[0019] As Figures 1 - 4 shown, Figure 1 It is a three-dimensional structural schematic diagram of a floating connection terminal; Figure 2 It is a disassembled state diagram of a floating connection terminal; Figure 3 It is a cross-sectional schematic diagram of a floating connection terminal; Figure 4It is a schematic cross-sectional view of the usage scenario of a floating connection terminal. The floating connection terminal includes a carrier 1, a floating member 2, a first conduction member 3, a second conduction member 4, and a third conduction member 5. The floating member 2 is disposed on the carrier 1, and the floating member 2 can move relative to the carrier 1. The first conduction member 3 is disposed between the carrier 1 and the floating member 2, and current conduction between the carrier 1 and the floating member 2 is achieved through the first conduction member 3. The second conduction member 4 and the third conduction member 5 are both disposed on the floating member 2. When an external pin is inserted into the floating member 2, both the second conduction member 4 and the third conduction member 5 are in contact with the external pin to achieve current conduction between the floating member 2 and the external pin.

[0020] The carrier 1 has a first receiving groove 11, and the first conduction member 3 is located in the first receiving groove 11. The floating member 2 can drive the first conduction member 3 to move in the first receiving groove 11 to achieve position adjustment.

[0021] The carrier 1 further has a through hole 12 which is axially formed and communicates with the first receiving groove 11. The floating member 2 has a connecting body 21 and a movable body 22. The connecting body 21 passes through the through hole 12 and can move within the through hole 12. The movable body 22 is disposed on the outer periphery of the connecting body 21, and the first conduction member 3 is disposed on the outer surface of the movable body 22. The movable body 22 can drive the first conduction member 3 to move in the first receiving groove 11. It should be noted that the connecting body 21 and the movable body 22 can be an integral structure.

[0022] Refer to Figure 5 as shown Figure 5 It is a three-dimensional structure schematic diagram of the floating member 2. The connecting body 21 has a third receiving groove 211 and a fourth receiving groove 212. Both the third receiving groove 211 and the fourth receiving groove 212 are axially formed along the connecting body 21. The fourth receiving groove 212 is located within the third receiving groove 211, that is, the third receiving groove 211 and the fourth receiving groove 212 are in a nested form. The second conduction member 4 is located in the third receiving groove 211, and the third conduction member 5 is located in the fourth receiving groove 212. During use, an external pin is inserted into both the third receiving groove 211 and the fourth receiving groove 212 at the same time, and both the second conduction member 4 and the third conduction member 5 are in contact with the external pin.

[0023] Further, the floating connection terminal further includes a limiting member 6. The limiting member 6 is located in the third receiving groove 211, and the limiting member 6 fits against the inner wall of the third receiving groove 211. One end of the limiting member 6 away from the fourth receiving groove 212 abuts against one end of the second conduction member 4. The second conduction member 4 is limited by the limiting member 6 to prevent the second conduction member 4 from sliding out of the third receiving groove 211. Specifically, a stepped structure is provided at one end of the limiting member 6 away from the fourth receiving groove 212, and the second conduction member 4 is limited by this stepped structure. Similarly, a stepped structure is also provided on the inner wall surface of the third receiving groove 211, and the other end of the second conduction member 4 abuts against this stepped structure. The two ends of the second conduction member 4 are limited by the two stepped structures respectively. In addition, the split structure of the limiting member 6 and the floating member 2 is beneficial to the assembly of the second conduction member 4. During use, the second conduction member 4 and the limiting member 6 can be assembled first, and then the two are snapped into the third receiving groove 211 as a whole. In this embodiment, the number of the limiting members 6 is two. One limiting member 6 is arranged in the third receiving groove 211, and the other limiting member 6 is arranged in the fourth receiving groove 212. The situation in the fourth receiving groove 212 is the same as that in the third receiving groove 211, which will not be elaborated here.

