Patent number: 8641438Abstract: In an electronic device, a slider is disposed in an insertion opening of a housing of a card edge connector. The slider is movable with an insertion operation of a circuit board into the insertion opening from an initial position before the circuit board is inserted to an insertion completed position where the insertion operation of the circuit board is completed by being pushed by the circuit board. When the slider is at the initial position, terminal projections are supported on a support surface of the slider in a resiliently deformed condition so that contacts are separated from an electrode-formed surface of the circuit board. When the slider is at the insertion completed position, the terminal projections are completely separated from the slider and in a state of applying a spring back force of resilient deformation to the circuit board through the contacts.Type: GrantFiled: February 23, 2012Date of Patent: February 4, 2014Assignee: Denso CorporationInventors: Takashi Kamiya, Taku Iida, Yuji Watanabe

Patent number: 6341066Abstract: In an electronic control unit, a drive element liable to generate heat and a control processing element liable to be affected by heat are respectively mounted on a drive circuit board and a control circuit board different from each other, and the two boards are connected to each other by a flexible printed circuit board. The bonding portion of the flexible printed circuit board to the control circuit board is a back side portion of a connector mounted on the control circuit board at the same side as the control processing element. Therefore, heat generated by the drive element is suppressed from being transferred to the control processing element without causing layout hindrances.Type: GrantFiled: September 29, 2000Date of Patent: January 22, 2002Assignee: Denso CorporationInventors: Toru Murowaki, Toshiaki Yagura, Yoshitaka Nakano, Taku Iida
