[0003] [Patent Document 1] Japanese Patent Application Publication No. 1-265761 Summary of the Invention [Problem to be solved by the invention]

[0004] In the movable terminal disclosed in Patent Document 1, the spring movable part has a central portion that bulges upward in an arc shape, giving the spring movable part spring properties. The ends of the spring movable part are supported and fixed by two spring support parts, and the two spring support parts are positioned and fixed by terminal guide parts of the case. The pressing force on the spring movable part is concentrated at the boundary between the fixed spring support parts and the movable spring movable part, which may cause metal fatigue. In particular, as coaxial connectors with switches become smaller, the length of the spring part in the movable terminal becomes shorter, which increases the stress concentrated on the spring part, making the movable terminal more susceptible to metal fatigue.

[0009] Hereinafter, with reference to the drawings, an embodiment of a coaxial connector with a switch 2 according to the present invention and a coaxial connector set 1 including the coaxial connector with a switch 2 will be described. 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 length direction, width direction, and height direction of the coaxial connector with a switch 2 are defined by the X-axis, the Y-axis, and the Z-axis, respectively.

[0010] [Coaxial connector with switch] A coaxial connector with a switch 2 according to an embodiment of the present invention will be described with reference to FIGS.

[0011] As shown in Figures 7 and 8, the coaxial connector with switch 2 includes a movable terminal 10 and a fixed terminal 40 that are conductive, a holding member 50 that is electrically insulating, and an external terminal 60 that covers the holding member 50 and is conductive.

[0012] As shown in Fig. 5, the holding member 50 has a rectangular shape extending in the length direction (X-axis direction) and width direction (Y-axis direction) when viewed from above, with diagonal corners cut out. For example, an electrically insulating resin such as a liquid crystal polymer is used as the holding member 50. As shown in Figs. 7 and 8, the holding member 50 has a first holding portion 51 and a second holding portion 55. The movable terminal 10 and the fixed terminal 40 are sandwiched and held between the first holding portion 51 and the second holding portion 55 in the height direction (Z-axis direction).

[0013] The first holding portion 51 has a first base portion 52 and an inclined guide portion 53 formed on the first base portion 52. The inclined guide portion 53 has a through hole 54 formed therein for inserting the center conductor 5 (shown in FIGS. 10 and 11) of the mating coaxial connector 3 therethrough.

[0014] The second holding portion 55 has a second base portion 56, and a first boss 57 and a second boss 58 standing upright from the second base portion 56 in the height direction (Z-axis direction). The first boss 57 is used to position the movable terminal 10, and the second boss 58 is used to position the fixed terminal 40. The movable terminal 10 and the fixed terminal 40 each further have a first cutout portion 25 and a second cutout portion 43. The first boss 57 engages with the first cutout portion 25, and the second boss 58 engages with the second cutout portion 43. This makes it easy to position the movable terminal 10 and the fixed terminal 40 relative to the holding member 50.

[0015] 7 to 9, the second holding portion 55 of the holding member 50 further has connection cutout portions 59 that are cut out to accommodate the movable connecting portion 28 and the fixed connecting portion 48, which will be described later. This prevents the movable connecting portion 28 and the fixed connecting portion 48 from protruding from the holding member 50, thereby making it possible to miniaturize the coaxial connector with switch 2.

[0016] As shown in Figures 2, 6, 7, 8, 16 and 17, external terminal 60 is configured to cover the surface of holding member 50, and as shown in Figure 1, has a rectangular shape when viewed from above.

[0017] The external terminal 60 is made of a thin metal plate and, when connected to a ground potential, shields against external electromagnetic waves and unwanted radiation from the movable terminal 10 and the fixed terminal 40, thereby making the space surrounded by the external terminal 60 an electromagnetic wave-shielding space. In other words, the external terminal 60 is a member for electromagnetically shielding the movable terminal 10 and the fixed terminal 40. The external terminal 60 can be made of, for example, stainless steel (SUS: Steel Use Stainless) material. Stainless steel material is conductive and elastically deformable. The external terminal 60 can be formed, for example, by bending.

