Description

[Technical Field]

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

[0002] The shielded connector of Patent Document 1 includes contacts, a housing, and a shielding member. A plurality of locking pieces are formed to protrude from the outer peripheral surface of the shielding member. The shielded connector of Patent Document 2 includes an inner conductor, an outer conductor, and a shielding member. The outer conductor has an arc-shaped press-fit portion. The press-fit portion is formed with a lance portion consisting of a cut-and-raised piece. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2008-192498 [Patent Document 2] Japanese Patent Application Laid-Open No. 2009-64716 Summary of the Invention [Problem to be solved by the invention]

[0004] When a shielded connector is installed on a circuit board, the outer conductor may also cover the circuit board side of the inner conductor to prevent a decrease in shielding performance. A die-cast outer shell may be used to cover the circuit board side of the inner conductor. It is not easy to integrally mold the outer shell and the tubular connecting portion. For this reason, a through hole may be formed in the outer shell, and a separate outer conductor tube including the tubular connecting portion may be inserted into the through hole for assembly. A configuration may be adopted in which a press-fitting blade corresponding to the locking piece in Patent Document 1 and the lance portion in Patent Document 2 is formed on the outer conductor tube, and the press-fitting blade is engaged with the inner surface of the through hole in the outer shell. However, if an external force is applied to the outer conductor tube when it is assembled to the outer shell, the axial center of the outer conductor tube may be misaligned, resulting in misalignment. It is difficult to prevent this misalignment using only the press-fitting blade.

[0005] Therefore, an object of the present disclosure is to provide a shielded connector that can suppress loss of alignment of the outer conductor tube. [Means for solving the problem]

[0006] The shielded connector of the present disclosure comprises an inner conductor, an outer conductor surrounding the inner conductor, and a dielectric disposed between the inner conductor and the outer conductor, wherein the outer conductor has a cylindrical outer conductor tube and an outer shell body, the outer shell body having a through hole in which the outer conductor tube is disposed, the outer conductor tube having press-fitting blades that protrude radially outward and engage with the inner surface of the through hole of the outer shell body, and holding protrusions that protrude radially outward and contact the inner surface of the through hole of the outer shell body, the press-fitting blades are disposed at both radial ends of the outer conductor tube, and the holding protrusions are disposed on the outer conductor tube at positions circumferentially offset from the press-fitting blades when the outer conductor tube is viewed axially. [Effects of the Invention]

[0007] According to the present disclosure, it is possible to provide a shielded connector that can suppress loss of alignment of the outer conductor tube. [Brief explanation of the drawings]

[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The shielded connector of the present disclosure comprises: (1) An electrical wiring board comprising an inner conductor, an outer conductor surrounding the inner conductor, and a dielectric disposed between the inner conductor and the outer conductor, wherein the outer conductor has a cylindrical outer conductor tube and an outer shell body, the outer shell body having a through hole in which the outer conductor tube is disposed, the outer conductor tube having a press-fitting blade protruding radially outward and engaging with the inner peripheral surface of the through hole of the outer shell body, and a holding protrusion protruding radially outward and contacting the inner peripheral surface of the through hole of the outer shell body, the press-fitting blades being disposed at both radial ends of the outer conductor tube, and the holding protrusions being disposed at positions on the outer conductor tube that are circumferentially offset from the press-fitting blades when the outer conductor tube is viewed axially.

[0010] When the outer conductor tube is assembled to the outer shell, the press-fitting blades formed on both radial ends of the outer conductor tube are engaged with the inner circumferential surface of the through-hole of the outer shell, and the holding protrusions are in contact with the inner circumferential surface of the through-hole of the outer shell at positions circumferentially offset from the press-fitting blades when viewed axially. This configuration therefore maintains the axial center of the outer conductor tube and prevents the outer conductor tube from becoming misaligned. "Misalignment" in this case refers to a state in which the axial centers of the outer conductors do not coincide when connecting the outer conductor to the mating outer conductor, potentially resulting in misalignment.

[0011] (2) It is preferable that the holding projection is disposed at a position on the outer conductor tube that is offset from the press-fitting blade in the axial direction. According to the above configuration, it is possible to prevent the outer conductor tube from being tilted in the axial direction relative to the outer shell.

[0012] (3) Preferably, a plurality of the holding projections are arranged at intervals in the circumferential direction on the outer conductor tube.

[0013] The above configuration can highly reliably prevent the outer conductor tube from becoming misaligned.

[0014] (4) The holding projections may be disposed at the top, bottom, left and right positions on the outer peripheral surface of the outer conductor tube when viewed in the axial direction.

[0015] The above-mentioned configuration can prevent the outer conductor tube from losing alignment in all four directions, i.e., up, down, left, and right.

[0016] (5) A housing made of synthetic resin is provided which is connected to the outer conductor, and the housing has an insertion hole in which the end of the outer conductor tube which has passed through the through hole is placed, and a housing-side holding protrusion which protrudes from the inner surface of the insertion hole and contacts the outer surface of the end of the outer conductor tube, and it is preferable that a plurality of the housing-side holding protrusions are arranged at intervals in the circumferential direction on the housing.

[0017] In the above configuration, the housing-side retaining protrusions can be in compressed or crushed contact with the outer peripheral surface of the outer conductor tube, thereby increasing the dimensional tolerance between the housing and the outer conductor. In addition, the contact of the housing-side retaining protrusions spaced apart in the circumferential direction with the outer peripheral surface of the end of the outer conductor tube can correct misalignment of the axial center of the end of the outer conductor tube.

