Description

Technical Field

[0001] The utility model relates to the technical field of rolling door machines, in particular to a sealed self-locking lever conductive motor forward and reverse rotation button control switch. Background Art

[0002] The motor control switches of electric rolling door machines in the prior art all use multiple right-angle wiring contact pieces for connection and wiring. For example, the already published Chinese patent announcement number is CN203774131U, and the patent name is a new rolling door machine push button switch. This uses multiple right-angle wiring contact pieces for connection and wiring. Each right-angle wiring contact piece requires at least two or more screws to fix the wires. In addition to adding a lot of screws, it also adds additional processing procedures, which increases the cost of use. Utility Model Content

[0004] The technical solution adopted by the present invention to solve its technical problems is: the enclosed self-locking lever conductive motor forward and reverse button control switch of the present invention includes a switch housing, and four terminals are provided on the switch housing, namely a forward terminal, a reverse terminal, a stop terminal and a common terminal; the stop terminal is matched with a lever copper sheet, and the other end of the lever copper sheet is in contact with the common terminal. A spring is fixed on the upper end surface of the lever copper sheet, and the upper end of the spring is connected to a lever connecting plate, and the two ends of the lever connecting plate are respectively matched with the two terminal pieces of the forward terminal and the reverse terminal; the lower end of the switch housing is matched with a self-locking plate, and the self-locking plate is matched with the four terminals of the switch housing, and two top shafts are provided in the middle of the self-locking plate, and the two top shafts are pressed on the lever connecting plate.

[0005] The switch housing is provided with three top columns, which are forward rotation top column, reverse rotation top column and stop top column respectively. The upper ends of the forward rotation top column, reverse rotation top column and stop top column are respectively connected to the forward rotation button, reverse button and stop button. The lower ends of the forward rotation top column and reverse rotation top column are matched with the lever connecting plate, and the lower end of the stop top column is pressed on the lever copper sheet.

[0006] The switch housing is provided with a slot in the middle, and the lever connecting plate is clamped in the slot.

[0007] The self-clinching plate is buckled on the card slot, and the self-clinching plate just fits tightly with the card slot, and the self-clinching plate is pressed against the lever connecting plate, and the lever connecting plate and the wiring pieces of the forward terminal and the reverse terminal are kept in a normally open state through two top shafts.

[0008] Under the pressure of the spring, the two ends of the lever copper sheet respectively maintain a normally closed state with the wiring pieces of the common terminal and the stop wiring terminal.

[0009] Compared with the existing technology, the sealed self-locking lever conductive motor forward and reverse button control switch of the utility model completely replaces the right-angle wiring contact piece through the lever copper sheet and the lever connecting plate, which not only reduces the use of screws, but also greatly simplifies the production process and reduces production costs. At the same time, the self-locking plate is used to isolate the wiring ends from the outside world, ensuring the safe use of the switch. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] like Figures 1 to 4 As shown, the sealed self-locking lever conductive motor forward and reverse button control switch of the utility model includes a switch housing 0, and the upper end surface of the switch housing 0 is provided with a forward button 1, a reverse button 2 and a stop button 3. The lower ends of the forward button 1, the reverse button 2 and the stop button 3 are respectively connected to the forward top column 4, the reverse top column 5 and the stop top column 6.

[0016] like Figures 1 to 4As shown, there are four terminals in the switch housing, namely the forward terminal 7, the reverse terminal 8, the stop terminal 9 and the common terminal 10. The forward terminal 7, the reverse terminal 8, the stop terminal 9 and the common terminal 10 are all provided with a terminal lug 11, which is used for connection and conduction. The stop terminal 9 and the common terminal 10 are matched with a lever copper plate 12, and the two ends of the lever copper plate 12 are respectively matched with the stop terminal 9 and the common terminal 10, and maintain a normally closed state. A spring 13 is fixed to the upper end surface of the lever copper plate 12, and the upper end of the spring 13 is connected to a lever connecting plate 14. In addition to being used for elastic pressure between the lever copper plate 12 and the lever connecting plate 14, the spring 13 is also a conductor, used for electrical connection between the lever copper plate 12 and the lever connecting plate 14.

