[0038] Embodiment 1

[0039] like Figure 1-Figure 8 As shown, Figure 1 It is a schematic diagram of the three-dimensional structure of the floating connector; Figure 2 is a cross-sectional schematic diagram of a floating connector; Figure 3 It is a partial structural schematic diagram of a floating connector; Figure 4 It is a partial structural front view of the floating connector; Figure 5 It is a partial structural cross-sectional view of a floating connector; Figure 6 is a schematic diagram of the three-dimensional structure of the first contact body 3; Figure 7 is a schematic diagram of the three-dimensional structure of the second contact body 23;

[0040] Figure 8 The floating connector of the present application comprises a carrier 1, a connecting body 2 and a first contact body 3. The connecting body 2 penetrates the carrier 1 and can move relative to the carrier 1. The first contact body 3 is disposed in the carrier 1 and abuts against the connecting body 2.

[0041] Review Figure 1 and Figure 2 The carrier 1 is provided with a through hole 11 and a first receiving groove 12. The through hole 11 is opened along the longitudinal direction of the carrier 1. The connecting body 2 is located in the through hole 11 and the connecting body 2 can move inside the through hole 11. The first receiving groove 12 is opened along the wall surface of the through hole 11. For example, the cross section of the through hole 11 is circular, and the cross section of the first receiving groove 12 is also circular; at the same time, the first receiving groove 12 is connected to the through hole 11; the first receiving groove 12 has a bottom wall 121 and a side wall 122, and the first contact body 3 is located on the surface of the side wall 122 of the first receiving groove 12. In this embodiment, only the surface of one side wall 122 is provided with the first contact body 3.

[0042] The connecting body 2 includes a connecting cylinder 21 and a connecting block 22. The connecting cylinder 21 is located in the through hole 11, and both ends of the connecting cylinder 21 extend outside the through hole 11 respectively. The connecting block 22 is arranged around the outer surface of the connecting cylinder 21, and the connecting block 22 is movably arranged in the first receiving groove 12, and the first contact body 3 abuts against the connecting block 22. Further, there is a spacing L between the outer wall surface 221 of the connecting block 22 and the bottom wall 121 of the first receiving groove 12, and the spacing L is the space where the connecting block 22 can move. In other words, the connecting cylinder 21 can move 360° around the center of the through hole 11 in the through hole 11 to adapt to deviations at different positions. Furthermore, the connector 2 further includes a second contact body 23 and a fixing sleeve 24. The second contact body 23 is arranged inside the connector tube 21 (i.e., in the hollow position). At the same time, a supporting platform 211 is provided at one end of the connector tube 21. One end of the second contact body 23 is located on the supporting platform 211, and the other end of the second contact body 23 is located at the end of the connector tube 21 away from the supporting platform 211. The fixing sleeve 24 is sleeved on the end of the connector tube 21 away from the supporting platform 211 and the end of the second contact body 23 away from the supporting platform 211, and the second contact body 23 is fixed in the connector tube 21 by the fixing sleeve 24. It should also be noted that the second contact body 23 is also a hollow structure, which facilitates the external pin to be inserted into the hollow structure to achieve abutment with the second contact body 23.

[0043] Please review Figure 7 and Figure 8 The second contact body 23 includes a first contact area 231, a plurality of connecting strips 232 and a second contact area 233. The fixing sleeve 24 is sleeved on one 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 to each other. The plurality of connecting strips 232 are spaced apart and distributed between the first contact area 231 and the second contact area 233. The second contact area 233 is located on the supporting platform 211.

[0044] Among them, the end area of ​​the connecting strip 232 close to the first contact area 231 is provided with a first protrusion 2321, the first protrusion 2321 protrudes outward, and the first protrusion 2321 abuts against the wall surface of the connecting tube 21. It should be noted that the cross-sections of the first contact area 231 and the second contact area 233 in this embodiment are circular, so the inside of the circle is set as the inside, and the outside of the circle is set as the outside. Further, the end of the connecting strip 232 close to the second contact area 233 is provided with a second protrusion 2322, similarly, the second protrusion 2322 also protrudes outward, and the second protrusion 2322 also abuts against the inner wall surface of the connecting tube 21; when the plug pin is inserted, the plug pin gives the first contact part an outward expansion force, causing the first contact part to deform, and synchronously, it will drive multiple first protrusions 2321 to expand outward. When the plug pin is inserted to the end, the second protrusion 2322 is also expanded outward.

[0045] In specific applications, there is an angle 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 between the first contact area 231 and the second contact area 233 at inclined intervals.

[0046] Please review Figure 3-Figure 6The first contact body 3 includes a support ring 31 and a plurality of guide bars 32. The support ring 31 is located in the first receiving groove 12. The plurality of guide bars 32 are spaced apart in the support ring 31. The connection block 22 abuts against the plurality of guide bars 32. Further, the plurality of guide bars 32 are arranged obliquely in the same direction, that is, the guide bars 32 and the support ring 31 are not arranged vertically. There is an angle between the tangents of the guide bars 32 and the support ring 31. The angle is an obtuse angle. By means of oblique distribution, the length of the entire guide bar 32 can be effectively increased, which saves effort when assembling the connection block 22. Furthermore, the guide strip 32 also has a first arc surface 321 and a second arc surface 322. The first arc surface 321 is arranged in a direction close to the connecting block 22, and the second arc surface 322 is arranged in the opposite direction of the first arc surface 321, that is, the second arc surface 322 extends in a direction close to the side wall 122 of the first accommodating groove 12; when in use, the first arc surface 321 abuts against the connecting block 22, and the second arc surface 322 abuts against the side wall 122 of the first accommodating groove 12. Preferably, the first contact body 3 also includes a limit strip 33, which is arranged in the support ring 31, and the limit strip 33 is arranged in the same manner as the guide strip 32; in specific application, one side of the limit strip 33 is located on the side wall 122 of the first accommodating groove 12, and the distance between the first arc surface 321 and the limit strip 33 is S, and the distance between the second arc surface 322 and the side wall 122 of the first accommodating groove 12 is D, wherein D<S, so that when the connecting block 22 applies a longitudinal force, the travel limit of the guide strip 32 under the force is S, and after the guide strip 32 reaches this limit, the connecting block 22 abuts against the upper surface of the limit strip 33, and the guide strip 32 will not continue to move downward, thereby avoiding the connecting block 22 applying excessive force on the guide strip 32 and causing damage to the guide strip 32. In addition, since the D value is smaller than the S value, the second arc surface 322 first abuts against the side wall 122 of the first receiving groove 12 during the downward pressing of the guide bar 32, and then the guide bar 32 will be further pressed downward. During this process, the second arc surface 322 will increase the pressure on the side wall 122, increase the positive force on the side wall 122, and thus help reduce the temperature rise generated during subsequent use. Preferably, the outer surface of the support ring 31 is also provided with a tooth pattern 311, and the tooth pattern 311 contacts the bottom wall 121 of the first receiving groove. Through the provision of the tooth pattern 311, the contact area between the outer surface of the support ring 31 and the bottom wall 121 of the first receiving groove 12 is reduced, the resistance of the support ring 31 assembly is reduced, and the efficiency of the assembly and disassembly of the support ring 31 is improved.

[0047] 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.