[0018] [Details of the embodiments of the present disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0019] <Embodiment 1> The shielded connector 10 according to the first embodiment is a shielded connector for a board that is installed on a circuit board 200. As shown in Figures 1 and 2, the shielded connector 10 includes inner conductors 11 and 12, outer conductors 13, 14, and 15 that surround the outer peripheries of the inner conductors 11 and 12, dielectrics 16 and 17 that are disposed between the inner conductors 11 and 12 and the outer conductors 13, 14, and 15, and a housing 18 to which the outer conductors 13, 14, and 15 are connected.

[0020] The outer conductors 13, 14, and 15 and the inner conductors 11 and 12 are conductive materials such as metal. The dielectrics 16 and 17 and the housing 18 are insulating materials such as synthetic resin. The housing 18 is mated with the mating connector 300. In the following description, the front side of the housing 18, which faces the mating connector 300 when mated, is referred to as the front. In the up-down direction, the side on which the shielded connector 10 is installed relative to the circuit board 200 is referred to as the upper side. The upper side in Figures 1 and 2 is the upper side. In Figures 1 and 2, the upper side is indicated by the symbol "U" and the front side is indicated by the symbol "F." In the following description, the up-down direction is synonymous with the height direction, and the front-to-back direction is synonymous with the axial direction. The left-to-right direction is a direction intersecting the up-to-down and front-to-back directions and is synonymous with the width direction.

[0021] (housing) 11, the housing 18 has an overall rectangular outer shape and includes a housing main body 19 and a hood 21 that protrudes forward from the housing main body 19. As shown in FIGS. 14 and 15, the housing main body 19 has multiple insertion holes 22 that penetrate in the front-to-rear direction, four in this embodiment 1. Each insertion hole 22 has a circular cross section and is arranged in an upper-lower pair next to each other in the width direction.

[0022] 15, a fitting recess 23 is formed on the rear surface of the housing body 19, with the shape recessed except for the central portion of the housing body 19. A plurality of inner recess ribs 24 are formed on the inner peripheral surface of the fitting recess 23.

[0023] The housing main body 19 has a plurality of housing-side retaining protrusions 108 on the inner peripheral surface of each insertion hole 22. Each housing-side retaining protrusion 108 has an arc-shaped cross section and is formed to extend the entire length of each insertion hole 22. Each housing-side retaining protrusion 108 is provided on the inner peripheral surface of the respective insertion hole 22 at four locations, at equal intervals in the circumferential direction, namely the upper right, lower right, upper left, and lower left when viewed from the axial direction.

[0024] 2, the front end of the outer conductor tube 15, which will be described later, is inserted into the insertion hole 22 of the housing body 19. As shown in FIG. 5, each housing-side holding protrusion 108 comes into contact with the outer peripheral surface of the outer conductor tube 15.

[0025] As shown in Fig. 15, a punched recess 26 is formed in the upper end of the housing main body 19. The punched recess 26 is formed as a result of removing a mold (not shown) that forms a housing locking portion 36 (described later). In addition, a pair of fitting holes 27 are formed in the upper end of the housing main body 19 on both the left and right sides of the punched recess 26. As shown in Fig. 2, the fitting holes 27 penetrate the upper end of the housing main body 19 in the front-rear direction and communicate with the inside of the hood 21.

[0026] 15, a pair of first locking projections 28 are formed at the rear end of the housing body 19, protruding into each fitting hole 27. Each first locking projection 28 faces the rear surface of the housing body 19 and protrudes toward the fitting recess 23. As shown in FIG. 2, a first connecting projection 43 of the outer shell 13, which will be described later, comes into contact with and locks onto the front surface of the first locking projection 28.

[0027] 15 and 16, the housing main body 19 has a pair of housing side portions 31 that separate the left and right sides of the fitting recess 23. A pair of second locking projections 32 are formed on the inner surface (facing surfaces) of the lower end of each housing side portion 31 so as to protrude toward the fitting recess 23.

[0028] 16, a pair of fitting grooves 34 are formed between each second locking projection 32 and the rear surface of the fitting recess 23. Each fitting groove 34 is open in the vertical direction and inward in the width direction (toward the center of the housing 18 in the width direction) between each second locking projection 32 and the rear surface of the fitting recess 23.

[0029] 13, a second connecting protrusion 76 of the board-side shell body 14 (described later) is inserted from below into the fitting groove 34 of the housing main body 19. The second connecting protrusion 76 of the board-side shell body 14 (described later) comes into pressing contact with the front surface of the second locking protrusion 32.

[0030] The hood 21 has a rectangular cylindrical shape. As shown in FIG. 2, the mating connector 300 is inserted into and fitted to the hood 21. As shown in FIG. 14, the hood 21 is formed with a pair of protruding pieces 35 that protrude forward from the front surface of the housing main body 19. Each protruding piece 35 is inserted into a space 301 (see FIG. 1) formed in the mating connector 300. A housing locking portion 36 that locks the mating connector 300 is formed on the upper wall of the hood 21. The housing locking portion 36 locks the mating connector 300, thereby maintaining the housing 18 and the mating connector 300 in a mated state.

[0031] (Outer conductor) As shown in Figure 2, the outer conductor is composed of an outer shell 13, a board-side outer shell 14, and multiple outer conductor tubes 15. The outer shell 13 and the board-side outer shell 14 are conductive rigid bodies made of die-cast zinc alloy, aluminum alloy, or the like, and are formed from the same material. The outer shell 13 and the board-side outer shell 14 are assembled together to form a single housing. The outer conductor tube 15 is a press-formed body formed by bending a metal plate made of a material, such as brass, that is harder than the outer shell 13 and the board-side outer shell 14.

