Description

[Technical field]

[0001] The present invention relates to a switch connector. [Background technology]

[0002] As an example of a conventional invention related to a switch connector, a coaxial connector described in Patent Document 1 is known. The coaxial connector described in Patent Document 1 includes an insulating case divided into a lower insulating case and an upper insulating case, a fixed terminal, a movable terminal, and an external terminal. The external terminal includes a flat portion and four legs provided at each of the four corners of the flat portion. The tip portions of the four legs are formed to be approximately flush with the bottom surface of the lower insulating case, and the coaxial connector has a structure that allows surface mounting.

[0003] [Patent Document 1] Patent No. 3473559 Summary of the Invention [Problem to be solved by the invention]

[0004] In the case of a coaxial connector structure such as that described in Patent Document 1, when mounting the coaxial connector on a printed circuit board or the like by reflow soldering is provided on the bottom surface of each of the tips of at least the four legs, including the bottom surfaces of the tips of each of the four legs, and the bottom surface of the lower insulating case.

[0005] For example, when solder and flux are provided only on the bottom surface of each of the four legs, the soldering work needs to be performed carefully so as not to provide solder and flux on the bottom surface of the lower insulating case, which may increase the number of steps required for mounting. Also, when solder and flux are provided only on the bottom surface of each of the four legs, the area on which the solder and flux are provided is small, which may reduce the bonding strength between the coaxial connector and the printed circuit board. For example, when solder and flux are provided on both the bottom surface of each of the four legs and the bottom surface of the lower insulating case, the molten flux provided on the bottom surface of the lower insulating case may run down the side of the lower insulating case and enter between the external terminal and the insulating case, causing the movable terminal to stick.

[0015] The support portions 23a and 23b are provided on the upper surface S1. The support portions 23a and 23b have a flat surface for supporting the movable terminal 30. The support portion 23a is provided at the front end portion of the left side of the upper surface S1. The support portion 23b is provided at the rear end portion 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 flat surface for supporting the fixed 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 cutout portion 26.

[0017] The terminal portion 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 portion 31, a first right front portion 32, a first right rear portion 33, a drawn-out portion 34, a second right front portion 35, and a second right rear portion 36. The main body portion 31 extends in the left-right direction. The first right front portion 32 extends in the right front direction from the right end of the main body portion 31. The first right rear portion 33 extends in the right rear direction from the right end of the main body portion 31. The drawn-out portion 34 extends in the left lower direction from the left end of the main body portion 31. The second right front portion 35 extends in the right front direction from the right end of the drawn-out portion 34. The second right rear portion 36 extends in the right rear direction from the right end of the drawn-out portion 34. In this embodiment, the material of the movable terminal 30 is a copper-based material such as phosphor bronze. Note that the material of the movable terminal 30 is not limited to a copper-based material such as phosphor bronze, and may be any material that is conductive.

[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 portion 41, a front upper portion 42, a rear upper portion 43, and a drawn-out portion 44. The main body portion 41 extends in the left-right direction. The front upper portion 42 extends in the front-upper direction from the front end of the main body portion 41. The rear upper portion 43 extends in the rear-upper direction from the rear end of the main body portion 41. The drawn-out portion 44 extends in the lower-right direction from the right end of the main body portion 41. In this embodiment, the material of the fixed terminal 40 is a copper-based material such as phosphor bronze. Note that the material of the fixed terminal 40 is not limited to a copper-based material such as phosphor bronze, and may be any material that is conductive.

[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 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 tube portion 51 and support portions 52a, 52b, and 53. In this embodiment, the material of the second resin case 14 is resin. The tube portion 51 has a cylindrical shape with a central axis extending in the vertical direction. The central axis of the tube 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 tube 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 tube portion 51 is open in a mortar shape. The material of the second resin case 14 is not limited to resin, and may be any material that has insulating properties. Furthermore, the tube portion 51 does not have to have a cylindrical shape. Furthermore, the lower end of the tube portion 51 does not have to be open in a cone 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] The support portions 52a and 52b have a flat surface for supporting the movable terminal 30. The support portion 52a is provided at a position overlapping the support portion 23a of the first resin case 11 when viewed in the vertical direction. As a result, the support portion 52a, together with the support portion 23a of the first resin case 11, sandwiches the second right front portion 35 of the movable terminal 30 to support the movable terminal 30 on the first resin case 11. The support portion 52b is provided at a position overlapping the support portion 23b of the first resin case 11 when viewed in the vertical direction. As a result, the support portion 52b, together with the support portion 23b of the first resin case 11, sandwiches the second right rear portion 36 of the movable terminal 30 to support the movable terminal 30 on the first resin case 11.

