In various representative aspects, an apparatus for clamping and grounding solar panel frames to a mounting rail is disclosed herein. The apparatus includes a fastener with an enlarged end, and a shank, with the enlarged end having one or more sharp protrusions that resemble teeth, and a washer with one or more sharp protrusions, and an opening. When installed, the shank is inserted through the opening of the washer, the sharp protrusions of the enlarged end penetrate either the lower or upper surface of the mounting rail and the sharp protrusions of the washer penetrate the other surface of the solar panel frames while at the same time creating a grounding path through the apparatus.

A terminal block is provided with a conductive member including a relay portion extending in an extending direction from a device side and a connecting portion extending in a direction perpendicular to the extending direction and to be electrically connected to a mating conductive member, and a housing for integrally holding the conductive member. The housing includes a resin portion for molding the relay portion and a peripheral wall surrounding the resin portion. A sealing member is externally fit on the resin portion and the peripheral wall covers the sealing member from outside of the resin portion. A mating housing integrated with the mating conductive member is fit to the resin portion.

In an electrified transmission, motor leads are electrically connected to inverter leads by being squeezed between a compressible limiter on a terminal base and a prong of a cover plate. Several such connection are accomplished by installation of the cover to an inverter housing. This method reduces the number of assembly steps and is more robust to variations in the positions of the leads. The terminal base may be part of an inverter module within the inverter housing.

A connector includes: a number of busbars; a housing holding of the busbars; and a cover mounted on the housing. The busbars each have a fastening target portion to connect a terminal metal fitting by using a bolt. The fastening target portion is housed in a housing room, and a number of the housing rooms is defined between the housing and the cover. One of the housing rooms corresponding to the fastening target portion of one of the busbars and another of the housing rooms corresponding to the fastening target portion of another of the busbars are separated with a partition wall, and at least part of the partition wall has a liquid-tight portion formed by engaging a projection of one of the housing and the cover with a recess of the other of the housing and the cover.
