Fiber optic cable end connector

Claim 2

An end connector for connecting a fiber optic cable to a port associated with a piece of equipment, said cable having at least one optic fiber and at least one other support member surrounded by a jacket, said end connector comprising: a housing member having a front end and a rear end, said housing member defining a passageway extending from said rear end to said front end for passing said cable therethrough; coupling means for coupling said housing member to said port; clamp means received in said passageway and adapted to at least partially surround said cable, said clamp means being adjustable between an expanded state which accommodates movement of said cable with respect to said housing and a constricted state which fixedly secures said cable with respect to said housing, said clamp means being adapted to receive an insert, said insert including means for axially supporting said insert within said clamp means while engaging said cable jacket; and clamp adjustment means for adjusting said clamp means between said expanded and said constricted states.

Claim 3

The end connector as claimed in claim 1, wherein said clamp means comprises a resilient split sleeve.

Claim 4

The end connector as claimed in claim 2, wherein said split sleeve is adjusted between said expanded state and said constricted state by being axially displaced within said passageway.

Claim 5

The end connector as claimed in claim 3, wherein said clamp adjustment means comprises a clamp engagement member releasably coupled within said passageway at said rear end of said housing member, said clamp engagement member axially displacing said split sleeve within said passageway.

Claim 6

The end connector as claimed in claim 4, further comprising: a sealing grommet disposed within a recess disposed in said clamp engagement member and adapted to substantially surround a portion of said cable; and a sealing member releasably coupled within said clamp engagement member, said sealing member being arranged to contact said sealing grommet and to force said sealing grommet to deform within said recess so as to provide a tight seal around said portion of said cable.

Claim 7

The end connector as claimed in claim 5, further comprising a conductive seal disposed within said passageway adjacent said split sleeve, said conductive seal being deformed so as to come into close contact with a conductive shield member associated with said cable as said split sleeve is axially displaced to said constricted state, said conductive seal effectively grounding said shield member in order to prevent spurious signals from penetrating said cable.

Claim 8

The end connector as claimed in claim 6, further comprising a high voltage surge grounding member disposed between said split sleeve and said conductive seal and which is arranged to contact said conductive shield member as said split sleeve is displaced to said second position for grounding high voltage surges applied to said cable.

Claim 9

The end connector of claim 1, wherein said insert comprises a plurality of radially inward facing protuberances for engaging said cable jacket.

Claim 10

An end connector for connecting a fiber optic cable to a port associated with a piece of equipment, said cable having at least one optic fiber surrounded by a jacket, said end connector comprising: a housing member having a front end and a rear end, said housing member defining a passageway extending from said rear end to said front end for passing said cable therethrough; coupling means for coupling said housing member to said port; a cable clamp received in said passageway and adapted to at least partially surround said cable, said cable clamp being displaceable along said passageway between a first position which allows movement of said cable with respect to said housing and a second position which applies a clamping pressure to said cable so as to fixedly secure said cable within said housing, said cable clamp being adapted to receive an insert, said insert including means for axially supporting said insert within said cable clamp while engaging said cable jacket; and a clamp engagement member releasably coupled within said passageway at said rear end of said housing member, said clamp engagement member being arranged to contact said cable clamp and to urge said cable clamp to displace to said second position.

Claim 11

An end connector for connecting a fiber optic cable to a port associated with a piece of equipment, said cable having at least one optic fiber surrounded by a jacket, said end connector comprising: a housing member having a front end and a rear end, said housing member defining a passageway extending from said rear end to said front end for passing said cable therethrough; coupling means for coupling said housing member to said port; a cable clamp received in said passageway and adapted to at least partially surround said cable, said cable clamp being displaceable along said passageway between a first position which allows movement of said cable with respect to said housing and a second position which applies a clamping pressure to said cable so as to fixedly secure said cable within said housing, said cable clamp being adapted to receive an insert, said insert including means for axially supporting said insert within said cable clamp while engaging said cable jacket; and a clamp engagement member releasably coupled within said passageway at said rear end of said housing member, said clamp engagement member being arranged to contact said cable clamp and to urge said cable clamp to displace to said second position.

Claim 12

The end connector as claimed in claim 9, wherein said cable clamp comprises a resilient split sleeve.

Claim 13

The end connector as claimed in claim 10, wherein said sleeve has an inner surface and an outer surface, said sleeve being adapted to compress and expand in order to provide an increase and decrease, respectively, of clamping pressure on said cable.

Claim 14

The end connector as claimed in claim 11, wherein sad cable clamp further comprises at least one protruding member provided on said outer surface of said sleeve, which abuts a surface portion of said housing member within said passageway, said at least one protruding member forcing said sleeve to compress as said cable clamp is displaced to said second position.

Claim 15

The end connector as claimed in claim 12, wherein said at least one protruding member is ramp shaped.

Claim 16

The end connector as claimed in claim 12, wherein sad at least one protruding member has a knurled surface so as to resist rotational forces when in contact with said surface portion of said housing member.

Claim 17

The end connector as claimed in claim 9, wherein said insert comprises a plurality of radially inward facing protuberances for engaging said cable jacket.
