[0027] Figure 9 express Figure 8 Section IX-IX. Figure 10 express Figure 8 The X-X section. Figure 11 express Figure 10 The XI-XI section.

[0028] The shielded connector 1 of this embodiment is connected, for example, to equipment mounted on a vehicle such as an automobile. Figure 1 and Figure 2 As shown, the shielded connector 1 includes a housing 2, a sealing member 3, a retainer 4, and a cover 5. A wire 7 covered by a braided fabric 6 is connected to the shielded connector 1. The cover 5 is a cylindrical component made of conductive metal and is called a shielding cover. The ends of the braided fabric 6 are fixed to the outer circumferential surface of the cover 5 by annular fastening members or the like. The cover 5 is fixed to the housing of the device to which it is connected and is electrically connected to the housing. That is, the braided fabric 6 is grounded to the housing of the device via the cover 5.

[0029] The housing 2 is a cylindrical component that houses and retains the terminal connected to the end of the wire 7. The housing 2 is formed, for example, of an insulating synthetic resin. The wire 7 extends outward from the end of the housing 2. The sealing member 3 is an annular component that seals between the outer peripheral surface of the wire 7 and the inner wall surface of the housing 2. The sealing member 3 is formed, for example, of an elastic resin. The retainer 4 is a component connected to the housing 2 and supporting the sealing member 3. The retainer 4 is formed, for example, of an insulating synthetic resin. The illustrated retainer 4 is constructed by combining two support bodies 40.

[0030] The housing 2 and retainer 4 are respectively inserted into the cover 5 and engaged inside the cover 5. The housing 2 and retainer 4 have opposing walls W1 and W2 that face the end faces 50a and 50b of the cover 5, respectively. The first opposing wall W1 of the housing 2 faces the first end face 50a of the cover 5, and the second opposing wall W2 of the retainer 4 faces the second end face 50b of the cover 5. The housing 2 and retainer 4 clamp the cover 5 through the two opposing walls W1 and W2 and are fixed to the cover 5. In the shielding connector 1 of this embodiment, there is no need for a protrusion or recess to fix the housing 2 to the cover 5. Therefore, the shielding connector 1 of this embodiment can sufficiently ensure the contact area between the outer peripheral surface of the cover 5 and the braided fabric 6, thereby improving the stability of the shielding performance.

[0031] like Figure 3 and Figure 4 As shown, the housing 2 is formed as a flat, cylindrical shape extending in a straight line. In the following description, the axial direction of the housing 2 is referred to as "axial direction X", and the width direction of the housing 2 is referred to as "width direction Y". Wires 7 are led out from the housing 2 along the axial direction X. The housing 2 holds multiple wires 7 side by side in the width direction Y. The direction orthogonal to both the axial direction X and the width direction Y is referred to as "height direction Z".

[0032] The housing 2 has: a first fitting portion 21, a second fitting portion 22, a plurality of retaining portions 23, and a plurality of cylindrical portions 24. The first fitting portion 21 is located at one end of the housing 2 along the axial direction X. The plurality of cylindrical portions 24 are located at the other end of the housing 2 along the axial direction X. The second fitting portion 22 is located between the first fitting portion 21 and the cylindrical portions 24.

[0033] The first fitting portion 21 fits into an opening provided on the housing of the device. The first fitting portion 21 is cylindrical in shape with an elongated oval cross-section. The outer wall surface of the first fitting portion 21 has a groove 21a for mounting the first sealing member 8A. The retaining portion 23 is a portion for retaining the terminal 20. The retaining portion 23 is disposed inside the first fitting portion 21 and extends along the axial direction X. The housing 2 of this embodiment has three retaining portions 23 arranged in the width direction Y. The illustrated retaining portion 23 has a rectangular cylindrical shape.

[0034] The second fitting part 22 is the part that fits into the cover 5. The second fitting part 22 is cylindrical in shape with an elongated oval cross-section. The outer wall surface of the second fitting part 22 has a groove 22a for mounting the second sealing member 8B.

