Abstract

A coaxial connector which includes a body, a nut threadably engaging the body and means operably upon engagement and tightening of the nut on the body which firmly engages the cable and makes a positive electrical contact. Moisture sealing means are included between the body and nut and between the nut and the cable to form a moisture-proof structure.

Claims

1. A connector for coaxial cable having an outer shield and a central insulated conductor with a portion extending from the shield comprising a hollow body having an externally threaded portion on one end thereof, slotted tubular insulating means within the said housing having a tapered end portion, a slotted female receptacle within the slotted tubular insulating means for receiving said extending central conductor portion, the other end of said body including an externally threaded portion and said receptacle including a conductive pin extending from said other end of said body, a collet within said body with at least one end of the opening in said collet being tapered and in engagement with the tapered portion of said insulating means, a nut threadably engaging said body and including cable gripping means through which said coaxial cable extends and means carried by said nut for sealing said cable in said nut and sealing means carried by said body for forming a seal between said body and said nut, said gripping means gripping said outer cable shield when said cable is inserted through the nut and the conductor portion is in engagement with said receptacle. whereby the inward displacement of the nut upon being tightened urges the end of said cable against said collet and displaces said collet inwardly, the inward movement of the collet forcing its tapered portion into tight engagement with the tapered portion of said insulating means thus reducing the diameter thereof and urging the walls of said receptacle into tight engagement with said conductor portion, and said gripping means in said nut further including a split metal collet having externally tapered end portion of the opening therein tapered to receive an end of said metal collet, said collars and metal collet being slidably retained with said nut, one of said collars engaging the end of said body when said nut is placed in threaded engagement therewith whereby tightening said nut decreases the distance between said collars and thereby effects a reduction in diameter of said split collet causing it to firmly grip the coaxial cable and make electrical contact therewith.

2. A connector according to claim 1 including an '"'"''"'"''"'"''"'"'0'"'"''"'"''"'"''"'"' ring disposed between said other collar and the end of said nut and a second '"'"''"'"''"'"''"'"'0'"'"''"'"''"'"''"'"' ring carried by said body at the inner end of said threaded portion.
