Description

"CURRENT OUTLET WITH BOX AND CURRENT EARLY DEVICE DEVICE".

Field of the invention

The present invention relates generally to electrical current outlets of the type comprising a housing suitable for receiving a complementary electrical disconnect plug.

More particularly, it is intended for those which comprise, on the one hand, a folding shutter, more commonly called, in a simplified manner, "eclipsed" or "eclipse", which, contrary to the elastic means of the surrounding, is movably mounted on its between an unfolded resting position, to which he conceals the passage openings located directly in his contact wells, thereby denying access to these contact wells, and a retracted service position to which, properly eclipsed, he releases these openings and allows This provides access to these contact wells and, on the other hand, a movable protective flap that prevents the deposit of dirt on the inside of the box.

Thus, the folding shutter thus applied constitutes a safety device which, in a resting position, precludes any element, for example, metallic, unfortunately introduced, for example, by a child, into one of the passages of the element, before it can reach the corresponding contact socket, this one is normally under voltage.

Background of the invention

It is known from the prior art that the casing sockets with a movable flap provided with a folding shutter are known. More particularly, one type of socket is known in which the translation of the flap into the housing is locked by the translational closing means, which are disabled when inserting a plug. In this type of socket, the introduction of the complementary plug-in electrical plug releases the transitioning tab and causes it to move, thus allowing access to the internal electrical contacts in the socket. In practice, it is this shutter displacement that disables the translational closure means.

The plug pins traverse the tab after the pushing process in the middle of the plug, as a result of which the tab moves axially into the datum box and the plug pins finally come into contact with the socket contacts. In this type of socket, the plug can then engage through the tab without making contact with the electrical contacts. At the time of removal of the plug, the flap rises again to the top of the box under the action of return means, the shutter closes again under the action of return means after the extraction of the plug, which results in the activation of the means of closing the translational shutter. tab in the box. Such an outlet is especially known from the FR2886775 document.

Well known plugs offer overall satisfaction. However, we would like to improve the safety of the movable and shutter tabs, particularly by allowing the latter to open only when the plug is in a position where its pins are likely to be. contact with the pins, so as to leave the shutter closed at any other time, thereby preventing access to the electrical contacts.

In general, the present invention is intended to improve this type of outlet, particularly in the field of safety.

More precisely, the invention is directed to a boxed power socket comprising directly on its bottom of the box the electrical contacts for an electrical connection plug having the complementary electrical connection pins and comprising:

a housing protection flap provided with holes provided for the passage of the movably-mounted electrical connection plug pins in the housing between a top position, in which it is substantially projected out of the housing edge and a lower position therein is at its limit support against the bottom of the box, a means of return permanently requiring aaba to the upper position,

a plug for the pin through holes arranged in the flap, the plug being movably mounted on the flap and formed to move in a plane parallel thereto formed by the flap near a closing position in which it covers the through-holes of the pin thus restricting the access of the pins to the electrical contacts to an opening position in which it authorizes such access, a means of return permanently requesting the shutter to return to the closing position,

The socket being characterized by comprising the shutter closing means to prevent it from passing from the closing position to the opening position, the closing means being suitable for activation when the flap is in the upper position. Thus, the safety of the socket is advantageously improved. as the shutter is locked in the closed safety position while the flap is in the upper position.

According to an advantageous aspect of the invention, possibly combined, the closing means are suitable to be deactivated when the flap is in the lower position, allowing the shutter displacement of the closing deposition to the contact position of the pins of the complementary connection plug in connection phase. plug, thereby allowing the plug pins to access the corresponding electrical contacts, lying directly at the bottom of the box.

Thus, advantageously, the opening of the shutter and thus access to the electrical contacts is authorized only in the lower position of the flap. At the moment of insertion of the plug into the box, under the effect of the displacement of the plug, the flap first passes from the upper to the lower position, and it is only at this moment that the shutter is unlocked when the pins are closer to the electrical contacts seen on the other side of the plug. tab. Safety is significantly improved as access to electrical contacts is only allowed at the last moment. Please note the advantageous, if not combined, features:

the shutter is adapted to rotate between the closing position and the opening position, a return spring permanently requesting it to its closing position, and the closing means of the shutter are the rotation locking means;

- the rotation locking means is adapted to operate with a means provided in the housing wall to activate said rotating locking means when the flap is in the upper position in the box and to disable said rotation locking means when the flap is in the lower position in the box;

- the rotation locking means comprises a slot in the housing wall and a bayonet pin making the rotary shutter relief to the housing wall and intended to fit into the slot, the slot being profiled such that

. when the flap is in the lower position in the housing, the groove has an extension that allows the pinionionette a degree of freedom in the plane parallel to that formed by the flap, the extension being sized to allow shutter rotation from its closing position to its closure. opening position.

