[0040] This application provides a stable conductive terminal, including a conductive terminal body, a first interdigitated sheet and a second interdigitated sheet respectively formed on the conductive terminal body, the conductive terminal body forming an interdigitated forming area, the first interdigitated sheet and the second interdigitated sheet both protruding from the inner wall of the interdigitated forming area, the first interdigitated sheet and the second interdigitated sheet being parallel to each other, and an interdigitated gap being formed between the first interdigitated sheet and the second interdigitated sheet; the conductive terminal body forming a plurality of floating deformation portions along the extending direction, the conductive terminal body sequentially opening a plurality of first discharge holes along the extending direction, each of the floating deformation portions having at least one first discharge hole.

[0041] The aforementioned stable conductive terminal, due to the interdigitated molding area formed on the conductive terminal body, with the first and second interdigitated pieces protruding from the inner wall of the interdigitated molding area, the first and second interdigitated pieces being parallel to each other, and an interdigitated gap formed between the first and second interdigitated pieces, creates a capacitance area in the interdigitated molding area of ​​the stable conductive terminal, improving the capacitance of the stable conductive terminal in the interdigitated molding area and giving the stable conductive terminal better inductive impedance. Furthermore, due to the multiple floating deformation parts formed along the extension direction of the conductive terminal body, and the multiple first blanking holes sequentially opened along the extension direction of the conductive terminal body, with each floating deformation part having at least one first blanking hole, the conductive terminal body has better floating performance and inductive impedance. At the same time, the stable conductive terminal has a better bandpass filtering effect for high-frequency signal transmission, that is, the bandpass filtering effect for high-frequency signal transmission is more obvious, avoiding the problem of severe crosstalk between adjacent conductive terminals during signal transmission in floating connectors.

[0042] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0043] like Figures 1 to 4 As shown, a floating connector assembly 10 in one embodiment includes a first connector 100 and a second connector 200. The first connector 100 and the second connector 200 are mated together to achieve a floating connection between them. In this embodiment, the first connector 100 includes a stable conductive terminal 110. Specifically, the first connector 100 also includes a first connector base 120 and a floating socket 130. The first connector base 120 has a communicating floating groove 122 and a first slot 124. The floating socket 130 is movably disposed within the floating groove 122, allowing the floating socket 130 to move relative to the first connector base 120.

[0044] like Figures 1 to 4As shown, the floating socket 130 further comprises a second slot 132 and a first pair of slot openings 134 that are connected to each other. One end of the stable conductive terminal 110 is inserted into the first slot 124, and the other end of the stable conductive terminal 110 is inserted into the second slot 132. One end of the stable conductive terminal 110 is located in the first pair of slot openings 134. The second connector 200 includes a second connector 210 and a male terminal 220. The second connector 210 forms a second pair of slot openings 212, and the second pair of slot openings 212 are provided with protruding tongues 2122. The male terminal 220 is disposed on the second connector 210 and protrudes from the side wall of the protruding tongues 2122. The first connector 120 is inserted into the second pair of slot openings 212, and the protruding tongues 2122 are inserted into the first pair of slot openings 134. The male terminal 220 elastically abuts against the stable conductive terminal 110, so that the first connector 100 is electrically connected to the second connector 200 when it is plugged into the second connector 200.

[0045] Furthermore, the number of male terminals 220 and the number of stable conductive terminals 110 are both at least four, and the number of first slots 124 and second slots 132 are both at least four. All four first slots 124 are connected to the floating slot 122, and all four second slots 132 are connected to the first pair of slot openings 134. Each stable conductive terminal 110 has both ends inserted into the corresponding first slot 124 and the corresponding second slot 132, respectively. Each stable conductive terminal 110 elastically abuts against the corresponding male terminal 220, thus electrically connecting each stable conductive terminal 110 to the corresponding male terminal 220. Specifically, the four stable conductive terminals are a first stable conductive terminal, a second stable conductive terminal, a third stable conductive terminal, and a fourth stable conductive terminal, arranged side-by-side in sequence. Among them, the first stable conductive terminal and the fourth stable conductive terminal are both grounding terminals, which together form a grounding terminal group; the second stable conductive terminal and the third stable conductive terminal are both differential signal terminals, which together form a differential signal terminal group.

