  • grounding contact elements in the form of a protruding pin on the front face of their housing or in the form of clamps extending diametrically inside the receptacles. edges of said front face.
  • these sockets with additional means providing a locking device shutter, this means being operable via a complementary device fitted to the plug and can be used keyed.
  • the polarizer which has a length greater than that of the male pins performs an actuation of the additional locking means in the direction of an unlocking of the closure device, which can then be moved in the direction of a releasing the passage for the male pins towards the female contact means.
  • the present invention aims to overcome these disadvantages by providing a socket provided with a safety device and provided with a complementary safety means preventing access to the live parts of the female element.
  • the socket which is essentially constituted by a housing enclosing a female electrical connection block, by a closure plate provided with electrical connection pin plug holes of a plug, these orifices being arranged above female plugs constituting said female electrical connection block and by a safety device, extending between the closure plate and the female electrical connection block and formed by a rotary or sliding shutter, is characterized in that it is further provided with a complementary safety means, extending between the closure plate and the female electrical connection block, in the axis of the passage orifices. of the closing plate and the sockets and being totally mechanically independent of the safety device, this complementary means being operable by means of a keying device fitted to the plug or an intermediate piece that can be secured to said plug and through the closing plate.
  • FIG. 1 of the accompanying drawings shows a socket, which consists essentially of a housing 1 enclosing a female electrical connection block 2, by a closure plate 3 provided with plugs of electrical connection pins of a plug male (not shown), these holes being disposed above female plugs constituting said female electrical connection block 2 and by a safety device 5, extending between the closure plate and the female electrical connection block and formed by a rotating or sliding shutter.
  • this socket 1 is further provided with complementary safety means 6 extending between the closure plate 3 and the female electrical connection block 2, in the axis of the orifices. passing the closing plate and the sockets of said female electrical connection block 2 and being completely mechanically independent of the safety device 5, this complementary means 6 being operable via a coding device 7 fitted to the plug or an intermediate piece 8 that can be secured to said plug and through the closure plate 3.
  • the intermediate piece 8 carrying the keying device 7 is shown in its insertion position in the closure plate 3, in which it passes through said closure plate 3 to cooperate with the complementary safety means 6.
  • the safety device 5 extending between the closure plate 3 and the female electrical connection block 2 is constituted, for example, in the form of a rotary shutter comprising two wings in the form of propeller blades, at least one of which is loaded by a return spring 9 into position and by a casing 10 for accommodating and guiding said shutter 5 and the return spring 9, this casing 10 being provided with two orifices 10 'for passage of the electrical connection pins of the plug.
  • the security device 5 may also be in the form of a sliding shutter of known type and which does not require a detailed description. Indeed, in the case of a sliding shutter, the passage holes of the male connection pins are covered by two identical branches of a slide guided in displacement in a housing and loaded by a return spring.
  • the safety device 5 which is of known type, has a mounting of the rotary shutter or the slider such that its operation is made impossible if the two wings of the propeller or the slider are not actuated simultaneously by the two connection pins of a plug.
  • the complementary safety means 6 is in the form of at least one slider extending above or below at least one wing of the rotary or sliding shutter forming the security 5 ( Figures 1 to 3).
  • This slide forming the complementary safety means 6 has an upper surface facing a passage hole of a connecting pin of a plug of the closing plate 3 of the housing 1, flat.
  • the slider 3 prevents, in its operating position, any contact between the corresponding male connection pin and the corresponding socket of the female electrical connection block 2.
  • the prevention of this contact is achieved both in the position shown in FIGS. FIGS. 1 to 3, in which the slider forming the means 6 extends above the safety device 5 only in a position, not shown, in which the device forming the means 6 would extend into below the safety device 5 and above the female electrical connection block 2.
  • the slide forming the complementary safety means 6 has, at its upper surface facing the passage of a connecting pin of a plug of the plate closure 3 of the housing 1, a recess 11 intended to cooperate with the corresponding male pin of the plug in the direction of holding the slide between the corresponding orifice of the closure plate 3 of the housing 1 and the safety device 5 or the corresponding socket of the female connection means 2 of the socket.
  • the slider forming the complementary safety means 6 comprises a means 12 for automatically returning to the covering position of the opening orifice of the closure plate 3 of the housing 1 of the socket or the corresponding female plug of the female connection means 2.
  • the return means 12 may be formed as a return spring supported on a guide means of the slider forming the means 6 and said slider.
  • the slide forming the complementary safety means 6 comprises a displacement control means 13 cooperating with the coding device 7 fitted to the plug or the intermediate piece 8.
  • This means 13 of displacement control may advantageously be in the form of an inclined plane extending inside the body of the slide forming the complementary safety means 6, in a direction opposite to that of covering the passage of the corresponding male connection pin resulting from the load exerted by the return means 12 on the slider.
  • the return means 12 is housed directly in the slider 6 and rests on a portion of the guide element of said slider, this portion passing through said slider by a corresponding longitudinal groove.
  • the slider forming the complementary safety means 6 can advantageously be housed, as shown in FIGS. 1 to 3 of the accompanying drawings, directly in a guide space 10 "of the housing 10 of the device 5, a wall of this space passing through a longitudinal groove of the slider 6 to form a support for the return means 12.
  • the housing 10 of the safety device 5, which serves simultaneously to housing to the complementary safety means 6, can be directly mounted between the housing 1 for receiving the female electrical connection block 2 and the closing plate 3 of said housing 1.
  • the complementary safety means in the form of two sliders arranged parallel above or below the wings of the rotating or sliding shutter forming the safety device, under the passage holes of the male pins of the closure plate 3 of the housing 1 or above the female sockets forming the female connection block 2 of the socket.
  • Such an embodiment of the additional safety means in the form of two sliders, each assigned to a wing of the shutter forming the safety device further improves the safety of the whole of the grip against unwanted penetration via a rigid conductor or a rigid filamentary element such as a screwdriver and thus prevents access to the socket with the risk of electrocution resulting.
  • the two slides forming the complementary safety means are arranged to move in opposite directions, contrary to the direction of the wings of the rotary shutter and can advantageously being connected by means of a linkage moving them in opposition, when one of said sliders is actuated via the foolproofing means 7.
  • the two slides of the complementary security means move in the same direction and can be interconnected by means of a rigid connection device, each slider being loaded by a return spring, or the rigid connecting device alone being loaded by a return spring.
  • a complementary safety means comprising two sliders
  • the complementary safety means may also be formed in the form of at least one pivoting or revolving covering element, extending above or below a wing of the rotary or sliding shutter forming the safety device 5 and articulated on the closing plate 3 of the housing 1 or mounted in a specific guide housing, this element being actuated by means of the foolproofing device 7 of the plug or the intermediate piece 8 fitted to said plug and being held in the operating position, or recalled in this position via an elastically deformable return means, such as a spring or the like.
  • the complementary safety means in the form of a rotary element provided with two simultaneous covering lugs of the wings of the rotary or sliding shutter forming the safety device 5.
  • the rotary element forming the complementary safety means may advantageously be actuated in the same direction as a rotary shutter forming the safety devices 5.
