Abstract
The utility model relates to a tension wire clamp for insulated conducting wires. The utility model comprises screw holes and a pull rod seat, wherein, the screw holes are arranged on a shell body. The utility model is characterized in that vertical ribs and horizontal ribs are arranged at the outer side of the shell body in an equispaced manner; the vertical ribs and the horizontal ribs form a wedge shape; the wedge-shaped inner cavity of the shell body is assembled with a wedge block core the outer side of which forms a wedge shape; convex points are arranged on the inner arc face of the wedge block core in a dense and equispaced manner. Conducting wires which are arranged in the wedge block core are synchronized with the wedge block core, and the conducting wires and the shell body slide correspondingly, and thereby, fastening is completed. The utility model belongs to the electric power fitting, being mainly applied to fastening for conducting wires in intermediate voltage and low voltage power networks.
Description
The utility model relates to a kind of strain clamp, especially a kind of insulated conductor strain clamp, and it belongs to electric armour clamp, can be widely used in the fastening of various insulated conductors in the mesolow electric power system in industry, rural area.
At present, existing strain clamp, outer cover intensity is low, pulling force, grip are little, getting tight wire sheath on the fastening bolt easily breaks, pine then makes lead strain slightly, and expanded with heat and contract with cold by the influence of the weather temperature difference, shell to cause lead loosening, when the lead of the mesolow electrical network in city, rural area changed insulated conductor into by bare wire especially at present, existing strain clamp more can't be used.
The purpose of this utility model is to provide a kind of insulated conductor strain clamp, has rational in infrastructurely, and pulling force, grip greatly, are not subjected to temperature difference influence, advantage such as easy to operate, are suitable for the fastening of mesolow line insulation lead.
The utility model above-mentioned purpose realizes by following technological means:
A kind of insulated conductor strain clamp.Comprise the screw and the draw-bar seat that are arranged on the housing, it is characterized in that the inner chamber of said housing is a wedge cavities, the contour structures voussoir core identical with the wedge cavities structure is housed in the cavity, wedge shape core center is provided with wire through-hole.Above-mentioned housing is that preferred design becomes two bodies symmetry assembly assembly structure with the voussoir core, and housing is provided with the bolt screw.Said voussoir core is preferably selected for use and is moulded syntheticly firmly, and wire through-hole is designed to circular port, is evenly equipped with intensive salient point on the inner surface, increases the frictional force between wire through-hole and the lead.The uniform in length and breadth reinforcement of hull outside is used to increase casing rigidity.
When using this strain clamp, lead is put into the voussoir in-core, again the voussoir core is put into the housing wedge cavities, then with bolt by screw with the fastening one that is assembled into of housing.When the pull bar that penetrates draw-bar seat under external force, when the motion of the big extreme direction of wedge shape, the voussoir core is carried the relative housing of lead secretly and is made reverse slide.According to wedge principle, it is sliding more tight more that the voussoir core is carried lead secretly, and the salient point on the circle has increased friction in the voussoir core wire through-hole.When having reached suitable pulling force, grip, stop.The voussoir core is made with synthetic plastic, and is harmless to lead, and is subjected to temperature difference influence minimum.
The insulated conductor strain clamp that the utility model provides, have volume little, rational in infrastructure, be not subjected to temperature difference influence, advantage such as applied widely, pulling force is big, and grippable effect is good.
Introduce the utility model specific embodiment in detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural front view.
Fig. 2 is the utility model structure side view.
Fig. 3 is that the A of Fig. 1 is to view.
In the present embodiment, housing 1 is divided into two body symmetrical structures, and housing is provided with four screws 2 and two draw-bar seats 4, each draw-bar seat 4 is equipped with tie rod hole 8, housing 1 outside is shaped as wedge shape, and there is uniform in length and breadth muscle 5 in the outside, and 6 are equipped with the voussoir core of making of ABS resin 3 in its wedge cavities.Be evenly equipped with intensive salient point 7 on the arc face in its wire through-hole 9.
