FIELD OF INVENTION

The field of this invention and associated embodiments relates to insulated covers, namely covers used to shield one from electricity. In particular, the present field relates to an electrically insulating cover for use in meter pans that assist in supplying electricity to structures including homes and businesses.

BACKGROUND OF INVENTION

An electric meter is a device that measures the consumption of electricity used by a residence, business or other location or electrically powered device. Tampering with such meters, especially on homes and businesses, can cause the meter to under-report consumed electricity thereby enabling an individual to use electricity without paying it. To combat this potential theft, meters will have a tamper proof tag and methods of opening the meter. Thus, a lineman, meter reader or electrician is generally required in order to perform any service or maintenance on the meter or customer owned meter socket equipment.
In order to perform work on the voltage innards of the electric meter, the lineman, meter reader, or electrician often must cut the taps leading into the meter or have the utility company perform a disconnect/reconnect of the flow of electricity before and after their work on the meter or meter socket if they are needed. This disconnect/reconnect is sometimes charged to the consumer as a fee by the utility company. If such a service is not performed, there is a risk of great bodily harm or death befalling the lineman, meter reader, or electrician. Thus, there is a need for a device that absolves the need for outside support (i.e. a utility company) and enables a licensed worker to perform their duties without having to cut the taps leading into an electric meter socket.
U.S. Pat. No. 3,644,878 describes a connector having a terminal with an outer insulating cover and an inner conducting portion and a conductor having an outer insulating cover and a conductor lug detachably connected to the inner conducting portion of the terminal. A resilient waterproof sheath extends between and is in sealing engagement with the insulating covers of both the terminal and the conductor. Each sheath end includes internal, annular ribs having a smaller diameter that the diameter of the engaged insulating cover material, thus deforming the insulating material into indentations. The resulting pressure from the sheath combined with the heat environment within the sheath provides a bonded seal between the sheath and the insulation material. The terminal outer insulating cover is formed into a retaining boss which is engageable by one of the internal, annular ribs at the terminal end of the sheath.
Various devices are known in the art. However, their stricture and means of operation are substantially different from the present disclosure. The other inventions fail to solve all the problems taught by the present disclosure.
The present invention provides for an insulative cover that can be used in an electric meter pan amongst other settings. The cover provides a safe and efficient tool for assisting a lineman, meter reader, or electrician in performing their duties, when working on load side of socket. At last one embodiment of this invention is presented in the drawings below and will be described in more detail herein.

SUMMARY OF THE INVENTION

The present invention describes an electrically insulative cover having a top panel; and at least one side panel having a length, wherein the at least one side panel is coupled to the top panel, wherein the top panel and the at least one side panel comprises a polymeric material. Preferably, there are four side panels, although the number of side panels may vary from about 1 to about 10 side panels. At least one of the side panels may have a length that is less than that of the other side panels. The electrically insulative cover is preferably formed from an electrically insulative rubber. In some instances, the cover has an adhesive disposed on the at least one side panel.
In another aspect of the present invention there is a system for shielding electricity having an electrically insulative cover comprising a top panel, four side panels, each having an outer surface, an inner surface, and a bottom surface, wherein at least one of the four side panels has a length that is less than that of the other side panels, an adhesive disposed on the bottom side of the four side panels, wherein the adhesive is removable; wherein the cover comprises a rubber based composition; and a meter pan having at least one lug, wherein the electrically insulative cover is placed over the at least one lug.
The electrically insulative cover may be positioned over the lug with or without electricity being supplied thereto. In order to fit over the lug, there may be at least one side panel having an angled bottom surface.
This accommodates any structure that may otherwise impede complete coverage of the lug. Preferably, the cover is formed from a silicone-based rubber although most any rubber should suffice, and a number of electrically insulative materials may be used.
Generally, the electrically insulative cover is shaped and designed to fit over one or more lugs in an electric meter socket. The shape of the lug may result in some variation of the shape of the electrically insulative cover. The cover is placed over a hot lug to protect the technician working on the apparatus. The cover may further have a removable adhesive to help ensure the cover stays in place while the technician is working. This prevents the cover from shifting out of place and placing the technician at risk for serious injury. The cover can comprise any material that is electrically insulative and other materials not known for their insulative properties but for other qualities (i.e. flexibility, strength, etc.) that may be combined with the electrically insulative materials.
In general, the present invention succeeds in conferring the following, and others not mentioned, benefits and objectives.
It is an object of the present invention to provide an electrically insulative cover that provides protection from electricity to individuals working with electrical equipment.
It is an object of the present invention to provide an electrically insulative cover that is used in an electric meter.

