Description

Power Supply

The proposed utility model relates to the field of telemechanics, and in particular to the equipment of control panels, used to control industrial and energy facilities, that are remote from the control center at considerable distances, through communication channels.

The power supply is declared in the form of a functionally connected physical shell, which serves to accommodate a set of electronics elements assembled and integrated into a single unit for a given purpose.

Devices of a similar purpose are known (see the prospectus of Siemens, catalog 1995 ST-50 Simatic, power supplies).

The known device is made in a rectangular case containing electronic components, terminal blocks and connectors.

A disadvantage of the known device is the inconvenient form of attachment to the shield frame (a tire with a hat-shaped profile, inserted laterally onto a number of typed blocks included in the shield complex).

Substitution and maintenance. Not quite conveniently located terminal leads and inputs.

The objective of the proposed useful device is to address these disadvantages.

The present problem is solved in the power supply unit, consisting of a plastic case with a base, on which there are located means for fastening it in a common control panel, covers with holes for outputting external

parts of the internal element base, with holes for ventilation, as well as from a circuit board located inside the case with elements of a general circuit solution for the electrical part located on it, in which the rear wall of the base has a continuous longitudinal horizontal recess, and the upper rib bounding this recess is provided with horizontal protrusions, and the lower rib bounding the recess is provided with a latch that can be moved in grooves made in the lower rib, and the latch is provided It is secured by a latch and serves to fix the base on a common shield, while the front cover of the case in the upper left part has a step recess, at the bottom of which there is a terminal block for connecting the load, and the recess itself serves to place the connector tip in it, while on the upper side the covers are located from left to right of the input terminal of the supply voltage, then the fuse and the power switch, the housing cover is provided on the front and sides with vertical rows of rectangular holes for ventilation, in the lower part of the base there is a horizontal row of terminal connections, from left to right a connector for connecting the battery, then a ground clip and output terminals for connecting the load, while the circuit board located in the housing, in addition to the elements that go to the front cover, has a filter, a radiator , microcircuit, transformer, inductor and capacitors.

Further, the claimed utility model will be described in more detail based on the drawings, where:

in FIG. 1 - shows a General view of a utility model in a perspective view in a closed case from the front side;

in FIG. 2 - the same from the back;

in FIG. 3 - shows the lower part of the housing cover (view along A), since it is not visible in FIG. 1;

in FIG. 4 - shows a perspective view of a utility model with the cover removed, showing the layout of the internal elemental filling of the housing;

in FIG. 5 - shows the back of the base of the housing of the utility model, schematically shows the design of the mounting of the housing to a common control panel;

in FIG. 6 - a perspective view of the latch, a front view is shown;

in FIG. 7 is the same, rear view.

The utility model (see Figs. 1, 2, 3) consists of a plastic case 1 with a base 2, on which are located the means of fastening it in a common control panel, a cover 3 with holes for outputting the contact and signal parts of the internal element base. The rear wall of the base 2 (see Fig. 2) has a continuous longitudinal, horizontal recess 4, with its upper rib 5 provided with horizontal protrusions 6, and the lower rib 7, bounding the recess 4 from the bottom, provided with a latch 8 (fully shown in Fig. 4 , as well as 5 and 6), with the ability to move in the grooves 9 made in the lower edge 7. 3

The latch 8 of the lower base 2 is made in the form of a flat, rectangular plate, on the front and sides with recessed stepped protrusions 10, which serve to interact with the grooves 9 of the lower rib 7 of the base 2. In the center, the latch plate 8 has a through window 11 (see Fig. 7), in which there are two shaped spring protrusions 12, protruding inwardly in the right and left parts of the window 11. In the upper part of the window 11 there is a spring locking protrusion 13, and these spring protrusions 12, 13 are designed to interact with the semicircular protrusion of the gap zi lower rib 7 of the base 2.

The latch plate 8 has a hole 14 in the lower part for finger grip of the hand, if necessary, to detach the base 2 from the common busbar frame busbar 15 (see Fig. 5).

The front cover 3 of the housing 1 in the upper left part has a step recess 16, at the bottom of which there is a terminal strip 17 for connecting the load with the indicator 18, and the recess itself serves to accommodate the tip of the connector, not shown in the drawing. On the upper side of the cover 3, left-to-right terminals for supply voltage input 19 are located, then a fuse 20 and a power switch 21. The cover 3 of the housing 1 is provided with vertical rows of rectangular openings 22 for ventilation (see FIG. 1) B from the front and sides the bottom of the base is a horizontal row of terminal connections (see Fig. 3). The terminal row is placed on a separate figure for clarity.

2. Ј I 4

In the series of terminal connections from left to right are located: terminal connector 23 for connecting the battery, ground terminal 24 and output terminals 25 for connecting the load.

At the same time, the printed circuit board 26 located in the housing 1 (see Fig. 4), in addition to the elements facing the front cover 3, has a filter 27, a radiator 28, a transformer 29, a chip 30, and capacitors 31 located upside down.

The proposed power supply is included in the set of devices that form the control panels of industrial and energy facilities, which serve to control facilities that are remote from the control center for significant distances.

In the application for a utility model, only the constructive arrangement of the elements and parts of the power supply unit is claimed and its electrical circuit is not considered.

The utility model is intended for industrial production at the enterprise AOZT Yug-Sistema (Krasnodar).

For the manufacture of the power supply, there are production areas for pressing plastic, manufacturing printed circuit boards, assembly and commissioning workshops, as well as teams of installers and adjusters.

The power supply housing can be made of modern plastics, for example, copolymer, acrylonitrile butadiene styrene (DBS), as well as polyethylene.
