The present invention relates to a plug socket with means of buoyancy. Receptacle made in accordance with the present invention, particularly suitable for easy removal of her plugs.

One of the essential features of known plug sockets is that they fix the fork by coordinating with them on the form. With proper selection of the dimensions of the contact pins of the plug, the force required to extract the plug from the electrical outlet is within 9-54 H, with the specified upper limit is unacceptably high. It is well known that the plug, when it gets stuck in the receptacle can be removed from the receptacle only using both hands. In this case, due to the increase of force required to eject the plug, the socket may be partially or completely torn from the wall, which can lead to electric shock. In order to avoid such a dangerous situation outlet you may need to hold with one hand while your other hand to pull the plug with the required force. The danger of pulling out the plug from the wall outlet may be further reduced when using the mounting ears attached to a hidden part of the receptacle. In order to do the removing plugs from sockets easier, in particular for people with disabilities, and to provide for removing the fork with one hand, the necessary receptacle, which contains additional tools for easier extraction of the plug.

In U.S. patent No. 4042292 described receptacle, removing the plugs of which are carried out with the deviating plate two shoulders of the lever. One arm of this lever is the working arm, while the other shoulder is made in the form of a hinged plate which is used for immediate ejection of the plug. The disadvantage of this solution is that due to structural features hinged plate effective length of the contact pins of the plug must be less than usual, and that the operating handle protrudes from the plane of the wall and thus may be damaged, for example, when moving furniture or it can damage other objects.

In U.S. patent No. 4114969 described receptacle, in which the extraction of the inserted plug helps compressed spring. Although the spring, which is compressed when the plug is completely inserted, facilitates its extraction becomes more difficult to insert the plug into the outlet, as to insert the plug on each side surrounded by a movable body, and, therefore, it is impossible to see what riental contact pins of the plug. Another disadvantage of such sockets is that the spring mechanism significantly increases the dimensions of the plug.

In the patent DE 2128601 described receptacle, provided with the ejection mechanism, which is based on the principle of two shoulders of the lever. In this technical solution, the driving lever and push the shoulder accommodated in the housing receptacle, and drive the shoulder is moved directly by the plunger protruding from the plane of the wall and provided with a pushbutton. The plunger can be moved perpendicular to the plane of the wall. To extract the plugs need to click on the pusher in the direction of the outlet. The disadvantage of this solution is that the plunger protrudes from the front surface of the receptacle, and it is not possible to insert into the slot wider forks, such as the charger for the mobile phone. In addition, the design of this receptacle does not meet the relevant standards.

In the above-mentioned document describes and other structures receptacle embodying the buoyancy, which is based essentially on one shoulder arm. In one of these receptacles inside is only eject the shoulder while driving shoulder ledge of the et from the electrical outlet. To extract the plug on the drive shoulder, equipped with a pressure button should be pressed in the direction from the center of the receptacle parallel to the plane of the wall. In the receptacle of another type driving shoulder, and pushing the shoulder is placed inside the receptacle, and a drive shoulder move with the help of a rope and handle, with the handle, which is connected with a rope, is positioned outside of the receptacle. To extract the plug from the electrical outlet you need to pull the handle. The drawback of such solutions is that moving by stretching out is quite inconvenient and inefficient from the point of view of ergonomics and can lead to tilting of the receptacle in the lateral direction.

In the patent DE 2512193 also described receptacle with means of buoyancy, which is based on the principle of two shoulders of the lever and removing the plug helps a spring-loaded mechanism that is installed in the receptacle. To extract the plug from the electrical outlet you must click on the drive side with a spring mechanism that contains a ratchet mechanism, resulting in a yoke connected with the push shoulder, transmits the force to the contact pins of the plug, pushing them. Although the forces acting on the plug, and the hour of the surface at its contact pins perpendicular to the plane of the wall and thus, stuck a fork in an outlet in the process of its extraction can be avoided, a significant drawback of such receptacles is that the force that must be applied when inserting the plug into the outlet, more than twice the force applied in the case of conventional sockets, which makes it difficult to insert the plug into the socket.

