Detailed Implementation
[0027] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0028] This utility model relates to an electrical connection structure for a lamp, including a housing 100 and a connector 300.
[0029] like Figure 1 , Figure 2 and Figure 6As shown, the housing 100 can be configured in a strip-shaped structure. A circuit board 200, which is an aluminum substrate, is installed inside the housing 100. The circuit board 200 has electrical contacts 210, the number of which depends on the application; in this embodiment, two electrical contacts 210 are provided at one end of the circuit board 200. One or two connectors 300 can be provided. The connectors 300 can be installed on the end of the housing 100 to seal the end. Conductive terminals 400 and conductive sheets 500 are installed on the connectors 300. At least two conductive terminals 400 are provided, one for connecting to the positive terminal and one for connecting to the negative terminal. Each conductive terminal 400 is connected to a corresponding conductive sheet 500. The conductive sheet 500 is made of a conductive metal material, such as copper. The conductive sheet 500 is paired with each electrical contact 210. This connection can be achieved through direct contact or by soldering to further fix the conductive sheet 500 to the electrical contact 210. The circuit board 200 is electrically connected to the conductive plate 500 and conductive terminal 400 via electrical contacts 210, conductive sheet 500, and conductive terminal 400. In use, the circuit board 200 is powered by an external power supply component, such as an electrical rail, via the conductive terminal 400. The circuit board 200 then controls the operation of the light-emitting component inside the housing 100. After the connector 300 and the circuit board 200 are assembled, electrical conduction between the electrical contacts 210, conductive sheet 500, and conductive terminal 400 is achieved without the need for wires. The conductive sheet 500 has a fixed shape and position, eliminating the need for wiring or securing wires, and preventing displacement due to shaking or other factors that could obstruct the light-emitting component, thus effectively improving assembly efficiency.
[0030] In one embodiment, such as Figure 6 As shown, the conductive terminal 400 is cylindrical and can be a spring-loaded structure. A conductive sheet 500 is sleeved on the conductive terminal 400. The conductive terminal 400 passes through the connector 300. One end of the conductive terminal 400 extends out of the connector 300 and is exposed outside the housing 100. After installation, the conductive sheet 500 can adhere to the surface of the circuit board 200 without obstructing the light-emitting components or creating dark areas.
[0031] Specifically, such as Figure 5 and Figure 6As shown, the connector 300 has through holes 310. The number of through holes 310 depends on the number of conductive terminals 400. In this embodiment, one connector 300 has two through holes 310, and each through hole 310 corresponds to the installation of one conductive terminal 400. In the illustrated orientation, the circuit board 200 is placed horizontally, and the thickness direction of the circuit board 200 is vertical. The axial direction of the through hole 310 is vertical, and the through hole 310 passes through the connector 300. The through hole 310 includes a first hole portion 311 and a second hole portion 312 coaxially arranged. The diameter of the first hole portion 311 is larger than the diameter of the second hole portion 312. The first hole portion 311 can be configured as a hollow cylinder. The second hole portion 312 can be configured as a hollow cylinder, or it can be configured as a funnel shape, etc. The conductive terminal 400 includes a first post segment 410, a second post segment 420, and a spring pin segment 430 arranged coaxially in sequence. The outer diameters of the first post segment 410, the second post segment 420, and the spring pin segment 430 decrease progressively, i.e., the outer diameter of the first post segment 410 is larger than that of the second post segment 420, and the outer diameter of the second post segment 420 is larger than that of the spring pin segment 430. The spring pin segment 430 can elastically expand and contract relative to the second post segment 420. The second post segment 420 passes through the conductive sheet 500. During installation, the second post segment 420 and the spring pin segment 430 are passed through the through hole 310. The second post segment 420 is fitted into the first hole 311, and the second post segment 420 and the first hole 311 can be an interference fit to fix the conductive terminal 400 in the through hole 310. Alternatively, the second post segment 420 and the first hole 311 can be fixed by applying adhesive. The spring pin segment 430 passes through the second hole 312 out of the through hole 310 and is located outside the housing 100. The outer diameter of the first column segment 410 is larger than the diameter of the first hole 311. The conductive sheet 500 is clamped between the ends of the first column segment 410 and the first hole 311, thereby fixing the conductive sheet 500 to the connector 300 and making the conductive sheet 500 contact the conductive terminal 400 to achieve electrical conduction. Before the conductive sheet 500 is clamped, the conductive sheet 500 can be rotated relative to the conductive terminal 400 to adjust the relative position of the conductive sheet 500 and the electrical contact 210, ensuring that the conductive sheet 500 and the electrical contact 210 can make full contact.
