Definitions

  • the invention relates to a connector for conductors. electrical and a method of manufacturing such a connector.
  • connectors comprising at least two receptacles for receiving and immobilizing the end of a driver, these housings being accessible by the same face of the connector, commonly known as the front face.
  • a known connector 151 for example from EP-A-0 311 537, is shown in Figure 6. It includes two holes parallel 152 and 153 each intended to receive the end stripped 154 or 155 from a conductor 156 or 157. Screws 158 and 159 are inserted into threads 160 and 161 perpendicularly at holes 152 and 153. Note that screws 158 and 159 are of different lengths, so they are not interchangeable. The length of the bare parts 154 and 155 must be different because Part 154 should not abut and deform against the screw 161, while the part 155 must be long enough to cooperate with this screw 161. In particular, given the length of the section stripped 155, the positioning of the conductor 157 is delicate because it is done blind over a long length.
  • Another object of the invention is to provide a lighter and simpler connector than those of prior art, therefore of lower cost price.
  • the invention relates to a connector for electrical conductors comprising at least two housing reception and immobilization of the end of a conductor, the housings being accessible by the same face of the connector, said front face, which is inclined relative to the direction of insertion of the ends of the conductors into housing.
  • This connector is characterized in that at least a thread for receiving a locking screw of the end of a conductor is accessible from this face before.
  • the connector according to the invention achieves the aims mentioned above insofar as the entrances to the dwellings of reception and immobilization of the ends of the conductors can be shifted forward thanks to the inclination of the front face.
  • the connector is made from an extruded, sectioned profile according to an oblique plan.
  • This aspect of the invention allows a particularly economical construction of the connector the invention.
  • the angle of inclination of the front face or of the sectioning plane by relative to the direction of introduction of the ends of the conductor is between 30 and 60 °, preferably around 45 °. These tilt angle values allow to obtain an adequate offset of the inlet ports of the housing considered.
  • the connector comprises at least a first rib provided with a tapping for receiving a locking screw, this tapping being shifted forward from the leading edge by one second rib located immediately above the first rib.
  • the offset of the threads for receiving the locking screws allows easy access to these screws without the need to drill a or more ribs located immediately above the rib considered.
  • the connector includes at least three receptacles and immobilization, each housing separation rib being provided with a thread offset forwardly relative to the front edge of another rib located immediately above of the separation rib.
  • the housing dividing ribs include two sails substantially parallel, the tapping of each rib being provided in a first veil, a screw being inserted in this tapping to immobilize the end of a received conductor in a housing without protruding, in the locked position, beyond of the surface of the second veil of the rib facing towards a adjacent accommodation.
  • the screws the individual conductors do not protrude in the housing of neighboring conductors, which avoids deform the stripped end of a conductor being inserted in an adjacent accommodation.
  • the second veil advantageously comprises a recess to the right of the tapping to allow the setting place and operation of the screw.
  • the dwellings are offset from each other in a direction substantially perpendicular to the direction of introduction of the ends of the conductors and perpendicular to the locking screw. This facilitates access to these screws and allows to nest two adjacent connectors.
  • the invention also relates to a manufacturing method a connector as previously described and, more specifically, a process characterized in that it consists in extruding a profile comprising at least two internal channels and cut this profile in a direction oblique to to the extrusion direction.
  • This particularly simple process and economical provides a connector at a lower cost reliable and light.
  • the method also consists to be made, in each rib separating said channels, at minus a thread for receiving a locking screw driver. It can also be provided that the method consists to perform the tapping in a first veil of the rib and to cut a recess in a second veil of the rib at right of this tapping.
  • the connector 1 shown in Figures 1 and 2 includes two housings 2 and 3 for receiving the stripped ends 4 and 5 of two electrical conductors 6 and 7. Two screws 8 and 9 are respectively provided in threads 10 and 11 for immobilize the ends 4 and 5 in the housings 2 and 3.
  • a plate 12 is provided on an upper part of the connector 1 to connect the connector to a fuse, not shown, by means of a cable 13.
  • the front face 1a of the connector 1 is inclined by an angle ⁇ 1 with respect to the direction of insertion of the ends 4 and 5 in the housing 2 and 3 shown by the arrow F.
  • the screws 8 and 9 can be located approximately the same distance from the inputs 2 a and 3 a while being accessible, so that the length of the stripped ends 4 and 5 of the cables 6 and 7 can be substantially identical.
