I. Overview of Cold-Pressed Terminals

Cold-pressed terminals are common accessories in electrical connections. They tightly bond wires and terminals through a cold-pressing process to achieve effective electrical conduction. Widely used in various electronic devices, automotive electronic systems and other fields, these terminals are widely recognized in the industry for their efficiency, stability and safety.

II. Preparation Before Use

efore using cold-pressed terminals, ensure the power supply is disconnected to avoid potential electric shock hazards. Next, prepare necessary tools such as wire strippers, insulation strippers and crimping pliers, which will help complete the wiring work more effectively.

III. Usage Steps of Cold-Pressed Terminals

1. Strip the wire insulation: Use wire strippers or insulation strippers to strip a section of the wire insulation, usually 5-10 millimeters. The purpose of this step is to expose the metal conductor of the wire for connection with the terminal. 

2. Insert the wire: Insert the stripped wire into the cold-pressed terminal, ensuring the wire fully enters the terminal interior with an appropriate insertion depth. To prevent the wire from loosening inside the terminal, gently hold the terminal with your fingers for fixation.

3. Crimp with crimping pliers: Select a suitable crimping plier and crimp the cold-pressed terminal. During crimping, ensure the plier applies moderate force—avoid excessive or insufficient force that may damage the terminal or cause poor contact. After crimping, the terminal should be tightly bonded to the wire with no gaps.

IV. Special Usage Notes for Ring-Type Cold-Pressed Terminals

As a special type of cold-pressed terminal, ring-type cold-pressed terminals have a similar usage method to ordinary terminals but require the following special precautions:

1. Select the appropriate terminal specification: Choose the correct ring terminal specification based on the wire diameter and the current it needs to carry. Ensure parameters such as terminal diameter and wire slot width match the wire.

2. Match the fixing hole diameter: Ring terminals are usually equipped with fixing holes for securing the terminal to equipment or connectors. When selecting fixing screws, ensure their diameter matches the fixing hole to ensure the terminal is firmly secured.

V. Safety Inspection and Testing

After completing the connection of cold-pressed terminals, conduct safety inspection and testing without fail. First, check for gaps or loosening between the terminal and the wire to ensure a tight and reliable connection. Second, inspect for exposed metal conductors around the terminal to prevent electric shock risks. Finally, reconnect the power supply and test if the wiring works normally.
