[0061] A heat dissipation fan 35 is installed in the middle of the receiving slot 31, and the heat dissipation fan 35 is placed on the top of each first heat conducting sheet 32;

[0063] The upper heat conducting member 5 is installed at the inner top of the receiving groove 31. The upper heat conducting member 5 includes a transverse heat conducting plate 51 and a second heat conducting plate 52. The transverse heat conducting plate 51 is horizontally slidably placed at the inner top of the receiving groove 31. A plurality of groups of second heat conducting plates 52 are vertically arranged on the top surface of the transverse heat conducting plate 51. Each group of second heat conducting plates 52 is relatively vertically slidable and penetrates a through hole 411.

[0064] The transfer connector 6 has one end inserted into the reserved socket 34 and the other end sealedly inserted into the end opening of the spiral heat dissipation channel; the heat in the spiral heat dissipation channel is conducted to the receiving groove 31 through the transfer connector 6;

[0065] A plurality of temperature probes are provided, and the temperature probes are installed in the receiving groove 31 and on the outer wall of the wear-resistant protection belt;

[0066] The wiring harness includes the following heat dissipation modes:

[0067] The first mode: the temperature of the wire harness is low, the movable cover 4 seals the receiving groove 31, the heat dissipation fan 35 does not work, the end of the transfer connector 6 is open, and the heat in the receiving groove 31 is discharged through the second heat conducting sheet 52;

[0068] Second mode: when the temperature of the contact terminal 3 is high, the transverse heat conducting plate 51 moves horizontally once to lift up the movable cover 4, so that the ventilation hole 421 is exposed, and the end of the transverse heat conducting plate 51 blocks the end of the transfer connector 6; the heat dissipation fan 35 works to quickly extract the heat of the receiving slot 31 from the ventilation hole;

[0069] The third mode: the temperature of the spiral heat dissipation channel is high, the transverse heat conduction plate 51 is transversely moved a second time to open the end of the transfer joint 6, and the movable cover 4 remains open; the heat dissipation fan 35 works to quickly extract the heat of the receiving groove 31 and the spiral heating channel from the vent.

[0070] In the above scheme:

[0071] 1. The setting of wear-resistant protective belt can achieve the following effects:

[0072] 1.1. It can protect the outside of the main cable to prevent corrosion and wear of the main cable;

[0073] 1.2. It can form a spiral heat dissipation channel with the main cable, so that the heat generated by the main cable can be discharged through the spiral heat dissipation channel, avoiding heat accumulation in the wear-resistant protective belt, eliminating the risk of spontaneous combustion, and allowing the wire harness to take into account both wear-resistant protection and air-conducting heat dissipation;

[0074] 2. A receiving groove is provided in the contact terminal, and a first heat conducting sheet is provided in the groove. The first heat conducting sheet can conduct the working heat inside the contact terminal to the receiving groove to achieve heat dissipation of the contact terminal; an exhaust fan is provided in the receiving groove to speed up the heat dissipation;

[0075] 3. The transfer joint can connect the spiral heat dissipation channel with the receiving groove to achieve sealed connection, preventing dust from entering from the end of the spiral heat dissipation channel. The heat of the spiral heat dissipation channel can enter the receiving groove and then be discharged, which can meet the needs of heat dissipation;

[0076] 4. The movable cover can close the receiving slot when the temperature of the wire harness is normal, so that the heat in the receiving slot is discharged through the horizontal heat conducting plate and the second heat conducting plate, so as to achieve sealed heat dissipation and prevent external dust from entering the receiving slot or the spiral heat dissipation channel; when the temperature of the wire harness is high, the movable cover is lifted to expose the ventilation hole, so that the heat dissipation fan can quickly discharge the heat in the receiving slot from the ventilation hole to reduce the heat in the fast receiving slot, thereby reducing the temperature of the contact terminal and the main cable;

[0077] 5. Setting a transverse heat conduction plate that can be moved laterally can achieve the following effects:

[0078] 5.1. The horizontal heat conducting plate can speed up the heat dissipation of the second heat conducting plate;

[0079] 5.2. In mode 1, the horizontal heat conducting plate is retracted to one side, so that the movable cover can seal the receiving groove and the end of the transfer joint can be exposed, so that the heat of the transfer joint can be fully dissipated into the receiving groove;

[0080] 5.2. In the second mode, the transverse heat conduction plate moves horizontally once, and the horizontal movement can achieve the following effects:

[0081] The horizontal heat conducting plate can be lifted up and the movable cover can be opened to allow the ventilation holes to leak out, and the movable cover does not need to be controlled separately;

[0082] The horizontal heat conduction plate can be inserted into the sealing transfer joint to prevent external dust from entering the transfer joint when the ventilation hole is exposed;

[0083] When the horizontal heat conducting plate is inserted into the blocking transfer joint, the heat conducting length can be extended. When the heat dissipation fan exhausts the heat from the horizontal heat conducting plate, it can also export the heat in the spiral heat dissipation channel, thus ensuring the heat dissipation effect and avoiding rapid temperature rise in the spiral heat dissipation channel.

