AI Technical Summary

Technical Problem

The connection between the lead wire and the detonator body of the existing electronic detonator lacks a positioning device, which makes it easy to loosen after insertion, affecting the test accuracy.

Method used

Design an electronic detonator lead wire clamp positioning device, including a housing, a cover, a sealing plate, and an adjustment mechanism. The plug and socket are clamped and positioned by a clamping rod and a limiting part, and sealed by the housing and cover to prevent external impurities from entering.

Benefits of technology

It achieves a stable connection between the plug and socket, improves testing accuracy, and ensures the sealing of the connection to prevent external impurities from affecting its use.
