Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.

As shown in fig. 1 and 2, in embodiment 1, the invention provides a unit connector, which includes a connector sheath 1, where the connector sheath 1 is provided with an accommodating groove 2 for accommodating a terminal, an outer side wall of the connector sheath 1 is provided with a clamping mechanism and a hanging structure, and two adjacent connector sheaths 1 can be connected through the clamping mechanism and the hanging structure. In this embodiment, the positions of the fastening mechanism and the hanging structure can be set according to specific use requirements.

Specifically, the clamping mechanism comprises guide rails 3 and guide grooves 5, in this embodiment, the number of the guide rails 3 and the number of the guide grooves 5 are two, the two groups of guide rails 3 are respectively vertically arranged on the front side wall and the right side wall of the connector sheath 1, and the two groups of guide grooves 5 are respectively vertically arranged on the rear side wall and the left side wall of the connector sheath 1. Every group guide rail 3 all includes two tracks 31 that mutual symmetry set up, and every group guide slot 5 all includes two channels 51 that mutual symmetry set up, and the distance between two channels 51 of every group guide slot 5 is greater than the distance between two tracks 31 of every group guide rail 3, and accessible track 31 realizes being connected with the joint of channel 51 between two adjacent connector sheaths 1. The hanging structure comprises hanging noses 4 and hanging points 6, the hanging noses 4 are arranged between two tracks 31 of each guide rail 3, the hanging points 6 are arranged between two channels 51 of each guide groove 5, and hanging can be realized by the hanging noses 4 and the hanging points 6 between two adjacent connector sheaths 1, so that the connection between the two adjacent connector sheaths 1 is more reliable.
