 314 from being too close.

[0149] In contrast, when the deformation section 311 bends toward the flat side wall, the end of the conductive arm 31 can enter the avoidance window 26, thereby preventing the conductive arm 31 from being driven by the limiting push block 11, causing the first conductive arm 313 and the second conductive arm 314 to be too far apart, resulting in interference with the plug-in channel 21.

[0150] In some embodiments, Figure 7 and Fig. 9 As shown, a plurality of stop bars 22 extend in parallel and pass through the avoidance window 26 along the width direction of the avoidance window 26 .

[0151] The deformation section 311 is arranged in a free state, tilted from the limiting surface 111 toward the middle of the plug-in channel 21. When the deformation section 311 is deformed to open toward the flat side wall, at least part of the end of the conductive arm 31 is located between the stop bars 22.

[0152] That is, if Fig.11 As shown in state I, the first conductive arm 313 and the second conductive arm 314 are in a state of being away from each other, and most of their areas are located between the two stop bars 22, and only the electrical contact area 312 is located outside the second guide groove 23. When the electrical contact area 312 abuts against the contact point 81 (as shown in FIG. Fig.11 When the end of the conductive arm 31 overlaps the tongue 28, the end of the conductive arm 31 is still located between the two stop bars 22. Thus, the stop bars 22 can maximize the movement of the conductive arm 31 along the plane perpendicular to the flat side wall.

[0153] In some embodiments, Figure 3-Figure 4 As shown, the avoidance window 26 passes through the plug-in channel 21. The connector also includes an insulating patch 7. The insulating patch 7 may be made of foam. Thus, by sealing the insulating patch 7 on the outside of the avoidance window 26, it is possible to prevent the end of the conductive arm 31 from leaking electricity when the connector is connected to the plug-in connector 8. At the same time, when the connector is powered (without the plug-in connector 8), the insulating patch 7 is uncovered, and the end of the conductive arm 31 located in the avoidance window 26 is abutted by a test tool, so that the on-off status of each conductive arm 31 can be detected.

[0154] In some embodiments, Figure 3 As shown, the conductive arm 31 further includes a fixed section 316 in the length direction. The deformable section 311 is located between the fixed section 316 and the electrical contact area 312. The deformable section 311 is inclined toward the center direction of the socket 211 in a free state.

[0155] Further reference Figure 5 As shown, the terminal block 3 further includes a mounting frame 32. The mounting frame 32 has a plurality of mounting holes 321, and the plurality of conductive arms 31 are respectively disposed in the plurality of mounting holes 321 through the fixing sections 316.

[0156] The fixing section 316 in this embodiment is passed through the mounting hole 321 , thereby fixing the conductive arm 31 and preventing the limiting surface 111 from driving the conductive arm 31 to move during the movement of the limiting push block 11 .

[0157] In some embodiments, Figure 5-Figure 6 As shown, the limiting portion 6 further includes a fixing plate 62 , and the fixing plate 62 has a plurality of positioning holes 621 .

[0158] The mounting frame 32 includes a first frame body 322 and a second frame body 323 arranged in pairs. The first frame body 322 and the second frame body 323 each have a plurality of mounting holes 321, a mounting surface 324 and a positioning boss 325, and the mounting surface 324 and the positioning boss 325 are located on opposite sides of the first frame body 322 and the second frame body 323.

[0159] The two mounting surfaces 324 are respectively fitted with the two plate surfaces of the fixing plate 62 . The positioning bosses 325 of the first frame 322 and the second frame 323 are respectively inserted into different positioning holes 621 . The two limiting arms 61 are located at both sides of the mounting frame 32 .

[0160] In this embodiment, two mounting surfaces 324 are used to clamp on both sides of the fixed plate 62 to limit the position of the limiting part 6 in the thickness direction of the fixed plate 62. At the same time, the positioning boss 325 of the first frame 322 cooperates with part of the positioning hole 621 to limit the horizontal position of the first frame 322 and the fixed plate 62. And the positioning boss 325 of the second frame 323 cooperates with the remaining positioning holes 621 to further limit the relative position of the first frame 322 and the second frame 323. As a result, a connection portion is formed between the terminal row 3 and the limiting part 6. The connection portion can be fixedly connected to the shell 2 after assembly. On the other hand, the limiting arm 61, the plurality of first conductive arms 313 and the plurality of second conductive arms 314 have a high position accuracy to avoid the position of the limiting arm 61 and the conductive arm 31 from changing during the multiple plugging and unplugging of the plug connector 8. On the other hand, the limiting arm 61 is arranged on both sides of the mounting frame 32 to ensure that the limiting arm 61 has sufficient elastic deformation.

[0161] Furthermore, if Figure 6 As shown, a slot 326 is provided on the opposite side of the first frame 322 and the second frame 323, and a lug 622 is provided on the fixing plate 62. The positioning hole 621 is provided on the lug 622. When the fixing plate 62 is clamped between the first frame 322 and the second frame 323, the lug 622 is clamped in the slot 326, further limiting the relative position between the limiting portion 6 and the resetting portion 5.

[0162] In an optional implementation, the connector in the above embodiment can be applied to a connection component, which includes a wire and the above connector connected to the end of the wire, and the connection component can be used to connect an electronic device. For example, the terminal row 3 of the connector is configured as a Type-C interface type. As a result, the service life of the connection component is improved, especially in scenarios with a high number of plug-in and unplug times (such as shared power banks), which can reduce the maintenance cost of the equipment.

[0163] In summary, the connection assembly of this embodiment utilizes a plurality of conductive arms 31 disposed on the terminal row 3, so that the connector can be connected to a plurality of contacts 81 respectively, and the limiting surface 111 is abutted against the deformation section 311 of the conductive arm 31 to limit the bending amplitude of the conductive arm 31. Thus, the contact surface 112 is disposed in the plug channel 21 and faces the socket 211. When the plug connector 8 is inserted into the plug channel 21, it will abut against the contact surface 112, thereby pushing the limiting surface 111 to slide along the deformation section 311, so that the electrical contact area 312 can be directly pressed against the contact 81. The friction between the electrical contact area 312 and the plug connector 8 is reduced, and the service life of the Enjoy Power Bank is increased. It can also prevent foreign matter from adhering to the surface of the electrical contact area 312 during multiple frictions.

[0164] In another optional implementation, the connector in the above embodiment can be applied to a test fixture. The terminal row 3 of the connector is connected to the control circuit of the test fixture. The terminal row 3 of the connector can be adjusted according to the interface form of the test product. When the test products of the same batch pass through the test fixture in sequence, each test product will be connected to the connector of the test fixture.

[0165] In summary, the test fixture of this embodiment utilizes a plurality of conductive arms 31 disposed on the terminal block 3 so that the connector can be connected to a plurality of contacts 81 respectively, and the limiting surface 111 is abutted against the deformation section 311 of the conductive arm 31 to limit the bending amplitude of the conductive arm 31. Thus, the contact surface 112 is disposed in the plug channel 21 and faces the socket 211. When the plug connector 8 is inserted into the plug channel 21, it will abut against the contact surface 112, thereby pushing the limiting surface 111 to slide along the deformation section 311, so that the electrical contact area 312 can be directly pressed against the contact 81. During the frequent plugging and unplugging operations between the test product and the connector, the friction between the electrical contact area 312 and the plug connector 8 is reduced, and at the same time, the service life of the test fixture is increased. Avoid foreign matter adhering to the surface of the electrical contact area 312 during multiple frictions.
