[0025] This application provides a stable conductive terminal. The stable conductive terminal includes a conductive terminal body, a first cross-finger-shaped sheet and a second cross-finger-shaped sheet respectively formed on the conductive terminal body. An intersection finger forming region is formed on the conductive terminal body. The first cross-finger-shaped sheet and the second cross-finger-shaped sheet are both protrudingly provided on the inner wall of the intersection finger forming region. The first cross-finger-shaped sheet and the second cross-finger-shaped sheet are parallel to each other, and an intersection finger gap is formed between the first cross-finger-shaped sheet and the second cross-finger-shaped sheet. A plurality of floating deformation parts are formed on the conductive terminal body along the extending direction.

[0026] In the above-described stable conductive terminal, an interdigital forming region is formed in the conductive terminal body, and both the first interdigital sheet and the second interdigital sheet are protruded from the inner wall of the interdigital forming region. The first interdigital sheet and the second interdigital sheet are parallel to each other, and an interdigital gap is formed between the first interdigital sheet and the second interdigital sheet. Therefore, in the stable conductive terminal, an interdigital capacitance region is formed in the interdigital forming region, improving the capacitance of the stable conductive terminal in the interdigital forming region, thereby enabling the stable conductive terminal to have good inductive impedance. Further, a plurality of floating deformation portions are formed in the conductive terminal body along the extending direction, and a plurality of first punching holes are sequentially formed in the conductive terminal body along the extending direction. At least one first punching hole is provided in each floating deformation portion. Therefore, the conductive terminal body has good floating performance and inductive impedance, and the stable conductive terminal has a good band-pass filtering effect on the transmission of high-frequency signals, that is, the band-pass filtering effect on the transmission of high-frequency signals is remarkable, avoiding the problem that crosstalk becomes serious during signal transmission between two adjacent conductive terminals of the floating connector.

[0027] To better understand the technical means and beneficial effects of the present application, the present application will be further described in detail below with reference to specific embodiments.

[0028] As shown in FIGS. 1 to 4, a floating connector assembly 10 according to an embodiment includes a first connector 100 and a second connector 200. The first connector 100 is inserted into the second connector 200 to achieve a floating connection between the first connector 100 and the second connector 200. In this embodiment, the first connector 100 includes a stable conductive terminal 110. Specifically, the first connector 100 further includes a first connection base 120 and a floating socket 130. A floating groove 122 and a first engagement groove 124 that communicate with each other are formed in the first connection base 120. The floating socket 130 is movably provided in the floating groove 122 and is movable with respect to the first connection base 120.

[0029] As shown in FIGS. 1 to 4, further, the floating socket 130 is formed with a second engaging groove 132 and a first insertion groove opening 134 that communicate with each other. One end of the stable conductive terminal 110 is inserted into the first engaging groove 124, the other end of the stable conductive terminal 110 is inserted into the second engaging groove 132, and one end of the stable conductive terminal 110 is located within the first insertion groove opening 134. The second connector 200 includes a second connection base 210 and a male terminal 220. The second connection base 210 is formed with a second insertion groove opening 212, and an insertion tab 2122 protrudes from the second insertion groove opening 212. The male terminal 220 is provided on the second connection base 210, and the male terminal 220 protrudes from the side wall of the insertion tab 2122. The first connection base 120 is inserted into the second insertion groove opening 212, the insertion tab 2122 is inserted into the first insertion groove opening 134, and the male terminal 220 elastically abuts against the stable conductive terminal 110. Thereby, when the first connector 100 is inserted into the second connector 200, the first connector 100 is electrically connected to the second connector 200.

[0030] Furthermore, the number of male terminals 220 and the number of stable conductive terminals 110 are both at least four. The number of first engaging grooves 124 and the number of second engaging grooves 132 are both at least four. The four first engaging grooves 124 all communicate with the floating groove body 122, and the four second engaging grooves 132 all communicate with the first insertion groove opening 134. Both ends of each stable conductive terminal 110 are inserted into the corresponding first engaging groove 124 and the corresponding second engaging groove 132 respectively, and each stable conductive terminal 110 elastically abuts against the corresponding male terminal 220. Thereby, each stable conductive terminal 110 is electrically connected to the corresponding male terminal 220. Specifically, the four stable conductive terminals are the first stable conductive terminal, the second stable conductive terminal, the third stable conductive terminal, and the fourth stable conductive terminal respectively, and the first stable conductive terminal, the second stable conductive terminal, the third stable conductive terminal, and the fourth stable conductive terminal are arranged side by side in sequence. The first stable conductive terminal and the fourth stable conductive terminal are both ground terminals and jointly form a ground terminal group. The second stable conductive terminal and the third stable conductive terminal are both differential signal terminals and jointly form a differential signal terminal group.