[0046] like Figure 2 , Figure 4 , Figure 5 and Figure 5aAs shown, in one embodiment, the stable conductive terminal 110 includes a conductive terminal body 110a and a first interdigitated piece 110b and a second interdigitated piece 110c respectively formed on the conductive terminal body 110a. The conductive terminal body 110a has an interdigitated forming area 102, and the first interdigitated piece 110b and the second interdigitated piece 110c both protrude from the inner wall of the interdigitated forming area 102. The first interdigitated piece 110b and the second interdigitated piece 110c are parallel to each other, and an interdigitated gap 104 is formed between the first interdigitated piece 110b and the second interdigitated piece 110c to form an interlocking area in the interdigitated forming area 102. The conductive terminal body 110a has a plurality of floating deformation portions 1103 formed along the extending direction, and the conductive terminal body 110a has a plurality of first discharge holes 106 sequentially opened along the extending direction, and each of the floating deformation portions 1103 has at least one first discharge hole 106.

[0047] The aforementioned stable conductive terminal 110, because the conductive terminal body 110a has an interdigitated molding area 102, and the first interdigitated piece 110b and the second interdigitated piece 110c are both protruding from the inner wall of the interdigitated molding area 102, the first interdigitated piece 110b and the second interdigitated piece 110c are parallel to each other, and an interdigitated gap 104 is formed between the first interdigitated piece 110b and the second interdigitated piece 110c, so that the stable conductive terminal 110 forms a capacitance area in the interdigitated molding area 102, thereby improving the capacitance of the stable conductive terminal 110 in the interdigitated molding area 102, and making the stable conductive terminal have It has good inductive impedance, and because the conductive terminal body has multiple floating deformation parts formed along the extension direction, and multiple first blanking holes are sequentially opened along the extension direction of the conductive terminal body, each floating deformation part has at least one first blanking hole, the conductive terminal body has good floating performance and inductive impedance, and at the same time, the stable conductive terminal has a good bandpass filtering effect for high frequency signal transmission, that is, the bandpass filtering effect for high frequency signal transmission is more obvious, avoiding the problem of severe crosstalk between adjacent conductive terminals during signal transmission in floating connectors.

[0048] like Figure 5 or Figure 5aAs shown, for the aforementioned stable conductive terminal 110, the first interdigitated finger 110b and the second interdigitated finger 110c are parallel to each other, and an interdigitated gap 104 is formed between the first interdigitated finger 110b and the second interdigitated finger 110c. This creates a longitudinal interdigitated structure in the interdigitated forming area 102 of the stable conductive terminal 110, which not only improves the capacitance of the stable conductive terminal 110 in the interdigitated forming area 102 and gives the stable conductive terminal better inductive impedance, but also, since the conductive terminal body 110a has a first blanking hole 106, the stable conductive terminal 110 has a better bandpass filtering effect for high-frequency signal transmission. That is, the bandpass filtering effect for high-frequency signal transmission is more obvious, avoiding the problem of severe crosstalk between adjacent conductive terminals during signal transmission in floating connectors.

[0049] Furthermore, see also Figure 5 The conductive terminal body 110a includes a welding and fixing section 1102, a bending section 1104, and a snap-fit ​​section 1106, which are connected sequentially. For example... Figure 5 and Figure 14 As shown, the bent section 1104 is further shaped like an N or an S. In one embodiment, an interdigitated forming area 102 is formed between the bent section 1104 and the welded fixing section 1102.

[0050] Figure 6 This is the equivalent circuit diagram of the longitudinal interdigitated structure. The welding fixing section 1102 and the snap-fit ​​section 1106 can be respectively equivalent to the feed lines on both sides of the longitudinal interdigitated structure, where L... f1 L f2 The inductances of the two feed lines are respectively, with the inductance corresponding to the soldered fixed section 1102 being L. f1 The inductor corresponding to segment 1106 is L. f2 C t Capacitance of the terminal line to ground; C 11 This refers to the capacitance to ground of the first interdigitated plate 110b, i.e., the capacitance to ground of the left interdigitated plate; C 22 This is the capacitance to ground of the second interdigitated plate 110c, i.e., the capacitance to ground of the right interdigitated plate. R is the resistance of the interdigitated plate, L is the inductance of the interdigitated plate, and C... 12 This refers to the interdigital capacitor with interdigitated contacts. Where C... t Can be used with C respectively 11 and C 22 The process is merged. Assuming the stable conductive terminal 110 is made of a lossless material, R can be neglected, and the following can be obtained: Figure 7 The simplified equivalent circuit diagram is shown.

