Definitions

  • the present invention relates to a contact piece of the type female used in a connector, for example a connector MIL or any other specification, or for any other another application, as for example in a base for an integrated circuit, or intended to be placed on a printed circuit board.
  • the invention more particularly the portion of this contact piece intended to receive a corresponding element of the male type.
  • MIL standards including MIL-C 39029
  • MIL-C 39029 defines a number of characteristics that must be fulfilled by this portion of the contact piece, example the contact resistance, the insertion force and the extraction force of the male contact piece, the penetration distance of the male piece before contact is established, etc.
  • these various parameters are to measure both when the parts are new and after multiple uses and this under environmental conditions, temperature, humidity, etc. very diverse.
  • An object of the present invention is therefore to propose a piece of contact including a female portion intended to receive a corresponding male portion, of improved construction relative to known contact parts, so as to avoid the disadvantages mentioned of these contact pieces.
  • the female type portion of the piece of contact 1 intended to receive a corresponding element of the male type.
  • This male element consists of a stem, usually terminated by a hemispherical tip or truncated cone, and having a diameter determined.
  • This male element may be the male portion of a piece of corresponding contact or else an integrated circuit lug or a connecting part of an electronic component, etc.
  • the other portion of the contact piece 1, not described or shown here can be any what type known for this kind of contact piece, and can understand by a portion in which a wire can be crimped, screwed or welded, or a fixing portion on a connector or a printed circuit board or a second portion of the female type to constitute a piece of transition contact, etc.
  • the portion of the room of contact which interests us here consists of an axial drilling of a end of the contact piece followed by the realization of radial slots on a portion of the length of the tubular portion made by this piercing, to form resilient tongues. These tabs are then clamped together to form an elastic clip.
  • This construction has many disadvantages, ie a risk of permanent deformation of one or more tongues in the case insertion of a male element or introduction of a male element of too large diameter. Plus, although the contact piece consists of only one part, it is expensive because the necessary material must possess both the electrical qualities that necessary for its operation.
  • a first improvement to the contact piece above consists of covering the portion in question with a socket, as see in Figures 1A, 1B and 1C.
  • Figures 1A, 1B and 1C show the contact piece 1, consisting essentially of a metal rod, one end visible in the figure is intended to receive a male element, not visible on the figures.
  • the other end of the contact piece, not visible on the figures, is machined in a conventional way to fulfill a function any known of such a portion of contact piece.
  • the portion of the contact piece 1 that interests us here was breakthrough axially, so as to form a housing 10 in which will come to lodge the male element. Slots 11, three in the form shown here, have been machined to separate three tabs 12.
  • this construction represents the first construction described previously.
  • this portion is provided with the contact piece of a sleeve 2 of tubular form, fixed by crimping or any other means on a portion of the contact piece 1 behind the 12. This bushing 2 stops against the outer surfaces of the tongues 12, preventing too much spacing of the latter.
  • the end of the socket 2 turned towards the opening of the housing 10, comprises an end wall 20 provided with a through hole 21 coaxial with the longitudinal axis of the contact part 1, respectively of the 10.
  • the diameter of this hole 21 is determined so as not to let pass that a male element having a diameter smaller than that of a male element which would press the tongues 12 against the socket 2.
  • the hole 21 coaxial with the longitudinal axis of the housing 10 makes in addition to serving as a means of guiding the male element during its introduction.
  • Figure 2 shows a construction planned to eliminate these last defects.
  • a contact piece 1 whose the end that interests us here is provided with an axial drilling forming a housing 10 for the male element to receive.
  • a contact clip 3 is chased inside the housing 10.
  • the contact clip 3 is formed from a metal ribbon, of width corresponding to the length of the clip, which is stamped to form a lateral band with several tabs of substantially trapezoidal shape projecting from one of the sides of the sideband, the large bases of each tongue being adjacent to the sideband while the small bases are free.
  • the strip is cut into portions, each with several tabs trapezoidal the length of the portion corresponding to the perimeter inside the housing 10.
  • the tape portion is then rolled, the tongues are then tightened by their ends to deform them and to decrease the diameter inscribed between the free ends of the tongues.
