[0024] This application provides a floating terminal assembly. The floating terminal assembly includes a floating terminal, a first protruding finger and a second protruding finger. The floating terminal includes a fixed portion, a floating bending portion and a conductive contact portion connected in sequence. The fixed portion and the floating bending portion enclose a first floating opening region. The floating bending portion includes a plurality of bending corner structures. The first protruding finger is located within the first floating opening region. One end of the first protruding finger is connected to the fixed portion, and the other end of the first protruding finger is suspended within the first floating opening region. The second protruding finger is located within the first floating opening region. One end of the second protruding finger is connected to the floating bending portion, and the other end of the second protruding finger is suspended within the first floating opening region. There is an interdigital capacitance region between the first protruding finger and the second protruding finger.

[0025] In the floating terminal assembly, the floating terminal includes a fixed portion, a floating bending portion, and a conductive contact portion that are connected in sequence. The floating bending portion includes a plurality of curved corner structures, and the first floating opening region is surrounded by the fixed portion and the floating bending portion, so that the floating terminal assembly has good floating performance and high inductive impedance. Further, the first protruding finger and the second protruding finger are located within the first floating opening region, one end of the first protruding finger is connected to the fixed portion, the other end of the first protruding finger is suspended in the first floating opening region, one end of the second protruding finger is connected to the floating bending portion, the other end of the second protruding finger is suspended in the first floating opening region, and an interdigital capacitance region exists between the first protruding finger and the second protruding finger. Thus, an interdigital structure is formed in the first floating opening region, and the interdigital structure generates an interdigital capacitance, so that the inductive impedance generated by the floating bending portion is preferably neutralized. Furthermore, the floating terminal assembly not only has good floating performance, but also the inductive impedance of the floating terminal assembly preferably reaches a predetermined target value, and the signal transmission of the floating terminal assembly is more reliable.

[0026] To better understand the technical means and beneficial effects of the present application, the present application will be described in more detail below with reference to specific embodiments.

[0027] As shown in FIGS. 1 and 1a, a floating terminal assembly 100 according to an embodiment includes a floating terminal 110, a first protruding finger 120, and a second protruding finger 130. The floating terminal 110 includes a fixed portion 112, a floating bending portion 114, and a conductive contact portion 116 that are connected in sequence. The first floating opening region 102 is surrounded by the fixed portion 112 and the floating bending portion 114, and the floating bending portion 114 includes a plurality of curved corner structures 114a.

[0028] As shown in FIGS. 1 and 1a, in one embodiment, the first protruding finger 120 is located within the first floating opening region 102. One end of the first protruding finger 120 is connected to the fixed portion 112, and the other end of the first protruding finger 120 is suspended in the first floating opening region 102. The second protruding finger 130 is located within the first floating opening region 102. One end of the second protruding finger 130 is connected to the floating bending portion 114, and the other end of the second protruding finger 130 is suspended in the first floating opening region 102. Since there is an interdigital capacitance region between the first protruding finger 120 and the second protruding finger 130, there is an interdigital gap between the first protruding finger 120 and the second protruding finger 130. In this embodiment, the first protruding finger 120 and the second protruding finger 130 are provided offset from each other, and there is an interdigital gap 125 between one end of the first protruding finger 120 suspended in the first floating opening region 102 and one end of the second protruding finger 130 suspended in the first floating opening region 102.

[0029] In the floating terminal assembly 100, the floating terminal 110 includes a fixed portion 112, a floating bending portion 114, and a conductive contact portion 116 that are connected in sequence. The floating bending portion 114 includes a plurality of bending corner structures 114a. The first floating opening region 102 is surrounded by the fixed portion 112 and the floating bending portion 114, so that the floating terminal assembly 100 has good floating performance and high inductive impedance. Further, the first protruding finger 120 and the second protruding finger 130 are located within the first floating opening region 102. One end of the first protruding finger 120 is connected to the fixed portion 112, and the other end of the first protruding finger 120 is suspended in the first floating opening region 102. One end of the second protruding finger 130 is connected to the floating bending portion 114, and the other end of the second protruding finger 130 is suspended in the first floating opening region 102. Since there is an interdigital capacitance region between the first protruding finger 120 and the second protruding finger 130, an interdigital structure is formed in the first floating opening region 102. The interdigital structure generates an interdigital capacitance, which can well neutralize the inductive impedance generated by the floating bending portion 114. Furthermore, the floating terminal assembly 100 not only has good floating performance, but also the inductive impedance of the floating terminal assembly 100 can well reach a predetermined target value, and the signal transmission of the floating terminal assembly 100 is more reliable.

