Claims
- 1. For use in providing electrical connection to a coaxial cable without signal interruption thereto and wherein the coaxial cable has a center conductor, an outer conductor and a dielectric therebetween, and said cable has a longitudinal axis, apparatus comprising:
- a cable connector clamp including:
- a base plate;
- a lower shoe removably disposed in the base plate;
- the base plate and lower shoe having an elongated recess for acceptance of a coaxial cable therealong;
- first and second end pieces removably attached to the base plate in spaced relation for retaining the coaxial cable in the elongated recess;
- the portion of the coaxial cable between the end pieces being disposed for access;
- a cutting block disposable in the portion between the end pieces and including fastener means for removably securing the cutting block to the base plate;
- the cutting block having a transverse opening therethrough, extending along an axis orthogonal to the axis of the coaxial cable disposed in the cable connector clamp, and intersecting the outer conductor of the coaxial cable and a portion of the dielectric material between the outer conductor and the center conductor of the coaxial cable;
- the transverse opening of the cutting block being operative to receive and guide a cutting tool insertable through the opening and operative to remove a portion of the outer conductor and a portion of the dielectric between the outer conductor and center conductor of the coaxial cable without contacting the center conductor of the coaxial cable;
- a top piece disposable in the portion between the end pieces of the connector clamp after removal of the cutting block and including fastener means for securing the top piece to the lower shoe for retention of the coaxial cable between the top piece and lower shoe, said top piece including means for providing electrical connection to the outer conductor;
- a coaxial connector fitting secured to the top piece and having a center pin extending through the dielectric in the removed area of the cable to radially engage the center conductor of the cable;
- the base plate and end pieces being removable from the cable after securing the top piece and lower shoe to the cable.
- 2. The apparatus of claim 1, wherein
- said transverse opening and cutting tool each have a surface curved about an axis offset from the center conductor of the coaxial cable for removing a concave portion of said dielectric.
- 3. The apparatus of claim 2 wherein the base plate has a centrally disposed opening configured to receive the lower shoe;
- the end portions of the base plate and lower shoe having elongated recesses therealong which form a continuous recess with the lower shoe disposed in the base plate for acceptance of the coaxial cable.
- 4. The apparatus of claim 3 wherein the lower shoe includes one or more threaded openings disposed outwardly of the recess;
- wherein the cutting block includes one or more openings therethrough cooperative with the threaded openings of the lower shoe for acceptance of threaded fasteners; and
- wherein the top piece includes one or more openings therethrough in alignment with the threaded openings of the lower shoe for acceptance of threaded fasteners.
- 5. The apparatus of claim 1 wherein the coaxial connector fitting includes a threaded outer portion for mating with a standard coaxial connector.
- 6. The apparatus of claim 1 wherein the coaxial connector fitting includes a center pin having at the distal end thereof a pair of spaced tips spaced to engage the center conductor.
- 7. The apparatus of claim 6 wherein the tips of the center pin are operative to displace the dielectric material of the coaxial cable.
- 8. The apparatus of claim 7 wherein the tips of the center pin each have plural knife edges to mechanically and electrically engage confronting portions of the center conductor.
- 9. The apparatus of claim 8 wherein the tips of the center pin are operative to provide self-aligning of the center pin to the center conductor.
- 10. The apparatus of claim 1 wherein the top piece has a plurality of outwardly extending pins operative to pierce the outer conductor of the coaxial cable retained between the top piece and lower shoe for providing electrical connection to the outer conductor.
- 11. The apparatus of claim 1 wherein the coaxial connector fitting includes a first portion threaded to mate with a threaded opening through the top piece.
- 12. Apparatus for providing connection to a coaxial cable, comprising:
- a lower shoe permanently retaining a longitudinal portion of said coaxial cable;
- a cutting block temporarily mating with said lower shoe to retain said cable therebetween, the cutting block having a transverse opening therethrough, extending along an axis orthogonal to the axis of the coaxial cable disposed in the lower shoe, and intersecting the outer conductor of the coaxial cable and a portion of the dielectric material between the outer conductor and the center conductor of the coaxial cable, the transverse opening of the cutting block being operative to receive a cutting tool insertable through the opening and operative to remove a portion of the outer conductor and a portion of the dielectric between the outer conductor and center conductor of the coaxial cable without contacting the center conductor of the coaxial cable;
- means for temporarily retaining said lower shoe and said cutting block in mating relationship; and
- a top piece disposable to permanently mate with said lower shoe after removal of the cutting block, and including fastener means for securing the top piece to the lower shoe for retention of the coaxial cable between the top piece and lower shoe, said top piece including means for providing electrical connection to said outer conductor and means for providing electrical connection to said inner conductor.
- 13. A coaxial cable connector for providing electrical connection to a coaxial cable without signal interruption thereto, comprising:
- a cable cutter guide having an elongated recess which peripherally intersects the coaxial cable and through which a cable cutter moves to remove a peripheral portion of said coaxial cable;
- a cable shoe;
- means for retaining said cable shoe in alignment with said cable cutter guide;
- a connector top piece for matingly engaging said cable shoe about the cable; and
- a cable center conductor tap retained by said connector top piece to radially engage the center conductor of said coaxial cable at an angle orthogonal to said recess.
