Technical Field

[0001] The present invention relates to the field of wire harness components, and particularly to a wire harness component for wire and cable with a combing function. Background Art

[0002] A wire harness is a wiring component that connects various electrical devices in an automotive circuit, and is composed of an insulating sheath, a wiring terminal, a wire, an insulating wrapping material, etc.

[0004] Therefore, it is very necessary to invent a wire harness component for wire and cable with a combing function to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a wire harness component for wire and cable with a combing function to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A wire harness component for wire and cable with a combing function, including a wire combing substrate, a wire combing plate is arranged above the wire combing substrate, a wire combing hole for the cable to pass through is formed between the wire combing plate and the wire combing substrate, a plurality of groups of the wire combing holes are arranged in a circular hole structure, lower fixing plates are fixedly arranged on the front and rear sides of the bottom of the wire combing substrate, reserved threaded holes are arranged on the lower fixing plates, side fixing plates are fixedly arranged on both side surfaces of the mutually close ends of the wire combing substrate and the wire combing plate, two corresponding side fixing plates are in movable contact with each other, two corresponding side fixing plates are fixed by a connecting screw rod, both the upper and lower ends of the connecting screw rod are in threaded fit with fixing nuts, and the two fixing nuts are respectively in movable contact with the mutually far ends of the two side fixing plates. A cleaning component for cleaning the surface of the cable and an isolation component for isolating the cable are arranged inside the wire combing hole;

[0007] The isolation component includes a first annular groove provided at the inner circle of the wire management hole. A rigid outer support ring body is fixedly provided on the inner wall of the first annular groove. A thermosensitive metal unit is fixedly provided on the inner wall of the rigid outer support ring body. A cutting unit is fixedly provided on the inner wall of the thermosensitive metal unit. The cutting units are arranged in a circular array and are equidistantly arranged in multiple groups around the inner wall of the thermosensitive metal unit. At the inner circle position of the multiple groups of cutting units, there is a rubber blocking pad fixed at the opening position connecting the first annular groove to the inside of the internal wire core assembly. The thermosensitive metal unit, the rigid outer support ring body, and the cutting unit are all arranged in the first annular groove. The surfaces of the wire management substrate and the wire management card board that face each other are both in a semi-circular groove structure, and the two semi-circular groove structures form the wire management hole. The rigid outer support ring body, the thermosensitive metal unit, and the rubber blocking pad are all distributed in two semi-circular structures, and the two rigid outer support ring bodies, thermosensitive metal units, and rubber blocking pads are respectively arranged in the two semi-circular groove structures;

[0008] The cable includes an inner internal wire core assembly and an insulating outer skin covering the outside of the internal wire core assembly. The internal wire core assembly includes a conductive core body and a protection ring sleeved outside the conductive core body. The protection ring is fixedly sleeved outside the conductive core body and is arranged in multiple groups at equal distances. Both ends of the protection ring are provided with conical surfaces. Magnetic suction rings and rubber buffer rings are fixedly provided at both ends of the protection ring. The rubber buffer ring is arranged on the side of the magnetic suction ring away from the middle of the protection ring. A reserved shearing section is formed between adjacent two groups of protection rings.

[0009] Preferably, rubber rings are movably attached to both ends of the protection ring. The rubber rings are fixed on the inner wall of the insulating outer skin. A vacuum chamber is formed between the inside of the insulating outer skin and the outside of the conductive core body. The vacuum chamber is divided into multiple groups by the rubber rings.

[0010] Furthermore, an isolation component is provided inside the wire management hole. When the isolation component is heated, it can cut off and isolate the position where the cable passes through the wire management hole, preventing the spread of fire from one side of the wire management card board to the other side when a fire occurs in the cable on one side of the wire management card board. And the cleaning component can clean the surface of the cable passing through the wire management hole. While the wire management card board serves the purpose of wire management for the cable, it can also clean the surface of the cable and prevent the spread of fire.

