Definitions

  • the present invention relates to an electrical contact, a cell provided holding and retention means and a device for connecting this contact in this cell.
  • tubular contacts comprising stabilizing bosses and elastic return elements adapted to come to rest above and below the walls of the cell in which they are arranged. These tubular contacts are essentially designed to be placed in intermediate or slave connectors in sort of limiting the damaging effects of repeated connections on final connectors mounted on supports, during the tests.
  • contacts are double, male / female and the elastic elements including they are provided, avoid the removal of these contacts out of the cell in which they are introduced, in one direction as in the other.
  • Each contact is made from a flat blank and rolled to give it its configuration substantially cylindrical definitive.
  • US-A-5,035,656 describes a contact intended to be mounted more particularly in terminal blocks themselves intended to be attached on a printed circuit board.
  • Such contacts are very small so that it is possible to make them from solid rigid wire.
  • Means of retention are constituted in this embodiment, by rows of teeth superimposed, coming from deformation of the contact barrel and oriented on both sides on the other side of said barrel, at 180 °.
  • the maintenance is ensured depending on the nature and hardness of the material constituting the cell, which is random because increases temperature or the natural creep of the material can decrease very significant retention power of teeth.
  • the present invention aims to provide a retention device which is simple, which can be applicable to even important sections because making this cut / rolled contact, which ensures immobilization of the contact in its cell, both in translation and in rotation.
  • This contact can be provided with means to allow its mounting on a printed circuit board with the appropriate holes and it can be produced by cutting / rolling while remaining supported by a carrier strip for use in automatic on chain.
  • the electrical contact according to the invention cylindrical comprising an area for connection to a complementary contact, an area for tubular external profile forming a planned retention and retention zone to cooperate with a cell of an insulating body and a termination zone electric, is characterized in that this retention and retention zone includes elastically deformable retention means which fit in the tubular profile of the retention zone.
  • These means include a key receiving window integral with the internal wall of the cell and projecting into the cell, with retention teeth intended to hang in the key.
  • the invention also covers a cell for receiving such a contact.
  • electric tubular comprising a through hole, provided with a key radial, projecting into said hole.
  • connection device comprising such a contact and such a cell, the different elements having a profile such that they authorize the introduction of contact and that they oppose the withdrawal of the contact outside the socket.
  • a connector 10 is shown schematically comprising an insulating body provided with cells 12 adapted to receive each a contact 14, in particular of the tubular type as shown in detail in Figure 3A.
  • Each cell includes a part of the connection device for every contact she receives.
  • This part of the connection device is consisting of a key 20, coming from manufacturing with the cell of the connector.
  • This key 20 is radially projecting into the socket on a small depth and this key has a suitable thickness.
  • the tubular contact 14 preferably produced by cutting / rolling, comprises a first zone 22 for connection to a complementary contact, a second zone 24 for holding and retaining and a third zone 26 for connection termination.
  • connection zone 22 is of a diameter adapted to the diameter of a complementary tubular contact, planned to cooperate with this contact.
  • this contact type has a termination zone diameter of the order of one a few millimeters.
  • the second zone 24 for holding and retaining is of a diameter substantially identical to that of cell 12 which receives the contact so as to allow its insertion into said cell.
  • the diameter of the termination zone 26 to be welded is adapted to the diameter of the hole made in a printed circuit for example and provided for receive such a contact.
  • an area of transition is made between termination zone 26 and zone 24 of retention and retention so as to make up for the significant difference of diameter.
  • the contact includes over its entire height a slot 34 for joining the edges of the blank used for manufacturing the contact by cutting / rolling.
  • this slot comprises at at least one opening 36 for receiving the key.
  • This opening is of width greater than the thickness of the key. This opening is not a necessity but it is advantageously provided in the mode of preferential realization to facilitate the establishment of the contact like that will be explained further.
  • the opening 36 gives in a window 40 of a width less than the thickness of the key. This window is between the opening 36 insertion and a stop 38, that is to say on at least part of the zone 24 maintenance and retention.
  • this window includes retaining means 42, composed of at least one pair of teeth 44, arranged opposite, in the occurrence 3 pairs of teeth, inscribed in the curved surface of the area holding, that is to say in the thickness of the tubular wall.
  • the teeth are oriented so as to allow contact to be inserted into the socket and to avoid removing this contact from the socket.
  • the depth of the key is at least greater than the thickness of the metal blank from which the contact by cutting / rolling originates to form a tubular body.
  • FIG. 4A we can see the position that the area of maintenance and retention in the receiving cell.
  • the electrical contact is introduced through its zone 22 of termination in the cell 12 chosen. This contact is inserted until the zone 28 low transition with zone 24 of retention and retention comes at the upper edge of the cell 12.
  • the rotation should be oriented contact so that the slot 34 is substantially opposite the key.
  • the zone 24 for holding and retention expands radially, simultaneously and proportionally.
  • the retention and retention zone 24 comes into pressure against the wall of the socket, and an insertion effort must be exerted to introduce all of the the zone 24 for holding and retaining in the cell. At the same time, the teeth 44 bite in the key.
  • FIG. 4B a contact has also been shown introduced into a cell which itself includes a shoulder 14 in the lower part.
  • This shoulder has a profile complementary to that of transition zone 28 of the contact so that after complete introduction, this transition zone 28 comes to rest on this shoulder 14. This shoulder can thus come into replacement and / or in addition to the stop 28.
  • the contact is thus perfectly maintained in its cell, even if the material of the cell has a creep due to the temperature or its aging. In the event that such a contact is put in place in a cell of a connector subjected to vibrations, the contact remains linked to the connector and does not undergo degradations engendered by relative free movements between the contact and the socket.
  • the contact In the case of the stop 38 or the presence of the shoulder, the contact must be fully inserted into the socket until the stopper 38 comes in press on the upper end of the key and / or until you press on the shoulder.
  • the expansion of the retention and retention zone 24 has repercussions on part on the other two zones 22 and 26, but much weaker, so that the junction slot 34 remains almost contiguous in these two zones.
  • the contacts according to the present invention can be made from blanks cut and rolled while leaving these contacts connected to a strip 46 carrier.
  • the contacts can be cut so that they remain fixed by one end, that of the termination zone 22 to be inserted, see figure 6A or by the other end, that the termination zone 26 to be welded, see Figure 6B.
  • connection part 22 is of the female type.
  • connecting part 26 it can also be present in the form of a welding barrel but also in the form of a termination of connection to an electric wire.
  • the opening 36 of the window 40 can be turned symmetrically by relative to a midpoint. Contact is then introduced through the front of the body insulator of connector 10, which allows in particular in the case of a contact to female connection part to have a diameter of the holding area 24 and retention lower than that of connection area 22.
  • the cell may also have a shoulder in the upper part of the hole which then cooperates with the transition zone 30 high.
