Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and in particular to a high-speed floating connector assembly. Background Technology

[0002] Floating connectors are precision electronic components designed for transmitting high-speed signals in systems demanding high reliability and performance. Their core feature is the "floating" structure, which allows for minute axial and radial positional misalignments between the connector's plug and socket, automatically compensating for alignment errors caused by manufacturing tolerances, thermal expansion and contraction, or vibration and shock. This self-correcting capability effectively avoids installation stress, ensuring long-term connection stability. Furthermore, through careful impedance matching, shielding design, and differential signal transmission schemes, they can support high-speed data rates from several Gbps to tens of Gbps, perfectly combining high-reliability mechanical characteristics with excellent electrical performance. Therefore, high-speed floating connectors are widely used in communication base stations, data center servers, industrial equipment, and automotive electronics—fields with stringent requirements for signal integrity and connection durability.

[0003] To meet the growing demand for miniaturization and high-density integration of electronic products and to effectively save PCB space, small-pitch height floating connector assemblies are designed and manufactured. Small pitch refers to the extremely small center distance between connector terminals, typically less than 1 mm.

[0004] Existing high-speed floating connector assemblies include mating male and female connectors. The male connector, as a core component, mainly consists of a plastic housing and conductive terminals. After the conductive terminals are inserted into the housing, to ensure a proper fit between the conductive terminals and the plastic housing, a mating cavity is typically created on the plastic housing along the insertion direction of the conductor terminals. However, to enhance the fit between the conductive terminals and the female connector, as well as with the plastic housing, the conductive terminals are bent to conform to the sidewalls of the plastic housing, forming a bent portion. The bent ends of the conductive terminals are then used to facilitate soldering to the circuit board. While this method is feasible, it requires bending the already formed conductive terminals, which severely impacts their lifespan. Alternatively, a mating cavity can be directly created on the plastic housing to allow the entire conductive terminal to pass through along the insertion direction, but this affects the bonding strength between the conductive terminals and the plastic housing, leading to unstable installation of the conductive terminals.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Please see Figures 1 to 2 The high-speed floating connector assembly of this utility model includes a male connector and a female connector that are mated together.

[0020] Please see Figures 3 to 10 The small-pitch high-speed floating male connector includes a first conductive terminal 1 and a plastic housing 2 having a first insertion cavity 23, wherein the first conductive terminal 1 is inserted into the first insertion cavity 23.

[0021] Please see Figures 3 to 6 as well as Figure 10The first conductive terminal 1 is made of a conductive metal such as copper and is used for transmitting electrical signals. In this embodiment, the first conductive terminal 1 includes a bent portion 1a inserted into the first insertion cavity 23 along the insertion direction and a first welding portion 1b bent from the bent portion 1a. The bent portion 1a is used to combine with the plastic housing 2. The plastic housing 2 supports, positions and protects the bent portion 1a. At the same time, the bent portion 1a is inserted into the external female connector along with the plastic housing 2. When the female connector is inserted into this invention, the bent portion 1a contacts the female connector to realize the conduction of electrical signals.

[0022] The bending portion 1a includes a first arm segment 11 arranged along the insertion direction, a second arm segment 12 extending parallel to the width direction of the plastic shell 2 after bending from the first arm segment 11, a third arm segment 13 extending along the insertion direction towards the same side as the first arm segment 11 after bending from the second arm segment 12, and a fourth arm segment 14 connected to the first arm segment 11 and extending along the insertion direction away from the second arm segment 12. All arm segments are integrally connected and can be formed by stamping or molding, thus making the bending portion 1a U-shaped. To improve the bonding force and firmness between the bending portion 1a and the plastic shell 2, barbs 15 are protruding on both sides of the width of the fourth arm segment 14. The width of the barbs 15 is slightly larger than the width of the cavity in the plastic shell 2 into which the fourth arm segment 14 passes, so that the fourth arm segment 14 presses against the plastic shell 2 after being extruded into it, achieving a tight fit between the fourth arm segment 14 and the plastic shell 2. The first welding part 1b extends parallel to the second arm segment 12 toward the side away from the first arm segment 11 after being bent from the end of the fourth arm segment 14 away from the third arm segment 13. After the first conductive terminal 1 is inserted into the plastic housing 2, the first welding part 1b is supported on the plastic housing 2 and can restrict the first conductive terminal 1 from being inserted further in the insertion direction. At the same time, the plastic housing 2 exposes the first welding part 1b outside the plastic housing 2, which facilitates soldering with the circuit board.

