Technical Field
[0001] This invention relates to the field of switch control equipment technology, specifically to switch control equipment for distribution boxes. Background Technology
[0002] The word "switch" is defined as turning on and off. It also refers to an electronic component that can open a circuit, interrupt current, or allow current to flow to other circuits. The most common switches are electromechanical devices operated by humans, which have one or more electronic contacts. A "closed" contact means that the electronic contacts are conducting, allowing current to flow; an "open" switch means that the electronic contacts are not conducting, forming an open circuit, and current is not allowed to flow. Switches require assembly during production. To enable remote switch control, some switches are equipped with control devices inside the distribution box. These devices control the closing of the switch via signals. To improve contact surface and installation speed, some control devices use U-shaped copper plates connected by screws. When the control device closes the switch, the internal components of the control device will generate a small amount of vibration. If the distribution box is in a fast-paced environment such as a dance hall, long-term vibration will be transmitted to the U-shaped copper plate, causing the screws at that location to loosen and resulting in poor contact. To address these issues, the following solutions are proposed. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the present invention provides a distribution box switch control device, including a controller, a plurality of terminals fixedly connected to the side wall of the controller, and further comprising: The energizing mechanism is fixedly installed on the inner wall of the terminal block; The pressure applying mechanism is fixedly installed on the inner wall of the energizing mechanism; The positioning mechanism is fixedly installed on the outer wall of the energized mechanism. Before use, the controller needs to be fixed inside the distribution box, and it must be ensured that the external current can be transmitted through the positioning mechanism to the power-on mechanism and from the power-on mechanism to the controller.
[0004] Preferably, the energizing mechanism includes: The fixing component is fixedly installed on the inner wall of the terminal block; A limiting component is located on the outer wall of the fixing component; Before use, the fixing component and the limiting component need to be assembled, and the fixing component is installed on the inner wall of the terminal.
[0005] Preferably, the pressure-applying mechanism includes: Auxiliary components are located on the outer wall of the fixed components. The pressure-bearing component has threads located on the inner wall of the auxiliary component; When the pressure-bearing component rotates, some parts of the pressure-bearing component will enter the confinement component.
[0006] Preferably, the positioning mechanism includes: The snap-fit assembly is slidably disposed on the inner wall of the limiting assembly; The conductive component is fitted and mounted on top of the fixed component; In use, the conductive component needs to be placed on top of the fixed component, and the basic wiring connection is completed by twisting the pressure-bearing component.
[0007] Preferably, the fixing component includes a copper base fixedly connected to the inner wall of the terminal block, a copper core is fitted into the inner wall of the copper base, and a screw is threadedly connected to the side wall of the copper base. The copper base is connected to the copper core as a whole by screw one. During installation, the copper base, copper core and screw one need to be assembled together first, and then the copper base is fixed to the inner wall of the terminal.
[0008] Preferably, the limiting component includes a spring-shaped groove formed on the side wall of the copper core, a through hole 1 formed on the top of the copper core, and a clamping groove formed at the end of the spring-shaped groove away from the through hole 1. During the rotation of the pressure-bearing component, some parts will enter the interior of the spring-shaped groove through the through hole.
[0009] Preferably, the auxiliary components include a threaded hole opened in the inner wall of the central through hole of the copper core, and a second through hole opened in the side wall of the copper base; After screw one fixes the copper base and copper core together, through hole two and clamping groove will be at the same horizontal level.
[0010] Preferably, the pressure-bearing component includes a screw threaded to the inner wall of a threaded hole, a ring rotatably connected to the bottom of the screw nut, a spring plate fixedly connected to the bottom of the ring, and a metal sheet fixedly connected to the end of the spring plate away from the ring. There is some resistance when the ring and screw are connected, and the end of the metal sheet is tilted upwards. The gap of the spring groove is larger than the thread gap of the spring sheet.
[0011] Preferably, the buckle assembly includes a pressing plate slidably connected to the inner wall of the clamping groove, a sliding rod fixedly connected to the outer wall of the pressing plate, and a spring plate fixedly connected to the bottom of the sliding rod; Among them, the end of the second spring plate away from the sliding rod is fixedly connected to the side wall of the copper base. In addition, under normal conditions, the second spring plate will drive the sliding rod to slide upward. When the top of the sliding rod is pressed, the second spring plate will be compressed and deformed.
[0012] Preferably, the conductive component includes a U-shaped copper sheet placed on top of a copper base, with an inclined groove on the side wall of the U-shaped copper sheet, and a transmission line fixedly connected to the side wall of the U-shaped copper sheet; During use, the operator needs to place the U-shaped copper sheet on top of the copper base, and the bottom of the U-shaped copper sheet needs to be in contact with the top of the buckle assembly.
