DETAILED DESCRIPTION

The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide an understanding of the claimed subject matter. It is evident, however, that the claimed subject matter can be practiced without these specific details. In other instances, structures and devices are illustrated in block diagram form in order to facilitate describing the claimed subject matter. Relative size, orientation, etc. of parts, components, etc. may differ from that which is illustrated while not falling outside of the scope of the claimed subject matter.

Referring now to FIG. 1, a schematic view of a portion of an exemplary high voltage power electrical distribution system 100 is shown. The distribution system 100 as shown includes electrical support devices 102 (e.g., towers), however, any suitable support devices or structures can be used with the subject matter of the present disclosure. The towers are engineered and built to keep one or more electrical conductors 104 a desired separation distance from obstacles on the ground 106. The minimum separation distance is intended to be maintained throughout various conditions such as windstorms, high heat causing conductor sagging, high electrical demand times, etc. As is to be expected, there is a periodic need to connect the ends of electrical conductors 104 at their termination points to maintain an electrical circuit. The electrical distribution system 100 distribution enables transmission of electrical energy across relatively large distances.

Referring to FIG. 2, an example termination point 200 is shown where the electrical conductors 104 are connected to (e.g., placed into electrical communication with) one another through an exemplary electrical connector 202. In the shown example, an arm 204 extends from a main portion of the tower 102 (shown in FIG. 1), and supports an electrically insulating device 206. A lower portion of the electrically insulating device 206 can include structure 208 to support one or more electrical connectors 202. A jumper 210 can be provided to enable electrical communication between each of the electrical connectors 202, thus providing electrical communication between each of the electrical conductors 104. Similar to FIG. 1, the shown example of the arm 204, the electrically insulating device 206, the structure 208, and the jumper 210 are merely examples, and any suitable substitute structures can be used in conjunction with the present disclosure.

Referring to FIG. 3, a cross-section view of the electrical connector 202 is shown. The electrical connector 202 can also be termed a dead-end connector or a dead-end clamp, among other similar names that are known to one having skill in the art. The electrical connector 202 includes a compression device 300 that extends from a first end 302 to a second end 304 along a compression device central axis 306. The compression device 300 can be made of any suitable material that can withstand the physical and electrical requirements of typical electrical components in electrical distribution systems, yet provide reliable and repeatable results during compression operations as will be discussed below. In some examples, the compression device 300 is constructed of steel.

The second end 304 can include a loop, an eye 308, or an eyelet device used to connect the compression device to a support tower 102 (shown in FIG. 1) or similar electrical conductor support devices.

The first end 302 includes an outside diameter 310, and it also defines an aperture 312. the aperture 312 is defined by an inside diameter 314, and the inside diameter 314 of the aperture 312 is less than the outside diameter 310 of the first end 302. The aperture 312 is configured to accept a portion of an electrical conductor 104. Appropriate properties of the electrical conductor 104 will be discussed below. In some examples, the aperture 312 is a blind aperture, meaning that it is open to one end (i.e., the first end 302) and there is no opening at the opposite end (e.g., the second end 304 of the aperture 312. In another example, a center line of the aperture 312 is colinear with the central axis 306 of the compression device 300.

Referring to FIG. 4, a side view of the compression device 300 is shown. The compression device 300 can include a portion having surface features 400 that can include, but are not limited to, circumferential ridges, threads, etc. The surface features 400, can be designed and manufactured to tailor mechanical properties of attachment of the compression device 300 to another structure such as an outer tube that will be described below.

Referring to FIG. 5, a cross-section view of the compression device 300 is shown. In this example, and that of the compression device 300 in FIG. 4, an insert 500 can be located within the aperture 312. As with the surface features 400, the insert 500 can be designed and manufactured to tailor mechanical properties of extrusion and compression of the insert 500, the compression device 300, and the electrical conductor 104 during a compression operation that will be discussed below. While not necessary, the insert 500 can include more than one section, for example, the insert body 502, the insert cap 504, and the insert end 506. The insert 500 can also provide reliable and repeatable positive location of the electrical conductor 104 when the electrical conductor 104 is located within the aperture 312 prior to the compression operation.

Referring to FIG. 6, a termination point of an example electrical conductor 104 is shown. This particular electrical conductor 104 is a conductor having circular cross-section wires 600 or strands. This conductor, as is typical of many other conductors, includes a core 602 that is engineered to support the weight of the electrical conductor 104 as it hangs from distant support devices 102 (e.g., towers) in an electrical distribution system 100. In some examples, the core 602 includes seven strands of steel; six strands 604 surrounding one central strand 606.

A base row 608 of wires surrounds the core 602 and provides flexibility and protection for the core 602 while carrying a relatively small amount of electricity that passes through the electrical conductor 104. A top row 610 or rows typically carry the majority of the electricity, and the top row 610 surrounds the base row 608. Each of the wires or strands of the top row 610 and the base row 608 can be constructed of any suitable material. In some examples, the wires or strands are composed of aluminum. In some examples, the compression device 300 comprises a material having a hardness that is greater than a hardness of the base row 608 of wires. In some examples, the compression device 300 is constructed of steel. The

Referring to FIG. 7, the electrical conductor 104 is a conductor having trapezoidal circular cross-section wires 700 or strands. This type of conductor also includes a core 702 (e.g., a carbon core is shown), a base row 704, and a top row 706 or rows. In some examples, the core 702 can include a sheath 708. The shown example electrical conductor 104 including the trapezoidal wire 700 or strands can be beneficial in that there is less volume of space between the wires or strands (e.g., spaces between wires 700 in FIG. 7 versus wires 600 in FIG. 6), and the alignment of the wires 700 or strands is well-established without significant movement between the individual wires 700 or strands during a compression operation. Both the circular and the trapezoidal wires 600, 700 or strands can be produced through an aluminum extrusion process.

In some examples, as the one shown in FIG. 7, the core 702 is composed of carbon fibers. At times, the carbon fibers can include several strands, such as the steel example described in relation to the example shown in FIG. 6. In other examples, the carbon fiber can be a larger diameter, single-strand core 702.

The examples of FIGS. 6 and 7 both show a termination point of an example electrical conductor 104 where a portion of an exterior sheath (shown in FIG. 3) has been removed, and a portion of the top row(s) 610, 706 and the base row 608, 704 have been shortened in order to expose the core 602, 702 that will be placed in the aperture 312 of the compression device 300 in order to permanently attach the electrical conductor 104 to the compression device 300 in a compression operation.

Returning to FIG. 3, the inside diameter 314 approximates an outside diameter 316 of a base row of wires of the electrical conductor 104. This relationship between the inside diameter 314 and the outside diameter 316 enables the base row of wires to be relatively easily inserted in an axial direction (represented by arrow 318) to the aperture 312. In some examples, the inside diameter 314 can define a circular profile, but other cross-sectional profiles are also contemplated, such as an ovoid cross-section. The inside diameter 314 term is not meant to be limiting to a circular or cylindrical aperture.

The electrical connector 202 also includes an outer tube 320 having an outer tube central axis that can be colinear with the compression device central axis 306. The outer tube 320 defines a central through hole 322 configured to allow a portion of the compression device 300 to be placed within the outer tube 320. The outer tube 320 and the compression device 300 can be connected in any suitable manner. In some examples, the outer tube 320 and the compression device 300 are connected through a threaded connection.

It is worthy of note that the example electrical connector 202 shown in FIG. 3 does not include the insert 500 as shown in FIG. 5. In some examples, the insert 500 is beneficial to include, and the present disclosure can include examples of electrical connectors 202 with inserts 500 and without inserts 500. In some examples, the insert 500 is used in electrical connectors 202 that use only the core 602 within the compression zone for the compression device 300. In other examples, the insert 500 is not used in electrical connectors 202 that use the core 602 and the base row 608 of the electrical conductor 104.

Remaining with FIG. 3, a length 324 of the compression device 300 is configured to be compressed around the first end 302, the base row 608 of wires, and a core 602 of the associated electrical conductor 104 such that the compressed assembly locks the associated electrical conductor 104 within the compression device 300 such that the compression device 300 supports the electrical conductor 104 between electrical support devices 102. In other examples, the associated electrical conductor 104 is unable to be physically removed from the electrical connector 202. In yet other examples, the outer diameter 316 and the inner diameter 314 have a particular ratio or relationship that fosters a proper compression result.

Referring to FIG. 8, a length 800 of the compression device 300 is configured to be compressed around the insert 500 and the core 602 of the electrical conductor 104 such that the compressed assembly locks the associated electrical conductor 104 within the compression device 300 such that the compression device 300 supports the electrical conductor 104 between electrical support devices 102. In other examples, the associated electrical conductor 104 is unable to be physically removed from the electrical connector 202.

In examples as represented in FIG. 8, the electrical connector 202 includes the compression device 300 centered about the compression device central axis 306. The compression device 300 includes the first end 302 defining an aperture 312. The aperture is defined by an inside diameter 314. The compression device 300 comprises a first composition material. In some examples, the first composition material is steel.

The electrical connector 202 can also include an inner annular cylinder (e.g., insert 500), the cylinder defining a longitudinal passage 802 such that the cylinder has a cylinder outside diameter 804 and a cylinder inside diameter 806. The cylinder outside diameter 804 is configured to enable placement of the cylinder inside the aperture 312 of the compression device 300. The cylinder inside diameter 806 is configured to enable placement of the core 602 of the associated electrical conductor 104 within the cylinder. The cylinder comprises a second composition material, for example, aluminum.

The electrical connector 202 of FIG. 8 can also include an outer tube 320 as shown in FIG. 3 extending along an outer tube central axis that can be colinear with the compression device central axis 306. The outer tube 320 defining a central through hole 322, the central through hole 322 configured to allow a portion of the compression device 300 to be placed within the outer tube 320. Similar to the previous embodiment, a length of the outer tube 320 is configured to be compressed around the first end 302, the insert 500, and the core 602 of the associated electrical conductor 104 to form a compressed assembly such that the first composition material and the second composition material extrude axially at different rates. Additionally, the compressed assembly locks the associated electrical conductor 104 within the compression device 300 such that the compression device 300 supports the electrical conductor 104 between electrical support devices 102 and/or the electrical conductor 104 cannot be removed from the compressed assembly.

Referring to FIG. 9, the cylinder (e.g., insert 500) can further include a shoulder 900, the shoulder 900 is configured to cooperate with the compression device 300 to limit the length of the cylinder that can pass into the aperture 312. Additionally, the cylinder can be clocked with the aperture 312. In some examples, the shoulder 900 can define a void 902 that cooperates with a tab 904 on the compression device 300 to reduce or eliminate angular rotation of the cylinder about the axis 306. In this way, the cylinder can be positively located with respect to a rotational location within the aperture 312.

Referring to FIG. 10, an example set of jaws 1000 are shown surrounding a set of concentric circles 1002. The circles represent an end view (e.g., from the first end 302) of the electrical connector 202. Any of the previously described embodiments of electrical connectors 202 are intended to be represented in FIG. 10. The jaws 1000 are forced together in the direction of arrows 1004 to compress the compression area of the electrical connector 202 onto the electrical conductor 104 to lock them together. As shown in FIG. 10, the interior portion of the jaws are hexagonal in shape, and this is not intended to be limiting.

Referring to FIG. 11, a compressed assembly of the electrical connector 202 is shown taken along line 3-3 of FIG. 2. The electrical connector 202 is shown with an associated jumper 210 that provides electrical communication to the next electrical conductor 104.

Referring to FIG. 12, a perspective view of a portion of a compressed electrical connector 202 is shown. The electrical connector 202 has been compressed to form an unbreakable bond with the electrical conductor 104. The outside surface of the electrical connector 202 is shown in hexagonal form, matching the interior surfaces of the jaws of the compression device shown in FIG. 10. Other shapes are also contemplated.

Referring to FIG. 13, a cross-section view of the compressed electrical connector 202 is shown. The outer tube 320 surrounds and is compressed into the compression device 300 which surrounds and is compressed into the insert 500 which surrounds and is compressed into the core 602. Of course, in some examples, the insert 500 layer shown in FIG. 13 could be replaced by the base row 608 of wires, depending upon the embodiment of the electrical connector 202.