[0031] As shown in FIGS. 2, 4, 5, and 5a, in one embodiment, the stable conductive terminal 110 includes a conductive terminal body 110a, a first cross-finger-shaped sheet 110b, and a second cross-finger-shaped sheet 110c respectively formed on the conductive terminal body 110a. An intersection finger forming region 102 is formed on the conductive terminal body 110a, and both the first cross-finger-shaped sheet 110b and the second cross-finger-shaped sheet 110c protrude from the inner wall of the intersection finger forming region 102. The first cross-finger-shaped sheet 110b and the second cross-finger-shaped sheet 110c are parallel to each other, and an intersection finger gap 104 is formed between the first cross-finger-shaped sheet 110b and the second cross-finger-shaped sheet 110c, whereby an intersection finger capacitance region is formed in the intersection finger forming region 102. A plurality of floating deformation portions 1103 are formed on the conductive terminal body 110a along the extending direction, and a plurality of first punching holes 106 are sequentially formed on the conductive terminal body 110a along the extending direction. At least one of the first punching holes 106 is provided in each of the floating deformation portions 1103.

[0032] In the above-described stable conductive terminal 110, an interdigital forming region 102 is formed in the conductive terminal body 110a, and both the first interdigital sheet 110b and the second interdigital sheet 110c are protrudingly provided on the inner wall of the interdigital forming region 102. The first interdigital sheet 110b and the second interdigital sheet 110c are parallel to each other, and an interdigital gap 104 is formed between the first interdigital sheet 110b and the second interdigital sheet 110c. Therefore, in the stable conductive terminal 110, an interdigital capacitance region is formed in the interdigital forming region 102, improving the capacitance of the stable conductive terminal 110 in the interdigital forming region 102, thereby enabling the stable conductive terminal to have good inductive impedance. Further, a plurality of floating deformation portions are formed in the conductive terminal body along the extending direction, and a plurality of first punching holes are sequentially formed in the conductive terminal body along the extending direction. At least one first punching hole is provided in each floating deformation portion. Therefore, the conductive terminal body has good floating performance and inductive impedance, and the stable conductive terminal has a good band-pass filtering effect on the transmission of high-frequency signals, that is, the band-pass filtering action on the transmission of high-frequency signals is remarkable, avoiding the problem that crosstalk becomes serious during signal transmission between two adjacent conductive terminals of the floating connector.

[0033] As shown in FIG. 5 or FIG. 5a, for the stable conductive terminal 110, the first interdigital sheet 110b and the second interdigital sheet 110c are parallel to each other, and an interdigital gap 104 is formed between the first interdigital sheet 110b and the second interdigital sheet 110c. Therefore, in the stable conductive terminal 110, a vertical interdigital structure, which is an interdigital capacitance region, is formed in the interdigital forming region 102. As a result, the capacitance of the stable conductive terminal 110 in the interdigital forming region 102 is improved, and the stable conductive terminal has good inductive impedance. In addition, since the first punching hole 106 is formed in the conductive terminal body 110a, the stable conductive terminal 110 has a good band-pass filtering effect on the transmission of high-frequency signals, that is, the band-pass filtering effect on the transmission of high-frequency signals is remarkable, and the problem that crosstalk becomes serious during signal transmission between two adjacent conductive terminals of the floating connector is avoided.

[0034] Furthermore, as shown in FIG. 5 at the same time, the conductive terminal body 110a includes a welding and fixing segment 1102, a bending segment 1104, and an engaging segment 1106, and the welding and fixing segment 1102, the bending segment 1104, and the engaging segment 1106 are connected in sequence. As shown in FIGS. 5 and 14, furthermore, the bending segment 1104 is N-shaped or S-shaped. In one embodiment, the interdigital forming region 102 is formed between the bending segment 1104 and the welding and fixing segment 1102.

