DeFrance - Web page: https://patentgrep.com/patent/US10374407B2 ## CPC - H02G 7/12: Devices for maintaining distance between parallel conductors, e.g. spacer - H02G 7/08: Members clamped to the supporting wire or to the line or cable - H02G: INSTALLATION OF ELECTRIC CABLES OR LINES, OR OF COMBINED OPTICAL AND ELECTRIC CABLES OR LINES ## Abstract Conductor spacer assemblies are disclosed that can be easily and rapidly clamped to parallel electrical conductors suspended between supports, and that can be easily and rapidly secured together with an automatically actuated fastener assembly. The conductor spacer assembly includes an upper spacer body that is coupled to a lower spacer body and an automatically actuated fastener assembly that facilitates quick and safe installation of the conductor spacer assemblies. ## Claims ### Claim 1 A spacer assembly used to separate parallel overhead electrical conductors comprising: an upper spacer body comprising: a first clamp half at a first end of the upper spacer body and a first bushing half within the first clamp half; a second clamp half at a second end of the upper spacer body and a second bushing half within the second clamp half; and a bore extending through the upper spacer body; a lower spacer body comprising: a third clamp half at a first end of the lower spacer body and a third bushing half within the third clamp half; a fourth clamp half at a second end of the lower spacer body and a fourth bushing half within the fourth clamp half; and a tapered bore extending through the lower spacer body; wherein the first bushing half and the third bushing half form a first space to receive a first conductor when the upper spacer body and the lower spacer body are moved to a clamping position, and wherein the second bushing half and the fourth bushing half form a second space to receive a second conductor when the upper spacer body and the lower spacer body are moved to the clamping position; a fastener assembly having a fastener, a biasing member and a wedge pin, wherein the fastener fits within the bore and includes a cavity to receive the biasing member and at least a portion of the wedge pin such that the biasing member and the at least a portion of the wedge pin are movable within the cavity, the biasing member and the at least a portion of the wedge pin being maintained within the cavity by a shoulder at a distal end of the fastener; and wherein as the bore is aligned with the tapered bore the biasing member causes the wedge pin to automatically move into the tapered bore. ### Claim 2 (depends on 1) The spacer assembly according to claim 1, wherein the fastener comprises a threaded bolt. ### Claim 3 (depends on 1) The spacer assembly according to claim 1, wherein the biasing member comprises a compression spring. ### Claim 4 (depends on 1) The spacer assembly according to claim 1, wherein the wedge pin comprises a shaft, a tapered tip at a distal end of the shaft and a barrel at a proximal end of the shaft. ### Claim 5 (depends on 4) The spacer assembly according to claim 4, wherein the shoulder engages the barrel to maintain the biasing member and the at least a portion of the wedge pin within the cavity. ### Claim 6 (depends on 4) The spacer assembly according to claim 4, wherein the barrel has a diameter that is greater than a diameter of the shaft. ### Claim 7 A spacer assembly used to separate parallel overhead electrical conductors comprising: an upper spacer body coupled to a lower spacer body such that the upper spacer body is longitudinally movable relative to the lower spacer body between an open position and a clamping position, wherein when in the clamping position a first end of the upper spacer body and a first end of the lower spacer body form a first space to receive a first conductor and a second end of the upper spacer body and a second end of the lower spacer body form a second space to receive a second conductor; and a fastener assembly having a fastener, a biasing member and a wedge pin, wherein the fastener fits within a bore in the upper spacer body and includes a cavity to receive the biasing member and at least a portion of the wedge pin such that the biasing member and the at least a portion of the wedge pin are movable within the cavity, the biasing member and the at least a portion of the wedge pin being maintained within the cavity by a shoulder at a distal end of the fastener, and wherein as the bore is aligned with a tapered bore in the lower spacer body, the biasing member causes the wedge pin to automatically move into the tapered bore. ### Claim 8 (depends on 7) The spacer assembly according to claim 7, wherein the first space is formed by a first clamp half at the first end of the upper spacer body and a first bushing half within the first clamp half, and a second clamp half at a first end of the lower spacer body, and a second bushing half within the second clamp half. ### Claim 9 (depends on 7) The spacer assembly according to claim 7, wherein the second space is formed by a third clamp half at a second end of the upper spacer body and a third bushing half within the third clamp half, and a fourth clamp half at a second end of the lower spacer body and a fourth bushing half within the fourth clamp half. ### Claim 10 (depends on 7) The spacer assembly according to claim 7, wherein the fastener comprises a threaded bolt. ### Claim 11 (depends on 7) The spacer assembly according to claim 7, wherein the biasing member comprises a compression spring. ### Claim 12 (depends on 7) The spacer assembly according to claim 7, wherein the wedge pin comprises a shaft, a tapered tip at a distal end of the shaft and a barrel at a proximal end of the shaft. ### Claim 13 (depends on 12) The spacer assembly according to claim 12, wherein the shoulder engages the barrel to maintain the biasing member and the at least a portion of the wedge pin within the cavity. ### Claim 14 (depends on 12) The spacer assembly according to claim 12, wherein the barrel has a diameter that is greater than a diameter of the shaft.
