[[Technical Field]]
[0001] The present disclosure relates to connectors and electronic devices. [[Background Art]]
[0002] For example, Patent Document 1 describes, as a circuit element mounted on an electronic device, a circuit board, a filter circuit, and a capacitance element that can cancel the parasitic inductance of the capacitance element and maintain the charge supply performance to electronic components. The circuit board is a circuit board on which a capacitance element is mounted, comprising: an electrode for connecting one terminal of the capacitance element; a first inductance element having a first wiring extending from one end connected to the first electrode across a region where the capacitance element is mounted to the other end; a second inductance element having a second wiring extending from one end connected to the first electrode across the region where the capacitance element is mounted from an opposite side to the first wiring to the other end; an input terminal connected to the other end of the second wiring; an output terminal connected to the other end of the first wiring; and a second electrode forming a capacitance between the output terminal and the second electrode, wherein the capacitance formed between the output terminal and the second electrode is greater than or equal to the capacitance of the capacitance element. As described above, the circuit board described in Patent Document 1 includes the first inductance element and the second inductance element, and since the capacitance formed between the output terminal and the second electrode is greater than or equal to the capacitance of the capacitance element, the parasitic inductance of the capacitance element is canceled out, and it is possible to maintain the charge supply performance for electronic components.

[0003] [[Patent Document 1]] International Publication No. 2017 / 110179 [[Summary of the Invention]] [[Problem to be Solved by the Invention]]
[0004] However, the conventional technology described in Patent Document 1 had a problem in that when the impedance of the noise source or the impedance of the load was high, around several hundred ohms, the performance of the circuit board, which acts as a noise filter, was not fully realized, and it was necessary to provide a separate noise filter in addition to the circuit board.
[0005] This disclosure aims to solve the above-mentioned problems and to provide a connector that can suppress electromagnetic noise without providing a separate filter, and electronic equipment using the same. [Means for solving the problem]
[0006] The connector according to this disclosure is a connector for connecting a first object and a second object, comprising: a first spring structure made of a coil-shaped winding with one end connected to the first object; a second spring structure made of a coil-shaped winding wound in the same direction as the first spring structure with one end connected to the second object, wherein the first spring structure and the second spring structure have windings that are insulated from each other and arranged alternately along the same direction, a conductor that electrically connects the other end of the first spring structure and the other end of the second spring structure; a first bypass capacitor with one electrode terminal connected to the first spring structure and the conductor and the other electrode terminal grounded; a second bypass capacitor with one electrode terminal connected to the first spring structure and the other electrode terminal grounded; and a third bypass capacitor with one electrode terminal connected to the second spring structure and the other electrode terminal grounded. [Effects of the Invention]
[0007] According to this disclosure, the invention comprises a first bypass capacitor in which one electrode terminal is connected to a first spring structure and a conductor and the other electrode terminal is grounded, a second bypass capacitor in which one electrode terminal is connected to the first spring structure and the other electrode terminal is grounded, and a third bypass capacitor in which one electrode terminal is connected to the second spring structure and the other electrode terminal is grounded. As a result, even when the impedance of the noise source or the load is high, such as several hundred ohms, a low impedance in parallel is present next to a high impedance in series, thereby improving the filtering performance of the connector according to this disclosure. In contrast, for example, the circuit board described in Patent Document 1 lacks a second and third bypass capacitor. Therefore, when the impedance of the noise source or the load is high, around several hundred ohms, a high series impedance is adjacent to another high series impedance, and the filtering performance of the circuit board is not fully realized. The connector according to this disclosure has a configuration in which a low impedance is present in parallel next to a high impedance in series, which improves the filtering performance of the connector and makes it possible to suppress electromagnetic noise without providing a separate filter. [Brief explanation of the drawing]
[0008] [Figure 1] This is a conceptual diagram illustrating the configuration of the electronic device according to Embodiment 1. [Figure 2] This is a schematic circuit diagram showing the main parts of the equivalent circuit of the connector according to Embodiment 1. [Figure 3] This is a schematic circuit diagram showing the equivalent circuit of the connector according to Embodiment 1. [Figure 4] This is a conceptual diagram illustrating the configuration of the electronic device according to Embodiment 2. [Modes for carrying out the invention]
[0009] Embodiment 1. Figure 1 is a conceptual diagram schematically showing the configuration of the electronic device 1 according to Embodiment 1. In Figure 1, the electronic device 1 has a structure in which a connection part 3 and a connection part 4a are connected by a connector 2 according to Embodiment 1. The connection part 3 is a first object electrically connected to a printed circuit board 5. The printed circuit board 5 is provided inside the housing 6 of the electronic device 1. The housing 6 is at a constant potential, for example, ground potential.
