The power of the power board is passed from The power wire extending from the LED lamp body is transmitted to the LED in the LED bulb.

The existing LED light bulb power board is basically connected to the power line in the form of a power column. Two power posts are set up on the LED power supply board, and the power posts are respectively electrically connected with the positive pole and the negative pole on the power supply board, and the power cord is wound on the power post or welded on the power post. Because most of the LED power boards are relatively small, the height of the power column is limited and there are electronic devices around it, which makes winding difficult. At the same time, when the low-height power column is winding the power cord, the power cord is prone to loosening and falling off; The electronics surrounding the power pole also make it more difficult to solder the power cord to the power pole. Due to the limitation of the connection mode between the power cord and the power board, it is more difficult to realize automatic winding welding.

Detailed ways

The present invention will be further described below in conjunction with drawings and embodiments.

As shown in Figure 1-2, the LED light bulb power supply board with the power cord clamping type of the present invention includes a power board 1; the power board is provided with a power circuit, welding points for welding electronic components and positioning holes 4, and the positioning holes 4 are used The positioning function between the power board 1 and the bulb shell; the power board 1 is also provided with two conductive clamping components 2; one conductive clamping component 2 is electrically connected to the positive pole of the power supply board 1, and the other conductive clamping component 2 It is electrically connected to the negative pole of the power board 1 ; the power line is electrically connected to the positive pole and the negative pole of the power board 1 through the clamping of the conductive clamping component 2 .

Example 1:

The conductive clamping assembly 2 is composed of a conductive clamp 21 and two conductive support feet 22 extending downward on both sides of the conductive clamp 21; the conductive clamp 21 is composed of two conductive clips 211 and a conductive back plate 212, the conductive clamp The head 21 can be a copper sheet or other conductive metal, and the conductive clip 211 is turned outward at the clamping mouth, so as to facilitate the insertion of the power cord. The two conductive support feet 22 can also be bent from copper sheets or other conductive metals to form a supporting "L" shape; the conductive clamp 21 is erected on the power board 1 through the conductive support feet 22, and the conductive clip The opening of the head points outward to the outside of the power board 1 ; the conductive support feet 22 are electrically connected to the positive or negative pole of the power board 1 ;

The conductive clamping assembly 2 composed of the conductive clamp 21 and two conductive support feet 22 will be located in different positions on the circuit board due to the layout of the circuit board components, so in order to facilitate the insertion of the power cord, the conductive clamp 21 and the horizontal plane The included angle α can be adjusted between 0°-90°, preferably two angles of 0° and 45°.

When the conductive clamping component 2 is arranged on the inner side of the power board, it is difficult to insert the power cord, so a power cord guiding opening 11 can be opened from the edge of the power board 1 to the conductive clamping component 2, and two conductive support feet 22 Set on both sides of the power cord guiding opening 11, the conductive chuck 21 is erected above the power cord guiding opening 11 by two conductive support feet 22, and the gap between the conductive chuck 21 and the midline of the power cord guiding opening 11 are in the same vertical plane. The power cord can first enter the power cord guide opening 11 from the outside of the power board 1 , and then move to the conductive clip 21 for snap-in operation. The ease of operation is improved, the distance between the power cord and the conductive chuck 21 is shortened, and the power cord is prevented from touching other components.

The inner surface of the conductive clamp 21 is provided with transverse corrugations. After the power cord is inserted into the conductive clamp 21, contact points can be increased to form multi-point contact and improve contact reliability. The middle part of the inner side of the conductive chuck 21 can protrude outwards to form an arch. After the power cord is clipped into the conductive chuck 21, it contacts with the highest point of the raised arch to form point contact and improve contact reliability.

Example 2:

The conductive clip assembly 2 is a conductive clip 24 with elastic deformation; one side of the conductive clip 24 is fixedly connected to the power board 1; the conductive clip is attached to the positive or negative pole of the power board; the conductive clip is away from the fixed One side of the edge extends out of the flash in the direction away from the power board; due to the elastic deformation of the conductive clamping elastic piece 24, the conductive clamping elastic piece 24 uses the fixed side as the fulcrum to separate from the positive or negative pole of the power supply board 1 by external force. Recover the bonding with the positive pole or negative pole of the power board 1 through elastic deformation, and other force can be generated when the power cord is inserted. The elastic deformation force presses the power cord and the power board 1 together; the power cord is electrically connected to the positive pole and the negative pole of the power board through the clamping of the conductive clamping shrapnel.

When the conductive clamping elastic piece 24 is arranged at the inner position of the power board, the power cord is difficult to engage in the operation, and a power cord guiding opening 11 can be opened from the edge of the power board 1 to the conductive clamping elastic piece 24 . The power cord can first enter the power cord guide opening 11 from the outside of the power board 1 , and then move to the side of the conductive clamping shrapnel 24 for snap-in operation. The ease of operation is improved, the distance between the power cord and the conductive clamping shrapnel 24 is shortened, and the power cord is prevented from touching other components.

Corrugations are provided on the side of the conductive clamping elastic piece 24 adhering to the positive or negative pole of the power board 1 ; the corrugations are perpendicular to the fixed side of the conductive clamping elastic piece.
