Precautions for the crimping process
From the point of view of the manufacturing process, three things need to be done: neat terminal feeding, level terminal placement, and alignment of mold jaws The orderly feeding of terminals means that when feeding, it is necessary to ensure that the terminals do not collide with the surrounding parts, so that the terminals can […]
Effect of Crimp Height on Terminal Electrical Performance
The contact between the terminal and the wire is not completely in contact, but scattered at some points on the contact surface. The difference between the actual contact area and the theoretical contact area may reach thousands of times. The resistance formed by the contact between conductor and conductor is called contact resistance, which is […]
Performance comparison of different wires
1. Ordinary wire Regular wire is usually made of many strands of thin copper wire. The multi-strand form has good bending resistance and is not easy to break due to repeated vibrations. Common conductors consist of two parts: a copper core and insulating material. Polyvinyl chloride material is usually used for insulation and has the […]
How to choose the wire?
Wire is an important part of terminal crimping, and the main factors to consider when selecting wire are conductor material, insulation material, and ampacity. 01 conductor material In the case of the same wire diameter, the current carrying capacity of the copper wire is greater than that of the aluminum wire, but the weight of […]
Effect of Crimp Height on Mechanical Properties of Terminals
The tensile strength of the terminal mainly depends on the contact pressure between the terminal and the wire. The contact pressure is mainly provided by the elastic deformation and plastic deformation of the terminal and the wire. An important factor that determines the elastic deformation and plastic deformation of the terminal and the wire is […]
What is the difference between different plating materials of terminals？
Electroplating on the surface of the terminal is a technical method to solve the oxidation and corrosion of the metal on the surface of the terminal, enhance the conductivity of the terminal, and reduce the contact resistance. Besides gold, silver, and nickel or chrome plating, tin plating is most commonly used in terminal plating. Gold […]
How to choose terminal material?
When selecting a terminal material, the following characteristics should be considered: ① Mechanical properties of materials. Strength, ductility, yield strength, hardness, etc. ②Electrical conductivity and thermal conductivity of the material. The electrical conductivity is directly proportional to the thermal conductivity, the thermal conductivity is related to the electrical conductivity of the terminal and its own […]
Environmental Performance of Connectors
① Temperature resistance: At present, the maximum working temperature of the connector is 200°C (except for a few high-temperature special connectors), and the minimum temperature is -65°C. When the connector is working, the current generates heat at the contact point, causing the temperature to rise. Therefore, it is generally believed that the working temperature should […]
Electrical performance of the connector
The main electrical properties of connectors include contact resistance, insulation resistance and electric strength. ① Contact resistance: High-quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms. ②Insulation resistance: It is an index to measure the insulation performance between the […]
Mechanical Properties of Connectors
As far as the connection function is concerned, the mating force is an important mechanical property. The insertion force is divided into insertion force and pull-out force (pull-out force is also called separation force), and their requirements are different. There are regulations on the maximum insertion force and the minimum separation force in the relevant […]
