Embodiments for Carrying Out the Invention

[0011] Hereinafter, each embodiment according to the present disclosure will be described with reference to the drawings. Note that the drawings and specific configurations used in each embodiment shall not be used for interpreting the disclosure. The same or corresponding configurations in all the drawings are denoted by the same reference numerals, and common descriptions are omitted. Note that in the present disclosure, the drawings are associated with one or more embodiments.

[0012] <First Embodiment> Hereinafter, one embodiment according to the present disclosure will be described with reference to the drawings. Hereinafter, an example of the configuration of a connection member in the present disclosure will be described with reference to FIGS. 1 to 13.

[0013] Hereinafter, the direction in which the support surface 60s of the support portion 60 faces is referred to as the Z direction. The direction in which the second shield case 52 is arranged with respect to the first shield case 51, intersecting the Z direction, is referred to as the X direction. Also, the direction intersecting the Z direction and the X direction is referred to as the Y direction. Further, one direction in the X direction is the +X direction, and the other direction in the X direction is the -X direction. Also, one direction in the Y direction is the +Y direction, and the other direction in the Y direction is the -Y direction. Also, one direction in the Z direction is the +Z direction, and the other direction in the Z direction is the -Z direction.

[0014] For example, the X direction, the Y direction, and the Z direction may be directions orthogonal to each other. For example, the substrate surface 1s of the substrate 1 may be a surface along the XY plane and facing the +Z direction.

[0015] The above expressions are for convenience of explanation and do not limit the direction in which the support surface 60s presses the plurality of shield cases 5 (the first shield case 51 and the second shield case 52).

[0016] (Configuration of the connection structure 100) The connection structure 100 is used to suppress electromagnetic waves that enter the transmission lines provided on the substrate 1 (the first substrate 11 and the second substrate 12). As shown in FIG. 1, the connection structure 100 includes a substrate 1 (the first substrate 11 and the second substrate 12), a line connection conductor 2, a base member 3, a plurality of shield cases 5 (the first shield case 51 and the second shield case 52), and a connection member 6.

[0017] (Configuration of the substrate) As shown in FIG. 2, the substrate 1 includes a first substrate 11 and a second substrate 12. The substrate 1 has a substrate surface 1s on which the connection member 6 is placed. For example, in the present disclosure, the substrate 1 includes a plurality of substrates. The substrate surface 1s in the present disclosure includes a first substrate surface 11s and a second substrate surface 12s. The first substrate surface 11s and the second substrate surface 12s may be located on different planes from each other. Also, the first substrate surface 11s and the second substrate surface 12s may be integrally formed. A ground potential line is patterned on the back surface 1bs of the substrate surface 1s. The substrate 1 has a plurality of through holes. The through holes are electrically connected to a ground potential line provided on the back surface 1bs. Each through hole is provided on the contact surface with the base member 3, the shield case 5, and the connecting member 6. In this disclosure, the through holes are omitted for clarity in the figures.

[0018] (Configuration of the first circuit board) The first substrate 11 has a transmission line 110 for transmitting microwaves or millimeter waves. The first substrate 11 has a first substrate surface 11s on which the connecting member 6 is placed. The first substrate surface 11s is an example of a substrate surface 1s. The transmission line 110 is provided on the first substrate surface 11s. The first substrate 11 has through holes. As described above, the through holes are provided on the contact surfaces with the base member 3, the shield case 5, and the connecting member 6. The base member 3 is in contact with the back surface 1bs of the substrate surface 1s, and the first shield case 51 is in contact with the first substrate surface 11s. The first substrate 11 electrically connects the base member 3 to the ground potential line through contact with the through holes provided on the contact surface with the base member 3. The first substrate 11 electrically connects the first shield case 51 to the ground potential line through contact with the through holes provided on the contact surface with the first shield case 51. Since the first shield case 51 is connected to the ground potential through contact with the through holes, the creepage distance tends to be short. The first substrate 11 electrically connects the connecting member 6 to the ground potential line through contact with the through holes provided on the contact surface with the connecting member 6. Since the connecting member 6 is connected to the ground potential through contact with the through holes, the creepage distance tends to be short. The first substrate 11 has an insertion hole 11h through which the fastening member 81 can be inserted, and an insertion hole 13h through which the fastening member 83 can be inserted.

