Description

Coaxial connector with switch

[0001] The present invention relates to a coaxial connector with a switch.

[0002] For example, Patent Document 1 discloses a coaxial connector with a switch, which includes first and second internal terminals, a holding member, and an external terminal covering the holding member, and in which the first internal terminal has a first internal mounting portion and the second internal terminal has a second internal mounting portion as mounting portions used for soldering.

[0003] JP 2017-76499 A

[0004] In the coaxial connector with a switch disclosed in Patent Document 1, the first internal mounting portion is located at the center of the external base portion of the external terminal, and the pair of bifurcated second internal mounting portions are located at positions offset from the center. In this configuration, since the first internal mounting portion is located at the center of the external base portion of the external terminal, the separation distance between the first internal mounting portion and the second internal mounting portion cannot be increased, which makes electric field propagation more likely to occur, resulting in a problem of reduced isolation performance.

[0005] SUMMARY OF THE INVENTION An object of the present invention is to provide a coaxial connector with a switch that suppresses degradation of isolation performance.

[0006] In order to solve the above problems, a coaxial connector with a switch according to one aspect of the present invention is a coaxial connector with a switch comprising: first and second internal terminals having conductivity, a holding member having electrical insulation, and an external terminal covering the holding member and having conductivity, wherein the first internal terminal has a first internal mounting portion on the bottom surface side of the holding member, and the second internal terminal has a second internal mounting portion on the bottom surface side of the holding member, the external terminal has an external base portion located on the top surface side of the holding member, and a first external mounting portion and a second external mounting portion located on the bottom surface side of the holding member, the external base portion has a rectangular shape having a first side portion, a second side portion, a third side portion, and a fourth side portion connected in this order in a bottom view, wherein the first internal mounting portion is located on the first side, the second internal mounting portion is located on the third side, the first external mounting portion is located on the second side, and the second external mounting portion is located on the fourth side, The first internal mounting portion and the second internal mounting portion are offset in opposite directions from each other across the center line of the external base portion.

[0007] According to this invention, since the first internal mounting portion and the second internal mounting portion are offset in opposite directions on either side of the center line, the distance between the first internal mounting portion and the second internal mounting portion becomes larger, making it less likely for electric field propagation to occur, thereby suppressing a decrease in isolation performance.

[0009] Hereinafter, an embodiment of a coaxial connector with a switch 2 according to the present invention 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 length, width, and height directions of the coaxial connector with a switch 2 are defined by the X-axis, Y-axis, and Z-axis, respectively.

[0010] [Coaxial Connector with Switch] A coaxial connector with switch 2 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG.

[0011] As shown in Figures 1 to 3, the coaxial connector with switch 2 comprises a first internal terminal 10 and a second internal terminal 40 which are conductive, a holding member 50 which is electrically insulating, and an external terminal 60 which covers the holding member 50 and is conductive.

[0012] For example, the first internal terminal 10 functions as a movable terminal, and the second internal terminal 40 functions as a fixed terminal. The first internal terminal 10 and the second internal terminal 40 are formed by bending a thin conductive metal plate, and may be made of, for example, stainless steel (SUS: Steel Use Stainless Steel). Stainless steel is a conductive and elastically deformable material. The surfaces of the first internal terminal 10 and the second internal terminal 40 may be gold-plated, for example.

[0013] Although not shown, the first internal terminal 10 has a movable base held by the holding member 50, an elastic deformation portion connected to the movable base, a connecting portion connected to the elastic deformation portion, and a movable contact portion connected to the connecting portion. As shown in Fig. 1, the first internal terminal 10 has one first internal mounting portion 29 on the bottom side for mounting on a land electrode of a circuit board (not shown).

[0014] Although not shown, the movable contact portion of the first internal terminal 10 is configured to be elastically displaceable in the height direction (Z-axis direction) to make contact with and separate from the second internal terminal 40. The elastic deformation portion is configured to be elastically deformable in the longitudinal direction.

[0015] Although not shown, the second inner terminal 40 has a fixed base portion held by the holding member 50 and a fixed contact portion connected to the fixed base. The movable contact portion, which protrudes in a mountain shape, comes into contact with or separates from the fixed contact portion, thereby providing a switching function.

