Description

The utility model relates to the field of electrical engineering, namely to a contact device for detachable connection of an instrument drawer with fixed conductive contact bodies in low-voltage switchgears.

A contact device is known for detachable connection of a movable instrument unit with stationary contact bodies (RU 2256987C2, published July 20, 2005), comprising a housing of insulating material, as well as contact blocks located in the compartments of the housing. Each contact block contains at least one bent contact link, a bent connecting part and a guide part located between both. In the compartments of the housing is a dividing wall with a window for receiving the guide part.

The disadvantage of the analogue is the laborious manufacture of the housing of the contact device, because it is made by casting from a dielectric material, which requires significant material costs for the manufacture of complex casting molds, as well as a large number of component parts that make up the instrument unit.

The technical result of the claimed utility model is to reduce the complexity of manufacturing the housing of the contact device, simplifying the installation and dismantling of the contact device in the complete switchgear.

The specified technical result is achieved in that the contact device for detachable connection of the movable instrument unit with the stationary contact bodies comprises a housing formed of a base, a front panel and stops, while the base is connected to the front panel using stops by fasteners through holes made on bent shelves the base and the front panel, the base being made in the form of a bent U-shaped metal plate with cutouts for making contacts and for cable outlet, but not The middle panel is made of a metal plate with cutouts for installing detachable connectors, the number of which is determined by the number of detachable connectors to be installed.

Thanks to the housing formed from the base, the front panel and the stops, and the connection of the base to the front panel using the stops with fasteners through holes made on the bent shelves of the base and the front panel, the base is made in the form of a bent U-shaped metal plate with cutouts for making contacts and for cable outlet, and the front panel - from a metal plate with cutouts for installing detachable connectors, the number of which is determined by the number of detachable connectors to be installed the technical result is achieved - reducing the complexity of manufacturing the housing of the contact device, simplifying the installation and dismantling of the contact device in the complete switchgear.

The inventive utility model allows the installation of blocks of various sizes, the installation of various types of plug connectors, greatly simplifies the installation of electrical connections inside the contact device and the dismantling of the contact device in a complete switchgear.

The essence of the claimed utility model is illustrated by drawings.

In FIG. 1 and FIG. 2 shows a general view of the device; in FIG. 3 - shows the base; in FIG. 4, in FIG. 5 - shows the front panel of the device.

In the presented figures, the following notation:

1 - housing;

2 - base;

3 - front panel;

4 - emphasis;

5 - fasteners;

6-holes;

7, 8 - bent shelves of the base and front panel, respectively;

9, 10 - cutouts for installing contacts and for cable output;

11 - cutouts for installing detachable connectors.

The contact device for detachable connection of the movable instrument unit with the stationary contact bodies comprises a housing 1 formed of a base 2, a front panel 3 and stops 4. The base 2 is connected to the front panel 3 by means of stops 4 by fasteners 5 through holes 6 made on bent shelves 7 and 8 of the base and front panel. The base 2 is made in the form of a bent U-shaped metal plate with cutouts 9, 10 for making contacts and for cable output. The front panel 3 is made of a metal plate with cutouts 11 for installing detachable connectors, the number of which is determined by the number of installed detachable connectors.

On the front panel 3, cutouts 11 are made for installing various types of plug connectors for power circuits at a rated current of up to 100A, as well as for installing plug connectors for control circuits containing up to 42 contacts.

Assembly procedure: on the base 2, the stops 4 are installed through the holes 6, then the front panel 3 is installed through the holes 8 using the fasteners 5. Next, the case with various detachable connectors installed in it is installed in the low-voltage package device and is mounted in it through holes 5 using fasteners, the existing handle simplifies installation and dismantling of the housing in a low-voltage complete device. Compared with the prototype, the claimed design has a significantly smaller number of composite parts, all parts are made of sheet metal, which reduces the cost of the claimed design compared to the prototype.

Due to the implementation of the housing formed from the base, the front panel and the stops, and the connection of the base to the front panel using the stops with fasteners through holes made on the bent shelves of the base and the front panel, the base is made in the form of a bent U-shaped metal plate with cutouts for installation contacts for cable output, and the front panel - from a metal plate with cutouts for installing detachable connectors, the number of which is determined by the number of detachable In addition, the technical result is achieved - reducing the complexity of manufacturing the housing of the contact device, simplifying installation and dismantling of the contact device in the complete switchgear.
