Description

Technical Field

[0001] The present invention relates to the technical field of wire harness fixing, and in particular to a high-voltage wire harness connector for new energy vehicles. Background Art

[0002] The automotive high-voltage wire harness connector is a connection component designed specifically for the high-voltage electrical system of new energy vehicles. It is also a core component to ensure the reliability and safety of the high-voltage system. Its structure is generally divided into two parts: the sub-end and the female end. After the sub-end and the female end are connected separately, they can be connected to achieve the connection between the wire harnesses.

[0003] However, the existing connectors are not stable enough after connection. When the male end and the female end need to be separated, the disassembly is not convenient and labor-saving enough, and it is easy to twist during separation, thereby damaging the connector port. Summary of the invention

[0004] In order to overcome the shortcomings mentioned in the background technology, the present invention provides a new energy vehicle high-voltage wiring harness connector which makes the connector more stable after connection, more convenient and labor-saving when disassembling, and not prone to twisting when separating.

[0005] The technical solution is: a high-voltage wiring harness connector for new energy vehicles, comprising two connecting tubes, three grooves are opened on the two side planes of the connecting tubes, a connecting sub-end and a connecting female end are fixedly connected to the two connecting tubes respectively, a plurality of strip grooves are opened on the surface of the connecting sub-end, two square grooves are opened on the connecting sub-end, and two straight grooves are opened on the inner wall of the connecting female end. An adjustable mechanism is arranged on the two connecting tubes, and the adjustable mechanism is used to adjust the wiring angle according to the wiring environment. A limiting mechanism is arranged on the connecting sub-end, and the limiting mechanism is connected to the connecting female end. The limiting mechanism is used to maintain the stability of the connection after the connecting sub-end and the connecting female end are in contact and connected.

[0006] Furthermore, the adjustable mechanism includes four swing arms, two of the swing arms form a group, and the two groups of swing arms are rotatably connected to the two connecting tubes respectively, and a fixing frame is fixedly connected between the two swing arms in each group, and the fixing frame is provided with a plurality of through holes, and each of the swing arms is slidably connected to a round head clamping rod, and one end of the round head clamping rod is located in one of the grooves on the connecting tube, and a pressure spring is connected between the round head clamping rod and the swing arm, and each of the fixing frames is threadedly connected to a plurality of fastening screws, and a plurality of spring rings are fixedly connected to the side of each fixing frame, and a plurality of bent conductive plates and a straight conductive plate are fixedly connected to one side of the connecting sub-end and the connecting female end, and the straight conductive plate and the bent conductive plate are both connected to the connecting tube.

[0007] Furthermore, the limiting mechanism includes two support platforms, both of which are fixedly connected to the connecting female end, a toggle frame is slidably connected between the two support platforms, two magnet blocks are fixedly connected to one side of the toggle frame, two positioning blocks are fixedly connected to the connecting female end, a positioning block is provided with a slot, a supporting inclined plate is fixedly connected to the connecting sub-end, two spring sheets are fixedly connected to one side of the supporting inclined plate, the ends of the two spring sheets away from the supporting inclined plate are fixedly connected to an inclined surface block, each of the inclined surface blocks is fixedly connected to an iron plate, and a connecting toggle plate is fixedly connected between the two inclined surface blocks.

[0008] Furthermore, it also includes a quick-release mechanism, which is arranged on the connecting female end, and is used to make the separation between the connecting sub-end and the connecting female end more convenient. The quick-release mechanism includes two support rods, and the two support rods are fixedly connected to the connecting female end. A rotating roller is rotatably connected between the two support rods, a support block is fixedly connected to the connecting female end, and a wheel frame is rotatably connected to the support block, and a plurality of strip-shaped protrusions are arranged on the wheel frame. Two side rods are fixedly connected to the lower part of the toggle frame, and resistance blocks are fixedly connected to one end of the two side rods close to the wheel frame. A bevel gear is fixedly connected to the rotating shaft of the rotating roller, and a toothed disc is fixedly connected to one side of the wheel frame, and the toothed disc meshes with the bevel gear. A nut is fixedly connected to the side of the rotating roller away from the bevel gear.

