Definitions
- Automatic connection terminal comprising two contact zones and associated electrical equipment mechanism
- the present invention relates to an automatic connection terminal for an electrical equipment mechanism.
- It also relates to an electrical equipment mechanism provided with such an automatic connection terminal.
- connection terminals have, for the most part, a corridor for inserting and guiding the conductive wire into the connection terminal, which extends over the entire length of the bare part of the conductive wire. This insertion and guiding channel ensures good maintenance of the conductive thread. This is of particular interest, for example, when the connection terminal is moved or manipulated after insertion of the conductive wire into the connection terminal.
- connection terminals have a large size, in particular linked to the presence of the passage for inserting and guiding the conductive wire.
- connection terminals Furthermore, in these already known connection terminals, the conductive wire is in contact with the metal element of the connection terminal along the insertion channel, over a contact zone which is not precisely delimited.
- the present invention proposes an automatic connection terminal allowing, on the one hand, a reduction in the size of the connection terminal and, on the other hand, the control of the contact points between the conductive element of the terminal and the conductive wire inserted in the connection terminal.
- an automatic connection terminal comprising a metal strip comprising two parts connected by a bridge and a leaf spring which extends parallel to a first of said two parts of the metal strip and in line with the bridge, an opening being arranged at the level of the bridge so as to allow a conductive wire to pass through an insertion site, part of which is located between the leaf spring and a second of said two parts of the metal strip, said second part of the metal strip forming a boss at the top of which there is a first zone of electrical contact between the metal strip and the conductive wire against which said leaf spring is adapted to clamp said conductive wire when the latter is introduced through said opening in the connection terminal, in which said metal strip forms, facing said second part of the metal strip, a wall which extends at least partially ment in the place of insertion of the conductive thread, so as to provide a second electrical contact area between the metal strip and the conductive wire, distinct from the first contact area.
- connection terminal in the connection terminal according to the invention, the two distinct contact zones are located over a limited area.
- the stripped metal core of the conductive wire inserted in the automatic terminal necessarily comes into electrical contact, on the one hand, with the first contact zone against which it is clamped by the spring blade, and, on the other hand, with the second contact zone which belongs to the wall of the metal strip which extends at least partially into the place of insertion of the conductive wire.
- a quality electrical connection is thus ensured between the conductive wire and the metal strip of the connection terminal.
- connection terminal in the connection terminal according to the invention, the two contact zones of the metal strip provide two current flow paths in the connection terminal, which limits overall heating of the latter during the passage of a Electric power.
- connection terminal with, on the one hand, the metal strip provided with two parts connected by a bridge and, on the other hand, the leaf spring which extends parallel to a first of said two parts of the metal strip and in line with the bridge in the rest position, makes it possible to limit the size of this terminal.
- connection terminal according to the invention thus ensures the quality of the electrical connection while having a limited bulk.
- said metal strip has an end portion to which said wall is attached;
- said metal strip has a main part, generally elongated along a longitudinal axis, which integrates the first and second parts connected by the bridge, and said end part has an angled shape, one side of which forms an acute angle with the axis longitudinal of said main part;
- said wall extends opposite said boss, in line with it or in a zone close to the zone located in line with said boss;
- said wall is movable between a rest position and an active position, the hinge permanently biasing said wall into the rest position, and, in the rest position, said wall extends at least partially into the place of insertion of the conductive wire while, in the active position, said wall moves away from said rest position to allow the conductive wire to pass while exerting on it a stress in the direction of the second part of said metal strip;
- - Said metal strip comprises, at one of its ends, a socket for receiving a pin of an electrical plug
- each of said walls formed by said metal strip is connected to a partition which separates the places of insertion of the two conducting wires;
- connection terminal there is provided, at the part of the edge of each opening closest to the other opening, a tab which extends substantially perpendicularly to said metal strip, towards the inside of the connection terminal.
- the invention also relates to an electrical equipment mechanism comprising at least one automatic connection terminal as described previously.
- the invention relates to such an electrical equipment mechanism comprising a base provided with a pair of insertion ducts giving access to the two openings of said connection terminal, each insertion duct comprising, on an internal face, a rib which extends towards the inside of the insertion duct, the rib of each insertion duct and the tongue of the opening associated with this insertion duct being arranged on either side of the axis longitudinal of this duct and in the plane containing the two longitudinal axes of the two insertion ducts.