[0010] The connection part 4a is a second object such as an electrode terminal provided on the housing 6 of the electronic device 1, and a socket 4 is connected to the connection part 4a. The socket 4 is connected to a cable 7. By connecting the socket 4 to the connection part 4a, the connection part 4a is electrically connected to the core wire 8 inside the cable 7. By connecting the connection part 3 and the connection part 4a with the connector 2, it becomes possible to exchange signals between an external device (not shown) connected to the printed circuit board 5 and an external device (not shown) connected to the cable 7 via the connector 2.
[0011] Furthermore, connector 2 has a function to suppress electromagnetic noise. For example, if electronic device 1 is a high-frequency communication device, connector 2 functions as a noise filter to remove high-frequency electromagnetic noise leaking from the circuit of printed circuit board 5.
[0012] As shown in Figure 1, connector 2 comprises a first spring structure 21, a second spring structure 22, a conductor 23, and a first bypass capacitor 24, and further comprises a second bypass capacitor 30 and a third bypass capacitor 40. The first spring structure 21 is a spring structure made of a coil-shaped winding, with one end 21a connected to the connection part 3. The second spring structure 22 is a spring structure made of a coil-shaped winding wound in the same direction as the first spring structure 21, with one end 22a connected to the connection part 4a.
[0013] The first spring structure 21 and the second spring structure 22 are made of a conductive material. In Figure 1, the first spring structure 21 is shown with a white line and the second spring structure 22 with a black line, but the first spring structure 21 and the second spring structure 22 are made of conductive wire of the same material and dimensions. The outer circumferences of the first spring structure 21 and the second spring structure 22 are insulated so that they do not conduct electricity to each other directly. For example, non-conductive tape is wrapped around the outer circumferences of the first spring structure 21 and the second spring structure 22.
[0014] As described above, the first spring structure 21 and the second spring structure 22 are coil-shaped structures, and are arranged so that the winding axes of the windings coincide (coaxial). Furthermore, as described above, the windings of each turn of the first spring structure 21 and the second spring structure 22 are insulated from each other and are arranged alternately along the same direction. By arranging them in this way, the first spring structure 21 and the second spring structure 22 form mutual inductance through magnetic coupling. The parasitic inductance of the bypass circuit, including the first bypass capacitor 24, is canceled out by the equivalent negative inductance that appears in response to this mutual inductance. Furthermore, because the windings of the first spring structure 21 and the windings of the second spring structure 22 are arranged alternately at regular intervals without being separated, the magnetic coupling between them is large, and the equivalent negative inductance also becomes large.
[0015] Since the first spring structure 21 and the second spring structure 22 have a coil shape wound in the same direction and are connected in series via a conductor 23, current flows in the same direction through the first spring structure 21 and the second spring structure 22 in the connector 2. In addition, due to parasitic inductance, the magnetic flux generated inside the first spring structure 21 and the second spring structure 22 is also in almost the same direction.
[0016] The conductor 23 electrically connects the other end 21b of the first spring structure 21 to the other end 22b of the second spring structure 22. The first spring structure 21 and the second spring structure 22 are indirectly connected by the conductor 23. In Figure 1, the conductor 23 has a bent portion, but it may also have a straight wiring pattern. Alternatively, the conductor 23 may have a circular or elliptical wiring pattern.
