[0024] The present application provides a floating terminal assembly.

Furthermore, since the first and second protruding fingers are located within the first floating opening region, one end of the first protruding finger is connected to a fixed portion and the other end of the first protruding finger is suspended within the first floating opening region, one end of the second protruding finger is connected to a floating curved portion and the other end of the second protruding finger is suspended within the first floating opening region, and a cross-finger capacitance region exists between the first and second protruding fingers, a cross-finger structure is formed in the first floating opening region, and the cross-finger structure generates a cross-finger capacitance, which effectively neutralizes the inductive impedance generated by the floating curved portion. Moreover, the floating terminal assembly not only has good floating performance, but the inductive impedance of the floating terminal assembly reaches a predetermined target value well, making signal transmission of the floating terminal assembly more reliable.

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

[0027] As shown in Figures 1 and 1a, a floating terminal assembly 100 according to one 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 curved portion 114, and a conductive contact portion 116 connected in order, with the fixed portion 112 and the floating curved portion 114 surrounding a first floating opening region 102, and the floating curved portion 114 including a plurality of curved corner structures 114a.

[0028] As shown in Figures 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 within 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 curved portion 114, and the other end of the second protruding finger 130 is suspended within the first floating opening region 102. Due to the existence of a cross-finger capacity region between the first protruding finger 120 and the second protruding finger 130, a cross-finger gap exists 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 offset from each other, and a crossed finger gap 125 exists between one end of the first protruding finger 120, which is suspended in the first floating opening region 102, and one end of the second protruding finger 130, which is suspended in the first floating opening region 102.

[0029] In the floating terminal assembly 100 described above, the floating terminal 110 includes a fixed portion 112, a floating curved portion 114, and a conductive contact portion 116 that are connected in order, the floating curved portion 114 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 curved portion 114, so that the floating terminal assembly 100 has good floating performance and high inductive impedance. Furthermore, 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, the other end of the first protruding finger 120 is suspended within the first floating opening region 102, one end of the second protruding finger 130 is connected to the floating curved portion 114, the other end of the second protruding finger 130 is suspended within the first floating opening region 102, and there is an intersection between the first protruding finger 120 and the second protruding finger 130. Due to the presence of a finger capacitance region, a cross-finger structure is formed in the first floating opening region 102. This cross-finger structure generates cross-finger capacitance, which effectively neutralizes the inductive impedance generated in the floating curved portion 114. Furthermore, the floating terminal assembly 100 not only has good floating performance, but the inductive impedance of the floating terminal assembly 100 reaches a predetermined target value, making signal transmission of the floating terminal assembly 100 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 air within 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 air within 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, an interdigital gap exists 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-direction interdigital structure.

[0031] Furthermore, FIG. 2 is an equivalent circuit diagram of the vertical-direction 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-direction interdigital structure. 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 the ground of the terminal line, C 11 is the capacitance to the ground of the first protruding finger 120, that is, the capacitance to the ground of the left-side interdigital-shaped sheet, and C 22 is the capacitance to the ground of the second protruding finger 130, that is, the capacitance to the ground of the right-side 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 the floating terminals are made of lossless material, R can be ignored, and a simplified equivalent circuit can be obtained as shown in Figure 3. From the simplified equivalent circuit, it can be seen that the longitudinal cross-finger structure is a bandpass model. C in the equivalent circuit 12 This is equal to the cross-finger capacity value of the cross-finger sheet.

[0033] As shown in Figures 1a and 2, under the condition of a dielectric plate of a limited thickness, the thickness of the dielectric plate is much larger than the width of the crossed fingers and the gap between the crossed fingers 125. In one embodiment, when the width of the crossed fingers is equal to the gap between the crossed fingers 125, C 12 The formula for calculating this is as follows:

[0034]

number

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

[0036] In one embodiment, if the width of the crossed fingers is not equal to the gap, C 12 The formula for calculating this is as follows:

[0037]

number

[0038] G is a constant coefficient, and W is the width between crossed fingers.

[0039] As can be seen from the two equations above, the cross-finger capacity C 12 The crossed finger capacity C increases with increasing crossed finger length. 12This decreases as the gap between crossed fingers increases. As shown in Figures 1a and 2, the length of the crossed fingers is the length e of the first protruding finger 120 or the length f of the second protruding finger 130, and 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] The formula for calculating the linear inductance generated during linear signal transmission is as follows:

[0041]

number

[0042]

number

[0043] l is the length of the line, in units of μm; W is the width of the 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) decreases as the width W of the line increases, and increases as the length l of the line increases.

[0044] Similarly, the formula for calculating linear inductance described above also applies to the inductance of a vertical cross-finger structure. When applied to the calculation of the inductance of a vertical cross-finger structure, l is the length of the cross-finger and W is the width of the cross-finger. Similarly, it can be seen that the inductance of the vertical cross-finger structure decreases as the width of the cross-finger increases and increases as the length of the cross-finger increases. However, for floating terminal assemblies with a vertical cross-finger structure, the value of the inductance of the vertical cross-finger structure, i.e., the cross-finger inductance, is so small that it can be ignored.

