Embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe embodiment of the present utility model in detail.

Such as Fig. 1-shown in Figure 5, the joints of optical fibre of the present utility model comprise ceramic insertion core 1, tailstock 2, front baffle ring 8, rear baffle ring 3, inside casing cover 11 and tail frame 7.

Wherein, be provided with shoulder hole in tailstock 2, front baffle ring 8 and the rear baffle ring 3, tailstock 2, front baffle ring 8 and rear baffle ring 3 are sleeved on the outside of ceramic insertion core 1 successively.Inside casing cover 11 and tail frame 7 are sleeved on rear baffle ring 3 outsides, and inside casing cover 11 and tail frame 7 are set up in parallel.Rear baffle ring 3 is provided with the first limited block 13 and the second limited block 14, inside casing cover 11 is provided with the first spacing window 15 that cooperates with the first limited block 13, tail frame 7 is provided with the second spacing window 16 that cooperates with the second limited block 14, the first limited block 13 is positioned at the first spacing window 15, the second limited blocks 14 and is positioned at the second spacing window 16.Can limit the amplitude of stretching out and inside contracting of ceramic insertion core 1 by the first limited block 13, the second limited block 14, the first spacing window 15 and the second spacing window 16.Be provided with cushion space in the second spacing window 16, when ceramic insertion core 1 is subject to bump when inside contracting, impact is transmitted successively by tailstock 2, front baffle ring 8 and rear baffle ring 3, rear baffle ring 3 contacts with tail frame 7, promoting tail frame 7 moves, tail frame 7 can and inside casing cover 11 break away from, the second spacing window 16 on the tail frame 7 is also thereupon mobile, such as Fig. 6-shown in Figure 9.Because the first spacing window 15 on the inside casing cover 11 can limit the first limited block 13, so tail frame 7 is when moving, and rear baffle ring 3 can not move.Owing to be provided with cushion space in the second spacing window 16, the second spacing window 16 just can contact with the second limited block 14 after moving a segment distance with tail frame 7, tail frame 7 just can stop to move after the second spacing window 16 contacted with the second limited block 14, so cushion space has played the effect of buffering.The impact that ceramic insertion core 1 is subject to has been transferred on the tail frame 7, is used for promoting tail frame 7 and moves, and therefore can effectively avoid the lock pin damage.
