  • connection pin 272 and the distance between the mouth 284 and the base 283 of the female connection element 280 are adapted such that the connection pin 272 can be housed mainly inside the the female connection element 280.
  • a root 272B of the connection pin 272 opposite its free end and the mouth 284 of the female connection element 280 extend substantially in a plane parallel to the rear face 213 of the housing 210. This ensures a satisfactory electrical connection between these two elements.
  • connection pin 272 and the mouth 284 of the female connection element 280 extend in a plane perpendicular to said main side faces 212 of the housing 210. This ensures that the male connection element 270 of a first electrical terminal block 200 is located opposite a female connection element 280 of a second similar neighboring electrical terminal block.
  • the housing 210 of the electrical terminal block 200 has two side slots 218, 219 provided in the main side faces 212 and each adapted to the passage of said connection pin 272.
  • a first 218 of these two lateral slots allows a portion of the male connection element 270 to pass such that the connection pin 272 extends outside the housing 210.
  • the first slot 218 is wide enough to pass the connection pin 272 as a whole when it moves from the connection configuration to the offline configuration and vice versa.
  • Internal partitions 218A of the housing 200 extend from the first slot 218 and define a housing for the male connection element 270 in which it can slide.
  • a second 219 of these side slots is adapted to allow the connection pin of another similar electrical terminal block to pass for its electrical connection with said electrical terminal block ( figure 5 ).
  • the second lateral slot 219 extends the opening 286 of the front face 214 which gives access to the mouth 284 of the female connection element 280 on the front face of the terminal block.
  • connection pin 272 of the other electrical terminal block can be inserted into the female connection element 280 by a translation movement of the pin back and forth in a direction parallel to the main lateral faces 212 or by a movement of lateral translation in a direction perpendicular to the main lateral faces 212.
  • the user determines the number of electrical terminal blocks 200 necessary for his electrical installation.
  • the user takes the electrical terminal block 200 in its offline configuration. It positions the electrical terminal block 200 against the other terminal block, such that the main side faces facing the two terminal blocks extend against each other. Then, he applies his finger or a tool against the operating part 291 of the actuator 290 and slides it into the window 216 of the housing 210 of the electrical terminal block 200. In doing so, the connection pin 272 of the male element of connection 270 slides out of the housing 210 through the first slot 218 of this housing 210 and enters the female connection element of the other terminal block, through the second slot of this other terminal block.
  • the user can connect the electrical terminal block 200 by first positioning the connection pin in its connection configuration, placing the electrical terminal block 200 to be connected in front of the other terminal block, then moving it backwards until the connection pin 272 of the electrical terminal block 200 enters the female connection element of the other electrical terminal block, in a translational movement parallel to the main lateral faces of the other terminal block.
  • the two electrical terminal blocks are connected, they can be mounted in the electrical cabinet or fixed in their final housing.
  • the other electrical terminal block can already be mounted in the cabinet, or fixed in its housing before connection with the electrical terminal block 200 concerned.
  • the electrical terminal block 200 can be mounted in the cabinet or fixed in its housing simultaneously with its connection to the other terminal block (for example by clipping) or after the connection.
  • the electrical terminal block 200 After factory manufacturing of the electrical terminal block 200 or after disconnection of an electrical conductor from each connection terminal, the electrical terminal block is in an unarmed arrangement.
  • the leaf spring 240 In this unarmed arrangement, the leaf spring 240 is at rest: it is not constrained by the pusher 230. On the contrary, the elbow 244 of the leaf spring 240 cooperates with a part of the cooperation surface 234 of the pusher 230 presenting a concave curvature, hollow, near the foot 233 of the pusher 230. The elbow 244 exerts at this level a pressure on the cooperation surface 234 of the pusher 230 which pushes it forward, through the opening 217A of its reception conduit 217.
  • the actuating head 231 of the pusher 230 projects from the housing 210 of the electrical terminal block 200 through the opening 217 of the front face 214 of the housing 210.
  • the stop elements of the pusher 230 prevent the pusher from leaving the housing 210.
  • the leaf spring 240 is in its shutter configuration: the free end of the interaction branch 242 extends into the insertion conduit 211 of the housing 210. Access to the connection terminal is blocked since if a electrical conductor is inserted into the insertion conduit 211, its end hits against the free end of the interaction branch 242 of the leaf spring 240.
  • the intermediate part 260 is contactless and without interaction with the pusher 230.
  • the retaining part 261 of the intermediate part 260 extends parallel to the direction of movement D2 of the pusher 230.