[0023] Please see Figures 3 to 9The plastic housing 2 is formed by plastic injection molding and is rectangular in shape with length, width, and height. The height direction of the plastic housing 2 is defined as the insertion direction. A first insertion cavity 23 is formed along the insertion direction so that the first conductive terminal 1 is mounted on the plastic housing 2 along the insertion direction. The plastic housing 2 includes a pull-out portion 21 into which a bending portion 1a is inserted along the insertion direction, and a connecting portion 22 detachably connected to the pull-out portion 21 along the insertion direction and limiting the first welding portion 1b. The bending portion 1a of the first conductive terminal 1 is inserted into the pull-out portion 21, while the first welding portion 1b is supported and limited on the connecting portion 22. This allows the first conductive terminal 1 to be connected to the connecting portion 22 along the insertion direction with the pull-out portion 21, without being affected by the first welding portion 1b, ensuring the integrity of the first conductive terminal 1 and eliminating the need for secondary bending that would affect its service life. The insertion part 21 and the connecting part 22 together form a first insertion cavity 23, so that the first conductive terminal 1 can be installed on the split plastic housing 2; the insertion part 21 is used to insert into the female connector.

[0024] The insertion / removal part 21 includes a mating part 21a and a head 21b integrally connected to the mating part 21a. The mating part 21a and the head 21b are sequentially connected along the insertion direction. The mating part 21a is used for mating with the female connector, and the head 21b is used for detachable connection with the connecting part 22. Both the mating part 21a and the head 21b are generally rectangular. Relative to the head 21b, the side of the mating part 21a facing away from the head 21b along the insertion direction is defined as the mating surface 211. In order to increase the bonding force between the mating part 21a and the female connector, a mating cavity 212 is recessed on the mating part 21a to avoid the corresponding internal structure of the female connector so that the corresponding structure of the female connector can be mated therein. The mating cavity 212 makes the mating surface 211 hollow inside the mating part 21a, thereby improving the bonding force between the female connector and the insertion / removal part 21. The insertion cavity 212 is rectangular, resulting in the insertion portion 21a having two first side walls 213a relatively distributed on both sides of the insertion cavity 212 and two second side walls 213b relatively distributed on the other two sides of the insertion cavity 212. The first side walls 213a and the second side walls 213b together form a square frame structure. The two first side walls 213a are parallel and spaced apart along the width direction of the insertion portion 21a, and the two second side walls 213b are parallel and spaced apart along the length direction of the insertion portion 21a.

[0025] In this embodiment, mating cavities 231 are recessed along the inner and outer sides of the two first side walls 213a. Specifically, the mating cavity 231 includes a first cavity 2311 formed on the outer wall of the insertion portion 21a along the insertion direction, a second cavity 2312 recessed in the mating surface along the insertion direction and communicating with the first cavity 2311, and a third cavity 2313 formed in the wall of the insertion cavity 212 along the insertion direction and communicating with the second cavity 2312, thereby making the mating cavity 231 generally U-shaped. The first cavity 2311 is open outward in the width direction, the second cavity 2312 penetrates the mating surface along the insertion direction, and the third cavity 2313 is open inward in the width direction. In this embodiment, multiple mating cavities 231 are evenly spaced along the length direction, and the distance between any two adjacent mating cavities 231 is within 1mm. In particular, in this embodiment, the distance between two adjacent mating cavities 231 can be 0.4mm, achieving an ultra-small distance. The first conductive terminal 1 is matched with it, and after assembly, the distance between two adjacent first conductive terminals 1 is about 0.4mm, achieving high-density integration and miniaturization.

