Detailed Description
The invention is further described below with reference to the accompanying drawings and the detailed description.
Referring to fig. 1 to 2, a protection device after fusion splicing of a follow-up cable optical fiber is shown, which includes a supporting plate 100, and two sliding grooves 111 are formed on one surface of the supporting plate 100, for example, on an upper surface 110 of the supporting plate 100 shown in fig. 1 and 2, and spaced apart from each other in a direction perpendicular to a stretching direction of a telescopic cable clamp.
The utility model provides a concertina type cable clamp be two pairs, certainly do not confine to two pairs yet, a pair of also can, three pairs and above also can.
The straight sections 211, 221 of the two telescoping cable clamps 210, 220 of each pair of telescoping cable clamps are slidably disposed within the chute 111. Referring to fig. 1, encountering a wider width of the trailing cable 300 (see fig. 3), the two telescoping cable clamps 210, 220 are pulled outwardly. When the following cable 300 with a narrow width is encountered, the two telescopic cable clamps 210 and 220 are pushed inwards, so that the width between the two telescopic cable clamps 210 and 220 is suitable for the width of the following cable 300.
The two telescopic cable clamps 210 and 220 each have an upwardly and inwardly turned clamping end 212 and 222, and a band fixing buckle 213 and 223 is disposed on the clamping end 212 and 222 of each telescopic cable clamp 210 and 220.
