[0034] Example 1

[0035] like Figure 1-Figure 3 As shown, Figure 1is a schematic diagram of the three-dimensional structure of the floating connection terminal; Figure 2 is a cross-sectional schematic diagram of a floating connection terminal; Figure 3 The floating connector of the present application comprises a carrier 1, a connector 2, and a first contact 3. The connector 2 extends through the carrier 1 and is movable relative to the carrier 1. The first contact 3 is disposed within the carrier 1 and abuts against the connector 2.

[0036] Refer to it again Figure 4-Figure 7 As shown, Figure 4 is a schematic diagram of the three-dimensional structure of the carrier 1; Figure 5 is a cross-sectional schematic diagram of the connector 2; Figure 6 is a schematic diagram of the three-dimensional structure of the second contact body 23; Figure 7 This is a front view of the second contact body 23. The carrier body 1 is provided with a through hole 11 and a first receiving groove 12. The through hole 11 extends longitudinally along the carrier body 1. The connector 2 is located within the through hole 11 and is movable within the through hole 11. The first receiving groove 12 surrounds the through hole 11. For example, if the through hole 11 has a circular cross-section, the first receiving groove 12 also has a circular cross-section. Furthermore, the first receiving groove 12 is connected to the through hole 11. The first receiving groove 12 has a bottom wall 121 and side walls 122. The first contact body 3 is located on the surface of the side walls 122 of the first receiving groove 12. In this embodiment, only one side wall 122 is provided with the first contact body 3. Furthermore, the outer surface of the carrier body 1 is provided with tooth patterns 13, which facilitate connection with other components.

[0037] The connector 2 includes a connecting tube 21 and a connecting block 22. The connecting tube 21 is located within the through-hole 11, with both ends of the connecting tube 21 extending outside the through-hole 11. The connecting block 22 is annularly disposed on the outer surface of the connecting tube 21 and is movably disposed within the first receiving groove 12. The first contact body 3 abuts the connecting block 22. Furthermore, a spacing L is provided between the outer wall surface 221 of the connecting block 22 and the bottom wall 121 of the first receiving groove 12. This spacing L provides space for the connecting block 22 to move. In other words, the connecting tube 21 can move 360° around the center of the through-hole 11 within the through-hole 11 to accommodate deviations at different positions. Furthermore, the connector 2 also includes a second contact body 23 and a fixing sleeve 24. The second contact body 23 is disposed inside the connecting tube 21 (i.e., in a hollow position). A support platform 211 is provided at one end of the connecting tube 21. One end of the second contact body 23 is located on the support platform 211, and the other end of the second contact body 23 is located at the end of the connecting tube 21 away from the support platform 211. The fixing sleeve 24 is mounted on the end of the connecting tube 21 away from the support platform 211 and the end of the second contact body 23 away from the support platform 211. The fixing sleeve 24 fixes the second contact body 23 in the connecting tube 21. It should also be noted that the second contact body 23 also has a hollow structure, which facilitates the insertion of an external pin into the hollow structure to achieve contact with the second contact body 23.

[0038] Please review Figure 6 and Figure 7 The second contact body 23 includes a first contact area 231, multiple connecting strips 232 and a second contact area 233. The fixing sleeve 24 is sleeved on the end of the connecting tube 21 away from the supporting platform 211 and the first contact area 231. One end of the connecting strip 232 is connected to the first contact area 231, and the other end of the connecting strip 232 is connected to the second contact area 233. The first contact area 231 and the second contact area 233 are arranged opposite each other. Multiple connecting strips 232 are distributed at intervals between the first contact area 231 and the second contact area 233. The second contact area 233 is located on the supporting platform 211.

