Coaxial connector and method for connecting the coaxial connector to a mating component
View Patent ↗A coaxial connector comprises a swivel member defining a central axis and having first and second opposing ends. The first end having an outer and an inner surface and a threaded region for threadingly engaging the first end of the swivel member with a matching threaded portion of a mating component. A main body having first and second opposing body ends and a central bore defining a longitudinal axis which is coaxial with the central axis of the swivel member. The first body end having an outer cylindrical surface, a centre conductor extending along the longitudinal axis and a nut having a central aperture defining an inner surface and first and second opposing side walls. The first side wall being adapted to slidingly engage and abut the mating component and an inner inclining surface region.
1. A coaxial connector for connecting a coaxial member to a mating component, comprising:
a swivel member defining a central axis and having first and second opposing ends, the first end having an outer and an inner surface and a threaded region for threadingly engaging the first end of the swivel member with a matching threaded portion of the mating component;
a main body having first and second opposing body ends and a central bore defining a longitudinal axis which is coaxial with the central axis of the swivel member, the first body end having an outer cylindrical surface;
a centre conductor extending along the longitudinal axis and,
a nut having a central aperture defining an inner surface and first and second opposing side walls, the first side wall being adapted to slidingly engage and abut the mating component , and an inner inclining surface region, wherein the swivel member extends through the central aperture of the nut, the inner surface of the nut engaging with a region of the swivel member to prevent substantial rotation of the nut in relation to the swivel member, wherein the swivel member is rotatably received on the outer cylindrical surface of the first body end of the main body and the outer cylindrical surface is adjacent to a recessed region so as to form a shoulder, and wherein the second end of the swivel member has an inwardly extending projection and an outer inclining surface region and is radially compressible, the inner inclining surface region of the nut being adapted to cooperate with the outer inclining surface region of the swivel member so as to radially compress the second end of the swivel member in order to bring the inwardly extending projection into engagement with the shoulder.
2. A coaxial cable connector according to claim 1 , wherein the second end of the swivel member comprises at least one slit in order to allow the second end of the swivel member to be compressed.
3. The coaxial cable connector according to claim 2 , wherein a part of the outer surface of the second end of the swivel member has a conical outline.
4. A coaxial connector according to claim 3 , wherein the at least one slit of the second end of the swivel member extends through the surface having a conical outline.
5. A coaxial connector according to claim 4 , wherein the outer surface of the second end of the swivel member comprises an area having opposing flats for receiving the inner surface of the nut.
6. A coaxial connector according to claim 5 , wherein the at least one slit of the second end of the swivel member extends through an area having opposing flats.
7. A coaxial connector according to claim 6 , wherein the swivel member comprises an area on the outer surface that is adapted to carry a first sealing member.
8. A coaxial connector according to claim 7 , wherein the area on the outer surface of the swivel member adapted to carry the first sealing member is placed between the threaded region of the swivel member and the region of the swivel member having opposing flats.
9. A coaxial connector according to claim 8 , wherein the coaxial connector further comprises a second sealing member placed in a slot in the main body.
10. A coaxial connector according to claim 1 , wherein the coaxial connector is substantially made of a conductive material.
11. A coaxial connector according to claim 10 , wherein the conductive material is brass or plated brass.
12. A coaxial connector according to claim 11 , wherein the outer surface of the second end of the swivel member comprising a conical-shaped area is forced essentially radially towards the longitudinal axis of the main body when a longitudinal force is subjected to the nut.
13. A coaxial connector according to claim 12 , wherein in an uncompressed state, the diameter of the second end of the swivel member and thereby the inwardly extending projection has a larger diameter than in its compressed state.
14. A coaxial connector according to claim 13 , wherein in the compressed state, the inwardly extending projection of the second end of the swivel member extends toward the longitudinal axis of the main body in a smaller diameter than an outer diameter of the shoulder of the main body, thereby locking the swivel member to the main body.
15. A coaxial connector according to claim 14 , wherein the swivel member is made of a flexible material able to expand when the inwardly extending projection is slid past the shoulder, and to subtract when the inwardly extending projection has been slid past the shoulder.
