Abstract
The utility model discloses a welding structure for plug-in components of an LED driver on a circuit board. Pads respectively corresponding to through holes are arranged only on the front surface of the circuit board; pins of the plug-in components are inserted into the through holes; a metal conducting layer is coated on the surface of each through hole; the pins of the plug-in components are inserted into respectively corresponding through holes from the front surface of the circuit board; the pins are electrically connected with the respectively corresponding through holes by the aid of soldering tin and fixedly connected with the respectively corresponding pads by the aid of soldering tin; and the pins are parallel and level to the back surface of the circuit board. In the circuit board welding structure of the LED driver, the height of the driver is exclusive of the lengths of the pins on the back surface of the circuit board, so that the height of the integral driver is reduced to a larger extent and installation of a tube lamp driver is facilitated.
Description
Technical field
The utility model relates to led driver, relates in particular to the Welding Structure of plug-in unit 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 Welding Structure of a kind of plug-in unit components and parts on circuit board to be provided.
The technical solution adopted in the utility model is: a kind of Welding Structure of plug-in unit components and parts on circuit board of led driver, described circuit board only are provided with respectively the corresponding pad of via hole that inserts with each pin for the plug-in unit components and parts in the front; The surface-coated of described via hole has metal conducting layer, the pin of described plug-in unit 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: adopt Welding Structure of the present utility model, the height of driver does not comprise the pin length of back of circuit board, reduced the height of whole driver largely, adopt the welded led driver of this kind, when being assembled to it in fluorescent tube, putting and also can guarantee the requirement for height of installing behind the insulating sleeve.
Description of drawings
Fig. 1 shows the Welding Structure of plug-in unit components and parts on circuit board of led driver of the present utility model;
Fig. 2 shows the fixed structure of components and parts on circuit board of led driver of the present utility model.
Embodiment
The Welding Structure of plug-in unit components and parts on circuit board of led driver of the present utility model as shown in Figure 1, 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.
For leptosomatic components and parts, as electrochemical capacitor, differential mode inductance etc., can adopt horizontal installation, in the present embodiment, as shown in Figure 2, 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.If these leptosomatic components and parts are the plug-in unit components and parts, its pin can adopt above-mentioned Welding Structure equally.
Welding Structure of the present utility model is welded 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 Welding 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.
Claims (1)
1. the Welding Structure of plug-in unit components and parts on circuit board of a led driver is characterized in that: described circuit board only is provided with respectively the corresponding pad of via hole that inserts with each pin for the plug-in unit components and parts in the front; The surface-coated of described via hole has metal conducting layer, the pin of described plug-in unit 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.