[0009] Furthermore, it also includes a straight-pull mechanism, which is arranged on the connecting sub-end and is used to separate the two terminals horizontally. The straight-pull mechanism includes two piston cylinders, and the two piston cylinders are fixedly connected to the connecting sub-end. The two piston cylinders are slidably connected with piston rods, a return spring is connected between the piston rods and the piston cylinders, a pressure frame is fixedly connected between the two piston rods, and the bottoms of the two square grooves on the connecting sub-end are fixedly connected with strip air bags, and a connecting pipe is fixedly connected between the strip air bags and the piston cylinders.

[0010] The beneficial effects are as follows: 1. The inclined card block is inserted into the card slot on the card block, and then the frame is moved horizontally for a distance to contact the upper surface of the inclined card block, limiting the inclined card block, so that the connection between the sub-end and the female end is more stable.

[0011] 2. In real situations, since the connection time between the connector sub-end and the connector female end is too long and too tight, it is difficult to separate the connector sub-end and the connector female end. When separating the connector sub-end and the connector female end, the operator first makes the toggle frame no longer limit the inclined surface block, and the inclined surface block no longer limits the positioning block, and then rotates the rotating roller. The rotation of the rotating roller will drive the toothed disc to rotate through the bevel gear, and the rotation of the toothed disc will drive the wheel frame to rotate together. The rotation of the wheel frame will push the connector sub-end out of the connector female end through the cooperation of the strip protrusion and the strip groove. When it is difficult to rotate the rotating roller by hand, a wrench can be used to rotate the nut to drive the rotating roller to rotate. This makes the separation of the connector sub-end and the connector female end more convenient and labor-saving.

[0012] 3. When the pressure frame is squeezed by other objects, the return spring is compressed, and the pressure frame is squeezed and moves downward, which will drive the piston rod to move downward. The downward movement of the piston rod will squeeze the air in the piston cylinder into the strip airbag, and then the strip airbag will expand. A part of the expanded strip airbag will be squeezed into the straight groove on the inner wall of the female end of the connector. Then, a part of the expanded strip airbag is in the square groove on the connector sub-end, and a part of it is in the straight groove on the inner wall of the connector female end. Then, the greater the squeezing force on the pressure frame, the greater the distance the pressure frame moves downward, and then the greater the distance the piston rod is driven to move downward, the greater the degree of expansion of the strip airbag. The greater the degree of expansion of the strip airbag, the inner wall of the square groove on the connector sub-end and the inner wall of the straight groove on the inner wall of the connector female end will be squeezed, and the friction between them will be increased, so that the two parts of the connector can actively improve the stability when they are squeezed, and they are not easy to separate.

DETAILED DESCRIPTION

[0025] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0026] Example 1 A high voltage wiring harness connector for new energy vehicles, such as Figure 1-11 As shown, it includes two connecting tubes 1, three grooves are opened on the two side planes of the connecting tubes 1, and the two connecting tubes 1 are respectively fixedly connected with a connecting sub-end 2 and a connecting female end 3, and a plurality of strip grooves are opened on the surface of the connecting sub-end 2, two square grooves are opened on the connecting sub-end 2, and two straight grooves are opened on the inner wall of the connecting female end 3. Adjustable mechanisms are provided on the two connecting tubes 1, and the adjustable mechanisms are used to adjust the wiring angle according to the wiring environment. A limiting mechanism is provided on the connecting sub-end 2, and the limiting mechanism is connected to the connecting female end 3. The limiting mechanism is used to maintain the stability of the connection after the connecting sub-end 2 and the connecting female end 3 are in contact and connected.

[0027] The adjustable mechanism includes four swing arms 41, two of the swing arms 41 form a group, and the two groups of swing arms 41 are rotatably connected to the two connecting tubes 1 respectively, and a fixing frame 42 is fixedly connected between the two swing arms 41 of each group, and the fixing frame 42 has a plurality of through holes, and each of the swing arms 41 is slidably connected to a round head clamping rod 43, one end of the round head clamping rod 43 is located in one of the grooves on the connecting tube 1, and a pressure spring 44 is connected between the round head clamping rod 43 and the swing arm 41, and each of the fixing frames 42 is threadedly connected to a plurality of fastening screws 45, and each of the fixing frames 42 is fixedly connected to a plurality of spring rings 46 on the side, and a plurality of bent conductive plates 47 and a straight conductive plate 48 are fixedly connected to one side of the connecting sub-end 2 and the connecting female end 3, and the straight conductive plate 48 and the bent conductive plate 47 are both connected to the connecting tube 1.

