Description

Title of the invention: Front element of a power outlet and power outlet

[0001] The present invention relates generally to power outlets.

[0002] The invention relates more particularly to a front element of a power outlet including: - a side wall and a back wall which define a socket for an electrical plug, the socket rising around a central axis from the back wall towards a front opening, - a trim piece attached to one end of said side wall, opposite said bottom wall, so that one front face of the trim piece borders the front opening of the insertion well, - a piston which closes a section of the insertion well, the piston being movable in the insertion well along said central axis between a standby position in which a front face of the piston extends into the front opening of the insertion well flush with the front face of the trim and an operating position in which it is pushed to the bottom of the insertion well, the piston comprising two openings for the insertion of two pins of the electrical plug, - a T-shaped obturator with a generally cylindrical base centered on said central axis and a head comprising two wings extending perpendicularly on either side of the base, the head being positioned immediately below the piston, the obturator being movable: H rotating around the central axis of the insertion well between a closed position in which it locks the piston in the standby position and in which the wings are positioned over the two openings of the piston to block access to the insertion well, and an open position in which it allows the piston to translate between its standby position and its operating position and in which the wings move away from the two openings of the piston, and, H in translation along the central axis of the insertion well, when placed in the open position, between a high position in which the foot extends mostly into the insertion well and a low position in which the head is placed at the bottom of the insertion well, - disengageable locking means adapted to block the shutter in translation when it is in the closed position and which include two stop surfaces placed on the base of the shutter, opposite the head of the shutter, and - a return spring for the shutter in the closed position.

[0003] The invention also relates to a power outlet comprising such a front element mounted in the front part of a base housing electrical connection elements in a rear part.

[0004] The invention finds a particularly advantageous application in the realization of a power outlet according to the German standard comprising a movable piston which is locked in its high standby position.

[0005] Documents FR2967829 and FR2967830, belonging to the applicants, are known to describe a front element as described in the introduction, which is part of a German standard power outlet. This front element has, in particular, a movable piston in the insertion well between a standby position at the top of the insertion well, flush with the cover plate, and an operating position at the bottom of the insertion well. The piston is held in this upper position by a shutter, which can be disengaged by the prongs of the electrical plug inserted into the insertion well, thus increasing the safety of the power outlet. The front element also includes a return spring to return the piston to the standby position when the electrical plug is removed from the insertion well.

[0006] However, in the arrangements according to documents FR2967829 and FR2967830, the front element presents a functional whole inseparable from the base (housing the connection terminals of the electrical plug) on ​​which it is mounted since the return spring of the shutter is interposed between a bottom wall of a rear part of the base and a part of the shutter.

[0007] However, a need has arisen for modular power outlets, also called modular sockets, in which the part forming the insertion well can be detached from the base. Indeed, various types of cover plates and plungers are currently available, notably in different colors. It is therefore common for users to want to change the cover plate and plunger of a power outlet already connected to the electrical grid, for example, to match a new wall paint color. Detaching the part forming the insertion well from the base is also advantageous for replacing or repairing certain defective components of the insertion well.

[0008] In the field of modular power outlets, a front element with a movable piston is known from document FR2978876, belonging to the applicants. This piston has a shaft integral with the insertion well and houses the return spring. However, this front element is only suitable for manufacturing power outlets according to the Franco-Belgian standard, in which the insertion well has a shallower depth than in the German standard.

[0009] Compared to the aforementioned prior art, the present invention proposes a new front element for a composable power outlet according to the German standard, with a movable piston which locks in a disengageable manner in the high standby position.

[0010] More particularly, according to the invention, a front element of a power outlet is proposed as defined in the introduction: - comprising a barrel of predetermined height, closed at the rear by a bottom and opening at the front into the insertion well, the barrel being integral with the bottom wall of the insertion well and being placed under said bottom wall, centered on the central axis to receive, with minimal play, the entire foot of the obturator when it is in the lowered position, the return spring being interposed between the bottom of the barrel and the obturator, - wherein the locking means comprise two bosses, positioned in correspondence with the stop surfaces, said bosses projecting into the insertion well from the bottom wall, the stop surfaces being adapted to come to rest on said bosses when the obturator is in the closed position, and - wherein the obturator head comprises two recessed housings, each of the recessed housings being shaped to accommodate one of the two bosses when the obturator is in the lowered position so that the head extends against the bottom wall of the insertion well.

[0011] In the front element according to the invention, thanks to the shaft integral with the bottom wall of the insertion well, the shutter and the spring are also integral with the insertion well, in the sense that they are held relative to the insertion well even when the front element is not mounted in the base of a power outlet. The front element thus comprises, independently of the base, all the mechanical elements allowing the piston to move between its standby and operating positions and to lock the piston in the standby position.

[0012] The front element then forms an independent functional unit that is easily removable from the base.

[0013] Furthermore, in the front element according to the invention, the projecting bosses on the bottom wall of the insertion well allow the action of the stop surfaces to be shifted towards the front of the front element. Indeed, thanks to the bosses, the stop surfaces do not rest directly on the bottom wall of the insertion well to prevent the obturator from moving when it is in the closed position.These stop surfaces are thus positioned on the foot of the shutter so that said stop surfaces reach the bottom of the barrel in which the foot of the shutter is engaged when the piston is pushed to the bottom of the insertion well of the front element, taking into account the German standard according to which the depth of the insertion well of the current socket, therefore the piston stroke, has a determined value greater than that of the Franco-Belgian standard for a limited total embedment depth of the current socket.

