Description

Technical Field

[0001] The utility model relates to the technical field of lighting electrical equipment, in particular to a lamp connecting seat for a junction box and a lamp. Background Art

[0002] Current recessed downlights primarily consist of a panel and a lamp base assembly. The panel features a through-hole corresponding to the lamp base assembly, which is mounted on the through-hole. A heat sink is located on the back of the lamp base assembly. The panel also features elastic clips located around the periphery of the lamp base assembly. Downlights are installed on a ceiling with a sandwich structure. A mounting hole is created in the ceiling, and the upper portion of the downlight is inserted into the hole, where it is secured with elastic clips against the inner wall or upper end of the hole. Therefore, recessed downlights cannot be surface-mounted; if surface-mounting is required, surface-mount downlights are preferred.

[0003] However, some occasions have specific requirements for surface-mounted lines. For example, the location where the wire end is output belongs to the setting of a junction box. In this case, both recessed downlights and surface-mounted downlights are difficult to adapt. Utility Model Content

[0046] Lamp connector and lamp installation method: combined Figure 9As shown, the lamp connector is primarily used in conjunction with a junction box 20. The bottom of the junction box 20 has a wiring cavity, and the side walls of the junction box 20 are equipped with multiple knockout plates corresponding to the cavity. (Depending on the location of the conduit, the corresponding knockout plates are removed to create a hole in the side wall of the junction box 20 for installing the conduit connector 30.) The junction box 20 can be pre-buried in the ceiling or mounted on the ceiling's underside. The inner wall of the junction box 20's wiring cavity is equipped with a connecting ear 201, which is provided with a screw hole. (In this embodiment, the inner wall of the junction box 20 has two connecting ears 201, and the screw holes in these two connecting ears 201 correspond to the first connecting hole 12 of the support frame 1 and the second connecting hole 231 of the decorative cover 2.) When the junction box 20 is pre-buried for installation, bolts are inserted through the first connection holes 12 of the support frame 1 and connected to the connection ears 201 of the junction box 20, securing the support frame 1 to the outside of the bottom of the junction box 20. The fixing base 32 of the downlight body 10 is then aligned with the positioning slots 14 of the support frame 1 and inserted. The V-shaped folded edge 51 at the upper end of the elastic buckle 5 engages the upper end of the buckle edge 13, thus completing the installation of the downlight body 10. If the junction box 20 is exposed, a decorative cover 2 is selected to correspond to the position of the conduit connector 30 of the junction box 20. The cover plate 22 on the side wall of the decorative cover 2 is removed, and the decorative cover 2 can then be placed over the junction box 20 to cover the junction box 20 for a more aesthetically pleasing appearance.

[0047] Use bolts to pass through the first connecting hole 12 of the support frame 1, the second connecting hole 231 of the decorative cover 2, and then connect them to the connecting ear 201 of the junction box 20, so that the support frame 1 and the decorative cover 2 are fixed. Then, align the fixing seat 32 of the downlight body 10 with the positioning groove 14 of the support frame 1 and insert it. The V-shaped folded edge 51 at the upper end of the elastic buckle 5 buckles the upper end of the buckle edge 13, and the installation of the downlight body 10 is completed.

[0048] The bolts can be pre-connected to the junction box 20, or connected to both the decorative cover 2 and the junction box 20 simultaneously. Do not tighten the bolts, leaving a gap between the nut and the bottom of the decorative cover 2 or the bottom of the junction box 20. Align the expanded hole 121 of the support frame 1 with the nut and fit it over the bolt. Rotate the support frame 1 so that the arcuate section of the first connecting hole 12 fits over the bolt and rests on the nut. At this point, rotate the support frame 1 within a certain range to position it in a suitable position for mounting the downlight body 10. Finally, tighten the bolts to secure the support frame 1.
