Abstract
Abstract A device or appliance comprising a light waveguide plug connector is composed of a pin seated resiliently and with play in a socket. Both the pin and socket have cylindrical portions and conical end portions, one of the pins and socket has an intermediate tapering portion with a taper substantially less than the taper of the conical end portion. The slightly tapered intermediate portion will facilitate the plugging in of the pin into the socket, even given a radial offset of the axis of the socket and the pin to each other.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
105 words
In a device containing at least one light waveguide plug connector, said plug connector having a pin-shaped part received in a socket-shaped part, said connector having at least one of the two parts being mounted on a wall member with radial movement relative to the wall member and means for axially biasing the two parts together, said two parts having cylindrical sections mated to one another during a plugging-in operation, the improvement comprising the socket-shaped part having an intermediate tapering section between a front conical section and the cylindrical section and the intermediate tapering section being provided with less taper than the front conical section.
Claim 2
Dependent Claim
105 words
In a device containing at least one light waveguide plug connector, said plug connector having a pin-shaped part received in a socket-shaped part, said connector having at least one of the two parts being mounted on a wall member with radial movement relative to the wall member and means for axially biasing the two parts together, said two parts having cylindrical sections mated to one another during a plugging-in operation, the improvement comprising the socket-shaped part having an intermediate tapering section between a front conical section and the cylindrical section and the intermediate tapering section being provided with less taper than the front conical section.
Claim 3
Dependent Claim
26 words
In a device acording to claim 1, wherein the intermediate section has a slant of less than 1° relative to an axis of the socket-shaped part.
Claim 4
Dependent Claim
31 words
In a device according to claim 1, wherein said parts are composed of a hard material selected from a group consisting of hard metal, ceramics and materials having similar material properties.
Claim 5
Dependent Claim
27 words
In a device according to claim 1, wherein at least one plug connector is arranged in a common mount together with at least one electrical plug connector.
Claim 6
Dependent Claim
70 words
In a device according to claim 1, wherein said one part extends through a bore in the wall member, said bore having a diameter greater than the outside diameter of said one part, said means for axially biasing the two parts together including a spring surrounding said one part and having one end acting on said wall member and another end acting on a shoulder provided on said one part.
Claim 7
Dependent Claim
26 words
In a device according to claim 5, wherein the intermediate tapering section has a slant of less than 1° to the axis of said socket-shaped part.
Claim 8
Dependent Claim
70 words
In a device according to claim 5, wherein said one part is received in a bore of a ring, which bore has a diameter less than the bore in the wall member, said ring being mounted in a recess on a surface of said wall member, said recess being greater than the diameter of said ring so that the ring can move in the recess relative to the wall member.
Claim 9
Dependent Claim
144 words
In a device according to claim 1, wherein said pin-shaped part is mounted in a wall member by means providing a radial play, said means for providing a radial play including a ring having a bore, said pin-shaped part extending through the bore of said ring with clearance, the wall member having an opening greater than the diameter of the bore of the ring, and having a recess surrounding the opening for receiving the ring, said recess having a diameter greater than the outer diameter of said ring so that the ring is movable relative to the wall member and the pin-shaped part is movable relative to the ring with the play between the wall member and pin-shaped part being proportioned with one-half of the play being between the pin-shaped part and ring and a second half being between the wall member and ring.
Claim 10
Dependent Claim
70 words
In a device according to claim 8, wherein the means for axially biasing includes a spring surrounding the pin-shaped part with one end acting on the ring and the other end acting on a first shoulder provided on said pin-shaped part, said pin-shaped part having a second shoulder spaced from the first shoulder to prevent said spring from pulling the pin-shaped part completely through the opening in said wall member.
Claim 11
Dependent Claim
123 words
In a device containing at least one light waveguide plug connector, said plug connector having a pin-shaped part received in a socket-shaped part, said connector having at least one of the two parts being mounted on a wall member with radial movement relative to the wall members and means for axially biasing the two parts together, said two parts having cylindrical sections mated to one another during a plugging-in operation, the improvement comprising said pin-shaped part having a front conical end section, said socket-shaped part having a front conical section, and only the socket-shaped part having an intermediate tapering section between said front conical section and the cylindrical section, said intermediate tapering section being provided with less taper than the front conical section.
Claim 12
Dependent Claim
123 words
In a device containing at least one light waveguide plug connector, said plug connector having a pin-shaped part received in a socket-shaped part, said connector having at least one of the two parts being mounted on a wall member with radial movement relative to the wall members and means for axially biasing the two parts together, said two parts having cylindrical sections mated to one another during a plugging-in operation, the improvement comprising said pin-shaped part having a front conical end section, said socket-shaped part having a front conical section, and only the socket-shaped part having an intermediate tapering section between said front conical section and the cylindrical section, said intermediate tapering section being provided with less taper than the front conical section.
Claim 13
Dependent Claim
26 words
In a device according to claim 10, wherein the intermeidate section has a slant of less than 1° relative to an axis of the socket-shaped part.
