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 cause the grounding signal to be unstable, which will affect 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.

In order to achieve the above object, the present invention adopts the following technical solution: an audio connector, The insulative housing includes a receiving space, a plug-in interface, and an end surface opposite to the plug-in interface; the conductive terminal is received in the insulating body, the conductive terminal includes a signal terminal and a grounding terminal, and the grounding terminal The invention includes a holding portion, a contact portion extending into the receiving space, a welding portion extending from the insulating body, and a connecting portion connecting the holding portion and the welding portion between the holding portion and the welding portion, and the end portion of the welding portion connected to the connecting portion A tongue is extended, and the tongue and the holding portion are held together with the insulating body.

Compared with the prior art, the grounding terminal of the audio connector of the present invention has a tongue plate that is held by the insulating body, which prevents the occurrence of deformation of the outer terminal of the grounding terminal, and has a good electrostatic conducting effect.

Referring to the first to fourth figures, the audio connector 100 of the present invention is connected to a cable (not shown) or a contact spring (not shown) for receiving a docking connector (not shown), which includes The insulative housing 1 and the plurality of conductive terminals 2 housed in the insulative housing 1.

Referring to the first and third figures, the insulative housing 1 includes an annular head portion 11 and a rectangular body portion 12. The insulative housing 1 defines a receiving space 13 penetrating the head 11 and the body portion 12 . The insulative housing 1 defines an insertion interface 14 at the head 11 and an end surface 15 behind the body portion 12 opposite the insertion interface.

Referring to the second to fourth figures, the conductive terminal 2 includes a protrusion from the left side. The first signal terminal 21 and the second signal terminal 22 of the accommodating space 13 and the third signal terminal 23 and the fourth signal terminal 24 projecting into the accommodating space 13 from the right side and the ground terminal 25 protruding from the upper side into the accommodating space 13 are formed. Each of the signal terminals 21, 22, 23, 24 includes a holding portion 26 that is held by the insulative housing 1, a contact portion 27 that extends into the receiving space 13, and a welded portion 28 that extends out of the insulative housing 1. The grounding terminal 25 includes a holding portion 256 that is fixed to the insulative housing 1 , a contact portion 257 that extends into the receiving space 14 , and a soldering portion 258 that is exposed to the insulative housing 1 , and includes a connecting portion 259 that is exposed to the rear end surface 15 of the insulative housing 1 . . 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. One end of the soldering portion 258 connected to the connecting portion 259 is extended with a tongue plate 2591 held by the insulating body 1. The tongue plate 2591 and the holding portion 256 interfere with the insulative housing 1 in the upper and lower planes. The tongue plate 2591 is formed by tearing from the connecting portion 259. The soldering portions 28 of the signal terminals 21, 22, 23, and 24 and the soldering portions 258 of the grounding terminals 25 are uniformly extended from the rear end surface 15 of the insulating body 1 and arranged in a row. The soldering portion 258 of the ground terminal 25 is located between the soldering portions 28 of the signal terminals 21, 22, 23, 24. All the welded portions 28, 281 are located on the same plane, are evenly distributed, and have a considerable width and length, so that they can be used for different processes such as surface mount (SMT), cable soldering or contact spring crimping, which is advantageous for the expansion of the process.

The grounding terminal 25 of the audio connector 100 of the present invention is held by the tongue plate 2591 and the insulative housing 1 to prevent the occurrence of external deformation of the grounding terminal 25, and the static electricity guiding effect is good.
