Description

Technical Field

[0001] The present utility model relates to a switch connector. Background Art

[0002] As an invention related to an existing switch connector, for example, a coaxial connector described in Patent Document 1 is known. The coaxial connector described in Patent Document 1 includes an insulating housing divided into two parts, a lower insulating housing and an upper insulating housing, a fixed terminal, a movable terminal, and an external terminal. The external terminal includes a flat portion and four legs respectively provided at the four corners of the flat portion. The end portions of the four legs are each formed to be substantially flush with the bottom surface of the lower insulating housing, and the coaxial connector has a surface-mountable structure.

[0003] Patent Document 1: Japanese Patent No. 3473559

[0004] In the case of the structure of the coaxial connector described in Patent Document 1, when the coaxial connector is mounted on a printed circuit board or the like by reflow soldering, solder and flux are provided on the bottom surfaces of at least the end portions of the four legs and the bottom surface of the lower insulating housing.

[0005] For example, when solder and flux are provided only on the bottom surfaces of the end portions of the four legs, since it is necessary to prevent the solder and flux from being provided on the bottom surface of the lower insulating housing, careful soldering work is required, and the installation man-hours may increase. In addition, when solder and flux are provided only on the bottom surfaces of the end portions of the four legs, since the area where the solder and flux are provided is small, the bonding strength between the coaxial connector and the printed circuit board may decrease. For example, when solder and flux are provided on both the bottom surfaces of the end portions of the four legs and the bottom surface of the lower insulating housing, the molten flux provided on the bottom surface of the lower insulating housing may flow along the side surface of the lower insulating housing and enter between the external terminal and the insulating housing, causing the fixing of the movable terminal. Summary of the Utility Model

[0006] Therefore, an object of the present utility model is to provide a switch connector that can increase the area where solder and flux are provided, perform installation with less man-hours, and suppress the fixing of the movable terminal.

[0007] The switch connector according to one aspect of the present utility model includes:

[0008] A first insulating housing;

[0009] A terminal portion including a fixed terminal supported by the first insulating housing and a movable terminal supported by the first insulating housing;

[0010] A second insulating housing; and

[0011] External connection terminals

[0012] The first insulating housing, the terminal portion, the second insulating housing, and the external connection terminals are arranged in sequence along a first direction.

[0013] The movable terminal is in contact with the fixed terminal in a first state.

[0014] The movable terminal is separated from the fixed terminal in a second state.

[0015] A first through-hole penetrating the second insulating housing in the first direction is provided in the second insulating housing.

[0016] A second through-hole penetrating the external connection terminal in the first direction is provided in the external connection terminal.

[0017] The external connection terminal includes a leg portion that is wound into any one of the two ends of the first insulating housing in a second direction orthogonal to the first direction and clamps the first insulating housing in the first direction.

[0018] The external connection terminal has:

[0019] An outer surface facing the outer side of the switch connector; and

[0020] An inner surface facing the inner side of the switch connector.

[0021] An opening penetrating between the outer surface and the inner surface is provided in the leg portion.

[0022] The first insulating housing includes a protruding portion exposed from the opening.

[0023] Convex and concave portions are formed around the opening on the inner surface.

[0024] According to the switch connector of the present invention, the area for arranging solder and flux can be increased, the installation can be carried out with less man-hours, and the fixing of the movable terminal can be suppressed. Description of the Drawings

[0048] As Figure 1 and Figure 2 shown, the switch connector 10 includes a first resin housing 11, a terminal portion 12, a second resin housing 14, and an external connection terminal 15. As Figure 2 shown, the first resin housing 11, the terminal portion 12, the second resin housing 14, and the external connection terminal 15 are arranged in sequence along the upper side.

[0049] The first resin housing 11 includes a plate-shaped portion 21, protruding portions 22a, 22b, and supporting portions 23a, 23b, 24.

[0051] The supporting portions 23a and 23b are provided on the upper surface S1. The supporting portions 23a and 23b have planes for supporting the movable terminal 30. The supporting portion 23a is provided at the front end portion of the left side edge of the upper surface S1.

[0052] The supporting portion 24 is provided on the upper surface S1. The supporting portion 24 has a plane for supporting the fixed terminal 40. The supporting portion 24 is provided at the central portion of the right side edge of the upper surface S1. The supporting portion 24 is located on the right side of the notch portion 26.

[0053] The terminal portion 12 includes a movable terminal 30 and a fixed terminal 40. The movable terminal 30 is supported by the first resin housing 11 and extends in the left - right direction above the upper surface S1 of the first resin housing 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 lead - 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 right - forward from the right end of the main body portion 31. The first right rear portion 33 extends right - backward from the right end of the main body portion 31.

