Description

Connectors and Electronics

[0001] The present disclosure relates to connectors and electronic devices.

[0002] For example, Patent Document 1 describes a circuit board, a filter circuit, and a capacitance element that can cancel the parasitic inductance of a capacitance element and maintain charge supply performance for electronic components as circuit elements to be mounted on an electronic device. The circuit board is a circuit board on which the capacitance element is mounted, and includes: 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 an area 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 area where the capacitance element is mounted from the 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 that forms a capacitance between the output terminal and the second electrode, wherein the capacitance formed by the output terminal and the second electrode is equal to or greater than the capacitance of the capacitance element. In this way, the circuit board described in Patent Document 1 is equipped with a first inductance element and a second inductance element, and since the capacitance formed by 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, making it possible to maintain the charge supply performance to electronic components.

[0003] International Publication No. 2017 / 110179

[0004] However, the conventional technology described in Patent Document 1 has a problem in that when the impedance of the noise source or the impedance of the load is high, on the order of several hundred ohms, the performance of the circuit board acting as a noise filter is not fully demonstrated, and it is necessary to provide a noise filter separately from the circuit board.

[0005] The present disclosure is devised to solve the above-mentioned problems, and aims to provide a connector that can suppress electromagnetic noise without providing a separate filter, and an electronic device that uses the same.

[0006] The connector according to the present disclosure is a connector for connecting a first object and a second object, and comprises: a first spring structure made of a coil-shaped winding, one end of which is connected to the first object; and a second spring structure made of a coil-shaped winding wound in the same direction as the first spring structure, one end of which is connected to the second object, wherein the first spring structure and the second spring structure have windings insulated from each other and arranged alternately along the same direction; a conductor electrically connecting the other end of the first spring structure to the other end of the second spring structure; a first bypass capacitor having one electrode terminal connected to the first spring structure and the conductor and the other electrode terminal grounded; a second bypass capacitor having one electrode terminal connected to the first spring structure and the other electrode terminal grounded; and a third bypass capacitor having one electrode terminal connected to the second spring structure and the other electrode terminal grounded.

[0007] According to the present disclosure, in addition to a first bypass capacitor having one electrode terminal connected to a first spring structure and a conductor and the other electrode terminal grounded, a second bypass capacitor having one electrode terminal connected to the first spring structure and the other electrode terminal grounded, and a third bypass capacitor having one electrode terminal connected to the second spring structure and the other electrode terminal grounded, are provided. This arrangement ensures that a high series impedance is adjacent to a low parallel impedance, even when the impedance of the noise source or the load is high, on the order of several hundred ohms, thereby improving the filtering performance of the connector according to the present disclosure. In contrast, for example, the circuit board described in Patent Document 1 does not include a second bypass capacitor or a third bypass capacitor. Therefore, when the impedance of the noise source or the load is high, on the order of several hundred ohms, a high series impedance is adjacent to another high series impedance, thereby failing to fully demonstrate the filtering performance of the circuit board. The connector according to the present disclosure ensures that a high series impedance is adjacent to a low parallel impedance, thereby improving the filtering performance of the connector and enabling electromagnetic noise suppression without the need for a separate filter.

[0008] Fig. 1 is a conceptual diagram schematically showing the configuration of an electronic device according to embodiment 1. Fig. 2 is a circuit diagram schematically showing a main part of an equivalent circuit of a connector according to embodiment 1. Fig. 3 is a circuit diagram schematically showing an equivalent circuit of a connector according to embodiment 1. Fig. 4 is a conceptual diagram schematically showing the configuration of an electronic device according to embodiment 2.

[0009] First Embodiment Fig. 1 is a conceptual diagram showing a schematic configuration of an electronic device 1 according to a first embodiment. In Fig. 1, the electronic device 1 has a structure in which a connection portion 3 and a connection portion 4a are connected by a connector 2 according to the first embodiment. The connection portion 3 is a first object electrically connected to a printed circuit board 5. The printed circuit board 5 is provided inside a housing 6 of the electronic device 1. The housing 6 is at a constant potential, for example, a ground potential.

[0010] The connection portion 4a is a second object such as an electrode terminal provided on the housing 6 of the electronic device 1, and the socket 4 is connected to the connection portion 4a. The socket 4 is connected to the cable 7. By connecting the socket 4 to the connection portion 4a, the connection portion 4a is electrically connected to the core wire 8 in the cable 7. By connecting the connection portion 3 and the connection portion 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, the connector 2 has a function of suppressing electromagnetic noise. For example, if the electronic device 1 is a high-frequency communication device, the connector 2 functions as a noise filter that removes electromagnetic noise in the high-frequency band that leaks from the circuit of the printed circuit board 5.