- the connection element can also be a reception cell 201 (figures 8 to 14), adapted to receive a connection pin of an electrical plug of any electrical device.
- connection terminal 100; 200; 300 comprises a conductive body formed by a metal strip 110; 210; 310.

- the metal strip 110; 210; 310 forming the conductive body has a generally elongated shape, folded around several mutually parallel transverse axes ( Figures 1, 2, 8, 9, 15,16 and 22).
- the metal strip 110; 210; 310 is delimited by two main faces 110A, 110B; 210A, 210B; 310A, 310B (FIGS. 7, 14, 21 and 22) opposed parallel.
- a rear main face 110A; 210A; 310A is oriented towards the installer: this is the face on the side of which the stripped end of the conductive wire 1 is introduced into the connection terminal 100; 200; 300.
- the other main front face 110B; 210B, 310B corresponds to the face on the side of which the stripped end of the conductive wire 1 emerges inside the connection terminal 100; 200; 300.
- the main faces 110A, 110B; 210A, 210B; 310A, 310B are connected by longitudinal edges HOC; 210C; 310C and 110D end edges; 210D; 310D (figures 1, 8, 15 and 22).
- the metal strip 110; 210; 310 comprises a main part PPI; PP2; PP3 which extends globally along a longitudinal axis XI; X2; X3 (figures 7, 14, 21 and 22).
- This main part PP1; PP2; PP3 of metal strip 110; 210; 310 comprises a first and a second part 111, 112; 211, 212; 311, 312 of the metal strip 110; 210; 310 connected by a bridge 113; 213; 313 (see in particular figures 2, 7, 9, 14, 16,21 and 22).
- the metal strip 110; 210; 310 further comprises two end portions PCI, PLI; PC2, PL2; PC3, PL3 located on either side of the main part PPI; PP2; PP3.
- one of the two end parts forms a PCI connection part; PC2; PC3 which accommodates said connection element of the connection terminal 100; 200; 300 and the other end portion is a PLI free end portion; PL2; PL3.
- the first 111; 211; 311 of the two parts 111, 112; 211; 212; 311, 312 of the main part PP1; PP2; PP3 of metal strip 110; 210; 310 is substantially planar and extends along a median plane comprising the longitudinal axis XI; X2; X3.
- Bridge 113; 213; 313 has an at least partially curved shape. It rises from the first part 111; 211; 311 of the PPI main part; PP2; PP3 of the metal strip, on a rear side of the median plane of this first part 111; 211; 311, then joins the second part 112; 212; 312 of the PPI main part; PP2; PP3 of the metal strip at the level of the median plane or at the front of this median plane.
- bridge 113; 213; 313 forms a first bump, the concavity of which faces the inside of the connection terminal 110; 210; 310. It joins the second part 112; 212; 312 of the PPI main part; PP2; PP3 of the metal strip at the level of a second bump, the concavity of which faces away from the first bump and against which electrical contact is intended to be established between the stripped core of the electrical conductor wire 1 and the strip metallic 110; 210; 310, as described in more detail below.
- the profile of the metal strip 110; 210; 310 thus draws a generally S-shape at the level of the bridge 113; 213; 313 (figures 2, 9, 16 and 22).
- An opening 114; 214; 314 is made in the metal strip 110; 210; 310 at deck 113; 213; 313 so as to allow the stripped end of the conductive wire 1 to pass (see in particular FIGS. 3, 10, 17, 22 and 24).

- connection terminal 100; 200; 300 further comprises a leaf spring 120; 220; 320 (not shown in Figure 22).
- This spring blade 120; 220; 320 is deformable between two configurations: a rest configuration, in which it is unconstrained and therefore undeformed (figures 1, 2, 3, 8, 9, 10, 15, 16 and 17), and a tightening configuration, in which it is elastically deformed by the passage of the stripped end of each conductive wire 1 (FIGS. 4 to 7, 11 to 14 and 18 to 21).
