Abstract

A multiple coaxial cable plug connection (50), particularly for the detachable connection of a plurality of coaxial cables to a circuit board for operating frequencies of several GHz, comprises a first connector (10) and a second connector (20), wherein said connectors (10, 20) can be inserted in each other along a plug axis, wherein the first connector (10) has a plurality of first coaxial contact arrangements (26) disposed next to each other transversely to the plug axis, and the second connector (20) is equipped with second coaxial contact arrangements (27) that match the first coaxial contact arrangements (26), and wherein the first coaxial contact arrangements (26) each are attached to the end of an associated coaxial cable. High precision of the connection, and at the same time a reduced insertion force, are achieved in such a multiple coaxial cable plug connection in that the first coaxial contact arrangements (26) are floatingly supported in a first housing (11), while the second coaxial contact arrangements (27) are permanently installed in a second housing (21).

4. The multiple coaxial cable plug connection as claimed in claim 1, wherein the first coaxial contact arrangements (26) mounted in a floating manner in the first plug connector (10) are inserted transverse to the plug axis (51) to latch into a bearing plate (18), and the bearing plate (18) is held with radial play in the first housing (11).

5. The multiple coaxial cable plug connection as claimed in claim 4, wherein the bearing plate comprises a comb (18) with outwardly projecting teeth (19;

19a,b), with accommodation spaces (25) for accommodating the inserted first coaxial contact arrangements (26) being arranged between said teeth.

6. The multiple coaxial cable plug connection as claimed in claim 5, wherein the first coaxial contact arrangements (26) have a cylindrical shape, and the accommodation spaces (25) comprise a round accommodation section (25a), of which the diameter is generally matched to the first coaxial contact arrangement (26), and a straight insertion section (25b) which connects the accommodation section (25a) to the exterior and includes a width (b) slightly smaller than the diameter (D) of the accommodation section (25a), the first coaxial contact arrangement (26) insertable through the insertion section (25b) to latch into the accommodation section (25a).

7. The multiple coaxial cable plug connection as claimed in claim 6, wherein the first coaxial contact arrangement (26) includes a peripheral latching groove (30) having an outside diameter matched to the diameter (D) of the accommodation section (25a).

8. The multiple coaxial cable plug connection as claimed in claim 4, wherein the first housing (11) includes an interior (12) which proceeds in the direction of the plug axis (51) and is open at the ends, wherein one of the bearing plate and the comb (18) is held with play in recesses (13, 14, 15) in the first housing (11).
