Electrical connector including a short-circuit terminal, and unit containing the same

A connector comprising:

• at least two terminal fittings;
• a connector housing having terminal-receiving chambers for receiving the terminal fittings;
• and
• a short-circuit terminal for electrically connecting the two terminal fittings to each other,
• wherein when the connector is connected to a mating connector, at least one of connections between the short-circuit terminal and the two terminal fittings is canceled,
• wherein the short-circuit terminal includes:
• a fixed part to be fixed to the connector housing;
• a resilient contact piece, one end of which is continued to the fixed part, and extended from the fixed part toward the mating connector, the other end of which is a free end and resiliently contacts one of the two terminal fittings;
• and
• a contact regulating part for preventing a deformation of the resilient contact piece so that the other end of the resilient contact piece is not projected toward the one of the terminal fittings.