- the leaf spring 120; 220; 320 In its clamping configuration, the leaf spring 120; 220; 320 is permanently recalled to its idle configuration. In doing so, it clamps the stripped end of the conductive wire 1 against the front face 110B; 210B; 310B of the metal strip 110; 210; 310 (figures 4 to 7, 11 to 14 and 18 to 21).

- One of the transverse end edges 121A; 221A; 321A defines a two-tooth fork and the other transverse end edge 126A; 226A; 326A is right.
- the leaf spring 120; 220; 320 includes a fixed portion 121; 221; 321 which extends against the front face 110B; 210B; 310B of the metal strip 110; 210; 310, at the level of the first part 111; 211; 311 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310, and a movable portion 126; 226; 326 which extends the fixed portion 121; 221; 321 and extends mainly to the right of bridge 113; 213; 313.
- This spring blade 120; 220; 320 thus extends parallel to the first part 111; 211; 311 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310 and to the right of bridge 113; 213; 313 ( Figures 1, 2, 8, 9, 15, and 16), along the longitudinal axis XI; X2; X3 of metal strip.
- the fixed portion 121; 221, 321 of the leaf spring 120, 220, 320 is held in place against the first part 111; 211; 311 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310 by two side tabs 115; 215; 315 of connection terminal 100; 200; 300 (FIGS. 1 to 5, 7 and 8 to 22) which extend from the longitudinal edges HOC; 210C; 310C of the metal strip 110; 210; 310, at the level of the first part 111; 211; 311 of its main part PP1; PP2; PP3.
- These side legs 115; 215; 315 are folded towards each other opposite said metal strip, on the leaf spring 120; 220; 320.
- the spring blade 120; 220; 320 can for example be riveted to these side tabs 115; 215; 315, or may include openings suitable for hooking around the pins of these side tabs 115; 215; 315.
- the movable portion 126; 226; 326 of leaf spring 120; 220; 320 is located at the free end of the leaf spring 120; 220; 320. It is adapted to be bent by inserting the stripped core of the conductive wire 1 into the connection terminal.
- the movable portion 126; 226; 326 of leaf spring 120; 220; 320 is for example connected to the fixed portion 121; 221; 321 of leaf spring 120; 220; 320 by an elastic hinge 127; 227; 327 ( Figures 4, 11 and 18) which allows the deflection of this movable portion 126; 226; 326 while tending to bring it back to its resting position.
- the spring blade 120; 220; 320 In the rest configuration (FIGS. 1, 2, 3, 8, 9, 10, 15, 16, 17), the spring blade 120; 220; 320 is completely flat, the fixed and mobile portions being aligned.
- the transverse end edge 126A; 226A; 326A belonging to the mobile portion 126; 226; 326 of leaf spring 120; 220; 320 is then located very close to the second part 112; 212; 312 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310. It extends a few tenths of a millimeter from this second part 112; 212; 312 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310.
- the movable portion 126; 226; 326 flexes at the elastic hinge 127; 227; 327 so that it deviates from the metal strip 110; 210; 310 to allow the stripped core of conductive wire 1 to pass.

- each branch 123, 124; 223, 224; 323, 324 comprises a mobile part connected to a fixed part by a zone allowing the selective deformation of the mobile part of one of the two branches independently of the other branch when a single conductive wire is inserted into the openings 114; 214; 314 of the metal strip ( Figures 4, 11 and 18).
- each branch 123, 124; 223, 224; 323, 324 is connected to the fixed part of this branch by the elastic hinge 127; 227; 327.
- Each branch 123, 124; 223, 224; 323, 324 of the leaf spring 120; 220; 320 is thus adapted to clamp only one of the two conductive wires 1 inserted into the connection terminal.
- the movable portion 126; 226; 326 of leaf spring 120; 220; 320 is further provided with a central tab 125; 225; 325 guide ( Figures 1, 8 and 15).
- This central tab extends along the longitudinal axis of the leaf spring, projecting from the transverse end edge 126A; 226A; 326A of leaf spring 120; 220; 320.
- the central tongue 125; 225; 325 is separated by said longitudinal slot 122; 222; 322 in two parts each belonging to one of the branches of the leaf spring 120; 220; 320.
- the central tab 125; 225; 325 is accommodated in a groove 116; 216; 316 of the metal strip 110; 210; 310 (figures 1, 8 and 15).
