Abstract
The utility model discloses a structure for fixing a component of an LED driver on a circuit board, wherein the component adopts a horizontal mounting structure; a notch is formed on the circuit board, and the component main body is embedded into the notch. By adopting the fixing structure provided by the utility model, the height of the driver is smaller than the sum of the diameter of the component and the thickness of the circuit board, so that the integral height of the driver can be greatly lowered, and the mounting height requirement can be still satisfied after an insulating sleeve is sleeved when the LED driver adopting the fixing structure is assembled into a lighting tube.
Description
Technical field
The utility model relates to led driver, relates in particular to the fixed structure of components and parts on circuit board of led driver.
Background technology
The LED illumination is described as third generation illumination, is in the develop rapidly stage in lighting field.At present; when replacing traditional lighting by the LED illumination; can adopt built-in driver mostly; but, because the space in the LED light fixture is limited, the problem of LED lamp interior appears driver to be installed in through regular meeting; therefore; in order to adapt to small size design, very harsh to the requirement of whole driver size, particularly for the requirement for height of the built-in drive of LED spot.Most of producer is when the built-in drive of LED spot is produced in design, usually have following processing method, on the one hand be that front (A face) with circuit board is the installed surface of plug-in unit components and parts, the back side (B face) is as the lead surface of pin, like this, the height of driver will comprise the pin length at the back side; Be that asthenic components and parts such as electrochemical capacitor (can be the plug-in unit components and parts) are adopted horizontal mounting structure on the other hand, be about to the horizontal fronts that are installed in circuit board such as electrochemical capacitor, like this, the height of the driver diameter that equals electrochemical capacitor adds the thickness of circuit board.These above methods all can not be very little with highly accomplishing, to the tight spot driver that requires is highly arranged, can cause driver to install.
The utility model content
The purpose of this utility model is in order to address the above problem, the fixed structure of a kind of components and parts on circuit board to be provided.
The technical solution adopted in the utility model is: the fixed structure of a kind of components and parts of led driver on circuit board, and described components and parts adopt horizontal mounting structure, and described circuit board is provided with fluting, and the body of described components and parts embeds in the described fluting.
Preferably, described fluting connects the front and back of circuit board, and the insert depth of the body of described components and parts makes the back side of circuit board as the section of components and parts body.
Preferably, described components and parts are the plug-in unit components and parts, and described circuit board only is provided with respectively the corresponding pad of via hole that inserts with each pin for components and parts in the front; The surface-coated of described via hole has metal conducting layer, the pin of described components and parts from the front of circuit board insert with corresponding via hole separately in, described pin is electrically connected by scolding tin with corresponding via hole separately, and be connected by scolding tin with corresponding pad separately, described pin is concordant with the back side of circuit board.
The beneficial effects of the utility model are: the fixed structure of components and parts on circuit board that adopts led driver of the present utility model, on the one hand the height of the height driver of the driver diameter that is lower than components and parts adds the thickness of circuit board, on the other hand, if for the contact pin components and parts then do not comprise the pin length of back of circuit board.Can reduce the height of whole driver so largely, adopt the led driver of this kind fixed structure, when being assembled to it in fluorescent tube, having put and also can guarantee the requirement for height of installing behind the insulating sleeve.
Description of drawings
Fig. 1 shows the fixed structure of components and parts on circuit board of led driver of the present utility model.
Fig. 2 shows the fixed structure of plug-in unit components and parts on circuit board of led driver of the present utility model.
Embodiment
The fixed structure of the components and parts of led driver of the present utility model on circuit board as shown in Figure 1, for leptosomatic components and parts,, can adopt horizontal installation as electrochemical capacitor, differential mode inductance etc., this circuit board 1 is provided with fluting 7, and the body of components and parts 8 embeds in this fluting 7.This fluting 7 is preferably the front 11 and the back side 12 that connects circuit board 1, and the insert depth of the body of these components and parts 8 (by the size Control of fluting 7) makes the back side of circuit board 1 as the section of components and parts body.
As shown in Figure 2, be lower than leptosomatic plug-in unit components and parts 3 for body height, the front 11 of this circuit board 1 is provided with pad 2 around the via hole 4 for 3 configurations of plug-in unit components and parts, the back side 12 of circuit board 1 is not provided with pad around the via hole 4 for the configuration of plug-in unit components and parts, this via hole surface-coated has metal conducting layer 5, the pin 31 of plug-in unit components and parts 3 from the front 11 of circuit board 1 insert with corresponding via hole 4 separately in, this pin 31 is electrically connected by scolding tin 5 with corresponding via hole 4 separately, and is connected by scolding tin 5 with corresponding pad 2 separately.
If these leptosomatic components and parts are the plug-in unit components and parts, its pin can adopt above-mentioned fixed structure equally.
Fixed structure of the present utility model welds realization by the back side at circuit board, and implementation procedure is as follows:
During welding, scolding tin 5 sees through the front 11 that via hole 4 is penetrated into circuit board 1 by the back side 12 of circuit board 1, pin 31 is fully welded, and because the upwards effect of infiltration of scolding tin 5, the soldering tin amount at the back side can be seldom, like this, just the part that can the pin 31 of plug-in unit components and parts 3 be exposed overleaf along the back side 12 of circuit board 1 is all cut (dotted portion of seeing Fig. 1), so, just can reduce the height of built-in drive to greatest extent.If adopt common fixed structure, the solder joint at the back side can be very big, can damage welding when cutting pin, very easily causes rosin joint, is unfavorable for producing.
