The present invention relates to an electrical extension cord device, such as an AC electrical extension cord device having an electrical port.

Background

Us D684,929 discloses an AC port. There is a need for an electrical extension cord device having an electrical port, such as an AC port).

Disclosure of Invention

The invention relates to an electrical extension cord device. For example, an electrical extension cord device according to the present invention includes an electrical port. For example, the electrical port may be provided with a removable cap or cover. The electrical port is provided with a receiver that receives an electrical connector (e.g., an electrical plug, an electrical socket). The electrical extension cord device also includes an electrical wire or cable that connects the electrical port to an electrical connector (e.g., electrical socket, electrical plug). The electrical wire or cable is sufficiently long to allow the electrical port to be separated from the electrical connector by at least a predetermined distance (e.g., two (2) feet to 200 feet or more). For example, the wire or cable may be at least 10 feet, 25 feet, 50 feet, 75 feet, 100 feet, and over 100 feet long, or 2 meters, 4 meters, 6 meters, 8 meters, 10 meters, and over 10 meters).

For example, the electrical port and the removable cap or cover are configured to provide a watertight seal between the electrical port and the removable cap or cover when the removable cap or cover is installed "on" the electrical port to prevent water or moisture from entering the receptacle of the electrical port. The electrical port includes a flange surrounding a receptacle of the electrical port.

An enhanced water-tight seal is achieved by providing a raised annular ridge having a raised flat annular surface on the front face of the flange of the electrical port. Specifically, the annular ridge is raised a predetermined distance above the front face surface of the electrical port. This arrangement reduces the size of the sealing area of the flat annular surface of the annular ridge to concentrate the sealing force between the cap or lid and the annular ridge to a smaller sealing area. In addition, the inner and outer edges of the annular ridge may be pressed into the soft or resilient material of the cap or lid, such that the inner and outer edges of the annular ridge seal the cap or lid more effectively with the annular ridge.

An electrical connector (e.g., an electrical socket) is connected to the electrical port by a wire or cable. An electrical connector may be provided with one or more protrusions to enhance a user's ability to grip and connect or disconnect the electrical connector with another electrical connector. For example, an X-shaped protrusion may be provided to allow a user to grasp the electrical connector with his or her fingers to connect or disconnect the electrical connector from another connector.

Detailed Description

An electrical extension cord arrangement 10 according to the present invention is shown in fig. 1-8.

Electrical extension cord apparatus 10 includes an electrical port 12 having a flange 14 secured to a housing 15. The housing 15 is provided with a receptacle 16 defined by a cylindrical wall 18 and a bottom wall 20. The cylindrical wall 18 is provided with a lower drain hole 18a (fig. 1 and 7) for venting the receiver 16 and draining any water or moisture located within the receiver 16 that drains by gravity to the lowest point in the receiver 16.

The flange 14 is provided with an outer surface 14a and through holes 14b (fig. 1), the through holes 14b for receiving fasteners (e.g., screws, rust-resistant screws, stainless steel screws, anodized aluminum screws) for mounting the electrical port 12 into a hole provided in a wall or plate, for example.

The receiver 16 houses, for example, a male electrical connector, such as an electrical plug 22 (i.e., a male electrical connector), the electrical plug 22 having a neutral pin 22a, an active pin 22b and a ground pin 22c extending outwardly from the inner bottom wall 20 into the receiver 16. The housing 15 of the electrical port 12 is provided with a wire sleeve 24 (fig. 3), the wire sleeve 24 having a groove 24a for making the wire sleeve 24 flexible or bendable. The wire sleeve 24 may be, for example, a plastic injection molded sleeve that fits over the wire or cable 42 and connects to the housing 15 of the electrical port 12 (e.g., a snap fit, interference fit, mechanical fit, or adhesive fit).

A gasket 28 having an inner cylindrical bore (e.g., a flat flexible gasket injection molded of resilient plastic) is mounted on the housing 15 on the rear side surface of the flange 14. For example, the gasket 28 fits between the flange 14 and the wall surface on which the electrical port device 14 is mounted. The gasket 28 comprises a ring 28a, a flexible connector 30 and a cap or cover 32, the cap or cover 32 having tabs 34 and a cylindrical collar 36, the cylindrical collar 36 being provided with an outer annular sealing ridge 38. The cylindrical collar 36 is provided with an internal cylindrical cavity 36a for receiving the electrical plug 22 when the cap or cover 32 is mounted "on" the electrical port 12. The flexible connector 30 is sufficiently flexible that the flexible connector 30 can be bent over 180 ° to mount the cap or cover 32 "on" the receiver 16, thereby sealing the receiver from water. To remove the cap or cover 32, a user may grasp the tab 34 to pull and remove (i.e., unload) the cap or cover 32 from the receptacle 16.

The electrical extension cord device 10 also includes an electrical connector, such as an electrical receptacle 40 (i.e., a female connector). The electrical receptacle 40 may be, for example, a plastic insert injection molded receptacle having electrical conductors, including a neutral pin receptacle 40a, an active pin receptacle 40b, and a ground pin receptacle 40 c. The electrical receptacle 40 is connected to a three (3) wire cord 42, the three (3) wire cord 42 electrically connecting the electrical receptacle 40 to the electrical port 12 of the electrical extension cord apparatus 10.

The electrical connectors 22, 40 in the electrical extension wire apparatus 10 can be varied or altered, respectively, to provide female and male electrical connectors, rather than the male and female electrical connectors 22, 40 shown in the figures.

