Description

Technical Field

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

[0082] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the detailed description of the present invention below, some specific details are described in detail. For those skilled in the art, the present invention can be fully understood without the description of these details. In order to avoid confusing the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0083] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0084] Unless the context clearly requires otherwise, the words "include", "comprising" and similar words throughout the application should be interpreted as including rather than exclusive or exhaustive; that is, the meaning is "including but not limited to".

[0085] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0086] Unless otherwise clearly defined and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0087] For ease of explanation, spatially relative terms such as "inside", "outside", "below", "below", "lower", "above", "upper", etc. are used herein to describe the relationship of one element or feature illustrated in the figures to another element or feature. It will be understood that spatially relative terms may be intended to include different orientations of the device in use or operation other than the orientation depicted in the figures.

[0090] Figure 5 3 is an exploded schematic diagram of the driving clamp 3 and the elastic member 4 of this embodiment. The driving clamp 3 in the figure includes an inlay 33 , a part of which is exposed to the outside of the mounting frame 31 .

[0091] Figure 6 2 is a cross-sectional view of the shell 5 of this embodiment. The insertion channel 521 and the accommodating channel 511 in the figure extend in the same direction.

[0092] Figure 7 and Figure 8Schematic diagram of the structure of the first conductive arm 1 and the shell 5 of this embodiment.

[0093] Fig. 9 1 is a schematic diagram of the working state of the connector of this embodiment. In state I, the first conductive arm 1 and the second conductive arm 2 are in an open state. In state II, the first conductive arm 1 and the second conductive arm 2 are in a retracted state. The figure uses dot-dash lines to show the plug-in connector 8, which is provided with a contact 81. When the tail of the plug-in connector 8 abuts against the socket 5212, the contact 81 just corresponds to the electrical contact area 12.

[0094] In some embodiments, Figure 1-Figure 2 As shown, the connector in this embodiment includes a plurality of first conductive arms 1 , a plurality of second conductive arms 2 , a driving clamp 3 , and an elastic member 4 disposed on the driving clamp 3 .

[0095] Further reference Figure 3-Figure 5 As shown, the driving clamp 3 includes two mounting frames 31 and a rotating shaft 32. The two mounting frames 31 are rotatably connected through the rotating shaft 32, and the mounting frame 31 includes a clamp head 311 and a positioning portion 312. The positioning portion 312 is located at the opposite side of the two clamp heads 311, and the elastic member 4 is arranged on the driving clamp 3.

[0096] Specifically, the mounting frame 31 in this embodiment includes positioning platforms, and two positioning platforms are protrudingly disposed on opposite sides of the two mounting frames 31. The surface of the positioning platform forms the positioning portion 312.

[0097] A plurality of first conductive arms 1 are arranged on one mounting frame 31 to form a first terminal row. A plurality of second conductive arms 2 are arranged on another mounting frame 31 to form a second terminal row. At the same time, one end of the first conductive arm 1 and one end of the second conductive arm 2 extend from two clamps 311 respectively. Thus, when the two clamps 311 approach or move away from each other, the two clamps 311 can drive the first conductive arm 1 and the second conductive arm 2 to swing.

[0098] When the elastic member 4 drives the two mounting frames 31 to rotate, the two clamps 311 drive the first conductive arm 1 and the second conductive arm 2 to approach each other until the two positioning portions 312 abut against each other. That is, the elastic member 4 drives the two clamps 311 to approach each other, and the first conductive arm 1 and the second conductive arm 2 approach each other under the drive of the two clamps 311. When the two positioning portions 312 abut against each other, the positions of the first conductive arm 1 and the second conductive arm 2 can be limited.

[0099] Optionally, the elastic member 4 in this embodiment can be a compression spring or a torsion spring. When the elastic member 4 is configured as a torsion spring, the torsion spring can be sleeved on the rotating shaft 32, and the two driving arms of the torsion spring are respectively abutted on the two mounting frames 31, so that the torsion spring drives the two mounting frames 31 to rotate along the rotating shaft 32 through the swing of the two driving arms. When the elastic member 4 is a compression spring, the elastic member 4 can abut on the two mounting frames 31, so that the elastic force of the elastic member 4 drives the two clamps 311 to approach each other. And further ensure the stability of the first conductive arm 1 and the second conductive arm 2 in contact with the contact 81.