In the patent HU 208882 described receptacle with means of expulsion, including two shoulders lever, eject the shoulder which applies a buoyant force directly to the plug body. Driving shoulder, two shoulders of the lever can be moved by a pusher protruding outward through the cover of the receptacle and capable of moving perpendicular to the plane of the wall. To extract the plug from the receptacle on the plunger having a push button, you must press towards the wall. Since in this solution, the pulling is not involved spring, eliminating the need for application of additional force when inserting the plug into a wall socket. The drawback of such receptacles is that significant forces are concentrated at specific points in the transmission mechanism, which may cause damage to the relevant parts. E is e one disadvantage of this solution is that in the process of pushing the line pushing exposure significantly shifted, resulting in a plug may eventually get stuck in the socket.

In the document FR-A-2740618 described receptacle with means of buoyancy, which includes housing, cover, multiple contact elements and eject the part that is used to eject the plug. In addition, there is a plunger, which is connected with one end of the eject parts. When pressure on the plunger that pushes the workpiece is rotated, causing it extends, pushing the plug. This solution relies on the two shoulders of the lever, one arm of which is the pusher and the other shoulder - eject part.

The aim of the present invention is to eliminate the above mentioned disadvantages inherent in the known plug sockets, and the creation of improved receptacle, which has a simple structure, easy to install and has a low cost of manufacture.

Another objective of the present invention is to create a receptacle in which the line of action of the forces acting on the plug, not offset or no offset in the process of pulling the plug. Another objective of the present invention is to create a more durable with whom edst ejection, what is known, and creating more surface area for transferring efforts than in the known plug sockets.

To achieve these and other purposes are encouraged receptacle with means of expulsion, which includes a housing, a cover housing receptacle, at least one contact element located on the housing receptacle and/or inside at least one eject the item to eject plugs directly or through at least one intermediate part and the plunger connected to one end of the pushing part, and the plunger is held in the housing receptacle and/or the cover can be moved in the direction perpendicular to the plane of the cover, and is used to move the eject details. Eject the item has the sliding surface, mating with the arcuate surface of the housing receptacle, and eject this item is made to move at a specified curved surface for ejection of the plug.

According to the present invention in a preferred embodiment, the receptacle with push item associated timing plunger.

Preferably, the arcuate surface in case the OBD plug is Noah outlet was cylindrical.

Below the socket according to the present invention is described in detail in the examples of the preferred options for its implementation with reference to the accompanying drawings, where:

Figure 2 shows a cross-section of receptacle 11 along the plane a-a before popping the plug 12. In accordance with the fundamental concept of the present invention Vita the bobble-part 13 has an arcuate surface 25 of the slide, such that the pushing part 13 can be moved by the pusher 14 is coupled with the sliding surface arcuate surface of the housing outlet, which is formed inside the housing. The pushing part 13 and the plunger 14 are connected to each other through the agreement form that can be implemented by a toothed plunger 14 and the corresponding gear eject parts 13 or by means of the pressure shoulder, transmitting the force to the end of the pushing part 13. In a preferred embodiment of the present invention, the plunger 14 is in the form of direct and, at least in part, a toothed rod, in particular toothed rack. The plunger 14 is equipped with a push button 19, which is located at its upper end; this push button 19 facilitates pressing on the plunger 14. When plug 12 is inserted in the receptacle 11, the upper surface of the push button 19 and the cover 22 of the receptacle 11 are essentially at the same level.

The pushing part 13 can move along the curved path 15, which preferably is circular. The pushing part 13 consists of two parts, one of which is arcuate and, at least in part, a toothed rack 16, and the other is the end part 17, which is connected with a toothed rack 16. The end part 17 p is remedied along the curved path 15.

When plug 12 is inserted into the outlet 11 and the pushing part 13 is in the initial position, the upper surface of the end portion 17 eject the workpiece 13 is located or in the plane of the inner surface 18 of the receptacle 11, or under it. The lower teeth of the pusher 14 and the lower teeth of the rack 16 are in engagement with each other. The lower end of the plunger 14 includes a housing receptacle 20 in which is formed a guide part 21, which is intended for the direction of the pusher 14. As shown in figure 2, the guide part 21 is preferably a straight line.

Popping plugs 12 perform the following way. When pressing the push button 19, the plunger 14 is moved to the side of the wall. When the plunger 14 applies a tangential force to the arcuate toothed rail 16, causing it to slide along the curved surface 15. Through this move the free end of the end portion 17 extends from the surface 18 of the receptacle 11 in the direction perpendicular to the plane of the wall, and pushes the plug 12.