[0051] Based on the simplified equivalent circuit, it can be seen that the vertical interdigital structure is a bandpass model. The C in the equivalent circuit...12 It is equal to the interdigital capacitance value of the interdigital capacitor of the cross-fin.

[0052] like Figure 5 and Figure 6 As shown, under the condition of a finite thickness dielectric substrate, and the substrate thickness is much larger than the interdigital width and interdigital gap 104. Figure 6 As shown, in this embodiment, the interdigitation width d is the width of the interdigitated piece. In one embodiment, when the interdigitation width is equal to the gap, for C... 12 The calculation formula is as follows:

[0053]

[0054] Where n is the number of interdigitations; It is the length of the interdigitated fingers, in mm; It is the dielectric constant of the dielectric substrate;

[0055] like Figure 4 As shown, in one embodiment, the dielectric plate is a plate holder for mounting floating terminal assemblies. In this embodiment, the dielectric plate is a first connector 120 or a floating socket 130.

[0056] In one embodiment, when the interdigitation width and the gap are not equal, for C 12 The calculation formula is as follows:

[0057]

[0058] Where G is a constant coefficient and W is the cross-finger width.

[0059] From the two formulas above, it can be seen that the interdigital capacitance C 12 The interdigital capacitance C increases with the length of the interdigital fingers. 12 It decreases in proportion to the interdigital gap 104. For example... Figure 5 and Figure 6 As shown, the interdigitation length is either the length e of the first interdigitation piece 110b or the length f of the second interdigitation piece 110c. In this embodiment, the length e of the first interdigitation piece 110b is equal to the length f of the second interdigitation piece 110c, and both are... .

[0060] The formula for calculating the linear inductance generated during the straight-line transmission of a signal is as follows:

[0061] ;

[0062] ; ;

[0063] in, denoted by , where is the line length in μm; W is the line width; t is the metal thickness (i.e., terminal thickness); and ℎ is the dielectric substrate thickness. From the above formula, it can be seen that the linear inductance... It decreases as the line width W increases, and decreases as the line length increases. It increases as it increases.

[0064] Similarly, the formula for calculating linear inductance described above also applies to inductors with longitudinal interdigitated structures. When calculating inductors for longitudinal interdigitated structures, Let W be the interdigitation length and W be the interdigitation width. Similarly, it can be concluded that the inductance of the longitudinal interdigitation structure decreases as the interdigitation width increases and increases as the interdigitation length increases. However, for floating terminal assemblies with a longitudinal interdigitation structure, the inductance of the longitudinal interdigitation structure, i.e., the interdigitation inductance, is very small and can be ignored.

[0065] like Figure 2 and Figure 5 As shown, for the stable conductive terminal 110, the conductive terminal body 110a has a high inductive impedance. Without the interdigitated structure and the first blanking hole 106, the equivalent circuit model of the conductive terminal is as follows: Figure 8 As shown, the corresponding simplified equivalent circuit diagram is as follows: Figure 9 As shown, the corresponding peak impedance is as follows Figure 10 The peak value of the solid line in the impedance curve diagram shown; under the condition of setting the interdigitated structure, that is, forming an interdigitated forming area 102 between the bending section 1104 and the welding fixing section 1102, the first interdigitated piece 110b and the second interdigitated piece 110c are both protruding from the inner wall of the interdigitated forming area 102, the first interdigitated piece 110b and the second interdigitated piece 110c are parallel to each other, and an interdigitated gap 104 is formed between the first interdigitated piece 110b and the second interdigitated piece 110c, so that the stable conductive terminal 110 forms a capacitance area in the interdigitated forming area 102. The simplified equivalent circuit diagram of the equivalent circuit model is as follows. Figure 11 As shown, the corresponding peak impedance is as follows Figure 10 As shown by the peak value of the dashed line in the impedance curve diagram, it can be seen that the addition of interdigitated plates on the conductive terminal body 110a, namely the addition of the first interdigitated plate 110b and the second interdigitated plate 110c, improves the capacitance of the stable conductive terminal 110 in the interdigitated forming region 102, giving the stable conductive terminal better inductive impedance. This allows the inductive impedance of the stable conductive terminal to be better adjusted to the preset value. The signal crosstalk diagram of adjacent stable conductive terminals 110 is shown below. Figure 12 The star-shaped curve shown.

