Power Control Device
US Patent:
6461176, Oct 8, 2002
Filed:
Feb 22, 2000
Appl. No.:
09/507803
Inventors:
Norman C. Haas - Overland Park KS 66210
International Classification:
H01R 1344
US Classification:
439133, 200 33
Abstract:
A power control device has a first contact, a second contact, and a third contact aligned within slots of a housing. A cam having arms is aligned with a cylinder of a key lock assembly. The key lock assembly and cam are mounted in the housing. An electrical connector having electrical leads is mounted in an aperture within the housing so that the leads of the electrical connector are connected to the first contact and the third contact. The cylinder of the key lock assembly may be rotated, thereby rotating the cam. The arms of the cam cause locking pins on the first and second contacts to engage apertures of an electrical device plug plugged into the receptacle of the housing. Simultaneously, a lug on the cam operates on the third contact to force the third contact out of electrical connection with the second contact, thereby eliminating the current flow to the electrical device plug.
Power Control Device
US Patent:
7582990, Sep 1, 2009
Filed:
Mar 2, 2006
Appl. No.:
11/366083
Inventors:
Norman C. Haas - Overland Park KS, US
International Classification:
H02J 1/00
US Classification:
307119, 439133, 439346
Abstract:
A power control device prevents unauthorized and unwanted use of electrical devices by locking the plug of the electrical device in the power control device, when the current flowing through the power control device is stopped. The device includes a switch, moveable between on and off conditions by moving a slide lock or bolt, typically by rotating a key in a locking structure. When the slide lock has moved into contact with the switch, such that it is in an off-condition and current is not flowing through the power control device, the slide lock has also locked the plug in the power control device. The electrical device is temporarily inoperable and can not resume normal operation until the power control device is unlocked.
