    TECHNICAL FIELD AND BACKGROUND OF THE INVENTION The present invention relates to an electrical plug comprising a pin base body with at least two from and perpendicular relative to an end face thereof parallel to an interconnecting female device. relative to the pin base body in said coupling direction so that in a coupling state the plug in an ice coupling layer hits and presses against said female means surrounding surfaces to enable expression of the pins from said female means by generating reaction forces.
    In addition to all kinds of plugs for insertion into electrical cradle sockets, the invention also relates to those for connection with other electrical sockets, such as extension cords, cord wires and the like.
    In order to loosen a plug connection in which a named plug is included, an application of a not insignificant traction force of a person to the plug is required. Applying this power is experienced as especially black kir children, elderly people and people with for other reasons, such as disability, reduced strength or responsibility 30 to grasp objects. For this reason, there is an imminent risk that the person in question chooses to pull the electrical cord connected to the plug instead, which may eventually lead to electrical conductors in this cord being exposed or detached from the plug, which in addition to becoming unusable can lead to electrical accidents. Even people of normal strength tend to find it more comfortable to pull on the electrical cord to loosen a plug connection. The problem is particularly overhanging for plugs that are involved in electrical connections that are often set up and loosened, such as plugs for electrical equipment, such as vacuum cleaners, hair dryers and drills.
    In order to solve the above-mentioned problems, electrical plugs of the initially named kind have been developed. Because such a plug is provided with such an element which in the coupling direction is pressed against the surfaces surrounding the female members of a connector to which the electrical plug is to be connected for expression of the pins from these female members, the connection in which the plug is relatively can be loosened without requirement. on the application of any tensile forces to the plug, nor must the person maneuvering the plug be able to even grip it. Such electrical plugs are known, inter alia, from EP 1 071 169 A1 and US 4 045 106. These earlier [(arid plugs) are, however, in some male respects complicated in construction and / or have acquired relatively significant dimensions in relation to a conventional plug in order to be possible. the inventive "expression function".
    SUMMARY OF THE INVENTION The object of the present invention is to provide an electrical plug of an initially defined type, which is improved in at least some respect relatively previously.This object is achieved according to the invention by providing a plug with the features of appended claims 1.
    By arranging a cap-like cap on which a compressive force can be applied to move it relative to the pin base body and thereby move the element in the same direction relative to the pin base body, an ice connection with simple means and little additional space relative to a conventional plug can be achieved. According to an embodiment of the invention, said element is designed movably relative to the pin base body past said face surface in said ice coupling layer to press against surfaces which said female means open into and which said pin is designed to be inserted into in said coupling state of the plug. Such a plug can fulfill its function in terms of the possibility of disconnecting the ice via the application of a compressive force on the cover, regardless of the appearance of the connector, such as the cradle socket with which it is connected, which is not the case with some prior art electrical plugs. elements do not protrude beyond said face surfaces but are intended to act on said female surfaces surrounding surfaces at a different level than the bottom of a recess into which the plug is inserted. This meant that the plug according to the invention can be made compact.
    According to another embodiment of the invention, the plug comprises a sleeve arranged to receive the pin base body and itself received in and surrounded by said cap and displaceable at least partially into and out of the cap when the cap is moved relative to the pin base body in the respective said coupling direction. The combination of a pin base body, a sleeve which accommodates this sleeve and a sleeve which accommodates the sleeve results in a simple design and reliable function of the plug according to the invention.
    According to another embodiment of the invention, the sleeve is designed to have, in the said coupling state of the plug, its pins seen in the said coupling direction in the region of the pin base body where the pins protrude therefrom.
    According to another embodiment of the invention, the sleeve is designed to form the outer boundary of the plug with outer walls designed to cooperate with cradles at a socket when inserting the plug into a socket with the surfaces directly adjacent to the female members submerged in a bottom neck cavity delimited by said socket walls. Due to such a design of the sleeve, the sleeve and the pin base body together will function as a conventional plug inserted in a named socket, and there is no possibility that in the event that the plug according to the invention is inserted incorrectly use only the pin base body alone as a plug.
    According to another embodiment of the invention, the sleeve is designed to form said element. In this way, the ice-pressing function according to the invention is achieved in a simple manner and the sleeve has a double function in that it houses the pin base body and also provides expression of the pins from the female members when applying a compressive force to the cutter in the coupling direction. This design is particularly advantageous in the case of a plug according to the most recently discussed embodiment, in which case the sleeve will hold the plug in the socket and be pressed against the bottom of said bottom neck cavity with duck edges.