[0032] 17 and 18, the outer shell body 13 has an upper portion 37 that is rectangular in plan view, and a pair of side portions 38 that protrude downward from both the left and right ends of the upper portion 37. A fitting receiving portion 39 is formed between the upper portion 37 and each side portion 38. The fitting receiving portion 39 is open downward and rearward on the outer shell body 13.

[0033] As shown in Figure 18, the outer shell body 13 has mounting portions 41 that are connected to the top 37 and each side portion 38 and have a padded shape on the fitting receiving portion 39 side. The mounting portions 41 close the front surface of the outer shell body 13. As shown in Figure 17, a plurality of tubular portions 42 protrude from the front surface of the outer shell body 13. The tubular portions 42 are arranged side by side on both the top and bottom sides and in the width direction. The tubular portions 42 are connected to each other on the top, bottom, left, and right sides and have a shape that can fit into the fitting recess 23.

[0034] The outer shell 13 has a pair of first connecting projections 43 that project upward from each upper cylindrical portion 42. The upper end side of each first connecting projection 43 projects upward beyond the upper portion 37.

[0035] A press-fit recess 45 is formed at the lower end of the front surface of the outer shell body 13. The press-fit recess 45 is located between the lower tubular portions 42. Specifically, the press-fit recess 45 is defined by the lower tubular portions 42 and the connecting portions that connect the lower tubular portions 42 in the width direction, and is open forward and downward. The rear of the press-fit recess 45 is closed by the front surface of the outer shell body 13. The press-fit recess 45 has a dovetail shape that gradually increases in width from the lower end on the opening side toward the upper end on the back side. A press-fit protrusion 75 (described later) of the substrate-side outer shell body 14 is press-fitted into the press-fit recess 45 (see FIG. 8).

[0036] As shown in Fig. 18, the mounting portion 41 has a plurality of through holes 46 penetrating therethrough in the front-rear direction. Each through hole 46 has a circular cross section, and as shown in Fig. 17, the front end portion is formed inside each tubular portion 42. When the outer shell body 13 and the housing 18 are connected, each tubular portion 42 fits into the fitting recess 23 of the housing 18, and as shown in Fig. 2, the through holes 46 of the mounting portion 41 and the insertion hole 22 of the housing main body 19 communicate in the front-rear direction.

[0037] As shown in Figure 18, an engagement protrusion 47 that protrudes toward the fitting-receiving portion 39 is formed in the widthwise center of the outer shell 13. The engagement protrusion 47 has a plate shape that extends vertically in the mounting portion 41 and is disposed between adjacent through-holes 46 in the widthwise direction. The lower end of the engagement protrusion 47 is stepped (see Figure 8). The upper through-holes 46 in the mounting portion 41 correspond to the stepped shape of the lower end of the engagement protrusion 47 and are formed longer rearward than the lower through-holes 46 (see Figure 2).

[0038] As shown in Fig. 18, each through hole 46 opens to an end face 109 that faces rearward within the fitting-receiving portion 39. As shown in Fig. 19, the end face 109 into which the upper through holes 46 open is located further rearward than the end face 109 into which the lower through holes 46 open.

[0039] As shown in FIG. 19 , a pair of kerfs 111 are formed in the end face 109 of the mounting portion 41. The kerfs 111 are cut forward from the lower left and right side edges of the rear opening edge of the through hole 46. A groove portion 51, which will be described later, is disposed between each kerf 111. The outer shell body 13 has a stopper portion 112 that closes the front end of each kerf 111 in each through hole 46. The stopper portion 112 is disposed on the front side of each kerf 111 and extends in the up-down direction, similar to the end face 109. The outer shell body 13 also has a restricting portion 113 that closes the outer side of each kerf 111 in the width direction in each through hole 46. The restricting portion 113 is a part of the inner surface of the side portion 38, is disposed in the front-to-rear direction, and has its front end intersecting the stopper portion 112. The stopper portion 112 is capable of abutting and stopping the protrusion portion 95 of the outer conductor tube 15, which will be described later (see Figure 7), and the restricting portion 113 is capable of restricting the rotation of the outer conductor tube 15 within the through-hole 46 (see Figure 6).

[0040] As shown in Fig. 18, the outer shell 13 has a plurality of grooves 51 formed therein. Each groove 51 is formed by cutting out the lower portion (including the stepped portion) of the peripheral wall surrounding each through-hole 46 in the mounting portion 41, and is further recessed into the inner surface of the rear end portion of the upper portion 37. Each groove 51 is disposed for each through-hole 46, and is open downward and rearward toward the fitting-receiving portion 39. Each groove 51 in the lower portion of the peripheral wall opens to the end face 109.

[0041] 12 and 13, four legs 54 are formed to protrude downward from the front and rear ends of the lower end of each side portion 38. The legs 54 are arranged to correspond to the four corners of the lower end of the outer shell 13. As shown in FIGS. 2 and 9, the legs 54 are positioned and inserted into fixing holes 201 of the circuit board 200.

[0042] As shown in Fig. 18, a pair of recesses 56 are formed in the rear lower end of the inner surface of each side portion 38 (which is also the inner surface of the fitting receiving portion 39). Each recess 56 is open inward in the width direction (the side where each side portion 38 faces each other) and rearward. As shown in Fig. 9, each recess 56 is fitted with a protrusion 72 of the board-side shell body 14, which will be described later.