[0016] As shown in FIG. 2, the second internal terminal 40 has one second internal mounting portion 49 on the bottom surface side for mounting on a land electrode of a circuit board (not shown).

[0017] As shown in FIG. 3, the first internal mounting portion 29 and the second internal mounting portion 49 have a rectangular shape when viewed from the bottom.

[0018] 3, the first internal mounting portion 29 and the second internal mounting portion 49 are offset in opposite directions from each other across the center line C of the external base portion 61. That is, the first internal mounting portion 29 is offset toward the fourth side portion 61d with respect to the center line C, and the second internal mounting portion 49 is offset toward the second side portion 61b with respect to the center line C. This increases the separation distance between the first internal mounting portion 29 and the second internal mounting portion 49, making it difficult for electric field propagation to occur, thereby suppressing a decrease in isolation performance even in the miniaturized coaxial connector with switch 2.

[0019] 3, the first internal mounting portion 29 and the second internal mounting portion 49 are offset by the same amount but in opposite directions, which reduces uneven soldering at the first internal mounting portion 29 and the second internal mounting portion 49 and stabilizes the mounting strength.

[0020] 3 , the first internal terminal 10 has a first neck portion 28 that continues to the first internal mounting portion 29 on the base side of the first internal mounting portion 29. The second internal terminal 40 has a second neck portion 48 that continues to the second internal mounting portion 49 on the base side of the second internal mounting portion 49. For example, the first neck portion 28 is narrower than the first internal mounting portion 29, and the second neck portion 48 is narrower than the second internal mounting portion 49. This increases the inductance of the first internal terminal 10 and the second internal terminal 40, thereby reducing the effects of high-frequency noise.

[0021] 3, in bottom view, the first neck portion 28 is located on the side of the second external mounting portion 65, and the second neck portion 48 is located on the side of the first external mounting portion 64. This allows electrostatic coupling to be formed between the first neck portion 28 and the second external mounting portion 65, and also between the second neck portion 48 and the first external mounting portion 64, thereby improving isolation performance.

[0022] 3, when viewed from the bottom, the shape of the first neck portion 28 is different from the shape of the second neck portion 48. This allows the first internal mounting portion 29 and the second internal mounting portion 49 to be distinguished from each other based on the difference in shape between the first neck portion 28 and the second neck portion 48, thereby improving the reliability of mounting.

[0023] As shown in FIGS. 1 and 2, the external terminals 60 are configured to cover the surface of the holding member 50 .

[0024] The external terminal 60 is made of a thin metal plate and, when connected to ground potential, shields against external electromagnetic waves and unwanted radiation from the first internal terminal 10 and the second internal 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 first internal terminal 10 and the second internal terminal 40. The external terminal 60 can be made of, for example, a stainless steel material. The stainless steel material is conductive and elastically deformable. The external terminal 60 can be formed, for example, by bending.

[0025] The external terminal 60 has, for example, an external base portion 61, a first external mounting portion 64, a second external mounting portion 65, and a cylindrical portion 66. The external terminal 60 and the holding member 50 are configured to be fixed integrally by sandwiching the holding member 50 between the external base portion 61 and the first external mounting portion 64 and second external mounting portion 65.

[0026] The external base portion 61 curves and extends from the top surface side to the side surface side of the holding member 50. As shown in Fig. 3, the external base portion 61 has a rectangular shape in bottom view, with a first side portion 61a, a second side portion 61b, a third side portion 61c, and a fourth side portion 61d connected in this order. A center line C of the external base portion 61 crosses the centers of the first side portion 61a and the third side portion 61c and extends parallel to the second side portion 61b and the fourth side portion 61d.

[0027] The external base portion 61 has base cutout portions 69 cut out on each of the first side portion 61 a and the third side portion 61 c so that the first internal mounting portion 29 and the second internal mounting portion 49 are exposed in a top view, respectively. This improves the visibility of the first internal mounting portion 29 and the second internal mounting portion 49, thereby improving the inspection accuracy and maintainability of the first internal mounting portion 29 and the second internal mounting portion 49.