[0019] (Configuration of the second circuit board) The second substrate 12 has a transmission line 120 for transmitting microwaves or millimeter waves. The second substrate 12 has a second substrate surface 12s on which the connecting member 6 is placed. The second substrate surface 12s is an example of the substrate surface 1s. The transmission line 120 is provided on the second substrate surface 12s. The second substrate 12 has through holes. As described above, the through holes are provided on the contact surfaces with the base member 3, the shield case 5, and the connecting member 6. The base member 3 is in contact with the back surface 1bs of the substrate surface 1s, and the second shield case 52 is in contact with the second substrate surface 12s. The second substrate 12 electrically connects the base member 3 to the ground potential line through contact with the through holes provided on the contact surface with the base member 3. The second substrate 12 electrically connects the second shield case 52 to the ground potential line through contact with the through holes provided on the contact surface with the second shield case 52. Since the second shield case 52 is connected to the ground potential through contact with the through holes, the creepage distance tends to be short. The second substrate 12 electrically connects the connecting member 6 to the ground potential line through contact with the through holes provided on the contact surface with the connecting member 6. Since the connecting member 6 is connected to the ground potential through contact with the through holes, the creepage distance tends to be short. The second substrate 12 has an insertion hole 12h through which the fastening member 82 can be inserted.

[0020] As shown in Figure 2, the line connecting conductor 2 connects the transmission line 110 of the first substrate 11 and the transmission line 120 of the second substrate 12. For example, the line connecting conductor 2 is a conductive wire, a conductive ribbon, etc., and is conductive. When the substrate 1 includes multiple substrates (first substrate 11, second substrate 12), the line connecting conductor 2 suppresses the breakage of the transmission line. Breakage of the transmission line can occur when each substrate undergoes thermal expansion.

[0021] In the connection structure 100 of this disclosure, microwaves or millimeter waves input to the substrate 1 are transmitted from the transmission line 110 (transmission line 120) to the transmission line 120 (transmission line 110) via the line connection conductor 2.

[0022] (Configuration of base components) As shown in Figure 2, the base member 3 holds the substrate 1. In this case, the base member 3 covers the transmission line provided on the first substrate 11 from the back side 1bs. The base member 3 also covers the transmission line provided on the second substrate 12 from the back side 1bs. Furthermore, the base member 3 covers the line connector 2 from the back side 1bs. The base member 3 is made of metal. By connecting the base member 3 to ground potential, the base member 3 suppresses electromagnetic waves entering the transmission line. As described above, the base member 3 is in contact with the back surface 1bs (back surface 11bs, back surface 12bs) of the substrate surface 1s.

[0023] As shown in Figures 1 and 2, the base member 3 has through holes (through holes 31h and 32h) through which fastening members (fastening members 81 and 82), such as screws or bolts, can be inserted. The through holes are provided with threaded portions. For example, in this disclosure, when fastening member 81 is fastened, the first shield case 51 sandwiches the substrate 1 (first substrate 11) together with the base member 3. When fastening member 82 is fastened, the second shield case 52 sandwiches the substrate 1 (second substrate 12) together with the base member 3. As these fastened states are maintained, the potential of the base member 3 is kept at ground potential. At that time, the potentials of the first shield case 51 and the second shield case 52 are kept at ground potential.

[0024] As shown in Figures 1 and 3, the base member 3 has an insertion hole 33h through which a fastening member 83, such as a screw or bolt, can be inserted. The insertion hole is provided with a threaded portion. For example, in this disclosure, when the fastening member 83 is fastened, the fastening member 83, together with the base member 3, sandwiches the substrate 1. As the fastened state is maintained, the potential of the connecting member 6 is maintained at ground potential.

[0025] (Shield case configuration) The shield case 5 covers each transmission line provided on the substrate 1. For example, in the connection structure 100 of this disclosure, two shield cases 5 cover the transmission line 110 and the transmission line 120, respectively. The shield case 5 has an opening in the -Z direction and is placed on the substrate surface 1s. In this case, the shield case 5 covers the transmission line provided on the substrate 1 from the substrate surface 1s side. The shield case 5 is made of metal. By connecting the shield case 5 to ground potential, the shield case 5 suppresses electromagnetic waves entering the transmission line. The first shield case 51 is an example of shield case 5. The second shield case 52 is an example of shield case 5. The first shield case 51 is placed on the first substrate surface 11s. The second shield case 52 is placed on the second substrate surface 12s. The second shield case 52 is aligned with respect to the first shield case 51 in the second direction (X direction).

