  • Patent number: 10283308
    Abstract: A busbar includes a plurality of main terminals (upstream side terminal, downstream side terminals) and one auxiliary terminal conductively connected to one of the main terminals and is press-formed in an integrated manner. The auxiliary terminal is connected to the main terminals through connection bars which are all cut off, except for one, in a cutting process after a pressing process, and the circuit configuration can be changed by selectively cutting off the connection bars. Therefore, there is no need to change the shape of a press die, and the production efficiency can be improved using a die having a uniform shape.

  • Patent number: 10250002
    Abstract: An electric connection block is provided with a bus bar formed from a press-formed product of a metal plate member and a resin-made housing insert molded integrally with the bus bar. The bus bar is provided with a flat plate-shaped main plate part and a standing terminal erected by bending a base end connected to a portion of the main plate part relative to the main plate part. The electric connection block is manufactured by insert molding the housing integrally with the bus bar in a before-bending state where the standing terminal is located on the same plane as the main plate part, and bending the base end of the standing terminal to thereby erect the standing terminal relative to the main plate part after the insert molding of the housing.

  • Patent number: 10141148
    Abstract: A connection portion of a locking member is bent such that the connection portion is made apart from a second upper surface portion as the connection portion is made apart from a first arm portion, and is bent such that the connection portion is made apart from a side surface portion as the connection portion is made apart from a second arm portion. Even when a tolerance is generated in a direction substantially orthogonal to the side surface portion at the time of installing a base body in an installation surface portion of a battery, it is possible to absorb the tolerance by deforming the connection portion, and to lock a locked portion in a lower end edge.

  • Patent number: 10071444
    Abstract: A laser cladding apparatus includes a powder supplier to supply metal powder to a portion to be processed, a laser to irradiate the portion to be processed with laser so as to melt the metal powder for cladding, and a controller. The powder supplier includes a gas pressure gauge, and the controller stores, as an initial value, a gas pressure value measured by the gas pressure gauge when the metal powder supplied by the gas pressure reaches the portion to be cladding-processed. In operation after storing the initial value, the controller sets, as a reference time, timing when the gas pressure gauge measures a same pressure as the initial value, and outputs a start signal for laser irradiation to the laser based on the reference time.
