Abstract

A conductor clamp for pivoting support on the outer end of a power line insulator and including means for anchoring a conductor stringing assembly aligned with the clamp seating channel until the conductor has been seated in the clamp.

Claims

1. A conductor clamping unit adapted to be mounted on the outer end of a rigidly supported power line insulator, said clamping unit having an elongated horizontally-disposed main body formed lengthwise thereof with an upwardly opening conductor seating channel having a depth substantially greater than the radius of the conductor to be clamped therein, boss means projecting laterally from the opposite sides of the midportion of said main body having aligned wells in the outer ends thereof for pivotally securing said main body to the outer end of an insulator with said conductor seating channel facing upwardly and unobstructed to receive and seat a conductor in said channel, means carried by said main body outwardly of said conductor seating channel arranged to cooperate with juxtaposed portions of a conductor stringing unit to hold the latter firmly assembled there to with said conductor seating channel parallel to and positioned to receive a conductor from said stringing unit, conductor clamping jaw means extending across the mid portion of said conductor seating channel rigidly clampable thereacross by fastener means located adjacent the mid portion of said main body and functioning independently of stringing unit holding means.

2. A conductor clamping unit as defined in claim 1 characterized in that said clamping jaw means is of inverted J-shape having a stem portion slotted upwardly from the lower end thereof and sized to straddle said boss means, and said fastener means comprising a cap screw seated in a threaded bore formed in said boss means.

3. A conductor clamping unit for power line conductors and designed to serve as a support for a conductor stringing block prior to use to clamp a conductor therein, said clamping unit having an elongated main body of generally U-shape in cross section to provide a deep conductor seating channel therealong and opening tHrough the opposite ends thereof, said channel being substantially deeper throughout its length than the radius of the conductor to be seated therein to safeguard against the escape of a conductor being installed therein along curved sections of a power line, said channel opening upwardly and having lug means projecting from the lateral sides thereof sized and shaped to seat an accurately located conductor stringing block means above said main body and in position to release a strung conductor by gravity into said conductor seating channel, aligned boss means projecting laterally beyond the lower opposite sides of the mid portion of said main body having aligned wells in their outer ends adapted to seat trunnion supports of a conductor clamp support bracket embracing and confined to the underside of said clamping unit thereby leaving the area overlying the clamping unit unobstructed while stringing a conductor along the upper side of said seating channel, and clamping jaw means attached to said main body and adapted to be secured in place crosswise of the mid length of the upper portion of said conductor seating channel and including fastener means therefor securable to said main body independently of said lug means.

4. A conductor clamping unit as defined in claim 3 characterized in that at least one of said aligned boss means includes latch detent means adapted to interlock with assembly latch means of a conductor stringing block unit to hold the latter detachably in place on said main body while a conductor is being strung.

5. A conductor clamping unit as defined in claim 3 characterized in that said clamping jaw means includes a pair of lugs extending downwardly and straddling one of said boss means used to pivotally support said clamping unit.
