Definitions

  • the present invention relates to a contact part for a connector female, made by cutting and folding from a ribbon of conductive metal, and of the type comprising two contact blades (5 and 6), intended to establish electrical contact with a contact (19), engaged therebetween, of a male connector.
  • the two contact blades are often formed in such a way that they are in contact or almost in contact with each other when they are at rest, that is to say when no contact tab of a male connector is not engaged between them. Under these conditions, we is sure to get excellent electrical contact in service.
  • such an arrangement requires relatively force important to engage the contact tab of the male connector between the contact blades of the connector contact piece female. This force can be very important if the male connectors and female have a large number of channels, so a large number of contact parts whose tabs must be engaged in the blades.
  • contact parts for female connector in which the two contact blades are preformed so as to present, at rest, a spacing which is greater than that of the contact blades of the aforementioned contact parts, but which however remains smaller than the thickness of a contact tab of the male connector.
  • the necessary force to insert the contact tab of the male connector between the two contact blades of the contact piece of the female connector is significantly smaller than in the case of the known part of contact described first, but then it's harder to guarantee an excellent and lasting electrical contact in the time between the two contact blades of the contact piece of the female connector and the contact tab of the male connector, to because of manufacturing tolerances for contact parts and male and female connector housings, and / or because of aging of contact blades.
  • the main object of the present invention is therefore to provide a contact piece for female connector, which requires only one relatively low force to engage between its two blades contact the contact tab of a male connector, while providing good electrical contact.
  • the invention has the alternative aim of providing a piece of contact usable in a female connector called "through”, that is to say with which the contact tab (s) of the male connector can be engaged in the connector contact part (s) female both through the front face and through the rear face of the female connector.
  • the invention also has the alternative objective of providing a piece of contact of the aforementioned type, which can be mass produced, economically, with low losses of metal, and which has a relatively small dimension in the direction of insertion of the tabs contact, so that a female connector using one or several contact parts according to the invention can itself have a relatively small thickness, measured between its front faces and back.
  • the subject of the invention is a contact piece for a female connector, manufactured by cutting and bending from a strip of conductive metal, comprising a cage with a U-shaped cross section, having a rectangular central wall and two lateral wings parallel to each other, which are connected in one piece respectively to first and second opposite sides of the median wall, a connecting part which is connected in one piece to a third side of the median wall, to one end of the U-shaped cage, for the electrical connection of the contact piece to an external circuit, two contact blades which are intended to establish electrical contact with a contact tab, engaged between them, of a male connector, and which are connected in one piece respectively to the lateral wings and are folded back inside the cage so as to converge towards the longitudinal median plane of said cage, the wall median having, roughly in the middle, a narrow strip of metal which has a predefined width l and which is defined by two parallel slots of equal length cut in the median wall of the cage, in the longitudinal direction thereof ci, each contact blade having on its longitudinal side which, after folding the contact
  • the two contact blades are resiliently supported, that is to say with a certain prestress, against opposite sides of the strip formed on the middle wall of the cage of the workpiece contact, and since this strip maintains, at rest, a predefined spacing between the two contact blades (this spacing must be less than the thickness of the contact tab of the male connector, for example about 2 thirds of this thickness), we is thus ensured that the effort required to engage the tongue of contact of the male connector between the two contact blades of the contact piece according to the invention will be relatively small and that, nevertheless, good electrical contact will be obtained thanks to the preload of the two contact blades.
  • the contact piece according to the invention may have a length, in the longitudinal direction of the two contact blades, which is significantly shorter than the length of the known contact parts in which the two contact blades are located substantially in the extension of their support.
  • the narrow strip of metal is stamped so as to protrude as a bridge inside the cage, without encroaching on the interval between the two contact blades, but only between their lugs.
  • said strip could consist of a short tongue cut in the middle wall of the cage of the piece of contact and folded back inside said cage, although in this last case, the support provided by said tongue is probably a little less stable than in the previous case.