[0022] The support portion 53 has a flat surface for supporting the fixed terminal 40. When viewed in the up-down direction, the support portion 53 is provided at a position overlapping the support portion 24 of the first resin case 11. 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 on the first resin case 11.

[0023] The external connection terminal 15 includes a tube 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 tube portion 61 has a cylindrical shape with a central axis extending in the vertical direction. The central axis of the tube portion 61 is located at the center of the switch connector 10 when viewed in the vertical direction. The central axis of the tube portion 61 coincides with the central axis of the tube portion 51. The upper and lower ends of the tube 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 tube portion 51 of the second resin case 14 is inserted into the second through hole H2. As a result, the tube portion 61 surrounds the periphery of the first through hole H1 when viewed in the vertical direction. The material of the external connection terminal 15 is not limited to SUS (Stainless Used Steel) and may be any material that is conductive. In addition, the tube portion 61 does not have to have a cylindrical shape. Furthermore, the lower end of the cylindrical portion 61 does not have to be open in a cone shape.

[0024] The main body 62 is provided around the lower end of the tube portion 61. The main body 62 has a plate shape. The main body 62 is formed by bending a plate of SUS (Stainless Used Steel). The main body 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 62 also has a planar portion 71 and legs 72a, 72b. In this embodiment, a first opening OP1 is provided across the planar portion 71 and the leg 72a in the center of the main body 62 in the left-right direction. The first opening OP1 penetrates the outer surface OS and the inner surface IS. A second opening OP2 is provided across the planar portion 71 and the leg 72b in the center of the main body 62 in the left-right direction. 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, and 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. An outer surface OS of the planar portion 71 faces upward. An inner surface IS of the planar portion 71 faces downward.

[0026] The legs 72a and 72b are provided on the sides located at the front and rear ends of the planar portion 71, respectively. That is, the legs 72a and 72b are connected to the planar portion 71. The legs 72a and 72b are formed by bending a part of a plate-like body extending from the planar portion 71 in the front-rear direction. As shown in FIG. 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 sandwich and support the first resin case 11 and the second resin case 14. In other words, the leg 72a wraps around the end of the first resin case 11 in the front direction and sandwiches the first resin case 11 in the up-down direction. The leg 72b wraps around the end of the first resin case 11 in the rear direction and sandwiches the first resin case 11 in the up-down 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 periphery of the protrusions 22a and 22b, respectively, when viewed in the front-rear direction. In addition, the protrusions 22a and 22b of the first resin case 11 are 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 leg 72a and the inner surface IS of the leg 72b, respectively. The external connection terminal 15 as described above is connected to the ground potential.

[0028] As shown in FIG. 3, the inner surface IS of the main body 62 is knurled. More specifically, a plurality of first grooves G1 are formed in a net shape on the inner surface IS of the main body 62. A plurality of first grooves G1 are formed in a net shape around the first opening OP1 and the second opening OP2 on the inner surface IS of the main body 62. A plurality of first grooves G1 are not formed around the second through hole H2 on the inner surface IS of the main body 62. A plurality of first grooves G1 may be formed around the second through hole H2 on the inner surface IS of the main body 62. Each of the plurality of first grooves G1 corresponds to the "uneven portion" of the present invention. The "uneven portion" of the present invention is not limited to the plurality of first grooves G1 formed in a net shape as shown in the switch connectors 10a and 10b described later. The "uneven portion" of the present invention is not limited to the case where it has a concave shape like the first groove G1, but may have a convex shape. Furthermore, the "convex and concave portions" of the present invention are not limited to those that can be observed with the naked eye, but also include those that can be observed using an observation device (for example, a microscope or a magnifying glass, etc.).

[0029] 4, in a normal state (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. When the movable terminal 30 is in contact with the fixed terminal 40, the right end portion of the movable terminal 30 does not contact the upper surface S1 of the first resin case 11.

[0030] 5, during inspection of an electronic device including the switch connector 10 (second state), the movable terminal 30 is pressed downward by the pin 100. This causes the movable terminal 30 to elastically deform downward relative to the fixed terminal 40 and move away from the fixed terminal 40. As a result, high-frequency signals are not transmitted between the movable terminal 30 and the fixed terminal 40. Instead, high-frequency signals are transmitted between the pin 100 and the movable terminal 30.