  • the internal thread 11 intended to receive the screw 9 is formed in a rib 14 consisting of a first veil 15 bordering the housing 3 and a second veil, or upper veil, 16 bordering the housing 2. It is noted that the veil 16 has a recess 16 a at the right of the housing 16. In addition, the axis YY 'of the thread 11 is offset forward, that is to say in the direction of the inlet 3 a relative to the front edge 17 a of a second rib 17 bordering the housing 2.
  • the length of the screw 9 is provided so that in tight position, i.e. when the cable is immobilized 7 in the housing 3, the head of the screw 9 does not protrude above of the surface of the web 16 facing the housing 2. Thus, the screw 9 is not likely to interfere with the end 4 conductor 6, when it is in place in the housing 2.
  • screws 8 and 9 can have the same length, which allows you to use only one screw reference with the connector of the invention.
  • the connector 1 is made very simply by extruding an aluminum profile comprising two internal channels, intended to form the housings 2 and 3 and extending in the direction of extrusion, and by cutting this profile according to a direction D 1 which is inclined relative to this direction of extrusion. Indeed, the direction of extrusion is generally parallel to the arrow F, so that the inclination of the direction D 1 results in the desired inclination for the front face 1 a .
  • the threads 10 and 11 are then produced in the ribs 14 and 17.
  • the thread 11 is produced after cutting the recess 16 a in the web 16. It is noted that the angle ⁇ 1 is of the order of 30 °, which gives good accessibility to screw 9.
  • a connector 51 comprises three housings 52, 53 and 53 'for receiving the stripped ends 54, 55 and 55' of three conductors 56, 57 and 57 '.
  • Screws 58, 59 and 59 ' are respectively provided in threads 60, 61 and 61' respectively formed in ribs 67, 64 and 64 '.
  • Recesses 66 a and 66 ' a are provided in the webs 66 and 66' for the passage of the screws 59 and 59 '.
  • the front face 51 a of the connector 51 is inclined, in a direction D 2 relative to the direction of introduction of the ends 54, 55 and 55 'in the housings 52, 53 and 53' represented by the arrow F.
  • the angle ⁇ 2 of inclination of the front face 51 a is of the order of 45 °, so that the total width L 2 of the connector 51 is roughly identical to the total width L 1 of the connector 1 of the embodiment of FIGS. 1 and 2.
  • increasing the value of the angle of inclination of the front face of the connector makes it possible to increase its compactness.
  • the angle ⁇ 2 should not be too great because the threads 61 and 61 'should remain offset forwards with respect to the front edge 67 a or 64 a of the rib 67 or 64 located immediately above of the rib 64 or 64 'in which they are made. In practice, this angle is kept below 60 °.
  • the connector 51 is produced by extruding an aluminum profile comprising three internal channels intended to form the housings 52, 53 and 53 '. This section is sectioned in the direction D 2 , which makes it possible to obtain the angle of inclination ⁇ 2 of the front face 51 a .
  • the manufacturing range of connector 51 is similar to that of connector 1.
  • a connector 101 includes three housings 102, 103 and 103 'of receiving the stripped ends 104, 105 and 105 'of three conductors 106, 107 and 107 '. Screws 108, 109 and 109 'are respectively provided in threads 110, 111 and 111 ' respectively formed in ribs 117, 114 and 114 '.
  • the front face 101 a of the connector 101 is inclined, in a direction D 3 relative to the direction of introduction of the ends 104, 105 and 105 'in the housings 102, 103 and 103' represented by the arrow F.
  • the angle ⁇ 3 of inclination of the front face 101 a is of the order of 60 °.
  • the housing 103 is offset in a direction D 4 perpendicular to the plane of Figure 5. This facilitates access to the screw 109 by a screwdriver T. It is noted that two adjacent connectors can be partially nested one inside the other, which guarantees precise relative positioning of one with respect to the other.
  • This connector is manufactured in a similar manner to the previous ones, the extrusion die of the housing 103 being simply offset in the direction D 4 with respect to those of the housings 102 and 103 '.
  • the angle of inclination ⁇ 1 , ⁇ 2 or ⁇ 3 is acute.
  • the upper edge of the connector is set back relative to its lower edge, which gives access to the locking screws from above.