[0026] The head 21b extends integrally from the interlocking portion 21a along the insertion direction towards the side opposite to the interlocking surface 211. On the head 21b, the opposite sides corresponding to the two first side walls 213a are configured as inner walls 214, and on the head 21b, the opposite sides corresponding to the two second side walls 213b are configured as end faces 217. The first cavity segment 2311 connects to the inner wall surface 214 and is flush with the inner wall surface 214 on its inward side, so that both sides of the interlocking portion 21a protrude slightly from the inner wall surface 214 along the width direction. A locking block 215 protrudes from each end face 217. The locking block 215 is a right-angled triangle (i.e., a triangular prism). One right-angled surface of the locking block 215 forms a mating surface along the insertion direction away from the interlocking portion 21a, and the inclined surface of the locking block 215 forms a guide surface facing away from the end face 217, so that the locking block 215 can be used to abut against the connecting portion 22. To make it easier for the card block 215 to be inserted into the connecting part 22, a reducing groove 216 is recessed on the side of the head 21b facing away from the insertion part 21a along the insertion direction, close to the card block 215, so that the position where the card block 215 is located is thinned by the reducing groove 216. At the same time, the reducing groove 216 provides a certain deformation space for the position where the card block 215 is located.

[0027] The connecting part 22 has a cuboid structure. A mating cavity 221 is provided on the connecting part 22 along the insertion direction, which is adapted to the shape and size of the head 21b so that the head 21b can be inserted into the mating cavity 221 along the insertion direction. Therefore, the mating cavity 221 is usually cuboid in shape and has two wide cavity surfaces 2211 and two narrow cavity surfaces 2212 that are relatively distributed. The two wide cavity surfaces 2211 correspond to the two inner circumferential surfaces 214 and are distributed on both sides of the width of the mating cavity 221, and the two narrow cavity surfaces 2212 correspond to the two end surfaces 217 and are distributed on both sides of the length of the mating cavity 221. The wide cavity surface 2211 is recessed with an inwardly facing peripheral groove 222 that extends through the connecting part 22 in the insertion direction. The peripheral groove 222 is rectangular in shape, and the groove surface of each peripheral groove 222 is configured as a peripheral surface. The peripheral surface is aligned with the first cavity section 2311 of each first fastening cavity section 232. When the head 21b is inserted into the mating cavity 221 and connected to the connecting part 22, the wide cavity surface 2211 is close to the periphery of the inner circumferential surface 214, so that the inner circumferential surface 214 and the peripheral surface of the peripheral groove 222 together form the first fastening cavity section 232. The distance between the two wide cavity surfaces 2211 should be adapted to the width of the mating part 21a so that it can pass through. Therefore, after the head 21b is connected to the connecting part 22, the wide cavity surface 2211 will be slightly spaced from the inner circumferential surface 214. This allows the first conductive terminal 1, after being installed on the insertion part 21 along the insertion direction, to pass through the mating cavity 221 along the insertion direction, so that the plastic housing 2 does not need to be provided with an additional cavity for the first welding part 1b to pass through, thus ensuring the stability between the plastic housing 2 and the first conductive terminal 1.

[0028] To improve the stability between the head 21b and the connecting part 22, anti-misalignment strips 2213 (anti-misalignment refers to preventing rotation and error) extending along the insertion direction are provided on both wide cavity surfaces 2211. The anti-misalignment strips 2213 are arranged to protrude along the width direction, and the two anti-misalignment strips 2213 are diagonally distributed, with one located at one end of the wide cavity surface 2211 along the length direction and the other located at the other end of the other wide cavity surface 2211 along the direction. Anti-misalignment grooves 218 are recessed on the two inner circumferential surfaces 214 at the positions corresponding to the positions of the two anti-misalignment strips 2213, in which the anti-misalignment strips 2213 are inserted along the insertion direction. The anti-misalignment grooves 218 are open outward and extend along the insertion direction through the side of the head 21b away from the connecting part 21a.

[0029] To restrict the head 21b after the connecting part 22 and the head 21b are installed, anti-retraction grooves 2214 are provided on both narrow cavity surfaces 2212, which are internally connected to the mating cavity 221. When the head 21b is inserted into the mating cavity 221, the anti-retraction grooves 2214 are aligned with the locking block 215 and allow the locking block 215 to be engaged in them. The anti-retraction grooves 2214 have a limiting surface that blocks the mating surface along the insertion direction away from the interlocking part 21a when the locking block 215 is engaged in it.

