Flush earth ground connector

Abstract

This invention is a connecting device for earth grounding aircraft and aerospace equipment. The connector assembly has two parts, an upper and lower. The upper part of the connector provides a receptacle to secure an aerospace chassis ground wire. An internal magnet holds the upper part to the lower part. The lower part is secured in the ground and is flush with the surrounding surface. It is subterraneously connected to a ground rod. Upon disconnection and removal of the upper part, the lower part stays in place and provides a smooth and unencumbered surface.

5. The assembly according to claim 2, wherein: the bottom portion of the connector is mounted to an auger or screw type mount, or to the surrounding surface, or attached directly to a ground rod.

6. The assembly according to claim 2, wherein: a ground cable is welded, clamped, bolted, or otherwise secured to the bottom portion of the connector when not directly attached to a ground rod.

7. The assembly according to claim 1, wherein: the upper portion of the connector is of disk shape with a vertical handle that houses set screws to secure an aircraft, aerospace, or support equipment ground cable.

8. The assembly according to claim 7, wherein: the upper portion of the connector contains a magnet that produces enough attraction to secure it to the bottom portion of the connector but still allows removal by hand strength.

9. The assembly according to claim 7, wherein: the upper portion of the connector has sufficient metallurgical composition to be electrically conductive.

10. The assemblies according to claims 2 and 7, wherein: when brought together, forms an electrically conductive connection.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments of the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to practice the disclosure and are not intended to limit the scope of the appended claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding field, background, brief summary, or the following detailed description. Many modifications are conceivable without departing from the spirit of the inventive concept as defined in the appended Claims.

[0019] Note that the standard and universally accepted symbols for earth ground and chassis ground are used in FIG. 1 items 22 and 14 respectively.

[0020] As best illustrated in FIGS. 1 through 6, the flush earth ground connector generally comprises of two parts. An upper portion 10 and lower portion 19. Male and female connotation describing the connector parts does not apply due to the fact that the connecting bodies are flush and smooth as is the purpose of the embodiment. Therefore, upper portion and lower portion will be used to describe the two parts of the connector assembly 5. The upper portion 10 is attracted to the lower portion 19 by an internal magnet 18. The magnet 18 secures the upper 10 and lower portion 19 together to allow for electrical flow through the connector assembly 5.

[0021] The upper portion 10 is of cylindrical disk shape with a handle 15 of rectangular shape protruding from the top. The handle 15 contains and opening 13 to accept a standard aerospace static grounding wire 12. The grounding wire 12 is secured by two set screws 11 contained within the handle 15 of the upper portion. Upon insertion of the ground wire 12 the two set screws 11 are tightened to hold the wire 12 in place and allow for electrical conductivity. As shown in FIG. 4, an exploded view of the upper portion, of the present embodiment describes two separate components, an upper half 40 and lower half 41 that combine together through threading 43 to secure a magnet 18 internally.

[0022] The lower portion 19 of the connector is a semispherical, cylinder type shape. The top surface 26 of the lower portion is flat and sits flush with the surrounding surface 17. The flat surface 26 of the lower portion 19 allows for placement of the upper portion of the connector 10. The bottom of the lower portion 19 has a cylindrical hollowed space 27 to allow for mounting on to an auger 30. The lower portion 19 can also be mounted by alternative methods, not limited to but including, directly to an earth ground rod, a post, or otherwise secured to the surrounding surface 17. The lower portion 19 is connected to an earth ground 22 either directly or via cable 20 by securing it through a weld or clamp or similar attaching methods.

[0023] The coupled, flush earth ground connector 5 allows electrical static build up to be dissipated from the aerospace vehicle, equipment, or aircraft through the chassis connection 14, the aerospace ground wire 12, the upper portion of the connector 10, the bottom portion of the connector 19, the ground cable 20, to the earth ground rod 22. Upon removal of the upper portion of the connector 10, the bottom portion 19 remains flush with the surrounding surface 17 leaving the area free from protrusions or divots.
