Description

[Technical Field]

[0001] The present invention relates to a floating connector, and more particularly to a floating connector that stabilizes the transmission of high frequency signals. [Background technology]

[0002] In conventional floating connector designs, most of the terminals within the floating area of ​​the connector housing are floating and do not come into contact with the housing. When using floating connectors for high-frequency signal transmission, transmission vibrations are likely to occur in the transmission area between the terminals of the two printed circuit boards. This significantly reduces the stability of high-frequency signal transmission. To solve this problem, conventional floating connectors typically increase the number of terminals in the width direction of the transmission area, increasing the cross-sectional area to suppress transmission vibrations. However, considering that the terminals must be assembled and fixed to the connector housing, the width of the area where the terminals and floating housing are assembled must be reduced. This conventional method actually increases the capacitance in that area, making signal transmission unstable. This is a major problem in high-frequency signal transmission. Summary of the Invention

[0016] A connector assembly according to an embodiment of the present invention will now be described with reference to the accompanying drawings. In each drawing, similar components or components having the same function are designated by the same reference numerals. The drawings are not drawn to scale. In the following description, the term "contact member" generally refers to a signal contact member unless otherwise specified.

[0017] The components of the floating connector 10 of the present invention will be outlined with reference to Figures 1 and 2. Figure 1 is a perspective view of the floating connector of the present invention. Figure 2 is an exploded perspective view of the floating connector 10 of the present invention. The floating connector is generally designated by the reference numeral 10. The floating connector 10 is mounted on a printed circuit board (not shown) and electrically connected to a mating connector (not shown) mounted on another printed circuit board. The floating connector 10 is specifically a socket connector, and the mating connector is specifically a plug connector.

[0018] The floating connector 10 includes a first housing 20 as a fixed housing, a second housing 30 as a movable housing, a plurality of contact members 40, a high-frequency insulating member 50 made of resin, and two ground members 60.

[0019] The second housing 30 has a mating portion 31 that mates with a mating connector in a first direction. The second housing 30 is assembled to the first housing 20 so as to be movable in a plane perpendicular to the first direction. In this invention, the first direction is defined as the Z-axis direction, the second direction as the Y-axis direction, the third direction as the X-axis direction, and the plane perpendicular to the first direction as the XY plane.

[0020] In this embodiment, the number of contact members 40 is 60, and they are arranged in pairs of 30 contact members 40. The floating connector 10 may further include a plurality of power contact members (not shown). The power contact members are arranged on both sides of each pair of contact members 40. The contact members 40 and the power contact members are made of a conductive material, such as copper or a copper alloy. However, the present invention is not limited thereto, and the number of contact members 40 and the power contact members can be increased or decreased as needed.

[0021] The second housing 30 will be further described with reference to FIGS.

[0022] FIG. 3 is a perspective view of the second housing 30. FIG. 4 is a plan view of the second housing 30. FIG. 5 is a front view of the second housing 30. FIG. 6 is a bottom view of the second housing 30. The second housing 30 includes a bottom 32. The bottom 32 is located opposite the mating portion 31. The bottom 32 is located on a plane that is primarily perpendicular to the first direction, allowing the high-frequency insulating member 50 to be assembled along the first direction. The second housing 30 includes a plurality of fixing members 33. The fixing members 33 protrude from the bottom 32 and can fix the high-frequency insulating member 50. The fixing members 33 are located at both ends of the bottom 32. Each fixing member 33 has a locking structure with an elastic arm. In this embodiment, there are two fixing members 33, which are installed in pairs. However, the present invention is not limited to this, and the number of fixing members 33 can be increased or decreased as needed. After the high-frequency insulating member 50 is assembled to the bottom 32 of the second housing 30, the fixing member 33 can prevent the high-frequency insulating member 50 from being displaced in the vertical direction (first direction) relative to the second housing 30.

[0023] The second housing 30 further includes a plurality of guide members 34. The guide members 34 protrude from the bottom 32 and guide the high-frequency insulating member 50 to the assembly position. The guide members 34 are located at both ends of the bottom 32. Each guide member 34 is a slider. In this embodiment, there are two guide members 34, which are installed in pairs. However, the present invention is not limited to this, and the number of guide members 34 can be increased or decreased as needed. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the guide members 34 function as a guide means. After the high-frequency insulating member 50 is assembled to the second housing 30, the guide members 34 prevent the high-frequency insulating member 50 from displacing laterally (in a plane perpendicular to the first direction) relative to the second housing 30. Each guide member 34 has a guide member chamfer. The guide member chamfer is located at the end of the guide member 34 away from the bottom 32. In the process of assembling the high-frequency insulating member 50 to the second housing 30, the chamfered guide member can reduce interference between the guide member 34 and the high-frequency insulating member 50.

