  • Publication number: 20240145980
    Abstract: A cable connector includes a metal housing, an insulator, and a cable. The metal housing includes a sleeve end, a main body, and a plug end integrally formed from rear to front. The plug end includes an end body having a plurality of holes formed therethrough, a ring portion extending forward from the end body, and a plurality of elastic elements extending backward from the ring portion. The cable is accommodated in the metal housing and fixed to the insulator. Therefore, by the metal housing integrally formed, the manufacturing steps and the assembly steps of the cable connector are simplified. Furthermore, by the design that each elastic element extends backward from the ring portion, the deformation of each elastic element due to the excessive stress during plugging is avoided.
