Abstract

A coaxial cable connector including a screw threaded tube, a male clamping tube and a female clamping tube. The male clamping tube has a central hole, a rear projection pipe and a clamping portion, whereby an insulating portion of a concentric coaxial cable fits into the projection pipe with an outer cover and separate grounding wire sheath of the concentric coaxial cable fitted between the projecting pipe and clamping portion. The inner wall of the female clamping tube is formed with rearwardly tapering inclined portion whereby when the female clamping tube is fitted to the male clamp portion, the tapering portion presses the clamping section of the male clamping tube making the saw tooth portion of the inner wall of the clamping portion securely bite into the concentric coaxial cable. An annular projecting shoulder formed on an outer wall of the clamping portion of the male clamping tube engages an annular groove formed on inner wall of the female clamping tube to join the male and female clamping tubes. The joined clamping tubes are fitted into the screw threaded tube having threads on an inner wall formed to thread on a coaxial cable socket with an axial connecting wire of the coaxial cable passing through the male clamping tube into an output hole of the coaxial cable socket.

Claims

1. A coaxial cable connector, comprising:

a male clamping tube having a central hole and a rear projecting pipe, said male clamping tube having an inner diameter slightly larger than the outer diameter of an insulating portion of a concentric cable, and a rear clamping portion having several circularly arranged clamp sections extending rearward, the front ends of said clamp plates being formed with an annular groove so that said clamping section can be deformed and inwardly deflected;

an annular projecting shoulder inwardly and rearwardly inclined, formed on said clamping sections, the rear ends of said clamp sections having an inwardly and rearwardly inclined face, the inner walls of said clamp plates being formed with a saw tooth portion;

a female clamping tube having a rearwardly tapered interior surface and an annular groove; and

a screw threaded tube housing having threads formed on an inner wall of the front end, said screw threaded tube housing receiving and enclosing said male and female clamping tubes, an inward extending flange being formed at rear end of said screw threaded tube, said flange having an inner diameter smaller than outer diameters of said male and female clamping tube but larger than outer diameter of a coaxial cable, whereby when assembled, said screw thread tube and female clamping tube and male clamping tube are sequentially fitted over said coaxial cable with said insulating portion inserted into said projecting pipe and an axial wire of said coaxial cable protruding beyond front end of said male clamping tube, said female clamping tube engaging said clamping portion of said male clamping tube to press said clamping section until said annular projection engages said annular groove of said female clamping tube locking said male and female clamping tubes on said coaxial cable.

2. A connector for coaxial cables comprising:

a male clamping tube having a pipe portion slotted to form a plurality of clamping sections, said pipe portion having a diameter for fitting over the insulating core and under the grounding earth of a coaxial cable;

a female clamping tube having mating with said male clamping tube, said female clamping tube having an inner tappered surface for pressing said clamping sections inward against said coaxial cable;

looking means for looking said male clamping tube and said female clamping to be together with said clamping sections gripping said coaxial cable;

a tubular housing having threads in on end and a retaining flange at the opposite end, said tubular housing constructed to fit around said mated male and female clamping tubes with said retaining flange abutting a rearward end of said female clamping tube;

whereby when said tubular housing is threaded onto a threaded coaxial cable socket, said male and female clamping tubes an axial forced together clamping said clamping sections on said coaxial cable until said locking means is engaged.

3. The connector according to claim 2 in which;

said male clamping tube clamping section is slotted to form four equal clamping sections.

4. The connector according to claim 3 in which said tubular housing has wrench flats formed on its external surface for use with a standard wrench.

5. The connector according to claim 2 in which said locking means comprises;

a projecting shoulder on said clamping section of said male clamping tube engaging an annular groove in the interior of said female clamping tube.