[0043] 12 and 13, the board-side shell body 14 is assembled to the shell body 13 from below. As shown in Fig. 21, the board-side shell body 14 has a rectangular bottom portion 59 in bottom view, a back portion 61 rising from the rear end of the bottom portion 59, a rising portion 62 rising from a position near the rear end of the bottom portion 59, and a partition portion 63 connecting the back portion 61 and the rising portion 62 in the center of the width of the bottom portion 59. The back portion 61, the rising portion 62, and the partition portion 63 are configured as a fitting portion that can fit into the fitting receiving portion 39 of the shell body 13.

[0044] The back portion 61 and the rising portion 62 form a rectangular vertical wall in rear view. As shown in Fig. 9, the back portion 61 closes the rear surface of the outer shell body 13. As shown in Figs. 20 and 21, the protruding dimension of the rising portion 62 is smaller than the protruding dimension of the back portion 61. The height difference between the upper end surface of the rising portion 62 and the upper end surface of the back portion 61 corresponds to the height difference of the stepped shape of the mounting portion 41. The upper end surface of the rising portion 62 and the upper end surface of the partition portion 63 are connected at the same height.

[0045] 21, a groove 52 is formed in the widthwise center of the substrate-side shell 14. The groove 52 is formed as a stepped continuous recess on the top and front surfaces of the back portion 61, the partition portion 63, the rising portion 62, and the bottom portion 59.

[0046] The groove 52 has a plurality of contact ribs 65 extending in the vertical direction on both sides facing each other in the width direction. Each contact rib 65 has an arc-shaped cross section. A large number of contact ribs 65 are formed at intervals in the front-to-rear direction on both sides of the groove 52 corresponding to the back portion 61, the partition portion 63, the rising portion 62, and the bottom portion 59.

[0047] A pair of engaging protrusions 49 is formed on each of the upper surfaces of the back portion 61, the rising portion 62, and the bottom portion 59, on both left and right sides of the groove portion 52. Contact ribs 66 extending in the vertical direction are also formed on both side surfaces of each engaging protrusion 49.

[0048] When the outer shell 13 and the board-side shell 14 are assembled, the lower end of the engaging protrusion 47 of the outer shell 13 fits into the groove 52 of the board-side shell 14 (see FIG. 8). Furthermore, as partially shown in FIG. 9, each engaging protrusion 49 of the board-side shell 14 fits into each groove 51 of the outer shell 13. Each contact rib 65, 66 of the board-side shell 14 contacts the outer surface of the engaging protrusion 47 of the outer shell 13 and the inner surface of each groove 51. Furthermore, as shown in FIGS. 20 and 21, each of the back portion 61 and the rising portion 62 has a contact rib 67 formed on both side surfaces thereof, extending vertically. This contact rib 67 contacts the inner surface of each side portion 38 of the outer shell 13 (see FIG. 9).

[0049] As shown in Figure 20, the board-side shell body 14 has a pair of protrusions 72 at the lower rear ends of both sides. Each protrusion 72 has an arc-shaped cross section that extends in the front-to-rear direction on both sides of the bottom portion 59. The front end of each protrusion 72 is integrally connected to the lower end of each contact rib 67 formed on both sides of the back portion 61. When the shell body 13 and the board-side shell body 14 are assembled, as shown in Figure 9, the protrusions 72 fit into the lower portion of the recessed portion 56, and the lower surfaces of the protrusions 72 come into compressed or crushed contact with the lower surface of the recessed portion 56.

[0050] 20 and 21, a press-fit protrusion 75 is formed protruding from the center in the width direction on the upper surface of the front end of the bottom portion 59. The press-fit protrusion 75 is columnar and has a constant cross-sectional shape in the vertical direction except for the upper end. A pair of contact ribs 68 extending in the vertical direction is also formed on both side surfaces of the press-fit protrusion 75. Each contact rib 68 contacts the inner surface of the press-fit recess 45.

[0051] The board-side shell 14 has a pair of second connecting protrusions 76 that protrude outward in the width direction from the front ends of both side surfaces of the bottom 59. A pressing rib 78 with an arc-shaped cross section that extends vertically is formed on the rear surface of each second connecting protrusion 76. The pressing rib 78 of the second connecting protrusion 76 comes into pressing contact with the front surface of the second locking projection 32 (see FIG. 13).

[0052] As shown in FIG. 21 , multiple openings 81 are formed in the board-side shell body 14. Each opening 81 has a rectangular cross section and is located on both the left and right sides of the groove 52, as well as in the front and rear of the board-side shell body 14. Each front opening 81 is located in front of the rising portion 62 and behind the engaging protrusion 49 formed on the bottom portion 59, and penetrates the bottom portion 59 to open to the bottom surface 92 (the surface facing downward; see FIG. 12 ). Each rear opening 81 is defined by the back portion 61, the rising portion 62, and the partition portion 63, and similarly penetrates the bottom portion 59 to open to the bottom surface 92. The partition portion 63 separates adjacent rear openings 81 in the width direction.

[0053] 2, dielectrics 16, 17 are fitted into the respective openings 81. The inner conductors 11, 12 attached to the dielectrics 16, 17 cause a board connection portion 107 (described later) to protrude downward from the bottom surface 92 of the bottom portion 59 through the openings 81. The board connection portion 107 is inserted into a connection hole 202 formed in the circuit board 200 and is electrically connected to a conductive portion (not shown).

[0054] 13, a plurality of mounting portions 84 to 87 are formed on the bottom surface 92 of the bottom portion 59 so as to surround the periphery of each opening 81. Each of the mounting portions 84 to 87 slightly protrudes downward from the bottom surface 92 of the bottom portion 59. The lower end surface of each of the mounting portions 84 to 87 is flat and is electrically connected by soldering to a conductive portion for grounding of the circuit board 200.

