Abstract

PURPOSE:To facilitate the connection or a secondary winding, and prevent disconnection, by inserting one end of a nearly L-shaped lead, the other end of which is led out in a case fixing part, into a cylindrical terminal with which the secondary winding is connected. CONSTITUTION:A transformer case 1 is equipped with the following; a penetrating hole 6, a protruding part 7, a side wall 8, and a groove 2 formed by an inner wall 9. A cylindrical lead terminal 3 around which a secondary winding 4 is wound is accommodated in the groove 2, and a nearly L-shaped lead terminal 5 is inserted into the penetrating hole 6 and connected with the lead terminal 3. Since, in this manner, the nearly L-shaped lead terminal 3, whose one end us led out in a case fixing part, is inserted into the cylindrical lead terminal 3 with which a secondary winding 4 is connected, a transformer 1 wherein the connection of the secondary winding 4 is easy and the disconnection of the secondary winding 4 is not caused can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a transformer that facilitates attachment of lead terminals to prevent disconnection of a secondary winding.

(Prior Art) The structure of a conventional transformer lead terminal installation is as follows.

In other words, the lead terminals are installed in the grooves of the transformer case,
After that, the secondary winding is connected.

(Problems to be Solved by the Invention) In such a conventional structure, since the secondary winding is connected while being attached, it is difficult to attach the secondary winding.

In addition, after connecting the secondary winding to the lead terminal, the mold is mounted, but at that time, depending on the connection state of the secondary winding, pressure may be applied to the connection part between the lead terminal and the secondary winding, and the secondary winding There was a risk that this could lead to wire breakage.

An object of the present invention is to provide a transformer that allows easy connection of the secondary winding and prevents disconnection of the secondary winding.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above object, the present invention provides an abbreviated lead terminal whose one end is pulled out at a mounting section provided in a case housing a transformer main body.

The case mounting consists of a cylindrical lead terminal to which the secondary winding from the transformer body is connected and the other end of the abbreviated lead terminal is inserted.

(Function) In such a configuration, the case is installed by inserting the other end of the III-shaped lead terminal, one end of which is closed, into the cylindrical lead terminal to which the secondary winding is connected. Wire connection is easy and disconnection of the secondary winding can be prevented.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the structure of lead terminal attachment of a transformer according to the present invention.

1 is a transformer case in which a groove 2 is provided.

A cylindrical lead terminal 3 is attached to the groove 2 with a secondary winding 4 wound thereon.

5 is an abbreviated lead terminal which is inserted into and connected to the cylindrical lead terminal.

FIG. 2 is an enlarged view of the grooves in the transformer case of FIG. 1;

The groove 2 has a through hole 6, a protrusion 7, a side wall 8, and an inner wall 9.

The abbreviated lead terminal 5 is inserted into the through hole 6. The abbreviated lead terminal 5 and the cylindrical lead terminal 3 are connected to the protrusion 7
The size is such that it can be accommodated within the area formed by the side wall 8 and the inner wall 9.

That is, since the through hole 6 is provided in the groove 2 between the protrusion 7 and the side wall 8, the dimensions of the abbreviated lead terminal 5 are determined, and the dimensions of the cylindrical lead terminal 3 are determined by the area of the side wall 8 and the inner wall 9.

The cylindrical lead terminal 3 with the secondary winding 4 wound thereon is stored in the groove 2, and the oval-shaped lead terminal 5 is inserted into the through hole 6. Connect lead terminal 5.

〔Effect of the invention〕

In this way, the present invention allows for easy connection of the secondary winding because the case is mounted by inserting an abbreviated lead terminal with one end pulled out into the cylindrical lead terminal to which the secondary winding is connected. A transformer that does not cause disconnection of the secondary winding can be obtained.
