The high-voltage wire harness plays a key role in the new energy vehicle. It can connect various components on the high-voltage system and serve as a medium for transmitting the high-voltage power supply. It is the main carrier of power output on an electric vehicle. At the same time, the high-voltage wire harness also needs to meet a series of performance requirements, such as electrical performance, mechanical performance, and environmental performance, etc., to ensure its stable operation in complex environments such as high current and high voltage.

[0003] In the prior art, new energy vehicles mainly rely on electric drive, and the high-voltage wire harness for transmitting electric energy is similar to the blood vessels of a new energy vehicle. Since electric energy inevitably generates losses during use by the user, the lost electric energy is likely to generate heat at the connection point, that is, the interface position. Thus, the high temperature will affect the transmission efficiency of the joint and even further increase the losses. Moreover, the bumps generated during the vehicle's driving will cause the interface to become loose, and the entry of dust and moisture will further affect the stable and safe use of the device. Therefore, a connection device and a connection method for a high-voltage wire harness of a new energy vehicle are needed to meet people's needs. Summary of the Invention

Two L-shaped movable clamping plates adapted to the shape of the connection plug are used to sleeve the connection part of the connection socket and the connection plug, thereby avoiding the loosening of the connection between the connection socket and the connection plug due to factors such as bumps. At the same time, positioning blocks are used to fix the heat dissipation components, avoiding the accidental touch of the heat dissipation components and affecting the stability of the L-shaped movable clamping plate, ensuring the stable connection between the connection socket and the connection plug, and avoiding the intrusion of dust and moisture.

[0025] In an alternative embodiment: Wire harness fitting grooves 203 are opened at the ends of the L-shaped movable clamping plates 202 close to each other. Both of the two wire harness fitting grooves 203 are in line contact with the high-voltage wire harness 103. Two limit sliding holes 204 are opened on the L-shaped movable clamping plate 202. Limit sliding rods 205 are slidably installed in both of the two limit sliding holes 204. Both of the two limit sliding rods 205 are fixedly installed on the connection socket 100.

[0026] It should be noted that the movable L-shaped movable clamping plate 202 is restricted by the wire harness fitting grooves 203 and the limit sliding holes 204 and can only move within a fixed range.

[0027] In an alternative embodiment: Driving holes 206 are opened at both ends of the driving rod 201. Driving shafts 207 are rotatably installed in both of the two driving holes 206.

[0028] It should be noted that when the connection plug 102 is inserted into the connection slot 104 of the connection socket 100, the L-shaped movable plate 200 will drive the positioning slide bar 210 to slide in the positioning slide hole 209 of the fixed plate 208 while moving, so that the L-shaped movable plate 200 is restricted by the fixed plate 208 and can only move within a fixed range.

[0030] It should be noted that since the L-shaped movable plate 200 compresses the return spring 211 when sliding, after releasing the L-shaped movable plate 200, the return spring 211 can push the L-shaped movable plate 200 back to its original position, and then the two L-shaped movable clamping plates 202 return to their original positions to cover the connection plug 102, thereby protecting the connection socket 100 and the connection plug 102 and preventing the connection plug 102 from accidentally falling off the connection socket 100.

[0031] In an optional embodiment: the heat dissipation component 300 includes a heat dissipation box 301. The heat dissipation box 301 is fixedly installed on the controller 101. A heat dissipation channel 302 is formed on the heat dissipation box 301. A coolant heat pump 304 is fixedly installed in the heat dissipation box 301.

A high-speed heat dissipation fan 303 and a dust filter net 307 are fixedly installed on the inner wall of the heat dissipation channel 302.

[0032] It should be noted that inside the heat dissipation box 301, the heat dissipation channel 302 is used to generate an air flow to blow on the heat dissipation fins 306 installed on the coolant heat dissipation pipe 305, and the high-speed flowing air is used to cool the coolant, so as to ensure that the coolant can assist in cooling the connection socket 100 for a long time. The dust filter net 307 can filter the dust in the air to prevent the dust from accumulating on the heat dissipation fins 306 and affecting its heat dissipation effect.

[0033] In an optional embodiment: a coolant input pipe 400 and a coolant output pipe 401 are respectively fixedly installed on the top side and the bottom side of the connection socket 100. The coolant input pipe 400 and the coolant output pipe 401 are respectively connected to the coolant heat pump 304 and the coolant heat dissipation pipe 305. A coolant collecting pipe 402 and a coolant dividing pipe 404 are fixedly installed in the connection socket 100. A plurality of coolant pipes 403 are fixedly installed between the coolant collecting pipe 402 and the coolant dividing pipe 404.

[0034] It should be noted that when the temperature sensor 600 detects an increase in the temperature of the connection socket 100, in order to ensure the safe use of the connection socket 100 and the connection plug 102, the coolant cooling pump 304 is started, so that the coolant circulates in the order of the coolant input pipe 400, the coolant cooling pipe 305, the coolant output pipe 401, the coolant diversion pipe 404, the coolant pipe 403, and the coolant collection pipe 402, and the accumulated heat on the housing of the connection socket 100 is taken away by the flowing coolant.

[0035] In an alternative embodiment: The fire protection component 500 includes a fire protection box 501. An installation pad 502 is fixedly installed in the fire protection box 501.

An electronic control valve 506 is fixedly installed on the fire protection pipe 504. Two installation hoop sleeves 507 are placed on the carbon dioxide fire extinguisher 503. Installation bolts 508 are threadedly installed at the contact part between the installation hoop sleeve 507 and the carbon dioxide fire extinguisher 503.