[0055] Specifically, each mounting portion has a front mounting portion 84 extending in the left-right direction in front of each front opening 81, side mounting portions 85 extending in the front-rear direction on both the left and right sides of each opening 81, and a shared mounting portion 86 extending in the left-right direction between the front opening 81 and the rear opening 81. In addition, complementary mounting portions 87 are formed as mounting portions on both the left and right sides of a recessed portion 91, which will be described later.

[0056] A retraction recess 88 is recessed into the rear end of the bottom surface 92 of the bottom portion 59. The rear end of the retraction recess 88 opens into a rear surface 93 that intersects with the bottom surface 92 of the substrate-side outer shell body 14. The retraction recess 88 has a rectangular cross section, communicates with the opening 81 at the front, is open to the rear and downward, and is closed at the top by the back portion 61.

[0057] The retraction recess 88 is disposed above the surface wiring (not shown) of the circuit board 200. The retraction recess 88 prevents the board-side outer shell 14 from being electrically connected to the surface wiring.

[0058] The complementary mounting portion 87 corresponds to each of the retraction recesses 88 and is formed to extend in the front-to-rear direction along the inner side edge of each of the retraction recesses 88 that is located toward the center of the width of the bottom portion 59.

[0059] As shown in Fig. 13, a recess 91 is recessed in the widthwise center of the back surface 93 of the board-side shell body 14. As shown in Fig. 9, the recess 91 is formed on the back surface 93 of the board-side shell body 14 so as to extend in the vertical direction from the bottom portion 59 to the spine portion 61. The recess 91 is recessed across the bottom surface 92 and back surface 93 of the board-side shell body 14, and is open rearward and downward.

[0060] The recessed portion 91 penetrates the back portion 61 and is defined inside the partition portion 63. That is, the recessed portion 91 is formed within the thickness range of the partition portion 63. As shown in FIG. 8, the innermost surface 126 and the inner upper surface 127 of the recessed portion 91 are arranged inside the groove portion 52 and parallel to the groove portion 52. The portion of the partition portion 63 between the recessed portion 91 and the groove portion 52 (see symbol a in FIG. 8) is formed with a uniform or nearly uniform thickness from the back portion 61 to the bottom portion 59. The thickness of the partition portion 63 is reduced in the area corresponding to the recessed portion 91. As shown in FIG. 13, the complementary mounting portion 87 is arranged on the bottom surface 92 of the bottom portion 59 so as to be sandwiched in the width direction between the retracted recess 88 and the recessed portion 91. The side mounting portion 85 located on the inner side in the width direction (the center side in the width direction) is arranged so as to be visible through the recessed portion 91 when the board-side shell body 14 is viewed from behind, as shown in FIGS.

[0061] The outer conductor tube 15 is integrally formed by bending a conductive metal plate, and is thinner than both the outer shell 13 and the substrate-side outer shell 14. As shown in Fig. 22, the outer conductor tube 15 has a cylindrical tubular connecting portion 94 extending in the front-to-rear direction, and a pair of protrusions 95 protruding downward from both the left and right sides of the rear end of the tubular connecting portion 94. The tubular connecting portion 94 is formed by bending a plate material into a circle, and as shown in Fig. 23, has a butting edge 116 at the lower end where both circumferential ends are butted together.

[0062] Each protrusion 95 has a tapered shape that widens downward from both the left and right ends of the upper half of the rear end of the tubular connecting portion 94. The protrusions 95 are rectangular in side view. An embossed contact protrusion 117 that bulges outward is formed near the bottom end of each protrusion 95. The contact protrusion 117 has an arc-shaped cross section.

[0063] Furthermore, press-fit blades 118 are formed in the front-rear intermediate portion of the cylindrical connecting portion 94. The press-fit blades 118 are formed in pairs at both left and right ends (both radial ends) of the cylindrical connecting portion 94, and are formed in a shape that bulges outward in front of slits 119 that extend in the up-down direction (which is also the circumferential direction of the cylindrical connecting portion 94). Specifically, as shown in FIG. 22 , the press-fit blades 118 have an arc-shaped cross section and are triangular in shape in a side view with the up-down dimension decreasing toward the front. As shown in FIG. 3 , each press-fit blade 118 is press-fitted into the inner circumferential surface of the through-hole 46 of the outer shell 13 and locked therein.

[0064] Furthermore, inner protrusions 120 are formed in the front-rear intermediate portion of the cylindrical connecting part 94. As shown in Fig. 23, each inner protrusion 120 is formed in a pair on both the left and right ends of the cylindrical connecting part 94, and is formed in a shape that bulges inward behind a slit 119 that extends in the up-down direction (which is also the circumferential direction of the cylindrical connecting part 94). Each inner protrusion 120 is engaged with the outer surfaces of the dielectrics 16, 17 arranged inside the cylindrical connecting part 94 (see Fig. 3).

[0065] 22, the cylindrical connecting portion 94 has a plurality of holding protrusions 121 formed in a region rearward of the press-fitting blade 118 and forward of the protrusion 95. Each holding protrusion 121 has an embossed shape that bulges outward from the cylindrical connecting portion 94, and is formed so as to extend with a constant cross-sectional shape (arcuate) in the front-rear direction.

