  • the invention relates to a connector that is mateable with a complementary connector and comprises a connector housing, a plurality of terminals and a TPA member for terminal position assurance, and particularly to a connector wherein the terminals are latched in cavities of the connector housing and, when in a fully inserted position, can be locked by the TPA member.
  • Connectors with the terminal position assurance feature are widely used in the automotive sector.
  • Connectors are often delivered in a so-called pre-assembled condition to customers, i.e. the terminals are not fully inserted in the cavities of the connector housing. For final use, it is important that the terminals are fully inserted to be properly seated in their respective cavity formation and that improper seating can be detected easily by the customer.
  • the connector housing is formed with a front housing part and a backward retainer housing part for the several terminals, the latter having engaging fingers situated radially about passages which the terminals extend through.
  • Each terminal has a notch as a seating portion for the engaging fingers of the retainer housing part and a bearing portion of thicker cross section where the engaging fingers are spread apart when the terminals are inserted into the retainer housing part. If a single terminal is not fully inserted into the retainer, the engaging fingers around the respective passage remain spread apart which can be detected when assembling the connector front housing part which acts as a TPA member and has openings fitting around the engaging fingers when the same engage the seating portions of the terminals.
  • the front housing part cannot be properly latched with the retainer housing part.
  • the bearing sections which form beads around the terminals do not allow a small pitch in the arrangement of the terminals, that is, such a connector does not lend itself for miniaturization.
  • Female connectors each with a secondary lock are known from US 4,944,688 and US 4,973,268.
  • the terminals each have a notch wherein latches of the connector housing may engage to fix the terminals in their fully inserted positions.
  • the secondary lock has diamond-shaped pockets formed by diagonal wall sections that can lock the latches, if the terminals are correctly seated. If one of the terminals is not fully inserted, the corresponding latch is deflected and forms a stop for the secondary lock that cannot reach its final position.
  • a complementary male connector may be mechanically coupled to the secondary lock of the female connector where correct electrical mating of the terminals is not ensured when the secondary lock is not fully inserted.
  • a connector having a TPA member is known from EP 0 967 694 A2 and comprises a receptacle connector housing having cantilever latch beams to latch respective terminals in the terminal cavities of the housing, if fully inserted. Otherwise the corresponding latch is flexed outwardly, and the TPA member having support ribs will engage the respective protruding latch and prevent complete insertion of the TPA member. The customer must take care whether this happened, or not, since there is no automatic TPA position detecting means inherent in the construction of the connector. In detail, there is no stop to prevent mechanical coupling of the complementary plug connector on the receptacle connector that has its TPA member not fully inserted. Incomplete insertion of the TPA member will lead to missing contact of the terminals of plug and receptacle connectors.
  • a connector with a locking TPA member according to the preamble of claim 1 is known from WO 2006/034865 Al .
  • the connector housing comprises a contact carrier module having slot-like cavity formations with recesses to accommodate respective terminals, and latching elements for latching the terminals.
  • the TPA member is a cap that has webs in its interior to enter into the slot-like cavity formations of the connector housing so as to lock the terminals. The TPA member can be properly latched on the connector housing, if all terminals are fully inserted in the contact carrier module and are latched by the latching elements.
  • the TPA member In order to detect proper seating of the terminals, the TPA member is provided with a double-armed lever having a stop lever arm, the position thereof depends from the latch-position of the TPA member, if preassembled or final assembled. If one of the terminals is not corrected seated, the TPA member cannot be properly latched in the final position, onto the contact carrier module or connector housing, and the stop lever arm forms a stop that precludes mating of the complementary connector. When all terminals are fully inserted in the connector housing, the stop lever arm of the TPA member can take a depressed position and the TPA member can be latched on the connector housing in the final position, and the connectors can be mated.
  • a further connector with a locking TPA member is known from WO 2006/108610 Al .
  • the connector housing forms slot-like cavities with terminal receiving chambers, each including a pawl for latching behind a stop on the terminal, and a guiding wall with a raising slope for pushing the terminal against the pawl, when the terminal is inserted in the housing.
  • the TPA member is of box-like construction and includes locking lugs for blocking the respective pawls, once the connector is assembled. There is no TPA position detecting means that forms a stop for preventing mating of connectors that are not correctly assembled.
  • a still further connector with a locking TPA member is known from FR 2,866,485 comprising a connector housing and a TPA member.
  • the housing has terminal passages provided with pawls for latching the terminals, and the TPA member has fingers to block the pawls when the connector is completely assembled. No TPA position detecting means is provided.
  • a miniaturized connector comprising a housing with six terminals in two rows, and a cap-shaped retainer with wall portions acting as a TPA member.
  • the retainer has a front wall with six terminal openings and, associated thereto, six jig insertion holes for forcibly resiliently deforming the locking portion of a respective terminal. No probe access opening is provided.
