This mechanical device applies precise pressure to a metal sleeve or terminal, crushing it onto a conductor. The resulting cold weld ensures low electrical resistance and high mechanical pull-out strength without requiring solder. Ratcheting versions prevent the jaws from opening until the full required pressure is reached, guaranteeing a reliable connection.
