Description

Technical Field

[0001] The utility model relates to the technical field of automotive wiring harnesses, especially the high-voltage and low-voltage wiring harnesses of new energy vehicles. Background Art

[0002] With the continuous development of the new energy vehicle industry, automotive electrical appliances and other control systems are also constantly developing towards refined functions, complex structures and diversification. Various wiring harnesses and pipelines run through the vehicle body vertically and horizontally. High-voltage wiring harness connectors have been widely developed and applied in China and internationally. In particular, the application of high-voltage wiring harness connectors in pure electric vehicles and hybrid electric vehicles has become an important research content.

[0003] For example, Chinese authorized announcement number CN 219642592 U discloses a high-voltage and low-voltage wiring harness convenient for connection, including a wiring harness device. An installation facilitating mechanism is fixedly connected to the outside of the wiring harness device, a connection mechanism is fixedly connected to the outside of the wiring harness device, and a first connecting wire is fixedly connected to the outside of the installation facilitating mechanism. By pulling the connecting rod movably connected to the outside of the housing of the utility model, the turntable can be rotated, thereby driving the clamping block to move in the arc-shaped groove opened in the turntable. Since the outside of the clamping block is movably connected with a limiting plate, the limiting plate can move along the sleeve rod, so that the limiting plate clamps the wire. Then, by rotating the threaded block for limiting, the effect of convenient installation is achieved. By rotating the second sleeve, the slider can move along the arc-shaped groove opened in the first sleeve, thereby driving the second sleeve to be inserted into the first sleeve. Then, by rotating the bolt into the limiting hole for limiting, the effect of convenient connection of the wiring harness is achieved.

[0004] By checking the above comparative documents, it can be seen that there is a problem of inconvenient connection of the wiring harness in the prior art. Moreover, when the plug on the wiring harness is connected to the connector, although the plug and the connector can be connected by using the bolt fixing method, during the connection process, tools such as screwdrivers are often required to turn the bolts. If there is no screwdriver at the connection site, it is difficult to complete the connection work. And when separating the connector from the plug, a screwdriver is also needed to loosen the bolt, which makes the plugging and unplugging operation of the plug and the connector not convenient enough. Therefore, how to make the plugging and unplugging work of the plug and the connector on the wiring harness more convenient remains to be improved. Summary of the Utility Model

[0005] The utility model provides a high-voltage and low-voltage wiring harness for new energy vehicles, which is conducive to making the plugging and unplugging work of the plug and the connector on the wiring harness more convenient.

[0006] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0013] Furthermore, the clamping blocks are all fixed to the left end of the inner side of the limiting plate, a clamping groove matching the clamping block is opened on the outer side of the limiting block, and the left side of the clamping block is inclined.

[0014] Furthermore, the buckle limit assembly also includes a movable block, a return spring and a pressure block.

[0015] Beneficial effects of the utility model:

[0016] 1. By inserting the sealing sleeve into the sealing groove, and setting an outer sealing ring between the connector and the plug, and inserting the inner sealing ring on the sealing sleeve into the sealing groove, it is convenient to perform multiple sealing on the connection between the connector and the plug, so as to prevent external dust or water stains from entering the connection port of the connector after connection, thereby avoiding the occurrence of poor contact after connection;

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For the convenience of understanding by those skilled in the art, the present invention will be further described below in conjunction with the embodiments and the drawings. The content mentioned in the embodiments does not limit the present invention.

[0026] Such as Figure 1 , 2As shown in FIGS. 4 and 5, in this embodiment, it includes a wire harness body 1 and a plug 2. The plug 2 is connected to the end of the wire harness body 1. A connector 3 is provided at the left end of the plug 2. A connection port 4 is opened on the right side of the connector 3. A connection head 5 inserted into the connection port 4 is fixed on the left side of the plug 2. A sealing sleeve 9 fixed to the left side of the plug 2 is sleeved around the periphery of the connection head 5. A sealing groove 10 located outside the connection port 4 is opened on the right side of the connector 3. An outer sealing ring 8 connected to the left side of the plug 2 is sleeved outside the sealing sleeve 9. An inner sealing ring 11 is connected to the left end of the sealing sleeve 9. Both the sealing sleeve 9 and the inner sealing ring 11 are adapted to the sealing groove 10.

[0027] On the premise that the connection head 5 is inserted into the connection port 4, at this time, the sealing sleeve 9 is inserted into the sealing groove 10. Moreover, an outer sealing ring 8 is provided between the connector 3 and the plug 2. After the connector 3 and the plug 2 press the outer sealing ring 8 tightly, combined with the inner sealing ring 11 on the sealing sleeve 9 being inserted into the sealing groove 10, it is beneficial to perform multiple seals on the connection between the connector 3 and the plug 2, avoiding external dust or water stains from entering the connection port 4 of the connector 3 after connection, thereby avoiding the occurrence of poor contact after connection.

