DESCRIPTION

Electrical outlet with extractor and platform for type C, E or F plug

The invention relates to a power outlet with or without grounding, fixed with one or two posts or multiple connection posts, movable or adapted with one, two or more connection posts with extractor and type "C" plug platform, type "E" or type "F", according to the international classification of low voltage electrical equipment, each pole has two double-leaf or single-leaf extractors placed face to face.

Several documents are known in the technical field of the present invention, such as document FR 2934721 A1, which describes an electrical outlet comprising a socket for receiving an electrical plug, where the electrical plug connects the socket to a supply network. of energy. The plug has a fuse base that supports two parallel connection pins and a single push-button disconnect unit, which extends to a plug receiving enclosure. Each button can be accessed on the front of the socket, where a transverse movement of the buttons is carried out parallel to the pins. The buttons have a key arranged in a front area located on a right side of the electrical socket so that each push button extends into the socket housing. Each push button comprises, on the back of a key, a body provided with at least one inclined face which, when the push button is pressed, is adapted to support a sliding bearing against a further inclined face provided on the back of the key. movable lower wall of at least one well to move this lower wall from a position of oppression to a position of rise, thus extracting the plug.

Electrical outlets of type "E" or type "F" are known, provided with two extractors for a power plug, each of which has a body provided with a part having a print, actuated by the user with two fingers. of a hand, one of the fingers is the opposable finger, and mounted on a cover, so that one or two anterior triangular lamellae of the same, each with a long active surface, are inclined at an angle of 35... 45°, forming a wedge, they can penetrate through machined slots in a cylindrical wall, which delimit a receiving enclosure, in the latter, to extract the plug from the enclosure, the movement of the extractors results in the advancement, when appropriate , of the slat/slats of each extractor along one or two open channels, machined into a lower wall, which delimits the receiving enclosure, and in which two through holes are also machined, for access to some plug terminals , in the continuation of the long part of the lamella that is located in a flat short lower front part that is permanently located in the open channel, when the plug is introduced into the receiving enclosure, the lamellae moving towards its outer side and blocking the extractors so that they do not come out of the cover through lower lateral prominences, with which they are provided - RO patent no. 121499 B1.

The disadvantages of these sockets described in document FR 2 934 721 A1 and in document RO 121499 B1 are that:

- in case the material of which the body of the plug is composed is flexible, the extraction of the plug from the receiving enclosure requires a relatively high effort, due to the deformation of the contour of the front surface of the plug after its contacts with the active surfaces of the lamellae and, over time, this deformation becomes remanent, also taking place a relative increase in the extraction time;

- the application of a relatively high force is required when initiating the extraction of the plug and when initiating the insertion of the plug from/into the receiving enclosure, respectively, as a consequence of the fact that the active surfaces of the lamellae form, along their entire length , the same angle with the horizontal;

- in the event that the material from which the plug body is made is rigid, such as ceramic or rigid poly(vinyl chloride), an appreciable deterioration of the active surfaces of the lamellae occurs, as a consequence of their contacts with the contour of the bottom surface of the plug.

Type "F" electrical outlets with plug extractor are known, configured in the form of an adapter, which are made of half-shells that, when assembled, form a hollow "T"-shaped shell, being one of the three arms a power plug, and in each of the other two arms, that is, one in the extension of the other, placing, in each case, a main body, provided with a high profile wall that delimits a receiving area, closed in the lower side by a central separating wall, where there are two machined through holes: in front of which are arranged some lamellae of an electrical contact and two diametrically opposed side slots, respectively, and two longitudinal channels are provided in the profiled wall open, along which they can slide to mount and operate, respectively, a platform of an extractor consisting of a thin disc that continues in the contour with two fins that are arranged parallel to each other and on the same side of the disc, each fin is provided with a guide rib, which at a lower end has a short external resilient lamella, placed perpendicular to the rib to permanently maintain the platform in the main body, these guide ribs being placed in the longitudinal channels, between the fins , in the center of the platform an uncompressed spring is mounted, which is placed in a blind hole machined in the central wall, the fins having some long attack surfaces, each inclined at an angle of 30°, on the disc two through holes are provided placed in front of the through holes machined in the central wall, an upper extractor is mounted in front of the platform, consisting of an outer wall, correspondingly profiled for manual operation by a user with a finger, continues with a positioning wall in relation to another positioning wall of another upper extractor, constructively identical to the one mentioned, this positioning wall continues with two narrow fins, arranged parallel to each other, each fin having a guide towards the outer side and an upper wall of the which has a short attack surface with an inclination of 60°, and between the fins, on the upper side, another uncompressed spring is mounted, the upper extractors are mounted in a cutout delimited by another profiled wall, said cutout being machined into the upper half-shell, so that the positioning walls of the narrow fins are in contact, and to extract the plug in contact with the platform disc, the profiled wall of the corresponding extractor is operated manually, by pressure, which has as a consequence the contact between the inclined attack surfaces of the fins and, of the extractor, respectively, and the movement along some rectangular directions of the platform, so that the plug is removed from the electrical contact - Prospect "Fiche multiprise 2P t2 sorties sides with bouchon" Legrand [050637], www.confort - electrique.fr.

