Bonding clamps used to assembly photovoltaic (PV) arrays and provide an electrical bond between PV module frames forming part of the PV arrays is provided. The bonding clamp includes an electrically conductive body, at least one electrical bonding member extending from the body, and at least one pressure member extending from the body. The bonding clamp may also include one or more spacers to provide a uniform spacing between PV module frames.

Various implementations of grounding clamps and torque-controlled fasteners are disclosed. The grounding clamps may be used to attach grounding conductors to various structures, such as pipes, conduit, grounding rods etc. The torque-controlled fasteners may use various techniques to control the amount of torque applied to the fasteners used with the grounding clamps described herein.

A snap-in terminal connector for a conductor includes a housing having a first opening for receiving the conductor and a second opening arranged at an angle, and preferably perpendicular, relative to the first opening for an actuator for the connector. The connector includes a bus bar, a clamping spring, and a rotatable lever operable by the actuator. The clamping spring is mounted on the housing and includes integral clamping and support legs. The clamping leg is operable between latching and clamping conditions. The actuator is operable to rotate the lever which tensions the clamping spring by pressing the clamping leg toward the support leg. A retaining assembly on the support leg retains the clamping leg in the latching position. When a conductor is inserted into the housing first opening, the leading end of the conductor presses against the clamping spring support leg to release the clamping leg which presses the conductor against the bus bar and retains the conductor within the housing.

The present invention relates to a ground terminal for an electronic device. The ground terminal comprises a ground cable connecting device, an electrical switch, an electrical conductor connecting the ground cable connecting device to the electrical switch. The ground terminal and its ground cable connecting device is configured so that the electrical switch is brought in to a first mode in response to an electrical wire being connected to the ground cable connecting device, the first mode being a mode in which the switch establish electrical conduction between an electrical circuit of the electronic device and the ground cable connecting device. Moreover, the ground terminal and its ground cable connecting device is configured so that the electrical switch is in a second mode when no electrical wire is connected to the ground cable connecting device, the second mode being a mode in which the switch is electrically isolating the electrical circuit of the electronic device and the ground cable connecting device from each other.
