[Modes for carrying out the invention]

[0011] Hereinafter, examples of embodiments according to the present invention will be described with reference to the drawings. (Embodiment) Figures 1 and 2 are perspective and exploded perspective views of a shield connector 1 according to one embodiment of the present invention. In this specification, the front-back direction, up-down direction, and left-right direction of the shield connector 1 shall follow the directions of the arrows shown in FIGS. 1 to 3. That is, the front-back direction is the direction along the connector fitting direction of the shield connector 1, and the side that is fitted to the fitting portion 95 of the shield case 90 is defined as the front of the housing 10. Further, the up-down direction is the extending direction of the shielded electric wire 44 orthogonal to the connector fitting direction of the shield connector 1, and the leading-out direction of the shielded electric wire 44 is defined as the downward direction. Furthermore, the left-right direction is the longitudinal direction of the rectangular opening in the fitting portion 11 orthogonal to the connector fitting direction.

[0012] As shown in FIGS. 1 and 2, the shield connector 1 according to this embodiment includes a housing 10, two terminal-attached electric wires 40, a cover 30, and a shield shell 60. This shield connector 1 is, for example, a connector used in a power supply circuit such as an inverter or a motor of a vehicle such as a hybrid vehicle or an electric vehicle. This shield connector 1 is fitted to a fitting portion (mate connector) 95 provided on a shield case (fixed portion) 90 such as an inverter or a motor and is electrically connected.

[0013] As shown in FIGS. 2 and 3, the housing 10 is a substantially L-shaped housing having a fitting portion 11 that houses the tab terminals (terminals) 41 of the terminal-attached electric wires 40 and is fitted to the fitting portion 95, and a wire introduction portion 12 through which the terminals of the shielded electric wires 44 connected to the tab terminals 41 are introduced from the downward direction that intersects the fitting direction (front-back direction in FIG. 2) of the fitting portion 11.

[0014] The fitting portion 11 is formed in a bottomed cylindrical shape having a rectangular opening, and protrudes forward in the fitting direction with the fitting portion 95 in the housing 10. A pair of terminal insertion holes 14 (see FIG. 3) are formed at the bottom of the fitting portion 11. A packing 24 and a front holder 22 are assembled to the outer peripheral portion of the fitting portion 11, and an inner housing 20 having a terminal accommodation chamber 21 is assembled to the inner peripheral portion of the fitting portion 11.

[0015] The wire introduction part 12 extends downward intersecting the fitting direction with the fitting part 95 of the housing 10. A wire insertion hole for inserting the shielded wire 44 is formed in the wire introduction part 12.

[0016] The housing 10 is formed in a concave shape with the rear part on the opposite side of the fitting part 11 being opened by the opening 16, serving as the accommodating part 13. A cover 30 is assembled to the opening 16 on the opposite side of the fitting part 11 at the rear of the housing 10. The housing 10 and the cover 30 are molded from a synthetic resin having electrical insulation properties.

[0017] When the cover 30 is assembled to the housing 10, the opening 16, which is the mounting work hole for the wire 40 with terminals, is covered by the cover 30. A plurality of locking claws 15 project from the outer peripheral surface 10a of the housing 10. Also, a locking projection 17 projects from the upper center of the outer peripheral surface 10a.

[0018] As shown in FIGS. 2 and 3, the cover 30 is formed in a substantially rectangular plate shape and is assembled from the rear side to the opening 16 of the housing 10 via an annular seal member 50. The seal member 50 is attached to the outer peripheral seal surface of the cover 30 and waterproof-seals between the opening 16 of the housing 10 and the cover 30.

[0019] Thereby, the opening 16 of the accommodating part 13 of the housing 10 is hermetically sealed by the cover 30. A plurality of locking pieces 35 having locking holes are formed at the periphery of the cover 30. The locking claws 15 formed on the housing 10 enter the locking holes of these locking pieces 35 when the cover 30 is assembled to the housing 10. Then, each locking piece 35 is locked by the locking claw 15, and the cover 30 is held in a state assembled to the housing 10.

[0020] As shown in Figure 2, the terminal-equipped electric wire 40 consists of a shielded electric wire 44, a tab terminal (terminal) 41 connected to the conductor end of the shielded electric wire 44, a shield terminal 43 connected to the braid (shielding member) of the shielded electric wire 44, and first and second sealing packings 45 and 46 that provide a watertight seal between the electric wire introduction section 12 of the housing 10 and the shielded electric wire 44.

[0021] The shielded wire (cable) 44 is configured as a coaxial cable consisting of a core wire arranged from the center, an inner sheath covering the core wire, a conductive braid covering the inner sheath, and an outer sheath covering the braid.

[0022] The tab terminal 41 is formed from a conductive metal material such as copper, copper alloy, aluminum, or aluminum alloy. This tab terminal 41 is crimped onto the exposed core wire at the end of the shielded wire 44 and electrically connected to the shielded wire 44. This tab terminal 41 is inserted into the electrical connection portion of the mating terminal (not shown) provided on the mating portion 95, and an electrical connection is made.