[0030] To increase the connection strength between the connector 22 and the circuit board, two solder tabs 24 are inserted into the connector 22. Each of the connector 22 has slots 223 extending through it along the insertion direction on both sides near the two end faces 217. Each slot 223 includes a wide section and a narrow section narrower than the wide section but connected to it. The solder tab 24 passes through the narrow section and has a limiting foot 241 at its end that is inserted into the wide section. The end of the solder tab 24 away from the limiting foot 241 is bent and extends longitudinally. The side of the connector 22 facing away from the insertion part 21a along the insertion direction is defined as the soldering surface. The narrow section extends through the soldering surface, and the bent end of the solder tab 24 is located outside the soldering surface for soldering to the circuit board, thereby holding the circuit board in place. In order to make it easier for the locking block 215 to be inserted into the anti-retraction groove 2214, both anti-retraction grooves 2214 are directly opposite the slots 223 and the two slots 223 are respectively connected to the anti-retraction grooves 2214, so that the narrow cavity surface 2212 has a certain deformation capability by thinning the connecting part 22 where the narrow cavity surface 2212 is located. On the welding surface, welding cavity segments 233 are recessed on both sides corresponding to the outer surface along the width. The welding cavity segments 233 penetrate the welding surface along the insertion direction and the inward end is connected to the outer groove 222. Therefore, in this utility model, the first insertion cavity 23 is composed of a mating cavity segment 231 formed on the insertion part 21 for the bending part 1a to be inserted in the insertion direction, a first fastening cavity segment 232 connected to the mating cavity segment 231 along the insertion direction and surrounded by the insertion part 21 and the connecting part 22, and a welding cavity segment 233 connected to the first fastening cavity segment 232 and for the first welding part 1b to be confined therein.

[0031] Please see Figures 11 to 19 The female connector includes a fixed housing 3, a compensation housing 4 surrounding the outer wall of the fixed housing 3, a floating housing 5 movably disposed within the fixed housing 3, and a second conductive terminal 6 inserted into the fixed housing 3 and the floating housing 5.

[0032] Please see Figures 11 to 15The fixed housing 3 is shaped according to the application scenario. In this embodiment, the fixed housing 3 is a cuboid structure formed by plastic injection molding, thus having length, width, and height, and the length, width, and height of the fixed housing 3 are consistent with those of the plastic housing 1. A floating cavity 31 with openings on both sides along the height direction is formed on the fixed housing 3, and the floating housing 5 is installed in the floating cavity 31 along the height direction. One side of the fixed housing 3 along the height direction is defined as a connecting surface 33. A second insertion cavity 32 is also formed on the fixed housing 3, which extends along the height direction through the connecting surface 33. The second conductive terminal 6 is inserted into the second insertion cavity 32. Similarly, the height direction of the fixed housing 3 is defined as the insertion direction, and the second conductive terminal 6 is inserted into the second insertion cavity 32 along the insertion direction. It should be noted that the aforementioned width and length directions refer to the width and length directions of the fixed housing 3.