DETAILED DESCRIPTION OF THE INVENTION

The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals. Reference will now be made in detail to each embodiment of the present invention.
Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.
Referring now to FIG. 1, there is a meter pan 200 with the cover (not shown) having been removed. The meter pan 200 has electrical apparatus that directs the flow of electricity from a transformer to a structure such as a home or business. The line lugs 230 bring in the flow of electricity from an outside source, typically a transformer. The load lugs 235 bring the flow of electricity to the customer. A neutral 240 is used as a ground and does not typically carry the flow of electricity. The wiring 220 stems from the outside source of electricity to the line lugs 230 and from the load lugs 235 to the structure. The wiring 220 enters and exits the meter pan 200 through apertures 215. Screw plates 205 provide a secure connection between the line lugs 230 and the load lugs 235. These structures are connected to the back 210 or the meter pan 200 via an insulated block.
In FIG. 2 there is one embodiment of the present invention. The electrically insulative cover 100 is used in tandem to cover the line lugs 230 (see FIG. 1).
In FIG. 3 there is another embodiment of the present invention. The electrically insulative cover 100 here covers both line lugs 230 at the same time. The set-up is the same as shown in FIG. 2 with the difference being the area of coverage of the electrically insulative cover 100 with cutout for lines 220 and ground wire.
FIG. 4 shows the electrically insulative cover 100 from side view. Here, the features of the electrically insulative cover 100 are readily visible. The cover 100 has a top panel 105 and four (4) side panels 110. Two of the side panels 110 of insulative cover 100 may have a cutout 140 that will allow for a tight fit to accommodate lines 220.
Referring now FIG. 5, there is a second side view of the electrically insulative cover 100. The side panels 110 are coupled to the top panels 105. The top panel 105 and the side panels 110 may be integrated and formed of a single piece. The cutout 140 is visible, placement of it may vary.
In FIG. 6, the electrically insulative cover 100 is shown from a bottom view. The configuration of the side panels 110 is shown along with adhesive 115 disposed on bottom surface 130. Each of the side panels 110 are coupled to another side panel 110 and the top panel 105. Each of the side panels 110 has an outer surface 120, an inner surface 125, and a bottom surface 130. This leaves an opening 150 on the bottom side of the cover 100 which receives the line lug 230 (see FIG. 1). At least one of the side panels 110 has a length that is less than that of the other side panels 110.
Generally, the electrically insulative cover 100 shown in FIGS. 3-6 has a top panel 105 and at least one side panel 110. The side panels 110 may be coupled to the top panel 105 and the other, if present, side panels 110 by adhesives or other proper securement mechanisms. If the cover 100 is pieced together in this fashion, the securement mechanism, whether mechanical or chemical in nature, must be able to withstand the high voltage environment of the meter pan 200. For this reason, it is preferable that the cover 100 is formed from a continuous piece of material. The material chosen must be resistant to the aforementioned high voltage environments in the meter pan 200 or elsewhere. Preferably, this material is a rubber which may include, but is not limited to, natural rubber, styrene-butadiene rubber (SBR), Isoprene rubber, Butadiene rubber, and (poly)chloroprene rubber and the like or any combination thereof. Preferably, the rubber choice is a silicone-based rubber.
The overall shape and appearance of the electrically insulative cover 100 may vary as with its intended purpose. As shown in FIGS. 2-3, the electrically insulative cover 100 preferably covers one (1) or two (2) line lugs 230 at once as one is to be most concerned about the line lugs 230. Thus, the shape may vary depending on the amount of line lugs 230 covered or the amount of extraneous electrical apparatus that is covered as well.
Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the scope of the invention.
