Problems solved by technology

[0002] In the production of traditional relays, the coil frame is an indispensable part of the electromagnetic relay. The winding assembly is formed after the coil frame is wound with enameled wire and the corresponding plug-in chip is assembled. The original coil frame structure starts from a section when winding. When it is exposed on the end face of the coil frame, the thread needle constantly collides with the end face and the starting line every time the wire is routed, there is a certain risk of damaging the paint layer, and due to the accumulation of tolerances, the flatness of the winding coil surface is reduced. In addition, it is used for enameled wire Pulling from the upper end of the coil frame to the plug-in chip, it will be damaged by the impact force of the plastic injection during the overmolding

Abstract

The present invention discloses a wire winding device of a relay. The wire winding device of the relay comprises a mounting base; the mounting base is provided with a wire winding assembly; the wire winding assembly comprises a wire winding groove and a coil lead-out sheet; and the coil lead-out sheet is arranged in the wire winding groove. According to the wire winding device of the relay, the rear end of the mounting base is provided with the wire winding groove; a coil lead-out sheet positioning hole is formed at the bottom of the wire winding groove; one end of the coil lead-out sheet passes through the coil lead-out sheet positioning hole and enters the wire winding groove; an enameled wire sleeves and is wound on a coil frame; two ends of the coil are connected with the coil lead-out sheet in the wire winding groove through an initial groove and an end groove respectively; and therefore, wire wound ends will not be exposed and damaged.

Description

technical field [0001] The invention relates to a relay component, in particular to a relay winding device. Background technique [0002] In the production of traditional relays, the coil frame is an indispensable part of the electromagnetic relay. The winding assembly is formed after the coil frame is wound with enameled wire and the corresponding plug-in chip is assembled. The original coil frame structure starts from a section when winding. When it is exposed on the end face of the coil frame, the thread needle constantly collides with the end face and the starting line every time the wire is routed, there is a certain risk of damaging the paint layer, and due to the accumulation of tolerances, the flatness of the winding coil surface is reduced. In addition, it is used for enameled wire Pulling from the upper end of the bobbin to the insert chip, it will be damaged by the impact force during plastic injection molding during overmolding.
