Abstract

PURPOSE:To reduce accidents of damage from a fire for soldering by joining plural bobbins integrally with a hinge body and reducing the number of built-in circuits of bobbins, twining of windings around terminal metal fittings, and the number of soldering positions to facilitate the work. CONSTITUTION:Two bobbins 2 are coupled integrally by a hinge body 2a, and a coil 3 is wound around this joined to constitute a U-type core 4, and this core 4 is built in a case 1. In such a case, two bobbins 2 are bent in the position of the hinge body 2a and are formed into one bar, and the coil 3 is wound around the whole of bobbins and a start point 3b and an end point 3b of the winding are connected to terminal metal fittings 5, and therefore, bobbins are joined integrally by the hinge body 2a and are not separated. Since the coil is wound around the whole of bobbins, it is unnecessary to connect coils in bobbins by soldering or the like. That is, the number of times of bobbin building-in is reduced and twining of the winding around terminal metal fittings and the number of soldering positions are reduced to facilitate the work, and the accidents of damage from a fire for soldering are reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a convergence yoke device used in a color television receiver or a color display device.

[Conventional technology]

The conventional convergence yoke device has a U-shaped core, but
Each bobbin is separate, and when they are placed in a case and attached to form a core, it takes as many times as there are bobbins, and consideration has not been given to making it possible to attach them at -degrees. In addition, since the Ichigan applied to the bobbin was done individually for each bobbin, there were no unnecessary
was also needed.

Incidentally, related conventional examples of this type of convergence yoke device include, for example, Japanese Utility Model Publications No. 56-18055 and Japanese Utility Model Publication No. 56-18056.

[The problem that the invention is trying to solve]

In the above conventional technology, when configuring the core that includes the convergence yoke, it is necessary to incorporate the bobbins the same number of times as the required number of bobbins, and a large number of connection terminals are also required, so that workability is not considered. Because there was no such thing, there was an open chain that was prone to assembly and wiring mistakes.

The purpose of the present invention is to reduce the number of times the bobbin is assembled during manufacturing, reduce the number of windings on the terminal fittings, and reduce the number of soldering points, making the work easier, and reducing the risk of burnout accidents during soldering. An object of the present invention is to provide a convergence yoke device that can be minimized.

[Means for solving problems]

The above purpose is that if multiple bobbins are connected and integrated with a bendable hinge body, they can be assembled at once, and
If the winding is done through all the integrated bobbins, there is no need to connect the coils between the bobbins, and the number of soldering operations is reduced. Ru.

[Effect]

By connecting the bobbins to each other with a hinge body and integrating them, the core can be assembled in one go. In addition, by winding the coil through multiple integrated bobbins, the entire bobbin can be used at the beginning of winding and at the end of winding.
The present invention will now be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing the entire convergence yoke device as an embodiment of the present invention. In the same figure, 1 is a case, 2 is a bobbin, 2 & is a hinge body, 3 is a coil, 3
m is a coil passing portion between bobbins, 3b is a winding start and winding end portion, 4 is a core, and 5 is a terminal fitting.

In Fig. 1, the bobbins 2 are connected to each other by the hinge body 2&, and a 3ft coil is wound through the U.
2 is a top view showing only the bobbin from FIG. 1, with only the bobbin removed.

It will be appreciated that the bobbins 2 and 2 are joined by the hinge body 2a and are integrated.

In Figure 3, the two bobbins are bent at the hinge body 2a to form a single rod, a coil 3 is wound around the entire rod, and the starting and ending points of the winding are connected to the terminal fitting 5. It shows how it was done. Since the bobbin is integrated with the hinge body 2&, the bobbin will not come apart. Furthermore, since the entire coil is wound through, there is no need to solder or otherwise connect the coils between the bobbins.

From the wound state shown in FIG. 3, it is bent back to the original U-shape shown in FIG. 2 at the hinge body 2& and then placed in the case 1 shown in FIG.

According to this embodiment, the soldering work can be reduced and the work of assembling the bobbins as cores can be done at once for two bobbins at the same time, which is effective in improving work efficiency.

The fourth example shows the case where three bobbins are used with an E-type core.
It is shown in Fig. and Fig. 5.

It will be easily understood that FIG. 4 corresponds to FIG. 2 and FIG. 5 corresponds to FIG. 3. The present invention is also applicable to other transformers.

〔Effect of the invention〕

According to the present invention, when assembling the convergence yoke device, since the plurality of bobbins are integrated with the hinge body, the coil can be wound through the entire body, eliminating half of the winding work. , it has the effect of improving work efficiency.
