Detailed Implementation

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Reference Figures 1 to 5 As shown, this utility model provides a quick electrical connection structure for a controller. In one embodiment, it includes...

[0036] The base 3 has a connecting cavity 31 at its top that is adapted to the connecting post 11. A second PCB board 32 is also arranged inside the connecting cavity 31, and a number of elastic contact pieces 33 are provided on the second PCB board 32. A number of connecting slots 34 are provided on the circumferential direction of the inner wall of the connecting cavity 31, and a number of connecting blocks 12 adapted to the connecting slots 34 are provided on the outer wall of the connecting post 11. The connecting post 11 is inserted into the connecting cavity 31 and is engaged with the base 3 through the connecting blocks 12 and the connecting slots 34. When the connecting cover 1 is engaged with the base 3 through the connecting post 11, one end of a number of connecting pins 2 protruding from the bottom of the connecting post 11 respectively abuts against an elastic contact piece 33.

[0037] In this embodiment, the connecting cover 1 is installed at the bottom of the controller as the bottom cover of the controller, and the base 3 is installed on the lamp (the second PCB board 32 inside the base 3 is connected to the main control board of the lamp). The connecting cover 1 and the base 3 can be quickly snapped together via the connecting clip 12 and the connecting slot 34, making installation and disassembly convenient. At the same time, after the controller is installed on the base 3 via the connecting cover 1, one end of the connecting pin 2 on the controller can directly abut against the elastic contact piece 33 to achieve electrical connection (that is, the first PCB board inside the controller is electrically connected to the main control board inside the lamp via the connecting pin 2, the elastic contact piece 33, and the second PCB board 32, thereby enabling the lamp to have a sensing function). In this embodiment, there are no restrictions on the type of controller (such as a lighting sensor, a human proximity sensor, etc.) and lamp, which has good versatility and compatibility and can meet the needs of different application scenarios.

[0038] Furthermore, in this embodiment, two opposing positioning blocks are provided within the connecting cavity 31. Positioning notches are provided at the edges of the second PCB board 32 corresponding to the positioning blocks. Through the positioning blocks and positioning notches, the second PCB board 32 can be easily and quickly installed into the connecting cavity 31. Simultaneously, screw holes are provided on the second PCB board 32, and corresponding holes are provided within the connecting cavity 31. After the second PCB board 32 is installed into the connecting cavity 31, screws can be inserted into the screw holes to lock and fix the second PCB board 32. Furthermore, this invention does not limit the number or distribution of the elastic contact pieces 33 and connecting pins 2. In a preferred embodiment, the number of elastic contact pieces 33 and connecting pins 2 is set to... There are five elastic contact pieces, one of which is circular and located in the middle of the top of the second PCB board 32. The other four elastic contact pieces 33 are waist-shaped and arranged around the circular elastic contact piece 33. This shape design increases the area of ​​the elastic contact pieces 33 to facilitate full contact with the connecting pin 2. The elastic contact pieces 33 are made of elastic material. When the connecting pin 2 abuts against the elastic contact piece 33, the elastic contact piece 33 will undergo appropriate elastic deformation, increasing the contact area and contact pressure with the connecting pin 2, which can ensure low resistance and stability of electrical connection. In addition, the surface of the elastic contact piece 33 is plated to further improve conductivity and corrosion resistance.

[0039] In one embodiment, the connecting slot 34 includes a first engaging slot 341 formed vertically on its inner wall and a second engaging slot 342 formed horizontally on its inner wall along the circumference of the inner wall of the connecting cavity 31; the second engaging slot 342 communicates with the first engaging slot 341, and one end of the first engaging slot 341 extends to the top of the connecting cavity 31 to form a first notch 343. When installing the controller, first align the connecting block 12 with the first snap-fit ​​groove 341 of the connecting slot 34. Then, insert the connecting post 11 into the connecting cavity 31. At this time, the connecting block 12 is simultaneously inserted into the first snap-fit ​​groove 341. Then, rotate the controller clockwise, and the connecting block 12 can be inserted into the second snap-fit ​​groove 342, thereby realizing the quick assembly of the two. It is quick and convenient. At the same time, in order to improve the smoothness of the assembly, preferably, the bottom of the first notch 343 is an inclined surface that slopes downward towards the inside of the connecting cavity 31; and one side of the inner wall of the first snap-fit ​​groove 341 is an outwardly convex arc-shaped surface.

[0040] Furthermore, in this embodiment, a snap-fit ​​protrusion 35 extends downward from the top inner wall of the second snap-fit ​​groove 342. The snap-fit ​​protrusion 35 is located in the middle of the top inner wall of the second snap-fit ​​groove 342, forming a limiting cavity with one end of the inner wall of the second snap-fit ​​groove 342. When the controller is rotated clockwise, the connecting block 12 can be snapped into the limiting cavity. The snap-fit ​​protrusion 35 can limit the connecting block 12, prevent loosening, and ensure the stability of the connection between the two.

[0041] Furthermore, in this embodiment, at least two connecting blocks 12 are provided, and the volume of one connecting block 12 is larger than that of the other connecting blocks 12. The top of the base 3 is also provided with a foolproof block 36, and the foolproof block 36 is arranged close to the connecting slot 34 that is adapted to the larger connecting block 12. By setting the foolproof block 36 and setting the size of one of the connecting blocks 12 to be larger, a foolproof function can be achieved, thereby realizing the precise circumferential and axial positioning of the interface and avoiding misalignment. Preferably, there are four sets of connecting blocks 12 and connecting slots 34. The four sets of connecting blocks 12 are evenly distributed on the outer wall of the connecting post 11 along the circumference of the connecting post 11, and the four sets of connecting slots 34 are evenly distributed on the inner wall of the connecting cavity 31 along the circumference of the connecting cavity 31.