[0024] Refer also to Figure 6 and Figure 7 shown in Figure 6 is a three-dimensional structural schematic diagram of the first conduction member 3; Figure 7 is another three-dimensional structural schematic diagram of the first conduction member 3. The first conduction member 3 includes a support ring 31, a plurality of first elastic pieces 32 and a plurality of second elastic pieces 33. The plurality of first elastic pieces 32 are arranged at intervals at one end of the support ring 31. The plurality of first elastic pieces 32 are distributed along the circumference of the end of the support ring 31. At the same time, the plurality of first elastic pieces 32 all open towards the inside of the support ring 31; the plurality of second elastic pieces 33 are arranged at intervals at the other end of the support ring 31. The plurality of second elastic pieces 33 are distributed along the circumference of the end of the support ring 31. At the same time, the plurality of second elastic pieces 33 all open towards the inside of the support ring 31. The plurality of first elastic pieces 32 abut against one side wall of the first receiving groove 11 and one side of the outer surface of the movable body 22, and the plurality of second elastic pieces 33 abut against the other opposite side wall of the first receiving groove 11 and the other side of the outer surface of the movable body 22. Specifically, the support ring 31, the plurality of first elastic pieces 32 and the plurality of second elastic pieces 33 together form a second receiving groove 30. The movable body 22 is located in the second receiving groove 30. The support ring 31, the plurality of first elastic pieces 32 and the plurality of second elastic pieces 33 all abut against the outer surface of the movable body 22. In specific applications, the shape of the second receiving groove 30 is adapted to the shape of the movable body 22 to facilitate the assembly of the two. At the same time, the first conduction member 3 forms a wrapped form around the movable body 22, so as to improve the stability of the connection between the two and increase the contact area between the two.

[0025] The first elastic piece 32 has a first curved surface 321, which is disposed at an end of the first elastic piece 32 that is close to the support ring 31. The first curved surface 321 abuts against a side wall of the first receiving groove 11. Furthermore, the first elastic piece 32 has a second curved surface 322, which is disposed at an end of the first elastic piece 32 that is away from the support ring 31. The second curved surface 322 protrudes in a direction opposite to that of the first curved surface 321, and abuts against the outer surface of the movable body 22.

[0026] The second elastic piece 33 has a third curved surface 331, which is disposed at one end of the second elastic piece 33 closer to the support ring 31. The third curved surface 331 abuts against the other opposite sidewall of the first receiving groove 11. Furthermore, the second elastic piece 33 has a fourth curved surface 332, which is disposed at one end of the second elastic piece 33 farther from the support ring 31. The fourth curved surface 332 protrudes in a direction opposite to that of the third curved surface 331, and abuts against the outer surface of the movable body 22.

[0027] In a specific application, the first elastic piece 32 may have a plurality of first arc surfaces 321 and a plurality of second arc surfaces 322 . Similarly, the second elastic piece 33 may also have a plurality of third arc surfaces 331 and a plurality of fourth arc surfaces 332 .

[0028] In this embodiment, the first conductive member 3 is an integral structure. During use, the first conductive member 3 can be expanded so that its inner diameter is larger than the outer diameter of the movable body 22. After the first conductive member 3 is moved to the desired position, the external force is removed, causing the first conductive member 3 to retract and ultimately fit over the outer surface of the movable body 22. Alternatively, another assembly method can be employed, such as initially flattening the first conductive member 3 and then directly attaching the first conductive member 3 along the outer periphery of the movable body 22. After assembly using this assembly method, a gap will remain in the support ring 31, allowing for later disassembly. Of course, the support ring 31 can also be closed at the end to eliminate this gap.

[0029] like Figure 8 As shown, Figure 8 The figure shows the first conductive member 3 in a disassembled state. In another embodiment, the first conductive member 3 can be split axially, so that the first conductive member 3 is divided into two parts. During assembly, the two parts only need to be placed on the outer surface of the movable body 22. To facilitate installation and removal, a clamping block and a clamping slot structure can be provided to connect the two parts.

[0030] like Figure 9 As shown, Figure 9It is another split state diagram of the first conducting member 3. In another embodiment, the first conducting member 3 can be cut along the radial direction so that the first conducting member 3 is divided into two parts. During assembly, only these two parts need to be sleeved on the outer surface of the movable body 22. For the convenience of installation and disassembly, the connection between the two can be achieved by setting the structure of the clamping block and the clamping groove.

[0031] In this embodiment, the first conducting member 3, the second conducting member 4 and the third conducting member 5 are all made of materials with high conductivity and high yield strength, such as the same as the existing crown springs, torsion springs and other materials.

[0032] In summary, the current conduction between the carrier 1 and the floating member 2 is realized through the first conducting member 3. The external pin is inserted into the third receiving groove 211 and the fourth receiving groove 212, and the current conduction is realized through the second conducting member 4 and the third conducting member 5. The combination of the first conducting member 3, the second conducting member 4 and the third conducting member 5 can greatly increase the current conduction path, thereby improving the current-carrying capacity of the floating connection terminal, and at the same time, it is also beneficial to improve the current conduction efficiency.
