[0052] Furthermore, the clamping portion 141 is disposed in the accommodating cavity 12 and does not extend to the external connection portion 11 at most; ensuring that the clamping portion 141 is disposed in the accommodating cavity 12, that is, ensuring that the clamping portion 141 is in the installation groove 130, is to prevent the clamping portion 141 from moving at will, facilitate installation, and improve the stability of the electrical connection.

[0053] For further information, please refer to Figure 2 , the conductive member 14 and the insulating plate 13 are both of a hierarchical structure; the layered conductive member 14 and the insulating plate 13 are arranged. In actual production, the number of layers of the conductive member 14 can be increased to meet the signal flow between more wires. Each layer of the conductive member 14 is arranged in the installation groove 130 of the insulating plate 13, so that the insulating plate 13 can protect the conductor in the installation groove 130. At the same time, when there are multiple layers of conductive members 14, the insulating plate 13 can also isolate adjacent conductive members 14 to prevent mutual interference between different signals.

[0054] For further information, please refer to Figure 2 and Figure 4 The insulating plate 13 has one more layer than the conductive member 14, so that the mounting groove 130 and the adjacent insulating plate 13 form a mounting cavity 133, and the conductive member 14 is fixed in the mounting cavity 133; the insulating plate 13 has one more layer than the conductive member 14, ensuring that both sides of the conductive member 14 can be fully protected and fixed, thereby improving the connection stability of the equipment.