[0024] The second housing 30 further includes a plurality of positioning members 35. The positioning members 35 protrude from the bottom 32 and position the high-frequency insulating member 50 in the assembly position. The positioning members 35 are located between the fixing members 33. Each positioning member 35 is a protruding post. In this embodiment, there are two positioning members 35, which are installed in pairs. However, the present invention is not limited to this, and the number of positioning members 35 can be increased or decreased as needed. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the positioning members 35 function as a positioning means. After the high-frequency insulating member 50 is assembled to the second housing 30, the positioning members 35 prevent the high-frequency insulating member 50 from displacing laterally (in a plane perpendicular to the first direction) relative to the second housing 30. Each positioning member 35 has a positioning member chamfer. The positioning member chamfer is located at the end of the positioning member 35 away from the bottom 32. In the process of assembling the high-frequency insulating member 50 to the second housing 30, the interference between the positioning member 35 and the high-frequency insulating member 50 can be reduced by chamfering the positioning member.

[0025] The second housing 30 further includes a plurality of through holes 36. Each through hole 36 extends from the fitting portion 31 to the bottom portion 32 in the first direction. In this embodiment, the number of through holes 36 is four, and they are arranged in pairs. However, the present invention is not limited to this, and the number of through holes 36 can be increased or decreased as needed. After the high-frequency insulating member 50 is assembled to the second housing 30, the through holes 36 function as holes for removing the high-frequency insulating member 50. This allows a user to use a tool to pass through the through holes 36 along the first direction to remove the assembled high-frequency insulating member 50. When the high-frequency insulating member 50 is assembled to the second housing 30, the positioning member 35 prevents the high-frequency insulating member 50 from being displaced laterally (in a plane perpendicular to the first direction) relative to the second housing 30.

[0026] The high-frequency insulating member 50 will be further described with reference to FIGS.

[0027] FIG. 7 is a perspective view of the high-frequency insulating member 50. FIG. 8 is a plan view of the high-frequency insulating member 50. FIG. 9 is a front view of the high-frequency insulating member 50. FIG. 10 is a bottom view of the high-frequency insulating member 50. The high-frequency insulating member 50 is assembled to the bottom 32 of the second housing 30 along the first direction. The high-frequency insulating member 50 includes two long side surfaces 51, two short side surfaces 52, opposing upper and lower surfaces 53 and 54, and a plurality of receiving grooves 55. The long side surfaces 51 and the short side surfaces 52 are disposed between the upper surface 53 and the lower surface 54. Both ends of each long side surface 51 are connected to the short side surfaces 52, respectively. The upper surface 53 and the lower surface 54 are both planes perpendicular to the first direction. The upper surface 53 is assembled to the bottom 32 of the second housing 30 along the first direction. Each long side surface 51 extends in the second direction and is a plane perpendicular to the upper surface 53 and the lower surface 54. Each short side surface 52 extends in the third direction and is a plane perpendicular to the top surface 53 and the bottom surface 54. The high-frequency insulating member 50 further includes a plurality of chamfered portions 56. The chamfered portions 56 are located at the connection portions of the long side surfaces 51 and the short side surfaces 52. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the chamfered portions 56 can reduce interference between the second housing 30 and the high-frequency insulating member 50.

[0028] The receiving grooves 55 are disposed on the long side surface 51. The receiving grooves 55 are arranged at predetermined intervals in the second direction. The number, position, and shape of the receiving grooves 55 correspond to the number, position, and shape of the contact members 40, thereby accommodating the contact members 40. In this embodiment, there are 60 receiving grooves 55, and 30 receiving grooves 55 are arranged in pairs. However, the present invention is not limited to this, and the number of receiving grooves 55 can be adjusted according to the number of contact members 40. Each receiving groove 55 penetrates from the upper surface 53 to the lower surface 54 in the first direction. Each receiving groove 55 forms an opening on the surface of the long side surface 51 in the third direction. Thus, the contact members 40 pass through the opening and are accommodated in the receiving groove 55. Each receiving groove 55 has a receiving groove chamfer 551. The receiving groove chamfer 551 is located close to the upper surface 53 of the receiving groove 55. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the accommodating groove chamfer 551 can reduce interference between the contact member 40 and the high-frequency insulating member 50.

[0029] The high-frequency insulating member 50 further includes a plurality of guide grooves 57. The guide grooves 57 are located on the short side surfaces 52. The number, position, and shape of the guide grooves 57 correspond to the number, position, and shape of the guide members 34 of the second housing 30. Each guide groove 57 is a slide groove. In this embodiment, there are two guide grooves 57, which are located in pairs. Each guide groove 57 penetrates from the upper surface 53 to the lower surface 54 in the first direction. Each guide groove 57 forms an opening on the surface of the short side surfaces 52 in the second direction through which the guide members 34 pass. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the guide grooves 57 and the guide members 34 function as guide means. After assembling the high-frequency insulating member 50 to the second housing 30, the guide grooves 57 and the guide members 34 prevent the high-frequency insulating member 50 from displacing laterally (in a plane perpendicular to the first direction) relative to the second housing 30. Each guide groove 57 has a guide groove chamfer located adjacent to the upper surface 53 of the guide groove 57. The guide groove chamfer can reduce interference between the second housing 30 and the high-frequency insulating member 50 during assembly of the high-frequency insulating member 50 to the second housing 30.

