A bonding lug assembly includes a bonding lug and a set screw. The bonding lug includes a body that defines a first channel and a second channel. The first channel defines a first conductor path extending in a first direction, and the second channel defines a second conductor path extending in a second direction that is different from the first direction. The set screw is configured to selectively engage the bonding lug and retain a bonding conductor within at least one of the first channel or the second channel.

DETAILED DESCRIPTION

(16) The subject matter of embodiments of the present invention is described here with specificity to meet statutory requirements, but this description is not necessarily intended to limit the scope of the claims. The claimed subject matter may be embodied in other ways, may include different elements or steps, and may be used in conjunction with other existing or future technologies. This description should not be interpreted as implying any particular order or arrangement among or between various steps or elements except when the order of individual steps or arrangement of elements is explicitly described. Directional references such as “up,” “down,” “top,” “bottom,” “left,” “right,” “front,” and “back,” among others, are intended to refer to the orientation as illustrated and described in the figure (or figures) to which the components and directions are referencing.

(17) FIGS. 1-14 illustrate an example of a bonding lug assembly 100 according to aspects of the current disclosure. The bonding lug assembly 100 includes a first conductor path and a second conductor path such that the bonding lug assembly 100 can be utilized in a plurality of locations and in a plurality of orientations without requiring a different style of lug. The bonding lug assembly 100 may be utilized with an equipotential bonding system to connect various items to a bonding conductor (e.g., bonding wire). The bonding lug assembly 100 includes a bonding lug 102 and a set screw 104.

(18) As illustrated in the figures, the bonding lug 102 includes a body 106 and a mounting flange 108. The mounting flange 108 defines a mounting aperture 114 that is configured to receive a mounting mechanism (e.g., a screw, pin, etc.) such that the bonding lug 102. can be secured to a component to be bonded or joined as part of the equipotential bonding system. In some optional examples, the mounting flange 108 includes a gripping portion 116 that facilitates positioning of the bonding lug 102 on the component to be bonded. The gripping portion 116 may include ridges defined in the mounting flange 108, other types of gripping features defined in the mounting flange, and/or various other suitable components attached to the mounting flange 108 that may facilitate positioning of the bonding lug 102. In some cases, the gripping portion 116 may facilitate positioning of the bonding lug 102 by increasing an amount of friction and/or surface area between the bonding lug 102 and the component to be bonded.

(19) The body 106 of the bonding lug 102 includes a set screw support 110 and a guide 112. The body 106 may be constructed from various suitable materials for bonding applications including, but not limited to, copper, aluminum, or other suitable materials or combinations of materials. The body 106 includes a front end 111, a back end 113 opposite the front end 111, a top side 115, and a bottom side 117 opposite the top side 115. A base 131 extends from the front end 111 to the back end 113. The set screw support 110 includes a forward-most edge 119 relative to the front end 111 of the body 106, and the guide 112 includes a forward-most edge 121 relative to the front end 111 of the body 106. The set screw support 110 defines a set screw aperture 118 that is configured to receive the set screw 104 when the bonding lug assembly 100 is assembled. As best illustrated in FIGS. 1, 2, and 5, the body 106 includes a first channel 120 between the set screw support 110 and the guide 112. The first channel 120 defines a conductor path extending in a first direction 122. As best illustrated in FIGS. 1-3 and 5, the body 106 also includes a second channel 124 that extends through the set screw support 110 and through the guide 112 and defines a conductor path extending in a second direction 126 that is different from the first direction 122. In some examples, the second direction 126 is coplanar with the first direction 122, although it need not be in other examples. In various cases, the second direction 126 is substantially perpendicular to the first direction 122, although it need not be in other examples.

(20) As illustrated in FIG. 5, in some examples, the set screw aperture 118 is defined in the set screw support 110 such that the set screw 104 positioned in the set screw aperture 118 can engage a bonding conductor in the first channel 120 and/or the second channel 124. In some cases, the set screw aperture 118 is aligned with the intersection of the first channel 120 and the second channel 124, although it need not be in other examples. In various aspects, the same set screw 104 can be utilized to connect to the bonding conductor in the first channel 120 and/or the second channel 122. In some optional examples, the set screw aperture 118 extends substantially perpendicular to the first channel 120 and the second channel 124, although it need not in other examples. In various cases, the set screw aperture 118 extends above the first channel 120 and the second channel 124, although it need not in other examples.

(21) FIGS. 10-12 illustrate the set screw 104. While a set screw 104 is illustrated, it will be appreciated that various other suitable mechanisms for securing the bonding lug assembly 100 to a bonding wire may be utilized, including, but not limited to, pins, rods, bolts, etc.

(22) FIG. 13 illustrates an example of a bonding wire 128 positioned in the first channel 120, As illustrated in FIG. 13, the bonding wire 128 is retained in the first channel 120 with the set screw 104. FIG. 14 illustrates an example of the bonding wire 128 positioned in the second channel 124. As illustrated in FIG. 14, the bonding wire 128 is at least partially retained in the second channel 124 with the set screw 104. In some cases, the bonding wire 128 may initially engage the bonding lug assembly 100 via the first channel 120 and leave the bonding lug assembly 100 via the second channel 124 (e.g., the bonding wire 128 may bend from the first direction 122 to the second direction 126 rather than extending along the first direction 122). In other words, the bonding lug 102 with the plurality of channels may be used in various locations when more than one path to the lug is required (e.g., in tight locations). By using the bonding lug assembly 100, the same bonding lug assembly 100 can be used to connect to the bonding wire 128 in various configurations or orientations.
