[0003] In the patent application with application publication number CN216353420U, it includes a conductive wire and a protective component, the conductive wire is fixedly installed with an insulating layer on the outside, and the insulating layer is fixed with a silk layer on the outside, the silk layer is provided with a protective frame on the outside, and the protective frame is provided with an insulating rubber layer on the outside, the insulating rubber layer is connected to a flexible insulating layer on the outside, and a shielding layer is fixed to the outside of the flexible insulating layer, the shielding layer is connected to a limiting belt on the outside, and a fixing glue is provided on the upper end of the limiting belt, and the protective component is provided at the upper and lower ends of the shielding layer. The conductive wires of this flexible flat cable are equidistantly arranged in sequence to the same horizontal line, and the insulating layer and the silk layer are provided on the outside to protect and insulate it. The silk layer can increase the toughness of the insulating layer and prevent it from cracking. The protective frame is concave and convex, wrapping the conductive wire inside, and separating each conductive wire to prevent one conductive wire from affecting other conductive wires when it is damaged, causing a wider range of losses.

[0004] In the above patent, if the flexible flat cable is subjected to strong external squeezing, the outer surface or the internal copper wire of the flexible flat cable may be damaged. When the flexible flat cable breaks due to pressure, it will cause power outages, short circuits and other problems that will affect normal use. Summary of the invention

[0005] The object of the present invention is to provide a flexible flat cable with compression resistance to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution of the present invention is: a flexible flat cable with pressure resistance, comprising a flat cable body and a protection mechanism and a guard mechanism arranged outside the flat cable body for protecting the flat cable body, the protection mechanism comprising a lower shell and an upper shell, the lower shell and the upper shell have the same structure, the lower shell and the upper shell are symmetrically arranged, the flat cable body is located between the lower shell and the upper shell to prevent the flat cable body from being damaged by pressure;

[0007] The upper shell is provided with a through hole, baffles are fixedly arranged on both sides of the lower side of the upper shell, a placement groove is provided inside the upper shell, and a buffer cotton for protecting the flat wire body is fixedly arranged inside the placement groove.

[0008] Preferably, the lower shell includes an insulating layer, the lower shell is fixedly connected to the insulating layer in the upper shell, a fireproof layer is provided on one side of the insulating layer, a buffer layer is provided on one side of the fireproof layer, and a wear-resistant coating is provided on one side of the buffer layer.

[0009] Preferably, the protection mechanism comprises two groups of protection frame assemblies fixed to the outer sides of the lower shell and the upper shell, and a plurality of connecting pipes are arranged between the two groups of protection frame assemblies.

[0010] Preferably, the protective frame assembly includes a protective frame fixedly arranged on the outside of the lower shell and the upper shell, two grooves are provided on the side of the protective frame away from the lower shell and the upper shell, a connecting hole is provided on the inside of the protective frame close to the lower shell and the upper shell, the connecting hole is connected with the through hole, fixing plates are fixedly arranged under both ends of the protective frame, and two protruding rods are fixedly connected under the protective frame.

[0011] Preferably, a through hole is provided on the fixing plate, a cavity is provided inside the protection frame, and the connecting hole is connected to the cavity.

[0012] Preferably, an air flow channel is provided in the connecting pipe, and the air flow channel is connected to the cavity in the protective frame.

[0013] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0014] (1) A lower shell and an upper shell are provided on the outside of the flat wire body. When a foreign object contacts the connecting tube, the air in the air flow channel is squeezed into the cavity in the protective frame. The pressure continues downward and is transmitted to the lower shell and the upper shell through the connecting tube. The pressure squeezes the buffer cotton, causing part of the air in the buffer cotton to enter the protective frame, so that the air is first discharged through the air flow to reduce the damage to the flat wire body caused by the pressure. There is still some air in the buffer cotton, which reduces the pressure on the flat wire body. The buffer cotton, the lower shell and the connecting tube below the flat wire body protect the upper part of the flat wire body to prevent the presence of debris and the two-way squeezing force from damaging the flat wire body. The setting of the wear-resistant coating increases the wear resistance, preventing the lower shell from being damaged by friction when subjected to oblique pressure, gas leakage, and weakening the protection of the flat wire body;

[0015] (2) When using a group of flat wire bodies, the protruding rod is in contact with the ground so that only the protruding rod is in contact with the connecting tube and the ground. The protective frame assembly can be fixed by screwing through the through hole on the fixing plate to prevent the flat wire bodies from being rubbed when placed, causing damage to the connecting tube and reducing the protection of the flat wire bodies. When multiple groups of flat wire bodies are needed, the protruding rod of one group of flat wire bodies is inserted into the groove of the lower group of flat wire bodies so that the two groups of flat wire bodies are fixed together. Then, the two or more groups of flat wire bodies are fixed together by cable ties or long screws passing through the round holes on the fixing plate, thereby improving the neatness of the wiring.
