Abstract
A cable clamp provided with a tension-resistant cable clamp with a protection cover comprises a base which has an opening type wedge-shaped cavity, wedge cores which are used in pair in a matched mode are arranged inside the wedge-shaped cavity, the base is connected with a pull rod, and the surface of the base is further movably connected with the protection cover which is completely buckled on the opening side of the sealed wedge-shaped cavity to form a base close reinforcing structure. According to the fact that the protection cover is completely buckled on the opening side of the sealed wedge-shaped cavity, the base is closed, the stress structure is reinforced reasonably, and stress local concentration does not occur easily. Even if the wall of the base is thin or the base is made of non-metal material, work stress performance of the tension-resistant cable clamp cannot be reduced, weight of products can be lightened, cost is reduced, and too much concentration of dust and water in the wedge-shaped cavity is avoided.
Description
Technical field: the present invention relates to a kind of electric armour clamp, particularly the strain clamp of fixed insulation wire.
Background technology: the electric insulation wire generally all needs to use strain clamp when fixing, tensioning, is all first to utilize paired wedge core to clamp the electric insulation wire usually, then puts into the wedge cavities fixed tensioning of strain clamp.The wedge cavities of existing strain clamp is all uncovered open, be convenient to unwrapping wire and manufacturing, but uncovered open wedge cavities causes the force structure of pedestal unreasonable, local stress is easily concentrated, and in order to guarantee the work stress performance of strain clamp, pedestal generally can only the metal material manufacturing preferably of choice for use intensity, the weight of product is large, cost is high, also easily produces magnetic hysteresis loss when transmission of electricity, has increased the transmission of electricity waste.And easily concentrate dust moisture in uncovered open wedge cavities, accelerated the corrosion of pedestal.
Summary of the invention: for the deficiencies in the prior art, the invention provides a kind of force structure and reasonably be with the over cap strain clamp.
The present invention includes the pedestal that is provided with uncovered open wedge cavities; the wedge core that is used in conjunction with in pairs is placed in wedge cavities, is connected with pull bar on pedestal, also is connected with over cap on base-plates surface; this over cap fastens the uncovered open sides of sealing wedge cavities fully, forms the closed structure that strengthens of pedestal.
The present invention utilizes over cap to fasten the uncovered open sides of sealing wedge cavities fully; pedestal is closed; force structure strengthens rationally; stress is difficult for concentration of local; even the thinner work stress performance that even uses the nonmetallic materials manufacturing also can not reduce strain clamp of the wall thickness of pedestal; can make the weight saving of product, cost avoids the mistake of dust moisture in wedge cavities to focus mostly on.
Further illustrate the present invention below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the front view of embodiment.
Fig. 2 is the stereogram of Fig. 1.
Fig. 3 is the stereogram of pedestal.
Fig. 4 is the stereogram of over cap.
Fig. 5 is the A-A profile of Fig. 1.
Fig. 6 is the working state schematic representation of Fig. 2.
Embodiment: as extremely shown in Figure 5 in Fig. 1; pedestal 1 is provided with uncovered open wedge cavities 2; the wedge core 3 that is used in conjunction with in pairs is placed in wedge cavities 2; be connected with pull bar 4 on pedestal 1; also be connected with over cap 5 on pedestal 1 surface; this over cap 5 fastens the uncovered open sides of sealing wedge cavities 2 fully, forms the closed structure that strengthens of pedestal.The 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 groove 7 that the flange 6 of pedestal 1 is placed in over cap 5 is connected, and the easy accessibility of over cap 5, be 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 as lightweight, easily manufactured in compound resin etc., cost, and the magnetic hysteresis loss of not transmitting electricity, 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 use are paired, then utilizes the groove 7 of over cap 5 and the flange 6 of pedestal 1 to cooperatively interact, and over cap 5 is connected to pedestal 1 surface and fastens the uncovered open sides that seals wedge cavities 2 fully.After tension insulated conductor 9, the chucking power of 3 pairs of wires 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, pull bar be for be connected gold utensil and connect whole wire clamp is fixed on electric pole.
