Background

A Transformer (Transformer) is a device that changes an alternating-current voltage by using the principle of electromagnetic induction, and main components are a primary coil, a secondary coil, and an iron core (magnetic core). A transformer applied to electronic products belongs to a small transformer. Such as transformers in televisions, displays. A primary coil and a secondary coil of the miniature transformer are wound on a coil frame, terminals are arranged on the coil frame, and outgoing lines of the primary coil and the secondary coil need to be connected with corresponding terminals.

SUMMERY OF THE UTILITY MODEL

The utility model solves the technical problem that: the lead-out wires of the small transformer coil are prevented from crossing (or called as interference) and contacting.

The wire is wound on the winding part to form coils (including a primary coil and a secondary coil), one coil generally has two leading-out ends, two coils have four leading-out ends, and in actual production, one coil can have more than two leading-out ends. A plurality of terminals are connected to the corresponding terminals, and adjacent or neighboring terminals may be in contact with or cross. For avoiding the emergence of this kind of condition, the utility model discloses set up a plurality of bumps on the terminal microscope carrier, carry on spacingly to a plurality of terminals of drawing forth.

The utility model discloses can avoid the lead-out wire of miniature transformer coil alternately or contact, promote the security of transformer.

fig. 2 is a plan view of the transformer bobbin of fig. 1 viewed from above.

The symbols in the drawings illustrate that:

10. a wire winding portion;

20. a terminal carrier; 21. a terminal; 22. a wire passing groove; 23. an iron core positioning structure; 24. a convex portion;

Detailed Description

With reference to fig. 1 and 2, the transformer bobbin with a limiting structure includes a winding portion 10 on which a coil is wound and a terminal carrier 20 on which a terminal 21 is disposed, and a bump 30 for limiting a leading-out end of the coil is disposed.

The number of the terminal stages 20 is two and is distributed on both left and right sides of the winding portion 10. Two salient points 30 and four terminals are arranged on the left terminal carrying platform, and two salient points and four terminals are arranged on the right terminal carrying platform. Taking the left terminal carrying platform as an example, four terminals are set as a first terminal, a second terminal, a third terminal and a fourth terminal, two bumps are a first bump and a second bump, the first leading-out end is connected with the first terminal, the second leading-out end is connected with the second terminal, and the first bump is arranged between the first leading-out end and the second leading-out end, so that the first leading-out end and the second leading-out end cannot be contacted or crossed; the third leading-out end is connected with the third terminal, the fourth leading-out end is connected with the fourth terminal, and a second bump is arranged between the third leading-out end and the fourth leading-out end, so that the third leading-out end and the fourth leading-out end cannot be contacted or crossed; the first leading-out end and the second leading-out end are arranged in the front left direction, and the third leading-out end and the fourth leading-out end are arranged in the rear left direction. The right terminal carrier principle and the left terminal carrier.

The terminal carrier 20 is provided with a wire passing groove 22, and the coil leading-out end passes through the wire groove and then comes to the surface of the terminal carrier 20 provided with the salient point 30 and is connected with the terminal 21. Taking the left terminal carrying platform as an example, after the four leading-out ends pass through the slot 22, the first leading-out end and the second leading-out end extend towards the left front, and the third leading-out end and the fourth leading-out end extend towards the left rear. The wire guiding groove 22 has a limiting function on the leading-out end, and the position of the leading-out end can be effectively limited by matching with the salient point 30.

One side of the terminal carrying platform 20 is provided with an iron core positioning structure 23, and the iron core positioning structure is bent. According to the prior art, the iron core is formed by splicing two E-shaped iron core pieces, and the iron core is in a shape of a day. The iron core positioning structure is used for positioning the iron core piece, and the iron core is accurately matched with the wire frame. In order to make the matching stable, the matching of the iron core piece and the coil holder is close matching, the iron core piece can extrude the iron core positioning structure 23 of the coil holder, and the iron core positioning structure is deformed. Because the iron core positioning structure is bent, the bent iron core positioning structure is bent according to the bending direction, the wire frame is a plastic piece, and the bending belongs to elastic deformation, so that the smooth and tight matching of the iron core piece and the wire frame is ensured. The other side of the terminal carrying platform 20 is provided with a structure similar to the iron core positioning structure 23, one iron core piece is matched with the wire frame from the top of the wire frame downwards, the other iron core piece is matched with the wire frame from the bottom of the wire frame upwards, and the two iron core pieces are spliced into an iron core.

The salient points 30 are located at two sides of the wire passing groove 22 and between the terminal 21 and the iron core positioning structure 23. After passing through the wire passing groove 22, the leading-out ends are divided into two groups, and one group passes through the salient point 30 on one side of the wire passing groove 22 and then is connected with the corresponding terminal; the other group of salient points passes through the salient points on the other side of the wire passing groove and is connected with the corresponding terminals. Therefore, the leading-out ends are shunted by the wire grooves and then shunted by the corresponding salient points, and contact or intersection among the leading-out ends is effectively avoided.

As a modification, the edge of the terminal carrier 20 is provided with a convex portion 24, and the convex portion and the bump 30 are located on the same plane of the terminal carrier. The terminal is connected with the corresponding terminal after passing through the leading-out end of the corresponding salient point and the corresponding convex part, so that the connection stability of the leading-out end and the corresponding terminal is further improved. The relationship of the terminals to the respective projections may be a winding relationship.

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.
