Definitions

  • the invention relates to a socket for electrical connection with a plug or the like, and constituting the base of an electrical outlet or the mobile socket of an extension cable or connector.
  • a socket outlet provided of several contacts arranged in housings arranged in a support according to a circumference, one of them being however central, while at least one safety disc made of insulating material pivotally mounted on the contact support coaxially to the contact circumference, has openings intended to be crossed by the plug contacts and is arranged to be rotated by the plug to move from an initial position in which the housings of the circumferential contacts are at less largely closed at a connection position at the end of rotation which uncovers at least some of said contact housings.
  • the devices mentioned above relate more specifically socket outlets but we can of course generalize to other electrical connection systems, as mentioned above, such as a mobile socket of an electrical connector (intended for mate with the connector base including the contact members are generally similar to those of a plug) or the mobile socket an extension (designed to mate with a plug), hence the more general expression used.
  • It is generally a multiple contact socket intended to be coupled with a plug or similar fitted with contacts under pin shape.
  • the shutter is mounted mobile radially in the support, while the combined drive means are in the form of a planned training pin under the safety disk and an oblique groove in the shutter so that the rotation of the disc causes a translational radial movement of the shutter and allows passing from one closed position of the central housing to a release position and reciprocally.
  • the oblique groove has at least one of its ends, a small extension in the direction of the rotary movement to tolerate a small play in rotation of the safety disc, without action on the translational movement of the shutter.
  • the shutter is movably mounted in a groove radial of the contact support which opens above or into the upper part of the central contact housing.
  • the shutter is presented in the form of a bar mounted freely in rotation at one of its ends, near the peripheral circumference of the support of contacts, while it has at its other end a groove or light, for example axial and oblong, intended to cooperate with a lug fitted under the safety disk, said lug and said light constituting the shutter drive means so such that a rotation of the safety disc causes a rotation of the shutter in the form of bar and allows to pass from a position closing the central housing by the middle part of the bar, to a release position and vice versa and according to a particularity, the middle part of the bar-shaped shutter is present a bulge.
  • the socket outlet shown includes so known an insulating support 1 provided in particular with housings such as 2 for ejection springs intended to load an ejection washer and locking 3, and several housings in the form of wells 4a to 4e, of which here four, 4a to 4d, are arranged substantially on one circumference and another 4th centrally.
  • the contacts provided in the circumferential housings are, for example, phase and neutral contacts, while housing central is more particularly intended to receive the contact earthen.
  • the base shown further comprises a safety disk 5 and an additional disc 6, called a coding disc, between which is provided here a coding pawl 7.
  • the discs 5 and 6 are mounted on the support 1 by means, by example, of a ferrule 8.
  • the discs 5 and 6 are provided with lights 10a to 10d and respectively 11a to 11d corresponding to the locations of the housings 4a to 4d of the support 1 in order to be able, by rotation of the discs, to juxtapose said lights with said housings.
  • discs 5 and 6 hide and protect in the rest position the housings 4a to 4d and therefore the contacts they contain, as shown in Figure 2.
  • the additional coding disc 6 is not compulsory and corresponds to an embodiment which allows in particular by locking in various relative positions with the safety disk 5 using the ratchet 7, use the same base for several types of current, as already said in connection with patent FR 2 680 608 already cited.
  • discs 5 and 6 have a central opening respectively 10th and 11th for the passage of the contact plug earth.
  • the shutter 9, as shown in Figure 1, is mounted sliding radially in a corresponding groove 12 of the support 1 which opens into or above the 4th housing.
  • said shutter has a projection 13 intended to slide in a corresponding groove 14 of support 1.
  • said shutter is provided with a rounded protuberance 15 and an oblique groove or slot 16.
  • the shutter 9 can pass from a position in which it releases the 4th housing or on the contrary, it closes it.
  • the disc 5 has a lug 17 which is not visible in Figures 1 and 2 but visible in Figures 3 to 5, intended for come into the groove 16 of the shutter.
  • the combined effect of the lug 17 of the disc 5 and the oblique groove 16 of the shutter is similar to a cam effect which transforms the rotary movement of translating moving discs of said shutter.
  • the groove 16 of the shutter 9 present at one of its ends (but it could have another, symmetrical from the first to the other end), an extension 18 in the direction of the rotary movement for tolerate a small play with the rotation of the safety disk 5, without action on the translational movement of said shutter 9 and thus avoid an untimely movement of it for small movements of the discs.
  • Figure 3 and its enlarged detail of Figure 4 shows well a rest position in which the shutter 9 closes the entry of the 4th slot of support 1.
  • FIGS 6 and 7 show another embodiment of which elements of the same nature as those previously described carry the same references but with an accent.
  • the shutter 9 ' is presented under the shape of a bar freely articulated in rotation to one of its ends 19, while its other end has a oblong groove or slot 16 'in the axis of the bar, intended for cooperate with a lug of the disc 5 ', the position of which has been shown in 17 'on the latter (position also shown schematically in the light 16 'of the shutter).
  • the oblong light 16 ′ could be provided on the side of the articulation end 19.
  • the middle part of the shutter 9 ' has a protuberance or 15 'rounded bulge intended to close off the central housing 4th of support 1 ', as shown in Figure 6, the openings 10'a to 10'e and 11'a to 11'e of the disks 5 and 6 respectively not being, for this position, in alignment with the housings 4'a to 4'd of the support 1 '.
  • the support 1 or 1 ′ can be that a socket outlet, but also that of a mobile outlet designed to connect either to a connector socket or to a extension plug, hence the general expression used, as already says, taken, while also generalizing the plug which can therefore constitute the base of a connector.
