Patent number: 8469752Abstract: The present invention relates to an electrical connector having a shorting bar and an operation device for controlling the shorting bar. The connector has a housing and electrical conductive terminals disposed in the housing. One or more metal shorting bars are attached to the housing, each shorting bar electrically connects two or more terminals as a protective measure to the systems connected to these terminals before the connector is connected to a counterpart connector. The operation device is movably disposed inside the housing. During the connecting process, the operation device is pushed by the counterpart connector to move relative to the housing towards the shorting bar. Upon completion of the connecting process, a portion of the operation device is inserted between the shorting bars and the terminals whereby the shorting bar are electrically isolated from the terminals to resume the original functions of these terminals.Type: GrantFiled: July 20, 2010Date of Patent: June 25, 2013Assignee: Delphi International Operations Luxembourg, S.AR.LInventor: Joo Hyun Park

Patent number: 8297992Abstract: An electrical connector assembly includes first and second connectors connectable to each other. The first connector has a first housing and a locking lever detachably and movably coupled thereto. The second connector has a second housing and a pair of protuberances formed on external surface of the second housing. When the locking lever is at an open position, first and second connectors are ready to be connected together. When the locking lever moves away from the open position towards a close position, the first and second connectors are guided by the locking lever to connect together and are prevented from being separated. A pair of stoppers are formed on the locking lever which engages the first housing to lock the lever at the open position. When the second connector is inserted into the first connector, the stoppers are released to allow the locking lever to move towards the close position.Type: GrantFiled: September 18, 2009Date of Patent: October 30, 2012Assignee: FCI Automotive HoldingInventor: Joo Hyun Park

Patent number: 8272895Abstract: A sealed electrical connector includes a housing having a terminal-fixing portion, a mating portion for connecting to a counterpart connector and a partition wall therebetween. Contact terminals are fixed into a terminal holder with contact portions protruding out of the terminal holder. The terminal holder is disposed in the terminal-fixing portion. A grommet is placed between the terminal holder and the partition wall. The contact portions extend to the mating portion through the partition wall and the grommet. Molten resin is injected into the terminal holder and fix and seal the contact terminals in the terminal holder. The grommet prevents the resin from leaking into the mating portion through the partition wall. Each contact terminal has a support bracket fixed thereon which supports the terminal in the terminal holder before resin injection. The support bracket allows contact terminals of difference dimension to be fitted and sealed in the housing.Type: GrantFiled: November 9, 2009Date of Patent: September 25, 2012Assignee: FCI Automotive HoldingInventor: Joo Hyun Park

Patent number: 7909638Abstract: An electrical connector assembly includes a first and a second connectors to be mated together, and a Connector Position Assurance (CPA) device installed on one of the first and second connectors. The CPA device is fixed to a pre-lock position when shipped together with said one of the connectors and before the first and second connectors are mated. At the pre-lock position, a locking lever on the second connector can be deformed so that primary locking members of the first and second connectors can be engaged. When the first and second connectors are mated, a rib formed on the first connector acts on a release member provided on the CPA device, to allow the CPA device to move to a final lock position at which, a secondary locking member restricts the movement of the primary locking member of the second connector to prevent the primary locking members from being disengaged.Type: GrantFiled: October 10, 2008Date of Patent: March 22, 2011Assignee: FCIInventors: Ju Won Seo, Joo Hyun Park
