Cable connector

The present invention relates to a cable connector, and more particularly to a cable connector configured with a locking mechanism.

With the development trend of miniaturization and multi-functionality of electrical equipment, the requirements for cable connectors are increasing day by day, which not only requires strong signal transmission capability, but also requires a pair of connectors that are connected to each other to be detached (unlocked). Convenience features for better application in a variety of complex applications.

Chinese Patent No. ZL200420022197.0 discloses a cable connector that is unlocked from top to bottom. The cable connector includes an insulative housing, a plurality of conductive terminals interposed on the insulative housing, a metal mask housing disposed on the outer circumference of the insulating body, and a metal inner sleeve sleeved at a rear end of the insulating body An insulating housing, two hooks mounted between the two sides of the insulating body and the inner side wall of the metal inner casing, and a bead for fixing the hook. The hook has a fixing portion fixed on the insulating body and a resilient arm movable up and down relative to the fixing portion, and a front end of the elastic arm of the hook protrudes upwardly, and the barb passes through the metal cover The through hole of the upper surface of the cover shell protrudes upward to be hooked with the other mating connector socket, thereby ensuring the solid connection between the two connectors. The resilient arm of the hook is further provided with a bump for contacting the pressing portion on the insulating housing. When the cable connector is unlocked with another docked connector socket, the spring is required to be pressed from above the cable connector, and the barb is driven to move downward.

The hooks of the above cable connectors are respectively installed on both sides of the insulating body, and need to have a large lateral size. The shrapnel is in contact with the two hooks at the same time, and it is necessary to apply a large force to press the shrapnel. In addition, the above cable connector has a complicated structure and is not easy to manufacture.

Therefore, it is indeed necessary to improve the cable connector to solve the above problems.