The electrical receptacle 40 includes an X-shaped projection 40d and a wire cover 40e having a slot 40f to make the wire cover 40e flexible or bendable. The X-shaped projections 40d allow a user to firmly grasp the electrical receptacle 40 at the surface 40g on both sides of the electrical receptacle 40 using his or her fingers and thumb and then push or pull, remain stationary at the electrical receptacle 40 to connect or disconnect, respectively, the electrical receptacle 40 with another electrical connector (e.g., a plug).

Waterproof receiver

It is important and necessary to make the receiver 16 waterproof and to keep the receiver 16 and the plug 22 free of water and moisture to avoid the user from being accidentally shocked by an electrical short when connecting or disconnecting the plug 22, as shown in fig. 1. Thus, it is important that the cap or cover 32 properly seal with the flange 14 of the electrical port 12. In addition, in the event that water or moisture enters or condenses within the receptacle 16, it is important that the receptacle drains such water or moisture through the drain. Thus, the receptacle 16 is provided with a drain 18a (e.g., a drain hole) at the lowest point within the receptacle 16 so that water or moisture drains by gravity flow.

To properly seal the receiver 16 from water, the flange 14 is provided with a circular ridge 14c, the circular ridge 14c having an inner diameter D1 (fig. 1) equal to or the same as the diameter D1 of the receiver 16 and an outer diameter D2 that is greater than the inner diameter D1 of the circular ridge 14c, and D2 is less than the outer diameter D3 of the flange 14. The flange 14 is also provided with a radial ridge 14d extending radially outwardly from the outer edge of the circular ridge 14 c. A pair of ridges 14d are positioned adjacent the sides of each through hole 14b (fig. 2).

The circular ridge 14c is provided with a flat sealing surface 14ca (fig. 1). The circular ridge 14c is raised above the outer surface 14a of the flange 14 by a predetermined height. In addition, the radial ridge 14d rises above the outer surface 14a of the flange 14 by a predetermined height that is less than the predetermined height of the circular ridge 14 c. This arrangement allows the inner circular flat sealing surface 32a of the cap or cover 32 to seat only with the flat surface 14ca of the circular ridge 14c to ensure a good seal therebetween. In particular, this flat-to-flat sealing arrangement between the circular flat sealing surface 32a of the cap or cover 32 and the flat surface 14ca of the flange 14 of the electrical port 12 enhances the sealing and waterproofing capabilities of the receiver 16 and the plug 22 to keep water and moisture out of the receiver 16 and the plug 22.

In addition, the annular ridge 38 of the cap or lid 32 is sized (e.g., a predetermined diameter) and designed (e.g., a particular profile or cross-sectional shape of the ridge 38) such that the outer edge of the ridge 38 fits snugly and resiliently into the inner edge of the receiver 16. For example, a plurality of ridges 38 (e.g., two or more ridges) are used to provide a plurality of sealing engagements with, for example, the smooth inner cylindrical sealing surface 18 of the receiver 16. For example, the annular ridge 38 may have a square or rectangular profile to provide a flat arcuate sealing edge that sealingly engages the smooth inner cylindrical sealing surface 18 of the receiver 16.

Additionally, the housing 15 and flange 14 of the electrical port 12 may be injection molded from a rigid or semi-rigid plastic material, and the cap or cover 32 may be molded from a softer and/or more resilient plastic or rubber material, such that the smooth inner cylindrical sealing surface 18 applies a band-like stress to the annular outer edge 38a of the ridge 38 to improve the sealing strength of the cap or cover 32 mounted "on" the flange 14 of the electrical port 12 of the electrical port device 10.

The cap or cover 32 and the annular ridge 38 may be designed such that a retaining/sealing force is created between the ridge 38 and the inner cylindrical surface 18 of the receiver 16 to tightly seal and retain the cap or cover 32 within the receiver 16. In addition, the retention force applies a sealing force between the sealing surface 38a of the cap or cover 38 and the flat sealing surface 14ca of the circular ridge 14c of the flange 14 of the electrical port 12 of the electrical port device 10.

For example, cap or cover 38 may be made of a resilient plastic or rubber material such that when collar 36 of cap or cover 32 is fully inserted into receiver 16, the user may press the center of cap or cover 32 with his or her finger or thumb to further insert collar 36 into receiver 16 such that collar 36 exerts a resilient retention force on cap or cover 32 that exerts a resilient sealing force between inner circular flat sealing surface 32a of cap or cover 32 and flat surface 14ca of circular ridge 14c to enhance the sealing force between inner circular flat sealing surface 32a and flat surface 14ca and then maintain the sealing force.

Electrical extension wire or cable

The electrical extension cord apparatus 10 includes an electrical extension cord or cable 42. An extension cord or cable may be configured with two (2), three (3), four (4) or more conductors, such as insulated conductors. For example, electrical extension cord apparatus 10 includes an active wire, a neutral wire, and a ground wire. Additionally, the electrical extension or cable 42 may include multiple sets of wires (e.g., two (2) three wire sets). Additionally, the electrical port may be provided with a plurality of electrical connectors (e.g., two or more plugs, two or more sockets, one or more power bars), and the electrical connectors may include a plurality of connectors (e.g., two or more plugs, two or more sockets). Still further, the electrical extension cord device may include a fuse, a switch, one or more LEDs (e.g., illuminated when in a power "on" mode, with a red LED indicating a power "on" mode), or an LED that provides nighttime illumination (e.g., a ribbon LED) or flashing features.

The wire or cable connector 50 is provided with a protrusion 50d to enhance gripping of the wire or cable connector between the user's fingers and/or thumb.

The electrical connectors (e.g., electrical receptacle 40) are made, for example, of a resilient plastic material that is injection molded with the electrical conductors 40a, 40b, 40c (e.g., neutral, active, ground).
