Definitions

  • the invention relates to a connector assembly, comprising first and second connectors intended to mate with each other, for instance intended to be used in the automotive industry.
  • a connector assembly is used for the transmission of signals (e.g. electrical or optical) between two components.
  • a general concern in the field of connectors is to ensure that the connectors are properly mated, so that the two components are properly connected for information or power exchange.
  • This concern is especially acute for automotive connectors in which the connectors have to be perfectly mated since they are subjected to high vibration environment; a faulty assembly process may produce high risks from safety standpoint.
  • connection position assurance member able to move with respect to its insulating housing along a rear/front direction, from a rear position of the CPA member towards a front position of the CPA member.
  • the CPA member usually comprises a CPA pawl with a finger portion, which, when the first and second electrical connectors are not mated, is intended to be stopped by a stop before reaching the front position.
  • the finger portion is designed in such a way that it is adapted to be cleared (by deflection) from the stop by a member carried by the complementary connector.
  • An object of the invention is to provide an electrical connector assembly with a CPA member having a CPA pawl with an increased life time. Accordingly, there is provided an electrical connector assembly as claimed in the appended claim 1.
  • the CPA pawl can be released when the CPA member is in the front position, so that the stress is reduced or cancelled, which leads to an increased life time for the CPA pawl.
  • FIG. 1 is a longitudinal cross section view of a first embodiment of the electrical connector assembly according to the invention, with the electrical connectors unmated,
  • figure 2 is a longitudinal cross section view of the electrical connector assembly of figure 1 , with the electrical connectors in the process of being mated,
  • figure 3 is a perspective cross section view corresponding to the view of figure 2
  • figure 4 is a longitudinal cross section view of the electrical connector assembly of figure 1 , with the electrical connectors mated and the CPA in its rear position,
  • figure 5 is a longitudinal cross section view of the electrical connector assembly of figure 1 , with the electrical connectors mated, and the CPA in its front position,
  • FIG. 6 is a longitudinal cross section view of a second embodiment of the electrical connector assembly according to the invention, with the electrical connectors mated and the CPA member in the process of being moved from the rear position to the front position,
  • figure 7 is a longitudinal cross section view of electrical connector assembly of figure 6, with the CPA member in the front position.
  • the assembly 100 comprises first and second electrical connectors 102, 104.
  • the first and second connectors 102, 104 are intended to mate with each other along a rear/front direction RF, orientated from the second connector 104 towards the first connector 102.
  • orientation terms will refer to the direction RF.
  • terms such as “front” will refer to the side along the direction RF towards the first connector 102
  • terms such as “rear” will refer to the side along the direction RF towards the second connector 104.
  • terms such as “up” and “down” will refer to a deflection direction D, which will be explained later, transverse to the direction RF.
  • the first electrical connector 102 comprises a first insulating housing 106 comprising a first skirt 108 projecting rearwards along the direction RF and delimitating a first aperture 110.
  • the housing 106 further carries a first locking stop 112 and an auxiliary stop 114, both projecting upwardly from the first skirt 108.
  • the auxiliary stop 114 is located at a distance in front of the first locking stop 112.
  • the first locking stop comprises a rear slanted face 115.
  • the second connector 104 comprises a second insulating housing 116 comprising a second skirt 118 projecting frontwards along the direction RF and delimitating a second aperture 120, intended to receive the first skirt 108 of the first electrical connector 102.
  • the second housing 1 16 further comprises a terminal accommodation casing 122 located inside the second aperture 120 and intended to be received in the first aperture 110.
  • the second housing 116 is further provided with a locking pawl 124 extending frontwards along the direction RF.
  • the locking pawl 124 carries a second locking stop 126 intended to come in between the first locking stop 112 and the auxiliary stop 114 when the connectors 102, 104 are mated, so as to cooperate with the first locking stop 112 for locking the connectors 102, 104 ( Figure 4).
  • the second locking stop 126 comprises a top slanted face 127 and a rear stopping face 129.
  • the second connector 104 further comprises a CPA member 128 mounted on the second housing 116 and able to move with respect to the second housing 116 along the direction D, from a rear position illustrated on figure 1 , towards a front position illustrated on figure 5.
  • the CPA member 128 comprises a CPA pawl 130 extending frontwards along the direction RF.
  • the CPA pawl 130 comprises a finger 132 located at a front end of the CPA pawl 130 and projecting downwardly.
  • the finger 132 acts both as a stop portion and an activation portion.
  • the finger 132 acts as a stop portion and is stopped by the stopping face 129 of the second locking stop 126, before the CPA member 128 reaches the front position ( Figures 1 and 2). In this way, the CPA member 128 is prevented from reaching the front position, so as to detect a wrong mating of the connectors 102, 104.
  • the finger 132 acts as an activating portion and cooperates first with the slanted face 115 of first locking stop 112, so as to deflect the CPA pawl 130 over a first deflection distance d1 in a deflection direction D transverse to the direction RF, and to shift the stop portion (finger 132) with respect to the second locking stop 126.
  • the stop portion (finger 132) does not abut the stopping face 129 so that the CPA member is allowed to move towards the front position.
  • the activating portion (finger 132) then interacts with and slips over the top slanted face 127 of the second locking stop 126, so as to deflect the CPA pawl 130 over a second deflection distance d2 in the deflection direction, so as to shift the stop portion (finger 132) with respect to the auxiliary stop 114. In this way, the stop portion (finger 132) does not abut the auxiliary stop 114 and allows the CPA member to move towards the front position.
  • the CPA pawl 130 further comprises a recess area 134 (See fig. 5) located, with respect to the direction D, behind the stop portion (finger 132).
  • the recess area 134 is intended to receive, when the CPA member is in the front position, the first locking stop 112 and the auxiliary stop ( Figure 5), so as to allow a release of the CPA pawl 130 over a release distance d R in a release direction R opposite the deflection direction D.
  • the release distance dR is of at least 50% of the deflection distance d1+d2 and still preferably of at least 90% of the deflection distance d1+d2.
  • the CPA pawl is able to return close to its initial position (which is a rest position in the described example).
  • the CPA pawl 130 leans on the auxiliary stop 1 14.
  • a second electrical connector assembly 200 is illustrated.
  • the second assembly 200 differs from the first assembly 100 mainly by the fact that there is no auxiliary stop, and by the fact that the stop portion is formed by a front end 202 of the CPA pawl 130, while the activating portion is formed by a finger 204 projecting downwardly from the CPA pawl 130 and located at a distance behind the front end 202. Furthermore, the recess 134 is located between the front end 202 and the finger 204.
