Description
Technical field
The utility model relates to a kind of line hardware, particularly a kind of strain clamp.
Background technology
Strain clamp is the termination for fixing cord, and bears the gold utensil of wire tension, is mainly used in fixing cord and lightning rod on the insulator string of strain insulator, corner, terminal shaft tower.Strain clamp has two classes, and first kind strain clamp only bears whole pulling force of wire, lightning conducter and bracing wire, but does not make conductor; Equations of The Second Kind strain clamp is except bearing the whole pulling force of wire and lightning conducter, again as conductor.Bolt-type strain clamp belongs to the first kind and only bears the wire clamp of tension force, wire is pressed in the groove of wire clip body by U-bolt, pressing plate, thrust produce frictional force make wire clamp to bear the pulling force of wire, and wire clamp can bear the pulling force of wire can not be lower than 90% of the specified stretching resistance of wire.Therefore, in the situation that ensureing not increase volume size, how to improve the ability of its anti-wire tension, most important for the use of bolt-type strain clamp.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of strain clamp, can improve the ability of its opposing wire tension.
Strain clamp of the present utility model, comprise clamp, pressing plate and U-bolt, described clamp comprises compressed part, turning part and edge sub-connection portion, described compressed part and turning part entirety are L-type, clamp be provided with connect from clamping section to guide part for placing the groove of wire, described pressing plate is positioned at top, clamping section, be connected pressing plate is pressed on wire with nut through behind clamping section by U-bolt, described insulator connecting portion is oppositely extended to form by the recess sidewall of turning part, insulator connecting portion is provided with the hole for being connected with insulator, described insulator connecting portion and turning part are hinged, on insulator connecting portion, be fixed with briquetting, described briquetting stretches in the groove of turning part, insulator laterally when strain insulator connecting portion briquetting together rotate compression wire with insulator.
Further, described briquetting and wire contact surface are provided with graininess projection.
Further, described pressing plate bottom is provided with two arc convex with the contact-making surface of wire, and the below of described compressed part respective arcuate projections is provided with two arc grooves.
The beneficial effects of the utility model: strain clamp of the present utility model, comprise clamp, pressing plate and U-bolt, described clamp comprises compressed part, turning part and edge sub-connection portion, described compressed part and turning part entirety are L-type, clamp be provided with connect from clamping section to guide part for placing the groove of wire, described pressing plate is positioned at top, clamping section, be connected pressing plate is pressed on wire with nut through behind clamping section by U-bolt, described insulator connecting portion is oppositely extended to form by the recess sidewall of turning part, insulator connecting portion is provided with the hole for being connected with insulator, described insulator connecting portion and turning part are hinged, on insulator connecting portion, be fixed with briquetting, described briquetting stretches in the groove of turning part, insulator laterally when strain insulator connecting portion briquetting together rotate compression wire with insulator.Wire clamp in use wire is not only clamped in clamping section, and in the time that wire clamp bears insulator tension, wire is compacted in turning part simultaneously, and wire is difficult for slippage.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is that master of the present utility model looks schematic diagram;
Fig. 2 is that schematic diagram is looked on the right side of the present utility model.
