Description

FIELD OF THE INVENTION

The present invention relates to convenience interface devices or panel interfaces. More particularly, but not exclusively, the present invention relates to such a device with a magnetically sealing cover.

BACKGROUND

The present invention relates to products that are often known as convenience interfaces or panel interfaces. A convenience interface provides a convenient method for personnel to access devices that reside inside an enclosure without opening the enclosure door. These devices can include: (1) control devices with data ports, (2) network access ports, and (3) human interface ports such as for a computer mouse or keyboard, (4) various I/O devices, (5) data storage devices, and (6) programmable devices. The convenience interface sometimes contains various types of electrical power outlets so that personnel can also power their programming device from the same location as the convenience interface. Various equipment, machines, or facilities have control panels that contain one or more of the types of devices described above. Installing a convenience interface with a power outlet and an interface for all the applicable devices inside the control panel allows personnel to perform maintenance without opening the panel door thereby reducing their exposure to the hazardous voltage inside the enclosure. Various control panels are built with a separate power outlet mounted on the inside of the enclosure to provide power for the personnel working inside the panel, the separate power outlet being independent of the convenience interface. The separate power outlet mounted on the inside of the enclosure may include a Ground Fault Circuit Interrupter (GFCI). Additional information about convenience interfaces is disclosed in U.S. Pat. No. 6,700,062, hereby incorporated by reference in its entirety.

One potential issue with such interface devices is that because they are mounted to a panel exterior they are exposed to environmental conditions which may potentially include water or other contaminants which may have an adverse effect on the interface device and potentially leading to shorts. To address this issue, such devices may have a cover which seals with the main body of the housing. When the device is not being used, the cover is supposed to be securely clamped in place. Issues may be created, however, through human error if individuals working with the device do not follow proper procedures and fail to secure the covers in place. What is needed is an improved convenience interface device.

SUMMARY

Therefore, it is a primary object, feature, or advantage of the present invention to improve over the state of the art.

It is a further object, feature, or advantage of the present invention to provide a housing for convenience interface devices which includes a cover.

It is a still further object, feature, or advantage of the present invention to provide a convenience interface device with a cover that provides for closing in a manner to provide at least some protection against water or other contaminants even when an individual fails to properly follow proper procedures.

FIG. 1 illustrates a convenience interface mounted to a control panel cabinet with the cover removed.

FIG. 2 illustrates a cover assembly for a convenience interface, the cover assembly including a cover and a cover receiving frame.

FIG. 3 illustrates an outside face of an assembly of a convenience interface.

FIG. 4 illustrates an inside face of an assembly of a convenience interface.

DETAILED DESCRIPTION

FIG. 1 illustrates one example of a convenience interface device 10 which may be mounted to a control panel cabinet 12. The convenience interface device 10 includes a housing 13 with an outside face and various outlets or connectors may be mounted to the outside face. There may be an inside face opposite the outside face and one or more connectors may also be present on the inside face. What is shown is merely representative. The present invention contemplates that any number of types of different inside faces and opposite outside faces and any number of different connectors may present such as those present on GracePort® convenience interfaces available from Grace Engineered Products, Inc.

FIG. 2 illustrates a cover assembly 14 which may be used on a convenience interface device similar to that shown in FIG. 1. It is to be understood that the convenience interface device may be of different sizes and shapes but is often generally rectangular. The cover assembly 14 has a cover receiving frame 20 for receiving a cover 22. A plurality of magnets or metal inserts 26 are positioned around an outer annular portion of the cover to magnetically connect with a plurality of metal inserts or magnets 28 positioned around an outer annular portion of the cover receiving frame 20. Although two magnets or metal inserts 26 are shown to magnetically couple with two metal inserts or magnets 28, it is to be understood that more or fewer may be present in a particular design. It is to be further understood that each metal insert may magnetically couple to a magnet and each magnet may magnetically couple to a metal insert.

It is also to be understood that the magnets may be positioned around the holes for the screws. Screws (not shown) may be positioned through the cover 22 and into a threaded insert mount below the magnet. Where a metal insert is used it may be the thread insert for the screws from the lid. Thus, the cover may be secured in two different ways. First, in a closed position only the magnets may be used for closing the cover. This type of closure is not ideal and so may only maintain a minimal environment rating, however this closure still offers significantly more protection than the situation where the cover is left unsealed. Second, the cover 22 may be screwed into the cover receiving frame 22 to fully secure the cover in place in a securely closed position. When the cover 22 is screwed into the cover receiving frame 22 a fully secured fit is maintained to protect against the environment including water or other liquids or other contaminants.

When sealed a member 30 of the cover 22 may engage with a portion 32 of the cover receiving frame 20 in order to provide a tighter fit or seal of the cover 22 and the cover receiving frame 20. Sealing gaskets may also be present to assist in forming a tight seal.

As shown in FIG. 2, a hinge 24 is present. Any number of different types of hinges may be present. Instead of using a hinge, additional sets of holes, magnets, and screws may be added in order to secure the cover in place.

The cover may be made of any number of types of materials. In some embodiments, the cover may be made of a see-through material so that an individual may see the type of connectors present on the interface device without removing the cover.

FIG. 3 illustrates an assembly 40 removed from the convenience interface housing in which it is generally disposed, the assembly 40 has an inside face and an outside face 42 opposite the inside face, the inside face for being enclosed within the enclosure, the outside face 42 for being outside of the enclosure. The outside face 42 may include an outside power outlet 44 which includes female plug receptacles. The outside power outlet 44 is preferably a standard outlet such as a NEMA 5-15R or NEMA 5-20R. Of course, any number of different types of power outlets may be used such as may be standard in a particular country or otherwise desirable to use. The outside power outlet is accessible from outside of the enclosure. Also shown in FIG. 3 is a test button 46, a reset button 48, and an indicator 50 such as an LED. Other ports or interfaces may be present such as data interfaces including network interfaces, serial interfaces, or other types of interfaces.

FIG. 4 illustrates the assembly 40 with the inside face 52. The inside face 52 has an inside power outlet 54 which includes female plug receptacles. The inside power outlet 54 is preferably a standard outlet such as a NEMA 5-15R or NEMA 5-20R. Of course, any number of different types of power outlets may be used such as may be standard in a particular country or otherwise desirable to use. A plurality of apertures 56, 58, 60 are shown for power line connections. Each power line may be secured with finger safe screws (not shown) inserted into the corresponding one of the apertures.

Therefore, a convenience interface has been shown and described. The invention is not to be limited to the particular embodiments described herein.