[0032] In some specific embodiments of this utility model, such as Figure 3 , Figure 4 and Figure 5As shown, the connector 300 includes an extension 320. The extension 320 extends from the connector 300 toward the interior of the housing 100. The extension 320 has a first slot 321, and the circuit board 200 has a plug-in portion 220. The shape of the plug-in portion 220 matches the shape of the first slot 321. In this embodiment, the first slot 321 may be U-shaped and recessed in the vertical direction. The plug-in portion 220 is U-shaped and protrudes from one end of the circuit board 200. The plug-in portion 220 is inserted into the first slot 321 in a first direction perpendicular to the thickness direction of the circuit board 200. In the figure, the thickness direction of the circuit board 200 is the vertical direction, and the first direction is the horizontal direction. During installation, the plug-in portion 220 of the circuit board 200 is first inserted into the first slot 321, and the circuit board 200 and connector 300 are positioned and installed through the first slot 321. Then, the circuit board 200 and connector 300 are pushed into the interior of the housing 100 for installation.
[0033] Based on the above embodiment, the inner walls of the front and rear sides of the housing 100 are provided with second slots 110 extending left and right along the first direction. The front and rear sides of the circuit board 200 are respectively inserted into the second slots 110 on both sides. The extension portion 320 is provided with extension edges 322 on both sides, and the extension edges 322 on both sides are respectively inserted into the second slots 110 on both sides, thereby quickly positioning and installing the circuit board 200 and the connector 300 onto the housing 100. The second slots 110 are used to position the circuit board 200 and the connector 300 relative to the housing 100 in the vertical and horizontal directions and the front and rear directions.
[0034] Among them, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, the end of the housing 100 has a notch 120. The shape of the notch 120 is adapted to the shape of the extension 320. The extension 320 is inserted into the notch 120 along a first direction. A mounting cavity 323 is formed inside the first slot 321. The mounting cavity 323 extends vertically through the insertion portion 220 along the thickness direction of the circuit board 200. A magnetic member 600 is installed in the mounting cavity 323. The magnetic member 600 can be a magnet or a metal component that can be attracted by a magnet. The insertion portion 220 covers the side of the mounting cavity 323 facing the inside of the housing 100, while the other opposite side of the mounting cavity 323 is located outside the housing 100, that is, one side of the magnetic member 600 is exposed outside the housing 100. The magnetic member 600 is fixed in the mounting cavity 323 by the circuit board 200. In use, the magnetic member 600 is magnetically attracted and fixed to the magnet or magnetically attracted metal component on the external power supply component.
[0035] Furthermore, such as Figure 2 and Figure 5As shown, the connector 300 has two protrusions 330 on its surface facing the interior of the housing 100, and the protrusions 330 are distributed front to back on the connector 300. When the connector 300 is inserted into the housing 100, the protrusions 330 on the front and back sides respectively abut against the inner walls of the front and back sides of the housing 100. The protrusions 330 on both sides are clamped inward by the inner walls of the front and back sides of the housing 100, thereby fixing the connector 300 to the end of the housing 100.
[0036] In one embodiment, such as Figure 2 , Figure 4 and Figure 6 As shown, a number of LED beads 230 are integrated on the circuit board 200. The housing 100 is provided with a lampshade. The LED beads 230 face the lampshade to illuminate. The LED beads 230 are integrated on the circuit board 200. After the conductive sheet 500 is connected to the electrical contact 210, it can effectively avoid the LED beads 230 and will not cause problems such as blocking the LED beads 230.
