Detailed Description

Referring to fig. 1 to 3, a specific structure of a preferred embodiment of the present invention is shown, which includes a plastic seat 10 and a power terminal 20.

The upper and lower surfaces of the plastic seat 10 are penetrated by a mounting cavity 101, and the bottom surface of the plastic seat 10 is provided with two positioning plates 11 protruding downwards at intervals, and the two positioning plates 11 fix the plastic seat 10.

The power supply terminals 20 are disposed in the mounting cavities 101, and in the present embodiment, there are three power supply terminals 20, correspondingly, there are three mounting cavities 101, and three power supply terminals 20 are disposed in the corresponding mounting cavities 101. The product is a heavy current product, and can reach more than 40A.

The power supply terminal 20 comprises a base 21 and a plug part 22 which are integrally formed and connected from bottom to top, wherein an external thread 211 is arranged on the outer wall of the base 21, an internal thread 102 is correspondingly arranged at the lower end of the mounting cavity 101, the external thread 211 is in threaded connection with the internal thread 102, and the two are connected more firmly by adopting a threaded connection mode.