[0013] The present invention has the following beneficial effects: (1) This invention addresses the problem of screw rotation caused by vibration during the operation of the controller. It includes a pressure-applying mechanism and an energizing mechanism inside the device. As the top screw continues to rotate, it will penetrate deeper into the spring groove. During this process, since the thread clearance of the spring groove is greater than the clearance of the spring plate, the spring plate that has entered the spring groove will be stretched and accumulate potential energy. The spring plate in the through hole space is also in a deformed state. The ring applies a downward pressure to the screw. When the screw completes the clamping of the transmission component, the spring plate will be completely inside the spring groove and will continue to generate a contracting pressure. Through the application of the above components, when the screw rotates due to vibration, the spring plate generates a contracting force towards the copper base. When the screw is vibrated, it rotates more towards the copper base, effectively preventing the ring from loosening due to vibration.
[0014] (2) The present invention utilizes the characteristic of the above-mentioned ring driving the spring sheet to move down. A conductive component and a metal sheet are provided inside the device. The metal sheet is in an upward state. During the downward movement of the metal sheet, it may directly contact the outer wall of the inclined groove. As the screw continues to rotate, the metal sheet will rotate in the same direction and move up along the inclined groove to the outer surface of the U-shaped copper sheet. Finally, as the ring continues to rotate, the metal sheet will slide along the outer wall of the U-shaped copper sheet. When it reaches the notch position of the U-shaped copper sheet, the metal sheet will spring down and enter the through hole one. Through the application of the above-mentioned components, the spring sheet one can stably enter the interior of the spring groove in various forms.
[0015] (3) The present invention utilizes the feature of the above-mentioned ring moving towards the copper base and sets up a positioning mechanism inside the equipment. As the spring sheet continues to penetrate into the spring groove, the metal sheet will reach the clamping groove position. As the ring slides down, the ring will form a downward pressure on the top of the U-shaped copper sheet. This pressure will be transmitted to the sliding rod, forcing the U-shaped copper sheet and the fixing component to slide down along the inner wall of the clamping groove, so that the bottom of the clamping groove clamps the metal sheet. Through the application of the above-mentioned components, the end of the spring sheet is effectively restricted, preventing the spring sheet from shrinking inside the spring groove due to the shaking force when the equipment shakes, thus reducing the pulling force of the spring sheet and the screws. (4) The present invention utilizes the above-mentioned metal sheet to enter the clamping groove and bear a pressure from top to bottom. When the metal sheet moves downward under pressure, the top outer wall of the spring sheet will change from being in contact with the top inner wall of the spring groove to being separated. This change allows most of the contraction force generated by the deformation of the spring sheet to be transmitted to the through hole, increasing the pulling force of the spring sheet and the screws. Through the application of the above components, it is prevented that the contact area between the spring sheet and the spring groove is too large, which would cause most of the contraction force generated by the spring sheet to be absorbed by the spring groove, resulting in the pulling force of the spring sheet and the screws being too small.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Example 1, please refer to Figure 1 - Figure 7 This invention relates to a switch control device for a distribution box, including a controller 13, with several terminals 14 fixedly connected to the side wall of the controller 13, and further comprising: Power-on mechanism 1 is fixedly installed on the inner wall of terminal 14; Pressure applying mechanism 2 is fixedly installed on the inner wall of energizing mechanism 1; Positioning mechanism 3 is fixedly installed on the outer wall of the power supply mechanism 1; Before use, the controller 13 needs to be fixed inside the distribution box, and it must be ensured that the external current can be transmitted through the positioning mechanism 3 to the position of the power supply mechanism 1, and then from the power supply mechanism 1 to the controller 13.
[0021] The power supply mechanism 1 includes: Fixing component 11 is fixedly disposed on the inner wall of terminal 14; Restriction component 12 is provided on the outer wall of fixing component 11; Before use, the fixing component 11 and the limiting component 12 need to be assembled, and the fixing component 11 needs to be installed on the inner wall of the terminal 14.
[0022] Pressure application mechanism 2 includes: Auxiliary component 21 is formed on the outer wall of fixed component 11; The pressure-bearing component 22 is threaded onto the inner wall of the auxiliary component 21; When the pressure-bearing component 22 rotates, some parts of the pressure-bearing component 22 will enter the confinement component 12.
[0023] Positioning mechanism 3 includes: The snap-fit assembly 31 is slidably disposed on the inner wall of the limiting assembly 12; Conductive component 32 is attached to the top of fixed component 11; Before use, the equipment is first fixed inside the distribution box. Then, the external wiring needs to be connected to the conductive component 32, and the conductive component 32 is placed in the gap between the pressure-bearing component 22 and the fixed component 11, as shown in the figure. Figure 4 The state.
