Abstract

The utility model discloses an ultrathin transformer which comprises a magnetic core and a skeleton, wherein the magnetic core is in an inverted E shape; a groove matched with the magnetic core is formed in the skeleton; pins are arranged at the two side bottoms of the skeleton; the magnetic core is inserted into the skeleton; and the four corners of the top of the magnetic core are chamfers. Compared with the prior art, the ultrathin transformer is more suitable for a semicircular aluminum section of an LED (light emitting diode) lamp as the overall height of the ultrathin transformer is reduced.

Description

A kind of ultra-thin transformer

Technical field

The utility model relates to a kind of transformer, particularly a kind of ultra-thin transformer that uses on the LED light fixture.

Background technology

At present, the arrangement space of the semicircle aluminium section integral body of LED lamp is little, requires supporting electronic devices and components also to the ultrathin development, also is not fit on the market now the transformer of the LED lamp of this semicircle aluminium section bar.

The utility model content

The utility model purpose: for the problem and shortage of the transformer of the LED lamp that is not fit to semicircle aluminium section bar in above-mentioned prior art, the utility model provides a kind of ultra-thin transformer device.

Technical scheme: for realizing above-mentioned utility model purpose, the utility model provides a kind of ultra-thin transformer, comprise magnetic core and skeleton, wherein, described magnetic core is the type of falling E, and the groove that adapts with magnetic core is arranged on skeleton, two side bottoms of skeleton have pin, magnetic core is plugged on skeleton, and wherein, four jiaos of the magnetic core top is chamfering.

In order better to reduce the height of transformer, the pin of skeleton is patch-type.

Further, respectively there are 6 pins the skeleton both sides.

Beneficial effect: compared with prior art, the utility model has not only reduced the height of transformer integral body, and makes transformer be more suitable for the semicircle aluminium section bar of LED lamp.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is for having adopted LED fluorescent tube sectional view of the present utility model.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.

As shown in Figure 1, a kind of ultra-thin transformer comprises magnetic core 1 and skeleton 2, wherein, described magnetic core 1 is the type of falling E, and the groove 3 that adapts with magnetic core 1 is arranged on skeleton 2, and two side bottoms of skeleton 2 have pin 4, magnetic core 1 is plugged on skeleton 2, and wherein, four jiaos of magnetic core 1 top is chamfering.

Wherein, the pin 4 on skeleton 2 is preferably patch-type, can reduce like this height of skeleton integral body.

Further, the pin 4 of skeleton 2 both sides is preferably each 6.

As shown in Figure 2, magnetic core 1 and skeleton 2 form transformer 5, and wherein, transformer 5 is welded on pcb board 6, and transformer 5 and pcb board 6 are arranged in semicircle LED fluorescent tube 7.

Wherein on magnetic core 1, the radian of the radian of chamfering and semicircle LED fluorescent tube 7 adapts.

Gap between the chamfering at magnetic core 1 top and semicircle LED fluorescent tube 7 is more preferably greater than 0.2mm, can guarantee like this transformer 5 and the pcb board 6 semicircle LED fluorescent tube 7 of can packing into very smoothly.
