A kind of welding structure of light emitting diode
Technical field
The utility model is related to a kind of welding structures of light emitting diode.
Background technology
Light emitting diode, it is resistance to it is mild bear the time and be not it is very long, in the welding process it should be noted that the temperature of welding and
Time, temperature is excessively high, and overlong time can all burn out chip.In order to preferably protect light emitting diode, light emitting diode colloid with
PC plate should keep the spacing of 2mm or more, so that welding heat removes in pin.Existing dual platen welds light emitting diode, right
Technology requires relatively high, it is easy to pin be scalded so that light emitting diode does not work.
Utility model content
The purpose of this utility model is to provide a kind of welding structure of light emitting diode.
What the utility model needed to solve is existing dual platen welding light emitting diode, exists and easily pin is scalded, make
Obtain the problem of light emitting diode does not work.
For realization the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of welding structure of light emitting diode, including pcb board, light emitting diode.The pcb board is single sided board, pcb board
It is equipped with joint-cutting, via and pad, the joint-cutting is located at the pad side of light emitting diode.The pin of light emitting diode was inserted into
Hole is simultaneously bent to along pcb board bottom surface at joint-cutting, then is folded over pcb board top surface along joint-cutting, and joint-cutting is exposed in the end of the pin
Top surface is simultaneously fixed with pad solder.
The welded of the utility model has the beneficial effect that:
1, the pcb board employed in the utility model is single sided board, reduces PCB material cost.
2, LED welding method provided by the utility model, bending light emitting diode pin are welded, are increased again
Big pin weld length, can be such that welding heat is removed in pin, pin is avoided to scald, make welding light emitting diode process
It is convenient and safe.
3, LED welding method provided by the utility model, the top surface of pin bending to pcb board are welded, nothing
It need to be welded from the bottom surface of pcb board, more convenient operation.

Specific implementation mode
Referring to Fig. 1, a kind of welding structure of light emitting diode, including light emitting diode 2, pcb board 1.The pcb board 1 is adopted
With single sided board, pcb board 1 is equipped with joint-cutting 2, via 4 and pad 5, and the pad 5 of the light emitting diode 2 can be located at the one of via 4
Two pins 6 of side or both sides, the light emitting diode 2 correspond to two pads 5 respectively, and the joint-cutting 3 is located at light emitting diode 2
Pad 5 at.
Referring to Fig. 2, the pad 5 of the light emitting diode 2 is located at the side of via 4, and two pins 6 of luminous tube 2 are inserted into
Via 4 is simultaneously bent at joint-cutting 3 along 1 bottom surface of pcb board is equidirectional, then is folded over 1 top surface of pcb board along joint-cutting 3, the pin 6
Expose the top surface of joint-cutting 3 respectively and be welded and fixed with pad 5 in end.
Referring to Fig. 3, if the pad 5 of the luminous tube 2 is located at the both sides of via 4, two pins of light emitting diode pipe 2
It is not bent in the same direction at joint-cutting 3 along 1 bottom surface of pcb board after 6 insertion vias 4, remaining welding process is constant.
Welding structure described in the utility model can be widely applied in the welding of light emitting diode, can also be applied to
Other are caused due to sweating heat in the component welding of failure, and the utility model can reduce the cost of pcb board material, can make welding
Process is convenient and safe easy to operate.