[0017] The first bypass capacitor 24 has one electrode terminal connected to the first spring structure 21 and the conductive wire 23, and the other electrode terminal grounded. For example, as shown in Fig. 1, the first bypass capacitor 24 is connected via the conductive wire 25 to the connection point between the end 21b of the first spring structure 21 and the conductive wire 23, and is connected to the housing 6 via the conductive wire 26. Since the housing 6 is at ground potential, the other electrode terminal of the first bypass capacitor 24 is grounded. Note that the conductive wire 25 and the conductive wire 26 may be lead wires of the first bypass capacitor 24.
[0018] The second bypass capacitor 30 has one electrode terminal connected to the end 21a of the first spring structure, and the other electrode terminal grounded. For example, as shown in Fig. 1, the second bypass capacitor 30 is connected to the end 21a of the first spring structure via the conductive wire 31, and is connected to the housing 6 via the conductive wire 32. Since the housing 6 is at ground potential, the other electrode terminal of the second bypass capacitor 30 is grounded. Note that the conductive wire 31 and the conductive wire 32 may be lead wires of the second bypass capacitor 30.
[0019] The third bypass capacitor 40 has one electrode terminal connected to the end 22a of the second spring structure, and the other electrode terminal grounded. For example, as shown in Fig. 1, the third bypass capacitor 40 is connected to the end 22a of the second spring structure via the conductive wire 41, and is connected to the housing 6 via the conductive wire 42. Since the housing 6 is at ground potential, the other electrode terminal of the third bypass capacitor 40 is grounded. Note that the conductive wire 41 and the conductive wire 42 may be lead wires of the third bypass capacitor 40.
[0020] A first bypass capacitor 24 has parasitic inductance that causes electromagnetic noise. Further, in the connector 2, negative inductance is formed by magnetic coupling between a first spring structure 21 and a second spring structure 22. That is, the first spring structure 21 and the second spring structure 22 have a pair of parasitic inductances that cause mutual induction through magnetic coupling. The aforementioned parasitic inductances generated in the first spring structure 21 and the second spring structure 22 cancel out the parasitic inductance generated in the first bypass capacitor 24.
[0021] FIG. 2 is a circuit diagram schematically showing a main part of an equivalent circuit of the connector 2. The T-shaped portion constituting the equivalent circuit shown in FIG. 2 is an equivalent circuit of a mutual induction circuit including a parasitic inductor generated in the first spring structure 21 and a parasitic inductor generated in the second spring structure 22. In this portion, when current flows into the parasitic inductor generated in the first spring structure 21 and current flows into the parasitic inductor generated in the second spring structure 22, a mutual inductance -M is formed between the two parasitic inductors.
[0022] The equivalent circuit shown in FIG. 2 is an equivalent circuit composed of three inductors 101, 102, and 103 having inductances L1+M, L2+M, and -M, and is referred to as a T-type equivalent circuit. The magnitude M of the mutual inductance between the first spring structure 21 and the second spring structure 22 can be expressed by the following formula (1), where N1 is the number of turns of the first spring structure 21, N2 is the number of turns of the second spring structure 22, S2 is the cross-sectional area of the second spring structure 22, and μ0 is the permeability of vacuum. M=μ0×N1×N2×S2 (1)
[0023] Furthermore, the equivalent circuit shown in Figure 2 includes the T-type equivalent circuit described above, a first bypass capacitor 24, and a parasitic inductor 104 in the wiring inductance L3. In Figure 2, the equivalent inductance of inductor 101 is L1+M, and the equivalent inductance of inductor 102 is L2+M. The first bypass capacitor 24 has a capacitor component 24a with capacitance C and a parasitic inductor 24b having a residual inductance Lp which is the equivalent series inductance (ESL). The parasitic inductor 104 is formed by the conductors 25 and 26 shown in Figure 1.
