Description

Technical Field

[0001] This disclosure relates to a shielded connector. Background Technology

[0002] The prior art shielded connector includes: a housing that holds terminals disposed at the ends of wiring components (wires); a cover component that covers the working opening of the housing; a shielding component that covers the outside of the housing with a first cover and a second cover and electromagnetically shields the outside of the cover component, the first cover and the second cover being configured to face each other when the outside of the housing is sandwiched along the thickness direction; and an electromagnetic shielding cover component that covers and electromagnetically shields the outside of the cover component (see, for example, patent document JP2019-110042A).

[0003] The housing includes: a tubular portion through which a wiring component is inserted; and a terminal holding portion that holds a terminal such that its intersecting direction with the wiring component is a mating direction, and the housing is configured to be approximately L-shaped. When a terminal is connected to the end of the wiring component, the terminal whose intersecting direction with the wiring component is a mating direction cannot be inserted through the tubular portion. Therefore, a working opening is formed on the rear surface side of the terminal holding portion for connecting a terminal to the end of the wiring component that is inserted through the tubular portion and pulled into the terminal holding portion.

[0004] The shielded connector includes a press-fit structure. Therefore, when assembling the shielded connector, the press-fit protrusion in the first cover can be press-fitted into the press-fit recess in the housing, and the end portion of the press-fit protrusion can be accommodated in the receiving recess in the second cover. That is, with the relative positions of the housing and the first cover fixed, the shielded connector positions the relative positions of the first and second covers. With the first and second covers accommodating the housing within the receiving space, the shielded connector is assembled by being fastened to the connected object together with the electromagnetic shielding cover component by a fastening member.

[0005] In a shielded connector including a press-fit structure, when the receiving recess of the second cover is received within the press-fit protrusion of the first cover pressed into the press-fit recess of the housing, the receiving recess needs to be aligned with the end of the press-fit protrusion protruding from the press-fit recess. However, when the shielded connector is assembled to a connected object, if an attempt is made to receive the receiving recess of the second cover within the press-fit protrusion of the first cover from the fastening direction of the fastening member (rear surface side of the housing), the receiving portion is difficult to see, resulting in poor operability. The shielded connector has a structure in which the first and second covers, as shielding components, are fastened together to the connected object by fastening members with the housing received in the receiving space. Therefore, the shielded connector cannot be assembled by integrally fixing the shielding component, housing, and electromagnetic shielding cover component before assembly to the connected object, resulting in poor handleability. Summary of the Invention

[0006] An exemplary aspect of this disclosure provides a shielded connector that is easy to handle and improves assembly operability.

[0007] According to an exemplary aspect of the subject matter of this disclosure, a shielded connector includes: a housing having a front opening and a wire insertion portion, the front opening being configured to be covered by an inner housing having a connector mating portion formed therein, the wire insertion portion having a tubular shape and opening in a second direction intersecting the opening direction of the front opening, i.e., a first direction; a terminal configured to be received in a terminal receiving portion of the housing and having an end portion configured to connect to the mating terminal; a connecting terminal having an end configured to connect to the end of a wire; and a first shielding cover configured to cover the housing and the portion disposed of the wire. A rear surface opposite to the front surface of the front opening; a second shield having a braided connection and a cover fixing portion for covering the braided connection of the wire extending from the wire insertion portion, and the cover fixing portion being configured to be electrically connected to the first shield; a first fastening member configured to secure the housing to the first shield; a second fastening member configured to fasten the other end of the connecting terminal to a terminal holder received in the terminal receiving portion of the housing; and a third fastening member configured to fasten the cover fixing portion of the second shield to the first shield. The fastening directions of the first, second, and third fastening members are parallel to each other and fasten from the front surface side of the housing.

[0021] In the following description, examples of embodiments of the subject matter will be described with reference to the accompanying drawings. Figure 1 This is a perspective view of a shielded connector 1 according to an embodiment of the subject matter of this disclosure. Figure 2 yes Figure 1 An exploded perspective view of shielded connector 1 is shown.

[0022] The shielded connector 1 in this embodiment is a shielded connector used, for example, in the power circuit of an inverter or engine in a vehicle such as a hybrid vehicle or electric vehicle. The shielded connector 1 mates with and connects to a mating connector disposed within the metal housing of the connection object, such as an inverter or engine. Figure 1 and Figure 2As shown, the shielded connector 1 according to this embodiment includes an upper shield 10 as a first shield, a housing 20, two busbars 31 and 41 as terminals, two wires 50 equipped with terminals, two wire shielding components 80, and first to third fastening components 3, 5 and 7.

