Patent number: 9385468Abstract: The invention relates to a joint connector assembly including first and second connectors connected to each other by a circuit board and connected to third connectors by connection terminals. The circuit board is mounted at the center of the third connectors below the first and second connectors located in an upper region of a main body housing and is integrally formed with the main body housing in a lower region thereof. The upper region of the main body housing defines first and second connector receptacles for the first and second connectors. A cover member is attached to a lower surface of the circuit board to cover the circuit board. The joint connector assembly has a reduced volume because the connectors are connected to one another without lines and all the connectors are inserted in the main body housing, allowing the joint connector assembly to be installed in a small space.Type: GrantFiled: August 3, 2012Date of Patent: July 5, 2016Assignee: Tyco Electronics Amp Korea Ltd.Inventor: Chul-Sub Lee