[0011] Preferably, the cleaning component includes a second annular groove provided on the inner wall of the wire management hole. A support spring is fixedly welded at the bottom of the second annular groove. A wiping cotton ring is fixedly provided at the end of the support spring. The wiping cotton ring is movably arranged in the second annular groove, and the inner circle of the wiping cotton ring is movably attached to the outer circle of the insulating outer skin.

[0012] Wherein, when the cable passes through the position of the cable management hole, the supporting spring abuts against the wiping cotton ring and fits around the outer circle of the insulating outer sheath, thereby cleaning the surface of the cable passing through the cable management hole position. The supporting spring abuts against the wiping cotton ring to ensure that the wiping cotton ring is always fitted around the outer circle of the insulating outer sheath, achieving the purpose of conveniently cleaning the cable.

[0013] Preferably, a set of the second annular grooves are provided on each side of the first annular groove. The first annular groove is provided at the middle position of the cable management hole. The wiping cotton ring includes two semi-circular wiping cotton strips, and the two wiping cotton strips are mutually abutted at the head and tail.

[0014] In the device, a set of the second annular grooves are provided on each side of the first annular groove, which is convenient for double cleaning of the cables entering and exiting from both sides of the cable management hole, and has good cleanliness. The wiping cotton ring includes two semi-circular wiping cotton strips, and the semi-circular wiping cotton strips are convenient for individual replacement and maintenance when disassembling and assembling the cable management substrate and the cable management card board, without affecting the extraction of the cable from the cable management hole.

[0015] Preferably, several groups of cable management card boards are spliced above the cable management card board above the cable management substrate. A cable management hole for the cable to pass through is formed between adjacent cable management card boards. Side fixing plates are also fixedly welded on both side surfaces at the upper end of the cable management card board. When adjacent cable management card boards are spliced with each other, they are fixed by connecting screws on the two side fixing plates.

[0016] Specifically, several groups of cable management card boards can be spliced according to the number of cables. When multiple groups of cable management card boards are spliced with each other, they are fixed by the side fixing plates and the connecting screws on the side fixing plates, which is convenient for connection. Generally, three cable management holes are provided between the cable management substrate and the cable management card board. When the total number of cables exceeds three, several groups of cable management card boards can be spliced above the cable management card board above the cable management substrate, which is convenient for splicing and use according to the number of cables. The cable management substrate is integrally fixed to the bottom through the lower fixing plate, and the screw only needs to pass through the reserved threaded hole, which is convenient for fixing.

[0017] Preferably, the cutting unit has a triangular tooth-like structure. The cutting units are distributed at intervals along the thermosensitive metal unit. The gap between adjacent cutting units is the gap for the thermosensitive metal unit to expand and contract and squeeze the movement when multiple cutting units are mutually abutted. When multiple cutting units are mutually abutted, the tips of multiple cutting units are also mutually abutted.

[0018] It should be noted that when the cable on one side of the cable management card catches fire, the high-temperature heat will be transferred to the thermosensitive metal unit in the middle of the cable hole through the side of the cable and the cable management card. When the thermosensitive metal unit is heated, it will expand and deform. Since the outer rigid outer support ring body of the thermosensitive metal unit cannot be elastically deformed, when the thermosensitive metal unit expands and deforms due to heat, it will squeeze towards the middle of the cable hole. When the extrusion reaches the limit, the sides of multiple cutting units fit together, and the tips of multiple cutting units fit together, thus cutting off the cable. And both the thermosensitive metal unit and the cutting unit are made of non-conductive and fire-blocking materials. Therefore, it plays a role in cutting off the cable to avoid the spread of fire and power transmission. In the above, the cutting unit can use ceramic materials, and the thermosensitive metal unit can use insulating thermosensitive materials, etc.;

[0019] When preventing the spread of fire, it is necessary to ensure the normal transmission of electricity. The cutting unit and the thermosensitive metal unit can both use conductive metal materials, etc. This will not be elaborated here, and specific materials can be selected according to actual needs to achieve the purpose of separately preventing the spread of fire, and the structural design is reasonable.

