Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a storage case for electronic components such as printed circuit boards and relays.

"Purpose" The present invention was developed with the aim of assembling electronic components in a compact manner in one place, making it easier to install and manage the electronic components, and making it easier to replace electronic components in the event of an emergency such as a disconnection. It is what was done.

"Means to be Solved by the Invention" In order to achieve the above object, the present invention forms a housing-like case with the openings of a container-shaped left case and a right case facing each other, and the case has the following features: The printed circuit board can be stored by making the connector attached to the periphery of the printed circuit board protrude from the circumferential surface of the case, or
It is configured so that an intermediate case for storing relatively large parts such as relays can be installed between the left and right cases.
A mounting groove for mounting the mounting rail is provided on the bottom of the case.

"Function" Attach the case containing the printed circuit board to the mounting rail, or incorporate an intermediate case that stores relatively large parts such as relays, and attach it to the mounting rail, and connect the electrical connection to the connector protruding from the case. Connecting.

Embodiment FIG. 1 shows an exploded perspective view of a printed circuit board housed in a case.

Electronic components such as resistors, capacitors, coils, ICs, and LSIs are mounted on a rectangular printed circuit board 1, and connectors 2 are attached in a protruding manner on both sides of its periphery. The connectors 2, 2 are connected to electronic components by a pattern. The insulating left case 3 and right case 4 each have a rectangular container shape, with their openings facing each other to form a housing-like case 5. The printed circuit board 1 is placed inside the left case 3, its four corners are screwed and fixed with screws 6, and the opening of the right case 4 is opposed to and abutted against the opening of the left case 3, and the printed board 1 is provided on the contact surface. Connect the protrusions and holes by fitting them together. Window holes 7, 7, 8 are provided in both side surfaces and the top surface of a case 5 formed by combining a left case 3 and a right case 4, and connectors 2, 2 are made to protrude from the window holes 7, 7, respectively. Further, the window holes 7, 7 can be closed with side covers 9, 9, and the window hole 8 can be closed with a top cover 10. A mounting groove 11 for mounting the mounting rail is provided on the bottom surface of the case 5.

The connector can be made to protrude from any of the three surfaces, including both sides and the top surface of the case 5, and the connector 2 can be used as a fitting.
In addition to wrapping, wrapping can also be used.
Fig. 2 shows an example in which the connector 2 protrudes from both sides of the cover 5, Fig. 3 shows an example in which the connector 2 protrudes from one side and the wrapping 31 from the top surface, and Fig. 4 shows an example in which the connector 2 protrudes from the top surface only. This is an example in which the connector 2 is protruded.

Figure 5 shows how the printed circuit board 1 is stored and the connector 2
This shows an example in which a large number of protruding cases 5 are fitted onto the mounting rail 12 in a stacked manner, and fixed by screwing the fixture 13 with the screw 14.

6 to 9 similarly accommodate the printed circuit board 1,
This is an example in which a large number of cases 5 each having a protruding connector 2 are stacked one on top of the other and are fitted and fixed to a mounting rail.

Figure 10 shows the relay 21 between the left and right cases 3 and 4.
This is an example that incorporates an intermediate case that stores the.

"Effects of the Invention" Since the present invention has the above-described configuration and operation, electronic components can be assembled in one compact place, making it easy to install and manage the electronic components. Furthermore, electronic components can be easily replaced in the event of an emergency such as a disconnection.
