Design of connector terminals in automotive connectors

The use of automotive Connectors is mainly in the automotive industry, and we should be generally familiar with the design of connector terminals. There are many situations where car connectors are used now, and the design should be more user-friendly. Below, Kangrui connector manufacturer will talk to you about the design of connector terminals in automotive connectors.
In the process of connector terminal design, product standards play a guiding role, and almost all factors are based on them. The selection of materials will play a crucial role in the performance of the product, which is also a key point in the design process. Taking plastic materials as an example, if they are used as raw materials for connector terminals, it is necessary to test whether their technical parameters can meet the requirements of the product, such as voltage resistance, impact resistance, and aging resistance.
As for the selection of hardware materials, pressing is the main method. Because opium can meet both conductivity and a certain degree of elasticity, it is often difficult to choose materials in the design of connector terminals. This is precisely a trend pursued by manufacturers in elastic components, and many hardware manufacturers are working towards this direction. The conductivity of materials can affect the temperature rise and resistance elasticity of connector terminals, which are related to the material's elastic modulus, chemical properties, tensile strength, and hardness.
The selection of elastic modulus is calculated by the theoretical formula of material mechanics. The higher the conductivity of the material, the smaller the contact resistance, and the lower the temperature rise. The relationship between insertion and extraction force and contact resistance is a quadratic relationship. Contact resistance is mainly divided into compression resistance, thin film resistance, and volume resistance (the resistance of the conductor itself). Among them, membrane resistance accounts for 70-80% of the total resistance and is also the main factor affecting the lifespan of connectors, which should be given full attention.
