[0025] The shell fragment 2 at least includes following two structures:

[0026] The first structure is: the number of annular base 21 is one, and the guide connection 23 is bent and formed in the elastic arm 22 end, and its structure is relatively simple, and can realize the purpose of enhancing the high on performance of center needle 1.

[0027] The second structure is: the number of annular base 21 is two, and the guide connection 23 is bent and formed in the elastic arm 22 middle, and the guide connection 23 both ends are integrally connected with two annular base 21, and its structure is extremely stable, and can enhance the elastic deformation ability of elastic arm 22, and can further improve the high on performance of the utility model.

[0028] The embodiment is as preferred embodiment, and the shell fragment of using is the second structure above.

[0029] The center needle 1 and shell fragment are made of high on performance material (such as superconducting copper).

[0030] The head of the center pin 1 is provided with a spherical guide surface 12. This spherical guide surface 12 has a good automatic guiding function. That is, when the center pin 1 is inserted into the guide groove of the paired center conductor, the spherical guide surface 12 first contacts the front opening of the guide groove. At this time, the spherical guide surface 12 plays an automatic guiding function, enabling the center pin 1 to be quickly and accurately inserted into the guide groove of the paired center conductor, improving the smoothness of operation. Of course, the head of the center pin 1 can also be provided with an arc-shaped guide surface, which can also improve the automatic guiding function, but its function is slightly lower than that of the spherical guide surface 12.

[0031] The width of the limiting groove 11 is greater than the length of the spring piece 2, allowing the spring piece to slide in the limiting groove 11. When the center pin 1 is inserted into the guide groove of the paired center conductor, the elastic arm 22 of the spring piece 2 is pressed down from the outside to the inside, and the length of the elastic arm 22 increases, thereby causing the two annular bases 21 to move to both sides respectively, that is, the length of the entire spring piece 2 is stretched.

In practical use, the metal core of the first conductor 71 is inserted into the wiring groove 13 at the tail end of the center pin 1 and fixed by soldering. The solder can extend to the beveled surface 14, which increases the contact area between the solder and the tail end of the center pin 1, thereby enhancing the welding quality and forming a stable weld between the first conductor 71 and the tail end of the center pin 1, resulting in stable electrical conductivity. Furthermore, the solder leaks out through the solder drain hole 15, further enhancing the welding quality, improving welding efficiency, and effectively avoiding defects such as false soldering / incomplete soldering.

[0034] The center pin 1 has a first groove 16 at its rear. The insulator 4 is partially embedded in and fixed in the first groove 16, thereby enhancing the stability of the assembly structure of the insulator 4 and the center pin 1, so that the insulator 4 and the center pin 1 are firmly assembled together to form a structurally stable whole, which facilitates subsequent assembly.

[0035] The outer plastic seat 5 is externally provided with a groove 51 for facilitating hand gripping, and the two side walls of the groove 51 are provided as inclined surfaces.

[0036] The outer conductor 3 is externally provided with a positioning notch 31 at the lower end, and the outer plastic seat 5 is partially filled in the positioning notch 31, which can ensure the stability of the assembly structure.

[0037] The groove 51 is further provided with a plurality of reinforcing ribs 511 for increasing strength, which can increase strength and improve product quality.
