Description

The field of technology.

The utility model relates to the field of electrical engineering and is used as terminal clamps when creating ordered systems in switch cabinets.

State of the art.

As a prototype to the claimed technical solution, a distribution block on a DIN rail and a mounting panel was adopted (RF patent No. 195391 for a utility model, IPC H02B1 / 00, 01.24.2020). As in the claimed technical solution, the distribution block contains a housing with a cover. In this case, a contact power section is located in the housing.

The prototype has protruding elements with fastening holes on the rear wall of the case, top and bottom, which allow fixing the distribution block when it is placed on the mounting panel. The front of the case is closed with a transparent front panel.

The technical problem being solved is the need to simplify the assembly and placement of the distribution block on a DIN rail. The protruding elements on the housing do not allow the distribution block to be correctly positioned on DIN rails of different profiles.

Disclosure of the proposed technical solution.

The technical result provided by the claimed technical solution is to improve the convenience of assembling the switchgear unit when it is placed on a mounting panel or DIN rail.

The essence of the claimed technical solution lies in the fact that the distribution unit contains a housing, at least two insulated metal contact busbars with screw terminals and a cover. In this case, the housing contains side walls, a rear insulating plate, and the contact rails are located one above the other with a shift. Differs in that

- on the inner surface of each side wall there are pads for contact rails, the first grooves and second grooves, while the first grooves are made from above and below with respect to each pad for the contact bus, and in the first grooves there are covers of the contact rails, while the retainers are installed inside the second grooves with L-shaped sections protruding outwardly relative to the lower part of the body;

- each casing of the contact bus is made transparent and contains at least two annular slots;

- a U-shaped section and a fixing protrusion are made on the end surface of each side wall, while the U-shaped section contains a through rectangular hole, and a U-shaped cut is made on the side surface of the U-shaped section, while the channels between the protruding L-shaped section latch and the U-shaped section of the side wall, as well as between the U-shaped section and the fixing protrusion are designed to accommodate the bent sections of the DIN rail.

The above essence is a set of essential features of the claimed technical solution, ensuring the achievement of the claimed technical result.

The author of the claimed technical solution made a prototype of this solution, the tests of which confirmed the achievement of the technical result.

Brief description of the drawings.

Figure 1 shows a distribution block on a DIN rail; in fig. 2 - case; in fig. 3 - inner surface of the side wall with a contact bus; in fig. 4 - retainer; in fig. 5 - end surfaces of the side walls; in fig. 6 - rear insulating plate assembled with a side wall; in fig. 7 - casing of the contact bus.

Implementation of the technical solution.

The distribution block (Fig. 1) contains a housing, at least two insulated from each other metal zero contact bars (1) with screw terminals and a cover (2).

The contact rails (1) are staggered one above the other and made of brass.

The housing (Fig. 2) contains side walls (3), a rear insulating plate (4) and casings of contact busbars (5). The structural elements of the body are made of non-combustible PA66 polyamide. On the inner surface of each side wall (3), there are pads for contact tires (6) (Fig. 3), the first grooves (7) and the second grooves (8). The pads for the contact rails (6) are located one above the other with a shift. The first grooves (7) are made from above and below with respect to the platform for the contact bus (6). The busbar covers (5) are installed in the first grooves (7). This design makes it possible to remove the bus (1) with the casing of the contact bus (5) from the housing, which simplifies assembly. Inside the second grooves (8), there are latches (9) with L-shaped sections (10) (Fig. 4) protruding outward relative to the lower part of the body.

On the end surface of each side wall (3), a U-shaped section (11) and a fixing protrusion (12) are made. The U-shaped section (11) contains a through rectangular hole (13). On the side surface of the U-shaped section (11) a U-shaped cutout (14) is made, which is intended for mounting the distribution block with fasteners.

Channels (15) (Fig. 5) between the protruding L-shaped section (10) of the retainer (9) and the U-shaped section (11) of the side wall (3), as well as between the U-shaped section (11) and the fixing protrusion ( 12) are designed to accommodate bent sections of a DIN rail.

Stops (16) are made on the upper and lower surfaces of the U-shaped section (11). The rear insulating plate (4) is made transparent and installed between the stops (16) and the end surfaces of the side walls (3) (Fig. 6).

Each casing of the contact bus (5) (Fig. 7) is made transparent and contains at least two annular slots (17), which are designed to break out the hole for entering the wire from the upper side. The annular slots (17) are located on opposite sides of the casing of the contact bus (5), which increases the ease of installation.

The cover (2) is transparent and is installed on the front of the body. With the help of the cover (2), the contact bus (1) is protected from foreign objects entering the housing and the person is protected from accidental contact with live parts.

The order of use.

The distribution block is installed on a DIN rail or on a panel mounting panel. In this case, the protrusions of the DIN rail profile are installed in the channels (15) of the housing. Remove the cover (2) and fix the wires to the contact bus (1) with socket head screws or a screwdriver. If necessary, break out the annular slots (17) of the housings of the contact busbars (5) and lead the wires from the upper side.

Industrial applicability.

The claimed technical solution can be manufactured at any electrical enterprise and will find wide application in switchboard equipment for connecting neutral conductors.