[0066] Furthermore, the conductive terminal body 110a is provided with a first discharge hole. In this embodiment, the conductive terminal body 110a has multiple first discharge holes 106, that is, the number of first discharge holes 106 is multiple, including two or more. A simplified equivalent circuit diagram of its equivalent circuit model is shown below. Figure 13 As shown, the signal crosstalk diagram of adjacent stable conductive terminals 110 at this time is as follows. Figure 12 The solid curve shown illustrates that, based on the crosstalk diagram of adjacent differential signals and the addition of interdigital capacitors, multiple first blanking holes 106 are provided in the conductive terminal body 110a. This allows the stable conductive terminal 110 to have a better bandpass filtering effect for high-frequency signal transmission. Specifically, the first blanking holes in the conductive terminal body 110a significantly improve the bandpass filtering effect for high-frequency signal transmission, shifting the resonant frequency of crosstalk towards higher frequencies. This improves the signal transmission bandwidth and avoids the severe crosstalk problem between adjacent conductive terminals in the floating connector assembly 10 during signal transmission. It can be understood that the number of first blanking holes 106 can be one, two, three, four, or more. Figure 15 As shown, the number of the first blanking hole 106 is one. Figure 5 or Figure 14 As shown, there are four first discharge holes 106.

[0067] like Figure 5 and Figure 8 As shown, in one embodiment, the conductive terminal body 110a is bent, and the bent section 1104 includes multiple floating deformation portions 1103 and multiple straight structures 1105. The multiple floating deformation portions 1103 and multiple straight structures are spaced apart, with one straight structure for every two adjacent floating deformation portions 1103 and one floating deformation portion 1103 for every two adjacent straight structures. This allows the conductive terminal body 110a to not only have better floating properties, but also, compared to traditional conductive terminals, to form more straight structures. Thus, within the predetermined space of the welding fixing section 1102 and the snap-fit ​​section 1106, the conductive terminal body 110a has better linear inductance, resulting in better inductive impedance. In this embodiment, the conductive terminal body 110a is shaped like a "Z," giving it better inductive impedance. Furthermore, the bending directions of the multiple floating deformation portions 1103 are arranged in opposite directions, making the structure of the conductive terminal body 110a more compact, while also giving the bent section 1104 more straight structures, thereby giving the bent section 1104 better inductive impedance. It can be understood that in other embodiments, two adjacent floating deformation portions 1103 are not limited to having only one straight structure, that is, two adjacent floating deformation portions 1103 do not have a straight structure.

[0068] like Figure 5As shown, further, the length of the first interdigitated piece 110b is equal to the length of the second interdigitated piece 110c, forming a relatively long interlocking area between the first interdigitated piece 110b and the second interdigitated piece 110c. Of course, in other embodiments, such as... Figure 5a As shown, the length of the first interdigitated finger 110b may not be equal to the length of the second interdigitated finger 110c. For example, the length of the first interdigitated finger 110b is less than the length of the second interdigitated finger 110c.

[0069] like Figure 4 As shown, further, the welding fixing segment 1102 is inserted into the first retaining groove 124, so that the welding fixing segment 1102 is fixedly connected to the first connecting seat 120. In other embodiments, the first connecting seat 120 also forms a retaining groove communicating with the first retaining groove 124, such as... Figure 5a As shown, a fixed end 1102a is formed at the connection between the welding fixing section 1102 and the bending section 1104. The fixed end 1102a is inserted into the retaining groove, so that both ends of the welding fixing section 1102 are respectively inserted into the first retaining groove 124 and the retaining groove, thereby making the welding fixing section 1102 more firmly fixed to the first connecting seat 120. Furthermore, a retaining relief groove 1102b is formed on the other side of the part where the first interdigitated piece 110b is formed on the bending section 1104, to avoid interference when the fixed end 1102a is inserted into the retaining groove, thereby making the fixed end 1102a reliably inserted into the retaining groove, while reducing the space occupied by the bending section 1104 in the floating direction, making the stable conductive terminal 110 more compact.

