Description
Technical field
Repairing, the gold utensil that continues used when the utility model relates to a kind of high temperature wire breakage, disconnected strand or joint refer to that specifically a kind of high temperature wire is with the bar that continues.
Background technology
When lead generation breakage, disconnected thigh or conductor length are not enough, need repair or continue lead, the repairing of traditional normal temperature lead or connecting method often cause the joint temperature significantly to raise, especially for the higher high temperature wire of self continuous service temperature, the joint temperature raises and directly causes the intensity at the position of continuing not reach instructions for use.
The utility model content
At the problems referred to above, the purpose of this utility model is to provide a kind of intensity height that continues, high temperature wire easy to use with the bar that continues.
For achieving the above object, technical solution of the present utility model is:
A kind of lead is with the bar that continues, comprise some groups of internal layer preformed armor rodses and some groups of outer preformed armor rodses, these some groups of internal layer preformed armor rodses are wound in outside the lead that is continued, these some groups outer preformed armor rodses are wound in outside the internal layer preformed armor rods, be equipped with the helical form bending on internal layer preformed armor rods and the outer preformed armor rods, helical form bending on some groups of internal layer preformed armor rodses is coupling mutually, the preforming internal diameter of this helical form bending is less than the wire diameter that is continued, helical form bending on some groups of outer preformed armor rodses is coupling mutually, and the preforming internal diameter of helical form bending is less than the preforming internal diameter of helical form bending on the internal layer preformed armor rods.
Further, described every group of internal layer preformed armor rods formed by some helical form aluminium alloy preformed armor rods bondings.
Further, described internal layer preformed armor rods inner surface is bonded with conduction sand.
Further, described every group of outer preformed armor rods formed by some helical form aluminium alloy preformed armor rods bondings.
Further, described outer preformed armor rods inner surface is bonded with conduction sand.
Further, described internal layer preformed armor rods is provided with the installation colour code.
Further, described outer preformed armor rods is provided with the installation colour code.
The damaged lead because the inside and outside two-layer aluminium alloy preformed armor rods of the utility model employing continues, guaranteed that the splicing point heat dispersion is good and then guaranteed to continue intensity, avoid the splicing point temperature too high and the intensity that continues is reduced, be particularly useful for the higher high temperature wire of self continuous service temperature; In addition,, only need lead is got final product along bending to twine owing to set in advance the helical form bending on the preformed armor rods, easy to use; The preforming internal diameter of helical form bending is less than the wire diameter that is continued on the internal layer preformed armor rods, the preforming internal diameter of helical form bending is less than the preforming internal diameter of helical form bending on the internal layer preformed armor rods on the outer preformed armor rods, make the internal layer preformed armor rods produce grip force to the lead that is continued, outer preformed armor rods produces grip force to the internal layer preformed armor rods, and it is stable that damaged lead is continued; In addition, the inner surface of internal layer preformed armor rods, outer preformed armor rods all is bonded with conduction sand, further increases frictional force, guarantees to continue intensity.

Fig. 2 is the structure chart of one group of internal layer preformed armor rods;
Fig. 3 is the structure chart of one group of outer preformed armor rods.
Embodiment:
Specify the utility model below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of lead is with the bar that continues, comprise some groups of internal layer preformed armor rodses 1 and some groups of outer preformed armor rodses 2, some groups of internal layer preformed armor rodses 1 are wound in the lead 3 that is continued, 4 outsides, some groups of outer preformed armor rodses 2 are wound in internal layer preformed armor rods 1 outside, as shown in Figure 2, every group of internal layer preformed armor rods 1 has aluminium alloy preformed armor rods 11 bondings of even helical form bending to form by several strips, and the pitch of the bending of the helical form on some groups of internal layer preformed armor rodses 1 equates, the preforming radius equates, some groups of internal layer preformed armor rodses 1 are mated mutually, be wrapped in the outer rear flank of lead and form hollow tubular, the preforming internal diameter of this helical form bending is slightly less than the wire diameter that is continued, after making internal layer preformed armor rods 1 be wrapped on the lead lead is formed even normal pressure, helical form bending on the internal layer preformed armor rods 1 changes normal pressure to lead 3 into, 4 grip makes lead 3,4 continue stable; As shown in Figure 3, every group of outer preformed armor rods 2 has aluminium alloy preformed armor rods 21 bondings of even helical form bending to form by several strips, and the pitch of the helical form bending on some groups of outer preformed armor rodses 2 equates, the preforming radius equates, some groups of outer preformed armor rodses 2 are mated mutually, be wrapped in internal layer preformed armor rods 1 outer rear flank and form hollow tubular, the preforming internal diameter of this helical form bending is slightly less than the preforming internal diameter on the internal layer preformed armor rods 1, outer preformed armor rods 2,1 socket of internal layer preformed armor rods are stablized, further strengthened the stability that continues of the lead 3,4 that continued;
Be to increase coefficient of friction, improve the bar that continues to the grip force of the lead 3,4 that continues, the inner surface of internal layer preformed armor rods 1, outer preformed armor rods 2 all is bonded with conduction sand.
In addition, be respectively equipped with on internal layer preformed armor rods 1 and the outer preformed armor rods 2 colour code 12,22 is installed, during use, breaking point with lead is the center earlier, make the installation colour code of breaking point to homogeneous group internal layer preformed armor rods 1, therefrom the mind-set two ends are wrapped in internal layer preformed armor rods 1 on the lead 3,4, and Using such method is wrapped in some groups of internal layer preformed armor rodses 1 on the lead 3,4, some groups of internal layer preformed armor rodses are formed lead is trapped among tubulose in the chamber; According to said method some groups of outer preformed armor rodses 2 are wrapped in outside the internal layer preformed armor rods 1 again, outer preformed armor rods 2 are formed internal layer preformed armor rods 1 is trapped among tubulose in the chamber.
