Abstract
The utility model provides a strain clamp for an overhead insulated conductor provided with a steel core. The strain clamp comprises a body provided with a wedge-shaped cavity; a hanging plate is connected to the body; a through-groove is formed on the outer side wall of the wedge-shaped cavity of the body, so that a body structure with the cross section similar to a C shape is formed; wedge cores used in a pair are positioned in the wedge-shaped cavity and in loose fit with each other; and the overhead insulated conductor is arranged between the pair of wedge cores to be clamped and fixed. The clamp body of the strain clamp adopts the C-shaped structure, so that the concentrated stress produced when the wedge cores are in contact with the body can be reduced, the strength of the clamp body can be increased, the design is more reasonable, and materials used for production of the body can be saved at the same time; the wedge cores directly clamp the conductor, so that the clamping force is large, the conductor is prevented from slipping, the requirement for mounting the overhead insulated conductor provided with the steel core can be satisfied without the need of peeling off an insulating layer; by using the wedge cores, the clamp can be tighter when being pulled further, so that the line operation safety is well guaranteed, and the clamp can be conveniently mounted and easily operated and maintained; and furthermore, the wedge cores can be replaced according to the specification of the conductor, and the clamp can be detached and repeatedly used, thereby reducing the cost.
Description
Technical field: the utility model relates to a kind of electric armour clamp, particularly the strain clamp used of the suspended insulated guide wire of fixed band steel core.
Background technology: at present, along with the high speed development of electric line, more and more higher to the requirement of circuit transmission of electricity process safe, like this tensile strength of suspended insulated guide wire is had higher requirement, therefore the insulation aluminium stranded conductor with steel core has just arisen at the historic moment, and can carry very high intensity.But, still do not have on the market now and be specially adapted for the suspended insulated guide wire of steel core wedge type strain clamp, if using traditional insulation gold utensil that lead is carried out tensioning fixes, the insulating barrier that then needs to peel off lead could be installed, and greatly reduces the insulation level of circuit, influences the fail safe of circuit operation, and construction is complicated, operation requires high, and production efficiency is low, and grip strength is not high yet.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of clamping reliable, need not to peel off the suspended insulated guide wire strain clamp of the band steel core of wire insulation.
The utility model comprises the body that is provided with wedge cavities, link plate is connected on the body, the wedge cavities lateral wall of body is provided with groove, form the body construction of cross section near " C " font, the wedge core that uses is arranged in the movable cooperation of wedge cavities in pairs, and suspended insulated guide wire then places this that clamping between wedge core is fixed.
Wire clip body of the present utility model adopts " C " font structure, and the concentrated stress in the time of can reducing the wedge core and contact with body improves the intensity of wire clip body, and it is more reasonable to design, and the while can be saved body production materials.The direct clamping lead of wedge core, chucking power is stronger, avoids the lead slippage, need not to peel off the suspended insulated guide wire requirement that insulating barrier just can reach the mounting strap steel core.And the wedge core can make wire clamp draw tighter and tighter, and the fail safe of circuit operation is had better guarantees, installs also easily, and Operation and Maintenance is easy.The wedge core can also be changed according to the specification of lead, and wire clamp can be dismantled repeated use, reduces cost.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the front view of embodiment.
Fig. 2 is the A-A generalized section of Fig. 1.
Fig. 3 is the schematic diagram of body among Fig. 2.
Fig. 4 is the vertical view of below wedge core among Fig. 1.
Embodiment: as shown in Figure 1 to Figure 3, be provided with wedge cavities 3 in the body 1, link plate 4 is connected on the body 1, is used for being connected with other gold utensil whole wire clamp is fixed on electric pole.Wedge cavities 3 lateral walls of body 1 are provided with groove 5, form the body construction of cross section near " C " font.The wedge core 2 that uses is arranged in 3 movable cooperations of wedge cavities in pairs, and 9 of suspended insulated guide wires place this that clamping between wedge core 2 is fixed.In fact, on wedge core 2, expose to wedge cavities 3 positions and also be provided with flange briquetting 6, bolt assembly 7 connects clamp flange briquettings 6, constitutes wedge core clamping pre-tightening mechanism.Make wedge core 2 begin that suspended insulated guide wire 9 has just been had pretightning force like this, make lead and wedge core 2 be difficult to produce and slide, increased grip greatly lead.And flange briquetting 6 compresses the turning effort of back may command wedge core 21 li of body, and wedge core 2 can only be moved forward, and reduced because the frictional resistance that rotation produces has strengthened the grip to lead, reduced the destruction to body 1 simultaneously.The quantity of flange briquetting 6 then can require to make a plurality of according to the pretightning force of 2 pairs of leads of wedge core.
As shown in Figure 4, present embodiment gathers on the sandwich serface of wedge core 2 and is provided with friction enhanced muscle 8, can further strengthen the grip to lead.Then be made as the inclined-plane in the end of wedge core 2 and the contact-making surface place of suspended insulated guide wire 9, can make lead be difficult for producing serious local deformation, reduce damage insulating barrier.
When installing and using, suspended insulated guide wire 9 usefulness wire grips are strained, live core with 2 clampings of wedge core then, be connected the clamping pretension by flange briquetting 6 with bolt assembly 7, the wedge core 2 that clips lead is inserted in the wedge cavities 3 of body 1, and the remainder of lead then can be put into by the groove 5 of body 1 sidewall.Knock wedge core 2 rear portions gently, make it slightly tight, remove wire grip again, can be increasing trend to the chucking power of suspended insulated guide wire 9 under deadweight and tensile force effect, clamping is very reliable.Generally also scribble lubricating oil, move more smooth and easy at the contact-making surface place of wedge core 2 and wedge cavities 3.4 of link plates are to be used for being connected with other gold utensil whole wire clamp is fixed on electric pole.