[0035] FIG. 6 is an equivalent circuit diagram of the vertical interdigital structure. The welding and fixing segment 1102 and the engaging segment 1106 may each be equivalent to the power supply lines on both sides of the vertical interdigital structure, and L f1 , L f2 are the inductances of the two power supply lines respectively, that is, the inductance corresponding to the welding and fixing segment 1102 is L f1 , and the inductance corresponding to the engaging segment 1106 is L f2 , C t is the capacitance to ground of the terminal line, and C 11is the capacitance to the ground of the first interdigital sheet 110b, that is, the capacitance to the ground of the left interdigital sheet, C 22 is the capacitance to the ground of the second interdigital sheet 110c, that is, the capacitance to the ground of the right interdigital sheet. R is the resistance of the interdigital sheet, L is the inductance of the interdigital sheet, C 12 is the interdigital capacitance of the interdigital sheet. C t is C 11 and C 22 may be integrated with each other respectively. Assuming that the stable conductive terminal 110 is a lossless material, R can be ignored, and a simplified equivalent circuit diagram shown in FIG. 7 can be obtained.

[0036] From the simplified equivalent circuit, it can be seen that the vertical interdigital structure is a band-pass model. C 12 in the equivalent circuit is equal to the interdigital capacitance value of the interdigital capacitance of the interdigital sheet.

[0037] As shown in FIGS. 5 and 6, 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 finger gap 104. As shown in FIG. 6, in this embodiment, the width d of the interdigital fingers is the width of the interdigital sheet. In one embodiment, when the width of the interdigital fingers is equal to the gap, C 12 is calculated as follows.

[0038]

Equation

[0039] n is the number of interdigital fingers, l is the length of the interdigital fingers, the unit is mm, ε r is the dielectric constant of the dielectric plate.

[0040] As shown in FIG. 4, in one embodiment, the dielectric plate is a plate holder for attaching a floating terminal assembly. In this embodiment, the dielectric plate is the first connection base 120 or the floating socket 130.

[0041] In one embodiment, when the width of the interdigital fingers is not equal to the gap, the calculation formula of C 12 is as follows.

[0042]

Equation

[0043] G is a constant coefficient, and W is the width of the interdigital fingers.

[0044] 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 12 decreases as the increase of the interdigital gap 104. As shown in FIGS. 5 and 6, the length of the interdigital fingers is the length e of the first interdigital-shaped sheet 110b or the length f of the second interdigital-shaped sheet 110c. In this embodiment, the length e of the first interdigital-shaped sheet 110b is equal to the length f of the second interdigital-shaped sheet 110c, and both are l.

[0045] Regarding the linear transmission of signals, the calculation formula of the generated linear inductance is as follows.

[0046]

Equation

[0047]

Equation

[0048] l is the length of the straight line, the unit is μm, W is the width of the straight line, t is the thickness of the metal, that is, 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 straight line increases and increases as the length l of the straight line increases.

[0049] Similarly, the above formula for calculating the linear inductance is also applicable to the inductance of the vertical cross-finger structure. When applied to the inductance calculation of the 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 with the increase in the width of the cross-finger and increases with the increase in the length of the cross-finger. However, for the floating terminal assembly having a vertical cross-finger structure, the numerical value of the inductance of the vertical cross-finger structure, that is, the cross-finger inductance, is very small and can be ignored.

[0050] As shown in FIGS. 2 and 5, for the stable conductive terminal 110, the conductive terminal body 110a has a high inductive impedance. Under the condition that the interdigital structure and the first punching hole 106 are not provided, the equivalent circuit model of the conductive terminal is shown in FIG. 8, the corresponding simplified equivalent circuit diagram is shown in FIG. 9, and the impedance peak generated correspondingly is the peak value of the solid line in the impedance curve diagram shown in FIG. 10. Under the condition that the interdigital structure is provided, an interdigital forming region 102 is formed between the curved segment 1104 and the welding and fixing segment 1102. The first interdigital-shaped sheet 110b and the second interdigital-shaped sheet 110c are both convexly provided on the inner wall of the interdigital forming region 102. The first interdigital-shaped sheet 110b and the second interdigital-shaped sheet 110c are parallel to each other, and an interdigital gap 104 is formed between the first interdigital-shaped sheet 110b and the second interdigital-shaped sheet 110c. Thereby, the stable conductive terminal 110 forms an interdigital capacitance region in the interdigital forming region 102. The simplified equivalent circuit diagram of the equivalent circuit model is shown in FIG. 11, and the impedance peak generated correspondingly is the peak value of the dashed line in the impedance curve diagram shown in FIG. 10. As can be seen from this, by adding and providing the interdigital-shaped sheets, that is, the first interdigital-shaped sheet 110b and the second interdigital-shaped sheet 110c, to the conductive terminal body 110a, the capacitance of the stable conductive terminal 110 in the interdigital forming region 102 is improved, and the stable conductive terminal has a better inductive impedance, that is, the inductive impedance of the stable conductive terminal is adjusted better to a predetermined value. The schematic diagram of the signal crosstalk of the adjacent stable conductive terminals 110 is the star point curve shown in FIG. 12.