[0014] The recessed housings of the front element according to the invention finally allow complete penetration of the piston despite the presence of the bosses.

[0015] Other features of the front element according to the invention are as follows: - the recessed housings are provided on a rear face, facing the bottom wall of the insertion well, of each of the wings of the obturator head; - the recessed housings are openings that pass through the said wings of the shutter head; - the recessed housings are closed-bottomed recesses that open only onto the rear faces of the said wings of the shutter head; - the bosses are positioned along the edge of the mouth of the barrel, in a diametrically opposite manner; - the bosses have a height, along the central axis of the insertion well, of between 0.5 mm and 2 mm; - each boss presents a bearing face for the stop surfaces when the obturator is in the closed position, said bearing face extending perpendicularly to the central axis of the insertion well; - each boss has an inclined face which extends from said support face towards a cut made in the bottom wall of the insertion shaft, said inclined face being transverse to the central axis of the insertion shaft; - the foot of the obturator comprises two ribs, each rib having a rear end face forming one of the two stop surfaces, the ribs extending straight along the foot of the obturator from the head of the obturator to the stop surfaces; - the barrel includes two elongated openings forming guide grooves in which said ribs slide when the shutter is translated between its upper and lower positions; - the foot of the shutter forms a hollow cylinder open at one free end turned towards the bottom of the barrel, the hollow cylinder housing said spring, wedged between the bottom of the barrel and the closed bottom of said hollow cylinder; - the shutter is a single piece.

[0016] The invention also proposes a power outlet comprising a base having a rear portion, closed at the rear by a back panel, housing phase and neutral connection terminals, and a front portion, open at the front, in which a front element according to the invention is mounted, the insertion well of the front element having a depth determined according to the German standard, the shaft of the front element being housed in the rear portion of the base, the rear and front portions of the base being separated by an insulating closing panel provided with two openings through which pins of an electrical plug inserted in the insertion well of the front element access said connection terminals, the wings of the shutter of the front element being placed opposite said orifices when the shutter is in the closed position and away from said orifices when the shutter is in the open position, the front opening of the front part of the base being bordered by a sidewalk having a rear face intended to rest on a receiving wall, the base having, between the rear face of said sidewalk and the external face of the bottom wall of the rear part of the base, a depth of embedment determined in accordance with the German standard.

[0017] The following description, in relation to the attached drawings, given by way of non-limiting examples, will make it clear what the invention consists of and how it can be implemented.

[0028] By convention, the terms "front" and "rear" will be used in relation to the The direction of the user's gaze towards the power outlet mounted in a receiving wall. Thus, the front of an element will designate the side of that element which is facing the user, and the back will designate the opposite side.

[0029] The terms "interior or internal" and "exterior or external" shall be used with reference to the socket itself, to designate respectively the side of an element turned towards the center of the socket and the side of an element turned towards the outside of that socket.

[0030] Figures 1 to 4 show a so-called modular 700 power outlet, insofar as it comprises a front element and a rear element that are structurally and functionally independent of each other, assembled or cooperating together. to form a functional whole. Advantageously, in a modular socket, each element must by itself ensure the electrical safety of a user so that the latter can safely access said element and / or manipulate it.

[0031] Here, it is a 700 power outlet conforming to the German standard.

[0032] The power outlet 700 comprises a base 100 belonging to the rear element of the modular plug.

[0033] This base 100 is made of insulating material, for example by molding a plastic material.

[0034] As shown in [Fig. 1], the base 100 has an overall parallelepiped shape. This base 100 is open at the front. It comprises a back wall 101 bordered by a side wall 102 having four faces, two opposite in pair, which rise from the back wall 101, substantially perpendicular to it.

[0035] The base 100 houses a cover 110 (figures 1, 3 and 4), made of insulating material, which forms an intermediate wall dividing the interior space of the base 100 into two parts: a front part 100A and a rear part 100B.

[0036] The hood 110 is here arranged against a shoulder 103 of the side wall 102 located at the boundary between the rear part 100B and the front part 100A of the base 100 ([Fig.3]).

[0037] The rear part 100B is an enclosed space extending between the bottom wall 101 of the base 100 and the hood 110 (figures 3 and 4) while the front part 100A is an open space extending between the hood 110 and a front opening 104 of the base 100.

[0038] As shown in [Fig.1], the hood 110 is formed by a plate whose front face 110A is generally flat and extends substantially parallel to the bottom wall 101 of the base 100.

[0039] The cover 110 includes fastening means, typically snap-on means, designed to cooperate with complementary fastening means of the base 100 to prevent any forward movement of the cover 110. Since the cover 110 also rests on the shoulder 103, any rearward movement of this cover 110 is also blocked.

[0040] The front portion 100A of the base 100 includes means for mounting this base 100 in a support for an electrical switchgear mechanism (not shown). This support typically takes the form of a frame or a housing having a central opening through which the base 100 passes.

[0041] More specifically, the base 100 comprises a walkway 120 running along the edge of the front opening 104 of the base 100, slightly recessed from it, and latching means 121 provided in its side wall 102 (Figures 1 and 2). These latching means 121 are more particularly provided on the outer face of two parallel opposing sections of the side wall 102 of the base 100.

[0042] When the sidewalk 120 rests against a front face of the support, forming a receiving wall for the sidewalk 120, the latching means 121 engage with the rear of the support. The support can then be applied against the wall in which the power outlet 700 is intended to be mounted.

