ABSTRACT:
An electrical card connector for electrically coupling with an external plug, includes an insulative housing that receives a plurality of contacts and a pair of mixed latching means therein. Each mixed latching means consists of a spring bar with a protrusion extending integrally with the housing, and a metallic spring buffer disposed inside the housing. Each spring buffer includes a spring arm portion preloaded by the spring bar at a first supporting section thereof, a second supporting section formed at a free end of the spring arm portion and spaced apart from a stopper wall formed on the housing thereby constructing the spring arm portion as a cantilevered beam. After the spring bar is progressively deformed to reach a specific deformation due to the coupling between the plug and connector, the second supporting section of the spring arm portion can abut against the stopper wall to transform the spring arm portion as a simple support beam. Therefore, a maximum resilient force is exercised by the spring arm portion on the spring arm to have the protrusion suddenly snap with a notch formed on the plug so as to create a resounding audio effect to inspect the locking status between the mated connector and plug.