[0012] 1, the connector 2 includes a first spring structure 21, a second spring structure 22, a conductor 23, and a first bypass capacitor 24, as well as 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, one end 21a of which is connected to the connection portion 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, and one end 22a of which is connected to the connection portion 4a.

[0013] The first spring structure 21 and the second spring structure 22 are made of a conductor. In Fig. 1, the first spring structure 21 is shown with a white line and the second spring structure 22 is shown with a black line, but the first spring structure 21 and the second spring structure 22 are made of conductive wires of the same material and dimensions. The first spring structure 21 and the second spring structure 22 have their outer peripheries insulated to prevent direct electrical conduction with each other. For example, non-conductive tape is wrapped around the outer peripheries 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 are aligned (coaxial). Furthermore, as described above, the windings of the first spring structure 21 and the second spring structure 22 are insulated from each other and arranged alternately along the same direction. By arranging them in this manner, 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 corresponding to this mutual inductance. Furthermore, because the windings of the first spring structure 21 and the second spring structure 22 are arranged alternately without being spaced apart at a fixed interval, the magnetic coupling between them is large, and the equivalent negative inductance is also large.

[0015] The first spring structure 21 and the second spring structure 22 have coil shapes wound in the same direction and are connected in series via the conductor 23, so that in the connector 2, current flows in the same direction in the first spring structure 21 and the second spring structure 22. Furthermore, due to parasitic inductance, magnetic fluxes generated inside the first spring structure 21 and the second spring structure 22 also flow in approximately the same direction.

[0016] Conductor 23 electrically connects the other end 21b of first spring structure 21 to the other end 22b of second spring structure 22. First spring structure 21 and second spring structure 22 are indirectly connected by conductive wire 23. In FIG. 1 , conductive wire 23 has a bent portion, but it may also have a linear wiring pattern. Furthermore, conductive wire 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 conductor 23, and the other electrode terminal grounded. For example, as shown in Fig. 1 , the first bypass capacitor 24 is connected to the connection point between the end 21b of the first spring structure 21 and the conductor 23 via a conductor 25, and is connected to the housing 6 via a conductor 26. Since the housing 6 is at ground potential, the other electrode terminal of the first bypass capacitor 24 is grounded. Note that the conductor 25 and the conductor 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 21 a 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 21 a of the first spring structure via a conductor 31 and to the housing 6 via a conductor 32. Since the housing 6 is at ground potential, the other electrode terminal of the second bypass capacitor 30 is grounded. Note that the conductors 31 and 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 a conductor 41 and to the housing 6 via a conductor 42. Since the housing 6 is at ground potential, the other electrode terminal of the third bypass capacitor 40 is grounded. Note that the conductors 41 and 42 may be lead wires of the third bypass capacitor 40.

[0020] The first bypass capacitor 24 generates a parasitic inductance that causes electromagnetic noise. Furthermore, in the connector 2, the first spring structure 21 and the second spring structure 22 are magnetically coupled to each other, resulting in a negative inductance. That is, the first spring structure 21 and the second spring structure 22 have a pair of parasitic inductances that cause mutual induction due to their magnetic coupling. The parasitic inductance generated in the first spring structure 21 and the second spring structure 22 cancels out the parasitic inductance generated in the first bypass capacitor 24.

[0021] Fig. 2 is a circuit diagram that schematically illustrates the main parts of the equivalent circuit of the connector 2. The T-shaped portion that constitutes the equivalent circuit shown in Fig. 2 is an equivalent circuit of a mutual induction circuit that includes 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 a current flows into the parasitic inductor generated in the first spring structure 21 and a 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] 2 is an equivalent circuit consisting of three inductors 101, 102, and 103 having inductances L1+M, L2+M, and −M, and is called a T-type equivalent circuit. The magnitude M of the mutual inductance between the first spring structure 21 and the second spring structure 22 is determined by the number of turns of the first spring structure 21, N. １ and the number of turns of the second spring structure 22 is N ２ and the cross-sectional area of ​​the second spring structure 22 is S ２ Let the magnetic permeability of vacuum be μ ０ In this case, it can be expressed by the following formula (1): M=μ ０ ×N １ ×N ２ ×S ２ (1)

[0023] 2 includes the T-type equivalent circuit described above, the first bypass capacitor 24, and a parasitic inductor 104 in the wiring inductance L3. In FIG. 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 includes a capacitor component 24a with a capacitance C and a parasitic inductor 24b with a residual inductance Lp, which is an equivalent series inductance (ESL). The parasitic inductor 104 is formed by the conductors 25 and 26 shown in FIG. 1.

[0024] The connector 2 has a bypass circuit including a conductor 25 and a first bypass capacitor 24. In this bypass circuit, the first spring structure 21 and the second spring structure 22 are magnetically coupled, and as shown in FIG. 2, an inductor 103 having a negative inductance -M appears equivalently. That is, the inductor 103 is equivalently connected to the series connection point Np between the inductors 101 and 102. In addition, the inductor 103 having a negative inductance -M, the capacitor component 24a, and the parasitic inductor 24b are connected in series in the bypass circuit.

