Connector for coaxial cable
First Claim
1. An microwave connector assembly comprising:
- a terminating flexible microwave coaxial cable including an inner conductor, an intermediate dielectric, an outer flexible braided conductor, and an outer insulator;
a bored interface body having a first end with a first bore of relatively large inner diameter, a second end with a second bore of relatively smaller inner diameter than said first bore, and a third bore located therebetween of relatively smaller inner diameter than said second bore;
a coupling member proximate said interface body;
an annular locking member having an inside surface sized to receive said coaxial cable therein and bonded by means of a bonding agent to said outer insulator thereof, an outer diameter sized to fit tightly within said first bore of said interface body, a first end and a second end, said second end having a plurality of ribs disposed proximate thereto, so that upon insertion of said second end of said locking member within said first bore of said interface body, said ribs frictionally engage the inner wall of said first bore to lock said locking member to said interface body;
wherein said bonding agent is a high flexural strength rigid epoxy resin that eliminates movement between said coaxial cable and said annular locking element and provide a pull strength in excess of 10 pounds and antirotational captivation up to ±
90 degrees for multiple mating and demating cycles.

Abstract
An electrical connector for terminating flexible coaxial cable is provided. The flexible coaxial cable includes an inner conductor, an intermediate dielectric, an outer flexible braided intermediate dielectric and an outer insulator. A bored interface body has a first end with a first bore of relatively large inner diameter and a second end with a second bore of relatively smaller inner diameter than the first bore. A coupling member is located proximate to the interface body. An annular locking member having an inner diameter sized to receive the coaxial cable therein and an outer diameter sized to fit tightly within the first bore of the interface body. The locking member is bonded to the coaxial cable, which, in construction, is pre-conditioned to accept a bonding agent such as an epoxy resin.
