Plug detection electrical receptacle

摘要

A plug detection electrical receptacle includes a dielectric housing having at least one passage with an open mating end for receiving a male terminal of a complementary mating electrical plug and an opposite end communicating with a switch on a substrate. A female terminal is disposed in the passage for engagement by the male terminal. A detect switch is located in proximity to the passage for actuation by the male terminal when the male terminal is inserted into the passage in engagement with the female terminal. The detect switch includes an actuator at the opposite end of the passage, the actuator including a male terminal engaging portion and a switch engaging portion. A first flexible skirt extends from the actuator about the periphery thereof into sealing engagement with the substrate about the switch thereon. The flexible skirt supports the actuator with the switch engaging portion out of engagement with the switch on the substrate. The skirt flexes in response to engagement of the actuator by the male terminal to move the switch engaging portion into engagement with the switch. A second flexible skirt depends from the actuator and mounts the switch engaging portion thereon. The second flexible skirt flexes to allow for overtravel of the actuator after the switch engaging portion has engaged the switch on the substrate.
