The clamper main body of wire clamp adopts the preformed armor rods structure, has effectively disperseed stress, has reduced the strain in wire clamp exit, and wire has been protected in the fatigue failure that has alleviated wire well; The middle body region of conductor spacer adopts the cross yoke plate to make the yoke plate intensity enhancing, after wire clamp is fastening by fastening bolt and cross yoke plate, formed a complete general frame, make quality, moment of inertia, the stiffness distribution of conductor spacer best, when four wire icings are inhomogeneous, since the general frame mass concentration of conductor spacer in the center and support arm longer, conductor spacer reverses the oneself to restore balance.Cross pin and cross pin are installed in each wire clamp to be pressed in wire clamp by rubber column and to have consisted of hinge means between cross yoke plate and the corresponding wire clamp, formed the core component of the hinge means at conductor spacer middle part by cross pin, this structure can adapt to the angle displacement of wire clamp well, this angle displacement of wire clamp tends to cause the distortion of rubber column, the ability of this distortion can make the hinge place have good elasticity and cushioning ability, because rubber column mainly bears extruding force, so the anti-fatigue performance of this structure is more outstanding.
The line with rubber pad can be securely fixed in wire in the stand in each wire clamp stand, and prevents that relative motion owing to wire from causing the damage of wire.Preformed armor rods on the stand will clamp wire and stand around the wire clamp stand, wear the pin form of holding with a firm grip with common chuck hinge type structure and compare, and the extruding force that this structure is born the contact point of wire and wire clamp stand is much smaller.It is simple, reliable and be difficult for makeing mistakes that above-mentioned conductor spacer and wire connecting mode are installed.
Also be provided with the ear section that adopts the curve transition structure on stand, preformed armor rods is wrapped in ear section.The place of the easiest generation corona is the wire clamp chuck end of conductor spacer, has adopted the curve transition structure at the ear position of chuck external drum dress preformed armor rods, and structure is attractive in appearance, and preferably effect has been played in the impact that reduces corona and radio interference.Preformed armor rods is helical form, and be elastomer, the helical form of preformed armor rods is conducive to preformed armor rods and around the wire clamp stand wire and stand is clamped, the elasticity of preformed armor rods can compensate owing to creep causes wire any variation diametrically, play the effect of certain absorption conductor vibration energy, simple in structure, easy for installation.
Above-mentioned rubber column is by also making with No. 1 material of glue, and rubber blanket is by also making with No. 2 materials of glue.Rubber column, rubber blanket are the employed damping element of conductor spacer, institute adopts to such an extent that also all belong to the high polymer viscoelastic material with glue 1, No. 2 materials, with high polymer as the absorbing material, have good Weather-resistant, ozone resistance, anti-vibration fatigability and volume resistance, and the mechanical performance that tool is good at low temperatures, enough elasticity.
The utility model is simple in structure, easy for installation; strengthened the steadiness that conductor spacer connects with wire, adapted to well wire clamp angle displacement, reduced the extruding force between wire clamp and the wire and reduced the strain in wire clamp exit so that anti-fatigue performance has been protected wire well, well.