[0030] As shown in FIG. 1a, in one embodiment, the first protruding finger 120 is located within the first floating opening region 102. One end of the first protruding finger 120 is connected to the fixed portion 112, and the other end of the first protruding finger 120 is suspended in the first floating opening region 102. The second protruding finger 130 is located within the first floating opening region 102. One end of the second protruding finger 130 is connected to the floating bending portion 114, and the other end of the second protruding finger 130 is suspended in the first floating opening region 102. Due to the existence of an interdigital capacitance region between the first protruding finger 120 and the second protruding finger 130, there is an interdigital gap between the first protruding finger 120 and the second protruding finger 130, and the first protruding finger 120 and the second protruding finger 130 constitute the interdigital structure of the floating terminal assembly 100, that is, the vertical interdigital structure.

[0031] Furthermore, FIG. 2 is an equivalent circuit diagram of the vertical interdigital structure. The fixed portion 112 and the floating bending portion 114 may each be equivalent to the power supply lines on both sides of the vertical interdigital structure, and L f1 、L f2 are respectively the inductances of the two power supply lines. That is, the inductance corresponding to the fixed portion 112 is L f1 and the inductance corresponding to the floating bending portion 114 is L f2 . C t is the capacitance to ground of the terminal line, C 11 is the capacitance to ground of the first protruding finger 120, that is, the capacitance to ground of the left interdigital-shaped sheet, and C 22 is the capacitance to ground of the second protruding finger 130, that is, the capacitance to ground of the right interdigital-shaped sheet. R is the resistance of the interdigital-shaped sheet, L is the inductance of the interdigital-shaped sheet, and C 12 is the interdigital capacitance of the interdigital-shaped sheet. C t is C 11 and C 22 may be integrated respectively.

[0032] Assuming that the floating terminal is a lossless material, R can be ignored, and a simplified equivalent circuit as shown in FIG. 3 can be obtained. From the simplified equivalent circuit, it can be seen that the vertical interdigital structure is a band-pass model. In the equivalent circuit, C 12 is equal to the interdigital capacitance value of the interdigital capacitance of the interdigital sheet.

[0033] As shown in FIGS. 1a and 2, under the condition of a dielectric plate with a limited thickness, the thickness of the dielectric plate is much larger than the width of the interdigital fingers and the interdigital gap 125. In one embodiment, when the width of the interdigital fingers is equal to the interdigital gap 125, the calculation formula for C 12 is as follows.

[0034]

Equation

[0035] n is the number of interdigital fingers, l is the length of the interdigital fingers, the unit is mm, and ε r is the dielectric constant of the dielectric plate. In one embodiment, the dielectric plate is a plate holder for attaching the floating terminal assembly.

[0036] In one embodiment, when the width of the interdigital fingers is not equal to the gap, the calculation formula for C 12 is as follows.

[0037]

Equation

[0038] G is a constant coefficient, and W is the width of the interdigital fingers.

[0039] As can be seen from the above two formulas, the interdigital capacitance C 12 increases as the length of the interdigital fingers increases, and the interdigital capacitance C 12It becomes smaller as the gap between the interleaved fingers increases. As shown in FIGS. 1a and 2, the length of the interleaved fingers is the length e of the first protruding finger 120 or the length f of the second protruding finger 130. In this embodiment, the length e of the first protruding finger 120 is equal to the length f of the second protruding finger 130, and both are l.

[0040] Regarding the linear transmission of signals, the calculation formula for the generated linear inductance is as follows.

[0041]

Number

[0042]

Number

[0043] l is the length of the straight line, with the unit of μm. W is the width of the straight line, t is the thickness of the metal, i.e., the thickness of the terminal, and h is the thickness of the dielectric plate. As can be seen from the above formula, the linear inductance L (nH) becomes smaller as the width W of the straight line increases, and becomes larger as the length l of the straight line increases.

