  • Jack security device
    Patent number: 4911646
    Abstract: A jack security device, especially suitable for standard telephone jacks mounted at a panel of an access cabinet, can either prevent unauthorized access to a secured empty jack or prevent removal of a plug from a jack in use. An end portion of the device partially covers the plug receiving jack opening. The main body of the device carries a key-actuated tumbler and slides into an access cabinet housing recess adjacent to the jack. A locking tab carried by an inner end of the tumbler engages a surface provided in the housing to place the device in a locked condition with the flanged end portion partially covering the secure jack. Additionally, arrangements within the access cabinet are provided for overriding a locked condition of the device without the need for a lock actuating key.
