Definitions
- the present invention relates to an electrical socket for connecting a power source to an electrical / electronic apparatus.
- the existing European sockets are used with plugs to transmit current to their appliances.
- the plug part In order to do so, the plug part must be placed inside the socket and plug pins in reliable contact with socket connecting terminals.
- the plug is retained within the socket through the clipping effort done by terminals on pin parts.
- a pulling force of certain degree must be applied (depending on the tolerance of the plug pins and socket terminals as well as plug and socket housing eventual friction).
- An excessive pulling effort may damage the socket or its enclosure fixing parts.
- a non- sufficient pulling effort by elder or handicapped user may be ineffective for this purpose.
- an electrical safety plug which comprises a housing having an upper part and an inner lower part in which connection terminals are fixed, a lifting plate coupled to an inner part of the housing and moving vertically.
- the lifting plate comprises at least one insertion hole in which a connector pin of a connector is inserted to connect to the connection terminals.
- a pressure on the plug pins on shutter system will move the movable plate inside the socket and reaching an engagement position, the shutter flaps will turn allowing the plug pins to couple the socket terminals.
- the lift operation unit performs a vertical press operation to lock the movable plate at that engagement position.
- the lifting plate When the lifting plate is pressed inwards by plug, the lifting plate is released by lift operation unit and moved upward to space the terminal pin of the connector terminal connector and "release" the connector.
- the lift operation unit responsible of locking and unlocking the plate, will only work when the plug pins are inserted and contact an element (pressing protrusion) of the lift operation unit.
- That lift operation unit relies on vertical movement of that unit for its operation as well as continuous contact with central bar of lifts plate.
- the disadvantage of this solution is that is not possible to stand the European standards which request at least 10,000 cycles for safety shutter opening and closing. A premature ageing of those parts will eventually happen with a single (vertical) locking/unlocking system.
- a socket comprising a casing housing at least two connection terminals, a trim mounted at the front of the casing and having two access openings at said connection terminals, and a rear shutter having two wings.
- This rear shutter secured to the housing, is movable between a closed position in which its wings prohibit access to said connection terminals and an open position in which they allow this access.
- a flap closing the cross-section of this well movable in translation with respect to said cylindrical wall, comprising at least two orifices, - a central pillar adapted to slide axially in a groove to translate together with the flap,
- a shutter mounted at one end of the central post adapted to pivot between a position for closing off said orifices of the shutter and a position for opening said orifices
- the shutter is free to pivot with respect to said central post between its open and closed positions.
- This system improves the previous EP 2 555 336 by returning the cylindrical wall to its waiting position without taking into account the position of the flap (depressed or not). As soon as the pins are no longer in contact with the active parts, the cylindrical wall slides upwards (waiting position).
- no conventional electrical socket for connecting a power source to an electrical / electronic apparatus, allows to uncouple, easily, the plug with simple pressure on the surface plate while keeping all the necessary features from a secure plug.
- An object of the present disclosure is to alleviate the drawbacks and insufficiencies resulting from the above-mentioned prior art.
- an electrical socket comprising:
- - a base comprising terminals configured to be connecting to mains
- a casing mounted on said base and comprising an inner tubular wall extending along an axis of engagement oriented towards the base,
- a movable plate coupled to the inner tubular wall of the casing and configured to translate along the axis of engagement between a waiting position and a locking position, and vice versa
- said at least one locking system comprises:
- Such a configuration of locking system provides a locking/unlocking solution that is simple, effective, robust/durable and space saving. Moreover, the manufacturing costs of such a locking system are low.
- the stopper when the movable plate moves up to the position where the stopper is located, the stopper is configured to exert a pressure on an inner portion of the movable plate to fixe the movable plate in the locking position.
- the stopper and the two asymmetrical springs are coaxially mounted on the bar, and wherein the stopper is disposed between the two asymmetrical springs.
- Such asymmetrical springs are a simple and effective solution to offset the stopper at a lower cost.
- the movable plate comprises:
- each leg is configured to slide into a first groove formed in the inner tubular wall of the casing and into a second groove formed in the base.
- each leg comprises an inner groove and an upper groove, the inner and upper grooves are configured to interact with said at least one locking system.
- Such a configuration makes it possible to simplify, at a lower cost, the structure of the locking system by placing certain elements of the locking system directly on the guide elements.
- each leg is configured to interact with one locking system.
- the inner and upper grooves are configured to interact with the stopper.
