Abstract
Abstract A plug for coaxial cable of the type used for wire broadcasting transmission or multiplex communication system comprising a shielding cap. The shielding cap molded from a conducting material is connected to the cable without stripping the outer insulating material because several sharp-edged sector-shaped projections formed at the end of the shield cap penetrate into the outer insulation of the cable and their tips stick in the shielding net of the cable. A socket or other contact elements of other electrical circuits may or may not have a thread for engaging the assembled plug since the shielding cap itself is made of an elastic material which allows sliding fit instead of thread engagement.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
180 words
A plug for connecting, a coaxial cable of the type having a core wire, an insulating material enclosing the core wire, a shielding net and an outer insulation, to a socket or other contact elements of other electrical circuits, which comprises: an outer casing having two halves connected by a connector member therebetween, each half having a smaller and a larger semi-cylindrical wall and two interlocking means, said larger wall having a core wire supporting member vertically projected from about a middle part thereof; a shielding cap having two halves smaller than said outer casing, each half of said shielding cap having a smaller and a larger semi-cylindrical wall, said smaller wall providing a hole for receiving some lengths of unstripped cable and said larger wall providing a hole for receiving a socket thread or the like with sliding fit and having said core wire supporting member being vertically projected therethrough when mounting within said outer casing; and several radially formed sector-shaped projections having sharp edges and being formed at the end of each smaller wall of said shielding cap.
