Definitions

  • the present invention relates to mating detection devices for connectors, and connectors comprising such mating detection devices.
  • Some of these assemblies included mechanical means, sometimes with audible markers or with so-called connector position assurance (CPA) elements, that were only able to be mechanically activated until a connector assembly was fully connected, for example by clicking or sliding into place.
  • CPA connector position assurance
  • the present invention has notably for object to provide a simple and more reliable mating detection device.
  • the mating detection device is wholly dependant on the mechanical locking elements of the connector itself.
  • the mating can only be detected after the connectors are mechanically coupled. Therefore it can only indicate a pair of locked connectors if the connectors are mechanically locked, ensuring that the mating detection device cannot indicate a false mating.
  • the whole functionality of mating detection may be found on a single device or on a single connector of the connector pair when the device is applied to a conventional connector
  • Figures Ia to Ic are perspective views of a first embodiment of the mating detection device

  • the electrical member 7 is a Printed Circuit Board conferring a certain resiliency permitting it to flex in the vertical (Z) direction in the void 6a defined between the two forks 6.
  • the first electrical member 7 is an integral surface of the housing 3 of the mating detection device.
  • An electrical mating detection loop 8 is integrated to the electrical member (fig 2), and has a pair of electrical tracks 9 etched on the inner surface 7a of the electrical member 7.
  • the mating detection loop is open when the connector is not mated with a counterpart.
  • the tracks 9 are terminated by open ended terminals 10 to form an open circuit.
  • the terminals 10 are disposed on the forward portion of the electrical member 7 able to flex.
  • the tracks 9 may alternatively be printed on the electrical member 7 using electrically conductive ink, or may constitute metallic tracks adhered to the electrical member 7.
  • a longitudinally extending, resilient, electrically conductive member such as a tongue 11 is fixed by adhesion or overmolding to a bridging portion 12 of the housing 2.
  • the bridging portion 12 extends between the two legs 5 and also supports the inner surface 7a of the board 7.
  • the resilient tongue 11 is positioned so that its enlarged free end 11a of the tongue is adapted to contact both terminals 10 under bending, in such a way as to provide electrical contact from one terminal to the other by intermediary of the tongue 11.
  • the resilient member 11 is made of an electrically conductive material or is made of a non-conductive material, and wherein at least a portion 11a of said resilient member coming into contact with the conductive terminals presents an electrically conductive surface.
  • Figure 2 illustrates an alternate embodiment of the mating detection device 1. The device is illustrated in an exploded representation of a top part 13a rotated by 180° about imaginary axis Xi to be illustrated removed from the bottom part 13b. Analogously to the electrical member 7 protruding freely between the two forks 6 of the housing 2 as illustrated on figures Ia-Ic, the top part 13a incorporates a forwardly protruding lip 13c delimitated by a pair of lateral cutouts 13d. The lip 13c is resilient to movement.

  • the resilient part 13b is preferably, although not necessarily, electrically non- conductive .
  • the end tip 17a of the tongue 17 is coated with a conductive coating such that it may come into contact and bridge terminals 10 in order to close the mating detection loop 8.
  • the mating detection device 1 body may be preferably molded of a synthetic material such as plastic.
  • a resilient tongue 11, 17, is able to be resiliently bent to come into contact with the two terminals 10 of the mating detection loop 8 in order to change the state (open/closed) of the loop 8, thereby signifying a mating state of the connectors.
  • Figure 3 illustrates a perspective view of a typical conventional connector, which may be used in conjunction with the mating detection device 1.
  • the connector 20 comprises a front end 21 for mating with a complementary connector (not shown) , and means for locking 22 the connector 20 to the complementary connector.
  • the locking means or features 22 comprises a pair of resilient lever arms 24 connected together at their extremity with a joining portion (or latch portion) 25 (see Figure 5) designed to cooperate with a lug on a corresponding mating connector.
  • the lever arms 24 are further connected together by a ledge 23 for user activation to lift and release the latch 25 from a locked position.
  • Figures 4 and 5 illustrate the connector 20 fitted with the mating detection device 1.
  • Fixation portions 5a of the legs 5 of the mating detection device cooperate with catches 26 on the connector to be fixed thereon.

  • figures 8b and 8c illustrate intermediate mating steps
  • figure 8d illustrates the pair of connectors positively mated with each other.
  • the tongue 11 will eventually, in turn, also be solicited to ride over the lug 31. This is illustrated in figure 8c. In this position, the tongue will be once again returned to its nested position between the latch arms 24, and safely spaced from the electrical member 7 by virtue of the latch arms 24 supporting the electrical member 7, thus preventing the latch arm 11 from contacting it.
  • the latching arms 24 will continue to keep the electrical member 7 upwardly solicited until the latch 25 is able to resiliently fall back such that the latch 25 is longitudinally blocked behind the lug 31 (Fig. 8d) .