[0023] The housing 20 has: in the mating direction (first direction) X (see mating connector (not shown) with the mating connector) X (see mating connector (not shown)). Figure 2 The housing 20 has a front opening 28 that opens forward; and a tubular wire insertion portion 26 that opens in a direction intersecting the front opening 28 (a second direction). An inner housing 90, having a connector mating portion 92 that mates with a mating connector, is assembled to the front opening 28. The housing 20 and the inner housing 90 are formed of a synthetic resin having electrical insulating properties. When the inner housing 90 is assembled, the front opening 28 of the housing 20 is covered by the inner housing 90.

[0024] like Figure 2 As shown, the housing 20 has two terminal receiving portions 21 and 22 and two wire insertion portions 26 and 26. The two terminal receiving portions 21 and 22 are exposed on the front side of the mating direction X through the front opening 28. The two wire insertion portions 26 and 26 are respectively connected to the terminal receiving portions 21 and 22 and open in a direction that intersects with the front opening 28.

[0025] like Figure 4 As shown, the terminal receiving portion 21 is an L-shaped recess of the mounting portion 32 that accommodates the busbar 31, and is surrounded by a peripheral wall 21a. The peripheral wall 21a positions the busbar 31 by correspondingly fitting the L-shaped shape of the mounting portion 32. However, the peripheral wall 21a is positioned in the direction of the opening of the wire insertion portion 26 along the mounting portion 32. Figure 4 There is a predetermined gap between the end edge of the peripheral wall 21a and the mounting portion 32 in the direction perpendicular to the opening direction of the wire insertion portion 26. Figure 4 There is almost no gap between the ends of the busbar 31 (in the horizontal direction). Therefore, the busbar 31 is positioned relative to the opening direction of the wire insertion part 26, and the busbar 31 can be moved with the aforementioned gap in a direction perpendicular to the opening direction of the wire insertion part 26.

[0026] The nut 25, which engages with the second fastening member 5, is press-fitted and secured to the bottom of the terminal receiving portion 21. A recess 21b, designed to prevent interference with the positioning pin 108 of the terminal positioning fixture 105 (described later), is formed in the bottom of the terminal receiving portion 21 on the opposite side of the wire insertion portion 26, across the nut 25.

[0027] The terminal receiving portion 22 is a rectangular recess that accommodates the mounting portion 42 of the busbar 41 and is surrounded by a peripheral wall 22a. The peripheral wall 22a positions the busbar 41 by correspondingly fitting the rectangular shape of the mounting portion 42 of the busbar 41. However, the peripheral wall 22a has a predetermined gap between itself and the end edge of the mounting portion 42 along the opening direction of the wire insertion portion 26, but there is almost no gap between itself and the end edge of the mounting portion 42 along the direction perpendicular to the opening direction of the wire insertion portion 26. Therefore, the busbar 41 is positioned relative to the opening direction of the wire insertion portion 26, but the busbar 41 can be displaced with the aforementioned gap in the direction perpendicular to the opening direction of the wire insertion portion 26.

[0028] The nut 25, which engages with the second fastening member 5, is press-fitted and secured to the bottom of the terminal receiving portion 22. A recess 22b, designed to avoid interference with the positioning pin 108 of the terminal positioning fixture 105 (described later), is formed in the bottom of the terminal receiving portion 22 on the opposite side of the wire insertion portion 26, across the nut 25.

[0029] In the housing 20, a tubular metal collar 27 is embedded in the gap between the two wire insertion portions 26 and 26 and in the outer end portions on opposite sides of the wire insertion portions 26 and 26. A first fastening member 3 passes through the collar 27 along the mating direction X. Two positioning holes 23 and 23 are provided at predetermined intervals on the outer periphery of the housing 20, and a plurality of locking claws 29 are formed on the outer surface of the peripheral wall defining the front opening 28.

[0030] like Figure 2 As shown, the inner housing 90 is formed in the shape of a plate, which has a shape corresponding to the front opening 28 of the housing 20, and is assembled from the front surface side to cover the front opening 28 of the housing 20. Therefore, the front opening 28 of the housing 20 is closed by the inner housing 90.

