Description

universal connector

The utility model relates to a universal connector, especially a USB universal serial port connector. The male connector is provided with an elastic hook body, and the female connector forms a connector structure in which the locking part is relatively locked and combined. In order to achieve a reliable connection and prevent falling off.

The use of connectors enables computers, telecommunications and other electrical equipment to have a good signal transmission connection method, and also allows us to quickly and flexibly combine the internal and external expansion structures of electrical appliances, or to carry out communication connections at both ends of the remote place, so The effect of connector connection has extraordinary significance for the transmission of electrical signals in electrical appliances.

Among various connectors, there is a USB Universal Serial Bus Connector (Universal Serial Bus Connector), as shown in Figure 1, which is composed of a male connector 100 and a female connector 200. It is fixed on the circuit board 300, and there is a socket hole 201 on it to plug in the plug end of the male connector 100, and the other end of the male connector 100 protrudes from the cable 101, so that the electrical signal can pass through the cable. 101 is transmitted or transmitted from the female connector 200 to the circuit board 300 corresponding to the function to produce an effect. This structure has the following deficiencies:

1. Due to the connection between the male connector 100 and the female connector 200, only the joint seat 2A is provided in the socket 201, and the elastic card 2B is provided at the outer end, and there is no fastening device. If a person accidentally touches the cable 101 At this time, it is easy to pull the male connector 100 out of the insertion hole 201 to separate it from the female connector 200, resulting in cutting off the electrical transmission signal between the male/female connector 100/200.

2. Moreover, there is no special fastening effect around the male connector 100 and the female connector 200. When the user inserts the male connector 100 into the female connector 200 for connection, he often does not pay attention to the interspersed connection due to casual insertion. The tightness of the joint makes the connection loose, and the electrical signal is not easy to be transmitted between the male and female connectors.

In view of the above-mentioned shortcomings of the existing universal connector structure, the designer researched ways to improve these shortcomings. After tireless research and persistent development spirit, the utility model was finally produced.

Therefore, the utility model aims to provide an improvement of a universal connector. The elastic hook body is provided at both ends of the universal male connector shell. The edge wall of the female connector connected to the above-mentioned male connector corresponds to the barb of the elastic hook body of the male connector, and the locking part protrudes so that when the male connector is mated with the female connector, the pressing part can be pressed and the inverted The hook is connected to the locking part, thereby forming a fastening device around the connection, which can prevent the connected cables from being pulled off easily, causing the electrical signal in transmission to be cut off, which is the main purpose of the utility model.

According to the improvement of this kind of universal connector of the utility model, due to the fastening device arranged around it, it needs to be fully hooked when plugged in, so that the male connector and the female connector can be connected, which can further improve the inadvertent insertion of the connector. It is another purpose of this utility model to ensure that the electric signal is transmitted reliably.

Therefore, the technical solution of the utility model universal connector includes a male connector and a female connector. Elastic hook bodies are arranged on both sides of the male connector shell. part, while the edge wall of the female connector mated with the male connector protrudes with a locking part; the elastic hook body is provided with an upwardly protruding elastic top piece in the middle, and a downwardly protruding hook key, elastic The top piece pushes against the inner side of the channel of the male connector, and the hook key is used to extend into the preset hook hole in the channel of the male connector. device.

The technical scheme of the utility model forms a fastening device around the connection, which can prevent the connected cable from being easily pulled off, avoid the interruption of the transmission signal due to negligence and mistaken pulling and loosening, and can also prevent the male and female connectors from being interspersed in place. Situation happens.
