Summary of the Invention

Problems to be Solved by the Invention

[0004] When mounting a coaxial connector on a printed circuit board or the like by reflow, in the case of the structure of the coaxial connector described in Patent Document 1, solder and flux are provided on the bottom surface of the tip end portion of each of at least four leg portions and the bottom surface of the lower insulating case.

[0005] For example, if solder and flux are applied only to the bottom surface of each of the four legs, careful soldering is required to avoid applying solder and flux to the bottom surface of the lower insulating case, which may increase the number of steps required for assembly. Also, if solder and flux are applied only to the bottom surface of each of the four legs, the area covered by solder and flux is small, which may result in a weaker bond between the coaxial connector and the printed circuit board. For example, if solder and flux are applied to both the bottom surface of each of the four legs and the bottom surface of the lower insulating case, the molten flux applied to the bottom surface of the lower insulating case may travel along the side of the lower insulating case and enter the space between the external terminals and the insulating case, potentially causing the movable terminals to seize up.

[0006] Therefore, the object of the present invention is to provide a switch connector that can be mounted with fewer steps while increasing the area on which solder and flux are applied, and that can suppress the sticking of movable terminals. [Means for solving the problem]

The external connection terminal wraps around either end of the first insulating case in a second direction perpendicular to the first direction, and includes legs that sandwich the first insulating case in the first direction. The aforementioned external connection terminal is, The outer surface of the aforementioned switch connector facing outwards, The inner surface of the switch connector facing inward, It has, The leg portion is provided with an opening that penetrates the outer surface and the inner surface.

[Figure 15] [[ID=​​​​​​​​​​​​​​​​In this specification, directions are defined as follows: As shown in Figures 1 and 2, the direction in which the second resin case 14 and the first resin case 11 are aligned in this order is defined as the downward direction. The opposite direction of the downward direction is defined as the upward direction. The upward direction corresponds to the "first direction" of the present invention.

The opposite direction of the forward direction is defined as the backward direction. The forward and backward directions correspond to the "second direction" of the present invention. However, the downward, upward, right, left, forward, and backward directions in this specification are directions defined for the convenience of explanation and do not necessarily coincide with the downward, upward, right, left, forward, and backward directions when the switch connector 10 is in use. Furthermore, in each drawing, the downward and upward directions may be swapped, the right and left directions may be swapped, and the forward and backward directions may be swapped.

[0012] As shown in Figures 1 and 2, the switch connector 10 comprises a first resin case 11, a terminal section 12, a second resin case 14, and an external connection terminal 15. As shown in Figure 2, the first resin case 11, the terminal section 12, the second resin case 14, and the external connection terminal 15 are arranged in this order along the upward direction.

[0013] The first resin case 11 includes a plate-like portion 21, protrusions 22a, 22b, and support portions 23a, 23b, 24. In this embodiment, the material of the first resin case 11 is resin. The plate-like portion 21 has a plate shape. More specifically, the plate-like portion 21 has an upper surface S1 and a lower surface S2 arranged in this order along the downward direction, as well as a left side, a right side, a rear side S3, and a front side S4 connecting the upper surface S1 and the lower surface S2. In this embodiment, each of the upper surface S1 and the lower surface S2 has a rectangular shape when viewed in the vertical direction, with a front and rear edge extending in the left-right direction, and a left and right edge extending in the front-rear direction. Rectangular notches 25 and 26 are formed in the center of the two sides of the upper surface S1 that extend in the front-rear direction, for the movable terminal 30 and the fixed terminal 40 to be pulled out to the outside, respectively. Note that the material of the first resin case 11 is not limited to resin, but may be any material that has insulating properties. The first resin case 11 corresponds to the "first insulating case" of the present invention. The upper surface S1 corresponds to the "first main surface" of the present invention. The lower surface S2 corresponds to the "second main surface" of the present invention.

[0014] The projection 22a is located in the center of the front side surface S4 in the left-right direction. The projection 22a protrudes forward from the front side surface S4. The projection 22a has a sloped surface S5 extending forward and downward from the front side surface S4. That is, the sloped surface S5 is inclined with respect to the vertical direction when viewed in the left-right direction. The projection 22b is located in the center of the rear side surface S3 in the left-right direction. The projection 22b protrudes rearward from the rear side surface S3. The projection 22b has a sloped surface S6 extending rearward and downward from the rear side surface S3. That is, the sloped surface S6 is inclined with respect to the vertical direction when viewed in the left-right direction.

