Abstract: An electrical connection box includes a lower cover, an upper cover, a connector front opening, bus bars, four first ribs formed of two pairs opposing each other with the bus bar, formed on the lower cover, interposed therebetween, and four second ribs formed of two pairs opposing each other with the bus bar, formed on the upper cover, interposed therebetween. The first ribs and the second ribs are provided such that a pair of ribs is provided to oppose each other on one side and on another side with the bus bar interposed therebetween in a vertical direction, and a pair of ribs is provided to oppose each other on one side and on another side with the bus bar interposed therebetween in a width direction. When viewed from a direction of assembling, the first ribs and the second ribs are provided at different positions.

Abstract: A protective cover structure includes a protective cover that is fitted to an assembly work opening disposed in a wall of a case in which electric components are accommodated, thereby closing the opening, and a fitting detecting connector that detects that the protective cover is fitted to the assembly work opening. The fitting detecting connector includes a receptacle connector which is fixed to an interior of the case and an insertion/extraction connector which is disposed on the protective cover in a mutually insertable/extractable manner while being opposed to the receptacle connector. The receptacle connector includes a tubular housing and fitting detecting conductors in the tubular housing. The insertion/extraction connector holds a pair of detecting electrodes which are electrically conductible with the fitting detecting conductors, and is molded integrally with the protective cover.

Abstract: An electrical component device includes an internal conductor, a case and a fitting detection connector. The internal conductor is connected to an electrical component and includes a fastening part configured to be fastened with an external conductor. The case accommodates the electrical component and the internal conductor and has a wall surface formed with a fastening opening for fastening the external conductor to the internal conductor. The fitting detection connector detects that a cover member closing the fastening opening is installed to the fastening opening and includes a receiving connector which is fixed inside the case and a detachable connector which is attached on the cover member. The wall surface extends in the gravity direction. The receiving connector has a receiving surface extending to a vicinity of an inner wall surface of the case and positioned below the fastening part in the gravity direction.

Abstract: A wire holder includes: a holder body attachable to a tubular body; wire passing holes formed in the holder body; and second locking parts provided on a periphery of the holder body and engageable with respective first locking parts of the tubular body. The holder body is divided along an axial direction of the wire passing holes into holder elements containing at least adjacent first and second holder elements, and is formed by superposing the holder elements. Each holder element includes at least one of the wire passing holes and at least one of the second locking parts. A first dividing surface of the first holder element is provided with a rib extending in the axial direction. A second dividing surface of the second holder element opposing the first dividing surface is provided with a groove with which the rib is engaged by sliding.

Abstract: A wire holder which is configured to hold an electric wire that is to be passed through a housing, includes: a resin-made holder body which is inserted into the housing, and in which a wire passing hole through which the electric wire is to be passed is formed; and annular rubber packings which are attached to an outer surface of the holder body and an inner surface of the wire passing hole, respectively, and which are formed by insert molding in which the holder body is set in a molding die.