    According to another embodiment of the invention, the cutter, seen in said coupling direction, has one of an inner cradle of the defined inner cross-section which completely notches the outer cross-sections of the saval sleeve as the pin base body seen in this direction. As a result, no part of the plug will protrude more than the hood at a transverse direction relative to the coupling direction, so that the plug becomes compact and the risk of involuntarily damaging parts of it during its handling is minimized.
    According to another embodiment of the invention, the transmission device is designed to transmit a movement of the cap relative to the sleeve in the coupling direction to a movement of the pin base body relative to the sleeve in the opposite direction.
    According to a further development of the latter embodiment, the transmission device comprises means of the hood designed to, in the event of a named movement of the hood relative to the sleeve in the coupling direction in front of it, push a first transmission part received in the sleeve designed to cooperate with a pin base body. pin base- body food in the sleeve. Such a design of the transmission device is simple and can be given a reliable function.
    According to another embodiment of the invention, the transmission device comprises at least one rack and a gear cooperating therewith, in a further development thereof the rack is fixedly connected to the pin base body and the gear is rotatably mounted in the sleeve. In a further development thereof, the transmission device comprises a gear rod arranged by said cap to actuate to cooperate with said gear for transmitting a movement of the cap relative to the sleeve to a movement of the pin base body relative to the sleeve and thus relative to the cover.
    According to another embodiment of the invention, the transmission device comprises at least one elongate flexible member, such as a rope, and means, such as wheels, designed to deflect the elongate member. This constitutes an alternative possibility of realizing the transmission device of a plug according to the invention.
    According to another embodiment of the invention, the plug comprises a spring means arranged to act on the cap relative to the pin base body in a direction opposite to said coupling direction and be prestressed in a resting layer, and the spring means is designed to cooperate with the cap so that a named movement of the cap in 25 the coupling direction relative to the pin base body is required to apply a spring force of the spring member overcoming force on the Ica-pan in said coupling direction. This ensures that the plug is not involuntarily transferred in a fully or partially disassembled state and thus safely kept in the coupling state when desired and always returns to an inboard layer of the hood and the pin base body corresponding to the said resting layer as soon as no external compressive force is applied to the hood.
    According to a further development of the latter embodiment, the spring member is arranged to act between the hood and the pin base body.
    In this case, the spring means is advantageously a compression spring designed to be compressed during storage of potential energy when the cap is moved relative to the pin base body in the coupling direction.
    According to another embodiment of the invention, the plug comprises a means designed to weld the cap in a welding position relative to the pin base body as far as movement in the coupling direction is concerned to allow insertion of said pin in said female means by applying a compressive force to the cap in the coupling direction, transferable to a release layer may allow movement of the hood in the coupling direction relative to the pin base body. By arranging such a welding means, coupling and ice-coupling of the pin of the plug relative to the said female means can be achieved easily and safely.
    According to another embodiment of the invention, said element is rod-shaped, and in such a case the transmission device may be designed to transmit a movement of the cap relative to the sleeve in the coupling direction to a movement of the rod-shaped element relative to the sleeve and pin base body in the same direction.
    Additional advantages and advantageous features of the invention will become apparent from the following description.
    BRIEF DESCRIPTION OF THE DRAWINGS The following is an example of an embodiment of the invention with reference to the accompanying drawings, in which: Fig. 1 is a perspective view of an electrical plug according to an embodiment of the invention, Fig. 2 is a sectional view of the plug according to Fig. 1 in a group coupling condition, ie inserted with its pins in electrical contact in an electrical socket, Fig. 3 is a Fig. 2 corresponding view illustrating how the plug is connected from a named socket, and Fig. 4 is a partially cut perspective view illustrating the construction of parts of DETAILED DESCRIPTION OF AN INVENTION OF THE INVENTION Fig. 1 illustrates an electrical plug 1 according to an embodiment of the invention, and its structure and function will now be explained with reference to all Figures 1-4.
    The electrical plug has a pin base body 2 with tv6 from and perpendicular relative to an end face 3 of the pin base body parallel in a coupling direction of the plug projecting pin 4, 5 formed in the corresponding female means, which can sit in an electrical cradle socket, in a sleeve in the spirit of an extension cord or the like, to connect to this connected equipment to electricity via a conductor 6 emanating from the plug.