[0045] As shown in Figure 1a, the floating curved 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 curved portion 114, so that the floating terminal assembly 100 floats in the air, and furthermore the floating terminal assembly 100 can form many linear connection structures, for example, as shown in Figure 1, at least one linear 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 curved portion 114 of the floating terminal assembly 100. Furthermore, within a certain space between the fixed portion 112 and the conductive contact portion 116, the floating curved portion 114 has a longer straight length than a normal terminal structure. Thus, the total linear inductance generated by the floating curved portion 114 of the floating terminal assembly 100 is large, and the total linear inductance generated by the floating terminal assembly 100 is also large. Its equivalent model is shown in Figure 4, and the corresponding simplified equivalent circuit diagram is shown in Figure 5. As a result, the floating terminal assembly 100 has good floating performance and high inductive impedance, and the corresponding impedance curve is the solid line shown in Figure 6. In addition, a cross-finger structure is formed within the first floating opening region 102, and a cross-finger capacitance region exists between the first protruding finger 120 and the second protruding finger 130, so that the cross-finger structure of the floating terminal assembly 100 can form a cross-finger type capacitor. In line with the above analysis, the cross-finger structure primarily exhibits capacitance characteristics, its corresponding simplified equivalent circuit diagram is shown in Figure 7, and the corresponding impedance curve is the dashed line shown in Figure 6.As can be seen from the comparison diagram of the impedance curves of terminal signal transmission shown in Figure 6, by providing cross-finger type capacitors in parallel with both ends of the inductor, the inductive impedance value of a single inductor can be reduced. In other words, the cross-finger structure of the floating terminal assembly 100 can neutralize the inductive impedance, thereby reducing the inductive impedance value of the entire floating terminal assembly 100 to a predetermined value. The peak value of the dashed line in Figure 6 is clearly lower than the peak value of the solid line. Furthermore, not only does the floating terminal assembly 100 have good floating performance, but the inductive impedance of the floating terminal assembly 100 reaches a predetermined target value well, making the signal transmission of the floating terminal assembly 100 more reliable.

[0046] As shown again in Figure 1a, in one embodiment, the floating curved portion 114 further includes a plurality of linear connection portions 114b, where two adjacent floating curved portions 114 are connected by one linear connection portion 114b, and two adjacent linear connection portions 114b of the floating curved portion are spaced apart. Within a certain space between the fixed portion 112 and the conductive contact portion 116, the floating curved portion 114 has a longer linear length than a normal terminal structure, that is, a larger number of formed linear connection portions 114b, that is, a larger total linear inductance, resulting in the floating terminal assembly 100 having good floating performance and high inductive impedance, and a better cross-finger capacitance region between the first protruding finger 120 and the second protruding finger 130 in the first floating opening region 102.

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

[0048] As shown again in Figure 1, in this embodiment, the number of first protruding fingers 120 and the number of second protruding fingers 130 are both one. In other embodiments, the number of first protruding fingers 120 and the number of second protruding fingers 130 are not limited to one. For example, the number of first protruding fingers 120 and the number of 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, thereby providing two first protruding fingers 120 and two second protruding fingers 130 with a gap between them. In other embodiments, the number of first protruding fingers 120 is not limited to being equal to the number of second protruding fingers 130. For example, the number of first protruding fingers 120 is one more than the number of second protruding fingers 130. Also, for example, the number of first protruding fingers 120 is one less than the number of second protruding fingers 130.

[0049] As shown again in Figure 1a, in one embodiment, the second floating opening region 104 is surrounded by the conductive contact portion 116 and the floating curved portion 114, and the second floating opening region 104 and the first floating opening region 102 are located on both sides of the floating curved portion 114, respectively. This makes the structure of the floating terminal assembly 100 more compact and gives the floating terminal assembly 100 good floating properties and high inductive impedance.

[0050] As shown again in Figure 1a, 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 being connected to the floating curved portion 114 on the side opposite to the second protruding finger 130, the other end of the third protruding finger 140 being suspended in the second floating opening region 104, one end of the fourth protruding finger 150 being connected to the conductive contact portion 116, and the other end of the fourth protruding finger 150 being connected to the second The floating terminal assembly 100 is suspended in the 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, with the third protruding finger 140 and the fourth protruding finger 150 offset from each other, and the second floating opening region 104 is surrounded by the conductive contact portion 116 and the floating curved portion 114, thereby providing good floating performance and high inductive impedance. Furthermore, by positioning the third protruding finger 140 and the fourth protruding finger 150 so as to be offset from each other, a cross-finger structure is formed in both the first floating opening region 102 and the second floating opening region 104. Each cross-finger structure can generate a cross-finger capacitance, which effectively neutralizes the inductive impedance generated by the floating curved portion 114. Moreover, the floating terminal assembly 100 not only has good floating performance, but the inductive impedance of the floating terminal assembly 100 reaches a predetermined target value well, making signal transmission of the floating terminal assembly 100 more reliable.

[0051] As shown again in Figure 1a, 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 are integrally stamped. This reduces the difficulty of processing the floating terminal assembly 100, makes the structure compact, and ensures that 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 fixed and connected.

[0052] As shown again in Figure 1a, in one embodiment, the width of the first protruding finger 120 is equal to the width of the second protruding finger 130. This results in good cross-finger capacity of the cross-finger structure formed by the first protruding finger 120 and the second protruding finger 130.

[0053] As shown again in Figure 1a, in one embodiment, the width of the third protruding finger 140 is equal to the width of the fourth protruding finger 150. This results in good cross-finger capacity of the cross-finger structure formed by the third protruding finger 140 and the fourth protruding finger 150.

[0054] As shown again in Figure 1, in one embodiment, the minimum gap 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 between the first protruding finger 120 and the second protruding finger 130 is equal to the width of the first protruding finger 120. In another embodiment, the minimum gap 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 between the first protruding finger 120 and the second protruding finger 130 is smaller than or larger than the width of the first protruding finger 120.

[0055] In one embodiment, the minimum gap 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 between the third protruding finger 140 and the fourth protruding finger 150 is equal to the width of the third protruding finger 140. In another embodiment, the minimum gap between the third protruding finger 140 and the fourth protruding finger 150 is different from the width of the third protruding finger 140. For example, the minimum gap between the third protruding finger 140 and the fourth protruding finger 150 is smaller than or larger than the width of the third protruding finger 140.
