AI Technical Summary

Technical Problem

Traditional piezoelectric ceramic polarization devices are prone to poor soldering or detachment at high-temperature environments, resulting in poor contact between the negative resistor pin and the spring pin sleeve, affecting the polarization process, producing defective and scrap products, and making inspection difficult.

Method used

The conductive spring pin is fixed to the negative electrode pin of the resistor by using irregularly shaped mounting holes and interference fit. This improved connection method is a compression connection, which avoids the influence of high temperature and ensures reliable contact.

Benefits of technology

This achieves a reliable connection between the resistor and the conductive spring pin, avoiding poor contact problems caused by unstable welding, improving assembly efficiency and ease of inspection, and reducing the defect rate.

Abstract

The utility model relates to a piezoelectric ceramic sheet polarization device. This piezoelectric ceramic sheet polarization device adopts the special-shaped mounting hole of gourd shape structure, the metal sleeve of conductive spring needle is fixed in the big circle hole according to the interference fit mode, the resistance negative pole pin is fixed in the small circle hole according to the interference fit mode, solves the problem that the high temperature environment easily makes the welding point melt and forms the false welding or the welding separation, causes the sleeve of resistance negative pole pin and spring needle to separate contact or contact badly, thereby leads to the piezoelectric ceramic sheet in the polarization process not normal electrification, influences the electric performance parameter of piezoelectric ceramic sheet product, produces the substandard product, waste product, in order to avoid above situation, must often utilize the instrument (such as multimeter) to detect the electrification situation of each resistance on the clamp one by one, not only the labor intensity is big, the efficiency is low, and still easy to miss, in addition, if the welding point melts and forms the false welding, even if utilizing the instrument also has difficult to find etc.