[0084] 5.3. In mode three, the horizontal heat conduction plate is designed to continue to move horizontally, so that the movable cover can be kept open and the end of the transfer joint can be opened. In this way, when the cooling fan exhausts air, the heat in the transfer joint and the spiral heat dissipation channel can be quickly taken out, which can quickly reduce the temperature of the receiving slot and the main cable.

[0085] In order to enable the movable cover to cooperate with the transverse heat conducting plate to conduct heat, the following design of the movable cover is given:

[0086] In the present embodiment, the movable cover 4 comprises an upper plate body 41, a middle cover body 42, a lower plate body 43, and a matching bevel block 44. The upper plate body 41 is elastically sealed at the top of the accommodating groove 31. A through hole 411 is provided on the surface of the upper plate body 41. The area of ​​the middle cover body 42 is not larger than the area of ​​the upper plate body 41. The side section of the middle cover body 42 is stepped. Ventilation holes 421 are provided on the four sides of the middle cover body 42. The lower plate body 43 is vertically slidably embedded in the accommodating groove 31. An air guide hole 421 is provided in the middle of the lower plate body 43. Matching bevel blocks 44 are provided at both ends of the bottom surface of the lower plate body 43. The matching bevel block 44 is a right-angled trapezoidal structure that is wide at the top and narrow at the bottom. The bevel of the matching bevel block 44 is arranged toward the side away from the transfer joint 6. The cross-section of one end of the movable cover is Z-shaped.

[0087] In the above scheme:

[0088] 1. Spring rods are provided at both ends of the upper plate body, which are embedded in the contact terminals. The upper plate body can seal the receiving groove to prevent dust from falling in;

[0089] 2. The cover body is designed to be an inward-retracting structure, so that when the movable cover is extended, the upper plate can enclose and protect the ventilation holes to prevent external impurities from falling directly into the ventilation holes;

[0090] 3. The lower plate can be fixedly matched with the inclined block, and the air guide holes can guide the hot air upward to the ventilation holes; when the inclined block is subjected to force, the upper plate can be driven to lift and expose, and at the same time, the bottom plane of the inclined block can also ensure secondary lateral contact.

[0091] The movable cover only moves vertically, while the transverse heat conducting plate and the second heat conducting sheet move horizontally. In order to make the second heat conducting sheet meet the working requirements of each mode, this embodiment provides the following solution:

[0092] In this embodiment, flexible sealing belts 521 are symmetrically provided on both sides of the top of the second heat conductive sheet 52, and the outer ends of the flexible sealing belts 521 are fixedly connected to the inner wall of the through hole 411; in the first mode, the flexible sealing belt 521 does not deform and seals the through hole 411; in the second mode and the third mode, the flexible sealing belt 521 moves horizontally and vertically with the second heat conductive sheet 52, and leaves the through hole 411 open for heat dissipation.

[0093] In the above scheme, in mode 1, the flexible sealing belt does not deform, and the flexible sealing belt is placed in the perforation to seal the perforation to prevent external impurities from falling into the receiving groove; in mode 2 and mode 3, the second heat conducting plate and the movable cover are both in motion, and when the upper plate moves upward, the flexible sealing belt is relatively stretched downward, and at the same time, the second heat conducting plate also stretches the flexible sealing belt laterally, so that the flexible sealing belt can bring the following effects:

[0094] 1. It does not affect the displacement of the second heat conducting sheet and the upper plate, and at the same time makes the perforations exposed;

[0095] 2. Heat can be discharged not only through the ventilation holes, but also from the side holes, thereby helping to increase the heat dissipation speed;

[0096] 3. The flexible sealing belt is deformed downward to the bottom of the lower plate, which can intercept impurities to a certain extent and prevent them from falling directly into the plate.

[0097] In this embodiment, the transverse heat conducting plate 51 is a rectangular sheet structure, a rectangular hole 511 is opened in the middle of the transverse heat conducting plate 51, a sealing block 55 is provided at one end of the transverse heat conducting plate 51, and the sealing block 55 and the transverse heat conducting plate 51 are distributed in a T shape.

[0098] In the above scheme: the horizontal heat conduction plate adopts a rectangular sheet structure with a large heat conduction area and good heat conduction effect. The setting of rectangular holes can increase the air contact amount and accelerate the cooling speed of the horizontal heat conduction plate. The T-shaped structure is designed to meet the needs of one-time insertion of the sealing block for sealing and secondary insertion for air leakage.