[0051] Furthermore, a first punching hole is provided in the conductive terminal body 110a. In this embodiment, a plurality of first punching holes 106 are formed in the conductive terminal body 110a, that is, the number of the first punching holes 106 is plural, plural means two or more, including two. The simplified equivalent circuit diagram of its equivalent circuit model is shown in FIG. 13. At this time, the schematic diagram of the signal crosstalk of the adjacent stable conductive terminals 110 is shown by the solid line curve shown in FIG. 12. Thus, after loading the cross-finger capacitance, as can be seen from the schematic diagram of the crosstalk of the adjacent differential signals, a plurality of first punching holes 106 are formed in the conductive terminal body 110a, and the stable conductive terminal 110 has a good band-pass filtering effect on the transmission of high-frequency signals. That is, by providing the first punching hole in the conductive terminal body 110a, the band-pass filtering effect on the transmission of high-frequency signals is remarkable. That is, the resonance frequency of the crosstalk moves parallel to the high-frequency band, which is advantageous for the bandwidth of signal transmission, and the problem that the crosstalk becomes serious during signal transmission between two adjacent conductive terminals of the floating connector assembly 10 is avoided. Note that the number of the first punching holes 106 is one or two or three or four or plural. As shown in FIG. 15, the number of the first punching holes 106 is one. As shown in FIG. 5 or FIG. 14, the number of the first punching holes 106 is four.

[0052] As shown in FIGS. 5 and 8, in one embodiment, the conductive terminal body 110a is bent, and the curved segment 1104 includes a plurality of floating deformation portions 1103 and a plurality of linear structures 1105. The plurality of floating deformation portions 1103 and the plurality of linear structures are provided at intervals. One linear structure is provided between two adjacent floating deformation portions 1103, and one floating deformation portion 1103 is provided between two adjacent linear structures. Thereby, the conductive terminal body 110a not only has good floating property, but also can form more linear structures compared with the conventional conductive terminal. In this way, within the predetermined space of the welding and fixing segment 1102 and the engaging segment 1106, the conductive terminal body 110a has good linear inductance, and the conductive terminal body 110a has good inductive impedance. In this embodiment, an interleaved finger forming region 102 is formed between the curved segment 1104 and the welding and fixing segment 1102 of the conductive terminal body 110a. The curved segment 1104 includes a plurality of floating deformation portions 1103 and a plurality of linear structures 1105. The plurality of floating deformation portions 1103 and the plurality of linear structures are provided at intervals. One linear structure is provided between two adjacent floating deformation portions 1103, and one floating deformation portion 1103 is provided between two adjacent linear structures. The conductive terminal body 110a can form more linear structures. In this way, within the predetermined space of the welding and fixing segment 1102 and the engaging segment 1106, the conductive terminal body 110a has good linear inductance, and the conductive terminal body 110a has good inductive impedance. Further, the bending directions of the plurality of floating deformation portions 1103 are different, whereby the structure of the conductive terminal body 110a becomes compact, the curved segment 1104 has many linear structures, and further the curved segment 1104 has good inductive impedance. In other embodiments, as shown in FIG. 2a, the two adjacent floating deformation portions 1103 are not limited to being provided with one linear structure, that is, there is no linear structure between the two adjacent floating deformation portions 1103.

[0053] As shown in FIG. 5, further, the length of the first interdigital sheet 110b is equal to the length of the second interdigital sheet 110c, thereby forming a long interdigital capacitance region between the first interdigital sheet 110b and the second interdigital sheet 110c. Of course, in other embodiments, as shown in FIG. 5a, the length of the first interdigital sheet 110b may not be equal to the length of the second interdigital sheet 110c. For example, the length of the first interdigital sheet 110b is smaller than the length of the second interdigital sheet 110c.