[0020] Preferably, the cross-section of the rigid outer support ring body is in a concave-shaped structure, the thermosensitive metal unit is fixed at the bottom of the concave-shaped structure of the rigid outer support ring body, the thickness of the thermosensitive metal unit is the same as the width of the concave shape inside the rigid outer support ring body, and the cutting unit on the surface of the thermosensitive metal unit fits on the outer circle of the rubber blocking pad.

[0021] During operation, when the thermosensitive metal unit elastically deforms, it can just elastically deform along the concave-shaped structure inside the rigid outer support ring body towards the inner circle of the cable hole. The rubber blocking pad is provided to ensure that the cable is not cut by the cutting unit under normal use conditions. When the thermosensitive metal unit expands and deforms towards the middle of the cable hole, the cutting unit will first pierce the rubber blocking pad and then cut off the cable.

[0022] Preferably, the protective ring is in a cylindrical structure, and the inner circle of the protective ring is adhesively fixed on the conductive core through glue. The conductive core in the reserved shearing section interval has the ability to be stretched.

[0023] Furthermore, a vacuum chamber is provided between the insulating outer skin and the conductive core. The vacuum chamber has the ability to insulate heat, so that the overall cable has a good effect of isolating the internal and external temperatures. And the vacuum chamber keeps a large gap between the insulating outer skin and the conductive core, so that the overall cable has enough clearance for buffering and avoiding when being compressed, preventing the cable from being damaged.

[0024] Preferably, the rubber ring is in a ring structure, the outer circle of the rubber ring is adhesively fixed on the inner wall of the insulating outer skin through glue, and the inner circle of the rubber ring is pressed and fitted on the outer circle of the protective ring by the internal structure of the rubber ring.

[0025] Specifically, the rubber ring isolates the adjacent vacuum chambers, so that when a certain position of the cable is cut off, the vacuum in the vacuum chambers at other positions will not be released, which is convenient for ensuring the normal use of the cable. When the cable is cut off and the cutting unit is pressed to the outer ring of the protective ring, it moves to the position of the reserved shearing section through the conical surfaces at both ends of the protective ring to cut off the conductive core, achieving the purpose of fixed-point cutting. When splicing and connecting the cable, directly repair the outside of the insulating sheath, and the broken position of the conductive core can be automatically repaired by attracting each other between the magnetic suction rings on the adjacent protective rings, achieving the purpose of convenient repair and replacing the need for winding the wire and then repairing the broken position in the prior art.

[0026] Preferably, both the wire management substrate and the wire management card board are in the shape of rectangular plates. The height of the wire management substrate is equal to half of the height of the wire management card board, and the heights of the wire management card boards spliced up and down are the same.

[0027] During operation, the conductive core at the position of the reserved shearing section is stretchable. When the whole cable is stretched, the two magnetic suction rings can also maintain a good attracting effect, so that the conductive cores at the broken position are automatically connected. When the whole cable is placed without movement, the conductive core can ensure the ability to stably transmit electricity. The suction force between the two magnetic suction rings is large, and the conductive core at the position of the reserved shearing section is stretchable. When the whole cable is pulled, the broken position of the conductive core can also maintain stable connection.

[0028] The technical effects and advantages of the present invention:

[0029] 1. For a wire and cable harness assembly with a wire management function of the present invention, an isolation component is arranged inside the wire management hole.

[0033] 5. For a wire and cable harness assembly with a combing function according to the present invention, when a cable on one side of the wire management card board catches fire, the high-temperature heat will be transferred to the thermosensitive metal unit in the middle of the wire management hole through the side of the cable and the wire management card board. When the thermosensitive metal unit is heated, it will expand and deform. Since the outer rigid outer support ring body of the thermosensitive metal unit cannot be elastically deformed, when the thermosensitive metal unit expands and deforms due to heat, it will squeeze towards the middle of the wire management hole. When the extrusion reaches the limit, the sides of multiple cutting units will fit together, and the tips of multiple cutting units will fit together, thereby cutting off the cable. Both the thermosensitive metal unit and the cutting unit are made of non-conductive and fire-blocking materials.

