Summary of the Invention

Problems to be Solved by the Invention

[0004] In the holding member disclosed in Patent Document 1, an annular recess is formed around the protruding portion. As the miniaturization and low-profile of the coaxial connector with a switch progress, it becomes difficult to form a holding member having a minute and complex shape. And, a flat bottom surface extends on the outer peripheral portion of the recess, and mounting portions of the movable terminal, the fixed terminal, and the external terminal are provided on the flat bottom surface. The coaxial connector with a switch is mounted on a circuit board through these mounting portions, but since the flux contained in the solder used at the time of mounting stays between the circuit board and the flat bottom surface, the positioning accuracy of the coaxial connector with a switch deteriorates.

[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, which facilitate miniaturization and low-profile and improve the positioning accuracy at the time of mounting.

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 a conductive movable terminal and a fixed terminal, an electrically insulating retaining member, and a conductive external terminal covering the retaining member, The aforementioned external terminal has a pair of external mounting parts on the bottom side, Each of the pair of external mounting parts has a retaining surface that holds the retaining member by extending along the bottom surface so as to overlap the retaining member when viewed from the bottom, The retaining member has, on its bottom side, a covering portion that is covered by the retaining surface, an exposed portion that extends continuously from the covering portion and is exposed, and a protruding portion that protrudes from the exposed portion in the height direction of the retaining member. [Effects of the Invention]

[0007] According to this invention, the structure of the bottom side of the holding member is simplified because the covering portion and the exposed portion extend continuously, making it easier to miniaturize and reduce the profile. In addition, the flux contained in the solder used during mounting can be retained in the exposed portion located between the external mounting portion and the protruding portion, improving the positioning accuracy during mounting.

[0009] Hereinafter, embodiments of the coaxial connector 2 with a switch and the coaxial connector set 1 equipped with the coaxial connector 2 according to this invention will be described with reference to the drawings.

[0010] [Coaxial connector with switch] A coaxial connector 2 with a switch according to an embodiment of the present invention will be described with reference to Figures 1 to 9.

[0011] As shown in Figures 1 and 2, the coaxial connector with a switch 2 comprises a conductive movable terminal 10 and a fixed terminal 40, an electrically insulating retaining member 50, and an electrically conductive external terminal 60 that covers the retaining member 50.

[0012] The movable terminal 10 and the fixed terminal 40 are formed by bending a thin metal member having conductivity, and for example, a stainless (SUS: Steel Use Stainless) material can be used. The stainless material has conductivity and is a material that can be elastically deformed. For example, gold plating or the like may be performed on the surfaces of the movable terminal 10 and the fixed terminal 40.

[0013] As shown in FIGS. 6 and 7, the movable terminal 10 includes a movable base portion 11 held by a holding member 50, an elastic deformation portion 12 connected to the movable base portion 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 movable terminal 10 further has a movable mounting portion 29 for mounting on a land electrode of a circuit board (not shown) on the bottom surface side of the holding member 50. As shown in FIGS. 1, 2, 3, and 5, the movable terminal 10 further has a movable connecting portion 28 connected to the movable mounting portion 29.

[0014] As shown in FIG. 4, the movable contact portion 17 of the movable terminal 10 is configured to be elastically displaced in the height direction (Z-axis direction) to make contact with and separate from the fixed terminal 40. The elastic deformation portion 12 is configured to be elastically deformable in the longitudinal direction. The movable contact portion 17 has a mountain shape and includes a contact convex portion 19, a first inclined portion and a second inclined portion connected to the contact convex portion 19. The contact convex portion 19 protrudes most in the height direction (Z-axis direction) of the holding member 50 (movable contact portion 17). The contact convex portion 19 serves as a pressed portion that is pressed by the lower end portion of the center conductor 5 of the mating coaxial connector 3 and deformed toward the second base portion 56 of the second holding portion 55.

