(10) FIG. 1A illustrates a top view of an exemplary multi-point junction 100 according to an illustrated embodiment of the subject application. The multi-point junction 100 includes two or more female junction well interfaces 102 that are coupled to, or otherwise extend from, a base plate 104 (FIG. 1C) of the multi-point junction 100. While the exemplary multi-point junction 100 illustrated in FIG. 1 is a six-point junction that has six junction well interfaces 102, the number of female well interfaces 102, and thus the number of junction points, can vary for different applications. For example, according to certain embodiments, the multi-point junction 100 can be configured to have two to six well interfaces 102.

(11) Additionally, according to the illustrated embodiments, the plurality of well interfaces 102 of the multi-point junction 100 are each female contact interfaces that are configured to receive a mating male connector and/or accessory. According to certain embodiments, each of the well interfaces 102 have a generally uniform shape, size, and/or configuration so that each well interface 102 is configured to generally interchangeably receive the same sized and/or shaped mating male connector or interface. Additionally, as shown in at least FIG. 1A, according to certain embodiments, the interfaces 102 can be limited to female contact interfaces, and do not include any male connectors or interfaces. Moreover, as illustrated, the multi-point junction 100 does not include any male electrical connectors extending from the base plate 104, including, for example, any male loadbreak bushings, among other types of male electrical connectors or interfaces. For example, according to certain embodiments, the well interfaces 102 for the exemplary multi-point junction 100 are solely 600 Amp wells. Additionally, while each of the well interfaces 102 can be coupled to a male connector or interface that is associated with a variety of different types of electrical devices, components, and/or accessories, according to the illustrated embodiment, one of the plurality of well interfaces 102 is coupled to a male connector that is coupled to a power source that can provide electrical power to the multi-point junction 100, and thus power that is distributed via at least one or more components of the base plate 104 to at least the other well interfaces 102.

(12) Each of the well interfaces 102 can outwardly extend from an upper surface 106 (FIGS. 2A and 2C) of the base plate 104 from a first end 108 to a second end 110 of the well interface 102. According to the illustrated embodiment, at least the outer portion of the well interfaces 102 can have, for example, a generally cylindrical shape, among other shapes. Additionally, the well interfaces 102 can each include a first opening 112 at the first end 108, and a second opening 114 at the second end 110, of the well interface 102. Further, the first end 108 of the well interface 102 can be coupled to the base plate 104 in a variety of different manners. For example, according to certain embodiments, the first end 108 of the well interface 102 can be coupled to the base plate 104 via one or more mechanical fasteners, including, but not limited to, a bolt, screw, and/or pin, an interference or compression fit, an adhesive, and/or a combination thereof, among other manners of securely coupling the first end 108 of each of the well interfaces 102 to the base plate 104.

(13) As shown by at least FIG. 1B, each well interface 102 can include an outer jacket 116 and an inner insulative jacket 118. The outer jacket 116 can be formed or molded from a variety of different types of materials, including, for example, a conductive (or semi-conductive) peroxide-cured synthetic rubber, commonly referred to as EPDM (ethylene-propylene-dienemonomer), among other materials. An inner wall 120 of the outer jacket 116 can define an area in which at least a portion of the insulative jacket 118 is housed within the well interface 102. Additionally, an inner wall 122 of the insulative jacket 118 can define at least a portion of a cavity 124 of the well interface 102, and be shaped to provide a female contact interface that is shaped and positioned to generally mate and/or confirm to the configuration of a mating male connector or interface. For example, according to certain embodiments, the inner wall 122 of the insulative jacket 118 may be outwardly tapered from the first end 108 to the second end 110 of the well interface 102 such that the inner configuration of the female contact interface of the well interface 102 corresponds to the mating taper of a male interface of a loadbreak bushing. According to such an embodiment, the degree and length of taper of the inner wall 122 of the insulative jacket 118 can be based on a variety of different considerations, including, but not limited to, the configuration of the mating exterior portion of the loadbreak bushing and/or power line that will be inserted into the into the cavity 124 through the second opening 114 of the well interface 102, and/or one or more associated industry, manufacturer, and/or customer standards, including, but not limited to, one or more standards as set forth by the American National Standards Institute (ANSI). Further, the insulative jacket 118 can be formed or molded from a variety of types of insulating materials, including, but not limited to, rubber, synthetic rubber, plastic, and/or EPDM, among other materials.

(14) The base plate 104 can be constructed form a variety of different materials. For example, as shown in at least FIG. 2B, the base plate 104 can comprise a bus bar 126 that is constructed from an electrically conductive base material, such as, for example, copper, brass, or aluminum, among other materials. Additionally, the base plate 104 can include an outer insulative layer 128 that comprises an electrical insulative material, such as, for example, rubber, among other materials. According to certain embodiments, the outer insulative layer 128 of the base plate 104 can be applied to the bus bar 126 such that the outer insulative layer 128 coats and/or encases at least a portion of the bus bar 126 within the insulative layer 128.

(15) Additionally, or optionally, as shown in FIGS. 1A and 1C, according to certain embodiments, the base plate 104 can be housed within an outer housing 130 that can be configured to prevent accidental contact with the base plate 104 and/or bus bar 126. The outer housing 130 can be constructed from a generally electrically non-conductive and/or insulative material. According to certain embodiments, the outer housing 130 includes an upper plate 132, a first flange 134, and a second flange 136. The first and second flanges 134, 136 can be coupled to opposing sides of the upper plate 132. Further, according to certain embodiments, the first and second flanges 134, 136 can have generally L shaped configuration such that a flange plate 138 of the first and second flanges 134, 136 is positioned below, or offset from, the upper plate 132. The configuration of the first and second flanges 134, 136 can be designed to prevent accidental contact with at least side portions of the base plate 104 and/or sides of the bus bar 126.