[0035] like Figure 3 and Figure 4As shown, the cylindrical portion 24 has a cylindrical shape and protrudes from the second fitting portion 22 in the axial direction X. The housing 2 of the present embodiment has three cylindrical portions 24 arranged in the width direction Y. Each cylindrical portion 24 accommodates one sealing member 3. Each cylindrical portion 24 has two engaging pieces 25. The engaging piece 25 is a piece portion provided at the front end of the cylindrical portion 24 and has an engaging hole 25a. The cylindrical portion 24 has a slit 26 formed between the engaging piece 25 and the other portion of the cylindrical portion 24. The slit 26 is provided at both sides in the circumferential direction with respect to the engaging piece 25 and extends in the axial direction X.

[0036] The two engaging pieces 25 are symmetrically arranged with respect to the center axis CL of the cylindrical portion 24. In other words, the phases of the two engaging pieces 25 are shifted by 180°. The two engaging pieces 25 face each other in the height direction Z. The shape of the engaging piece 25 when viewed in the height direction Z is substantially rectangular. The engaging hole 25a penetrates the engaging piece 25 in the plate thickness direction of the engaging piece 25.

[0037] The housing 2 has a connecting wall 27 that connects two adjacent cylindrical portions 24 in the width direction Y. The connecting wall 27 connects the outer peripheral surface of the cylindrical portion 24 and the outer peripheral surface of the other cylindrical portion 24 adjacent thereto. As shown, Figure 3 The connecting wall 27 has a locking wall 27a that extends in the height direction Z. The locking wall 27a is located at the end portion of the connecting wall 27 on the second fitting portion 22 side. As shown, Figure 4 The connecting wall 27 is formed on both sides in the height direction Z with respect to the center axis CL. The connecting wall 27 forms a hollow portion 27b. The hollow portion 27b is surrounded by the connecting wall 27 and the outer peripheral surface of the cylindrical portion 24.

[0038] In the housing 2, the engaging piece 25 and the connecting wall 27 are provided as the first engaging portion Lk1 with which the retainer 4 is engaged.

[0039] The housing 2 has a first opposing wall W1. The first opposing wall W1 is a wall portion that opposes the first end surface 50a of the cover 5 in the axial direction X and is locked by the first end surface 50a. The first opposing wall W1 is a rib provided between the first fitting portion 21 and the second fitting portion 22. The first opposing wall W1 protrudes from the outer peripheral surface of the housing 2 toward a direction orthogonal to the axial direction X. The first opposing wall W1 extends along the entire circumference in the circumferential direction. The first opposing wall W1 is formed with the groove 21a and has a plurality of cutouts 28. The piece portion 8c of the first sealing member 8A is inserted into the cutout 28.

[0040] As shown, Figure 2 The retainer 4 of the present embodiment has two support bodies 40 of the same shape. By combining the two support bodies 40, a plug wall that plugs the second insertion port 55 of the cover 5 is formed in an oblong shape. As shown, Figure 5As shown, the support body 40 has a flat plate-shaped main body 43, a first engaging piece 41, a second engaging piece 42, a support wall 44, and a column 45. The main body 43 is a plug wall that plugs the second insertion port of the cover 5. The shape of the main body 43 when viewed from the axial direction X is a half-ellipse. The main body 43 has a straight line-shaped abutment surface 43a along the width direction Y. Two support bodies 40 are connected to the case 2 in a state where the abutment surfaces 43a abut against each other.

[0041] The main body 43 has a second opposite wall W2. The second opposite wall W2 is a portion that opposes the second end surface 50b of the cover 5 and is stopped by the second end surface 50b. The second opposite wall W2 is a rim portion of the main body 43 and extends in a manner of surrounding the first engaging piece 41, the second engaging piece 42, and the support wall 44.

