In the era when VR technology is not surprising, the era of virtualization has begun to show. In the industrial kingdom, automation is what we have been popularizing. With the continuous improvement of the automation level in the wire processing process, the crimping terminal process no longer depends on manpower. Automatic machines have emerged as the times require, and work efficiency has been greatly improved.

The influence of wires on crimping terminals

The crimping of the wire and the terminal refers to the close combination of the contact surface of the wire and the terminal through a certain mechanical external force. The process is achieved by closing the upper and lower blades of the crimping die, so as to achieve the purpose of firm bonding of the electrical conductors. . Good terminal crimping can reduce electrical resistance, reduce copper wire oxidation at crimping, and have various excellent properties such as firm tightness and good electrical conductivity. Therefore, precise crimping tools can ensure good crimping quality. At present, there are three types of crimping tools: manual crimping tools, semi-automatic crimping equipment, and fully automatic crimping equipment.

The process of wire processing

The warehouse picks materials and prepares the corresponding wires;

Debug the machine and adjust the crimping parameters, then crimp in small batches;

Visually check whether the crimping of the terminal meets the specifications, such as the shape of the terminal, the position of the crimping, and the size of the terminal;

Perform tensile testing on the crimped samples, and check whether they meet the standards according to the requirements of crimping parameters.

The main factors affecting the quality of crimping terminals

There are many factors for the quality of crimping terminals. The wire diameter that any terminal can adapt to has a certain range, and the wire diameter is an important factor that affects the quality of crimping. Secondly, there are also some reasons for the wire. Different countries, different manufacturers, and different batches of products have certain differences. In the case of the same wire diameter, the thickness of the insulating sheath will be different, and the quality and effect of the crimping will be different; in addition, the material and thickness of the terminal are also an important factor. In general, the parameters that affect the quality of crimping terminals include crimping force, wire diameter and terminal structure. During the specific crimping process, the terminal wire processing manufacturer should pay attention to the following points:

• Reasonable wire diameter, suitable crimp height ratio and suitable burr height and width;

• 
  

• The length of the stripped part of the wire should be appropriate;

• 
  

• The crimping mold has no impurities, and the crimping shape meets the specifications;

• 
  

• After crimping, it must go through a tensile test, and then it can be crimped in batches after being qualified.

Crimp terminal inspection specification

For the inspection of the appearance and shape of the crimping terminal, the purpose is to check the crimping defects and mold defects that were not detected in the tensile test, and to further determine whether the crimping state is good or not, so as to avoid the incompatibility of the subsequent plug-in process. In the case of crimping tension and height guarantee, the ideal crimping state should meet the following requirements:

• The core wire can be seen between the insulation layer and the core wire crimping area, and the insulation layer can be seen. It is best to have half the insulation layer and core wire;

• 
  

• The exposed length of the core wire between the core wire crimping area and the plug-in area is usually 0.5～1.5mm;

• 
  

• There should be bell mouths on both sides of the core wire crimping area, if there is only one side, it should be on the side of the insulation layer;

• 
  

• The core wire crimping area and insulation lamination area shall not be deformed or damaged;

• 
  

• There must be no deformation in the plug-in area, and the bayonet piece must not be deformed;

• 
  

• There should be no flying wire in the crimping area;

• 
  

• The depth of the extrusion groove is not more than 0.3mm;

• 
  

• The length of the material belt is not more than 0.1～0.5mm;

• 
  

• The terminal bends up and down, left and right, not more than 5 º;

• 
  

• The terminal twist is not more than 15 º.

Product quality should be controlled from the source. There are many reasons that affect the quality of crimped terminals. As long as the terminal wire processing manufacturer takes precautions in advance, pay attention to crimping terminal specifications and shape requirements, tensile test standards, and connection specifications between terminals and connectors.
