Assembly for clamping and grounding objects
In various representative aspects, an apparatus for clamping and grounding solar panel frames to a mounting rail is disclosed herein. The apparatus comprises 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.
1. An assembly for affixing a first object to a second object and a third object and providing a grounding path between the objects comprising:
a. first and second frames each comprising an elongated channel for receiving a solar panel;
b. a rail guide;
c. an electrically conductive fastener comprising:
i. a shank extending from an enlarged end such that the shank terminates at an opposite end and the enlarged end further comprises a top and a bottom surface wherein the top surface comprises at least one raised portion for penetrating a surface of the rail guide; and
ii. a female member comprising a nut end and a sheath extending from the nut end, the sheath being configured to receive the shank;
d. an electrically conductive piercing member comprising:
i. a base with a central opening configured to receive the sheath of the female member therethrough;
ii. a pair of opposing ears with each respective ear being on an edge of the base of the piercing member such that the pair of ears extend downward in the direction of the enlarged end and act as spacers between the first and second frames; and
iii. at least one raised portion adjacent each ear disposed on the edge of the piercing member for penetrating a surface of the first and second frames respectively.
2. The assembly of claim 1 , wherein the sheath further comprises an internal thread and the shank further comprises an external thread for engaging the internal threads of the sheath.
3. The assembly of claim 1 , wherein the fastener and piercing member are metallic.
4. The assembly of claim 1 , wherein the nut end of the female member further comprises a nut for securing the piercing member to the first and second frames respectively.