You are then taking advantage of the movement of the bulb caused by inserting the plug to release the shutter rotation. The translation of the flap in the box releases rotation and therefore the possibility of opening the shutter.

According to an advantageous feature of the invention, the pinobaioneta has a chamfered shape and the groove presents, between its narrow portion and its extension, a complementary knife designed to cooperate with the chamfer, thereby transforming a translational movement of the upper position into a bevel. rotating movement of the shutter to its closed position through its bayonet pin so that the shutter is in a closed position before the bayonet pin penetrates the narrow groove section thereby allowing the aaba to return to its upper position.

Advantageously, according to this last feature, the return of the flap is possible only when the shutter is closed. The co-operation of shapes between the bayonet pin and the armpit advantageously permits the effort of the flap return means to be moved to the upper position as the shutter rotates. This contributes to the safety of the socket according to the invention by preventing a coincidence of the flap with the plug in the open position at the bottom of the housing.

According to an advantageous feature of the invention, the shutter is shaped to transform the translational movement of the pins of the electrical connection plug being introduced into the rotating socket around it.

Thus, according to the invention, the shutter is shaped to transform the movement of the pins of the mains plug into the mains socket, rotating around it, to move from the closing position to the opening position by rotating. about elemesmo. Thus, once the flap has left the upper position and the rotating shutter closure is released, the translational movement of the plug introduction is taken advantage of to open the shutter and authorize access to the electrical contacts.

For the supply of certain electronic devices, such as calculators, it is desirable to have a better quality electrical distribution network and particularly greater stability, stability and good protection against micro-interruptions. reserved for the supply of appliances of this type to prevent the occasional connection of another electrical appliance from affecting stability or introducing interference. Advantageously, the present invention avoids such a faulty connection. It therefore proposes an outlet as described above whose shutter is adapted to transform the movement of the plug into rotation in contact with a specific anti-ground device. for atomada, mounted on the connecting plug for this purpose, the anti-tamper device being the only means for transforming the translational movement of the plug in the process of introduction into shutter rotation,

Thus, advantageously, the present invention is used to prohibit access at a given outlet to plugs which are not provided with a corresponding anti-tamper device. In other words, as per this feature, it is necessary to have an external device to be able to use this socket. In this case, the anti-roll device becomes a type of switch that allows you to use a power outlet and therefore access to a certain power grid.

According to an advantageous aspect, the obturator has a projection disposed in its plane of rotation, and whose end is shaped like a ramp, and the antierro device has a finger whose end is formed in a bevel shape to cooperate with the armpment of the obturator arm. to turn the movement of the anti-roll device and plug movement into the introduction stage, and to rotate the shutter from its closing position to its open position. It then takes advantage of the transitional movement of the plug and anti-roll device introduction to open the shutter. and authorize access to electrical contacts.

In another aspect, the invention also relates to an anti-tamper device and a socket such as that described above, the anti-tamper device having a perforated plate of holes that let the plug pins pass through and allow access to the plug's eventual electrical contact sockets. the plate being intended to be placed at the end of the plug and having means for transforming the transitional movement of the plug into the plug-in rotation phase in cooperation with the complementary means provided for that purpose at the socket.

It should be noted that whatever the decoding modes, the socket and particularly the housing, the flap as well as the shutter may have a different number, a different distribution and shape of the pin holes, so as to adapt to different geometric dimensions of electrical outlets and complementary mains plugs, particularly for different grounding pin positions, particularly depending on the standards and standards in force in a given country.

Generally speaking, the present invention applies to all type of flap box outlets, whatever their electrical standard (number of pins, shape of pins, distance between pins, shape of plugs, etc.).

Description of the invention

As can be seen from Figure 1, a power socket 100 according to the invention has a base 600 on which a housing 200 is mounted on which a movable flap 300 is mounted.

As this is most noticeable in Figure 2, base 600 is provided with contacts 500 held in place by a plate 400 which inserts into the bottom of base 600.

The movable flap 300 is mounted for translation in the aqual box 200 and in turn inserts itself into the base 600 above the plate 400.