The disadvantages of these sockets are that they have a relatively complicated construction and difficult assembly, requiring initial lubrication of the guide paths and the contact surfaces, respectively, which over time, as the lubricant decreases and ages, makes the operation more and more cumbersome, and the overall dimension of the half-shells is relatively high due to the dimensions of the platforms and extractors that perform the plug extraction and keep the platform in the main body, after Possible contact with a hard surface after an accidental fall is uncertain, due to the fragile construction of the short, resilient lamella, imposed by the relatively small available space.

Type "C" electrical outlets with an extractor for a plug are known, which consist of a socket, where some electrical contact lamellas are mounted, and in a cover, respectively, said cover covering both a box that has the socket arranged in it as the socket, the cover being provided with a high cylindrical wall, which delimits, together with a lower wall, a receiving enclosure, two through holes are machined in the lower wall, to insert/remove some plug terminals through the same, as well as a cutout in communication with a window, arranged in a central wall, located on the exterior side of the high wall, which delimits it in part, the cutout being partially delimited on the lower side by a hollow part of the central wall, which has an outer threshold, in front of the part of the high wall that delimits the window, two guides closed to the upper side are provided in the body, through which, in the window, a extractor that in turn has two fins, which penetrate the guides, limiting the upward exit of the extractor, the latter having a lower arm provided with a cutout, into which an inclined outer end of a lever placed, in turn, penetrates. in the cutout, said lever being provided in front of the threshold with a lower projection, around which the displacement of the lever takes place in relation to the hollow part in which, partially, the lever is arranged, which at rest is at the level of the central wall - "AKCENT Gniazdo pojedyncze z wyrzz utnikiem wtyczki, billy", ZUKAJ GP -1AW www.epolmark.pl.

The disadvantages of these sockets are that, over time, residual deformations of the lever occur, which leads to incomplete extraction of the plug and, as a consequence of active contact of the end of the lever with the central area of a plug, made of a flexible material, a deformation of this area occurs which leads to a reduction in the lever travel with undesirable implications after complete extraction of the plug, which has the consequence of increasing the value of the thrust force and the increase in extraction time, under conditions in which the operation of the extractor is uncomfortable due to the upper surface of the body that delimits the window, which has a relatively small dimension for access and placement of the finger used by the user for extraction. operation.

A self-adhesive double thin layer 8 having a contour of the same shape as the shape of the contour j is secured to an upper surface of the body 7. In layer 8, two through holes are machined located in front of holes n, not shown in the figures. The body 7 has on the contour two straight parts p located diametrically opposite, which are convex in cross section and have the shape of an arc of a circle with a radius of 2... 6 mm, in which, in the center, They provide the prominences m. Among the parts p, the contour j has the shape of a spherical sector with the large diameter disposed towards the upper side.

For a plug D of type "E" another independent self-adhesive platform F is used, according to the invention, which has a flat body 9, which follows an external circular contour of the body 4, to which it is attached. In the body 9, two through holes q are machined, located in the center, which have diametrically opposite centers, and a peripheral through hole r arranged so that between the center of the hole r and the centers of the holes q there is an angle of 90 °. On the upper surface s of the body 9, a self-adhesive double thin layer 10 is secured, which has a contour of the same shape as the contour of the body 9. The latter has a contour surface t that has the shape of a spherical sector with a diameter large located in front of the surface s.

The hole r may be crossed by a grounding terminal which subsequently penetrates a recess provided in the body 4, a situation not shown in the figures.

