Description

Audio socket connector 【0001】

The present invention relates to an audio jack connector, and more particularly to an audio jack connector that is structurally easy to assemble.

【0002】

According to the first figure, a conventional audio socket connector includes an insulative housing, and a plurality of signal terminals, elastic terminals and a plurality of switch terminals mounted in the insulating body. The insulating body has a plug hole and is insulated. The bottom surface of the main body forms a plurality of terminal slots connecting the plug holes, and the signal terminals and the switch terminals are mounted upwardly from the bottom surface of the insulating body to the terminal slots, wherein the plurality of signal terminals include a right channel signal terminal, a left channel signal terminal, a ground terminal, and a microphone sound. The circuit terminal, wherein the plurality of switch terminals comprise a first switch terminal and a second switch terminal, wherein the first switch terminal and the second switch terminal form an electrical circuit through the elastic abutment, thereby providing the installed electronic device to detect whether the audio socket connector has The audio plug is plugged in.

[0003]

In order to maintain the electrical circuit when the first switch terminal and the second switch terminal of the audio jack connector are not inserted into the audio plug, the first switch terminal and the second switch terminal must maintain a positive force against each other, thus assembling the audio In the socket connector, the first switch terminal and the second switch terminal are assembled first, and the latter must be inserted into the terminal slot through the step of compressing the terminal, so that the first switch terminal and the second switch terminal can be installed. After the insulating body, it is elastically abutted.

[0004]

However, the above assembly process causes great inconvenience whether it is assembled manually or assembled using an automated machine. The steps of compressing the terminals will complicate the assembly steps, which not only increases the number of working hours, but also is disadvantageous for large quantities. Production directly increases production costs.

[0005]

Therefore, in order to make the assembly process easier and faster, there is an urgent need for an audio jack connector structure that can preferably combine the first switch terminal and the second switch terminal.

[0006]

The purpose of the present invention is to provide an audio jack connector structure capable of better combining the first switch terminal and the second switch terminal in view of the defects and deficiencies of the prior art, which can simplify the assembly steps and reduce the production cost.

【0007】

In order to achieve the above object, the present invention provides an audio socket connector for mounting on an electronic device for docking an audio plug, comprising an insulative housing and a plurality of terminals, including a pair of connecting surfaces, a left side wall and a right side wall, and facing the insulating body. A plurality of terminal slots are defined in the left side wall and the right side wall, and the plurality of terminal slots are connected to the plurality of terminal slots, and the plurality of terminals are included in the plurality of terminal slots, including a plurality of signal terminals, a flexible terminal, a first switch terminal, and a first The two switch terminals, the first switch terminal and the second switch terminal respectively comprise a contact portion. The upper surface of the contact portion of the first switch terminal is provided with an upward and outwardly extending tab, and the inner surface of the tab is formed to extend outward. Slant into the edge.

[0008]

The contact portion of the first switch terminal and the contact portion of the second switch terminal elastically abut each other, and the tab is located at the elastic abutment.

【0009】

The oblique edge is a curved surface or a sloped surface.

[0010]

The plurality of terminal slots include a first terminal slot on the left side wall and an elastic terminal slot and a switch terminal slot located behind the first terminal slot, the switch terminal slot is located outside the elastic terminal slot, and the second terminal is sequentially opened on the right side wall a slot, a third terminal slot, and a fourth terminal slot, the plurality of signal terminals including a first terminal, a second terminal, a third terminal, and a fourth terminal, the first terminal, the second terminal, the third terminal, the fourth terminal, and the elastic terminal The first switch terminal and the second switch terminal are mounted in the switch terminal slot, respectively, in the first terminal slot, the second terminal slot, the third terminal slot, the fourth terminal slot, and the elastic terminal slot.

[0011]

The front end of the contact portion of the first switch terminal is provided with an insulating block, and the first terminal includes a contact portion, and the insulating block is adjacent to the outer side of the end edge of the contact portion of the first terminal, and the audio plug is mortgaged when the plug is inserted into the plug hole. The contact portion of the terminal is elastically deformed outwardly by the end edge of the contact portion to be elastically deformed outwardly against the insulating block. At this time, the insulating block drives the contact portion of the first switch terminal to be elastically deformed outward, so that the contact of the first switch terminal is made. The portion is separated from the contact portion of the second switch terminal to realize the open circuit of the switch.

[0012]

In summary, a contact piece is disposed on the contact portion of the first switch terminal. During the installation process of the first switch terminal, the oblique edge of the tab can elastically push the contact portion of the second switch terminal to the inside. The deformation acts to enable the contact portion of the first switch terminal to be smoothly mounted into the switch terminal slot in a vertically depressed manner. Therefore, the original audio socket connector can be easily assembled or assembled automatically, which simplifies assembly steps and reduces production cost.
