Description

Technical Field

[0001] This utility model belongs to the field of cable technology, specifically relating to a high-strength, easily bendable flat cable. Background Technology

[0002] In recent years, the demand for multi-core flat silicone rubber cables has been gradually increasing. In certain situations where long-distance suspension or other reasons require withstanding large tensile forces, flat silicone rubber cables are widely used in special mobile applications due to their flexible structure, convenient laying, excellent bending resistance, and outstanding aging resistance. Flat cables have good compressive strength, but because the internal cores are arranged side by side, they are inconvenient to bend. Utility Model Content

[0003] The purpose of this invention is to provide a high-strength, easily bendable flat cable with a simple structure and an internal reinforcement structure. When bending is required, the reinforcement mechanism guides the internal wiring to be arranged longitudinally, making bending easier. It is highly practical and suitable for widespread application.

[0004] The present invention provides the following technical solution: a high-strength, easily bendable flat cable, comprising single strands and a sheathing layer, wherein the single strands are arranged in an array in the sheathing layer and a filler layer is filled inside the sheathing layer, and a braided layer is provided on the outer sheathing layer; The single strand is fitted with an array of collars. Connecting blocks are installed on both sides of the collar on the central single strand. The connecting blocks are fixed with clamping grooves on both sides. The clamping groove on one side of the central single strand is connected to the collar there through a shaft. The collars on both sides of the single strand are provided with side rails. The inner wall of the clamping groove there is fixed with a sliding rod that is inserted into the side rail.

[0005] Preferably, the filler layer is composed of fine particles, the wrapping layer is insulating rubber, and the braided layer is composed of a cross-shaped coarse-pore metal mesh.

[0006] Preferably, the side rails are located on the front and rear sides of the collar and extend to the upper and lower sides of the collar, the collar is inserted into the clamping groove, and the sliding rod is slidably connected to the side rails.

[0007] Preferably, there is a gap between the collars, the width of which allows the single strand of wire to be bent.

[0008] The beneficial effects of this utility model are: simple structure, internal reinforcement structure, and when bending is required, the reinforcement mechanism guides the internal wiring to be arranged longitudinally, facilitating bending and making it highly practical, as detailed below: This utility model features a collar, through which the internal cores of the cable are connected. The collar provides support for the cable, and collars in the same row are connected by a connecting block. When compressed, the internal single strands are not easily displaced. When the cable needs to be bent, the two sides of the bend are pinched to compress the internal single strands. During this process, the filling layer composed of fine particles can be separated, the soft wrapping layer and braided layer deform, and the clamping groove on the connecting block deflects along the adjacent side rails and slides to the upper and lower sides of the central single strand. At this time, the single strands at this point are arranged longitudinally, and the single strands will not be compressed when bent, thus facilitating bending and laying. Attached Figure Description

[0013] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0014] See Figure 1-2 A high-strength, easily bendable flat cable includes a single-strand wire 1 and a sheathing layer 3. The single-strand wire 1 is an insulating layer wrapped around the wire core. The single-strand wires 1 are arranged in an array in the sheathing layer 3, and a filler layer 2 is filled inside the sheathing layer 3. The filler layer 2 is composed of fine particles, which provides support. If the cable is squeezed from both sides, the single-strand wires 1 can be pushed out of the filler layer 2 and displaced. The sheathing layer 3 is made of insulating rubber. The sheathing layer 3 is covered with a braided layer 4, which is composed of a cross-shaped coarse-pore metal mesh, making the braided layer 4 flexible and more wear-resistant.

[0015] See Figure 1-3 A row of collars 5 is arranged on a single strand 1. When compressed, the collars 5 provide support. There is a gap between the collars 5, which is wide enough to allow the single strand 1 to bend. Connecting blocks 6 are installed on both sides of the collar 5 on the single strand 1 located in the center, so that each single strand 1 is connected as a whole. The connecting blocks 6 are fixed with grooves 7 on both sides. The groove 7 on one side of the single strand 1 in the center is connected to the collar 5 there through the shaft 10. The collars 5 on both sides of the single strand 1 are provided with side rails 8. The inner wall of the groove 7 is fixed with a sliding rod 9 that is inserted into the side rail 8. The side rail 8 is located on the front and rear sides of the collar 5 and extends to the upper and lower sides of the collar 5, so that the adjacent single strand 1 can move above or below it. The collar 5 is inserted into the groove 7, and the sliding rod 9 is slidably connected with the side rail 8, so that the connection between the connecting block 6 and the collar 5 of the single strand 1 is more stable.

[0016] This utility model presents a high-strength, easily bendable flat cable with a simple structure and an internal reinforcement structure. When bending is required, the reinforcement mechanism guides the internal wiring to be arranged longitudinally, facilitating bending. It is highly practical and suitable for widespread application.

[0017] For specific usage, please refer to... Figure 1-3The wire cores inside the cable are connected by collars 5, which support the cable. The collars 5 in the same row are connected by connecting blocks 6. When squeezed, the internal single strands 1 are not easily displaced. When the cable needs to be bent, pinch the two sides of the bend and squeeze the internal single strands 1. During this process, the filling layer 2 composed of fine particles can be separated, the soft wrapping layer 3 and the braided layer 4 are deformed, and the clamping groove 7 on the connecting block 6 deflects along the adjacent side rails 8 and slides to the upper and lower sides of the middle single strand 1. At this time, the single strands 1 at this point are arranged in the longitudinal direction, and the single strands 1 will not be squeezed when bent.