[0066] As shown in FIG. 23 , four retaining protrusions 121 are provided on the outer peripheral surface of the tubular connecting portion 94 at regular intervals in the circumferential direction. The press-fitting blades 118 protrude from the outer peripheral surface of the tubular connecting portion 94 by a larger amount than the retaining protrusions 121. When the tubular connecting portion 94 is viewed from the axial direction (the front or rear, i.e., the thickness direction of the paper in FIG. 23 ), the retaining protrusions 121 are circumferentially offset from the press-fitting blades 118. Specifically, the retaining protrusions 121 are located at four positions: the upper right, lower right, upper left, and lower left, which correspond to the top, bottom, left, and right positions when the tubular connecting portion 94 is viewed from the front. The retaining protrusion 121 at the lower right in FIG. 23 is located near the abutting edge 116 of the tubular connecting portion 94. As shown in FIG. 4 , each retaining protrusion 121 contacts the inner peripheral surface of the through-hole 46 of the outer shell 13.

[0067] The outer conductor tube 15 is inserted into the through-hole 46 of the outer shell body 13 from the rear. A plurality of outer conductor tubes 15 (four in the first embodiment) are provided corresponding to the respective through-holes 46, and as shown in Fig. 1, each of them is formed in the same shape. The outer conductor tube 15 is held in place in the outer shell body 13 by the protrusions 95 being stopped by the stopper portions 112 and the press-fitting blades 118 being locked onto the inner circumferential surfaces of the through-holes 46 (see Fig. 7). The front end of the cylindrical connecting portion 94 of the outer conductor tube 15 is disposed in the shielded connector 10 so as to protrude from the cylindrical portion 42 of the outer shell body 13 into the hood 21 (see Fig. 2).

[0068] (dielectric) As shown in Fig. 1, the dielectrics 16, 17 have a cylindrical main body 101 extending in the front-rear direction and an extended portion 102 protruding downward from the rear end of the main body 101, and are formed in an L-shape in side view. Horizontal portions 104 (described later) of the inner conductors 11, 12 are inserted into the main body 101. A guide groove 103 (described later) is formed on the rear surface of the extended portion 102 and extends in the up-down direction. The guide groove 103 is open rearward. Extended portions 105 (described later) of the inner conductors 11, 12 are fitted into the guide groove 103 from behind (see Figs. 2 and 7).

[0069] The main body portions 101 of the dielectrics 16, 17 are inserted into the cylindrical connecting portion 94 of the outer conductor tube 15 and are arranged in the through-hole 46 of the outer shell body 13. The lead-out portions 102 of the dielectrics 16, 17 are inserted into the opening 81 of the substrate-side outer shell body 14.

[0070] As shown in Fig. 1, the dielectric is composed of two types of dielectrics, long and short, 16 and 17. The long dielectric 16 is held by the outer conductors 13, 14, and 15 with its main body 101 placed in the upper through-hole 46 and its lead-out portion 102 inserted into the rear opening 81. The short dielectric 17 is held by the outer conductors 13, 14, and 15 with its main body 101 placed in the lower through-hole 46 and its lead-out portion 102 inserted into the front opening 81.

[0071] (inner conductor) As shown in FIG. 1 , the inner conductors 11 and 12 are pin-shaped terminals each having a horizontal portion 104 extending in the front-rear direction and an extending portion 105 extending downward from the rear end of the horizontal portion 104, and are formed in an L-shape in a side view. When inserted into the main body 101 of the dielectric 16 or 17, the horizontal portion 104 has a mating connection portion 106 that protrudes forward from the main body 101. As shown in FIG. 2 , the mating connection portion 106 protrudes into the hood 21 and is electrically connected to the mating inner conductor 303 when the housing 18 and the mating connector 300 are mated. When inserted into the guide groove 103 of the leading portion 102 of the dielectric 16 or 17, the extending portion 105 has a board connection portion 107 that protrudes downward from the leading portion 102. The board connection portion 107 is formed with a smaller diameter than the upper portion of the extending portion 105.

[0072] As shown in Figure 1, the inner conductor is composed of two types of inner conductors, long and short, 11 and 12. The long inner conductor 11 is held by a long dielectric 16. The short inner conductor 12 is held by a short dielectric 17.

[0073] (Assembly method and operation of shielded connector) First, the horizontal portions 104 of each of the inner conductors 11, 12 are inserted from the rear into the main body portions 101 of the corresponding dielectrics 16, 17 and held therein. The extending portions 105 of the inner conductors 11, 12 are inserted into the guide grooves 103 and arranged exposed on the rear surface side of the drawn-out portion 102. Next, the main body portions 101 of each of the dielectrics 16, 17 are inserted from the rear into the cylindrical connecting portions 94 of the corresponding outer conductor tubes 15 and held therein. Then, the cylindrical connecting portions 94 of each of the outer conductor tubes 15 are inserted from the rear into the through-holes 46 of the corresponding outer shell 13 and held therein.

[0074] At the final stage of the insertion process of the cylindrical connecting part 94, each protrusion 95 enters each cut groove 111 from the rear, and the contact protrusion 117 of each protrusion 95 slides along the restricting part 113. At this time, each protrusion 95 is elastically deformed inward in the width direction (toward the center of the width direction of the outer conductor tube 15) with the connection part with the cylindrical connecting part 94 as a fulcrum.

[0075] When the cylindrical connecting portion 94 is properly inserted into the through-hole 46 of the outer shell body 13, the front end (thickness portion) of each protrusion 95 abuts against the stopper portion 112 of the outer shell body 13 (see FIG. 7), restricting further insertion of the outer conductor tube 15. Each protrusion 95 remains in an elastically deformed state, bringing each contact protrusion 117 into firm contact with the restricting portion 113 (see FIG. 6). The outer conductor tube 15 is assembled to the outer shell body 13 in a state where rattle is restricted by the locking action of the protrusions 95 with respect to the outer shell body 13 and the holding action of the press-fitting blades 118 and each holding protrusion 121, which will be described later.

