Abstract
A strain clamp provided with a protective cover comprises a base provided with an open wedge-shaped cavity. Wedge cores which are matched for use in pairs are arranged in the wedge-shaped cavity, a base is connected with a pull rod, the surface of the base is movably connected with the protective cover, and the protective cover totally buckles and seals the opening side of the wedge-shaped cavity to form a closed strengthening structure of the base. The protective cover totally buckles and seals the opening side of the wedge-shaped cavity, and the base is closed, so that a stress structure is strengthened and reasonable, and stress is not prone to partial concentration. Even if the wall thickness of the base is thin or the strain clamp is made of non-metal materials, work stress performance of the strain clamp is not reduced. Therefore, the weight of a product is reduced, cost is reduced, and excessive concentration of dust and moisture in the wedge-shaped cavity is avoided.
Description
Technical field
The utility model relates to a kind of electric armour clamp, particularly the strain clamp of fixed insulation lead.
Background technology
The electric insulation lead generally all needs to use strain clamp when fixing, tensioning, all is to utilize paired wedge core to clamp the electric insulation lead earlier usually, puts into the wedge cavities fixed tensioning of strain clamp again.The wedge cavities of existing strain clamp all is uncovered open, be convenient to unwrapping wire and manufacturing, but uncovered open wedge cavities causes the force structure of pedestal unreasonable, local stress is concentrated easily, and in order to guarantee the work stress performance of strain clamp, pedestal generally can only be selected the manufacturing of working strength preferred metal material, the weight of product is big, the cost height also produces magnetic hysteresis loss easily when transmission of electricity, increased the transmission of electricity waste.And concentrate dust moisture in the uncovered open wedge cavities easily, accelerated the corrosion of pedestal.
Summary of the invention
At the deficiencies in the prior art, the utility model provides a kind of force structure reasonably to be with the over cap strain clamp.
The utility model comprises the pedestal that is provided with uncovered open wedge cavities; the wedge core that is used in pairs places wedge cavities; be connected with pull bar on the pedestal; on base-plates surface, also be connected with over cap; this over cap fastens the uncovered open sides of sealing wedge cavities fully, forms the closed structure that strengthens of pedestal.
The utility model utilizes over cap to fasten the uncovered open sides of sealing wedge cavities fully; the pedestal closure; force structure strengthens rationally; stress is difficult for concentration of local; even the wall thickness of pedestal is thinner even use the nonmetallic materials manufacturing also can not reduce the work stress performance of strain clamp; can make the weight saving of product, cost reduces, and avoids the mistake of dust moisture in the wedge cavities to focus mostly on.
Further specify the utility model below in conjunction with drawings and Examples.

Embodiment
Extremely shown in Figure 5 as Fig. 1; pedestal 1 is provided with uncovered open wedge cavities 2; the wedge core 3 that is used in pairs places wedge cavities 2; be connected with pull bar 4 on the pedestal 1; on pedestal 1 surface, also be connected with over cap 5; this over cap 5 fastens the uncovered open sides of sealing wedge cavities 2 fully, forms the closed structure that strengthens of pedestal.Present embodiment is provided with flange 6 in pedestal 1 both sides at the uncovered open place of wedge cavities 2, the two inboard corresponding grooves 7 that are provided with of over cap 5, and the flange 6 of pedestal 1 places the groove 7 of over cap 5 to be connected, and the easy accessibility of over cap 5 is connected firmly like this.
In fact, be equipped with many reinforcements 8 on the outer surface of pedestal 1 and over cap 5, further strengthen structural reliability.Pedestal 1 and over cap 5 all can adopt the nonmetallic materials manufacturing, and be in light weight, easily manufactured as compound resin etc., and cost reduces, the magnetic hysteresis loss of not transmitting electricity, and energy-conserving and environment-protective more, and also integrally-built work stress performance is reliable.
When installing and using; as shown in Figure 6; the wedge cavities 2 of pedestal 1 is lived and is put in wedge core 3 clampings that insulated conductor 9 usefulness are paired, utilizes the groove 7 of over cap 5 and the flange 6 of pedestal 1 to cooperatively interact then, and over cap 5 is connected pedestal 1 surface and fastens the uncovered open sides that seals wedge cavities 2 fully.Behind the tension insulated conductor 9, the chucking power of 3 pairs of leads of wedge core can be increasing trend under deadweight and tensile force effect, and clamping is very reliable, the reasonable integral structure of strain clamp, and the work stress performance is good.4 on pull bar is for being connected with other gold utensil whole wire clamp to be fixed on electric pole.