[0031] Multiple locking elements 93 with locking holes 94 are formed on the periphery of the inner housing 90. By assembling the inner housing 90 to the housing 20, locking claws 29 formed on the housing 20 are inserted into the locking holes 94 of the locking elements 93. Thus, the locking elements 93 are locked by the locking claws 29, and the inner housing 90 is held in the assembled state to the housing 20.

[0032] The inner housing 90 has a connector mating portion 92 that mates with a mating connector. The connector mating portion 92 is formed into an elongated tubular shape protruding along the mating direction X. Terminal insertion ports 91 and 91 for inserting the end portions of busbars 31 and 41 are formed at the front of the connector mating portion 92. In addition, a seal 95 is assembled to the outer periphery of the connector mating portion 92.

[0033] The upper shield 10 is a shielding component that covers the rear surface and outer peripheral surface of the electromagnetic shielding housing 20 on the side opposite to the front opening 28. The upper shield 10 is formed of a conductive metallic material. The upper shield 10 defines a receiving space 11 for accommodating the housing 20.

[0034] Positioning protrusions 15 and 15, corresponding to positioning holes 23 and 23 of housing 20, are provided on the bottom surface of upper shield 10. Positioning protrusions 15 and 15 can engage with positioning holes 23 and 23 to position housing 20 when housing 20 is assembled to upper shield 10. That is, a positioning mechanism for positioning housing 20 relative to upper shield 10 is provided between the rear surface of upper shield 10 and housing 20.

[0035] Furthermore, the upper shielding cover 10 has two screw holes 12, into which the first fastening member 3 is screwed, and the first fastening member 3 is inserted through the tubular collar 27 of the housing 20. Near the upper shielding cover 10, which is used to insert the wires 26 and the lead-out groove 17 of the housing 20, three screw holes 14 are formed, into which the third fastening members 7 for fastening the two wire shielding members 80 are respectively screwed.

[0036] The busbar 31 includes an L-shaped mounting portion 32 and an end portion 33. The L-shaped mounting portion 32 is disposed in the terminal receiving portion 21 of the housing 20, and the end portion 33 is vertically disposed from one end of the mounting portion 32 and protrudes from the connector mating portion 92 of the inner housing 90 along the mating direction X. For example, the busbar 31 is formed of a conductive metal material such as copper, copper alloy, aluminum, or aluminum alloy. The other end of the mounting portion 32 is formed with a mounting hole 34 and a pair of terminal positioning holes 35. The second fastening member 5 is inserted through the mounting hole 34, and a pair of positioning pins 108 of the terminal positioning fixture 105 are inserted into the pair of terminal positioning holes 35.

[0037] The busbar 41 includes a rectangular mounting portion 42 and an end portion 33. The rectangular mounting portion 42 is disposed in the terminal receiving portion 22 of the housing 20, and the end portion 43 is disposed perpendicularly from one end of the mounting portion 42 and protrudes from the connector mating portion 92 of the inner housing 90 along the mating direction X. For example, the busbar 41 is formed of a conductive metal material such as copper, copper alloy, aluminum, or aluminum alloy. The mounting portion 42 is formed with a mounting hole 44 and a terminal positioning hole 45. The second fastening member 5 is inserted through the mounting hole 44, and a pair of positioning pins 108 of the terminal positioning fixture 105 are inserted into a pair of terminal positioning holes 45.

[0038] The wire 50 equipped with terminals includes a wire 51 and a connecting terminal 55 connected to the end of the wire 51. For example, the connecting terminal 55 is formed of a conductive metal material such as copper, copper alloy, aluminum, or aluminum alloy. One end of the connecting terminal 55 is a crimp portion that connects to the end of the wire 51, and the other end of the connecting terminal 55 is a flat electrical connection portion that is fastened to the mounting portion 32 of the busbar 31 or the mounting portion 42 of the busbar 41. The connecting terminal 55 includes a mounting hole 56 and a pair of stepped portions 57 and 578. The mounting hole 56 is drilled into the flat electrical connection portion and the second fastening member 5 is inserted through the mounting hole 56. The pair of stepped portions 578 are formed at the end of the electrical connection portion and abut against the positioning pin 108 of the terminal positioning fixture 105 (see...). Figure 4 ).

