Description

The location structure improvement of light-emittingdiode

Technical field

The utility model relates to the location structure improvement, and aiming to provide one can be positioned light-emittingdiode on the circuit board really, and can not produce the crooked light-emittingdiode location structure in position.

Background technology

When generally the circuit board of tradition use is on the grafting electronic component, all be with light-emittingdiode (Light-Emitting diode; LED) lampshade is directly filled in the hole of predeterminated position; so regular meeting have the lamp socket of light-emittingdiode can't alignment holes in; to retract original position again and again; and the situation that regular like this displacement easily causes each pin of light-emittingdiode to fracture; or each pin distortion abuts against together; and the situation that is short-circuited is very undesirable in the use.

So also occur a kind of stacker structure of protecting light-emittingdiode on the market; as shown in Figures 1 and 2; it is the stacker of forming for a cuboid 1; be provided with a recess 11 that holds light-emittingdiode lampshade 21 in cuboid 1 one side; recess 11 bottoms are provided with a plurality of horizontal seats hole 12; and having a plurality of pin grooves 13 in the rear side of this cuboid 1, this pin groove 13 also communicates with seat hole 12, and cuboid 1 is provided with two cylinders 14 that protrude in the bottom.

During overall package, the lampshade 21 of light-emittingdiode 2 is placed in the recess 11, make the pin 22 of light-emittingdiode pass in the hole 12 simultaneously and then bending is covered in the pin groove 13, with protection light-emittingdiode each pin 22 and unlikely being collided in lampshade 21 joints; Yet, when the cylinder 14 of stacker bottom is plugged on the circuit board 3, and the lampshade misalignment of light-emittingdiode is when presetting out in the hole of optical position, because of stacker is the moulding of cuboid, therefore be subject to the situation that external force causes an end to tilt, and then lampshade more departed from preset out optical position, and must assemble once more, not only waste man-hour, and be easy to generate the situation of pin distortion.

The utility model content

In view of this, main purpose of the present utility model is that light-emittingdiode is positioned on the circuit board really, and can not produce the crooked light-emittingdiode location structure in position.

For achieving the above object, location structure of the present utility model consists predominantly of: holder and lid, this holder one side is provided with a fluting to be recessed on, each is slotted down and shape is the support portion that stretches out gradually and take the form of inclined plane, this bottom, support portion also forms the perforation that communicates with each fluting, and the holder bottom also is provided with more than one keeper, its holder top is formed with a locating slot, the pin of light-emittingdiode is stretched into each perforation respectively, and each pin is inserted in each fluting, form lateral bending portion in each pin of fluting and locating slot joint lateral bending, the lampshade of light-emittingdiode is positioned in the locating slot, at last lid is positioned the locating slot top, and light-emittingdiode is located really, and this light-emittingdiode can utilize the keeper of holder bottom side, is arranged in the predefined position of circuit board.

The beneficial effects of the utility model are: can obtain one can be positioned light-emittingdiode on the circuit board really, and can not produce the crooked light-emittingdiode location structure in position.

The specific embodiment

For the clear structure of the present utility model of your auditor is formed, and the overall operation mode, cooperate graphic being described as follows now:

The location structure improvement of the utility model light-emittingdiode, the structure of its location structure is formed can be as Fig. 3 A, B and shown in Figure 4, consist predominantly of holder 41 and lid 42 in this location structure 4, its holder 41 tops are formed with a locating slot 411, in the locating slot 411 and be provided with washer 412, holder 41 1 sides are provided with a fluting 413 to be recessed on, each is slotted 413 times and shape is the support portion 414 that stretches out gradually and take the form of inclined plane, these 414 bottoms, support portion also form and each fluting 413 perforation that communicate 415, and holder 41 bottoms also are provided with more than one keeper 416, lid 42 then is positioned locating slot 411 tops, in the lid 42 and be provided with washer 421.