- This central tongue forms a slider which slides in the groove to guide the leaf spring 120; 220; 320 when it passes from its rest configuration to its tightening configuration and vice versa.
- the groove 116; 216; 316 is a longitudinal groove, which extends in the middle of the metal strip 110; 210; 310, at part of the bridge 113; 213; 313 and the second part 112; 212; 312 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310.
- the spring blade material 120; 220; 320 has satisfactory rigidity characteristics to play the role of clamping the electric wire. It is not necessary for it to be made of a conductive material, which makes it possible to limit the quantity of conductive material used to manufacture the connection element according to the invention.
- the leaf spring is for example made of steel, in particular of stainless steel.
- Each opening 114; 214; 314 provided at the level of bridge 113; 213; 313 allows the stripped end of the conductive wire 1 to pass along the insertion axis 11; 12; 13 ( Figures 7, 14, 21) in an insertion site L1; L2; L3, part of which is located between the leaf spring 120; 220; 320 and the metal strip 110; 210; 310 (figures 4, 5, 7, 11, 12, 14, 18, 19 and 21).
- the insertion of the stripped core of the conductive wire is carried out in an insertion direction along the insertion axis 11; 12; 13, materialized by an arrow on the insertion axis of Figures 4, 5, 7, 11, 12, 14, 18, 19 and 21. This direction of insertion is oriented from the back to the front with the conventions of this description.
- each place of insertion L1; L2; L3 is partially located between one of the branches 123; 124; 223, 224; 323, 324 of the leaf spring 120; 220; 320 deformed in its clamping configuration and the second part 112; 212; 312 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310.
- boss 112A; 212A; 312A at the top of which is a first zone electrical contact ZI; Z2; Z3 between the metal strip 110; 210; 310 and the stripped end of the conductive wire 1, against which said spring blade 120; 220; 320 is adapted to clamp said stripped end of the conductive wire 1 when the latter is introduced into the connection terminal 100; 200; 300.
- This boss 112A; 212A; 312A corresponds to the second bump of the metal strip 110; 210; 310, which extends in the extension of the first bump formed by the bridge 113; 213, 313.
- Boss 112A; 212A; 312A is formed by bending the metal strip 110; 210; 310 around one of the transverse axes along which the metal strip is folded.
- the metal strip 110; 210; 310 moves away from said insertion site L1; L2; L3 of the conductive wire 1 on either side of said boss 112A; 212A; 312A. In other words, it moves away from said place of insertion L1; L2; L3 of conductive wire 1 on either side of the first contact zone.
- the contact zone ZI; Z2; Z3 has a precisely defined limited extent. This allows controlled, repeatable and reliable contact between the conductive wire and the connection terminal 100; 200; 300.
- said boss 112A; 212A; 312A is located close to the transverse end edge 126A; 226A; 326A of the movable portion 126; 226; 326 of leaf spring 120; 220; 320 in its rest position.
- said metal strip 110; 210; 310 form, facing said second part 112; 212; 312 of the PPI main part; PP2; PP3 of the metal strip, a wall 130; 230; 330 which extends at least partially into the L1 insertion site; L2; L3 of conductive thread 1, so as to provide a second zone Z3; Z4; Z5 of electrical contact between the metal strip 110; 210; 310 and the conductive wire 1, distinct from the first contact zone ZI; Z2; Z3 (figures 7, 14, 21 and 22).
- Said wall 130; 230; 330 extends opposite the boss 112A; 212A; 312A formed by the second part 112; 212; 312 of the connecting strip 110; 210; 310, in line with it or in a zone close to the zone located in line with said boss 112A; 212A; 312A.
- the position of said wall 130; 230; 330 is offset from the position of the boss 112A; 212A; 312A along the insertion axis 11; 12; 13 of the conductive wire 1, the offset being downstream along the direction of insertion of the conductive wire 1 into the connection terminal.
- connection terminal 100; 200; 300 being adapted to receive two conducting wires 1, the metal strip 110; 210; 310 forms two walls 130; 230; 330, each arranged to extend at least partially in one of the two insertion sites L1; L2; L3 of the conducting wires 1 (FIGS. 7, 14 and 21).
