The power connection end cover 70 is installed at one end of the housing 1, the wiring end cover 80 is installed at the other end of the housing 1, and the power connection components 2 are installed inside the housing 1. Specifically, in this embodiment, four sets of power connection components 2 are provided.

[0058] In this embodiment, the outer shell 1 is a plastic shell. For example... Figure 1 , Figure 6 and Figure 7 As shown, the outer shell 1 serves as the main support structure of the connector. One end of the shell is provided with a plug sleeve 10, and the other end is provided with an external plug cavity 20. The plug sleeve 10 extends to the outlet of the external plug cavity 20.

[0059] The plug-in sleeve 10 is provided with a plug-in fixing seat 30. The plug-in fixing seat 30 includes a first plug portion 31 and a second plug portion 32 connecting the first plug portion 31. The plug-in fixing seat 30 has four mounting cavities 33, which pass through the first plug portion 31 and the second plug portion 32. The four sets of power connection components 2 are installed in the four mounting cavities 33 one by one. The power connection components 2 are fixed in the plug-in fixing seat 30 to ensure their stable position and prevent displacement during use from affecting signal transmission.
