Abstract

The utility model discloses a novel transformer framework capable of increasing creepage distance. The novel transformer framework comprises a framework body, a terminal seat and a terminal pin, and a winding groove is formed in the framework body. The novel transformer framework is characterized in that a notch or a boss is arranged on the terminal seat of the framework. Compared with the prior art, the novel transformer framework has the advantages of being simple in structure and capable of effectively increasing the creepage distance of a transformer under the precondition that molding demands of the framework can be met.

Description

A kind of Novel transformer bobbin that increases creepage distance
Technical field
The utility model relates to transformer framework, relates in particular to a kind of Novel transformer bobbin that increases creepage distance.
Background technology
In transformer manufacture technology, the maximum technical limitations that dwindle volume of transformer is exactly the requirement of electrical characteristic.Especially the creepage distance of transformer inside (the being safe distance) one of the main reasons that causes especially volume of transformer to dwindle.
The utility model content
The utility model provides a kind of Novel transformer bobbin that increases creepage distance in order to solve the above-mentioned deficiency of prior art, but its both downsizing volume of transformer also satisfies the safe distance hardware requirement of electrical characteristic.
Above-mentioned purpose of the present utility model realizes by following technical scheme: a kind of Novel transformer bobbin that increases creepage distance, comprise skeleton, terminal base and terminal supportor, described skeleton is provided with winding slot, it is characterized in that: the terminal base of described skeleton is provided with breach or boss, thereby increases the transformer creepage distance that uses this skeleton.
The cross sectional shape of described breach can be combination in any and the distortion of triangle, rectangle, circle or above-mentioned shape.
The cross sectional shape of described boss can be combination in any and the distortion of triangle, rectangle, circle or above-mentioned shape.
Described terminal base can be that the form that increases simultaneously breach and boss exists.The cross sectional shape of breach and boss can be multiple, as combination in any and the distortion of triangle, rectangle, circle or above-mentioned shape.
Described terminal supportor can be combination in any and distortion or the existing transformer terminal shape commonly used of straight type terminal supportor, L-type terminal supportor, straight type and L-type terminal supportor.
The utility model advantage compared with prior art is: the utility model skeleton is satisfying under the prerequisite of its forming requirements, can make simple in structurely, can effectively increase again the creepage distance of transformer.
Description of drawings
Fig. 1 is the structural representation of the utility model the first preferred embodiment.
Fig. 2 is the structural representation of another preferred embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment 1
As shown in Figure 1, a kind of Novel transformer bobbin that increases creepage distance, comprise skeleton 1, terminal base 2 and terminal supportor 3, described skeleton 1 is provided with winding slot 4, it is characterized in that: the terminal base 2 of described skeleton 1 is provided with breach 5, thereby increase the transformer creepage distance that uses this skeleton, the cross sectional shape of described breach 5 is rectangle; Described terminal supportor 3 comprises straight type terminal supportor and L-type terminal supportor.
Embodiment 2
As shown in Figure 2, a kind of Novel transformer bobbin that increases creepage distance comprises skeleton 1, terminal base 2 and terminal supportor 3, and described skeleton 1 is provided with winding slot 4, it is characterized in that: the terminal base 2 of described skeleton 1 is provided with boss 6, thereby increases the transformer creepage distance that uses this skeleton; The cross sectional shape rectangle of described boss 6; Described terminal supportor 3 comprises straight type terminal supportor and L-type terminal supportor.
Above-mentioned embodiment is exemplary, is to be this patent to be comprised the restriction of scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses do anyly be equal to change or modify, all fall into the scope that this patent comprises.
