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.

It is known "Switching device" (RF patent No. 179273), taken as a prototype consisting of a housing, on the front panel of which there are groups of input control sockets, output control sockets and switching toggle switches, and input and output connectors for connecting equipment are located on the side panels, a handle is also attached to the body for transporting the device.

The disadvantages of these devices include:

- limited mobility due to the bulky body;

- the lack of additional protection of the device from damage when stacking devices on top of each other due to the location of the groups of input and output control sockets on the front panel of the switching device.

3. Disclosure of the essence of the utility model

The technical result of the proposed utility model is to increase mobility and reduce the dimensions of the device, and, as a result, reduce the weight of the product, as well as additional protection of the control unit from damage when stacking the devices on top of each other due to the location of the control sockets on the side panels of the case.

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, carrying handle, while the input and output connection sockets are located on the side panel, and the switching toggle switches grouped and located on the front panel of the housing, characterized in that on the side panels of the housing are respectively grouped input and output control sockets.

The device proposed as a utility model is as follows.

5. Implementation of a utility model

The switching device is made in the form of a block, on the front side of which there is a group of switching toggle switches (2), on one side panel there are: a group of input control sockets (1), an input connector (3), and on the other side panel there are: a group of output control sockets output (6), output connector (7). Also, the housing (5) has a handle (4) 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, the inscription "Closed" is applied.

If it is necessary to connect grounding equipment to the housing of the switching device, it is possible to switch to one of the mounting screws located on the top panel of the product.

The switching device is designed in such a way that allows the experiment to be performed in a limited space both in laboratory conditions, for example, on semi-natural modeling complexes, and in real conditions - on board an aircraft, due to the fact that the proposed utility model has reduced dimensions and has increased mobility due to the fact that groups of input and output sockets are located on the side panels of the device, which also leads to a decrease in the weight of the product. It can also be noted that due to just such an arrangement of groups of input and output control sockets, the switching device is additionally protected from damage during transportation and storage of the devices on top of each other.

Claims (1)

A switching device consisting of a housing on which the input control jacks, switching toggle switches, output control jacks, a carry handle are located, while the input and output connectors are located on the side panel, and the switching toggle switches are grouped and located on the front panel of the housing, characterized in that on the side panels of the housing are respectively grouped input and output control sockets.
