Abstract

A pole connector assembly for connecting adjacent pole sections in order to construct a pole. In some embodiments, these pole connector assemblies have two inserts connected together by a fastener. Each of the two inserts can be received within an open end of a respective pole section. The fastener can be received within an aperture in each of the inserts in order to connect the pole sections together. In some embodiments, each insert can have at least one projection that extends into the pole section within which the insert is received. The fastener can limit the at least one projection from being inwardly deflected in order to secure the insert within the corresponding pole section. In other embodiments, the fastener can have at least one deformable portion to allow the fastener to secure the insert within the corresponding pole section.

14. The pole connector assembly as claimed in claim 11, wherein the fastener further comprises a collar portion shaped to be received in at least a portion of the insert, the collar portion having an enlarged cross-sectional area relative to a remainder of the fastener.

15. The pole connector assembly as claimed in claim 11, wherein the at least one portion of the insert body includes at least ten projections.

16. The pole connector assembly as claimed in claim 11, wherein the at least one portion of the insert body includes at least four projections.

17. The pole connector assembly as claimed in claim 11, wherein the at least one portion of the insert body is shaped to engage an internal wall of the first pole section.

18. The pole connector assembly as claimed in claim 11, wherein the at least one inwardly-deflectable portion of the fastener body is shaped to engage an internal wall of the insert in at least one of a tongue-and-groove engagement and a snap-fit engagement.

19. The pole connector assembly as claimed in claim 11, further comprising a recess defined in an end of the at least one portion of the insert body, wherein the at least one inwardly-deflectable portion of the fastener body defines an enlarged end of the fastener shaped to be received within the recess in the insert body.

20. The pole connector assembly as claimed in claim 11, wherein the first and second ends of the fastener each have at least one inwardly-deflectable portion.

21. The pole connector assembly as claimed in claim 11, wherein the fastener is U-shaped.

22. A pole connector assembly for connection of two sections of a pole, the pole connector assembly comprising:
