Description

Parallel wire clamp with replaceable mouth mask

The present invention relates to the field of micro terminal crimping tools, in particular to a parallel crimping plier with replaceable mouth mask.

The crimping film and the clamping part of the existing micro-terminal crimping clamp are fixedly connected, and the crimping film cannot be replaced. It can only meet the wiring requirements of a single size and cannot be used for crimping terminals of different specifications. Therefore, crimping clamps with replaceable crimping dies have gradually appeared on the market. Most of the replacement methods use screws for fixed installation. The connection block on the side of the crimping die is inserted into the inside of the crimping clamp, and the crimping film is fixed with bolts. The replacement steps of this type of crimping clamp are slow and complicated.

Furthermore, most crimping tools for micro terminals use jaw rotation and crimping to crimp the crimping terminals. However, the rotation and crimping method can easily cause asymmetry on both sides of the terminal after crimping, and the terminal near the fulcrum position. It will be crimped tighter and deformed, making it impossible to put it into the plastic box and cannot be used, affecting the process yield and increasing manufacturing costs.

The main purpose of the invention is to provide a parallel crimping clamp with replaceable mouth film, which can not only quickly replace the mouth film, but also use the upper and lower parallel crimping method to crimp the micro terminals, improving the defect that the micro terminals are easily damaged due to the use of the rotary crimping method.

In order to achieve the above objects and effects, the present invention proposes a parallel crimping plier with a replaceable oral film, which includes: a film pressing component having a film pressing part, and the film pressing part has an internal space, a film pressing opening, and a film pressing opening. There is a fixed handle provided below the laminating part and a movable handle pivotally connected to the internal space of the laminating part. The movable handle can pivot repeatedly in the direction of the fixed grip. A crimping component, which has an upper crimping part and a lower crimping part. The upper crimping part is arranged in the internal space of the lamination part and is fixed above the lamination opening. The lower crimping part is disposed in the internal space of the lamination part. And the activity is located below the lamination opening. A film assembly is provided at the film opening of the film pressing part and is clamped between the upper and lower pressing parts. A pivot swing piece is located in the internal space of the lamination part. The two ends of the pivot piece are respectively pivoted to the movable handle and the lower pressing piece. When the movable handle pivots, it drives the two ends of the pivot piece to pivot upward and downward, thereby driving the The lower crimping piece moves up and down. A film-retracting component has a film-removing member. The film-removing member is located in the internal space of the film-pressing part.