[0018] The external terminal 60 has, for example, an external base portion 61, a pair of external mounting portions 62, 62, and a cylindrical portion 66. The external terminal 60 and the holding member 50 are configured to be fixed together by sandwiching the holding member 50 between the external base portion 61 and the pair of external mounting portions 62, 62.

[0019] The external base portion 61 extends from the upper surface side to the side surface side of the holding member 50 and has an L-shape in side view. The tubular portion 66 has a cylindrical shape that is concentric with the inclined guide portion 53 and extends in the height direction (Z-axis direction), and is configured to be connectable to the outer conductor 7 of the mating coaxial connector 3.

[0020] 8, the pair of external mounting parts 62, 62 are located on the bottom side of the holding member 50 and extend along the bottom surface of the holding member 50 so as to overlap the holding member 50 in a bottom view. By crimping the pair of external mounting parts 62, 62 with the holding member 50 sandwiched between them, the external base part 61 and the pair of external mounting parts 62, 62 are configured to sandwich and hold the holding member 50.

[0021] 6 to 8, the external terminal 60 further has mounting cutout portions 63 cut out to accommodate the movable mounting portion 29 and the fixed mounting portion 49 (described later) in a non-contact manner. This enables the coaxial connector with switch 2 to be made smaller and thinner. The mounting cutout portions 63 are provided, for example, in corner portions of the external terminal 60.

[0022] As described above, the movable terminal 10 and the fixed terminal 40 are sandwiched and held between the first holding portion 51 and the second holding portion 55 in the height direction (Z-axis direction). The movable terminal 10 and the fixed terminal 40 are formed by bending a thin metal plate having electrical conductivity, and may be made of, for example, stainless steel (SUS: Steel Use Stainless) material. Stainless steel material is a material that is both electrically conductive and elastically deformable. The surfaces of the movable terminal 10 and the fixed terminal 40 may be gold-plated, for example.

[0023] 6 and 7, the fixed terminal 40 has a fixed base 42 held by a holding member 50, and a pair of fixed contact portions 45, 45 connected to the fixed base 42. The pair of fixed contact portions 45, 45 are spaced apart in the longitudinal direction of the fixed base 42. The pair of fixed contact portions 45, 45 protrude and extend toward the movable contact portion 17.

[0024] The movable contact portion 17 has a mountain-like shape, and the mountain-like shape has a gently sloping inclined portion 17a on one side and a gently sloping inclined portion 17b on the other side, which makes it easy to form the movable contact portion 17 having spring properties.

[0025] When the mating coaxial connector 3 is not connected to the coaxial connector with a switch 2, the pair of fixed contact portions 45, 45 abut against the one-side inclined portion 17a and the other-side inclined portion 17b of the gently inclined movable contact portion 17. This ensures a reliable electrical connection between the movable contact portion 17 and the fixed contact portions 45, 45.

[0026] 3, the fixed terminal 40 further has a fixed mounting portion 49 for mounting on a land electrode of a circuit board (not shown) on the bottom side of the holding member 50. As shown in FIG. 14, the fixed terminal 40 further has a fixed connecting portion 48 that connects the fixed base portion 42 and the fixed mounting portion 49.

[0027] 14 and 15, the fixed terminal 40 further has a fixed detection end 44 on the opposite side of the fixed mounting portion 49. The fixed detection end 44 is exposed from the external terminal 60 and is used to detect the presence or absence of an electrical connection between the movable terminal 10 and the fixed terminal 40. This increases the flexibility of the electrical connection inspection.

[0028] 3, 4, and 10 to 13, the movable terminal 10 has a movable base 11 held by a holding member 50, an elastic deformation portion 12 connected to the movable base 11, a connecting portion 15 connected to the elastic deformation portion 12, and a movable contact portion 17 connected to the connecting portion 15. The elastic deformation portion 12 and the movable contact portion 17 extend in their respective longitudinal directions. As shown in FIG. 4, the movable terminal 10 has, for example, a U-shape when viewed from above.

[0029] 3 and 4, the movable base portion 11 is provided at a position in the longitudinal direction of the elastic deformation portion 12. This allows the movable terminal 10 to be configured compactly.

