Engine compartment wiring harness application areas

Engine Automotive Wiring Harness Are Widely Used In:

  • Passenger cars, commercial vehicles, and new energy vehicles
  • Industrial equipment manufacturing, automotive manufacturing, and machinery
  • Heavy-duty trucks and construction machinery

At JinHai, we use materials and processes tailored to the application environment to ensure our wiring harnesses meet your needs.

Engine Automotive Wiring Harness Communication Standards

Engine Automotive Wiring Harness communication standards mainly include two protocols: CAN (Controller Area Network) and LIN (Local Interconnect Network).

Performance LIN CAN
Medium Access Control Single Master Multiple Master
Typical Bus Speed 2.4 to 19.6 kbd 62.5 to 500 kbd
Multicast Message Routing 6-bit ldentifier 11/29-bit ldentifier
Typical Number of Nodes 2 to 10 Nodes 4 to 20 Nodes
Encoding NRZ 8N1 (USART) NRZ with Bit Stuffing
Data Byte per Frame 2,4,8 Byte 0 to 8 Byte
Transmission Time for

4 Data Bytes

3.5 ms at 20 kbd 0.8 ms at 125 kbd
Error Detection 8-bit Checksum 15-bit CRC
Physical Layer Single Wire, Vbat Twisted Pair, 5V
Clock Generation Master:Crystal,Slaves:RC/Resonator Crystal
Relative Cost per Node 0.5 1

CAN and LIN are suitable for different scenarios in engine compartment wiring harness communication. CAN is used for high-speed, high-reliability key engine control systems, while LIN is used for auxiliary systems of modules with low real-time requirements, such as body control (such as windows and wipers).

After-sales Instructions

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)

B.绝缘层:PVC/XLPE/硅胶等材质

C.连接器:AMP/TE等品牌,含端子、外壳

D.保护材料:波纹管、胶带、编织网等

E.固定件:扎带、支架、卡扣等

F.标识:色标、标签、条码等

A. 温度等级:

PVC:-40℃~105℃(低压系统)

交联聚乙烯(XLPE):125℃(发动机舱)

硅胶:-60℃~200℃(新能源高压)

B.机械性能:

耐磨:TPE/TPU优于PVC

柔韧性:硅胶最优