[0035] 7. For a wire and cable harness assembly with a combing function according to the present invention, when the thermosensitive metal unit elastically deforms, it can just elastically deform towards the inner circle of the wire management hole along the concave-shaped structure inside the rigid outer support ring body. A rubber blocking pad is provided to ensure that the cable is not cut by the cutting unit during normal use. When the thermosensitive metal unit expands and deforms towards the middle of the wire management hole, the cutting unit will first pierce the rubber blocking pad and then cut off the cable;

When splicing and connecting the cable, directly repair the outside of the insulating outer skin. The broken position of the conductive core can be automatically repaired by attracting each other between the magnetic suction rings on the adjacent protection rings, realizing the purpose of convenient repair, replacing the purpose of winding the wire and then repairing the broken position in the prior art;

[0038] 10. The conductive core at the position of the reserved shearing section has stretchability. When the whole cable is stretched, the two groups of magnetic suction rings can also maintain a good attracting effect, so that the conductive cores at the broken position are automatically connected.

And the suction force between the two groups of magnetic suction rings is large, and the conductive core at the position of the reserved shearing section has stretchability. When the whole cable is pulled, the broken position of the conductive core can also maintain stable connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The present invention provides a wire and cable harness assembly with a combing function as shown in Figures 1-10 , including a wire management substrate 1. Above the wire management substrate 1, there is a wire management card board 2. Between the wire management card board 2 and the wire management substrate 1, there is a wire management hole 3 for the cable 4 to pass through. The wire management hole 3 is arranged in a circular hole structure in multiple groups. On the front and rear sides of the bottom of the wire management substrate 1, there are lower fixing plates 5 fixedly arranged. On the lower fixing plates 5, there are reserved threaded holes 25. On both sides of the mutually approaching ends of the wire management substrate 1 and the wire management card board 2, there are side fixing plates 6 fixedly arranged. The two corresponding side fixing plates 6 are in movable contact with each other. Between the two corresponding side fixing plates 6, they are fixed by a connecting screw 24. The upper and lower ends of the connecting screw 24 are respectively connected with fixing nuts 26 through thread fitting. The two fixing nuts 26 are respectively in movable contact with the mutually remote ends of the two side fixing plates 6. Inside the wire management hole 3, there is a cleaning component for cleaning the surface of the cable 4 and an isolation component 7 for isolating the cable 4;

[0052] The isolation component 7 includes a first annular groove 10 disposed at the inner circle of the wire management hole 3. A rigid outer support ring body 13 is fixedly arranged on the inner wall of the first annular groove 10. A thermosensitive metal unit 11 is fixedly arranged on the inner wall of the rigid outer support ring body 13. A cutting unit 12 is fixedly arranged on the inner wall of the thermosensitive metal unit 11. The cutting unit 12 is arranged in a circular array, and multiple groups are equidistantly arranged around the inner wall of the thermosensitive metal unit 11. At the inner circle position of the multiple groups of cutting units 12, a rubber blocking pad 14 is fixed at the opening position where the first annular groove 10 communicates with the internal wire core assembly 8 inside. The thermosensitive metal unit 11, the rigid outer support ring body 13, and the cutting unit 12 are all arranged in the first annular groove 10. The surfaces of the wire management substrate 1 and the wire management clamping plate 2 facing each other are both in a semi-circular groove structure. The two semi-circular groove structures form the wire management hole 3. The rigid outer support ring body 13, the thermosensitive metal unit 11, and the rubber blocking pad 14 are all distributed in two semi-circular structures. The two rigid outer support ring bodies 13, the thermosensitive metal unit 11, and the rubber blocking pad 14 are respectively arranged in the two semi-circular groove structures;

[0053] The cable 4 includes an internal wire core assembly 8 in the inner layer and an insulating outer skin 9 covering the outside of the internal wire core assembly 8. The internal wire core assembly 8 includes a conductive core body 23 and a protective ring 15 sleeved outside the conductive core body 23. The protective ring 15 is fixedly sleeved outside the conductive core body 23, and multiple groups of the protective rings 15 are arranged at equal distances. Conical surfaces 16 are arranged at both ends of the protective ring 15. Magnetic suction rings 22 and rubber buffer rings 21 are fixedly arranged at both ends of the protective ring 15. The rubber buffer ring 21 is arranged on the side of the magnetic suction ring 22 away from the middle of the protective ring 15. A reserved shearing section 27 is formed between two adjacent groups of protective rings 15.

