[0022] (Outline of the embodiment) Hereinafter, an embodiment of a coaxial connector with a switch 2 according to the present disclosure and a coaxial connector set 100 including the same (FIG. 11) will be described with reference to the drawings. For convenience, each figure shows an X-axis, a Y-axis, and a Z-axis that are orthogonal to each other. In this specification, the first width direction, the second width direction, and the height direction (thickness direction) of the coaxial connector with a switch 2 are defined as the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively.

[0023] 1 and 2 are perspective views of a coaxial connector 2 with a switch according to one embodiment, FIG. 3 is a plan view of the coaxial connector 2 with a switch, FIG. 4 is a front view of the coaxial connector 2 with a switch, and FIG. 5 is an exploded perspective view of the coaxial connector 2 with a switch.

[0024] As shown in FIGS. 1 to 5, the coaxial connector with a switch 2 includes a first inner terminal 4 (FIG. 1), a second inner terminal 6 (FIG. 2), a holding member 8, and an outer terminal 10.

[0025] The first internal terminal 4 and the second internal terminal 6 are terminals that come into contact with and are electrically connected to each other inside the coaxial connector with switch 2. The electrically connected state of the first internal terminal 4 and the second internal terminal 6 is switched to a non-conductive state when a probe 60 (FIG. 11) of the mating connector (not shown) comes into contact with and presses the second internal terminal 6.

[0026] The electrical characteristics of an RF circuit in a device (e.g., a mobile phone) equipped with the switch-equipped coaxial connector 2 can be inspected by the switching operation that switches the conductive state of the first internal terminal 4 and the second internal terminal 6. The first internal terminal 4 that does not come into direct contact with the probe 60 may be referred to as a "fixed terminal," and the second internal terminal 6 that comes into direct contact with the probe 60 may be referred to as a "movable terminal."

[0027] The first internal terminal 4 and the second internal terminal 6 are both mounted on a substrate (not shown).

[0028] The holding member 8 is a member that holds the first internal terminal 4, the second internal terminal 6 and the external terminal 10, and is made of an electrically insulating material such as resin.

[0029] The external terminal 10 is a terminal (ground terminal) connected to a ground potential, and is provided to suppress electrical interference in the first internal terminal 4 and the second internal terminal 6. The external terminal 10 is disposed so as to cover the holding member 8, and is mounted together with the first internal terminal 4 and the second internal terminal 6 on a substrate (not shown).

[0030] The first internal terminal 4, the second internal terminal 6, and the external terminal 10 are each formed by bending a thin conductive metal plate, and may be made of, for example, stainless steel. Stainless steel is a conductive and elastically deformable material. The surfaces of the first internal terminal 4, the second internal terminal 6, and the external terminal 10 may be gold-plated, for example.

[0031] As shown in Fig. 5, the holding member 8 has a first holding member 8A and a second holding member 8B. The first holding member 8A holds the first internal terminals 4, the second internal terminals 6, and the external terminals 10 as a whole, while the second holding member 8B holds mainly the external terminals 10. The second holding member 8B has a through hole 13 formed therein for inserting a probe 60 (Fig. 11). The first holding member 8A and the second holding member 8B are also simply referred to as "holding members 8A, 8B."

[0032] 1 to 5, the external terminal 10 has a substantially cylindrical tube portion 12. The second holding member 8B shown in Fig. 5 is disposed inside the tube portion 12, and the through hole 13 is exposed.

[0033] 6 and 7 are a perspective view and an exploded perspective view, respectively, showing the first inner terminal 4, the second inner terminal 6, and the holding member 8A.

[0034] As shown in FIGS. 6 and 7, the first inner terminal 4 has a first piece 14, a second piece 16, and a mounting portion 18 (FIG. 7).