[0026] Figure 5 shows a cross-sectional view at the cutting line AA, based on the assembled state of the connection structure 100 shown in Figure 4. The first shield case 51 has a first opening 51EX on the surface 51R facing the second shield case 52. As shown in Figures 5 and 6, the first opening 51EX follows the outer shape of the support portion 60, first side wall portion 61, second side wall portion 62, first extension portion 63, and second extension portion 64 provided by the connecting member 6. The second shield case 52 has a second opening 52EX on the surface 52L facing the first shield case 51. The shape of the second opening 52EX is the same as the shape of the first opening 51EX.

[0027] (Configuration of connecting members) The connecting member 6 electrically connects multiple shield cases 5 (first shield case 51, second shield case 52) mounted on the substrate. As shown in Figures 5 and 6, the connecting member 6 covers the line connection conductor 2 from the substrate surface 1s side. The connecting member 6 is made of metal. By connecting the connecting member 6 to ground potential, the connecting member 6 suppresses electromagnetic waves entering the line connection conductor 2. As shown in Figure 7, the connecting member 6 comprises a support portion 60, a first side wall portion 61, a second side wall portion 62, a first extension portion 63, a first bent portion 63b, a second extension portion 64, and a second bent portion 64b.

[0028] The support portion 60 has a support surface 60s facing a first direction. The support surface 60s is biased to press against the multiple shield cases 5 (first shield case 51, second shield case 52) from the first direction (Z direction). Here, the positional relationship between the connecting member 6 and the multiple shield cases 5 (first shield case 51, second shield case 52) is as follows: When viewed from the first direction (Z direction), the first shield case 51 overlaps one side of the support portion 60, and the second shield case 52 overlaps the other side of the support portion 60. In this disclosure, the first shield case 51 overlaps the first end portion 60e1 described later, and the second shield case 52 overlaps the second end portion 60e2 described later. The support portion 60 has a bend line on the support surface 60s. For example, in this disclosure, there is one bend line on the -X side and one bend line on the +X side. The first end portion 60e1, which is one end of the support portion 60, is pivotable in the first direction (Z direction) with respect to the bend line as the pivot axis. The second end portion 60e2, which is one end of the support portion 60, is pivotable in the first direction (Z direction) with respect to the bend line as the pivot axis. By oscillating with the bent line as the pivot axis, the support portion 60 (first end 60e1, second end 60e2) presses against the multiple shield cases 5 (first shield case 51, second shield case 52) from the first direction (Z direction).

[0029] The first side wall portion 61 is erected from the support portion 60 along the first direction. The second side wall portion 62 is erected from the support portion 60 along the first direction. The second side wall portion 62 is aligned with the first side wall portion in the third direction (Y direction). As described above, since the connecting member 6 covers the line connection conductor 2 from the substrate surface 1s side, the second side wall portion 62 faces the first side wall portion 61 with the line connection conductor 2 in between.

[0030] The first extension portion 63 is connected to the first side wall portion 61 and extends along the second direction (X direction). The first extension portion 63 has an insertion hole 63h through which the fastening member 83 can be inserted. The second extension portion 64 connects to the second side wall portion 62 and extends along the second direction (X direction). The second extension portion 64 has an insertion hole 64h through which the fastening member 83 can be inserted.

[0031] The first bent portion 63b is aligned continuously with respect to the first extended portion 63 in the second direction (X direction). The first bent portion 63b has a first contact surface 63bs that can contact the shield case 5, and has a bend line on the first contact surface 63bs. The connecting member 6 is connected to the ground potential by contact with a through hole provided on the contact surface between the substrate 1 and the first extended portion 63. The second bent portion 64b is aligned continuously with respect to the second extended portion 64 in the second direction (X direction). The second bent portion 64b has a second contact surface 64bs that can contact the shield case 5, and has a bend line on the second contact surface 64bs. The connecting member 6 is connected to ground potential by contact with a through hole provided on the contact surface between the substrate 1 and the second extended portion 64.

[0032] Figure 8 shows a cross-sectional view at the cutting line BB, based on the assembled state of the connection structure 100 shown in Figure 4. As shown in Figures 8-11, the second end portion 60e2, which is the other end portion of the support portion 60, contacts the second shield case 52 around the second opening 52EX. The second end portion 60e2 presses the second shield case 52 from the first direction (Z direction), with the bend line as the axis of rotation. Similarly, the first end portion 60e1, which is one of the support portions, contacts the first shield case 51 around the first opening 51EX. The first end portion 60e1 presses the first shield case 51 from the first direction (Z direction) with the bend line as the axis of rotation.

