Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a rack-shaped housing for multiple radio equipment.

The main parts of the transmitter/receiver of a multiplex radio device are multiple transmitters, receivers, and a supervisory control unit that monitors and controls these multiple transmitters and receivers. It is constructed by connecting power supply or signal lines to each unit with electric wires, and further connecting various three-dimensional circuit elements between the transmitter, receiver, and antenna.

By the way, these configurations conventionally have large equipment parts inside the transmitter and receiver, so the number of units that can be accommodated and mounted in a rack of a specified size is at most two or four, and these units are not conductive. Because it is necessary to position the wave tubes with equal line lengths, vertical units are placed vertically at the top and bottom of the rack to connect the electrical system, and the transmitter and receiver units are mounted on frames made of iron on the back. Since it was installed in the rack, the mounting efficiency was not very good in terms of rack space.

Furthermore, the duplexer, antenna duplexer, etc. of the three-dimensional circuit cannot be installed inside the transmitter/receiver equipment, so they must be suspended from the ceiling of the station building above the equipment.

It was installed and attached to etc.

Also, the three-dimensional circuit on the back of the device had to be fixed to the frame using various metal fittings, making assembly difficult.

The electrical wiring that connects each unit is made by bundling the required number of insulated single-core electric wires, binding them with cotton thread, etc., and fixing them along a rack, etc., and connecting them to the main parts with a connector. Assembling time is inefficient because it takes time to assemble the connections and also to check the wiring after assembly.

The present invention solves the above-mentioned problems and has an extremely simple configuration, making it easy to install the three-dimensional circuit and each unit.

Furthermore, the purpose is to provide a rack-shaped case that can cope with the increase or decrease of units and has excellent wiring connectivity. The main pillar has a cross-sectional shape and has a plurality of T-grooves in the longitudinal direction, and the sub-pillar has a cross-sectional frame shape with a plurality of T-grooves and a comb-shaped part formed in the longitudinal direction, and the main pillar and the sub-pillar are The required microwave three-dimensional circuit is placed in the space facing the pillar, and it is possible to install it in various ways.Furthermore, the main pillar and sub-pillar are arranged so that multiple transmitting devices/receiving devices, monitoring control units, etc. can be installed in front of the opening. The feature is that the pillars are placed in a facing relationship.

Hereinafter, embodiments of the housing structure of the multiplex radio device according to the invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing the main parts of the rack and a partially installed state of the three-dimensional circuit, and FIG. 2 is a sectional view taken along the line A-x in FIG. 1.

A main column 3 and a sub-column 4 are arranged to face each other in parallel between a lower substrate 1 and an upper substrate 2 each having a frame shape, and the frame portions of the substrates 1 and 2 are narrowed and connected using screws.

The main pillar 3 has a large L-shaped cross section, and has one side 31 located on the rear surface of the rack and the other side 32 on the side surface, and a plurality of T grooves 33 are formed in each side in the longitudinal direction.

The sub-pillar 4 has a frame-shaped cross section, and a plurality of T-grooves 41 and comb-tooth-shaped portions 42 are formed in the main portion in the longitudinal direction.

The sub-post 4 is located opposite one side 32 of the main post 3, and the main post 3 and the sub-post 4 form an opening B on the front surface of the rack.
It is on S.

The main column 3 and the sub-column 4 are both formed by cutting an extruded aluminum alloy member into a predetermined length.

With the above configuration, the three-dimensional circuit 5 is arranged in the space facing the main column 3 and the sub-column 4, and the main parts are fixed to the T-grooves 33, 41 of the main column 3 and the sub-column 4 using clasps, screws, etc.

In the figure, a circulator 51 and a low-pass filter 52
, a bandpass filter 53, and a waveguide 54 for connection to a transmitter or receiver, which constitutes a duplexer and an antenna duplexer.

On the other hand, the transmitter, receiver, and supervisory control section (none of which are shown), especially the circuit devices and elements inside the transmitter and receiver, are different from those of conventional devices, and those with the same or better functions are ICs, microwaves, etc. I.C.

Since strip lines, filters, etc. are extremely miniaturized, they are constructed as a horizontally long rectangular unit.

Therefore, each of these units is located at the main pillar 3, which is located approximately in the center of the rack.
A monitoring control unit is attached to the front ends 34, 43 of the sub-pillar 4, and a predetermined number of transmitter units and receiver units are attached in parallel above and below the unit for a relay station, respectively. Connected.

The set of transmitter unit and receiver unit can be easily increased or decreased together with the three-dimensional circuit according to requirements, and has space.

Wiring connections to the transmitter unit and receiver unit are made outside the device by equipping the monitoring and control section with a printed circuit board motherboard.
Most of the wiring between units is done using ribbon cables via this motherboard.

Since the ribbon cable can be electrically connected to a predetermined contact of the connector simply by being inserted between the connectors, there is no need to check the wiring.

If this ribbon cable is laid close to the ribbon cable for wiring of other units, there is a risk of mutual induction interference, so by inserting it between the comb-like portions 42 of the sub-pillar 4, the ribbon cable can be guided with the same effect as a shield. It also supports the cable.

As described above, in the case structure according to the present invention, the rack is composed of a large rigid L-shaped main column and sub-pillars made of extruded aluminum alloy, and most of the equipment is arranged in the T-groove formed in these columns. A transmitter/receiver is configured by attaching each element or unit.

Furthermore, it is possible to easily deal with increases and decreases in the number of transmitters and receivers, and the wiring between units can be connected in a short time using ribbon cables and crimp-type connectors.

This ribbon cable can be inserted along the comb-shaped portion of the sub-pillar to prevent cable guidance problems.

In addition, if the splitter configuration of the three-dimensional circuit placed between the opposing main and sub-pillars is special, it is possible to mount multiple rows in the front and back direction between the opposing columns, allowing for a rational arrangement. No special connection waveguide is required.

Since the waveguide section can be fixed using the T-groove of the frame column, it can be fixed at any position without requiring drilling or other processing.

Therefore, it is not affected by errors in the assembly length of the three-dimensional circuit.

Since the pillars that make up the frame are aluminum shapes, they are lightweight and have excellent effects, such as not requiring any machining to form a frame like in the past.

The housing structure according to the present invention includes the shapes of the upper and lower substrates, the main pillar, the sub-pillar,
The dimensional and positional relationships are not limited to those shown in the examples and can be modified in various ways, and the unit can be mounted by adding other related units such as a display unit, power supply unit, element parts, etc., or by adding a transmitter unit, Since the combination excluding the receiver unit is in the case of a terminal station, it goes without saying that such a case is also included in the scope of the claims.
