Patent number: 10251285Abstract: A second seal material is coated on an annular seal surface constituted by a partition wall of a connector housing and a three-sided outer peripheral surface of a cover, and is joined with an annular base outer peripheral surface on the base, and the cover and the base are integrated with fastening screws at the four corners, and hold the three sides of a circuit board therebetween. Fastening surfaces of the base are embossed with a first depth so that bending strength is reinforced whereby a stable seal gap is generated, and corner outer walls and a connection outer wall are disposed at four corners and one side of the cover, so as to generate a retention gap to prevent outflow of the second seal material.Type: GrantFiled: December 15, 2017Date of Patent: April 2, 2019Assignee: Mitsubishi Electric CorporationInventor: Nobuaki Nuriya

Patent number: 9730349Abstract: Upon disposing the connector housing, thinning of the waterproof sealing material due to scraping is compensated by a replenishing end section of waterproof sealing material that is applied to the replenishing inclined surface sections. As a result, sealing performance is improved while allowing for a simple mold construction of the connector housing and the cover without the need for auxiliary seal grooves.Type: GrantFiled: April 18, 2016Date of Patent: August 8, 2017Assignee: Mitsubishi Electric CorporationInventors: Nobuaki Nuriya, Mitsunori Nishida

Patent number: 9661772Abstract: In a waterproof control unit in which a part of a connector housing mounted on a circuit board is exposed and the circuit board is hermetically housed in a casing including a base and a cover, a sealing gap between the cover and the connector housing is defined between fitting surfaces of a first concave thread and a first convex thread, and a waterproof sealing material is applied to the sealing gap. A waterproof sealing material is applied to the latter sealing gap. Each of the sealing gaps extends inward and outward across an inner boundary surface of a partition wall of the connector housing. Plane movement of each of the sealing gaps is restricted by side-surface convex threads and side-surface concave threads.Type: GrantFiled: April 20, 2015Date of Patent: May 23, 2017Assignee: Mitsubishi Electric CorporationInventors: Nobuaki Nuriya, Mitsunori Nishida
