Described optical fibre clip (300) is inserted in a tail sleeve (200), described tail sleeve (200) is connected on the rear end of described connector shell (100), thus is fixed on described connector shell (100) by described optical fibre clip (300).
The assemble method of 15. joints of optical fibre according to claim 14, it is characterised in that:
Described tail sleeve (200) and described optical fibre clip (300) are constructed such that described optical fibre clip (300) can be maintained separately first position and second position in described tail sleeve (200)；
When described optical fibre clip (300) is maintained at described first position, is there is bending by the pushing of described optical fibre clip (300) in the optical fiber (11) of described optical cable (10)；And
When described optical fibre clip (300) is maintained at described second position, the optical fiber (11) of described optical cable (10) is no longer influenced by the pushing of described optical fibre clip (300) and recovers straight.
The assemble method of 16. joints of optical fibre according to claim 15, it is characterised in that:
The described joints of optical fibre are by by the joints of optical fibre limited any one of claim 1-12.
The assemble method of 17. joints of optical fibre according to claim 16, it is characterised in that:
In described step S120, a pair flexure strip (310) of described optical fibre clip (300) bears against on a pair positioning convex (211) of described tail sleeve (200), in order to described optical fibre clip (300) is maintained at described first position.
The assemble method of 18. joints of optical fibre according to claim 17, further comprising the steps of:
S140: outwards pull described optical fibre clip (300), the flexure strip (310) on described optical fibre clip (300) is made to slip over positioning convex (211), and engage with the retention tab (220) in described tail sleeve (200), thus described optical fibre clip (300) is maintained at described second position.
The method for dismounting of 19. 1 kinds of joints of optical fibre, the described joints of optical fibre are limited by claim 8, and described method for dismounting comprises the following steps:
S210: release described optical cable and optical fibres (11) and the locking of pre-buried optical fiber (111)；
S220: press inward against the lobe (210a) of a pair elastic arm (210), a pair elastic arm (210) is squeezed on a pair flexure strip (310) of optical fibre clip (300) respectively, in order to release the joint between flexure strip (310) and retention tab (220)；With
S230: outwards pull described optical fibre clip (300) so that described optical fibre clip (300) is extracted from described tail sleeve (200).