[0054] As Figures 1 to 6 shown, rubber rings 17 are movably attached to both ends of the protective ring 15. The rubber rings 17 are fixed on the inner wall of the insulating outer skin 9. A vacuum chamber 28 is formed between the inside of the insulating outer skin 9 and the outside of the conductive core body 23. The vacuum chamber 28 is divided into multiple groups by the rubber rings 17.

[0055] Furthermore, an isolation component 7 is arranged inside the wire management hole 3. When the isolation component 7 is heated, the position where the cable 4 passes through the wire management hole 3 can be cut off and isolated, avoiding the spread of fire from one side of the cable 4 on the wire management clamping plate 2 to the other side when a fire occurs on one side of the cable 4 on the wire management clamping plate 2. And the cleaning component can clean the surface of the cable 4 passing through the wire management hole 3. While the wire management clamping plate 2 serves the purpose of wire management for the cable 4, it can also clean the surface of the cable 4 and prevent the spread of fire.

[0056] Reference Figure 7As shown in the figure, the cleaning component includes a second annular groove 18 provided on the inner wall of the wire management hole 3. A support spring 19 is fixedly welded to the bottom of the second annular groove 18. The end of the support spring 19 is fixedly provided with a wiping cotton ring 20. The wiping cotton ring 20 is movably arranged in the second annular groove 18, and the inner ring of the wiping cotton ring 20 is movably attached to the outer ring of the insulating outer skin 9.

[0057] Among them, when the cable 4 passes through the position of the wire management hole 3, the support spring 19 abuts against the wiping cotton ring 20 to fit against the outer ring of the insulating outer skin 9, thereby cleaning the surface of the cable 4 passing through the position of the wire management hole 3. And the support spring 19 abuts against the wiping cotton ring 20 to ensure that the wiping cotton ring 20 is always attached to the outer ring of the insulating outer skin 9, achieving the purpose of facilitating the cleaning of the cable 4.

[0058] As Figure 5 shown in the figure, a set of the second annular groove 18 is provided on each side of the first annular groove 10. The first annular groove 10 is arranged in the middle position of the wire management hole 3. The wiping cotton ring 20 includes two sets of semi-circular wiping cotton strips, and the heads and tails of the two sets of wiping cotton strips are mutually attached.

[0059] In the device, a set of the second annular groove 18 is provided on each side of the first annular groove 10, which is convenient for double cleaning of the cables 4 entering and exiting from both sides of the wire management hole 3, and has good cleanliness. And the wiping cotton ring 20 includes two sets of semi-circular wiping cotton strips. The semi-circular wiping cotton strips are convenient for individual replacement and maintenance when disassembling and assembling the wire management base plate 1 and the wire management card plate 2, without affecting the removal of the cable 4 from the wire management hole 3.

[0060] Refer to Figure 3 and Figure 4 shown in the figure, several sets of wire management card plates 2 are spliced above the wire management card plate 2 above the wire management base plate 1. The adjacent wire management card plates 2 form a wire management hole 3 for the cable 4 to pass through movably. Side fixing plates 6 are also fixedly welded to the upper ends of both sides of the wire management card plate 2. When the adjacent wire management card plates 2 are spliced with each other, they are fixed by the connecting screws 24 on the two side fixing plates 6.

