Description

Technical Field

[0001] This utility model relates to the field of solenoid valve junction box technology, and in particular to a junction box for solenoid valves. Background Technology

[0002] The solenoid valve junction box is the core component for the electrical connection of the solenoid valve, and is mainly used to simplify the wiring process and improve the reliability and safety of the system.

[0003] Currently, solenoid valves are generally composed of two parts: a coil component and a valve body component. The coil component is usually connected to an external control power supply via a junction box. The existing junction box structure mainly uses terminal blocks to connect to the external control power supply. The connection structure has poor stability and is prone to falling off. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned shortcomings by providing a junction box for solenoid valves, thereby improving the stability of plug-in installation and preventing the connector from falling off.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a junction box for a solenoid valve, comprising: Junction box; The mounting base is housed inside a junction box, which is used to protect the mounting base from dust. Multiple terminal blocks are evenly distributed on the mounting base. Multiple snap-fit ​​connectors are provided and are installed on each terminal block to snap onto the terminal block and prevent the snap-fit ​​connectors from falling off the terminal block; The snap-fit ​​connector includes a snap-fit ​​shell and a support frame symmetrically arranged on the outer wall of the snap-fit ​​shell. A pressure plate is hinged on the support frame, and an arc-shaped positioning rod with the hinge point as the center is fixed at one end of the pressure plate. The terminal block has a socket for mounting a positioning rod.

[0006] Furthermore, the terminal block includes a fixed base and terminal posts disposed on the fixed base; It also includes a first wiring hole located on the same side of the mounting base and the terminal block.

[0007] Furthermore, the snap-fit ​​connector also includes a torsion spring disposed between the pressure plate and the support frame, the torsion spring being used to apply a clamping force to the pressure plate acting on the terminal block; The positioning rod is adapted to the insertion hole.

[0008] Furthermore, the snap-fit ​​connector also includes a plug post disposed within the plug housing and a second wiring hole provided within the plug housing that is compatible with the plug post; It also includes wires that are electrically connected to the plug-in post and the second wiring hole respectively on the plug-in housing, and the ends of the wires are equipped with solenoid valves.

[0009] Furthermore, it also includes wire supports, symmetrically arranged inside the junction box, for supporting the wires and ensuring that the wires are evenly distributed inside the junction box.

[0010] Furthermore, it also includes a rubber sleeve, which is installed on the junction box to seal the connection between the junction box and the wires, preventing dust from entering the junction box.

[0011] The beneficial effects of this utility model are reflected in: This invention involves installing a snap-fit ​​connector onto a terminal block. Pressing the pressure plate on the snap-fit ​​connector causes a torsion spring to rotate on a support frame, which in turn rotates a positioning rod. The connector is then installed on a fixed base via a plug-in housing. A plug-in post on the housing is inserted into the first wiring hole, and simultaneously, another plug-in post is inserted into the second wiring hole. This releases the pressure from the pressure plate, causing the torsion spring to rotate the pressure plate around the support frame. The positioning rod on the pressure plate is installed in the insertion hole, limiting the installation of the fixed base and plug-in housing and preventing detachment. A wire guide is then used to prevent wire tangling, and a rubber sleeve guides the wire out of the junction box and connects it to a control valve. This improves the stability of the plug-in installation and prevents the connector from falling off. Attached Figure Description

The positioning rod 55 is inserted into the socket 44 to lock the connector shell 51 and the terminal block 4 together, preventing the connector shell 51 from falling off and improving the stability of the connection.

[0016] In use, manually press the pressure plate 53 on the support frame 52. The pressure plate 53 causes the torsion spring 54 to deform, and the plug shell 51 on the snap-fit ​​connector 5 is inserted into the fixed seat 41. The plug post 56 on the plug shell 51 is inserted into the first wiring hole 43, and the wiring post 42 on the fixed seat 41 is inserted into the second wiring hole 57. Release the pressure plate 53. Under the action of the torsion spring 54, the pressure plate 53 applies a clamping force to the wiring seat 4. The positioning rod 55 on the pressure plate 53 rotates around the hinge between the pressure plate 53 and the support frame 52. The positioning rod 55 is inserted into the socket 44 in an arc shape. The torsion spring 54 provides the clamping force, and the arc shape of the positioning rod 55 avoids squeezing the rear side of the socket 44 during the insertion process. After the positioning rod 55 is pressed in the socket 44, the end section of the positioning rod 55 fits the socket 44, preventing the plug shell 51 from falling off the fixed seat 41.

[0018] In one embodiment, the snap-fit ​​connector 5 further includes a torsion spring 54 disposed between the pressure plate 53 and the support frame 52. The torque of the torsion spring 54 is used to rotate the pressure plate 53 on the support frame 52. The torsion spring 54 is used to apply a clamping force to the pressure plate 53 acting on the terminal block 4. The torque is used to press the positioning rod 55 on the pressure plate 53 into the socket 44 for installation. The positioning rod 55 is adapted to the socket 44, and the number of positioning rods 55 is the same as the number of sockets 44.

[0019] In a specific embodiment, the snap-fit ​​connector 5 further includes a plug post 56 disposed in the plug housing 51 and a second wiring hole 57 opened in the plug housing 51 and adapted to the wiring post 42.
