Summary of the Invention

Problems to be Solved by the Invention

[0004] In the movable terminal disclosed in Patent Document I, the spring movable part has a spring property because the central part of the spring movable part has an arc shape that bulges upward. Both 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 the terminal guide part of the case. Since the pressing force on the spring movable part acts concentratedly on the boundary part between the fixed spring support part and the movable spring movable part, there is a risk of causing metal fatigue. In particular, due to the miniaturization of the coaxial connector with a switch, the length of the spring part in the movable terminal becomes shorter, so the stress concentrated on the spring part increases, and metal fatigue of the movable terminal is likely to occur.

[0005] Therefore, an object of this invention is to provide a coaxial connector with a switch and a coaxial connector set including the coaxial connector with a switch that suppresses the occurrence of metal fatigue in the movable terminal.

Means for Solving the Problems

[0006] To solve the above problems, a coaxial connector with a switch according to one aspect of this invention is: A coaxial connector with a switch, comprising conductive movable terminals and fixed terminals, and an electrically insulating retaining member, The movable terminal has a movable base held by the holding member, an elastically deformable portion connected to the movable base, a connecting portion connected to the elastically deformable portion, and a movable contact portion connected to the connecting portion. The aforementioned fixed terminal has a fixed base portion held by the holding member and a fixed contact portion connected to the fixed base portion. The movable contact portion is configured to move toward and away from the fixed contact portion by elastically displacing in the height direction. The elastically deformable portion is configured to be elastically deformable in the longitudinal direction. [Effects of the Invention]

[0007] According to this invention, when a pressing force is applied to the movable contact portion, both the movable contact portion and the elastically deformable portion are elastically stretched in the longitudinal direction, thereby suppressing metal fatigue in the movable terminal.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of a coaxial connector 2 with a switch and a coaxial connector set 1 including the coaxial connector 2 with a switch according to this invention will be described while referring to the drawings. For convenience, the X-axis, Y-axis, and Z-axis orthogonal to each other are shown in each figure. In this specification, the length direction, width direction, and height direction of the coaxial connector 2 with a switch are defined by the X-axis, Y-axis, and Z-axis, respectively.

[0010] 〔Coaxial Connector with a Switch〕 The coaxial connector 2 with a switch according to an embodiment of this invention will be described while referring to FIGS. 1 to 17.

[0011] As shown in FIGS. 7 and 8, the coaxial connector 2 with a switch includes a conductive movable terminal 10 and fixed terminal 40, a holding member 50 having electrical insulation properties, and an external terminal 60 that covers the holding member 50 and has conductivity.

[0012] As shown in FIG. 5, the holding member 50 has a rectangular shape with diagonal corner portions cut away and extending in the length direction (X-axis direction) and width direction (Y-axis direction) in a top view. As the holding member 50, for example, an electrically insulating resin such as liquid crystal polymer is used. 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 for inserting the central conductor 5 (shown in Figures 10 and 11) of the mating coaxial connector 3.

[0014] The second retaining portion 55 has a second base portion 56 and a first boss 57 and a second boss 58 erected 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 notch 25 and a second notch 43. The first boss 57 engages with the first notch 25 and the second boss 58 engages with the second notch 43. This makes it easy to position the movable terminal 10 and the fixed terminal 40 relative to the retaining member 50.

[0015] As shown in Figures 7 to 9, the second holding portion 55 of the holding member 50 further has a connecting notch 59 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 enabling miniaturization of the coaxial connector 2 with switch.

[0016] As shown in Figures 2, 6, 7, 8, 16, and 17, the external terminal 60 is configured to cover the surface of the retaining 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, by being connected to ground potential, shields against electromagnetic waves from the outside and unwanted radiation from the movable terminal 10 and fixed terminal 40, thereby creating an electromagnetic shielding space within the external terminal 60. In other words, the external terminal 60 is a component for electromagnetically shielding the movable terminal 10 and fixed terminal 40. For the external terminal 60, for example, stainless steel (SUS: Steel Use Stainless) material can be used. Stainless steel material is conductive and elastically deformable. The external terminal 60 is formed, for example, by bending.