[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 the 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. This makes the impedance of the bypass circuit equivalent to the impedance of only the capacitor component 24a, so that the negative inductance -M can be designed to have an optimal value using the above formula (1).

[0027] FIG. 3 is a schematic circuit diagram illustrating an equivalent circuit of the connector 2. The equivalent circuit shown in FIG. 3 includes the equivalent circuit shown in FIG. 2 , a second bypass capacitor 30, a third bypass capacitor 40, a noise source 200, an impedance 201 of the noise source 200, and a load impedance 202. In the following description, the impedance 201 of the noise source 200 is referred to as the noise source impedance 201, and the load impedance 202 is referred to as the load impedance 202. Furthermore, the left side of the second bypass capacitor 30, where the noise source 200 and the noise source impedance 201 are located, is referred to as the noise source side, and the right side of the third bypass capacitor 40, where the load impedance 202 is located, is referred to as the load side. The connector 2 shown in FIG. 1 , with the second bypass capacitor 30 and the third bypass capacitor 40 removed, is referred to as a comparative connector. The role of the connector 2 is to reduce noise generated by the noise source 200 and to reduce noise propagating to the load impedance 202.

[0028] The extent to which noise propagating to load impedance 202 can be reduced depends on the magnitude relationship between noise source impedance 201, the impedance of second bypass capacitor 30, and the impedance of inductor 102. When noise source impedance 201 is on the order of several hundred ohms, which is sufficiently higher than the impedance of second bypass capacitor 30, connector 2 can suppress electromagnetic noise better than the comparative connector.

[0029] When an inductor and a bypass capacitor are used as a noise filter and noise source impedance 201 is sufficiently high at around several hundred ohms, the equivalent circuit shown in Figure 3, in which, from the side closest to noise source 200, there is a shunt bypass capacitor, then a series inductor, and then another shunt bypass capacitor, is effective as a noise filter. In other words, in connector 2, there is an arrangement in which a low parallel impedance consisting of second bypass capacitor 30, first bypass capacitor 24, and third bypass capacitor 40 is present next to a high series impedance such as inductor 102, thereby improving filter performance.

[0030] On the other hand, when noise source impedance 201 is low, the equivalent circuit shown in Fig. 2, in which, from the side closest to noise source 200, there is a series inductor, then a shunt bypass capacitor (first bypass capacitor 24), and then a series inductor, is arranged, is effective as a noise filter in connector 2. In the equivalent circuit shown in Fig. 2, the negative inductance formed by the magnetic coupling between first spring structure 21 and second spring structure 22 cancels out the parasitic inductance generated in the bypass circuit including first bypass capacitor 24, thereby making it possible to suppress electromagnetic noise.

[0031] 1 shows the connector 2 including both the second bypass capacitor 30 and the third bypass capacitor 40, the connector 2 may include either the second bypass capacitor 30 or the third bypass capacitor 40. For example, the connector 2 may include only the 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, a low parallel impedance formed by the second bypass capacitor 30 and the first bypass capacitor 24 is present next to a high series impedance such as the inductor 102, thereby improving the filter performance of the connector 2.

[0032] Furthermore, the connector 2 may include only the 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, a low parallel impedance formed by the first bypass capacitor 24 and the third bypass capacitor 40 exists next to a high series impedance such as the inductor 102, thereby improving the filtering performance of the connector 2.

[0033] As described above, connector 2 according to embodiment 1 includes first spring structure 21 made of a coil-shaped winding, one end 21a of which is connected to connection portion 3, and second spring structure 22 made of a coil-shaped winding wound in the same direction as first spring structure 21, one end 22a of which is connected to connection portion 4a. Each winding of first spring structure 21 and second spring structure 22 is insulated from each other and arranged alternately along the same direction. The connector 2 further includes a conductor 23 electrically connecting the other end 21 b of the first spring structure 21 and the other end 22 b of the second spring structure 22, a first bypass capacitor 24 having 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 having one electrode terminal connected to the first spring structure 21 and the other electrode terminal grounded, and a third bypass capacitor 40 having 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 filter performance, making it possible to suppress electromagnetic noise without providing a separate filter.

[0034] The connector 2 according to the first embodiment includes a first spring structure 21 made of a coil-shaped winding, one end 21a of which is connected to the connection portion 3, and a second spring structure 22 made of a coil-shaped winding wound in the same direction as the first spring structure 21, one end 22a of which is connected to the connection portion 4a. The first spring structure 21 and the second spring structure 22 have windings insulated from each other and arranged alternately along the same direction. The connector 2 further includes a conductor 23 electrically connecting the other end 21b of the first spring structure 21 to the other end 22b of the second spring structure 22, a first bypass capacitor 24 having 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 having one electrode terminal connected to the first spring structure 21 and the other electrode terminal grounded. By providing the second bypass capacitor 30 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.