[0024] Connector 2 has a bypass circuit including a conductor 25 and a first bypass capacitor 24. In this bypass circuit, an inductor 103 with negative inductance -M appears equivalently, as shown in Figure 2, due to the magnetic coupling of the first spring structure 21 and the second spring structure 22. That is, inductor 103 is equivalently connected to the series connection point Np between inductors 101 and 102. Furthermore, the bypass circuit consists of an inductor 103 with negative inductance -M, a capacitor component 24a, and a parasitic inductor 24b connected in series.
[0025] The wiring inductance L3 can be approximately calculated based on the dimensions (e.g., length and conductor diameter) of the conductors 25 and 26. The residual inductance Lp can be calculated by measuring the characteristics of the first bypass capacitor 24.
[0026] In connector 2, the negative inductance -M is designed so that the impedances of the negative inductance -M, the wiring inductance L3, and the residual inductance Lp of the first bypass capacitor 24 cancel each other out. As a result, the impedance of the bypass circuit becomes equivalent to the impedance of only the capacitor component 24a, and using equation (1) above, it is possible to design the circuit so that the negative inductance -M has an optimal value.
[0027] Figure 3 is a schematic circuit diagram showing the equivalent circuit of connector 2. The equivalent circuit shown in Figure 3 includes the equivalent circuit shown in Figure 2, a second bypass capacitor 30, a third bypass capacitor 40, a noise source 200, the impedance 201 of the noise source 200, and the impedance 202 of the load. In the following explanation, the impedance 201 of the noise source 200 will be referred to as the noise source impedance 201, and the impedance 202 of the load will be referred to as the load impedance 202. Furthermore, the left side of the second bypass capacitor 30, which has a noise source 200 and a noise source impedance 201, will be called the noise source side, and the right side of the third bypass capacitor 40, which has a load impedance 202, will be called the load side. Furthermore, the connector 2 shown in Figure 1, with the second bypass capacitor 30 and the third bypass capacitor 40 removed, is called a comparison connector. The role of connector 2 is to reduce the noise generated at noise source 200 and reduce the noise propagating to load impedance 202.
[0028] The extent to which noise propagating to the load impedance 202 can be reduced depends on the relative magnitudes of the noise source impedance 201, the impedance of the second bypass capacitor 30, and the impedance of the inductor 102. If the noise source impedance 201 is several hundred ohms, which is sufficiently higher than the impedance of the second bypass capacitor 30, then connector 2 can suppress electromagnetic noise more effectively than the comparison connector.
[0029] When an inductor and a bypass capacitor are used as a noise filter, and the noise source impedance 201 is sufficiently high at several hundred ohms, the equivalent circuit shown in Figure 3, in connector 2, with a shunt bypass capacitor, followed by a series inductor, and then another shunt bypass capacitor, acts as an effective noise filter. In other words, in connector 2, the low impedance of the parallel connections formed by the second bypass capacitor 30, the first bypass capacitor 24, and the third bypass capacitor 40 is located next to the high impedance of the series connections formed by the inductor 102, resulting in high filtering performance.
[0030] On the other hand, when the noise source impedance 201 is low, the equivalent circuit shown in Figure 2, in which there is a series inductor, followed by a shunt bypass capacitor (first bypass capacitor 24), and then another series inductor, acts as a noise filter in connector 2. In the equivalent circuit shown in Figure 2, the negative inductance formed by the magnetic coupling between the first spring structure 21 and the second spring structure 22 cancels out the parasitic inductance generated in the bypass circuit including the first bypass capacitor 24, thereby suppressing electromagnetic noise.
[0031] Although Figure 1 shows a connector 2 equipped with both a second bypass capacitor 30 and a third bypass capacitor 40, the connector 2 may be equipped with either the second bypass capacitor 30 or the third bypass capacitor 40. For example, connector 2 may consist only of a second bypass capacitor 30 in addition to the first spring structure 21, the second spring structure 22, the conductor 23, and the first bypass capacitor 24. When the noise source impedance 201 or the load impedance 202 is sufficiently high, the low impedance in parallel, provided by the second bypass capacitor 30 and the first bypass capacitor 24, is located next to the high impedance in series, such as the inductor 102, thus improving the filtering performance of connector 2.
