Description

audio socket connector

technical field

The utility model relates to a connector, in particular to an audio socket connector.

Background technique

Referring to Fig. 5, a conventional audio socket connector includes an insulating body 1', an abutment terminal 2' received on the insulating body 1', and several connecting terminals 3'. The insulating housing 1' includes a main body 11' and a butt joint 12' extending from one end of the main body 11'. The insulating body 1' defines an insertion hole (not shown in the figure) from the docking part 12' into the main body part 11'. An abutment terminal groove 15' and a plurality of connection terminal grooves 16' communicated with the insertion hole (not shown in the figure) are opened on the insulating body 1'; the abutment terminal groove 15' accommodates the abutment terminal 2', A connecting terminal 3' is respectively accommodated in the connecting terminal groove 16'. The contact terminal 2' has a holding part 21', a welding part 24' extending from the holding part 21', an elastic part 22' formed by bending and extending one side edge of the holding part 21', and an elastic part. The contact portion 23' is formed by bending and extending the end of 22' in an arc shape.

However, when an audio plug 30' is inserted into the insertion hole of the above-mentioned audio socket connector, since the contact portion 23' of the abutting terminal 2' elastically pushes against the audio plug 30' from one side, it is easy to make the audio plug 30' move toward the audio plug 30'. One side is inclined, which not only makes it difficult for the contact portion 23 ′ to make reliable contact with the audio plug 30 ′, but also affects the electrical connection between the other connecting terminals 3 ′ and the audio plug 30 ′.