[0018] The external terminal 60 includes, 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 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 to the side surface of the holding member 50 and has an L-shape when viewed from the side. The cylindrical portion 66 is concentric with the inclined guide portion 53 and has a cylindrical shape that 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] As shown in Figure 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 when viewed from below. By crimping the pair of external mounting parts 62, 62 with the holding member 50 in between, the external base part 61 and the pair of external mounting parts 62, 62 are configured to hold the holding member 50 by sandwiching it.

[0021] As shown in Figures 6 to 8, the external terminal 60 further has mounting notches 63 cut out to accommodate the movable mounting section 29 and the fixed mounting section 49, respectively, without contact. This makes it possible to miniaturize and reduce the height of the coaxial connector 2 with switch. The mounting notches 63 are provided, for example, at the corners of the external terminal 60.

[0022] As described above, the movable terminal 10 and the fixed terminal 40 are held between the first holding part 51 and the second holding part 55 in the height direction (Z-axis direction). The movable terminal 10 and the fixed terminal 40 are constructed by bending a thin sheet of conductive metal, and materials such as stainless steel (SUS) can be used. Stainless steel is a material that is both conductive and elastically deformable. The surfaces of the movable terminal 10 and the fixed terminal 40 may be plated with gold, for example.

[0023] As shown in Figures 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 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 an inclined portion 17b on the other side. This makes it easy to form a movable contact portion 17 that has spring properties.

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

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

[0027] As shown in Figures 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 whether or not there is an electrical connection between the movable terminal 10 and the fixed terminal 40. This increases the degree of freedom in electrical connection testing.

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

[0029] As shown in Figures 3 and 4, the movable base 11 is positioned along the longitudinal direction of the elastically deformable portion 12. This allows the movable terminal 10 to be constructed compactly.

[0030] As shown in Figures 10 and 12, the movable base 11 has a first neck portion 26 that is narrow in width when viewed from above, and the connecting portion 15 has a second neck portion 27 that is narrow in width when viewed from above. The elastically deformable portion 12 is connected to the first neck portion 26 and the second neck portion 27 and extends while curving in the longitudinal direction when viewed from above. As a result, the elastically deformable portion 12 also has spring properties in the longitudinal direction, so that stress concentration on the movable base 11 can be suppressed.

[0031] As shown in Figure 13, the elastically deformable 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 elastically deformable portion 12 has spring properties similar to the movable contact portion 17, so that stress concentration on the movable base portion 11 can be suppressed.

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

[0033] The elastic deformation portion 12 has a first movable end 21 that acts as a movable end on the side opposite the movable base portion 11 in the longitudinal direction of the elastic deformation portion 12. This allows the elastic deformation portion 12 to stretch elastically in the longitudinal direction while the mounting surface side (i.e., 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 acts 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 electrical connection testing.

[0035] The length of the elastically deformable portion 12 is configured to be shorter than the length of the movable contact portion 17. This allows space to be secured for the movable base portion 11, reduces the longitudinal size of the elastically deformable portion 12, and enables miniaturization of the movable terminal 10.

[0036] The movable contact portion 17 and the elastically deformable portion 12 extend in a direction perpendicular to the longitudinal direction. This reduces the size in the direction intersecting the movable contact portion 17 and the elastically deformable portion 12, allowing the movable terminal 10 to be miniaturized.

[0037] The connecting portion 15 extends in a direction intersecting the movable contact portion 17 and the elastically deformable portion 12. As a result, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, thereby suppressing stress concentration on the movable base portion 11.