[0033] Furthermore, as shown in Figures 10 and 11, the first bent portion 63b presses the second shield case 52 from the first direction (Z direction) with its first contact surface 63bs. The second bent portion 64b presses the second shield case 52 from the first direction (Z direction) with the second contact surface 64bs.

[0034] As shown in Figure 12, the first shield case 51 has a contact surface around the first opening 51EX that corresponds to the connecting member 6. The first end portion 60e1 of the support portion 60 makes contact with the contact surface 51cs1. The second shield case 52 has contact surfaces around the second opening 52EX that correspond to the connecting member 6. The second end portion 60e2 of the support portion 60 contacts the contact surface 52cs1. The first bent portion 63b contacts the contact surface 52cs2. The second bent portion 64b contacts the contact surface 52cs3.

[0035] Figure 13 shows the positional relationship between the connecting member 6 and the line connecting conductor 2. When constructing a 50Ω transmission line, the dimensions of the line connection conductor 2 and the above positional relationship are determined by the following formula. Z = 188.31 / (2c / ε + d2 / h + d1 / g) Z = Impedance (50Ω) ε = permittivity (of air) c: The shortest distance from the connection point between the second side wall portion 62 and the second extension portion 64 to the track connecting conductor 2. distance from the second side wall portion 62 to the track connecting conductor 2 in the h:Y direction. g: Distance to the line connecting conductor 2 in the Z direction, relative to the plane of the second extension portion 64 (first extension portion 63) facing the -Z direction. d1: Dimensional value (thickness dimension) of the track connection conductor 2 in the Z direction. d2: Dimensional value (width dimension) of the track connection conductor 2 in the Y direction. In relation to the above equation, the distance from the second side wall portion 62 to the first side wall portion 61 in the Y direction is 2g + d2. Regarding the above equation, the distance from the second extension portion 64 to the support portion 60, with reference to the surface of the second extension portion 64 facing the -Z direction, in the Z direction is 2h + d1.

[0036] (Method of connecting transmission lines) An example of a transmission line connection method in this disclosure will be explained below with reference to Figure 14.

[0037] First, the worker prepares a connecting member whose support surface is biased to press against multiple shield cases from a first direction (Step ST10: Step of preparing the connecting member).

[0038] The connecting member used in the method of connecting transmission lines includes a support portion 60 having a support surface 60s facing a first direction, and the support surface 60s is biased to press against a plurality of shield cases 5 from the first direction.

[0039] Next, the worker places the connecting member onto the circuit board (Step ST11: Step of placing the connecting member).

[0040] Next, the worker places multiple shield cases onto the circuit board (Step ST12: Step of placing multiple shield cases). Here, the potentials between multiple shield cases are matched by the connecting member. (Complete)

[0041] (Mechanism of Action and Effects) The connecting member 6 in this embodiment includes a support portion 60 having a support surface 60s facing a first direction, and the support surface 60s is biased to press against the multiple shield cases 5 (first shield case 51, second shield case 52) from the first direction (Z direction). By biasing the support portion 60, the connecting member 6 can easily come into contact with the multiple shield cases 5, enabling electrical connection between the multiple shield cases placed on the substrate. Therefore, the connecting member according to this disclosure facilitates matching the potential between multiple shield cases.

[0042] In addition, the connecting member 6 of this disclosure also has the effect that, because "the connecting member 6 is made of metal," "the support portion 60 is more likely to have a bend line on the support surface 60s."

[0043] In addition, the connecting member 6 of this disclosure further has the effect that "the support portion 60 has a bend line on the support surface 60s," which allows "the connecting member 6 to easily come into contact with multiple shield cases 5 even when the sizes of the multiple shield cases 5 are different."

[0044] In addition, the connecting member 6 of this disclosure has the further advantage that "one end of the support portion 60 can swing in the first direction with the bend line as the pivot axis," which allows "the connecting member 6 to make better contact with the multiple shield cases 5 even when the sizes of the multiple shield cases 5 differ."

