Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a flat braided cable. Background Art

[0002] As a multi-core cable, flat cable was first used in electronic instruments. It has the advantages of easy bending, small wiring space, and neat arrangement. The installation process can quickly determine the positions of the two ends of different cables, and it is widely used.

[0003] The structure of the existing flat cable between two adjacent cable cores is too weak and can be easily torn, resulting in the entire flat cable being divided into several parts, which is not conducive to the installation and use of the flat cable. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provides a flat braided cable. The specific technical solution is as follows:

[0005] A flat braided cable comprising:

[0006] A plurality of cable cores, wherein the plurality of cable cores are arranged side by side;

[0007] A skeleton is arranged between the two groups of adjacent cable cores, and both sides of the skeleton are provided with integrally formed limit plates, and the limit plates are fixedly sleeved with the cable cores. A cavity is arranged inside the skeleton, and when the two groups of adjacent cable cores are subjected to a pulling force moving away from each other or an extrusion force moving toward each other, the skeleton provides radial buffering and tensile resistance with the cooperation of the cavity;

[0008] The wrapping layer covers the skeleton and the plurality of cable cores.

[0009] In the above technical solution, the cavity in the frame allows the frame to have a certain stretching buffer space in the vertical and horizontal directions. When the cable is subjected to vertical or horizontal tension, the arc-shaped portion of the frame can be deformed under the action of the tension, thereby improving the tensile resistance of the cable and ensuring that the flat cable is not easily torn apart or the cable core is squeezed together.

[0010] The positions of multiple groups of cable cores are locked relative to each other through the cooperation of the skeleton and the limit plates, so that the cable cores remain in a linear arrangement, which effectively enhances the overall strength of the flat cable and has high structural stability.

[0011] As an improvement of the above technical solution, a shielding wire is arranged in the cavity to shield the signal between two groups of adjacent cable cores.

[0012] As an improvement of the above technical solution, the shielding wire includes spirally wound copper wires and multiple groups of aramid fibers.

[0013] As an improvement of the above technical solution, the radial cross-section of the skeleton is circular or elliptical, and a plurality of groups of grooves are arranged on the surface of the skeleton.

[0014] As an improvement of the above technical solution, the wrapping layer includes a filling layer, a shielding layer and a braided layer from the inside to the outside.

[0015] Beneficial effects of the utility model:

[0016] The cavity in the frame provides a certain stretching buffer space in the vertical and horizontal directions. When the cable is subjected to vertical or horizontal tension, the arc-shaped portion of the frame can be deformed under the tension, thereby improving the tensile resistance of the cable and ensuring that the flat cable is not easily torn apart or the cable core is squeezed together.

[0017] The positions of multiple groups of cable cores are locked relative to each other through the cooperation of the skeleton and the limit plates, so that the cable cores remain in a linear arrangement, which effectively enhances the overall strength of the flat cable and has high structural stability.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] A flat braided cable, comprising a plurality of cable cores 50, wherein the plurality of cable cores 50 are arranged side by side;

[0024] The skeleton 40 is arranged between the two groups of adjacent cable cores 50. The two sides of the skeleton 40 are provided with integrally formed limit plates 42. The limit plates 42 are fixedly sleeved with the cable cores 50. A cavity 41 is arranged inside the skeleton 40. When the two groups of adjacent cable cores 50 are subjected to a pulling force moving away from each other or an extrusion force moving toward each other, the skeleton 40 provides radial buffering and tensile resistance with the cooperation of the cavity 41.

[0025] The wrapping layer covers the skeleton 40 and the plurality of cable cores 50 .

[0026] The skeleton 40 is made of memory alloy material, and the cavity 41 inside the skeleton 40 enables the skeleton 40 to have a certain stretching buffer space in the vertical and horizontal directions. When the cable is subjected to vertical or horizontal tension, the skeleton 40 is subjected to the tension, and the arc-shaped part of the skeleton 40 can be deformed to improve the tensile resistance of the cable, thereby ensuring that the flat cable is not easily torn apart or the cable core 50 is squeezed together. The skeleton 40 and the limiting plate 42 cooperate with each other to lock the positions of multiple groups of cable cores 50 with each other, so that the cable cores 50 maintain a linear arrangement, effectively enhancing the overall strength of the flat cable, and having high structural stability. In addition, the limiting plate 42 can protect the cable core 50, which can greatly reduce the damage to the cable core 50.

[0027] In one embodiment, a shielding wire 60 is disposed in the cavity 41 for shielding the signal between two groups of adjacent cable cores 50 . The shielding wire 60 can shield the signal and prevent the magnetic fields of the two cable cores 50 from interfering with each other.

[0028] In one embodiment, the shielding wire 60 includes a spirally wound copper wire 62 and a plurality of groups of aramid fibers 61 . The plurality of groups of aramid fibers 61 can improve the tensile strength of the copper wire 62 .

[0029] In one embodiment, the radial cross-section of the skeleton 40 is circular or elliptical, and a plurality of groups of grooves are arranged on the surface of the skeleton 40. The circular or elliptical skeleton 40 is convenient for deformation and restoration to the initial state. The plurality of groups of grooves are arranged to facilitate the filling layer 30 to enter the grooves after filling, thereby increasing the contact area, limiting and fixing the position of the skeleton 40, and increasing the stability of the connection between the filling layer 30 and the skeleton 40.

[0030] The wrapping layer includes a filling layer 30, a shielding layer 20 and a braided layer 10 from the inside to the outside. The shielding layer 20 is woven from metal wires, which can be copper or aluminum. The filling layer 30 completely covers the cable core 50, the skeleton 40 and the limiting plate 42. The material of the filling layer 30 can be a cross-linked polyethylene polymer material with fire retardant effect. The braided layer 10 is woven from nylon material.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