[0015] As shown in FIGS. 6 and 7, the fixed terminal 40 includes a fixed base portion 42 held by a holding member 50 and a pair of fixed contact portions 45, 45 connected to the fixed base portion 42. Each of the pair of fixed contact portions 45, 45 abuts against a first inclined portion and a second inclined portion of the mountain-shaped protruding movable contact portion 17.

[0016] As described later, when the movable contact portion 17 separates from the fixed contact portion 45 due to the mating of the mating coaxial connector 3 (as shown in Figures 10 and 11), the end located outside the movable contact portion 17 abuts against the retaining member 50, and the movable contact portion 17 elastically stretches in the longitudinal direction. Similarly, the end located outside the elastic deformation portion 12 abuts against the retaining member 50, and the elastic deformation portion 12 elastically stretches in the longitudinal direction.

[0017] 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). The fixed terminal 40 further has a fixed connection portion 48 connected to the fixed mounting portion 49. 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.

[0018] 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 holding member 50 so as not to overlap with the holding member 50 when viewed from below. As a result, the movable mounting portion 29 and the fixed mounting portion 49 are positioned apart, improving isolation performance.

[0019] As shown in Figures 5 to 7, the external terminal 60 is configured to cover the surface of the retaining member 50 and has a rectangular shape when viewed from above.

[0020] The external terminal 60 is made of a thin metal plate and is connected to the ground potential. It 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 example, stainless steel can be used as the external terminal 60. Stainless steel is a material that is both conductive and elastically deformable. The external terminal 60 is formed, for example, by bending.

[0021] 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.

[0022] 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.

[0023] As shown in Figure 3, 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.

[0024] As shown in Figures 8 and 9, each of the pair of external mounting sections 62, 62 has a retaining surface 62a and a mounting surface 62b. The retaining surface 62a is the upper surface that holds the retaining member 50 by extending along the bottom surface so as to overlap the retaining member 50 when viewed from below, and the mounting surface 62b is the lower surface for mounting to the ground electrode of a circuit board (not shown).

[0025] As shown in Figure 6, the external terminal 60 further has a mounting notch 63 cut out to accommodate the movable mounting portion 29 and the fixed mounting portion 49 in a non-contact manner.

[0026] As shown in Figure 3, the pair of external mounting parts 62, 62 have an L-shape when viewed from below. This increases the mounting area of ​​the pair of external mounting parts 62, 62, thereby improving the bonding strength.

[0027] As shown in Figure 3, each of the pair of external mounting parts 62, 62, which have an L-shape when viewed from below, has a wide portion 62f that extends broadly when viewed from below, and a narrow portion 62g that extends narrowly when viewed from below and intersects with the wide portion 62f in a cross direction. When viewed from the side, the wide portion 62f of one of the pair of external mounting parts 62, 62 faces the width direction of the movable connection part 28, and the narrow portion 62g of the other of the pair of external mounting parts 62, 62 faces the thickness direction of the movable connection part 28. The narrow portion 62g of one of the pair of external mounting parts 62, 62 faces the thickness direction of the fixed connection part 48, and the wide portion 62f of the other of the pair of external mounting parts 62, 62 faces the width direction of the fixed connection part 48. This allows for shielding of unwanted radiation from the movable connection part 28 and the fixed connection part 48.

[0028] As shown in Figures 5 to 7, the retaining member 50 has diagonal corners cut out, and in a top view, it has a rectangular shape extending in the length direction (X-axis direction) and the width direction (Y-axis direction). For the retaining member 50, an electrically insulating resin such as liquid crystal polymer is used. The retaining member 50 has a first retaining portion 51 and a second retaining portion 55. The movable terminal 10 and the fixed terminal 40 are held between the first retaining portion 51 and the second retaining portion 55 in the height direction (Z-axis direction).

[0029] 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.

[0030] The second holding portion 55 includes 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 for positioning the movable terminal 10, and the second boss 58 is used for positioning the fixed terminal 40.

