Description

The technical field to which the utility model relates.

The utility model relates to the field of switching equipment and is intended for switching information signals in debug mode and the operation of laboratory equipment. The switchboard (KSh) provides the connection of equipment when working on complexes of semi-natural modeling and control and measuring equipment during operation, maintenance and repair.

State of the art

The well-known "Telecommunication patch panel" (Patent US 6504726 B1) is a device that consists of one or more than one module, which includes a printed circuit board on both sides of which internal and external connectors are located, while the contact spring of each module is electrically connected to a pin on the panel. A patch panel is used to connect telecommunication devices.

The disadvantages of this device (analogue) include:

- the lack of the ability to switch input and output connectors mounted installation. Change of switching is possible only with the development and manufacture of a new printed circuit board;

- the lack of the ability to replace external connectors without changing the printed circuit board and major modifications to the housing design.

- The used connectors and the circuit board topology are optimized for high-frequency signals such as Ethernet, but this solution is not optimal for switching low-frequency signals with a higher current load.

- there is no possibility of folding, which does not allow you to make changes to the switching circuit in the process and to gain access to internal equipment.

The proposed utility model is a universal means of switching and allows you to implement complex switching schemes for the operation of equipment. The use of printed and wall mounting between external and internal connectors allows you to change the switching scheme with minimal time and financial costs. The housing design has a separate detachable strip, which allows you to change external connectors without changing the entire structure, but only by replacing one part. The mounting of a DIN rail on a support plate is provided, which significantly expands the range of installation products. The hinged mechanism of the case allows you to connect instrumentation without disconnecting the cables / harnesses during operation, as well as providing access to internal equipment. Used switching modules optimized for low-frequency signals based on a printed circuit board.

Utility Model Implementation

The control cabinet contains a housing (1) made of metal and painted with powder paint, which provides resistance to mechanical stress and corrosion protection. On the outside of the control panel, external connection sockets (3) are located on the connector strip (2). The split bar can be made for different connectors, which allows, without changing the basic design, to change the number and type of external connectors. Each connector is labeled (X1, X2 ... Xn).

The housing of the control cabinet is equipped with a folding mechanism (Fig. 2) with a tilt angle equal to 120 °, which is mounted directly in the telecommunication rack (6).

On the inner side of the switchboard there are switching modules (9), an organizer (8), a marker strip (12) and a DIN rail (14) located on the supporting strip (13). On the switching module, terminal blocks (10) and internal connection sockets (11) are located on the printed circuit board and are connected by conductive tracks. There is access to external connectors - internal side (7). The presence of DIN rails in the design expands the functionality of the control panel and allows you to place the device protection, conversion and switching of signals.

This switching device operates as follows. The support strip and hinged brackets, bolted, are attached to the telecommunications rack. The blocks required for testing are connected to external connectors located on the split bar, on the outside of the control panel. Electrical signals necessary for the operation of the test blocks are formed by equipment located inside the rack. The sets of signals are connected to the internal connectors of the control panel. In view of the specifics of the operation of the test blocks, the set of signals, their type, quantity and location are unique. The presence of a switching, tracing, marking system allows you to dial for each test block the desired set of signals with the necessary location. KSH maintains operability regardless of the position of the case - open / closed, because no equipment shutdown is required on the inside or outside. The design of the terminal blocks allows the connection of measuring instruments during operation, maintenance and repair. Thus, the proposed utility model allows you to implement switching of complex wiring diagrams, increases the reliability and convenience of testing on complexes of semi-natural modeling.