The bodies 7 and 9 are made of a plastic material that is a good dielectric, such as polyamides and, preferably, polypropylene, and have a thickness of 1.5... 3.0 mm.

For a type "C" connector D, not shown in the figures, platform F can be used for its connection, in which case terminals 5 and 6 penetrate through the holes q.

A short flat front part u of the lamella g is permanently located in an open channel v machined in a lower wall w, which delimits a receiving enclosure b.

When attaching a platform E or F to the body 4 of the plug D, the force applied to extract the plug D from the receiving enclosure b or any other receiving enclosure, where a moving part of an extractor is mounted in connection with a socket of current, according to the solutions cited in the known state of the art presented above, in the conditions in which the platform E or F is in contact with the lamellae g or with the moving part, this is 10... 20% more smaller, regardless of the contact surface, than the force applied to extract the socket D to which a platform E or F is not attached.

Under these conditions, there is also a reduction of 8...18% of the total contact break time, compared to the situation in which plug D is used without the existence of platform E or F.

The power outlet according to the invention, in another construction variant, can be type "C" or type "E" or type "F"; The embodiment is presented for a simple type "E" socket, illustrated in Figures 7...17, consisting of a socket A to which a cover G is secured, where a free platform is located and retained H with double lateral guidance, with self-locking.

The cover G consists of a body 11 that has a cylindrical wall In front of each pair of slots in the body 11, two recesses z are provided, each delimited by a profiled lower wall a'. In each recess z a bi-lamellar extractor I is located, said body 12 has a part b' with an external impression and an internal part c', respectively, said part provided with two constructionally identical semi-rigid lamellae arranged in parallel to each other.

Each lamella d' has an active surface e' consisting of two parts f' and g', namely, a lower concave part and an upper concave part, joined together by an intermediate, short and convex part h'. A short lower end i' of part f' is located in an open channel j', machined into a flat lower wall k' that delimits the receiving enclosure y. The parts f' and g' have the shape of an arc of the circle with equal radii, each radius having a value of 10... 15 mm, and the lengths of the chords of the arcs of the circle are unequal, the length of the chord of the part f' is greater than the chord length of part g' by 15... 25%.

In the vicinity of the lower end i' of part f', the tangent to this shape, with a straight line parallel to the lower horizontal edge I' of the lamella d', an angle of attack less than, which has a value of 9 ... 15°, and in the vicinity of the upper end m' of the part g' the tangent to it makes, with a straight line parallel to a vertical edge n' of the lamella d', a higher angle of attack p that It has a value of 17... 23°.

The convex part h' has the shape of an arc of a circle with a radius of 2... 6 mm and has the constructive function of increasing the resistance of the lamella d', in the conditions in which there is a cutout o', located under part h', which ensures displacement over a length of 10... 12 mm of the extractor I, while maintaining the elasticity created in part h', which contributes to relatively reducing the extraction time.

The body 12 is provided, in front of the part b', with two lateral guides p' that penetrate into two channels q' machined in the body 11 in front of the recess z.

In the cylindrical wall short profile mobile t' . The guides s' are located on the outer side of a flat body 13 of the platform H and the guides t' are located on the outer side of a resilient mobile positioning flat part 14. The part 14 has an outer flat part u' and an S-shaped resilient inner part v', respectively, which are placed in a recess w', machined in the body 13 which, to retain the part 14, is provided with two open "T"-shaped guide channels. x', located on each side of the recess w', into which two lateral guides y' of piece 14 penetrate.

The body 13 and the piece 14, which together form a circular contour, are provided with one of some profiled positioning prominences z' and a", placed between the guides s' and between the guides t', respectively, and which, when assembled the platform H in the receiving chamber y, are permanently in contact with the cylindrical wall compressed and the channels r' are closed on the upper side. Within the receiving enclosure y, the platform H is free to move and can be placed on the upper side by means of the extractors I, to keep the enclosure contact with the body 4 of the plug D. In the latter case, to introduce, in a relatively short time, the terminals 5 and 6 through some through holes b" and c", machined in the body 13. on an upper surface d "of the latter, around each of the holes b" and c" there are constructively identical decreasing parts e" and f", whose large diameter is 2...3 times larger than the small diameter that coincides with the diameter of holes b" and c" and which have a depth of 1... 2 mm.

