    专利说明:

    [0001] The present invention relates to the field of connection of low-voltage electrical appliances and more particularly to a plug-in connector for terminal blocks. A withdrawable connector for a terminal block provides the electrical connection between a conductive electrical wire and a plug of the terminal block connected to a first connection portion. A plug-in connector can thus be replaced on a terminal block according to the characteristics of the electrical conductor to be connected, in particular according to its diameter.
    [0002] Thus, it is known to have a withdrawable connector for terminal block comprising: - an insulating body, - a connection terminal having a housing for a conductive electrical wire intended to be inserted through a first opening of the insulating body according to a insertion direction of the conductive electrical wire into the insulating body, and - a connection socket comprising a base from which extend two elastic connecting branches intended to provide electrical contact with a complementary terminal of the terminal block intended for cross a second opening of the insulating body.
    [0003] However, the connection terminal and the connection socket are arranged in the insulating body of the withdrawable connector independently. Indeed, the connection terminal is solely for the purpose of creating an electrical connection with the conductive electrical wire. The connection socket only has the function of creating an electrical connection with the complementary socket of the terminal block. The connection socket has no mechanical interaction with the conductive electrical wire which remains at a distance from it. In addition, the connection terminal exerts a clamping pressure on a portion of the conductive electrical wire located at a distance from its free end.
    [0004] Therefore, the insulating body includes a specific housing for receiving this end of the conductive electrical wire having passed through the connection terminal. The presence of this specific housing in the insulating body induces a minimum dimensioning of the dimensions of the withdrawable connector, in particular its height.
    [0005] Typically, a plug-in connector of the state of the art has an overall footprint of at least 40 mm. In some cases, the size of the plug-in connectors prevents the insertion of an additional row of connection blocks into a cabinet or an electrical cabinet. The present invention aims to solve all or part of the disadvantages mentioned above. To this end, the present invention relates to a plug-in connector as described above characterized in that it comprises a passage for the electrical conductor wire 10 connecting the first housing of the connection terminal and a second housing formed in the base of the connection socket. This arrangement makes it possible to reduce the size of the plug-in connector by assigning to the base of the connection socket the dual function of holding the elastic connection and housing legs for the conductive electrical wire. According to one aspect of the invention, the passage is made in the insulating body. Thus, for example, the absence of portions of the insulating body between the first housing of the connection terminal and the second housing formed in the base of the connection socket may make it possible to form a passage for the conductive electrical wire. . According to one aspect of the invention, the second housing is disposed in alignment with the first housing in the direction of insertion of the conductive electrical wire. This arrangement makes it easier to access the conductive electrical wire 25 to the second housing. According to one aspect of the invention, the base of the connection socket has a U-shaped profile. This arrangement makes it possible to easily create the base of the connection socket by extending the two elastic connection branches from the 30. two branches of the U-shape. According to one aspect of the invention, the connection terminal is of the leaf spring type. This arrangement makes it easier to insert the conductive electrical wire into the connection terminal.
    [0006] According to one aspect of the invention, the leaf spring type connection terminal comprises a conductive portion, said conductive portion and the connection socket being formed in one piece. This arrangement makes it easier to assemble the plug-in connector 5 while optimizing manufacturing costs. According to one aspect of the invention, the connection terminal of the leaf spring type comprises a leaf spring having a bearing leg and a clamping leg connected by a bend. This arrangement allows additional space saving in the insulating body 10 of the plug-in connector. According to one aspect of the invention, the insulating body comprises a portion disposed between the two elastic connecting arms and adjacent to the second housing. This arrangement makes it possible to create a stop so as to prevent the conductive electrical wire from interfering when inserting the plug socket of the plug-in connector into the complementary connection socket of the terminal block. According to one aspect of the invention, the plug-in connector has an overall size of less than 35 mm. In any case, the invention will be better understood with the aid of the description which follows, with reference to the appended schematic drawing showing, by way of non-limiting example, a plug-in connector according to the invention. Figure 1 an overview of a plug-in connector according to the invention in situation with a conductive electric wire. FIG. 2 is a view of a plug-in connector according to the invention in a situation with a conductive electrical wire but to which the insulating body has been removed. As illustrated in FIG. 1, a detachable connector 1 according to the invention comprises an insulating body 2, a connection terminal 10 and a connection socket 20. The insulating body 2 comprises a first opening 3 intended to allow the insertion of a conductive electrical wire C, a second opening 4 intended to allow the insertion of a male plug of a terminal block (not shown). In addition, the insulating body 2 comprises a third opening 5 for inserting a tool (not shown).
    [0007] In the example presented, the connection terminal 10 is of the spring type and comprises a conductive portion 11 disposed in the insulating body 2 and a leaf spring 16. The conductive portion 11 is fixed in the insulating body 2.
