Problems solved by technology

However, for the solenoid valve used in automobiles, it is required to have high service life and stability requirements, and to be able to maintain stability under vibration, high temperature or low temperature environment, especially the electromagnetic coil in the solenoid valve must be stable, the reason is that the vehicle In the process of forming, vibration and bumps will occur. If the electromagnetic coil generates large vibration or structural damage when the vehicle is bumping, this may cause the magnetic parts installed at the end of the electromagnetic coil to be unable to magnetize when the electromagnetic coil is energized. , so that the solenoid valve cannot be used normally

The electromagnetic coil assembly comprises an electromagnetic coil component and an installation component, the electromagnetic coil component comprises an electromagnetic coil and a plastic-coated part, the plastic-coated part is provided with a plastic-coated main body and at least one limiting structure, the electromagnetic coil is wrapped by the plastic-coated part, the limiting structures are formed on the plastic-coated part, the installation component forms an installation space, and the plastic-coated main body is pressed against the installation space of the installation component in an interference fit manner by means of the limiting structures.

Description

technical field [0001] The invention relates to an electromagnetic coil, in particular to an electromagnetic coil assembly. Background technique [0002] At present, the electromagnetic coil assembly includes an electromagnetic coil, wherein the current in the electromagnetic coil is switched on and off, so that the magnetic part at the end of the electromagnetic coil can be switched between two different states of magnetization and demagnetization. [0003] Based on the characteristics of the electromagnetic coil assembly, the electromagnetic coil assembly is widely used in relays and solenoid valves. Especially in the solenoid valve, the on-off of the current in the electromagnetic coil of the electromagnetic coil assembly can control the on-off of the electromagnetic valve, and then control the channels of the pipelines arranged on both sides of the electromagnetic valve, thereby controlling the on-off of the fluid. [0004] Solenoid valves are widely used in vehicles, e...
