Fiber optic end connector

Claim 2

A connector for connecting a tubular support structure associated with a fiber optic cable to a terminal of a signal processing device, said tubular support structure enclosing at least one optic fiber, said connector comprising: a housing member having a front end and a rear end, said housing member defining a first passageway extending from said rear end to said front end for axially passing said tubular support structure therethrough; coupling means threadedly engageable with the front end of said housing for coupling said housing member to said terminal; flexible clamp means at least partially received within said first passageway at said front end and adapted to at least partially surround said tubular support structure; clamp adjustment means threadedly engageable with said rear end; and compression means responsive to threaded engagement of said clamp adjustment means with the rear end of said housing for radially inwardly urging said clamp means from an expanded state accommodating axial passage of said tubular support structure through said housing into a constricted state fixedly securing said tubular support structure with respect to said housing.

Claim 3

The connector as claimed in claim 1, wherein said clamp adjustment means defines a second passageway for passing said tubular support structure therethrough, said clamp means at least partially received within said second passageway.

Claim 4

The connector as claimed in claim 2, wherein said clamp adjustment means is arranged to contact said clamp means in order to adjust said clamp means between said expanded and constricted states.

Claim 5

The connector as claimed in claim 1, wherein said clamp means comprises a flexible sleeve at least partially surrounding said tubular support structure and adapted to constrict inwardly about said tubular support structure in order to provide increasing clamping pressure on said tubular support structure as said clamp means is adjusted to said constricted state.

Claim 6

The connector as claimed in claim 4, wherein said compression means comprises a grommet at least partially surrounding said flexible sleeve and adapted to compress inwardly about said flexible sleeve which in turn provides increasing clamping pressure on said tubular support structure as said clamp means is adjusted to said constricted state.

Claim 7

The connector as claimed in claim 5, wherein said clamp adjustment means defines a second passageway for passing said tubular support structure therethrough, said clamp means at least partially received within said second passageway.

Claim 8

The connector as claimed in claim 6, wherein said clamp adjustment means is arranged to contact said clamp means in order to adjust said clamp means between said expanded and constricted states.

Claim 9

The connector as claimed in claim 7, wherein said first passageway defines a first recess which receives front end portions of said flexible sleeve and said grommet, said second passageway defining a second passageway which receives rear end portions of said flexible sleeve and said grommet.

Claim 10

The connector as claimed in claim 8, wherein said first and second recesses include compression surfaces which contact said grommet so as to compress said grommet as said clamp adjustment means is coupled to said rear end of said housing.

Claim 11

An end connector for connecting a tubular support structure associated with a fiber optic cable to a terminal of a signal processing device, said tubular support structure enclosing at least one optic fiber, said end connector comprising: a housing member having a front end and a rear end, said housing member defining a first passageway extending from said rear end to said front end for passing said tubular support structure therethrough, said front end adapted to be coupled to said terminal; a first clamp member adapted to at least partially surround said tubular support structure, said first clamp member being adjustable between an expanded state which accommodates movement of said tubular support structure with respect to said housing and a constricted state which fixedly secures said tubular support structure with respect to said housing; a second clamp member adapted to at least partially surround said first clamp member, said second clamp member operable for adjusting said first clamp member between said expanded and constricted states; and a clamp adjustment member releasably coupled to said rear end of said housing member and arranged to coact with said second clamp member in order to adjust said first clamp means between said expanded and constricted states.

Claim 12

An end connector for connecting a tubular support structure associated with a fiber optic cable to a terminal of a signal processing device, said tubular support structure enclosing at least one optic fiber, said end connector comprising: a housing member having a front end and a rear end, said housing member defining a first passageway extending from said rear end to said front end for passing said tubular support structure therethrough, said front end adapted to be coupled to said terminal; a first clamp member adapted to at least partially surround said tubular support structure, said first clamp member being adjustable between an expanded state which accommodates movement of said tubular support structure with respect to said housing and a constricted state which fixedly secures said tubular support structure with respect to said housing; a second clamp member adapted to at least partially surround said first clamp member, said second clamp member operable for adjusting said first clamp member between said expanded and constricted states; and a clamp adjustment member releasably coupled to said rear end of said housing member and arranged to coact with said second clamp member in order to adjust said first clamp means between said expanded and constricted states.

Claim 13

The end connector as claimed in claim 10, wherein said first clamp member comprises a flexible sleeve at least partially surrounding said tubular support structure, and is adapted to constrict inwardly about said tubular support structure in order to provide increasing clamping pressure on said tubular support structure as it is adjusted to said constricted state.

Claim 14

The end connector as claimed in claim 11, wherein said second clamp member comprises a grommet which is adapted to compress inwardly about said flexible sleeve which in turn provides increasing clamping pressure on said tubular support structure as said clamp adjustment member is coupled to said housing member.

Claim 15

The end connector as claimed in claim 12, wherein said clamp adjustment member defines a second passageway for passing said tubular support structure therethrough, said first and second clamp members at least partially received within said second passageway.

Claim 16

The end connector as claimed in claim 13, wherein said first passageway defines a first recess which receives front end portions of said flexible sleeve and said grommet, said second passageway defining a second passageway which receives rear end portions of said flexible sleeve and said grommet.

Claim 17

The end connector as claimed in claim 14, wherein said first and second recesses include compression surfaces which contact said grommet so as to compress said grommet as said clamp adjustment member is coupled to said rear end of said housing.

Claim 18

The end connector as claimed in claim 15, wherein said clamp adjustment member is coupled to said rear end of said housing by threaded engagement.