[0017] like Figures 1 to 4 As shown, the two ends of the lever connecting plate 14 respectively mate with the two terminal lugs 11 of the forward terminal 7 and the reverse terminal 8. A slot 15 is provided in the center of the switch housing 0, into which the lever connecting plate 14 is retained. A self-locking plate 16 is fitted at the lower end of the switch housing 0, which locks onto the slot 15. The self-locking plate 16 fits snugly with the slot 15 and presses against the lever connecting plate 14. The self-locking plate 16 mates with the four terminal lugs of the switch housing 0. Two top shafts 161 are provided in the center of the self-locking plate 16, which press against the lever connecting plate 14. The two top shafts 161 maintain the lever connecting plate 14 and the terminal lugs 11 of the forward terminal 7 and the reverse terminal 8 in a normally open state.

[0018] like Figures 1 to 4 As shown, the lower ends of the forward and reverse pillars 4 and 5 are engaged with the lever connecting plate 14, and the lower end of the stop pillar 6 is pressed against the lever copper plate 12. Under the pressure of the spring 13, the two ends of the lever copper plate 12 maintain a normally closed state with the common terminal 10 and the terminal 11 of the stop terminal 9, respectively.

[0019] like Figures 1 to 4As shown, when in use, due to the action of the two top shafts 161 of the self-clamping plate 16, the two top shafts 161 press the lever connecting plate 14 upward, so that the two ends of the lever connecting plate 14 leave the wiring piece 11 of the forward terminal 7 and the reverse terminal 8, so that the lever connecting plate 14 and the forward terminal 7 and the reverse terminal 8 maintain a normally open state. At the same time, the lever connecting plate 14 compresses the spring 13 under the pressure of the self-clamping plate 16, so that the lever copper plate 12 at the upper end of the spring 13 is pushed upward, so that the two ends of the lever copper plate 12 are in contact with the wiring piece 11 of the common terminal 10 and the stop terminal 9, so that the two ends of the lever copper plate 12 maintain a normally closed state with the wiring piece 11 of the common terminal 10 and the stop terminal 9 respectively. When the forward button 1 is pressed, the forward top post 4 at the lower end of the forward button 1 presses down on the lever connecting plate 14, pressing one end of the lever connecting plate 14 against the terminal piece 11 of the forward terminal 7, so that the lever connecting plate 14 and the forward terminal 7 achieve point contact, starting the motor forward. Due to the lever action of the lever connecting plate 14, the other end of the lever connecting plate 14 remains in a normally open state with the reverse terminal 8. Similarly, when the reverse button 2 is pressed, the reverse top post 5 at the lower end of the reverse button 2 presses down on the lever connecting plate 14, pressing the other end of the lever connecting plate 14 against the terminal piece 11 of the reverse terminal 8, so that the lever connecting plate 14 and the reverse terminal 8 achieve point contact, starting the motor reverse. Due to the lever action of the lever connecting plate 14, the other end of the lever connecting plate 14 remains in a normally open state with the forward terminal 7. When the stop button 3 is pressed, the stop top post 6 at the lower end of the stop button 3 presses down on the lever copper piece 12, which compresses the spring 13 downward. At the same time, the two ends of the lever copper piece 12 leave the connection pieces 11 of the stop terminal 9 and the common terminal 10 respectively, so that the stop terminal 9 and the common terminal 10 are separated at a point. Thus, the stop function is realized.

[0020] To sum up, compared with the existing technology, the sealed self-locking lever conductive motor forward and reverse button control switch of the utility model completely replaces the right-angle wiring contact piece through the lever copper sheet and the lever connecting plate, which not only reduces the use of screws, but also greatly simplifies the production process and reduces production costs. At the same time, the self-locking plate is used to isolate the wiring ends from the outside world, ensuring the safe use of the switch.

[0021] The present invention has been described in an illustrative rather than restrictive manner based on the embodiments of the present invention. However, it should be understood that those skilled in the art may make changes and / or modifications without departing from the relevant protection scope defined by the claims.