[0039] Wire 51 is an insulated wire with its conductor covered by a sheath, and the conductor protrudes from the sheath at its ends. The wire crimping portion of the connecting terminal 55 is crimped to the conductor of wire 51. Therefore, wire 51 is electrically connected to connecting terminal 55.

[0040] In the terminal-equipped wires 50 assembled to the housing 20, the connecting terminal 55 connected to the end of the wire 51 is inserted into the housing 20 from the wire insertion portion 26. A waterproof component 60 is attached to each wire 51 of the terminal-equipped wires 50, and the gap between the wire 51 and the inner peripheral surface 26a of the wire insertion portion 26 is sealed by the waterproof component 60 (see...). Figure 10 A split-type rear retainer 75, which is attached to the open end of the wire insertion portion 26, prevents the waterproof component 60 from falling out or detaching from the wire insertion portion 26. The rear retainer 75 prevents the wire 51 from bending outside the waterproof component 60.

[0041] The wire shielding component 80 includes a lower shielding cover 81 and a braid 87. The lower shielding cover 81 serves as a second shielding cover electrically connected to the upper shielding cover 10, and the braid 87 covers the wire 51 extending from the wire insertion portion 26. The lower shielding cover 81 has a cover fixing portion 82 and a braid connecting portion 83 (see...). Figure 10 The cover fixing part 82 is fastened to the upper shielding cover 10 by the third fastening member 7, and one end of the braided fabric 87 is connected to the braided fabric connecting part 83. The lower shielding cover 81 is formed of conductive metal material. Mounting holes 84 for the third fastening member 7 to be inserted are formed at both ends of the cover fixing part 82. The open end of the braided fabric 87 through which the wire 51 passes is externally fitted to the tubular braided fabric connecting part 83, and is fixed and electrically connected to the tubular braided fabric connecting part 83 by the shielding ring 85.

[0042] The first fastening member 3 that secures the housing 20 to the upper shield 10 is, for example, a bolt. The second fastening member 5 that secures the other end (electrical connection portion) of the connecting terminal 55 to the mounting portion 32 of the busbar 31 or the mounting portion 42 of the busbar 41 is, for example, a screw. In addition, the third fastening member 7 that secures the cover fixing portion 82 of the lower shield 81 to the upper shield 10 is, for example, a bolt.

[0043] Next, refer to Figures 3 to 8 The assembly of the shielded connector 1 according to this embodiment is described. First, as... Figure 3 As shown, the upper shield 10 is disposed in the assembly fixture 100 from the rear surface side. The assembly fixture 100 has a retaining recess 101 corresponding to the shape of the upper shield 10, and holds the upper shield 10 disposed with the receiving space 11 facing upward.

[0044] The housing 20 is assembled into the receiving space 11 of the upper shield 10 provided in the assembly fixture 100. At this time, the housing 20 is positioned when it is assembled into the upper shield 10 by engaging the positioning protrusions 15 and 15 of the upper shield 10 with the positioning holes 23 and 23. Therefore, it is beneficial to position the housing 20 relative to the upper shield 10 and improves the operability of fastening the first fastening member 3.

[0045] The housing 20 is fastened to the upper shield 10 from the rear surface side by the first fastening member 3. The first fastening member 3 passes through the tubular collar 27 of the housing 20 and is screwed into the screw hole 12 of the upper shield 10, thereby fastening the housing 20 to the upper shield 10.

[0046] Next, as Figure 4 As shown, busbars 31 and 41 are respectively arranged in terminal receiving portions 21 and 22 through the front opening 28 of housing 20. Busbar 31 is positioned in terminal receiving portion 21 by assembling the mounting portion 32 so that it is surrounded by the peripheral wall 21a of terminal receiving portion 21. Busbar 41 is positioned in terminal receiving portion 22 by assembling the mounting portion 42 so that it is surrounded by the peripheral wall 22a of terminal receiving portion 22.

[0047] After that, as Figure 5 and Figure 6 As shown, the connecting terminal 55, which is connected to the end of the wire 51, is inserted into the housing 20 through the wire insertion portion 26. The electrical connection portion of the connecting terminal 55, which is inserted through the wire insertion portion 26 communicating with the terminal receiving portion 21, is fastened to the mounting portion 32 of the busbar 31. The electrical connection portion of the connecting terminal 55, which is inserted through the wire insertion portion 26 communicating with the terminal receiving portion 22, is fastened to the mounting portion 42 of the busbar 41.

