Abstract
A core clamp for a carbon fiber composite core wire is characterized in that the core clamp comprises a casing with a hollow cavity, wherein a conical clamp piece fitted with the hollow cavity of thecasing is arranged inside the casing, and a screw cap with a hollow cavity is arranged at one end of the casing, is butted against one end of the conical clamp piece and is fastened with the threads of the hollow cavity of the casing. The steel casing with the inner conical cavity is designed according to the size of the outer diameter of a core rod of the composite core wire, a gap is reserved between the casing and the composite core wire, the core rod of the composite core wire is inserted into the steel casing, the conical clamp piece is inserted into the gap between the casing and the composite core wire, and the screw cap with the hollow cavity is sheathed outside the core rod of the composite core wire and is screwed down through threads. Under the combined action of the axial forceof thread screwing and the radial clamping force of the conical clamp piece, the core clamp clamps the core rod of the composite core wire more and more tightly, so that the radial clamping force ofthe core clamp is always larger than the axial pulling force, the traction force is transmitted, and higher safety factor is achieved.
Description
Technical field
The utility model relates to a kind of Electric wire clamp, a kind of clamping jig that is exclusively used in carbon fiber composite core wire.
Background technology
Because carbon fiber clad aluminum twisted wire (ACCC lead) adopts fine aluminium, quality is softer, wire external layer is the soft aluminium of annealing that the trapezoid cross section forms, inner for there being certain space in the middle of the carbon fiber composite core rod, mandrel surface is smooth and scribble one deck high-temperature insulation grease, therefore, traction ACCC/TW lead and with it dock, a very crucial specification requirement is arranged, after promptly this lead is subjected to drawing tension, the power that outer aluminum steel is subjected to can not be delivered on the plug, causes outer aluminum steel constantly to extend, and carbon fiber rod shrinks relatively, as adopt conventional method to connect lead, in case carbon fiber core is retracted to a certain degree even goes to the snakeskin cover outer end that does not stress, what the snakeskin cover was caught so only is outer aluminium lamination, will run the line accident; The perhaps slippage of the carbon fiber core of lead inside and outer aluminium lamination and change original performance of lead strengthens difficulty of construction, and causes waste.According to the characteristics of this lead, the core that before the construction lead supplier is provided sticks into has gone test, and through calculating, lead is in engineering construction, and average drawing tension reaches 40kN, and instantaneous drawing tension reaches 50kN.And the core card that supplier's company and U.S. CTC company provide is two semicircular structures, with bolted core card, can not produce enough frictional force and come transmitting tractive power, it bears pulling force less than 20kN through test, the generation relative displacement of promptly sliding of core card and plug.Can not satisfy construction requirement.
Summary of the invention
The technical problems to be solved in the utility model is, design a kind of wire stylet card of direct clamping carbon fiber clad aluminum twisted wire plug, make it in the backguy traction construction, make plug and outer cover sync pulling, tension force transmits synchronously, drawing tension when intensity meets or exceeds construction, and leave bigger coefficient of safety.
Carbon fiber composite core wire core card, its feature comprises the sleeve pipe of a band lumen, be provided with the taper fixture block with the mutual fit of its lumen in the sleeve pipe, when the nut that an end of sleeve pipe is established a band cavity holds contact mutually with an end of taper fixture block and the screw thread of sleeve pipe lumen tighten up mutually.
According to compound core conducting wire plug external diameter size, design the steel sleeve in a band inner cone chamber, sleeve pipe and compound core conducting wire leave the gap, the compound core conducting wire plug inserts in the steel sleeve, the taper fixture block is inserted among the space between compound wire plug and the steel sleeve, nut sleeve with the band cavity screws at compound wire mandrel outer and screw thread, under the acting in conjunction of the radially clamping force of axial force that screw thread screws and taper fixture block, the core card blocks the compound core conducting wire plug more tight, the radially clamping force that makes the core card makes tractive effort transmitted forever greater than axial motive force.

Fig. 3 is the utility model user mode schematic diagram.
Embodiment
Shown in Fig. 1～2, the utility model is made up of sleeve pipe 5, taper fixture block 6 and nut 1, and an end of sleeve pipe 5 lumens is internal thread chamber 4, and the nut 1 of band cavity 2 is established external screw thread 3, and the internal thread of nut 1 and sleeve pipe 5 just in time matches and screws.Taper fixture block 6 be tube wall by thin even thickening, but the constant fixture block of cavity 7 diameters.6 two of the employings of taper fixture block are closed up when packing sleeve pipe 5 into, end plug by the band internal thread chamber 4 of sleeve pipe 5 is gone into, cavity 2 diameters of nut 1 and cavity 7 equal diameters of taper fixture block 6, become different specification series according to carbon fiber composite core wire plug 10 size design, the lumen diameter should be bigger slightly than carbon fiber compound wire plug.Two taper fixture blocks 6 close up when filling in the sleeve pipe 5 shown in Fig. 2 a, and the spacing 8 between two taper fixture blocks 6 is 1～4mm, also can be with three block-shaped identical corresponding closing up of taper fixture block.
Referring to shown in Figure 3, compound wire 9 is peelled off skin, plug 10 appropriate length in keeping, and tighten up standby with friction tape 11 wrappings at notching edge, two taper fixture blocks 6 are closed up relatively from the screw thread mouth of sleeve pipe 5 fill in, plug 10 is penetrated the cavity 7 and the nut cavity 2 of taper fixture block from the other end of sleeve pipe, be about to taper fixture block 6 when screwing nut 1 and progressively advance progressively and clamp, to the tension force of clamping force, and leave suitable coefficient of safety greater than when construction traction.
Claims (6)
1, carbon fiber composite core wire core card, its feature comprises the sleeve pipe of a band lumen, be provided with the taper fixture block with the mutual fit of its lumen in the sleeve pipe, when the nut that an end of sleeve pipe is established a band cavity holds contact mutually with an end of taper fixture block and the screw thread of sleeve pipe lumen tighten up mutually.
