Abstract
The utility model relates to a splicing armor clamp for a carbon fiber complex core flexible aluminum stranded conductor. The splicing armor clamp comprises an outer pipe and a connecting piece connected in a cavity of the outer pipe; the connecting piece comprises a butt joint positioned in the center, wedge type outer dies symmetrically connected at two ends of the butt joint in a threaded manner, and additional pipes connected at outer end portions of the wedge type outer dies; an annular sliding loop abutted with the two wedge type outer dies is disposed in a cavity of the butt joint; wedge type inner dies are respectively disposed in the wedge type outer dies in an inserting manner; the stranded conductor successively passes through cavities of the sliding loop, the wedge type inner dies and the additional pipes from inside to outside and outwardly extends; and the conicity of each wedge type inner die is 1.15-1.25. The splicing armor clamp has the beneficial effects that the size of the splicing armor clamp is obviously decreased, the splicing armor clamp can pass through a pulley conveniently, and the stranded conductor in the armor clamp is not easily broken; and the splicing armor clamp is high in intensity, high in grip strength, good in corrosion resistance and good in safety.
Description
Technical field
The utility model relates to a kind of aluminum conductor composite core splicing fitting.
Background technology
Electric armour clamp will stand the baptism of ice, snow, storm on the transmission line of long-time running, strong wind, sleet, icing easily cause the faults such as wire ice-shedding, phase fault, wire collision lightning conducter, so electric armour clamp must possess higher mechanical strength and enough coefficient of safetys.The ubiquitous problem of existing gold utensil is: breaking load power is less, and intensity is low, and grip is less, and fail safe is poor.
In addition, the butt joint two ends of existing gold utensil are provided with connection joint, make the overall length of gold utensil be greater than 1m, and gold utensil overall length is long, be unfavorable for the wire process coaster on gold utensil, and twisted wire easily fracture.
Based on the problems referred to above, be badly in need of the splicing fitting that a kind of length of design is short, intensity is high.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of aluminum conductor composite core splicing fitting.
The utility model solves the technical scheme that its technical problem adopts: a kind of aluminum conductor composite core splicing fitting, comprise outer tube and be connected in the connector in outer lumen, connector comprises and is positioned at central butt joint, symmetry is threadedly connected to the wedge type external mold at butt joint two ends, be connected in the benefit pipe of wedge type external mold outer end, in abutment cavity, be provided with the annular sliding ring with two equal butts of wedge type external mold, in wedge type external mold, be inserted with wedge type internal mold, twisted wire is arranged in sliding ring from inside to outside successively, wedge type internal mold, mend in the chamber of pipe and stretch out, the tapering of wedge type internal mold is 1:15～1:25.
Further, the two ends of butt joint have internal thread, and the end of the wedge type external mold being connected with butt joint is provided with external screw thread.
The beneficial effects of the utility model are: splicing fitting size obviously reduces, convenient through coaster, and the twisted wire in gold utensil is not easy to be fractureed; Intensity is high, and grip is strong, good corrosion resistance, and fail safe is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. outer tube, 2. butt joint, 3. wedge type external mold, 4. mends pipe, 5. sliding ring, 6. wedge type internal mold.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of aluminum conductor composite core splicing fitting as shown in Figure 1, comprise outer tube 1 and be connected in the connector in outer tube 1 chamber, connector comprises the wedge type external mold 3 that is positioned at central butt joint 2, symmetry and is threadedly connected to butt joint 2 two ends, the benefit pipe 4 that is connected in wedge type external mold 3 outer ends, in butt joint 2 chambeies, be provided with the annular sliding ring 5 with two wedge type external molds, 3 equal butts, in wedge type external mold 3, be inserted with wedge type internal mold 6, twisted wire is arranged in successively from inside to outside sliding ring 5, wedge type internal mold 6, mends in the chamber of managing 4 and stretch out.The tapering of wedge type internal mold 6 is 1:15～1:25, makes the intensity of gold utensil high, and grip is strong, and the clamping of twisted pair wire is effective.
The two ends of butt joint 2 have internal thread, and the end of the wedge type external mold 3 being connected with butt joint 2 is provided with external screw thread.
During practical operation, twisted wire is arranged in successively from inside to outside to sliding ring 5, wedge type internal mold 6, mends in the chamber of managing 4 and stretch out, turn butt joint 2, the 3 not turns of wedge type external mold, the wedge type external mold 3 at two ends moves until prop up sliding ring 5 to the inside symmetrically under threaded engagement, wedge type external mold 3 is painstaking consistent, and stressed even, connector is easy for installation.After installing, the overall length of gold utensil is 70 or 80cm, and length shortens greatly, convenient through coaster, and the twisted wire in gold utensil is not easy to be fractureed.
Splicing fitting is carried out respectively to following testing experiment:
1, the grip strength testing of splicing fitting
By GB/T2317.1-2008 < < electric armour clamp mechanical test method part 1: mechanical test > > carries out grip strength testing to splicing fitting, twisted wire quantity is 3, and result of the test is:
Conclusion: the not slippage of the relative gold utensil of twisted wire, disconnected strand or destruction, meet standard-required.
2, the mechanical load test of splicing fitting
By GB/T2317.1-2008 < < electric armour clamp mechanical test method part 1: mechanical test > > carries out mechanical load test to splicing fitting, twisted wire quantity is 3, and result of the test is:
Conclusion: gold utensil has no obvious distortion when reaching mechanical damage load; When reaching breaking load, gold utensil destroys, and meets standard-required.
3, the vibration fatigue test of splicing fitting
Utilize vibration fatigue machine to carry out vibration fatigue test to 3 twisted wires.
Result of the test: 3 samples are respectively through 3.00 * 10
7after inferior continuous shaking test, twisted pair wire and strain hardware fitting place check, the not slippage of the relative gold utensil of twisted wire, disconnected thigh, and gold utensil has no obvious deformation failure.
Conclusion: by vibration fatigue test.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and by above-mentioned description, relevant staff can, within not departing from the scope of this utility model technological thought, carry out various change and modification completely.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to claim scope.