[0070] like Figure 5 and Figure 5a As shown, in one embodiment, a plurality of first blanking holes 106 are spaced apart along the signal transmission direction of the conductive terminal body 110a. This means the conductive terminal body 110a has a plurality of first blanking holes 106 spaced apart along the signal transmission direction, resulting in better bandpass filtering for high-frequency signal transmission. This significantly improves the bandpass filtering effect for high-frequency signals, avoiding severe crosstalk between adjacent conductive terminals during signal transmission in the floating connector assembly 10. In other embodiments, the plurality of first blanking holes 106 are not limited to being spaced apart along the signal transmission direction of the conductive terminal body 110a. For example, the distance between two adjacent first blanking holes 106 along the signal transmission direction of the conductive terminal body 110a may be unequal.

[0071] like Figure 5 , Figure 14 , Figure 15 and Figure 16 As shown, in one embodiment, the interdigitated forming region 102 is formed on at least one side or in the middle of the conductive terminal body 110a. Figure 16As shown, in this embodiment, the interdigitated forming area 102 is formed on one side of the conductive terminal body 110a. In other embodiments, the interdigitated forming area 102 is not limited to being formed on one side of the conductive terminal body 110a. For example, interdigitated forming areas 102 are formed on both sides of the conductive terminal body 110a, and each side of the conductive terminal body 110a has a first interdigitated piece 110b and a second interdigitated piece 110c arranged in a relatively staggered manner. Further, the number of first interdigitated pieces 110b and the number of second interdigitated pieces 110c are not limited to one. Figure 5 As shown, for example, the number of the first interdigitated plates 110b and the number of the second interdigitated plates 110c are both two. Figure 15 As shown, the number of first interdigitated plates 110b and the number of second interdigitated plates 110c are not limited to being equal. For example, the number of first interdigitated plates 110b may be greater than or less than the number of second interdigitated plates 110c.

[0072] like Figure 14 As shown, in other embodiments, the interdigitated forming region 102 is not limited to being formed on one or both sides of the conductive terminal body 110a. For example... Figure 15 As shown, for example, the interdigitated forming area 102 can also be formed at the middle position of the conductive terminal body 110a. Specifically, the interdigitated forming area 102 is disposed on the inner peripheral wall of one of the first blanking holes 106, so that the first interdigitated piece 110b and the second interdigitated piece 110c both protrude from the inner peripheral wall of one of the first blanking holes 106.

[0073] like Figure 14 As shown, in one embodiment, each first discharge hole 106 is a curved strip-shaped groove, making each first discharge hole 106 easy to process and shape, while also giving each first discharge hole 106 good capacity. Figure 15 As shown, in other embodiments, each first discharge hole 106 is not limited to a curved strip-shaped groove. For example, each first discharge hole 106 is a straight strip-shaped groove, a rectangular groove, an oblong groove, or other grooves.

[0074] Furthermore, each floating deformation portion 1103 has at least one first discharge hole 106, giving each floating deformation portion 1103 better elasticity, thereby giving the bending section 1104 better elasticity, improving the floating performance of the conductive terminal body 110a, and simultaneously giving the conductive terminal body 110a better bandpass filtering effect for high-frequency signal transmission. In this embodiment, each floating deformation portion 1103 has one first discharge hole 106, and the first discharge hole 106 is opened along the extension direction of the center line of the floating deformation portion 1103.

[0075] like Figure 5 and Figure 14As shown, further, at least one first blanking hole 106 is opened at both ends of the bending section 1104, that is, at least one first blanking hole 106 is opened at the position of the bending section adjacent to the welding fixing section 1102 and the snap-fit ​​section 1106 respectively, so that the conductive terminal body 110a has a better bandpass filtering effect for high frequency signal transmission.

[0076] like Figure 5 and Figure 14 As shown, in one embodiment, the center line of each first drop hole 106 coincides with the center line of the conductive terminal body 110a, so that the stable conductive terminal 110 has better capacitance, thereby better improving the crosstalk of adjacent signal transmission, and at the same time improving the structural strength of the stable conductive terminal 110.

