Description

Technical Field

[0001] This utility model relates to the field of cable technology, specifically to a bending-resistant cable. Background Technology

[0002] Cables are intermediate media specifically used to transmit signals or electricity. They usually contain several conductors and are wrapped with layers of insulation and shielding to prevent the transmission capacity from being slowed down by external interference. These cables are often buried in pipes or walls and are inevitably subjected to compression or bending.

[0003] If such cables are bent, their inner outer layer and sheath will inevitably be squeezed together and wrinkles will form. Over time, the sheath and other materials are prone to cracking, which makes it difficult to maintain the integrity of the cable. If the sheath is broken, the internal signal transmission or power transmission will be affected, causing many inconveniences.

[0004] Now, a new type of bend-resistant cable is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a bending-resistant cable to solve the problem of poor bending resistance mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending-resistant cable, comprising a rubber sheath and an inner cavity. The inner cavity is provided between the front and back sides of the inner side of the rubber sheath, and a retaining sleeve is provided between the front and back sides of the inner cavity. Three sets of grooves are provided between the front and back sides inside the retaining sleeve, and gaskets are fixedly connected to the side walls of the grooves. An insulating layer is attached to the outer side of the gasket, and a metal wire core is fixed inside the insulating layer. A transverse groove is provided at the center of the retaining sleeve, and a slot is provided on the outer side of the transverse groove. A connecting block is fixed in the transverse groove. Protrusions are fixed on both sides of the connecting block, and a movable piece is movably sleeved between the front and back sides of the protrusions. Circular grooves are provided at the front and rear ends inside the movable piece. A water-proof cylinder is sleeved on the outer side of the rubber sheath. An outer connecting sleeve is fixed between the front and back sides of the outer side of the rubber sheath, and an inner connecting sleeve is fixed between the front and back sides of the outer side of the water-proof cylinder.

[0007] As a further technical solution of this utility model, the circular groove is sleeved on the outside of the protrusion, and the connecting block is symmetrically installed on both sides of the movable piece.

[0008] As a further technical solution of this utility model, the inner connecting sleeve and the outer connecting sleeve are of equal length, and the inner connecting sleeve and the outer connecting sleeve are arranged in a concentric circle.

[0009] As a further technical solution of this utility model, support blocks are fixed on the upper part and the left and right sides of the inside of the rubber sleeve, and arc-shaped pressure blocks are fixed on the surface of the support blocks, and the inner cavity is filled with filler material.

[0010] As a further technical solution of this utility model, the inner wall of the water-proof cylinder is provided with locking blocks, the inside of the surface of the rubber sleeve is provided with a locking groove, the front and back of the inside of the rubber sleeve are provided with a hole groove, and the front and back of the hole groove are connected with nylon thread.

[0011] As a further technical solution of this utility model, the card block is embedded in the card slot, and the holes and slots are distributed in the gaps of the card slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the bending-resistant cable not only improves the bending resistance and protects the internal core, but also maintains the integrity of the surface structure;

[0013] By fixing a connecting block in the transverse groove, the connecting block passes through the groove and is installed in the transverse groove at the center. The adjacent sleeves will be segmented and fitted onto the surface of the metal wire core. The two sides of the connecting block are respectively fitted onto the surface of the protrusion through the circular groove. When the internal metal wire core is bent, under the support of the inner connecting sleeve and the outer connecting sleeve, the rubber sleeve and the water-proof cylinder can be bent slightly, and the cable can be bent from multiple points, thereby improving the bending resistance of this product.

[0014] By filling the inner cavity with filler material, the metal wire core with insulation layer will be fixed in the arc-shaped groove of the ferrule and fit against the gasket on the side wall of the groove. The outer side of the metal wire core will contact the arc-shaped pressure block, and the arc-shaped pressure block will be fixedly connected to the rubber sleeve. This can prevent the metal wire core from falling out of the ferrule and maintain the stability of the internal structure of the cable in conjunction with the filler material in the inner cavity.

[0015] By attaching a water-proof cylinder to the outside of the rubber sheath, and fixing the water-proof cylinder to the inner wall and embedding it in the slot, the rubber sheath and the water-proof cylinder can be prevented from separating. The adjacent rubber sheaths are connected by nylon threads in the slots, forming a stable shielding layer on the surface of the metal core, preventing external moisture from entering the cable and ensuring the safety of the inner structure of the cable.