[0030] The high-frequency insulating member 50 further includes a plurality of positioning grooves 58. The positioning grooves 58 are located within the enclosed area of ​​the long side surface 51 and the short side surface 52. The number, position, and shape of the positioning grooves 58 correspond to the number, position, and shape of the positioning members 35 of the second housing 30. In this embodiment, there are two positioning grooves 58, which are arranged in pairs. Each positioning groove 58 is a concave groove. Each positioning groove 58 penetrates from the upper surface 53 to the lower surface 54 in the first direction. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the positioning grooves 58 and the positioning members 35 function as positioning means. After assembling the high-frequency insulating member 50 to the second housing 30, the positioning grooves 58 and the positioning members 35 prevent the high-frequency insulating member 50 from being displaced laterally (in a plane perpendicular to the first direction) relative to the second housing 30. Each positioning groove 58 has a positioning groove chamfer. The positioning groove chamfer is located close to the upper surface 53 of the positioning groove 58. During the process of assembling the high-frequency insulating member 50 to the second housing 30, the positioning groove chamfer can reduce interference between the second housing 30 and the high-frequency insulating member 50.

[0031] 11 is a perspective view showing the contact member 40. The contact member 40 includes 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 is continuous with the fixed portion 41. The spring portion 43 connects the first holding portion 42 and the second holding portion 44. The contact portion 45 is continuous with the second holding portion 44. The fixed portion 41 is fixed to a printed circuit board by soldering.

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

[0033] The following description will be given with reference to Figs. 12 to 14. Fig. 12 is a perspective view showing a state in which a plurality of contact members are housed in a high-frequency insulating member. Fig. 13 is a front view showing a state in which a plurality of contact members are housed in a high-frequency insulating member. Fig. 14 is a side view showing a state in which a plurality of contact members are housed in a high-frequency insulating member. The plurality of contact members 40 are arranged at predetermined intervals in the second direction. The housing grooves 55 of the high-frequency insulating member 50 are also arranged at predetermined intervals in the second direction. This allows the housing grooves 55 to house the contact members 40.

[0034] Each accommodating groove 55 accommodates a part of the contact member 40, in particular a local structure of the spring portion 43 of the contact member 40. The local structure of the spring portion 43 of the contact member 40 accommodated in the accommodating groove 55 of the high-frequency insulator 50 is located between the second holding portion 44 and the third curved portion 434. The local structure includes the entire fourth curved portion 435. The local structure is adjacent to the second holding portion 44. To facilitate accommodating the contact member 40 in the accommodating groove 55 of the high-frequency insulator 50, the structural design has the width of each accommodating groove 55 in the second direction greater than the width of the local structure of the contact member 40 in the second direction.

[0035] 15 to 17 will be described. FIG. 15 is a cross-sectional side view of the floating connector of the present invention taken along the second direction. FIG. 16 is another cross-sectional side view of the floating connector of the present invention taken along the second direction. FIG. 17 is a cross-sectional side view of the floating connector of the present invention taken along the third direction. During the process of assembling the high-frequency insulating member 50 to the second housing 30 along the first direction, the guide member 34 of the second housing 30 gradually slides into the guide groove 57 of the high-frequency insulating member 50. As a result, the high-frequency insulating member 50 is assembled to the second housing 30 while being guided along the first direction. In addition, the positioning member 35 of the second housing 30 gradually fits into the positioning groove 58 of the high-frequency insulating member 50. As a result, the high-frequency insulating member 50 is accurately positioned relative to the second housing 30. After assembling the high-frequency insulating member 50 to the bottom 32 of the second housing 30 along the first direction, the lower surface 54 of the high-frequency insulating member 50 is engaged with the fixing member 33 of the second housing 30, thereby fixing the high-frequency insulating member 50 to the second housing 30. In this state, the high-frequency insulating member 50 is generally held between the first housing 20 and the second housing 30.

[0036] The contact members 40 are assembled within the first housing 20 and the second housing 30. In terms of structural design, the first retaining portion 42 of the contact members 40 is press-fit into the first housing 20 and is held by the first housing 20. The second retaining portion 44 of the contact members 40 is press-fit into the second housing 30 and is held by the second housing 30. Generally, the spring portion 43 of each contact member 40 is floating within the first housing 20. In this embodiment, during the assembly of the high-frequency insulating member 50 to the second housing 30 in the first direction, the local structure of the spring portion 43 of each contact member 40 adjacent to the second retaining portion 44 enters and is accommodated within the accommodating groove 55 of the high-frequency insulating member 50. After the high-frequency insulating member 50 is assembled to the second housing 30 in the first direction, the local structure of the spring portion 43 of each contact member 40 is completely accommodated within the accommodating groove 55. The local structure generally does not contact the groove wall of the accommodating groove 55. Since the spring portion 43 is in a floating state except for the local structure, the requirements for a floating connector are still met. Therefore, the installation of the high-frequency insulating member 50 can reduce transmission vibration during high-frequency signal transmission and improve the stability of high-frequency signal transmission.

[0037] Although the present invention has been described with reference to preferred embodiments, those skilled in the art may make various modifications as appropriate within the scope of the present invention. Therefore, the present invention is not limited to the above-described embodiments, but is subject to the scope of the utility model registration claims.