[0076] In the case of the first embodiment, since the outer conductor tube 15 is assembled to the outer shell body 13 from the rear, it is possible to easily form a structure for preventing the outer conductor tube 15 from slipping out from the front by the stopper portion 112. In particular, the direction in which the outer conductor tube 15 is inserted into the outer shell body 13, the direction in which the inner conductors 11 and 12 are inserted into the dielectrics 16 and 17, the direction in which the dielectrics 16 and 17 are inserted into the outer conductor tube 15, and, as will be described later, the direction in which the outer shell body 13 is connected to the housing 18 are all rearward and unified in the same direction, which provides excellent assembly properties.

[0077] Furthermore, when the cylindrical connecting portion 94 is properly inserted into the through-hole 46 of the outer shell body 13, the press-fitting blades 118 of the outer conductor tube 15 are engaged so as to bite into both left and right end portions of the inner circumferential surface of the through-hole 46 of the outer shell body 13 in a press-fit state (compressed or crushed state) (see FIG. 3). Furthermore, the holding protrusions 121 of the outer conductor tube 15 firmly contact the upper, lower, left and right portions of the inner circumferential surface of the through-hole 46 of the outer shell body 13 behind the engaging positions of the press-fitting blades 118 (see FIG. 4).

[0078] As shown in FIG. 11 , the front end of the tubular connecting portion 94 is disposed to protrude forward from the tubular portion 42 of the outer shell body 13. If the retaining protrusions 121 were not formed on the tubular connecting portion 94, when an external force acts on the front end of the tubular connecting portion 94 from above or below, the tubular connecting portion 94 would be pressed in the direction of the external force, which could cause the axial center of the tubular connecting portion 94 to become misaligned. In this regard, in the first embodiment, the tubular connecting portion 94 is formed with a plurality of retaining protrusions 121 in addition to the press-fitting blades 118, and the retaining protrusions 121 are arranged circumferentially at intervals at the top, bottom, left, and right positions of the tubular connecting portion 94. Furthermore, because the retaining protrusions 121 are held in contact with the inner circumferential surface of the through-hole 46 of the outer shell body 13, they can resist external forces from above or below, preventing the axial center of the tubular connecting portion 94 from becoming misaligned.

[0079] Next, the outer shell body 13 is connected to the housing 18 from the rear (see FIG. 11). During the connection process of the outer shell body 13, the first connecting protrusion 43 climbs over the first locking projection 28 and engages with the fitting hole 27. When the connection of the outer shell body 13 is complete, the tubular portion 42 contacts the inner surface of the fitting recess 23, stopping the connection operation of the outer shell body 13, and the rear surface of the first connecting protrusion 43 and the front surface of the first locking projection 28 come into contact with each other (see FIG. 2).

[0080] The front end of the tubular connecting portion 94 is inserted into the insertion hole 22 of the housing 18 from the rear. The housing-side holding protrusions 108 contact the outer peripheral surface of the front portion of the tubular connecting portion 94 in a compressed or crushed state within the insertion hole 22 (see FIG. 5 ). The housing-side holding protrusions 108 contact the outer peripheral surface of the tubular connecting portion 94 from all sides. As a result, the tubular connecting portion 94 is not only held to the outer shell 13 by the press-fitting blades 118 and the holding protrusions 121, but also held to the housing 18 by the housing-side holding protrusions 108 located on the opposite side (front side) of the holding protrusions 121 across the press-fitting blades 118. Therefore, in the first embodiment, the axial center of the tubular connecting portion 94 can be more reliably prevented from shifting. As a result, the axial center of the tubular connecting portion 94 can be aligned with the axial center of the mating outer conductor 311 (see FIG. 2 ).

[0081] Next, the board-side shell body 14 is assembled to the shell body 13 from below (see FIG. 12). Toward the end of the assembly process of the board-side shell body 14, the protrusion 72 interferes with the side portion 38, causing the side portion 38 to elastically deform somewhat outward in the width direction, with the upper portion 37 acting as a fulcrum. When the assembly of the board-side shell body 14 is complete, the engaging protrusion 47 of the shell body 13 comes into contact with the bottom surface 92 of the groove portion 52 of the board-side shell body 14, stopping the assembly of the board-side shell body 14. A restoring force acts on the side portion 38, causing the protrusion 72 to fit into the recess 56 (see FIG. 9). Because a lap margin is provided between the protrusion 72 and the recess 56, the protrusion 72 can contact the inner surface of the recess 56 and maintain this contact. The fit between the recess 56 and the protrusion 72 can be seen from the rear.

[0082] Furthermore, when assembly of the board-side outer shell body 14 is complete, the press-fit protrusion 75 is fitted into the press-fit recess 45 from below, and each contact rib 68 of the press-fit protrusion 75 comes into compressed or crushed contact with the inner surface of the opening side of the press-fit recess 45. Therefore, the board-side outer shell body 14 is stably held in a state where it is restricted from tilting in the front-to-rear direction relative to the outer shell body 13.

[0083] Furthermore, when the assembly of the substrate-side outer shell body 14 is completed, the second connecting protrusion 76 is fitted into the fitting groove 34 of the housing 18 (see Figure 13), and the pressing rib 78 of the second connecting protrusion 76 comes into contact with the front surface of the second locking protrusion 32, so that the second connecting protrusion 76 is held in a non-detachable state relative to the housing 18.