[0024] Example 2, please refer to Figure 3 - Figure 9 The present invention is a switch control device for a distribution box. Based on Example 1, the fixing component 11 includes a copper base 111 fixedly connected to the inner wall of the terminal 14, a copper core 112 is fitted to the inner wall of the copper base 111, and a screw 113 is threadedly connected to the side wall of the copper base 111. The copper base 111 is connected to the copper core 112 as a whole by screw 113. During installation, the copper base 111, copper core 112 and screw 113 need to be assembled together first, and then the copper base 111 is fixed to the inner wall of the terminal 14.
[0025] The limiting component 12 includes a spring-shaped groove 121 formed on the side wall of the copper core 112, a through hole 122 formed on the top of the copper core 112, and a clamping groove 123 formed at the end of the spring-shaped groove 121 away from the through hole 122. During the rotation of the pressure-bearing component 22, some parts will enter the interior of the spring-type groove 121 through the through hole 122.
[0026] The auxiliary component 21 includes a threaded hole 211 opened in the inner wall of the central through hole of the copper core 112, and a through hole 212 opened in the side wall of the copper base 111. When the aforementioned metal sheet 224 enters the clamping groove 123 and is subjected to a downward pressure, as the metal sheet 224 moves downward under pressure, the top outer wall of the spring sheet 223 will change from being in contact with the top inner wall of the spring groove 121 to being separated. This change allows most of the contraction force generated by the deformation of the spring sheet 223 to be transmitted to the through hole 122, increasing the pulling force of the spring sheet 223 on the screw 221. Through the application of the above components, it is prevented that if the contact area between the spring sheet 223 and the spring groove 121 is too large, most of the contraction force generated by the spring sheet 223 will be absorbed by the spring groove 121, resulting in insufficient pulling force of the spring sheet 223 on the screw 221.
[0027] The pressure-bearing component 22 includes a screw 221 threadedly connected to the inner wall of the threaded hole 211. A ring 222 is rotatably connected to the bottom of the screw 221 nut. A spring plate 223 is fixedly connected to the bottom of the ring 222. A metal sheet 224 is fixedly connected to the end of the spring plate 223 away from the ring 222. When the operator twists screw 221, due to the rotational resistance between ring 222 and screw 221, screw 221 will drive ring 222 and spring plate 223 to rotate in the same direction. During this process, as screw 221 continues to penetrate into threaded hole 211, the outer wall of metal plate 224 will contact the outer wall of conductive component 32 and move downward with the rotation of ring 222. At this time, spring plate 223 will be compressed and undergo slight deformation, accumulating potential energy. When metal plate 224 reaches through hole 122, the deformed spring plate 223 will push metal plate 224 into through hole 122. As top screw 221 continues to rotate, screw 221 will continue to penetrate into spring groove 121. During this process, since the thread clearance of spring groove 121 is greater than the clearance of spring plate 223, spring plate 223 entering spring groove 121 will be elongated and accumulate potential energy.
[0028] The buckle assembly 31 includes a pressing plate 311 that is slidably connected to the inner wall of the clamping groove 123, a sliding rod 312 that is fixedly connected to the outer wall of the pressing plate 311, and a spring sheet 313 that is fixedly connected to the bottom of the sliding rod 312. Taking advantage of the characteristic of the ring 222 moving towards the copper base 111, a positioning mechanism 3 is provided inside the device. As the spring plate 223 continues to penetrate deeper into the spring groove 121, the metal sheet 224 will reach the clamping groove 123. As the ring 222 slides downward, it will exert a downward pressure on the top of the U-shaped copper sheet 321. This pressure will be transmitted to the sliding rod 312, forcing the U-shaped copper sheet 321 and the fixing component 11 to slide downward along the inner wall of the clamping groove 123, so that the bottom of the clamping groove 123 clamps the metal sheet 224. Through the application of the above components, the end of the spring plate 223 is effectively restricted, preventing the spring plate 223 from contracting inside the spring groove 121 due to vibration when the device vibrates, thus reducing the pulling force of the spring plate 223 on the screw 221.
[0029] The conductive assembly 32 includes a U-shaped copper sheet 321 placed on top of the copper base 111. A groove 322 is provided on the side wall of the U-shaped copper sheet 321, and a transmission line 323 is fixedly connected to the side wall of the U-shaped copper sheet 321. Utilizing the characteristic of the ring 222 driving the spring sheet 223 downward, a conductive component 32 and a metal sheet 224 are provided inside the device. The metal sheet 224 is in an upward-curved state. During the downward movement of the metal sheet 224, it may directly contact the outer wall of the inclined groove 322. As the screw 221 continues to rotate, the metal sheet 224 will rotate in the same direction and move upward along the inclined groove 322 to the outer surface of the U-shaped copper sheet 321. Finally, as the ring 222 continues to rotate, the metal sheet 224 will slide along the outer wall of the U-shaped copper sheet 321. When it reaches the notch position of the U-shaped copper sheet 321, the metal sheet 224 will spring down and enter the through hole 122. Through the application of the above components, the spring sheet 223 can stably enter the interior of the spring groove 121 in various forms.