In the body 13, a central through hole g" is also machined for access to a screw that secures the cover G to the socket A, a situation not shown in the figures, and another lateral through hole h", respectively, with a stepped center. at an angle of 90° with respect to the centers of holes b" and c" and located opposite the part 14, through which a grounding terminal 15 can penetrate a recess machined in the body 4, not represented in the figures.

On a lower surface i" of the body 12, between the lamellae d' of the part b', a blind hole j" is machined.

Below the body 11, in front of each extractor I, a thin inner rigid plate 16 is fixed together with a resilient lamella 17, both with the same dimensions. The resilient sheet 17 is provided with a pin k" that is located in front of a through hole I" machined in the plate 16. In the situation in which the platform H is positioned on the upper side, closing the enclosure and, in the hole j" penetrates the pin k" that crosses hole I", keeping it in this position, which allows, in a relatively short time, to introduce the terminals 5 and 6 through the holes b" and c", guided there by means of the parts e" and f".

The body 13 has two zones m" and n" located diametrically opposite, provided with some active contour surfaces o" and p", each of which has, in cross section, the shape of an arc of a circle with a radius of 2. .. 6 mm, which are in contact with the lamellae d'. The body 13 has a thickness of 2... 3 mm.

The locking of each extractor I in the cover G is carried out by the rigid plate 16 that comes into contact with a rear lower shoulder q" of each slat d'.

In this constructive variant, when the platform H is freely mounted in the receiving enclosure y, the extractors I have the slats d' placed in the enclosure y, so that the platform H is located on the upper side of the enclosure y, situation in which the latter is protected against the entry of dust or other foreign bodies. When a plug D made of a plastic material composed of rigid, semi-rigid or flexible poly(vinyl chloride) or ceramic has to be inserted into the enclosure and to achieve electrical contact, by contacting terminals 5 and 6 with the surface d " of the body 13, these are guided in front of the flared parts e" and f", which facilitates the relatively quick introduction of the terminals 5 and 6 into the holes b" and c" and, as a consequence, contact takes place between the plug D and the platform H. By continuing to push the platform H along the channels r', the guides s' and t' move, so that the active outer surfaces o" and p", arranged in the regions m" and n " of the body 13, which are in contact with the slats d', move the latter towards the outer side of the enclosure and, after the stud k" comes out of the blind hole j". By moving the surfaces o" and p' along along the active surfaces e' of the lamellae d', they pass through the upper and lower concave parts g' and f', respectively, which makes the value of the upper angle of attack p guarantee a relatively rapid movement of the extractors I, applying practically the same force until the total displacement of the lamellae d' from the enclosure y.

At the beginning of the extraction of the plug D from the enclosure and, as a result of applying, from the outside, with two fingers of one hand, one of which is the opposable finger, a force on the extractors I, as a consequence of the value of the angle of attack less than, there is a relatively rapid displacement of the lamellas d' towards the inner side of the enclosure and, the value of the pressure force is relatively reduced and maintained at this value until the convex surface h' of the positioned lamellae in front of the cutout o", so that during the contact of the surfaces o" and p" with this surface h' there is an acceleration of the extraction speed of the platform H and implicitly of the plug D.

Due to the relatively small height of the body 11 of the cover G, which has a value of 9...13 mm, the enclosure and is lowered below the level of the body 11, inside the box, to obtain a prescribed depth of the enclosure and with a value of 15 mm, according to international standards. In this situation, to guarantee the travel of the extractors I, as well as to guarantee the necessary elasticity in the front part of the part h', the cutouts o' were provided in the slats d'.

The power outlet according to the invention, in another construction variant, is a double power outlet of type "F", illustrated in Figs. 18... 30 and consists of socket A, to which is secured a cover J on which a free platform K, simply laterally guided, with controlled locking, is placed and retained.

The cover J consists of a body 18 that has a cylindrical wall r" that delimits a receiving enclosure s" and in which four elongated slots are machined, arranged two by two diametrically opposite, a situation not represented in the figures. In front of each pair of slots in the body 18, a recess t", delimited by a profiled lower wall u", is provided. In each recess t" there is located a bi-laminate extractor L whose body 19 has a part v" with an exterior print and an interior part w", respectively, said interior part being provided with two rigid lamellas x" and y", constructionally different from each other and arranged in parallel.

The lamella of part b "85.. .95%. Between the part b " and the horizontal plane there is a lower dihedral angle of attack y, with a value of 18... 22°, and between the part a " and a vertical plane there is an upper dihedral angle 5 with a value of 27 ...35°.

