Abstract
Abstract Each grounding plate 31 or 32 includes main body 31b or 32b and grounding bars 31a or 32a which extend forward from the main body 31b or 32b. The grounding bars 31a or 32a and the signal lines Ce of coaxial cables are sandwiched between an insulation displacement piece 11 or 12 and the housing 10 to press the grounding bars 31a or 32a and the signal lines Ce into the insulation displacement portions Ta of the contacts T in the housing. The grounding plates 31 and 32 include barrels 33 to which the shielding wires Cc of the coaxial cables are connected for retaining the coaxial cables C in alignment such that the shielding wires Cc and the grounding bars 31a and 32a are electrically connected. In this way, an insulation displacement connector for coaxial cables is realized to make the connection of the coaxial cables to the contacts easy even for a multi-terminal connector and to prevent faults in the performance of the connector.

Claim 1
Independent Claim
267 words
An insulation displacement connector for connecting with a matable connector a plurality of coaxial cables, each cable incorporating a signal line and shielding wires, said insulation displacement connector comprising: a grounding plate which includes an elongate main body and grounding bars, said grounding bars extending transversely and forward from said main body; a plurality of contacts, each contact including an insulation displacement portion at one end to which said grounding bar or said signal line is squeezed to establish electrical connection therewith, and a contact portion at another end which is brought into contact with a contact of said matable connector; a housing, which retains said contacts in lateral alignment as a series extending in a longitudinal direction of the main body of the grounding plate; and an insulation displacement piece, which pushes said grounding bars and said signal lines to said insulation displacement portions; wherein: said main body also includes a connection retaining portion comprising a series of crimping ferrules located therealong to which said shielding wires are connected by crimping for retaining each said coaxial cable in alignment with each of said signal line extending transversely and forward from said main body and for establishing electrical connection between said shielding wires and said grounding bars, whereby both said grounding bars and said coaxial cables are maintained extending forward from said main body aligned in a row by the grounding plate so that the insulation displacement piece can push predetermined respective grounding bars and signal lines simultaneously into respective insulation displacement portion of said contacts to simultaneously establish electrical connection with respective contacts of the connector.
