Description

1. The technical field to which the utility model relates.

The utility model relates to the field of testing equipment and is intended for manual switching of signals in debug mode and the operation of laboratory equipment. Switching device (KU) provides connection to the gap of instrumentation and simulation of breaks in low-frequency, low-voltage, low-voltage communication lines during testing of aircraft systems.

2. The level of technology

The well-known "Universal main explosive unit for testing aviation systems" (Patent US 4870347) is a device that consists of an aluminum case with a cover, on the front board of which are installed: many pairs of input and output control sockets, input and output connectors for connecting systems connected to the input and output control sockets, respectively, toggle switches, each connected to the corresponding input and output control sockets, while a template is installed on the front board, with the designations of the input and output control sockets, so as to provide a visual correlation between the designations on the template and the pairs of control sockets. The device also contains input and output wiring harnesses that connect the input and output connectors respectively to the selected system.

The disadvantages of this device (analogue) include:

- lack of protection against involuntary switching of switching toggle switches in operation mode;

- the lack of the possibility of increasing the analyzed system channels (scalability);

- lack of terminals for grounding;

- the presence of a cover on the device’s case and the location of the connection sockets on the front panel, which does not allow experimenting with the cover of the bursting unit closed and requires more space.

3. Disclosure of the essence of the utility model

The technical result of the proposed utility model is to increase electrical safety when working with KU, the reliability of KU and the accuracy of the measurements during the experiment.

Additional results consist in the possibility of combining several switching devices into one, due to which the number of analyzed channels increases, and in the possibility of installing combined control units in a telecommunication cabinet.

The specified technical result is achieved due to the fact that the proposed switching device, consisting of a housing on which are located: input control sockets, switching toggle switches, output control sockets, input and output connectors, is characterized by the fact that the input and output control groups are grouped on the front panel sockets, while the switching toggle switches are grouped and located in the center, on the side panels, respectively, are the input and output connectors, as well as glue we connect to the body CG, while the housing KU top and bottom of the front panel there are the elements of the suspension.

In a preferred embodiment, the device has suspension elements located on the housing of the control unit above and below the front panel.

In another preferred embodiment, the device has holes made in the housing for combining at least two switching devices.

5. Implementation of a utility model

The switching device is made in the form of a block, on the front side of which there are groups of input (1) and output (3) control sockets, switching toggle switches (2), on the sides of the case there are input (5) and output (6) connection sockets, grounding terminals (7), also the housing has suspension elements (4) and a handle (8) for moving the device.

In this case, each input and output control socket is numbered and corresponds to each switching toggle switch.

Each of the connection sockets is appropriately connected by soldered insulated wires with the corresponding control sockets, while the number of the input control socket corresponds to the output control socket, the switching toggle switch, as well as the leg on the connection socket.

To conduct an experiment, the operator must ensure that the control unit is connected to the gap of the investigated communication line. The connection can be carried out using unique harnesses (cables), for this it is necessary to disconnect the harness connector from the equipment under test and, using the input transitional harness, connect the test equipment harness to the input terminal of the KU connection. An output adapter harness must be connected to the output connector of the KU connection, connecting it to the equipment under study.

After connecting the control unit, the operator gets access to the discrete control of the communication channels, as well as the ability to connect to the communication channels of the measuring device (oscilloscope, multimeter, etc.) through the control sockets.

Depending on the position of the toggle switch, the following switching scheme is implemented:

- the right position implements circuit closure;

- the left position implements an open circuit.

Additionally, on the front panel there are inscriptions <Open>, <closed> and the direction of the arrows is indicated.

The switching device is designed in such a way that two or more KU can be combined with screws that are inserted into the holes (9), previously made in the housing. Thus, the combination of several KU does not require disassembly of the housing. In FIG. 4a, 4b, options for combining KU cases with one or two handles are shown, and in FIG. 4c, an embodiment of combining the housings with the possibility of installation in a telecommunication cabinet by installing additional mounting corners (10) is presented.

Thus, the proposed utility model has several advantages (technical results):

- increasing the electrical safety of work and the accuracy of measurements due to the presence of terminals for connecting grounding to the KU case to the common bus of the system under test;

- improving the reliability of the experiment due to the location of the input and output control sockets and switching toggle switches divided into groups, thereby preventing the involuntary switching of KU switching toggle switches;

- the ability to combine several switching devices into one, which increases the number of analyzed channels, while simultaneously working with several systems on the main and backup channels;

- the ability to install two combined control units in a telecommunications cabinet.