[0035] The first piece 14 and the second piece 16 are pieces that come into contact with the second internal terminal 6. Both the first piece 14 and the second piece 16 are free pieces that have the ability to elastically deform. A free piece is a piece that has a free end (open end) that is not fixed at the tip side. In this embodiment, both the first piece 14 and the second piece 16 are located in the +Z direction from the second internal terminal 6 and are arranged so as to cover the second internal terminal 6 from diagonally above.

[0036] Mounting portion 18 is mounted on a substrate (not shown). First piece 14 and second piece 16 have free ends, whereas mounting portion 18 has a fixed end that is mounted and fixed to the substrate.

[0037] The second internal terminal 6 has a contact portion 20, two arm portions 22, 24, a mounting portion 26, and an extending portion .

[0038] The contact portion 20 is a portion that comes into contact with the probe 60, and is pressed in the −Z direction by the probe 60 (arrow A1).

[0039] The arm portions 22 and 24 are portions that come into contact with the first internal terminal 4. The arm portion 22 comes into contact with the first piece 14 of the first internal terminal 4, and the arm portion 24 comes into contact with the second piece 16 of the first internal terminal 4. The arm portions 22 and 24 are each free pieces that have free ends that are not fixed to other members. Both the arm portions 22 and 24 are configured integrally with the contact portion 20, and as the contact portion 20 is deformed by being pressed by the probe 60, the arm portions 22 and 24 also deform and move in conjunction with this. As the arm portions 22 and 24 deform and move away from the first internal terminal 4, the conductive state between the first internal terminal 4 and the second internal terminal 6 switches to a non-conductive state.

[0040] In this embodiment, the arm portions 22 and 24 move in a direction different from that of the contact portion 20. Specifically, while the contact portion 20 moves in the -Z direction, the arm portions 22 and 24 each move in a Y direction intersecting and perpendicular to the -Z direction. The arm portion 22 moves in the +Y direction (arrow A2 in FIG. 7), and the arm portion 24 moves in the -Y direction (arrow A3). With this structure, compared to a structure in which the arm portions move in the same direction as the contact portion 20, it is possible to reduce the height (dimension in the Z-axis direction) of the switch-equipped coaxial connector 2, thereby achieving a low-profile switch-equipped coaxial connector 2.

[0041] The mounting portion 26 is a portion that is mounted on a substrate (not shown). In the second internal terminal 6, the arm portions 22, 24 have free ends that are not fixed to other members, whereas the mounting portion 26 has a fixed end that is mounted on and fixed to the substrate.

[0042] The extension portion 28 is a portion that extends from the mounting portion 26 toward the contact portion 20 .

[0043] As shown in FIG. 7, the holding member 8A has a protrusion 30, a recess 32, a support surface 34, two recesses 36, 38, and two protrusions 40, 42.

[0044] The protruding portion 30 is a portion that protrudes in the +Z direction, and supports the above-mentioned first inner terminal 4 from below.

[0045] The recessed portion 32 is a portion recessed in the −Z direction, and positions the second internal terminal 6 by arranging the extension portion 28 of the second internal terminal 6 described above.

[0046] The support surface 34 is a surface that supports the arm portions 22, 24 of the second internal terminal 6 from below. The support surface 34 extends in the XY plane and restricts movement of the arm portions 22, 24 in the -Z direction. By providing the support surface 34 extending in the XY plane, the arm portions 22, 24 can move laterally within the XY plane (arrows A2, A3) while in contact with the support surface 34.

[0047] The recesses 36, 38 are recesses provided in the support surface 34 and recessed in the -Z direction. The recesses 36, 38 are formed, for example, as pressing points for ejector pins when the holding member 8A is resin-molded. The recesses 36, 38 in this embodiment are provided at positions overlapping with the movement paths of the arm portions 22, 24, reducing frictional resistance when the arm portions 22, 24 move.

[0048] The protrusions 40, 42 are portions that protrude in the +Z direction outside the support surface 34. The protrusions 40, 42 function as stoppers that suppress excessive movement when the arm portions 22, 24 move in the Y direction and spread outward.