[0084] Furthermore, when the assembly of the board-side shell body 14 is complete, the back portion 61, the rising portion 62, and the partition portion 63 are fitted into the fitting receiving portion 39 of the shell body 13, and the engaging protrusions 49 of the board-side shell body 14 are fitted into the grooves 51 of the shell body 13 (see FIG. 9), and the engaging protrusions 47 of the shell body 13 are fitted into the grooves 52 of the board-side shell body 14. The contact ribs 65-68 of the board-side shell body 14 come into compressed or crushed contact with corresponding surfaces, such as the inner surfaces of the grooves 51 of the shell body 13 and the outer surfaces of the engaging protrusions 47. As a result, multiple electrical connection structures (contact structures) are formed between the shell body 13 and the board-side shell body 14 via the contact ribs 65-68. This improves the reliability of the electrical connection between the shell body 13 and the board-side shell body 14.

[0085] Each of the contact ribs 65-68 contacts the corresponding surface of the outer shell body 13 in the vertical direction. Therefore, even if a vertical vibration force is applied to the outer shell body 13 and the board-side shell body 14, the contact state of each of the contact ribs 65-68 can be maintained. In particular, in the case of the first embodiment, each of the contact ribs 65-68 is formed in large numbers on the inner surface of each groove 52 of the board-side shell body 14 and on the outer surface of each engaging protrusion 49, and each engaging protrusion 49 of the board-side shell body 14 is fitted into each groove 51 of the outer shell body 13, and the engaging protrusion 47 of the outer shell body 13 is fitted into the groove 52 of the board-side shell body 14, so that each of the contact ribs 65-68 can reliably contact the corresponding surface of the outer shell body 13.

[0086] When the outer shell 13 and the board-side outer shell 14 are assembled, as shown in Figure 2, the rising portion 62 is positioned so as to cover from behind the outer conductor tube 15, short dielectric 16, and short inner conductor 12 arranged in the lower through-hole 46. The back portion 61 is positioned so as to cover from behind the outer conductor tube 15, long dielectric 17, and long inner conductor 11 arranged in the upper through-hole 46. The lead-out portions 102 of the inner conductors 11, 12 are surrounded on all sides by the outer conductors 13, 14, and 15, except for the board connection portion 107. This completes the assembly of the shielded connector 10.

[0087] Next, the shielded connector 10 is installed on the surface of the circuit board 200 (see FIGS. 2 and 8 to 10). The board connection portions 107 of each of the inner conductors 11 and 12 are inserted into the connection holes 202 of the circuit board 200, each of the leg portions 54 of the outer shell 13 is inserted into the fixing holes 201 of the circuit board 200, and each of the mounting portions 84 to 87 is placed on the lands of the conductive portions of the circuit board 200. In this state, reflow soldering is performed, whereby the board connection portions 107 of each of the inner conductors 11 and 12 are solder-connected to the conductive portions for signals in the connection holes 202 of the circuit board 200. Furthermore, each of the leg portions 54 is solder-fixed to the fixing holes 201, and each of the mounting portions 84 to 87 is solder-connected to the conductive portions for grounding.

[0088] Each inner conductor 11, 12 is surrounded by a plurality of mounting portions 84-87 on the bottom surface 92 of the board-side outer shell 14. This suppresses crosstalk between adjacent inner conductors 11, 12 in the width direction and the front-to-rear direction. Furthermore, the board-side outer shell 14 is formed with a recessed recess 88 that is recessed away from the surface wiring of the circuit board 200, which prevents the board-side outer shell 14 from being electromagnetically coupled to the surface wiring.

[0089] When reflow soldering is performed, the reflow heat is transferred from the outer surface of the board-side shell body 14 to the mounting portions 84-87, melting the solder (paste solder) corresponding to the mounting portions 84-87. In the case of the first embodiment, the board-side shell body 14 has a recessed portion 91 extending from the back surface 93 of the back portion 61 to the bottom surface 92, and the thickness of the partition portion 63 is reduced, thereby reducing the thermal conduction resistance and improving the heat transfer to the mounting portions 84-87. In particular, the recessed portion 91 extends to the vicinity of the side mounting portion 85 on the bottom surface 92 of the board-side shell body 14, effectively preventing the side mounting portion 85 from becoming unsoldered.

[0090] Furthermore, in this embodiment 1, as shown in FIG. 10, the solder joint state of the side mounting portion 85 to the conductive portion of the circuit board 200 (see the solder fillet indicated by symbol b in FIG. 10) can be confirmed through the opening on the back surface 93 of the recessed portion 91.

[0091] [Another embodiment of the present disclosure] The first embodiment disclosed herein should be considered to be illustrative in all respects and not restrictive. In the first embodiment, the outer shell is configured as a separate body from the substrate-side outer shell. However, in other embodiments, the outer shell may be formed integrally with the substrate-side outer shell. In the first embodiment, the protruding portion of the outer conductor tube has a contact protrusion. However, in other embodiments, the protruding portion does not have to have a contact protrusion. In this case, the side surface (plate surface) of the protruding portion can be brought into contact with the restricting portion of the outer shell. In the first embodiment, the housing has a housing-side holding protrusion. However, in other embodiments, the housing does not necessarily have to have a housing-side holding protrusion. In this case, it is preferable to form a holding protrusion corresponding to the housing-side holding protrusion on the outer peripheral surface of the outer conductor tube. [Explanation of symbols]