[0043] The base 100 has, between a rear face 120A of the sidewalk 120 and an external face 101A of the bottom wall 101 of the base 100, a setback depth determined in accordance with the German standard. In this case, the setback depth is 32 mm.

[0044] The base 100 houses in its rear part 100B electrical contact elements allowing the electrical plug inserted in the power outlet to be connected to the power supply network.

[0045] These electrical contact elements comprise three connection terminals.

[0046] A phase connection terminal 130 and a neutral connection terminal 131 are provided. These are self-connecting terminals, each comprising a metal strip forming a receiving recess and a connection portion with a connecting tab against which a connecting spring blade is pressed. An electrical conductor from the power supply network carrying the phase or neutral current is intended to be connected to the phase or neutral terminal by being pinched between the connecting spring blade and the connecting tab of the corresponding terminal.

[0047] The receiving recesses of the phase 130 and neutral 131 connection terminals have openings located opposite two circular orifices 111 of the cover 110 which are provided to be passed through by the phase and neutral pins of the corresponding electrical plug when the plug is inserted into the power outlet 700 so that the pins of this plug enter into said receiving recesses.

[0048] An earth terminal electrically connected to an electrical conductor of the network connected to earth is also provided.

[0049] This earthing terminal also includes a connection portion with a connecting tab and a connecting spring blade applied to said connecting tab. It further includes, in this case, a U-shaped metal blade forming a lyre 132, shown in Figures 1 and 4, connected to said connecting tab. The 700 socket shown in Figures 1 to 4 is indeed a 700 socket according to a German standard with lateral earthing contacts. The lyre 132 is conventionally obtained by cutting and bending a metal strip.

[0050] This lyre 132 comprises two lateral arms 132A extending along the inner face of two parallel opposite sides of the lateral wall 102 of the base 100 (these are the sides carrying said snap-on means 121), in the front part 100A of this base 100, and a central arm 132B which connects the lateral arms 132A ([Fig.1]) and which is linked to the connection part. The lateral arms 132A of the 132 yoke have elastic properties. The curved shape of each lateral arm, towards the inside of the 700 power outlet, causes said lateral arms to press against complementary contact areas of the electrical plug when the latter is inserted into the power outlet.

[0051] Openings 140 ([Fig. 1]) are provided in a rear portion of a section of the side wall 102 of the base 100. The bare conductors of the phase, neutral, and earth wires from the power supply are inserted into these openings to be connected to the connection portions of the phase, neutral, and earth terminals. The base 100 also carries three insulating release levers 141 (Figures 1, 3, and 4) which allow the spring-loaded connecting blades of the terminals to be released from the bare conductors.

[0052] Advantageously, to ensure the electrical safety of the rear element of the power outlet 700, a flap 150 is provided housed in the rear part 100B of the base 100, under the cover 110.

[0053] The flap 150 is made in one piece by molding an insulating plastic material.

[0054] This flap 150 is mounted freely in translation between a closing position in which it closes the orifices 111 of the hood 110 and a release position in which it releases the passage through these orifices 111.

[0055] The translational movement of the shutter 150 between its closed position and its open position, which occurs along an axis perpendicular to a central axis A1 of the base 100, is achieved by inserting the pins of the electrical plug inserted into the power outlet 700 through the openings 111 in the cover 110. This translational movement is carried out against an elastic return means that continuously pushes the shutter 150 into its closed position. This elastic return means is a V-shaped spring 160, which is compressed between the shutter 150 and an inner part of the base 100.

[0056] As shown in [Fig.1], the flap 150 has in particular a U-shaped form in which the two arms 152 form sealing panels for the orifices 111 of the hood 110. In the closed position, the two arms 152 are interposed between the orifices 111 of the hood 110 and the phase 130 and neutral 131 connection terminals, as shown in [Fig.3].

[0057] For its movement from its closed position to its open position when the electrical plug is inserted into the power outlet 700, the shutter 150 comprises, at the free end of each of its arms 152, an inclined plane 152A ([Fig.l]). Each inclined plane 152A allows the end of one of the pins of the electrical plug to be supported when it is inserted through one of the holes 111 in the cover 110.

[0058] The inclination of the inclined planes 152A is designed so that when the prongs of the electrical plug are inserted through the openings 111 in the cover 110 and press against these inclined planes 152A, they cause the flap 150 to retract to its release position. This then allows the prongs free access to the receiving recesses of the phase 130 and neutral 131 connection terminals of the power outlet 700.

[0059] As shown in Figures 2 to 4, the front element 710 of the power outlet 700 is mounted from the front in the base 100.

[0060] Advantageously, as already stated, this element before 710 is structurally and functionally independent of the base 100.

[0061] It includes an insertion well 200 for inserting the electrical plug.

[0062] The insertion well 200 is housed in the front part 100A of the base 100 (see figures 3 and 4).

[0063] As Figures 4 and 5 show in particular, the insertion well 200 is more specifically delimited by a bottom wall 201 and a side wall 202. The side wall 202 of the insertion well 200, here generally cylindrical in revolution, is centered around the central axis AL. The insertion well 200 is open at the front and closed at the rear by the bottom wall 201. The central axis Al corresponds to an insertion axis of the electrical plug in the insertion well 200. The bottom wall 201 and side wall 202 of the insertion well 200 belong to a single piece made of an insulating material.

[0064] The insertion well 200 here has a depth determined in accordance with the German standard.

