Electrical connector

The present invention provides an electrical connector, in particular, a rotating cover with a pressing member pivoted on a terminal group positioned inside the seat body, and a reinforcing member with rigidity and hardness is bonded on the surface of the rotating cover by gluing. The shape of the reinforcing member and the rotating cover can be made equivalent, thereby improving the overall service life.

According to the rapid development of electronic technology and the Internet today, various electronic related products have been introduced, and gradually become light, thin, short, small, easy to carry, and the operation and transmission speed are speeding up. The volume of electronic products is shrinking, and the electronic components with different functions inside the electronic products need to be more miniaturized and precise, and the overall structural strength needs to be strengthened to meet the development trend of current electronic products.

Furthermore, in order to enable the electronic components in the electronic related products to perform their functions, the electrical connector interface is generally used as a bridge for electrical signal transmission and communication between the two, and the signal transmission is electrically connected. Designers of the device usually design for the dual development of increasing the amount of signal transmission and miniaturization. Therefore, the number of terminals is small, and the volume is light, thin, short, and small. Flexible Printed Circuit (FPC) type Connectors have emerged as the times require, and are increasingly being used in computers and their surrounding electronic devices.

However, as shown in the seventh and eighth figures, it can be clearly seen from the figure that the inside of the insulative housing A is formed with the insertion space A0, and the terminal group A1 is set in the insertion space A0, and A support member A2 is disposed at two sides of the insulative housing A, and a metal plate C is embedded in the cover B by means of a cover injection, and a cover B is extended on both sides of the metal plate C and pivoted to the support. When the flexible circuit board D is inserted into the insertion space A0 of the insulative housing A from the opening A01, the pivoting plate C can be pulled by the cover B to form the pivot C1 of the metal plate C as the axis. Rotating, and pressing by the cover B to push against the surface of the flexible circuit board D, and pressing the cover B to the position, the flexible circuit board D can be clamped on the cover B and the elastic piece A11 of the terminal group A1. A good electrical connection state is formed between the contact portions A111 at one side.

However, the cover B is formed by covering the metal plate C in the cover B by means of the coating, so that the metal plate C must be relatively narrow in size with the cover B, so that the metal plate C can be surely covered by the cover. In B, the shape and thickness of the metal plate C are limited by the structure of the cover B itself, and after the metal plate C is reduced to a certain shape, the user may apply force to press or cover the cover B. It is easy to cause deformation or structural damage due to insufficient strength of the metal plate C, and even the original function failure of the cover B and the metal plate C, thereby affecting the service life of the electrical connector, and there is still much room for improvement in the overall structural design. , those who are still in the industry to redesign to effectively solve.

Therefore, the new creators, in view of the problems and shortcomings of the conventional electrical connectors, collected the relevant materials through various evaluations and considerations, and used the trial and modification of the years of R&D experience in the industry to design such electricity. The new connector was born.

The main purpose of the present invention is to form a docking space between the base and the side wall of the base body, and a pressing member is pivotally connected to the terminal group of the base, and the rotating cover of the pressing member is pivotally connected to a rotating shaft on the terminal group, and a reinforcing member is coupled to the surface of the resisting portion extending outward from the rotating shaft, and when the flexible circuit board is inserted into the docking space of the seat body, the reinforcing member of the pressing member can be pulled, and The resisting portion of the rotating cover is rotatably pushed against the surface of the flexible circuit board to be electrically connected to the terminal group by pressing down. The surface of the rotating cover of the pressing member directly combines the reinforcing member with rigidity and hardness. The shape of the reinforcing member and the rotating cover can be made equivalent, so as to avoid the shape and thickness of the reinforcing member which must be reduced with the predetermined size of the rotating cover by the covering and shooting manner, so that the pressing member can maintain good rigidity and hardness. It is not easy to cause deformation or structural damage, which improves its overall service life.

The secondary purpose of this creation is that the rotating cover of the pressing member is made of plastic material, and has good self-lubrication, wear resistance and heat resistance, and the reinforcing member is integrally formed of metal or ceramic material. When formed, the reinforcing member can be combined with the engaging surface of the rotating cover by the gluing method to form a flat shape. When the user pulls the reinforcing member of the pressing member, the rotating cover is connected with the rotating shaft as the axis. When rotating, the reinforcing member can be used with good rigidity and hardness, and deformation or structural damage is not easy, and the overall structure is more stable.
