Abstract
The utility model discloses a low-voltage composite insulator which is used at two ends of a low-voltage service line, and comprises an upper hardware fitting, a core rod and a lower hardware fitting connected in sequence, a disc-shaped umbrella skirt is coated on the outer surface of the core rod, and the low-voltage composite insulator is characterized in that two metal pressing plates and four screws for fixing the pressing plates are matched on the upper hardware fitting of the insulator, the middle of the pressing plate is semicircular, and a semicircular wire slot is arranged at the part corresponding to the semicircular part of the pressing plate. The end part of the wire is placed in the semicircular wire slot, the pressing plates are pressed on the wire, and the screws firmly fix the pressing plates and the wire on the insulator. The low-voltage insulator can be used as a linear insulator and also a tension insulator.
Description
Technical field
The utility model belongs to the low-voltage distribution technical field, is specifically related to a kind of low pressure composite insulator.
Background technology
Lay the low pressure composite insulator that use on the low-voltage overhead line road along building surface, form by the insulating coating that gold utensil, insulation mandrel and composite material constitute.It is compared with conventional insulators (Tea Service), has the separate ability of aid identification lead, and creepage distance can satisfy primary cable lightning protection demand greater than 100mm, adopts the screw fashion fixing cord, and solid degree and workman's level of skill is irrelevant.But the last gold utensil of this insulator is made with cast aluminium, and has only a slice to grip the aluminum pressing plate of lead, and is less to the grip of lead, can not use as strain insulator; The diameter of its plug is also little, can not bear the pulling force of lead, can only be used as the straight line insulator.
Summary of the invention
The purpose of the utility model is to provide a kind of low tension insulator to be used for overcoming disadvantages of background technology.This insulator not only can be used as the straight line insulator, can also be used as strain insulator.
For achieving the above object; The technical scheme that the utility model adopts is: low tension insulator comprises gold utensil, following gold utensil, plug and full skirt; It is characterized in that being furnished with on the last gold utensil of insulator four screws of two metal platen and fixation clip; The middle part semicircular in shape of pressing plate, corresponding with the pressing plate semi-circular portion is a semicircle wire casing.Semicircle wire casing is put in the end of lead, and pressing plate is pressed on the lead, and screw firmly is fixed on pressing plate and lead on the insulator.This low tension insulator can be done strain insulator and use.
Last gold utensil is made with antiseptic steel, and symmetry has four screw holes, is carved with screw thread in the hole, and top is flat tetragonal body, and corner angle have partly carried out chamfered.
It is cylindric that plug is, and diameter increases by 20～30% than the plug of conventional insulator.
Pressing plate is made with antiseptic steel, upwards slightly arches upward in the middle part, and two ends are circular-arc.
The beneficial effect of the utility model is:
1. go up four screws being furnished with two metal platen and fixation clip on the gold utensil, improved the curable grip of insulator to lead greatly, lead can not break away from from insulator.
2. go up gold utensil and pressing plate and all adopt steel to make, the mechanical strength of insulator is greater than conventional low pressure composite insulator.
3. diameter of mandrel increases by 20～30% than the plug of conventional low pressure composite insulator, and the bending resistance of insulator is greater than conventional low pressure composite insulator.
Since mechanical strength and bending resistance all greater than conventional low pressure composite insulator, the utility model not only can be used as the straight line insulator, can also be used as strain insulator.

In the accompanying drawing: 1, housing pin, 2, pressing plate, 3, go up gold utensil, 4, full skirt, 5, gold utensil down, 6, flat shim, 7, spring washer, 8, nut, 9, plug, 10, wire casing, 11, screw hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in 2, adopt steel to make pressing plate 2, upwards slightly arch upward in the middle part, and two ends are circular-arc, and slotted hole is opened at two ends.
Like Fig. 1, shown in 2, housing pin 1 usefulness steel are made, and cylindric, appearance is carved with screw thread.
Like Fig. 2, shown in 3, make upward gold utensil 3 with steel, last gold utensil 3 has semicircle wire casing 10; The edge-smoothing of wire casing does not have corner angle, and symmetry has four screw holes 11, is carved with screw thread in the hole; Last gold utensil 3 tops are flat tetragonal bodies, and corner angle have partly carried out chamfered.
Like Fig. 1, shown in 3, following gold utensil 5 usefulness steel are made, the bottom be cylindric, iron pin that screw thread is carved with on the surface, be furnished with flat shim 6, spring washer 7, nut 8 on the iron pin.
As shown in Figure 3, it is cylindric that plug is, and processed by high-strength insulating material.
As shown in Figure 1, last gold utensil 3 is descending at upper and lower gold utensil 5, with gold utensil about the two ends embedding of plug 9, will go up gold utensil 3, plug 9, play gold utensil 5 to be crimped on together with mechanical force.
As shown in Figure 1, with high temperature silicon rubber casting full skirt 4, will go up gold utensil during the casting full skirt, play the part of gold utensil and expose their external plugs 9 to seal.
During fixing cord, earlier lead is put into the wire casing 10 of gold utensil 3, after pressing plate 2 is placed on the lead, again housing pin 1 is inserted in the screw hole 11, use the fastening housing pin 11 of spanner at last, this moment, lead 15 was firmly clamped by pressing plate 2 and wire casing 10.The iron pin of following gold utensil 5 is used for the utility model is fixed on the building.
