Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an object to provide an electronic circuit device case equipped with a terminal case in an electronic circuit device including a high voltage transformer used in a copying machine or the like.

[0002]

2. Description of the Related Art Conventionally, electronic circuit devices including high-voltage transformers used for copying machines are generally manufactured by dividing the case into a main body case and a terminal case. After storing the necessary electronic circuit equipment, attach the terminal case to the main body case and connect it, connect the output of the electronic circuit equipment so that it can be taken out from the terminal stored in the terminal case, and then the main body containing the electronic circuit equipment The inside of the case is molded with resin to form a molded electronic device in which the main body case and the terminal case are integrated.

When the electronic circuit device is a high voltage transformer, the primary side bobbin of the transformer is fixed in the case of the main body by interposing a simple spacer or the like between the case and the inside of the case. When the output from the board is taken out to the terminal, an output line is separately connected to the output part of the electronic component mounted on the printed board, and the output line is soldered to the terminal of the terminal case to take out the output.

[0004]

However, in the manufacturing method in which the main body case and the terminal case are separately assembled before they are separately manufactured and molded as described above, the following drawbacks occur. Was there.

That is, when mounting and assembling the terminal case to the main body case, a notch groove having a substantially U-shape is formed on the side wall of the main body case, and the connecting plate erected on the terminal case is fitted into the U-shape notch groove. Since it is attached by mounting, when the connecting plate is fitted, the connecting plate expands the notch groove to make a gap, and when molding in the main body case, the resin leaks from the gap and the molding resin flows out of the case, There is a drawback that wasteful labor is required to peel off the leaked resin.

On the other hand, if the main body case and the terminal case are previously formed as an integral case, the above-mentioned drawbacks can be solved, but the volume of the connection between the electronic circuit device in the main body case and the terminal in the terminal case is small. It will be done in the main body case of, and it will require a lot of labor for its assembly work,
The drawback is that it is against the miniaturization of equipment.

Further, in the electronic circuit equipment housed in the main body case, for example, when the electronic circuit equipment is a high-voltage transformer, the bobbin on the primary side or the secondary side and the printed circuit board forming the transformer are placed in the main body case before molding. Although the assembly is performed, the posture of the printed circuit board becomes unstable in the main body case at the time of molding, and the arrangement position is displaced or tilted at the time of molding, which makes it difficult to perform reliable assembly.

That is, there is a drawback that the connecting work between the primary and secondary bobbins and the printed circuit board is complicated and the connecting structure is unstable, which makes it difficult to maintain a stable posture during molding. .

Further, the connection between the printed circuit board and the terminal in the terminal case is performed by connecting the output line from the printed circuit board,
Since the terminals are connected by soldering, the volume is increased by the amount of the output wire, which hinders downsizing, and an unnecessary output wire is required, so that the connection work is complicated.

It is an object of the present invention to provide an electronic circuit device case equipped with a terminal case that can solve the above problems.

Conventionally, the high-voltage transformer C housed and molded in the main body case A has a bobbin arranged on the front surface side of the blind substrate 10 and electronic parts arranged on the rear surface side thereof.
Therefore, since the bobbin and the electronic components are arranged with the printed circuit board interposed therebetween, the entire volume of the high voltage transformer is large, which is a drawback of miniaturization.

In the present invention, by mounting the primary and secondary bobbins 12 and 11 and the electronic component 14 on the surface side of the printed circuit board 10, the entire high voltage transformer section C can be miniaturized as much as possible. Moreover, in the output section of the high voltage transformer section C, the volume of the high voltage transformer section C can be reduced by directly connecting the output lead wire 34 to the terminal base end of the terminal case B.

Furthermore, the resin can be completely prevented from leaking at the time of molding, and can effectively function as a high-voltage transformer of a copying machine.

[0048]

The present invention has the following effects.

That is, since the engaging edge is formed on the side end surface of the connecting plate of the terminal case fitted into the cutout portion of the main body case, when the connecting plate is fitted into the cutout portion, the engaging edge engages with the cutout portion. It is possible to prevent the notch portion from expanding due to engagement with the mating collar, and prevent leakage of the resin molded in the main body case.

Further, right and left engaging projections are provided on the side of the cutout portion of the body case, and recesses are formed on the side end surfaces of the connecting plates of the terminal case so that they engage with each other. Prevents the notch part from expanding.

Further, in the structure in which the high-voltage transformer as an electronic circuit device is housed in the main body case, the upper end of the primary side bobbin of the high-voltage transformer and the inner surface of the main body case are engaged and fixed by the overhanging protrusion and the engaging protrusion. As a result, the position of the primary bobbin can be fixed easily and surely, and when the lower end of the primary bobbin is fitted into the iron core insertion hole on the bottom surface of the main body case, the iron core insertion hole is lowered. Since the inclined surface has a narrowed shape, the lower end of the primary side bobbin and the iron core insertion hole of the main body case are brought into close contact with each other, so that the bobbin can be fixed in position and leakage of the mold resin can be prevented.

Further, since the primary side leg and the secondary side leg are connected to the primary side bobbin and the secondary side bobbin, respectively, when mounting each bobbin on the printed circuit board, the engaging groove and the engaging vertical groove of the circuit board are mounted. Since it suffices to engage each leg body, there is an effect that the mounting work becomes simple and the position setting at the time of molding can be surely performed.

Further, each bobbin and other electronic device parts are arranged on the front side surface of one side of the printed circuit board, and the back side surface of the other side of the board is closely adjacent to the inner side surface of the main body case. In order to store the printed circuit board in the case,
It has the effect of downsizing the body case, and further, because of this downsizing, the output lead wires of electronic device parts can be directly connected to the terminal base end of the terminal case, and no separate output wire is required. The advantage is that the space inside the small body case can be effectively used.

As described above, according to the present invention, there is an effect that the assembling is easy and reliable and the main body case can be miniaturized as much as possible.