[0038] As shown in Figures 10 and 11, the movable contact portion 17 of the movable terminal 10 is configured to move toward and toward the fixed contact portion 45 by elastically deforming in the height direction (Z-axis direction), and is also elastically expandable and contractible in the longitudinal direction, acting like a leaf spring. As a result, the movable contact portion 17 can move toward and toward 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 Figure 4, the movable contact portion 17 has a contact projection 19. The contact projection 19 is the highest protruding apex in the height direction (Z-axis direction) of the movable contact portion 17, and is located, for example, in the center of the longitudinal direction of the movable contact portion 17. When the mating coaxial connector 3 is connected to the coaxial connector with switch 2, the contact projection 19 is pressed by the central conductor 5 of the mating coaxial connector 3, which will be described later. The contact projection 19 acts as a pressed portion that is pressed by the lower end of the central conductor 5 of the mating coaxial connector 3 and deforms toward the second base portion 56 of the second holding portion 55. The contact projection 19 is located in the center of the holding member 50. This ensures that the movable contact portion 17 is reliably pressed regardless of the rotational position of the coaxial connector with switch 2.

[0041] As shown in Figure 11, the movable contact portion 17 has a gently curved mountain-like shape when viewed from the side. This makes it easy to form a movable contact portion 17 with spring properties.

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

[0043] The mounting surface side (i.e., bottom surface side) of the movable ends, the second movable end 22 and the third movable end 23, contact the holding member 50 when the movable contact portion 17 contacts the fixed contact portion 45. This stabilizes the 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 onto 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 opposite each other. As a result, the movable mounting portion 29 and the fixed mounting portion 49 are located far apart, improving isolation performance. The movable terminal 10 further has a movable connecting portion 28 that connects the movable base 11 and the movable mounting portion 29.

[0045] The ends of the movable mounting portion 29 of the movable terminal 10 and the fixed mounting portion 49 of the fixed terminal 40 are positioned outside the retaining member 50 so as not to overlap with the retaining member 50 when viewed from below. As a result, the movable mounting portion 29 and the fixed mounting portion 49 are positioned further apart, further improving the isolation performance.

[0046] [Coaxial connector set] The coaxial connector set 1 according to the embodiment will be described with reference to Figures 18 and 19.

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

[0048] [Mutual coaxial connector] As shown in Figures 18 and 19, the mating coaxial connector 3 has a central conductor 5, a bushing member 6, and an outer conductor 7.

[0049] The central conductor 5 is a conductor member that extends vertically 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 elastically extendable and retractable by an elastic member (not shown). The outer conductor 7 is a conductor member having a cylindrical shape and is electrically connected to the outer conductor of a coaxial cable (not shown). The bushing member 6 is an insulating member that electrically insulates the central conductor 5 and the outer conductor 7.

[0050] [Coaxial connector set in a non-installed state] The coaxial connector with switch 2 is installed, for example, between the antenna and the 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 switch 2, the movable contact portion 17 of the movable terminal 10 and the fixed contact portion 45 of the fixed terminal 40 of the coaxial connector with switch 2 make contact, electrically connecting the movable terminal 10 and the fixed terminal 40. This electrically connects, for example, the antenna and the transmitting / receiving circuit.

[0051] [Installation status in the coaxial connector set] As shown in Figures 18 and 19, when the mating coaxial connector 3 is attached to the coaxial connector 2 with a switch, the central conductor 5, to which a measuring instrument (not shown) is connected via a coaxial cable (not shown), is inserted from top to bottom 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 central conductor 5. As a result, the movable contact portion 17 of the movable terminal 10 separates from the fixed contact portion 45 of the fixed terminal 40, and the central conductor 5 and the movable terminal 10 are electrically connected. This electrically connects, for example, the transmitting / receiving circuit and the measuring instrument. Therefore, the electrical connection path can be easily switched by switching the mating coaxial connector 3 to and from the coaxial connector 2 with a switch.

[0052] Furthermore, when a pressing force is applied to the movable contact portion 17, the movable contact portion 17 separates from the fixed contact portion 45, causing both the movable contact portion 17 and the elastically deformable portion 12 to stretch elastically in the longitudinal direction, thereby suppressing metal fatigue in the movable terminal 10.

[0053] [Variations of coaxial connectors with switches] A modified example of the coaxial connector 2 with a switch will be described with reference to Figures 20 to 25.