The 400 plate is drilled with holes for the passage of the plug pins to be connected to the 500 contacts.

Two supportive shoes 302 of flap 300 are provided to secure the return of the flap to the upper position by outcropping with the edge 201 of the box 200. The return is through the middle of two coil springs 601 which abut the bottom of the base 600 and whose opposite ends fasten, themselves in tapered pins 303 provided for this purpose at the ends of the shoes 302.

The movable flap 300 houses a shutter 350 covered with a decorative piece 301 showing the holes for passing through the pins of a plug intended to be connected to contacts 500.

Shutter 350 is visible, more particularly, in Figures 3A and 3B. Shutter 350 has a central ring 351 and two ears 352 for closing the through-holes of pins 304 arranged in flap 300.

Advantageously, the central pin pass hole 305 is circled from an edge 306 forming a pin serving as a hub for shutter center ring 351. In use, the central pin pass hole 305 is intended for the passage of a grounding pin and therefore it is not provided with a shutter. A return means in the form of a coil spring 307 is provided to permanently request the plug to the closing position as illustrated in Figure 3A. The spring 307 rests on a bracket 308 provided on flap 300 and, on its opposite end, on a flat surface 354 provided in the central ring 351 of the plug. This flat surface 354 is provided with a tapered pin 355 spring guide according to the same principle as pins 303. Two brackets 309 are provided on tab 300 for defining shutter closure, the two ears 352 being limited to brackets 309 under the effect of return dam action 307.

Thus assembled, the shutter is adapted to move in rotation following a plane parallel to the plane of flap 300 to the closing position as illustrated in Figures 3A and 3B.

A bayonet pin 356 is provided projected on the central ring 351 of the shutter 350 to serve as a locking means for the latter. A slot 202 is provided in housing 203 of housing 200. Bayonet pin 356 protruding from shutter 350 is sized to fit into slot 202.

As can be seen, more particularly, in Figure 3B, the slot 202 has at its proximal end of the box 201 a narrow section 204, and at its lower part the slot has an extension 205. Thus, when the tab 300 is in the upper position in the box 200 as illustrated in Figure 3A, bayonet opinoid 356 is in narrow section 204 of knurl 202, which prevents shutter rotation 350. When the flap 300 has been moved to the lower position, as shown in Figure 3B Under the effect of inserting a plug not shown, the bayonetase pin is at the level of extension 205 of slot 20, which allows the rotation of the plug from its closing position to its opening position as can be seen in Figure 3B.

As can be seen particularly from Figures 3B, 4A and 4B, the bayonet pin 356 has a dechanter shape. The groove 202 has between its right portion 204 and its extension 205 an additional ramp 210 designed to cooperate with the pinionion notch 356. Thus, in cooperation with the ramp 210, a translation movement of the flap 300 towards the upper position generated by the springs 601 is a shutter movement in the direction of its closing position through the chamfered portion of the bayonet pin before it penetrates into the narrow section 204 of knurl 202. This arrangement avoids, on the one hand, the open position locking of the shutter 350 when aaba 300 se It is located at the bottom of the housing and, on the other hand, facilitates the return of the bayonet pin in the narrow section204 of the slot 202 to thereby allow the hood to rise to its upper position as shown in Figure 3A.

The plug is adapted to transform the pin-transfer movement of an in-phase plug-in plug (not shown) into the rotating moving socket around itself, with the aid of the sliding profile 357 provided on the ears 352 as a known arrangement as such. . In practice, when a plug is inserted into socket 100 according to the invention, the translation of the pins results in a translation of the tab 300 from its upper position emerging in the direction of its lower position as the bayonet pin 356 is fitted into the narrow part 204 of the slot 202, o made all shutter rotation possible. Once the lower position is reached by the tab 300 under the effect of inserting the plug, the bayonet pin 356 is released at extension 205 of the slot, and the plug may snap thereon under the effect of the introduction of the pins by the effect of the ramps 357 as opposed to the opening. return spring 307. Thus, access to contact 500 is authorized for the pins only when they are in close proximity to said contacts. In other words, electrical contact is authorized only at the last moment.

