Abstract

A connector for coupling an optical cable including at least one optical fiber terminated in an optical contact to a phototransducer device is disclosed. A swivel member mounts the optical contact with a terminal end of the contact adjacent to an inner side of the swivel member. The swivel member is received within a connector body and is movable therein. A base member mounts the photo-transducer device with the photo-transducer accessible from an inner side of the base member. Mating surfaces are formed on the inner sides of the swivel and base members, to guide the terminal end of the contact and the photo-transducer device into alignment as the connector body is moved to a connected position adjacent to the base member. Biasing means between the connector body and the swivel member urges the swivel member toward the base member and allows the swivel member to align itself with the base member. Means are also provided for securing the connector body in the connected position. This construction provides an accurate and readily separable connection between the optical contact and the photo-transducer device. In one aspect, a swing arm arrangement provides general registration between the swivel and base members to facilitate accurate alignment between the contact and photo-transducer device.

Claims

1. A connector for coupling an optical cable terminated in an optical contact to a first photo-transducer device supported by a circuit board which is held within a rack, comprising:

a base member connected to said circuit board for mounting said first photo-transducer with said first photo-transducer in optical communication with an inner side of said base member;

a swivel member for mounting said optical contact with a terminal end of said optical contact adjacent to an inner side of said swivel member;

a connector body defining a cavity for loosely receiving said swivel member to allow said swivel member to move axially and angularly within said connector body;

means for pivotally connecting said connector body to said rack to allow swinging said connector body to move the inner side of said swivel member into general registration with the inner side of said base member;

mating surfaces formed on said inner side of said swivel member and on said inner side of said base member to guide said terminal end of said optical contact and said first photo-transducer into accurate alignment as the connector body is swung to a connected position;

biasing means between said connector body and said swivel member to urge said swivel member toward said base member and to allow said swivel member to accurately align itself angularly and axially with said base member; and

means for securing said connector body in said connected position.

2. A connector as in claim 1, wherein:

the base member is connected to the circuit board adjacent to an edge of the circuit board; and

a portion of the edge of the circuit board is provided with electrical contact pads; and

further comprising;

a transducer assembly including (a) a second photo-transducer device, (b) electrical contact means connected to said second photo-transducer device which are suitable to provide a readily separable connection with said electrical contact pads, and (c) means for coupling an optical contact to said second photo-transducer device; and

means on said connector body for mounting said transducer assembly with said electrical contact means engaging said electrical contact pads when said connector body is swung to the connected position.

3. A connector as in claim 2, wherein:

the connector body houses a plurality of swivel members and a biasing means for each swivel member;

a similar plurality of base members, each mounting a first photo-transducer device, are provided in an integral base module; and

a plurality of transducer assemblies are provided with a similar plurality of means on said connector body for mounting said transducer assemblies.
