Definitions

  • the present invention relates to an electrical module for ground connection comprising a contact arrangement defining a shunt and a plurality of male contacts intended to receive contacts females attached to the ends of conductors to be connected to ground, means for retaining female contacts on male contacts, means for fixing the module on a support and establishing a connection electric between said contact arrangement and said support, and insulating means for confining the contacts in the module.
  • the contact arrangement is consists of a circular metal plate on which a multitude of Individual pin-shaped male contacts are attached to a circle.
  • the retention means consist of a plurality of sockets with metal fins attached in a housing made of insulating material which comes to bear on the metal plate by surrounding the male contacts.
  • the male contact parts are surrounded by sleeves which serve as support with winged sockets.
  • An additional element is provided to ensure assembly of the housing with the metal plate.
  • the main drawback of this known module consists in its high cost, due in particular to the large number of its constituent parts (high manufacturing costs, long and expensive assembly).
  • the present invention relates to an electrical connection module for mass which is distinguished in particular by a very small number of parts which can be assembled simply and quickly, to a reduced cost.
  • the electrical module for ground connection, object of the invention comprises a contact arrangement consisting of a one-piece male shunt-contact assembly.
  • the male shunt-contact assembly is formed by wiring, for example aluminum or aluminum alloy.
  • the housing has tabs latching cooperating with the male shunt-contact assembly, preferably snap tabs cooperating externally with said set.
  • the through holes of the housing include, in the area located between the retention fins and said face of the housing, ribs of guide for the female contacts, these ribs projecting radially inward.
  • the retention fins are distributed at the way of petals around the edge of a through hole and the ribs of guidance are angularly offset with respect to the retention fins, preferably by being located angularly in a position insert between each two adjacent retention fins.
  • the single figure in the drawing is an axial section of the module assembled.
  • the electrical module 1 for ground connection as illustrated by the single figure of the drawing, is intended to allow connection to earth a plurality of unrepresented conductors, for example twelve conductors. Each of these conductors has at its end a female contact tip fixed by crimping to the conductor and having a circular retention shoulder. Such female contact tips are well known and are commonly used, for example, in the aeronautics.
  • Module 1 includes, for grounding the end caps conductors, a contact assembly 2 consisting of a shunt plate 3 circular, carrying on a face a plurality of male contacts 4 in in the form of pins, for example twelve contacts 4 distributed on a circle.
  • the contacts 4 and plate 3 are made in one piece, preferably by aluminum or aluminum alloy wiring.
  • plate 3 can have a diameter of the order of 15 mm and each contact 4 can have a diameter of the order of 0.8 mm over a length of the order of 2.4 mm.
  • the plate 3 is pierced with a central hole 5 for the passage of the rod 7a with a screw 6, the head 7b of which bears on the upper face of the plate 3 by through a washer 8 and which is used for fixing the plate 3, therefore of module 1, on a support structure, not shown, forming a mass.
  • a housing 9 is attached to the assembly contact 2, on the upper face of the plate 3.
  • the housing 9 of form general cylindrical, has a central hole 10 whose diameter is slightly greater than the diameter of the head 7b of the screw 6, except at the place an inner rim 11 provided in the vicinity of the upper end of the box 9.
  • the box 9 has externally, at its end lower, several locking tabs 12 which cooperate with the outside of the plate 3, when the housing 9 fits into the assembly contact 2, after engagement of the rod 7a of the screw 6 from the top in the hole 5 of the plate 3. After snap-on of the housing 9 on the assembly of contact 2, the head 7a of the screw 6 is thus held captive in the module, thanks to the inner rim 11 of the housing 9.
  • the housing 9 has, at the location of each male contact 4 of contact assembly 2, a through hole 13 extending through the housing 9 over the entire height of the latter.
  • each hole passage 13 contains several retention fins 14.
  • the retention fins 14 of each through hole 13 are three in number, being angularly evenly distributed over the around, like petals. The fins 14 of each through hole 13 converge downwards towards the male contacts 4.
  • each passage hole 13 contains several longitudinal ribs 15.
  • the ribs 15 are three in number and are distributed uniformly around the perimeter, being angularly offset from to the fins 14 so as to be located angularly in position interlayer with respect to the fins 14.
  • the ribs 15 provide the guiding the female contacts (ferrules) of the conductors below the retention fins 14 and thanks to their angular position offset by compared to the fins 14, they do not interfere with the molding and demolding of the fins 14. Nevertheless, they provide guidance and centering of the female contacts, so that these contacts fit together without problem on the male contacts 4 of the contact assembly 2, when they insertion into the through holes 13 of the housing 9.
  • the housing 9 can be molded from a single piece of plastic, not only with the tabs latching 12, but also with the retention fins 14.
  • connection module as shown and described consists of therefore of a very reduced number of constituent parts, namely of a contact assembly 2 one-piece, a housing 9 one-piece, a screw 6 and a washer 8 (and possibly an O-ring 16 clipped onto a lower shoulder of the plate 3), the assembly of these five parts being particularly simple insofar as it does not involve any machining or forming operation.
  • a similar module comprises, for twelve contacts, thirty-one component parts, namely a housing, a shunt plate, twelve male contacts in the form of pins attached and fixed by crimping on this plate, twelve retention sockets with fins, twelve sleeves surrounding the male contacts to serve as support for the retention, a housing assembly sleeve with the shunt plate and a seal molded under the shunt plate.
  • plate-shunt 3 not by aluminum or alloy wiring aluminum, but for example by stamping and / or other metals or alloys, for example based on copper.
  • the wiring presents however the advantage of leading to perfectly cleared male contacts 4, which is not always the case with other methods.