The second right front portion 35 extends right - forward from the right end of the lead - out portion 34. The second right rear portion 36 extends right - backward from the right end of the lead - out portion 34. In the present embodiment, the material of the movable terminal 30 is a copper - based material such as phosphor bronze. In addition, the material of the movable terminal 30 is not limited to copper - based materials such as phosphor bronze, as long as it has conductivity.

[0054] The fixed terminal 40 is supported by the first resin housing 11 and is located on the right side 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 lead - out portion 44. The main body portion 41 extends in the left - right direction. The front upper portion 42 extends forward and upward from the front end of the main body portion 41. The rear upper portion 43 extends backward and upward from the rear end of the main body portion 41. The lead - out portion 44 extends right - downward from the right end of the main body portion 41. In the present embodiment, the material of the fixed terminal 40 is a copper - based material such as phosphor bronze. In addition, the material of the fixed terminal 40 is not limited to copper - based materials such as phosphor bronze, as long as it has conductivity.

[0055] The right end of the movable terminal 30 is located below the fixed terminal 40 and contacts 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 respectively located below the front upper portion 42 and the rear upper portion 43 of the fixed terminal 40. In addition, the first right front portion 32 and the first right rear portion 33 of the movable terminal 30 respectively contact the front upper portion 42 and the rear upper portion 43 of the fixed terminal 40.

[0056] The second resin housing 14 is located above the movable terminal 30 and the fixed terminal 40. The second resin housing 14 has a cylindrical shape. In addition, the second resin housing 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 housing 14 includes a cylindrical portion 51 and support portions 52a, 52b, 53. In the present embodiment, the material of the second resin housing 14 is resin. The cylindrical portion 51 has a cylindrical shape with a central axis extending in the vertical direction. When viewed in the vertical direction, the central axis of the cylindrical portion 51 is located at the central portion of the switch connector 10. The upper end and the lower end of the cylindrical portion 51 are open. In other words, a first through hole H1 penetrating the second resin housing 14 in the vertical direction is provided in the second resin housing 14. In the present embodiment, the lower end of the cylindrical portion 51 opens in a mortar shape. In addition, the material of the second resin housing 14 is not limited to resin as long as it has insulating properties. In addition, the cylindrical portion 51 may not have a cylindrical shape. In addition, the lower end of the cylindrical portion 51 may not open in a mortar shape. The second resin housing 14 corresponds to the "second insulating housing" in the technical solution. The lower surface S7 corresponds to the "third main surface" in the technical solution.

[0057] The support portions 52a, 52b have planes for supporting the movable terminal 30. When viewed in the vertical direction, the support portion 52a is provided at a position overlapping with the support portion 23a of the first resin housing 11. Thus, the support portion 52a and the support portion 23a of the first resin housing 11 together clamp the second right front portion 35 of the movable terminal 30, and support the movable terminal 30 on the first resin housing 11. When viewed in the vertical direction, the support portion 52b is provided at a position overlapping with the support portion 23b of the first resin housing 11. Thus, the support portion 52b and the support portion 23b of the first resin housing 11 together clamp the second right rear portion 36 of the movable terminal 30, and support the movable terminal 30 on the first resin housing 11.

[0058] The support portion 53 has a plane for supporting the fixed terminal 40. When viewed in the vertical direction, the support portion 53 is provided at a position overlapping with the support portion 24 of the first resin housing 11. Thus, the support portion 53 and the support portion 24 of the first resin housing 11 together clamp the main body portion 41 of the fixed terminal 40, and support the fixed terminal 40 on the first resin housing 11.

[0059] The external connection terminal 15 includes a cylindrical portion 61 and a main body portion 62. In the present embodiment, the material of the external connection terminal 15 is SUS (Stainless Used Steel: stainless steel). The cylindrical portion 61 has a cylindrical shape with a central axis extending in the vertical direction. When viewed in the vertical direction, the central axis of the cylindrical portion 61 is located at the central portion of the switch connector 10. The central axis of the cylindrical portion 61 is aligned with the central axis of the cylindrical portion 51. The upper and lower ends of the cylindrical portion 61 are open. In other words, a second through hole H2 penetrating the external connection terminal 15 in the vertical direction is provided in the external connection terminal 15. The cylindrical portion 51 of the second resin housing 14 is inserted into the second through hole H2. Thus, when viewed in the vertical direction, the cylindrical portion 61 surrounds the first through hole H1 from all around. In addition, the material of the external connection terminal 15 is not limited to SUS (Stainless Used Steel), as long as it has conductivity. Additionally, the cylindrical portion 61 may not have a cylindrical shape. Also, the lower end of the cylindrical portion 61 may not open in a mortar shape.