[0054] As shown in FIG. 4, further, the welding fixing segment 1102 is inserted into the first engaging groove 124, whereby the welding fixing segment 1102 is fixedly connected to the first connection base 120. In other embodiments, a holding groove communicating with the first engaging groove 124 is further formed in the first connection base 120. As shown in FIG. 5a, a fixed end 1102a is formed at the connection location between the welding fixing segment 1102 and the curved segment 1104, and the fixed end 1102a is inserted into the holding groove, whereby both ends of the welding fixing segment 1102 are inserted into the first engaging groove 124 and the holding groove respectively, and further the welding fixing segment 1102 is firmly fixedly connected by the first connection base 120. Further, in the curved segment 1104, a holding and retracting groove 1102b is formed on the other side of the portion where the first interdigital sheet 110b is formed, to avoid interference with the insertion of the fixed end 1102a into the holding groove, and further ensure that the fixed end 1102a is inserted into the holding groove, and reduce the space occupied by the curved segment 110 along the floating direction, making the stable type conductive terminal 110 compact.

[0055] As shown in FIGS. 5 and 5a, in one embodiment, a plurality of first punching holes 106 are formed at intervals along the signal transmission direction of the conductive terminal body 110a. That is, on the conductive terminal body 110a, a plurality of first punching holes 106 are formed at intervals along the signal transmission direction, and it has a good band-pass filtering effect on the transmission of high-frequency signals. That is, the band-pass filtering effect on the transmission of high-frequency signals is remarkable, and the problem that crosstalk becomes serious during signal transmission between two adjacent conductive terminals of the floating connector assembly 10 is avoided. In other embodiments, the plurality of first punching holes 106 are not limited to being formed at intervals along the signal transmission direction of the conductive terminal body 110a. For example, the distances along the signal transmission direction of the conductive terminal body 110a between two adjacent first punching holes 106 are not equal.

[0056] As shown in FIGS. 5, 14, 15 and 16, in one embodiment, the interdigital forming region 102 is formed at at least one side or the middle position of the conductive terminal body 110a. As shown in FIG. 16, in this embodiment, the interdigital forming region 102 is formed on one side of the conductive terminal body 110a. In other embodiments, the interdigital forming region 102 is not limited to being formed on one side of the conductive terminal body 110a. For example, on both sides of the conductive terminal body 110a, interdigital forming regions 102 are both formed, and on the interdigital forming regions 102 on both sides of the conductive terminal body 110a, a first interdigital sheet 110b and a second interdigital sheet 110c which are provided opposite to each other and shifted from each other are provided. Furthermore, the number of the first interdigital sheets 110b and the number of the second interdigital sheets 110c are not limited to one each. As shown in FIG. 5, for example, the number of the first interdigital sheets 110b and the number of the second interdigital sheets 110c are both two. As shown in FIG. 15, of course, the number of the first interdigital sheets 110b and the number of the second interdigital sheets 110c are not limited to being equal. For example, the number of the first interdigital sheets 110b is more or less than the number of the second interdigital sheets 110c.

[0057] As shown in FIG. 14, in other embodiments, the interdigital forming region 102 is not limited to being formed on one or both sides of the conductive terminal body 110a. As shown in FIG. 15, for example, the interdigital forming region 102 may be formed at an intermediate position of the conductive terminal body 110a. Specifically, the interdigital forming region 102 is provided on the inner peripheral wall of one first punching hole 106, and both the first interdigital sheet 110b and the second interdigital sheet 110c are protruded on the inner peripheral wall of one first punching hole 106.

[0058] As shown in FIG. 14, in one embodiment, since each first punching hole 106 is a curved strip-shaped groove, it is easy to process and form each first punching hole 106, and each first punching hole 106 has good capacitance. As shown in FIG. 15, in other embodiments, each first punching hole 106 is not limited to a curved strip-shaped groove. For example, each first punching hole 106 is a linear strip-shaped groove, a rectangular groove, a waist groove or other grooves.

[0059] Furthermore, at least one first punching hole 106 is formed in each floating deformation part 1103, so that each floating deformation part 1103 has good elasticity, and further the curved segment 1104 has good elasticity, improving the floating property of the conductive terminal body 110a and enabling the conductive terminal body 110a to have a good band-pass filtering effect for high-frequency signal transmission. In this embodiment, one first punching hole 106 is formed in each floating deformation part 1103, and the first punching hole 106 is formed along the extending direction of the center line of the floating deformation part 1103.

[0060] As shown in FIGS. 5 and 14, furthermore, at least one first punching hole 106 is formed at both ends of the curved segment 1104, that is, at least one first punching hole 106 is formed at the positions adjacent to the welding and fixing segment 1102 and the engaging segment 1106 in the curved segment, so that the conductive terminal body 110a has a better band-pass filtering effect for high-frequency signal transmission.

