Description

Technical Field

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

[0002] A cable is a combination of conductors used to transmit electrical energy or signals, typically consisting of one or more conductors encased in a protective layer.

[0003] Currently, during the laying of some cables, it is necessary to connect the battery cores in adjacent cable sections according to the laying length. However, after the protective layer on the surface of some battery cores used for connection is stripped off, they will lack protection in subsequent use. When workers pull the cable to move it, the pulling force can easily be applied directly to the connection part of the battery core, thereby affecting the stability of the connection part. Furthermore, if the connection part of the cable bends during the pulling process, the stability of the connection part of the battery core can also be affected. Utility Model Content

[0004] The purpose of this invention is to provide a tensile-resistant cable to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tensile-resistant cable, comprising a core body, and further comprising: A filling layer is fitted onto the surface of the battery cell body. A reinforcing rib is fixedly inserted inside the filling layer. An armor layer, a shielding layer, an oxygen barrier layer, and a wear-resistant layer are sequentially fitted onto the surface of the filling layer from the inside out. An insulating layer is fixedly fitted onto the surface of the wear-resistant layer. A threaded sleeve is slidably fitted on both sides of the surface of the insulating layer. An extrusion ring is threaded on the surface of the threaded sleeve. A plurality of clamping plates are fixedly connected to one end of the threaded sleeve. The inner wall of the extrusion ring is in contact with the surface of the clamping plate. The other ends of the two threaded sleeves are respectively equipped with protective mechanisms and fixedly connected with connecting rings, and the surface of the connecting rings is equipped with a moving mechanism.

[0006] Preferably, the armor layer is made of multiple steel strips wound and woven together, and the wear-resistant layer is made of ultra-high molecular weight polyethylene.

[0007] Preferably, the filler layer is made of a halogen-free flame-retardant material, and the oxygen barrier layer is made of aluminum hydroxide.

[0008] Preferably, the protective mechanism includes a fixed ring fixedly connected to a threaded sleeve, a protective ring and several extension rods fixedly connected to the surface of the fixed ring, and a disc fixedly connected to one end of each extension rod.

[0009] Preferably, the moving mechanism includes a moving frame that is slidably sleeved on the surface of the connecting ring. The moving frame has a groove inside, and a tension spring is fixedly connected inside the groove. One end of the tension spring is fixedly connected to the surface of the connecting ring. A turntable is rotatably connected to the surface of the moving frame. A slot is formed on the surface of the turntable. The turntable slides through the connecting ring and the moving frame and contacts the inner wall of the slot.

[0010] Preferably, the guide groove is arc-shaped, and the upper and lower surfaces of the insulating layer are provided with sliding grooves. The upper and lower surfaces of the inner wall of the threaded sleeve are fixedly connected with sliders, and the surface of the sliders is slidably connected to the inner wall of the sliding groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention increases the cable's bending resistance by adding reinforcing ribs, reducing the possibility of the battery core bending. After the battery cores of the two cable sections are connected, the protective mechanism, in conjunction with the connecting ring, the moving mechanism, and the turntable, not only provides protection to the connection part of the battery core, but also prevents the tension from being fully applied to the connection part of the battery core when the cable is pulled. This solves the problem that in some current cables, the surface of the battery core lacks protection after connection, making it susceptible to direct stress due to subsequent cable movement, which affects the stability of the battery core connection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6 As shown, a tensile-resistant cable includes a core body 1, a filling layer 2 covering the surface of the core body 1, a reinforcing rib 7 fixedly penetrating the interior of the filling layer 2, the reinforcing rib 7 can increase the strength of the cable during use, an armor layer 3 covering the surface of the filling layer 2, and a shielding layer 4 covering the surface of the armor layer 3.

[0016] An oxygen barrier layer 5 is fitted on the surface of the shielding layer 4, and an abrasion-resistant layer 6 is fitted on the surface of the oxygen barrier layer 5. The abrasion-resistant layer 6 can increase the abrasion resistance of the cable, thereby protecting the internal core body 1. The oxygen barrier layer 5 can reduce the flame retardant effect of the cable. An insulation layer 8 is fixedly fitted on the surface of the abrasion-resistant layer 6. The insulation layer 8 is made of rubber.

[0017] A flow channel 9 is provided on the surface of the insulation layer 8. The flow channel 9 is arc-shaped, which can prevent water from remaining on the surface of the insulation layer 8.

[0018] The upper and lower surfaces of the insulating layer 8 are provided with grooves 10, and the two sides of the insulating layer 8 are slidably fitted with threaded sleeves 11. The upper and lower surfaces of the inner wall of the threaded sleeve 11 are fixedly connected with sliders 12. The surface of the sliders 12 is slidably connected to the inner wall of the grooves 10. The sliders 12 and the grooves 10 work together to guide the movement of the threaded sleeves 11.