[0028] The limiting mechanism includes two support platforms 51, and the two support platforms 51 are fixedly connected to the connecting female end 3. A toggle frame 52 is slidably connected between the two support platforms 51, and two magnet blocks 53 are fixedly connected to one side of the toggle frame 52. Two positioning blocks 54 are fixedly connected to the connecting female end 3, and a positioning block 54 is provided with a slot. A supporting inclined plate 55 is fixedly connected to the connecting sub-end 2, and two spring sheets 56 are fixedly connected to one side of the supporting inclined plate 55. The ends of the two spring sheets 56 away from the supporting inclined plate 55 are fixedly connected to an inclined surface block 57, and each of the inclined surface blocks 57 is fixedly connected to an iron plate 58. A connecting toggle plate 59 is fixedly connected between the two inclined surface blocks 57.

[0029] The connector is composed of two parts, the sub-end and the female end. The operator first connects the wire harness to the sub-end and the female end respectively, and then connects the two parts together to achieve connectivity between the wire harnesses. In actual work, the operator first needs to pass the wire harness through the spring ring 46, insert it into the fixing frame 42, and make the front end of the wire harness contact with the straight conductive plate 48. Then the operator tightens each fastening screw 45 so that the fastening screw 45 squeezes the wire harness in the fixing frame 42 to complete the fixation of the wire harness. Since the straight conductive plate 48 and the bent conductive plate 47 are both connected to the connecting sub-end 2 and the connecting female end 3, the wire harness is also electrically connected to the connecting sub-end 2 and the connecting female end 3. In the wiring harness connection work of new energy vehicles, due to the different spatial environment inside the car, the wiring harness needs to be bent to fit the surface of the internal structure of the car. Then the operator can pull up the round head clamp rod 43 before wiring, and make the fixing frame 42 rotate 90°, and then put down the round head clamp rod 43, so that the round head clamp rod 43 is stuck in another groove, and then the operator can connect the wires. Since the fixing frame 42 rotates 90°, after the operator connects the wires, the front end of the wire harness contacts the bent conductive plate 47. In this way, by rotating the fixing frame 42, the wiring angle is different, which can make the wiring harness connection more convenient in a narrow environment. After the wiring is completed, the operator connects the sub-terminal 2 is horizontally aligned with the connecting female end 3, and the connecting sub-end 2 is horizontally inserted into the connecting female end 3. When the connecting sub-end 2 is horizontally inserted into the connecting female end 3, the inclined card block 57 will be stuck in the card slot on the card block 54, and the connecting sub-end 2 and the connecting female end 3 are limited. When the connecting sub-end 2 is horizontally inserted into the connecting female end 3, the distance between the magnet block 53 and the iron plate 58 is continuously reduced. After the inclined card block 57 is stuck in the card slot on the card block 54, the magnet block 53 will move horizontally for a distance toward the direction close to the iron plate 58 under the action of magnetic force, and the magnet block 53 will eventually attract the iron plate 58. The horizontal movement of the magnet block 53 will drive the toggle frame 52 to move horizontally together. After a certain distance, the toggle frame 52 will contact the upper surface of the inclined surface block 57 after moving horizontally for a certain distance, so that the toggle frame 52 can limit the inclined surface block 57, so that the connection between the connecting sub-end 2 and the connecting female end 3 is more stable. When the connecting sub-end 2 and the connecting female end 3 need to be disassembled and separated, the operator only needs to push the toggle frame 52 to separate the iron plate 58 from the magnet block 53, and the toggle frame 52 is no longer in the limiting inclined surface block 57, and then toggle the connection dial plate 59 to drive the inclined surface block 57 to swing upward, and the spring sheet 56 is deformed, so that the inclined surface block 57 is separated from the positioning block 54, and then the connecting sub-end 2 and the connecting female end 3 are horizontally separated.

