Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to an anti-interference cable. Background Art

[0002] Cables are usually rope-like cables made up of several or several groups of wires twisted together. Each group of wires is insulated from each other, and after the wires are aggregated, one or more layers of protective sheath are wrapped around the outer surface to prevent leakage of the cable during use and thus cause accidents.

[0003] According to a disclosed anti-interference cable (publication number: CN220041425U), in the above application, the cable cores can be supported and reinforced by a support frame arranged in the middle of multiple cable cores, so that the anti-interference cable is not easily deformed by external force.

[0004] However, in actual use, the above-mentioned cable is not completely straight during the cable laying process, and the cable is mostly wound in a circular ring when it is rolled up. This causes the internal structure of the cable to easily crack or deviate from the original position, which in turn causes the relative position between the conductor and the support frame to change, affecting the internal stability of the cable, and further affecting the normal operation of the cable. In view of this, we propose an anti-interference cable. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-interference cable to solve the problems raised in the above background technology.

[0008] Conductor, the side wall of the clamp is provided with the conductor, a filling rod is provided on the outer wall of the clamp away from the side where the conductor is provided, and a limiting band is provided on the side wall of the clamp;

[0010] Preferably, the fixed core is arranged in a cylindrical shape, the clamping strips are arranged in a spiral shape on the arc-shaped outer surface of the fixed core, and the clamping strips are arranged in eight groups, and the eight groups of clamping strips are evenly distributed in a circular array on the arc-shaped outer wall of the fixed core to facilitate the embedding installation of the wires and the filling rods.

[0011] Preferably, there are two groups of the limiting belts, and the two groups of limiting belts are arranged in a "V" shape on the side wall of the clamping strip.

[0012] Preferably, the interior of the inflation cavity is filled with an inert gas to ensure that the filling rod can maintain a good pressure-bearing state and a cylindrical shape.

[0013] Preferably, the reinforcement rings are provided in a plurality of groups, and the plurality of groups of reinforcement rings are evenly distributed in the inflation cavity to ensure that the filling rod can continuously maintain a cylindrical shape.

[0014] Preferably, the arc-shaped inner surface of the inner cavity is provided with wave patterns, the inner wall of the protective sleeve is provided with a through hole, and a rubber belt is inserted into the through hole.

[0015] Compared with the prior art, the utility model provides an anti-interference cable with the following beneficial effects:

[0016] 1. The anti-interference cable is provided with a protective mechanism, which cooperates with eight groups of clamping strips arranged on the arc-shaped outer wall of the fixed core to form multiple groups of accommodating cavities in which the wires and the filling rods can be embedded, so that the wires and the filling rods are spirally wrapped around the arc-shaped outer wall of the fixed core, and cooperate with the "V"-shaped limiting belts arranged on both sides of the clamping strips to increase the fit and gripping ability between the filling rod and the wire and the clamping strips, avoid the filling rod and the wire from slipping and detaching from the clamping strips during the use of the cable, ensure that the shape of the wire in the inner cavity is not affected by external interference and can be quickly restored to ensure the normal use of the cable.

Further, the conductor 9 and the filling rod 11 are both spirally embedded in the accommodating cavity 8 to increase the fit and gripping ability between the filling rod 11 and the conductor 9 and the clamping strip 7, so as to avoid the filling rod 11 and the conductor 9 from slipping and detaching from the clamping strip 7 during the use of the cable, thereby affecting the normal operation of the conductor 9.

In addition, several groups of reinforcement rings 13 are provided, and several groups of reinforcement rings 13 are evenly distributed in the inflation cavity 12 to ensure that the filling rod 11 can continue to maintain a cylindrical shape, avoiding excessive deformation and being unable to be used normally, thereby increasing the service life of the filling rod 11.
