Electrical connection box

摘要

An electrical connection box comprises lower and upper casings capable of being combined with each other, an electrically insulating wiring board located between the casings and having a wire laid in a desired shape thereon, a busbar in contact with at least a part of a wire laying surface of the wiring board, and an insulating plate located between the lower casing and the wiring board and/or between the upper casing and the wiring board. The insulating plate has thereon a projection for pressing the laid wire away from the busbar. The wiring board is formed with a laying groove in which the wire is laid. Post-formed protuberances for preventing the wire from getting out of the laying groove are formed in predetermined portions of the laying groove.
