Description

Technical Field

[0001] This utility model belongs to the technical field of electrical appliances, and in particular relates to a driver wiring structure. Background Technology

[0002] To achieve timed on / off switching and brightness adjustment, LED lights typically have a driver installed inside the electrical cavity to control the light source module. The driver connects to external components such as the light source module via wiring. However, different countries have different requirements for the wiring materials used in these connections, and existing wiring, such as the output and input lines of the driver's internal power supply, is fixed on the power board. To meet the different requirements for wiring materials and lengths, there are hundreds of different types of drivers, making inventory and management extremely difficult.

[0003] Furthermore, to achieve a waterproof seal, sealant is usually poured into the driver. However, if terminals are added to the driver's power board to accommodate different cables and allow for cable replacement, the sealant will flow into the terminals. After the internal sealant cures and expands, it will push open the spring clips that hold the cables inside the terminals, causing the spring clips to fail and fail to clamp the cables.

[0025] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a driver wiring structure based on this utility model. The advantages and features of this utility model will become clearer from the following description and claims.

[0026] Please refer to Figure 1 and Figure 2 This embodiment provides a driver wiring structure, including:

[0027] The driver housing 1 has a wiring cavity 2 inside, and a wiring terminal 3 is fixed in the wiring cavity 2. The wiring terminal 3 is covered with a protective sleeve 4 to isolate the first sealant injected into the wiring cavity after wiring is completed. By covering the wiring terminal with a protective sleeve, the first sealant is prevented from flowing into the wiring terminal and causing the spring to fail.

[0028] For details, please refer to Figure 3 The terminal block 3 is provided with a wire insertion hole 31 for inserting or removing wires, and a spring piece for fixing the wire is provided inside the wire insertion hole 31; the wiring cavity 2 is filled with a first sealant, and the terminal block 3 is covered with a protective sleeve 4 to prevent the first sealant from flowing into the inside of the terminal block 3.

[0029] The terminal block 3 allows for the insertion and removal of wires. Users can insert corresponding input and output wires as needed, supporting replacement of any wire length and wires conforming to different national safety standards. After wire insertion, the wiring cavity 2 is sealed with sealant for waterproofing. However, if the sealant flows into the terminal block 3 and solidifies and expands, it will cause the spring clips securing the wire inside the terminal block 3 to open, resulting in spring clip failure and inability to clamp the wire. A protective sleeve 4 is provided over the terminal block 3 to prevent sealant from flowing into the terminal block 3 and causing spring clip failure.

[0030] The protective sleeve 4 is provided with an opening 41 for the wire to pass through. When the protective sleeve 4 is put on the terminal block 3, the opening 41 is aligned with the above-mentioned insertion hole 31. In the wiring state, the opening 41 is in contact with the outer wall of the wire inserted into the insertion hole 31 to prevent the first sealant from flowing into the insertion hole 31.

[0031] Furthermore, a second sealant is applied to the opening 41, and the flowability of the second sealant is lower than that of the first sealant.

[0032] Because the second sealant has low fluidity, it does not flow into the terminal 3. Furthermore, applying the second sealant to the opening 41 prevents the more fluid first sealant from flowing into the terminal 3 when it is subsequently poured into the wiring cavity 2. The reason for not applying the second sealant entirely is that applying the less fluid sealant is very troublesome and inconvenient.

[0033] If time permits, apply the first sealant to the entire area. After the first sealant at the opening 41 has cured, pour the first sealant into the wiring cavity 2.

[0034] To facilitate pressing the terminal block 3 and inserting or removing the wire, the protective sleeve 4 can be an elastic element.

[0035] To make the structure of the terminal block 3 easier to see, the protective sleeve 4 can be transparent.

[0036] In this embodiment, the aforementioned terminal block 3 is mounted on the power board 5, and the bottom end of the protective sleeve 4 is aligned with the surface of the power board 5 to prevent sealant from flowing into the connection between the terminal block 3 and the power board 5.

[0037] In this embodiment, there are multiple terminals 3, which are separated by partitions 6. Each terminal 3 is covered with the aforementioned protective sleeve 4. The partitions 6 prevent electromagnetic compatibility issues. Furthermore, different terminals 3 are compatible with different wire specifications, which can meet the needs of different countries.

[0038] In practical applications, when wiring the driver peripherals, first insert the wire 8 into the insertion hole 31 through the opening 41, then apply the second sealant to the opening 41 to seal the wire 8 with the opening 41; then, cover the cover 7, and the wire 8 extends out through the wire hole 71 on the cover 7; finally, pour the first sealant into the wiring cavity 2 through the through hole 72 at the top of the cover 7 to achieve waterproofing. Please refer to the final configuration. Figure 4 The first and second sealants mentioned above can be silicone sealants; specific models will not be described here.

[0039] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they shall still fall within the protection scope of the present invention.