[0044] Similarly, the above calculation formula for linear inductance is also applicable to the inductance of the vertical interleaved finger structure. When applied to the inductance calculation of the vertical interleaved finger structure, l is the length of the interleaved finger, W is the width of the interleaved finger. Similarly, it can be seen that the inductance of the vertical interleaved finger structure becomes smaller as the width of the interleaved finger increases, and becomes larger as the length of the interleaved finger increases. However, for a floating terminal assembly having a vertical interleaved finger structure, the inductance value of the vertical interleaved finger structure, i.e., the interleaved finger inductance, is very small and can be ignored.

[0045] As shown in FIG. 1a, the floating bending portion 114 of the floating terminal assembly 100 includes a plurality of curved corner structures 114a, and the first floating opening region 102 is surrounded by the fixed portion 112 and the floating bending portion 114. The floating terminal assembly 100 floats in the air, and further, the floating terminal assembly 100 can form many straight connection structures. For example, as shown in FIG. 1, at least one straight connection structure is formed between two adjacent curved corner structures 114a. In this embodiment, the first floating opening region 102 is surrounded by the fixed portion 112 and the floating bending portion 114 of the floating terminal assembly 100. Note that within a certain space between the fixed portion 112 and the conductive contact portion 116, the floating bending portion 114 has a long straight length with respect to a normal terminal structure. Thus, the sum of the linear inductances generated by the floating bending portion 114 of the floating terminal assembly 100 is large. Further, the sum of the linear inductances generated by the floating terminal assembly 100 is large, and its equivalent model is shown in FIG. 4, and the corresponding simplified equivalent circuit diagram is shown in FIG. 5. Thereby, the floating terminal assembly 100 has good floating performance and high inductive impedance, and the generated impedance curve is the solid line shown in FIG. 6. Also, an interdigital structure is formed within the first floating opening region 102, and an interdigital capacitance region exists between the first protruding finger 120 and the second protruding finger 130. Thus, the interdigital structure of the floating terminal assembly 100 can form an interdigital capacitor. In accordance with the above analysis, the interdigital structure mainly exhibits capacitive characteristics, and its corresponding simplified equivalent circuit diagram is shown in FIG. 7, and the generated impedance curve is the dashed line shown in FIG. 6.As can be seen from the comparison diagram of the impedance curves of terminal signal transmission shown in FIG. 6, by providing interdigital capacitors in parallel at both ends of the inductor, the inductive impedance value of a single inductor can be reduced. That is, the interdigital structure of the floating terminal assembly 100 can neutralize the inductive impedance. In this way, the inductive impedance value of the entire floating terminal assembly 100 is reduced to a predetermined value. The peak value of the dashed line shown in FIG. 6 is significantly lower than the peak value of the solid line. Furthermore, not only does the floating terminal assembly 100 have good floating performance, but also the inductive impedance of the floating terminal assembly 100 reaches the predetermined target value well, making the signal transmission of the floating terminal assembly 100 more reliable.

[0046] As shown in FIG. 1a again, in one embodiment, the floating bending portion 114 further includes a plurality of straight connection portions 114b. Two adjacent floating bending portions 114 are connected by one straight connection portion 114b, and two adjacent straight connection portions 114b of the floating bending portion are provided at intervals. Within a certain space between the fixed portion 112 and the conductive contact portion 116, the floating bending portion 114 has a long straight length with respect to a normal terminal structure, that is, the number of formed straight connection portions 114b is large, that is, the total sum of the generated straight inductance is large. The floating terminal assembly 100 has good floating performance and high inductive impedance, and an interdigital capacitance region exists better between the first protruding finger 120 and the second protruding finger 130 in the first floating opening region 102.

[0047] As shown in FIG. 1 again, in one embodiment, the first protruding finger 120 and the second protruding finger 130 are parallel to each other.

