Abstract

According to the present invention, there is provided a connector for attachment to the end of an optical fibre; the connector comprising a rear body and a resilient biasing member; wherein the rear body comprises a longitudinal slot configured to allow a cable to be inserted; wherein the rear body comprises a transverse slot configured to receive the resilient biasing member, wherein the resilient biasing member has a shape configured to allow a cable to be inserted the longitudinal slot. A kit of parts comprising the connector is also described.

Claims (23)

1 . A connector for attachment to the end of an optical fiber, comprising:

a rear body and a resilient biasing member in the form of a resilient biasing clip comprising two deflectable tines,

wherein the rear body comprises a longitudinal slot configured to allow a cable to be inserted,

wherein the rear body comprises a transverse slot configured to receive the resilient biasing clip,

wherein the resilient biasing member has a shape configured to allow a cable to be inserted the longitudinal slot,

wherein the transverse slot of the rear body has a cross section formed of a first rectangle and second rectangle, and

wherein the first rectangle has a greater length than the second rectangle, and the first and second rectangles both have lengths greater than a diameter of the longitudinal slot.

2 . The connector of claim 1 , wherein the diameter of the longitudinal slot is in the range of 0.90 to 2.00 mm.

3 . The connector of claim 1 , wherein the resilient biasing clip is substantially U-shaped.

4 . The connector of claim 1 , wherein the resilient biasing clip has a thickness in the range of 0.1 to 0.7 mm.

5 . The connector of claim 1 , wherein the resilient biasing member comprises stainless steel.

6 . The connector of claim 1 , wherein the resilient biasing member comprises beryllium copper.

7 . The connector of claim 1 , wherein the resilient biasing member is integrally formed in one piece.

8 . The connector of claim 1 , wherein the connector further comprises a ferrule holder, the ferrule holder having an internal bore.

9 . The connector of claim 8 , wherein the connector does not comprise a spring extending from the ferrule holder.

10 . The connector of claim 8 , wherein the ferrule holder comprises an internal bore and wherein the internal bore has a tapered end.

11 . The connector of claim 10 , wherein the tapered end of the internal bore of the ferrule holder is curved.

12 . The connector of claim 11 , wherein the tapered end of the internal bore of the ferrule holder is tapered in a concave curve.

13 . A kit, comprising:

the connector of claim 1 ;

a fibre optic blowing accessory; and

an installation tube,

wherein the fibre optic blowing accessory has an outer diameter between 75% and 85% of an inner diameter of the installation tube.
