The advantages are that: the utility model discloses can let the tail optical fiber be difficult for being pulled out by external force, let the use more stable.

Description

Anti-pulling plug

Technical Field

The utility model belongs to the technical field of the end cap, especially, relate to an anti-pulling end cap.

Background

At present, the joint part of the tail fiber needs to be plugged through a plug after installation so as to avoid the influence of external adverse factors (such as water vapor, dust and the like) on the use of the joint; however, the existing plug has no anti-pulling performance, so the head of the tail fiber is easily pulled out under the action of external force, which affects the normal use of the tail fiber; there is a need for improvement.

Disclosure of Invention

The utility model aims at providing a to the not enough of above-mentioned prior art existence, provide one kind and prevent drawing the end cap, it has and can let the tail optical fiber be difficult for being pulled out by external force, lets use more stable characteristics.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: an anti-pulling plug comprises a joint, wherein a wire passing channel is formed in the joint; the tail end joint that connects has prevents drawing the sleeve pipe, prevent drawing sheathed tube structure and be: the pipe fitting comprises a left half pipe and a right half pipe, wherein the left half pipe and the right half pipe are hinged with each other, a positioning hole is formed in the left half pipe, an inserting column is arranged on the right half pipe, and the inserting column and the positioning hole are inserted and positioned in use; the left half pipe and the right half pipe are respectively provided with a latch, and a pulling-proof interval for clamping the cable is formed between the upper and lower opposite latches.

The inserting column is of a cylindrical structure with a wide lower part and a narrow upper part, and the positioning hole is a cylindrical blind hole with a narrow lower part and a wide upper part.

The left half pipe is hinged to the right half pipe through a flexible belt, and the flexible belt is made of plastic materials.

After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses a relative latch forms prevents drawing the interval, prevents drawing the interval and can carry the crust line of tail optical fiber cable portion, avoids the tail optical fiber to deviate from its head when receiving external force and dragging, improves the stability of using.

Detailed Description

The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, and the present invention will be further explained with reference to the drawings and the embodiments.

Example, see figure 1: an anti-pulling plug comprises a connector 10, wherein a wire passing channel 11 is formed in the connector 10, the wire passing channel 11 penetrates through two end faces of the connector 10, and the cross section of the wire passing channel is the same as the head of a tail fiber. The tail end of the connector 10 is clamped with a pull-proof sleeve 20, and the structure of the pull-proof sleeve 20 is as follows: including left half pipe 21 and right half pipe 22, hinge through flexible band 26 between left half pipe 21 and the right half pipe 22, and the three all adopts the plastic material to make to integrated into one piece. The left half pipe 21 is provided with the positioning hole 23, the right half pipe 22 is provided with the inserting column 24, the number of the inserting column 24 is the same as that of the positioning hole 23, generally, the number of the inserting column 24 is two, and the inserting column 24 and the positioning hole 23 are inserted and positioned in use, so that the left half pipe 21 and the right half pipe 22 can be effectively prevented from moving after being inserted and positioned, and meanwhile, the installation is convenient. The inserting column 24 is a cylindrical structure with a wide lower part and a narrow upper part, the positioning hole 23 is a cylindrical blind hole with a narrow lower part and a wide upper part, the inserting connection is interference fit, the inserting connection of the inserting column 24 and the positioning hole 23 is convenient due to the structural fit, and the inserting column is not easy to separate after the inserting connection. The left half pipe 21 and the right half pipe 22 are both provided with clamping teeth 25, and an anti-pulling interval for clamping the cable is formed between the upper and lower opposite clamping teeth 25; in use, the cable part of the tail fiber passes through the pulling-proof interval and clamps the sheath wire thereof through the latch 25, so that the head of the tail fiber can be prevented from being separated when the tail fiber is pulled by external force, and the use stability is improved.