[0032] Furthermore, connector 2 may consist only of a third bypass capacitor 40 in addition to the first spring structure 21, the second spring structure 22, the conductor 23, and the first bypass capacitor 24. When the noise source impedance 201 or the load impedance 202 is sufficiently high, the low impedance in parallel, provided by the first bypass capacitor 24 and the third bypass capacitor 40, is located next to the high impedance in series, such as the inductor 102, thus improving the filtering performance of connector 2.
[0033] As described above, the connector 2 according to Embodiment 1 comprises a first spring structure 21 made of a coil-shaped winding with one end 21a connected to the connection part 3, and a second spring structure 22 made of a coil-shaped winding wound in the same direction as the first spring structure 21, with one end 22a connected to the connection part 4a. The first spring structure 21 and the second spring structure 22 have windings that are insulated from each other and arranged alternately along the same direction. Furthermore, the connector 2 includes a conductor 23 that electrically connects the other end 21b of the first spring structure 21 and the other end 22b of the second spring structure 22, a first bypass capacitor 24 with one electrode terminal connected to the first spring structure 21 and the conductor 23 and the other electrode terminal grounded, a second bypass capacitor 30 with one electrode terminal connected to the first spring structure 21 and the other electrode terminal grounded, and a third bypass capacitor 40 with one electrode terminal connected to the second spring structure 22 and the other electrode terminal grounded. By including the second bypass capacitor 30 and the third bypass capacitor 40 in addition to the first bypass capacitor 24, the connector 2 has improved filtering performance, making it possible to suppress electromagnetic noise without providing a separate filter.
[0034] The connector 2 according to Embodiment 1 comprises a first spring structure 21 made of a coil-shaped winding with one end 21a connected to a connection part 3, and a second spring structure 22 made of a coil-shaped winding wound in the same direction as the first spring structure 21, with one end 22a connected to a connection part 4a. The first spring structure 21 and the second spring structure 22 have windings that are insulated from each other and arranged alternately along the same direction. Furthermore, the connector 2 comprises a conductor 23 that electrically connects the other end 21b of the first spring structure 21 and the other end 22b of the second spring structure 22, a first bypass capacitor 24 with one electrode terminal connected to the first spring structure 21 and the conductor 23 and the other electrode terminal grounded, and a second bypass capacitor 30 with one electrode terminal connected to the first spring structure 21 and the other electrode terminal grounded. Connector 2, by including a second bypass capacitor 30 in addition to the first bypass capacitor 24, has improved filtering performance, making it possible to suppress electromagnetic noise without providing a separate filter.
[0035] The connector 2 according to Embodiment 1 comprises a first spring structure 21 made of a coil-shaped winding with one end 21a connected to a connection part 3, and a second spring structure 22 made of a coil-shaped winding wound in the same direction as the first spring structure 21, with one end 22a connected to a connection part 4a. The first spring structure 21 and the second spring structure 22 have windings that are insulated from each other and arranged alternately along the same direction. Furthermore, the connector 2 comprises a conductor 23 that electrically connects the other end 21b of the first spring structure 21 and the other end 22b of the second spring structure 22, a first bypass capacitor 24 with one electrode terminal connected to the first spring structure 21 and the conductor 23 and the other electrode terminal grounded, and a third bypass capacitor 40 with one electrode terminal connected to the second spring structure 22 and the other electrode terminal grounded. Connector 2, by including a third bypass capacitor 40 in addition to the first bypass capacitor 24, has improved filtering performance, making it possible to suppress electromagnetic noise without providing a separate filter.
[0036] The electronic device 1 according to Embodiment 1 comprises a connection part 3, a connection part 4a, and a connector 2. Since the connector 2 suppresses electromagnetic noise without requiring a noise filter on the printed circuit board 5, it is possible to provide an electronic device 1 that can be miniaturized.