[0028] The cylindrical 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 of a mating coaxial connector (not shown).

[0029] 3, the first external mounting portion 64 and the second external mounting portion 65 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 first external mounting portion 64 and the second external mounting portion 65 with the holding member 50 sandwiched between them, the external base portion 61 and the first external mounting portion 64 and the second external mounting portion 65 are configured to sandwich and hold the holding member 50.

[0030] 3 , the first external mounting portion 64 and the second external mounting portion 65 are located on the second side 61 b ​​and the fourth side 61 d, respectively, and extend along the second side 61 b ​​and the fourth side 61 d. The first internal mounting portion 29 is located on the first side 61 a, and the second internal mounting portion 49 is located on the third side 61 c. The longitudinal direction of the first external mounting portion 64 extends along the center line C, and the longitudinal direction of the second external mounting portion 65 also extends along the center line C. This allows the first internal mounting portion 29 and the second internal mounting portion 49 to be disposed close to the center line C.

[0031] 3 , the first external mounting portion 64 has a first mounting cutout 64c that is partially cut out on the side facing the second internal mounting portion 49, and the second external mounting portion 65 has a second mounting cutout 65c that is partially cut out on the side facing the first internal mounting portion 29. The first internal mounting portion 29 overlaps with the first external mounting portion 64 in a side view from the fourth side 61d, and the second internal mounting portion 49 overlaps with the second external mounting portion 65 in a side view from the second side 61b. This strengthens the electrostatic coupling between the first external mounting portion 64 and the second internal mounting portion 49 and between the second external mounting portion 65 and the first internal mounting portion 29, making it easier for radiated noise to propagate to the first external mounting portion 64 and the second external mounting portion 65, thereby improving isolation performance.

[0032] As shown in Fig. 1, in a side view from the first side 61a, the second mounting cutout 65c is located on one side of the first internal mounting portion 29, and the first external mounting portion 64 is located on the other side of the first internal mounting portion 29, although the second external mounting portion 65 may also be located on one side of the first internal mounting portion 29. As shown in Fig. 2, in a side view from the third side 61c, the first mounting cutout 64c is located on one side of the second internal mounting portion 49, and the second external mounting portion 65 is located on the other side of the second internal mounting portion 49, although the first external mounting portion 64 may also be located on one side of the second internal mounting portion 49. In other words, in a side view, the first external mounting portion 64 is located on at least one side of the first internal mounting portion 29, and the second external mounting portion 65 is located on at least one side of the second internal mounting portion 49. This allows radiation noise to easily propagate to the first external mounting portion 64 and the second external mounting portion 65, thereby improving isolation performance.

[0033] 3 , in a side view from the first side portion 61 a, the edge of the first internal mounting portion 29 and the edge of the second external mounting portion 65 overlap in a straight line, and in a side view from the third side portion 61 c, the edge of the second internal mounting portion 49 and the edge of the first external mounting portion 64 overlap in a straight line. This forms electrostatic coupling between the first external mounting portion 64 and the second internal mounting portion 49, and also between the second external mounting portion 65 and the first internal mounting portion 29, thereby improving isolation performance.

[0034] 3 , in a side view from the fourth side 61 d, the first internal mounting portion 29 faces and is spaced apart from the first external mounting portion 64 and the second mounting cutout 65 c, respectively, and in a side view from the second side 61 b, the second internal mounting portion 49 faces and is spaced apart from the second external mounting portion 65 and the first mounting cutout 64 c, respectively. This prevents the first internal mounting portion 29 and the second internal mounting portion 49 from coming into contact with the second external mounting portion 65 and the first external mounting portion 64, respectively, and allows the first internal mounting portion 29, the second internal mounting portion 49, the first external mounting portion 64, and the second external mounting portion 65 to be arranged compactly.

