Self-adjusting crimping pliers

Abstract

The invention relates to a self-adjusted wire crimper. The self-adjusted wire crimper comprises a crimper head and a driving mechanism. The crimper head comprises a plurality of pressing teeth, a gear ring, a rotating plate and supporting plates. The pressing teeth are evenly arranged in the gear ring. The rotating plate is arranged two sides of the pressing teeth and two sides of the gear ring. The pressing teeth are in linkage matching with the rotating plate and the gear ring at the same time. A leaf spring is integrally formed on the rotating plate. The two supporting plates are correspondingly connected to the driving mechanism. The rotating plate is connected to the inner side of each supporting plate to form rotating matching. Both the leaf spring and the gear ring are in linkage with the driving mechanism. Because the rotating plate and the leaf spring are integrally formed, when different diameters of terminals are connected in a pressed mode, elastic deformation of the leaf spring is generated so that the pressing connection motion can be completed, and the self-adaption purpose is achieved; furthermore, because the rotating plate and the gear ring are arranged in the supporting plates and are in linkage with the driving mechanism, the rotating radian of a single component is reduced through the relative motion of the rotating plate and the gear ring, and the driving travel of the driving mechanism is reduced.

Description

technical field [0001] The invention relates to a wire crimping pliers, in particular to a self-adjusting wire crimping pliers for crimping bushing type terminals. Background technique [0002] Crimping pliers are tools used to crimp terminals and wires. Different crimping pliers are selected for crimping according to different terminals. Existing crimping pliers for crimping tubular terminals generally do not have a self-adjusting function, and need to be adjusted according to the size of the terminal before crimping. The operation is cumbersome, the applicable area is narrow, and it is not universal. [0003] The existing crimping pliers capable of self-adjustment are generally manually operated manual pliers. This kind of crimping pliers requires a very long reed, and one of the handles of the manual pliers needs to be used as an action handle instead of a reed. The reed can only be set in the fixed handle. In order to ensure the elasticity of the reed and the pressure w...

Problems solved by technology

The existing crimping pliers for crimping tubular terminals generally do not have the function of self-adjustment, and need to adjust the size according to the size of the terminal before crimping. The operation is cumbersome, the applicable area is narrow, and it does not have universality.

[0003] The existing crimping pliers capable of self-adjustment are generally manually operated manual pliers. This kind of crimping pliers requires a very long reed, and one of the handles of the manual pliers needs to be used as an action handle instead of a reed. The reed can only be set in the fixed handle. In order to ensure the elasticity of the reed and the pressure when crimping the wire, the reed needs to be very long. If this kind of pliers is to be added to the pneumatic or electric pliers, then There will be a lack of space to accommodate the reed, so there are no self-adjusting pneumatic or electric pliers on the market today

Manual pliers have certain requirements for physical strength when used many times, especially in wire harness processing and terminal crimping production enterprises. Workers need to use manual pliers for a long time, which is labor intensive and affects production efficiency.
