Abstract
Abstract The connector comprises means (2) defining a bore (4) to receive a bared end portion or portions (20) of an optical fibre cable (16), the means (2) being surrounded by a body (12) of sealant material and a member (10) of heat recoverable material. After insertion of the cable or cables, (16) the member (12) is recovered and compresses the sealant material (10) into intimate contact with the means (2) and cable or cables (16).

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
117 words
An optical fibre connector comprising means (2; 37) defining a bore (4; 38) to receive a bared end portion (20; 110) of an optical fibre cable; a body (12; 32) of sealant material adapted and arranged to guide an optical fibre into said bore; (4; 38) and a member (10; 31) of heat-recoverable material enclosing the body (12; 32) of sealant material, the arrangement being such that after insertion of a bared end portion (20; 110) of an optical fibre into said bore (4; 38) the member (10; 31) of heat-recoverable material is recovered and compresses the body (12; 32) of sealant material into intimate contact with the optical fibre cable and said bore-defining means (2; 37).
Claim 2
Dependent Claim
117 words
An optical fibre connector comprising means (2; 37) defining a bore (4; 38) to receive a bared end portion (20; 110) of an optical fibre cable; a body (12; 32) of sealant material adapted and arranged to guide an optical fibre into said bore; (4; 38) and a member (10; 31) of heat-recoverable material enclosing the body (12; 32) of sealant material, the arrangement being such that after insertion of a bared end portion (20; 110) of an optical fibre into said bore (4; 38) the member (10; 31) of heat-recoverable material is recovered and compresses the body (12; 32) of sealant material into intimate contact with the optical fibre cable and said bore-defining means (2; 37).
Claim 3
Dependent Claim
36 words
A connector as claimed in Claim 1, in which the body (12; 32) of sealant material has a hole with an inwardly tapering-end portion which serves to guide the optical fibre into said bore (4; 38).
Claim 4
Dependent Claim
22 words
A connector as claimed in Claim 1 or Claim 2, in which the member (10; 31) of heat recoverable material is tubular.
Claim 5
Dependent Claim
100 words
A connector as claimed in any preceding claim, including a rigid tubular member (34) about which the body (32) of sealant material is formed, said bore (38) being substantially on the axis of the rigid tubular member, and the rigid tubular member being formed with a plurality of through holes (35) through which the sealant material can pass, the arrangement being such that on recovery of the member (31) of heat-recoverable material sealant material initially between the member (31) of heat-recoverable material and the rigid tubular member (34) is urged through the holes (35) in the rigid tubular member (34).
Claim 6
Dependent Claim
25 words
A connector as claimed in Claim 4, in which the rigid tubular member (34) extends beyond both ends of the body (32) of sealant material.
Claim 7
Dependent Claim
25 words
A connector as claimed in Claim 5, in which the rigid tubular member (34) extends beyond both ends of the member (31) of heat-recoverable material.
Claim 8
Dependent Claim
38 words
A connector as claimed in Claim 5 or Claim 6, in which those portions of the rigid tubular member (34) which extend beyond the ends of the body (33) of sealant material are not formed with through holes.
Claim 9
Dependent Claim
56 words
A connector as claimed in any one of Claims 5 to 7, in which the bore-defining means (37) is located in the portion (36) of the rigid tubular member (34) which extends beyond the end of the body (32) of sealant material opposite to the end of insertion of the optical fibre into said bore (38).
Claim 10
Dependent Claim
54 words
A connector as claimed in any one of Claims 5 to 8, including a lens member (39) located in the portion (36) of the rigid tubular member (34) which extends beyond the end of the body (32) of sealant material opposite to the end of insertion of the optical fibre into said bore (37).
Claim 11
Dependent Claim
27 words
A connector as claimed in any preceding claim, adapted to receive an optical fibre cable from each of two opposite ends thereby to provide a splice connection.
Claim 12
Dependent Claim
31 words
A connector as claimed in any preceding claim, in which the body (32) of sealant material is softenable by heat applied to effect recovery of the member (21) of heat-recoverable material.
