Patent Application
20080024264
While the inventions disclosed herein are susceptible to various modifications and alternative forms, only a few specific embodiments have been shown by way of example in the drawings and are described in detail below. The figures and detailed descriptions of these specific embodiments are not intended to limit the breadth or scope of the inventive concepts or the appended claims in any manner. Rather, the figures and detailed written descriptions are provided to illustrate the inventive concepts to a person of ordinary skill in the art as required by 35 U.S.C. § 112.
One or more illustrative embodiments incorporating the invention disclosed herein are presented below. Not all features of an actual implementation are described or shown in this application for the sake of clarity. It is understood that the development of an actual embodiment incorporating the present invention, numerous implementation-specific decisions must be made to achieve the developer's goals, such as compliance with system-related, business-related and other constraints, which vary by implementation and from time to time. While a developer's efforts might be complex and time-consuming, such efforts would be, nevertheless, a routine undertaking for those of ordinary skill in the art having benefit of this disclosure.
Referring to
Electrodes 122 are deposited onto the two face surfaces 124, generally flat, of the disc-shaped ceramic inner core 120. There are several ways to deposit the electrodes 122 on the surfaces 124 of the inner core 120. One way is to depositing a thick film silver over the surfaces 124 of the inner core 120. Another way to deposit the electrodes 122 is by arc spraying metal materials such as aluminum and copper. As described in more detail below, the electrodes 22 are preferably placed on most if not all of the surfaces 124 of the inner core 120. This allows greater spacing between the two electrical leads 126.
Electrical leads 126 are then soldered to the electrodes 122 on each side of the inner core 120 with a soldering material at attachment points 128. Alternatively, the electrical leads 126 may be attached with a conductive adhesive known to those skilled in the art. Unlike the prior art, however, the electrical leads 126 are not attached to the center region 132 of the disc-shaped inner core 120. Instead, as shown in
Finally, an epoxy-based coating 130 is then applied to the outer surfaces of the assembly of inner core 120, electrodes 122, and electrical leads 126. In normal operation of the MOV 110, the coating 130 minimizes the cracking of the inner core and maintains the assembly of the inner core 120, electrodes 122, and electrical lead wires 126.

While the foregoing is directed to various embodiments of the present invention, other and further embodiments may be devised without departing from the basic scope thereof Other embodiments within the scope of the claims herein will be apparent to one skilled in the art from consideration of the specification and practice of the invention as disclosed herein. It is intended that the specification, together with the example, be considered exemplary only, with the scope and spirit of the invention being indicated by the claims which follow.
The various methods and embodiments of the invention can be included in combination with each other to produce variations of the disclosed methods and embodiments, as would be understood by those with ordinary skill in the art, given the understanding provided herein. Also, various aspects of the embodiments could be used in conjunction with each other to accomplish the understood goals of the invention. Also, the directions such as “top,” “bottom,” “left,” “right,” “upper,” “lower,” and other directions and orientations are described herein for clarity in reference to the figures and are not to be limiting of the actual device or system or use of the device or system. Unless the context requires otherwise, the word “comprise” or variations such as “comprises” or “comprising”, should be understood to imply the inclusion of at least the stated element or step or group of elements or steps or equivalents thereof, and not the exclusion of a greater numerical quantity or any other element or step or group of elements or steps or equivalents thereof The device or system may be used in a number of directions and orientations. Further, the order of steps can occur in a variety of sequences unless otherwise specifically limited. The various steps described herein can be combined with other steps, interlineated with the stated steps, and/or split into multiple steps. Additionally, the headings herein are for the convenience of the reader and are not intended to limit the scope of the invention.
Further, any references mentioned in the application for this patent as well as all references listed in the information disclosure originally filed with the application are hereby incorporated by reference in their entirety to the extent such may be deemed essential to support the enabling of the invention. However, to the extent statements might be considered inconsistent with the patenting of the invention, such statements are expressly not meant to be considered as made by the Applicant(s).
