Abstract
A freely rotating connector security shield for use with BNC or other connectors to prevent unauthorized access to the connector. The connectors appropriate for use with the security shield are secured by rotation about the connector axis to mate with the corresponding connector. According to the present invention, such axial connector rotation is prevented by surrounding the connector with a normally freely rotating cylindrical shield. Removal or insertion of the shielded connector from the mating connector requires the use of a corresponding installation tool. The connector is engaged through apertures in the shield which permit radial compressive forces by the installation tool to be applied across the connector. The connector thus held captive can now be connected to and removed from the corresponding mating connector.
Claims9
A security device for use with a connector having at least one recess requiring rotation for connection and disconnection, comprising:
- a security shield having a shape to substantially surround said connector and adapted to receive said connector therein, said shield having at least one radially disposed aperture therein;
- and
- shield locking means to prevent removal of said shield from said connector after installation, including a spring biased toward said recess when said connector is received by said shield to provide retention thereof;
- wherein said aperture is disposed to permit actuation of said connector.
Apparatus comprising:
- a connector;
- a security shield substantially surrounding said connector having an aperture;
- and
- means for gripping the connector through an aperture including:
- a lever means having two elements movable in opposition, a first element having a protrusion disposed inwardly, said protrusion being adapted to be received by at least one of said apertures, and adapted to apply a force upon said connector through said aperture;
- a second element for providing a force in opposition to said first element;
- and
- means for applying a force in radial opposition to said protrusion;
- wherein said protrusion and said means for providing a force in radial opposition act in concert to allow a rotational torque to be applied to the connector.
