Operators Of Cold-press Needle Crimping Machines Must Follow Proper Procedures During Crimping Operations.

In electrical connection operations, the contact crimper is a precision crimping device, and its operational quality is directly related to the reliability of the connection and production safety. Operators must have a clear understanding of the equipment's performance and process requirements when using the d sub contact crimper.

Pre-operation equipment checks are essential. These checks include ensuring the pneumatic system is stable within the 0.4-0.6 MPa range, checking for wear on the crimping die, and verifying the compatibility of the wire and terminal specifications. The wire stripping length must be precisely controlled according to the terminal conductor cylinder size, typically the cylinder length plus 1 mm. Stripping tools should be kept sharp to prevent damage to the wire core. When placing the terminal in the contact crimping  lower die, proper alignment is crucial; misalignment may cause deformation of the crimping area or insulation entering the crimping cylinder.