[0061] Specifically, multiple sets of wire management card plates 2 can be spliced according to the number of cables 4. When the multiple sets of wire management card plates 2 are spliced with each other, they are fixed by the side fixing plates 6 and the connecting screws 24 on the side fixing plates 6, which is convenient for connection. Generally, three sets of wire management holes 3 are provided between the wire management base plate 1 and the wire management card plate 2. When the total number of cables 4 exceeds three sets, several sets of wire management card plates 2 can be spliced above the wire management card plate 2 above the wire management base plate 1, which is convenient for splicing and using according to the number of cables 4. And the wire management base plate 1 is integrally fixed to the bottom structure through the lower fixing plate 5. The screw can pass through the reserved threaded hole 25, which is convenient for fixing.

[0062] As Figure 8 and Figure 10As shown, the cutting unit 12 has a triangular tooth-like structure. The cutting units 12 are spaced along the thermosensitive metal unit 11. The gap between adjacent cutting units 12 is for the thermosensitive metal unit 11 to expand and contract, squeezing the adjacent cutting units 12 to move when they fit together. When multiple groups of cutting units 12 fit together, the tips of multiple groups of cutting units 12 also fit together.

[0063] It should be noted that when the cable 4 on one side of the cable management card board 2 catches fire, the high-temperature heat will be transferred to the thermosensitive metal unit 11 in the middle of the cable management hole 3 through the cable 4 and the side of the cable management card board 2. When the thermosensitive metal unit 11 is heated, it will expand and deform. Since the outer rigid outer support ring body 13 of the thermosensitive metal unit 11 cannot be elastically deformed, when the thermosensitive metal unit 11 expands and deforms due to heat, it will squeeze towards the middle of the cable management hole 3. When the extrusion reaches the limit, the sides of multiple groups of cutting units 12 fit together, and the tips of multiple groups of cutting units 12 fit together, thus cutting off the cable 4. Both the thermosensitive metal unit 11 and the cutting unit 12 are made of non-conductive and fire-blocking materials. Therefore, it plays a role in cutting off the cable 4 to avoid the spread of fire and power transmission. In the above, the cutting unit 12 can use ceramic materials, and the thermosensitive metal unit 11 can use insulating thermosensitive materials, etc.;

[0064] When preventing the spread of fire, it is necessary to ensure the normal transmission of electricity. The cutting unit 12 and the thermosensitive metal unit 11 can both use conductive metal materials, etc. This will not be elaborated here, and specific materials can be selected according to actual needs, achieving the purpose of separately preventing the spread of fire, and the structural design is reasonable.

[0065] Reference Figure 8 As shown, the cross-section of the rigid outer support ring body 13 has a concave structure. The thermosensitive metal unit 11 is fixed at the bottom of the concave structure of the rigid outer support ring body 13. The thickness of the thermosensitive metal unit 11 is the same as the width of the inner concave shape of the rigid outer support ring body 13. The cutting unit 12 on the surface of the thermosensitive metal unit 11 fits on the outer circle of the rubber blocking pad 14.

[0066] During operation, when the thermosensitive metal unit 11 elastically deforms, it can just elastically deform along the inner concave structure of the rigid outer support ring body 13 towards the inner circle of the cable management hole 3. The rubber blocking pad 14 is provided to ensure that the cable 4 is not cut by the cutting unit 12 during normal use. When the thermosensitive metal unit 11 expands and deforms towards the middle of the cable management hole 3, the cutting unit 12 will first pierce the rubber blocking pad 14 and then cut off the cable 4.

[0067] As Figure 9 As shown, the protective ring 15 has a cylindrical structure. The inner circle of the protective ring 15 is adhesively fixed on the conductive core 23 through glue. The conductive core 23 in the reserved shearing section 27 has the ability to be stretched.

[0068] Furthermore, a vacuum chamber 28 is provided between the insulating outer sheath 9 and the conductive core 23. The vacuum chamber 28 has the ability to insulate heat, enabling the overall cable 4 to have a good effect of isolating the internal and external temperatures. The vacuum chamber 28 keeps a large gap between the insulating outer sheath 9 and the conductive core 23, so that when the overall cable 4 is compressed, there is enough clearance for buffering and avoidance, preventing the cable 4 from being crushed.

