JPS5855813Y2 - Structure of supervisory control unit of multiplex radio equipment - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to the structure of a supervisory control section of a multiplex radio device.

Each unit is equipped with a supervisory control unit that monitors and controls multiple transmitters and receivers, as well as the functional operations of these multiple transmitters and receivers, switches between working and standby units, and has communication lines (order wires). The transmitting/receiving section of the multiplex radio device is configured by installing and wiring the units.

The supervisory control section is the only operating section in the line receiving section of the multiplex radio device, and also serves as a display section for functional operation status.

Therefore, it is desirable that the front side of the supervisory control section has a large area and that the necessary parts are arranged so that they can be easily operated and displayed.

However, the structure of conventional monitoring and control units consists of a box-shaped housing with an open front, and a plurality of wired multi-pole connectors arranged side by side inside the back of the housing, each serving as an operation display section from the front of the housing. A plurality of printed boards each having a front surface plate can be plugged into the connectors mentioned above, or only the printed boards can be plugged in and the operation display can be displayed separately on a single wide front board that fits on the front of the main body of the housing. Some models are designed to attach a front plate with a front panel, but in the former type, parts are attached directly to the printed board near the front plate, and the arrangement of parts is restricted to make electrical connections, so it is difficult to arrange them appropriately. Moreover, in the latter case, it is extremely complicated because it requires wiring between the connector and the parts on the front panel using a large number of east wires.

Furthermore, there are other problems such as the need for connectors for plugging in the printed circuit boards or the need for a mother printed board in place of the connectors.

The purpose of this invention is to solve the above-mentioned problems, and the monitoring and control unit housing is comprised of a housing body, a front plate that can be opened and closed with a door structure in the lateral direction of the housing body, and an inner side of the front plate. A printed board is attached along the side surface, and a card print storage case is provided in which a card printed board is inserted into the surface of the printed board toward the back of the housing body. A mother printed board for the card printed board is formed on at least a part of the printed board, and circuit components for operation and display from the front board are mounted on the printed board. .

An embodiment of the present invention will be described below with reference to the drawings.

The figure is a schematic perspective view showing the front panel (decorative panel board) of the monitoring and control unit opened, and shows the hinges 2 provided on the side of the box-shaped housing body 1 with the front side open. This hinge 2
A front plate 3 that fits the front surface of the housing body 1 and can be opened and closed with a door structure, a Punto board 4 attached to the inner surface 31 of this front plate 3 parallel to the surface, and furthermore, a main part of this printed board 4. A card printed board storage case 5 is attached toward the back side of the housing body 1.

Although the card printed board storage case 5 is not shown in detail, it is made up of a plurality of required card printed boards 6 for control circuits.
A guide rail is provided so that the card can be inserted toward the printed board 4, and a mother printed board part is formed on the surface of the printed board corresponding to the guide rail so that a card printed board 6 can be connected by plug-in. Both the printed board 4 and the case 5 are housed inside the housing body 1 when the front plate 3 is closed around the hinge 2 in a mounted state.

A printed board 14 is attached to the side surface 11 of the housing body 1, which has a hole 12 through which wiring to the outside is inserted, and a plurality of connectors 13 on the inner bottom surface to relay wiring to other units or external devices. .

With the above configuration, all (or most) of the necessary parts are attached and connected to the printed board 4 so that operations can be performed from the front side 32 of the front board 3 and the display can be seen. There is.

Therefore, the mother print pattern connected by the plug-in of the card printed board 6 formed on a part of the printed board 4 and the operation display component etc. are connected by the printed board pattern.

Also, for wiring with other units etc., print 4 and connector 1
3 using a flexible multi-core ribbon cable, etc.

As explained above, the structure of the supervisory control unit of the multiplex wireless device according to the present invention allows the card printed board for the control circuit to be plug-in connected to the inner surface of the front panel which can be opened and closed laterally with a hinge from the main body of the casing as a door structure. By making the front panel a one-piece structure with operation display parts, etc. attached to the main parts facing the front side of the front panel and connected printed boards attached in parallel, the front surface of the front panel has a sufficient area. Because of this, operation display parts and the like can be arranged in the most convenient manner, and with the front panel open, adjustment of the nine internal circuit components, maintenance and inspection can be carried out.

In addition, since the mother printed board of the control circuit card board is integrally formed as a part of the printed board to which the operation display parts are attached, there is no need to use separate wires for wiring. External connections can be made by connecting the printed board at the bottom of the main unit with a ribbon cable, etc.

Furthermore, the above assembly work only needs to be done for the main body of the case and the front panel, and the inside of the main body of the case is especially convenient for work since a large space can be opened inside the front panel with the front panel open. It shows the effectiveness.
