Definitions

  • the present invention relates to electrical outlets and more particularly the outlets.
  • Electrical outlets having an insulating housing, at least one receiving cavity for a pin of a plug to be connected to the socket and at least one automatically connected terminal for connecting the cell to at least one cable are already known.
  • power supply the terminal having a cable insertion opening in a predetermined direction as well as a seat and a flexible member.
  • the flexible member has an edge facing the seat and is adapted, on the one hand, to deform under the effect of a bias oriented along the predetermined direction in a direction of insertion whereby the cable, when is engaged in the terminal by the insertion opening, can be inserted between the seat and the edge, and, secondly, to retain the cable between the seat and the edge under the effect of a urging oriented in the predetermined direction in an extraction direction opposite to the direction of insertion unless the flexible member is deformed to move the edge of the seat.
  • the invention aims to provide an electrical outlet both simple and easy to connect to a cable while being powerful and reliable.
  • an electrical socket comprising an insulating housing, at least one receiving cavity for a predetermined pin and at least one automatically connected terminal for connecting said cell to at least one power cable, said terminal having an opening insertion of said cable in a predetermined direction and a seat and a flexible member, said flexible member having an edge facing said seat and being adapted, on the one hand, to deform under the effect of a biased stress along said direction in an insertion direction whereby said cable, when engaged in said terminal by said insertion opening, is insertable between said seat and said edge, and, on the other hand, retains the cable between said seat and said edge under the effect of a bias oriented along said direction in an extraction direction opposite to the direction insertion device unless said flexible member is deformed to move said edge away from said seat, characterized in that said terminal comprises a support member to which said seat belongs and a fixed member which carries said flexible member, said support member being movable relative to said fixed member of this terminal, and in that said cell has a fixed member and a member movable relative
  • said plug also comprising a connecting member of the movable member of the cell to the support member of the terminal adapted to drive said support member towards said flexible member during said movement whereby the cable is further gripped by said support member and said flexible member in the presence of said pin da ns said cell.
  • the drive of the support member of the terminal by the movable member of the cell passes the support member of a first position it occupies in the absence of the spindle at a second position that it occupies in the presence of the spindle.
  • the flexible member In the first position of the support member, the flexible member is not or only slightly constrained by the support member so that it is possible to introduce a cable between the support member and the flexible member without having to provide excessive forces while in the second position the support member generates through the cable further deflection of the flexible member which ensures, only when necessary (ie when the cable is connected at the terminal), an excellent electrical contact by reinforcing the contact pressure of the cable to the support member and the flexible member.
  • the cell has the particularity of having a fixed member and a movable member, the movable member being mechanically connected not to a movable contact but to a connection terminal of a cable d supply of the plug, this cable once introduced into the terminal remaining in permanent electrical contact with this terminal and this cell, a pin is present or not in the cell.
  • the socket 1 illustrated in Figures 1 to 3 comprises an insulating housing 2 of plastic, a cover 3 of the same material and three connection modules 4 (Figure 3).
  • connection module 4 is adapted to receive on one side an electric cable 5 and the other the corresponding pin 6 of a plug 7 ( Figure 13).
  • the insulating housing 2 has a first compartment 10 and a second compartment 11.
  • Each of the compartments has a generally parallelepipedal shape with the compartment 10 which is smaller and attached to one of the faces of the compartment 11, centered with respect to this face.
  • the first compartment communicates with the second through three rectangular windows 13 ( Figure 3).
  • connection module In the wall of the compartment 10 situated at the level of the face of this compartment opposite to that connected to the compartment 11, there are provided for each connection module two insertion ducts 18 of electric cables and an orifice 19 for the passage of a push button that includes each of the connection modules.
  • the compartment 11 is fully open at its opposite side to that connected to the compartment 10 except on its periphery where the opening is surrounded by a flange with a rectangular contour 20 adapted to cooperate by its shape with the shutter cover 3.
  • This cover 3 has three through holes 25 formed in a recessed wall 26 relative to the remainder of the cover and a polarizing rib 27.
  • the recess of the cover has a contour adapted to receive by cooperation of shape the portion of a corresponding card 7.
  • the plug 7 illustrated in FIG. 4 comprises an insulating housing 30, three pins 6 projecting from the housing 30 and a collar 31.
  • Each of the pins 6 is connected to an electrical conductor (not shown) coming out of the insulating housing 30 through the collar 31.
  • connection modules 4 will now be described using FIGS. 6 to 14.
  • Each connection module 4 comprises a rigid and fixed frame 40, a movable arm 41, a flexible spring blade 42, and an actuating push button 43 (FIG. 8).
  • the frame 40 comprises a cage 45 with a rectangular section and a wall 46.
  • the wall 46 is located in the extension of a wall 47 of the cage 45 opposite a wall 49 of this cage carrying the leaf spring 42 (FIG. ).
