[0002] The present invention relates to a floating connector, particularly to a floating connector that stabilizes high frequency signal transmission. Description of the state of the art

[0003] It is well known that in the design of floating connectors, most of the terminals arranged in the floating area of ​​the connector housing are suspended without contact with the housing. When the floating connector is used to transmit high-frequency signals, this can easily cause transmission vibrations throughout the transmission segment between the two circuit boards, significantly reducing the stability of high-frequency signal transmission. To solve this problem, floating connectors typically increase the width of the terminals in the transmission segment, thereby increasing the cross-sectional area of ​​the terminals to modify the probability of transmission vibrations.However, given that the terminals must be mounted and secured to the connector housing, the width of the section where the terminals are mounted on the floating housing must be reduced. This, in turn, increases the capacitance in this area, leading to unstable signal transmission. This poses a significant problem for high-frequency signal transmission.

[0021] The following are based on the Fig. 3 to 6 further details of the second housing 30 are explained.

[0022] Fig. 3 shows a perspective view of the second housing 30. Fig. 4 shows a plan view of the second housing 30. Fig. 5 shows a front view of the second housing 30. Fig. 6 shows a bottom view of the second housing 30. The second housing 30 has a bottom surface 32 disposed opposite the fitting portion 31, and the bottom surface 32 is located mainly in a plane perpendicular to the first direction, thereby enabling the mounting of the high-frequency insulating member 50 along the first direction.

These fixing members 33 are disposed at both ends of the bottom surface 32, and each fixing member 33 has a hook structure with elastic arms. In this embodiment, the number of fixing members 33 is two, and the fixing members are arranged in pairs. However, the invention is not limited to this; the number of fixing members 33 can be increased or decreased as needed.After the high-frequency insulating member 50 is mounted on the bottom surface 32 of the second housing 30, these fixing members 33 can prevent the high-frequency insulating member 50 from shifting in the longitudinal direction (in the first direction) relative to the second housing 30.

[0023] The second housing 30 further includes a plurality of guide members 34 protruding from the bottom surface 32 for guiding the mounting position of the high-frequency insulating member 50. These guide members 34 are arranged at both ends of the bottom surface 32, and each guide member 34 has a sliding structure. In the present embodiment, the number of guide members 34 is two, and the guide members are arranged in pairs. However, the invention is not limited to this; the number of guide members 34 can be increased or decreased as needed. During the mounting process of the high-frequency insulating member 50 to the second housing 30, these guide members 34 serve as guide means.After the high-frequency insulation element 50 is mounted on the second housing 30, these guide elements 34 can prevent the high-frequency insulation element 50 from shifting laterally (in the plane perpendicular to the first direction) relative to the second housing 30. Each guide element 34 has a guide element chamfer located at the end of the guide element 34 facing away from the bottom side 32.

[0024] The second housing 30 further includes a plurality of positioning members 35 protruding from the bottom surface 32 for positioning the mounting location of the high-frequency insulating member 50. These positioning members 35 are arranged between the fixed members 33, each positioning member 35 having a protruding columnar structure. In the present embodiment, the number of positioning members 35 is two, and the positioning members are arranged in pairs. However, the invention is not limited to this; the number of positioning members 35 can be increased or decreased as needed. During the mounting process of the high-frequency insulating member 50 to the second housing 30, these positioning members 35 serve as positioning means.After the high-frequency isolation element 50 is mounted on the second housing 30, these positioning elements 35 can prevent the high-frequency isolation element 50 from shifting laterally (in the plane perpendicular to the first direction) relative to the second housing 30. Each positioning element 35 has a positioning element chamfer located at the end of the positioning element 35 facing away from the bottom side 32.

In the present embodiment, four through-holes 36 are provided, arranged in pairs. However, the invention is not limited to this; the number of through-holes 36 may be increased or decreased as needed. After the high-frequency insulating member 50 is mounted to the second housing 30, these through-holes 36 serve as means for disassembling the high-frequency insulating member 50 by allowing tools to be passed through the through-holes 36 in the first direction to disassemble the mounted high-frequency insulating member 50.

[0026] For further explanations of the high frequency insulating element 50, please refer to Fig. 7 to 10 are referred to.