Between the surfaces a " and b " there is a dihedral angle, not positioned in the figures, which has a value of 121... 127°. The lamella y " has an active surface c", which consists of two parts d " and e", namely, a concave upper one and a horizontal flat front short one, respectively, connected to each other. Part e " has a length of 2... 3 mm and is located in an open channel f", machined in a lower wall g " that delimits the receiving enclosure s " Part d " has the shape of a circular arc, with a radius of 25... 35 mm, and the length of the chord of the circular arc is equal to 10... 13 mm.

In the cylindrical wall r" two channels h " are machined open towards the receiving chamber s" and closed on the upper side, where some ends i" and j " of a sliding guide 20 are placed, which is guided in a channel k , which has a "T" shape in cross section according to a transverse plane, said channel being machined in a profiled body 21 of the platform K. The slide 20 has two lateral guides I" that penetrate into the channel k".

The body 21 of the platform K is provided in the center of two recesses m'" located diametrically opposite, and two resilient guides n'", respectively, said guides are arranged diametrically opposite, placed in front of some external guides of the type "plug F" D, in front of some active surfaces of straight contour o", which are convex in cross section and have the shape of an arc of a circle with a radius of 2... 6 mm.

Two through holes p " and q " are machined in the body 21 that can be passed through the terminals 5 and 6, as well as another through hole r " for access to a screw 22 that secures the cover J to the socket A. The slide 20 is positioned in a direction that forms an angle of 45° with the axis joining the centers of the holes p" and q'". The body 21 is provided with two linear profiled edges s'" and t'", which have a height of 1...2 mm, which are arranged in parallel to each other and which enclose the holes p'" and q'", to guide terminals 5 and 6 of plug D inside the latter.

In the vicinity of a lower end u'" of the part d'" the tangent to it forms with a straight line parallel to a lower horizontal edge v"' of the lamella and " a lower angle of attack n that has a value of 9... 15°, and in the vicinity of an upper end w"' of the part d " tangent to it, it forms with a vertical edge x"' of the lamella y" an upper angle of attack 0 with a value of 17 ...23°.

The body 19 has in a part w "a short lateral lower shoulder y"' that locks the extractor L in the cover J, where four short resilient pieces are fixed in a manner known per se, preferably by means of a screw 23. 24. Each piece 24 has a concave part z", which gives it elasticity, as well as a short pin aIV, for positioning inside a lower blind hole bIV machined in the part v" of the extractor L, after having passed through a through hole , machined into the wall u", not positioned in the figures, and a high profiled plug c IV, respectively, which after crossing a through hole d IV provided in the wall u" comes into contact with the shoulder y"'. Each stop (cIV is located in front of a lamella and".

Across the width of the part v", the body 19 is provided with two lower lateral guides eIV, of which the one on the side of the lamella y " is provided with the shoulder y"'. The guides eIV are located in some channels f IV , machined into the body 18.

In this construction variant, the platform K is mounted and retained in the receiving chamber s", located on the upper side, as a consequence of the fact that the slats x" and y" are located entirely in the chamber s", before introducing the plugDin the enclosures", to achieve electrical contact. When the plugD must be inserted into the enclosures", contact of the terminals5 and 6 is initially made with the profiled edgess'" andt™, in order to guide them towards and into the through holesp" andq ".In addition, by pressing the plugD, the platformK moves under the conditions in which the two active surfaceso" of the body21 come into contact with the active surfacesz"yc™ and with the upper partsa™ and dm, respectively, and then with the parts lowerb™ and c™, there taking place a movement towards the outer side of the enclosures "of the lamellae x" and "ey".

In this construction, the height of the body18 of the coverJ guarantees the depth of the receiving enclosure s", which is equal to 18 mm, according to international standards, without placing the wallg™ in the box, which allows a constructive simplification of the slatsx"ey ", since they do not present the constructive recess required in the situation in which the paredg™ would be placed inside the box.

