Optical fiber terminals with V-groove alignment

Claim 2

In a connector for coupling a pair of optical fibers, a body defining a channel for receiving the endwise insertion of said fibers in opposed end-to-end relationship and means for holding the inserted fiber ends in the body channel, said means occupying part of said channel in the path of said endwise insertion, said means being in contact with a substantial axial length of the fiber end portions, in register with a wall of the channel and resiliently displaceable in a lateral direction by said insertion whereby upon insertion of said fiber ends into said channel said means urges said fiber end portions laterally against the wall of the channel and holds the fibers in the body in coupled relationship.

Claim 3

The invention as defined in claim 1 wherein said holding means urges the end portions of the fibers against a bottom wall of said channel, said bottom wall being V-shaped in cross-section.

Claim 4

The invention as defined in claim 2 wherein said body is elongated and said channel extends from one end to the other end.

Claim 5

The invention as defined in claim 3 wherein at least one end of said body defines a tapered opening in alignment with said channel.

Claim 6

The invention as defined in claim 1 wherein said holding means comprises a resilient axially extending wire.

Claim 7

The invention as defined in claim 5 wherein said wire urges the fibers against the bottom wall of said channel, said bottom wall being V-shaped in cross-section.

Claim 8

The invention as defined in claim 6 wherein said body is elongated and said channel extends from one end to the other end.

Claim 9

The invention as defined in claim 7 wherein said wire is disposed in said channel and extends axially thereof opposite said bottom wall, the ends of said wire being supported by said body.

Claim 10

The invention as defined in claim 8 wherein said channel has spaced parallel side walls extending from said V-shaped bottom wall and has a top wall opposite said bottom wall for supporting the end of said wire.

Claim 11

The invention as defined in claim 9 wherein said body is cylindrical and wherein said top wall defines a recess, said wire having one end disposed in said recess.

Claim 12

The invention as defined in claim 10 wherein said body is a unitary molded plastic body.

Claim 13

The invention as defined in claim 8 wherein said wire has an axially extending central section and opposite end sections extending from the central section away from said V-shaped bottom wall of the channel, the junctures of each oblique section with said central section being of arcuate configuration whereby said wire is resiliently displaced by a camming action upon insertion of a fiber.

Claim 14

A mateable pair of terminals for coupling optical fibers comprising: a pin having an axial channel extending from a rearward end to a forward end of the pin for receiving the end wise insertion of said fibers, means for securing an optical fiber to the rearward end of the pin with the fiber extending partially through the channel, said channel being adapted to receive another optical fiber removably extending into the forward end of the pin, a socket having a forward end adapted to receive said pin in telescopic relation, means for securing another optical fiber to the rearward end of the socket with the free end of the fiber extending partially through said socket, whereby said free end enters said channel at the forward end of the pin when the pin is matingly engaged with the socket, and means for holding a substantial axial length of the end portions of the two fiber ends in opposed end-to-end relationship, said holding means occupying part of said channel in the path of said end wise insertion of said fibers and being in contact with and resiliently displaceable in a lateral direction by said fiber insertion whereby said holding means urges the axial length of the two fiber end portions laterally into alignment with each other and against the channel.

Claim 15

A mateable pair of terminals for coupling optical fibers comprising: a pin having an axial channel extending from a rearward end to a forward end of the pin for receiving the end wise insertion of said fibers, means for securing an optical fiber to the rearward end of the pin with the fiber extending partially through the channel, said channel being adapted to receive another optical fiber removably extending into the forward end of the pin, a socket having a forward end adapted to receive said pin in telescopic relation, means for securing another optical fiber to the rearward end of the socket with the free end of the fiber extending partially through said socket, whereby said free end enters said channel at the forward end of the pin when the pin is matingly engaged with the socket, and means for holding a substantial axial length of the end portions of the two fiber ends in opposed end-to-end relationship, said holding means occupying part of said channel in the path of said end wise insertion of said fibers and being in contact with and resiliently displaceable in a lateral direction by said fiber insertion whereby said holding means urges the axial length of the two fiber end portions laterally into alignment with each other and against the channel.

Claim 16

The invention as defined in claim 13 wherein said holding means urges said fibers against a bottom wall of said channel, said bottom wall being V-shaped in cross-section.

Claim 17

The invention as defined in claim 14 wherein said holding means comprises a resilient axially elongated wire.

Claim 18

The invention as defined in claim 15 wherein said wire is disposed in said channel and extends axially thereof opposite said bottom wall.

Claim 19

The invention as defined in claim 16 wherein said channel has spaced parallel side walls extending from said V-shaped bottom wall and has a top wall opposite said bottom wall for supporting the ends of said wire.

Claim 20

The invention as defined in claim 17 wherein said wire has an axially extending central section and opposite end sections extending from the central section obliquely away from said V-shaped bottom wall of the channel, the junctures of each oblique section with said central section being of arcuate configuration whereby said wire is resiliently displaced by a camming action upon insertion of a fiber.
