It should be noted that: the first connection terminal 41 may be integrally formed with the second connection terminal 42, and the second flange 43 may be integrally formed with the first connection terminal 41.
As shown in fig. 2, the center of the first connection end 41 is provided with a jack; the lower end of the lead 31 is provided with a first conical surface 311; a second conical surface 411 matched with the first conical surface 311 is arranged in the plug hole, and the end part of the lead 31 is of a conical surface structure, so that the inner side of the plug hole is a convex conical surface tightly matched with the conical surface of the end part of the lead 31, and the structural parameters of the convex conical surface are matched with the conical surface of the end part of the lead 31; the lead 31 is inserted into the insertion hole through the first taper 311, and the connection is tighter through the mutual matching of the tapers, so that good electrical connection can be realized.
The included angle between the first taper surface 311 and the vertical plane is 0.5-2.0 deg.
It should be noted that: the length of the tapered portion of the lower end of the lead 31 is related to the transmission current, and an excessively small current density can reduce the heat generation of the lead 31, but increase the volume of the connection portion between the lead 31 and the terminal 4; an excessive current density can reduce the volume of the connection portion, but can increase the heat generation of the connection portion; in general, the concentration of the water-soluble polymer can be 0.5-2.0A/mm2Is estimated.

As shown in fig. 3, the first connection terminal 41 is an Ω -shaped terminal, and a first slit 412 is formed at one side of the Ω -shaped terminal, so that the first connection terminal can deform to a certain extent when being pressed externally, and can better contact with the lead 31 of the inner sleeve 3; the second connection end 42 comprises a first connection piece 421 and a second connection piece 422, the first connection piece 421 and the second connection piece 422 are symmetrically fixed at two sides of the first gap 412, and the first connection piece 421 and the second connection piece 422 are symmetrically provided with fixing holes for fixing the soft copper strip by matching with bolts, when in installation, the soft copper strip is fixed between the first connection piece 421 and the second connection piece 422 by the bolts penetrating through the fixing holes, and the structure can realize connection with the soft copper strip of the superconducting electrified conductor 2 and simultaneously lead the omega-shaped end to generate certain deformation by the bolts; the second flange 43 is correspondingly provided with a second gap 431 having the same shape as the first gap 412, so that the deformation of the omega-shaped end can not be influenced when the second connecting end 42 is pressed.
The wall thickness of the omega-shaped end is 5-15mm, the strength is insufficient when the omega-shaped end is too thin, and the omega-shaped end is difficult to compress through the outside when the omega-shaped end is too thick; the thickness of the first 421 and second 422 connectors may be the same as the wall thickness of the omega-shaped tip.
The width of the first slot 412 is 4-6mm, and too narrow the amount of deformation is insufficient, and too wide the conductor contact area of the omega-shaped terminal is reduced.
In this embodiment, the thickness of the side wall of the Ω -shaped end is 10mm, and the taper of the inner side surface of the Ω -shaped end matches with the taper of the lead 31 to be 1 degree of protrusion; the first and second connection members 421 and 422 have a thickness of 10mm and a height of 20 mm.

Because the end part of the lead 31 of the sleeve 3 is a conical surface and is just opposite to the omega-shaped end of the terminal 4, the lead 31 can be directly pressed into the omega-shaped end when the sleeve 3 is installed; as the first tapered surface 311 at the end of the lead 31 contacts the second tapered surface 411 at the inner side of the Ω -shaped tip, the Ω -shaped tip will deform outwards when being pressed in, and the bolt on the second connection tip 42 will prevent the deformation; the downward pressing of the first flange 33 interacts with the screw pressing of the second connection terminal 42 of the terminal 4, so that a good electrical contact between the omega-shaped terminal and the lead 31 of the bushing 3 is ensured.
The above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the same; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions in the embodiments of the present application.