[0033] To limit the floating housing 5 from moving indefinitely in the insertion direction, facilitate the arrangement of the second insertion cavity 32 and the installation of the second conductive terminal 6, and also to save material, two inner layer portions 34 are integrally connected to both sides of the fixed housing 3 along the width direction. The length of the two inner layer portions 34 is arranged along the length direction of the fixed housing 3 and integrally connected to the inner wall of the fixed housing 3. The inner layer portions 34 are spaced apart from the inner wall of the fixed housing 3 to form a spacer cavity 341. The side of the two inner layer portions 34 closest to the connecting surface 33 along the insertion direction is shorter than the connecting surface 33 and recessed relative to the connecting surface 33, so that a clearance cavity 342 communicating with the spacer cavity 341 is separated between the inner layer portion 34 and the connecting surface 33. The side of the fixed housing 3 facing away from the connecting surface 33 along the insertion direction is defined as the first pair of insertion surfaces 35. The side of the two inner layers 34 away from the connecting surface 33 along the insertion direction is shorter than the first pair of insertion surfaces 35. The two inner layers 34 extend along the width direction away from the connecting surface 33 and are integrally connected to the fixed housing 3, forming a stepped surface 36 on the side close to the first pair of insertion surfaces 35. The floating cavity 31 is formed in a T-shape by the fixed housing 3 and the inner layers 34 including the stepped surface 36. The second insertion cavities 32 are formed in two symmetrical groups, respectively located on the two inner layers 34 and the two side walls along the width direction of the fixed housing 3. Each group has several second insertion cavities 32, evenly spaced, and the number and position of the second insertion cavities 32 are the same as those of the first insertion cavities 23. Each second insertion cavity 32 is connected to the spacer cavity 341 and the clearance cavity 342. The spacer cavity 341 not only reduces the material used in the fixed housing 3, but also reduces the processing difficulty of the second insertion cavity 32. At the same time, the formation of the spacer cavity 341 can also improve the heat dissipation effect for the second conductive terminal 6 inserted therein and the second insertion cavity 32. The distance between any two adjacent second insertion cavities 32 is within 1 mm. In particular, in this embodiment, the distance between two adjacent second insertion cavities 32 can be 0.4 mm, achieving an ultra-small distance. The second conductive terminal 6 is matched with it, and after assembly, the distance between two adjacent second conductive terminals 6 is about 0.4 mm, achieving high-density integration and miniaturization. The second insertion cavity 32 includes a fourth cavity segment 321 formed on the side wall of the fixed housing 3, a fifth cavity segment 322 formed on the spacer cavity 341, and a sixth cavity segment 323 formed on the inner layer 34. The fourth cavity segment 321 is recessed in the side wall of the fixed housing 3 and extends inwardly through the spacer cavity 341 in the width direction. The fifth cavity segment 322 is recessed in the side cavity surface of the spacer cavity 341 near the first pair of insertion surfaces 35 and communicates with the fourth cavity segment 321. The sixth cavity segment 323 is recessed in the inner layer 34 on the side near the connecting surface 33 in the insertion direction and communicates with the floating cavity 31 and the spacer cavity 341 in the width direction. The sixth cavity segment 323 also communicates with the clearance cavity 342 in the insertion direction.

[0034] Please see Figure 14 and Figure 16 The compensating shell 4 is a rectangular frame structure with a width adapted to the height of the fixed shell 3 and surrounding the outer wall of the fixed shell 3. The compensating shell 4 is made of metal such as steel to strengthen the overall strength of the fixed shell 3 and prevent damage from external impacts. To enhance the strength between the compensating shell 4 and the fixed shell 3, triangular buckles 371 are protruding from any two opposite outer walls of the fixed shell 3. The buckles 371 are wider near the connecting surface 33 and gradually narrower near the first pair of insertion surfaces 35, becoming flush with the outer wall of the fixed shell 3, thus forming a guiding bevel on the buckles 371 to facilitate the installation of the compensating shell 4. Slots or holes 41 are provided on the compensating shell 4 corresponding to the positions of each buckle 371. After the compensating shell 4 is fitted onto the fixed shell 3, the buckles 371 engage with the slots or holes 41, thereby securing the compensating shell 4 to the fixed shell 3.

[0035] To further enhance the connection strength between the compensation shell 4 and the fixed shell 3, slots or holes 41 are provided on one of the opposite sides of the compensation shell 4. On the other opposite sides of the compensation shell 4, a recessed edge 421 is provided on one side of the corresponding connecting surface 33 along its width direction. An extension piece 422 and a bent foot 423 extending away from the compensation shell 4 after being vertically bent from the extension piece 422 are integrally formed in the recessed edge 421. A fourth barb 374 is formed on the extension piece 422, which is stamped along the thickness direction. After stamping, a window is formed on the extension piece 422. The fourth barb 374 is integrally connected to the side of the window near the bent foot 423. The other opposite side of the fourth barb 374 is suspended. The fourth barb 374 is inclined outward from the window along the length direction from the suspended side. The buckle 371 on the fixed housing 3 corresponds to the slot or hole 41, and the fixed housing 3 has a protrusion 372 corresponding to the extension piece 422. The protrusion 372 has a through hole 373 for the extension piece 422 to pass through and a buckle groove that connects to the through hole 373 and allows the fourth barb 374 to be engaged therein. The bent foot 423 is formed by the extension piece 422 extending uniformly as a whole. After the extension piece 422 passes through the through hole 373, the part of it that extends out of the through hole 373 is bent to form the bent foot 423. The concave edge 421 and the bent foot 423 are used to restrict the movement of the compensation housing 4 along the insertion direction. When the extension piece 422 passes through the through hole 373, the fourth barb 374 is squeezed and deformed towards the window until the fourth barb 374 aligns with the buckle groove and is engaged therein, thereby further improving the connection between the extension piece 422 and the protrusion 372.

