As shown in fig. 1 and 2, the connection structure includes a cover plate 100, an elastic sheet structure 200, an elastic sheet receiving case 300, and an optoelectronic assembly 400.

It will be appreciated that the electrical appliances referred to in embodiments of the present utility model may include a wide variety of electrical appliances that require connection to an external power cord. The electrical appliance may in particular be a ceiling lamp.

The incoming lines 110 may include a live line incoming line 111, a neutral line incoming line 112, and a ground line incoming line 113. The release ports 120 may include a live wire release port 121, a neutral wire release port 122, and a ground wire release port 123.

Preferably, the cover plate 100 may form the power line through-hole 130 so as to pass through the power line (which may include the live line 710, the neutral line 720, and the ground line 730), i.e., the power line 700 may be connected to the incoming line 110 through the power line through-hole 130. Here, the power line passing port 130 may communicate the front and rear surfaces of the cap plate 100. The cover plate 100 may further form a receiving chamber 140 to receive or partially receive the elastic sheet structure 200 and the elastic sheet receiving case 300. The wire inlet 110 and the release port 120 may be formed on the surface of the receiving chamber 140.

It can be appreciated that when the connection structure provided in the present embodiment is applied to a lamp, the cover plate 100 can be used as a lens structure for enhancing the lighting effect of the lamp, especially an LED (light emitting diode) lamp.

Preferably, the material of the cover plate 100 (lens structure) may be PC (Polycarbonate) plastic, which has good electrical insulation, corrosion resistance, high temperature resistance, high impact strength, and good flame retardance, and is suitable for direct contact with electrical components such as an elastic sheet.

As shown in fig. 2, 3, and 4, the elastic sheet structure 200 and the elastic sheet receiving case 300 may be disposed at a side of the cover plate 100 near the photovoltaic module 400. The elastic sheet structure 200 may be partially or entirely disposed in the elastic sheet receiving case 300. The spring tab structure 200 may include a live spring tab 210, a neutral spring tab 220, and a ground spring tab 230.

The power cord clamping portions 211, 221, 231 may form a certain angle with the power cord connection portions 212, 222, 232, respectively. The power cord pressing portions 211, 221, 231 may be elastically deformed and form corresponding pressing forces when an external force such as pressing is applied. Gaps for accessing the external power supply line 700 (which may include the live wire 710, the neutral wire 720, and the ground wire 730) may be formed between the power supply line pressing parts 211, 221, 231 and the power supply line connection parts 212, 222, 232. It is understood that this gap may or may not be present when the power cord 700 is not inserted. When the power cord 700 enters the above-mentioned gaps of the power cord pressing portions 211, 221, 231 and the power cord connecting portions 212, 222, 232 of the respective elastic sheets, respectively, the power cord pressing portions 211, 221, 231 may be elastically deformed due to the pressing of the power cord 700. Further, a pressing force is generated to press the live wire 710, the neutral wire 720 and the ground wire 730 to the power line connection parts 212, 222 and 232, respectively, so that the live wire 710, the neutral wire 720 and the ground wire 730 are electrically connected with the power line connection parts 212, 222 and 232, respectively.

It is understood that the diameter of the power cord 700 may be greater than the gap between the power cord clamping portions 211, 221, 231 and the power cord connection portions 212, 222, 232. The elastic sheets 210, 220, 230 may also be made of a plurality of interconnected sheet metal structures, respectively.

Preferably, the power line 700 may be a copper wire. The power cord 700 may be a single-wire (single-core cord). The power cord 700 may have a gauge of 1.5 to 2.5 square millimeters.

Further, the power line releasing notches 214, 224, 234 may be formed at the sides of the power line connection portions 212, 222, 232 and disposed opposite to the power line pressing portions 211, 221, 231.

It will be appreciated that the power cord quick connect structure of this embodiment need not be used in the orientation illustrated. For example, the cover plate 100 may be positioned at the lower side of the photovoltaic module 400 when the ceiling lamp is mounted to the ceiling of a room.

The power line release notches 214, 224, 234 may overlap or partially overlap the power line release port 121, the neutral release port 122, and the ground release port 123, respectively, in a direction perpendicular to the power line connection. The power cord pressing parts 211, 221, 231 can be pressed by a tool such as a straight screwdriver through the power cord releasing notches 214, 224, 234 from the releasing opening 120, so that the power cord pressing parts 211, 221, 231 can no longer form pressing force on the power cord 700, and the connection between the elastic sheet structure 200 and the power cord 700 can be rapidly released by pulling the power cord 700.

As shown in fig. 3, the elastic sheet receiving box 300 may be formed with a plurality of elastic sheet stopper portions 310 (two or three may be formed depending on whether or not the ground line is connected). The elastic piece limiting portion 310 may be disposed on a side of the power cord pressing portion 211, 221, 231 away from the power cord 700 (also a side away from the power cord connecting portion 212, 222, 232). The elastic piece limiting portion 310 can limit the deformation degree of the power cord pressing portions 211, 221, 231, and can prevent the bending angle change from exceeding the elastic deformation range.

The optoelectronic package 400 may include a Printed Circuit Board (PCB) 410, and the printed circuit board 410 may include two pads 411 for contacting the spring sheet structure 200. It will be appreciated that the shape of the pads 411 is not limited and that the pads 411 may be sized to provide sufficient contact with the spring sheet structure 200. The circuit board connection portions 213, 223 of the live wire spring piece 210 and the neutral wire spring piece 220 may be connected to one pad 411 of the printed circuit board 410, respectively, to electrically communicate the power wire 700 to the photovoltaic module 400.

Preferably, as shown in fig. 3, 4 and 5, the circuit board connection parts 213 and 223 may be bent parts, and the cover plate 100 may press the circuit board connection parts 213 and 223 to form a reliable electrical connection with the pads 411.

Preferably, as shown in fig. 3, the cover plate 100 may further be formed with a plurality of power line limiting parts 150, and the plurality of power line limiting parts 150 may be formed at one side of the release port 120 near the wire inlet 110, respectively. The power cord stopper 150 may extend from the release port 120 toward the power cord pressing portions 211, 221, 231 (away from the power cord connection portion). The power cord stopper 150 may extend to partially enter the elastic sheet receiving case 300. When the power cord 700 is connected to the elastic sheet structure 200 from the wire inlet 120, the power cord limiting portion 150 can prevent the power cord 700 from extending between the power cord releasing notches 214, 224, 234 and the power cord pressing portions 211, 221, 231 to block the releasing opening 120 and the power cord releasing notches 214, 224, 234. So that the connection of the elastic sheet structure 200 to the power cord 700 is released through the release opening 120.

Preferably, the ground spring tab 230 may be connected to the appliance housing by a ground connection bolt 240. The housing of the ceiling lamp, and in particular the base 500, as mentioned below.

When the power line is released: the power cord pressing portions 211, 221, 231 are pressed by a tool such as a straight screwdriver through the power cord releasing notch from the releasing opening 120, so that the power cord pressing portions 211, 221, 231 no longer form pressing force on the power cord 700, and the connection between the elastic sheet structure 200 and the power cord 700 can be rapidly released by pulling out the power cord 700.
