Abstract
The utility model discloses a reinforced plastic insulating strain resistant wire clamp, used for clamping outdoor overhead insulating conducting wires. The utility model comprises a pull rod, a shell cover, and a wedge-shaped plugging block. In the utility model, the pull rod and the shell cover have integral structure; a wedge-shaped channel is arranged between the shell cover and the pull rod; the tail part of the pull rod is provided with a U-shaped joint on which circular pin holes are arranged; the pitch of the wedge-shaped plugging block is matched with the pitch of the wedge-shaped channel; the bottom part of the wedge-shaped plugging block forms an arched groove on which an antiskid rib is arranged in the lateral direction. The utility model has the advantages of strong clamping force, favorable insulating property, firm self locking property, convenient operation, etc., used for clamping outdoor overhead cable conducting wires.
Description
The utility model relates to a kind of clamping device that is used for the outdoor aerial insulated conductor, specifically, relates to a kind of reinforced plastics insulation strain clamp.
In the prior art, the strain clamp that is used for outdoor overhead transmission line is generally made by metal material, forms as screw bolt-type strain clamp commonly used and comprises triangle tubulose body, pressing plate and U type screw, has on the wire clamp and fixedly uses circular port.During use, allow cable pass triangle tubulose body, screw U type screw, pressing plate is pressed abd fixed on cable in the strain clamp.It is applicable to the clamping of general cable, but when cable clamping pulling force is big, can cause that cable moves in anchor clamps, damage the cable insulating covering, wire clamp is contacted and charged with nuditing wire, electric current draws by metal cross arm and electric pole metal and climbs inflow surface, causes people and livestock electric shock casualty accident near electric pole easily.At the weak point of above-mentioned prior art, done improvement on online clamping structure of the utility model and the material.
The purpose of this utility model provides that a kind of chucking power is very strong, easy to use, insulating properties is good, self-locking performance good and easily manufactured reinforced plastics insulation strain clamp.
Embodiment of the present utility model is, this reinforced plastics strain clamp that is used for the outdoor aerial insulated conductor, comprise pull bar, case, with the wedge shape chock, the case that is characterized in pull bar and its head is the overall structure that fuses, constitute wedgy passage between case and the pull bar, the height of wedgy passage increases gradually to afterbody from the head, the afterbody of pull bar is a u shaped connector, have two coaxial circles pin-and-holes on the u shaped connector, the gradient of wedge shape chock and the gradient of wedgy passage are complementary, the bottom of wedge shape chock is arcuate recess, and the anti-skidding muscle of transverse arrangement of turbo is arranged on the arcuate recess.Its operation principle with using method is: the u shaped connector of the afterbody of pull bar is passed pin hole with pin be connected with cross-arm on the electric pole, insulated cable conductor is passed wedgy passage from the head, with drawtongs lead is strained, the wedge shape chock is filled in the wedgy passage, make the arcuate recess of wedge shape chock bottom push down cable conductor, slightly firmly beat chock, make it to push down the cable conductor in the wedgy passage, unclamp drawtongs, insulated cable conductor is overhanging automatically, lead drives the wedge plug piece, and insulated cable conductor is tightly pushed down.In the arcuate recess of wedge shape chock bottom anti-skidding muscle is arranged, increased the frictional force between lead and the wedge shape chock, guarantee that lead can not slide in groove.Zhang Deyue is tight for the aerial cable lead, and chock is locked also tightly more to lead, has so just played self-locking action.Because the case of pull bar and its head is an overall structure, so chucking power is strong especially.For the strain clamp of the present utility model of clamping 70～120mm insulated cable conductor, after measured, can stand 2.5 tons pulling force, and not be damaged.
The case and the wedge shape chock of pull bar of the present utility model and its head are made of long glass fibres reinforced plastics.Long glass fibres reinforced plastics has excellent physical and mechanical properties, guarantees that the utility model has very strong chucking power to cable conductor, has good insulation property simultaneously.
The utility model can be made different size to adapt to the requirement of different-diameter insulated cable conductor, is widely used for the needs that set up of outdoor aerial lead.
Compared with the prior art the utility model has the following advantages: the chucking power extra-heavy can be applicable to the needs of the clamping of different thicknesses cable conductor.Easy to use, cable conductor is placed in the wedgy passage and again the wedge shape chock is filled in passage, slightly firmly strikes tight chock and just finishes.Self-locking action is good, and the outside tension force of aerial cable lead is big more, and chock is locked tightly more to lead.Anti-skidding muscle in the groove of wedge shape chock bottom has increased the frictional force between lead and the chock, guarantees that lead can not slide in groove.Adopt the reinforced plastics overall structure, good insulation preformance, easily manufactured.
Now in conjunction with the accompanying drawings an embodiment of the present utility model is done into explanation.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structure chart of pull bar of the present utility model and case.
Fig. 3 is a wedge shape chock face upwarding assumption diagram of the present utility model.
Number in the figure is represented:
The 1-case, 2-wedge shape chock, 3-pull bar, 4-U type joint, 5-pin hole, 6-wedgy passage, 7-arcuate recess, the anti-skidding muscle of 8-.
This reinforced plastics insulation strain clamp that is used for clamping outdoor aerial insulated conductor, comprise pull bar 3, case 1 and wedge shape chock 2, be characterized in: the overall structure of case 1 for fusing of pull bar 3 and its head, constitute wedgy passage 6 between case 1 and the pull bar 3, the height of wedgy passage 6 increases gradually to afterbody from the head, the afterbody of pull bar 3 is a u shaped connector 4, have two coaxial circles pin-and-holes 5 on the u shaped connector 4, the gradient of the gradient of wedge shape chock 2 and wedgy passage 6 is complementary, the end of wedge shape chock 2, be arcuate recess 7, and the anti-skidding muscle 8 of transverse arrangement of turbo is arranged on the arcuate recess 7.Pull bar 3, case 1 and wedge shape chock 2 are made of the long glass fibres plastics.
