Abstract

The utility model discloses a special-shaped transformer, including primary winding and secondary, primary is the copper sheet, and the secondary coiling is on the skeleton, and primary and secondary adjacent setting, primary and secondary location are in the constant head tank of bed frame. The utility model discloses a copper sheet after the shaping is as primary, and secondary winding coiling is on the skeleton, and the constant head tank is fixed a position primary and secondary that the combination is in the same place, and the iron core passes primary and secondary and fixes a position on the bed frame. Therefore, the special-shaped transformer different from the existing transformer is formed. Compare in current transformer, special-shaped transformer simple structure, the preparation is convenient, does benefit to production efficiency's improvement.

Description

Special-shaped transformer

Technical Field

The utility model relates to a transformer, concretely relates to electronic product's miniature transformer.

Background

According to the prior art, a transformer, including a small-sized transformer used in electronic products, generally includes a bobbin, a primary winding and a secondary winding wound around the bobbin, and an iron core passing through the windings. Wherein, be equipped with the terminal (PIN) of being connected with the winding terminal of drawing forth on the skeleton.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the structure of the small transformer is simplified.

In order to solve the technical problem, the utility model provides a following technical scheme: the special-shaped transformer comprises a primary winding and a secondary winding, wherein the primary winding is a copper sheet, the secondary winding is wound on a framework, the primary winding and the secondary winding are arranged adjacently, and the primary winding and the secondary winding are positioned in a positioning groove of the base frame.

The utility model discloses a copper sheet after the shaping is as primary, and secondary winding coiling is on the skeleton, and the constant head tank is fixed a position primary and secondary that the combination is in the same place, and the iron core passes primary and secondary and fixes a position on the bed frame. Therefore, the special-shaped transformer different from the existing transformer is formed.

Detailed Description

The special-shaped transformer comprises a primary winding and a secondary winding, wherein the primary winding is a copper sheet, the secondary winding is wound on a framework 10, the primary winding and the framework are arranged adjacently, and the primary winding and the framework are positioned in a positioning groove of the base frame.

The copper sheet as the primary winding is a formed copper sheet, the whole copper sheet is in a circular ring shape, and the periphery of the copper sheet is provided with a leading-out end connected with an external lead.

The side wall of the copper sheet is provided with a first positioning structure, and the side wall of the framework 10 is provided with a second positioning structure which can be matched with the first positioning structure. The first positioning structure is matched with the second positioning structure, and the adjacent copper sheets and the framework are positioned with each other and are stabilized in the positioning grooves of the base frame.

The first positioning structure comprises a limiting groove and a stopping structure, and with reference to fig. 2 and 6, the second positioning structure comprises a limiting convex part 11 matched with the limiting groove and a protruding part 12 abutted against the stopping structure. Wherein, the stop structure can be a convex structure which laterally protrudes out of the copper sheet. The number of the limiting convex parts and the number of the protruding parts can be several, and correspondingly, the number of the limiting grooves and the number of the stopping structures are several.

A wire clamping groove 13 is formed in the side wall of the framework 10, and the leading-out end of the secondary winding is clamped in the wire clamping groove and limited by a bending part 14 at the opening of the wire clamping groove. Skeleton 10 for no terminal skeleton, be different from having the terminal skeleton among the prior art, the structure is retrencied more.

The number of primary windings is several, and the number of secondary windings is several. Alternatively, the number of primary windings is four and the number of secondary windings is three, and accordingly, the number of bobbins is three. The four primary windings, namely four copper sheets, and the three frameworks are arranged in a way of copper sheet-framework-copper sheet to form an integral structure, the integral structure is matched in the positioning groove of the base frame, the copper sheets on two sides of the integral structure are matched with two sides of the positioning groove, and the iron core passes through the base frame and all the copper sheets and the frameworks therein to form the special-shaped transformer.

The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
