Description

Audio signal terminal

technical field

The utility model relates to a terminal, in particular to an audio signal terminal.

Background technique

Please refer to FIG. 5, an audio signal terminal 100' has a positioning piece 10', and one end of the positioning piece 10' extends forward to form an elastic arm 11'. The audio signal terminal 100' is applied to an audio signal connector (Fig. not shown). The external audio plug is inserted into the audio signal connector and contacts with the elastic arm 11', so that the audio plug is electrically connected with the audio signal terminal 100' to transmit the audio signal.

However, when the elastic arm 11' of the above-mentioned existing audio signal terminal 100' is in contact with the audio plug, it is only a single point of contact, and the contact is often unstable due to dust or debris on the contact point. This makes the audio plug easy to loosen and cause poor contact, thereby affecting the quality of audio signal transmission.

Utility model content

The purpose of the utility model is to provide an audio signal terminal for the defects of the prior art, and the audio signal terminal can ensure the stable transmission of the audio signal.

To achieve the above purpose, the audio signal terminal of the present invention includes a holding portion, a welding foot and two elastic arms. The holding portion includes a bottom wall and two side walls bent and extended from opposite side edges of the bottom wall. The welding foot is connected with the holding part. One side of the two sidewalls is obliquely extended to form an elastic arm, and the ends of the two elastic arms are respectively obliquely extended to form a pressing part, and two protrusions protrude inward on the two pressing parts respectively.

As mentioned above, the audio signal terminal of the present invention can form at least two contact points when the audio signal terminal is connected with an audio plug by virtue of the two pressing parts and the protrusions respectively provided on the two pressing parts, so that The electrical connection between the audio plug and the audio signal terminal is more stable, thereby ensuring stable transmission of the audio signal.

Detailed ways

In order to describe the technical content, structural features, achieved purpose and effect of the present utility model in detail, the following will be described in detail in combination with specific embodiments and accompanying drawings.

Please refer to FIG. 1, the audio signal terminal 100 of the present invention has a holding portion 10, the holding portion 10 has a bottom wall 11 and two side walls 20 bent and extended from the opposite side edges of the bottom wall 11, the two sides One side of the wall 20 extends obliquely inwards and then outwards to form an elastic arm 21, and the ends of the two elastic arms 21 extend inwards and then outwards to form a roughly arc-shaped pressing force. part 22, and two protrusions 221 protrude side by side on the inner side of the two pressing parts 22 respectively. One of the side walls 20 has a rectangular buckle 23 that is punched outward in the roughly middle part, and the top of the side wall 20 is bent and extended outward to form a welding foot 24, and an oval opening 241 is provided on the welding foot 24. A locking block 25 protrudes upward from the top of the side wall 20 .

Please refer to FIG. 2 and FIG. 3 , the audio signal terminal 100 of the present invention is applied in an audio signal connector 200 . The audio signal connector 200 has an insulating body 30, an insertion hole 31 is provided in the insulation body 30, and a first groove 32 that runs through the front surface of the insulation body 30 is provided at the left bottom of the insertion hole 31. The first groove The bottom of 32 is provided with an opening 321 that runs through the lower surface of the insulating body 30; the bottom right side of the insertion hole 31 is provided with a second groove 33 that runs through the lower surface of the insulating body 30, and the right side of the second groove 33 is provided with a through hole 32. The locking groove 34 on the right surface of the insulating body 30 communicates with the second groove 33 . A groove 35 extending to the front and right surfaces of the insulating body 30 is defined on the right side of the front end of the lower surface of the insulating body 30 . The groove 35 is located below the locking groove 34 and communicates with the bottom of the second groove 33 .

When assembled, the audio signal terminal 100 of the present invention is inserted into the insulating body 30 from the rear direction of the insulating body 30, the bottom wall 11 is placed on the top of the insertion hole 31, and the two side walls 20 are respectively inserted in the first groove 32 and the second groove. In the slot 33, the block 25 is engaged in the opening 321, the buckle 23 is engaged in the slot 34, and the welding foot 24 protrudes out of the groove 35 and is welded and fixed on the circuit board (not shown), so that The audio signal terminal 100 is fixedly inserted into the insulating body 30 .

Please refer to Fig. 1 and Fig. 4, when an external audio plug 300 is inserted from the socket hole 31, the pressing parts 22 of the two elastic arms 21 are pressed against the top of the audio plug 300, which can strengthen the connection between the audio signal terminal 100 and the audio plug 300. The fixing effect enhances the conductivity; in this embodiment, two protrusions 221 protrude from the inner sides of the two pressing parts 22 respectively, so that the audio signal terminal 100 and the audio plug 300 form four contact points, so that the audio plug 300 The electrical connection formed with the audio signal terminal 100 is more stable and reliable to transmit audio signals.

In summary, the audio signal terminal 100 of the present invention relies on the two opposite elastic arms 21 and the convex shells 221 arranged side by side on the two elastic arms 21, so that when the audio plug 300 and the audio signal terminal 100 are docked, the contact position There may be at least two contact points, so that the electrical connection between the audio plug 300 and the audio signal terminal 100 is more stable, ensuring stable transmission of audio signals.