[0042] The first engaging piece 41, the second engaging piece 42, the support wall 44, and the column 45 protrude from the main body 43 in the axial direction X. The support wall 44 is a portion that is inserted into the cylindrical portion 24 and supports the sealing member 3. The support wall 44 has a half-cylindrical shape. The support body 40 has three support walls 44 arranged in the width direction Y. A groove 44a in the axial direction X is provided to the outer peripheral surface of the support wall 44.

[0043] The first engaging piece 41 is disposed between the two support walls 44 adjacent to each other. The first engaging piece 41 engages with the connecting wall 27 of the case 2. The first engaging piece 41 has an arm shape and has flexibility. The support body 40 has two first engaging pieces 41 arranged in the width direction Y. The leading end of the first engaging piece 41 has a protruding portion 41a that protrudes toward the abutment surface 43a side.

[0044] The column 45 is disposed between the two support walls 44 adjacent to each other. The column 45 opposes the first engaging piece 41 in the height direction Z. More specifically, the column 45 opposes the surface of the first engaging piece 41 having the protruding portion 41a. The protruding length of the column 45 is shorter than the protruding length of the first engaging piece 41.

[0045] The second engaging piece 42 is disposed in the groove 44a. The second engaging piece 42 engages with the engaging piece 25 of the case 2. The second engaging piece 42 has an arm shape and has flexibility. The support body 40 has three second engaging pieces 42 arranged in the width direction Y. The leading end of the second engaging piece 42 has a protruding portion 42a that protrudes toward the opposite side to the abutment surface 43a side.

[0046] In the retainer 4, the first engaging piece 41 and the second engaging piece 42 are provided as the second engaging portion Lk2 that engages with the case 2.

[0047] As Figure 2As shown, the cover 5 has a cylindrical body 50 and a fixing part 51. The body 50 is oblong in shape in a cross-section orthogonal to the axial direction X. The fixing part 51 protrudes from the outer wall surface of the body 50 toward the height direction Z. The fixing part 51 has a through hole 51a through which the connecting member 53 can be inserted.

[0048] like Figure 2 and Figure 6 As shown, the cover 5 has: a first insertion port 54, a first end face 50a, a second insertion port 55, and a second end face 50b. The first insertion port 54 is an opening for inserting the housing 2. The second insertion port 55 is an opening for inserting the retainer 4. The first insertion port 54 is located at one end of the main body 50 along the axial direction X and opens towards the axial direction X. The second insertion port 55 is located at the other end of the main body 50 along the axial direction X and opens towards the axial direction X.

[0049] The first end face 50a is the end face that surrounds the first insertion port 54. The first end face 50a is a plane facing the axial direction X and has an elongated oval shape. The second end face 50b is the end face that surrounds the second insertion port 55. The second end face 50b is a plane facing the axial direction X and has an elongated oval shape. The first end face 50a and the second end face 50b face opposite directions to each other.

[0050] like Figure 7 As shown, the housing 2 and retainer 4 are inserted into the cover 5. The housing 2 is inserted into the cover 5 along the axial direction X from the first insertion port 54. The cylindrical portion 24 of the housing 2 is housed in the internal space of the cover 5, and the second fitting portion 22 fits into the cover 5. The housing 2 is inserted into the cover 5 until the first opposing wall W1 is opposite to the first end face 50a. Although Figure 7 It is not shown in the diagram, but wire 7 is plugged into cover 5.

[0051] The retainer 4 is inserted into the cover 5 along the axial direction X through the second insertion port 55. That is, the insertion direction In1 of the housing 2 relative to the cover 5 is opposite to the insertion direction In2 of the retainer 4 relative to the cover 5. The first engaging tab 41, the second engaging tab 42, and the support wall 44 of the retainer 4 are inserted into the internal space of the cover 5. The first engaging tab 41 engages with the connecting wall 27 of the housing 2 inside the cover 5. The second engaging tab 42 engages with the engaging tab 25 of the housing 2 inside the cover 5. The housing 2 and the retainer 4 are connected to each other and the cover 5 is held by the first opposing wall W1 and the second opposing wall W2. Thus, the assembly of the housing 2, the retainer 4, and the cover 5 is completed.

