Detailed Description

The present invention will be described in further detail with reference to examples and drawings, but the present invention is not limited thereto.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "provided," "connected," and the like are to be construed broadly, such as "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-3, the specific implementation of the present invention is as follows: a power supply adapting line comprises an AC plug 1, a circuit board 2 and a DC lead 4, wherein the AC plug 1 is provided with an AC pin 11 and an insulating protective body 3, one end of the AC pin 11 penetrates through the insulating protective body 3 to be welded and fixed with the front end of the circuit board 2, the front end of the insulating protective body 3 is connected with the front end of the circuit board 2 in an adhesion mode, the rear end of the circuit board 2 is electrically connected with the DC lead 4, and the circuit board 2 and the DC lead 4 are arranged inside the insulating protective body 3.