[0049] Next, the detailed configuration of the second internal terminal 6 will be described with reference to FIGS.

[0050] 8 is a plan view of the second inner terminal 6, FIG. 9 is a perspective view of the second inner terminal 6, and FIG. 10 is a side view of the second inner terminal 6. As shown in FIG.

[0051] 8, the second internal terminal 6 further includes a connecting portion 44. The connecting portion 44 is a portion that connects the contact portion 20 and the two arm portions 22, 24, and is also connected to the extending portion .

[0052] Of the two arm portions 22, 24, the arm portion 22 extends from the connecting portion 44 to one side (+Y direction), and the arm portion 24 extends from the connecting portion 44 to the other side (-Y direction).

[0053] The arm portion 22 has a proximal end 46 , a distal end 48 , and an extension portion 50 .

[0054] The base end 46 is a portion extending from the connecting portion 44. The tip end 48 is a portion located at the tip of the arm portion 22, which is a free piece, and has a tip 48A. The tip 48A is the point that contacts the first piece 14 of the first inner terminal 4, and contacts the first piece 14 in the -Y direction (arrow A4). The tip 48A in this embodiment has a linear shape when viewed along the Z direction, and makes point contact with the first piece 14. The extension portion 50 is a portion that extends between the base end 46 and the tip end 48.

[0055] The arm portion 22 of this embodiment has a smoothly curved shape when viewed along the Z direction. The arm portion 22 shown in Fig. 8 extends in an arc shape, extending from the connecting portion 44 with a component in the +Y direction (arrow A5), passing through the extending portion 50, and terminating with a component in the opposite direction, the -Y direction (arrow A6).

[0056] In this embodiment, the width D1 of the base end 46 is greater than the width D2 of the extension 50 and the tip end 48. By narrowing the tip side of the arm 22, the tip end 48 of the arm 22 becomes more likely to elastically deform laterally in conjunction with the deformation of the contact portion 20.

[0057] Similarly, arm 24 has a base end 52, a tip end 54, and an extension 56. Base end 52, tip end 54, and extension 56 have shapes that are bilaterally symmetrical to base end 46, tip end 48, and extension 50 of arm 22 described above.

[0058] The tip portion 54 has a tip 54A that comes into contact with the second piece 16 of the first inner terminal 4, and the tip 54A comes into point contact with the second piece 16 in the +Y direction (arrow A7).

[0059] The arm portion 24 extends from the connection portion 44 with a component in the -Y direction (arrow A8), passes through the extension portion 56, and extends in an arc shape, terminating with a component in the opposite +Y direction (arrow A9).

[0060] As shown in FIG. 9, the arm portions 22 and 24 have a disc spring shape in which the inner portion closer to the contact portion 20 is higher in the Z direction than the outer portion.

[0061] Arm 22 has an inner edge 22A and an outer edge 22B, and is inclined so that it rises from outer edge 22B toward inner edge 22A (arrow A10). Similarly, arm 24 has an inner edge 24A and an outer edge 24B, and is inclined so that it rises from outer edge 24B toward inner edge 24A (arrow A11).

[0062] With this structure, the only places where arm portions 22, 24 come into contact with support surface 34 are the lower ends of outer edge portions 22B, 24B, and inner edge portions 22A, 24A do not come into contact with support surface 34. This reduces frictional resistance when arm portions 22, 24 move, allowing arm portions 22, 24 to move more smoothly.

[0063] Furthermore, by forming the arm portions 22, 24 into a disc spring shape, the contact portion 20 is positioned higher in the +Z direction than the arm portions 22, 24. As a result, when the contact portion 20 is pressed in the -Z direction by the probe 60, the height positions of the contact portion 20 and the arm portions 22, 24 become closer. This makes it easier to shorten the entire second internal terminal 6 in the Z direction, leading to a low profile of the coaxial connector with switch 2.

[0064] The operation of the switch-equipped coaxial connector 2 having the above-described structure will be described with reference to FIGS.

