Easy Maintenance: Clear and organized wiring allows for easy identification of problems, making repairs and replacements quick and easy, saving time and labor.
Standard Design: Standardized wiring reduces the risk of tangles and friction fires, protecting the engine and the entire machine.
Our purchasing department uses a global strategy to source quality components from special channels.
Adhering to IPC/WHMA-A-620 standards, we ensure reliability and performance in each product.
JinHai’s agricultural machinery engine wiring harnesses have a wide range of applications, primarily covering the following scenarios:
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!
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
C.环保要求：符合ROHS/REACH
成本：PVC＜XLPE＜硅胶
诊断流程：
A.测量回路电阻（标准值＜0.5Ω，使用高精度毫欧表，分辨率：0.1mΩ）
B.进行振动测试（20-2000Hz扫频，红外热像仪）
C.使用微欧计检测接触电阻
重点检查：
A.端子压接区（截面分析）
B.连接器锁止机构
C.线束弯曲半径过小处
A.采用”蛇形布线”（预留10%长度余量）
B.固定点间距≤200mm
C.使用PA66材质支架（耐温120℃)
D.导线：0.3mm²细绞线（比常规线柔韧性提升25%）
E.绝缘层：TPE-S（动态弯曲寿命＞50万次）
F.端子压接：实施剖面分析
G.点胶固定：汉高乐泰3265结构胶（剪切强度＞15MPa）
