Description

Technical Field

[0001] This utility model relates to the field of LED power supply technology, and in particular to an LED power supply connector structure. Background Technology

[0002] An LED power supply is a power converter that transforms the power supply into a specific voltage and current to drive the LED to emit light. Typically, the input of an LED power supply includes high-voltage AC (mains power), low-voltage DC, high-voltage DC, and low-voltage high-frequency AC, such as the output of an electronic transformer. While LEDs are shining brightly, LED power supplies are of paramount importance to the development of the LED industry chain. The lifespan and reliability of LED driver power supplies directly affect the lifespan of LED light sources.

[0003] Currently, LED driver power supplies use the following two connection methods:

[0004] 1. The connector is integrally molded with the cable and LED driver power supply housing. If it is damaged, the entire unit must be replaced, which is costly.

[0005] 2. Rubber plugs are installed at the connection points to seal the cables. However, thermal expansion and contraction can cause the rubber plugs to deform, resulting in poor sealing. If water leakage occurs, it can damage the LED power supply. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide an LED power supply terminal structure that can improve waterproof performance, has a simple and stable structure, and is easy to use.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] An LED power supply connector structure is provided on the end plate of an LED power supply housing. The LED power supply housing has a mounting hole. The connector structure includes a cylinder fixedly installed at the mounting hole position. The cylinder is coaxially arranged with the mounting hole. A limit ring is fixedly installed at the inner end of the cylinder, and an external thread is provided at the outer end of the cylinder.

[0009] The connection structure also includes a wire clamp, which is fixed to the outside of the wire and located inside the cylinder. A cover is threaded to the outside of the cylinder, and a retaining ring for limiting the position of the wire clamp is fixedly installed at the outer end of the cover.

[0010] In this way, during connection, the wire is connected to the circuit board inside the LED power supply housing. A wire clamp is then fixed to the outside of the wire, placed inside the cylinder with one end abutting against the limiting ring. Finally, the cover is installed on the outside of the cylinder to complete the installation. The wire clamp secures the wire, and both ends of the clamp are pressed tightly against the limiting ring and the retaining ring, achieving a seal.

[0011] Direction specification: The side of the circuit board closest to the LED power supply is the inner side, and the side furthest from the circuit board is the outer side.

[0012] The wire clamp includes two opposing semi-circular clamp bodies. The ends of the clamp bodies extend outward to form connecting ends. One clamp body has several plastic buckles fixedly installed at its connecting end, and the other clamp body has a snap hole fixedly installed at its connecting end to engage with the plastic buckles.

[0013] The wire clamp has several positioning pins fixedly installed at its end, and the limiting ring has positioning holes that engage with the positioning pins.

[0014] The hoop has several arc-shaped ribs fixedly installed on its outer side, and the two ends of the arc-shaped ribs are fixedly connected to the connecting ends of the hoop.

[0015] The solid has an inner groove on its inner side, and a sealing ring is fixedly installed in the inner groove.

[0016] The hoop has outer grooves on both sides, and sealing rings are fixedly installed in the outer grooves.

[0017] The end of the cover away from the retaining ring extends outward to form an outer edge, and a sealing gasket is provided between the outer edge and the end cover.

[0018] In summary, this LED power supply connector structure has the advantages of improved waterproofing, simple and stable structure, and ease of use. Attached Figure Description

[0028] like Figure 1-8 As shown, an LED power supply connector structure is provided on the end plate 2 of the LED power supply housing 1. The LED power supply housing has a mounting hole. The connector structure 3 includes a cylinder 4 fixedly installed at the mounting hole position. The cylinder is coaxially arranged with the mounting hole. A limit ring 5 is fixedly installed at the inner end of the cylinder. The outer end of the cylinder is provided with an external thread.

[0029] The connection structure also includes a wire clamp, which is fixed to the outside of the wire and located inside the cylinder. A cover 6 is threadedly connected to the outside of the cylinder, and a retaining ring 7 for limiting the position of the wire clamp is fixedly installed at the outer end of the cover.

[0030] In this way, during connection, the wire is connected to the circuit board inside the LED power supply housing. A wire clamp is then fixed to the outside of the wire, placed inside the cylinder with one end abutting against the limiting ring. Finally, the cover is installed on the outside of the cylinder to complete the installation. The wire clamp secures the wire, and both ends of the clamp are pressed tightly against the limiting ring and the retaining ring, achieving a seal.

[0031] Direction specification: The side of the circuit board closest to the LED power supply is the inner side, and the side furthest from the circuit board is the outer side.

[0032] In implementation, the wire clamp includes two opposing semi-circular clamp bodies 8. The ends of the clamp bodies extend outwards to form connecting ends 9. One clamp body has several plastic clips 10 fixedly installed at its connecting end, while the other clamp body has locking holes 11 fixedly installed at its connecting end to engage with the plastic clips. The two clamp bodies are connected via the plastic clips and locking holes, and fixed to the outside of the wire. The clamp bodies are located inside a cylinder to prevent the wire from sliding relative to the power source, thus improving the sealing effect. The plastic clips are an existing structure, facilitating connection and use.

[0033] During implementation, several positioning pins 12 are fixedly installed at the end of the wire clamp, and the limiting ring has positioning holes 13 that engage with the positioning pins. This positions the wire clamp during installation.

[0034] During implementation, several arc-shaped ribs 14 are fixedly installed on the outer side of the hoop, and the two ends of the arc-shaped ribs are fixedly connected to the connecting ends of the hoop at both ends. This improves the strength of the wire clamp.

[0035] In practice, an inner groove 15 is formed on the inner side of the solid, and a sealing ring is fixedly installed in the inner groove. This improves the sealing effect and prevents water leakage between the wire clamp and the wire.

[0036] In practice, the hoop has outer grooves 16 on both sides, and sealing rings are fixedly installed in the outer grooves. This improves the sealing effect and prevents water leakage between the hoop and the retaining ring and the limiting ring.

[0037] In practice, the end of the cover furthest from the retaining ring extends outward to form an outer edge 17, and a sealing gasket is provided between the outer edge and the end cover. This improves the sealing effect and prevents water leakage between the cover and the end plate.

[0038] The LED power supply includes a cylindrical housing and end plates fixedly mounted at both ends of the housing, with the wiring interface located on the end plates.

[0039] 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.
