Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical switches, in particular to a balanced electromechanical integrated switch. Background Technique

[0002] A switch is a type of electronic component, and the word "switch" is interpreted as opening and closing. It also refers to an electronic component that can open a circuit, interrupt the current, or cause the current to flow to other circuits. The most common switch is an electromechanical device operated by humans, which has one or several electronic contacts. The "closing" of the contact means that the electronic contact is conducting and allows current to flow through; the "open circuit" of the switch means that the electronic contact is not conducting to form an open circuit and does not allow current to flow through.

[0003] In traditional mechanical equipment, many switches are used, such as start switches, stop switches, and emergency stop buttons. When these switches are arranged, it is easy to press the wrong one in case of emergency, causing unnecessary losses. Moreover, the emergency stop of the switch cannot respond quickly, and a series of operations are required to reset after the emergency stop. Therefore, a balanced electromechanical integrated switch is proposed. Content of the Utility Model

[0026] A docking plate 4 is fixedly connected to the inner side of the ventilation housing 2. The docking plate 4 penetrates the trigger housing 1. A stop disk 5 is rotatably connected to the inner wall of the trigger housing 1. The docking plate 4 is composed of an outer joint 401, a connecting plate 402, and a moving contact 403. The outer joint 401 is in the shape of a square block with wiring holes on its surface. The outer joint 401 penetrates and is fixedly connected to the outer wall of the ventilation housing 2. The outer joint 401 is fixedly connected to the connecting plate 402. The connecting plate 402 penetrates the trigger housing 1. One end of the connecting plate 402 away from the outer joint 401 is in sliding contact with the moving contact 403. The moving contact 403 is fixedly connected to the stop disk 5.

The contact nipples 111 on both sides of the surface of the elastic contact plate 11 are respectively in contact connection with the twist switch 12 and the docking plate 4. The elastic contact plate 11 can bend after being squeezed by using its own elasticity, so that the contact nipple is connected and fitted with the moving contact 403.

[0030] A twist switch 12 is rotatably connected to the surface of the trigger housing 1. The twist switch 12 includes a knob shaft 121, a pushing plate 122, a positioning key 123, a pressing key 124 and a key position spring 125. The knob shaft 121 is in the shape of a round shaft and penetrates through the trigger housing 1, and a knob switch is arranged outside the trigger housing 1.

The twist switch 12 can rotate to control the rotation position and angle of the pushing plate 122. The key position spring 125 at three angles pushes the pressing key 124 to press the triangular column-shaped positioning key 123, so that it can remain stable at the stop and start positions.

[0031] Working principle: When in use, first fix the circuit to be connected on the surface of the outer joint 401. When different circuits need to be connected and started, rotate the knob shaft 121 to make the pushing plate 122 squeeze one side of the elastic contact plate 11, so that the contact nipples 111 of the elastic contact plate 11 are connected and the two moving contacts 403 on one side are connected, realizing the connection of the two docking plates 4 on one side and enabling the circuit to be connected. When an emergency stop is needed, press the emergency stop button 6 to make the frame 602 squeeze the return spring 603, so that the pressing frame 7 descends to press the rack plate 10. The rack plate 10 compresses the compression spring 9 along the guide rod 8. When the rack plate 10 moves, it pushes the straight tooth ring 502 to rotate, so that the disc 501 drives the moving contact 403 to rotate away from the elastic contact plate 11 to realize the quick response of the emergency stop. While the pressing frame 7 descends, the long strip 701 descends to push the twisted pushing plate 122, so that the pushing plate 122 returns to a position away from the elastic contact plate 11. At the same time, the twisted switch 12 after being pressed is clamped and positioned by the pressing key 124 pushed by the key position spring 125 to quickly align and reset for the next start. After the pressing stops, the return spring 603 and the compression spring 9 drive the switch to quickly reset.
