Definitions
- This socket can be used for domestic energy distribution networks electrical, or for other applications such as control or telecommunication.
- This socket allows the use of plugs including the pins contact have a standard configuration, but which are original equipped, or can thereafter, a polarizing pin.
- EP-A-0 654 858 describes a keyed socket outlet socket, according to the preamble of claim 1 having a retractable shutter by displacement in rotation following an axial thrust exerted simultaneously on the studs by the pins of the plug.
- the central part of the shutter is shaped according to a spherical cap, to which three arm carrying a stud at each end.
- the shutter is mounted with play on the element cylindrical, and is more or less unstable in equilibrium on the base.
- polarized sockets provided with a safety device, especially for the protection of children, who prevent accidental contact by introduction of a conductive object such as a metal rod.
- a safety device comprises for example blocking means which close the openings of the socket the absence of a plug and which only retract if all the pins of a plug standard are introduced simultaneously.
- Any device with a plug standard can be connected provided that it is fitted with a standard plug. These takes do not allow relative allocation of the corresponding network to devices determined equipped with an adequate plug.
- the object of the present invention is to create a keyed socket providing a function safety against the introduction of any objects into the outlet openings and allowing a network to be assigned to a specific type of device, these devices being equipped with an appropriate plug corresponding to this socket.
- the coded socket 10 as shown in exploded view in FIG. 1, comprises an inner box 11, the upper face of which is provided with four openings 12, 13, 14 and 15.
- the openings 12, 13 and 14 correspond to contact parts in the form of female sockets intended to receive the male pins of a connection plug with three pins, one of the pins being the pin of earth provided for coupling with the earth socket mounted opposite the opening 14, and the other two pins being phase pins provided for mate with the phase sockets mounted opposite the openings 12 and 13.
- the opening 15 is intended to receive a so-called polarization pin which is either present on the card, or placed on an intermediate piece as will be explained later.
- the upper face of the inner housing 11 carries a locking device composed of a moving part 16 which is housed in a fixed cradle 17.
- the cradle 17 also contains two springs 18 which rest on the one hand on two lateral shoulders 19 of the moving part 16 and on the other hand against a wall inside of a peripheral rim 20 of this cradle 17. These springs have for function of pushing the moving part 16, and tend to maintain two protuberances side 21 of this piece bearing against the interior walls of two shoulders 22 formed by sections of the rim 20 of the cradle 17.
- All these components namely the inner box 11 and the components of the device locking, are mounted inside a cover 23.
- An auxiliary part removable 24 to be mounted on a standard plug 25 is provided to make this plug standard with three pins compatible with the socket according to the invention.
- FIG. 2 shows the fixed cradle 17 seen from below, and illustrates a housing 36 in which the moving part 16 moves.
- This cradle comprises a flat wall 30 in which are formed three through openings 31, 32 and 33 which correspond respectively to the openings 12, 13 and 15 of the upper face of the inner box 11.
- the rim 20 has in its rear part two housings 34 and 35 which are intended to receive the ends of the two springs 18.
- the rim 20 defines the two shoulders 22 against which the lateral protrusions 21 of the movable part are pushed into abutment by the springs 18. These shoulders 22 extend outwards by two fingers of retainer 37 each having a beveled end 38 and a guide surface 39 parallel and opposite to the same surface 39 of the other finger.
- FIG 3 shows the moving part 16 seen from above.
- the front of the part is on the right in the drawing.
- each of the lateral protuberances 21 of part 16 has, on its upper face, a plane inclined 40 directed towards the rear. Its front face constituting the shoulder 19 is provided with a cylindrical housing 41 for receiving the end of the spring 18.
- the body of the part 16 comprises two parallel branches 42 separated by a elongated central opening 43 and connected by a front stirrup 44 and a cross-member rear 45. Near its rear end, each branch 42 has a hook 46 likely to catch on one of the end bevels 38 (Figure 2) of the cradle 17, as shown in Figure 4.
- a locking lug 47 protruding with respect to this upper face substantially cylindrical is provided in the middle of the front caliper 44 and has a surface 48 slightly inclined towards the rear.
- Figures 4 and 5 show the locked position of the moving part 16 inside of the cradle 17.
- Figure 5 shows that the underside of the part 16 is not plane, but has a transverse bead 50 which defines a tilting axis of the part 16 when it rests on the upper wall of the inner casing 11 (figure 1).
- the support force F of the springs 18 acting on the protrusions 21 tends to tilt the moving part 16 towards the high, so that the lug 47 engages in the through opening 33 of the cradle 17 and is placed against a front edge 51 of this opening, thus locking the part 16 and preventing its movement in the opposite direction to the direction of the force F.
- the inclined planes 40 of each of the two protrusions 21 of the part 16 are arranged respectively opposite the openings through 31 and 32 of the cradle 17, and close both of these through openings and the openings 12 and 13 of the upper wall of the inner housing 11.
- the ends of the lateral protrusions 21 ensure that the part 16 is centered in the cradle 17, by sliding support against the lateral parts of the peripheral rim 20.
- they provide orientation of the moving part 16, such that the rear legs 42 of this part are centered between the two guide surfaces opposite 39.
- the hooks 46 do not touch these surfaces 39, because they are located beyond the ends 38 of the fingers 37 in this locking position.
- the components of the locking 16 and 17 are housed between the cover and the inner box 11.
- the fixed cradle 17 can be fixed to the housing 23 by any suitable means, in particular by fitting into corresponding cavities, but it can also be made as part of the cover.
- the latter presents externally four inlet openings 52 aligned with the openings 12, 13, 14 and 15 of the inner housing 11, three of them being further aligned with the openings 31, 32 and 33 of the cradle 17.
- the cover 23 may have a annular collar 53 of standard shape and dimensions, corresponding to the shape plugs to connect to socket 10.
- the plug 25 represented by FIG. 1 is a standard three-pin plug 54, 55 and 56 intended to be engaged in the contact sockets mounted in the housing interior 11 opposite the openings 12, 13 and 14. This is for example a socket standardized for electrical distribution at 220-240 V.
- Auxiliary part 24 comprises a plate 57 provided with three holes 58 in which can engage pins 54 to 56 of plug 25, so that plate 57 can be applied against the body of the plug.
- the plate 57 On the side opposite the plug, the plate 57 carries a pin keying device 59 which, when the auxiliary part 24 is mounted on the plug 25, extends parallel to pins 54 to 56 and has approximately the same length.
- the auxiliary part 24, the cover 23, the movable part 16 and the cradle 17 are made of insulating material and are preferably made by molding.
- the thrust is symmetrical on the two inclined planes 40, so that the part 16 keeps its orientation and its rear hooks 46 engage between the two fingers of the cradle 17, then guide the part by sliding on the guide surfaces 39. It results that the lateral protuberances 21 of the movable part retract towards the front and allow pins 54 and 55 to penetrate into the openings 12 and 13 of the inner box 11 as shown in Figure 7.
- the ground pin 56 and the pin keying device 59 pass through the central opening 43 of the moving part to enter the openings 14 and 15 of the inner box 11. The electrical contact can be established between pins 54 to 56 of plug 25 and the corresponding sockets of this interior box 11.
- the moving part 16 When the plug is removed, the moving part 16 is released, so that the springs 18 bring it back to its original position by movements opposite to arrows A and B.
- the inclined surface 48 of the lug 47 is used to pass the lug under the front edge 51 of opening 33. Then, the lug automatically engages in this opening to lock the moving part.
- the socket according to the invention has effective means of protection against a accidental electrical contact, for example if a child tries to introduce an object in one of the outlet openings.
