Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the present invention will be further described with reference to the following embodiments and accompanying drawings.

Referring to fig. 1-4, in order to illustrate one embodiment of the present invention, the power converter mounting box with single end lead includes a box body 1 and a lead-out end cap 2.

In this embodiment, the box body 1 is a hollow structure for storing the power converter, and both ends thereof are provided with openings 11; the outgoing line end cover 2 is of a combined structure, the outgoing line end cover 2 is composed of an outgoing line end shell 21 and a grounding bottom plate 22, two outgoing line holes 211 are formed beside the outgoing line end shell 21, one outgoing line hole is an alternating current input lead hole, and the other outgoing line hole is a direct current output lead hole; the grounding bottom plate 22 is used as a ground wire for connecting the internal power converter with the outside, the grounding bottom plate 22 is slidably connected to the bottom of the outlet end shell 21 and is internally buckled in one of the openings 11 of the box body 1 so as to seal the opening 11, and the part of the grounding bottom plate 22, which is internally connected in the box body 1, is provided with an internal grounding hole 224 for realizing electrical connection with the power converter.

Specifically, the outlet end shell 21 has a hollow cavity structure, two inner sides of the bottom of the outlet end shell 21 are respectively provided with a sliding groove 212, and the grounding bottom plate 22 is in sliding fit with the outlet end shell 21 along the sliding groove 212; the grounding bottom plate 22 is a metal conductor, the grounding bottom plate 22 comprises a sliding portion 221, a switching portion 222 and an external portion 223, the sliding portion 221, the switching portion 222 and the external portion 223 are sequentially connected and formed into a step-shaped structure, namely, the sliding portion 221 is located on the upper edge of one side of the switching portion 222, the external portion 223 is located on the lower edge of the other side of the switching portion 222, an internal grounding hole 224 is formed in the surface side of the sliding portion 221, the sliding portion 221 is embedded between the two sliding grooves 212 in the matching process of the outgoing end shell 21 and the grounding bottom plate 22, the external portion 223 protrudes out of the outgoing end shell 21, a hook hole 225 for connecting a metal hook is formed in the external portion 223, and a top connection groove 213 matched with the switching portion 222 is formed in the bottom of the outer side of the.