[0015] Support portions 23a and 23b are provided on the upper surface S1. Support portions 23a and 23b have planes for supporting the movable terminal 30. Support portion 23a is provided at the front end of the left side of the upper surface S1. Support portion 23b is provided at the rear end of the left side of the upper surface S1.

[0016] The support portion 24 is provided on the upper surface S1. The support portion 24 has a plane for supporting the fixing terminal 40. The support portion 24 is provided in the center of the right side of the upper surface S1. The support portion 24 is located to the right of the notch portion 26.

[0017] The terminal section 12 includes a movable terminal 30 and a fixed terminal 40. The movable terminal 30 is supported by the first resin case 11 and extends in the left-right direction above the upper surface S1 of the first resin case 11. More specifically, the movable terminal 30 includes a main body 31, a first right front section 32, a first right rear section 33, a pull-out section 34, a second right front section 35, and a second right rear section 36. The main body 31 extends in the left-right direction. The first right front section 32 extends in the right front direction from the right end of the main body 31. The first right rear section 33 extends in the right rear direction from the right end of the main body 31. The pull-out section 34 extends in the left-down direction from the left end of the main body 31. The second right front section 35 extends in the right front direction from the right end of the pull-out section 34. The second right rear section 36 extends in the right rear direction from the right end of the pull-out section 34. In this embodiment, the material of the movable terminal 30 is a copper-based material such as phosphor bronze. However, the material of the movable terminal 30 is not limited to a copper-based material such as phosphor bronze; any material that is electrically conductive is acceptable.

[0018] The fixed terminal 40 is supported by the first resin case 11 and is located to the right of the movable terminal 30. More specifically, the fixed terminal 40 includes a main body 41, a front upper part 42, a rear upper part 43, and a pull-out part 44. The main body 41 extends in the left-right direction. The front upper part 42 extends from the front end of the main body 41 in the front-up direction. The rear upper part 43 extends from the rear end of the main body 41 in the rear-up direction. The pull-out part 44 extends from the right end of the main body 41 in the right-down direction. In this embodiment, the material of the fixed terminal 40 is a copper-based material such as phosphor bronze. However, the material of the fixed terminal 40 is not limited to a copper-based material such as phosphor bronze; any material that is conductive is acceptable.

[0019] The right end of the movable terminal 30 is located below the fixed terminal 40 and is in contact with the fixed terminal 40. More specifically, the first right front portion 32 and the first right rear portion 33 of the movable terminal 30 are located below the front upper portion 42 and the rear upper portion 43 of the fixed terminal 40, respectively. In addition, the first right front portion 32 and the first right rear portion 33 of the movable terminal 30 are in contact with the front upper portion 42 and the rear upper portion 43 of the fixed terminal 40, respectively.

[0020] The second resin case 14 is located above the movable terminal 30 and the fixed terminal 40. The second resin case 14 has a cylindrical shape. The second resin case 14 also has an upper surface and a lower surface S7 around the lower end of the cylindrical shape. The lower surface S7 faces downward. The second resin case 14 includes a cylindrical portion 51 and support portions 52a, 52b, and 53. In this embodiment, the material of the second resin case 14 is resin. The cylindrical portion 51 has a cylindrical shape with a central axis extending in the vertical direction. The central axis of the cylindrical portion 51 is located in the center of the switch connector 10 when viewed in the vertical direction. The upper and lower ends of the cylindrical portion 51 are open. In other words, the second resin case 14 is provided with a first through hole H1 that penetrates the second resin case 14 in the vertical direction. In this embodiment, the lower end of the cylindrical portion 51 is open in a mortar shape. Note that the material of the second resin case 14 is not limited to resin; any material with insulating properties is acceptable. Furthermore, the cylindrical portion 51 does not have to be cylindrical in shape. Also, the lower end of the cylindrical portion 51 does not have to be open in a mortar shape. The second resin case 14 corresponds to the "second insulating case" of the present invention. The lower surface S7 corresponds to the "third main surface" of the present invention.

[0021] Support portions 52a and 52b have planes for supporting the movable terminal 30. Support portion 52a is positioned to overlap with support portion 23a of the first resin case 11 when viewed in the vertical direction. As a result, support portion 52a, together with support portion 23a of the first resin case 11, sandwiches the second right front portion 35 of the movable terminal 30 and supports the movable terminal 30 to the first resin case 11. Support portion 52b is positioned to overlap with support portion 23b of the first resin case 11 when viewed in the vertical direction. As a result, support portion 52b, together with support portion 23b of the first resin case 11, sandwiches the second right rear portion 36 of the movable terminal 30 and supports the movable terminal 30 to the first resin case 11.

