Detailed Description

The present application is described in further detail below with reference to figures 1-5.

The embodiment of the application discloses a DB plug. Referring to fig. 1, the DB plug includes a mounting socket 1 and a wire insertion hole 11 opened on the mounting socket 1.

Referring to fig. 1 and 2, a terminal post 2 for conduction is provided in the wire insertion hole 11, and the terminal post 2 includes a connection portion 21 extending deeply into the mounting base 1 and a wire connection portion 22 facing the outside of the mounting base 1. Wherein, wiring hole 223 is opened on wiring portion 22, and the electric connection of DB plug can be realized to the contact pin that waits to connect inserts in wiring hole 223.

Referring to fig. 2 and 3, there is a space between the wire connecting portion 22 and the wall of the wire insertion hole 11, and the wire connecting portion 22 has a plurality of deformation gaps 221 on the wall of the peripheral wall of the wire connection hole, one side of the deformation gap 221 penetrates the wire connecting portion 22 to the outside of the wire insertion hole 11, and the wire connecting portion 22 is partitioned by the deformation gaps 221 to form a plurality of insertion hole pieces 222 with outward expanding petals. Specifically, in the present embodiment, the deformation gap 221 is opened six times, and the wire connecting portion 22 forms six insertion hole pieces 222 through the six deformation gaps 221.