[0052] like Figure 8As shown, the shielded connector 1 is mounted on a wall portion 101 of a housing 100 of an apparatus. The first fitting portion 21 of the housing 2 is inserted into and fitted with an opening portion of the wall portion 101. The first sealing member 8A seals between the opening portion and the housing 2. The cover 5 is fixed to the wall portion 101 by a coupling member 53. The coupling member 53 is, for example, a bolt inserted into a through-hole 51a of the cover 5. In this case, a nut is screwed with the coupling member 53 inserted into the wall portion 101. The holding portion 23 of the housing 2 is connected to, for example, a connector of the apparatus. The terminal 20 is connected to a terminal of a counterpart connector.

[0053] As shown, the second engaging piece 42 of the retainer 4 is engaged with the engaging piece 25 of the housing 2 from the inside. The protrusion 42a of the second engaging piece 42 enters the engaging hole 25a and is stopped by the engaging piece 25. The terminal 20 is housed in the holding portion 23 of the housing 2 and is held by the holding portion 23. The electric wire 7 connected to the terminal 20 is led to the outside through the sealing member 3 and the retainer 4. Figure 9

[0054] The braid 6 is fixed to the outer peripheral surface of the main body 50 of the cover 5 and is electrically connected to the cover 5. The cover 5 of the present embodiment can stabilize the contact area of the outer peripheral surface of the main body 50 with the braid 6. As a comparative example, a cover provided with a protrusion, a through-hole, or a notch for engaging with the housing 2 or the retainer 4 in the contact area with the braid 6 is studied. In the cover of the comparative example, the contact area of the cover with the braid 6 is likely to deviate due to the presence of the protrusion, the through-hole, or the notch. In the shielded connector 1 of the present embodiment, it is not necessary to provide such a protrusion, a through-hole, or a notch on the cover 5. Therefore, the shielded connector 1 of the present embodiment can stabilize the contact area of the cover 5 with the braid 6.

[0055] Figure 10 As shown, the first engaging piece 41 of the retainer 4 is engaged with the connecting wall 27 of the housing 2 from the outside. The protrusion 41a of the first engaging piece 41 is stopped by the stop wall 27a of the connecting wall 27. The stop wall 27a is a surface intersecting the axial direction X and extending in the height direction Z. The stop wall 27a is opposite to the second fitting portion 22 in the axial direction X.

[0056] As shown, the first engaging piece 41 is inserted into the space S1 between the two adjacent cylindrical portions 24. The engaging structure is configured by effectively using the valley portion formed by the two cylindrical portions 24 of the circular cylindrical shape, thereby achieving the miniaturization of the shielded connector 1. Figure 11 Figure 10 As shown, the column 45 of the retainer 4 is inserted into the hollow portion 27b of the housing 2. The retainer 4 sandwiches the connecting wall 27 by the first engaging piece 41 and the column 45. Figure 11

[0057] ​​​In a state where the housing 2 is joined to the retainer 4, the first opposing wall W1 of the housing 2 opposes the first end surface 50a of the cover 5. In a case where the retainer 4 relatively moves in the pulling-out direction X2 with respect to the cover 5, the first opposing wall W1 abuts against the first end surface 50a. The first end surface 50a stops the first opposing wall W1 and restricts the retainer 4 from falling off. In addition, the second fitting portion 22 of the housing 2 can also be pressed into the cover 5. The cover 5 can also have a stop portion that stops the second fitting portion 22. These structures can more reliably restrict the movement of the housing 2 in the pulling-out direction X2 of the retainer 4.

[0058] In a state where the housing 2 is joined to the retainer 4, the second opposing wall W2 of the retainer 4 opposes the second end surface 50b of the cover 5. In a case where the housing 2 relatively moves in the pulling-out direction X1 with respect to the cover 5, the second opposing wall W2 abuts against the second end surface 50b. The second end surface 50b stops the second opposing wall W2 and restricts the housing 2 from falling off.

