Description

The invention relates to electrical engineering, in particular to devices providing a detachable connection of two terminals.

The electrocontact assembly is known, which contains a l-shaped rack mounted on an insulating base and having an opening for introducing a wire at the free end, a contact plate made of an elastic electrically conductive material with a longitudinal hole at the end covering the free end of the rack.

However, the known node is a separate device and contains, in addition to the output, additional elements, for example, a plate, a rack.

A contact current lead is known, consisting of a spring-loaded lemma. installed on an insulating base and having a hole for the wire

The principle of operation of the known devices is based on the use of elastic forces. However, the possibilities of such structures are limited, since for connecting large cross-section wires, great effort is required, which means that the complexity increases and the reliability of the connections decreases.

Closest to the present invention is a contact current lead of a transformer comprising a fixed contact element made in the form of a ring and rigidly connected to the transformer winding.

The disadvantage of this technical solution is also limited scope.

The purpose of the invention is the expansion of technological capabilities due to the large efforts of pressing the device, which increases the reliability of the connection.

WITH

Performing the current lead element directly from the output of the connected element, for example, a transformer winding, reduces the labor intensity of manufacturing. The absence of open current-carrying elements increases the safety of work,

This goal is achieved by the fact that a contact current lead of a transformer, containing a fixed contact element made in the form of a ring and rigidly connected to the transformer winding, is equipped with a clamp made in the form of a U-shaped insulation plate, a fixed contact element made directly from the transformer winding, the ring is located in the plane of the U-shaped clamp so that their longitudinal axes are mutually perpendicular.

Figure 1 shows schematically a contact current lead in the open and closed positions; figure 2 - section aa (turned); Fig. 3 shows an embodiment of the ring.

The contact current lead contains a fixed contact element 1, made in the form of a ring from pin 2 of the transformer 3 winding, clamp 4, made in the form of a U-shaped insulating plate rotatably around axis 5, thumb nut 6 screwed onto bolt 7. B the closed position, the contacting part 8 is installed in the fixed element 1 and pressed by the clamp 4 to the insulating panel or to the housing 9. The retention in a predetermined position is carried out with a wing nut 6.
