Description

Technical Field

[0001] This utility model relates to the field of track lighting technology, and in particular to a high-voltage switch for track power supply and a track-type power supply box. Background Technology

[0002] In the modern lighting field, track lights are widely used in commercial spaces, exhibition halls, and other venues due to their convenient installation and flexible positioning. Track lights typically consist of a driver power supply box, a power converter, and a light body connected to the bottom of the driver power supply box. Their power supply relies on conductive metal strips on both sides of the track. One part of these strips supplies high-voltage power, while the other provides low-voltage power. The driver power supply box is equipped with corresponding high-voltage and low-voltage switches. However, due to differences in manufacturers and manufacturing processes, the size or position of the track's grooves can vary. When the high-voltage or low-voltage switch moves the conductive strips into the grooves, the strips may not always be perfectly aligned, potentially resulting in height discrepancies and poor contact between the conductive strips and the conductive metal strips.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0017] This utility model discloses a high-voltage switch for a track power supply, comprising a movable base, a neutral wire take-off component, multiple live wire take-off components, multiple first pushing devices, and multiple second pushing devices.

The neutral wire power take-off component and the multiple live wire power take-off components may come into contact with the upper or lower end face of the strip groove, causing jamming. When the power take-off component is located slightly above the middle of the strip groove, the first pushing device contacts the upper end face of the strip groove and converts the lateral force into a downward thrust, pushing the power take-off component downward toward the middle of the strip groove. When the power take-off component is located slightly below the middle of the strip groove, the second pushing device contacts the lower end face of the strip groove and converts the lateral force into a downward thrust. The upward thrust pushes the power-taking components upwards toward the center of the strip groove, assisting in guiding the neutral wire power-taking components and multiple live wire power-taking components to embed into the strip groove and connect electrically with the conductive metal strip. Simultaneously, as the power-taking components are inserted into the strip groove, the first pushing device presses against the upper end face of the strip groove, and the second pushing device presses against the lower end face of the strip groove. This maintains the power-taking components in the center of the strip groove, in contact with the conductive metal strip, and reduces the swaying amplitude of each power-taking component within the strip groove, improving the connection between the high-voltage switch and the rail. The stability of the connection between tracks; the high-voltage switch of the track power supply disclosed in this application is provided with a first pushing device and a second pushing device to avoid jamming between each power taking part and the strip groove, to assist each power taking part in inserting into the strip groove, to ensure the smoothness of the installation process, and at the same time, to maintain the centering and contact of each power taking part with the metal conductive strip, to make up for the gap between the upper and lower sides of each power taking part and the strip groove, to ensure the stability of the electrical connection between each power taking part and the metal conductive strip, and the stability of the connection between the high-voltage switch and the track.

[0023] This utility model provides a high-voltage switch for a track power supply and a track-type power supply box. To make the purpose, technical solution and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be understood that the terms "top" and other terms indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and should not be construed as limiting this utility model; in addition, the terms "installation" and "connection" should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] like Figure 1-4 As shown in the figure, this application proposes a high-voltage switch for a track power supply, including a movable base 1, a neutral wire power take-off component 2, multiple live wire power take-off components 3, multiple first pushing devices 4, and multiple second pushing devices 5. The neutral wire power take-off component 2 and the multiple live wire power take-off components 3 are respectively disposed on the movable base 1. One end of the neutral wire power take-off component 2 extends outward toward the movable base 1 to form a neutral wire power take-off terminal. One end of each live wire power take-off component 3 extends outward toward the movable base 1 to form a live wire power take-off terminal. The multiple first pushing devices 4 are respectively disposed one-to-one on the top of the neutral wire power take-off terminal and the multiple live wire power take-off terminals. The multiple second pushing devices 5 are respectively disposed one-to-one on the bottom of the neutral wire power take-off terminal and the multiple live wire power take-off terminals.