[0028] As Figures 1-3 shown, in this embodiment, the plug 2 is rotatably connected with a rotating shaft 18 above and below. A rocker 17 is fixed to the right side of each rotating shaft 18. A return spring 19 is connected between each rocker 17 and the plug 2. Snap - limit components are provided at the upper and lower ends of the connector 3. Each snap - limit component includes a limit plate 6, a limit block 7 and a clamping block 13. The limit plates 6 are fixed to the left side of the rotating shafts 18. The limit blocks 7 are fixed outside the connector 3. The right side of the limit block 7 is inclined. The clamping blocks 13 are fixed to the left end of the inner side of the limit plate 6. A card slot 12 matching the clamping block 13 is opened on the outer side of the limit block 7. The left side of the clamping block 13 is inclined. Each snap - limit component further includes a movable block 14, a return spring 16 and a pressing block 15. The movable blocks 14 are hinged outside the connector 3. The return springs 16 are connected between the movable blocks 14 and the connector 3. The pressing blocks 15 are fixed to the right side of the movable blocks 14. The inner side of the pressing block 15 is inclined. The inner side of the pressing block 15 abuts against the outer edge of the limit plate 6.

[0029] When it is necessary to pull out the connection head 5 from the connection port 4, on the premise that the clamping block 13 is stuck in the card slot 12, after holding the plug 2 by hand and then pressing the two rockers 17 simultaneously, the rocker 17 drives the rotating shaft 18 to rotate. The rotating shaft 18 will drive the limit plate 6 and the clamping block 13 to move outward, so that the limit plate 6 presses the pressing block 15 outward. The pressing block 15 will drive the movable block 14 to compress the return spring 16 until the limit plate 6 drives the clamping block 13 out of the card slot 12. Then, the connection head 5 can be conveniently pulled out from the connection port 4, and it is beneficial to conveniently separate the plug 2 from the connector 3.

[0030] As shown Figures 1-3 in the figure, in this embodiment, the limiting plates 6 are all fixed to the left side of the rotating shaft 18, the limiting blocks 7 are all fixed outside the connector 3, the right side of the limiting block 7 is inclined, the clamping blocks 13 are all fixed to the left end inside the limiting plate 6, a clamping groove 12 matching the clamping block 13 is formed on the outer side of the limiting block 7, and the left side of the clamping block 13 is inclined.

[0031] When the plug 2 needs to be connected to the connector 3, the connecting head 5 on the plug 2 is inserted into the connecting port 4 on the connector 3. During this process, the inclined surface of the clamping block 13 slides along the inclined surface of the limiting block 7, and at the same time, the limiting block 7 pushes the clamping block 13 outwards, so that the clamping block 13 drives the limiting plate 6, the rotating shaft 18 and the rocker 17 to rotate. The rocker 17 compresses the return spring 19. Until the clamping block 13 moves to the notch of the clamping groove 12, the return elastic force of the return spring 19 drives the rocker 17, the rotating shaft 18, the limiting plate 6 and the clamping block 13 to rotate and reset. Therefore, the clamping block 13 will automatically snap into the clamping groove 12. When the plug 2 or the connector 3 is pulled left and right accidentally, the clamping block 13 is limited by the clamping groove 12 on the limiting block 7, so as to avoid the connecting head 5 from loosening in the connecting port 4 and prevent the connector 3 from separating from the plug 2.

[0032] In summary, the elastic force of the return spring 19 drives the clamping block 13 to snap into the clamping groove 12, and the elastic force of the reset spring 16 drives the pressing block 15 to press the limiting plate 6, so as to facilitate the stable clamping of the clamping block 13 in the clamping groove 12, facilitate the insertion of the connecting head 5 into the connecting port 4, so as to conveniently connect the plug 2 to the connector 3, and avoid the connecting head 5 from loosening in the connecting port 4 and prevent the connector 3 from separating from the plug 2. And only by pressing the two rockers 17 at the same time, the clamping block 13 can be conveniently driven out of the clamping groove 12. Therefore, it is convenient to pull out the connecting head 5 from the connecting port 4 and separate the plug 2 from the connector 3. In summary, compared with the prior art, there is no need to use a screwdriver to operate bolts for connection, which is beneficial to the more convenient plugging and unplugging of the plug 2 on the wire harness and the connector 3.

[0033] All technical features in this embodiment can be freely combined according to actual needs.

[0034] The above embodiment is a preferred implementation scheme of the present invention. In addition, there are other implementation methods. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
