Patent number: 9317077Abstract: An electronic device includes: a first housing 1; a cover 11 capable of covering a portion of the first housing 1 to be covered; and a waterproofing member 12 placed around the portion to be covered. The cover 11 is displaceable between a closed position at which the cover covers the portion to be covered and an open position at which the cover opens the portion to be covered. The cover 11 is in contact with the waterproofing member 12 when it is at the closed position. Even if the number of terminals increases, since the waterproofing member 12 is provided on the first housing 1, the single waterproofing member can render all of the terminals waterproof. Thus, it is possible to reduce the number of components and to reduce the number of assembling steps.Type: GrantFiled: April 2, 2015Date of Patent: April 19, 2016Inventors: Takeshi Mori, Masato Murakata, Masashi Toyota, Jun Sato

Patent number: 8934224Abstract: A casing 1, a lid component 11 for covering a terminal 13 disposed in an opening of the casing 1, and a water sealing component 12 disposed around the terminal 13, are provided. The lid component 11 is structured such that a support portion 11h of a fixing portion 11g is rotatably fixed to the casing 1, and a slidable portion 11b slides relative to a lid portion 11a. Thus, a projection 11c is engaged with a recess 14, and a pair of engagement portions 11f engages with a pair of fixed projections 16. Thus, the lid component 11 engages with the casing 1 in three directions, and is held by being pressed against the water sealing component 12. With this structure, an electronic device having a lid component which can be assuredly locked is obtained.Type: GrantFiled: August 10, 2012Date of Patent: January 13, 2015Assignee: Panasonic CorporationInventors: Akira Iwamoto, Jun Sato, Ryo Yonezawa, Toshiya Senoh, Kenichi Shindo, Masashi Toyota

Patent number: 8811001Abstract: A casing 1, a terminal plate 30 that is exchangeably mountable in an opening 23 formed in the casing 1; and a water sealing component 50 disposed around a terminal 31 formed on the terminal plate 30, are provided. A flange 24 is formed inside the opening 23 so as to surround a center of the opening and project toward the center of the opening. When the terminal plate 30 is mounted on the flange 24, an outer side surface of the terminal plate 30 is flush with a surface 21 of the casing in a portion where the opening is formed. With this structure, an electronic device can be obtained that is reliably waterproof and/or dustproof in a connection terminal portion that is exchangeable so as to enhance an expandability.Type: GrantFiled: August 7, 2012Date of Patent: August 19, 2014Assignee: Panasonic CorporationInventors: Akira Iwamoto, Jun Sato, Ryo Yonezawa, Toshiya Senoh, Kenichi Shindo, Masashi Toyota

Patent number: 8767396Abstract: A main device includes fixing portions that fix a holding device to one principal surface thereof and project from the one principal surface. An extension device includes a placement portion on which the main device is placed and a wall portion on which the placement portion is provided in a standing manner. The wall portion that faces the one principal surface, to which the holding device is fixed, in a parallel relation, has such a shape as to not interfere with the fixing portions that fix the holding device of the main device, when the main device is placed on the placement portion. The main device can be mounted on the extension device with the holding device mounted thereon, and time and effort to remove the holding device can be saved when the main device is mounted on the extension device.Type: GrantFiled: March 23, 2012Date of Patent: July 1, 2014Assignee: Panasonic CorporationInventors: Kenichi Shindo, Jun Sato, Yoshihiro Kawada, Toshiya Senoh, Ryo Yonezawa, Masashi Toyota
