The utility model content
At the problem that prior art exists, the purpose of this utility model provides a kind of fixedly conductor spacer of reliability that can improve between circuit and the conductor spacer.
For achieving the above object, a kind of conductor spacer of the utility model, comprise framework and wire clamp, described wire clamp is arranged on the described framework, wire clamp is made of preformed armor rods and chuck, and described chuck is provided with an open groove that is used for ccontaining power transmission line, and described preformed armor rods is crossed on the power transmission line that described chuck is wrapped in the chuck both sides, and when crossing over chuck, it is twined in the lump, chuck and the power transmission line that crouches in its groove are interfixed.
Further, described chuck is provided with the chuck of being made by elastomeric material and overlaps this chuck cover and be sleeved on the chuck.
Further, described chuck is provided with the position limiting structure that is complementary with described preformed armor rods.
Further, described position limiting structure is the stopper slot that described chuck two sides are provided with.
Further, described stopper slot is by convexing to form that described chuck two sides are provided with.
Further, described stopper slot is to cut out a formation on the described chuck side.
Further, described position limiting structure is the through hole that is provided with on the described chuck, and described preformed armor rods passes this through hole when crossing over chuck.
Further, described preformed armor rods two ends are gradually to the close taper in power transmission line surface of its winding.
The utility model is fixed together wire clamp and power transmission line by preformed armor rods and open chuck groove, the change of the fineness degree of power transmission line can not influence the fixed effect of wire clamp and power transmission line, improved the fixedly reliability of wire clamp and power transmission line, and can further improve circuit running quality and life-span.