[0030] 10 and 12, the movable base 11 has a first neck portion 26 that is narrow in top view, and the connecting portion 15 has a second neck portion 27 that is narrow in top view. The elastically deforming portion 12 is connected to the first neck portion 26 and the second neck portion 27, and extends while bending in the longitudinal direction in top view. This gives the elastically deforming portion 12 springiness in the direction crossing the longitudinal direction, thereby suppressing stress concentration on the movable base 11.

[0031] 13, the elastic deformation portion 12 has a plate shape that protrudes in the same direction as the movable contact portion 17, and is configured to elastically expand and contract in the longitudinal direction. As a result, the elastic deformation portion 12 has spring properties similar to the movable contact portion 17, and stress concentration on the movable base portion 11 can be suppressed.

[0032] 12 and 13, the elastic deformation portion 12 has, in its longitudinal direction, an upward slope portion 13 located on the movable base portion 11 side and a downward slope portion 14 located on the connecting portion 15 side. The gradient of the upward slope portion 13 is configured to be steeper than the gradient of the downward slope portion 14. This allows the elastic deformation portion 12 to have spring properties even if its length in the longitudinal direction is short.

[0033] The elastic deformation part 12 has a first movable end 21 that functions as a movable end on the opposite side of the movable base part 11 in the longitudinal direction of the elastic deformation part 12. This allows the elastic deformation part 12 to smoothly elastically extend in the longitudinal direction while the mounting surface side (i.e., the bottom surface side) of the first movable end 21 abuts against the holding member 50.

[0034] The first movable end 21 is exposed from the external terminal 60 and serves as a movable detection end for detecting the presence or absence of an electrical connection between the movable terminal 10 and the fixed terminal 40. This increases the degree of freedom in inspecting the electrical connection.

[0035] The length of the elastic deformation portion 12 is configured to be shorter than the length of the movable contact portion 17. This makes it possible to ensure space for providing the movable base portion 11, reduces the longitudinal size of the elastic deformation portion 12, and allows the movable terminal 10 to be made smaller.

[0036] The movable contact portion 17 and the elastic deformation portion 12 extend side by side in a direction perpendicular to the longitudinal direction, which reduces the size of the movable terminal 10 in a direction intersecting the movable contact portion 17 and the elastic deformation portion 12, thereby enabling the movable terminal 10 to be made smaller.

[0037] The connecting portion 15 extends in a direction intersecting the movable contact portion 17 and the elastic deformation portion 12. As a result, the elastic deformation portion 12 extends in the longitudinal direction in response to the movement of the movable contact portion 17 extending in the longitudinal direction, thereby suppressing stress concentration on the movable base portion 11.

[0038] 10 and 11, the movable contact portion 17 of the movable terminal 10 is configured to be elastically deformable in the height direction (Z-axis direction) to move in contact with and separate from the fixed contact portion 45, and is also elastically expandable and contractible in the longitudinal direction, so that it operates like a leaf spring. This allows the movable contact portion 17 to move in contact with and separate from the fixed terminal 40.

[0039] The movable contact portion 17 has a plate shape that protrudes toward the fixed contact portion 45 of the fixed terminal 40. This allows the movable contact portion 17 to have spring properties with a simple shape.

[0040] As shown in FIG. 4 , the movable contact portion 17 has a contact protrusion 19. The contact protrusion 19 is the highest protruding apex of the movable contact portion 17 in the height direction (Z-axis direction), and is located, for example, at the center of the movable contact portion 17 in the longitudinal direction. When the mating coaxial connector 3 is connected to the switch-equipped coaxial connector 2, the contact protrusion 19 is pressed by the center conductor 5 of the mating coaxial connector 3, which will be described later. The contact protrusion 19 acts as a pressed portion that is pressed by the lower end of the center conductor 5 of the mating coaxial connector 3 and deforms toward the second base portion 56 of the second holding portion 55. The contact protrusion 19 is located at the center of the holding member 50. This allows the movable contact portion 17 to be reliably pressed regardless of the rotational position of the switch-equipped coaxial connector 2.

[0041] 11, the movable contact portion 17 has a gently curved mountain shape in a side view, which makes it easy to form the movable contact portion 17 with spring properties.