[0100] In summary, in the connector of this embodiment, the elastic member 4 is arranged on the driving clamp 3, and the two mounting frames 31 of the driving clamp 3 are configured to rotate relative to each other through the rotating shaft 32. The first conductive arm 1 and the second conductive arm 2 are respectively arranged on the two mounting frames 31, and the ends of the first conductive arm 1 and the second conductive arm 2 are extended from the clamp 311. Therefore, when the two clamps 311 are driven away from each other, the first conductive arm 1 and the second conductive arm 2 are opened at a predetermined angle, so that the plug-in component 8 can be inserted between the first conductive arm 1 and the second conductive arm 2. In this process, friction between the first conductive arm 1 and the second conductive arm 2 and the plug-in component 8 can be avoided. The service life of the first conductive arm 1 and the second conductive arm 2 is improved, and foreign matter can be prevented from adhering to the surface of the first conductive arm 1 and the second conductive arm 2 during multiple frictions.

[0101] On the other hand, when the two clamps 311 are not driven, the elastic member 4 drives the two clamps 311 to approach each other, and the first conductive arm 1 and the second conductive arm 2 can move toward the contact 81 of the connector to electrically connect the connector to the plug-in component 8. In this process, the two positioning parts 312 are used for limiting, which can ensure that the first conductive arm 1 and the second conductive arm 2 are stably connected to the contact 81, and can also avoid excessive pressure between the first conductive arm 1 and the second conductive arm 2 and the contact 81, so as to further protect the contact 81 and the first conductive arm 1 and the second conductive arm 2.

[0102] In some embodiments, Figure 3-Figure 5 As shown, the elastic member 4 is a compression spring and abuts between the two mounting frames 31. The mounting frame 31 has a driving surface 313, and the rotating shaft 32 is located between the driving surface 313 and the positioning portion 312. The driving surfaces 313 of the two mounting frames 31 are arranged away from each other. When the two driving surfaces 313 approach each other, the elastic member 4 generates a restoring elastic force.

[0103] In this embodiment, the operator or the driving mechanism can drive the two driving surfaces 313 to open the two clamps 311 to ensure that the connector 8 can be inserted between the first conductive arm 1 and the second conductive arm 2. Thus, the driving operation of the connector is simplified.

[0104] In some embodiments, Figure 3-Figure 5 As shown, there are multiple compression springs. The mounting frame 31 has multiple accommodating grooves 314 corresponding to the multiple compression springs, and the multiple accommodating grooves 314 of the two mounting frames 31 are arranged opposite to each other. That is, the multiple accommodating grooves 314 of the two mounting frames 31 are arranged corresponding to each other. At the same time, the two ends of the compression spring extend into the corresponding accommodating grooves 314 respectively and abut against the bottom of the accommodating grooves 314.

[0105] In this embodiment, the accommodating groove 314 is used to stably restrict the elastic member 4 between the two mounting frames 31 to prevent the elastic member 4 from bouncing away from between the two mounting frames 31 when the two driving ends 315 approach each other.

[0106] In some embodiments, Figure 5 As shown, the mounting frame 31 further includes a driving end 315 and a plurality of mounting holes 316. The mounting holes 316 penetrate the mounting frame 31 and extend from the clamping head 311 to the driving end 315. The driving surface 313 in the above embodiment is disposed at the driving end 315.

[0107] Further reference Figure 3-Figure 4 As shown, a plurality of first conductive arms 1 and a plurality of second conductive arms 2 are respectively disposed in a plurality of mounting holes 316 , and both ends of the first conductive arms 1 and the second conductive arms 2 extend out of the mounting holes 316 .

[0108] The mounting hole 316 in this embodiment is used to stably mount the first conductive arm 1 and the second conductive arm 2 together with the mounting frame 31, so as to prevent the first conductive arm 1 and the second conductive arm 2 from shaking during the movement of the two clamps 311. At the same time, part of the first conductive arm 1 and part of the second conductive arm 2 provided on the clamp 311 can be used to abut against the contact 81. Part of the first conductive arm 1 and part of the second conductive arm 2 provided on the driving end 315 can be used to be electrically connected to the wire.