[0019] A number of clamping plates 13 are fixedly connected to one end of the threaded sleeve 11. When the clamping plates 13 are squeezed, the bottom of the clamping plates 13 can be inserted into the surface of the insulation layer 8 to restrict the position of the threaded sleeve 11 on the surface of the insulation layer 8, so that the operator can move and adjust the threaded sleeve 11 according to the position of the cable joint.

[0020] A compression ring 14 is threaded onto the surface of the threaded sleeve 11. The inner wall of the compression ring 14 contacts the surface of the clamping plate 13. The compression ring 14 can move on the surface of the threaded sleeve 11 to compress the clamping plate 13 so that the bottom of the clamping plate 13 can be inserted into the surface of the insulating layer 8.

[0021] One side of the inner wall of the extrusion ring 14 is inclined so that the extrusion ring 14 can better compress the clamping plate 13. The armor layer 3 is made of multiple steel strips wound and woven together. The armor layer 3 can increase the torsional resistance of the cell body 1.

[0022] The filling layer 2 is made of halogen-free flame-retardant material, and the oxygen barrier layer 5 is made of aluminum hydroxide. When an external fire source affects this cable, the oxygen barrier layer 5 can release a large amount of moisture to reduce the ambient temperature and form a non-melting and non-flammable aluminum oxide hard shell to isolate it from contact with the outside air, thereby protecting the battery cell body 1.

[0023] The wear-resistant layer 6 is made of ultra-high molecular weight polyethylene (UHMWPE), a thermoplastic engineering plastic with a linear structure and excellent comprehensive performance, which can effectively improve the wear resistance of the cable.

[0024] The other ends of the two threaded sleeves 11 are respectively equipped with protective mechanisms 15 and fixedly connected with connecting rings 16. The surface of the connecting rings 16 is equipped with a moving mechanism 17.

[0025] The protective mechanism 15 includes a fixed ring 151 fixedly connected to the threaded sleeve 11. A protective ring 152 is fixedly connected to the surface of the fixed ring 151. Several extension rods 153 are fixedly connected to the surface of the fixed ring 151. A disc 154 is fixedly connected to one end of each extension rod 153. The protective ring 152 can protect the connection part of the two cable sections during use.

[0026] The moving mechanism 17 includes a moving frame 171 slidably sleeved on the surface of the connecting ring 16. A groove 172 is formed inside the moving frame 171, and a tension spring 173 is fixedly connected inside the groove 172. One end of the tension spring 173 is fixedly connected to the surface of the connecting ring 16. A turntable 18 is rotatably connected to the surface of the moving frame 171, and a slot 19 is formed on the surface of the turntable 18. A disc 154 slides through the connecting ring 16 and the moving frame 171 and contacts the inner wall of the slot 19. The operator moves the disc 154... After passing through the connecting ring 16 and the moving mechanism 17, 54 can squeeze and rotate the turntable 18 to adjust the angle of the slot 19. The position of the extension rod 153 can be fixed by the cooperation between the slot 19 and the disc 154, thereby restricting the position of the protective ring 152 so as to protect the cable connection through the protective ring 152. In this process, the protective mechanism 15, the connecting ring 16, the moving mechanism 17 and the turntable 18 work together to increase the tensile strength of the cable connection.

[0027] Working principle: When connecting the battery core 1 of two adjacent cables, the worker can peel off the filling layer 2, armor layer 3, shielding layer 4, and oxygen barrier layer 5 on the surface of the battery core 1. At this time, the protection of the battery core 1 is reduced. The worker first moves the threaded sleeve 11 to the appropriate position, and then rotates the compression ring 14. The compression ring 14 moves on the surface of the threaded sleeve 11 and compresses the clamping plate 13. The clamping plate 13 inserts into the surface of the insulation layer 8, which can restrict the position of the threaded sleeve 11. After that, the worker can pass the extension rod 153 and the disc 154 on one side of the cable surface through the connecting ring 1 on the other side of the cable surface. 6. The operator squeezes and rotates the turntable 18. During this process, the disc 154 passes through the slot 19 and is placed on the surface of the turntable 18. The operator can adjust the position of the slot 19 by rotating the turntable 18. At this time, the slot 19, together with the extension rod 153 and the disc 154, can reinforce the position of the protective mechanism 15. The protective ring 152 is fitted on the surface of the cable connection and protects the connection part of the cable. When the cable is pulled, the protective mechanism 15, together with the moving mechanism 17 and the turntable 18, can prevent the entire pulling force from being applied to the cable connection, thereby increasing the tensile strength of the cable.