  • the clip 3 thus formed is driven into the housing 10, the free ends of the tongues 30 being directed towards the bottom of the housing 10; portion 31 of clip 3, formed by the sideband described above is maintained towards the open end of the housing 10 by any known means, chase, crimping or other.
  • the clip 3 only the clip 3 must be constructed in one alloy having excellent conductive qualities as well as excellent mechanical qualities of spring effect. It follows that the rest of the room contact 1 can be machined in a cheaper metal or alloy, by example of brass.
  • the clip 3 will preferably be made from a bronze / beryllium alloy or other.
  • the tongues 30 When introducing a male element, the tongues 30 deviate to enclose said male element.
  • the spacing movement tabs 30 is also limited here by the inner wall of the housing 10, with the same disadvantages as mentioned above.
  • the end open housing 10 includes a first cylindrical scope inner 100, whose inside diameter is greater than that of the dwelling 10, followed by a second inner cylindrical bearing surface 101 whose inner diameter is between range 100 and bottom housing 10.
  • a contact clip 4 is driven by the open end of the housing 10, so that its cylindrical portion 40 comes to position on the inner cylindrical bearing surface 101.
  • the clip 4 is preferably obtained in a manner similar to that which was previously described for the clip 3. An operation complementary outward arching ends of the tabs is performed when clips are always assembled into a strip keep on going.
  • the trapezoidal slats described it is possible to also have slats of rectangular shape and separation slots Trapezoidal shape.
  • the clip 4 is fixed, by driving, crimping or any other means known on this inner bearing 101. Contrary to what has been described above concerning the clip 3, the contact tabs 41 of the clip 4 have their free ends 410 turned towards the opening of the housing 10. From the more these free ends 410, for each of the tongues 41, are formed so as to have an arcuate end portion 411, the end free movement outwards from the longitudinal axis of the dwelling 10.
  • This device is completed with an outer sleeve 5 driven away and fixed on an outer cylindrical bearing surface 102 of the contact piece 1.
  • the end of the sleeve 5 turned towards the opening of the housing 10, comprises a wall end 50 provided with a through hole 51 coaxial with the longitudinal axis of the contact part 1, respectively of the housing 10.
  • This hole 51 is determined so as to pass only one male element of diameter acceptable by the contact clip 4. It can also be seen on the figure, that if a male element has been introduced into the clip 4, its diameter being smaller than the diameter of the hole 51, the spacing movement of tabs 41 of the clip 4 is never limited by the inner diameter of the range 100, because it is greater than that of the range 101, nor by the diameter inside the bushing 5, since it is dimensioned so as to allow a maximum spacing tabs 41.
  • the piece corresponding contact point comprises a contact clip 4 whose tongues 41 undergo a deformation only elastic, over all their length and throughout their deformation range, the limitation in diameter of the male element being provided by the calibrated hole 51 of the 5.
  • This mode of operation in elastic mode ensures a electrical conductivity of the maximum contact, even in case of vibrations.
  • each of the tabs makes relative to the axis longitudinal is also of low value; this angle is typically understood between 4 ° and 10 °, being preferably between 6 ° and 8 °. Given the portion 411 arcuate ends of the tongues 41, we can not have arcboutement of the male element during its introduction or withdrawal between the tabs 41.
  • This arcuate portion is a better transmission of the mechanical forces between the male element and the clip, especially in the presence of vibrations. Indeed, he was observed a damage to the contact surface of the male element in case of vibrations when the ends of the contact tongues have a edge rather than rounding as described for this embodiment.
  • Another advantage of this device is that the distance of introducing the male element before contact is established is very weak since the male element first meets the weak portion diameter of the clip 4 formed by the tabs 41 close together.
  • hole 51 aligned with the free ends 410 of the tongues 41 form a guide in two points of the male element being introduced, preventing a crooked introduction.
  • Contact piece 1 with the exception of clip 4, will be manufactured in a low cost metal or alloy, for example brass or more particularly brass capable of supporting the crimping of a driver in the portion of the contact piece 1 opposite to that described in detail upper.
  • the clip 4 will preferably be made of an alloy of bronze and berylium.
