Abstract:
An audio jack comprising:an insulating housing defining a longitudinal plug-insertion hole therethrough for receiving a mating plug; at least one resilient contact received in the housing and including a fixing section for retaining the resilient contact in the housing and a cantilevered beam diagonally extending opposite to the fixing section, the beam extending into the hole from a top wall of the housing and forming a contact section at a distal end thereof for contacting the plug; and a retention pad including a base retained in the housing and a protrusion formed on the base for pressing against the plug; wherein a groove is defined in an inner sidewall of the housing for receiving the retention pad; wherein the base of the retention pad forms a pair of barbs on two opposite edges thereof, and wherein the groove comprises a pair of cutouts for latching with the barbs; wherein the protrusion of the retention pad is formed to a predetermined height; wherein at least one fixed contact is provided to cooperate with the at least one resilient contact, the at least one fixed contact including a base and a solder tab perpendicularly extending from the base for surface mounting on a circuit board, and wherein at least one groove is defined in an outer sidewall of the housing for receiving a corresponding base; wherein the at least one resilient contact comprises a horizontal linking section extending perpendicularly from the fixing section, and a flexible section extending diagonally from the linking section and pointing away from the fixing section; wherein the cantilevered beam inclinedly extends from the flexible section.
