| 20090120687 | Electrical connector with outer retainer ring and internal unidirectional conductor retainer - Various embodiments of an electrical connector assembly that includes a connector body having an inlet end portion and an outlet end portion. The outlet end portion is held in a knock out hole of an electric box and the inlet end portion is provided with an adjacent opening for receiving a wire conductor retainer in the form of a flat spring configured to be readily connected to an external portion of a connector body for ease of manufacture and assembly. An electric conductor can be unidirectionally inserted in the inlet end portion and secured thereto so as to prohibit any unintentional separation from the connector body, all without the need of any tools. | 05-14-2009 |
| 20100084188 | Method For Knock Out Feature In Brittle Material - The present invention relates generally to electrical insulation barriers. More particularly, the invention encompasses an electrical insulation barrier having knock-out features for an electronic apparatus. The electrical insulation barrier is preferably made from a brittle material, such as, for example, a thermoset insulating material, a glass reinforced polyester laminate material (such as, for example, GPO-1, GPO-2, GPO-3), and the like. The electrical insulation barrier is preferably used to insulate and/or isolate electrical conductors. With this invention a single master or universal type part can be made and used in many configurations and locations dependent on the design of the electronic apparatus. The invention allows for the creation of one or more opening in the electrical insulation barrier by knocking-out or removing one or more pre-defined shapes to allow clearance for intersecting electrical parts. With this invention one can consolidate many single use electrical insulation barriers into a few master parts that the user can customize to fit the application by removing the knock-outs as desired. The present invention also relates to electrical insulation barrier for switchgear, panel boards, and circuit breakers, along with electrical insulation barrier for low voltage switchgear and switchboard assemblies. | 04-08-2010 |
| 20100193241 | METHOD OF MAKING A REPLACEABLE KNOCKOUT PART IN A METAL PANEL AND SYSTEMS THEREOF - A product according to one embodiment includes a metal panel having a main portion and a knockout portion formed therein, the knockout portion being coupled to the main portion by at least one web of metal contiguous to both the knockout portion and the main portion, the at least one web allowing detachment of the knockout portion from the main portion, wherein the knockout portion includes at least one member insertable in one or more apertures in the main portion for allowing re-coupling the knockout portion to the main portion after detachment therefrom. | 08-05-2010 |
| 20100243315 | Removable Knockout Plate For Enclosures - The present invention relates generally to panels or enclosures. More particularly, the invention encompasses a removable knockout plate for enclosures. The present invention is also directed to a novel electrical panel or enclosure where at least a portion of at least one removable plate or panel is removably attached to a frame. The removable plate can be removed and can be cut at desired locations to create holes or openings for electrical components. The removable panel or plate can be a blank plate where at least one opening is created, as needed, or the removable panel can have at least one knockout which can be removed from the removable panel or plate, as needed. | 09-30-2010 |
| 20100307817 | Method for retrofitting air plenum grommets - A new and improved method is provided for repairing or retrofitting cable management apparatus used in raised flooring systems constructed to deliver a source of building air, or HVAC, while managing cables passing through an access port constructed in the raised flooring structure without jeopardizing the underfloor plenum air delivery systems. A raised floor grommet assembly provides a grommet locking mechanism defining an assembly retention system that lockingly engages and removeably disengages a first section and a second section of the grommet assembly, and an access port locking mechanism that lockingly engages and removeably disengages an access port constructed in the raised flooring structure. The unique grommet assembly provides an efficient and effective method and apparatus designed for retrofitting cable management systems and accommodates system upgrades, workstation relocation, and HVAC management. | 12-09-2010 |

| 20120222897 | REPLACEABLE KNOCKOUT PART IN A METAL PANEL AND SYSTEMS AND METHODS THEREOF - In one general embodiment, a product includes a metal panel having a main portion and a knockout portion formed therein and detachably coupled thereto, wherein the knockout portion includes at least one member insertable in one or more apertures in the main portion for allowing re-coupling the knockout portion to the main portion after detachment therefrom. In another general embodiment, a product includes a metal panel having a main portion and a knockout portion formed therein and detachably coupled thereto, wherein the main portion includes at least one member insertable in one or more apertures in the knockout portion for allowing re-coupling the knockout portion to the main portion after detachment therefrom. | 09-06-2012 |
| 20130175086 | KNOCKOUT FOR ELECTRICAL BOX - A knockout structure for a wall of an electrical box includes a cutout that penetrates through the thickness of the wall to form a knockout on an interior of the cutout along a substantial perimeter of the knockout. The knockout structure also includes a first bridge section interrupting continuity of the cutout and maintaining a connection between the wall and the knockout. The knockout structure further includes a second bridge section interrupting continuity of the cutout and maintaining a connection between the wall and the knockout, the second bridge section being different than the first bridge section and on a same half of the perimeter of the knockout. | 07-11-2013 |
