A discharge device for a rolling bearing as well as a method for discharging electrostatic loads to a rolling bearing including a flexurally elastic conductor. The conductor includes a first conductor section and a second conductor section for forming a contact arrangement at a rolling bearing. The first conductor section electrically engages a first bearing ring and the second conductor section electrically engages a second bearing ring of the rolling bearing to form an electrically conductive connection between the first bearing ring and the second bearing ring.

A plug-in connector comprises a first connecting part with at least one first contact element and a second connecting part with at least one second contact element. The first connecting part is configured for being connected with and disconnected from the second connecting part. The first connecting part comprises a latching element with a snap-in member, and the second connecting part comprises a retaining sleeve configured for accepting the latching element. The latching pin and the retaining sleeve constitute a mechanical mechanism provided in addition to the at least one first contact element and the at least one second contact element. A mechanical interaction between the latching pin and the retaining sleeve enforces a predetermined motion pattern of the at least one first contact element relative to the at least one second contact element during a process of connecting or disconnecting the first connecting part and the second connecting part.

To neutralize static electricity in a charged coaxial cable with a decreased installation space. The first base member 2A and the second base member 2B are installed at the adapter 13 in order to interpose a box nut 13a of the adapter 13 therebetween and are fixed by fixing means 6. A flexible rod-like static electricity neutralizing contact 4 is erected on the second base member 2B parallel to the adapter 13. The static electricity neutralizing contact 4 is brought into contact with a central conductor and an outer conductor of a coaxial connector 15a before the coaxial connector 15a of a coaxial cable 15 is connected to the adapter 13, and static electricity in the charged coaxial cable 15 is neutralized.

A connector for electric vehicle supply equipment includes: a housing; a first electrical coupling member supported by the housing and that mates with an inlet of an electric vehicle, the first electrical coupling member including a first pin part; a second electrical coupling member supported by the housing and that mates with the inlet, the second electrical coupling member including a second pin part; and a conductive barrier supported by the housing that extends between the first and second pin parts. The conductive barrier interacts with at least one of the first and second pin parts to provide a conduction path for electrical power monitorable to evaluate electrical isolation of the first and second electrical coupling members and avoid electrical arcing or short-circuiting.

An electrical connector includes multiple terminals fixed to an insulating body. Each terminal has a contact portion electrically connected with a mating connector, and a conducting portion located behind the contact portion. The conducting portion extends out of the insulating body and is electrically connected with a circuit board. A grounding shell wraps outside the insulating body. A shielding shell rotates relative to the insulating body between a closed position and an open position. A first end of the shielding shell is electrically connected with the grounding shell. When the shielding shell is at the closed position, a second end of the shielding shell is electrically connected with at least one grounding medium electrically connected with the circuit board. When the shielding shell is at the open position, an observation window is formed between the shielding shell and the grounding medium to expose the conducting portions of the terminals.

This invention is an active cable or cables with a female micro USB or other connector recessed at the rear end of the HDMI plug for connecting external power when needed. The recessed connector is connected to an internal circuitry that combines this external power with the power from the source or sink device via a straight or “OR” circuits. This design is clean when no external power is needed because there're no dangling pigtails with USB plugs. When external power is needed because the source or sink devices can't provide enough current, the user can use for example widely available male micro USB to male USB cable (the standard charging cable for most Android phones and many other computer or phone accessories) or other cable to get external power, and the cable length can be selected to fit the application.