[0109] For example, the connector in this embodiment is applied to a connection component. The connection component includes the connector in this embodiment and a wire. The wire includes a plurality of first wires and a plurality of second wires. The ends of the plurality of first wires are electrically connected to the ends of the plurality of first conductive arms 1 disposed at the driving end 315, respectively. The ends of the plurality of second conductive arms 2 are electrically connected to the ends of the plurality of second conductive arms 2 disposed at the driving end 315, respectively. At the same time, the ends of the plurality of first conductive arms and the plurality of second conductive arms are provided with independently disposed extension sections. When the first conductive arm 1 and the second conductive arm 2 are opened or retracted, the distance between the ends of the first conductive arm 1 and the second conductive arm 2 disposed at the driving end 315 will change, and the extension section can be used to avoid pulling the first conductive wire and the second conductive wire.

[0110] The connection component can be used to connect electronic devices. For example, the first terminal row and the second terminal row of the connector are configured as the Type-C interface type. As a result, the service life of the connection component is increased, 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.

[0111] In some embodiments, Figure 3-Figure 5 As shown, the mounting frame 31 is an insulating injection molded part. The mounting frame 31 can be made of rubber. When the first conductive arm 1 and the second conductive arm 2 are arranged on the mounting frame 31, the current on the first conductive arm 1 and the second conductive arm 2 can be prevented from being conducted to the outside of the connector through the mounting frame 31.

[0112] The driving clamp 3 further includes two pairs of inlays 33 spaced apart from each other along the axial direction of the rotating shaft 32, and the inlays 33 include ears 331 and a fixing body 332. The ears 331 have connecting holes 333. The ears 331 extend toward opposite sides of the two mounting brackets 31, and the connecting holes 333 are rotatably sleeved on the rotating shaft 32. That is, the rotating shaft 32 passes through four connecting holes 333 at the same time.

[0113] During the injection molding process of the mounting frame 31, the fixing body 332 can be disposed in the base of the mounting frame 31. Thus, after the mounting frame 31 is solidified, the insert 33 and the mounting frame 31 are fixed together.

[0114] Specifically, the inlay 33 in this embodiment is made of metal, such as an iron-based alloy. Therefore, this embodiment uses the high hardness of the inlay 33 to ensure the movement accuracy of the first conductive arm 1 and the second conductive arm 2 when the mounting frame 31 rotates along the rotating shaft 32 through the inlay 33. In particular, when the elasticity of the compression spring is large and the number is large, it can be avoided that the connection position of the mounting frame 31 and the rotating shaft 32 is deformed by only connecting the mounting frame 31 to the rotating shaft 32.

[0115] In some embodiments, Figure 2-Figure 4 As shown, the connector further comprises a shell 5. The shell 5 comprises a cover 51. The cover 51 has an accommodating channel 511 and two fixing holes 512 arranged on the side wall of the accommodating channel 511.

[0116] When the driving clamp 3 is disposed in the accommodating channel 511 , both ends of the rotating shaft 32 are connected to the two fixing holes 512 respectively.

[0117] In this embodiment, the accommodating channel 511 can be used to accommodate the connector, so that the driving clip 3 can move in the cover body 51. At the same time, the driving clip 3 and the cover body 51 can be fixed together by using the fixing hole 512 provided on the cover body 51.

[0118] In some embodiments, Figure 4-Figure 6As shown, the side wall of the accommodating channel 511 has a plurality of limiting grooves 513. The mounting frame 31 includes two limiting bosses 317, which are protrudingly arranged on both sides of the mounting frame 31 and extend into the limiting grooves 513.

[0119] When the two clamps 311 are opened at a predetermined angle, the side wall of the limiting boss 317 abuts against the side wall of the limiting groove 513 .

[0120] When the two clamps 311 of this embodiment are opened or closed, the limiting boss 317 will move in the limiting groove 513. When the side wall of the limiting boss 317 abuts against the side wall of the limiting groove 513, the distance between the two clamps 311 can be limited to avoid the distance between the two being too large. For example, the first conductive arm 1 and the second conductive arm 2 are arranged in the plug-in channel 521, and the driving assembly 6 is used to drive the two clamps 311 to open. In this embodiment, the limiting boss 317 cooperates with the limiting groove 513 to avoid the first conductive arm 1 and the second conductive arm 2 abutting against the inner wall of the plug-in channel 521, causing excessive bending.

