Description

Technical Field

[0001] This utility model relates to the field of new terminal blade technology, specifically a new type of terminal blade. Background Technology

[0002] Terminal crimping blades play a crucial role in wire processing. They press the metal terminals onto the wire ends to establish conductivity. The working principles of terminal crimping blades include stepper motor operation and servo-controlled silent operation. Stepper motor operation uses a continuously rotating motor driven by an internal circuit breaker; while servo-controlled silent terminal crimping machines use a servo motor to transmit information to the motor, generating the action. In automotive manufacturing, electrical appliance manufacturing, and industrial automation, terminal crimping blades are used to connect and adjust wires and cables. Due to the need to handle more diverse, larger-scale, and more complex wires and cables, the precision, durability, and reliability requirements for terminal crimping blades are even higher.

The lower outer blade is engaged with the surface of the fixing mechanism. The front side of the lower inner blade contacts the rear side of the lower outer blade.

[0004] Although it achieves the functionality of setting up an upper inner blade, a lower inner blade, an upper outer blade, a knob, a fixing mechanism, and a lower outer blade, during use, the upper outer blade moves in front of the upper inner blade to move it to a fixed position. Then, the knob is rotated on the inner wall of the upper outer blade and the upper inner blade to fix the upper outer blade in front of the upper inner blade, avoiding misalignment of the upper outer blade and the upper inner blade during installation, making installation relatively convenient and quick. Next, the lower inner blade is snapped onto the surface of the fixing mechanism, and then the lower outer blade is snapped onto the surface of the fixing mechanism to restrict the position of the lower inner blade and the lower outer blade, facilitating subsequent installation work and making it convenient for users to use;

[0005] However, this does not solve the problem that the existing new type of terminal blade is generally not convenient to replace, which affects the convenience of replacing the blade and the convenient rotation of the blade for stamping terminals, thus affecting the convenience of stamping terminals.