[0065] 11 and 12 are a perspective view and a plan view showing the state in which the coaxial connector with switch 2 is used to carry out an inspection process.

[0066] 11 and 12, when an inspection process is performed using the coaxial connector with a switch 2, the probe 60 of the mating connector is inserted in the -Z direction (arrow A12) through the through hole 13 shown in Fig. 1. This brings the probe 60 into contact with the contact portion 20 of the second inner terminal 6 in the -Z direction.

[0067] Contact portion 20 is deformed in the -Z direction when pressed by probe 60. As contact portion 20 deforms, arm portions 22, 24, which are formed integrally with contact portion 20, also attempt to move in the -Z direction, but support surface 34 of holding member 8A, which extends in the XY plane, restricts movement of arm portions 22, 24 in the -Z direction. Because arm portions 22, 24 are elastically deformable so as to spread outward in the XY plane, arm portion 22 moves in the +Y direction (arrow A13) while maintaining contact with support surface 34, and arm portion 24 moves in the -Y direction (arrow A14).

[0068] As arm portions 22 and 24 move in the +Y and -Y directions, respectively, the contact state of first internal terminal 4 is released and the state switches from a conductive state to a non-conductive state. This switching operation makes it possible to test the electrical characteristics of the RF circuit in a device equipped with switch-equipped coaxial connector 2.

[0069] (summary) As described above, in the second internal terminal 6, the movement direction (-Z direction) of the contact portion 20 pressed by the probe 60 is different from the movement directions (+Y direction, -Y direction) of the arm portions 22, 24, which are in contact with the first internal terminal 4 and move in conjunction with the deformation of the contact portion 20. This makes it possible to shorten the dimension of the coaxial connector with switch 2 in the Z direction and achieve a low profile for the coaxial connector with switch 2, compared to a structure in which the contact portion 20 and the arm portions 22, 24 move in the same -Z direction.

[0070] (Actions and Effects) A coaxial connector with a switch 2 according to one embodiment of the present disclosure is a coaxial connector with a switch comprising a second internal terminal 6 and a first internal terminal 4 which are conductive, an electrically insulating holding member 8, and an external terminal 10 which covers the holding member 8 and is conductive, wherein the second internal terminal 6 has a contact portion 20 which is pressed in the -Z direction (first direction) by a probe 60, arm portions 22, 24 which extend in a direction intersecting the -Z direction and abut against the first internal terminal 4, and a connection portion 44 which connects the contact portion 20 and the arm portions 22, 24, and the holding member 8 has a support surface 34 which faces the arm portions 22, 24 in the -Z direction and supports the arm portions 22, 24, and the support surface 34 restricts the movement of the arm portions 22, 24 in the -Z direction due to the movement of the contact portion 20 in the -Z direction, and moves the arm portions 22, 24 in the Y direction (second direction) which intersects the -Z direction.

[0071] According to this configuration, by moving the arm portions 22, 24 in the Y direction, it is possible to achieve a lower profile for the switch-equipped coaxial connector 2 compared to when the arm portions 22, 24 move in the −Z direction, the same as the contact portion 20.

[0072] In the switch-equipped coaxial connector 2 of one embodiment, the arm portions 22, 24 are free pieces. With this configuration, the arm portions 22, 24 can easily deform and move in the Y direction.

[0073] Furthermore, in the coaxial connector 2 with a switch according to one embodiment, the contact portion 20 is located higher than the arm portions 22, 24 in the +Z direction (height direction) opposite to the -Z direction (first direction). With this configuration, when the contact portion 20 is pressed in the -Z direction, the heights of the contact portion 20 and the arm portions 22, 24 become closer, which leads to a reduction in the height of the coaxial connector 2 with a switch.

[0074] Furthermore, in the switched coaxial connector 2 of one embodiment, when viewed from the −Z direction (first direction), the arm portions 22, 24 extend in a smoothly curved manner from the connection portion 44. This configuration makes it easier for the arm portions 22, 24 to move smoothly in the Y direction.

