Abstract
Description
Technical Field
[0001] This utility model relates to the field of signal pin connection structure technology, specifically to signal module mounting structure and electrical connector. Background Technology
[0002] A connector is an electronic component used to connect power sources and electronic devices. It typically consists of a plug and a socket, facilitating the connection and disconnection of power. Power connectors are widely used in various electronic devices. Existing power connectors mainly achieve contact between internally distributed pins and the pins inside the connector to achieve the effect of electrical connection and transmission.
[0003] Existing PIN pins are all bent. Although the connection with the internal pins of the connector is achieved through the protruding bent PIN pin pins, the fatigue resistance will be reduced due to the characteristics of highly conductive materials. In the end, the contact will be unstable due to insufficient normal force. At the same time, the bending degree of such pins is insufficient during repeated insertion and removal over a long period of time, which will eventually affect the stability of the connection with the connector. Therefore, this signal module mounting structure and electrical connector were designed to avoid the risk of PIN retraction during insertion. Utility Model Content
[0004] The purpose of this utility model is to provide a signal module mounting structure and an electrical connector. By inserting the signal pin into the signal module and using a pressure plate to fix the rear of the signal module and the rear of the signal pin, the risk of pin ejection is eliminated during insertion.
[0005] This utility model provides the following technical solution: a signal module mounting structure, including a plug housing, a signal module inserted into the plug housing, a first mounting cavity formed at the bottom of the plug housing, a pressure plate embedded in the first mounting cavity, the signal module fixed between the pressure plate and the plug housing, a signal pin inserted into the signal module, the signal pin passing through the pressure plate, and one end of the signal pin extending to the outside of the pressure plate.

[0007] Furthermore, the end of the signal needle is needle-shaped, and the signal needle includes a positioning part, a connecting part, and a plug-in part. The junction of the positioning part and the connecting part is stepped, and the junction of the connecting part and the plug-in part is also stepped. One end of the connecting part is located on the end face of the pressure plate. The pressure plate limits the signal needle and fixes the connecting part of the signal needle to one end of the pressure plate.
[0008] Furthermore, the other end of the connecting part is located on the top wall of the signal module, the top wall of the signal module is stepped, the plug-in part is inserted and located above the signal module, and the signal module limits the signal pin to prevent the signal pin from slipping out.
[0009] In an embodiment of the female plug, the top of the plug housing is a flat plate, and multiple sockets corresponding to signal pins are provided on the top of the plug housing. The ends of the signal pins are located inside the signal module.
[0010] Furthermore, the end of the signal pin is two clamping plates, and a second retaining ring is formed on the top wall of the signal module. The second retaining ring is located at the upper end of the clamping plates and limits the clamping plates to prevent the signal pin from slipping out during insertion.
[0011] Furthermore, an arc-shaped protrusion is formed on the inner wall end of the clamping plate to enhance the clamping force on the male signal pin.
[0012] This utility model also provides a technical solution: an electrical connector, including the aforementioned male plug and the aforementioned female plug, wherein a male signal pin is inserted and fixed inside the male plug, and a female signal pin is inserted and fixed inside the female plug. The male signal pin and the female signal pin are inserted into each other and are arranged in a cross shape.

[0013] Furthermore, the female plug is provided with a insertion groove, and the male plug is formed with a insertion rib. The insertion groove and the insertion rib interlock with each other. The male plug and the female plug are positioned by interlocking the insertion groove and the insertion rib to prevent reverse insertion.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are:
