Description

Electrical connector

The invention provides an electrical connector, in particular, a movable body with a positioning mechanism coupled to the movable seat inside the seat body, and the rotating body can be rotated and opened when the movable seat is withdrawn, so as to facilitate the rotation of the external electrical connector. The insertion interface at the inner side of the moving body is inserted into the movable seat, and the elastic buckle on the plug is fastened in the limiting portion on the rotating body, and the stability of the overall structure is ensured.

According to the rapid development of electronic technology today, electronic devices such as notebook computers and tablet computers have become commonplace in all corners of the society, and because of the rapid development of the Internet, users are required to obtain instant information, transfer files or mail. You can connect to the Internet to work through electronic devices, and use the Internet to search for various information, instant messaging or online games.

Furthermore, as the development trend of notebook computers and tablet PCs tends to be thin and light, the electronic components on the internal circuit board of the electronic device must be reduced and more precise, and the overall structural strength needs to be followed. It is reinforced, and the general electronic device uses a connector to connect to the circuit board, and the connector can be connected to the network plug and connected to the plurality of signal terminals, thereby transmitting the signal through the circuit board to In the control circuit, the electronic device is connected to the network for work.

With the smaller and smaller size of electronic devices, various types of connectors have been developed, and the plug types can be generally divided into RJ-11 plugs for use in telephones, fax machines, etc., and electronic devices can be connected to the network. RJ-45 plugs used in multi-function machines, but because RJ series connectors are standard and have a certain size, today's notebook computers, tablet computers and other electronic devices have lower thickness design requirements than RJ series connectors. In order to improve the overall thickness of the electronic device, it is impossible to make the above-mentioned problem, and a manufacturer has designed a cap-type connector which is attached to the base for pivoting a cover plate, and A slot is formed between the base and the cover for the plurality of terminals to be inserted. When the network plug is to be inserted into the slot of the base, the cover can be turned over and pivoted upward. At an oblique angle, the network plug is inserted obliquely into the slot, but the cover of the clamshell connector often has too much force to turn up when the cover is opened, causing the pivot to jump off The shaft hole on the cover, and The cover plate is separated from the base, and the overall structure is relatively unstable. In addition, when the cover is closed, the internal space of the slot can be made smaller to reduce the overall height of the connector, but the cover plate is inclined at an angle when opened. When the network plug is inserted obliquely into the slot, it will occupy a certain height, so that the overall use of the clamshell connector still occupies more space, and those who are still engaged in this industry are redesigned to effectively solve the problem.

Therefore, in view of the above-mentioned problems and shortcomings in the use of the above-mentioned clamshell connectors, the inventors have collected and collected relevant data through various evaluations and considerations, and have continuously tried and modified the years of research and development experience in this industry. A patent for the invention of the electrical connector was born.

The main purpose of the present invention is to provide a rotating body with a positioning mechanism on the movable seat inside the seat body, and a plug-in interface formed at the inner side of the rotating body, which can be rotated when the movable seat is withdrawn from the movable seat. The body is rotated outward to be in an open state, so that the plug of the external electrical connector is laterally inserted into the docking space of the movable seat from the plug interface, and is electrically connected with the plurality of mating terminals, and the elastic buckle on the plug The positioning is held in the limiting portion of the rotating body to ensure the stability of the overall structure.

A secondary object of the present invention is that the positioning mechanism includes a rotating body and a cover that can be positioned outside the bottom of the movable seat, and pivots the shaft hole at the front end of the two sides of the rotating body to the outer casing or the movable body. The protruding column on the shaft portion at the front of the two sides of the seat can elastically retract the torsion spring on the protruding post with the two end pins elastically supporting the movable seat or the shaft portion and the rotating body, and then has an elastic reset function. The outer casing cover is positioned at the bottom of the movable seat, so that the rotating body is pivotally connected to the shaft portion of the outer casing or the movable seat to open or close, and the outer casing is prevented from rotating by the outer periphery of the shaft hole of the rotating body. When the moving body rotates, the situation outside the shaft portion occurs, and the stability and smoothness of the rotating body are ensured.

Another object of the present invention is that when the user wants to fold the movable seat into the sliding space of the seat body, the rotating body of the positioning mechanism needs to be rotated to the inner side to be closed, and then by the second time. The pressing method allows the sliding space of the movable seat to be laterally reciprocating and sliding, and the auxiliary movable seat smoothly completes the folding or withdrawing, and the overall height is reduced and thinner, so as to meet the design requirements of light and thin products.