- each wall 130; 230; 330 is connected to the metal strip 110; 210; 310 by a resilient hinge portion 132; 232; 332 (figures 1, 3, 13, 15, 20 and 22).
- Said wall 130; 230; 330 is thus movable between a rest position and an active position, the elastic hinge 132; 232; 332 permanently recalling said wall 130; 230; 330 to its rest position.
- said wall 130; 230; 330 In the rest position, said wall 130; 230; 330 extends at least partially into the L1 insertion site; L2; L3 of the conductive wire 1 and in the active position, the wall 130; 230; 330 deviates from said rest position to allow the stripped core of the conductive wire 1 to pass while exerting on it a stress in the direction of the second part 112; 212; 312 of the PPI main part; PP2; PP3 of said metal strip.
- connection terminal 100; 200; 300 shown in the appended figures differ by the geometry of their conductive body, by the shape and the type of the connection element belonging to it.
- said wall 130; 230 is attached to one of the end portions of the metal strip 110; 210.
- connection terminal 100 In the first embodiment of the connection terminal 100 (figures 1 to 7 and 22), the wall 130 is attached to the PCI connection part of the metal strip 110.
- This PCI connection part has an angled shape, here at a right angle, one side of which constitutes a platform which overhangs said main part PP1 of the metal strip 110, and the other side connects said platform to the second part 112 of the main part PP1 of the metal strip 110.
- the platform forms an acute angle with the longitudinal axis XI of said main part PP1 of the metal strip 110.
- This platform includes an opening in which the ground pin 101 is crimped.
- the transverse end edge of the platform constitutes one of the end edges 110D of the metal strip 110 (FIGS. 1 and 22).
- the metal strip 110 comprises two drooping walls 131 which extend, from the two longitudinal edges HOC of the platform, perpendicular to the latter, in the direction of the main part PP1 of the metal strip 110 (FIGS. 1 to 3 and 22).
- Each drop wall 131 has an L-shape, a first branch of which is attached to the corresponding longitudinal edge HOC of the metal strip 110 and a second branch of which extends towards the second part 112 of the main part PP1 of the metal strip 110.
- the two drooping walls 131 are parallel to each other.
- There is provided at the end of each second branch a return directed towards the other second branch, that is to say towards the inside of the connection terminal 100. This return constitutes said wall 130.
- Each wall 130 is connected to the corresponding falling wall 131 by an elastic hinge
- Each elastic hinge 132 extends in a longitudinal direction inclined with respect to the axis of insertion 11 of the conductive wire 1.
- Each wall 130 also extends in an inclined manner with respect to the axis of insertion 11 of the conductive wire 1. It extends so as to approach the insertion axis 11 in the direction of insertion of the conductive wire 1 (FIG. 7), such that an edge of this wall 130 is extends in the place of insertion L1 of the conductive wire 1 in the absence of conductive wire inserted in the connection terminal.
- Each wall 130 is extended by a partition 133 (FIGS. 1 to 3) which extends so as to circumvent the place of insertion L1 of the conductive wire 1.
- the two partitions 133 attached to the two walls 130 thus extend back to back between the places of insertion L1 of the two conductive wires 1. They separate the places of insertion L1 of the two conductive wires 1 and prevent the stripped end of the conductive wire 1 inserted one of the places of insertion L1 from moving laterally to the other place of insertion L1 of the connection terminal 100.
- each opening 114 follows the profile of the metal strip 110 at the level of the corresponding part of the bridge 113.
- the opening 114 is thus delimited internally by the edge of the metal strip 110.
- the metal strip 110 comprises, at the level of each opening 114, a tongue 117 which extends from the edge of the metal strip 110, perpendicular to the part of the metal strip 110 surrounding the opening 114, towards the inside of the connection terminal 100.
- Each tab 117 extends from the part of the outline of the opening 114 closest to the longitudinal axis XI, that is to say the closest to the other opening 114.
- This tongue 117 forms a stop limiting the angular range authorized for the direction of insertion II of the conductive wire 1.
- the angle formed between the direction of insertion 11 and a plane perpendicular to said median plane passing through the longitudinal axis XI is by example limited to about 8 to 10 degrees.