[0022] The support portion 53 has a flat surface for supporting the fixed terminal 40. The support portion 53 is positioned so as to overlap with the support portion 24 of the first resin case 11 when viewed in the vertical direction. As a result, the support portion 53, together with the support portion 24 of the first resin case 11, sandwiches the main body portion 41 of the fixed terminal 40 and supports the fixed terminal 40 in the first resin case 11.

[0023] The external connection terminal 15 includes a cylindrical portion 61 and a main body portion 62. In this embodiment, the material of the external connection terminal 15 is SUS (Stainless Used Steel). The cylindrical portion 61 has a cylindrical shape with a central axis extending in the vertical direction. The central axis of the cylindrical portion 61 is located in the center of the switch connector 10 when viewed in the vertical direction. The central axis of the cylindrical portion 61 coincides with the central axis of the cylindrical portion 51. The upper and lower ends of the cylindrical portion 61 are open. In other words, the external connection terminal 15 is provided with a second through-hole H2 that penetrates the external connection terminal 15 in the vertical direction. The cylindrical portion 51 of the second resin case 14 is inserted into the second through-hole H2. As a result, the cylindrical portion 61 surrounds the periphery of the first through-hole H1 when viewed in the vertical direction. Note that the material of the external connection terminal 15 is not limited to SUS (Stainless Used Steel), but can be any material that is conductive. Also, the cylindrical portion 61 does not have to have a cylindrical shape. Furthermore, the lower end of the cylindrical portion 61 does not necessarily have to be open in a mortar shape.

[0024] The main body portion 62 is provided around the lower end of the cylindrical portion 61. The main body portion 62 has a plate shape. The main body portion 62 is formed by bending a SUS (Stainless Used Steel) plate. The main body portion 62 has an outer surface OS facing outward from the switch connector 10, and an inner surface IS facing inward from the switch connector 10. The main body portion 62 also has a planar portion 71 and leg portions 72a and 72b. In this embodiment, a first opening OP1 is provided in the center of the main body portion 62 in the left-right direction, spanning the planar portion 71 and the leg portion 72a. The first opening OP1 penetrates the outer surface OS and the inner surface IS. A second opening OP2 is provided in the center of the main body portion 62 in the left-right direction, spanning the planar portion 71 and the leg portion 72b. The second opening OP2 penetrates the outer surface OS and the inner surface IS. The first opening OP1 may be provided only in the leg portion 72a. The second opening OP2 may be provided only in the leg portion 72b.

[0025] The planar portion 71 covers the first resin case 11, the movable terminal 30, the fixed terminal 40, and the second resin case 14 from above. In the planar portion 71, the outer surface OS faces upward. Also, in the planar portion 71, the inner surface IS faces downward.

[0026] The legs 72a and 72b are provided on the edges located at the front and rear ends of the planar portion 71, respectively. In other words, the legs 72a and 72b are connected to the planar portion 71. The legs 72a and 72b are each formed by bending a part of a plate-like body that extends in the front-rear direction from the planar portion 71. As shown in Figure 1, the tips of the legs 72a and 72b are in contact with the lower surface S2 of the first resin case 11. As a result, the legs 72a and 72b support the first resin case 11 and the second resin case 14 by sandwiching them. In other words, the leg 72a wraps around the front end of the first resin case 11 and sandwiches the first resin case 11 in the vertical direction. Similarly, the leg 72b wraps around the rear end of the first resin case 11 and sandwiches the first resin case 11 in the vertical direction.

[0027] When the legs 72a and 72b sandwich the first resin case 11 and the second resin case 14, the protrusions 22a and 22b of the first resin case 11 are inserted into the first opening OP1 and the second opening OP2, respectively. As a result, the first opening OP1 and the second opening OP2 surround the protrusions 22a and 22b, respectively, when viewed in the front-to-back direction. The protrusions 22a and 22b of the first resin case 11 are also exposed from the first opening OP1 and the second opening OP2, respectively. The protrusions 22a and 22b of the first resin case 11 are in contact with the inner surface IS of the legs 72a and 72b, respectively. The external connection terminal 15 as described above is connected to the ground potential.

