JinHai Is a High-Tech Manufacturer Using High-Quality Standard Materials

JinHai uses high-quality components and materials that meet the stringent UL94 V-0 flame retardant standards, avoiding heat source risks and ensuring the comfort and safety of the air-conditioning wiring harness for the vehicle.

Features of Air Conditioning Wiring Harness

  • Mechanical Reliability: The connector’s fixed structure ensures the wiring harness remains secure across a frequency range of 50Hz to 2000Hz.
  • High Integration: A single wiring harness connects all critical components of the air conditioning system.
  • Fully Flame-Retardant Safety: Complies with the stringent UL94 V-0 flame-retardant standard.
  • Chemical Resistance: Constructed using high-quality materials that meet industry standards.

Air Conditioning Wiring Harness Application Areas

Vehicle type Differences in wiring harness characteristics
Traditional fuel vehicles Low voltage system (12V/48V), mainly PVC insulation, arranged around the engine compartment.
New Energy Vehicles High voltage system (300V-800V) requires silicone/cross-linked polyethylene insulation, multi-layer shielding for EMI protection, and long-distance wiring in the chassis.

 

Air Conditioning Wiring Harness Communication Standard

Mainstream protocols

CAN bus: The mainstream bus for fuel-powered vehicles, with a maximum speed of 1Mbit/s and a transmission distance of up to 5kbit/s at distances up to 10km. It is suitable for transmitting compressor control signals.

Ethernet: A trend in new energy vehicles, it supports high-speed data transmission exceeding 100Mbit/s, meeting the needs of intelligent temperature control and vehicle-mounted computer connectivity.

How to handle quality issues or returns?

At JinHai, if there are any quality issues with the goods we ship, we generally handle them in the following three ways:

  • If the product cannot be repaired, JinHai will directly send the customer a good product to replace the defective one;

  • If the product is repairable, JinHai will negotiate with the customer and coordinate with a third party approved by the customer to assist with the repair, and the cost will be borne by JinHai;

  • Under normal order conditions, JinHai will give customers products at a rate of 0.1% of the order amount for later product maintenance or replacement.

Quality begins with details, and service builds trust. The Jinhai after-sales team is dedicated to resolving your issue!

FAQ

什么是线束?和普通电缆有什么区别?

线束是由多根电线/电缆、连接器、端子、保护套管等组件,通过捆扎、包裹等方式组成的集成化电气连接系统。与普通电缆相比:

A.集成度:线束是多线路系统化集成,电缆是单根导体

B.功能:线束实现多点互联和信号分配,电缆仅传输电能/信号

C.定制性:线束需根据应用场景定制设计,电缆多为标准件

D.防护:线束具有整体防护结构(波纹管、胶带等),电缆多为单一绝缘层

一条标准线束包含:

A.导体:多股铜线(常规信号传输应用)或单芯线(高频信号传输应用)