- this second variant of the first embodiment of the connection terminal can advantageously be associated with an insulating base having a specific shape in order to limit even more effectively the angular range authorized for the direction of insertion Il of the common thread 1.
- connection terminal 200 In the second embodiment of the connection terminal 200 ( Figures 8 to 14), the wall 230 is attached to the free end part PL2 of the metal strip 210.
- This free end part PL2 of the metal strip 210 has a folded shape facing the second part 212 of the main part PP2 of the metal strip 210. It has an angled shape here having an L profile, with a first branch 218 connected to the second part 212 of the main part PP2 of the metal strip and a second branch 219 (FIGS. 8 and 9) extending at right angles from the first branch 218. These first and second branches 218, 219 have a reduced width compared to the width of the rest of the metal strip 210.
- the second branch 219 forms an acute angle with the longitudinal axis X2 of said main part PP2 of the metal strip 210.
- the transverse end edge of the second branch 219 constitutes one of the end edges 210D of the metal strip 210 (FIG. 8).
- two drooping walls 231 extend, from the two longitudinal edges 210C of the second branch 219 of the free end part PL2 of the metal strip 210, perpendicular to said second branch 219, in the direction of the main part PP2 of the metal strip 210 (FIGS. 9 and 10).
- Each wall 230 is connected to one of the drooping walls 231 by an elastic hinge 232 and extends outward from the connection terminal 200. There are therefore two walls 230 extending in opposite directions from the drooping walls 231.
- Each elastic hinge 232 extends in a direction inclined with respect to the axis of insertion 12 of the conductive wire 1, and each wall 230 also extends in an inclined manner with respect to the axis of insertion 12 of the conductive wire 1.
- Each wall 230 extends more precisely so as to approach the insertion axis 12 in the direction of insertion of the conductive wire 1 (FIG.
- the drooping walls 231 play the role of the partitions 133 of the first embodiment because they extend between the places L2 of insertion of the two conductive wires 1 that the connection terminal 200 is adapted to receive. They thus separate the L2 insertion sites of the two conductive wires and prevent the stripped end of the conductive wire 1 inserted into one of the L2 insertion sites from moving laterally towards the other L2 insertion site of the connection terminal. 200.
- connection part PC2 is attached to the first part 211 of the main part PP2 of the metal strip 110.
- This connection part PC2 comprises the connection element which has just been formed with the metal strip 210 and forms a connection cell 201.
- This connection element comprises two wings 203 rising facing each other, forwards, from a base 202 connected to the first part 211 of the main part PP2 of the metal strip 210.
- the two wings 203 each have a curved free end 203A (FIG. 11).
- These curved free ends 203A together form a clamp which delimits the reception cell. This extends along a receiving axis B (FIG. 11) which is substantially parallel to the axis of insertion 12 of the conductive wire 1.
- the wings 203 are hinged substantially around an axis perpendicular to the axis of reception B ( Figure 11).
- connection element 201 advantageously includes an additional element 240 (FIGS. 8 to 14), separate from the metal strip 210, in the shape of a jumper.
- This additional element 240 comprises a base wall 241 (FIGS. 10, 11 and 12) from which rise two side walls 242 inclined towards each other (FIGS. 10, 11 and 12).
- the side walls 242 are applied against the external faces of the flanges 203 of the connection element so as to grip them elastically.
- Each side wall 242 of the additional element 240 comprises a window which receives a relief provided projecting from the corresponding wing 203 of the connection element.
- connection terminal 300 In the third embodiment of the connection terminal 300 (FIGS. 15 to 21), said wall 330 is attached to the main part PP3 of the metal strip 220; 320.
- each lateral tab 331 is provided which extend from the longitudinal edges 310C of the metal strip 310, forwards, at the level of the second part 312 of its main part PP3.
- the free end of each lateral tab 331 is folded over so as to form a return which extends opposite the second part 312 of the main part PP3 of said metal strip 310.
- Said returns extend one towards the another and constitute said walls 330 (figure 16).
- Each wall 330 is connected to the corresponding side tab 331 by an elastic hinge 332.
- Each wall 330 extends in an inclined manner with respect to the axis of insertion 13 of the conductive wire 1. It extends so as to approach the axis of insertion 13 in the direction of insertion of the wire conductor 1 (FIG. 16), such that an edge of this wall 330 extends into the place of insertion L3 of the conductor wire 1 in the absence of a conductor wire inserted into the connection terminal.
