Definitions

  • the invention relates to an electrical connector and, more particularly, to terminal position assurance in an electrical connector.
  • an electrical connector housing assembly comprising an electrical connector housing having electrical terminal receiving areas; and a terminal position assurance (TPA) member movably mounted to the electrical connector housing.
  • the TPA member comprises a latching lever for holding the TPA member at a pre-lock position, wherein the latching lever comprises a first end adapted to be moved by a user, a middle section on a fulcrum of the electrical connector housing, and a second end latched with the electrical connector housing.
  • the latching lever holds the TPA member in the pre-lock position on the electrical connector housing until fulcrum pivoted on the fulcrum of the electrical connector housing to an un-latched position by the user.
  • a terminal position assurance (TPA) member comprising at least one projection adapted to engage at least one deflectable terminal latch of an electrical connector housing to prevent the terminal latch from deflecting; and at least one latching leyer for holding the TPA member at a pre-lock position on the electrical connector housing.
  • the latching lever is formed by two rearward extending outer slots and two forward extending inner slots.
  • Fig. 10 is an enlarged sectional view of portions of the main housing member and the TPA member as shown in Fig. 6 with the TPA member moved to its lock position;
  • FIG. 2-4 there is shown an electrical connector 40 incorporating features of the invention.
  • the electrical connector 40 is intended to replace or be used instead of the first electrical connector 16.
  • the electrical connector 40 is adapted to be connected to the first group 12 of electrical conductors and be removably connected to the second electrical connector 18.
  • the electrical connector 40 comprises a housing 42 and electrical contacts 44.
  • the electrical contacts 44 are not shown in Figs. 3 and 4 merely for the sake of clarity.
  • the main housing member 46 comprises contact receiving areas 56.
  • the electrical contacts or terminals 44 are located in the contact receiving areas 56.
  • the front end of the main housing member 46 comprises apertures 58 into the contact receiving areas 56.
  • the apertures 58 are adapted to allow insertion of the male contacts 26 into the contact receiving areas 56 and into mating electrical connection with the electrical contacts 44.
  • the electrical conductors 13 are adapted to extend through apertures 60 of the seal retainer 48 and into the contact receiving areas 56 where they are connected to the electrical contacts 44.
  • the rear seal 50 is adapted to seal the rear end of the contact receiving areas 56 at the rear end of the main housing member 46 where the electrical conductors 13 pass into the rear end of the main housing member 46.
  • the housing 46 forms a center section 64 surrounded by the receiving area 54.
  • the center section 64 defines the contact receiving areas 56.
  • the contact receiving areas 56 are aligned in two rows.
  • any suitable array of contact receiving areas could be provided.
  • the opposite lateral sides of the center section 64 each comprise two detents or latch receiving areas 66, 68 and a fulcrum 70.
  • the front area 66 is located rearward from the fulcrum 70.
  • the rear area 68 is located rearward from the front area 66.
  • a ramp 72 is provided between the front and rear areas 66, 68.
  • the projection 76 is adapted to contact the terminal latches 55 to prevent the latches 55 from deflecting.
  • the terminal latches 55 are able to resiliently deflect inward to allow insertion or removal of the terminals 44 in the areas 56.
  • the user might desire to move the TPA member 53 from its lock position to its pre- lock position.
  • the user can pull on the TPA member 53 is a direction reverse to a direction 102.
  • the ramps 72 can allow the rear ends 94 to deflect outward as the TPA member is moved forward by axial only force to allow the projections 98 move back into the front areas 66.
  • the invention can be incorporated into a connector without increasing the size of the connector (for example, the connector 40 can be the same overall size as the connector 16) .
  • the TPA side latches could be made to work without the fulcra on the housing .
