Problems solved by technology

However, the electromagnetic coils of the existing structure, including the patent document JP-9-106911, neither relate to the setting of the variable resistance device nor how to reasonably place the variable resistance device so that the electric element positioning structure of the electromagnetic coil can fully Play a role; further, because of the increase in electrical components and functions, the resulting heat should affect the winding as little as possible, and at the same time, the heat generated by the winding when energized should affect the electrical components as little as possible

Embodiment Construction

[0042] FIG. 1 is a perspective view of a bobbin 1 of an electromagnetic coil according to an embodiment of the present invention.

[0043] The bobbin 1 is composed of a winding core 2 and collar portions 2a and 2b.

[0044] The winding core 2 is in the shape of a hollow circular cylinder, and the symbols 2a and 2b are a pair of flange-shaped parts opposite to and parallel to each other at both ends of the winding core 2 . The winding core 2 and the flange parts 2a and 2b are integrally formed by synthetic resin, such as injection molding, and the resin material is such as polybutylene terephthalate.

[0045] In the frame 1, one flange-shaped portion 2a is hollow and approximately disk-shaped, and has an outer peripheral surface 2a1, and a plate-shaped approximately square extension portion 2a2 protrudes from the peripheral surface 2a1. The extension portion 2a2 has a front end surface 2a3, an upper surface 2a6, a side surface 2a7, and a side surface 2a8. The collar portion 2...

Abstract

A positioning structure of electric element on electromagnetic coil is featured as positioning lead wire by inserting lead wire in groove-fixing hole when lead wire is contacted with winding for effectively preventing lead wire from shift when seal is applied with synthetic resin in order not only to make reliable seal and fixture on winding and lead wire internal end but also to obtain compact structure of electric elements on electromagnetic coil.

Description

technical field [0001] The present invention relates to the electric element positioning structure of the electromagnetic control valve, the electromagnetic solenoid or the electromagnetic coil of the four-way switching valve used in the refrigeration cycle, especially related to the placement of the components connected with the coil and the electrical elements. Background technique [0002] The positioning structure of the electrical components of the electromagnetic control valve, electromagnetic solenoid used in the refrigeration cycle or the electromagnetic coil of the four-way switching valve used in the refrigeration cycle is to convert the electric power into the working state of the magnetic force conversion valve, and the working state of the valve The change may be the change of the limit position, such as the opening or closing of the medium circulation pipeline, or it may be the maintenance degree of a working state, such as the opening si...