[0035] 3 , the first external mounting portion 64 has, in bottom view, a first recessed corner 64a formed in a portion facing the first internal mounting portion 29 and a first chamfered portion 64b continuous with the first mounting cutout 64c. The second external mounting portion 65 has, in bottom view, a second recessed corner 65a formed in a portion facing the second internal mounting portion 49 and a second chamfered portion 65b continuous with the second mounting cutout 65c. This provides a separation between the first external mounting portion 64 and the second internal mounting portion 49 and between the second external mounting portion 65 and the first internal mounting portion 29, thereby reducing the effect of flux contained in the solder used during mounting, enabling high-density mounting.

[0036] 3 , 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 the bottom. An electrically insulating resin such as a liquid crystal polymer is used as the holding member 50. The holding member 50 has a first holding portion 51 and a second holding portion 55. The first internal terminal 10 and the second internal 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).

[0037] 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 a central conductor of a mating coaxial connector (not shown).

[0038] The second holding portion 55 has a second base portion 56, and a first extending portion 57 and a second extending portion 58 that extend in the height direction (Z-axis direction) from the second base portion 56 toward the bottom surface. The first extending portion 57 is located in the first mounting cutout 64c, and the second extending portion 58 is located in the second mounting cutout 65c. As a result, the depressions caused by the first mounting cutout 64c and the second mounting cutout 65c are filled by the first extending portion 57 and the second extending portion 58, respectively, thereby stabilizing the posture of the switch-equipped coaxial connector 2 and improving mounting reliability.

[0039] 3, the bottom surface of the holding member 50, i.e., the back surface of the second holding portion 55, has a protrusion 71. The protrusion 71 is located at the center of the back surface of the second holding portion 55 and has a rectangular shape that protrudes in the height direction (Z-axis direction) of the holding member 50 relative to the back surface.

[0040] Therefore, according to the above embodiment, the flux contained in the solder used during mounting can be retained between the first external mounting portion 64 and the protrusion 71, and between the second external mounting portion 65 and the protrusion 71, thereby improving the positioning accuracy during mounting.

[0041] [Modification of Coaxial Connector with Switch] A modified coaxial connector with switch 2 will be described with reference to Fig. 4. Fig. 4 is a bottom view of the modified coaxial connector with switch 2.

[0042] 4 , in the coaxial connector 2 with a switch, the first external mounting portion 64 and the second external mounting portion 65 each have an L-shape when viewed from the bottom. The first external mounting portion 64 has a first wide portion 64f extending in the width direction (Y-axis direction) and a first narrow portion 64g continuing from the first wide portion 64f and extending in the length direction (X-axis direction). The second external mounting portion 65 has a second wide portion 65f extending in the width direction (Y-axis direction) and a second narrow portion 65g continuing from the second wide portion 65f and extending in the length direction (X-axis direction).

[0043] The first internal mounting portion 29 of the first internal terminal 10 and the second internal mounting portion 49 of the second internal terminal 40 are disposed in the second mounting cutout 65c of the second external mounting portion 65 and the first mounting cutout 64c of the first external mounting portion 64, respectively. The first internal mounting portion 29 and the second internal mounting portion 49 are disposed at diagonally opposite corner positions of the holding member 50, with a large offset from each other in opposite directions across the center line C of the external base portion 61.

[0044] The first internal mounting portion 29 overlaps with the first wide portion 64f of the first external mounting portion 64 in a side view from the first side portion 61a, and the second internal mounting portion 49 overlaps with the second wide portion 65f of the second external mounting portion 65 in a side view from the third side portion 61c. In the modified example shown in Figure 4, the overlap is greater than in the embodiment shown in Figure 3. The formation of electrostatic coupling between the first external mounting portion 64 and the second internal mounting portion 49, as well as between the second external mounting portion 65 and the first internal mounting portion 29, improves isolation performance.

[0045] Furthermore, the first internal mounting portion 29 overlaps with the first narrow portion 64g of the first external mounting portion 64 in a side view from the fourth side portion 61d, and the second internal mounting portion 49 overlaps with the second narrow portion 65g of the second external mounting portion 65 in a side view from the second side portion 61b. Electrostatic coupling is formed between the first external mounting portion 64 and the first internal mounting portion 29, and also between the second external mounting portion 65 and the second internal mounting portion 49, thereby improving isolation performance.