- the inner groove is configured to:
- the movable plate comprises a safety shutter.
- Such a shutter improves user(s) safety.
- the electrical socket further comprises means for fixing the base to a desktop.
- Such a configuration makes it easier to fix a socket according to the present disclosure onto a desk.
- the present disclosure also relates to a multiple extension lead comprising a plurality of electrical sockets as previously described.
- Such a configuration makes it possible to connect a plurality of plugs into sockets according to the present disclosure.
- the present disclosure relates to a socket in which the extraction means comprise, on the one hand, elastic thrust elements and doubled coupling and decoupling elements that are mobile by parallel and perpendicular translation to the socket.
- the movable plate can move in translation without the need for an electrical plug, just by means of a pressure on its surface.
- said movable plate arrives at the locking position, its contacting surface slides into the base grooves where stoppers of double locking system will contact and block the inner grooves of sliding surfaces.
- the inwards pressure of the movable plate releases itself from stoppers displacing them along their bars.
- the return of the said movable plate to the waiting position can be carried out with a slight pressure on the plated towards the inside of the socket.
- the locking system perpendicular to the axis of engagement blocks the movable plate when matching the upper area of inner groove. It does not touch the connecting terminals neither interacts the safety shutter.
- a vertical movement (inwards) of the movable plate allows itself to be released, pushed up by the springs and move along the axis of engagement till arriving the upper ending of the casing groove.
- the two independent elements make a reliable solution for enduring a high number of function cycles.
- the movable plate can be locked with a pressure on its whole surface, it is easy to plug no matter the emplacement or the user ability. As explained, the movable plate will only unlocks itself from stoppers if a pressure inwards is exerted.
- the movable plate In case of forcible unplug, the movable plate will remain at locking position as it does not depend on the physical contact with plug pins to remain in that position. Therefore, it will be ready for a new plug to couple directly with connecting terminals and safety is ensured by shutter system on movable plate.

- the present invention relates to a system to help uncouple the plug with simple pressure on the surface plate while keeping all the necessary features from a secure plug.
- Figure 1 shows an electrical wall socket (1) designed to receive a complementary electrical plug for the connection of this plug to mains.
- This product is fixed to recessed box typically through screws to be tightened through the orifices (65) on frame support (61).
- this casing (6) is made of insulating material, for example by molding a plastic material.
- Figure 3 shows the system for connecting this electrical socket (1) to the mains. This is done on backside of the base (8) through terminal holes (83) secured by screws. As soon as the wire plugs into, the tightening of the screws (81) will secure the wires inside the base (8) ensuring the contact of wires with connecting terminals (10).
- Figure 4 shows the movable plate (4) of the electrical socket (1), which can be displaced, in translation from a waiting position along the axis of engagement (A) (figure 2), to a locking position, and vice versa.
- each locking system (9) comprises a stopper (93) located in a side of a metallic bar (92) due to the length of a larger spring (91), named first spring (91).
- the smallest spring mounted on the metallic bar (92) is named second spring (95).
- Figures 2 and 4 show the movable plate (4) for sliding in translation along the axis of engagement (A) by the inner tubular wall (63) of the casing (6) from the waiting position (I) towards the inside of the base with a multiple guiding system:
- the rectangular legs (45) traverse a downward first grooves (64) inside the casing (6) arriving at the second grooves (84) of the base (8) parallel to the axis A.
- FIG. 5 and figure 6 show an exploded view of this movable plate (4).
- the movable plate (4) comprises:
- the inner tubular wall (63) is substantially cylindrical.
- the safety shutter (43) is housed between the outer surface (41) and the first housing (44) and uses the two elements for its operation.
- a detail of rectangular legs (45) and their inner grooves (47) is also displayed in that view.
- FIG 7 it is shown the middle part (5) that is fixed to base (8) by four bottom screws. That middle part (5) holds the connecting terminals (10) avoiding any unintended access out of surface cleared by safety shutter (43).
- the plastic wall (51) separates the connecting terminals (10) from the area (52) where the locking system (9) is placed avoiding any interaction between them.
- FIG 8 it is shown the base (8) where the two locking systems (9) are located as well as the round tubes (82) for placing the main springs (7).
- FIG. 9 shows all the elements of each locking system (9).
- Each locking system (9) comprises:
- the stopper (93) is able to move in the surface perpendicular to the axis A when touched by inner grooves (47) of movable plate (4) and it will try to return to the resting position determined by the elasticity of the first springs (91) and the second springs (95).