[0060] 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 plate of SUS (Stainless Used Steel). The main body portion 62 has an outer surface OS facing the outer side of the switch connector 10 and an inner surface IS facing the inner side of the switch connector 10. Additionally, the main body portion 62 has a planar portion 71 and leg portions 72a, 72b. In the present embodiment, a first opening OP1 is provided across the planar portion 71 and the leg portion 72a at the central portion of the main body portion 62 in the left - right direction. The first opening OP1 penetrates between the outer surface OS and the inner surface IS. Also, a second opening OP2 is provided across the planar portion 71 and the leg portion 72b at the central portion of the main body portion 62 in the left - right direction. The second opening OP2 penetrates between the outer surface OS and the inner surface IS. Further, the first opening OP1 may be provided only in the leg portion 72a. Also, the second opening OP2 may be provided only in the leg portion 72b.

[0061] The planar portion 71 covers the first resin housing 11, the movable terminal 30, the fixed terminal 40, and the second resin housing 14 from above. In the planar portion 71, the outer surface OS faces upward. Additionally, in the planar portion 71, the inner surface IS faces downward.

[0062] The leg portions 72a, 72b are respectively provided at the edges of the planar portion 71 located at the front end and the rear end. That is, the leg portions 72a, 72b are connected to the planar portion 71. The leg portions 72a, 72b are respectively formed by bending a part of a plate - like body extending in the front - rear direction from the planar portion 71. As Figure 1As shown, the ends of legs 72a and 72b are in contact with the lower surface S2 of the first resin housing 11. Thus, legs 72a and 72b sandwich the first resin housing 11 and the second resin housing 14 and support the first resin housing 11 and the second resin housing 14. In other words, leg 72a is wound around the front end portion of the first resin housing 11 and clamps the first resin housing 11 in the vertical direction. Further, leg 72b is wound around the rear end portion of the first resin housing 11 and clamps the first resin housing 11 in the vertical direction.

[0063] When legs 72a and 72b sandwich the first resin housing 11 and the second resin housing 14, the protrusions 22a and 22b of the first resin housing 11 are respectively inserted into the first opening OP1 and the second opening OP2. Thus, when viewed in the front-rear direction, the first opening OP1 and the second opening OP2 respectively surround the protrusions 22a and 22b from all around. Further, the protrusions 22a and 22b of the first resin housing 11 are respectively exposed from the first opening OP1 and the second opening OP2. The protrusions 22a and 22b of the first resin housing 11 are respectively in contact with the inner surface IS of leg 72a and the inner surface IS of leg 72b. The external connection terminal 15 as described above is connected to the ground potential.

[0064] As Figure 3 shown, knurling is performed on the inner surface IS of the main body portion 62. More specifically, a plurality of first grooves G1 are formed in a mesh pattern on the inner surface IS of the main body portion 62. A plurality of first grooves G1 are formed in a mesh pattern around the first opening OP1 and the second opening OP2 on the inner surface IS of the main body portion 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 portion 62. Further, a plurality of first grooves G1 may be formed around the second through hole H2 on the inner surface IS of the main body portion 62. The plurality of first grooves G1 respectively correspond to the "concavo-convex portion" in the technical solution. Further, as shown by the switch connectors 10a and 10b described later, the "concavo-convex portion" in the technical solution is not limited to the plurality of first grooves G1 formed in a mesh pattern. Further, the "concavo-convex portion" in the technical solution is not limited to having a concave shape such as the first groove G1, and may have a convex shape. Further, the "concavo-convex portion" in the technical solution is not limited to a structure observable by the naked eye, and also includes a structure observable using an observation device (for example, a microscope or a magnifying glass, etc.).

[0065] As Figure 4 shown, in the normal state (first state), the movable terminal 30 is in contact with the fixed terminal 40. Thus, a high-frequency signal is transmitted between the movable terminal 30 and the fixed terminal 40. In the state where the movable terminal 30 is in contact with the fixed terminal 40, the right end portion of the movable terminal 30 is not in contact with the upper surface S1 of the first resin housing 11.

[0066] AsFigure 5 As shown, when inspecting the electronic device equipped with the switch connector 10 (second state), the movable terminal 30 is pressed 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. Thereby, high-frequency signals are not transmitted between the movable terminal 30 and the fixed terminal 40. Moreover, high-frequency signals are transmitted between the pin 100 and the movable terminal 30.