[0121] In some embodiments, Figure 4 and Figure 6 As shown, the accommodating channel 511 has a first connecting end 5111 and a second connecting end 5112 .

[0122] The shell 5 further includes a receiving body 52 , which is disposed at the first connection end 5111 and has a plug-in channel 521 . The plug-in channel 521 is used to accommodate the plug-in component 8 , so that the plug-in component 8 is fixedly connected to the receiving body 52 .

[0123] The side wall of the accommodating channel 511 further has a plurality of avoidance grooves 514 , which correspond one-to-one to the plurality of limiting grooves 513 . One end of the avoidance groove 514 extends to the second connecting end 5112 , and the other end extends to the limiting groove 513 .

[0124] The avoidance groove 514 in this embodiment is used to avoid the limiting boss 317 when the first terminal block and the second terminal block are installed in the shell 5 .

[0125] Specifically, the first terminal row and the second terminal row are respectively inserted into the accommodating channel 511, and the first conductive arm 1 and the second conductive arm 2 are extended into the plug-in channel 521. In this process, the limiting boss 317 can slide into the limiting groove 513 along the avoidance groove 514. Then, the rotating shaft 32 is passed through the two fixing holes 512 and the connecting hole 333 set on the ear 331 to complete the assembly of the connector.

[0126] In some embodiments, Figure 3 and Figure 6As shown, the connector further comprises a shell 5. The shell 5 comprises a receiving body 52. ​​The receiving body 52 has a plug-in channel 521, and the plug-in channel 521 is provided with an escape window 5211, which is formed by the inner wall of the plug-in channel 521 being recessed toward the outside.

[0127] Further reference Figure 3-Figure 4 As shown, the first conductive arm 1 and the second conductive arm 2 both include a bent section 11 . The bent section 11 is close to the ends of the first conductive arm 1 and the second conductive arm 2 , and the bent section 11 is bent away from the side wall of the plug channel 521 to form an electrical contact area 12 .

[0128] Further reference Figure 6-Figure 7 and Fig. 9 As shown in state I in the figure, the two clamps 311 are in a state of being away from each other, that is, when the two clamps 311 are clamped, the ends of the first conductive arm 1 and the second conductive arm 2 extend into the avoidance window 5211.

[0129] Specifically, Figure 1 and Figure 6 As shown, the insertion channel 521 has a socket 5212. The receiving body 52 includes two flat side walls and two curved side walls. The two curved side walls are connected between the two curved side walls and connected end to end, so that the socket 5212 is runway-shaped. The avoidance window 5211 in this embodiment is arranged on the flat side wall, and the plurality of first conductive arms 1 and the plurality of second conductive arms 2 are respectively arranged corresponding to the two flat side walls.

[0130] When the two clamps 311 are opened, the first conductive arm 1 and the second conductive arm 2 will move toward the two flat side walls. In this form, the avoidance window 5211 provided on the flat side wall can be used to accommodate the ends of the first conductive arm 1 and the second conductive arm 2 (such as Figure 8 As shown), the first conductive arm 1 and the second conductive arm 2 can be opened at a larger angle to avoid interference between the first conductive arm 1 and the second conductive arm 2 and the flat side wall.

[0131] Alternatively, if Figure 3 As shown, the avoidance window 5211 passes through the plug-in channel 521. The connector also includes an insulating patch 9. The insulating patch 9 can be made of foam. Therefore, by sealing the insulating patch 9 on the outside of the avoidance window 5211, leakage of electricity at the ends of the first conductive arm 1 and the second conductive arm 2 can be avoided during the connection between the connector and the plug-in connector 8. At the same time, when the first conductive arm 1 and the second conductive arm 2 are opened, the insulating patch 9 is uncovered, and the end of the first conductive arm 1 or the second conductive arm 2 located in the avoidance window 5211 is abutted by a test tool to detect the on-off condition.

[0132] In some embodiments, Figure 6-Figure 7As shown, the shell 5 further includes a plurality of stop bars 53 . The stop bars 53 are convexly arranged on the inner wall of the plug-in channel 521 , and the plurality of stop bars 53 extend along the axial direction of the plug-in channel 521 and pass through the avoidance window 5211 , and the length direction of the avoidance window 5211 is consistent with the arrangement direction of the plurality of stop bars 53 .