[0059] The retainer 4 of the present embodiment causes the first engaging piece 41 to engage from the outside with respect to the housing 2, and causes the second engaging piece 42 to engage from the inside with respect to the housing 2. With such a firm joining structure, even if an external force acts, the joining of the housing 2 and the retainer 4 is not easily released.

[0060] As described above, the shield connector 1 of the present embodiment has a cylindrical housing 2, a ring-shaped sealing member 3, a retainer 4 that supports the sealing member 3, a conductive cylindrical cover 5, and a braid 6 fixed to an outer peripheral surface of the cover 5. The housing 2 has a first engaging portion Lk1 and a first opposing wall W1, and houses and holds terminals 20. The sealing member 3 seals between an outer peripheral surface of an electric wire 7 connected to the terminals 20 and an inner wall surface of the housing 2. The retainer 4 has a second engaging portion Lk2 that engages with the first engaging portion Lk1 and a second opposing wall W2.

[0061] The cover 5 has a first insertion opening 54 into which the housing 2 is inserted, a first end surface 50a that surrounds the first insertion opening 54, a second insertion opening 55 into which the retainer 4 is inserted, and a second end surface 50b that surrounds the second insertion opening 55. The housing 2 and the retainer 4 are joined to each other by causing the first engaging portion Lk1 and the second engaging portion Lk2 to engage with each other inside the cover 5, causing the first opposing wall W1 to oppose the first end surface 50a, and causing the second opposing wall W2 to oppose the second end surface 50b.

[0062] In the shield connector 1 of the present embodiment, it is not necessary to provide a concave-convex for engagement in a contact region of the cover 5 with the braid 6. Therefore, the shield connector 1 of the present embodiment can stabilize the contact area of the cover 5 with the braid 6. In addition, it is possible to achieve the miniaturization of the cover 5 while securing the contact area of the cover 5 with the braid 6. In addition, the expansion of the number of poles in the shield connector 1 is easy.

[0063] The housing 2 of the present embodiment has a plurality of cylinder portions 24 arranged in the width direction Y, and houses the seal member 3 in the cylinder portions 24. The first engaging portion Lk1 of the housing 2 has a connection wall 27 connecting two adjacent cylinder portions 24 in the width direction Y. The second engaging portion Lk2 of the retainer 4 has the first engaging piece 41. The first engaging piece 41 is inserted into a space between the two adjacent cylinder portions 24 in the axial direction X and engages with the connection wall 27. By providing the engaging structure in the space between the two cylinder portions 24, miniaturization of the shield connector 1 can be achieved.

[0064] The first engaging portion Lk1 of the present embodiment has an engaging hole 25a formed in the cylinder portion 24. The second engaging portion Lk2 has a second engaging piece 42 inserted into the cylinder portion 24 and engaged with the engaging hole 25a. By engaging the retainer 4 with the housing 2 using the first engaging piece 41 and the second engaging piece 42, a lock structure that is not easily released is achieved.

[0065] The retainer 4 of the present embodiment has a plate-shaped main body 43. The main body 43 is a plug wall that plugs the second insertion port 55. The second opposing wall W2 is an outer edge portion of the main body 43 that is the plug wall. With this structure, the retainer 4 can be simplified.

[0066] In addition, the structure of the first engaging portion Lk1 and the second engaging portion Lk2 is not limited to the illustrated structure. The first engaging portion Lk1 and the second engaging portion Lk2 can have any structure that links the housing 2 and the retainer 4. The number of terminals 20 that the shield connector 1 has can be two or less, or four or more.

[0067] The shapes of the first opposing wall W1 and the second opposing wall W2 are not limited to the illustrated shapes. For example, the second opposing wall W2 can also be divided into a plurality. For example, the first opposing wall W1 can also be formed in a continuous ring shape without the cutout 28.

[0068] The retainer 4 can also not be divided into two support bodies 40. That is, the retainer 4 can also be integrally molded in a shape that combines the two support bodies 40.

[0069] The contents disclosed in the above-described embodiments can be appropriately combined to be executed.
