Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromagnetic coil, concretely is an electromagnetic coil of integrated temperature detection function pin. BACKGROUND

[0002] Electromagnetic coil is widely applied in traditional industry and automobile industry, electromagnetic coil is the device that utilizes the principle of electromagnetic induction and works, and the basic structure is that the wire is wound on the insulating framework, electromagnetic coil uses the wire that generates the magnetic field of electrification, and the magnetic field generated by electrification and fixed magnetic field interact, thereby drive valve and other mechanical components, realize rotation or linear motion.

[0003] In addition to being widely used in traditional fields, in recent years, with the rapid development of hydrogen energy industry, electromagnetic coil has become a key functional element in hydrogen energy industry, and participates in various links of hydrogen energy, mainly in the form of electromagnetic valve assembly, plays an irreplaceable role, electromagnetic valve is a device that controls the opening and closing of the valve through the electromagnetic force generated by the electrification of the electromagnetic coil. It has the characteristics of fast response speed, high control precision, etc. The electromagnetic valve generates electromagnetic force through the electromagnetic coil, so that the valve core moves up and down, thereby controlling the on-off of the fluid in the valve.

[0004] The internal medium of most of the valves used in hydrogen energy industry such as hydrogen vehicle end or hydrogen refueling station is hydrogen, which is highly dangerous, flammable and explosive, and has high technical requirements for product research and development and production. In actual use, especially in the field of vehicles, in order to ensure the safety of the medium, a temperature sensor is usually provided on the valve body of the electromagnetic valve to detect the temperature of the medium. For example, in the case of a valve at the end of a vehicle hydrogen cylinder, during refueling, the internal medium of the hydrogen cylinder will rapidly heat up. When the detected medium temperature is too high, the valve is closed, the hydrogen gas source medium is cut off, and refueling is stopped to protect the hydrogen cylinder from being damaged by the high medium temperature. During gas use, the internal medium of the hydrogen cylinder will rapidly cool down. When the detected medium temperature is too low, the valve is closed, the hydrogen gas source medium is cut off, and gas use is stopped to protect the hydrogen cylinder from being deformed due to the low medium temperature, causing hydrogen leakage and other safety accidents. Valve body temperature monitoring is a necessary functional requirement. The traditional electromagnetic coil scheme does not integrate the temperature detection function pin, and in actual application, an additional temperature sensor collection pin needs to be installed on the valve body and connected to the controller end for temperature signal collection. The integration degree is low, and the waterproof sealing of the new temperature sensor lead wire needs to be considered, which increases the complexity of the electromagnetic valve coil base and is not conducive to mass production.

[0023] Please refer to Figures 1-3 The present application provides a technical scheme: an electromagnetic coil with integrated temperature detection function pins, comprising: an enameled wire winding 3, a bearing support assembly, an injection shell 4 and a temperature sensor plug-in 6.

[0026] Insulating skeleton 5: made of corrosion-resistant material with certain strength and good insulation, used to provide support base for winding and fixing the enameled wire winding 3.

[0027] Injection shell 4: after the coil inside the body assembly is completed, a mold is made according to the overall shape of the coil, and a material with good flowability and good insulation is used to mold the entire coil by injection molding process to form a coil shell body required by the mold.

In order to prevent the copper wire winding from being short-circuited between turns, an insulating paint is coated on the surface of the copper wire before winding. Therefore, after the copper wire coated with insulating paint is wound on the insulating skeleton, the enameled wire winding is formed. The two ends of the winding are reserved with pins.
