Description

Socket structure of electronic connector

【Technical field】

The utility model relates to a socket structure of an electronic connector, in particular to a light, thin and small USB (Universal Serial Bus) electrical connector.

【Background technique】

An application of an electronic connector usually has a socket and a plug. The socket is set in an electronic device, and the plug is inserted into the socket to complete the supply of signals or power.

A known USB receptacle connector includes a body, a tongue plate and a plurality of terminals, the body has a housing cavity, the tongue plate is made of plastic, and is located in the housing cavity, and the plurality of terminals are stamped and formed. Assembly or Insert molding) on the tongue plate to form a contact portion and a welding portion, and the welding portion is welded and fixed with the PCB board.

This conventional USB connector has the following disadvantages:

1. The tongue is made of plastic. During the continuous use and plugging process, cracks and damage often occur due to insufficient strength of the plastic product.

2. The welding part of the terminal is connected to the printed circuit board by soldering, and the soldering cracks are often caused by repeated plugging and unplugging.

In view of this, the creator of the present invention devoted himself to the research and development of connectors based on the spirit of excellence, innovation and breakthrough, and created the socket structure of the utility model electronic connector, which can effectively solve the problem of strength.

【Content of invention】

The purpose of this utility model is to provide a socket structure of an electronic connector, which has the effect of improving the structural strength to achieve the purpose of being more durable.

In order to achieve the above-mentioned effect and purpose, the utility model is characterized in that it includes a main body, which is provided with a fixing part and a receiving cavity, and the receiving cavity is formed with an insertion port and an output port; a metal tongue plate, which is arranged on the main body and a flexible circuit board, on which a plurality of electronic circuits are formed, the flexible circuit board is provided with a fixed end and an output end, the fixed end is fixed on the metal tongue plate, the The output end is passed through the output opening outside the housing cavity of the body.

In this way, setting the flexible circuit board on the metal tongue can improve its structural strength, and the body is fixed by the fixing part, and then electrically connected to the printed circuit board through the soldering of the flexible circuit board, so that the plugging force will not Transfer to the flexible circuit board, there will be no tin cracking problem.

The above and other purposes, advantages and features of the present invention are described in detail below with reference to the drawings for a better understanding of the preferred examples.

【Detailed ways】

Please refer to FIG. 1 , FIG. 2 , FIG. 3 and FIG. 4 , the socket structure of the electronic connector of the present invention includes a main body 10 , a metal tongue plate 12 , a flexible circuit board 14 and a rear cover 16 . The main body 10 has a receiving cavity 18 , and the receiving cavity 18 is formed with an insertion port 20 and an output port 22 . Metal tongue plate 12, it is arranged on the body 10, and is located in the receiving chamber 18; A flexible circuit board 14, is formed with a plurality of electronic circuits 24 on it, flexible circuit board 14 is provided with a fixed end 26 and an output The end 28 and the fixed end 26 are fixed on the metal tongue plate 12, and are fixed to each other by the back cover 16. The back cover 16 is also fixed on the output port 22 of the main body 10, and the output end 28 is passed through the output port 22 on the main body. The outside of the receiving cavity 18 of 10 is used for soldering with a printed circuit board (not shown).

And the body 10 has a fixing portion 30, which is used to be fixed on a base (not shown in the figure). In this way, when the docking connector (not shown in the figure) is inserted into the receiving cavity 18 of the body 10, since the body 10 is fixed It will not affect the soldering of the flexible circuit board 14 and the printed circuit board, and the combination is relatively stable. Furthermore, the metal tongue plate 12 can increase its strength without breaking, and the flexible circuit board 14 is fixed on the metal tongue plate 12, which is more convenient for assembly.

The specific embodiments proposed in the detailed description of the preferred embodiments are only for easy understanding of the technical content of the utility model, and do not limit the creation to the embodiments in a narrow sense. All cases according to the spirit of the creation and the scope of the following patent applications The implementation of various changes made all belong to the scope of the present utility model.
