Abstract

An electric extension cord comprising a European standard receptacle and a two-pin plug connected by an electric cord, characterized in that the plug is equipped with a grounding contact electrically connected to the grounding contacts of the receptacle of the third core cord, while the plug body and the grounding contact are made in accordance with European standard, and the plug pins are made smaller in comparison with the European standard diameter.

Description

ELECTRICAL EXTENSION-TRANSITION

The utility model relates to electrical engineering and can be used in electrical extension cords and extension cords, used to connect computers, office equipment, household and electrical appliances and machines with a grounding plug of European standard to network sockets.

Known electrical adapters containing the male and female parts, combined in one housing or connected by an electric cord (extension cords), attached to a wall mounted wall outlet. The male part contains the pins that are connected to the plug socket, and the female part contains the holes receiving the pins of the plug of the electrical appliance through the socket body. For example, in international application N 93/14540, MKI H 01 R 27/00, publ. 1993, an electric adapter is described comprising a housing in which a socket with recesses is provided, adapted to insert a two-pin plug according to European standard and / or a two-pin plug according to the American standard and / or a two-pin plug according to the Australian standard. At the other end of the casing there are several pins that protrude selectively from this end to form several configurations, each of the pin configurations being adapted so that it can be inserted to connect to a standard electrical outlet. From US patent N 52363374,

MKI 5: H 01 R 13/00, 25/00, 11/00

MKI N 01 R 11/00, NKI 439-505. PublLEEZ g., an extension cord is known that contains a wire with a plug at one end and rosette blocks connected at regular intervals along the wire, one of which is mounted on the other end of the wire. A German patent is also known N 34 30 667, H 01 R 25/00, publ. 1986, which describes an extension cord with a socket block, in which the holes for the pins of the two-pin plug are located at an angle of 45 degrees to the side of the housing of the socket block.

The closest analogue to the claimed utility model is the extension adapter UZh-ShVVP-VP 2x0.75-5.0-Rr, TU 16.K71.113-90 (see Operation Manual, Cheboksary, Cable passage, 13 , JSC Chuvashkabel Plant, 1994, is attached to the application materials), consisting of a two-pin three- or four-pin outlet with grounding and a cord reinforced with a non-separable double-pole plug. The extension cord allows you to adapt the plugs of foreign-made devices to Russian electric networks.

The design of this extension cord does not implement the grounding function provided for in the European standard. In this regard, this extension cord does not provide grounding devices connected to it, equipped with a plug of the European standard.

The objective of the claimed utility model is the creation of an electrical extension cord adapter with advanced functionality.

EFFECT: grounding by an extension cord-adapter of devices connected to it equipped with a European standard plug, when connecting the extension cord to a European standard power outlet.

This is achieved by the fact that in an electric extension cord adapter containing a European standard socket and a two-pin plug connected by an electric cord, unlike the known one, the plug is equipped with a grounding contact electrically connected to the grounding contacts of the receptacle of the third core cord, while the plug body and the grounding contact made in accordance with the European standard, and the plug pins are made reduced in comparison with the European standard, the diameter.

Signs that distinguish from the closest prototype are:

- equipping the plug with a grounding contact,

-connection of the grounding contact with the grounding contacts of the receptacle of the third core cord,

-Fulfillment of the plug body in accordance with the European standard.

Wi

-performance of a grounding contact in accordance with the European standard,

- the implementation of the plug pins of a reduced diameter compared with the European standard.

The figure shows an electrical extension cord adapter. The extension cord contains a flexible three-core cord 1, one end of which is connected to a plug 2, and to the other end of the socket part 3, containing three sockets 4, made in accordance with European standard. Each of the sockets is equipped with a grounding pin 5. The plug 2 is equipped with a grounding pin 6. The body of the plug 2 and grounding contact b are made in accordance with the European standard. Pin 6 is electrically connected to the grounding contacts of the socket part 5 of the third housing cord 1. The plug 2 is equipped with a pair of pins 8, the diameter of which is reduced compared to the European standard and complies with the Russian standard.

Extension adapter works as follows. To connect the device with the grounding plug of the European (Russian) standard (not shown) to the power outlet of the Russian (European) standard, insert the device plug into one of the sockets of the outlet part 5 of the extension cord, and the plug of the latter, in turn, into the Russian ( European) standard (not shown). At the same time, when connecting a device equipped with a European standard plug to the extension cord adapter, and the extension cord adapter itself