[0035] The connector 2 according to the first embodiment includes a first spring structure 21 made of a coil-shaped winding, one end 21a of which is connected to the connection portion 3, and a second spring structure 22 made of a coil-shaped winding wound in the same direction as the first spring structure 21, one end 22a of which is connected to the connection portion 4a. The first spring structure 21 and the second spring structure 22 have windings insulated from each other and arranged alternately along the same direction. The connector 2 further includes a conductor 23 electrically connecting the other end 21b of the first spring structure 21 to the other end 22b of the second spring structure 22, a first bypass capacitor 24 having 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 having one electrode terminal connected to the second spring structure 22 and the other electrode terminal grounded. By providing the third bypass capacitor 40 in addition to the first bypass capacitor 24, the connector 2 has improved filter performance, making it possible to suppress electromagnetic noise without providing a separate filter.

[0036] The electronic device 1 according to the first embodiment includes a connection portion 3, a connection portion 4a, and a connector 2. The connector 2 suppresses electromagnetic noise without providing a noise filter on the printed circuit board 5, so that the electronic device 1 can be made smaller.

[0037] Second Embodiment Fig. 4 is a conceptual diagram showing a schematic configuration of an electronic device 1A according to a second embodiment. In Fig. 4, the electronic device 1A has a structure in which a connection portion 3 and a connection portion 4a are connected by a connector 2A according to the second embodiment. The connection portion 3 is a first object electrically connected to a printed circuit board 5. The printed circuit board 5 is provided inside a housing 6 of the electronic device 1A. The housing 6 is at a constant potential, for example, a ground potential.

[0038] The connection portion 4a is a second object such as an electrode terminal provided on the housing 6 of the electronic device 1A, and the socket 4 is connected to the connection portion 4a. The socket 4 is connected to the cable 7. By connecting the socket 4 to the connection portion 4a, the connection portion 4a is electrically connected to the core wire 8 in the cable 7. The connector 2A has the function of suppressing electromagnetic noise, similar to the connector 2 according to the first embodiment.

[0039] 4, the connector 2A includes a magnetic body 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, one end 21a of which is connected to the connection portion 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, one end 22a of which is connected to the connection portion 4a.

[0040] The magnetic body 9 is provided inside the first spring structure 21 and the second spring structure 22, and is in contact with the lower parts of the first spring structure 21 and the second spring structure 22, as shown in Fig. 4. This allows a part 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 body 9. At this time, as shown by the dashed line in Fig. 4, a magnetic path is formed inside the magnetic body 9 through which the magnetic flux MF generated between the first spring structure 21 and the second spring structure 22 passes.

[0041] By arranging the magnetic body 9 inside the first spring structure 21 and the second spring structure 22, the magnetic flux MF is concentrated inside the magnetic body 9. This reduces the amount of magnetic flux leaking into the air. As a result, the magnetic permeability μ of the magnetic body 9 in relation to the above formula (1) is ｒ Since the magnitude of mutual inductance M is increased, the cross-sectional area or the number of turns of the spring structure can be set to a smaller value.

[0042] For example, by arranging the magnetic body 9 inside the first spring structure 21 and the second spring structure 22, it is possible to shorten the length of each winding of the first spring structure 21 and the second spring structure 22. 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] A ferrite magnetic material having high magnetic permeability for high frequency signals of several MHz or more is preferable for the magnetic material 9. For example, a ferrite core in which soft magnetic metal powder is dispersed may be used as the magnetic material 9.

[0044] 4 shows the connector 2A including both the second bypass capacitor 30 and the third bypass capacitor 40, the connector 2A may include either the second bypass capacitor 30 or the third bypass capacitor 40. For example, the connector 2A may include only the second bypass capacitor 30 in addition to the first spring structure 21, the second spring structure 22, the conducting wire 23, and the first bypass capacitor 24. Alternatively, the connector 2A may include only the third bypass capacitor 40 in addition to the first spring structure 21, the second spring structure 22, the conducting wire 23, and the first bypass capacitor 24.

[0045] As described above, the connector 2A according to the second embodiment includes the magnetic body 9 provided inside the first spring structure 21 and the second spring structure 22. For example, the magnetic body 9 is a ferrite magnetic body. This allows the cross-sectional area or the number of turns of the first spring structure 21 and the second spring structure 22 to be set to a small value in the connector 2A. Furthermore, it is possible to provide an electronic device 1A that can be made smaller than that of the first embodiment.

[0046] It is possible to combine the embodiments, modify any of the components of the embodiments, or omit any of the components of the embodiments.

[0047] A connector according to the present disclosure can be used in, for example, a high-frequency communication device.
