Description

Technical Field

[0001] This utility model relates to the field of electromagnetic valve connector technology, specifically a small connector resistant to vibration and shock. Background Technology

[0002] A solenoid valve is an automated actuator that uses electromagnetic force to control the flow of fluid. It mainly consists of a solenoid coil, valve body, valve core, and return spring. When the coil is energized, it generates a magnetic field, driving the iron core to move the valve core and change the opening or closing state of the flow channel. When the power is off, the spring returns the valve core to its original position. This device is widely used in industrial automation, hydraulic and pneumatic systems, automotive manufacturing, and household appliances (such as washing machines and air conditioners), enabling precise control of the flow rate and direction of gases, liquids, and other media.

[0003] In hydraulic and pneumatic systems, solenoid valves need to be repeatedly energized and de-energized to change the flow direction of fluid in order to control hydraulic or pneumatic cylinders. However, when the flow direction changes, the fluid inside the connected pipeline vibrates, especially when the solenoid valve acts as an actuator in a pneumatic cylinder, where the vibration and impact are more pronounced. To resist vibration and impact, the connector of the solenoid valve is usually fixed to the solenoid valve by bolt connection. However, after long-term vibration, the bolt may rotate, which may cause the connector to loosen. At the same time, the connector often uses threaded posts to connect to the external power supply. Vibration can also cause the threaded posts to rotate, resulting in loosening of the connection position. Therefore, we propose a small connector that is resistant to vibration and impact.

The rear side of the base plate 41 is provided with cross-shaped retaining blocks 42 symmetrically distributed from left to right. The cross-shaped retaining blocks 42 are respectively inserted into the nuts of the adjacent threaded post 8 on the rear side (the nuts of the threaded post 8 are provided with cross-shaped slots, and the cross-shaped retaining blocks 42 are respectively inserted into the cross-shaped slots).

The connector 2 is inserted into the interior of the outer shell 1, with the upper end of the base plate 41 inserted into the slot 6, thus fixing the entire assembly of the base plate 41 and cross-shaped retainer 42 and preventing rotation of the threaded terminal 8. The rear side of the upper surface of the connector 2 contacts the lower surface of the top plate 16. The top plate 3... The lower end of the pressure plate 14 is pressed down to position the connector 2. The connector 2 and the outer shell 1 are then inserted into the solenoid valve's energizing position. The solenoid valve's energizing plates contact the vertically adjacent contact plates 7 to conduct electrical signals. The internal hex bolt 17 is inserted and tightened, and the positioning seat 51 and the hexagonal post 52 are inserted into the whole. The spring plates 54 are respectively engaged in the interior of the adjacent limiting grooves 55 to limit the internal hex bolt 17. When vibration or impact occurs, the spring plates 54 slightly shake inside the corresponding limiting grooves 55 to prevent the positioning seat 51 from falling off. When the positioning seat 51 needs to be removed, a screwdriver is inserted into the handle 56 to pull up the positioning seat 51. The spring plates 54 have a certain elasticity and automatically retract into the groove 53 when pulled up, making it easy to pull out. When energized, the two contact plates 7, the indicator light 12, and the resistor 11 are connected in series to form a circuit. When the connector is operating normally, the indicator light 12 lights up, and the resistor 11 divides the voltage to prevent excessive current.
