AI Technical Summary

Technical Problem

During the crimping process between the terminal and the wire, the complex shape and structure of the transition zone makes it difficult to form a complete closure of the tear opening, affecting the transmission capacity of the wire and making it susceptible to interference from external signals.

Method used

The combination structure of pressing die and elastic die is adopted. Through the pressing surface and guiding slope design of the pressing die, the opening of the pressing joint is gradually closed. Combined with the pre-pressing surface and elastic pressing, the stability of the pressing joint and signal transmission are ensured.

Benefits of technology

This achieves complete closure of the terminal and wire connection, improving the stability of signal transmission, avoiding external interference, and ensuring the reliability of the electrical connection.

Abstract

The application discloses a terminal crimping die module, which comprises a crimping die seat and at least one crimping die. The crimping die has an end face, which is recessed from the end face towards the middle part of the crimping die, and forms a crimping groove which is open to the outside of the crimping die and is used for placing a crimping joint of a terminal. The crimping die has a first surface and a second surface, which are arranged on both sides of the crimping groove along the length direction of the crimping groove, and the crimping groove penetrates through the first surface and the second surface. The height of the crimping groove bottom edge penetrating through the first surface is higher than that of the crimping groove bottom edge penetrating through the second surface. A crimping surface is formed between the crimping groove bottom edge of the first surface and the crimping groove bottom edge of the second surface. When external force is applied to the crimping die, the crimping surface crimps the crimping joint of the terminal, so that the opening of the crimping joint forms a closed state, the stability of signal transmission at the joint of the terminal and a wire is ensured, and the interference of external signals is avoided.