[0031] As shown in Figure 7, the bottom side of the retaining member 50, i.e., the back surface of the second retaining part 55, has a protruding part 71, a covering part 73, and an exposed part 75. The covering part 73 is the part covered by the retaining surface 62a of the external mounting part 62. The exposed part 75 extends continuously from the covering part 73 and is the part that is exposed and not covered by the external mounting part 62. The protruding part 71 is the part that protrudes from the exposed part 75 in the height direction (Z-axis direction) of the retaining member 50. As a result, the structure of the bottom side of the retaining member 50 is simplified by the continuous extension of the covering part 73 and the exposed part 75, making it easier to miniaturize and reduce the profile. In addition, flux contained in the solder used during mounting can be retained in the exposed part 75 located between the external mounting part 62 and the protruding part 71, improving the positioning accuracy during mounting.

[0032] As shown in Figure 5, the protrusion 71 is located in the center of the back surface of the second holding portion 55. This allows the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 to be arranged in a balanced manner on the bottom side of the holding member 50.

[0033] The protruding portion 71 has a rectangular shape when viewed from below, formed by four intersecting edges. As a result, the pair of external mounting portions 62, 62 are positioned relative to each edge of the rectangular protruding portion 71, thus stabilizing the position of the pair of external mounting portions 62, 62. Rounded edges are formed at each corner where the edges intersect.

[0034] The side surface of the rectangular projection 71 and the inner surfaces of the pair of external mounting parts 62, 62 extend parallel to each other. This allows the pair of external mounting parts 62, 62 to be brought as close as possible to the side surface of the rectangular projection 71, thereby increasing the mounting area of ​​the pair of external mounting parts 62, 62 and improving the bonding strength.

[0035] The protruding portion 71 has a gate mark 77 in its center. The gate mark 77 is a molding mark that occurs when the second holding portion 55 of the holding member 50 is created by injection molding of a resin material.

[0036] As shown in Figure 4, the protrusion 71 is positioned to correspond to the contact projection 19 of the movable terminal 10. Also, as shown in Figure 10, the protrusion 71 is located on the opposite side of the central conductor 5 of the mating coaxial connector 3, with the movable contact portion 17 of the movable terminal 10 in between. As a result, the pressing force when the contact projection 19 is pressed by the central conductor 5 of the mating coaxial connector 3 is received by the protrusion 71, thereby suppressing the bending of the holding member 50.

[0037] As shown in Figures 4, 8, and 9, the covering portion 73 and the exposed portion 75 are configured to extend flat and be flush with the surface. This further simplifies the structure of the bottom side of the holding member 50, making it easier to miniaturize and reduce the profile. In addition, the flux contained in the solder used during mounting can be retained in the exposed portion 75, improving the positioning accuracy during mounting.

[0038] As shown in Figure 3, the movable mounting section 29, the fixed mounting section 49, and the pair of external mounting sections 62, 62 are positioned in the circumferential direction centered on the protruding section 71 when viewed from below, in the order of movable mounting section 29, one of the pair of external mounting sections 62, 62, fixed mounting section 49, and the other of the pair of external mounting sections 62, 62. This improves the balance of the coaxial connector 2 with switch during mounting, thereby improving the positioning accuracy during mounting.

[0039] The movable mounting section 29 and the fixed mounting section 49 are positioned point-symmetrically with respect to the protruding section 71, and the pair of external mounting sections 62, 62 are also positioned point-symmetrically with respect to the protruding section 71. This further improves the balance of the coaxial connector 2 with switch during mounting, thereby further improving the positioning accuracy during mounting.

[0040] As shown in Figures 4 and 8, in the height direction (Z-axis direction) of the holding member 50, the heights of the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 are configured to be higher than the height of the protruding portion 71. As a result, the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 protrude above the protruding portion 71, thereby improving the reliability of the mounting.

[0041] As shown in Figure 3, gaps 79 are provided between the movable mounting section 29 and the pair of external mounting sections 62, 62, and between the fixed mounting section 49 and the pair of external mounting sections 62, 62, so that the protruding section 71 can be seen through the gaps 79. This makes it easy to check the condition of the protruding section 71.

