Terminal crimping standards and inspection specification requirements

Terminal crimping standards and inspection specifications are important components of electronic circuits, widely used in fields such as electrical, communication, power distribution, automation, aerospace engineering, etc. In order to maintain the normal use and life safety of equipment, it is particularly important to develop terminal crimping standards and inspection specifications. This article will introduce the main content of terminal crimping standards and inspection specifications, facilitating readers to better understand and master relevant knowledge.

1、 Terminal crimping specifications

Terminal Material Regulations

When crimping terminals, appropriate terminal materials need to be used. Common terminal materials include copper, aluminum, stainless steel, etc. Among them, the copper end has high conductivity and corrosion resistance, suitable for environments such as wet and cold, corrosion, etc. The aluminum end is lightweight and suitable for high-frequency circuits. The stainless steel end has high strength and corrosion resistance, suitable for long-term operation of circuits.

Terminal specifications

The size of the terminal must meet the design requirements. If the terminal specifications do not meet the requirements, it will lead to poor circuit connection and affect the reliability and stability of the power supply.

Terminal surface quality regulations

The surface of the terminal must be smooth and free from defects such as scratches and spots. Otherwise, the conductivity and Contact force of the terminal will be affected, resulting in poor circuit connection.

Specify terminal crimping force

When crimping terminals, strength must be mastered. If the strength is too high, it can cause terminal deformation, affecting the reliability and stability of circuit connections. If the strength is too small, it can lead to issues such as loose terminal connections and short circuits.

2、 Terminal Inspection Specification

Visual inspection is the first step in terminal verification. The inspector must carefully inspect the surface and specifications of the terminal to ensure that there are no defects on the surface and that the specifications comply with regulations.

Conductivity inspection Conductivity detection is an important component of terminal detection. Inspectors need to use professional conductivity testing equipment to detect the conductivity of terminals to ensure normal circuit connections.

Contact force inspection Contact inspection is the third step of terminal verification. Inspectors need to use professional contact testing equipment to test the connection force of terminals to ensure that the connection force meets the requirements.

The withstand voltage test is the final step of terminal verification. The inspector needs to connect the terminal to the circuit and apply a certain voltage to test the compressive strength of the power supply to ensure the safety and reliability of the circuit connection.
