Electrical connector including a short-circuit terminal, and unit containing the same
View Patent ↗A connector unit includes a mating connector and a connector. The mating connector includes a canceling piece for canceling connections between the female terminals of a short-circuit terminal when the mating connector is connected to the connector. The connector includes a connector housing, female terminals, a short-circuit terminal, and a contact regulating part. The contact regulating part includes a regulating piece and a regulating projection. A through hole for passing a resilient contact piece of the short-circuit terminal is provided on the regulating piece. The regulating projection is projected from the other end of the resilient contact piece. The regulating projection prevents the other end from projecting toward the female terminal through the through hole.
1. 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.
2. The connector as claimed in claim 1 ,
wherein the contact regulating part is formed in between the short-circuit terminal and the one terminal fitting, and includes a regulating piece having a through hole for allowing the center of the resilient contact piece to touch the one of the terminal fittings, and a regulating part for preventing the other end of the resilient contact piece from passing through the through hole and projecting from the regulating piece toward the one of the terminal fittings.
3. The connector as claimed in claim 2 ,
wherein the regulating part is formed on the other end of the resilient contact piece, and includes regulating projections projected from the other end in a width direction of the resilient contact piece.
4. The connector as claimed in claim 2 , further including a spacer attachable to and detachable from the connector housing, said spacer preventing the terminal fittings from falling out of the terminal-receiving chambers, and including the regulating piece.
5. The connector as claimed in claim 1 ,
wherein the short-circuit terminal further includes a contact piece for contacting the other terminal fitting.
6. The connector as claimed in claim 1 ,
wherein the short-circuit terminal is interposed between the two terminal fittings.
7. A connector unit comprising: a connector as claimed in any one of precedent claims; and a mating connector connected to the connector, and including a canceling part for canceling at least one of connections between the sort-circuit terminal and the two terminal fittings when the mating connector is connected to the connector.