[0069] As Figure 9 shown in, the rubber ring 17 has an annular structure. The outer ring of the rubber ring 17 is adhesively fixed to the inner wall of the insulating outer sheath 9 by glue, and the inner ring of the rubber ring 17 is pressed and fitted to the outer ring of the protective ring 15 by the internal structure of the rubber ring 17.

[0070] Specifically, the rubber ring 17 separates the adjacent vacuum chambers 28, so that when a certain position of the cable 4 is cut off, the vacuum in the vacuum chambers 28 at other positions will not be released, which is convenient for ensuring the normal use of the cable 4. When the cable 4 is cut off, when the cutting unit 12 is pressed against the outer ring of the protective ring 15, it moves to the position of the reserved shearing section 27 through the conical surfaces 16 at both ends of the protective ring 15 to cut off the conductive core 23, achieving the purpose of fixed-point cutting. When it is necessary to splice and connect the cable 4, the outer part of the insulating outer sheath 9 is directly repaired. The broken position of the conductive core 23 can be automatically repaired by attracting each other between the magnetic suction rings 22 on the adjacent protective rings 15, realizing the purpose of convenient repair, replacing the need to wind the wire and then repair the broken position in the prior art.

[0071] As Figure 1 、 Figure 2 and Figure 9 shown in, the wire management base plate 1 and the wire management card plate 2 both have a rectangular plate structure. The height of the wire management base plate 1 is equal to half of the height of the wire management card plate 2, and the heights of the spliced wire management card plates 2 are the same.

[0072] During operation, the conductive core 23 at the position of the reserved shearing section 27 has stretchability. When the overall cable 4 is stretched, the two magnetic suction rings 22 can also maintain a good attracting effect, enabling the automatic connection of the broken conductive core 23. When the overall cable 4 is placed without movement, the conductive core 23 can ensure the ability to stably transmit electricity. The suction force between the two magnetic suction rings 22 is large, and the conductive core 23 at the position of the reserved shearing section 27 has stretchability. When the overall cable 4 is pulled, the broken position of the conductive core 23 can also maintain a stable connection.

[0073] Working principle: An isolation component 7 is arranged inside the wire management hole 3. When the isolation component 7 is heated, it can cut off and isolate the position where the cable 4 passes through the wire management hole 3, preventing the spread of fire from one side of the cable 4 on the wire management card board 2 to the other side of the wire management card board 2. The cleaning component can clean the surface of the cable 4 passing through the wire management hole 3. While the wire management card board 2 serves the purpose of wire management for the cable 4, it can also clean the surface of the cable 4 and prevent the spread of fire.

[0074] When the cable 4 passes through the position of the wire management hole 3, the support spring 19 abuts against the wiping cotton ring 20 to fit around the outer circle of the insulating outer sheath 9, thereby cleaning the surface of the cable 4 passing through the position of the wire management hole 3. The support spring 19 abutting against the wiping cotton ring 20 can ensure that the wiping cotton ring 20 is always fitted around the outer circle of the insulating outer sheath 9, achieving the purpose of conveniently cleaning the cable 4.

[0075] A set of second annular grooves 18 is arranged on each side of the first annular groove 10, facilitating double cleaning of the cables 4 entering and exiting from both sides of the wire management hole 3, with good cleanliness. The wiping cotton ring 20 includes two semi-circular wiping cotton strips. The semi-circular wiping cotton strips are convenient for individual replacement and maintenance when disassembling and assembling the wire management base plate 1 and the wire management card board 2, without affecting the removal of the cable 4 from the wire management hole 3.

[0076] Multiple groups of wire management card boards 2 can be spliced according to the number of cables 4. When multiple groups of wire management card boards 2 are spliced together, they are fixed through the side fixing plates 6 and the connecting screws 24 on the side fixing plates 6, which is convenient for connection. Generally, three wire management holes 3 are arranged between the wire management base plate 1 and the wire management card board 2. When the total number of cables 4 exceeds three groups, several groups of wire management card boards 2 can be spliced above the wire management card board 2 above the wire management base plate 1, facilitating splicing and use according to the number of cables 4. The wire management base plate 1 is integrally fixed to the bottom structure through the lower fixing plate 5, and the screws can pass through the reserved threaded holes 25, which is convenient for fixing.