[0036] It should be noted that when the temperature sensor 600 detects that the temperature of the connection socket 100 has an abnormal increase and poses a safety hazard, the electronic control valve 506 is started, so that the carbon dioxide fire extinguisher 503 compresses carbon dioxide and sprays it on the connection socket 100 and the connection plug 102 through the fire protection nozzle 505 to extinguish the fire hazard in the first time. The carbon dioxide fire extinguisher 503 is fixed in the fire protection component 500 by using the installation hoop sleeve 507 and the installation bolt 508, which facilitates the replacement and maintenance of the carbon dioxide fire extinguisher 503.

[0037] In an alternative embodiment: A positioning block 700 is rotatably installed on the L-shaped movable plate 200. A positioning hole 701 is opened on the positioning block 700. A positioning pin 702 is inserted into the positioning hole 701. The positioning pin 702 is fixedly installed on the connection socket 100. A connection hole 703 is opened on the positioning block 700. A connection shaft 704 is rotatably installed in the connection hole 703. The connection shaft 704 is fixedly installed on the L-shaped movable plate 200. The positioning hole 701 on the positioning block 700 is connected to the positioning pin 702 to complete the fixation of the position of the L-shaped movable plate 200, avoiding accidental touch of the L-shaped movable plate 200 or the movement of the L-shaped movable plate 200 caused by bumps, which affects the connection stability between the device and the connection socket 100 and the connection plug 102.

[0038] A connection method for a high-voltage wire harness of a new energy vehicle is specifically as follows: Step 1: First, move the L-shaped movable plate 200, so that the L-shaped movable plate 200 drives the L-shaped movable clamping plate 202 to slide on the limit sliding hole 204 through the driving rod 201, thereby exposing the connection part of the connection socket 100.

[0039] Step 2: It is necessary to clean the interface parts of the connection socket 100 and the connection plug 102, and make the connection sleeve 105 and the connection head 106 correspond to each other.

[0040] Step 3: Plug the connection plug 102 into the connection socket 100, release the L-shaped movable plate 200, and the compressed return spring 211 will drive the L-shaped movable plate 200 back to its original position, thereby reassembling the L-shaped movable clamping plate 202 together to ensure that the connection socket 100 and the connection plug 102 are stably connected together.

[0041] Step 4: To prevent the accidental movement of the L-shaped movable plate 200, use the positioning block 700 to fix the position of the L-shaped movable plate 200 to prevent the L-shaped movable clamping plate 202 from separating due to accidental contact with the L-shaped movable plate 200.

[0042] The working principle of the present invention: When using this device, first, it is necessary to connect the connection socket 100 and the connection plug 102. Adjust the position of the movable L-shaped movable plate 200 so that the L-shaped movable plate 200 drives the driving rod 201 to rotate through the driving hole 206 and the driving shaft 207. The rotating driving rod 201 drives the L-shaped movable clamping plate 202 to move through another pair of driving holes 206 and driving shafts 207, causing the two L-shaped movable clamping plates 202 to move away from each other. The movable L-shaped movable clamping plate 202 is restricted by the wire harness fitting groove 203 and the limiting sliding hole 204 and can only move within a fixed range. At this time, insert the connection plug 102 into the connection slot 104 on the connection socket 100. When the L-shaped movable plate 200 moves, it will drive the positioning slide rod 210 to slide in the positioning slide hole 209 on the fixed plate 208, so that the L-shaped movable plate 200 is restricted by the fixed plate 208 and can only move within a fixed range. Since the L-shaped movable plate 200 will compress the return spring 211 when sliding, after releasing the L-shaped movable plate 200, the return spring 211 can push the L-shaped movable plate 200 back to its original position, and then the two L-shaped movable clamping plates 202 return to their original positions, covering the connection plug 102, thereby protecting the connection socket 100 and the connection plug 102 and preventing the connection plug 102 from accidentally falling off the connection socket 100. The wire harness fitting groove 203 on the L-shaped movable clamping plate 202 is adapted to the high-voltage wire harness 103. When the L-shaped movable clamping plate 202 is reset, connect the positioning hole 701 on the positioning block 700 to the positioning pin 702 to fix the position of the L-shaped movable plate 200, avoiding accidental contact with the L-shaped movable plate 200 or the L-shaped movable plate 200 moving due to jolting, which affects the connection stability between the device and the connection socket 100 and the connection plug 102; When the temperature sensor 600 detects that the temperature of the connection socket 100 rises, to ensure the safe use of the connection socket 100 and the connection plug 102, start the coolant cooling pump 304, so that the coolant circulates in the order of the coolant input pipe 400, the coolant cooling pipe 305, the coolant output pipe 401, the coolant diversion pipe 404, the coolant pipe 403, and the coolant collection pipe 402. Use the flowing coolant to take away the accumulated heat on the housing of the connection socket 100. Thus, inside the heat dissipation box 301, use the heat dissipation channel 302 to generate an air flow that blows on the heat dissipation fins 306 installed on the coolant cooling pipe 305, and use the high-speed flowing air to cool the coolant, so as to ensure that the coolant can assist the connection socket 100 in cooling for a long time. The dust-proof filter net 307 can filter the dust in the air to prevent the dust from accumulating on the heat dissipation fins 306 and affecting its heat dissipation effect; When the temperature sensor 600 detects that the temperature of the connection socket 100 has an abnormal increase and poses a safety hazard, the electronic control valve 506 is activated, so that the carbon dioxide fire extinguisher 503 compresses carbon dioxide and sprays it on the connection socket 100 and the connection plug 102 through the fire sprinkler 505, extinguishing the fire hazard in the first time. The carbon dioxide fire extinguisher 503 is fixed in the fire protection component 500 by using the installation hoop 507 and the installation bolt 508, which facilitates the replacement and maintenance of the carbon dioxide fire extinguisher 503.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