(16) One or both of the first and second flanges 134, 136 can include an attachment member 140 that is configured to secure the multi-point junction 100 to another structure, component, and/or wall. For example, according to the embodiment depicted in FIG. 1, the attachment member 140 can comprise a plurality of through holes that extend through the first flange 134 and/or the second flange 136 that are sized to receive a mechanical fastener, such as, for example, a bolt, screw, pin, and/or hook, among other fasteners, that are used to generally secure the multi-point junction 100 to another structure. Alternatively, the attachment member 140 can be a mechanical fastener, such as, for example, a bolt, screw, pin, or nut, among other types of mechanical fasteners.

(17) Each well interface 102 can also include a well stud 142 that can threadingly engage a mating fastener or bolt of the male electrical component that will be inserted into the cavity 124. For example, according to certain embodiments, the well stud 142 can include an external or internal thread that mates with a corresponding internal or external thread of the male electrical component or interface that will be electrically coupled to the well interface 102. More specifically, according to certain embodiments, the well stud 142 of at least some of the well interfaces 102 includes an external thread that mates an internal thread of a bushing bolt of a male loadbreak bushing. The well stud 142 can be constructed from an electrically conductive material such that electrical power can be communicated from the bus bar 126 through at least the well stud 142 and to the associated male electrical component, device, or accessory, or vice versa, that is coupled to the well stud 142.

(18) As shown by a least FIG. 2A, the base plate 104 can include at least one orifice 144 that extends through the base plate 104, and moreover, through the bus bar 126, that is configured to both accommodate passage of the well stud 142 through the bus bar 126, as well as provide an interface for the well stud 142 to be in electrical communication with the bus bar 126. According to certain embodiments, the orifice 144 can have an internal thread that is configured for mating engagement with the external thread of the well stud 142. Additionally, the bus bar 126 can also include a counter bore 146 that is sized to receive recessed placement of at least a portion, if not all, of a head 148 of the well stud 142 within the bus bar 126. According to certain embodiments, such a configuration may allow a surface of the head 148 of the well stud 142 to directly or indirectly abut, and thus be in electrical communication with, an adjacent surface of the bus bar 126. For example, according to certain embodiments, an electrically conductive washer or spacer can be positioned inbetween, and electrically coupled to both, the bus bar 126 and the head 148 of the well stud 142.

(19) According to certain embodiments, the well stud 142 can also be coupled to the well interface 102. For example, according to certain embodiments, the first opening 112 at the first end 108 of the well interface 102 can include an internal thread that mates the external thread of the well stud 142. Alternatively, according to certain embodiments, the well interface 102 can include a nut or other mating connector or fastener that can securely engage the well stud 142. Yet, according to other embodiments, the well stud 142 can project through the first opening 112 and into the cavity 124 without being directly fastened to the well interface 102, and instead be only securely coupled to the base plate 104 prior to mating engagement with a male connector or interface that is received with in the cavity 124 of the well interface 102.

(20) In addition to being configured to have a variety of different number of well interfaces 102, the well interfaces 102 and/or associated well studs 142 can be separated at a variety of different distances from neighboring well interfaces 102 and/or associated well studs 142. For example, FIG. 2A illustrates an exemplary multi-point junction 100 having six well interfaces 102 that are spaced apart such that the center line(s) of the well interfaces 102 and/or associated well studs 142 are approximately six and one-half inches (6.5 inches) apart. According to the illustrated embodiment, the female well interfaces 102a, 102b at opposing ends of the multi-point junction 100 are, or are almost, flush with the adjacent end 150a, 150b of the base plate 104. However, according to other embodiments, the end female well interfaces 102a, 102b can be inwardly offset by a greater distance from adjacent ends 150a, 150b of the base plate 104, as shown, for example, by FIG. 1A. FIG. 2C illustrates a multi-point junction 100 that is similar to that depicted in FIG. 2A with the exception that the center line(s) of the well interfaces 102 and/or associated well studs 142 are approximately four inches (4 inches) apart. Thus, according to the exemplary embodiment depicted in FIG. 2C, as the end female well interfaces 102a, 102b are, or are almost, flush with the adjacent end 150a, 150b of the base plate 104, the overall linear length of the base plate 104 for the embodiment depicted in FIG. 2C is shorter than that depicted in FIG. 2A.

(21) With each of the well interfaces 102 being female contact interfaces, the construction of the multi-point junction 100, 100 can be simplified while also providing a degree of modularity that can improve the ease with which the multi-point junction 100, 100 can be adapted to conform to the different demands of different applications and/or different end users. For example, according to the illustrated embodiment, adapters can be available that can interchangeably mate with any one of the well interfaces 102 of the multi-point junction 100, 100. For example, upon providing a multi-point junction 100, 100, interface adapters can be made available that fit into any of the interface wells 106. Such adapters can include, but are not limited to, adapters to provide a lower amperage connection, such as, for example, a well adapter that can reduce a 600 amp well interface 102 to a 200 amp interface at the well adapter. Additionally, interface adapters that can matingly engage the interface wells 106 can also include 15 kilovolt (kV) and 25 kV loadbreak interfaces, as well as both male and female 600 amp interfaces.
