Separable fiber optic cable connector

Claim 2

A separable fiber optic connector comprising: male and female halves each having a central bore extending therethrough; a resilient collar member concentrically secured within said bore portions said collar having at least one longitudinal opening extending therethrough; a rigid sleeve member slidably mounted into said collar opening; each end of said sleeve member adapted to receive the terminal end of a pair of respective fiber optic cables to be optically aligned together; said resilient collar member enabling the rigid sleeve member to be longitudinally displaced from the respective collar opening from either side thereof; and means for maintaining said members in longitudinal relation within the connector.

Claim 3

The connector of claim 1 wherein said sleeve member is resiliently engaged by the collar member.

Claim 4

The connector of claim 1 wherein said sleeve member has a smooth unobstructed central bore portion to receive said fiber optic cable terminal ends, and means are provided for maintaining said cable ends in a closely spaced, single air-to-glass optical junction within the sleeve member.

Claim 5

The connector of claim 3 wherein detent means are provided for detachably anchoring said sleeve member within the collar member.

Claim 6

The connector of claim 3 wherein the longitudinal bore and outer surfaces of said resilient collar member is provided with one or more spaced ribs.

Claim 7

The connector of claim 3 wherein said cable ends are each anchored in a terminal for positioning said cable ends within the respective sleeve member the ends of said sleeve and terminals having respective shoulders for limiting the inward position of the respective terminals to maintain said said spaced optical junction; and an annular gasket positioned between each pair of said shoulders.

Claim 8

The connector of claim 3 wherein said optically spaced junction is in the order of 0.001" to 0.006".

Claim 9

The connector of claim 2 wherein said sleeve member is longer than the length of the collar and projects beyond both ends thereover.

Claim 10

A separable multi-port fiber optic connector for joining a plurality of glass fiber optic cables comprising: male and female halves each having a bore portion; a collar member made of a single piece of compressible material concentrically positioned within the said bore portions; said collar member having a plurality of circumferentially spaced longitudinal openings extending therethrough; a rigid sleeve member resiliently secured in each opening and being of a length greater than the length of the collar member and projecting beyond each end of the ferrule member; each sleeve member having a smooth uninterrupted central bore portion for receiving in each end one terminal end of a pair of respective fiber optic cables; means for limiting the inward positioning of each of said terminal ends within its respective sleeve end so as to maintain said cable ends in a closely spaced single air-to-glass optical junction; said collar member enabling said sleeve members to be individually displaced longitudinally from either side thereof.

Claim 11

A separable multi-port fiber optic connector for joining a plurality of glass fiber optic cables comprising: male and female halves each having a bore portion; a collar member made of a single piece of compressible material concentrically positioned within the said bore portions; said collar member having a plurality of circumferentially spaced longitudinal openings extending therethrough; a rigid sleeve member resiliently secured in each opening and being of a length greater than the length of the collar member and projecting beyond each end of the ferrule member; each sleeve member having a smooth uninterrupted central bore portion for receiving in each end one terminal end of a pair of respective fiber optic cables; means for limiting the inward positioning of each of said terminal ends within its respective sleeve end so as to maintain said cable ends in a closely spaced single air-to-glass optical junction; said collar member enabling said sleeve members to be individually displaced longitudinally from either side thereof.

Claim 12

The connector of claim 1 wherein detent means are provided between the circumferential surface of openings in the collar and the outer surface of the respective sleeve members.

Claim 13

The connector of claim 9 wherein each of said connector halves is provided with a rigid cylindrical plug member having a plurality of longitudinal openings each capable of receiving and supporting a respective projecting end of the sleeve members.

Claim 14

The connector of claim 9 wherein the bore of each end of said sleeve members is provided with an internal recessed shoulder adapted to be abutted by a shoulder on the respective cable terminals for limiting the inward position of the cable ends within the sleeve member; and sealing means positioned between said shoulders.

Claim 15

A separable fiber optical connector body member having an unrestricted bore opening extending therethrough; a pair of terminals having inner ends coextensive with the ends of respective fiber optical cables secured therein for extending into the bore opening to be optically connected together; said bore opening having an internal shoulder at each end adapted to be abutted by a shoulder on a respective terminal for limiting the inward position of the cable ends within the body member to be in close but spaced relationship in the order of 0.001" to 0.006" to provide a single air-to-glass optical junction between said cable ends within the body member; annular sealing means positioned between each pair of shoulders; and means for securing said terminals within the connector and compressing the sealing means.

Claim 16

A separable fiber optical connector body member having an unrestricted bore opening extending therethrough; a pair of terminals having inner ends coextensive with the ends of respective fiber optical cables secured therein for extending into the bore opening to be optically connected together; said bore opening having an internal shoulder at each end adapted to be abutted by a shoulder on a respective terminal for limiting the inward position of the cable ends within the body member to be in close but spaced relationship in the order of 0.001" to 0.006" to provide a single air-to-glass optical junction between said cable ends within the body member; annular sealing means positioned between each pair of shoulders; and means for securing said terminals within the connector and compressing the sealing means.

Claim 17

The separable fiber optic connector of claim 2 wherein said rigid sleeve member has transverse symmetry.