[0075] In one embodiment of the coaxial connector with switch 2, the arms 22, 24 have a disc spring shape in which the inner edges 22A, 24A are higher than the outer edges 22B, 24B. This configuration reduces frictional resistance between the arms 22, 24 and the support surface 34, allowing the arms 22, 24 to move more smoothly. It also makes it easier to position the contact portion 20 higher than the arms 22, 24, which helps reduce the height of the coaxial connector with switch 2.

[0076] Furthermore, in the coaxial connector with a switch 2 of one embodiment, the arm portion 22 comes into contact with the first internal terminal 4 in the -Y direction (third direction) opposite to the +Y direction (second direction). With this configuration, the dimension of the coaxial connector with a switch 2 in the Z direction can be made shorter than when the arm portion 22 and the first internal terminal 4 come into contact in the Z direction, leading to a reduction in the height of the coaxial connector with a switch 2.

[0077] In the coaxial connector with switch 2 of one embodiment, the arm portion 22 has a base end 46 connected to the connection portion 44, a tip end 48 that contacts the first inner terminal 4, and an extension portion 50 that extends between the base end 46 and the tip end 48. With this configuration, the arm portion 22 can be easily manufactured.

[0078] Furthermore, in the coaxial connector 2 with a switch according to one embodiment, the width D1 of the base end 46 is greater than the width D2 of the extension 50. With this configuration, the tip side of the arm 22 is more likely to deform and move.

[0079] Furthermore, in the coaxial connector with a switch 2 of one embodiment, the arm portions 22, 24 have the arm portion 22 (first arm portion) and the arm portion 24 (second arm portion) respectively extending from the connection portion 44, and the first internal terminal 4 has a first piece 14 that contacts the arm portion 22 and a second piece 16 that contacts the arm portion 24. With this configuration, by providing two or more contact points between the first internal terminal 4 and the second internal terminal 6, the switching operation of the coaxial connector with a switch 2 can be performed with greater precision.

[0080] Furthermore, in the switch-equipped coaxial connector 2 of one embodiment, the support surface 34 has recesses 36, 38 recessed in the −Z direction (first direction), and the arm portions 22, 24 move in the Y direction (second direction) on the recesses 36, 38. With this configuration, the frictional resistance between the arm portions 22, 24 and the support surface 34 can be reduced.

[0081] In the coaxial connector 2 with a switch according to one embodiment, the −Z direction (first direction) in which the second inner terminal 6 is pressed by the probe 60 and the Y direction (second direction) in which the arm portions 22, 24 move are perpendicular to each other. With this configuration, the arm portions 22, 24 are more likely to deform and move as the contact portion 20 deforms and moves.

[0082] A coaxial connector set 100 according to one embodiment of the present disclosure includes a coaxial connector with a switch 2 and a mating connector having a probe 60 that presses in the −Z direction (first direction) the contact portion 20 of the second inner terminal 6 of the coaxial connector with a switch 2. This configuration enables the coaxial connector with a switch 2 to have a low profile.

[0083] Although the present disclosure has been described above with reference to the above-mentioned embodiments, the present disclosure is not limited to the above-mentioned embodiments. For example, in the embodiments, the second internal terminal 6 is provided with two arm portions 22, 24 as movable portions that come into contact with the first internal terminal 4. However, the present disclosure is not limited to such a case, and at least one arm portion may be provided.

[0084] In addition, in the embodiment, the case where the tips 48A, 54A of the arm portions 22, 24 of the second internal terminal 6 are in point contact with the two pieces 14, 16 of the first internal terminal 4 has been described, but the contact is not limited to point contact and may be surface contact, or may be contact at multiple points, or may be in any other manner.

[0085] In addition, in the embodiment, the arm portions 22, 24 that move in the Y direction have been described as coming into contact with the first internal terminal 4 in the Y direction, but contact is not limited to the Y direction and may also be made in the Z direction.