[0048] Here, in order to secure the electrical connection portions of each connecting terminal 55 to the mounting portion 32 of the busbar 31 or the mounting portion 42 of the busbar 41, the wire 50 equipped with the terminal must be inserted into the housing 20 so that the mounting hole 56 of the connecting terminal 55 overlaps with the mounting hole 34 of the mounting portion 32 or the mounting hole 44 of the mounting portion 42. Therefore, when the wire 50 equipped with the terminal is inserted into the housing 20, the terminal positioning fixture 105 is used.

[0049] The terminal positioning fixture 105 includes a body 107 and a pair of positioning pins 108 protruding from the lower surface of the body 107. Each of the pair of positioning pins 108 has a length such that the side surface of each positioning pin 108 abuts against a pair of stepped portions 57 and 57 respectively formed at the end of the connecting terminal 55, and the end portion of each positioning pin 108 engages in the terminal positioning hole 35 of the busbar 31 or the terminal positioning hole 45 of the busbar 41. The pair of positioning pins 108 has a spacing capable of clamping a protrusion formed between the pair of stepped portions 57 and 57.

[0050] For example, when a wire 50 equipped with a terminal is inserted into the housing 20 such that the mounting hole 56 of the connecting terminal 55 overlaps with the mounting hole 34 of the mounting portion 32, the terminal positioning fixture 105 is pre-set on the mounting portion 32 of the busbar 31, such as Figure 6 As shown. At this time, in the terminal positioning fixture 105, the bottom surface of the main body 107 is placed on the mounting part 32, and the end part of the positioning pin 108 is engaged in the terminal positioning hole 35 of the busbar 31.

[0051] like Figure 7 As shown, when the wire 50 equipped with terminals is inserted into the housing 20, the stepped portion 57 of the connecting terminal 55 abuts against the side surface of the positioning pin 108, thereby restricting the insertion of the connecting terminal 55. When the stepped portion 57 of the connecting terminal 55 abuts against the side surface of the positioning pin 108, the terminal positioning hole 35 is opened in such a way that the mounting hole 56 of the connecting terminal 55 overlaps with the mounting hole 34 of the mounting portion 32. Therefore, by simply inserting the wire 50 equipped with terminals into the housing 20 until the stepped portion 57 of the connecting terminal 55 abuts against the side surface of the positioning pin 108, the mounting hole 56 of the connecting terminal 55 can overlap with the mounting hole 34 of the mounting portion 32.

[0052] Therefore, the second fastening member 5 is easily inserted through the mounting holes 56 and 34, and then screwed into the nut 25 that has been press-fitted and fastened to the bottom of the terminal receiving portion 21, so that the electrical connection portion of the connecting terminal 55 can be fastened to the mounting portion 32 of the busbar 31. Similarly, when the wire 50 equipped with the terminal is inserted into the housing 20, the terminal positioning jig 105 can be used to make the mounting hole 56 of the connecting terminal 55 overlap with the mounting hole 44 of the mounting portion 42.

[0053] Next, as Figure 8 As shown, the wire shielding component 80 is fastened to the vicinity of the lead-out slot 17 of the upper shielding cover 10 (see...). Figure 2 Specifically, the cover fixing part 82 of the lower shielding cover 81 is screwed into the screw hole 14 of the upper shielding cover 10 (see...). Figure 2 The third fastening member 7 is fastened to the cover fixing part 82, and the braid 87 for covering the wire 51 is connected to the braid connecting part 83.

[0054] The two lower shields 81 are fastened to the upper shield 10 adjacent to each other. Therefore, by overlapping the mounting holes 84 formed in the ends of the adjacent shield fixing parts 82 to fasten the third fastening member 7, the number of the third fastening members 7 can be reduced, and the lower shields 81 can be electrically connected to each other.

[0055] like Figure 2 and Figure 8 As shown, the first fastening component 3, the second fastening component 5, and the third fastening component 7 have fastening directions D1, D2, and D3 that are parallel to each other, and are fastened from the front surface side of the housing 20. Therefore, when assembling the shielded connector 1, the operator can fasten all the first fastening components 3, the second fastening components 5, and the third fastening components 7 from the same direction (from the front surface side of the housing 20), and can visually inspect the overall fastening status, thus improving assembly operability. Finally, as... Figure 1 As shown, the inner housing 90 covering the front opening 28 is attached to the housing 20, and the assembly of the shielded connector 1 is completed.

