Abstract
The utility model discloses a connection structure of a light emitting diode and a circuit board. The connection structure comprises the circuit board and the light emitting diode. Vias which are matched with a short pin and a long pin of the light emitting diode are respectively arranged on the circuit board. The light emitting diode is inserted in the vias respectively through the short pin and the long pin. A pillar which is used for fixing the height of the light emitting diode is arranged between the circuit board and the light emitting diode. According to the utility model, the pillar is added between the circuit board and the light emitting diode; in application, a suitable pillar can be selected according to an instrument casing, a switch box and the height of the light emitting diode, so as to realize the unity of the welding height of the light emitting diode; and the connection structure provided by the utility model has the advantages of convenient and rapid operation, time saving, effort saving and good use effect, can greatly improve the efficiency especially in batch products, and can be widely used for the connection of the LED light emitting diode and the circuit board.
Description
Technical field
The utility model belongs to technical field of electronic products, relates to the syndeton of a kind of light-emitting diode and wiring board.
Background technology
As everyone knows, the electronic products such as most of instrument, switch enclosure all need indicator light.Indicator light mostly is to make by welding in the circuit board light-emitting diode at present.As shown in Figure 1, in the via hole 11 that length pin 21 and the long pin 22 of light-emitting diode 2 inserted respectively wiring board 1, and then short pin 21 and the long pin 22 of light-emitting diode 2 be weldingly fixed on the wiring board 1, adopt this welding manner welding operation very inconvenient, the perpendicularity of light-emitting diode pin and wiring board be can not be guaranteed, be difficult to guarantee simultaneously the welding and assembling height of light-emitting diode.Yet the light-emitting diode that common procurement is returned all is the standard specification with level altitude, but in application because the restriction of meter case, switch enclosure shell etc., the welding and assembling height of light-emitting diode is had strict requirement.In order to satisfy the requirement of light-emitting diode height, at present normally two pins of light-emitting diode are put respectively thin plastic pipe (as shown in Figure 2), insulating properties when welding to guarantee to raise adopts the frock mode to reach the unification of LED welding height again.Adopt this mode because pin overlaps respectively thin plastic pipe, and thin plastic pipe is softer, can not guarantee high unity, operation is wasted time and energy, and production efficiency is low, and welding effect is not good.
The utility model content
For addressing the above problem, the utility model provides the syndeton of a kind of light-emitting diode and wiring board.
The utility model is achieved by following technical solution.
The syndeton of a kind of light-emitting diode and wiring board, comprise wiring board and light-emitting diode, be respectively equipped with the via hole that is complementary with the short pin of light-emitting diode and long pin on the described wiring board, light-emitting diode is inserted in the via hole by short pin and long pin respectively, is provided with between wiring board and light-emitting diode for the fixing pillar of light-emitting diode height.
Described pillar is provided with the installing hole for diode installed.
The size of described installing hole is complementary with the short pin of light-emitting diode and the external dimensions of long pin respectively.
The spacing of described installing hole equals the spacing of short pin Yu the long pin of light-emitting diode.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by setting up pillar between wiring board and light-emitting diode, in application, can select suitable pillar according to the height of meter case, switch enclosure and light-emitting diode, to reach the unification to the LED welding height.The utility model is convenient to operation, and is time saving and energy saving, and result of use is good, especially can raise the efficiency greatly in bulk article.Can be widely used in being connected of LED light-emitting diode and wiring board.

Fig. 2 is the syndeton schematic diagram of light-emitting diode and wiring board behind the traditional thin plastic pipe of increase;
Fig. 3 is the utility model structural representation.
Among the figure: 1-wiring board, 2-light-emitting diode, 3-pillar, the thin plastic pipe of 4-, 11-via hole, the short pin of 21-, the long pin of 22-, 31-installing hole.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
As shown in Figure 3, the syndeton of a kind of light-emitting diode described in the utility model and wiring board, comprise wiring board 1 and light-emitting diode 2, be respectively equipped with the via hole 11 that short pin 21 and long pin 22 with light-emitting diode 2 are complementary on the described wiring board 1, light-emitting diode 2 is inserted in the via hole 11 by short pin 21 and long pin 22 respectively, is provided with between wiring board 1 and light-emitting diode 2 for fixing light-emitting diode 2 pillar 3 highly.The technical program is by setting up pillar 3, at installing type, so that the perpendicularity of the short pin 21 of light-emitting diode 2 and long pin 22 and wiring board 1 is better guaranteed, guarantee simultaneously the welding and assembling height of light-emitting diode 2, so that in application process, light-emitting diode is not subjected to the restriction of meter case, switch enclosure shell etc., can select suitable pillar according to the height of meter case, switch enclosure and light-emitting diode, to reach the unification to the LED welding height, in order to satisfy the requirement of light-emitting diode height.
Described pillar 3 is provided with the installing hole 31 for diode installed 2.
The size of described installing hole 31 is complementary with the short pin 21 of light-emitting diode 2 and the external dimensions of long pin 22 respectively.Short pin 21 and long pin 22 can be cooperated with the via hole 11 of wiring board 1 preferably, can reach better welding effect.
The spacing of described installing hole 31 equals the spacing of short pin 21 with the long pin 22 of light-emitting diode 2.Be convenient to like this installation of light-emitting diode 2 with fixing.