[0045] Furthermore, the transmission line connection structure of this disclosure includes "the above-mentioned connection member 6, a substrate 1 having a substrate surface 1s on which the connection member 6 is placed, a shield case 5 comprising a first shield case 51 placed on the substrate surface 1s, and a second shield case 52 placed on the substrate surface 1s, wherein the second shield case 52 is arranged in a second direction (X direction) intersecting the first direction with respect to the first shield case 51, the first shield case 51 has a first opening 51EX on a surface 51R facing the second shield case 52, the second shield case 52 has a second opening 52EX on a surface 52L facing the first shield case 51, one of the support portion 60 contacts the first shield case 51 around the first opening 51EX, and the other of the support portion 60 contacts the second shield case 52 around the second opening 52EX," thereby providing the following effects. In the transmission line connection structure of this disclosure, the support portion 60 is biased, making it easier for the connecting member 6 to come into contact with the multiple shield cases 5, thereby enabling electrical connection between the multiple shield cases mounted on the substrate. Therefore, the connection structure of the transmission line makes it easy to match the potential between multiple shield cases.

[0046] Furthermore, the transmission line connection structure of this disclosure provides the effect that, "when viewed from the first direction (Z direction), the first shield case 51 overlaps one of the support portion 60, and the second shield case 52 overlaps the other of the support portion 60," thereby "making it easier for the connecting member 6 to come into contact with the multiple shield cases 5 (first shield case 51 and second shield case 52)."

[0047] Furthermore, the transmission line connection structure of this disclosure includes a first substrate and a second substrate, and comprises a line connection conductor 2 that connects the transmission line 110 of the first substrate 11 and the transmission line 120 of the second substrate 12, and the connection member 6 further comprises a first side wall portion 61 erected from the support portion 60 along a first direction, and a second side wall portion 62 erected from the support portion 60 along a first direction and aligned with the first side wall portion 61 in a third direction, the third direction (Y direction) intersects the first and second directions, and the second side wall portion 62 faces the first side wall portion 61 with the line connection conductor 2 in between, thereby having the following effects. Since the connecting member 6 can electrically connect multiple shield cases 5, the potential of the connecting member 6 becomes equal to that of the multiple shield cases 5. Because the connecting member 6 covers a portion of the line connection conductor 2, the connecting member 6 can easily suppress electromagnetic waves entering the line connection conductor 2.

[0048] Furthermore, in the transmission line connection structure of this disclosure, the connection member 6 further comprises a first extension portion 63 connected to the first side wall portion 61 and extending along the second direction (X direction), a first bent portion 63b continuously aligned with the first extension portion 63 in the second direction, a second extension portion 64 connected to the second side wall portion 62 and extending along the second direction, and a second bent portion 64b continuously aligned with the second extension portion 64 in the second direction, wherein the first bent portion 63b biases the second shield case 52 from the first direction (Z direction), and the second bent portion 64b biases the second shield case 52 from the first direction, thereby providing the effect that the connection member 6 can easily contact the second shield case 52.

[0049] Furthermore, the transmission line connection structure of this disclosure also provides the effect that "the potential of the multiple shield cases 5 becomes equal to the potential of the ground potential line provided on the back surface 1bs," by "further comprising a base member 3 that contacts the back surface 1bs of the substrate surface 1s, the substrate 1 having a plurality of through holes, the base member 3 being electrically connected to a ground potential line provided on the back surface 1bs by contact with each through hole, and each shield case being electrically connected to a ground potential line provided on the back surface 1bs by contact with each through hole."

[0050] (modified version) In one example of this embodiment, the potential of the connecting member 6 was maintained at ground potential by fastening it with the fastening member 83. The first substrate 11 electrically connects the connecting member 6 to the ground potential line by contact with a through hole provided on the contact surface with the connecting member 6, so the method of fixing the connecting member 6 is not limited to fastening with the fastening member 83. For example, the connecting member 6 may be fixed to the substrate 1 by soldering. The potential of the connecting member 6 is also maintained at ground potential by soldering it to the substrate.

[0051] <Second Embodiment> An embodiment of this disclosure will be described below with reference to the figures.

[0052] (composition) As shown in Figure 15, the connecting member 6m is a connecting member that electrically connects a plurality of shield cases placed on a substrate, and comprises a support portion 60m having a support surface 60sm facing a first direction, and the support surface 60sm is biased to press the plurality of shield cases from the first direction.

[0053] (Mechanism of Action and Effects) The connecting member 6m of this disclosure includes a support portion 60m having a support surface 60sm facing a first direction, and the support surface 60sm is biased to press against a plurality of shield cases from the first direction. By biasing the support portion 60m, the connecting member 6m is made more likely to come into contact with the plurality of shield cases, thereby enabling electrical connection between the plurality of shield cases placed on the substrate. Therefore, the connecting member according to this disclosure facilitates matching the potential between multiple shield cases.