[0056] In the shielded connector 1 according to this embodiment, since the first shield, housing, terminal, connecting terminal and second shield are integrally fixed and assembled by the first to third fastening members, the processing (operability) until the shielded connector 1 is mated to the mating connector is good.

[0057] According to the shielding connector 1 of this embodiment, as follows: Figure 4 As shown, the busbar 31 arranged in the terminal receiving portion 21 of the housing 20 is oriented relative to the opening direction of the wire insertion portion 26. Figure 4 The busbar 31 is positioned in the vertical direction relative to the direction orthogonal to the opening direction of the wire insertion part 26. Figure 4The horizontal direction (in the middle) can be shifted with a gap. Therefore, when the other end of the connecting terminal 55 is fastened to the mounting portion 32 of the busbar 31 by the second fastening member 5, the assembly tolerance between the busbar 31 and the connecting terminal 55 can be absorbed, and the operability of fastening the second fastening member 5 can be improved. When the shielded connector 1 is mated to the mating connector, the mating tolerance of the busbar 31 relative to the mating terminal can also be absorbed, and the increase of the connector mating force can also be suppressed. This also applies to the busbar 41 arranged in the terminal receiving portion 22 of the housing 20.

[0058] Figure 9A and Figure 9B These are, respectively, a perspective view and a cross-sectional perspective view of a waterproof component 60 that seals the gap between the wire insertion part 26 and the wire 51 in a watertight manner. For example... Figure 9A and 9B As shown, the waterproof component 60 includes an annular rubber portion 61 and an annular resin portion 66. The rubber portion 61 has two internal sealing portions 65 and 65 and two external sealing portions 63 and 63. The two internal sealing portions 65 and 65 contact the outer peripheral surface of the wire 51 in a pressing manner, and the two external sealing portions 63 and 63 contact the inner peripheral surface (first inner peripheral surface) 26a of the wire insertion portion 26 in a pressing manner.

[0059] The resin portion 66 integrally comprises a plurality of abutment portions 67 and an outer ring portion 68. The plurality of abutment portions 67 abut against the outer peripheral surface of the wire 51, and the outer ring portion 68 abut against the inner peripheral surface (second inner peripheral surface) 26b of the narrowed portion (described later). The narrowed portion is provided on the inner peripheral surface 26a on the terminal receiving portion 21 (22) side in the wire insertion portion 26, and the resin portion 66 is embedded in the rubber portion 61. The abutment portions 67 and the outer ring portion 68 do not necessarily abut against the outer peripheral surface of the wire 51 and the inner peripheral surface 26b of the narrowed portion respectively, and can have a small gap. The four abutment portions 67 are arranged at equal intervals in the circumferential direction of the resin portion 66 and have a protrusion height lower than that of the inner sealing portion 65. The outer diameter of the outer ring portion 68 is smaller than the outer diameter of the outer sealing portion 63.

[0060] like Figure 10 As shown, the waterproof component 60 between the wire insertion part 26 and the wire 51 can seal the gap between the wire insertion part 26 and the wire 51 in a watertight manner through the rubber part 61. Furthermore, when tightening the second fastening component 5, when the shielded connector is mated with the mating connector, etc., it is tightened to a direction orthogonal to the opening direction of the wire insertion part 26. Figure 10 The connecting terminal 55 of the mounting part 32 (42) of the busbar 31 (41) which can be moved in the left and right direction can be moved in a direction orthogonal to the opening direction of the wire insertion part 26.

[0061] like Figure 11As shown, when the connecting terminal 55 is in a direction orthogonal to the opening direction of the wire insertion part 26 ( Figure 11 When the wire 51 shifts upwards (to the left) relative to the opening center axis Y of the wire insertion portion 26, a force that eccentrically offsets to the left acts on the wire 51 whose end is connected to the connection terminal 55. However, when the wire 51 is eccentrically offset to the left relative to the opening center axis Y, the eccentricity of the wire 51 relative to the opening center axis Y of the wire insertion portion 26 is limited by the resin portion 66 of the waterproof component 60, in which the opposing abutment portion 67 abuts against the outer peripheral surface of the wire 51 and the outer ring portion 68 abuts against the inner peripheral surface 26b of the narrowing portion. Therefore, by means of the rubber portion 61 of the waterproof component 60 having the inner sealing portion 65 and the outer sealing portion 63, the effect of the eccentricity (deviation) of the wire 51 can be reduced, and the decrease in sealing performance can be suppressed.

