  • Patent number: 11462963
    Abstract: An electric pump device includes a motor having a rotor and a stator portions, a pump portion and a housing. The stator portion has a stator core, and coils each having a winding portion and a crossover portion. The housing has a housing body portion having a tubular shape and extending in the axial direction, and a flange portion expanding radially outward from the outer peripheral surface of the housing body portion. The flange portion has an end surface that faces toward one side in the axial direction and is disposed in the axial direction between a first and a second virtual plane. The first and the second virtual planes pass through parts of the stator core, the winding portion, and the crossover portion located respectively closest to one and the other sides in the axial direction and expanding in a direction perpendicular to a central axis.

  • Patent number: 10511107
    Abstract: A connector that can connect electronic parts in different shapes and sizes. The connector includes a body part, a first connection part, and a second connection part. The body part is attached to a socket. The first connection part and the second connection part are arranged side by side along a first direction and connected to the body part respectively. The first connection part has a first contact part and a second contact part that are disposed opposite to each other with a gap in a second direction. The second connection part has a third contact part and a fourth contact part that are disposed opposite to each other with a gap in the second direction. A shortest distance between the first contact part and the second contact part is set greater than a shortest distance between the third contact part and the fourth contact part.

  • Patent number: 9819121
    Abstract: A screwless terminal block allows easy insertion and removal of a wire. A housing (2) includes a fixture insertion opening (23) through which a rod-like fixture (6) is inserted to come in contact with a contact pressure spring (4) and deform the spring (4) away from a wire (5). When the fixture (6) is inserted through the fixture insertion opening (23), an acute angle of 45° or less is formed by an axis of the fixture (6) and a straight line connecting a contact point A between the housing (2) and a part of the fixture (6) adjacent to the wire insertion opening (24) and a contact point B between the housing (2) and a part of the fixture (6) adjacent to the spring (4) at a cross-section taken along a plane including the axis of the fixture (6) and parallel to a pressing direction of the spring (4).

  • Patent number: 9799979
    Abstract: A socket includes a base and a connection fitting including a bracket and a spring member and assembled to an upper surface of the base. The spring member of the connection fitting is pressed and elastically deformed to sandwich a lead between the bracket and the spring member. A position restricting protrusion configured to come into contact with the pressed and deformed spring member and prevent plastic deformation is protruded on the upper surface of the base.

  • Patent number: 9774107
    Abstract: A socket includes: a base; a connection fitting including a bracket and a spring member, configured to form pressure springs by dividing the spring member into two in a width direction by a slit provided to the spring member, and assembled to an upper surface of the base; and a case cover configured to fit to the base and to cover the connection fitting. The pressure springs of the spring member are pressed and elastically deformed by an operation driver inserted through an operation hole provided to the case cover, to sandwich between the bracket and the pressure springs a lead inserted through an insertion hole provided to the case cover. A guide partition wall configured to engage with the slit of the spring member is integrally molded with an inner surface of the case cover.