[0031] [effect] According to the switch connector 10, the area where the solder and flux are provided can be increased, and the number of steps required for mounting can be reduced, and the adhesion of the movable terminal 30 can be suppressed. More specifically, the leg 72a is provided with a first opening OP1 penetrating the outer surface OS and the inner surface IS. As a result, unlike the coaxial connector described in Japanese Patent No. 3473559, the tips of the leg 72a of the switch connector 10 are connected. In addition, the leg 72b is provided with a second opening OP2 penetrating the outer surface OS and the inner surface IS. As a result, unlike the coaxial connector described in Japanese Patent No. 3473559, the tips of the leg 72b of the switch connector 10 are connected. Therefore, the area where the solder and flux are provided can be increased compared to the coaxial connector described in Japanese Patent No. 3473559. Furthermore, because the tips of the legs 72a, 72b are connected, soldering can be easily performed, which prevents an increase in the number of steps required for mounting, and enables the switch connector 10 to be mounted with fewer steps.

[0032] The first resin case 11 also includes protrusions 22a and 22b exposed from the first opening OP1 and the second opening OP2, respectively. Around the first opening OP1 and the second opening OP2 of the inner surface IS of the external connection terminal 15, uneven portions are formed. As a result, even if the molten flux provided at the tips of the legs 72a and 72b runs along the side surface of the external connection terminal 15 and enters the external connection terminal 15 from the first opening OP1 and the second opening OP2, respectively, the molten flux can be stopped by the uneven portions. Therefore, according to the switch connector 10, it is possible to suppress the sticking of the movable terminal 30.

[0033] Furthermore, the switch connector 10 can be made robust. More specifically, when the molten flux provided at the tips of the legs 72a and 72b enters the external connection terminal 15 from the first opening OP1 and the second opening OP2, respectively, the protrusion 22a located in the first opening OP1 and the protrusion 22b located in the second opening OP2 come into contact with the molten flux. Thereafter, the molten flux solidifies by cooling. The solidification of the molten flux firmly bonds the protrusion 22a and the protrusion 22b to the external connection terminal 15. Therefore, the switch connector 10 can be made robust.

[0034] Furthermore, the switch connector 10 can prevent foreign matter from entering through the first opening OP1 and the second opening OP2 when the switch connector 10 is in use. More specifically, at least a portion of each of the first opening OP1 and the second opening OP2 is blocked by flux solidified between each of the protrusions 22a and 22b and the inner surface IS of the external connection terminal 15. Therefore, the switch connector 10 can prevent 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 easy to identify the flux that has entered the external connection terminal 15 from the first opening OP1 and the second opening OP2. More specifically, the first opening OP1 is provided across the planar portion 71 and the leg portion 72a. The second opening OP2 is provided across the planar portion 71 and the leg portion 72b. This makes it possible to photograph the state inside the first opening OP1 and the state inside the second opening OP2 from above with a camera or the like. Therefore, the switch connector 10 makes it easy to identify the flux that has entered the external connection terminal 15 from the first opening OP1 and the second opening OP2.

[0036] Moreover, the switch connector 10 can be made more robust. More specifically, the first opening OP1 is provided across the planar portion 71 and the leg portion 72a. The second opening OP2 is provided across the planar portion 71 and the leg portion 72b. This makes the first opening OP1 and the second opening OP2 larger. This increases the amount of flux that can be retained around the first opening OP1 and the second opening OP2. This increases the bonding area between the first resin case 11 and the external connection terminal 15 by the flux. Therefore, the switch connector 10 can be made more robust.

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

[0038] The switch connector 10 can prevent the tube portion 51 of the second resin case 14 from being hindered from being inserted into the second through hole H2 of the external connection terminal 15. More specifically, the tube portion 51 of the second resin case 14 is inserted into the second through hole H2 of the external connection terminal 15. There is no uneven portion formed around the second through hole H2 on the inner surface IS of the external connection terminal 15. Therefore, the uneven portion does not hinder the insertion of the tube portion 51 into the second through hole H2. As a result, the switch connector 10 can prevent the tube portion 51 of the second resin case 14 from being hindered from being inserted 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, a plurality of 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 from the first opening OP1 and the second opening OP2, respectively, the molten flux can be retained by the plurality of first grooves G1. Therefore, the switch connector 10 can further suppress the sticking of the movable terminal 30.

[0040] [First Modification] A switch connector 10a according to a first modified example of the present invention will be described below with reference to the drawings. FIG. 6 is a perspective view of an external connection terminal 15 of the switch connector 10a. For the sake of explanation, FIG. 6 shows the external connection terminal 15 before bending. In addition, in FIG. 6, only a representative first recess R1 among the multiple first recesses R1 is given a reference symbol.
