[0013] (III) Beneficial effects

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The vehicle-mounted data cable, by arranging a first flame retardant layer, a second flame retardant layer, a cavity, an inner enclosure and a filling layer, utilizes the different fire resistance characteristics of the first flame retardant layer and the second flame retardant layer to make the cable body multi-stage flame retardant, and through the cooperation of the cavity and the inner enclosure, the cable body has a certain elasticity, which can better protect the wire. At the same time, when the cable body burns, the ruptured cavity can use air to diffuse the fire extinguishing agent in the inner enclosure, effectively reducing the combustion range, thereby protecting electronic equipment and human body, and reducing safety hazards.

[0016] 2. The vehicle-mounted data cable is provided with a tough rubber strip, a shaping mesh and a filling layer. Since the shaping mesh is made of aluminum, it is easy to deform. Combined with the tough rubber strip and the shaping mesh structure, the cable body not only has good toughness, but also is easy to adjust and use by plastic deformation as needed, which facilitates the installation and use of the cable body.

[0017] 3. The vehicle-mounted data cable is provided with a rubber outer layer, an outer sleeve, a slider, a slide groove and an annular groove. The slide groove makes the cable body have good anti-slip properties. Since the outer sleeve has a certain magnetic adsorption function, the outer sleeve can slide through the cooperation of the slider and the slide groove, which makes it easy to adsorb the outer sleeves to each other and connect and fix the two cable bodies. Therefore, after the cable body is installed, it is convenient to bundle the cables, which can effectively prevent the safety hazards caused by multiple cable bodies being entangled together.

DETAILED DESCRIPTION

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] like Figure 1-3 As shown, the present invention provides a technical solution: a vehicle-mounted data cable, comprising a cable body 1, a first flame retardant layer 8 is arranged in the cable body 1, a second flame retardant layer 9 is bonded to the inner wall of the first flame retardant layer 8, four tough rubber strips 2 are fixedly connected in the first flame retardant layer 8, a plurality of cavities 13 are arranged in the first flame retardant layer 8, two inner enclosures 14 are arranged in each of the plurality of cavities 13, a shaping mesh body 3 is arranged in the tough rubber strip 2, a rubber outer layer 4 is arranged on the outer wall of the cable body 1, and an outer sleeve 5 is sleeved on the outer wall of the rubber outer layer 4.

[0024] Specifically, Figure 1As shown, the second flame retardant layer 9 is formed by bonding ceramic silicone and glass fiber, the first flame retardant layer 8 is made of fire-resistant fiber material, and the fire resistance of the second flame retardant layer 9 is greater than that of the first flame retardant layer 8. Due to the poor flame retardancy of the first flame retardant layer 8, the second flame retardant layer 9 with better flame retardancy can provide better flame retardant protection for the cable body 1, and facilitate the rapid cracking of the cavity 13 during combustion, so as to facilitate the fire reduction through the inner package 14. The outer wall of the shaping mesh 3 is fixedly connected to the inner wall of the tough rubber strip 2. The shaping mesh 3 is an aluminum mesh structure. Through the structural coordination of the tough rubber strip 2 and the shaping mesh 3, the cable body 1 can have good toughness and elasticity, and can be conveniently adjusted according to installation needs. The shape of the cable body 1 is convenient for users to quickly install and connect the cable body 1, which is more convenient. The inner wall of the outer jacket 5 is fixedly connected with several A slider 6 is provided, one end of which is clamped in the slide groove 7. The outer sleeve 5 is a rubber sleeve wrapped with a magnetic material. An annular groove 12 is provided on the outer wall of the outer sleeve 5. Through the mutual adsorption between the outer sleeves 5, the two cable bodies 1 can be conveniently connected and fixed, which plays a role in facilitating the bundling of cables. At the same time, the annular groove 12 provided on the outer wall of the outer sleeve 5 can be used to bind the cable bodies 1 by binding ropes through the annular groove 12 when storing more cable bodies 1, so that the cable bodies 1 can be neatly stored when they are transported. A filling layer 11 is provided on the inner wall of the second flame retardant layer 9. The filling layer 11 is a mesh structure. Three conductors 10 are arranged in the filling layer 11. Through the mesh structure of the filling layer 11, the cable body 1 is not only tightly connected in structure, but also has good elastic protection performance, which effectively guarantees its service life and makes its manufacturing cost lower.

[0025] Specifically, Figure 2 As shown, the outer wall of the rubber outer layer 4 is provided with a plurality of slide grooves 7, which are distributed in a ring shape about the central axis of the rubber outer layer 4. Through the action of the plurality of slide grooves 7, the friction between the cable body 1 and the object can be increased in cooperation with the rubber outer layer 4, thereby facilitating the storage of the cable body 1 and facilitating its stable installation and fixation.

[0026] Specifically, Figure 3 As shown, the inner package 14 is provided with a fire extinguishing material, and the inner package 14 is made of a plastic film. Due to the characteristics of the inner package 14 being made of a plastic film, it can be melted quickly when a fire occurs, thereby facilitating the dispersion of the fire extinguishing material and providing better flame retardancy, thereby effectively preventing the expansion of the combustion range.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