[0042] [Coaxial connector set] The coaxial connector set 1 according to the embodiment will be described with reference to Figures 10 and 11.

[0043] Figure 10 is a cross-sectional view showing the coaxial connector set 1 according to the embodiment in an installed state. Figure 11 is a cross-sectional perspective view of the coaxial connector set 1 in the installed state shown in Figure 10.

[0044] As shown in Figures 10 and 11, 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).

[0045] [Mutual coaxial connector]

[0046] As shown in Figures 10 and 11, the mating coaxial connector 3 has a central conductor 5, a bushing member 6, and an outer conductor 7.

[0047] 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.

[0048] [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 8 and 9, 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.

[0049] [Installation status in the coaxial connector set] As shown in Figures 10 and 11, 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 retaining member 50. The movable contact portion 17 of the movable terminal 10 is then elastically pressed by the central conductor 5. As mentioned above, the protrusion 71 of the retaining member 50 is located on the opposite side of the central conductor 5. As a result, the pressing force from the central conductor 5 is received by the protrusion 71, thereby suppressing the bending of the retaining member 50.

[0050] When the movable contact portion 17 of the movable terminal 10 is elastically pressed by the central conductor 5, 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. As a result, for example, the transmitting / receiving circuit and the measuring instrument are electrically connected. Therefore, the electrical connection path can be easily switched by switching the mating coaxial connector 3 to and from the coaxial connector 2 with switch.

[0051] [Variations of coaxial connectors with switches] A modified coaxial connector 2 with a switch will be described with reference to Figure 12. Figure 12 is a schematic bottom view illustrating the modified coaxial connector 2 with a switch.

[0052] As shown in Figure 12, in the coaxial connector 2 with a switch, the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 are arranged in the center of the sides of the rectangular-shaped retaining member 50 when viewed from below. At the same time, the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 have a rectangular shape that extends along the length direction (X-axis direction) and width direction (Y-axis direction) of the retaining member 50. The movable mounting portion 29 and the fixed mounting portion 49 are configured so as not to protrude beyond the sides of the retaining member 50.

[0053] The protruding portion 71 is located in the center of the rectangular-shaped retaining member 50 and is also rectangular in shape. The pair of external mounting portions 62, 62 are longer than the protruding portion 71 in a side view so as to cover it. The protruding portion 71 protrudes from the covering portion 73 in the height direction (Z-axis direction) of the retaining member 50. The height of the pair of external mounting portions 62, 62 is configured to be greater than the height of the protruding portion 71. The inner surfaces of the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 extend parallel to the side surface of the protruding portion 71.

[0054] For example, the movable mounting portion 29 and the fixed mounting portion 49 may be in symmetrical positions (line symmetry, point symmetry) with respect to the protruding portion 71, and the pair of external mounting portions 62, 62 may also be in symmetrical positions (line symmetry, point symmetry) with respect to the protruding portion 71. The holding surfaces 62a of the pair of external mounting portions 62, 62 are in contact with the flat covering portion 73 of the second holding portion 55.

[0055] The movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 are spaced apart when viewed from below from above. The back surface of the second holding portion 55 has a covering portion 73 covered by the holding surface 62a, an exposed portion 75 that extends continuously from the covering portion 73 and is exposed, and a protruding portion 71 that protrudes from the exposed portion 75 in the height direction (Z-axis direction) of the holding member 50. The covering portion 73 and the exposed portion 75 are configured to extend flat and be flush with the surface.

[0056] A gap 79 is provided between the movable mounting portion 29 and the pair of external mounting portions 62, 62, and between the fixed mounting portion 49 and the pair of external mounting portions 62, 62, so that the protruding portion 71 can be seen through the gap 79.

[0057] 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.

[0058] As described above, the exposed portion 75 extends flatly, for example, in connection with the flat covering portion 73, but it may also have a structure that locally has minute protrusions or recesses that do not hinder the flow of flux contained in the solder used during mounting.

