Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The terms "comprises" and "comprising," and any variations thereof, in the described embodiments of the invention, and in the claims and drawings, are intended to cover a non-exclusive inclusion, such as a list of steps or elements.

The technical solution of the present invention will be described in further detail with reference to the accompanying drawings and embodiments.

As shown in fig. 1-9, an embodiment of the present invention provides a device for a fool-proof connector, which includes a connection terminal 1 and a mating connection sheath 2.

Foolproof bubble points 102 are arranged on two side walls of the functional area of the wiring terminal 1, and an elastically deformable barb 101 is arranged at the bottom end of the wiring terminal 1;

the butt-joint connecting sheath 2 comprises a plurality of connecting through grooves 201 arranged in a row, foolproof ribs 202 are arranged on two side walls in the connecting through grooves 201, and fastening blocks 203 are arranged at the bottoms of the connecting through grooves 201.

In the assembling process, the wiring terminal 1 is inserted into the opposite connection sheath in the forward direction, the terminal is smoothly inserted, the barb 101 is buckled on the buckling block 203, and as shown in fig. 6, when the terminal is inserted in the reverse direction, the insertion is not in place due to the interference between the fool-proof bubble point 102 position and the fool-proof rib 202 position of the wiring terminal 1, so that the risk that the wiring terminal is not buckled and falls off due to the fact that the wiring terminal 1 is reversely inserted into the opposite connection sheath 2 is avoided.