[0026] This utility model discloses a high-voltage switch for a track power supply, comprising a movable base 1, a neutral wire power take-off component 2, multiple live wire power take-off components 3, multiple first pushing devices 4, and multiple second pushing devices 5. One end of the neutral wire power take-off component 2 extends outward toward the movable base 1 to form a neutral wire power take-off terminal, and one end of each live wire power take-off component 3 extends outward toward the movable base 1 to form a live wire power take-off terminal. When using this high-voltage switch, the movable base 1 drives the neutral wire power take-off component 2 and the multiple live wire power take-off components 3 to rotate and be inserted into the track. Within the strip-shaped cable groove, the neutral wire power take-off component 2 and the multiple live wire power take-off components 3 may come into contact with the upper or lower end face of the strip-shaped cable groove, causing jamming. When the power take-off component is located slightly above the middle of the strip-shaped cable groove, the first pushing device 4 contacts the upper end face of the strip-shaped cable groove and converts the lateral force into a downward thrust, pushing the power take-off component downward toward the middle of the strip-shaped cable groove. When the power take-off component is located slightly below the middle of the strip-shaped cable groove, the second pushing device 5 contacts the lower end face of the strip-shaped cable groove and converts the lateral force into a downward thrust, pushing the power take-off component downward toward the middle of the strip-shaped cable groove. The force is converted into an upward thrust, pushing the power-taking component upwards towards the center of the strip groove. This assists in guiding the neutral wire power-taking component 2 and multiple live wire power-taking components 3 into the strip groove and making electrical connection with the conductive metal strip. Simultaneously, as the power-taking component is inserted into the strip groove, the first pushing device 4 presses against the upper end face of the strip groove, and the second pushing device 5 presses against the lower end face of the strip groove. This maintains the power-taking component in the center of the strip groove, in contact with the conductive metal strip, and reduces the swaying amplitude of each power-taking component within the strip groove, thereby improving the high-voltage... The stability of the connection between the switch and the track; the high-voltage switch for track power supply disclosed in this application is provided with a first pushing device 4 and a second pushing device 5 to prevent each power taking part from getting stuck in the strip groove, to assist each power taking part in inserting into the strip groove, to ensure the smoothness of the installation process, and at the same time, to maintain the centering and contact of each power taking part with the metal conductive strip, to make up for the gap between the upper and lower sides of each power taking part and the strip groove, to ensure the stability of the electrical connection between each power taking part and the metal conductive strip, and the stability of the connection between the high-voltage switch and the track.

[0027] The first pushing device 4 and the second pushing device 5 on the neutral wire power take-off component 2 are offset along the width direction of the neutral wire power take-off end. Similarly, the first pushing device 4 and the second pushing device 5 on any of the live wire power take-off components 3 are offset along the width direction of the live wire power take-off end. In this application, the movable seat 1 drives the neutral wire power take-off component 2 and multiple live wire power take-off components 3 to rotate into the strip-shaped wire groove. When the width of the strip-shaped wire groove is less than or equal to the height between the opposite sides of the first pushing device 4 and the second pushing device 5, the first pushing device 4 and the second pushing device 5... The pushing device 5 simultaneously contacts the upper and lower end faces of the strip-shaped wire groove, affecting the entry of the neutral wire power take-off component 2 and multiple live wire power take-off components 3 into the strip-shaped wire groove. The first pushing device 4 and the second pushing device 5 are misaligned. When the movable seat 1 drives the neutral wire power take-off component 2 and multiple live wire power take-off components 3 to rotate into the strip-shaped wire groove, the first pushing device 4 and the second pushing device 5 contact the strip-shaped wire groove one after the other. The first pushing device causes the corresponding power take-off component to deform, and the second pushing device hinders the deformation of the power take-off component, ensuring that each power take-off component is smoothly inserted into the strip-shaped wire groove.

[0028] Each of the first pushing devices 4 includes a first protrusion, and each of the second pushing devices 5 includes a second protrusion. The first protrusion and the second protrusion are integrally formed with the neutral wire power take-off device 2 or any of the live wire power take-off devices 3. The structure is simple and the integrally formed structure does not require additional assembly, and the overall strength is higher.

[0029] The first protrusion and the second protrusion have the same structure. The first protrusion is cylindrical in shape and has a rounded corner 41 at its edge. The cylindrical structure has a small contact area with the strip groove, which reduces the friction between the protrusion and the strip groove. The rounded corner 41 also helps guide the first or second protrusion into the strip groove, improving the smoothness of the assembly process.

[0030] In other embodiments, the first protrusion may be in the shape of an elliptical cylinder, a cube, or a protrusion.

[0031] The neutral wire power take-off terminal and the multiple live wire power take-off terminals are all provided with inclined surfaces 42 at the ends away from the movable base 1. The neutral wire power take-off terminal and the multiple live wire power take-off terminals are all provided with notches 43 on one side. When the movable base 1 drives each power take-off component to connect with the metal conductive strip, the inclined surfaces 42 are provided to gradually increase the pressure between each power take-off component and the metal conductive strip, which facilitates the assembly of the high-voltage switch with the track. At the same time, the notches 43 provide a certain deformation space for the ends of each power take-off component, avoiding excessive pressure between each power take-off component and the metal conductive strip, so that the live wire power take-off component 3 and the neutral wire power take-off component 2 are less likely to jam when they come into contact with the metal conductive strip.

[0032] This utility model also provides a track-mounted power supply box, including a housing 6, a power conversion module 7, a low-voltage switch 8, a drive device 9, a shifting device 10, a live wire output component 11, a neutral wire output component 12, a phase power extraction component 13, and a high-voltage switch as described above.

The first pushing device 4 and the second pushing device 5 are respectively disposed on the upper and lower sides of the first low-voltage power take-off end. The first pushing device 4 and the second pushing device 5 are respectively disposed on the upper and lower sides of the second low-voltage power take-off end. By disposing the conductive sheets of the high-voltage switch and the low-voltage switch 8 on the first pushing device 4 and the second pushing device 5 respectively, the stability of the electrical connection between the high-voltage end and the low-voltage end of the track-type power box and the metal conductive strip is ensured, while reducing the shaking between the track-type power box and the track.
