Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to an adaptive bending protection cable. Background Art

[0002] Cables are prone to bending during use, and frequent bending can lead to the following problems: the conductor inside the cable may break or crack due to repeated bending; common copper conductors are prone to local deformation in areas where stress is concentrated due to frequent bending, resulting in reduced conductivity; the external insulation layer may wear, crack, or even peel; for example, the molecular structure of the polyvinyl chloride (PVC) insulation layer will gradually be destroyed due to mechanical stress during repeated bending, thereby reducing the insulation effect;

[0003] Bending may increase the resistance of the cable and cause changes in parameters such as capacitance and inductance. For example, when the internal conductor of the cable is broken or has poor contact, the resistance will increase significantly, affecting the normal transmission of current. To solve the problem of cables being easily damaged when frequently bent, an adaptive bend protection cable is provided to solve the above problems. Utility Model Content

At the same time, the second positioning piece is arranged opposite to the first positioning piece, and the second positioning piece and the first positioning piece are fixedly connected by a buckle, and the distance between the buckles is consistent.

[0006] Preferably, the protective rubber sleeve is a cylindrical structure made of rubber material, and the axial section between the protective rubber sleeve and the cable body is a concentric circle structure.

[0007] Preferably, a plurality of heat dissipation holes are evenly formed on the surface of the protective rubber sleeve, and the distances between the heat dissipation holes are consistent.

[0008] Preferably, the heat dissipation hole is rectangular and is set through the protective rubber sleeve, and the two ends of the heat dissipation hole are set in an arc shape.

[0009] Preferably, a plurality of groups of through holes are evenly formed on the surfaces of the first positioning piece and the second positioning piece, and limiting columns are inserted through the through holes on the first positioning piece and the second positioning piece.

[0010] Preferably, a limiting plate is fixedly installed at one end of the limiting column, and a lock buckle is fixedly installed at the end of the limiting column away from the limiting plate. At the same time, the lock buckle is conically arranged, and the diameters of the limiting column and the perforation are consistent, and the diameters of the limiting plate and the lock buckle are larger than the diameter of the limiting column.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model sequentially inserts a locking buckle with a tapered end portion of the limiting piece through the through-holes of the first and second positioning pieces. The tip of the locking buckle can open the soft through-holes and then wrap around the outside of the limiting post, thereby achieving a fixed installation between the first and second positioning pieces. The protective rubber sleeve can be stably wrapped around the outside of the cable body and will not fall off.

[0013] 2. The utility model reduces the bending angle of the cable body during frequent use by providing a protective rubber sleeve, achieving adaptive bending protection for the cable. This can buffer the stress generated during bending, effectively reducing the possibility of breakage or cracking of the internal conductor of the cable.