[0054] As shown in Figure 20, the movable terminal 10 of the switch-equipped coaxial connector 2 according to Modification 1 has a Z-shape when viewed from above. The connecting portion 15 extends diagonally to the movable contact portion 17 and the elastically deformable portion 12. One end of the connecting portion 15 is located on the opposite side of the movable base portion 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 Modification 1, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, so that stress concentration on the movable base portion 11 can be suppressed.

[0055] As shown in Figure 21, the movable terminal 10 of the switch-equipped coaxial connector 2 according to Modified Example 2 has an S-shape when viewed from above. The connecting portion 15 extends diagonally with respect to the movable contact portion 17 and the elastically deformable portion 12. One end of the connecting portion 15 is located near the movable base portion 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 Modified Example 2, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, so that stress concentration on the movable base portion 11 can be suppressed.

[0056] As shown in Figure 22, the movable terminal 10 of the switch-equipped coaxial connector 2 according to Modified Example 3 has an H-shape when viewed from above. The connecting portion 15 extends in a direction perpendicular to the movable contact portion 17 and the elastically deformable portion 12. One end of the connecting portion 15 is located near the first movable end 21 of the elastically deformable portion 12, and the other end of the connecting portion 15 is located near the second movable end 22 of the movable contact portion 17. In the movable terminal 10 according to Modified Example 3, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, so that stress concentration on the movable base portion 11 can be suppressed.

[0057] As shown in Figure 23, the movable terminal 10 of the switch-equipped coaxial connector 2 according to Modification 4 has an H-shape when viewed from above. The connecting portion 15 extends in a direction perpendicular to the movable contact portion 17 and the elastically deformable portion 12. One end of the connecting portion 15 is located closer to the movable base portion 11 of the elastically deformable 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 Modification 4, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, so that stress concentration on the movable base portion 11 can be suppressed.

[0058] As shown in Figure 24, the movable terminal 10 of the switch-equipped coaxial connector 2 according to Modification 5 has a V-shape when viewed from above. The movable contact portion 17 extends diagonally with respect to the elastically deformable portion 12. The connecting portion 15 and the movable contact portion 17 have a shape that partially overlaps on the opposite side of the movable base portion 11. In the portion corresponding to the bottom of the V-shape, the first movable end 21 and the second movable end 22 are positioned in an overlapping position. In the movable terminal 10 according to Modification 5, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, so stress concentration on the movable base portion 11 can be suppressed.

[0059] As shown in Figure 25, the movable terminal 10 of the switch-equipped coaxial connector 2 according to Modification 6 has a U-shape when viewed from above. The connecting portion 15 extends broadly in a direction perpendicular to the movable contact portion 17 and the elastically deformable portion 12. One end of the connecting portion 15 is located near the movable base portion 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 on the opposite side of the movable base portion 11. In the movable terminal 10 according to Modification 6, the elastically deformable portion 12 extends in the longitudinal direction in accordance with the movement of the movable contact portion 17 as it extends in the longitudinal direction, so that stress concentration on the movable base portion 11 can be suppressed.

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

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

[0062] The movable contact portion 17 may have a trapezoidal shape. The trapezoidal movable contact portion 17 may have a gently sloping inclined portion 17a on one side and an inclined portion 17b on the other side, and a contact protrusion (pressed portion) 19 that protrudes the highest in the height direction (Z-axis direction) of the movable contact portion 17 and extends flat.

[0063] In the elastically deformable portion 12, the gradient of the upward slope portion 13 located on the side of the movable base portion 11 may be configured to be gentler than the gradient of the downward slope portion 14 located on the side of the connecting portion 15.

[0064] The movable contact portion 17 may have two protruding contact portions on both sides of the longitudinal direction of the contact projection 19 that protrude toward the fixed terminal 40, and the fixed terminal 40 may have one fixed contact portion 45 that protrudes in a U-shape from the fixed base portion 42, and the two protruding contact portions may be configured to be able to move toward and away from the fixed contact portion 45.

[0065] This invention and its embodiments can be summarized as follows:
