Description

Technical Field

[0001] The present invention relates to a universal wire clamping device, an electrical plug connector, and a female socket of an electrical plug connector. Background Art

[0002] The electrical plug connector is used to establish an electrical connection between a first cable and a second cable, or is also used to establish an electrical connection between a first cable and an electrical appliance. Among them, the wire clamping device is a device that presses the first cable and the second cable onto a cutting knife to establish a connection. Therefore, the wire clamping device has a great impact on the signal transmission quality. There are many cutting knives on the market. If a wire clamping device is manufactured for each cutting knife, it will inevitably increase costs and waste resources. Therefore, it is necessary to invent a wire clamping device that can be universally matched with various cutting knives. Summary of the Invention

[0003] To overcome the above disadvantages, one of the objectives of the present invention is to provide a universal wire clamping device. The second objective of the present invention is an electrical plug connector with the wire clamping device.

[0006] Preferably, the first cutting knife includes a cutting type cutting knife and / or a piercing type cutting knife.

[0007] Preferably, the cutting type cutting knife includes a first cutting knife body, a card slot extending to the middle is arranged on the upper part of the first cutting knife body, the inner side wall of the card slot is pressed into a knife edge shape for cutting the wire to contact the inner conductor of the wire, and a connecting part for connecting a PCB board is arranged on the lower part of the first cutting knife body. The knife edge-shaped inner side wall of the card slot can cut the wire when the wire is pressed into the card slot and connect with the inner conductor of the wire to play a role in data transmission.

[0008] Preferably, the piercing knife comprises a second knife body, and the upper portion of the second knife body is provided with first, second and third thorn-like vertices.

[0009] Preferably, the central axes of the first, second and third thorn-shaped vertices are inclined in different directions. When the cable is pressed in, the thorn-shaped vertices will pierce the cable and connect with the inner conductor of the cable to play a role in data transmission. The piercing-type card knife pierces the cable from three directions, which has the advantages of higher data transmission efficiency and better stability than the cutting-type card knife.

The paddle is slidably arranged on the upper cover of the electrical plug connector, and the other end of the paddle extends to the outside of the upper cover of the electrical plug connector to form a paddle portion for a finger to paddle. By adding a paddle that can be paddled externally and designing the paddle to be linked to the spring, the finger does not need to be inserted into the plug-in portion of the electrical plug connector. The electrical plug connector can be removed from the interface of the server by simply pulling the paddle externally. It is easy to operate, effectively solves the problem of insufficient space in densely wired servers affecting user experience, and effectively avoids the service life problem caused by insufficient downward pressure of the spring.
