An electrical connector assembly includes a generally planar metallic substrate having a surface with an electrically nonconductive coating and an electrical connector having a contact tab extending therefrom that is in mechanical and electrical contact with the metallic substrate. The contact tab defines two sharp points that are formed by two triangular portions of the contact tab that pierce the electrically nonconductive coating. An electrical shield incorporating the contact tab and a method of forming the electrical shield are also provided herein.

A housing assembly for a plier-operated insulation-displacement connector includes a first housing section and a second housing section. The first housing section and the second housing section are movable with respect to one another. Each of the first housing section and the second housing section has a top surface grippable by a jaw of a plier. The top surface of the first housing section has a concave area in a first direction. The top surface of the second housing section at least one of: has a concave area in the first direction, and is slidably arranged along the first direction with respect to the top surface of the first housing section.

An electrical connector includes a clamp body having a substantially C-shaped configuration defining an interior cavity. A wedge is configured to be inserted into the clamp body. The wedge has a wedge body defining a conductor channel and a plurality of fins extending from the wedge body into the conductor channel. The plurality of fins is oriented to pierce an insulation layer of a conductor when the wedge is inserted into a clamp body.

A module mounting system may include a photovoltaic (PV) module frame including a mounting rail. The module mounting system may include a spring clip with a PV module frame interfacing element and a clip interfacing element. The spring clip may apply spring force via deformation to lock the PV module frame and a clip together. A second embodiment of the spring clip may include an upper component having one or more arms and a lower component having a central loop configured to rotate relative to each other and interface with the PV module frame or the mounting rail. A second embodiment of the module mounting system may include screwless clips including outer walls and inner walls coupled together as a continuous sheet of material. The screwless clips may couple to a respective mounting flange and a respective frame flange to lock the mounting purlin and the PV module frame together.

A lighting apparatus includes a wire connector, a driver and a light source. The wire connector is used for connecting an external wire and an internal wire. The external wire includes a first external sub-wire and a second external sub-wire. The internal wire includes a first internal sub-wire and a second sub-wire. The wire connector has a scraper for cutting contact parts of the internal wire and the external wire for the first external sub-wire to be electrically connected to the first internal sub-wire and the second external sub-wire to be electrically connected to the second internal sub-wire. The driver is used for connecting to an external power via the internal wire and the external wire and for converting the external power to a driving current. The light source receives the driving current to emit a light.