[0023] The terminal-equipped wire 40, which is assembled to the housing 10, has its shielded wire 44 passed through the wire insertion hole of the wire introduction section 12, and its tab terminal 41 is inserted into the terminal insertion hole 14 of the mating section 11 and housed in the terminal housing chamber 21 of the inner housing 20. In this way, the tab terminal 41 of the terminal-equipped wire 40 is fixed to the mating section 11 of the housing 10.

[0024] Furthermore, each shielded wire 44 of the terminal-equipped wire 40 is fitted with first and second sealing packings 45 and 46. The first sealing packing 45 seals the space between the shield terminal 43 connected to the braid of the shielded wire 44 and the wire introduction section 12. The second sealing packing 46 seals the space between the shielded wire 44 and the shield terminal 43. These first and second sealing packings 45 and 46 seal the space between the shielded wire 44 and the wire introduction section 12.

[0025] As shown in Figures 2 and 3, the shield connector 1 according to this embodiment includes a shield shell 60 composed of an upper shield shell (first shield shell) 61 assembled from the rear side of the housing 10 and a lower shield shell (second shield shell) 62 assembled from below. The upper shield shell 61 is formed by press-forming a metal plate, and the lower shield shell 62 is formed by die-casting molten metal.

[0026] The upper shield shell 61 is formed in a box shape having a substantially rectangular, flat bottom plate portion 63 and peripheral walls 65 that are vertically attached to the periphery of the bottom plate portion 63. The bottom plate portion 63 covers the rear surface of the housing 10, and the peripheral walls 65 cover the top surface and left and right sides (sides) of the housing 10. Below the bottom plate portion 63, a first wire clamping portion 73 is provided for clamping the shield terminal 43 of the terminal-equipped wire 40 extending from the wire introduction portion 12 of the housing 10.

[0027] The upper shield shell 61 is provided with a fixing piece 67 having a hole 67a protruding from the left side of the first wire clamping portion 73, a mounting piece 68 having a hole 68a protruding from the upper right corner of the peripheral wall 65, a pair of through holes 69 formed below the bottom plate portion 63, and a locking hole 75 formed in the upper center of the peripheral wall 65.

[0028] The lower shield shell 62 has a second wire clamping portion 71 for clamping the shield terminal 43 of the terminal-equipped wire 40 extending from the wire introduction portion 12 of the housing 10, and covers the portion of the front of the housing 10 excluding the fitting portion 11. The lower shield shell 62 is also provided with a fixing piece 64 that protrudes from the left side of the second wire clamping portion 71 corresponding to the fixing piece 67 and has a hole 64a, and a pair of screw holes 66 formed above the second wire clamping portion 71 corresponding to a pair of through holes 69.

[0029] Furthermore, the upper shield shell 61 is designed such that when the lower shield shell 62 is fastened and fixed by bolts 81, a clearance G1 (see Figure 6) is created between the opposing surfaces of the overlapping portion 70 formed by the overlapping fixing piece 67 of the first wire clamping portion 73 and the fixing piece 64 of the second wire clamping portion 71. That is, the upper shield shell 61 is integrally formed, for example, during press molding, with the lower end of the first wire clamping portion 73 slightly inclined toward the side away from the second wire clamping portion 71.

[0030] Next, we will describe how to assemble the shield connector 1 according to this embodiment. First, as shown in Figure 3, the shielded wire 44 of the terminal-equipped wire 40 is passed through the wire entry section 12 of the housing 10, and the tab terminal 41 is pulled out towards the housing section 13. Then, the tab terminal 41 is inserted into the terminal insertion hole 14 of the housing 10.

[0031] Then, the cover 30 is brought close to the housing portion 13 of the housing 10 so as to cover the opening 16 from the rear side, and the locking claws 15 of the housing 10 are locked into the locking pieces 35 of the cover 30. As a result, the sealing member 50 attached to the housing 10 provides a waterproof seal between the opening 16 of the housing 10 and the cover 30.

[0032] Next, the shield shell 60 is attached to the housing 10. First, the upper shield shell 61 of the shield shell 60 is attached from the rear so as to cover the housing 10 to which the cover 30 is assembled. In this case, the upper shield shell 61 is attached to the rear of the housing 10 by first engaging the locking hole 75 with the locking projection 17 of the housing 10, and then placing the first wire clamping portion 73 over the wire entry portion 12.

[0033] Next, the lower shield shell 62 of the shield shell 60 is attached from below so as to cover the wire entry portion 12 of the housing 10. The upper shield shell 61 and the lower shield shell 62 are then attached to the housing 10, with the through hole 69 of the upper shield shell 61 and the screw hole 66 of the lower shield shell 62 being in communication with each other. Subsequently, the upper shield shell 61 and the lower shield shell 62 are fixed to the housing 10 by inserting the bolt 81 into the through hole 69 and screwing it into the screw hole 66.

