Definitions

• the invention relates to a sealed electrical connection element, constituting, for example, the base of a socket, or the mobile socket of an extension or a connector.
• a known connection element for the aforementioned applications is generally provided with electrical contacts mounted in an insulating block, and distributed peripherally and which are provided to cooperate with the corresponding contact pins of a plug, after coupling of said plug with said element to during at least a first translational movement followed by a rotation and a second translation, while a rotating safety disc is arranged above the insulating block of the connection element and comprises peripheral openings whose the number and the positioning are chosen so as, on the one hand, to hide at rest the peripheral contacts of the connection element and, on the other hand, to be superimposed on them after the rotation of the disk driven by the pins of the plug which have been introduced into said openings of the disk during the first translational movement.
• they In order to ensure the sealing at rest of such elements, they generally comprise a pivoting lid and lockable on a housing in which are disposed the insulating block and the contacts, said cover being folded sealingly on said housing in the rest position .
• connection element of the aforementioned general type further comprising sealing pads which are arranged under the security disk in equal numbers and arranged in the same way as the peripheral openings of the latter so as to sealingly close said openings in the rest position under the effect of elastic means, said sealing pads can be released from said peripheral openings by the pins of the plug.
• the sealing pads are arranged in the insulating block provided with the contacts.
• connection element of the aforementioned type provided with sealing pads, but which is particularly remarkable in that the sealing pads are arranged on a sealing disk which is arranged under the safety disk, which further comprises peripheral openings at least in equal numbers and arranged in the same manner as the peripheral openings of the safety disk, while being offset angularly relative to said sealing pads, and which is fixedly mounted in rotation and movable in translation against elastic means urging it towards the safety disc, to ensure a rest position in which the sealing studs seal said peripheral openings of the safety disc, while the sealing disc can be discarded from the safety disc by the pins of the plug during the first translational movement of the so that the sealing studs are released openings of the safety disc which can be rotated by said pins, which can then come into the connection position through the peripheral openings of the sealing disc, the latter taking up its sealing position during the uncoupling of the plug and said element, under the effect of said elastic means which it is provided.
• the safety disc is provided with a central extension on which is mounted movably in translation the sealing disc provided for this purpose with a central opening of shape conjugate to that of the extension.
• the resilient means that urge the sealing disc towards the safety disc consist of springs disposed substantially under each of said pads.
• the safety disc and the insulating block are provided with means for sealing the safety disc at its periphery, said means for sealing being for example constituted by a peripheral groove which is formed in a sleeve surrounding the insulating block of the element and in which the safety disc rotates, and by an annular seal housed in said groove of the sleeve.
• each sealing pad is constituted by a nipple of corresponding shape to the opening of the safety disc to be sealed and an annular seal disposed at its base and which is applied in the closed position under the security disk.
• FIG. 1 shows, by way of example, a connection element according to the invention, seen at the end and in the rest position,
• FIG. 2 is a section along II-II of FIG. 1,
• FIG. 3 corresponds to the section of Figure 2 further showing a connection plug for mating with the connection element and after introduction of said plug by a first translational movement
• FIG. 4 is a view corresponding to FIG. 1 after a rotational movement of the safety disk, positioning the latter in the connection position,
• FIG. 5 is a section along the line V-V of Figure 4 with further representation of a plug as in Figure 3.
• connection element 1 of the socket base type, or mobile socket of an extension or a connector show a connection element 1 of the socket base type, or mobile socket of an extension or a connector.
• the element 1 is intended to mate with a plug schematically in 2 in Figures 3 and 5.
• the connection element 1 comprises several contacts and in the example shown, in addition to a ground contact 3a disposed in the center, it is provided with four peripheral contacts 3b-3e (FIGS. 4 and 5) distributed in the example shown, on a single circumference and of which only 3c is visible in Figure 5, said peripheral contacts constituting for example a neutral contact and three phase contacts.
• the contacts shown are so-called end contacts arranged in housings of an insulating block 4 and biased by springs also arranged in said insulating block 4.
• the connection element 1 is intended as already said, at s to couple with a plug such as the plug 2 schematically in Figures 3 and 5, which is provided with as many contact pins (such as the central pin 5a and the peripheral pins 5b and 5c) that the element 1 comprises him - even contacts.
• connection element 1 further comprises, in a conventional manner, above the insulating block 4, a rotary safety disc 6 provided with openings 7a-7e whose number and positioning are chosen so as, on the one hand, to hide at rest the peripheral contacts 3b-3e of the connection element 1 (position of Figures 1 to 3) and, secondly, to be superimposed thereto after rotation of the safety disc (position of Figures 4 and 5).
• the plug 2 and the connecting element 1 are indeed provided with conjugate means to ensure their coupling consisting in introducing in a first translational movement the pins 5a-5c of said plug in the corresponding openings 7a-7c of the safety disc 6 , then to rotate the latter to align the peripheral pins of the plug with the peripheral contacts of the connection element (FIG. 5) and to terminate the coupling and thus the connection by a last translational movement (not shown) until a locking of the connection element 1 and the plug 2 by appropriate means.
• the invention recommends that a sealing disk 8 be arranged under the safety disc.
• the sealing disc 8 has as many sealing pads 9b-9e and openings such as 16c ( Figure 5) that the security disc has peripheral openings 7b-7e and which are positioned in the same manner with a angular offset provided between said pads and said openings of the sealing disc.
• the sealing disk 8 is mounted fixed in rotation, but mobile in translation, while it is biased towards the safety disk 6 by elastic means and in this case by springs such as 10 ( Figures 2 and 3) so that at rest, the pads 9b-9e of the sealing disc 8 come to close the corresponding openings of the safety disc 6, as shown in Figures 1 and 2.
• the pads 9b-9e which are in the form of nipples of a shape corresponding to the openings to be closed, are provided at their base with annular seals such as 11b and 11c (FIGS. 2, 3 and 5) which remain disposed under the security disc 6 and in which they come to apply in the closed position.
• the safety disk is rotatably mounted in a sheath 12 surrounding the insulating block 4 and it also cooperates with a peripheral seal 13 housed in a suitable groove of said sheath 12.
• the safety disc 6 and the sealing disc 8 are assembled by a sleeve 14 around which rotates the safety disc 6.
• the sealing disc 8 is mounted movable in translation on a central tubular extension 15 of the safety disc 6, by means of a central opening which it is provided and whose shape is conjugate to that of said extension of the safety disc. In this way, it is understood that at rest, the sealing disc 8 provides, as already said, a seal vis-à-vis the peripheral contacts 3b-3e of the connection element ( Figures 1 and 2).
• the first translational movement of the plug 2 makes it possible to push the sealing pads 9b-9e against the force of the springs 10.