Initially, as a consequence of the existence of the upper angles of attack 5 and 0, with different values, when moving the platform K through the socket D, an unlocking takes place, in a relatively short time, of the extractors L after the bolt a IV comes out of the blind hole b IV. When extracting the plugD of the enclosures", as a consequence of the existence of the lower angles of attack<y>and n, with different values, by means of the manual movement of the extractorsL, the shimsx"ey" move towards the inner side of the enclosures"in a time relatively short and by applying a force with a relatively small value and a variation in time, due to the different geometric shape of the surfacesz"yc™, which means that during extraction their contacts with the surfaceso™ take place alternatively, but diametrically opposite diagonally. As a consequence of the concave shape of the partc™ in front of the intersection of the partsa™ and b™, the movement of the platformLse is carried out without problems, by means of the application, from the outer side, of an extraction force with a relatively constant value, contact taking place only between the parts at m and dm-

The power outlet according to the invention, in another construction variant, can be a single or double power outlet of type "E", a situation in which the embodiment for a double power outlet with ground connection is presented, illustrated in the Figs. 31... 42, which consists of the socket Aa to which a cover M is secured, where two double-leaf extractors N are mounted for each post, one having the function of extracting the plug D, in the situation in which in a receiving enclosure gIV, provided In a body 25 of the cover M, a free platform O is placed, guided by the lower side, held in an upper position.

The enclosuregIV is bordered by some wallshIV and iiIV, namely, a cylindrical lateral one and a flat lower one, respectively. In the wall hIV, four elongated slots, not shown in the figures, are machined for each post, arranged two by two diametrically opposite and in front of each pair of slots of the body 25 there is a recess jIV confined by a lower wall kIV, provided with a threshold interiorlIV below which two supportsmIV and nIV are located, which continue with two long profiled guidesoIV that form an integral part of the wallhIV.

In each recess jIV a bi-foil extractor N is placed whose body26 has two parts pIV and qIV with impression, namely, one external and one internal. The latter has two constructively different rigid lamellae rIV and sIV arranged in parallel to each other, of which lamella IV is constructively identical to lamellay.

The lamellar IV has a long concave activatIV part that has the shape of an arc of a circle with a radius of 18...

24 mm, and the length of the chord of the circle arc is equal to 14... 16 mm.

In the vicinity of a lower enduIV and in the vicinity of an upper endvIV of the parttIV, respectively, the tangents to them form with a straight line parallel to a horizontal edgewIV, and with a vertical edgexIV, some angles of attack<y>y M , namely, a lower one and a higher one, with values of 9... 15° and 17... 23°, respectively.

In front of partpIV, the body26has two lower lateral guidesyIV which, in the vicinity of partqIV, have one of the two shoulderszIV.

On the lower side, in the part pIV of the body26, a marginal blind hole aV is provided located between the shims rIV and sIV, into which a short marginal bolt bV of a long resilient shim penetrates27. The latter also has a short marginal bolt bV, and between the two studs bV is provided a through hole, not shown in the figures, through which a screw passes to fix the shim27 to a short lower support cV of the body25, a situation not positioned in the figures.

When introducing the extractorN into the recessjIV' the guidesyIV come into contact with the guidesoIV, and the shouldersz,IV, come into contact with two lower limitersdV of a piece28 that closes the recessjIV.The piece28 has two long lower side wallseV, which confine a lower front wall profiledfV that comes into contact with the cylindrical wallhIV.

Between the limiters dV, a through hole gV is machined in the wall fV placed in front of the blind hole aV, when the extractor N has the shims rIV and sIV located in the enclosure gIV, a situation in which the stud bV crosses the hole gV and enters the blind hole aV.

The platform Ohas a body29 having an upper flat part hV of circular shape, which continues with two lower long thin hollow guidesiV located diametrically opposite. The part hV has two through holes jV located in the center, machined inside, which can be passed through terminals 5 and 6 of the plug D. Between the holes jV, in the vicinity of an external cutout kV of the part hV, in In the latter, another peripheral through hole lV is also machined, which is crossed by a grounding terminal 30 fixed to the body 1. Through the cutout kV, access is allowed to a screw 31 to fix the body 25 to the body 1.

In the lower wall iV that confines the enclosure gIV, two through holes mV are machined, placed in the center, which are crossed by terminals 5 and 6, as well as two other through holes nV, crossed by the guides iV and which, subsequently, they enter the two long and thick hollow guides oV To retain the iV guides in the V guides, some stops 32 are introduced into the iV guides and fixed thereto.

The wall iV further has a peripheral through hole pV traversed by the grounding terminal 30.