[0099] In this embodiment, the top surface of the transverse heat conducting plate 51 is symmetrically provided with a resisting inclined block 53, and each group of matching inclined blocks corresponds to a group of resisting inclined blocks 53; the side of the transverse heat conducting plate 51 is provided with a driving screw 54 for driving the transverse heat conducting plate 51 to move horizontally, and the bottom surface of the transverse heat conducting plate is slidably connected to the supporting guide rail 56, and the supporting guide rail is vertically arranged in the accommodating groove; in the first mode, the resisting inclined block 53 is located on one side of the matching inclined block; in the second mode, the resisting inclined block 53 moves horizontally once, and the resisting inclined block 53 resists the matching inclined block, so that the sealing cover is lifted up and opened; in the third mode, the resisting inclined block 53 moves horizontally for the second time, and the resisting inclined block 53 moves horizontally along the bottom surface of the matching inclined block, so that the sealing cover remains open.

[0100] In the above scheme: two groups of side blocks are provided on the side of the horizontal heat conduction plate, and the driving screw passes through the two groups of side blocks. When the driving screw rotates, the horizontal heat conduction plate is driven to move along the supporting guide rail to realize the translation of the horizontal heat conduction plate. During the translation, the abutting inclined block abuts against the matching inclined block, so that the upper plate is lifted up and exposed.

[0101] In this embodiment, the transfer joint 6 includes a rectangular insert 61, an air guide hose 62 and a docking tube 63. The back of the rectangular insert 61 is connected to the docking tube 63 through the air guide hose 62, and the docking tube 63 is sealed and inserted into the end of the spiral heat dissipation channel; the rectangular insert 61 is inserted into the reserved socket 34, and the docking end of the rectangular insert 61 is embedded with a docking frame 611. The inner diameter of the docking frame is smaller than the inner diameter of the rectangular insert 61, and the cross-sectional area of ​​the blocking block 55 is the same as the internal opening cross-sectional area of ​​the docking frame; in the first mode, the blocking block 55 is away from the rectangular insert 61; in the second mode, the blocking block 55 is embedded in the docking frame; in the third mode, the blocking block 55 extends into the rectangular insert 61.

[0102] In the above scheme: during the first transverse movement, the blocking block is embedded in the docking frame of the rectangular insert, so that the rectangular insert can be blocked to achieve blocking, which can both conduct heat and prevent dust from entering; during the second transverse movement, the blocking block passes over the docking frame and enters the rectangular insert, and the transverse heat conduction plate enters the docking frame, so that a gap can be left in the docking frame to achieve convection conduction;

[0103] When the blocking block enters, it not only allows the air flow to flow, but also allows the heat in the rectangular plug-in and the spiral heat dissipation channel to be brought out when the cooling fan exhausts air, effectively reducing the temperature of the main cable. At the same time, some of the dust that enters can be intercepted by the blocking block in the rectangular plug-in, thereby preventing dust from entering the spiral heat dissipation channel to the greatest extent.

[0104] In this embodiment, the wear-resistant protective belt 2 includes a semicircular cover 21, a side belt body 211, an inner convex strip 22, and a thermal conductive strip 23.

The thermal conductive strip 23 is embedded in the spiral groove 11, and the adjacent side belt bodies 211 are bonded as a whole; the head of the docking tube 63 is connected and inserted into the internal cavity of the semicircular cover 21.

[0105] In the above scheme:

The side belt body can be used as a connecting structure of the semicircular cover, and the overlapping parts of adjacent side belt bodies are bonded together;

[0107] The heat-conducting strip can be embedded in the spiral groove to increase the heat-conducting effect; the inner convex strip can be used as a connection and positioning structure for the heat-conducting strip, so that the heat-conducting strip can be fixed in the semicircular cover.

[0108] In this embodiment, the inner convex strip 22 includes an inner cover body 221 and a connecting strip 222. The side cross-section of the inner cover body 221 is semicircular. The inner cover body 2211 is arranged inside the semicircular cover 21. The interior of the inner cover body 221 is filled with a desiccant 223.

An arc groove 231 is provided on the thermal conductive strip 23, and the connecting strip 222 is glued into the arc groove 231 of the thermal conductive strip 23.

[0120] The design of the ball ensures that the lifting component can move with the outer ring body. When moving, the ball can also roll on the connection of the wear-resistant protective belt to enhance the connection effect.

[0121] The ball bearing is designed to have an elastic structure so that it can avoid the semi-circular cover and will not cause the semi-circular cover to be squeezed and deformed.
