Abstract

A compression-type coaxial cable connector having a male adapter nut at the leading end thereof, a slotted body portion and a compression sleeve slidably attached to the body portion and forming the trailing end of the connector. The connector, and each of the components associated therewith, has an axial conduit coextensive with the length thereof. The prepared end of a coaxial cable is inserted into the trailing end of the axial conduit and advanced through the conduit into the body portion until the center conductor of the cable either extends into the adapter nut or is seized by a fixed seizing pin that extends through the leading end of the adapter nut, and the compression sleeve advanced over the body portion to complete the connection. The connector, which, unlike prior art connectors, lacks a center post, is easy to install and is suitable for low frequency (<˜20 MHz) applications.

Claims

1. A coaxial cable connector having an axial conduit coextensive with a length thereof, the connector being operable for coupling an electrically conductive pin attached to a center conductor of a coaxial cable to a receiving port to provide an electrical connection between the center conductor and the receiving port, said connector consisting essentially of:

(a) a cylindrical body portion having a no portion that enters axially into the coaxial cable a leading end and a trailing end and a central conduit dimensioned to receive the coaxial cable;

(b) an adapter nut rotatable attached to said leading end of said body portion, said adapter nut having an axial conduit adapted to receive a leading end of the conductive pin therewithin, said adapter nut being operable for matingly engaging the receiving port; and

(c) a cylindrical compression sleeve slidably attached to said trailing end of said body portion.

2. The coaxial cable connector of claim 1 wherein said body portion has at least one slot in a trailing end thereof.

3. The coaxial cable connector of claim 2 wherein an inner diameter of said compression sleeve adjacent a trailing end thereof is less than said inner diameter at a leading end of said compression sleeve.

4. The coaxial cable connector of claim 3 wherein said compression sleeve has an annular ridge on an inner surface thereof and wherein said body portion has a forward annular locking groove and a rearward annular locking groove on an outer surface thereof and wherein said annular ridge engages said rearward annular locking groove on said outer surface of said slotted body portion to slidably attach said compression sleeve to said body portion.

5. The coaxial cable connector of claim 4 wherein when said compression sleeve is advanced toward said leading end of said body portion, said trailing end of said body portion is forced radially inwardly and said annular ridge on said inner surface of said compression sleeve lockingly engages said forward locking groove on said outer surface of said body portion.

6. A coaxial cable connector having an axial conduit coextensive with a trailing portion thereof, the connector being operable for coupling an end of a coaxial cable having a center conductor to a receiving port to provide an electrical connection between the center conductor of the coaxial cable and the receiving port, said connector consisting essentially of:

(a) a cylindrical body portion having a no portion that enters axially into the coaxial cable a leading end and a trailing end;

(b) an adapter nut rotatable attached to said leading end of said body portion, said adapter nut being operable for matingly engaging the receiving port;

(c) a seizing pin rigidly mounted within said adapter nut, said seizing pin being electrically insulated from said adapter nut and having a leading end projecting forwardly from a leading end of said adapter nut and a hollow trailing end, said hollow trailing end being adapted to receive and lockingly engage the center conductor; and

(d) a cylindrical compression sleeve having a cylindrical axial conduit with an inner diameter therewithin slidably attached to said trailing end of said body portion.

7. The coaxial cable connector of claim 6 wherein said body portion has at least one slot in a trailing end thereof.

8. The coaxial cable connector of claim 7 wherein said inner diameter of said axial conduit within said compression sleeve adjacent a trailing end thereof is less than said inner diameter at a leading end of said axial conduit within said compression sleeve.

9. The coaxial cable connector of claim 8 wherein said compression sleeve has an annular ridge on an inner surface thereof and wherein said body portion has a forward annular locking groove and a rearward annular locking groove on an outer surface thereof and wherein said annular ridge engages said rearward annular locking groove on said outer surface of said slotted body portion to slidably attach said compression sleeve to said body portion.

10. The coaxial cable connector of claim 9 wherein when said compression sleeve is advanced toward said leading end of said body portion, said trailing end of said body portion is forced radially inwardly and said annular ridge on said inner surface of said compression sleeve lockingly engages said forward locking groove on said outer surface of said body portion.
