Abstract

A permanent connector interconnects a hard-line coaxial cable to a connection housing. A contact is interconnected with and extends coaxially through a connector body. A collet one-piece with the contact receives a central conductor of the coaxial cable, while a sealing member and mandrel receive an outer conductor of the coaxial cable between them. A compression body positioned radially adjacent a portion of the connector body moves axially between first and second positions, wherein when the compression body is in its first position, the coaxial cable is removable from within the connector, and when the compression body is in its second position, the coaxial cable is not removable from within the connector. The compression body acts indirectly upon the sealing member so that an electrical connection is made between the sealing member and the outer conductor of the cable when the compression body is in its second position.

Claims

1. A device for interconnecting a hard-line coaxial cable to a connection housing, wherein said coaxial cable includes at least a central conductor, a layer of dielectric material covering the central conductor, and an outer conductor composed of hard-line material, said device comprising:

a connector body extending along a longitudinal axis;

a contact interconnected to and extending coaxially through said connector body;

for receiving said central conductor of said coaxial cable;

a compression body positioned radially adjacent a portion of said connector body for sliding axial movement relative thereto between first and second positions, wherein when said compression body is in its first position, said coaxial cable is removable from within said device;

a mandrel housed within said connector body; and

a sealing member housed within said connector body in continuous sealing relation to said outer conductor when said compression body is in its second position.

2. A device according to claim 1, further comprising a clamping member housed within said connector body, wherein a tapered surface of said clamping member directly engages a tapered surface of said compression body when said compression body is in its second position.

3. A device according to claim 2, further comprising a driving member housed within said connector body in ordered relationship between said clamping member and said sealing member such that when said compression body is moved from its first position to its second position, said compression body forces said clamping member against said driving member, and said driving member against said sealing member.

4. A device according to claim 3, further comprising a tapering surface on said sealing member which interacts with a tapering surface on said driving member by deforming said sealing member radially inward when said compression body is moved from its first position to its second position.

5. A device according to claim 4, wherein a radial distance between an inner diameter of said sealing member and an outer diameter of said mandrel is substantially equal to a radial distance between an inner diameter of said clamping member and said outer diameter of said mandrel.

6. A device according to claim 4, wherein said connector body is elongated beyond an amount required to contain said contact, said centering guide, said mandrel, said sealing member, said driving member, said clamping member, and said compression body.

7. A device according to claim 4, further comprising means for connecting said device to said connection housing, wherein said contact includes a conductive pin, and said connection housing is an equipment port.

8. A device according to claim 4, further comprising means for connecting said device to said connection housing, wherein said contact includes a solid end opposite said contact, and said connection housing is a male DIN connector.

9. A device according to claim 4, further comprising means for connecting said device to said connection housing, wherein said contact includes first and second collets, and said connection housing is a female DIN connector.

10. A device according to claim 4, further comprising means for connecting said device to said connection housing, wherein said connection housing is a hardline coaxial cable.

11. A device according to claim 4, wherein said portion of said compression body radially adjacent said connector body is inside said connector body.

12. A device according to claim 4, wherein a radial distance between an inner diameter of said sealing member and an outer diameter of said mandrel is less than a radial distance between an inner diameter of said clamping member and said outer diameter of said mandrel.

13. A device according to claim 12, further comprising:

a first annular groove in an outer surface of said compression body;

a second annular groove in an inner surface of said compression body;

a first O-ring in said first annular groove; and

a second O-ring in said second annular groove, wherein when said compression body is in its second position, said first O-ring forms a seal between said compression body and said connector body and said second O-ring form a a seal between said compression body and said coaxial cable.

14. A device according to claim 4, further comprising a centering guide having a first portion coupled to said contact and a second portion engaging a portion of said mandrel, and having a third portion between said first and second portions which guides said central conductor into said contact upon insertion of said central conductor into said connector body.

15. A device according to claim 14, further comprising:

an annular groove in an outer surface of said compression body; and

an O-ring in said annular groove, wherein when said compression body is in its second position, said O-ring forms a seal between said compression body and said connector body.

16. A device according to claim 4, wherein said portion of said compression body radially adjacent said connector body is outside said connector body.

17. A device according to claim 16, wherein said mandrel includes a tapered end coupled to said contact and a bushing which guides said central conductor into said contact upon insertion of said central conductor into said connector body.

18. A device according to claim 16, further comprising a seizure/bushing member with a seizing end coupled to said contact and a bushing end coupled to said mandrel, wherein said bushing guides said central conductor into said contact upon insertion of said central conductor into said connector body.

19. A device according to claim 18, further comprising a spring inside said connector body which biases said seizure/bushing member away from said contact.

20. A device for interconnecting a hard-line coaxial cable to a connection housing, wherein said coaxial cable includes at least a central conductor, a layer of dielectric material covering the central conductor, and an outer conductor composed of hard-line material, said device comprising:
