The electrical connector includes a body having a tubular shape, a centerline extending along a longitudinal direction of the body, and an opening extending along the centerline from an outer surface of the body to the center cavity. The body includes a center cavity configured to receive and encase the core. The centerline defines a first portion and a second portion such that the first portion includes a bore hole configured to receive a bolt and the second portion includes a tap hole with a tapered threaded portion configured to receive a screw portion of the bolt. The tap hole is aligned with the bore hole so that the bolt may connect the bore hole and the tap hole to close the opening. ## Claims ### Claim 1 An electrical connector assembly configured to control a compression force applied to a core, the electrical connector assembly comprising the core including at least one selected from a group consisting of a carbon composite and a glass fiber, and an electrical connector including: a body having a tubular shape and including a center cavity configured to receive and encase the core; a centerline extending along a longitudinal direction of the body, the centerline defining a first portion and a second portion; and an opening extending along the centerline from an outer surface of the body to the center cavity, wherein the first portion includes a bore hole configured to receive a bolt, wherein the second portion includes a tap hole with a tapered threaded portion configured to receive a screw portion of the bolt, wherein the tap hole is aligned with the bore hole, and wherein the bolt connects the bore hole and the tap hole to close the opening. ### Claim 2 (depends on 1) The electrical connector assembly according to claim 1, wherein the bore hole and the tap hole are aligned with the opening such that there is no interference of the bore hole and the tap hole with the center cavity. ### Claim 3 (depends on 1) The electrical connector assembly according to claim 1, wherein the first portion further includes a plurality of bore holes and the second portion further includes a plurality of tap holes, the plurality of bore holes and the plurality of tap holes being positioned at multiple locations along the opening such that there is no interference of the plurality of bore holes and the plurality of tap holes with the center cavity. ### Claim 4 (depends on 3) The electrical connector assembly according to claim 3, wherein each of the plurality of tap holes is aligned to a corresponding bore hole. ### Claim 5 (depends on 1) The electrical connector assembly according to claim 1, further comprising another opening extending along the centerline from the outer surface of the body to the center cavity, the another opening being positioned directly opposite the opening such that the first portion fully disengages from the second portion. ### Claim 6 (depends on 5) The electrical connector assembly according to claim 5, further comprising another bore hole and another tap hole aligned with the another opening such that there is no interference of the another bore hole and the another tap hole with the center cavity. ### Claim 7 (depends on 6) The electrical connector assembly according to claim 6, wherein the first portion further includes a plurality of another bore holes and the second portion further includes a plurality of another tap holes, the plurality of another bore holes and the plurality of another tap holes being positioned at multiple locations along the another opening such that there is no interference of the plurality of another bore holes and the plurality of another tap holes with the center cavity. ### Claim 8 (depends on 7) The electrical connector assembly according to claim 7, wherein each of the plurality of another tap holes is aligned to a corresponding another bore hole. ### Claim 9 (depends on 1) The electrical connector assembly according to claim 1, wherein a circumference of the center cavity is smaller than an outer circumference of the core by a compression factor. ### Claim 10 (depends on 9) The electrical connector assembly according to claim 9, wherein the circumference of the center cavity applies a radial compression force on the outer circumference of the core via the bolt. ### Claim 11 (depends on 1) The electrical connector assembly according to claim 1, wherein the electrical connector is positioned within a conductor wire. ### Claim 12 (depends on 11) The electrical connector assembly according to claim 11, wherein the conductor wire includes three sets of wire strands wound around the core. ### Claim 13 (depends on 12) The electrical connector assembly according to claim 12, wherein the three sets of wire strands wound around the core include aluminum. ### Claim 14 A method of bolting an electrical connector to control a compression force applied to a core, the method comprising: defining a centerline extending along a longitudinal direction of a body, the centerline identifying a first portion and a second portion; boring a bore hole in the first portion to below the centerline; tapping a tapered tap hole in the second portion to align with the bore hole; cutting an opening extending along the centerline from an outer surface of the body to a center cavity configured to receive the core; positioning the core in the center cavity, the core including at least one selected from a group consisting of a carbon composite and a glass fiber; and bolting the bore hole to the tap hole via a bolt to close the opening. ### Claim 15 (depends on 14) The method according to claim 14, wherein boring the bore hole includes positioning the bore hole to align with the opening such that there is no interference of the bore hole with the central cavity. ### Claim 16 (depends on 14) The method according to claim 14, further comprising: boring another bore hole in the first portion to below the centerline; tapping another tap hole in the second portion to align with the another bore hole; cutting another opening extending along the centerline from the outer surface of the body to the center cavity, the another opening being positioned directly opposite the opening such that the first portion fully disengages from the second portion; and bolting the another bore hole to the another tap hole via another bolt to close the another opening, wherein the another bore hole is aligned with the another opening such that there is no interference of the another bore hole with the center cavity. ### Claim 17 (depends on 14) The method according to claim 14, further comprising winding a conductor wire around the body. ### Claim 18 (depends on 17) The electrical connector assembly according to claim 17, wherein the conductor wire includes three sets of wire strands wound around the core. ### Claim 19 An electrical connector assembly configured to control a compression force applied to a core, the electrical connector assembly comprising an electrical connector including: a body having a tubular shape and including a center cavity configured to receive and encase the core; a centerline extending along a longitudinal direction of the body, the centerline defining a first portion and a second portion; and an opening extending along the centerline from an outer surface of the body to the center cavity, wherein the first portion includes a bore hole configured to receive a bolt, wherein the second portion includes a tap hole with a tapered threaded portion configured to receive a screw portion of the bolt, wherein the tap hole is aligned with the bore hole, and wherein the bolt connects the bore hole and the tap hole to close the opening, and a conductor wire wound around the electrical connector. ### Claim 20 (depends on 19) The electrical connector assembly according to claim 19, wherein the electrical connector assembly includes the core, wherein the core includes at least one selected from a group consisting of a carbon composite and a glass fiber.