[0027] Fig. 7 shows a perspective view of the high-frequency insulating element 50. Fig. 8 shows a plan view of the high-frequency insulating element 50. Fig. 9 shows a front view of the high-frequency insulating element 50. Fig. 10 shows a bottom view of the high-frequency insulation element 50. The high-frequency insulation element 50 is mounted along the first direction on the bottom side 32 of the second housing 30. The high-frequency insulation element 50 has two long sides 51, two short sides 52, an upper surface 53, an opposite lower surface 54, and a plurality of receiving grooves 55. The long sides 51 and the short sides 52 are arranged between the upper surface 53 and the lower surface 54, with each end of the long sides 51 being connected to a different short side 52. Both the upper surface 53 and the lower surface 54 are planes extending perpendicular to the first direction, and the upper surface 53 can be adapted to the bottom side 32 of the second housing 30 along the first direction.Each long side 51 extends in the second direction and perpendicular to the upper surface 53 and the lower surface 54, while each short side 52 extends in the third direction and perpendicular to the upper surface 53 and the lower surface 54. The high-frequency isolation element 50 further includes a plurality of chamfered portions 56 disposed at the junctions of the long sides 51 and the short sides 52. During assembly of the high-frequency isolation element 50 to the second housing 30, these chamfered portions 56 can help reduce structural interactions between the second housing 30 and the high-frequency isolation element 50.

[0028] The receiving grooves 55 are arranged on the long sides 51 at predetermined intervals in the second direction. The number, position, and type of these receiving grooves 55 correspond to the number, position, and type of the contact elements 40 they are intended to receive. In the present embodiment, the number of receiving grooves 55 is 60, with the receiving grooves being arranged in pairs of 30 receiving grooves 55 each. However, the invention is not limited to this; the number of receiving grooves 55 can be adjusted according to the number of contact elements 40. Each receiving groove 55 extends in the first direction from the upper surface 53 to the lower surface 54, and each receiving groove 55 extends in the third direction toward the upper surface of the long side 51, thereby forming an opening through which the corresponding contact element 40 can be passed and received in the receiving groove 55.Each receiving groove 55 has a receiving groove chamfer 551 disposed within the receiving groove 55 and proximate the top surface 53. During assembly of the high-frequency insulating element 50 to the second housing 30, the receiving groove chamfer 551 can help reduce structural interactions between the contact elements 40 and the high-frequency insulating element 50.

[0029] The high-frequency insulating member 50 also has a plurality of guide grooves 57 arranged on the short sides 52, the number, position, and type of these guide grooves 57 corresponding to the number, position, and type of the guide elements 34 of the second housing 30. Each guide groove 57 has a sliding slot structure. In the present embodiment, the number of guide grooves 57 is two, and the guide grooves are arranged in pairs. Each guide groove 57 extends in the first direction from the upper surface 53 to the lower surface 54, and each guide groove 57 extends in the second direction toward the surface of the short side 52, forming an opening through which the guide elements 34 can pass. During assembly of the high-frequency insulating member 50 to the second housing 30, these guide grooves 57, in conjunction with the guide elements 34, serve as guide means.After the high-frequency insulation element 50 is mounted on the second housing 30, these guide grooves 57, together with the guide elements 34, can prevent the high-frequency insulation element 50 from shifting laterally (in the plane perpendicular to the first direction) relative to the second housing 30. Each guide groove 57 has a guide groove chamfer located within the guide groove 57 and near the top surface 53. During the assembly process of the high-frequency insulation element 50 on the second housing 30, the guide groove chamfer can help reduce structural interactions between the second housing 30 and the high-frequency insulation element 50.

[0030] The high-frequency insulating member 50 also includes a plurality of positioning grooves 58 arranged within the long side 51 and short side 52 regions. The number, position, and configuration of these positioning grooves 58 correspond to the number, position, and configuration of the positioning members 35 of the second housing 30. In the present embodiment, the number of positioning grooves 58 is two, and the positioning grooves are arranged in pairs. Each positioning groove 58 has a recessed structure and extends in the first direction from the upper surface 53 to the lower surface 54. During assembly of the high-frequency insulating member 50 to the second housing 30, these positioning grooves 58, in conjunction with the positioning members 35, serve as positioning means.After mounting the high-frequency insulation element 50 on the second housing 30, these positioning grooves 58, together with the positioning elements 35, can prevent the high-frequency insulation element 50 from shifting laterally (in the plane perpendicular to the first direction) relative to the second housing 30. Each positioning groove 58 has a positioning groove chamfer located within the positioning groove 58 and near the top surface 53. During the mounting process of the high-frequency insulation element 50 on the second housing 30, the positioning groove chamfer can help reduce structural interactions between the second housing 30 and the high-frequency insulation element 50.