[0030] A specific application of this embodiment is as follows: Before use, the equipment is first fixedly installed inside the distribution box. Then, the external lines need to be connected to the conductive component 32, and the conductive component 32 is placed in the gap between the pressure-bearing component 22 and the fixed component 11, presenting as follows. Figure 4 The state.
[0031] To address the issue of vibrations in the controller 13 causing the screw 221 to rotate, a pressure mechanism 2 and an energizing mechanism 1 are installed inside the device. When the operator twists the screw 221, due to the rotational resistance between the ring 222 and the screw 221, the screw 221 will drive the ring 222 and the spring plate 223 to rotate in the same direction. During this process, as the screw 221 continues to penetrate deeper into the threaded hole 211, the outer wall of the metal sheet 224 will contact the outer wall of the conductive component 32 and move downwards with the rotation of the ring 222. At this time, the spring plate 223 will be compressed, undergoing a slight deformation and accumulating potential energy. When the metal sheet 224 reaches the position of the through hole 122, the deformed spring plate 223 will push the metal sheet 224 into the through hole 122. With the continued rotation of the top screw 221, the screw 221 will continuously... As the screw penetrates deeper into the spring groove 121, the spring plate 223, due to its larger thread clearance than the spring plate 223, will elongate and accumulate potential energy. Meanwhile, the spring plate 223 within the through hole 122 is also in a deformed state, applying downward pressure to the screw 221 through the ring 222. When the screw 221 clamps the conductive component 32, the spring plate 223 will be completely inside the spring groove 121, continuously generating a contracting pressure. Through the application of this component, when the screw 221 rotates due to vibration, the spring plate 223 generates a contracting force towards the copper base 111, causing the screw 221 to rotate more towards the copper base 111 when vibrated, effectively preventing the ring 222 from loosening due to vibration.
[0032] Utilizing the characteristic of the ring 222 driving the spring sheet 223 downward, a conductive component 32 and a metal sheet 224 are provided inside the device. The metal sheet 224 is in an upward-curved state. During the downward movement of the metal sheet 224, it may directly contact the outer wall of the inclined groove 322. As the screw 221 continues to rotate, the metal sheet 224 will rotate in the same direction and move upward along the inclined groove 322 to the outer surface of the U-shaped copper sheet 321. Finally, as the ring 222 continues to rotate, the metal sheet 224 will slide along the outer wall of the U-shaped copper sheet 321. When it reaches the notch position of the U-shaped copper sheet 321, the metal sheet 224 will spring down and enter the through hole 122. Through the application of the above components, the spring sheet 223 can stably enter the interior of the spring groove 121 in various forms.
[0033] Taking advantage of the characteristic of the ring 222 moving towards the copper base 111, a positioning mechanism 3 is provided inside the equipment. As the spring plate 223 continues to penetrate deeper into the spring groove 121, the metal sheet 224 will reach the clamping groove 123. As the ring 222 slides downward, it will exert a downward pressure on the top of the U-shaped copper sheet 321. This pressure will be transmitted to the sliding rod 312, forcing the U-shaped copper sheet 321 and the fixing component 11 to slide downward along the inner wall of the clamping groove 123, so that the bottom of the clamping groove 123 clamps the metal sheet 224. Through the application of the above components, the end of the spring plate 223 is effectively restricted, preventing the spring plate 223 from contracting inside the spring groove 121 due to the vibration force when the equipment vibrates, thus reducing the pulling force of the spring plate 223 on the screw 221. When the aforementioned metal sheet 224 enters the clamping groove 123 and is subjected to a downward pressure, as the metal sheet 224 moves downward under pressure, the top outer wall of the spring sheet 223 will change from being in contact with the top inner wall of the spring groove 121 to being separated. This change allows most of the contraction force generated by the deformation of the spring sheet 223 to be transmitted to the through hole 122, increasing the pulling force of the spring sheet 223 on the screw 221. Through the application of the above components, it is prevented that if the contact area between the spring sheet 223 and the spring groove 121 is too large, most of the contraction force generated by the spring sheet 223 will be absorbed by the spring groove 121, resulting in insufficient pulling force of the spring sheet 223 on the screw 221.
