Abstract
The utility model provides a transformer for a charger power. The transformer for the charger power comprises a framework, a coil and a magnetic core, wherein the framework comprises a magnetic core accommodating part; the coil is wound on the framework; the magnetic core is arranged in the magnetic core accommodating part of the framework; an arc-shaped boss is arranged on the framework; and a fly wire of the transformer bypasses the boss. According to the utility model, through the arc-shaped boss arranged on the framework, the fly wire can be prevented from being damaged due to bending; and the transformer for the charger power has the characteristics of simple structure and low cost.
Description
Technical field
The utility model relates to a kind of transformer, particularly a kind of transformer of charger power supply.
Background technology
Transformer of the prior art comprises magnetic core, coil, skeleton etc.Wherein, coil winding on skeleton, the magnetic core skeleton of packing into, finished product is processed in impregnation after test electrically.The skeleton PIN1-4 side roof part of transformer of the prior art is provided with boss; The longer dimension of boss and corner angle are arranged; When fly line is walked around boss; Easily because of bending makes fly line impaired, thereby cause the safe distance between impaired place and the primary coil to diminish, produce withstand voltage bad or withstand voltage bad hidden danger.
The utility model content
The purpose of the utility model provide a kind of simple in structure, cost is low, can prevent fly line bending transformer impaired, the charger power supply.
For addressing the above problem, the utility model provides a kind of transformer of charger power supply, comprising: skeleton, skeleton comprise the magnetic core accommodation section; Coil, coil is on skeleton; Magnetic core, magnetic core are installed on the magnetic core accommodation section of skeleton; Skeleton is provided with the boss of circular arc, and the fly line of transformer is walked around boss.
Further, coil comprises primary coil and secondary coil, and boss is arranged on the side near primary coil of skeleton.
Further, fly line is secondary fly line.
The utility model can prevent that through being arranged on the boss of the circular arc on the skeleton fly line is impaired because of bending, has characteristics simple in structure, that cost is low.
Description of drawings
Fig. 1 is the structural representation of the skeleton of the transformer in the utility model.
Fig. 2 is the cutaway view of the utility model.
Embodiment
As illustrated in fig. 1 and 2, the transformer of the charger power supply in the utility model comprises: skeleton 10, and skeleton 10 comprises the magnetic core accommodation section; Coil, coil is on skeleton 10; Magnetic core, magnetic core are installed on the magnetic core accommodation section of skeleton 10; (particularly at the PIN1-4 of skeleton 10 side roof part) is provided with the boss 11 of circular arc on the skeleton 10, and the fly line of transformer is walked around boss 11.Preferably, coil comprises primary coil and secondary coil, and boss 11 is arranged on the side near primary coil of skeleton 10.Preferably, fly line is secondary fly line.
As shown in Figure 1, inferior line fly line is walked around the boss of skeleton PIN1-4 side, thereby makes time line fly line can be not impaired because of bending, has guaranteed the bending part of inferior line fly line and the insulation between the primary coil simultaneously, has strengthened the insulation property of product.When the utility model is applied to charger, can prevent to cause withstand voltage bad and make the out-of-work problem of entire circuit by transformer.Especially, when the utility model is applied to the charger power circuit, can bear the input power supply of 85V/47HZ-264V/63Hz, 1A at least fully, become the out-put supply that converts thereof into 5V/DC, 0.75A.
