Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a test fixture for preventing scratches on crystal heads. Background Technology

[0002] Before leaving the factory, RJ45 connectors undergo testing, primarily to assess their withstand voltage and other performance metrics. In existing technology, the testing fixture typically has a grounding component on one side of the connector. This grounding component prevents leakage current from the connector during testing, thus avoiding a safety hazard to workers. However, this rigid contact between the grounding component and the connector makes the connector susceptible to scratches. Summary of the Invention

[0003] This invention addresses the problems of existing technology by providing a test fixture to prevent scratches on crystal heads, thus preventing scratches when crystal heads are inserted into the socket.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a test fixture for preventing scratches on crystal heads, including a main body and multiple sockets disposed on the main body. The main body is also provided with multiple grounding springs, which are disposed one-to-one with the multiple sockets. The grounding springs are located on one side of the sockets and are used to abut against the crystal head inserted into the sockets.

[0006] Furthermore, a grounding base is provided on one side of the socket, a grounding spring is installed on the grounding base, a wire is connected to the end of the grounding spring, and a grounding plate is provided on the main body, with the wire fixing the grounding plate.

[0007] Furthermore, the main body is provided with multiple guide holes, and the wires are assembled one-to-one with the guide holes. After passing through the guide holes, the wires are soldered to the grounding plate.

[0008] Furthermore, the grounding spring includes a needle body, a needle tip, and an elastic element. The needle body is mounted on the grounding base and connected to the wire. The needle body has a mounting hole. The needle tip is movably disposed in the mounting hole and protrudes outward through the mounting hole. The elastic element is disposed in the mounting hole and is used to force the needle tip to move outward toward the needle body. A limiting structure is provided between the needle body and the needle tip to prevent the needle tip from detaching from the needle body.

[0009] Furthermore, the main body is provided with a cavity, and an electrical module is provided inside the cavity. Multiple ports are connected to the electrical module.

Detailed Implementation

[0017] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0018] This utility model provides a test fixture for preventing scratches on crystal heads, including a main body 1 and multiple sockets 2 disposed on the main body 1. The main body 1 is also provided with multiple grounding springs 3, which are disposed one-to-one with the multiple sockets 2. The grounding springs 3 are located on one side of the sockets 2 and are used to abut against the crystal head inserted into the sockets 2.

[0019] When in use, the staff inserts the crystal head into the socket 2. The crystal head will force the corresponding grounding spring 3 to retract, thereby ensuring that the grounding spring 3 is in contact with the crystal head, allowing the elastic force between the two to absorb and release energy, avoiding the phenomenon of rigid collision, and achieving the effect of protecting the crystal head from scratches.

[0020] In this embodiment, a grounding base 11 is provided on one side of the socket 2, and a grounding spring pin 3 is installed on the grounding base 11. A wire 12 is connected to the end of the grounding spring pin 3, and a grounding plate 13 is provided on the main body 1. The wire 12 fixes the grounding plate 13. That is, the grounding base 11 is perpendicular to the side of the main body 1 where the socket 2 is provided, while the grounding spring pin 3 is arranged parallel to the side of the main body 1 where the socket 2 is provided, so that the grounding spring pin 3 is located on the side of the crystal head inserted into the socket 2, ensuring reliable contact between the two.

[0021] Specifically, the main body 1 is provided with multiple guide holes 10, and the wires 12 are assembled one-to-one with the guide holes 10. After passing through the guide holes 10, the wires 12 are soldered to the grounding plate 13. The guide holes 10 serve to allow the wires 12 to enter the interior of the main body 1, realizing the wire gathering operation of the wires 12.

[0022] Specifically, the grounding spring needle 3 includes a needle body 31, a needle tip 32, and an elastic element 33. The needle body 31 is installed on the grounding base and connected to the wire 12. The needle body 31 has a mounting hole. The needle tip 32 is movably disposed in the mounting hole and protrudes outward through the mounting hole. The elastic element 33 is disposed in the mounting hole and is used to force the needle tip 32 to move outward toward the needle body 31. A limiting structure 34 is provided between the needle body 31 and the needle tip 32. The limiting structure 34 is used to prevent the needle tip 32 from detaching from the needle body 31.

[0023] In actual use, the limiting structure 34 mainly consists of a first limiting part 35 disposed on the needle body 31 and a second limiting part 36 disposed on the needle tip 32. Please refer to [reference needed] for details. Figure 3 The elastic element 33 is preferably a spring, and the needle body 31 and the needle tip 32 are kept connected by the elastic element 33, thereby ensuring that the current generated by leakage of the crystal head can be delivered to the grounding plate 13 for release after passing through the grounding spring pin 3 and the wire 12.

[0024] In this embodiment, the main body 1 is provided with a cavity, and an electrical module 14 is provided in the cavity. Multiple sockets 2 are connected to the electrical module 14. The top of the main body 1 is provided with an opening, and a top cover 15 for covering the opening is detachably provided on the top of the main body 1.

[0025] The electronic module uses a conventional circuit structure, which will not be described in detail here. This invention connects to external testing equipment via the electrical module 14, allowing the RJ45 connector inserted into socket 2 to exchange current with the external testing equipment, thus achieving the testing effect. A current collector can also be installed at the grounding plate 13 to collect whether current flows through it, thereby determining whether the RJ45 connector is leaking.

[0026] Specifically, the top cover 15 is equipped with a power switch 16, which is located at the output end of the electrical module 14. The electrical module 14 is connected to external testing equipment via the power switch 16. The power switch 16 is primarily made of a metal sheet and a metal groove, with the metal sheet positioned on the top cover and the metal groove installed between the electrical module 14 and the socket 2. When the top cover 15 is reliably fixed to the main body 1, the metal sheet is inserted into the metal groove, allowing the electrical module 14 to conduct electricity with the testing equipment. When the top cover 15 is detached from the main body 1, the metal sheet detaches from the metal groove, thus ceasing conductivity. This ensures that the present invention conducts electricity only when the top cover 15 is closed to the main body 1, guaranteeing safety.

[0027] In this embodiment, the outer surface of the grounding spring pin 3 is covered with an insulating layer.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
