Assignee: M/A-COM Omni Spectra, Inc. (Waltham, MA)
Primary Examiner: Desmond; Eugene F.

Attorney, Agent or Firm: Hayes, Davis and Soloway
A solderless connector for semi-rigid coaxial cable having an elongate annular outer conductor, a center conductor coaxial with said outer conductor and a dielectric material spacing the inner and outer conductors apart, the connector comprising a housing having an annular portion defining a bore adapted to encompass said outer conductor and a bushing defining a bore to engage the exterior of the annular portion to circumferentially compress said annular portion upon telescoping movement of said bushing over said annular portion, said housing bore having, integral therewith, means adapted to engage said outer conductor upon said circumferential compression to provide a mechanical and electrical interface between said housing and said outer conductor. |

DETAILED DESCRIPTION We claim: 1.
A solderless connector for semi-rigid coaxial cable having an elongate annular outer conductor, a center conductor coaxial with said outer conductor and a di-electric material spacing the inner and outer conductors apart, the connector comprising a housing having an annular portion defining a cylindrical circumferentially continuous bore adapted to encompass said outer conductor and a substantially cylindrical circumferentially continuous bushing defining a bore to engage the exterior of the annular portion, the bushing bore being smaller in diameter than the outer diameter of said annular portion to an extent whereby upon telescoping movement of said bushing over said annular portion a desired circumferential compression of said annular portion occurs to produce desired radial inward deformation of said annular portion, said housing bore having, integral therewith, means adapted to engage said outer conductor upon said circumferential compression to provide a direct mechanical and electrical interface between said housing and said outer conductor, the substantially cylindrical bushing having a bore with about a 4.
degree.
taper from near the front end extending along a substantial part of its length to give a frusto conical compression of the housing with the largest diameter of the frustro conical commpression being closest to a coupling nut carried by the housing, said bushing having a relieved front end to permit initial jam fit with the exterior surface of the housing without substantial compression of the housing, whereby the housing, bushing and coupling nut in a preassembled unitary structure can be fitted over the end of the coaxial cable.
2.
A connector according to claim 1 wherein said housing includes a flange for holding the coupling nut.
3.
The connector of claim 1 wherein said bushing carries a seal at its rear end to form a weather tight seal with the outside of the coaxial cable.
Description:
The present invention relates to solderless connectors suitable for use with semi-rigid coaxial cable