[0036] Please see Figures 11 to 13 and Figure 18The floating shell 5, corresponding to the formation of the floating cavity 31, has an integrally connected wide section 51 and narrow sections 52 on both sides that are narrower than the wide section 51. Both the wide section 51 and the narrow section 52 are approximately cuboid in shape, and their length, width, and height are aligned with the length, width, and height of the fixed shell 3. The overall height of the floating shell 5 is less than the depth of the floating cavity 31. The width and length of the wide section 51 are both less than the width and length of the portion of the floating cavity 31 enclosed by the inner wall of the fixed shell 3, and the width and length of the narrow section 52 are both less than the width and length of the portion of the floating cavity 31 enclosed by the inner layer 34. This allows the floating shell 5, after being installed within the floating cavity 31, to be spaced apart from the floating cavity 31, thus forming a floating space. In order to reduce interference when the floating shell 5 moves in the floating space, inclined surfaces 511 are formed on both sides of the wide section 51 that are wider than the narrow section 52 in the width direction, extending obliquely to the outer wall of the narrow section 52. After the floating shell 5 is installed in the floating cavity 31, the inclined surfaces 511 are spaced apart and directly opposite the inner side of the step surface 36 and the inner side of the inner layer 34, thereby increasing the range of movement of the floating shell 5 and reducing interference.

[0037] The floating shell 5 has a plug-in cavity 53 and a third plug-in cavity 54. The plug-in part 21 is plugged into the plug-in cavity 53 along the insertion direction, and a part of the second conductive terminal 6 is plugged into the third plug-in cavity 54. The side of the wide section 51 facing away from the narrow section 52 along the insertion direction is defined as the second pair of plug-in surfaces 551, and the side of the narrow section 52 facing away from the wide section 51 along the insertion direction is defined as the second mating surface 552. The plug-in cavity 53 is recessed from the second pair of plug-in surfaces 551 and is symmetrically arranged in two sets corresponding to the two sets of second plug-in cavities 32. The length of the two sets of plug-in cavities 53 is arranged along the length direction of the floating shell 5, and each end of the two sets of plug-in cavities 53 is connected to the end of the other set, so that the two sets of plug-in cavities 53 are in a cuboid frame structure, so as to facilitate the plugging and unplugging of the first side wall 213a and the second side wall 213b of the plug-in part 21a and improve the bonding force. The insertion cavity 53 extends through the second pair of insertion surfaces 551 along the insertion direction and has a U-shaped inner wall, so that the floating housing 5 is located inside the two sets of insertion cavities 53, forming a central part 56 located in the middle of the entire floating housing 5 and used for insertion into the insertion cavity 212.

[0038] The third insertion cavity 54 is formed on the narrow section 52 and the wide section 51 and is also arranged in two groups. Each group has a number of third insertion cavities 54 that are the same in number and position as the second insertion cavities 32, and the spacing between adjacent third insertion cavities 54 is the same as the spacing between the second insertion cavities 32. The third insertion cavity 54 extends from the outer wall of the floating housing 5 inward to the outer wall of the center portion 56 along the width direction. The third insertion cavity 54 is located on the portion of the floating housing 5 that is relative to the periphery of the insertion cavity 53 and penetrates the outer wall of the floating housing 5 and the insertion cavity 53 along the width direction. The third insertion cavity 54 penetrates the second mating surface 552 along the insertion direction, so that the second conductive terminal 6 can be inserted into the third insertion cavity 54 along the insertion direction and extend out of the third insertion cavity 54 along the width direction to mate with the second insertion cavity 32. Specifically, the side of the third insertion cavity 54 that is close to the second pair of insertion surfaces 551 along the insertion direction is defined as the top cavity surface, and the side of the third insertion cavity 54 that is far away from the insertion / removal cavity 53 along the width direction is defined as the side cavity surface.