- connection part PC3 of the connection terminal 300 comprises a platform 318 attached to the second part 312 of the main part PP3 of the metal strip 310.
- This platform 318 forms a slightly obtuse angle with the longitudinal axis X3 of the main part PP3 of the metal strip 310. It extends rearward, in a direction opposite to that of the side tabs 331.
- the platform 318 has an opening through which the contact block 301 is crimped.
- the leaf spring 120; 220; 320 of connection terminal 100; 200; 300 is in its rest configuration, completely flat, and each wall 130; 230; 330 is in its rest position, in which it partially extends into the L1 insertion site; L2; L3 of the corresponding lead wire.
- the stripped end of the conductive wire 1 pushes the movable portion 126; 226; 326 of leaf spring 120; 220; 320 which extends to the right of the opening 114; 214; 314 of the metal strip 110; 210; 310 corresponding.
- This mobile portion 126; 226; 326 deforms and goes into its clamping configuration: the conductive wire 1 passes between the leaf spring 120; 220; 320 and the metal strip 110; 210; 310 ( Figures 4, 5, 7, 11, 12, 14, 18, 19 and 21), in the L1 insertion site; L2; L3.
- the spring blade 120; 220; 320 clamps the stripped core of the conductive wire 1 against the first contact zone ZI; Z2; Z3 of the metal strip 110; 210; 310 located at the top of the boss 112A; 212A; 312A of the second part 112; 212. 312 of the main part PPI; PP2; PP3 of metal strip 110; 210; 310.
- the spring blade 120; 220; 320 does not block conductive wire 1.
- the mobile part of the leaf spring flexes and moves away from its rest position to allow conductive wire 1 to pass.
- the stripped core of the conductive wire 1 When the stripped core of the conductive wire 1 is pushed further along the insertion axis 11; 12; 13, it automatically comes into contact with the wall 130; 230; 330 of the metal strip 110; 210; 310, at the edge of this wall 130; 230; 330 which extends into the L1 insertion site; L2; L3 of the conductive thread 1.
- This edge of the wall 130; 230; 330 thus forms the second contact zone Z4; Z5; Z6 between conductive wire 1 and metal strip 110; 210; 310. Thanks to the inclination of the wall 130; 230; 330 with respect to the axis of insertion 11; 12; 13 of the conductive wire 1, the second contact zone Z4; Z5; Z6 has a limited range.
- the conductive thread 1 pushes the wall 130; 230; 330 which is adapted to pivot around the elastic hinge 132; 232; 332.
- it rubs on the second contact zone Z4; Z5; Z6 and passes it. This makes it possible to optimize the electrical performance of the connection terminal 100; 200; 300.
- the wall 130; 230; 330 deviates from its rest position and passes into an active position in which it allows the stripped core of the conductive wire 1 to pass into its place of insertion L1; L2; L3 and exerts on it a pressure generally in the direction of the second part 112; 212; 312 of the PPI main part; PP2; PP3 of metal strip 110; 210; 310.
- the stripped core of the conductive wire 1 completely inserted into the connection terminal 100; 200; 300 is thus in contact with the latter on two separate and distinct contact zones, which have a limited extent. It is in contact with the metal strip only on the two contact zones Z1, Z4; Z2, Z5; Z3, Z6. Furthermore, the extent of each of these two contact zones ZI; Z2; Z3, Z4; Z5; Z6 along the longitudinal axis XI; X2; X3 of metal strip 110; 210; 310 has a reduced size compared to the length of the stripped core of the conductive wire 1.
- the relative orientation of the wall 130; 230; 330 and the place of insertion Ll; 12; L3 of the conductive wire 1 is such that the force exerted by the wall 130; 230; 330 on the stripped end of the conductive wire 1 at the level of the second contact zone Z4; Z5; Z6 includes a component parallel to the force exerted by the leaf spring 120 on this bare end of the conductive wire 1 at the level of the first contact zone Z1; Z2; Z3.
- the wall 130; 230; 330 in its active position is substantially parallel to the movable portion 126; 226; 326 of leaf spring 120; 220; 320 in its clamping configuration ( Figures 7, 14 and 21).
