Abstract

The utility model discloses a transformer structure, wherein a wire penetrating hole is arranged on an external bobbin winder bracket, an inner bobbin winder bracket is installed on the wire penetrating hole of the external bobbin winder bracket, a ventilating hole and a wire penetrating hole are further arranged on the inner bobbin winder bracket, two E-shaped iron cores penetrate through the wire penetrating hole of the inner bobbin winder bracket, since the transformer structure is composed of two independent coil structures which are combined, a primary coil and a secondary coil do not need separating through insulation paper, the primary coil and the secondary coil share one iron core, the transformer bobbin winder bracket of the utility model has simple structure and convenient assembly, the ventilation and heat dissipation effect between the primary coil and the secondary coil is excellent, the cost is low, and the transformer structure can be widely applied in production and application.

Description

A kind of transformer device structure

Technical field

The utility model relates to a kind of electric component, specifically a kind of transformer device structure of Zhiing.

Background technology

Existing miniature transformer must prevent to stride between the coil level electric leakage with the insulating paper separation between primary coil and secondary coil, insulating paper damages the use that will influence whole transformer, existing transformer device structure complexity, thus very inconvenience when production and assembly, and ventilation is not freely dispelled the heat bad.

The utility model content

The purpose of this utility model provides a kind of insulation easy to assembly and the better transformer device structure of radiating effect.

The utility model is realized by following scheme:

A kind of novel transformer, outer drum stand has a through wires hole, and interior drum stand is installed in the through wires hole of outer drum stand, and interior drum stand also is provided with ventilating opening and a through wires hole, and the through wires hole of drum stand in two E font iron cores are arranged in is in conjunction with forming the loop.

After adopting such structure, enamelled wire is respectively on inside and outside two drum stands, form two independently coils, inside and outside drum stand adopts the plastics of insulation to make, insulation effect is better, result of ventilating heat dissipation between primary coil and secondary coil is good, simplifies transformer device structure and is convenient to assembling, has also simplified the flow process of transformer making and has saved cost.

Description of drawings

With embodiment the utility model is described in further detail with reference to the accompanying drawings below.

Fig. 1 is the structural representation of the utility model transformer.

1, iron core; 2, interior drum stand; 3, outer drum stand.

Embodiment

As shown in Figure 1, novel transformer structure described in the utility model, enamelled wire respectively around interior drum stand (2) and outside on the drum stand (3), interior drum stand (2) is installed in the through wires hole of outer drum stand (3), interior drum stand (2) is provided with ventilating opening and a through wires hole, the intermediate projections of two E font iron cores (1) is arranged in the perforating of interior drum stand (2), and the outer projection of two E font iron cores (1) is in conjunction with forming the loop.

Drum stand (2) and outer drum stand (3) all adopt ambroin to be made to have saved with insulating paper separation primary coil and secondary coil and insulation effect better in the utility model transformer, interior drum stand (2) and outer drum stand (3) can be assembled or take apart easily, have optimized overall structure and have also reduced manufacturing cost simultaneously.

Claims

1. novel transformer structure, it is characterized in that: interior drum stand (2) is installed in the through wires hole of outer drum stand (3), interior drum stand (2) has ventilation hole and through wires hole, and two iron cores (1) are arranged in the through wires hole of interior drum stand (2), is combined into a complete transformer.
