Electromagnetic valve

Abstract

The invention discloses improvement and invention of an electromagnetic valve. The invention comprises a valve body and a coil package, wherein the coil package comprises a housing, an exhaust hood and a plurality of parts which are arranged in the housing to constitute the electromagnetic valve, such as a coil, a plug and a diode and so on, wherein the coil and the diode are arranged on a connector assembly which is characterized in that the connector assembly is embedded on housing wall and a heat dissipating chamber is arranged between the connector assembly and the coil. The coil of the invention does not need cast processing and a heat dissipating chamber is arranged between the connector assembly and the coil, thereby heat dissipation performance of the coil and the diode is effectively improved and the stability and durability of the quality of the products are improved.

Description

a solenoid valve technical field The present invention relates to an improved invention of a solenoid valve, in particular to an improved invention of a solenoid valve used in motor vehicles. Background technique At present, solenoid valves are widely used in various production fields. The coil packages of existing solenoid valves are all made of plastic injection molding at one time (refer to Figure 1). Therefore, this kind of coil package is a non-detachable whole. Under the premise of the package, the parts in the coil package cannot be disassembled and taken out, so there is a problem that when a certain part in the solenoid valve coil package (such as electromagnetic coil, armature, plug, diode, etc.) is damaged, it cannot be aimed at. Instead of repairing or replacing damaged parts, the entire solenoid valve must be replaced, which causes waste and increases the economic burden on the user. And because the plug seat cannot be replaced, because some plugs on the plug...

AI Technical Summary

Problems solved by technology

At present, solenoid valves are widely used in various production fields. The coil packages of existing solenoid valves are all made of plastic injection molding at one time (refer to Figure 1). Therefore, this kind of coil package is a non-detachable whole. Under the premise of the package, the parts in the coil package cannot be disassembled and taken out, so there is a problem that when a certain part in the solenoid valve coil package (such as electromagnetic coil, armature, plug, diode, etc.) is damaged, it cannot be aimed at. Instead of repairing or replacing damaged parts, the entire solenoid valve must be replaced, which causes waste and increases the economic burden on the user

And because the plug seat cannot be replaced, because some plugs on the plug seat are single-plug, two-plug, and three-plug, it is necessary to equip different types of coil packs. When the user needs a two-plug plug, it must be assembled and injected. The coil package for the plug, and the quantity must match the needs of the user, otherwise it will cause overstocking, and the shipment will not be delivered until the next time the user needs it, which will cause capital stagnation for the manufacturer, and due to the electromagnetic The coil package of the valve is one-time injection molding, so that the space between the diode and the coil is filled with plastic, which is affected by the heat dissipation performance of the plastic material, so the heat dissipation is extremely poor, and the coil and the diode are easily short-circuited, which also shortens the time for the user. The service life of the entire solenoid valve
