Description

Technical Field

[0001] The invention relates to a high-voltage wire harness splitting device and method, in particular to a high-voltage wire harness splitting device and method for automobiles, belonging to the technical field of high-voltage wire harness splitting. Background Art

[0002] As an important carrier for transmitting electric energy in the high-voltage system of electric vehicles, high-voltage wiring harnesses are very different from low-voltage wiring harnesses in terms of both electrical performance and physical characteristics. High-voltage wiring harnesses have important characteristics and higher protection levels that are far higher than traditional low-voltage wires. High-voltage wiring harnesses and low-voltage wiring harnesses are divided into upper and lower hierarchical relationships. In order to avoid the risk of electromagnetic interference caused by high-voltage wiring harnesses when transmitting strong currents, which may cause electromagnetic interference to the power supply and signal transmission of the control unit by the low-voltage wiring harness, a layered design of high-voltage wiring harnesses and low-voltage wiring harnesses is generally adopted; due to the different current sizes of different models, the distance between the high-voltage and low-voltage wire layers is generally guaranteed to be within 200-300mm. After actual vehicle verification, this solution effectively avoids interference caused by strong electricity. Layered wiring can effectively protect against EMC interference generated when high-voltage lines are working.

[0003] Chinese patent number CN114765356B provides a high-voltage wire harness splitting device and method for new energy vehicles, including a shell, an inlet fixing device is fixedly arranged at one end of the shell, a first high-voltage wire and a second high-voltage wire are clamped in the inlet fixing device, the first high-voltage wire is clamped by a pre-bending clamping device and a post-bending clamping device inside the shell, side closure structures are hinged on both sides of the shell, a rectangular through hole is opened on the side opposite to the side cover of the shell, a wire moving device is arranged in the rectangular through hole, and a circulating cooling device is fixedly arranged in the middle of the upper surface of the shell. However, although the above-mentioned high-voltage wire harness splitting device controls the post-bending clamping device through the data in the pre-bending clamping device, the first high-voltage wire can be clamped without the need to set up a detection device separately, and the cost is saved at the same time, the high-voltage wire harness is easily confused in the wire sleeve, which is not convenient for later maintenance and sorting, and it is not convenient for splitting. At the same time, it is not convenient to install, fix and connect after splitting, and the wire sleeve does not have the function of protecting and protecting the high-voltage wire harness.

Wiring: Fix one end of the main line (111) to one side of the connection base (101), and perform wiring according to the number of high-voltage wire harnesses used in the vehicle; S2, clamping: selecting an appropriate number of clamping frames according to the number of main lines (111), plugging a connecting column (206) on the clamping frame into a plugging slot (205) on one side of another clamping frame, and then fixing them with bolts, increasing or decreasing the number of clamping frames to meet the use of different numbers of high-voltage wire harnesses, and selecting an appropriate clamping sleeve (204) according to the diameter of the main line (111) to meet the use of main lines (111) with different diameters, and then clamping the clamping sleeve (204) into the clamping slot (203); S3, packaging: sleeve the wire set (103) onto the outside of the main wire (111) and the clamping assembly (200); S4, tapping: the wires to be tapped are connected to the tapping seat (301), and the tapped main wire (111) is connected to the first wiring seat (302), and then the threads at both ends of the tapping wire bundle (303) are threaded onto the wiring seat, and at the same time; S5, wiring: plug the wire that needs to be connected to the main wire (111) into the plug hole (105) on the other side of the main wiring seat (102), and then install the branch wire (309) into the wiring hole (308), and the branch wire of the automobile high-voltage wire harness is completed; S6. Installation: The connection base (101) is installed on the main wiring base (102) by bolts. At the same time, the main wiring base (102) is fixed to a designated position by bolts and first mounting plates (109) on both sides. The limit frame (401) is clamped to the outside of the line assembly (103). Then, the main line assembly (100) is fixed to a designated position by the limit plate (402) and bolts. Then, the branch wiring base (306) is installed at the designated position of the branch line by bolts.
