  • Publication number: 20180241155
    Abstract: A movable connector with which an insertion force of a connection object that places a load on a solder portion can be reduced, that has a floating function, and that can be reduced in size is provided. As a result of a pushing operation in which an operation housing is pushed into a fixed housing, a relay terminal is conductively connected to a substrate connection terminal, which is in conductive contact with a substrate, and a pin terminal, which is disposed in a movable housing and serves as the connection object, in the movable housing. Accordingly, the overall size of the movable connector can be reduced. In addition, the insertion force applied to the pin terminal is not applied to the solder portion by which the movable connector is fixed to the substrate, so that conduction failure does not occur.

  • Patent number: 10039137
    Abstract: An electric power tool includes a wireless transmission unit and a transmission control unit that causes the wireless transmission unit to transmit a linking signal to a dust collector to thereby cause the dust collector to operate in a linked manner. An operation mode of the transmission control unit is shifted from a normal mode to a pairing mode by operation of an operation unit. When in the pairing mode, the transmission control unit causes the wireless transmission unit to transmit a pairing request signal to the dust collector. In this way, the electric power tool can be registered in the dust collector as a link target appliance.
