A kind of circuit board that the LED lamp is housed
Technical field
The utility model relates to a kind of circuit board of the LED of being equipped with lamp, belongs to the improvement technology of circuit board.
Background technology
The existing circuit board that the LED lamp is housed as shown in Figure 1, 2, LED lamp 2 is inserted on the circuit board 1 set jack by two pins 21, pin 21 is connected on the circuit board 1 by the wave-soldering soldering.There is following problem in the circuit board of above-mentioned existing structure: during by the wave soldering pin, when gases are heated, they expand in the enclosure space that forms between LED lamp and the circuit board, heated gas discharges and form bubble in crest scolding tin from LED lamp pin jack, cause LED lamp pin rosin joint, make the LED lamp fixing not firm, also LED lamp jack-up from the circuit board can have been influenced the quality of circuit board greatly when serious.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of to make the fixed circuit board of LED lamp.
The technical solution of the utility model is: a kind of circuit board that the LED lamp is housed, comprise circuit board and LED lamp, and wherein LED lamp plug-in mounting is welded on the circuit board, it is characterized in that the position of corresponding LED lamp on the described circuit board offers one with upper vent hole.
Described LED lamp is inserted on the jack set on the circuit board by two pins.
Described two pins bending is " eight " font.
Described two pins straight cutting is on the set jack of circuit board.
The two pins of described LED lamp is weldingly fixed on the circuit board.
The diameter of described air vent hole is 0.3~1.0mm.
The utility model is because employing position of corresponding LED lamp on circuit board offers the structure of air vent hole, during the welding of LED lamp pin, heated gas in the enclosure space that forms between LED lamp and the circuit board is discharged from air vent hole, can in crest scolding tin, not form bubble, avoid LED lamp pin rosin joint, therefore, the utility model makes the LED lamp fixed, has improved the quality of circuit board greatly.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1:
Shown in Fig. 4,5, the utility model circuit board comprises circuit board 1 and LED lamp 2, and wherein LED lamp 2 plug-in mountings are welded on the circuit board 1, and the position of corresponding LED lamp 2 offers 2 air vent holes 3 on the described circuit board 1.
In the present embodiment, described LED lamp 2 is welded on the jack set on the circuit board 1 11 by two pins 21 plug-in mountings.Described two pins 21 bendings are " eight " font.The diameter of described air vent hole 3 is 0.3~1.0mm.
Embodiment 2:
The present embodiment difference from Example 1 is: two pins 21 straight cuttings of described LED lamp are on the set jack 11 of circuit board 1.