[0031] Fig. 11 shows a perspective view of one of the contact elements 40. The contact element 40 comprises: a fixed portion 41, a first holding portion 42, a spring portion 43, a second holding portion 44, and a contact portion 45. The first holding portion 42 extends from the fixed portion 41, the spring portion 43 connects the first holding portion 42 and the second holding portion 44, and the contact portion 45 extends from the second holding portion 44. The fixed portion 41 is attached to the circuit board by soldering.

[0032] The spring portion 43 includes a first curved portion 431, a second curved portion 432, an extension portion 433, a third curved portion 434, and a fourth curved portion 435. The first holding portion 42 is connected to one end of the extension portion 433 via the first curved portion 431 and the second curved portion 432, while the second holding portion 44 is connected to the other end of the extension portion 433 via the third curved portion 434 and the fourth curved portion 435. The curvature direction of the first curved portion 431 is different from the curvature direction of the second curved portion 432. Similarly, the curvature direction of the third curved portion 434 is different from the curvature direction of the fourth curved portion 435.

[0033] Below we refer to the Fig. 12 to 14 are referred to. Fig. 12 is a perspective view showing the high-frequency insulating member 50 after receiving the plurality of contact elements 40. Fig. 13 is a front view showing the high-frequency insulating member 50 after receiving the plurality of contact elements 40. Fig. 14 is a side view showing the high-frequency insulating member 50 after receiving the plurality of contact elements 40. Since the plurality of contact elements 40 are arranged at predetermined intervals in the second direction and the receiving grooves 55 of the high-frequency insulating member 50 are also arranged at predetermined intervals in the second direction, the receiving grooves 55 can receive the contact elements 40.

[0034] Each receiving groove 55 receives a part of the corresponding contact element 40, in particular the local structure of the spring portion 43 of the contact element 40. The local structure of the spring portion 43 of the contact element 40 received in the receiving groove 55 of the high-frequency insulating element 50 is located between the second holding portion 44 and the third curved portion 434, and the local structure encloses the entire fourth curved portion 435. The local structure is adjacent to the second holding portion 44. To facilitate receiving the contact elements 40 in the receiving groove 55 of the high-frequency insulating element 50, the structural design ensures that the width of each receiving groove 55 in the second direction is greater than the width of the local structure of the contact elements 40 in the second direction.

[0035] Below we refer to the Fig. 15 to 17 are referred to. Fig. 15 shows a side cross-sectional view of the floating connector 10 according to the present invention along the second direction. Fig. 16 shows another side cross-sectional view of the floating connector 10 along the second direction. Fig.17 shows a side cross-sectional view of the floating connector 10 along the third direction. During assembly of the high-frequency insulating element 50 along the first direction to the second housing 30, the guide elements 34 of the second housing 30 gradually slide into the guide grooves 57 of the high-frequency insulating element 50, ensuring that the high-frequency insulating element 50 is guided and held in position during assembly along the first direction to the second housing 30. At the same time, the positioning elements 35 of the second housing 30 gradually engage the positioning grooves 58 of the high-frequency insulating element 50, thereby positioning the high-frequency insulating element 50 relative to the second housing 30 so that the correct assembly position is maintained.After the high-frequency insulating member 50 is mounted along the first direction on the bottom surface 32 of the second housing 30, the fixing members 33 of the second housing 30 can secure the bottom surface 54 of the high-frequency insulating member 50 to fix the high-frequency insulating member 50 relative to the second housing 30. At this time, the high-frequency insulating member 50 is substantially held between the first housing 20 and the second housing 30.

[0036] The contact elements 40 are mounted within the first housing 20 and the second housing 30. In terms of structural design, the first holding portion 42 of the contact element 40 is pressed into the first housing 20 and mounted where it is held by the first housing 20, while the second holding portion 44 of the contact element 40 is pressed into the second housing 30 and mounted where it is held by the second housing 30. Generally, the spring portion 43 of each contact element 40 is almost in a suspended state within the first housing 20. In this embodiment, during the mounting of the high-frequency insulating element 50 along the first direction to the second housing 30, the spring portion 43 of each contact element 40 gradually enters and is received in the corresponding receiving groove 55 of the high-frequency insulating element 50 near the local structure of the second holding portion 44.After the high-frequency insulating element 50 is mounted along the first direction on the second housing 30, the local structure of the spring portion 43 of each contact element 40 is completely received within the respective receiving groove 55, with the local structure generally not in contact with the walls of the receiving groove 55. Other parts of the spring portion 43, apart from this local structure, remain suspended and thus do not impair the floating function of the connector. Therefore, the arrangement of the high-frequency insulating element 50 can reduce transmission vibrations during high-frequency signal transmission and improve the stability of the high-frequency signal transmission.