  • each contact blade can be bent in its region where it is supported by its lug on the strip, such so that the two contact blades together form a first input converging for a male contact tab inserted by one end of the U-shaped cage and a second converging input, opposite the first convergent, for a tongue of male contact introduced by the opposite end of the U-shaped cage.
  • the contact part according to the invention can be used in a female connector called "through".
  • the contact part is writable in a square, the middle wall and the two lateral wings occupying approximately one half of the square, while the two blades of contact and the connection part located between them occupy half remaining of the square.
  • the contact part according to the invention can be produced with a minimum of metal losses.
  • the contact part can include two flexible retention tabs, for fixing the contact piece in a female connector housing, said retention legs being cut respectively in the wings of the cage and extending obliquely outside said cage, towards a end of it.
  • said retention tabs extend towards the end of the cage where the part of the connection.
  • said part of connection can be in the form of a fork with two branches, of which the branches are substantially aligned with the first and second sides of the middle wall to which the lateral wings of the cage.
  • the two branches of the part of connection form pins which can be engaged and fixed by soldering in corresponding holes of a support, for example a printed circuit board or board to which the connector female is intended to be fixed.
  • the invention also aims to provide a female connector of the type comprising a housing of insulating material having at least one cell containing a contact piece with two contact blades, said female connector being characterized in that said contact piece is a contact piece according to the invention, presenting one or more many of the features listed above.
  • Said housing has, in a manner known per se, a rear face which, in service, is intended to be placed opposite a face of a support such as a printed circuit board, and a front face opposite the back side.
  • said cell is open on the side of said rear face and closed on the side of said front face by a bottom wall which has a guide slot for a contact tab of a connector male, said guide slot having a longitudinal median axis which is located in the longitudinal median plane of the workpiece cage contact housed in the cell of the housing.
  • the contact piece is well protected and it also reduces the risk that bodies foreigners can enter the socket of the female connector, the absence of the male connector, and subsequently hamper the insertion of the contact tab of the male connector between the two blades contact of the contact part of the female connector.
  • said support for example a circuit board printed on which the female connector is mounted, has it also a guide slot aligned with the face guide slot front of the female connector housing, it can be used like a "through" connector.
  • said guide slot, said contact tab of the male connector and said strip of the contact piece of the female connector are dimensioned so as to satisfy the double inequality: L + l 2 ⁇ e ⁇ L in which l is the predefined width of the strip, L is the width of the guide slot and e is the thickness of the contact tab of the male connector.

  • the middle wall 4a of the cage 4 has, roughly in the middle, a strip 12 which projects inside said cage 4 (see also FIG. 4) and which has a predefined width l (FIGS. 2 and 3 .)
  • the strip 12 can be constituted by a narrow metal strip whose width l is defined by two slots 13 and 14, parallel and of equal length, cut in the middle wall 4a of the cage 4. Said narrow strip of metal is then stamped so as to project into a bridge inside the cage 4.
  • the two contact blades 5 and 6 are connected in one piece wings 4b and 4c respectively, on one side thereof same side of the cage 4 as the connection part 7.
  • the two blades contact 5 and 6 are folded back inside the cage 4, respectively around fold lines 15 and 16 ( Figure 3), of so as to converge towards the longitudinal median plane 10 of the cage 4.
  • Each of the two contact blades 5 and 6 carries on its longitudinal side which is turned towards the middle wall 4a of the cage 4, a lug 5a or 6a which rests elastically on one side of the strip 12, so that, at rest , that is to say in the absence of any contact tab of a male connector between the two contact blades 5 and 6, these latter blades are held under preload with a predefined spacing corresponding to the predefined width l of the strip 12.
  • each of the two contact blades 5 and 6 is bent, by folding around a fold line 17 or 18 (FIG. 3), in the region where it is supported by its lug 5a or 6a on the strip 12.