Referring to FIG. 14, one example of the insert 500 is shown. In this example, the insert 500 includes an exterior surface 1400 defining longitudinal grooves 1402 along an axial length of the insert 500. The insert 500 comprises a second composition material, for example, aluminum. Relating back to the clocking feature shown in FIG. 9, the clocking can be beneficial, as a compression device with jaws 1000 as shown in FIG. 10 can be more effective if it applies force at the high points along the exterior surface 1400 of the insert 500, and not the low points of the longitudinal grooves 1402.

In some examples, the annular cylinder (e.g., insert 500) comprises a helical arrangement of extruded material. In one particular example, the annular cylinder is composed of eleven separate strands of aluminum wound in a helix arrangement. In some examples, the annular cylinder can be of various shapes, designs, etc., not just helical. Some examples can include a mesh similar to metal woven fabric, or screens.

Presently, a method of making a compression connector assembly using an electrical connector will be discussed. The components described above can be used to form a compressed assembly. The method includes the step of inserting the compression device into the through hole of the outer tube. As described above, the two components can be joined through a threaded connection. An installer then continues the method by removing a length of a top wire row from an end of the associated electrical conductor to expose the core and the base row of wires at the end of the associated electrical conductor.

Then, the installer inserts the core and the base row of wires into the aperture of the compression device. After the core and the base row of wires have been inserted to the desired length within the aperture, the method then includes radially compressing a length of the outer tube in order to radially compress the outer tube, the compression device, the base row of wires, and the core. In this process, as noted above, the outer tube, the compression device, the base row of wires, and the core form a unified group such that the associated electrical conductor cannot be removed from the outer tube and the compression device.

In this compressed assembly, the compressed assembly is contiguous with a second portion of the base row of wires and a second portion of the core of the associated electrical conductor. For the purposes of this disclosure, the term contiguous is meant to include the concept of being continuous. In other words, the compressed assembly, by including the base row of wires in the compression process, the compressed assembly is physically connected through the base row of wires to the associated electrical conductor; there is no separation between the two. In this way, the compressed assembly and the electrical conductor are monolithic, or one piece.

It is to be understood that the described apparatus and method simplifies the design of such dead-end connectors or electrical connectors by only using a steel outer compression sleeve and the conductor itself and compressing them together. The core and base row of wires (e.g., aluminum wires) around the core are used in the compressing fitting. The installer will cut back all the layers on top of the base layer of aluminum to set a grip length. This length is then installed in the steel fitting. The steel fitting is then compressed at the first end reducing the ratio of steel and aluminum filler material between the core and compression fitting. The steel fitting is designed with an overflow chamber or aluminum expansion chamber for excess extruded aluminum to move into as the compression operation continues toward the end of the conductor. Compressing toward the open end of the core allows for the core to slightly shift, instead of binding, and this allows the aluminum strands to extrude at their own rate.

As a brief summary, the described apparatus and methods use the base, extruded layer of aluminum wire or strands formed in place by a conductor manufacturer or an interlocked, helically extruded bundle of trapezoidal wires as the filler between the core and steel compression. By using the extruded material already in place, the installer has the tightest fit around the core so that occurrences of uneven compressions are reduced or eliminated. Additionally, the shape of the strands and the configuration of individual strands keeps the compression uniform to allow the strands to extrude as necessary. Because the strands are attached to the conductor, this ensures that the filler is seated properly on the core and does not shift during installation. Because the strands are extruded, there is no burr or machine edge to damage or cut the core during compression. Additionally, compressing away from the conductor, the stress on the free end of the core is reduced. This direction of compression also eliminates an issue called “birdcaging” when the aluminum extrudes into other sections of aluminum.

In a further description of the compressed assembly, the compressed assembly includes a first portion of a base row of wires and a first portion of a core of an associated electrical conductor received within an aperture defined within a first end of a compression device that extends along a compression device axis between the first end and a second end. The first portion of the base row of wires is compressed and is contiguous with a second portion of the base row of wires that is not compressed, and the first portion of the core is contiguous with a second portion of the core.
