Description

Audio connector

The invention provides an audio connector, in particular an audio connector with good static conduction effect.

In the consumer electronics arena, many electronic devices, such as mobile phones, MP3 players and other portable audio devices, require an external audio headset or earpiece to hear the sound of the media. As such, an audio connector must be installed on these audio devices for plugging in headphones or earpieces. The audio connector generally includes an insulative housing and a plurality of conductive terminals. The insulative housing is provided with a receiving cavity for receiving the plug and a plurality of receiving slots communicating with the receiving cavity. The conductive terminal is received in the receiving slot. The conductive terminal comprises a grounding terminal, and the grounding terminal is generally placed close to the front end of the plugging interface, so that the static electricity is guided away in time before the other conductive terminal contacts the mating connector. Also, to achieve the waterproof effect, the audio connector minimizes the opening in other directions than the tail. The grounding terminal is inserted from the tail and extends to the front end of the plug connector. The grounding terminal has a long structure and is prone to deformation of the outer sheet. The above situation will affect the soldering of the ground terminal to the printed circuit board, resulting in unstable grounding signal, which in turn affects the static conduction effect.

In view of this, it is necessary to provide a new audio connector to overcome the above drawbacks.

It is an object of the present invention to provide an audio connector with good static conduction effect.

The connecting portion 259 is located between the holding portion 256 and the welded portion 258 and connects the holding portion 256 and the welded portion 258. The holding portion 256 and the welded portion 258 extend in the insertion direction, and the connecting portion 259 extends in a vertical direction perpendicular to the insertion direction. The contact portion 257 extends close to the plug interface to preferentially contact the mating connector to conduct the static electricity in time. A wing portion 2591 extends from both side edges of the connecting portion 259, and the wing portion 2591 is held by the insulating body 1. The wing portion 2591 interferes with the insulative housing 1 in the vertical direction, and the retaining portion 256 interferes with the insulative housing 1 in a horizontal direction that is perpendicular to the plugging direction and the vertical direction at the same time.

Referring to the second and third figures, the connection portion 259 of the ground terminal 25 is exposed on the rear end surface of the insulative housing 1 and the soldering portions 28 of all the conductive terminals 2 are exposed on the mounting surface of the insulative housing 1. Therefore, the waterproof film 5 Attached to the rear end surface of the insulative housing 1 and the mounting surface. The inside and outside of the audio connector 100 are separated by the waterproof film 5, and liquid substances such as water are prevented from entering the audio connector 100 from the inside of the casing of the electronic device.

Referring to the first figure, the waterproof ring 4 is sleeved on the neck portion 13 of the insulative housing 1. The waterproof ring 4 is pressed by the casing of the electronic device to seal the assembly gap between the casing and the audio connector 100, thereby avoiding the gap. Liquid substances such as water enter the casing from the outside.