[0133] Further reference Fig. 9 As shown, in the process of the two clamps 311 approaching or moving away from each other, the first conductive arm 1 and the second conductive arm 2 swing between the stop bars 53. Thus, the first conductive arm 1 and the second conductive arm 2 are prevented from bending in the arrangement direction of the plurality of stop bars 53 under the drive of the two clamps 311, and the accuracy of the first conductive arm 1 and the second conductive arm 2 contacting the contact point 81 is further improved.

[0134] In some embodiments, Figure 7-Figure 8 As shown, the plug-in channel 521 has a socket 5212 . The plug connector 8 can be inserted into the plug-in channel 521 from the socket 5212 .

[0135] Further reference Figure 6 and Fig. 9 As shown, the shell 5 also has a limiting tongue 54. The limiting tongue 54 is arranged in the insertion channel 521 and extends in a direction away from the socket 5212.

[0136] When the two positioning portions 312 abut against each other, the end of the first conductive arm 1 and the end of the second conductive arm 2 are placed on the limiting tongue 54, and the electrical contact areas 12 of the first conductive arm 1 and the second conductive arm 2 are spaced apart (such as Fig. 9 (as shown in state II).

[0137] In this form, the connector is in an unconnected state, that is, the plug-in connector 8 is not inserted into the plug-in channel 521, and the elastic member 4 holds the two clamps 311 together. In this embodiment, the first conductive arm 1 and the second conductive arm 2 are limited by the latch 54 to prevent the bent sections 11 of the first conductive arm 1 and the second conductive arm 2 from being attached together under the drive of the elastic member 4, resulting in a short circuit between the first conductive arm 1 and the second conductive arm 2.

[0138] Fig.10 1 is a schematic diagram of the structure of the test fixture of this embodiment. The receiving body 52 in the figure is located at the bottom. Fig.11 1 is a schematic diagram of the structure of the driving assembly 6 and the bearing assembly 7 of this embodiment. The area shown in the enlarged view in the figure is used to set the above-mentioned connector. Fig.12 It is an exploded schematic diagram of the driving assembly 6 and the bearing assembly 7 of this embodiment.

[0139] In some embodiments, Figure 10-12As shown, the test fixture in this embodiment includes a drive assembly 6 and a connector. The drive assembly 6 includes a first drive head 61 and a second drive head 62, which are arranged opposite to each other and can be operated to move closer to or farther from each other.

[0140] Further reference Figure 1-Figure 6 As shown, the connector in this embodiment includes an elastic member 4, a driving clamp 3, and a plurality of first conductive arms 1 and a plurality of second conductive arms 2. The driving clamp 3 includes two mounting frames 31 and a rotating shaft 32, and the two mounting frames 31 are rotatably connected through the rotating shaft 32. The mounting frame 31 includes a clamp 311 and a positioning portion 312, and the positioning portion 312 is located at opposite sides of the two clamps 311. The elastic member 4 is arranged on the driving clamp 3, and the plurality of first conductive arms 1 and the plurality of second conductive arms 2 are respectively arranged on the two mounting frames 31 and extended from the two clamps 311.

[0141] The first driving head 61 and the second driving head 62 respectively drive the two mounting frames 31 to rotate, and the two clamps 311 drive the first conductive arm 1 and the second conductive arm 2 to move away from each other, so that the connector 8 can be inserted between the first conductive arm 1 and the second conductive arm 2 .

[0142] When the first driving head 61 and the second driving head 62 are away from the connector, the elastic member 4 can also drive the two mounting frames 31 to reset, and at the same time, the two clamps 311 drive the first conductive arm 1 and the second conductive arm 2 to approach each other until the two positioning parts 312 abut against each other, so that the first conductive arm 1 and the second conductive arm 2 can contact with the contact 81 on the plug-in component 8 at the same time, ensuring the contact stability.

