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

technical field [0001] 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 [0002] 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 the attached figure 1 ), so this kind of coil package is a non-detachable whole, and the parts in the coil package cannot be disassembled and taken out without destroying the coil package, so there is a problem, when a certain part in the solenoid valve coil package ( For example, when the electromagnetic coil, armature, insert, diode, etc.) are damaged, the damaged parts cannot be repaired or replaced, but the entire electromagnetic valve must be replaced, which causes waste and increases the economic burden on the user. And because the insert seat cannot be replaced, and because some...

Problems solved by technology

[0002] 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 the attached figure 1 ), so this kind of coil package is a non-detachable whole, and the parts in the coil package cannot be disassembled and taken out without destroying the coil package, so there is a problem, when a certain part in the solenoid valve coil package ( For example, when the solenoid coil, armature, insert, diode, etc.) are damaged, the damaged parts cannot be repaired or replaced, but the entire solenoid valve must be replaced, which causes waste and increases the economic burden on the user.

And because the insert seat cannot be replaced, and because some inserts on the insert seat are single-insert, two-insert, and three-insert, it is necessary to equip different types of coil packs. When the user needs two-insert inserts, it must be Assemble and inject the coil package of the two-insert inserts, 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. Pressure, and because the coil package of the solenoid valve is one-time injection molding, 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 is also It makes the user shorten the service life of the entire solenoid valve