    The pin base body is received in a sleeve 7, which itself is received in a cap 8 arranged on the opposite side of the pin base body towards the pins relative to this body. The sleeve 7 is shown alone in Fig. 4. The sleeve 7 is arranged slidable partly into and out of the cap when moving the cap 8 relative to the pin base body in the opposite direction for connecting the plug with a female member having a shape, i.e. in the direction of the arrow 9 points in Fig. 2. The sleeve is designed to have, in the said coupling state of the plug, which is shown in Fig. 2, its pin seen in the coupling direction 10 coated in the region of the pin base body where the pins 4, 5 protrude from it. The sleeve 7 is designed to form the outer boundary of the plug with outer cradles 11, designed to cooperate with cradles, has a socket when inserting the plug into a socket with the surfaces 12 which directly adjoin the female members sunk into a bottom neck cavity 13 delimited by the socket cradles.
    The plug further has a transmission device designed to transmit a movement of the cap 8 relative to the sleeve 7 in the coupling direction 9 to a movement of the pin base body 2 relative to the sleeve in the opposite direction. To achieve this, the transmission device comprises a gear rack 14 located at the opposite pins of the pin base body and gears 15 rotatably arranged internally in the sleeve 7 arranged in engagement on each side of the rack 14. The transmission device further comprises a transmission rod 16 connected via a crosspiece 19. The transmission part 16 is shown disconnected from other parts of the plug in Fig. 4.
    A spirit 20 of the transmission part 16 is designed to abut against an inner surface 21 of the spirit coated pins opposite the pins 8 to be pushed on by the cap when displacing the cap in the coupling direction 9 relative to the sleeve. The racks 17, 18 of the transmission part 16 are arranged in engagement with the gears on the opposite side, i.e. externally, against the rack 14 of the pin base body.
    A spring means in the form of a compression spring 22 is arranged to act between said inner surface 21 of the cap 8 and a counter surface 23 of the pin base body in a direction opposite to the coupling direction 9 and to be prestressed in a resting layer (the layer according to Fig. 2) has the plug. The spring member is designed to co-operate with the cap so that for a movement of the cap in the coupling direction 9 relative to the pin base body it is required to apply a spring force of the spring member overcoming force on the cap in the coupling direction.
    The plug further comprises a means 24, of which only one wart cooperating with a recess is shown, designed to load the cover 8 relative to the pin base body in a welding layer, by locking the sleeve relative to the cover, which moves in the coupling direction 9 to allow insertion of the pins 4, 5 in female means of a socket by applying a compressive force to the cap in the coupling direction. The means 24 further comprises stop pins (not shown) which, when rotating the cap 8 relative to the sleeve, laser the cap 8 against movement relative to the pin base body 2. This welding means is transferable to a release layer to allow movement of the cap in the coupling direction relative to the sleeve and thus the pin base body. sat at a transfer of the plug from the team according to Fig. 2 to that according to Fig. 3.
    The function of the plug according to the invention is as follows.
    When the plug is to be slammed into a socket, the welding means 24 is brought into a welding position, so that the rest position which the plug has in Fig. 1 will also be maintained by forces to displace the cap 8 relative to the sleeve applied in the direction of the arrow 9. the parts engaging in the plug are immovable relative to each other, and the plug can be connected to a socket by pushing the pins 4, 5 into the female members of the socket by pressing on the end face 25 of the hood 8. Thereby the layer according to Fig. 2 is obtained.
    If it is now desired to disconnect the plug from the socket, the cap 8 is rotated relative to the sleeve 7 via the socket in a flange 26 intended for this purpose, so that the welding agent 24 is transferred under load. The spring member 22 will still hold the plug in the layer shown in Fig. 2. If a compressive force is now applied to the end face 25 of the hood, as shown by the arrow 27 in Fig. 3, and this compressive force is so strong that it forms to overcome the spring force of the spring member 22, then the hood will be displaced in the direction of arrow 9 relative to the sleeve 7. the transmission part 16 in front of it. The racks 17, 18 of the transmission part 16 will cause the gears 15 of the sleeve to rotate, and these will feed the rack 14 of the pin base body in the direction opposite the arrow 9, so that the pin base body will be pushed food into the sleeve and thereby the sleeve to function as a ice coupling element by pressing against the surfaces surrounding the female means for pushing the pins 4, 5 out of the female means by generating reaction forces, as shown in Fig. 3.
    The invention is of course not limited in any way to the embodiment described above, but a number of possibilities for modifications thereof should be obvious to a person skilled in the art without departing from the scope of the invention as defined in the appended claims.
    For example, it would be possible to design the transmission device differently and to provide it with an elongate flexible member, such as a rope, and means, such as wheels designed to recirculate the elongate member to provide the movement pattern described above between the cap, sleeve and pin base body of the ice. of the plug from an outlet. 11
