Abstract

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.

Claims (9)

1 . An input connector assembly for detecting residual current and adapted for connecting power sources to electric equipment of electric vehicles,

the input connector assembly comprising:

a wire terminal block with wire terminals for receiving electrical wires;

lock and release mechanisms connected to the wire terminal block for fixing electrical wires to conductors in the wire terminals;

a residual current sensor adapted to be mounted to a flat surface;

a support holder having a hollow design enabling the support holder to be positioned above the residual current sensor and to be connected to the flat surface,

wherein a top of the support holder is adapted for supporting the wire terminal block in a position entirely above the residual current sensor, and wherein conducting connection pins run from each conductor in the wire terminals through openings in the residual current sensor to the flat surface.

2 . The input connector assembly according to claim 1 , further comprising a distribution circuit board adapted for distribution of connectors running from the wire terminals to respective openings in the current sensor.

3 . The input connector according to claim 1 , wherein the flat surface is a printed circuit board.
