RU43428U1 - TRANSITION DEVICE FOR PC - Google Patents

Abstract

The adapter device for a personal computer relates to electronic equipment and is designed to configure and debug the tested modules, as well as to rigidly attach and electrically connect the tested module through the transition device and provide strictly horizontal fixation and free access to all control points of the tested modules. The technical result of the claimed utility model is directed to the implementation of a transition device for a PC providing rigid fixation of the tested module in the IBM PC PC system unit, reliable mounting and electrical connection of the tested module to the system trunk, as well as free access to all control points of the tested modules. The technical result is achieved by the fact that additional connectors are introduced in the adapter: the plug of one connector is for the PC slot, and the socket of the other connector, located on the side of the printed circuit board, is used to connect interface lines or coordinated loads. The printed circuit board is made with the deduced control points of the tested modules, which allow you to track information signals. For rigid horizontal fixation of the adapter with the tested module, guides (slides) were made, having a common mounting point with a bracket, which are made with dielectric insulators.

Description

The adapter device for a personal computer relates to electronic equipment and is designed to configure and debug the tested modules, as well as to rigidly attach and electrically connect the tested module through the transition device and provide strictly horizontal fixation and free access to all control points of the tested modules.

A transition device for testing functional boards is known (author, USSR witness No. 330578, IPC N 05 K 7/02, 1972, Bull. No. 8), in which the panel is made in the form of two plates parallel to one another, with the possibility moving and fixing one of them relative to the other. One of them has connectors for connecting to the radio unit. At the other end of the other plate, connectors are fixed for connection to the functional board with the possibility of rotation with the connected functional board relative to the plate. A cover is mounted on the connectors connected to the function board with the possibility of turning it about an axis fixed in the lower part of the plate and provided with slots for installing the function board.

Known transitional device for monitoring the sliding blocks of radio equipment (author, witness USSR No. 459872, IPC N 05 K 7/02, 1975, bull. No. 5), which is a frame with connectors at the ends. The device is equipped with a locking lock located on the front side of the frame, containing a rotary spring-loaded eccentric cam with a groove on the working surface, which interacts by friction jamming with the locking pin of the block.

Known adapter for testing functional boards (author, witness USSR No. 1711352, IPC N 05 K 7702,1992, Bull. No. 5), selected as a prototype, containing a adapter board with connectors for connecting to a controlled unit, a block with connectors for connecting to the function board installed in the rails. The board and block with connectors are rigidly fixed to the rails.

These devices are designed to be installed directly in the radio equipment during their setup, repair and during the monitoring process, which complicates the commissioning and does not provide a rigid fixation of the connection.

The technical result, which is claimed by the claimed utility model, is to develop a transition device for a personal computer, providing rigid horizontal fixation of the tested module, which interacts with the IBM PC personal computer system, and which provides a reliable electrical connection to the system trunk, as well as providing free access to all control points of the tested modules.

The technical result is achieved by the fact that additional connectors are inserted into the transition device: plug (ХР1) - under the PC slot; socket (XS2) - a connector for connecting interface lines (highways) or coordinated loads, which is located on the side of the printed circuit board. The connector of the tested module (XS1) is functionally divided into two parts: the system (bus matching elements DD1, DD2) and user. To ensure rigid horizontal fixation of the adapter with the tested module, guides are introduced (in the form of a slide), which have a common mounting point with a bracket and are made with dielectric insulators to protect against

the effects of electric current on the test module and the transition device.

The essence of the claimed utility model is illustrated by drawings, where:

Figure 1 - General view of the transition device for the PC in front;

Figure 2 - view of the transition device for the PC on the left;

Figure 3 is a top view of a PC adapter; The PC adapter with a specialized Compact PCI bus connector is designed to configure and debug the test modules made in the Euromechanics 3U construct and is mounted rigidly in the PC case and the test module is connected through the XS1 connector, rigidly fixed and horizontally oriented on rails (slides) . To the test points of the tested modules located on the U-shaped small-sized printed circuit board of the adapter device, test and control devices that monitor the presence of information signals passing through the system and user buses are connected. Further, depending on the type of module under test, either coordinated loads or interface lines (highways) are connected to the XS2 socket. After that, the PC is turned on by means of a plug (XP1) and the software necessary for testing the installed test module is loaded. During testing and debugging, both hardware (circuitry) and software errors are detected, the elimination of which ensures the failure-free operation of the module during operation.

An adapter for a PC is shown in the assembly drawing (Figs. 1-3) and contains a printed circuit board 1 with a plug (XP1) 2 for the IBM PC PC slot, connector (XS1) of the tested module 3 and a socket (XS2) 4 located on the side of the printed circuit board for connecting interface lines (highways) or coordinated loads. To the surface

printed circuit board control points are displayed. The electrical connection between the PC system unit and the tested module is carried out using the plug (XP1) 2 and the connector of the tested module 3.

The bracket 5 is mounted on the printed circuit board using a screw connection 6, 7 and has a common mounting point with guides (slides) 8, for rigidity of horizontal fixation. The guides (slides) 8 are designed to accommodate the tested module on them and are fixed by screw connection 9 on the printed circuit board, with which they are made with dielectric insulators 10, which are secured with a secret screw connection 11.

The manufacture of the transition device for the PC does not require unique materials and special technologies, so it can be repeatedly reproduced in production. As well as the transition device, it greatly simplifies the work of personnel when setting up and debugging the tested modules due to their compatibility with a PC, and contributes to reliable mechanical and electrical contact with free access to all control points of the tested module that track information signals.
