A semiconductor device includes a semiconductor chip, a first terminal, a case, and a second terminal. The semiconductor chip includes the first electrode and the second electrode. The first terminal is electrically connected to the first electrode of the semiconductor chip. The case accommodates the semiconductor chip. A part of the first terminal is embedded in the case. The second terminal includes a conductive portion electrically connected to the second electrode of the semiconductor chip and a projection electrically insulated from the conductive portion. The first terminal includes a through hole provided in a portion exposed from the case. The projection is inserted into the through hole.

An input connector assembly, which is for detecting residual current and adapted for connecting power sources to electric equipment of electric vehicles, includes a wire terminal block, lock and release mechanisms, a residual current sensor, and a support holder. The wire terminal block has wire terminals for receiving electrical wires. The lock and release mechanisms are connected to the wire terminal block for fixing electrical wires to conductors in the wire terminals. The residual current sensor is adapted to be mounted to a flat surface. The support holder is designed to be placed above the residual current sensor and to be connected to the flat surface. The support holder is further adapted for supporting the wire terminal block in a position above the residual current sensor. Conducting connection pins run from the conductors in the wire terminals through openings in the residual current sensor to the flat surface.

The present disclosure relates to a three-phase terminal block having a leakage current limiting function, in which a leakage current may be limited by expanding an area of a neutral line of a three-phase four-wire line connected to the terminal block, and thus the risk of electric shock to the human body due to the leakage current may be minimized.

A terminal connector and an electric drive assembly are disclosed. A plurality of conductive members of the terminal block and the filter part are disposed in the housing, and a first connection end and the second connection end are respectively disposed at two ends of the extension body to conduct current. Thus, a plurality of first segments are disposed on the extension body, and the plurality of first segments are arranged at intervals to form an intermediate component disposed inside the magnetic ring. This allows the conductive member to pass through the magnetic ring multiple times via the intermediate component, thereby increasing the coupling strength between the terminal block and the magnetic ring and improving the filtering effect of the magnetic ring on common-mode noise. On the other hand, it avoids the need to set capacitors on the terminal connector. Thereby, the structure of the terminal connector is simplified, and its volume is made more compact.