[0061] As shown in FIGS. 5 and 14, in one embodiment, the center line of each first punching hole 106 overlaps with the center line of the conductive terminal body 110a, whereby the stable conductive terminal 110 has good capacitance, and further, the crosstalk of adjacent signal transmissions is better improved, and the structural strength of the stable conductive terminal 110 is improved.

[0062] As shown in FIGS. 5 and 14, in one embodiment, in the direction along the extending direction perpendicular to the center line of the first punching hole 106, the lateral widths of the first punching holes 106 are equal, whereby the difference in capacitance along the signal transmission direction in the first punching holes 106 of the stable conductive terminal 110 is reduced. In this embodiment, the extending direction of the center line of the first punching hole 106 coincides with the signal transmission direction of the stable conductive terminal 110. The extending direction perpendicular to the center line of the first punching hole 106 is the direction of the lateral width of the stable conductive terminal 110, the width direction of the stable conductive terminal 110, and the k direction shown in FIG. 5. The direction of the lateral width of each first punching hole 106 coincides with the direction of the lateral width of the stable conductive terminal 110.

[0063] As shown in FIG. 5, in one embodiment, since the width values of the lateral widths of any two first punching holes 106 are equal, the difference in capacitance at each position of the stable conductive terminal 110 is reduced, and further, the crosstalk of adjacent signal transmissions of the stable conductive terminal 110 is reduced.

[0064] As shown in FIG. 14, in one embodiment, the stable conductive terminal 110 further includes a third cross-finger-shaped sheet 110d protruding from the inner wall of the cross-finger forming region 102. The third cross-finger-shaped sheet 110d and the second cross-finger-shaped sheet 110c are parallel to each other, and the third cross-finger-shaped sheet 110d and the second cross-finger-shaped sheet 110c are provided with a shift from each other. The second cross-finger-shaped sheet 110c and the first cross-finger-shaped sheet 110b are provided with a shift from each other. A cross-finger gap 104 is formed between the third cross-finger-shaped sheet 110d and the second cross-finger-shaped sheet 110c, and between the second cross-finger-shaped sheet 110c and the first cross-finger-shaped sheet 110b. The cross-finger gap 104 formed between the third cross-finger-shaped sheet 110d and the second cross-finger-shaped sheet 110c is the first cross-finger gap, and the cross-finger gap 104 formed between the second cross-finger-shaped sheet 110c and the first cross-finger-shaped sheet 110b is the second cross-finger gap. The first cross-finger gap and the second cross-finger gap communicate with each other. In this embodiment, the cross-finger structure includes the first cross-finger-shaped sheet 110b, the second cross-finger-shaped sheet 110c, and the third cross-finger-shaped sheet 110d, that is, the number of cross-finger-shaped sheets is three. In other embodiments, the number of cross-finger-shaped sheets may be four, five, or other numbers. Further, the first cross-finger gap is equal to the second cross-finger gap, and neither the first cross-finger gap nor the second cross-finger gap is equal to the width of the cross-finger. In other embodiments, the first cross-finger gap and the second cross-finger gap may be equal to the width of the cross-finger.

[0065] As shown in FIG. 5, in one embodiment, at least one of the first interdigital sheet 110b and the second interdigital sheet 110c is formed with a second punching hole 109. In this embodiment, the second punching hole 109 is formed in the first interdigital sheet 110b, whereby the first interdigital sheet 110b has good capacitance. In other embodiments, the second punching hole 109 is not limited to being formed in the first interdigital sheet 110b. For example, the second punching hole 109 may be formed in both the first interdigital sheet 110b and the second interdigital sheet 110c. Further, at least one of the first interdigital sheet 110b, the second interdigital sheet 110c, and the third interdigital sheet 110d is formed with a second punching hole 109, whereby at least one of the first interdigital sheet 110b, the second interdigital sheet 110c, and the third interdigital sheet 110d has good capacitance. For example, the second punching hole 109 may be formed in all of the first interdigital sheet 110b, the second interdigital sheet 110c, and the third interdigital sheet 110d.

The first interdigital sheet 110b and the second interdigital sheet 110c are parallel to each other, and an interdigital gap 104 is formed between the first interdigital sheet 110b and the second interdigital sheet 110c. Therefore, in the stable conductive terminal 110, an interdigital capacitance region is formed in the interdigital forming region 102, improving the capacitance of the stable conductive terminal 110 in the interdigital forming region 102, so that the stable conductive terminal has good inductive impedance. Also, in the conductive terminal body, a plurality of floating deformation parts are formed along the extending direction, and a plurality of first punching holes are sequentially formed in the conductive terminal body along the extending direction.