Upon removal of the plug, bayonet pin 356 prevents the rise of flap 300 until the shutter is not closed. Once the plug is removed, the plug closes under the effect of spring 307 combined with the effect of ramping the chamfered portion of bayonet pin 356 in cooperation with ramp 210 under the effect of return springs 601. The shutter then automatically moves to the locked position. against the brackets 309 and the bayonet pin 356 passes into the narrow portion 204 of the slot 202 before rising with the flap to the top position emerging under the effect of return springs 601. Advantageously, it is understood that the shutter closure is systematically secured to the entire end. possibility of rising again to the upper position when the plug is extracted. The co-operation of the ramp 210 and the bayonet pin portion 356 prevents the interference of the shutter in the open position. In the device according to the invention, the position of the plug fitting, that is, of letting the plug pass to the other side of the plug plane during Lowering the shutter towards the bottom electrical contacts of the box became impossible.

Another embodiment of a socket 101 according to the invention is shown in Figures 5 to 7. This embodiment is particularly suited to protecting a better quality electrical distribution network from the occasional or accidental connection of an inappropriate electrical appliance.

As in the preceding embodiment, and as noted in particular in Figure 5, socket 101 has substantially the same structure as socket 100 described above: socket 101 has a base 600 on which a housing 200 is mounted in which a transformer is mounted. movable tab 320.

The base 600 is provided with the contact 500 held in place by a plate 400 which inserts into the bottom of the base 600. As in the previous embodiment, the abutment 320 is mounted for translation into the box 200, which in turn inserts into the base. 600 above plate 400. Return of flap 300 to the upper position is effected in the same manner as in the preceding embodiment and will not be described in detail herein.

The plug 101 of plug 101 is very similar to the plug 350 of plug 100 described above. Bayonet 376 is particularly identical to pinion 356 as is the cooperation with the corresponding slot at housing level 200. The operation of the shutter rotation closure device is identical to the embodiment, hence, these elements will not be described further below. details here.

As seen in Figure 5, a plug 700 provided with an anti-tamper device 750 is intended to be connected to contact 500 of socket 101.

At socket 101, the shutter ears 370 are not ramped as in the previous embodiment, but have a flat section that does not allow the transformation of a transitional movement to a rotary shutter movement. Next, a projection 372 protrudes from the central ring 371 of the shutter 37 0. This projection 37 2 has a surface forming the ramp 37 3 intended to cooperate with the rod 51 of an anti-slip device 750 mounted on a plug 700 intended to be plugged into the socket. • The end of shank 751 has a chamfered shape designed to operate with the shutter ramp 373 so as to transform the pin transition movement in a shutter rotation movement.

A decorative piece 371 is provided to cover the flap-mounted shutter in a manner similar to the decorative part 301, except that it has a complementary hole 322 for the passage of the rod 751 of the anti-roll device 750.

The anti-roll device 750 and its placement on the plug 700 are more particularly observable in Figure 6A and Figure 6B. The 700 plug is a standard plug into which a 750 anti-roll device is adjusted. As most particularly noticeable in Figure 6A and Figure 6B, the 750 anti-roll device has a 752 perforated plate with holes that let the plug pins through, the plate being intended to be inserted. at the end of the plug and having a shank 751 whose end is chamfered to enable the translation movement of the plug to be introduced into rotation of the plug in cooperation with the complementary ramp 373 provided for this purpose.

According to a variant not shown, when the socket is equipped with a grounding pin, the anti-ground device plate is provided with a corresponding hole to allow access to a possible grounding contact socket of the plug.

As is more particularly apparent from Figure 7, rod 750 of anti-roll device 750 cooperating with shutter ramp373 is the only means of allowing the shutter to rotate itself in this decoding mode - Thus, it is not possible to insert a standard 700 plug not provided with the plug. 750 anti-roll device in a socket 101 according to the invention, because there is no element to allow the shutter to pass closed enclosure to the open position thereby allowing access to the electrical contacts of the socket pins. Advantageously, such a socket 101 protects a better electrical distribution network. quality of an occasional or accidental connection to an electrical appliance that is not appropriate. The 750 anti-roll device is in any way a switch allowing plug700 to access contact 500 from socket 101. Inserting and extracting a plug provided with an anti-roll device in socket 101 is about the same as inserting a plug into a 100tal socket. as described above, except that the anti-roll device 750 rod 751 which transforms the anti-roll device 750 movement of the plug into a shutter rotation movement at the limit to open the plug and allow the pins of the plug 700 to access contact 500.

Other embodiments could also be developed by specialists, in particular outlets featuring a round section.

Of course, the present invention is not limited to the embodiments described and shown, but encompasses all embodiments.

In particular, instead of being mounted movably in a circular motion, the applied plug could be mounted movably following a linear motion.
