  工程人经常会碰到别人问这个数据怎么来的,依据是什么,含糊不清的回答只会让人感觉你不专业,例如线束加工最基础的剥皮尺寸,很多工程师都是依据经验或找实物测量来定义长度的。事实上这一经常被忽视的工序也是有依据的。
 
  Engineers often come across people asking how this data came from, based on what, vague answers will only make you feel unprofessional, such as harness processing the most basic stripping size, many engineers are based on experience or find physical measurement to define the length. In fact, this often neglected process is also based.
 
  剥皮尺寸参考计算方法(引用无焊压接连接一般要求、试验方法和使用导则 GB-T 18290.2-2000),如下图:
 
  Reference calculation method for peeling dimension (referring to general requirements, test methods and guidelines for use of weldless compression joints GB-T 18290.2-2000), as follows:
 
  这种情况特别适用与日企台企等大中型企业,凡事都需要个依据标注的情况下。
 
  This situation is particularly applicable to large and medium-sized enterprises such as Japanese enterprises and Taiwan enterprises, where everything needs a basis for annotation.
线束加工
 
  接下来说说压接,压接作为线束加工的最重要工序,也是各个加工厂彰显技术实力和质量意识的关键点所在,大部分要求从业者都应该知道,说一些比较偏门的,如下:
 
  Next, as the most important process of wiring harness processing, crimping is also the key point of each processing factory to highlight the technical strength and quality awareness. Most of the practitioners should know that, say some of the more partial, as follows:
 
  什么决定压接质量的好坏?
 
  What determines the quality of crimping?
 
  一、良好的电性能
 
  1. Good electrical properties
 
  ①低而稳定的电阻抗;②抗腐蚀性
 
  (1) low and stable electrical impedance; 2. Corrosion resistance.
 
  二、良好的机械性能
 
  Two. Good mechanical properties
 
  较高的拉力
 
  Higher tensile force
 
  三、良好的物理属性
 
  Three. Good physical properties
 
  ①合理的芯线变形;②适中的喇叭口;③小毛刺;④合适的压接高度比
 
  (1) reasonable deion of the core wire; (2) moderate bell mouth; (3) small burr; (4) suitable crimping height ratio.
 
  在压接过程中主要抓的是拉力和高宽度。事实上在肉眼无法测量的情况下,有个数据也是很重要且专业的,那就是压缩比。
 
  In the crimping process, the main force is tension and high width. In fact, when the naked eye can not measure the situation, there is a data is also very important and professional, that is, compression ratio.