[0065] As shown in [Fig.3], the bottom wall 201 of the insertion well 200 has two openings 210 for the passage of the pins of the electrical plug to the phase 130 and neutral 131 connection terminals. These two openings 210 are positioned in correspondence with the two orifices 111 of the cover 110. The pins of the electrical plug which pass through the openings 210 of the bottom wall 201 of the insertion well 200 are then inserted through the orifices 111 of the cover 110 which give access to the receiving recesses of the phase 130 and neutral 131 connection terminals.

[0066] As shown in [Fig.5], the bottom wall 201 of the insertion well 200 has in its peripheral edge two peripheral cutouts 211 for the passage of the two lateral arms 132A of the lyre 132. The bottom wall 201 of the insertion well 200 is arranged against the hood 110 separating the front 100A and rear 100B parts of the base 100 ([Fig.3]).

[0067] The inner face 202A of the side wall 202 of the insertion well 200 here also has two diametrically opposed rectangular grooves 203 (figures 4 and 7) through which the lateral branches 132A of the lyre 132 protrude inside the insertion well 200.

[0068] The side wall 202 of the insertion well 200 also includes mounting means in the base 100. These mounting means here include two teeth 204 ([Fig.l]) projecting from the external face 202B side wall 202 of the insertion well 200, arranged oppositely with respect to the central axis Al and adapted to hook onto corresponding hooking areas provided in the side wall 102 of the base 100.

[0069] The front element 710 also includes a trim piece 220 attached to a front end 202C of the side wall 202 of the insertion well (figures 4 and 8), opposite the bottom wall 201 of the insertion well 200.

[0070] The trim piece 220 is in the form of a plate 221 with a flat front face 221A and a flat rear face 221B. The plate 221 has a circular opening in its center, centered on the central axis AL. The plate 221 has a square outer contour, but it could also have a circular or rectangular outer contour.

[0071] The central opening of the plate 221 is bordered by a cylindrical inner wall 222 which extends towards the rear of the plate 221, over a low height along the central axis AL. The outer contour of the plate 221 is bordered by a peripheral outer wall 223 which also extends towards the rear of the plate 221, over a low height along the central axis Al, opposite the cylindrical inner wall 222. The cylindrical inner wall 222, the peripheral outer wall 223 and the rear face 221B of the plate 221 define a groove 226 which opens towards the rear of the plate 221.

[0072] As shown in [Fig.1], the plate 221 further carries four mounting tabs 225 which extend from the rear face 221B of the plate 221, towards the rear perpendicular to it. These mounting tabs 225 are positioned at the four cardinal points around the cylindrical inner wall 222. They extend rearward from the free edge 222C of the cylindrical inner wall 222. Each mounting tab 225 has at its free end, on its inner face facing the center of the central opening of the plate 221, a tooth 225A for attaching the trim piece 220 to the side wall 202 of the insertion well 200. The mounting tabs 225 of the trim piece 220 are adapted to be engaged between the outer face 202B and flanges 206 of the side wall 202 of the insertion well 200 so as to hook the teeth 225A onto protruding edges 206A of the outer face 202B of said side wall 202.The aforementioned mounting brackets 225 are held in place, attached to the . side wall 202 of the insertion well 200, thanks to the flanges 206 which press them against said side wall 202.

[0073] When the trim ring 220 is attached to the side wall 202 of the insertion well 200, the central opening of the trim ring 220 forms the front opening 200A of the insertion well of the front element 710 and therefore of the power outlet 700 and the front face 221A of the trim ring 220 forms the front face of the front element 710 of the power outlet 700.

[0074] Finally, when the front element 710 is mounted in the base 100, the rear groove 226 of the trim 220 accommodates a front edge 102A of the side wall 102 of the base 100 and the free edge of the peripheral outer wall 223 of the trim 220 rests on the front face of the sidewalk 120 of the base 100 (see figures 2 and 3).

[0075] Alternatively, the trim and the side wall of the insertion well can be formed from a single piece.

[0076] The front element 710 of the power outlet 700 further includes a piston 300 which closes, i.e., seals, a section of the insertion well 200. This piston 300 is movable in translation in the insertion well 200, along the central axis AL. Here, "closing a section of the insertion well" means that, regardless of its position in the insertion well 200, the piston 300 extends across the insertion well 200, in contact with the side wall 202 and parallel to the bottom wall 201 of the insertion well 200.

[0077] As shown in [Fig. 1], this piston 300 has a main wall 301 with a generally circular contour. The contour of the main wall 301 of the piston 300 has two diametrically opposed cutouts 303 for the passage of the lateral arms 132A of the lyre 132. The front face 301A of the main wall extends here in a plane perpendicular to the central axis AL

[0078] The main wall 301 is partially surrounded by a drop wall 302 oriented towards the rear of the power outlet 700 (figures 1, 5 and 7). This drop wall 302 bears against the inner face 202A of the side wall 202 of the insertion well 200 and guides the sliding of the piston 300 along this side wall 202. The drop wall 302 has four projecting claws 306, evenly spaced around the drop wall 302, adapted to retain the piston 300 in the insertion well 200. These claws 306 have retaining surfaces adapted to lock against the free rear edge 222C of the cylindrical inner wall 222 of the trim piece 220 when the piston 300 reaches the end of its stroke in the upper position in the insertion well 200 (see [Fig. 4]). These claws 306 thus prevent any further forward movement of the piston 300 when they are in contact with the trim piece 220.The side wall 202 of the insertion well 200 has grooves 205 adapted for the passage of the claws 306 when the piston 300 is translated (see figures 4, 5 and 7).