[0030] Example 2 On the basis of Example 1, Figure 6-7As shown, a quick-release mechanism is also included, which is arranged on the connecting female end 3. The quick-release mechanism is used to make the separation between the connecting sub-end 2 and the connecting female end 3 more convenient. The quick-release mechanism includes two support rods 61, and the two support rods 61 are fixedly connected to the connecting female end 3. A rotating roller 62 is rotatably connected between the two support rods 61. A supporting block 63 is fixedly connected to the connecting female end 3, and a wheel frame 64 is rotatably connected to the supporting block 63. A plurality of strip-shaped protrusions are provided on the wheel frame 64. Two side rods 65 are fixedly connected to the lower part of the toggle frame 52, and resistance blocks 66 are fixedly connected to one end of the two side rods 65 close to the wheel frame 64. A bevel gear 67 is fixedly connected to the rotating shaft of the rotating roller 62, and a toothed disc 68 is fixedly connected to one side of the wheel frame 64, and the toothed disc 68 meshes with the bevel gear 67. A nut 69 is fixedly connected to the side of the rotating roller 62 away from the bevel gear 67.

[0031] At first, after the connecting sub-end 2 and the connecting female end 3 are connected, the strip protrusion on the wheel frame 64 will cooperate with the strip groove on the connecting sub-end 2, and the toggle frame 52 will move horizontally for a distance together with the magnet block 53, and the toggle frame 52 will also drive the side rod 65 and the resistance block 66 to move horizontally for a distance, so that the resistance block 66 squeezes the side of the wheel frame 64 to prevent the wheel frame 64 from rotating. In a real situation, since the connecting sub-end 2 and the connecting female end 3 are connected for too long and too tightly, it is difficult to separate the connecting sub-end 2 and the connecting female end 3. When separating the connecting sub-end 2 and the connecting female end 3, the operator The operator first makes the toggle frame 52 no longer limit the inclined surface block 57, and the inclined surface block 57 no longer limits the blocking block 54, and then rotates the rotating roller 62. The rotation of the rotating roller 62 will drive the toothed disc 68 to rotate together through the bevel gear 67, and the rotation of the toothed disc 68 will drive the wheel frame 64 to rotate together. The rotation of the wheel frame 64 will push the connecting sub-end 2 out of the connecting female end 3 through the cooperation of the strip protrusion and the strip groove. When it is difficult to rotate the rotating roller 62 by hand, the nut 69 can be turned with a wrench to drive the rotating roller 62 to rotate, which makes it more convenient and labor-saving to separate the connecting sub-end 2 and the connecting female end 3.

[0032] Example 3 On the basis of Example 2, Figure 8-11As shown, it also includes a straight-pull mechanism, which is arranged on the connecting sub-end 2. The straight-pull mechanism is used to separate the two terminals horizontally. The straight-pull mechanism includes two piston cylinders 71, and the two piston cylinders 71 are fixedly connected to the connecting sub-end 2. The two piston cylinders 71 are slidably connected with piston rods 72, and a return spring 73 is connected between the piston rods 72 and the piston cylinders 71. A pressure frame 74 is fixedly connected between the two piston rods 72. The bottoms of the two square grooves on the connecting sub-end 2 are fixedly connected with strip air bags 75, and a connecting pipe 76 is fixedly connected between the strip air bags 75 and the piston cylinders 71.

[0033] After the connecting sub-end 2 is horizontally inserted into the connecting female end 3, when the pressure-bearing frame 74 is squeezed by other objects, the return spring 73 is compressed, and the pressure-bearing frame 74 is squeezed and moves downward, which drives the piston rod 72 to move downward. The downward movement of the piston rod 72 squeezes the air in the piston cylinder 71 into the strip airbag 75, and then the strip airbag 75 will expand. A part of the expanded strip airbag 75 will squeeze into the straight groove on the inner wall of the connecting female end 3, and a part of the expanded strip airbag 75 will be in the square groove on the connecting sub-end 2. Part of it is in the straight groove on the inner wall of the connecting female end 3, and then the greater the squeezing force on the pressure-bearing frame 74, the greater the distance the pressure-bearing frame 74 moves downward, and then the greater the distance the piston rod 72 moves downward, the greater the degree of expansion of the strip air bag 75. The greater the degree of expansion of the strip air bag 75, the inner wall of the square groove on the connecting sub-end 2 and the inner wall of the straight groove on the inner wall of the connecting female end 3 will be squeezed, and the friction between them will be increased, so that the two parts of the connector can actively improve the stability when being squeezed, and are not easy to separate.

[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
