Abstract

An electromagnetic coil includes a winding core and a pair of jaw-like portions which are arrange at two ends of the winding core and are in parallel, thereby a winding portion of a winding is formed between the jaw-like portions, a lead is connected to the winding, the winding is envelopped by a synthetic resin which at least envelops the lead portion; the coil is characterised in that each jaw-like portion includes an arc-like portion and projecting portions extending from the arc-like portion to a side, wherein one projecting portion is provided with a positioning structure for positioning the lead. In the electromagnetic coil with this structure, when the lead is contacted with electrical members such as the winding and the like, movement of the lead when sealing the synthetic resin can be effectively prevented because the lead can be positioned by the positioning structure provided on the projecting portion, the winding and an inner end of the lead can be reliably sealed and fixed, and an electromagnetic coil with electrical members provided compactly can be obtained.

Description

technical field

[0001] The present invention relates to an electromagnetic control valve, an electromagnetic solenoid or an electromagnetic coil of a four-way switch valve for a refrigeration cycle, particularly relating to the placement of components and electrical components connected to the coil. Background technique

[0002] Electromagnetic control valves, electromagnetic solenoids for refrigeration cycles, or electromagnetic coils for four-way switching valves for refrigeration cycles are used to convert electric power into magnetic force to change the working state of the valve, and the change of the working state of the valve may be the limit position Changes, such as the opening or closing of the medium circulation pipeline, may also be the degree of maintenance of a working state, such as the size of the opening of the medium circulation pipeline.

[0003] A common electromagnetic coil includes a winding core and a pair of flange-shaped parts...