[0046] Since the first internal mounting portion 29 and the second internal mounting portion 49 are significantly offset in opposite directions on either side of the center line C, the separation distance between the first internal mounting portion 29 and the second internal mounting portion 49 becomes larger, making it less likely for electric field propagation to occur, thereby further suppressing deterioration in isolation performance even in the miniaturized coaxial connector 2 with a switch.

[0047] The first internal mounting portion 29 is spaced a first distance L1 from the first external mounting portion 64 and a second distance L2 from the second external mounting portion 65. The second distance L2 is sized to be larger than the first distance L1. The first distance L1 and the second distance L2 are not the same, but the second distance L2 is larger than the first distance L1. This makes it difficult for electric field propagation to occur, further suppressing degradation of isolation performance.

[0048] The second internal mounting portion 49 is spaced a fourth distance L4 from the first external mounting portion 64 and a third distance L3 from the second external mounting portion 65. The fourth distance L4 is configured to be larger than the third distance L3. The third distance L3 and the fourth distance L4 are not the same, but the fourth distance L4 is configured to be larger than the third distance L3. This makes it less likely for electric field propagation to occur, further suppressing degradation of isolation performance.

[0049] 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.

[0050] Alternatively, the first external mounting portion 64 may extend to the vicinity of the third side portion 61 c without providing the first mounting cutout 64 c and the first extending portion 57, and the second external mounting portion 65 may extend to the vicinity of the first side portion 61 a without providing the second mounting cutout 65 c and the second extending portion 58. In this case, a concave first corner 64 a may be provided in place of the first chamfered portion 64 b, and a concave second corner 65 a may be provided in place of the second chamfered portion 65 b.

[0051] The protrusion 71 may have a circular shape, an elliptical shape, or a polygonal shape such as a triangular shape, a pentagonal shape, or a hexagonal shape when viewed from the bottom.

[0052] The first internal terminal 10 may have two first internal mounting portions 29, 29, and the two first internal mounting portions 29, 29 may be disposed offset in opposite directions with the center line C of the external base portion 61 in between. The second internal terminal 40 may have two second internal mounting portions 49, 49, and the two second internal mounting portions 49, 49 may be disposed offset in opposite directions with the center line C of the external base portion 61 in between.

[0053] The present invention and its embodiments can be summarized as follows.

[0054] A coaxial connector with a switch (2) according to one aspect of the present disclosure is a coaxial connector with a switch (2) comprising: a first internal terminal (10) and a second internal terminal (40) that are conductive; an electrically insulating holding member (50); and an external terminal (60) that covers the holding member (50) and is conductive; wherein the first internal terminal (10) has a first internal mounting portion (29) on the bottom surface side of the holding member (50), and the second internal terminal (40) has a second internal mounting portion (49) on the bottom surface side of the holding member (50); the external terminal (60) has an external base portion (61) located on the top surface side of the holding member (50), and a first external mounting portion (64) and a second external mounting portion (65) located on the bottom surface side of the holding member (50); the external base portion (61) has a rectangular shape in bottom view, with a first side portion (61a), a second side portion (61b), a third side portion (61c), and a fourth side portion (61d) connected in this order; When viewed from the bottom, the first internal mounting portion 29 is located on the first side 61a, the second internal mounting portion 49 is located on the third side 61c, the first external mounting portion 64 is located on the second side 61b, and the second external mounting portion 65 is located on the fourth side 61d, and the first internal mounting portion 29 and the second internal mounting portion 49 are offset in opposite directions from each other across the center line C of the external base portion 61.

[0055] According to the above configuration, the distance between the first internal mounting portion 29 and the second internal mounting portion 49 is increased, making it less likely for electric field propagation to occur, and therefore, even in a miniaturized coaxial connector 2 with a switch, deterioration in isolation performance can be suppressed.

[0056] In one embodiment of the coaxial connector 2 with a switch, the first external mounting portion 64 has a first mounting cutout portion 64c that is partially cut out on the side of the second internal mounting portion 49, the second external mounting portion 65 has a second mounting cutout portion 65c that is partially cut out on the side of the first internal mounting portion 29, the first internal mounting portion 29 overlaps with the first external mounting portion 64 in a side view from the fourth side portion 61d, and the second internal mounting portion 49 overlaps with the second external mounting portion 65 in a side view from the second side portion 61b.