[0079] As shown in [Fig. 1], the piston 300 also includes two pairs of diametrically opposed lugs 305 extending along the central axis Al, from the peripheral edge of the main wall 301 of the piston 300 to the bottom wall 201 of the insertion well 200. These pairs of lugs 305 are designed to slide in translation in guide grooves of lateral uprights 400 (Figures 1, 4 and 7) carried by the inner face 202A of the lateral wall 202 of the insertion well 200. The lateral uprights 400 have an elongated U-shape, the two arms 410 of the U defining a guide groove for the lugs 305 of the piston 300, which prevents the main wall 301 of the piston 300 from tilting relative to the central axis Al.

[0080] The main wall 301 of the piston 300 also has two circular openings 304 (figures 1 to 5, 7 and 8) whose dimensions and positions are adapted to the passage of the pins of the electrical plug inserted in the insertion well 202 of the power outlet 700.

[0081] The piston 300 is more particularly mobile only in translation along the central axis Al of the insertion well 200 between two extreme positions.

[0082] In one of these extreme positions, shown in Figures 4 and 8, hereafter referred to as the operating position, the piston 300 extends as far as possible from the front opening 200A of the insertion well 220. In other words, in the operating position, the piston 300 is completely pushed to the bottom of the insertion well 200.

[0083] In the other extreme position, shown in Figures 2, 3 and 5, hereafter referred to as the waiting position, the piston 300 extends into the front opening 200A of the insertion well 200. In other words, the piston 300 is completely raised to the top of the insertion well 200.

[0084] More specifically, in the waiting position, the front face 301A of the main wall 301 of the piston 300 extends flush with the front face 221A of the plate 221 of the trim 220, as shown in Figures 2, 3 and 5. In other words, in its waiting position, the front face 301A of the main wall 301 of the piston 300 then extends in the same plane as the front face 221A of the plate 221 of the trim 220, or with an offset of less than one tenth of a millimeter.

[0085] In this standby position, the piston 300 closes the entire insertion well 200 and thus limits access to the connection terminals 130, 131, 132.

[0086] Regardless of the position of the piston 300, the openings 304 of the piston 300 are constantly positioned to the right, i.e. aligned along an axis parallel to the central axis Al, of the openings 210 of the bottom wall 201 of the insertion well 200 and of the orifices 111 of the cover 110. This alignment allows the pins of the electrical plug inserted in the insertion well 200 to access, through the openings 304 of the piston 300, the receiving recesses of the phase 130 and neutral 131 connection terminals.

[0087] The piston 300 operates in cooperation with a shutter 500 which belongs to the front element 710.

[0088] As shown in [Fig. 1], the shutter 500 has a T-shaped form with a tubular foot 510 whose axis coincides with the central axis Al, surmounted by a substantially flat plate extending in a plane orthogonal to this central axis Al and forming a head 520 of the shutter 500. As shown in [Fig. 5], the foot 510 of the shutter 500 is generally a hollow cylinder having a free rear end 510A opposite the head 520, which closes the other end. In particular, it has a cylindrical wall 513 extending around the central axis Al.

[0089] The shutter 500 more particularly comprises two wings 521, 522 formed by the two ends of its head 520. The two wings 521, 522 extend on either side of the foot 510 (see [Fig.5]).

[0090] The head 520 of the obturator 500 is positioned immediately below the piston 300 (Figures 3, 4, 5, 7 and 8). As will be described later, the head 520 of the obturator 500 is positioned immediately below the piston 300 regardless of the position of the piston 300 since it is held against the piston 300 by a return spring 650.

[0091] The shutter 500 is movable following two combined movements.

[0092] The shutter 500 is firstly movable in rotation around the central axis Al between a closed position and an open position.

[0093] In the closed position (figures 2, 3 and 5), the obturator 500 allows the openings 304 of the piston 300 to be closed from the rear.

[0094] Indeed, the wings 521, 522 are arranged relative to each other in such a way that, in the closed position, they are positioned directly above the two openings 304 of the piston 300 to block access to the insertion well 200 (Figures 3 and 5). The wings 521, 522 are then aligned respectively with the openings 304 of the piston 300 and the orifices 111 of the cover 110 ([Fig. 3]). Thus, by being interposed between the openings 304 of the piston 300 and the orifices 111 of the cover 110, they prevent access to the phase 130 and neutral 131 connection terminals.

[0095] Conversely, in the open position (figures 4, 7 and 8), the shutter 500 allows access to the phase 130 and neutral 131 connection terminals. To allow access to these terminals 130, 131, the shutter 500 pivots around the central axis Al until its wings 521, 522 move away from the two openings 304 of the piston 300 to free the passage to the orifices 111 of the hood 110 and the mouths of the receiving recesses of the phase 130 and neutral 131 connection terminals.

[0096] As clearly shown in [Fig. 3], for its rotational drive from its closed position to its open position when the electrical plug is engaged in the current socket 700, the shutter 500 has on its two wings 521, 522 two inclined faces 523, 524.

[0097] These two inclined faces 523, 524 are located on the wings 552, 553 in such a way that they are positioned opposite the openings 304 of the piston 300, immediately below these openings 304, when the obturator 500 is in the closed position.

[0098] The two inclined faces 523, 524 are arranged on either side of the central axis Al and each opens onto one of the longitudinal edges 520B of the head 520 of the shutter 500. The inclination of these inclined faces 523, 524 is provided such that, when the pins of the electrical plug are engaged through the openings 304 of the piston 300 and press on these inclined faces 523, 524, they cause the shutter 500 to rotate towards its open position, which allows these pins to freely access the insertion well 200.

