Patent number: 8535074Abstract: Occurrence of defective electrical connection caused by dust that has entered the interior through a corresponding insertion hole can be prevented well by a simple configuration. A through hole facing a corresponding insertion hole is formed to penetrate through a movable contact attached to an insulating housing, and two corresponding connector contact pieces are disposed respectively in both sides sandwiching the through hole. Thus, the dust that has entered the interior through the corresponding insertion hole opened when a corresponding connector is not mated is configured to be discharged through the through hole without accumulating the dust on the movable contact to reduce the risk that the electrical conductivity between the movable contact and the fixed contact may be disturbed by the dust.Type: GrantFiled: April 25, 2012Date of Patent: September 17, 2013Assignee: Dai-Ichi Seiko Co.Inventors: Takeshi Hirakawa, Kenichi Yotsutani
