SU847410A1 - Adapter for testing sliding-out radio apparatus unit connected to the rack - Google Patents

Description

one

The invention relates to radio electronics and tronicles and can be used in apparatus for monitoring printed circuit boards during their work as part of a rack (section).

A transition device is known for supporting a printed circuit board with mounting outside the frame while simultaneously providing electrical connections to the circuits in the frame for controlling modes under operating conditions.

However, when controlling the retractable circuit board, the device does not provide operator comfort.

It is also known to have an adapter for controlling the sliding blocks of radio equipment, comprising a frame C with guides, on which there are connectors corresponding to the connectors of the sliding block, and connectors corresponding to the connectors of the rack into which the block is inserted. The said device allows access to the elements of the controlled circuit, while maintaining electrical connections with the stand-up units of the L2J rack.

However, measuring electrical parameters with this device does not allow the operator to manipulate,

To control measuring instruments with control elements while simultaneously holding the test leads of the measuring instruments at the right points of the circuit, which is especially important for operations involving, for example, synchronization of an oscilloscope, generator, etc.

The purpose of the invention is to improve the usability.

This goal is achieved by the fact that an adapter for controlling a sliding block of radio equipment connected to a rack contains a frame with guides on which

15, there are connectors corresponding to the rack connectors, and connectors connected to them, corresponding to the connectors of the sliding block, it is equipped with a hinged arm with a movable bracket and retractable spring-loaded probe holders with probes.

FIG. 1 shows schematically a transitional device, side view; Fig.2 is the same, top view; in FIG. 25 the same, general view.

The device comprises a frame 1 with cedi-2 guides made of a dielectric material, serving to fasten a slide-out unit of radio equipment-a printed circuit board 3.

Frame 1 has lugs 4 and tides 5 for accommodating racks 6 with contacts 7 and 8 and retractable probe holders 9 with probes 10 fitted with dielectric heads 11 and clamping springs 12 hinged on them. Probes 10 are connected to the contacts by means of conductor 13 7, and the frame housing 1 is connected by conductor 14 to contact 8.

Connector 15, mounted on frame 1 and connected to its contacts. 16 with contacts 17 of the printed circuit board 3, is connected by extension cable 18 and connector 19 (Fig. 3) to a rack 20,

Frame 1 using eyelets 4 and the latch 21 is connected with a height-adjustable portable bracket -22, having a latch 23 height. The pins 7 and 8 are connected with the potential and grounded inputs of the measuring device 26 by means of the conductors 24 and 25, respectively.

The printed circuit board 3 installed in frame 1 with its contacts 17 is connected to the contacts 16 of connector 15 and is connected via extension cable 18 and connector 19 to the stand 20 circuitry.

Retractable probe holders 9, hinged on the dielectric pillars 6, allow the probes 10 to be installed at a controlled point of the plate, and the clamping springs

, 12 provide a reliable contact at the point of contact of the probe 10 with the board 3. The portable bracket 22 allows the frame 1 with the board 3 to be installed in the right place relative to the rack 20, and with the help of clips 23 and 21 the frame 1 can be fixed at the required height relative to the floor and oriented in space at the request of the operator.