[0048] As shown in FIG. 1 again, in this embodiment, the number of the first protruding fingers 120 and the number of the second protruding fingers 130 are both one. In other embodiments, the number of the first protruding fingers 120 and the number of the second protruding fingers 130 are not limited to one. For example, the number of the first protruding fingers 120 and the number of the second protruding fingers 130 are both two. One second protruding finger 130 is provided between two adjacent first protruding fingers 120, and one first protruding finger 120 is provided between two adjacent second protruding fingers 130, whereby the two first protruding fingers 120 and the two second protruding fingers 130 are provided at intervals. In addition, in other embodiments, the number of the first protruding fingers 120 is not limited to being equal to the number of the second protruding fingers 130. For example, the number of the first protruding fingers 120 is one more than the number of the second protruding fingers 130. Also, for example, the number of the first protruding fingers 120 is one less than the number of the second protruding fingers 130.

[0049] As shown in FIG. 1a again, in one embodiment, the second floating opening region 104 is surrounded by the conductive contact portion 116 and the floating bending portion 114, and the second floating opening region 104 and the first floating opening region 102 are respectively located on both sides of the floating bending portion 114, so that the structure of the floating terminal assembly 100 becomes more compact, and the floating terminal assembly 100 has good floating performance and high inductive impedance.

[0050] As shown in FIG. 1a again, in one embodiment, the floating terminal assembly 100 further includes a third protruding finger 140 and a fourth protruding finger 150. One end of the third protruding finger 140 is connected to the side of the floating bending portion 114 opposite to the second protruding finger 130. The other end of the third protruding finger 140 is suspended in the second floating opening region 104. One end of the fourth protruding finger 150 is connected to the conductive contact portion 116. The other end of the fourth protruding finger 150 is suspended in the second floating opening region 104. And both the third protruding finger 140 and the fourth protruding finger 150 are located in the second floating opening region 104. The third protruding finger 140 and the fourth protruding finger 150 are provided offset from each other. By surrounding the second floating opening region 104 with the conductive contact portion 116 and the floating bending portion 114, the floating terminal assembly 100 has good floating performance and high inductive impedance. Also, by providing the third protruding finger 140 and the fourth protruding finger 150 offset from each other, interdigital structures are formed in both the first floating opening region 102 and the second floating opening region 104. Each interdigital structure can generate an interdigital capacitance, which can well neutralize the inductive impedance generated by the floating bending portion 114. Furthermore, the floating terminal assembly 100 not only has good floating performance, but also the inductive impedance of the floating terminal assembly 100 reaches the predetermined target value well, and the signal transmission of the floating terminal assembly 100 is more reliable.

[0051] As shown in FIG. 1a again, in one embodiment, the floating terminal 110, the first protruding finger 120, the second protruding finger 130, the third protruding finger 140, and the fourth protruding finger 150 have an integrally punched and formed structure. Thereby, the processing difficulty of the floating terminal assembly 100 is low, the structure is compact, and the floating terminal 110, the first protruding finger 120, the second protruding finger 130, the third protruding finger 140, and the fourth protruding finger 150 are securely fixedly connected.

[0052] As shown in FIG. 1a again, in one embodiment, the width of the first protruding finger 120 is equal to the width of the second protruding finger 130. Thereby, the finger capacitance of the interdigital structure formed by the first protruding finger 120 and the second protruding finger 130 is good.

[0053] As shown in FIG. 1a again, in one embodiment, the width of the third protruding finger 140 is equal to the width of the fourth protruding finger 150. Thereby, the finger capacitance of the interdigital structure formed by the third protruding finger 140 and the fourth protruding finger 150 is good.

[0054] As shown in FIG. 1 again, in one embodiment, the minimum gap value between the first protruding finger 120 and the second protruding finger 130 is equal to or different from the width of the first protruding finger 120. In this embodiment, the minimum gap value between the first protruding finger 120 and the second protruding finger 130 is equal to the width of the first protruding finger 120. In other embodiments, the minimum gap value between the first protruding finger 120 and the second protruding finger 130 is different from the width of the first protruding finger 120. For example, the minimum gap value between the first protruding finger 120 and the second protruding finger 130 is smaller or larger than the width of the first protruding finger 120.

[0055] In one embodiment, the minimum gap value between the third protruding finger 140 and the fourth protruding finger 150 is equal to or different from the width of the third protruding finger 140. In this embodiment, the minimum gap value between the third protruding finger 140 and the fourth protruding finger 150 is equal to the width of the third protruding finger 140. In other embodiments, the minimum gap value between the third protruding finger 140 and the fourth protruding finger 150 is different from the width of the third protruding finger 140.