[0067] [Effect]

[0068] According to the switch connector 10, it is possible to increase the area for setting solder and flux, perform installation with less man-hours, and suppress the fixing of the movable terminal 30. More specifically, a first opening OP1 penetrating between the outer surface OS and the inner surface IS is provided in the leg portion 72a. Thus, different from the coaxial connector described in Japanese Patent No. 3473559, the ends of the leg portions 72a of the switch connector 10 are connected. In addition, a second opening OP2 penetrating between the outer surface OS and the inner surface IS is provided in the leg portion 72b. Thus, different from the coaxial connector described in Japanese Patent No. 3473559, the ends of the leg portions 72b of the switch connector 10 are connected. Therefore, compared with the coaxial connector described in Japanese Patent No. 3473559, it is possible to increase the area for setting solder and flux. In addition, since the ends of the leg portions 72a and 72b are connected, soldering work can be easily performed. Therefore, an increase in installation man-hours can be suppressed, and the switch connector 10 can be installed with less man-hours.

[0069] In addition, the first resin housing 11 includes protrusion portions 22a and 22b respectively exposed from the first opening OP1 and the second opening OP2. Concavo-convex portions are formed around the first opening OP1 and the second opening OP2 on the inner surface IS of the external connection terminal 15. Thus, even if the molten flux provided at the ends of the leg portions 72a and 72b enters the external connection terminal 15 from the first opening OP1 and the second opening OP2 along the side surface of the external connection terminal 15 respectively, the molten flux can be retained by the concavo-convex portions. Therefore, according to the switch connector 10, the fixing of the movable terminal 30 can be suppressed.

[0070] In addition, according to the switch connector 10, the switch connector 10 can be made firm. More specifically, when the soldering fluxes provided at the ends of the legs 72a and 72b enter 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 soldering flux. Then, upon cooling, the soldering flux solidifies. By the solidification of the soldering flux, the protrusion 22a and the protrusion 22b are each firmly bonded to the external connection terminal 15. Therefore, according to the switch connector 10, the switch connector 10 can be made firm.

[0071] In addition, according to the switch connector 10, when the switch connector 10 is in use, it is possible to suppress the entry of foreign matter from the first opening OP1 and the second opening OP2. More specifically, at least a part of each of the first opening OP1 and the second opening OP2 is blocked by the solder solidified between the protrusion 22a and the protrusion 22b and the inner surface IS of the external connection terminal 15. Therefore, according to the switch connector 10, when the switch connector 10 is in use, it is possible to suppress the entry of foreign matter from the first opening OP1 and the second opening OP2.

[0072] According to the switch connector 10, it is easy to identify the solder 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 72a. In addition, the second opening OP2 is provided across the planar portion 71 and the leg 72b. Thereby, the states inside the first opening OP1 and the second opening OP2 can be photographed from above using a camera or the like. Therefore, according to the switch connector 10, it is easy to identify the solder that has entered the external connection terminal 15 from the first opening OP1 and the second opening OP2.

[0073] In addition, according to the switch connector 10, the switch connector 10 can be made more firm. More specifically, the first opening OP1 is provided across the planar portion 71 and the leg 72a. In addition, the second opening OP2 is provided across the planar portion 71 and the leg 72b. Thereby, the first opening OP1 and the second opening OP2 are each enlarged. Therefore, the amount of solder remaining around the first opening OP1 and the second opening OP2 can be increased. Thereby, the bonding area between the first resin housing 11 formed by the solder and the external connection terminal 15 can be further increased. Therefore, according to the switch connector 10, the switch connector 10 can be made more firm.

[0074] In addition, according to the switch connector 10, the switch connector 10 can be made more secure. More specifically, the protrusion 22a has an inclined surface S5 that is inclined with respect to the vertical direction when viewed in the left-right direction. Therefore, compared with the case where the protrusion 22a does not have the inclined surface S5, the contact area between the protrusion 22a and the molten solder can be increased. As a result, when the molten solder solidifies, the protrusion 22a and the external connection terminal 15 are bonded more firmly. In addition, the protrusion 22b has an inclined surface S6 that is inclined with respect to the vertical direction when viewed in the left-right direction. Therefore, compared with the case where the protrusion 22b does not have the inclined surface S6, the contact area between the protrusion 22b and the molten solder can be increased. As a result, when the molten solder solidifies, the protrusion 22b and the external connection terminal 15 are bonded more firmly. Therefore, according to the switch connector 10, the switch connector 10 can be made more secure.

