[0002] Electromagnetic switches are widely used across various industries, most commonly in industrial contactors. Industrial equipment is often subject to vibration during operation, and electromagnetic switches require signal cables to be extended and connected to external signal receivers. Therefore, vibrations can create a pulling relationship between the signal cables and the electromagnetic switch itself during operation. Without proper wiring protection, the cables can become worn or break at the connection after extended operation. Utility Model Content

Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0014] like Figure 1-3 The electromagnetic switch with a wiring harness protection function shown in the figure includes a housing 1 and a protection assembly mounted on the housing 1. The protection assembly includes a metal ring 5, a protection block 1 3, and a protection block 2 4. The metal ring 5 is embedded in the outer wall of the housing 1. The protection block 1 3 and the protection block 2 4 can be combined into an annular protection tube and are made of rubber. One end of the annular protection tube is embedded in the metal ring 5. The outer walls of the protection blocks 1 3 and 2 4 that are in contact with the metal ring 5 are both embedded with a magnetic strip 6. The magnetic strip 6 is fixed to the outer wall of the metal ring 5 by adsorption. The outer wall of the metal ring 5 is provided with a hole. An interlocking groove 10 is provided on one side of the outer wall of the protection block 1 3. A matching block 11 is fixedly mounted on one side of the outer wall of the protection block 2 4. The shape of the matching block 11 is adapted to the interlocking groove 10. The annular protection tube formed by the protection blocks 1 3 and 2 4 has an arcuate edge on the tube opening. The two magnetic strips 6 can form a complete circular ring.

[0015] The outer wall of the housing 1 is fitted with a movable plate 2. The outer wall of the housing 1 is provided with a notch, and the inner wall of the notch is provided with a slide groove 7. Sliders 8 are fixedly installed on the sides of the movable plate 2, and the slides 8 are embedded in the slide grooves 7. Fixed plates 9 are fixedly installed at both ends of the top of the movable plate 2, and the fixed plates 9 are fixedly connected to the top outer wall of the housing 1 via bolts. A threaded hole is provided at the connection between the movable plate 2 and the outer wall of the housing 1. Part of the threaded hole is provided on the movable plate 2, and the other part is provided on the outer wall of the housing 1. The outer wall of the edge of the metal ring 5 is provided with an external thread, and the inner wall of the threaded hole is provided with an internal thread. The metal ring 5 is threadedly installed inside the threaded hole.

[0016] Embodiment: The movable plate 2 is inserted and installed from the notch of the shell 1, the slider 8 cooperates with the slide groove 7, the movable plate 2 slides in the slide groove 7 through the slider 8, the fixed plate 9 fits with the top outer wall of the shell 1, and is fixed with bolts. The movable plate 2 and the shell 1 are combined to form a threaded hole, and the metal ring 5 is threaded into the threaded hole. The outer wall of the metal ring 5 is through-opened with a hole, and a tool can be used to pass through the circular hole to help the metal ring 5 to achieve quick disassembly and assembly. The signal line of the solenoid valve can pass through the center hole of the metal ring 5. Then, the protective block 1 3 and the protective block 2 4 are combined to clamp the signal line in the middle. The matching block 11 is inserted into the fitting groove 10, and the protection block 1 3 and the protection block 2 4 are combined. One end of the protection tube is embedded in the interior of the metal ring 5 and covers the signal line inside the metal ring 5. The magnetic strip 6 is adsorbed on the metal ring 5, which can protect the signal line. The edges of the tube mouth of the protection tube are all curved surfaces. The outer skin of the signal line will not be worn or broken due to long-term friction contact with the edge. The rubber protection tube can reduce vibration, so that the connection end of the signal line and the solenoid valve will not be in a state of pulling each other for a long time, thereby increasing the service life of the signal line.

[0017] When the inner core of the solenoid valve needs to be repaired, the signal line will need to be removed together. In order to prevent the outer skin of the signal line from excessively rubbing against the edge of the metal ring 5 when removing it, the metal ring 5 can be removed from the threaded hole. The protective tube and the metal ring 5 are loosened together, but are always sleeved on the outside of the signal line. Remove the bolts that fix the fixed plate 9 to the outer wall of the shell 1, and pull the movable plate 2 out of the shell 1. This will give the operator more space to remove the signal line, or directly remove the movable plate 2 to obtain more control area to repair the solenoid valve. If the signal line needs to be replaced, after the signal line is separated, remove the metal ring 5 and the protective tube from the signal line. If the signal line does not need to be replaced, you can wait until the inner core of the solenoid valve is repaired and reset, and then fit the movable plate 2, metal ring 5 and the protective tube to the shell 1 again.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