  • the actuation part 262 of the intermediate part 160; 260 is housed largely in the insertion conduit 211.
  • a first step consists of arming the spring blade 240 of each connection terminal, that is to say placing it in the waiting configuration. To do this, the user pushes the pusher 230 by pressing on the actuating head 231 thereof which protrudes from the housing 210.
  • the front face of the actuating head 231 of the pusher 230 has a slot; 237 allowing the insertion of the end of the tool, for example a screwdriver ( figure 1 ).
  • the thickness of the part of the pusher 230 in contact with the blade spring 240 gradually increases when pusher 230 moves from the raised position to the depressed position. This thickness is measured in a direction substantially orthogonal to the direction of movement of the pusher 230 ( figures 3 , 4 , 9 ).
  • the pusher 230 By sliding along the direction of movement, the pusher 230 thus progressively pushes the elbow 244 of the spring blade 240 in a direction substantially orthogonal to the direction of movement of the pusher 230, towards the insertion conduit 211 of the housing 210.
  • the blade spring 240 thus passes into its waiting configuration when the pusher 230 is pressed into its receiving conduit 217: the two parts of the support branch 241 of the blade spring 240 forming a U approach each other, the branch of interaction 242 is moved towards the insertion conduit 211.
  • the window 243 of the interaction branch 242 is offset and is placed in the insertion conduit 211, at the outlet of the well 211B, so as to free access to the connection terminal ( figures 3 And 4 ).
  • connection terminal of the electrical terminal block 200 is thus armed and ready to receive an electrical conductor for its connection ( figures 1 to 4 ).
  • each connection terminal of the electrical terminal block 200 is armed at the factory in order to be delivered ready for use for the user.
  • the pusher 230 When the pusher 230 is in its depressed position, the pusher 230 is entirely housed in the housing 210. Its actuating head 231 is flush with or is set back from the front face 214 of the housing 210 ( figures 1 And 2 ).
  • the fact that the pusher 230 does not protrude from the housing 210 in its depressed position visually indicates to the operator that the corresponding connection terminal is armed.
  • the access opening 211A of the insertion conduit 211 makes it possible to verify that the connection terminal is accessible for the electrical conductor.
  • a second step in the implementation of the electrical terminal block 200 consists of introducing the electrical conductor into the insertion conduit 211 of the housing 210 ( Figure 3 ).
  • This is for example an electrical conductor of the flexible cable type with a crimped end.
  • Other types of electrical conductors can, however, be used.
  • the end of the electrical conductor passes through the access opening 211A, into the well 211B partially delimiting the insertion conduit 211 and through the window 243 of the interaction branch 242 of the spring blade 240. End of the electrical conductor is introduced between the edge of the opening of the window 243 of the interaction branch 242 of the spring blade 240 and the conductive bar 250 ( figures 3 , 4 And 6 ).
  • the retaining part 261 of the intermediate part 260 pivots around the pivot axis B2 defined by the pin 266 of the intermediate part 260, towards the part actuation 262. In doing so, the hook formed by the free end of the retaining part 261 disengages from its cooperation with the foot 233 of the pusher 230 and releases the latter.
  • the pusher 230 no longer being retained in its depressed position, it rises towards its raised position under the pressure of the spring blade 240 which tends to return to its initial shape, that is to say its shape at rest in the configuration of 'obturation.
  • the cooperation surface 234 of the pusher 230 is thus adapted to cooperate with the elbow of the spring blade 240 so as to move the pusher 230 forward.
  • the elbow 244 of the spring blade 240 slides on the cooperation surface 234 of the pusher 230 and thus pushes the latter towards the outside of the housing 210.
  • the pusher 230 then moves in translation along the direction of movement D2 until so that the abutment elements of the pusher abut against the abutment walls of the housing 210.
  • the elbow 244 is positioned against the concave curvature part of the cooperation surface 234 of the pusher 230.
  • the window 243 of the interaction branch 242 of the spring blade 240 moves and its edge tightens the electrical conductor inserted in the insertion conduit 211 against the conductive bar 250.
  • This movement of the spring blade 240 results in an audible signal of the “click” type which indicates to the operator that the connection is made.
  • the electrical connection is established only when the pusher 230 is released from its cooperation with the retaining part 261 of the intermediate part 260, that is to say when the electrical conductor is completely inserted into the insertion conduit 211 and presses on the actuation part 262 of the intermediate part 260.
  • connection terminal must be re-armed to accommodate a new electrical conductor.
  • connection terminal is armed and ready to accommodate a new electrical conductor.
