Embodiment 1

[0047] The implementation principle of Embodiment 1 is as follows: the exposed end of the cable 10 is sealed by setting the waterproof cover 2, so as to effectively prevent the intrusion of external water; In order to reduce the probability of the waterproof case 2 detaching, and the closed end of the waterproof case 2 is locked by the beam sleeve 13, so as to improve the waterproof effect.

Embodiment 2

[0048] Embodiment 2 is different from Embodiment 1 in that, as image 3 As shown, the waterproof cover 2 is an elastic telescopic cover, which is made of rubber. When the cable 10 is placed in the steel wire rope net 11 and the steel wire rope net 11 is pre-tightened (at this time, the distance between the traction rope 12 and the end of the steel wire rope net 11 is pulled. Large), and then unfold the waterproof cover 2, so that the open end of the waterproof cover 2 extends to the position corresponding to the end of the cable 10 on the wire rope net 11, thereby realizing the sealing of the end of the cable 10, and its operation is convenient and quick.

[0049] Moreover, in order to further improve the sealing effect of the opening end of the waterproof sheath 2 on the end of the cable 10, after the waterproof sheath 2 is extended, a clamping member 3 can be sleeved on the outer wall of the opening end of the waterproof sheath 2, and the clamping member 3 can be a clamp , s...

Embodiment 3

[0050] Embodiment 3 is different from Embodiment 1 in that, as Figure 4 As shown, the waterproof cover 2 can be made of elastic material, or hard plastic or metal material. The waterproof cover 2 in this embodiment is made of rubber material, and the waterproof cover 2 is located in the tapered accommodation cavity formed by the multi-strand connecting rope 14. Inside.

[0051] First, elastically wrap the opening end of the waterproof cover 2 on the outer wall of the end of the cable 10, then put the waterproof cover 2 and the cable 10 into the steel wire rope net 11 at the same time, at this time, the waterproof cover 2 is located in the accommodation cavity, and then pre-tighten the steel wire rope Net 11, steel wire rope net 11 is tightened and fixed to the outer wall of waterproof case 2.

[0052] By putting the waterproof case 2 into the accommodation cavity, firstly, the waterproof case 2 is protected through the connecting rope 14 and the steel wire netting 11, so as ...

Abstract

The invention relates to a net pulling sleeve for an optical fiber cable, which comprises a steel wire rope net and a waterproof sleeve. A pulling rope is integrally formed at one end of the steel wire rope net. One end of the waterproof sleeve is a closed end, the other end of the waterproof sleeve is an open end, and the open end of the waterproof sleeve is used for sleeving the end of a cable or sleeving the outer wall of the steel wire rope net. According to the application, the waterproof sleeve is arranged to seal the exposed end of the cable so as to effectively prevent external water from invading.

Description

technical field [0001] The application relates to a mesh pull sleeve for optical fiber cables. Background technique [0002] Net pull sleeve, also known as cable net sleeve connector, wire net sleeve, pull wire net sleeve, optical cable net sleeve, is a simple device used for connecting cables and optical cables during construction. [0003] The existing net pull sleeve includes a wire rope net, a traction rope and a beam mouth sleeve, wherein the steel rope net is used to cover a fixed cable, and one end of the traction rope is integrally connected with the steel wire net, and the traction rope is used to connect with the traction equipment, so as to pass through the steel rope net. The cable is pulled. [0004] In view of the related technologies mentioned above, the inventor believes that when used in rainy days or in an environment with large water accumulation, water will easily enter the cable from the end of the cable through the net pull sleeve, which will easily ca...
