In the existing LED bulb lamp, the electrical connection between a power panel and a light source panel is mostly realized by welding corresponding electrodes on the two panels by 2 leads; however, the connection method is complex in process and is not suitable for full-automatic assembly by adopting automatic assembly equipment; as shown in fig. 1, in the prior art, in order to improve the working efficiency, two pads are used to replace a wire, and an insertion strip with pads on a power board is inserted into a corresponding slot of a light source board in an insertion manner, so that the power board is connected with corresponding electrodes on the light source board through the pads, however, it is found during production that two pads may be connected together to form tin pile, which may result in the situation that the power board is not inserted into the light source board, and needs to be repaired, and there is a risk that the performance of a product is not estimated due to poor contact caused by uneven pads.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a connection pad between bulb lamp power strip and the light source board to overcome not enough among the prior art.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the application discloses connect pad between bulb lamp power strip and light source board, including power strip, joining region, cutting and pad, the front end of power strip is equipped with the joining region, the joining region is kept away from one of power strip and is served and be equipped with two cutting, every be equipped with a pad on the cutting, be equipped with a plurality of toper leg on the pad.
Preferably, the two cutting strips are respectively positioned at the left edge and the right edge of one end of the connecting area, which is far away from the power supply board.
Preferably, the bonding pad is of a rectangular structure, the number of the conical welding feet is 4, and the 4 conical welding feet are respectively positioned at four corners of the bonding pad;
preferably, the central axis of the tapered leg is 135 degrees from the edge of the pad.
Preferably, a fillet is arranged between the conical welding leg and the welding pad.
Preferably, the outer surface of the connection region is provided with a protective film.
The utility model has the advantages that:
the invention relates to a connecting welding disc between a bulb lamp power panel and a light source panel, which consists of a welding disc, and has the key point that a 135-degree conical welding angle is arranged on the edge of the welding disc 4, after the power panel is connected with the light source panel, the power panel enters a wave crest welder for welding at any angle, and when the power panel flows out, the surplus soldering tin is pulled away without residue due to the design of the conical welding angle; the bonding pad is full, flat, good in consistency and perfectly contacted. Thereby promoting production efficiency, reducing production cost and improving the product reliability.
The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
