Description

The utility model relates to the design of the plug for the cord of an electrical appliance and can be used to connect several electrical appliances to a single electrical outlet.

To connect the appliance, you must plug the appliance into a power outlet. There is a wide variety of plug and socket designs. For the simultaneous connection of several electrical appliances to the same outlet, the designs of two or three-seater sockets are known. In addition, for simultaneous connection of several plugs to a single outlet, there are splitters or extension cords.

Also known are additional sockets, the so-called adapters or adapters, for example, of the “Start” type, which are designed to coordinate different sizes of plugs and sockets. Such adapters have, on the one hand, contacts that are inserted into a plug of a certain size, and on the other hand, holes into which a plug of a different size can be inserted.

The main drawback of all the above designs is that if all the sockets are already occupied by plugs, then the connection of the new device to the mains is excluded. We have to turn on the devices in turn, which is inconvenient and requires a large number of splitters.

The closest technical solution to the proposed plug design is a power cord with a plug according to the patent of the Russian Federation for utility model No. 2267196, IPC: H01R 31/02, priority from 2004.06.23. The proposed power cord is designed to expand functionality by providing the ability to simultaneously connect multiple appliances to the same outlet.

The specified power cord with a socket contains a housing in which are placed parallel docking modules, each in the form of self-locking

locks from a pair of gear hooks. In the connection planes of the modules, electrical outlets are mounted, sequentially switched between each other by means of the corresponding conductive groups. A power cord of this design allows you to connect several plugs from different electrical appliances to the same outlet, but their number is limited by the number of power cord modules. In addition, the design of the prototype is difficult to manufacture and inconvenient to use.

To eliminate such shortcomings - simplifying the design, expanding the functionality and improving the usability - an improved fork design is proposed.

To solve this problem, the plug for the power cord of the appliance, comprising a housing in which the output contacts are fixed, connected to the wires of the power cord of the appliance, is supplemented with receiving contacts that are coaxial with the output contacts and are configured to interact with the output contacts.

The proposed improvements to the plug of the power cords of electrical appliances allow you to connect several electrical appliances into one outlet without acquiring additional devices in the form of extension cords or splitters. The design of the proposed plug is easy to manufacture and convenient to use.

The proposed plug is illustrated by drawings, which show:

Figure 1 is a General view of the plug for the power cord, front view;

Figure 2 is a General view of the plug for the power cord, rear view;

Figure 3 is a side view

Figure 4 is a section aa of a side view of figure 3;

5 is a variant of connecting several devices to one outlet, where:

A is a socket

B - the first plug connected,

B - the second plug connected,

G is the standard plug of the appliance.

The proposed plug contains a housing 1 (Figs. 1-4), in which, on the one hand, the output contacts 2 are mounted for inclusion in the socket, and on the other hand, the inlets 3 are aligned with the contacts 2. The inlets 3 serve as guides for the plug contacts of the next device and ensure their alignment with the receiving contacts 4 (figure 5). The output contacts 2 are connected to the receiving contacts 4 and the wire 5 of the power cord of the appliance.

To connect the next device (figure 5), its output contacts must be connected to the output contacts of the previous device. For this, the length h2 of the receiving contact and the depth of the guide hole 3 should be equal to the length h1 of the incoming contact. This will ensure the connection and interaction of the outgoing contacts 2 of the first plug with those coming into the hole 3 of this plug, the outgoing contacts 2 of the subsequent plug. In this case, all devices connected to the plug will be connected to the network in parallel. The plug can be made with or without grounding, as well as with a collapsible housing and not collapsible.

To increase the reliability of the contact connection, the plug housing can be equipped with a connecting, locking device, as well as devices that increase the tightness and safety of electrical connections in everyday life.

The presence of devices with plugs of the proposed design provides an extension of the functionality of the plug - it acquires the function of a splitter or extension cord. The presence of electrical appliances with such plugs eliminates the need to purchase new splitters and extension cords for connecting household appliances, and does not clutter up the living space of apartments.

In addition, this allows you to create new designs of splitters and surge protectors that allow you to more efficiently organize the connection of electrical devices to the network, which is very important for office and computer equipment.