[0062] Figure 12 This is a perspective view of a shielded connector 1A according to another embodiment of the subject matter of this disclosure. In the shielded connector 1A, the same components as those in the shielded connector 1 according to the embodiment are indicated by the same reference numerals, and their detailed descriptions will be omitted. The shielded connector 1A is provided with a front shield 97 as a third shield, which covers the front surface side of the housing 20 except for the connector mating portion 92.

[0063] The front shield 97 is a shielding component that covers and electromagnetically shields the front surface of the inner housing 90, excluding the connector mating portion 92. The front shield 97 is formed of a conductive metal material. The locking member 98 locks to the locking portion 96 formed in the inner housing 90, the two locking members 99a are fastened together to the third fastening member 7, and the locking member 99b is fastened to the fastening member 9, thereby fixing the front shield 97 to the front surface of the inner housing 90.

[0064] According to the shielded connector 1A of this embodiment, when the shielded connector 1A is not assembled such that the front surface of the housing 20 faces the metal shell of the connected object (not shown), the shielding performance of the shielded connector 1A can be ensured by covering the front surface of the housing 20 with the front shield cover 97. In other words, when the shielded connector 1A is assembled such that the front surface of the housing 20 faces the metal shell of the connected object, the shielding performance can be ensured without covering the front surface of the housing 20 with the front shield cover 97.

[0065] Therefore, shielded connectors 1 and 1A according to the above embodiments can provide shielded connectors that are easy to handle and can improve assembly operability.

[0066] While the subject matter of this disclosure has been described with respect to specific exemplary embodiments thereof, the scope of the subject matter of this disclosure is not limited to the exemplary embodiments described above, and those skilled in the art will understand that various changes and modifications may be made therein without departing from the scope of the subject matter of this disclosure as defined by the appended claims.

[0067] According to one aspect of the above embodiments, the shielded connector (1, 1A) includes: a housing (20) having a front opening (28) and a wire insertion portion (26), the front opening (28) being configured to be covered by an inner housing (90), in which a connector mating portion (92) configured to mate with a mating connector is formed, the wire insertion portion (26) having a tubular shape and opening in a second direction intersecting the opening direction of the front opening (28), i.e., a first direction; terminals (e.g., busbars 31, 41) configured to be received in terminal receiving portions (21, 22) of the housing (20) and having an end portion configured to connect to a mating terminal; a connecting terminal (55) having one end configured to connect to the end of a wire (51); and a first shield (e.g., an upper shield 10) configured to cover the front opening of the housing (20). (28) The rear surface opposite to the front surface; the second shield (e.g., the lower shield 81) having a braided connecting portion (83) and a cover fixing portion (82) for covering the braid (87) of the wire (51) leading out from the wire insertion portion (26) connected to the braided connecting portion (83), and the cover fixing portion (82) is configured to be electrically connected to the first shield (upper shield 10); the first fastening member (3) configured to fix the housing (20) to the first shield (upper shield 10); the second fastening member (5) configured to fasten the other end of the connecting terminal (55) to the mounting portion (32, 42) of the terminal (busbar 31, 41) housed in the terminal receiving portion (21, 22) of the housing (20); and the third fastening member (7) configured to fasten the cover fixing portion (82) of the second shield (lower shield 81) to the first shield (upper shield 10). The fastening directions (D1, D2, D3) of the first fastening component (3), the second fastening component (5) and the third fastening component (5) are parallel to each other and are fastened from the front surface side of the housing (20).