[0028] As shown in Figure 3, the inner surface IS of the main body 62 is knurled. More specifically, a plurality of first grooves G1 are formed in a mesh pattern on the inner surface IS of the main body 62. A plurality of first grooves G1 are formed in a mesh pattern around the first opening OP1 and the second opening OP2 of the inner surface IS of the main body 62. No plurality of first grooves G1 are formed around the second through hole H2 of the inner surface IS of the main body 62. However, a plurality of first grooves G1 may be formed around the second through hole H2 of the inner surface IS of the main body 62. Each of the plurality of first grooves G1 corresponds to the "recessed portion" of the present invention. The "recessed portion" of the present invention is not limited to a plurality of first grooves G1 formed in a mesh pattern, as shown in the switch connectors 10a and 10b described later. Furthermore, the "recessed portion" of the present invention is not limited to having a recessed shape like the first grooves G1, but may also have a convex shape. Furthermore, the "uneven surface" of the present invention is not limited to those that can be observed with the naked eye, but also includes those that can be observed using an observation device (for example, a microscope or magnifying glass).

[0029] As shown in Figure 4, under normal conditions (first state), the movable terminal 30 is in contact with the fixed terminal 40. This allows high-frequency signals to be transmitted between the movable terminal 30 and the fixed terminal 40. The right end of the movable terminal 30 does not come into contact with the upper surface S1 of the first resin case 11 when the movable terminal 30 is in contact with the fixed terminal 40.

[0030] As shown in Figure 5, during inspection of the electronic device equipped with the switch connector 10 (second state), the movable terminal 30 is pushed downward by the pin 100. As a result, the movable terminal 30 elastically deforms downward relative to the fixed terminal 40 and separates from the fixed terminal 40. Consequently, high-frequency signals are not transmitted between the movable terminal 30 and the fixed terminal 40. Then, high-frequency signals are transmitted between the pin 100 and the movable terminal 30.

[0031] [effect] The switch connector 10 allows for a larger area for solder and flux application while requiring fewer steps for assembly, and also suppresses the sticking of the movable terminal 30. More specifically, the leg portion 72a is provided with a first opening OP1 that penetrates the outer surface OS and the inner surface IS. As a result, unlike the coaxial connector described in Japanese Patent Publication No. 3473559, the tip of the leg portion 72a of the switch connector 10 is connected. Furthermore, the leg portion 72b is provided with a second opening OP2 that penetrates the outer surface OS and the inner surface IS. As a result, unlike the coaxial connector described in Japanese Patent Publication No. 3473559, the tip of the leg portion 72b of the switch connector 10 is connected. Therefore, compared to the coaxial connector described in Japanese Patent Publication No. 3473559, the area for solder and flux application can be increased. Furthermore, because the tips of the legs 72a and 72b are connected, soldering can be easily performed, thereby suppressing an increase in the number of steps required for assembly and enabling the switch connector 10 to be assembled with fewer steps.

[0032] Furthermore, the first resin case 11 includes protrusions 22a and 22b that are exposed from the first opening OP1 and the second opening OP2, respectively. An uneven surface is formed around the first opening OP1 and the second opening OP2 on the inner surface IS of the external connection terminal 15. This allows the molten flux provided at the tips of the legs 72a and 72b to travel along the sides of the external connection terminal 15 and enter the terminal through the first opening OP1 and the second opening OP2, respectively, but it can be retained by the uneven surface. Therefore, the switch connector 10 can suppress the sticking of the movable terminal 30.

[0033] Furthermore, the switch connector 10 can be made more robust. More specifically, when the molten flux provided at the tips of the legs 72a and 72b enters the external connection terminal 15 through the first opening OP1 and the second opening OP2, respectively, the projection 22a located in the first opening OP1 and the projection 22b located in the second opening OP2 come into contact with the molten flux. After this, the molten flux solidifies due to cooling. As the molten flux solidifies, the projections 22a and 22b are firmly bonded to the external connection terminal 15. Therefore, the switch connector 10 can be made more robust.

[0034] Furthermore, the switch connector 10 prevents foreign matter from entering through the first opening OP1 and the second opening OP2 when the switch connector 10 is in use. More specifically, the flux solidified between the projections 22a and 22b and the inner surface IS of the external connection terminal 15 blocks at least a portion of each of the first opening OP1 and the second opening OP2. Therefore, the switch connector 10 prevents foreign matter from entering through the first opening OP1 and the second opening OP2 when the switch connector 10 is in use.

