A cable plug connector for an insulated coaxial cable:
- the cable comprises an internal conductor, a dielectric layer outside the internal conductor and supporting an external conductor, a thin metallic external conductor positioned around and supported on the dielectric layer, and an external protective casing of insulating material around the external conductor;
- an annular section of the cable casing is removed to faciliate electrical and mechanical contact with the exposed contact section of the external conductor;
- said connector comprising:
- a resilient spring electric contact ring extending around the contact section of the external conductor;
- said contact ring having a supported edge portion extending toward a clamping sleeve and having an opposite free edge portion opposite its said supported edge portion;
- said contact ring being so shaped and oriented that its said free edge portion is normally raised above the contact section of the external conductor and its said free edge portion is radially deflectable inwardly against the contact section of the external conductor;
- a contact sleeve having an opening therein into which the cable and said contact ring are movable and which said contact sleeve opening is defined by a contact sleeve opening wall;
- said contact ring being movable into said contact sleeve opening, said contact sleeve opening wall being shaped to engage and cause said contact ring free edge portion to deflect radially inwardly as said contact sleeve is moved toward the clamping sleeve and moved toward and into engagement with a gripping sleeve and this causes said contact ring free edge portion to engage the contact section of the external conductor;
- a gripping sleeve over the cable extending toward and meeting with said contact sleeve and also extending over said connector;
- said gripping sleeve being shiftable on and toward said contact sleeve such that said gripping sleeve and said contact sleeve engage and move together a predetermined distance once they engage;
- a gripping sleeve opening formed in said gripping sleeve for receiving the cable and for receiving a clamping sleeve and having a gripping sleeve opening wall defining said gripping sleeve opening;
- said gripping sleeve opening facing toward said contact sleeve opening;
- a resilient clamping sleeve having a supported edge portion which is connected with and supported together with said supported edge portion of said contact ring;
- said clamping sleeve extending away from said contact ring and extending around the cable casing;
- said clamping sleeve being shaped and oriented to extend into and being movable into said gripping sleeve opening;
- said clamping sleeve being slit into a plurality of tongues all extending into said gripping sleeve opening;
- said clamping sleeve tongues having a free edge portion, opposite said clamping sleeve supported edge portion, and said free edge portion is normally raised above the cable and is radially deflectable inwardly against the cable casing;
- said gripping sleeve opening wall being shaped to engage and cause said clamping sleeve free edge portion to deflect radially inwardly as said gripping sleeve is moved toward and on said contact sleeve and to cause said clamping sleeve to thereby engage the cable casing.
