Abstract

The connector system includes a coupling bush in each of whose openings on both sides a multiway connector, each with a connector housing, can be inserted. A plurality of individual plug connectors having alignment elements are mounted in a floating manner in each connector housing. Alignment aids on the connector housings lead during the mating process and directly align the connector housings with respect to one another before the alignment elements of the individual plug connectors start to cooperate, with mutual fine alignment. The two housings have the same alignment aids which are disposed such that, when one of said multiway connectors is rotated through 180° about its longitudinal axis with respect to the other one, the alignment aids are aligned to cooperate with one another and to allow the two connectors to mate.

Claims

1. An optical connector system, comprising:

two multiway connectors each having a connector housing with a longitudinal axis and a plurality of individual plug connectors float-mounted in said connector housing;

a plurality of alignment aids on said connector housings and an individual alignment element on each of said individual plug connectors;

said connector housings having a face edge, and said alignment aids being a plurality of long tab-shaped projections and a plurality of short tab-shaped projections on said face edge of said connector housing, said connector housings of said two multiway connectors being provided with substantially identical alignment aids disposed such that, when one of said multiway connectors is rotated through 180°

about the longitudinal axis thereof with respect to the other one of said multiway connectors, said long tab-shaped projections cooperate with said short tab-shaped projections; and

a coupling bush for axially fixing said housings of said two connectors to one another in a mating position thereof.

2. The connector system according to claim 1, wherein each of said connector housings has a longitudinal edge, a top, and a bottom, and said plurality of long tab-shaped projections and said plurality of short tab-shaped projections are arranged on said longitudinal edges, and at least one of said long tab-shaped projections and at least one of said short tab-shaped projections are arranged in a central area of said top and said bottom of said connector housing.

3. The connector system according to claim 2, wherein said short tab-shaped projections on said longitudinal edges are provided with a rectangular L-shaped cross section.

4. The connector system according to claim 2 or 3, wherein said at least one long tab-shaped projection in said central area forms a projection on said connector housing, and said at least one long tab-shaped projection cooperates with a groove of said coupling bush.

5. The connector system according to claim 1, wherein said two connectors are mateable in a defined mating direction, and at least one of said alignment aids forms a limit stop to a movement of said connector housing in at least two degrees of freedom at right angles to the mating direction.