  • the cage 45 defines with the pusher 43 two openings 39 for insertion of electric cables.
  • the arm 41 has a first wall 50 (FIG. 11), one end of which is connected to the wall 47 by an elastically deformable U-shaped fold 53, a second wall 51, one end of which is connected transversely to the end of the wall 50 opposite to that attached to the fold 53 and a third wall 52, one end of which connects transversely to the end of the wall 51 opposite to that attached to the wall 50.
  • the walls 46 and 52 are facing each other and form a receiving cavity 54 of a pin 6 of the plug 7 while the wall 50 forms as will be seen hereinafter with the cage 45 and the leaf spring 42 a self-connecting terminal 55.
  • the walls 46 and 52 are slightly curved at their free end so that they form a guide flare 56.
  • the wall 50 and the wall 47 of the cage are opposite one on the other and substantially parallel to each other.
  • the flexible leaf spring 42 comprises a first straight section 60, two curved sections 61 and two straight sections 62 whose width is substantially equal to half the width of the straight section 60.
  • each curved section 61 is connected to one end of the straight section 60 while the opposite end of the section 61 is connected to one end of a corresponding straight section 62 forming a bent elbow on the opposite side to the straight section 60.
  • Each curved section 61 (respectively each straight section 62) is separated from the neighboring curved section (or the adjacent straight section, respectively) by a slot 63.
  • the push button 43 comprises a support button 70, a central partition 71 and two actuating fingers 72.
  • the actuating fingers are arranged on each side of the partition 71, the thickness of this partition being slightly smaller than the width of the slot 63.
  • the assembly of a module 4 is performed by placing the spring blade 42 in the cage 45 so that the end edges 64 of the sections 62 are facing the surface 57 of the wall 50 of the mobile arm 41 facing wall 49 (FIG. 11).
  • the spring blade 42 is held integral with the cage 45 by being pressed against the wall 49 opposite the wall 47 of the cage 45 via the tabs 44 formed in the cage 45 and bent against the spring blade at the notches 65 .
  • the pusher 43 is then also partially introduced into the cage with the partition 71 which is housed between the sections 62 and the sections 61 in the slot 63, each of the fingers 72 being placed in the vicinity of the corresponding section 62.
  • Each of the modules 4 is then placed in the insulating casing 2 with its automatic connection terminal 55 which is located in the compartment 10 and its cell 54 in the compartment 11 (FIG. 3).
  • the first operation is to penetrate the rigid cable 5 through the conduit 18 of the housing 2 in which it must be inserted until the stripped end 8 of the cable passes through the corresponding insertion opening 39 of the module 4 and come to bear against the corresponding section 62 to separate the end edge 64 of this section of the surface 57 of the support wall 50 to allow the end 8 to pass between this edge and this wall.
  • the driving movement of the cable may continue until the end of this cable abuts against the surface 38 of the wall 51 facing the spring blade 42.
  • the inner surface 57 of the support wall 50 thus forms a seat for the cable 5 against which it is held by the spring blade 42 which plates it against this surface. If this cable once installed in the terminal tends to be removed from the block, that is to say if it is subjected to a force directed in the direction opposite to the direction of insertion, this cable will tend to carry with it the section 62, which will bend and thus wedge against the wall 50, which will prohibit the removal of this element.
  • the operator presses the button 70 of the push button 43 towards the spring blade 42 so as to move this button to press the actuating finger 72 against the corresponding section 62 in order to constrain this section, the end edge 64 away from the seat 57 to release the cable and thus to extract it from the terminal.
  • the pins 6 pass through the orifices 25 of the cover 3 and penetrate into the compartment 11 of the insulating housing.
  • Each pin 6 penetrating into its corresponding cell causes a deformation thereof, the movable wall 52 tending to deviate from the fixed wall 46 of the cell belonging to the frame 40 to allow the pin to enter it .
  • the displacement of the wall 52 causes, via the connecting wall 51, the deformation of the fold 53 and the displacement of the bearing wall 50 towards the leaf spring 42.
  • the spring blade 42 and the wall 50 are thus judiciously arranged relative to one another to allow, on the one hand, the insertion of a cable with a non-zero but reduced force between this blade and this wall (that is to say only sufficient to prevent the removal of the cable by driving the spring blade to be arched) and to ensure, on the other hand, once the pin introduced in the cell, an optimal electrical contact by causing an additional deflection of the blade spring.
  • the reinforced electrical contact thus significantly minimizes the risk of heating in the socket during the passage of the current.
  • the mobile part of the cell is not a wall of this cell but for example a finger of conductive material or not connected by a connecting mechanism to the bearing wall of the terminal.
  • the push button is replaced by an actuating lever mounted to rotate.
  • the fixed members of the cell and the terminal do not belong to the same frame and are separated from one another.
