block 1, used to connect the wires of the external network (not shown in the figure), and a connector 2 for connecting the wires 13 that go to the internal equipment, for example, a computer. On the same printed circuit board 3, electronic components 14 can be demaged. The connection of the corresponding contacts of the terminal block and the connector is carried out by printed circuit board mounting. Obviously, this connection could be carried out in another way, for example, by hinged mounting, but the use of a printed circuit board is more technologically advanced. At least part of these connections can pass through the electrical circuits of electronic components. Electronic components can be, for example, amplifiers, optocoupler galvanic isolation or signal conditioners. The printed circuit board 3 is the cover of the hollow metal housing 4, which is an assembly device for fixing the device in the mounting cabinet. The housing 4 has a rectangular bottom 5, the side edges 6 of which are connected to the side walls 8, and one of the end edges 7 is connected to the end wall 9. On both side walls 8 there are mounting protrusions 10, which can be made, for example, in the form of extensions of the side walls 8 outside the housing in the direction opposite to the end wall 9, and bent at an angle of 90 ° to the side walls 8. These protrusions are symmetrical with respect to the housing 4, they have holes 11 for attaching the device to the structures of the mounting cabinet. Terminal block 1, located on the end edge of the board 3, closes the cavity of the housing 4, forming its second end wall. In the end wall 9 there is a hole 12 for the passage of wires from the connector 2, located on the board 3 opposite the hole 12 in the end wall.

The device operates as follows.

The connection device is mounted between two horizontal. Mounting strips on the front panel of the enclosure. The holes 11 are located one above the other, so that the printed circuit board 3 is located in a vertical plane. This makes it possible to blow them with a vertical air flow to remove heat.

The wires going to the connection device from external devices have a relatively large diameter. The wires 13 coming from the connection device to the computing equipment that ensures the operation of the system have a relatively small diameter, they are usually combined into flat cables ending in a detachable part connected to the contacts of connector 2. The wires from external devices are connected to the contacts of terminal block 1 one at a time. The wires 13 pass through the hole 12. The electrical connection of the corresponding contacts of the terminal block 1 and the connector 2 is carried out by printed circuit board 3. The metal housing 4 provides protection against electromagnetic interference, allowing you to expand the use of the device due to the possibility of installing it outside the metal cabinet. Installation on a printed circuit board 3 electronic components 14 allows you to combine switching.
