Description of drawings

Fig. 1 is the half sectional view of the utility model.

Embodiment

To combine accompanying drawing that the utility model is described further below.

See also Fig. 1, the utility model modified model lightning protection pillar insulator has been shown among the figure, it comprises insulator body 1, goes up cap 2, lower flange 3, binding clip 5, insulating cover 6 and insulating sleeve 4.Insulator body 1 upper end glue cap 2, lower end mucilage binding lower flange 3 makes them become an organic whole, and wherein, last cap 2 is a umbrella-shaped structure, has adopted the integrated design that encircles with discharge, adopts the whole compacting of aluminium alloy to form.

Binding clip 5 comprises compressing member 51, be fixed in the left hold-down bolt (not drawing among the figure) at cap 2 tops and the right hold-down bolt 52 of spring is housed; One end of compressing member 51 is provided with through hole; The through hole that right hold-down bolt 51 passes compressing member 51 is connected with clamp nut; Compressing member 51 can horizontally rotate motion around right hold-down bolt 51, and the other end of compressing member 51 is provided with the U type and buckles, and left hold-down bolt passes this U type and buckles with clamp nut and be connected.

Insulating sleeve 4 is wrapped in the open upper end part of lower flange 3.

When installing at the scene, at first that insulator body 1 is rack-mount, and fix; Insulated conductor 7 is done local exposedization processing at compressing member 51 places, be placed on the recess of cap 2 to the exposed part of insulated conductor 7, rotatably compress part 51 left hold-down bolt is placed in its U type buckles; Through clamp nut that compressing member 51 is fixing; Make insulated conductor 7 be firmly fixed between compressing member 51 and the last cap 2, insulated conductor 7 installs like this, with insulating cover 6 from the supreme cap 2 of the main header casing of compressing member 51; Make insulated conductor 7 and insulator body 1 upper end be wrapped together, satisfy the requirement of the insulating of circuit.
