Description

network socket connector

technical field

The utility model relates to the technology in the field of network connectors, in particular to a network socket connector with enhanced plugging force.

Background technique

With the rapid development of information technology, the application of electronic and information products is becoming more and more extensive, and the progress of computer systems and related peripheral industries is even more rapid. The widespread popularity of computers, coupled with the rapid development of network technology, enables people to quickly obtain the required information through the network, and can also obtain a variety of information services. The development of computer networks provides human beings with a more convenient and comfortable living environment. . In order to pursue higher network speed and better Internet access quality, the requirements for the signal transmission quality between the network socket connector and the network connector are also higher. Nowadays, people generally use the specifications of the RJ-45 network connector and the corresponding network socket. The connectors are coupled, and the network connector and the network socket connector need to be in stable contact to ensure stable signal transmission between the two.

The traditional network socket connector is provided with metal shrapnel on the inner surface of both sides of the shielding shell, so that when the network plug is inserted into the socket of the network socket connector, the network plug is pressed against and compressed by the shrapnel, so that the network plug is stably accommodated in the socket. Therefore, stable signal transmission is achieved between the network plug and the network socket connector. This kind of metal shrapnel set on the shielding shell exposes the following disadvantages:

1. The metal shrapnel and the shielding shell are integrally formed. It is necessary to use a metal material with good elasticity to ensure the plug resistance of the shrapnel, so that the entire shielding shell needs to be made of better metal materials, resulting in the production of the shielding shell. The cost is too high.

2. The structure design of the metal shrapnel is relatively complicated, and it needs to be stamped or bent many times, which makes it difficult to guarantee the quality of the shrapnel. The mold making is also more complicated, which increases the manufacturing cost and makes it difficult to reduce the overall cost.

3. Under repeated use, the elasticity of the metal shrapnel will gradually fail, so that the metal shrapnel is difficult to reset after being pressed by the network plug. Because the plugging force provided by the shrapnel is insufficient, the network plug cannot be effectively contacted with the network interface, and the received signal unstable.

The terminal group 30 is arranged in the insulating body 20, and includes an insulating part 31 and a conductive terminal 32 mounted on the insulating part. The conductive terminal 32 is arranged parallel to the insertion direction and is used for electrical contact with the docking network plug. One terminal has a butt portion 321 bent upwards and backwards, and the butt portion 321 can be matched with a contact end of a corresponding network plug. The end of each terminal extends downward to form a solder pin 322 that can be joined to the circuit board.

The signal indicating device 40 is used to display the power signal and the network signal respectively, and includes a light emitting diode 41 and a pair of pins 42 extending backward from the light emitting diode and bent downward.

The insulating body 20 is installed in the shielding shell 10 and is made of plastic. The insulating body 20 includes an upper surface 21 , a lower surface 22 , a front surface 23 , a rear end surface 24 , and left and right side surfaces 25 , 26 , and a socket 27 capable of accommodating an IE network plug is formed inside.

On top of that, please refer to FIG. 3 , the left and right inner walls 251 of the above-mentioned socket 27 extend an elastic piece 29 integrally at a certain angle along the insertion direction. The elastic piece 29 can be in any shape. In this embodiment, the elastic piece and the side surface It is roughly U-shaped, the front side forms a contact surface 294 for abutting against the network plug, and the back side forms a deformation space 291 with the inner wall 251 . The elastic piece 29 includes a connecting portion 292 and an elastic portion 293. The connecting portion 293 extends vertically from the above-mentioned inner wall surface 251 and is located in the middle of the left and right inner wall surfaces of the insertion port 27, so as to provide a balanced resistance when it is in contact with the network plug. tension, while the elastic part 293 is bent from the top end of the connecting part 292 and extends toward the insertion direction.

The production process of 251 integral molding is easy to demould, which is convenient for the molding of shrapnel.

In practical applications, when the network plug is inserted into the socket 27 of the network socket connector, the elastic part 293 of the elastic piece 29 will generate a pressure pointing to the direction of the two sides 25 and 26, forcing the elastic part 293 to deform, and the elastic part will be squeezed toward the deformation Space 291, so that the network plug is clamped tighter, thus, the network plug is fixed in the socket 27. When the network plug is pulled out, the elastic portion 293 of the elastic piece recovers due to loss of pressure.

To sum up, the key point of the design of this utility model is to extend a shrapnel from the left and right inner walls of the socket along the insertion direction. On the one hand, because the shrapnel is made of plastic and has a considerable thickness, the insertion force is greatly enhanced. On the other hand, it is injection molded with the insulating shell at one time, and it is not necessary to consider the bending angle and elastic factors of the shrapnel during production, which simplifies the complexity of manufacturing and improves the competitiveness of the product market.
