1.1 Structural Design Issues
The structural design of the connector related to the terminal holding force mainly refers to the design of the hooking structure of the terminal and the sheath. This hooking structure is generally an elastic structure, which can be divided into the elastic structure used on the sheath and the elastic structure used on the terminal.
1.1.1 Elastic structure is adopted on the sheath
The elastic structure of the sheath is shown in Figure 1. The elastic structure on the sheath means that the elastic structure required for the assembly of the terminal and the sheath is designed on the sheath. During the assembly process of the terminal and the sheath, the spring tongue (the elastic structure designed on the sheath) is supported Force deformation to realize the assembly of the terminal and the sheath. After the terminal and the sheath are assembled in place, the sheath spring returns to its original state due to the release of the force. The sheath elastic tongue cooperates with the hanger structure designed on the terminal to ensure the effective positioning of the sheath to the terminal. The shear strength of the boot spring determines the retention of the terminal in the boot. The formula for calculating shear stress is as follows:
In the formula: τ——the shear stress of the material; F——the force in the shear direction of the material; A——the shear area; [τ]——the allowable yield shear stress of the material.
From the formula (1), it can be seen that the maximum force in the shear direction of the material is proportional to the shear area of the material and proportional to the allowable shear stress of the material. When designing the sheath spring tongue, when the material is selected, the allowable yield shear stress of the material is fixed. To ensure that the product meets the requirements of the retention force (force in the shear direction) of the terminal in the sheath, it is necessary to ensure that the sheath The shear area of the elastic tongue meets the required value. In practice, due to consideration of the design gap between the terminal and the sheath, the shear area should be calculated according to the extreme worst case. The design gap between the terminal and the sheath should be able to ensure that the calculated shear area can withstand the yield shear stress greater than the required holding force of the terminal in the sheath under extreme severe conditions.