[0037] Embodiment 2. Figure 4 is a conceptual diagram schematically showing the configuration of the electronic device 1A according to Embodiment 2. In Figure 4, the electronic device 1A has a structure in which connection part 3 and connection part 4a are connected by a connector 2A according to Embodiment 2. Connection part 3 is a first object electrically connected to the printed circuit board 5. The printed circuit board 5 is provided inside the housing 6 of the electronic device 1A. The housing 6 is at a constant potential, for example, ground potential.
[0038] The connection part 4a is a second object such as an electrode terminal provided on the housing 6 of the electronic device 1A, and a socket 4 is connected to the connection part 4a. The socket 4 is connected to the cable 7. By connecting the socket 4 to the connection part 4a, the connection part 4a is electrically connected to the core wire 8 inside the cable 7. The connector 2A has a function to suppress electromagnetic noise, similar to the connector 2 according to Embodiment 1.
[0039] As shown in Figure 4, connector 2A comprises a magnetic material 9, a first spring structure 21, a second spring structure 22, a conductor 23, a first bypass capacitor 24, a second bypass capacitor 30, and a third bypass capacitor 40. The first spring structure 21 is a spring structure made of a coil-shaped winding, with one end 21a connected to the connection part 3. The second spring structure 22 is a spring structure made of a coil-shaped winding wound in the same direction as the first spring structure 21, with one end 22a connected to the connection part 4a.
[0040] The magnetic material 9 is provided inside the first spring structure 21 and the second spring structure 22, and as shown in Figure 4, it is in contact with the lower parts of the first spring structure 21 and the second spring structure 22. This allows a portion of the magnetic path of the magnetic flux generated between the first spring structure 21 and the second spring structure 22 to be confined inside the magnetic material 9. At this time, as shown by the dashed line in Figure 4, a magnetic path is formed inside the magnetic material 9 through which the magnetic flux MF generated between the first spring structure 21 and the second spring structure 22 passes.
[0041] By placing the magnetic material 9 inside the first spring structure 21 and the second spring structure 22, the magnetic flux MF is concentrated inside the magnetic material 9. This reduces the amount of magnetic flux leaking into the air. As a result, the permeability μ of the magnetic material 9 is given by equation (1) above. r Since this is multiplied, the magnitude of the mutual inductance M becomes even higher. The increased magnitude of the mutual inductance M allows the cross-sectional area or number of turns of the spring structure to be set to a smaller value.
[0042] For example, by placing the magnetic material 9 inside the first spring structure 21 and the second spring structure 22, the length of each winding of the first spring structure 21 and the second spring structure 22 can be shortened. In other words, it is possible to reduce the dimensions of the first spring structure 21 and the second spring structure 22 required to obtain the inductance-M.
[0043] The magnetic material 9 is preferably a ferrite magnetic material that has high magnetic permeability for high-frequency signals of several MHz or higher. For example, a ferrite core in which soft magnetic metal powder is dispersed may be used as the magnetic material 9.
[0044] Although Figure 4 shows a connector 2A equipped with both a second bypass capacitor 30 and a third bypass capacitor 40, the connector 2A may be equipped with either the second bypass capacitor 30 or the third bypass capacitor 40. For example, connector 2A may consist only of a first spring structure 21, a second spring structure 22, a conductor 23, a first bypass capacitor 24, and a second bypass capacitor 30. Alternatively, connector 2A may consist only of a first spring structure 21, a second spring structure 22, a conductor 23, a first bypass capacitor 24, and a third bypass capacitor 40.
[0045] As described above, the connector 2A according to Embodiment 2 includes a magnetic material 9 provided inside the first spring structure 21 and the second spring structure 22. For example, the magnetic material 9 is a ferrite magnetic material. This allows the connector 2A to set the cross-sectional area or number of turns of the first spring structure 21 and the second spring structure 22 to a small value. Furthermore, it is possible to provide an electronic device 1A that can be made smaller than that of Embodiment 1.
[0046] Furthermore, it is possible to combine each embodiment, modify any component of each embodiment, or omit any component in each embodiment. [Industrial applicability]
