ABSTRACT:
A puncturing type cable coupling apparatus that is implemented either as a plug or a receptacle is disclosed. The basic structure of the cable coupling apparatus includes a shell member and abase member, wherein the base member has a pair of terminal bridges containing claws, corresponding to a pair of backing blocks provided on the shell member, such that an inserted cable will be slightly bent and clamped down between the respective claws and the backing blocks when the base member and the shell member are fitted together. The driving force on the base member allows the claws to puncture the insulation jacket of the cable to force electrical contact with the copper wire inside. The main advantage is that the cable coupling apparatus can be attached on ends of a cable with no need of stripping the insulation jacket before the installation.