[0143] In summary, in the test fixture of this embodiment, the elastic member 4 of the connector is arranged on the driving clamp 3, and the two mounting frames 31 of the driving clamp 3 are configured to rotate relative to each other through the rotating shaft 32. The first conductive arm 1 and the second conductive arm 2 are respectively arranged on the two mounting frames 31, and the ends of the first conductive arm 1 and the second conductive arm 2 are extended from the clamp 311. Thus, when the two clamps 311 are driven away from each other, the first conductive arm 1 and the second conductive arm 2 are opened at a predetermined angle, so that the connector 8 can be inserted between the first conductive arm 1 and the second conductive arm 2. In this process, friction between the first conductive arm 1 and the second conductive arm 2 and the connector 8 can be avoided. The service life of the first conductive arm 1 and the second conductive arm 2 is improved, and foreign matter can be prevented from adhering to the surface of the first conductive arm 1 and the second conductive arm 2 during multiple frictions.

[0144] On the other hand, when the two clamps 311 are not driven, the elastic member 4 drives the two clamps 311 to approach each other, and the first conductive arm 1 and the second conductive arm 2 can move toward the contact 81 of the connector to electrically connect the connector to the plug-in component 8. In this process, the two positioning parts 312 are used for limiting, which can ensure that the first conductive arm 1 and the second conductive arm 2 are stably connected to the contact 81, and can also avoid excessive pressure between the first conductive arm 1 and the second conductive arm 2 and the contact 81, so as to further protect the contact 81 and the first conductive arm 1 and the second conductive arm 2.

[0145] In some embodiments, Figure 3-Figure 5 As shown, the elastic member 4 is a compression spring and abuts between two mounting brackets 31. The mounting bracket 31 has a driving surface 313, and the rotating shaft 32 is located between the driving surface 313 and the positioning portion 312. The driving surfaces 313 of the two mounting brackets 31 are away from each other.

[0146] The connector in this embodiment includes a shell 5. The shell 5 has a plug-in channel 521, and the plug-in channel 521 has a socket 5212.

[0147] The test fixture in this embodiment also includes a bearing assembly 7. The bearing assembly 7 has a receiving opening 71 and two stoppers 72. The two stoppers 72 are arranged at one end of the receiving opening 71. When the connector is arranged in the receiving opening 71, the shell 5 abuts against the two stoppers 72, and the socket 5212 extends to the side of the receiving opening 71 away from the stoppers 72. Therefore, when the plug-in component 8 is inserted into the plug-in channel 521, the stoppers 72 can play a limiting role to prevent the connector from being ejected from the receiving opening 71.

[0148] In this form, the driving assembly 6 is configured to drive the first driving head 61 and the second driving head 62 to abut against the two driving surfaces 313 respectively, so that the two clamps 311 are separated from each other. At the same time, the elastic member 4 generates a restoring elastic force. The restoring elastic force can drive the two clamps 311 to close again after the first driving head 61 and the second driving head 62 are separated from the connector, so that the first conductive arm 1 and the second conductive arm 2 can contact the contact 81 of the connector 8.

[0149] Specifically, the driving assembly 6 further includes two slide rail assemblies 63. The two slide rail assemblies 63 are arranged on the support block. The sliders of the two slide rail assemblies 63 drive the first driving head 61 and the second driving head 62 to move along the same straight line, thereby driving the driving clamp 3 to move.

[0150] In some embodiments, Figure 1-Figure 6As shown, the shell 5 in this embodiment includes a cover body 51. The cover body 51 has a receiving channel 511 and two fixing holes 512 arranged on the side wall of the receiving channel 511. The driving clip 3 is arranged in the receiving channel 511 and the two ends of the rotating shaft 32 are respectively connected to the two fixing holes 512. The side wall of the receiving channel 511 has a plurality of limiting grooves 513, and the limiting grooves 513 penetrate the side wall of the receiving channel 511. The mounting frame 31 includes two limiting bosses 317, and the two limiting bosses 317 are convexly arranged on both sides of the mounting frame 31 and extend into the limiting grooves 513.

[0151] Further reference Fig.11 As shown, the bearing assembly 7 further includes a plurality of clamping blocks 73, and the plurality of clamping blocks 73 extend into the plurality of limiting grooves 513 one by one. The two clamping heads 311 are opened at a predetermined angle, and the side wall of the limiting boss 317 abuts against the limiting groove 513.

[0152] The limiting groove 513 that penetrates the receiving body 52 in this embodiment can limit the opening range of the clamp 311 and also play a positioning role, so that the connector will not shake easily in the receiving opening 71.

[0153] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