    [0008] The conductive portion 11 comprises a first portion 12 and a second portion 14 connected by a bend 15. The first portion 12 has an opening 13 disposed facing the first opening 3 of the insulating body 2. In addition, the first portion 12 s' extends substantially in a plane inclined relative to a plane transverse to the insertion direction D of the conductive electrical wire C. The second portion 14 is solid and extends substantially in a plane substantially parallel to the direction D of insertion of the wire The first portion 12 and the second portion 14 are made of an electrically conductive material. In addition, the leaf spring 16 of the connection terminal 10 comprises a first support branch 17 bearing on a first edge of the opening 13 of the first portion 12 and a movable clamping leg 18 for tightening the wire electrical conductor C against a second edge of the opening 13 of the first portion 12 opposite the first edge and against the second portion 14 of the connection terminal 10. The support leg 17 and the clamping leg 18 are connected by a The removal of the conductive electrical wire C from the insulating body 2 can be achieved by applying a stress on the clamping leg 18 of the leaf spring 16 by means of a tool inserted through the third opening 5. connection terminal 10 thus forms a housing 8 for the conductive electrical wire C introduced into the insulating body 2 through the first opening 3. In the example proposed, this housing 8 can be defined as being a zone of the space in situ e substantially between the two planes in which substantially extends the first portion 12 and the second portion 14 of the conductive portion 11 of the connection terminal 10 and a plane substantially transverse to the insertion direction D of the conductive electrical wire C in the insulating body 2 in which is inscribed the free end of the first portion 12 of the conductive portion 11 35 of the connection terminal 10.
    [0009] The connection socket 20 comprises a base 21 having a U-shaped profile having a base 21a and two branches 21b, 21c. The branches 21b, 21c of the U-shape of the base 21 extend substantially in a direction transverse to the insertion direction D of the conductive electrical wire C in the insulating body 2 and in two planes substantially parallel to the plane in which extends the second portion 14 of the conductive portion 11 of the connection terminal 10. In addition, in the example presented the second portion 14 of the conductive portion 11 of the connection terminal 10 is directly connected to a side edge of one of the branches 21b of the U-shaped base 21 facing the connection terminal 10. In addition, this branch 21b of the base 21 and the second portion 14 of the conductive portion 11 of the connection terminal 10 extend in the same plane. Finally, the connection socket 20 comprises two elastic connecting arms 22a, 22b each extending from one of the two edges of the branches 21b, 21c of the U-shaped base 21 opposite the two facing edges. the connection terminal 10. These two elastic connection branches 22a, 22b form a socket 20 and are intended to provide electrical contact with a male terminal of the terminal block (not shown) intended to be inserted between the two connection branches 22a, 22b through the second opening 4 of the insulating body 2. In the example shown, and as shown in Figure 2, the connection socket 20 comprising the base 21 and the two elastic connection branches 21a, 21b are formed in one piece with the conductive portion 11 of the connection terminal 10 comprising the first portion 12 and the second portion 14. The base 21 of the connection socket 20 forms a second housing 9 in addition to the first housing 8 for the conductive electrical wire C introduced into the insulating body 2 through the first opening 3. In the example shown, this second housing 9 can be defined as being an area of the space located substantially between the two branches 21b 21c of the U-shaped base 21 of the connection socket 20. Similarly, in the example presented the second housing 9 is arranged in alignment with the first housing 8 for the conductive electrical wire C of the terminal. 10 according to the insertion direction D of the electrical conductor wire C.
    [0010] In addition, the detachable connector 1 comprises a passage 6 between the first housing 8 and the second housing 9 in order to allow the end C 'of the conductive electrical wire C to reach the second housing 9 after having passed through the first housing 8.
    [0011] This passage 6 results from the absence of portions of the connection terminal and / or the connection socket 20 and / or the insulating body 2 between the first housing 8 and the second housing 9. Finally, the insulating body 2 comprises a portion 7 disposed between the two elastic connection legs 22a, 22b and adjacent to the second housing 9 so as to prevent the end C 'of the conductive electrical wire C from reaching the connection socket 20. The withdrawable connector 1 has an overall height or height of less than 35 mm against a footprint of at least 40 mm for a plug-in connector of the state of the art.
    [0012] This space saving, due to the presence of the second housing 9, reduces the gap between the support rails of the terminal blocks and therefore increases the number of blocks that can equip a cabinet or an electrical box. Although the invention has been described in connection with particular embodiments, it is obvious that it is not limited thereto and that it includes all the technical equivalents of the means described and their combinations. Thus, in a non-illustrated embodiment, the second housing 9 is not disposed directly in alignment with the first housing 8 in the insertion direction D of the conductive electrical wire C but is slightly offset relative to to this one. In such an embodiment, the conductive electrical wire C passes through the first housing 8 and is guided towards the second housing 9 through the passage 6 by sliding along the second portion 14 of the conductive portion 11 of the connection terminal 30 10.
