Mobile battery device, connectable electric equipment, and mobile electric device

A connectable electric equipment comprising an electric equipment that is connectable to a mobile battery device housing a battery and that operates by receiving power of the battery,

• the electric equipment comprising, at a certain place, an electric equipment-side connection part, wherein
• the electric equipment-side connection part is connectable to a battery-side connection part of the mobile battery device,
• the electric equipment-side connection part comprises an electric equipment-side terminal that is electrically connectable via a relay member to a battery-side terminal that serves as an output terminal of the battery of the battery-side connection part, and
• the electric equipment-side connection part comprises:
• an electric equipment-side slip-out prevention part for forming a slip-out prevention structure at a connection portion between the electric equipment-side connection part and the relay member;
• and
• an electric equipment-side water-stop part for forming a water stop structure at the connection portion between the electric equipment-side connection part and the relay member, wherein
• the relay member is a cylindrical member separate from the mobile battery device and the electric equipment,
• the relay member has an inner side surface, an inner threaded part provided on the inner side surface, and an annular-shaped recess formed on an outer surface,
• the annular-shaped recess of the relay member engages with the electric equipment-side slip-out prevention part of the electric equipment,
• a seal member as the electric equipment-side water-stop part abuts with the inner side surface of the relay member to thereby form inside the relay member a water stop structure between the relay member and the electric equipment-side water-stop part, and
• the electric equipment-side connection part is fitted into the relay member to form slip-out prevention by the electric equipment-side slip-out prevention part and water stop by the electric equipment-side water-stop part.

A mobile electric device comprising:

• a mobile battery device comprising a body case having a housing space for housing a battery;
• and
• a connectable electric equipment comprising an electric equipment that is connectable to the mobile battery device and operates by receiving power of the battery, wherein
• the body case of the mobile battery device comprises, at certain places, a battery-side terminal that serves as an output terminal of the battery, and a battery-side connection part,
• the electric equipment of the connectable electric equipment comprises, at a certain place, an electric equipment-side connection part comprising an electric equipment-side terminal that is electrically connectable to the battery-side terminal,
• a relay member is provided for connecting between the battery-side connection part of the mobile electric device and the electric equipment-side connection part of the electric equipment,
• the battery-side connection part comprises:
• a lateral side wall part having an outer surface and an upper end;
• a battery-side slip-out prevention part that is provided on the outer surface of the lateral side wall part and is configured to be connectable to the relay member and forms a slip-out prevention structure at a connection portion between the battery-side connection part and the relay member;
• and
• a battery-side water-stop part that is provided on the outer surface of the lateral side wall part and is configured to form a water stop structure at the connection portion between the battery-side connection part and the relay member,
• the battery-side terminal is provided on the upper end of the lateral side wall part to allow the electric equipment-side terminal to be connected to the battery-side connection part from above, and
• the electric equipment-side connection part comprises:
• an electric equipment-side slip-out prevention part that is connectable to the relay member and is configured to form the slip-out prevention structure at a connection portion between the electric equipment-side connection part and the relay member;
• an electric equipment-side water-stop part for forming the water stop structure at the connection portion between the electric equipment-side connection part and the relay member, wherein
• the relay member is a cylindrical member separate from the mobile battery device and the electric equipment,
• the relay member has an inner side surface, an inner threaded part provided on the inner side surface, and an annular-shaped recess formed on the outer surface,
• the inner threaded part of the relay member engages with the battery-side slip-out prevention part,
• the annular-shaped recess of the relay member engages with the electric equipment-side slip-out prevention part of the electric equipment,
• a seal member as the battery-side water-stop part abuts with the inner side surface of the relay member and abuts with a seal member as the electric equipment-side water-stop part to thereby form inside the relay member a water stop structure between the relay member and the battery-side water-stop part, and a water stop structure between the relay member and the electric equipment-side water-stop part, and
• the electric equipment-side connection part is fitted into the relay member to form slip-out prevention by the battery-side slip-out prevention part and water stop by the battery-side water-stop part.