- FIG 11 it is shown the different elements combined in waiting position (I) and main springs (7) are in released position. As displayed, the movable plate (4) is in the most external position of the socket. The stoppers (93) of locking systems (9) are in their resting position and not interacted by inner grooves (47) of rectangular legs (45).
- FIG. 13A and 13B it is shown the arrival to bottom of the movable plate (4) along the cylindrical wall (63) of casing (6).
- the movable plate (4) keeps descending (figure 13A) and displacing the stoppers (93) from resting position to its furthest position on the right.
- each stopper (93) will face the left salient of the inner groove (47) as well as its lower part blocking its leg to keep moving it up.
- the stoppers (93) pushed and pulled by the first and second springs (91, 95) respectively of its locking system (9) are exerting pressure on the left salient of inner groove (47).
- the stopper (93) can only move along the longitudinal axis defined by the metallic bar (92) and tends to come back to its resting position on left area.
- Each locking system (9) blocks one of the rectangular legs (45) of movable plate (4).
- a locking system (9) is associated with a rectangular leg (45).
- That locking position matches the optimal emplacement of the movable plate (4) for ensuring a reliable connection with terminals (10) if a plug is coupled to.
- a pressure on outer surface (41) of the movable plate (4) towards inside the socket base (8) will push the rectangular legs (45) slightly down.
- the left salient of inner groove (47), of each rectangular leg (45), will not be in contact with the stopper (93) anymore, as shown on figure 15B.
- the stopper (93) is pushed to the left by the combined effort of its two first and second springs (91, 95). That movement is independent from the movable plate (4) and linked to the internal construction of the locking systems (9).
- FIG. 16A and 16B it is shown how the movable plate (4) and the stopper (93) follow their independent path vertically and horizontally respectively.
- the stopper (93) will returns (figure 16A) to resting position while the movable plate (4) is being pushed up by the main springs (7) until returns to waiting position (I) as shown on figure 16B.
- the movable plate (4) and locking systems (9) are independent elements that interact for ensuring an optimal position of movable plate (4) and guaranteeing a reliable contact of terminals (10) with plug pins.
- the locking systems (9) will be in charge of blocking the movable plate (4) at the position above mentioned when movable plate (4) is returning from bottom position.
- the movable plate (4) will release itself from the locking systems (9) when a pressure inwards on the movable plate (4) is exerted. Those two locking systems (9) remain independent except for the minimum interact for ensuring a locking position at the desired emplacement.
- Figure 17 shows an equivalent solution for the German standard, the elements used for its realization are those of the Franco-Belgian version with the dimensional and shape differences of the electrical plug for Germany.
- the shape of the movable plate (4) and the first housing (44) is indeed different as well as the location of the small spring (42) of the safety shutter (43). Also the distance between the plate (4) and the connecting terminals (10) follows the German standard although these differences do not bring substantial changes to the technical solution chosen.
- Figure 19 shows the rear view of the elements to show that the changes made are only those indicated previously.
- Figure 20 shows a solution specially conceived for desktop or kitchen table. Since most of this furniture is provided with pre-cut holes of 60mm for cable management, an extension lead that takes advantage of these features as well as remains flat are embedded into desktop.
- the base (8) of the extension lead will pass through the hole pre-cut on desktop (11) and fixed by a threaded part (12).
- the casing (6) will be retained outside the desktop (11) and the outer surface (41) of movable plate will remain flat with table when not displaced inwards.
- Figure 21 shows the product ready to use in an optimal display blending in the desktop at its waiting position.
- Figure 22 shows an alternative construction especially suitable for elder and handicapped. Since most of wall sockets are located at minimum height from floor, it is not convenient for them plugging and unplugging appliances.
- a multiple extension lead fixed to wall and providing several socket outlets with this technical solution will solve the double problem of reaching and extracting the plug when used.
- a duct tube (21) houses the extension cord which plug (22) will be connected to the existing wall socket.
- the present invention is in no way limited to the shape of the socket or its connection to the mains; it is indeed possible to envisage changes in the size or shape or a connection system using screw terminals.
- the electrical socket is here adapted to be housed in a box embedded or protruding on any wall. In a variant, it may be an electrical socket of the extension type, a multiple socket.
- the present invention can also be adapted to any type of electrical plug adapter, for example an extension cord, a reel or a wall adapter as well as to add other functions to this solution via an independent electronic board.
