[Industrial application]

 The present invention relates to a plug-in package in which an electronic circuit is configured in a series-controlled structure, is plugged into a predetermined box-frame type shelf for collective storage, and is mutually and externally connected to configure a device.

Electronic devices must be designed in consideration of productivity and increase mounting efficiency in a given space of a frame. For this reason, in electronic devices with large-sized housings these days, the circuit configuration is performed on a printed wiring board, external connection connectors are provided at the ends, and a plug-in package whose size is standardized is assembled. It is composed of a shelf that is mounted and occupies approximately the width of the cabinet, and the mainstream form is that the shelves are stacked and mounted according to the height of the cabinet.

[0003]

[Prior Art]

 FIG. 4 shows shelf mounting of a conventional plug-in package. As shown in FIG. 4, a plug-in package 39 of a conventional example is composed of a printed board 4 on which components are mounted on one surface, a connector 5 for connecting an external circuit is provided on a rear edge portion, and a front surface is provided on the front surface. When operating parts of parts (variable parts, switches, connection plugs, measuring jacks, etc.) that are operated in the mounted state and status display parts (lamp, LED, instrument, etc.) are installed, and the equipment operator handles them. A face plate 19 is attached to the front plate 19 for easy handling. The front plate 19 is fastened and fixed to the L-shaped metal fittings 6 fixed to the front upper and lower corners of the printed board 4 from the surface with fixing screws 61.

The shelf 9 in which the plug-in packages 39 are collectively mounted has a box-like shape with an open front, and guide rails 91 for guiding the mounting of the printed board 4 face each other on the upper and lower inner surfaces, and are provided parallel to a predetermined pitch. A printed board is fixed on the rear surface (not shown), a connector for plug-in connection with the connector 5 of the plug-in package 39 mounted is arranged at a predetermined position, and the space between the mounted plug-in packages 19 is printed. Interconnected by wiring.

[Problems to be solved by the device]

 However, due to the recent high-density mounting, many notations are required for the front plate 19 depending on the configuration circuit. This notation space increases the width of the front plate 19 and the width of the plug-in package 39 is 1 pitch. More than that. There is no problem in mounting the plug-in package 39 on the shelf 9 in the case of the empty mounting shelf 9, but when it is necessary to mount the plug-in package 39 closely, there is a space between the plug-in package 39 and the adjacent plug-in package 39. Since it is eliminated, it is mounted by covering the protruding portion of the front plate 19 on the front surface of the adjacent plug-in package 39. Furthermore, the adjacent plug-in package 39 has a restriction that it cannot be mounted unless the front plate 19 is provided. Moreover, when taking out the adjacent plug-in package 39 for in-house testing, operation maintenance, etc., take out the plug-in package 39 with the front plate first, or remove the fixing screw 61 if operation is not possible. It cannot be taken out unless the front plate 19 is removed and the position is shifted. Further, the removed front plate 19 has to be reattached, which is poor in workability and requires man-hours. There were problems such as.

In view of such problems, an object of the present invention is to provide a plug-in package that has a wide front plate that does not affect the insertion and removal of the adjacent member and that performs sufficient notation.

[0007]

[Means for Solving the Problems]

 As shown in the principle explanation diagram of Fig. 1, [1] The electronic circuit is configured in a [1] series-controlled structure, plugged into a predetermined box-frame-shaped shelf for collective storage, and for mutual and external connection. This is achieved by the plug-in package 3 of the present invention, which is a plug-in package constituting the device, and in which the outermost front plate 1 is tightly hinged so that it can be rotated forward by a predetermined angle. [2] Also, the front plate 11 is divided into two in the width direction, the half body 11A having a predetermined width is fixed to the main body 2, and the other half body 11B is tightly attached to the half body 11A so that the half body 11A can be rotated forward by a predetermined angle. It is also suitable for the above-mentioned plug-in package 33 of the present invention. [3] Further, it is also achieved by the plug-in package 33 in which the other half body 11B is attached to the front plate 11 with the step 12 provided in front of the half body 11A.

[0008]

[Action]

 That is, as shown in FIG. 1 (a), in the plug-in package 3 using the front plate 1 protruding from the mounting area of the main body 2, the front plate 1 is moved forward by a predetermined angle when the adjacent plug-in package is inserted / removed. Since it can be rotated, it does not interfere with the insertion and removal.

Further, as shown in FIG. 1B, in the front plate 11 divided into two, the width of the half body 11 A fixed to the main body 2 is not more than the pitch width occupied by the internal mounting of the plug-in package 33. If you can pivot the other half 11B that sticks out and covers the next, forward, and if you step it further and hinge it, even if the next is a plug-in package 3, 33 with front plates 1 and 11, Can be opened and stacked.

In view of such a problem, the present invention can provide a plug-in package having a wide front plate that does not affect the insertion and removal of the adjacent member and can perform sufficient notation.

[0011]

【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings. Throughout the drawings, the same reference numerals indicate the same objects. FIG. 2 shows a plug-in package of one embodiment of the present invention, and FIG. 3 shows a plug-in package of another embodiment of the present invention.

This embodiment was carried out for a plug-in package that constitutes an exchange. In both cases, the notation items on the front plates 1 and 11 are increased, and the front plates 1 and 11 extend beyond the mounting area of the main body 2. This is carried out for the packages 3 and 33. One example is a one-sided rotating front plate, and another example is a two-divided folded front plate.

As shown in FIG. 2, the plug-in package 3 of one embodiment has a main body 2 made of a printed wiring board, and on one side of this, components are mounted up to the shaded area in the figure and connected by wiring to form a circuit configuration. The front plate 1 is provided with a connector 5 for plug-in mounting on a shelf (not shown) for circuit connection, and a display part (not shown) is attached to the front part for explaining the description. Is tightly hinged to the main body 2 via a hinge 7 on the right edge in the figure. As a result, the front plate 1 can be pivoted forward to the left and is tight so that it can be fixed at any position.

In the normally mounted state, the front plate 1 is fixed to the front so that the notation is easy to see, but the portion protruding from the mounting area (hatched area in the figure) of the main body 2 is closely packed on the left side (not shown). It covers the front of the plug-in package without the mounted front plate. Therefore, when inserting / removing the plug-in package, the front plate 1 is rotated forward in the mounting state without removing the front plate 1 or removing the package, and the front plate 1 is set in its own mounting area. It can be freely inserted and removed by fixing it in the position.

The other embodiment has a constraint that the package to be mounted next must be a package without a front plate in the above-mentioned one embodiment, but this constraint is removed. The plug-in package 33 is as shown in FIG. 3. Explaining only the parts different from the one embodiment, the front plate 11 is divided into two in the width direction, and the half body 11A is below the self-mounting area (hatched area in the figure). The other half 11B is hinged tightly to the half 11A via the hinge 77, and the step 12 of a plate thickness or more is attached to the front. Installed.

As a result, even if the package to be mounted on the left side (not shown) has the front plate, the other half 11B to be covered has the step 12, so that it should be stacked in front of the adjacent front plate. As with the above, the other half 11B can be freely inserted and removed by pivoting the other half 11B forward and fixing it at a position that fits within its own mounting area.

Each of the above-described embodiments is an example, and the shape of each part and the rotating hinge mechanism are not limited to those described above.

[0018]
