Definitions

  • the present invention relates to a connector device equipped with a connector position assurance (CPA) member and, more particularly, to a connector device equipped with a connector position assurance member capable of reducing the overall size of the connector device.
  • CPA connector position assurance
  • Automobiles are used in a very complex environment in which electrical characteristics, mechanical characteristics, and/or weather irregularly changes. This means that automotive connectors are also used in the same environment. Since connectors are used for electrical connections, the connectors are required to ensure reliable electrical connections and mechanical couplings with other connectors. Among them, in the case of connectors used for safety-related electronic parts such as an airbag, since they are closely associated with driver's safety, it is very important that the electrical connections and mechanical couplings of the connectors must not be released by an improper coupling between a terminal and a housing under any circumstances. Accordingly, when a first connector and a second connector are engaged, a connector position assurance (CPA) device is used to ensure that these connectors are securely and perfectly mated.

  • the second connector 20 is a plug connector connected to a wire W and configured to be inserted into the first connector 10.
  • the connector position assurance device 30 has a connector position assurance (CPA) function.
  • the connector position assurance device 30 includes a sliding member base 31, a main arm 32 protruding from the center of the sliding member base 31, and two support arms 34R and 34L protruding from the respective ends of the sliding member base 31.
  • the main arm 32 comes into contact with a fitting fixing portion (not shown) provided in the second connector 20, thereby being locked.
  • the support arms 34R and 34L are engaged with reverse insertion prevention ribs (not shown) provided inside the second connector 20 and function to guide the sliding of the sliding member base 31.
  • the main arm 32 of the connector position assurance member 30 is engaged with the fitting fixing portion that serves as a locking lever, thereby preventing the first and second connectors 10 and 20 from being accidently disengaged from each other.
  • the connector position assurance member 30 must be first released so that the first and second connectors 10 and 20 can be disengaged. Accordingly, accidental disengagement of the first and second connectors 10 and 20 can be prevented.
  • the connector position assurance member 30 is provided with the support arms 34R and 34L on the respective sides of the sliding member base 31 so that the sliding of the sliding member base 31 cab be guided as described above.
  • This configuration has a problem in that the overall width W1 of the connector position assurance member 30 is increased due to the presence of the support arms 34R and 34L. For this reason, the sizes of the first and second connectors 10 and 20 are increased.