[0057] According to the above embodiment, the electrostatic coupling between the first external mounting portion 64 and the second internal mounting portion 49 and the electrostatic coupling between the second external mounting portion 65 and the first internal mounting portion 29 are strengthened, which makes it easier for radiated noise to propagate to the first external mounting portion 64 and the second external mounting portion 65, thereby improving isolation performance.

[0058] In one embodiment of the coaxial connector with switch 2, the first external mounting portion 64 has, in a bottom view, a first concave corner 64a formed in a portion facing the first internal mounting portion 29 and a first chamfered portion 64b that is chamfered and connected to the first mounting cutout 64c, and the second external mounting portion 65 has, in a bottom view, a second concave corner 65a formed in a portion facing the second internal mounting portion 49 and a second chamfered portion 65b that is chamfered and connected to the second mounting cutout 65c.

[0059] According to the above embodiment, by providing a gap between the first external mounting portion 64 and the second internal mounting portion 49 and between the second external mounting portion 65 and the first internal mounting portion 29, the influence of the flux contained in the solder used during mounting can be reduced, thereby enabling high-density mounting.

[0060] In the coaxial connector 2 with a switch according to one embodiment, the first internal mounting portion 29 and the second internal mounting portion 49 are offset in opposite directions by the same amount of offset.

[0061] According to the above embodiment, uneven soldering in the first internal mounting portion 29 and the second internal mounting portion 49 is suppressed, and therefore mounting strength is stabilized.

[0062] In addition, in one embodiment of the coaxial connector 2 with a switch, when viewed from the side, the first external mounting portion 64 is located on at least one side of the first internal mounting portion 29, and the second external mounting portion 65 is located on at least one side of the second internal mounting portion 49.

[0063] According to the above embodiment, radiation noise is more likely to propagate to the first external mounting portion 64 and the second external mounting portion 65, thereby improving isolation performance.

[0064] In one embodiment of the coaxial connector 2 with a switch, the longitudinal direction of the first external mounting portion 64 extends along the center line C, and the longitudinal direction of the second external mounting portion 65 extends along the center line C.

[0065] According to the above embodiment, the first internal mounting portion 29 and the second internal mounting portion 49 can be disposed near the center line C.

[0066] In one embodiment of the coaxial connector 2 with a switch, the first internal mounting portion 29 is spaced from the first external mounting portion 64 by a first distance L1 and from the second external mounting portion 65 by a second distance L2, the second distance L2 being larger than the first distance L1; the second internal mounting portion 49 is spaced from the first external mounting portion 64 by a fourth distance L4 and from the second external mounting portion 65 by a third distance L3, the fourth distance L4 being larger than the third distance L3.

[0067] According to the above embodiment, electric field propagation is less likely to occur, so that the degradation of isolation performance can be further suppressed.

[0068] In one embodiment of the coaxial connector with switch 2, the first internal terminal 10 has a first neck portion 28 that is connected to the first internal mounting portion 29 on the base side of the first internal mounting portion 29 and is narrower than the first internal mounting portion 29, and the second internal terminal 40 has a second neck portion 48 that is connected to the second internal mounting portion 49 on the base side of the second internal mounting portion 49 and is narrower than the second internal mounting portion 49.

[0069] According to the above embodiment, the inductance of the first inner terminal 10 and the second inner terminal 40 is increased, so that the influence of high frequency noise can be reduced.

[0070] In addition, in one embodiment of the coaxial connector 2 with a switch, when viewed from the bottom, the first neck portion 28 is located on the side of the second external mounting portion 65, and the second neck portion 48 is located on the side of the first external mounting portion 64.

[0071] According to the above embodiment, electrostatic coupling is formed between the first neck portion 28 and the second external mounting portion 65, and electrostatic coupling is formed between the second neck portion 48 and the first external mounting portion 64, thereby improving isolation performance.
