AI Technical Summary

Technical Problem

The connection stability between the coil and the pin in the existing bakelite frame is poor, and the flying wire is easy to fall off, especially under long-term vibration or external force.

Method used

The pins are welded to the fixed plate or integrally formed. The pressure plate is sleeved on the outside of the pin and spot welded below to form a limiting block. The lead wire is clamped by the cooperation of the fixed plate and the pressure plate. The contact area between the lead wire and the pin can be bent into a U or ring shape to increase the connection strength. Tin-plated copper material is used to improve conductivity and oxidation resistance.

Benefits of technology

It improves the connection stability between the coil and the pin, reduces the phenomenon of lead wires falling off, enhances the connection strength, and reduces production costs.

Abstract

The utility model discloses a higher anticorrosive bakelite framework relates to electronic components technical field, the utility model discloses a framework main part, and the both sides of framework main part bottom all are through the pin, and the pin outer part is respectively sleeved with fixed disc and pressure plate, and the pin one side is connected with the limit stop piece. The utility model discloses the setting of pin, fixed disc, pressure plate and limit stop piece, and the pin is fixed in the mould when phenolic resin powder integrated forming after welding or integrated forming with fixed disc, then the pressure plate is sleeved in the pin outside and is spot welded to form a welding spot below the pin one side, and the welding spot is outwardly convex and forms the limit stop piece and limits the pressure plate, avoids the limit stop piece and falls off, and the lead-out wire is welded with the pin and fixed disc after coil assembly is finished, then the pressure plate is moved and is welded to the fixed disc again, and the lead-out wire is welded and fixed through the cooperation of fixed disc and pressure plate and clamping, effectively increases the stability of the flying wire connection, thereby reduces the phenomenon of welding spot area and separates.
