Description

Technical Field

[0001] This application belongs to the field of electrical assembly technology, specifically relating to a heater integrated module. Background Technology

[0002] For example, in new energy vehicles, components such as compressors and electric heaters are usually driven by high-voltage platforms. Each component has its own wiring harness connectors that connect to the high-voltage lines, resulting in complex layouts, numerous connection processes, and a high risk of errors. This leads to high overall costs and low space utilization. Furthermore, the independent design of compressors and heaters involves their own power control modules, PCB boards, sensors, low-voltage power processing modules, and connectors, which also increases costs. To improve these situations, a modular design scheme integrating compressors and heaters has been proposed. However, this scheme still has problems that need to be solved, mainly the connection between the heater's power supply and temperature detection signals and the integrated control module.

[0003] Currently, the main method is to manually connect the wires separately before installing the heater. This requires reserving space for the wiring operation, resulting in redundant wire length and making it difficult to fix the wires, which affects the reliability of the product.

[0004] The purpose of this application is to solve the problem of connecting the power supply and temperature detection signal of the heater with the integrated control module, reduce the manual operation process, and improve the product assembly efficiency and reliability. Utility Model Content