[0039] Please see Figure 17The second conductive terminal 6 includes a second soldering part 61 for soldering to a circuit board, a first fastening part 62 for insertion into a second insertion cavity 32, a second elastic compensation part 63 that movably passes through a floating space and a third insertion cavity 54, and a second fastening part 64 for insertion into a third insertion cavity 54, wherein the second fastening part 64 has a compensation structure 65 that extends into the insertion cavity 53 to abut against the first arm segment 11. Corresponding to the structure of the second conductive terminal 6, the second insertion cavity 32 includes a first movable cavity segment and a second fastening cavity segment 324 that is wider than the first movable cavity segment. The first fastening part 62 is inserted into the second fastening cavity segment 324 along the insertion direction and is abutted against the second fastening cavity segment 324 by a second barb 661. The first movable cavity is composed of a fourth cavity 321, a fifth cavity 322, and a sixth cavity 323. A second welding cavity 325 is recessed on the connecting surface 33 and located outside the spacer cavity 341, allowing the second welding part 61 to pass through. This enables the second welding part 61 to bend from the first fastening part 62, extend out of the fixing housing 3 along the width direction from the second welding cavity 325, and be soldered to the circuit board. A first fastening cavity 324 is formed along the length direction of the fourth cavity 321, fitting against the inner wall of the fixing housing 3 and recessed within the inner wall of the fourth cavity 321. Therefore, the width of the first fastening cavity 324 is greater than the width of the first movable cavity. The first fastening cavity 324 extends through the connecting surface 33 along the insertion direction. The first fastening portion 62 has second barbs 661 protruding on both sides. The first fastening portion 62 of the second conductive terminal 6 is inserted into the first fastening cavity 324 from the side of the connecting surface 33 along the insertion direction. The second barbs 661 abut against the inner wall of the first fastening cavity 324 to limit the second conductive terminal 6. The second fastening portion 64 is inserted into the third fastening cavity 541 along the insertion direction and abuts against the third fastening cavity 541 by a third barb 662. The second elastic compensation portion 63 includes a first segment 631 extending along the inner wall of the first movable cavity and a second segment 632 extending from the first segment 631 in the width direction toward the third insertion cavity 54. The first segment 631 is formed by bending the first fastening portion 62, extending inward in the width direction, bending again, extending toward the connecting surface 33 in the insertion direction, and then bending again to extend inward in the width direction. The second segment 632 is formed by bending the first segment 631 and extending inward in the width direction.

[0040] To correspond to the structure of the second conductive terminal 6, the third insertion cavity 54 includes a third fastening cavity section 541 that is opened along the insertion direction and disposed outside the insertion / removal cavity 53 in the width direction, and a second movable cavity section that is narrower than the third fastening cavity section 541 and surrounds the third fastening cavity section 541. The second elastic compensation portion 63 passes through the second movable cavity section. The second fastening portion 64 includes a fastening section 641 that extends along the insertion direction after being bent from the second section 632. A compensation structure 65 is formed on the end of the fastening section 641 away from the second section 632. The compensation structure 65 includes a guide portion 65a that extends into the insertion / removal cavity 53 and is elastically deformable, and a first elastic compensation portion that is bent from the guide portion 65a to elastically compensate for the guide portion 65a after it is compressed. The guide portion 65a is formed by an inward arching from the middle of the extension portion of the fastening section 641 along the insertion direction, so that the guide portion 65a includes a first elastic arm 651, a third bending section 656, and a second elastic arm 652 that are V-shaped in general. When the third bending section 656 is inserted into the insertion cavity 53, it can be connected to the male connector by resisting the first arm section 11 through the guide portion 65a, thereby improving the reliability between the male connector and the male connector. The first elastic compensation section includes a first bent section 654 connected to the second elastic arm 652, a third elastic arm 653 connected to the first bent section 654 and inclined in a V shape relative to the second elastic arm 652, and a second bent section 655 connected to the third elastic arm 653 and bent toward the first elastic arm 651. The first bent section 654 and / or the second bent section 655 provide compensation to the guide contact 65a by deforming against the third insertion cavity 54 when the guide contact 65a is held. The first bending section 654 is used to press against the floating housing 5 and support the guide contact 65a through deformation elasticity when the guide contact 65a is pressed. The second bending section 655 is used to support the first bending section 654 through deformation elasticity when the guide contact 65a is pressed. The second elastic arm 652, the first bending section 654 and the third elastic arm 653 are V-shaped. The first bending section 654 bends in the insertion direction toward the side away from the second elastic compensation part 63, and the second bending section 655 bends in the width direction toward the side of the first fastening part 62.

