Abstract: A mini-coaxial cable connector includes a metal case having a cylindrical sleeve, two horizontally extended restricting arms, and a bendable clamping section having several pairs of clamping plates; an insulating seat having a hollow body located in the cylindrical body of the metal case, a holding-down strip, and a cable holder opposite to the holding-down strip and having the same length as that of the restricting arms for fitly locating in and between the restricting arms; and a contact terminal having two downward contact plates located in the hollow body and two horizontally staggered upward riveting plates for enclosing and riveting a center conductor of a coaxial cable. When the clamping section is bent, the pairs of clamping plates separately clamp around the cylindrical sleeve, the restricting arms, and the coaxial cable. And, the clamping plates clamping the restricting arms define a five-face damper having one open side.
