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. 4 , a conventional audio signal terminal 20 has a holding portion 21 , a welding portion 22 formed by extending the holding portion 21 , an elastic arm portion 23 formed by bending and extending, and an arc at the end of the elastic arm portion 23 . The contact portion 24 is formed by bending and extending, and the holding portion 21 is used for holding on an insulator (not shown in the figure). Please refer to Fig. 5, when the audio socket (not shown) equipped with the audio signal terminal 20 and other connecting terminals (not shown) is connected and matched with the audio plug 30, the audio signal terminal 20 elastically pushes against the audio signal only from one side. The plug 30 makes the audio plug 30 easy to bend, and the bending of the audio plug 30 easily further leads to poor contact between the audio plug 30 and other connection terminals, thereby affecting the quality of the audio socket.

Please refer to FIG. 6 , another existing audio signal terminal 40 includes a connecting portion 44, two holding portions 41 extending vertically from both ends of the connecting portion 44 and having a width greater than the width of the connecting portion 44, and two holding portions 41 and the two elastic arm parts 43 formed by bending to one side of the holding part 41 respectively on the same side, the two contact parts 45 formed by bending and extending the ends of the two elastic arm parts 43 respectively, and one end connected by the two holding parts 41 and the connecting part 44 The two welded portions 42 extend respectively. Please refer to Fig. 7, when the audio socket (not shown) equipped with the audio signal terminal 40 and other connecting terminals (not shown) is matched with the audio plug 30, the audio signal terminal 40 can be connected by two elastic arm parts 43 It elastically abuts against the audio plug 30 from both sides. However, this audio signal terminal 40 not only has a complex structure and is difficult to manufacture, but also has a small abutting force between the two elastic arm parts 43 and the matching audio plug 30, and it is easy to push to one side. The resultant force of the audio plug 30 causes the audio plug 30 to bend; correspondingly, it also causes poor contact between the audio plug 30 and other connecting terminals.

Utility model content

The main purpose of this utility model is to provide an audio signal terminal which has a simple structure, is easy to manufacture, and can be tightly and reliably abutted with a matching audio plug and can prevent the matching audio plug from bending.

In order to achieve the above purpose, the frequency signal terminal of the present invention has a connecting part, the two ends of the connecting part are vertically bent and extended to the same side to form a sheet-shaped first holding part and a sheet-shaped second holding part, the first holding part One side edge is bent and extended to form an elastic arm part located between the first holding part and the second holding part, and the end of the elastic arm part is bent and extended to form a contact part protruding toward the second holding part, and the second holding part A contact protrusion protrudes from the first holding part on the side of the first holding part and is opposite to the contact part, and a welding part is connected to the first holding part.

As mentioned above, the audio signal terminal of the present invention can elastically contact with the opposite audio plug by means of the contact part and the contact convex part can rigidly contact the opposite audio plug, so that the matching audio plug can be inserted into the audio signal terminal. When the audio socket is used, reliable positioning can be achieved, and it is not easy to be bent, thereby ensuring that each terminal of the audio socket using the audio signal terminal is in close and reliable contact with the matched audio plug, thereby increasing the pull-out force of the audio plug.

Detailed ways

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

Please refer to Fig. 1 and Fig. 2, the audio signal terminal 1 of the present utility model is used for being installed on an audio socket (not shown in the figure), and this audio signal terminal 1 comprises a rectangular plate-shaped connection part 15, and the two ends of the connection part 15 A sheet-shaped first holding portion 11 and a sheet-shaped second holding portion 16 are formed by bending and extending perpendicularly to the same side. The widths of the first holding portion 11 and the second holding portion 16 are greater than that of the connecting portion 15 . A notch 111 is defined on the first holding portion 11 , and one edge of the notch 111 extends downward to form a propping piece 18 , which can be used to abut against an insulator (not shown) of an audio socket. One side edge of the first holding portion 11 is bent and extended to form an elastic arm portion 13 located between the first holding portion 11 and the second holding portion 16 , and the end of the elastic arm portion 13 is bent toward one side of the second holding portion 16 After extending, it is bent and extended to one side of the first holding part 11 to form a contact part 14, and the end edge of the first holding part 11 connected with the connecting part 15 extends outward to form a welding part 12, and the inner side of the second holding part 16 The surface protrudes inwardly with a contact protrusion 17 opposite to the contact portion 14 and in rigid contact. The first holding portion 11 and a second holding portion 16 are used to hold on the insulator, and the welding portion 12 can be used for welding on the circuit board. (not shown) on.

Please refer to FIG. 3 , when the audio signal terminal 1 of the present utility model is in contact with the audio plug 2 , the contact portion 14 is elastic and in elastic contact with the audio plug 2 , while the contact convex portion 17 is in contact with the audio plug 2 . rigid contact.

The audio signal terminal 1 of the present utility model can be elastically contacted by the contact part 14 with the docked audio plug, and can be rigidly contacted by the contact convex part 17 with the docked audio plug, so that the matched audio plug 2 can be used when the audio signal terminal 1 is inserted. When the audio socket is used, reliable positioning can be achieved, and bending is not easy to occur, thereby ensuring that each terminal of the audio socket using the audio signal terminal 1 is in close and reliable contact with the matched audio plug 2, thereby increasing the pull-out time of the audio plug 2. contribute.