In this constructive variant, socket A makes it possible to provide the iV wall with the oV guides

The flat part hV has two diametrically opposite arranged regions qV, placed in front of the pairs of lamellae rIV and s IV, which have some active curved contour surfaces rV, which are convex in cross section and have the shape of an arc of a circle with a radius of 2... 6 mm.

On the upper side, the hV part has two long profiled edges sV and tV, arranged parallel to each other, with a height of 1... 2 mm, which frame the holes jV that delimit a wide channel uV for guiding the terminals 5 and 6 towards the jV holes.

Four vV channels are machined in the iIV wall, placed in pairs diametrically opposite, along which the rIV and s IV lamellae can move.

In this construction variant, the platform O is mounted and retained in the receiving chamber gIV and is placed on the upper side, as a consequence of the fact that the lamellae rIV and sIV are located entirely in the chamber gIV. When plug D must be inserted into the enclosure gIV to achieve electrical contact, contact is made between terminals 5 and 6 and the profiled edges sV and tV, in order to guide them towards and into the through holes jV. Furthermore, by pushing the plug D, the platform O moves, under the conditions in which the two active surfaces rV of the body 29 come into contact with the active concave part t IV of the lamella rIV and with a part of an active surface of the lamella s IV, respectively, which is identical to the part d'" of an active surface c'" of the lamella y". Initially, due to the values of the upper angles of attack p and 0, which can be equal between yes, between the limits indicated above, there is a relatively rapid movement of the lamellae rIV and s IV towards the external side of the enclosure g IV. Then, the thrust of the plug D and implicitly that of the platform O continues, under the conditions in. which two active surfaces rV come into contact with the part t,IV, and with the part constructively identical to the part d'", respectively, which have radii of different values, which results in obtaining some alternating contacts of the rV surfaces with these, but diametrically. diagonally opposite, which contributes to maintaining the speed of movement of the rIV and sIV lamellae throughout the entire time until the electrical contact ends.

When extracting the plug D from the gIV enclosure, as a consequence of the values of the lower angles of attack A and n that can be equal to each other, between the limits indicated above, by manually moving the extractors N, the lamellae rIV and s IV move towards the inner side of the enclosure gIV in a relatively short time and applying a force with a relatively small value and variation in time, due to the different geometric shapes of the active surface of the lamella s IV and the active surface t IV of the lamella rIV, respectively; During extraction, its contacts with the rV surfaces take place alternately, but diametrically opposite, diagonally, which guarantees a continuous and smooth extraction.

In this construction variant, the height of the body 25 of the cover M ensures a depth of the receiving enclosure gIV, which, according to international standards, has a value of 15 mm, so that socket A allows obtaining the guides oV, located in the lower side of the body 25 of the cover M, where the guides iV of the platform O can move in both directions. The latter is retained inside the enclosure gIV by means of the stops 32.

The power outlet according to the invention, in another construction variant, can be of the single or double "C" type, illustrated in Figs. 43... 51, which consists of socket A, to which a cover P is fixed, in whose body 33 two double-leaf extractors Q are mounted for each post, which have the function of extracting socket D, in the situation in which that in a receiving chamber wV provided in the body 33, a free platform R is placed, guided by the lower side, held in the upper position. On a lower wall xV that delimits the receiving area wV provided in the body 33, a free platform R is located, guided towards the lower side, held in the upper position. In a lower wall xV that delimits the receiving room wV, two through holes yV and zV are machined, located in the center, which can be crossed by terminals 5 and 6 of plug D.

The platform R has a body 34 provided with a flat upper part having a circular shape that continues with two long thin and hollow lower guides bVI, arranged diametrically opposite. In part aVI, two through holes cVI and dVI located in the center, diametrically opposite, are machined, which can be crossed by terminals 5 and 6. The guides bVI enter some hollow guides eVI, open at the ends, of the body 33 retained in the latter by some stops 32.

The part aVI has two lower zones fVI, each provided with a curved contour surface gIV, which is convex in cross section and has the shape of an arc of the circle with a radius of 2... 6 mm.

Each extractor Q consists of a body 35 having two hollow parts hVI and iVI with printing, namely, an outer one and an inner one, the latter having two lamellae jVI and kVI, namely, one rigid and one semi-rigid, arranged parallel to each other. . The lamella jVI has an identical construction to that of the lamella y " of the extractor L, and the lamella kVI has an active surface, which has the same geometry as the active surface e' of the lamella d', composed of two concave parts mVI and nVI, namely, a lower and an upper part, joined together by a short convex part oVI, said parts being constructively identical to the parts f', g' and h' of the lamella d' of the extractor I. In front of the part convex oVI in the kVI lamella a cutout pVI is provided, which gives it elasticity during contact between the oVI part and the platform R. The cutout pVI is open on the lower side and delimited by a wall qVI in the form of a circular arc.

