Description

Technical Field

[0001] This utility model belongs to the field of LED lighting technology, and specifically relates to a connector for mounting LED aluminum substrates. Background Technology

[0002] An LED light consists of an electroluminescent semiconductor chip, which is cured onto a substrate using silver or white glue. The chip is then connected to the circuit board using silver or gold wires, and the entire circuit is sealed with epoxy resin to protect the internal wiring. Finally, a housing is installed. Aluminum substrates for LEDs are widely used in LED circuit boards due to their high heat dissipation, low thermal resistance, long lifespan, and voltage resistance. During installation, the aluminum substrate needs to be connected to the external circuitry using connectors.

[0003] Existing connectors for mounting aluminum substrates typically involve aligning the connector with the pre-drilled threaded holes on the aluminum substrate and then driving in screws for fixation. This type of connection requires external tools and is inconvenient to operate. Utility Model Content

[0004] The purpose of this utility model is to provide a connector for mounting LED aluminum substrates. It has a simple structure, is easy to clamp and connect the aluminum substrate in the base, is easy to operate, and is not easy to loosen after tightening the rotary knob. It is highly practical and suitable for widespread application.

[0005] This utility model provides the following technical solution: a connector for mounting an LED aluminum substrate, including a base, the bottom of the base being a bottom plate, an elastic pad fixedly provided at the front end of the bottom plate, a clamping plate provided above the bottom plate, the two ends of the clamping plate being slidably connected to the base and the elastic pad respectively through vertical sliding rails, and the two sides of the clamping plate being bent downwards;

[0006] The base is fixedly provided with a threaded hole at its rear end, and a threaded rod is provided through the threaded hole. A rotary knob is fixedly provided on the outside of the base. The clamping plate is provided with an angled groove on one side of the base. The bottom of the angled groove passes through the clamping plate and has an upward inclined surface. A push block is provided at the angled groove. A connecting plate is fixedly provided at the bottom of the push block. The threaded rod passes through the connecting plate and is rotatably connected to it.

[0007] The upper surface of the base plate is covered with a grounding plate, which is connected to the grounding plate circuit on the base. A blocking strip is fixedly provided on the base plate in front of the push block.

[0008] Preferably, the lower surface of the propulsion block is provided with a pushing slope, which is in contact with the upward inclined surface of the angled groove, and the two sides of the propulsion block are slidably connected to the sidewall of the angled groove.

[0009] Preferably, the lower surface of the clamping plate is provided with an array of friction patterns, the width of the clamping plate is matched with the aluminum substrate, and the height of the clamping plate is such that the friction patterns can be tightly connected to the upper surface of the aluminum substrate.

[0010] Preferably, the threaded hole is threadedly connected to the push thread on the threaded rod, and the threaded rod has protruding rings on both sides of the connecting plate.

[0011] The advantages of this utility model are: simple structure, easy clamping and power connection of aluminum substrate in base, convenient operation, and not easy to loosen after tightening the rotary knob, making it highly practical, as detailed below:

[0012] This utility model is equipped with a clamping plate. When the end of the aluminum substrate is inserted into the groove formed by the base plate and the clamping plate, and is blocked by the blocking strip, the contact point of the aluminum substrate end is in contact with the contact piece. At this time, the rotary knob is rotated, and under the twisting of the push thread, the threaded rod moves towards the clamping plate. The push block connected to it moves forward, and the pushing inclined surface squeezes the beveled groove, so that the clamping plate is pressed down and pressed tightly above the end of the aluminum substrate. The friction texture on it grips the end. The smaller the inclination of the pushing inclined surface and the pitch of the push thread, the more rotations the rotary knob needs to make. The connecting seat does not need to use tools when fixing the aluminum substrate, and even if the rotary knob becomes loose, the clamping plate is still in a pressed state.

[0020] The structural features of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] See Figure 1-2A connector for mounting LED aluminum substrates includes a base 1, a bottom plate 2 at the bottom of the base 1, an elastic pad 3 fixedly mounted at the front end of the bottom plate 2, and a clamping plate 4 mounted above the bottom plate 2. The two ends of the clamping plate 4 are slidably connected to the base 1 and the elastic pad 3 via vertical sliding rails, allowing the clamping plate 4 to move up and down between the elastic pad 3 and the base 1. The clamping plate 4 is bent downwards on both sides. A threaded hole 12 is fixedly mounted at the rear end of the base 1, and a threaded rod 9 passes through the threaded hole 12. The threaded hole 12 is threadedly connected to a push thread 11 on the threaded rod 9. When the threaded rod 9 rotates, it moves along the threaded hole 12 under the torsion of the push thread 11. The threaded rod 9 is located outside the base 1. A rotating knob 7 is fixed on the side. A clamping plate 4 is located on one side of the base 1 and has an angled groove 5. The bottom of the angled groove 5 passes through the clamping plate 4 and has an upward inclined surface. A push block 6 is provided at the angled groove 5. A connecting plate 10 is fixed at the bottom of the push block 6. A threaded rod 9 passes through the connecting plate 10 and is rotatably connected to it. The threaded rod 9 has protruding rings on both sides of the connecting plate 10. When the threaded rod 9 moves, it pushes the connecting plate 10 and the push block 6 to move. The lower surface of the push block 6 has a pushing inclined surface 13. The pushing inclined surface 13 fits against the upward inclined surface of the angled groove 5. The two sides of the push block 6 are slidably connected to the side wall of the angled groove 5. The push block 6 squeezes the clamping plate 4 to descend.

[0022] See Figure 1-2 The upper surface of the base plate 2 is covered with a contact plate 15, which is connected to the contact base 8 on the base 1. The port of the aluminum substrate is facing downward and attached to the contact plate 15. The base plate 2 is fixedly provided with a blocking strip 16 in front of the push block 6 so that the aluminum substrate is inserted into the designated position. The lower surface of the clamping plate 4 is provided with an array of friction textures 14. The friction textures 14 are pressed on the aluminum substrate to fix it. The width of the clamping plate 4 matches the aluminum substrate, and the height of the clamping plate 4 is sufficient to ensure that the friction textures 14 are tightly connected to the upper surface of the aluminum substrate.

[0023] The connector for mounting LED aluminum substrates of this utility model has a simple structure, which makes it easy to clamp the aluminum substrate in the base and connect it to electricity. It is easy to operate and is not easy to loosen after tightening the rotary knob. It is highly practical and suitable for promotion.

[0024] For specific usage, please refer to... Figure 1-2 The port of the aluminum substrate is inserted into the groove formed by the base plate 2 and the clamping plate 4. After being blocked by the blocking strip 16, the contact point of the port of the aluminum substrate is in contact with the contact piece 15. At this time, the rotary knob 7 is rotated. Under the twisting of the push thread 11, the threaded rod 9 moves towards the clamping plate 4, and the push block 6 connected to it moves forward. The pushing inclined surface 13 squeezes the angled groove 5, so that the clamping plate 4 is pressed down and pressed tightly above the port of the aluminum substrate. The friction texture 14 on it bites the port. The smaller the inclination of the pushing inclined surface 13 and the pitch of the push thread 11, the more times the rotary knob 7 needs to be rotated, and the better the clamping force.