[0099] When in the open position, the shutter 500 is also mobile in translation, along the central axis Al, between a high position (see [Fig.3]), in which its foot 510 extends mostly in the insertion well 200, and a low position (see [Fig.4]), in which the head 520 is placed at the bottom of the insertion well 200. By "mostly" means that more than 80% of the length of the foot 510 (along the central axis Al) then extends in the insertion well 200.

[0100] This translational mobility of the obturator 500 allows it to follow the stroke of the piston 300 between its extreme waiting and operating positions.

[0101] The upper position of the obturator 500 corresponds to the waiting position of the piston 300, the piston 300 then extending flush with the front face 221A of the trim 220.

[0102] The lower position of the obturator 500 corresponds to the operating position of the piston 300, the piston 300 being then completely pushed to the bottom of the insertion well 200. Thus, in the lower position, the head 520 of the obturator 500 is in contact with the bottom wall 201 of the insertion well 200.

[0103] The passage of the obturator 500 from its upper position to its lower position is caused by the insertion of the electrical plug into the insertion well 200 which pushes the piston 300 from its waiting position to its operating position at the bottom of the insertion well 200.

[0104] The raising of the shutter 500 from its lower position to its upper position, which also raises the piston 300 to its standby position, is ensured by the return spring 650. This raising occurs automatically when the electrical plug is extracted from the insertion well 200. The return spring 650 is engaged inside the tubular foot 510 of the shutter 500. It is partially engaged in the foot 510 when the shutter 500 is in the upper position ([Fig.5]) and fully engaged in the foot 510 when the shutter 500 is in the lower position ([Fig.8]).

[0105] Remarkably, the front element 710 includes a barrel 600 integral with the bottom wall 201 of the insertion well 200. When the piston 300 is pushed down, and therefore when the obturator 500 moves from its upper position to its lower position, the foot 510 of the obturator 500 engages in the barrel 600.

[0106] As shown in [Fig. 7], the barrel 600 is closed at the rear by a bottom 610 and opens at the front by means of an opening 600A into the insertion well 200. To receive the foot 510 of the shutter 500, the barrel 600 is positioned under the bottom wall 201 of the insertion well 200 and is centered on the central axis A1. The barrel 600 is generally tubular. It has an inner diameter equal, within clearance, to the outer diameter of the cylindrical wall 513 of the foot 510 of the shutter 500 so that said foot 510 fits, within clearance, into the barrel 600 when the shutter 500 moves into the lowered position.

[0107] The bottom 610 of the barrel 600 has two end openings 611 (Figures 5 and 7) for the passage of the rear free end 510A of the foot 510 of the shutter 500, which here has two diametrically opposed extensions that slightly protrude from the bottom 610, towards the rear, when the shutter 500 is in the lowered position, as shown in [Fig. 8]. Here, these two end openings 611 also extend onto the side wall 630 of the barrel 600 along the central axis AL. The bottom wall 101 of the base 100 also has two openings (not shown) corresponding to the end openings 611 of the bottom 610 of the barrel 600.

[0108] The barrel 600 has a height, that is to say a length measured along the central axis Al between the bottom wall 201 of the insertion well 200 and its bottom 610, which allows it to receive, with minimal clearance, the entire foot 510 of the obturator 500 when it is in the lower position, that is to say the entire foot 510 except for the rear free end 510A of the foot 510 protruding from the barrel 600. By receiving the entire foot 510 of the obturator "with minimal clearance" means that 90% of the length of the foot is housed in the barrel 600 in the lower position.

[0109] When the front element 710 is mounted in the base 100, the shaft 600 extends into the rear part 100B of the base 100 (Figures 3 and 4), its height must therefore also be compatible with that of the rear part 100B of the base 100. Once inserted into the rear part 100B of the base 100, the bottom 610 of the shaft 600 is in contact with the bottom wall 101 of the base 100. The shaft 600 passes through the cover 110, which has a central recess 112 ([Fig. 1]) for the passage of the shaft 600 during the assembly of the power socket 700.

[0110] Thanks to the barrel 600, the obturator 500 is guided in rotation and translation relative to the insertion well 200 along the central axis AL

[0111] Indeed, it allows on the one hand to guide the shutter 500 in rotation around the central axis Al since, as shown in [Fig.6], the rear free end 510A of the foot 510 is engaged in the barrel 600 even when the shutter 500 is in the high position. As shown in [Fig.9], in a complementary manner, the obturator 500 is also guided in rotation by an element 307 projecting from the rear face 301B of the main wall 301 of the piston 300 which is engaged in a central recess 525 of the head 520 of the obturator 500.

[0112] On the other hand, the barrel 600 also allows the shutter 500 to be guided in translation (when it is in the open position).

[0113] For this purpose, it has two elongated openings forming two guide grooves 620 in which ribs 512 provided on the foot 510 of the shutter 500 slide when the latter is in translation (figures 4, 6, 8 and 9).

[0114] These guide grooves 620, here two in number, are provided in the side wall 630 of the barrel 600 which they pass through completely. They extend in opposite directions from each other, parallel to the central axis Al. They are closed at the rear at the level of the bottom 610 of the barrel 600 by a rear end portion 631 of the side wall 630 of the barrel 600 and open at the front into central cutouts 212 provided in the bottom wall 201 of the insertion well 200 on the edge of the mouth 600A of the barrel 600.