[0035] The switch connector 10 makes it easier to identify flux that has entered the external connection terminal 15 through the first opening OP1 and the second opening OP2. More specifically, the first opening OP1 is provided spanning the planar portion 71 and the leg portion 72a. The second opening OP2 is provided spanning the planar portion 71 and the leg portion 72b. This allows the state inside the first opening OP1 and the state inside the second opening OP2 to be photographed from above with a camera or the like. Therefore, the switch connector 10 makes it easier to identify flux that has entered the external connection terminal 15 through the first opening OP1 and the second opening OP2.

[0036] Furthermore, the switch connector 10 can be made more robust. More specifically, the first opening OP1 is provided spanning the planar portion 71 and the leg portion 72a. The second opening OP2 is provided spanning the planar portion 71 and the leg portion 72b. As a result, the first opening OP1 and the second opening OP2 are enlarged. Consequently, the amount of flux that can be retained around the first opening OP1 and the second opening OP2 increases. This allows for a larger bonding area between the first resin case 11 and the external connection terminal 15 using flux. Therefore, the switch connector 10 can be made more robust.

[0037] Furthermore, the switch connector 10 can be made more robust. More specifically, the projection 22a has a slope S5 that is inclined with respect to the vertical direction when viewed in the left-right direction. Therefore, the contact area between the projection 22a and the molten flux can be increased compared to the case where the projection 22a does not have a slope S5. As a result, when the molten flux solidifies, the projection 22a and the external connection terminal 15 are bonded more firmly. Also, the projection 22b has a slope S6 that is inclined with respect to the vertical direction when viewed in the left-right direction. Therefore, the contact area between the projection 22b and the molten flux can be increased compared to the case where the projection 22b does not have a slope S6. As a result, when the molten flux solidifies, the projection 22b and the external connection terminal 15 are bonded more firmly. Therefore, the switch connector 10 can be made more robust.

[0038] The switch connector 10 prevents obstruction of the insertion of the cylindrical portion 51 of the second resin case 14 into the second through-hole H2 of the external connection terminal 15. More specifically, the cylindrical portion 51 of the second resin case 14 is inserted into the second through-hole H2 of the external connection terminal 15. Therefore, no irregularities are formed around the second through-hole H2 on the inner surface IS of the external connection terminal 15. Consequently, the irregularities do not obstruct the insertion of the cylindrical portion 51 into the second through-hole H2. As a result, the switch connector 10 prevents obstruction of the insertion of the cylindrical portion 51 of the second resin case 14 into the second through-hole H2 of the external connection terminal 15.

[0039] The switch connector 10 can further suppress the sticking of the movable terminal 30. More specifically, multiple first grooves G1 are formed in a mesh pattern on the inner surface IS of the external connection terminal 15. As a result, even if the molten flux provided at the tips of the legs 72a and 72b enters the external connection terminal 15 through the first opening OP1 and the second opening OP2, respectively, it can be contained by the multiple first grooves G1. Therefore, the switch connector 10 can further suppress the sticking of the movable terminal 30.

[0040] [First variation] The following describes a switch connector 10a according to the first modified example of the present invention with reference to the drawings. Figure 6 is a perspective view of the external connection terminal 15 of the switch connector 10a. In Figure 6, the external connection terminal 15 is shown before bending for illustrative purposes. Also, in Figure 6, only a representative first recess R1 among the multiple first recesses R1 is given a reference numeral. In the description of the switch connector 10a according to the first modified example, only the parts that differ from the switch connector 10 according to the first embodiment will be described, and the rest will be omitted.

[0041] As shown in Figure 6, the switch connector 10a differs from the switch connector 10 in that a plurality of first recesses R1 are formed on the inner surface IS of the main body portion 62. Each of the plurality of first recesses R1 is recessed so as to curve outward toward the switch connector 10. Each of the plurality of first recesses R1 corresponds to the "recessed portion" of the present invention.

[0042] The switch connector 10a described above also achieves the same effect as the switch connector 10.

[0043] [Second variation] The switch connector 10b according to a second modification of the present invention will be described below with reference to the drawings. Figure 7 is a perspective view of the external connection terminal 15 of the switch connector 10b. In Figure 7, the external connection terminal 15 is shown before bending for illustrative purposes. Also, in Figure 7, only a representative first groove G1 among the multiple first grooves G1 is given a reference numeral. In the case of the switch connector 10b according to the second modification, only the parts that differ from the switch connector 10 according to the first embodiment will be described, and the rest will be omitted.

[0044] As shown in Figure 7, the switch connector 10b differs from the switch connector 10 in that multiple first grooves G1 extend in the left-right direction. In this modified example, the multiple first grooves G1 are not connected to each other. However, some of the multiple first grooves G1 may be connected to each other.