On the xV wall there are four mechanized rVI channels located in pairs diametrically opposite, along which the jVI and kVI lamellae can move.

Each extractor Q is retained in the cover P by a closing piece not shown in the figures, which has an identical construction to that of piece 28, which, by means of lower limiters, blocks some shoulders sVI of the extractor Q, and the positioning of The latter in the cover P is made by means of a lateral pin tVI of a long and resilient piece 36, the construction of which is identical to that of the piece 27, which enters a blind hole uVI of the extractor Q, which surrounds the receiving enclosure wV The Piece 36 is fixed to the cover P in a manner known per se, for example, by means of a screw, which penetrates a through hole, arranged in the center of the piece 36, and another through hole, respectively, said hole being machined in the body 33, finally penetrating the uVI orifice, a situation not represented in the figures. The shoulders sVI are positioned on some long lower guides vVI of the body 35, which in turn are positioned in contact with some supports of the body 33, not represented in the figures, which have the same construction as that of the supports mIV and nIV.

In this construction variant, the platform R is mounted and retained in the receiving chamber wV and is placed on the upper side as a result of the fact that the slats jVI and kVI are located completely in the chamber wV When the plug D is to be inserted into the enclosure wV to achieve electrical contact, initially contact takes place between terminals 5 and 6 and the smooth outer surface of the body 34, in order to introduce it into the through holes cVI and dVI. Then, by pushing the plug D, the platform R moves, under the conditions in which the two active surfaces gVI of the body 34 come into contact with a concave part, not positioned in the figures, of the lamella jVI, constructively identical to the d™ part of the lamella y " and with an upper part nVI of the active surface lVI of the lamella kVI, respectively, and initially takes place due to the values of the angles of attack 0 and p, which can be equal between the limits indicated above, a relatively rapid movement of the lamellae jVI and kVI is continued, outside the enclosurewV, then the thrust of the plug D and that of the platform R, implicitly, is continued under the conditions in which the two active surfaces gVI of the body come into contact with the upper, non-positioned side of the lamella jVI, constructively identical to the part d™ of the lamella y", and with the upper side nV, respectively, of the lamella kVI, which is constructively identical to the part g' of the lamella d', which results in the achievement of alternating contacts of the surfaces gVI with these, but diametrically opposed, diagonally, which contribute to maintaining a relatively constant speed of movement of the lamellae jVI and kVI throughout the period of time until the electrical contact ends.

When extracting the plug D from the enclosure w V, as a consequence of the values of the lower angles of attack n and a that can be equal to each other, between the limits indicated above, when manually moving the extractors Q, the shims jVI and kVI move towards the inner side of the enclosure w V in a relatively short time and by applying a force with a relatively small value and variation in time, taking into account the different geometric shape of the active, non-positioned surface of the lamella jVI, which is constructively identical to the active surface c" of the lamella y", and the active surface lVI of the lamella kVI, which means that, during extraction, its contacts with the surfaces gVI take place alternatively, but diametrically opposite, diagonally, which guarantees continuous and smooth extraction, by applying a force of relatively small value.

In this constructive variant, the height of the body 33 ensures the depth of the receiving enclosure wVI, and the cutout p VI in the lamella kVI ensures only the elasticity in the part oVI of this lamella kVI, which makes possible movement along the lVI guides, in both directions, of the bVI guides.

The holes cVI and dVI machined in the body 34 can be surrounded by two long edges or surrounded by some parts in the form of a truncated cone with a height and depth of 1...2 mm, respectively, situations not represented in the figures.

The power outlet according to the invention, in another construction variant, can preferably be of single or double "F" type, with grounding, a situation in which the embodiment is presented for a simple adaptation power outlet, illustrated in Figs. 52... 54, which consists of a lower half-shell S to which an upper half-shell T is removably attached.

The half-shell S consists of a body 36, where there are two fixed terminals 37 and 38, as well as two grounding plates 39, and which has two prominences wvi arranged diametrically opposite.
