Incomplete fitting prevention connector
View Patent ↗An incomplete fitting prevention connector includes a first connector, a second connector that is fitted to the first connector, and a connector position assurance lock that is slidably mounted to an outer side of the second connector. The first connector includes a male beak, a short spring and a terminal. The second connector includes a female lock passing over the male beak and a short-circuit removal plate part inserted between the short spring and the terminal. A draw-in slanted surface is formed at a leading end of the male beak, a restoring force for returning the female lock to its original position serves as a driving force for fitting the connector when the female lock reaches the draw-in slanted surface, and the insertion force of the short-circuit removal plate part applied between the short spring and the terminal is reduced.
1. An incomplete fitting prevention connector comprising:
a first connector;
a second connector that is fitted to the first connector; and
a connector position assurance lock (CPA) that is slidably mounted to an outer side of the second connector,
wherein the first connector includes a male beak, a short spring and a terminal,
the second connector includes a female lock which passes over the male beak and a short-circuit removal plate part inserted between the short spring and the terminal, and
a draw-in slanted surface is formed at a leading end of the male beak,
a restoring force for returning the females lock to its original position serves as a driving force for fitting the connector when the female lock reaches the draw-in slanted surface, and the insertion force of the short-circuit removal plate part applied between the short spring and the terminal is reduced.
2. The incomplete fitting prevention connector according to claim 1 , wherein the CPA includes a CPA lock passing over the male beak and the female lock and,
a leading-end slanted surface is formed at a leading end of the female lock and one-action property is secured by using a restoring force for returning the CPA lock to its original position as the driving force when the CPA lock reaches the leading-end slanted surface.
3. The incomplete fitting prevention connector according to claim 1 , wherein a vertical surface of the male beak abuts a vertical surface of the female lock while the connector is fit.
4. An incomplete fitting prevention connector comprising:
a first connector;
a second connector that is fitted to the first connector by moving the first connector in a fitting direction with respect to the second connector; and
a connector position assurance lock (CPA) that is slidably mounted to an outer side of the second connector,
wherein the first connector includes a male beak, a short spring and a terminal,
the second connector includes a female lock which passes over the male beak and a short-circuit removal plate part inserted between the short spring and the terminal, and
a draw-in slanted surface is on a back side of the male beak, opposite the fitting direction,
wherein a restoring force for returning the females lock to its original position serves as a driving force for fitting the first connector with the second connector when the female lock contacts the draw-in slanted surface, such that an insertion force for inserting the short-circuit removal plate part between the short spring and the terminal is reduced,
wherein the CPA includes a CPA lock passing over the male beak and the female lock and, a leading-end slanted surface is formed at a leading end of the female lock and one-action property is secured by using a restoring force for returning the CPA lock to its original position as the driving force when the CPA lock reaches the leading-end slanted surface.
