Coupling for coaxial cables
A connector interconnect two coaxial cables each having a central conductor surrounded by an outer conductor. A respective connector piece is assigned to each coaxial cable. The invention ensures the easy and rapid use of the connector, while reliably guaranteeing the electrical contact between the interconnected coaxial cables. To achieve this, each connector piece has one connection region that is electrically connected to the respective central conductor of the corresponding coaxial cable, a connection head of the second connector piece being supported on the connection region of said piece by means of a spring element, in order to make electrical contact with the connection region of the first connector piece.
1. A coupling for connecting two coaxial cables to one another, each of the coaxial cables having a central conductor surrounded by an outer conductor, the coupling comprising:
first and second coupling pieces each associated with a respective coaxial cable and each having a connecting area electrically connected to the central conductor of the respective coaxial cable;
a connection head movably mounted on said second coupling piece for producing electrical contact with said connecting area of said first coupling piece, and a spring element supporting said connection head on said connecting area of said second coupling piece;
said connection head ending in a number of contact fingers which are inserted into recesses formed in said connecting area of said second coupling piece, said connecting area of said second coupling piece being provided with a contact piece having an associated connecting surface for at least one of said contact fingers.
2. The coupling according to claim 1 , wherein said contact piece is formed with a connecting surface for each of said contact fingers.
3. The coupling according to claim 1 , wherein said connection head and said connecting area of said first coupling piece are formed with contact surfaces having matching shapes such that said connection head is self-centered about said connecting area of said first coupling piece relative to a longitudinal axis of the coupling when the coaxial cables are coupled to one another.
4. The coupling according to claim 1 , wherein said connection head is formed with a tip having a truncated cone shape and corresponding with a conical recess formed in said connecting area of said first coupling piece.
5. The coupling according to claim 1 , which further comprises a retaining screw holding said connection head on said connecting area of said second coupling piece.
6. The coupling according to claim 1 , which further comprises a mounting flange for the outer conductor surrounding the respective said connecting area of each of said first coupling piece and said second coupling piece.
7. The coupling according to claim 6 , which further comprises a circumferential seal disposed between said mounting flanges.
8. The coupling according to claim 6 , which further comprises a common closure element surrounding said mounting flanges in a mated state thereof.
9. The coupling according to claim 8 , which further comprises a circumferential seal introduced between said mounting flanges.
10. The coupling according to claim 8 , wherein said mounting flanges are surrounded by a common closure element in a mated state thereof.
11. The coupling according to claim 10 , wherein said common closure element comprises a clamping ring and a spring clip.