[0077] When the cable 4 on one side of the wire management card board 2 catches fire, the high-temperature heat will be transmitted to the thermosensitive metal unit 11 in the middle of the wire management hole 3 through the side of the cable 4 and the wire management card board 2. When the thermosensitive metal unit 11 is heated, it will expand and deform. Since the outer rigid outer support ring body 13 of the thermosensitive metal unit 11 cannot be elastically deformed, when the thermosensitive metal unit 11 expands and deforms due to heat, it squeezes towards the middle of the wire management hole 3. When the extrusion reaches the limit, the sides of multiple cutting units 12 fit together, and the tips of multiple cutting units 12 fit together, thereby cutting off the cable 4. Both the thermosensitive metal unit 11 and the cutting unit 12 are made of materials that do not conduct electricity and prevent the spread of fire. Therefore, it plays a role in cutting off the cable 4 to avoid the spread of fire and power transmission. In the above, the cutting unit 12 can use ceramic materials, and the thermosensitive metal unit 11 can use insulating thermosensitive materials, etc.;

[0078] When preventing the spread of fire, it is necessary to ensure the normal transmission of electricity. The cutting unit 12 and the thermosensitive metal unit 11 can both use conductive metal materials, etc., which will not be elaborated here and can be selected according to actual needs. The purpose of separately preventing the spread of fire is achieved, and the structural design is reasonable.

[0079] When the thermosensitive metal unit 11 elastically deforms, it can just elastically deform along the concave-shaped structure inside the rigid outer support ring 13 towards the inner circle of the wire management hole 3. The rubber blocking pad 14 is provided to ensure that the cable 4 is not cut by the cutting unit 12 under normal use conditions. When the thermosensitive metal unit 11 expands and deforms towards the middle of the wire management hole 3, the cutting unit 12 will first pierce the rubber blocking pad 14 and then cut off the cable 4.

[0080] A vacuum chamber 28 is provided between the insulating outer skin 9 and the conductive core 23. The vacuum chamber 28 has the ability to insulate heat, enabling the overall cable 4 to have a good effect of isolating the internal and external temperatures. And the vacuum chamber 28 keeps a large gap between the insulating outer skin 9 and the conductive core 23, enabling the overall cable 4 to have sufficient clearance for buffering and avoidance when being pressed, avoiding the cable 4 from being damaged.

[0081] The rubber ring 17 separates the adjacent vacuum chambers 28, so that when a certain position of the cable 4 is cut off, the vacuum in the vacuum chambers 28 at other positions will not be released, which is convenient for ensuring the normal use of the cable 4. When the cable 4 is cut off and the cutting unit 12 is squeezed to the outer circle of the protection ring 15, it moves to the position of the reserved shear section 27 through the conical surfaces 16 at both ends of the protection ring 15 to cut off the conductive core 23, achieving the purpose of fixed-point cutting. When it is necessary to splice and connect the cable 4, the outside of the insulating outer skin 9 is directly repaired, and the broken position of the conductive core 23 can be automatically repaired by attracting each other between the magnetic suction rings 22 on the adjacent protection rings 15, achieving the purpose of convenient repair and replacing the need to wind the wire and then repair the broken position in the prior art.

[0082] The conductive core 23 at the position of the reserved shear section 27 has stretchability. When the overall cable 4 is stretched, the two groups of magnetic suction rings 22 can also maintain a good attracting effect, enabling the conductive core 23 at the broken position to be automatically connected. When the overall cable 4 is placed without movement, the conductive core 23 can ensure the ability to stably transmit electricity. And the suction force between the two groups of magnetic suction rings 22 is large, and the conductive core 23 at the position of the reserved shear section 27 has stretchability. When the overall cable 4 is pulled, the broken position of the conductive core 23 can also maintain a stable connection.