[0059] In the description that the height of the pair of external mounting parts 62, 62 is greater than the height of the protruding part 71, the phrase "height of the protruding part 71" means the height including the gate trace 77, i.e., the height of the protruding part 71 + the height of the gate trace 77.

[0060] 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.

[0061] The protruding portion 71 may have a circular, elliptical, triangular, pentagonal, or hexagonal shape when viewed from below.

[0062] This invention and its embodiments can be summarized as follows:

[0063] A coaxial connector with a switch according to one aspect of this disclosure is: A coaxial connector with a switch 2 comprises a conductive movable terminal 10 and a fixed terminal 40, an electrically insulating retaining member 50, and a conductive external terminal 60 that covers the retaining member 50, The external terminal 60 has a pair of external mounting parts 62, 62 on its bottom side. Each of the pair of external mounting parts 62, 62 has a retaining surface 62a that holds the retaining member 50 by extending along the bottom surface so as to overlap the retaining member 50 when viewed from the bottom, The retaining member 50 is characterized in that, on its bottom side, it has a covering portion 73 that is covered by the retaining surface 62a, an exposed portion 75 that extends continuously from the covering portion 73 and is exposed, and a protruding portion 71 that protrudes in the height direction of the retaining member 50 relative to the exposed portion 75.

[0064] With the above configuration, the structure of the bottom side of the holding member 50 is simplified because the covering portion 73 and the exposed portion 75 extend continuously, making it easier to miniaturize and reduce the profile. In addition, the flux contained in the solder used during mounting can be retained in the exposed portion 75 located between the external mounting portion 62 and the protruding portion 71, thereby improving the positioning accuracy during mounting.

[0065] Furthermore, in the coaxial connector 2 with a switch of one embodiment, The covering portion 73 and the exposed portion 75 extend flat and are flush with the surface.

[0066] According to the above embodiment, the structure of the bottom side of the holding member 50 is further simplified, making it easier to miniaturize and reduce the profile. In addition, the flux contained in the solder used during mounting can be retained in the exposed portion 75, improving the positioning accuracy during mounting.

[0067] Furthermore, in the coaxial connector 2 with a switch of one embodiment, The movable terminal 10 has a movable mounting portion 29 on its bottom side for mounting on a circuit board. The fixed terminal 40 has a fixed mounting portion 49 on its bottom side for mounting onto the circuit board. In the circumferential direction centered on the protruding portion 71, the movable mounting portion 29, one of the pair of external mounting portions 62, 62, the fixed mounting portion 49, and the other of the pair of external mounting portions 62, 62 are located in that order.

[0068] According to the above embodiment, the balance of the coaxial connector 2 with a switch is improved during mounting, thus improving the positioning accuracy during mounting.

[0069] Furthermore, in the coaxial connector 2 with a switch of one embodiment, In the height direction of the holding member 50, the heights of the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 are higher than the height of the protruding portion 71.

[0070] According to the above embodiment, the movable mounting portion 29, the fixed mounting portion 49, and the pair of external mounting portions 62, 62 protrude more than the protruding portion 71, thereby improving the reliability of the mounting.

[0071] Furthermore, in the coaxial connector 2 with a switch of one embodiment, The movable mounting portion 29 and the fixed mounting portion 49 are positioned point-symmetrically with respect to the protruding portion 71, The pair of external mounting parts 62, 62 are positioned point-symmetrically with respect to the protruding part 71.

[0072] According to the above embodiment, the balance of the coaxial connector 2 with a switch is further improved during implementation, thus further improving the positioning accuracy during implementation.

[0073] Furthermore, in the coaxial connector 2 with a switch of one embodiment, The ends of the movable mounting portion 29 and the fixed mounting portion 49 are positioned outside the holding member 50 so as not to overlap with the holding member 50 when viewed from below.

[0074] According to the above embodiment, the movable mounting part 29 and the fixed mounting part 49 are located apart, thus improving isolation performance.