[0042] The movable contact portion 17 has, at both ends in the longitudinal direction, a second movable end 22 and a third movable end 23 that function as movable ends. This allows the movable contact portion 17 to smoothly elastically stretch in the longitudinal direction while the mounting surface side (i.e., bottom side) of the second movable end 22 and the mounting surface side (i.e., bottom side) of the third movable end 23 each abut against the holding member 50.

[0043] When the movable contact portion 17 abuts against the fixed contact portion 45, the mounting surface side (i.e., bottom surface side) of the second movable end 22 and the third movable end 23, which are the movable ends, abuts against the holding member 50. This stabilizes the amount of displacement of the movable contact portion 17, thereby suppressing variations in the contact and separation operation.

[0044] The movable terminal 10 further has a movable mounting portion 29 on the bottom side of the holding member 50 for mounting on a land electrode of a circuit board (not shown). The movable mounting portion 29 of the movable terminal 10 and the fixed mounting portion 49 of the fixed terminal 40 are located diagonally. This positions the movable mounting portion 29 and the fixed mounting portion 49 apart, improving isolation performance. The movable terminal 10 further has a movable connecting portion 28 connecting the movable base 11 and the movable mounting portion 29.

[0045] The end of the movable mounting portion 29 of the movable terminal 10 and the end of the fixed mounting portion 49 of the fixed terminal 40 are positioned outside the holding member 50 in a bottom view so as not to overlap with the holding member 50. This positions the movable mounting portion 29 and the fixed mounting portion 49 further apart, further improving isolation performance.

[0046] [Coaxial connector set] A coaxial connector set 1 according to an embodiment will be described with reference to FIGS.

[0047] As shown in Figures 18 and 19, the coaxial connector set 1 includes a female coaxial connector 2 with a switch and a male counterpart coaxial connector 3 configured to be connectable to the female coaxial connector 2 with a switch in the height direction (Z-axis direction).

[0048] [Mating coaxial connector] As shown in FIGS. 18 and 19, the mating coaxial connector 3 has a central conductor 5, a bushing member 6, and an outer conductor .

[0049] The central conductor 5 is a conductive member extending in the vertical direction within the outer conductor 7, and is electrically connected to the central conductor of a coaxial cable (not shown). The central conductor 5 is configured to be resiliently movable by an elastic member (not shown). The outer conductor 7 is a conductive member having a cylindrical shape, and is electrically connected to the outer conductor of the coaxial cable (not shown). The bushing member 6 is an insulating member that electrically insulates the central conductor 5 from the outer conductor 7.

[0050] [Coaxial connector set in unattached state] The coaxial connector with a switch 2 is provided, for example, between the antenna and transmitting / receiving circuit of a mobile phone. As shown in Figures 16 and 17, when the mating coaxial connector 3 is not attached to the coaxial connector with a switch 2, the movable contact portion 17 of the movable terminal 10 and the fixed contact portion 45 of the fixed terminal 40 come into contact with each other, electrically connecting the movable terminal 10 and the fixed terminal 40. This electrically connects, for example, the antenna and the transmitting / receiving circuit.

[0051] [Coaxial connector set installation status] As shown in Figures 18 and 19, when the mating coaxial connector 3 is attached to the coaxial connector with a switch 2, the center conductor 5, to which a measuring device (not shown) is connected via a coaxial cable (not shown), is inserted from above into the through hole 54 of the holding member 50. The movable contact portion 17 of the movable terminal 10 is then elastically pressed by the center conductor 5. As a result, the movable contact portion 17 of the movable terminal 10 moves away from the fixed contact portion 45 of the fixed terminal 40, and the center conductor 5 and the movable terminal 10 are electrically connected. This electrically connects, for example, a transmitting / receiving circuit and a measuring device. Therefore, the electrical connection path can be easily switched by switching between the attachment and detachment of the mating coaxial connector 3 to the coaxial connector with a switch 2.

[0052] Furthermore, when a pressing force is applied to the movable contact portion 17, the movable contact portion 17 moves away from the fixed contact portion 45, causing the movable contact portion 17 and the elastic deformation portion 12 to elastically extend in the longitudinal direction, thereby preventing metal fatigue from occurring in the movable terminal 10.

[0053] [Modification of the coaxial connector with a switch] Modifications of the coaxial connector with switch 2 will be described with reference to FIGS.