[0115] In addition, the two ribs 512 are positioned projecting from the cylindrical wall 513 of the foot 510, along two diametrically opposed generatrices (Figures 5 and 6). The two ribs 512 extend parallel to the central axis A1 and have rectangular cross-sections. The ribs 512 extend straight along the foot 510 of the obturator 500 from its head 520 to its rear free end. Each rib 512 has a rear end face 512A extending near the rear free end 510A of the foot 510, orthogonally to the central axis A1

[0116] The ribs 512 of the foot 510 of the obturator 500 are oriented such that, when the obturator 500 has pivoted into the open position, they are located in the axis of the central cutouts 212 (figures 3 and 6) made in the bottom wall 201 of the insertion well 200, so that they can engage there and thus release the piston 300's displacement mobility.

[0117] The guide grooves 620 are long enough to allow the ribs 512 to slide freely within them, without being obstructed by the rear end portion 631 of the side wall 630 of the barrel 600 when the shutter 500 reaches its lowered position. The ribs 512 come into contact with the rear end portion 631 of the side wall 630 of the barrel 600 when the shutter 500 reaches its lowered position ([Fig. 8]). The guide grooves 620 also have rectangular cross-sections adapted to those of the ribs 512 of the foot 510 of the shutter 500.

[0118] The barrel 600 also helps to retain the return spring 650. The return spring 650 is in fact interposed between the bottom 610 of the barrel 600 and the part of the rear face 520C of the head 520 of the shutter 500 which closes the front end of the foot 510 of the shutter 500.

[0119] The return spring 650 is thus secured to the insertion well 200, which means that, when the front element 710 is removed from the base 100, the return spring 650 remains interposed between components of the front element 710, namely the shutter 500 and the barrel 600.

[0120] The return spring 650 is advantageously a compression and torsion spring, which allows it to return the shutter 500 to the closed position when the electrical plug is extracted from the insertion well 200.

[0121] In compression, the return spring 650 acts to maintain the head 520 of the obturator 500, and more particularly a front face 520A of said head 520, in contact with the rear face 301B of the main wall 301 of the piston 300 ([Fig.5]) and thus return the piston 300 to the standby position when no force is exerted on it.

[0122] To act in torsion, the ends 651, 652 of this return spring 650 ([Fig. 1]) are also respectively blocked in rotation around the central axis Al relative to the obturator 500 and relative to the barrel 600.

[0123] For this purpose, they are folded to extend along a diameter of the return spring 650. Correspondingly, the bottom 610 of the barrel 600 and the part of the rear face 520C of the head 520 of the shutter 500 each have two ribs (not shown) which delimit between them a groove for receiving the corresponding end 651, 652 of the return spring 650.

[0124] This return spring 650 then acts in torsion around the central axis Al, to return the obturator 500 to the closed position when no force is exerted on it.

[0125] When the piston 300 is in its actuation position at the bottom of the insertion well 200, the return spring 650 is compressed inside the foot 510 of the obturator 500.

[0126] Thus, since the barrel 600 retains the return spring 650, the front element 710 of the power socket 700 comprises, by itself, all the mechanisms enabling the piston 300 to move within the insertion well 200. The power socket 700 is therefore modular in the sense that the front element 710 can be detached from the base 100 while still securely holding all the other components together. The shutter 500 itself provides electrical safety for the front element 710.

[0127] Advantageously, the front element 710 also includes disengageable locking means 560 adapted to block the shutter 500 in translation when it is in the closed position.

[0128] Thus, in the closed position, the obturator 500 is locked in the upper position, which advantageously allows, thanks to the arrangement of the obturator 500 immediately under the piston 300, the piston 300 to be locked in the standby position.

[0129] The locking means 560 can be disengaged solely by moving the shutter 500 from its closed position to its open position.

[0130] These locking means 560 prevent a simple press on the piston 300 from pushing it backwards when the shutter 500 is still in the closed position.

[0131] In this case, these locking means 560 are formed on the one hand by stop surfaces 511, here two in number, belonging to the ribs 512 of the foot 510 of the obturator 500 and by bosses 550, also two in number, projecting from the bottom wall 201 of the insertion well 200 (figures 3 and 6).

[0132] As shown in [Fig. 6], each abutment surface 511 corresponds more particularly to a peripheral lateral portion of one of the rear end faces 512A of the ribs 512 of the foot 510 of the shutter 500. The abutment surfaces 511 thus extend orthogonally to the central axis AL

[0133] As shown in [Fig.6], the bosses 550 are positioned along the edge of the mouth 600A of the shaft 600 in the insertion well 200, in a diametrically opposite manner.

[0134] As clearly shown in [Fig. 6], each boss 550 is positioned to correspond with one of the two stop surfaces 511 so that, in the closed position, the stop surfaces 511 are placed on the bosses 550. Alternatively, the stop surfaces could very slightly overhang the bosses. Thus, at the slightest pressure on the piston 300, the stop surfaces 511 come into contact with the bosses 550, which locks the piston 300.

[0135] Each boss 550 more specifically has a bearing face 550A ([Fig.6]), intended to receive one of the two abutment surfaces 511, which extends (like the abutment surfaces 511) orthogonally to the central axis Al of the insertion well 200. This ensures effective locking of the abutment surfaces 511 on the bearing faces 550A of the bosses 550.