[0068] When assembling the shielded connector described above, firstly, the housing is secured to the first shielding cover from the rear surface side using the first fastening member. Next, after arranging the terminals in the terminal receiving portion of the housing through the front opening, a connecting terminal, one end of which is connected to the end of the wire, is inserted into the housing through the wire insertion portion. The other end of the connecting terminal inserted into the housing is secured to the terminal mounting portion using the second fastening member. Next, the cover fixing portion of the second shielding cover is secured to the first shielding cover using the third fastening member, in which the braid for covering the wire is connected to the braid connection portion. The first to third fastening members have parallel fastening directions and are fastened from the front surface side of the housing. Finally, the inner housing covering the front opening is attached to the housing. Therefore, when assembling the shielded connector, the operator can secure all the first to third fastening members from the same direction (from the front surface side of the housing), and can visually inspect the overall fastening status, thus improving assembly operability. In a shielded connector with this configuration, since the first shield, housing, terminal, connecting terminal and second shield are integrally fixed and assembled by the first to third fastening components, the process (operability) until the shielded connector is mated to the mating connector is good.

[0069] A positioning mechanism (e.g., positioning protrusion 15 and positioning hole 23) may be provided between the first shield (upper shield 10) and the rear surface of the housing (20), the positioning mechanism being configured to position the housing (20) relative to the first shield (upper shield 10).

[0070] With this construction, a positioning mechanism, including positioning protrusions and positioning holes, is positioned between the rear surface of the first shield and the housing. This facilitates the positioning of the housing relative to the first shield and improves the operability of fastening the first fastening component.

[0071] The terminals (busbars 31, 41) housed in the terminal receiving portions (21, 22) of the housing (20) can be positioned relative to the second direction and can be displaced relative to a direction orthogonal to the second direction.

[0072] With this structure, the terminal arranged in the terminal receiving portion of the housing is positioned relative to the opening direction of the wire insertion portion, and can be displaced relative to the direction perpendicular to the opening direction of the wire insertion portion. Therefore, when the other end of the connecting terminal is fastened to the terminal mounting portion by the second fastening member, assembly tolerances between the terminal and the connecting terminal can be absorbed, and the operability of fastening the second fastening member can be improved. When the shielded connector is mated to the mating connector, mating tolerances between the terminal and the mating terminal can also be absorbed, and the increase in connector mating force can also be suppressed.

[0073] The shielded connector (1, 1A) may also include a waterproof component (60) configured to attach to the wire (51) and watertightly seal the gap between the wire insertion portion (26) and the wire (51). The waterproof component (60) may include: a rubber portion (61) having an inner sealing portion (65) and an outer sealing portion (63), the inner sealing portion (65) being configured to press against the outer peripheral surface of the wire (51), and the outer sealing portion (63) being configured to press against the first inner peripheral surface (26a) of the wire insertion portion (26); a resin portion (66) integrally having a plurality of abutting portions (67) being configured to abut against the outer peripheral surface of the wire (51); and an outer ring portion (68) being configured to abut against a second inner peripheral surface (26b) of a narrowing portion provided on the first inner peripheral surface (26a), the narrowing portion being provided on the first inner peripheral surface on the side of the wire insertion portion (26) connected to the terminal receiving portions (21, 22), the resin portion (66) being embedded in the rubber portion (61).

[0074] With this structure, the gap between the wire insertion part and the wire is sealed watertight by the rubber part of the waterproof component. Furthermore, when fastening the second fastening part, or when the shielded connector is mated to the mating connector, the connecting terminal of the mounting part, which is movable in a direction orthogonal to the opening direction of the wire insertion part, can be moved in the same direction. When the connecting terminal is moved in a direction orthogonal to the opening direction of the wire insertion part, an eccentric force relative to the central axis of the opening of the wire insertion part acts on the wire whose end is connected to the connecting terminal. However, when the wire is eccentric relative to the central axis of the opening of the wire insertion part, this eccentricity is limited by the resin part of the waterproof component, in which multiple abutting portions abut against the outer peripheral surface of the wire and an outer ring portion abuts against the inner peripheral surface of the narrowing portion. Therefore, by using the rubber part of the waterproof component, which has both an internal sealing portion and an external sealing portion, the effect of wire eccentricity (deviation) can be reduced, and a decrease in sealing performance can be suppressed.

[0075] The shielded connector (1A) may also include a third shield (e.g., a front shield 97) configured to cover the front surface of the housing (20) except for the connector mating portion (92).

[0076] With this configuration, when the shielded connector is not assembled such that the front surface of the housing faces the metal shell of the connected object, the shielding performance of the shielded connector can be ensured by covering the front surface of the housing with a third shield. In other words, when the shielded connector is assembled such that the front surface of the housing faces the metal shell of the connected object, shielding performance can be ensured without covering the front surface of the housing with a third shield.
