SU289528A1 - CABINET FOR RADIO ELECTRONIC EQUIPMENT - Google Patents

Description

The invention relates to cabinets and chassis units for electronic equipment, primarily for control, protection and alarm systems.

Cabinets of similar purpose are known, comprising racks and pivoting sections with compartments for accommodating units of equipment.

The proposed cabinet is characterized in that the sliding blocks are provided with rotary knobs with a plug at one end and a tooth at the other. This facilitates the movement of the sliding blocks.

FIG. 1 shows the cabinet in general; in fig. 2 - pushed out the second block; in fig. 3-4 handles panels.

The cabinet (see Fig. 1) consists of a fixed supporting frame 1, in which a support 3 is fixed on the rotating hinges 2, and a base 4 with an air duct. Rack 3 can be one or two rows. It consists of cast frames and side skins, interconnected by a standard fastening (screw-nut).

The frame 1 has two side plating 5 and 6 ,. one of which (sheathing 6) is made removable for easy wiring of external and internal cable connections. For the same purpose, the rear trim 7 is also made removable.

Lock 8 is provided to secure the stand in the frame to its side trim. In the transport position, the stand is additionally secured to the frame with bolts at the top and bottom.

A frame with panels is installed inside the frame, on which protection settings, nodes, controls and controls, etc. can be placed. Panels are rotated

around vertical axes and easily removed. At the bottom of the frame is a panel with power connecting plates, closed by a protective casing. In the side frame compartment in one or two

There are connecting boards for connecting external cable chains. If necessary, the interconnecting boards can be placed on the opposite side wall. Interconnect boards

They are also covered with a casing to avoid accidental contact with live parts. Sliding blocks of 9 two sizes are installed in the rack, and folding front 10 and rear panels are installed in the sub-wall walls.

Control panels, alarms and control devices are located on the front flip-down panels. On the rear flap panels there are radio elements. For electrical connection of the vydvilnyh units with the cabinet are used on the rear patch panels.

The electrical connection of the electrical elements of the stand and the frame is made by a flexible torsion braid to avoid damage to the wires.

The chassis of the sliding block (see Fig. 2) consists of two (right and left) frames 11, a front 12 and rear 13 panels fastened to the frames with a standard fastening (screwdriver). The rear panel is fixed when assembling the chassis onto the x-hook catcher 14. In each block of the unit, there are two rotary knobs 15, fixed in the extreme upper position by the latches 16.

To extend the block, the knobs 15 are released from the latches and transferred to the lowest position. In this case, the front tooth of the fork pushes the block out of the compartment for a distance sufficient to disconnect the connectors (see Fig. 3). After contact with the protruding pins 17 of the pillar compartment, the handles are moved to the uppermost position and fixed with latches (see Fig. 4). In doing so, the rear tooth of the handle fork engages with the protruding post stud and the unit will be sent to the post compartment.

External cables are inserted through the opening in the bottom of the base under the duct. For the convenience of laying cables, the air duct is made collapsible.

The cabinet can be installed close to the wall, as it is not necessary to approach it from the side or behind during operation. In the cabinet you can: supply and exhaust, supply and natural ventilation be used.

The cabinet and chassis units can be used in stationary and mobile objects for the placement of radio, electronic and electrical equipment.

Subject invention

Cabinet for electronic equipment containing a rack with compartments for blocks fixed in them and a rotary section with compartments for sliding blocks

devices equipped with handles fixed on their front panels, characterized in that, in order to facilitate the removal of the sliding blocks, the handles sounded rotatable and provided at one end with a fork gripping a pin located on the side of the rotary section compartment and at the other end a tooth inserted into the slot of the latch mounted on the sliding block.