[0075] According to the switch connector 10, the insertion of the cylindrical portion 51 of the second resin housing 14 into the second through-hole H2 of the external connection terminal 15 can be unimpeded. More specifically, the cylindrical portion 51 of the second resin housing 14 is inserted into the second through-hole H2 of the external connection terminal 15. Therefore, no uneven portion is formed around the second through-hole H2 on the inner surface IS of the external connection terminal 15. As a result, the uneven portion does not impede the insertion of the cylindrical portion 51 into the second through-hole H2. As a result, according to the switch connector 10, the insertion of the cylindrical portion 51 of the second resin housing 14 into the second through-hole H2 of the external connection terminal 15 can be unimpeded.

[0076] According to the switch connector 10, the fixing of the movable terminal 30 can be further suppressed. 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 solder provided at the ends of the legs 72a and 72b enters the external connection terminal 15 through the first opening OP1 and the second opening OP2, respectively, the molten solder can be retained by the plurality of first grooves G1. Therefore, according to the switch connector 10, the fixing of the movable terminal 30 can be further suppressed.

[0077] [First Modified Example]

[0078] Hereinafter, the switch connector 10a according to the first modified example of the present invention will be described with reference to the drawings. Figure 6 is a perspective view of the external connection terminal 15 of the switch connector 10a. In addition, in Figure 6 for the sake of explanation, the external connection terminal 15 before the bending process is shown. In addition, in Figure 6 only the representative first recess R1 among the plurality of first recesses R1 is labeled with a reference numeral. In addition, for the switch connector 10a according to the first modified example, only the parts different from the switch connector 10 according to the first embodiment will be described, and the rest will be omitted.

[0079] As Figure 6 shown, the difference between the switch connector 10a and the switch connector 10 is that a plurality of first recesses R1 are formed on the inner surface IS of the main body portion 62. The plurality of first recesses R1 are respectively recessed in a manner that bends toward the outside of the switch connector 10. The plurality of first recesses R1 respectively correspond to the "concavo-convex portions" in the technical solution.

[0080] In the switch connector 10a as described above, the same effect as that of the switch connector 10 is also achieved.

[0081] [Second Modified Example]

[0082] Hereinafter, the switch connector 10b according to the second modified example of the present utility model will be described with reference to the drawings.

In addition, in Figure 7 , for the sake of explanation, the external connection terminal 15 before the bending process is shown. In addition, in Figure 7 , only the representative first groove G1 among the plurality of first grooves G1 is labeled with a reference numeral. In addition, for the switch connector 10b according to the second modified example, only the parts different from the switch connector 10 according to the first embodiment will be described, and the rest will be omitted.

[0083] As Figure 7 shown, the difference between the switch connector 10b and the switch connector 10 is that the plurality of first grooves G1 extend in the left-right direction. In this modified example, the plurality of first grooves G1 are not connected to each other. In addition, a part of the plurality of first grooves G1 may also be connected to each other.

[0084] In the switch connector 10b as described above, the same effect as that of the switch connector 10 is also achieved. In addition, according to the switch connector 10b, the fixing of the movable terminal 30 can be further suppressed. More specifically, the plurality of first grooves G1 extend in the left-right direction. Thus, the movement of the molten solder remaining in the plurality of first grooves G1 in a direction other than the left-right direction is blocked by the plurality of first grooves G1. Therefore, it is possible to suppress the molten solder from entering the central portion of the switch connector 10b as viewed in the up-down direction by the plurality of first grooves G1. Therefore, according to the switch connector 10b, the fixing of the movable terminal 30 can be further suppressed.

[0088] More specifically, as Figure 8 shown, a plurality of second grooves G2 are formed in a net shape on the upper surface S1 of the first resin housing 11. In this modification, a plurality of second grooves G2 are also formed in a net shape on the upper surfaces of the support portions 23a, 23b, and 24. In addition, the plurality of second grooves G2 may not be formed on the upper surfaces of the support portions 23a, 23b, and 24.

[0089] In addition, it is sufficient that a plurality of second grooves G2 are formed in a net shape on the upper surface S1 or the lower surface S2 of the first resin housing 11.

[0090] In the switch connector 10c as described above, the same effects as those of the switch connector 10 are also achieved. In addition, according to the switch connector 10c, the fixing of the movable terminal 30 can be further suppressed. More specifically, a plurality of second grooves G2 are formed in a net shape on the upper surface S1 or the lower surface S2 of the first resin housing 11. Thus, even if the molten fluxes provided at the ends of the legs 72a and 72b enter the external connection terminals 15 through the first opening OP1 and the second opening OP2 respectively and flow onto the upper surface S1 or the lower surface S2 of the first resin housing 11, the molten fluxes can be retained by the plurality of second grooves G2. Therefore, according to the switch connector 10c, the fixing of the movable terminal 30 can be further suppressed.