[0041] In use, after aligning the first fastening part 62 with the first fastening cavity 324 and the second fastening part 64 with the third fastening cavity 541 from the side of the connecting surface 33, the second conductive terminal 6 can be pushed along the insertion direction to insert the second conductive terminal 6 into the second insertion cavity 32 and the third insertion cavity 54. The compensation structure 65 is located between the top cavity surface and the side cavity surface. After the second welding part 61 is located in the second welding cavity 325, the second elastic compensation part 63 is located in the first movable cavity, the floating space and the second movable cavity. The second barb 661 and the third barb 662 prevent the second conductive terminal 6 from falling off and abut against the male connector from both sides, ensuring the stability and firmness between the male connector and the second conductive terminal 6.

[0042] One embodiment of the high-speed floating connector assembly of this utility model operates as follows: After separating the insertion / removal part 21 and the connecting part 22, the bent portion 1a of the first conductive terminal 1 is inserted into the mating cavity 231, that is, the first arm segment 11 is inserted into the first cavity 2311, the second arm segment 12 is inserted into the second cavity 2312, and the third arm segment 13 is inserted into the third cavity 2313, wherein the fourth arm segment 14 is attached to the inner circumferential surface 214, and the first welding part 1b extends outward; after each of the first arm segments 11 is inserted into the mating cavity 2311, the second arm segment 12 is inserted into the second cavity 2312, and the third arm segment 13 is inserted into the third cavity 2313, wherein the fourth arm segment 14 is attached to the inner circumferential surface 214, and the first welding part 1b extends outward; After all conductive terminals 1 are inserted into the mating cavity 231, the insertion and removal part 21 passes through the mating cavity 221 from the welding surface side of the connecting part 22 along the insertion direction until the locking block 215 is inserted into the slot, and the outer surface and the inner surface 214 form the first fastening cavity 232. The barbs 15 on the fourth arm 14 abut against the outer surface, and the first welding part 1b is located in the welding cavity 233, thereby completing the installation of the plastic shell 2 and the first conductive terminal 1. After that, the welding pull tab 24 and the first welding part 1b are welded to the circuit board. The compensation shell 4 is installed on the fixed shell 3, and the second conductive terminal 6 is installed in the second insertion cavity 32, so that the second welding part 61 abuts against the second welding cavity section 325. The second fastening part 64 and the second elastic compensation part 63 of the second conductive terminal 6 are both located in the floating cavity 31. After the insertion part side of the floating shell 5 faces the floating cavity 31 and the second fastening part 64 is aligned with each of the third fastening cavity sections 541, the floating shell 5 is moved along the insertion direction so that the second fastening part 64 is installed in the third insertion cavity 54. Then, a circuit board is soldered on the fixed shell 3, and the second welding part 61 is soldered to the circuit board. Then, the connection can be achieved by the mating of the male connector and the female connector.

[0043] Compared with the prior art, the high-speed floating connector assembly of this utility model controls the movement of the floating housing 5 within a limited range, ensuring the reliability of the first and second conductive terminals 6 and improving the service life of the first and second conductive terminals 6. The limited space restricts the range of the floating housing 5 in the insertion direction and width direction, while the length direction is mutually restricted by the second insertion cavity 32 and the third insertion cavity 54.
