Description

Technical Field

[0001] This utility model relates to the field of dimming power supply technology, and in particular to a press-type dimming power supply. Background Technology

[0002] Press-type dimming power supplies can achieve precise dimming. While adjusting the output voltage or current, the dimming power supply can also adjust the brightness of the light source, thereby achieving precise adjustment of the lighting effect.

[0003] The push-button dimming power supply has several connection terminals at both ends for connecting to the cable. The current connection method is to use bolts to tighten the cable. When subjected to accidental impact or dragging, the cable is very easy to separate from the dimming power supply, causing the dimming power supply to malfunction. This requires frequent maintenance of the dimming power supply, increasing the difficulty of using it. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a push-to-dimmer power supply that can increase the connection stability between the cable and the connection terminal, has a simple structure, and is easy to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A push-to-dimming power supply includes a power supply body with connection terminals mounted on both symmetrical sides. Each connection terminal includes a terminal holder, and a conductive spring is disposed within the terminal holder. The two ends of the conductive spring are fixedly connected to the terminal holder, and the middle of the conductive spring is raised upward. The conductive spring is connected to a circuit board located inside the power supply body via a wire. A conductive spring clamping structure is installed within the terminal holder. A cable opening is provided at the outer end of the terminal holder, and the end of the cable passes through the cable opening and is inserted between the conductive spring and the terminal holder. A cable stabilizing structure is fixedly installed within the terminal holder.

[0007] In this way, when connecting the cable to the terminal, the cable end is inserted between the conductive spring and the terminal block after passing around the cable stabilizing structure. The conductive spring pressing structure lifts the middle of the conductive spring upward, so that the cable end and the conductive spring are pressed tightly on the terminal block, thus completing the installation.

[0008] The conductive spring clipping structure is provided in two spaced intervals.

[0009] The conductive spring pressing structure includes a button, with two sliders fixedly installed at the lower end of the button. The terminal block has a groove that slides with the sliders. The lower ends of the two sliders are located inside the terminal block and are fixedly connected by a support plate. The support plate is located below the middle of the conductive spring. Two compression springs are fixedly installed inside the terminal block, and the upper ends of the compression springs are fixedly connected to the support plate.

[0010] The cable stabilizing structure includes two uprights fixedly installed inside the terminal block, with the two uprights spaced apart, and rubber sleeves fixed to the outside of the uprights.

[0011] A support plate is fixedly installed inside the terminal block. The support plate is located between the column and the conductive spring. The support plate and the terminal block are respectively provided with cable support openings.

[0012] The terminal block is provided with a protective cover facing the cable opening. The protective cover has a bayonet at both ends. The terminal block has protruding ribs on both sides that can engage with the bayonet.

[0013] The lower ends of both sides of the terminal block bend outwards.

[0014] In summary, this push-button dimming power supply has the advantages of increasing the connection stability between the cable and the connection terminal, having a simple structure, and being easy to use. Attached Figure Description

In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0020] like Figure 1-4 As shown, a push-to-dimming power supply includes a power supply body 1. Connecting terminals are installed on both symmetrical sides of the power supply body. Each connecting terminal includes a terminal block 2. A conductive spring 3 is disposed within the terminal block. Both ends of the conductive spring 3 are fixedly connected to the terminal block, and the middle of the conductive spring 3 is raised upwards. The conductive spring 3 is connected to a circuit board located within the power supply body via a wire. A conductive spring clamping structure is installed within the terminal block. A cable opening is provided at the outer end of the terminal block. The end of the cable passes through the cable opening and is inserted between the conductive spring 3 and the terminal block. A cable stabilizing structure is fixedly installed within the terminal block.

[0021] In this way, when connecting the cable to the terminal, the cable end is inserted between the conductive spring and the terminal block after passing around the cable stabilizing structure. The conductive spring pressing structure lifts the middle of the conductive spring upward, so that the cable end and the conductive spring are pressed tightly on the terminal block, thus completing the installation.

[0022] In practice, the conductive spring clip clamping structure is arranged in two intervals. This improves the clamping effect and better prevents the cable end from detaching.

[0023] In implementation, the conductive spring pressing structure includes a button 4, with two sliders 5 fixedly installed at the lower end of the button. The terminal block has a groove that slides with the sliders. The lower ends of the two sliders are located inside the terminal block and are fixedly connected by a support plate 6. The support plate is located below the middle of the conductive spring. Two compression springs 7 are fixedly installed inside the terminal block, with the upper ends of the compression springs fixedly connected to the support plate.

[0024] Thus, when the cable end is inserted between the conductive spring and the terminal block, pressing down the button moves the support plate downwards, compressing the spring and releasing the support for the conductive spring. The conductive spring is generally a copper sheet. The cable end is inserted between the conductive copper sheet and the terminal block. Then, releasing the button resets the spring, causing the support plate to move. The support plate pushes the conductive spring to move, pressing the conductive spring and the cable end firmly onto the terminal block, thus completing the connection between the cable end and the conductive spring.

[0025] The two ends of the conductive spring are fixed on the terminal block. This is an existing structure that can be plugged in or glued.

[0026] In implementation, the cable stabilizing structure includes two uprights 8 fixedly installed inside the terminal block, spaced apart, with rubber sleeves fixed to the outer side of each upright. The cable wraps around the two uprights in an S-shape, and the high friction between the cable sheath and the rubber sleeves makes the cable more stable and facilitates better connection with the conductive spring.

[0027] In practice, a support plate 9 is fixedly installed inside the terminal block. The support plate is located between the column and the conductive spring, and a cable support opening is provided directly opposite the support plate and the terminal block. This supports the cable, allowing it to be better positioned between the conductive spring and the terminal block, thus improving stability.

[0028] In practice, a protective cover 10 is provided on the terminal block facing the cable opening. The protective cover has latches at both ends, and protruding ribs on both sides of the terminal block can engage with the latches. The protective cover protects the cable end and also prevents dust from entering the terminal block.

[0029] During implementation, the lower ends of both sides of the terminal block bend outwards to facilitate the installation and removal of the protective cover.

[0030] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
