Abstract:
A jack assembly which includes a contact switching system for receiving a coaxial plug, comprising:an insulative housing having a plug-receiving chamber with an opening for receiving the coaxial plug in a plug-insertion direction; a fixed terminal mounted on the housing and having a fixed switch contact portion located outside said plug-receiving chamber; and a movable terminal mounted in the housing and including a spring arm at least partially located inside the plug-receiving chamber in the path of insertion of the coaxial plug and a movable switch contact portion connected to the spring arm and extended outwardly from the housing for movement therewith into and out of engagement with the fixed switch contact portion of the fixed terminal, the movable switch contact portion being located outside the plug-receiving chamber, whereby engagement of the coaxial plug with the spring arm inside the plug-receiving chamber is effective to cause the movable switch contact portion of the movable terminal to move relative to the fixed switch contact portion of the fixed terminal outside the plug-receiving chamber, wherein the movable switch contact portion of the movable terminal and the fixed switch contact portion of the fixed terminal comprise generally planar plates having interengaging wiping surfaces of substantial size which wipe over each other when the contact portions move relative to each other.