[0077] like Figure 5 and Figure 14 As shown, in one embodiment, the lateral width of each first discharge hole 106 along the direction perpendicular to the center line of the first discharge hole 106 is uniform everywhere, so that the capacitive difference of the first discharge hole 106 of the stable conductive terminal 110 along the signal transmission direction is small. In this embodiment, the extension direction of the center line of the first discharge hole 106 is consistent with the signal transmission direction of the stable conductive terminal 110. The extension direction perpendicular to the center line of the first discharge hole 106, that is, the direction of the lateral width of the stable conductive terminal 110, is also the width direction of the stable conductive terminal 110, as shown in the figure. Figure 5 The direction of k is shown. The lateral width of each first discharge hole 106 is aligned with the lateral width of the stable conductive terminal 110.

[0078] like Figure 5 As shown, in one embodiment, the lateral width of any two first discharge holes 106 is equal, so that the capacitance difference between each position of the stable conductive terminal 110 is small, thereby reducing the crosstalk of adjacent signal transmissions of the stable conductive terminal 110.

[0079] like Figure 14As shown, in one embodiment, the stable conductive terminal 110 further includes a third interdigitated piece 110d protruding from the inner wall of the interdigitated forming area 102. The third interdigitated piece 110d is parallel to the second interdigitated piece 110c, and the third interdigitated piece 110d and the second interdigitated piece 110c are staggered from each other. The second interdigitated piece 110c is staggered from the first interdigitated piece 110b. Interdigitated gaps 104 are formed between the third interdigitated piece 110d and the first interdigitated piece 110b, and between the second interdigitated piece 110c and the first interdigitated piece 110b. The interdigitated gap 104 formed between the third interdigitated piece 110d and the first interdigitated piece 110b is the first interdigitated gap, and the interdigitated gap 104 formed between the second interdigitated piece 110c and the first interdigitated piece 110b is the second interdigitated gap. The first interdigitated gap and the second interdigitated gap are interconnected. In this embodiment, the interdigitated structure includes a first interdigitated piece 110b, a second interdigitated piece 110c, and a third interdigitated piece 110d, i.e., the number of interdigitated pieces is three. In other embodiments, the number of interdigitated pieces may be four, five, or other numbers. Further, the first interdigitated gap is equal to the second interdigitated gap, and neither the first nor the second interdigitated gap is equal to the interdigitated width. In other embodiments, the first and second interdigitated gaps may also be equal to the interdigitated width.

[0080] like Figure 5 As shown, in one embodiment, at least one of the first interdigitated sheet 110b and the second interdigitated sheet 110c has a second discharge hole 109. In this embodiment, the first interdigitated sheet 110b having a second discharge hole 109 provides better compatibility. In other embodiments, the second discharge hole 109 is not limited to being formed in the first interdigitated sheet 110b. For example, both the first interdigitated sheet 110b and the second interdigitated sheet 110c have second discharge holes 109. Further, at least one of the first interdigitated sheet 110b, the second interdigitated sheet 110c, and the third interdigitated sheet 110d has a second discharge hole 109, providing better compatibility for at least one of the first interdigitated sheet 110b, the second interdigitated sheet 110c, and the third interdigitated sheet 110d. For example, all three interdigitated sheets 110b, the second interdigitated sheet 110c, and the third interdigitated sheet 110d have second discharge holes 109.

[0081] Compared with the prior art, the present invention has at least the following advantages:

[0082] The aforementioned stable conductive terminal 110, because the conductive terminal body 110a has an interdigitated molding area 102, and the first interdigitated piece 110b and the second interdigitated piece 110c are both protruding from the inner wall of the interdigitated molding area 102, the first interdigitated piece 110b and the second interdigitated piece 110c are parallel to each other, and an interdigitated gap 104 is formed between the first interdigitated piece 110b and the second interdigitated piece 110c, so that the stable conductive terminal 110 forms a capacitance area in the interdigitated molding area 102, thereby improving the capacitance of the stable conductive terminal 110 in the interdigitated molding area 102, and making the stable conductive terminal have It has good inductive impedance, and because the conductive terminal body has multiple floating deformation parts formed along the extension direction, and multiple first blanking holes are sequentially opened along the extension direction of the conductive terminal body, each floating deformation part has at least one first blanking hole, the conductive terminal body has good floating performance and inductive impedance, and at the same time, the stable conductive terminal has a good bandpass filtering effect for high frequency signal transmission, that is, the bandpass filtering effect for high frequency signal transmission is more obvious, avoiding the problem of severe crosstalk between adjacent conductive terminals during signal transmission in floating connectors.

Therefore, the protection scope of this invention patent should be determined by the appended claims.