[0054] 20 , the movable terminal 10 of the coaxial connector with switch 2 according to the first modification has a Z-shape in top view. The connecting portion 15 extends obliquely relative to the movable contact portion 17 and the elastic deformation portion 12. One end of the connecting portion 15 is located on the opposite side of the movable base 11, and the other end of the connecting portion 15 is located on the side of the third movable end 23. In the movable terminal 10 according to the first modification, the elastic deformation portion 12 extends in the longitudinal direction in response to the movement of the movable contact portion 17 extending in the longitudinal direction, so that stress concentration on the movable base 11 can be suppressed.

[0055] 21 , the movable terminal 10 of the coaxial connector with switch 2 according to the second modification has an S-shape in top view. The connecting portion 15 extends obliquely relative to the movable contact portion 17 and the elastic deformation portion 12. One end of the connecting portion 15 is located near the movable base 11, and the other end of the connecting portion 15 is located on the side of the second movable end 22. In the movable terminal 10 according to the second modification, the elastic deformation portion 12 extends in the longitudinal direction in response to the movement of the movable contact portion 17 extending in the longitudinal direction, so that stress concentration on the movable base 11 can be suppressed.

[0056] 22 , the movable terminal 10 of the coaxial connector with a switch 2 according to the third modification has an H-shape in top view. The linking portion 15 extends in a direction perpendicular to the movable contact portion 17 and the elastic deformation portion 12. One end of the linking portion 15 is located near the first movable end 21 of the elastic deformation portion 12, and the other end of the linking portion 15 is located near the second movable end 22 of the movable contact portion 17. In the movable terminal 10 according to the third modification, the elastic deformation portion 12 extends in the longitudinal direction in response to the movement of the movable contact portion 17 extending in the longitudinal direction, so that stress concentration on the movable base 11 can be suppressed.

[0057] 23 , the movable terminal 10 of the coaxial connector with a switch 2 according to the fourth modification has an H-shape in top view. The connecting portion 15 extends in a direction perpendicular to the movable contact portion 17 and the elastic deformation portion 12. One end of the connecting portion 15 is located closer to the movable base portion 11 of the elastic deformation portion 12, and the other end of the connecting portion 15 is located closer to the third movable end 23 of the movable contact portion 17. In the movable terminal 10 according to the fourth modification, the elastic deformation portion 12 extends in the longitudinal direction in response to the movement of the movable contact portion 17 extending in the longitudinal direction, thereby suppressing stress concentration on the movable base portion 11.

[0058] As shown in Fig. 24, the movable terminal 10 of the coaxial connector with switch 2 according to the fifth modification has a V-shape in top view. The movable contact portion 17 extends obliquely relative to the elastic deformation portion 12. The connecting portion 15 and the movable contact portion 17 have a shape in which they partially overlap on the opposite side of the movable base 11. The first movable end 21 and the second movable end 22 are positioned overlapping at the portion corresponding to the bottom of the V. In the movable terminal 10 according to the fifth modification, the elastic deformation portion 12 extends in the longitudinal direction in response to the movement of the movable contact portion 17 extending in the longitudinal direction, thereby suppressing stress concentration on the movable base 11.

[0059] As shown in Fig. 25, the movable terminal 10 of the coaxial connector with a switch 2 according to the sixth modification has a U-shape in top view. The connecting portion 15 extends widely in a direction perpendicular to the movable contact portion 17 and the elastic deformation portion 12. One end of the connecting portion 15 is located near the movable base 11, and the other end of the connecting portion 15 is located near the third movable end 23 of the movable contact portion 17. The first movable end 21 and the second movable end 22 are flush with the side surface located opposite the movable base 11. In the movable terminal 10 according to the sixth modification, the elastic deformation portion 12 extends longitudinally in accordance with the movement of the movable contact portion 17 extending longitudinally, thereby suppressing stress concentration on the movable base 11.

[0060] Although specific embodiments of the present invention have been described, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the present invention.

[0061] When the movable terminal 10 has a V-shape as in variant example 5 shown in Figure 24, the movable mounting portion 29 and the fixed mounting portion 49 may be located at the center of the width direction (X-axis direction) of the holding member 50, and the movable base 11 may have an L-shaped bent shape when viewed from above.