[0045] The switch connector 10b described above also achieves the same effect as the switch connector 10. Furthermore, the switch connector 10b can further suppress the sticking of the movable terminal 30. More specifically, the multiple first grooves G1 extend in the left-right direction. As a result, the molten flux held in place by the multiple first grooves G1 is prevented from moving in directions other than left-right. Therefore, the multiple first grooves G1 can suppress the molten flux from entering the central part of the switch connector 10b when viewed in the vertical direction. Consequently, the switch connector 10b can further suppress the sticking of the movable terminal 30.

[0046] [Third variation] The switch connector 10c according to a third modification of the present invention will be described below with reference to the drawings. Figure 8 is a perspective view of the first resin case 11 of the switch connector 10c. Figure 9 is a plan view of the first resin case 11 of the switch connector 10c viewed from below. In Figures 8 and 9, only representative second grooves G2 among the multiple second grooves G2 are given reference numerals. Regarding the switch connector 10c according to the third modification, only the parts that differ from the switch connector 10 according to the first embodiment will be described, and the rest will be omitted.

[0047] The switch connector 10c differs from the switch connector 10 in that the upper surface S1 and lower surface S2 of the first resin case 11 are knurled.

[0048] More specifically, as shown in Figure 8, multiple second grooves G2 are formed in a mesh pattern on the upper surface S1 of the first resin case 11. In this modified example, multiple second grooves G2 are also formed in a mesh pattern on the upper surfaces of the support parts 23a, 23b, and 24. Note that the multiple second grooves G2 do not necessarily have to be formed on the upper surfaces of the support parts 23a, 23b, and 24. Also, as shown in Figure 9, multiple second grooves G2 are formed in a mesh pattern on the lower surface S2 of the first resin case 11.

[0049] Furthermore, it is sufficient if a plurality of second grooves G2 are formed in a mesh-like pattern on the upper surface S1 or lower surface S2 of the first resin case 11.

[0050] The switch connector 10c described above also achieves the same effect as the switch connector 10. Furthermore, the switch connector 10c can further suppress the sticking of the movable terminal 30. More specifically, a plurality of second grooves G2 are formed in a mesh pattern on the upper surface S1 or lower surface S2 of the first resin case 11. As a result, even if the molten flux provided at the tips of the legs 72a and 72b enters the external connection terminal 15 through the first opening OP1 and the second opening OP2, respectively, and flows onto the upper surface S1 or lower surface S2 of the first resin case 11, it can be contained by the plurality of second grooves G2. Therefore, the switch connector 10c can further suppress the sticking of the movable terminal 30.

The plurality of second recesses R2 formed on the upper surface S1 of the first resin case 11 are recessed so as to curve downwards. The plurality of second recesses R2 formed on the lower surface S2 of the first resin case 11 are recessed so as to curve upwards.

[0054] Furthermore, it is sufficient if a plurality of second recesses R2 are formed on the upper surface S1 or lower surface S2 of the first resin case 11.

[0057] The switch connector 10e differs from the switch connector 10c in that, as shown in Figure 12, the multiple second grooves G2 formed on the upper surface S1 of the first resin case 11 are not connected to each other, and as shown in Figure 13, the multiple second grooves G2 formed on the lower surface S2 of the first resin case 11 are not connected to each other.

[0058] Furthermore, parts of multiple second grooves G2 may be connected to each other.

In this modified example, multiple third grooves G3 are also formed on the lower surface of the support portion 53. Note that the multiple third grooves G3 do not necessarily have to be formed on the lower surface of the support portion 53.

[0063] The switch connector 10f, as described above, achieves the same effect as the switch connector 10. Furthermore, the switch connector 10f can further suppress the sticking of the movable terminal 30. More specifically, multiple third grooves G3 are formed in a mesh pattern on the lower surface S7 of the second resin case 14. As a result, even if the molten flux provided at the tips of the legs 72a and 72b enters the external connection terminal 15 through the first opening OP1 and the second opening OP2, respectively, and flows onto the lower surface S7 of the second resin case 14, it can be contained by the multiple third grooves G3. Therefore, the switch connector 10f can further suppress the sticking of the movable terminal 30.

[0064] [Seventh variation] The following describes a switch connector 10g according to the seventh modification of the present invention with reference to the drawings. Figure 15 is a plan view of the second resin case 14 of the switch connector 10g viewed from below.
