Abstract

PURPOSE:To standardize parts of electronic apparatus easily, and to improve the productivity by forming a notch in the sidewall of an insulating case, in which the electronic part is incorporated, and detachably combining a terminal case with the notch. CONSTITUTION:A notch 6 is shaped to the sidewall of an insulating case 5 in which various electronic parts 4 constituting a high-tension transformer, a rectifier circuit and a control circuit are incorporated. On the other hand, a combining section 9 consisting of a fitting section 9a fitted to the notch 6 and a slip-off preventive section 9b having an external shape larger than the fitting section 9a is shaped to a terminal case 8 building in an output terminal 7 for said high-tension transformer 4. The terminal case 8 is coupled with the insulating case 5, and connected to the output terminal 7 by a lead 11 for connection, and an insulating agent 10 is casted. Accordingly, even when the insulating case 5 in which the high-tension transformer 4 is incorporated is the same, only the shape of the terminal case 8 building in the output terminal 7 for the high-tension transformer 4 is changed, thus constituting high-tension transformer blocks having any shapes.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to electronic equipment such as power supplies used in office equipment and the like.

2. Description of the Related Art Conventionally, this type of electronic equipment has had a structure as shown in FIG.

In FIG. 4, a storage section 1 that stores electronic components that constitute a transformer, a rectifier circuit, and a control circuit assembled on a printed circuit board and its terminal section 2 are integrated by an insulating case 3. was.

Problems to be Solved by the Invention However, with such a conventional structure, the insulating case 3 must be changed each time the shape of the terminal portion 2 changes, making it impossible to standardize the product, which not only improves productivity but also increases quality costs. It is a big problem in terms of

The present invention is intended to solve these problems, and aims to maximize the standardization of electronic component storage units, improve productivity, improve quality, and reduce costs.

Means for Solving the Problem In order to solve this problem, the present invention provides a notch in the side wall of the insulating case, and a fitting part that fits into the notch and a fitting part that fits into the notch at the end of the cylindrical body containing the terminal. The terminal case is configured to be coupled to the insulating case, and the terminal case is provided with a coupling portion consisting of a retaining portion having a larger outer diameter than the coupling portion.

Function As described above, by using both the insulating case and the terminal case, not only can the insulating case be standardized, but also it is possible to correspond to any output terminal shape simply by changing the terminal case.

EXAMPLE Hereinafter, an actual foil example of the present invention will be explained based on all the attached factors.

In FIGS. 1 and 2, a notch 6 is provided in the side wall of an insulating case 6 incorporating a high voltage transformer and various electronic components 4 constituting a rectifier circuit and a control circuit, and a notch 6 is provided in the side wall of the insulating case 6 in which a high voltage transformer and various electronic components 4 constituting a rectifier circuit and a control circuit are incorporated. A terminal case 8 in which the case 8 is provided with a connecting portion 9 consisting of a fitting portion 9a that fits into the notch 6 and a retaining portion 9b having a larger outer diameter than the other fitting portion? combined with the insulating case 5 incorporating the high voltage transformer 4,
Connect to the output terminal 7 using the connecting lead wire 11 and insulating material 1.
It is made by casting 0.

With the above configuration, even if the insulating case 6 incorporating the high voltage transformer 4 is the same, a high voltage transformer block of any shape can be constructed by changing only the shape of the terminal case 8 containing the output terminal 7 of the high voltage transformer 4. Moreover, since the high-voltage transformer 4 and insulation case 6, which are the most important in terms of quality, are standardized, high-quality, low-cost products can be produced: - Not only that, but productivity can also be improved.

In addition, since a groove 13 is provided in the connecting part 9 of the terminal case 8 (()) through which the connection IJ-wire 11 is passed, if the insulation case 5 is filled with 10 pieces of insulating material, this groove 13 will also be formed in the terminal case 8.
When this insulating material 10 flows through and hardens, the whole is integrated.

Next, another embodiment of the present invention is shown in FIG. 3 of the accompanying drawings.

This will be explained with reference to FIG. By replacing the terminal case 8 shown in FIG. 1 with the bushing 12 shown in FIGS. 3 and 4, the output of the high voltage transformer 4 can also be taken out through the lead wire 16.

The bushing 12 is provided with a fitting part 142L that fits into the notch 6 of the insulating case 5, and a retaining part 14bi which has a larger outer diameter than the fitting part 142L. Line 16'ff: Penetrate. By combining the bushing 12 and the insulating case 5, the output of the high voltage transformer 4 can be taken out through the lead wire 16 without leaking the insulating agent 10 cast into the insulating case 5.

Effects of the Invention As described above, in the electronic device of the present invention, a notch is provided in the side chamber of the insulating case in which the electronic component is incorporated, and a fitting portion that fits into the notch and this fitting portion are provided at the end of the cylindrical body containing the terminal. By joining a terminal case with a connecting part consisting of a larger outer diameter retaining part to the above-mentioned insulating case, it is possible to easily standardize electronic equipment parts, improve reliability, productivity, reduce costs, and facilitate mass production. This has the effect of dramatically shortening the lead time when transitioning to a new system.