[0136] As shown in [Fig. 6], each boss 550 is generally rectangular in shape, rising along the central axis A1 from the bottom wall 201 of the insertion shaft 200 to its bearing face 550A, which thus defines its front end. Each boss 550, however, has an inclined face 550B which extends from its bearing face 550A towards the central cutout 212 made in the bottom wall 201 of the insertion well 200 for the passage of its associated rib 512, the inclined face 550B being transverse to the central axis Al. In this case, each inclined face 550B forms an angle of approximately 45 degrees with the central axis Al of the insertion well 200. These inclined faces 550B facilitate the raising of the obturator 500 into the closed position. Apart from the inclined faces 550B, the bosses 550 have cross-sections with a shape substantially identical to that of the ribs 512 of the base 510 of the obturator 500. The bosses 550 are formed here with the bottom wall 201 of the insertion well 200.

[0137] The height of the bosses 550 is such that the piston 300 is effectively locked in the raised position flush with the front face 221A of the trim piece 220, although the ribs 512 extend at a distance from the free end 510A of the foot 510. The bosses 550 effectively allow the support of the ribs 512 (when the shutter is in the closed position) to be raised towards the front opening 200A of the front element 710.

[0138] Thanks to the bosses 550, it is thus possible to lock the piston 300 in the standby position even though the ribs 512, which delimit the stop surfaces 511, extend at a distance from the free end 510A of the foot 510 of the obturator 500. Without these bosses 550, the obturator 500 would be blocked by the bottom wall 201 of the insertion well 200, and would therefore not be blocked flush with the trim 220, the height of the ribs 512 being limited by the presence of the bottom 610 of the barrel 600 (holding the return spring 650) and by the depth available to house the barrel 600 in the rear part 100B of the base 100.

[0139] The height of the bosses, along the central axis Al, between the bottom wall 201 of the insertion shaft 200 and their bearing surface 550A, is for example between 0.5 mm and 2 mm.

[0140] As clearly shown in [Fig.9], when the shutter 500 is in the lower position, the bosses 550 are advantageously housed in recessed housings 530 provided in the head 520 of the shutter 500.

[0141] Remarkably, each recessed housing 530 is indeed shaped to accommodate a boss 550 projecting from the bottom wall 201 of the insertion well 200. Thus, the rear face 520C of the head 520 of the obturator 500 fits the shape of the bottom wall 201 of the insertion well 200 (figures 4, 8 and 9), which allows maximum penetration of the piston 300 into the insertion well 200.

[0142] Thanks to the recessed housings 530, it is thus possible to achieve a piston stroke 300 of 17.8 mm between its two extreme waiting and operating positions, in order to correspond to the German standard.

[0143] As shown in Figures 4 and 8, each recessed housing 530 is here an opening that passes through one of the wings 521, 522 of the head 520 of the shutter 500. The The recessed housings 530 here have a rectangular section adapted to that of the bosses 550. Of course, these recessed housings could be closed-bottomed recesses that open only onto the rear face of the obturator head.

[0144] Furthermore, as shown in [Fig.8], the inclined faces 523, 524 of the wings 521, 522 of the obturator 500 generate additional thicknesses on the rear face 520C of the head 520 of the obturator 500. In order to prevent the wings 521, 522 of the obturator 500 from interfering with said bottom wall 201 and limiting the sinking of the piston 300 when the head 520 of the obturator 500 is pressed against the bottom wall 201 of the insertion well 200, the openings 210 of this bottom wall 201 are enlarged to accommodate said additional thicknesses.

[0145] The front element 710 also includes stop means (not shown) for blocking the rotation of the obturator 500 in the closed position. In other words, these stop means prevent the obturator 500 from leaving its closed position (as opposed to its open position). These stop means, against which the longitudinal edges 520B of the head 520 of the obturator 500 bear, are projecting from the rear face 301B of the main wall 301 of the piston 300.

[0146] We can now describe the movements of the different components of the power outlet 700 when an electrical plug is inserted into the insertion well 200 of this power outlet 700.

[0147] Initially, as shown in Figures 3 and 5, the piston 300 is held in the standby position by the return spring 650.

[0148] The shutter 500, which is held in the closed position by the return spring 650, then prevents dust particles from entering the power socket 700 and prevents a simple press on the piston 300 from causing it to sink into the insertion well 200.

[0149] The movable flap 150 is held in the closed position by the spring blade 160.

[0150] Then, when a user inserts an electrical plug into the power outlet 700, the prongs of this plug pass through the openings 304 of the piston 300 and bear against the inclined faces 523, 524 of the shutter 500, causing the latter to pivot. The ribs 512 of the shutter 500 then align with the central cutouts 212 of the bottom wall 201 of the insertion well 200 and the guide grooves 620 of the barrel 600.

[0151] The electrical plug then penetrates further into the insertion well 200. Such an intermediate position is shown in [Fig. 7]. The electrical plug progresses in the insertion well 200 until its prongs pass through the openings 111 in the cover 110 and come to rest against the inclined faces 152A of the flap mobile 150, which causes the mobile flap 150 to translate towards the release position.

[0152] The electrical plug is then free to move to the bottom of the insertion well 200 so that the base of the electrical plug holds the piston 300 in the operating position (Figures 4, 8 and 9). The pins of the electrical plug engage in the phase 130 and neutral 131 connection terminals.

[0153] Removing the electrical plug from the socket 700 causes the reverse movement of the various components of this socket 700, thanks in particular to the return spring 650 and the spring blade 160.

[0154] The invention is not limited to the embodiment described and represented and any variant in accordance with the attached claims could be envisaged.