- the pressure exerted by the wall 130; 230; 330 thus reinforces the action of the leaf spring 120; 220; 320 (shown schematically by arrows in Figures 7, 14 and 21).
- the maintenance of the conductive thread 1 is thus increased.
- the reliability of the electrical connection is increased.
- the contact force at the level of the first contact zone is increased, which contributes to the reduction of the contact resistance between the stripped end of the conductive wire 1 and the metal strip of the connection terminal.
- the heating of the connection terminal is therefore reduced.
- connection terminal 100; 200; 300 Furthermore, the presence of two contact zones between the stripped core of the conductive wire 1 and the metal strip 110; 210; 310 of connection terminal 100; 200; 300 generates a diversion of electrical current which is routed along two different paths. This derivation makes it possible to limit the overall heating of the connection terminal 100; 200; 300 during the passage of electric current.
- the two electrical current flow paths in the terminal also advantageously have a non-common part whose length is maximized so that the bypass limits heating.
- each opening of the terminal connection is provided with a tab extending inwardly of the connection terminal and located close to the longitudinal axis of this terminal, as is the case in the second variant of the first embodiment described above.
- connection terminals 100; 200; 300 on the insulating base of the fitting mechanism accommodating each terminal can be adapted to cooperate with the tongue provided at the level of the opening of the connection terminal in order to form a counter-stop for the conducting wire 1 when it is inserted into the connection terminal through the socket entry.
- FIGs 23 and 24 show an example of such a base 410 belonging to a device mechanism 400 of the socket type.
- Figure 24 shows well 420 of this receptacle.
- This base 410 has a generally parallelepiped shape, with a bottom 411 and a side wall 415 rising from the bottom 411.
- a sidewalk 416 extends projecting from the side wall, around the latter, for mounting the base 410 in an electrical equipment box (not shown).
- the bottom 411 has a rear face 411A and comprises insertion ducts 412 opening, on the one hand, towards the exterior on this rear face 411A of the base 410 and, on the other hand, towards the interior on the two openings 114 of said connection terminal 100 housed in base 410.
- These insertion conduits 412 thus form the inputs giving access to this connection terminal 100.
- Each insertion duct 412 extends along a longitudinal axis Y.
- the longitudinal axes Y of the insertion ducts 412 coincide respectively with the axes of said corresponding openings 114 of the connection terminal 100.
- Each insertion duct 412 is internally delimited by an internal face 413 of complex shape.
- This internal face 413 has a generally conical shape such that the section of the insertion duct is reduced from the outside of the base 410 inwards.
- this internal face 413 comprises a rib 414 which extends towards the inside of the insertion duct 412. In the example represented in FIGS. 23 and 24, it extends parallel to the longitudinal axis Y of the insertion duct 412. This rib 414 guides the conductive wire 1 introduced into said insertion duct 412 towards the longitudinal axis Y of the latter.
- the insertion ducts 412 are arranged in pairs giving access to the two openings 114 of the same connection terminal 100.
- the insertion ducts 412 of each pair are arranged side by side.
- the two ribs 414 are located in a plane containing the longitudinal axes Y of the two insertion ducts 412, so as to be as far apart as possible.
- Each rib 414 provided in the insertion duct 412 and each tab 117 provided on the edge of the opening 114 of the associated connection terminal 100 are arranged on either side of the longitudinal axis Y of the insertion duct 412 corresponding and in the plane containing the two longitudinal axes Y of the insertion conduits 412 of the base 410, coinciding with the axes of the two openings 114 of the corresponding connection terminal 100.
- the angular range authorized for the insertion of the conductive wire 1 is limited both by the rib 414 of the base 410 on one side and by the tab 117 of the connection terminal 100 on the other.
- the direction of insertion 11 of the conductive thread 1 is thus precisely controlled.
- the maximum angle AM authorized between the direction of insertion 11 and the longitudinal axis Y of the insertion conduit 412 is for example less than 10 degrees, preferably less than 8 degrees (FIG. 24).
- the present invention is not limited to the embodiments described and shown in the various figures, but those skilled in the art will be able to add any variant to it in accordance with their spirit.