[0039] The connecting strip 232 has a first protrusion 2321 at its end near the first contact region 231. The first protrusion 2321 projects outward and abuts the wall of the connecting tube 21. It should be noted that the cross-sections of the first and second contact regions 231, 233 in this embodiment are circular; therefore, the inside of the circle is defined as the interior, and the outside of the circle is defined as the exterior. Furthermore, the connecting strip 232 has a second protrusion 2322 at one end near the second contact region 233. Similarly, the second protrusion 2322 also projects outward and abuts the inner wall of the connecting tube 21. When the pin is inserted, the pin exerts an outward expansion force on the first contact region, causing it to deform and, in turn, cause the multiple first protrusions 2321 to expand outward. When the pin is fully inserted, the second protrusion 2322 is also expanded outward.

[0040] In specific applications, there is an angle at the connection between the multiple connecting strips 232 and the first contact area 231 and / or the second contact area 233. The angle in this embodiment is an acute angle, that is, the multiple connecting strips 232 are distributed at an inclined interval between the first contact area 231 and the second contact area 233.

[0041] Refer to it again Figure 8 and Figure 9 As shown, Figure 8 is a schematic diagram of the three-dimensional structure of the first contact body; Figure 9The figure is another schematic diagram of the three-dimensional structure of the first contact body. The first contact body 3 includes a support ring 31 and a plurality of conductive plates 32. The support ring 31 and the plurality of conductive plates 32 are both located within the first receiving groove 12. The plurality of conductive plates 32 are spaced apart on the inner wall 311 of the support ring 31. The plurality of conductive plates 32 abut against the sidewall 122 of the first receiving groove 12 and the surface of the connecting block 22. Furthermore, the conductive plates 32 have a first protrusion 321 and a second protrusion 322 on the side away from the support ring 31. The first protrusion 321 and the second protrusion 322 extend in opposite directions. That is, with the support ring 31 as the boundary, the first protrusion 321 extends upward and extends beyond the upper surface of the support ring 31, while the second protrusion 322 extends downward and extends beyond the lower surface of the support ring 31. The first protrusion 321 abuts against the sidewall 122 of the first receiving groove 12, while the second protrusion 322 abuts against the surface of the connecting block 22. By cooperating with multiple conductive pieces 32, the number of current conduction points between the connection block 22 and the side wall 122 of the first receiving groove 12 is increased, thereby improving the current conduction efficiency. Furthermore, a portion of the conductive pieces 32 is disposed on the inner wall 311 of the support ring 31, while another portion of the conductive pieces 32 is spaced apart and distributed on the outer wall 312 of the support ring 31, further increasing the number of current conduction points between the connection block 22 and the side wall 122 of the first receiving groove 12. In this embodiment, all conductive pieces 32 have the same structure. It is understood that in order to provide the conductive piece 32 with a first protrusion 321 and a second protrusion 322, the conductive piece 32 can be twisted in the vertical direction on the side away from the support ring 31. The twisting angle does not need to be too large, and only needs to be sufficient to form the first protrusion 321 and the second protrusion 322.

[0042] In this embodiment, the first contact body 3 and the second contact body 23 are both made of a material with high conductivity and high yield strength, and the material is an existing material, such as copper.

[0043] During specific use, current can be conducted between the carrier 1 , the first contact body 3 , the connecting body 2 and the second contact body 23 .

[0044] To sum up, by adding a spacing L between the connecting block and the bottom wall of the first accommodating groove, the connecting tube and the connecting block can move within the spacing L. During the movement, the first protrusion 321 of the first contact body remains in contact with the side wall of the first accommodating groove, and the second protrusion remains in contact with the connecting block, thereby achieving a small-range offset effect of the connecting body, which is conducive to overcoming the deviation problem and can also improve the efficiency of plugging and unplugging.

[0045] Example 2

[0046] The difference between this embodiment and the first embodiment is that there are two first contact bodies 3 , both of which are located in the first receiving groove 12 and on both sides of the connecting block 22 ; the two first contact bodies 3 have the same structure.

[0047] The above description is merely an embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be included within the scope of the claims of the present invention.
