A novel cable connector comprises a main body, a clamp, a conductor assembly, and a controller. The main body is provided with an installation cavity and a receiving slot, and both sides of the receiving slot extend longitudinally to form a left and right wing. The clamp is arranged in the receiving slot, the receiving slot forming a passage for accommodating a cable. The conductor assembly is arranged on the installation cavity of the main body, and comprises a sharp lower end, which protrudes from the top surface of the receiving slot and is located in the passage. The clamp is located between the controller and the main body, the controller cooperates with the left wing and the right wing under an external force to directly apply a force to the clamp to drive the clamp to move towards the top surface of the receiving slot.

A bail for forming a mechanical and electrical connection includes an inboard section and an outboard section. The inboard section includes an elongate, electrically conductive multi-strand conductor. The outboard section includes an elongate, electrically conductive solid rod conductor electrically connected to the multi-strand conductor.

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.

An assembly configured to receive twisted pairs of conductors terminated by a miniplug and a pair of conductor contacts. The assembly comprises a housing comprising a first surface comprising a socket disposed therein; wherein the socket is configured to accept a plurality of miniplugs, illustratively in a 2×2 configuration, wherein pairs of socket contacts are exposed along at least one side wall of the socket and wherein the socket contacts are configured to be aligned with the conductor contacts such that each of the conductor contacts is in contact with a respective one of the socket contacts. A caddy is also provided which allows the miniplugs to be arranged in a 2×2 arrangement for subsequent insertion into a socket or the like.

Various implementations of insulation piercing connectors are disclosed. The insulation piercing connectors include a simple and efficient design for providing electrical tap connections to a power cable for voltage detection purposes. The insulation piercing connector includes at least a top housing and a bottom housing that come together to receive the power cable. Terminal contacts are housed internally within the insulation piercing connector, and the terminal contacts are positioned to pierce the power cable when the insulation piercing connector is assembled into an operational state.

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.

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.
