Definitions

  • the invention relates to a miniature connector for shielded flat cable more particularly intended for flat cables comprising a stack of three conductors, one of which is a high-voltage conductor and the other two are low-voltage equipotential conductors.
  • these types of connectors are not morphologically suitable for armored flat cables constituted by a stack of three conductors.
  • the Applicant has therefore posed the problem of producing connectors of the smallest possible size which provide both contact recovery without mechanical or thermal damage to the conductive tracks of this type of cable or their insulating support.
  • the Applicant has designed a connector which does not have the drawbacks mentioned above and which furthermore has the required dielectric qualities, making it suitable for transferring significant impulse energy.
  • this energy is of the order of a duration of 1 ⁇ s at a voltage of around 3,500 V with a flow rate approaching a thousand amps and this whatever the pressure, the conductor being perfectly sealed against the air.
  • the present invention more particularly relates to a male contact member connected to a shielded flat cable of the type comprising a stack of three conductors, a high voltage conductor and two low voltage equipotential conductors, characterized in that it comprises - an electrically conductive male contact at the end of the high voltage conductor, - a fork made of shape memory material capable of trapping the high-voltage conductor, - a ring of oblong section in shape memory material ensuring on the one hand the junction and the equipotentiality of the low voltage conductors of the cable; and secondly the continuity of mass transfer to the mass of an organ to which it can be connected.
  • a male contact member characterized in that it further comprises an insulating element giving this male member good mechanical strength and desired dielectric characteristics.
  • a female contact member connected to a coaxial cable comprising: - a female central contact forming an electrically conductive elastic clamp connected on the coaxial cable side to the high voltage central conductor of the cable, - an insulating and elastic body surrounding the central female contact, capable of providing electrical insulation and sealing - a mass recovery device by transfer at the end of the insulating body.
  • the female contact member further comprises a locking device ensuring the retention of a male member capable of being connected to the female member.
  • the high voltage male contact consists of an electrically conductive part and of cylindrical shape.
  • the ring of oblong section provides the junction and the equipotentiality of the two low voltage conductors of the cable by pinching on the latter of the narrow part of this ring.
  • the mass transfer continuity towards the mass of the female member is achieved by means of two bosses, for example of square section located on the ring of oblong section made of shape memory alloy. .
  • the insulating element consists of an insulating resin which adheres perfectly to the male plug thus obtained.
  • the male plug also has two bevelled fields which, when penetrating into the female organ, compress the insulating body of this female member, thus ensuring a seal, in particular in the air, through and to the coupling during the insertion of the male plug.
  • the mass recovery device consists of two flexible metal blades coming into contact with the two bosses of the male plug.
  • the locking device consists on the one hand of two ceramic balls placed in the female member and, on the other hand, of two housings placed in the male plug, these balls being trapped in these housings and maintained pressed by an outer ring retained by a spring.
  • the connector consists of two complementary members.
  • the member attached to the flat cable 30 is designated by male plug and bears the reference 1.
  • the female member 100 may be in the form of either a base fixed to a panel, or an extension. It is this female member which, according to the invention, comprises the locking elements so as to obtain a male plug with the smallest possible cross-section.
  • the female member 100 is intended to receive a cable 102, of the coaxial type for example, and comprises at its termination on the coaxial cable side a cable gland 101 which fixes this cable in this member.
  • the shielded flat cable 30 is housed in the male plug 1.
  • the shielded flat cable comprises, as will be described more precisely with reference to FIGS. 6 and 7, a central high-voltage conductor and two equipotential low-voltage conductors.
  • the high voltage central conductor is connected to an electrically conductive male contact 10 of the male plug.
  • the low-voltage conductors are connected to a mass recovery device consisting of two metal blades 23 arranged in the female element 100.
  • the male contact 10 of electrically conductive material is pinched by an electrically conductive fork constituting the female contact 20, located on the base 21.
  • the female member 100 also includes a locking device 24, 25, 26 ensuring: the retention of the male plug 1 in the female element 100 in all cases of constraint, environment, missile for example, - a visual check to ensure that the plug is correctly inserted by means of a color mark 27.
  • This locking device consists of two ceramic balls 24, for example, trapped in the rectangular cross-section end of the base, held pressed in two housings 38 located on the male plug 1, by an outer ring 26 held in place by a spring 25.
  • Figure 2 shows the cable 102 before mounting in part 2 of the female base.
  • the cable is stripped, the stripped part being brazed, for example, inside the female part 2.
  • the plug 1 viewed in longitudinal section. This figure makes it possible to detail all the elements constituting this file.
  • the male contact 10 preferably has a cylindrical shape and extends inside the plug, that is to say on the flat cable side 30, by a fork 11 made of shape memory alloy.
  • the two low voltage tracks 32 and 33 of the flat cable are joined by means of a ring 37 of oblong section, made of shape memory alloy.
  • This ring 37 ensures the following functions: - a junction and the equipotentiality of the two low voltage tracks 32 and 33 of the flat cable by pinching on the latter of the narrow part 36 of the ring with oblong section in shape memory alloy, the continuity of mass transfer towards the mass of the female element 100 by means of two bosses 35 located on this ring, the bosses having for example a square section.
  • the flat cable 30 thus equipped is coated with an insulating material 3, for example a resin, which adheres perfectly (Eccobond 45 or similar product), giving the male plug on the one hand good mechanical strength and, on the other hand , guaranteeing it the desired dielectric characteristics.
  • an insulating material 3 for example a resin, which adheres perfectly (Eccobond 45 or similar product), giving the male plug on the one hand good mechanical strength and, on the other hand , guaranteeing it the desired dielectric characteristics.
  • the oblong section ring 37 has been shown in perspective in FIG. 4. This ring therefore comprises a part having a pinch 36 and another part having the bosses 35.
  • FIG. 5 represents a cross section of the male plug at the level of the pinched part of the ring 37. This FIG. 5 therefore makes it possible to highlight the pinching function of the ring 37 ensuring the junction and the equipotentiality of the two low voltage tracks flat cable 30.
  • Figures 6 and 7 illustrate the layered structure of the shielded flat cable 30. Indeed, Figure 6 shows the shielded flat cable seen in longitudinal section.
  • the high voltage conductor 31 is located between two layers of insulator 34, on which the low voltage conductors 32 and 33 are placed respectively.
  • FIG. 7 illustrates the shielded flat cable 30 after stripping the end of the conductors for fitting inside the plug 1.
  • FIG. 8 shows the male plug as a whole, a part of this plug having been partially released in order to show the location of the ring 37 inside this plug.
  • housings 38 intended to receive the balls 24 which are located in the locking device of the female member.
  • this female member 100 further comprises an elastic insulating body 22, for example an elastomer (silicone or equivalent) of suitable section.
  • the seal at the crossing and at the coupling is ensured during the insertion of the male plug 1.
  • the latter in fact has two bevelled fields 39 which, when penetrating into the base 21, compress the elastomer 22, itself made with adequate form.
  • the lateral stress experienced by the elastomer 22 is distributed over the upper and lower surfaces of the male plug, thus ensuring intimate contact of the elastomer over the entire periphery of the male plug.
