When the fish-eye terminal is electrically connected with the female terminal, the resistance generated between the fish-eye terminal and the female terminal is called a contact resistance, the size of the contact resistance is directly related to the contact condition (such as contact area, contact pressure and oxidation degree of the contact surface) between the conductors and the material of the conductors, and the contact resistance is too large to generate a lot of adverse effects on the circuit. First, it causes an increase in power loss of the circuit. When current passes through the contact resistance, heat is generated, which can cause increased power loss from the circuit, affecting the efficiency of the circuit. The stability of the circuit is also reduced due to the excessive contact resistance, and when the contact resistance is excessive, the voltage and current of the circuit are changed, thereby affecting the stability of the circuit. This is particularly the case in high frequency circuits, the simplest way to reduce contact resistance is to increase the contact area;
the structure of the existing fish-eye terminal sequentially comprises a base part, two elastic parts connected with the base part and pin parts connected with the two elastic parts; the elastic parts are arc-shaped, the two elastic parts are arranged in opposite directions, a fish eye hole is formed between the two elastic parts, and a contraction space is provided for the two elastic parts through the fish eye hole; based on the existing design, only the plug-in part is electrically connected with the two elastic parts and the female terminal; increasing the contact area of the contact elastic portion inevitably reduces the elasticity of the elastic portion, affecting its normal use.
