[0002] Solenoid valves are commonly used control devices in the field of gas, liquid and other flow channels. They are widely used, such as controlling the flow direction of media in heat exchange systems. They are important components in equipment such as air conditioners and water heaters. Solenoid valves are mainly composed of an electromagnetic coil, a magnetic core and a valve body. When the electromagnetic coil is energized or de-energized, the movement of the magnetic core will cause the fluid to pass through the valve body or be cut off, so as to achieve the purpose of changing the direction of the fluid.

[0003] In the prior art, the coil components of the solenoid valve generally include a coil frame and enameled wires. The enameled wires are wound around the coil frame, and positive and negative leads are led out for connection with electrical plug-ins or external wires. However, the wire installation of the existing solenoid valve coil is too cumbersome, and the joints are prone to loosening, resulting in poor contact effect, which may affect the stability of the solenoid valve operation.

[0004] Therefore, it is necessary to provide a new type of solenoid valve coil to solve the above problems. Utility Model Content

[0022] By setting the above-mentioned structure, after the enameled wire 2 is wound on the coil skeleton 1, the two ends of the enameled wire 2 can be placed on the positioning piece 8 on the end face of the coil skeleton 1, and the pressure plate 4 on the sliding extension part 3 can be used to make the wire pressing piece 7 cooperate with the positioning piece 8 to limit the positioning of the positive lead 5 and the negative lead 6. The wires that need to be connected to the positive lead 5 and the negative lead 6 can also be clamped here to complete a stable connection. If a welding connection is to be performed, the cooperation between the wire pressing piece 7 and the positioning piece 8 can shield the welding point while clamping it to ensure the stability of the connection at the welding point, thereby improving the connection effect between the positive lead 5, the negative lead 6 and the wire, and avoiding affecting the stability of the solenoid valve.

[0025] By setting the above structure, the positive lead 5 and the negative lead 6 at both ends of the enameled wire 2 can first pass through the positioning groove 14, and then enter the wire accommodating groove 11 between the fixing ring 10 and the end face of the coil skeleton 1, and can be wound in the wire accommodating groove 11 for a certain number of turns before entering the groove 13 on the positioning member 8. In this way, the positive lead 5 and the negative lead 6 can be effectively fixed after extending from between the two end faces of the coil skeleton 1, which is convenient for welding with external wires. The embedded groove 12 that accommodates the positioning member 8 allows the positive lead 5 and the negative lead 6 to enter the groove 13 from the wire accommodating groove 11 more smoothly. In order to achieve a stable clamping and fixing effect, the positive lead and the negative lead 6 can be repeatedly folded in the groove 13 for many times.