[0034] Here, the upper shield shell 61 and lower shield shell 62 fixed to the housing 10 are configured such that a clearance G1 is created between the opposing surfaces of the overlapping portion 70 formed by the overlapping fixing piece 67 of the first wire clamping portion 73 and the fixing piece 64 of the second wire clamping portion 71 (see Figure 6). Therefore, even if there are variations in manufacturing tolerances of the upper shield shell 61 and lower shield shell 62, the overlapping portion 70 will not come into contact first when the bolt 81 is fastened, and the bolt 81 can be fully seated.

[0035] Therefore, the shield connector 1 of this embodiment can ensure sufficient fastening force through the axial force of the bolt 81, the contact force between the upper shield shell 61 and the lower shield shell 62 does not weaken, and the shielding performance of the shield shell 60 does not deteriorate.

[0036] Furthermore, the upper shield shell 61 and the lower shield shell 62 are electrically connected to each other via bolts 81. In addition, one end of the braided shield wire 44 is electrically connected to the shield shell 60 by the shield terminal 43 of the terminal-equipped wire 40.

[0037] Next, the procedure for fixing the shield connector 1 according to this embodiment to the shield case 90 will be described. First, as shown in Figure 4, the mating portion 11 of the shield connector 1 with the above structure is fitted into the mating portion 95 provided on the shield case 90. As a result, the tab terminal 41 inside the mating portion 11 is inserted into the electrical connection portion of the mating terminal and electrically connected. When the shield connector 1 is fitted into the mating portion 95, the packing 24 adheres tightly to the inner circumferential surface of the mating portion 95. This seals the mating area between the shield connector 1 and the mating portion 95.

[0038] Then, when the shield connector 1 is fitted into the mating portion 95, the mounting piece 68 of the upper shield shell 61 is placed on the fixing boss 91 of the shield case 90, and the double-layered portion 70 of the shield shell 60 is placed on the fixing boss 92 of the shield case 90. As a result, the hole 68a of the mounting piece 68 and the screw hole 93 of the fixing boss 91 are in communication, and the holes 64a and 67a of the fixing pieces 64 and 67 are in communication with the screw hole 94 of the fixing boss 92.

[0039] Therefore, as shown in Figure 5, the fixing bolt 83 inserted into the hole 68a of the mounting piece 68 of the upper shield shell 61 is screwed into the threaded hole 93 of the fixing boss 91, and the fixing bolt 83 inserted into the holes 64a and 67a of the fixing pieces 64 and 67 is screwed into the threaded hole 94 of the fixing boss 92. Then, the fastening force of the fixing bolt 83 pushes the shield connector 1 toward the mating portion 95. This makes it possible to easily mate the shield connector 1 toward the mating portion 95.

[0040] In the shield connector 1 according to this embodiment, a clearance G1 is provided between the opposing surfaces of the two overlapping portions 70, and fixing bolts 83 are fastened and secured to the fixing piece 67 of the upper shield shell 61 and the fixing piece 64 of the lower shield shell 62 against the repulsive force that causes them to move away from each other.

[0041] That is, as shown in Figure 6, just before the shield connector 1 is fixed to the mating portion 95, there is a clearance G1 defined between the opposing surfaces of the two overlapping portions 70 by the first wire clamping portion 73, which is cantilevered by the fastening and fixing of the bolt 81. When the fixing bolt 83 is fastened, as shown in Figure 7, the fixing piece 67 of the upper shield shell 61 elastically deforms in a direction that compresses the clearance G1, generating a repulsive force. However, the fixing bolt 83, which is larger than the bolt 81, can generate a sufficient axial force.

[0042] Therefore, the contact force between the upper shield shell 61 and the lower shield shell 62 will not be weakened due to insufficient axial force of the bolt 81, and the smallest necessary bolt can be used as the bolt 81 for fastening and fixing the upper shield shell 61 and the lower shield shell 62, making it possible to miniaturize the product.

[0043] Furthermore, the fixing bolts 83 that secure the shield connector 1 to the shield case 90 fasten the fixing piece 67 of the upper shield shell 61 and the fixing piece 64 of the lower shield shell 62 together. This ensures that even if the axial force of the bolts 81 is insufficient, the shield shell 60 is reliably electrically connected to the shield case 90. As a result, the shield connector 1 is covered by the shield shell 60 fixed to the shield case 90, providing a good electromagnetic shielding effect.

[0044] Furthermore, in the shield connector 1 according to this embodiment, the first wire clamping portion 73 of the upper shield shell 61 and the second wire clamping portion 71 of the lower shield shell 62 are electrically connected to the braid of the terminal-equipped wire 40 by clamping the shield terminal 43 of the terminal-equipped wire 40 housed in the housing 10.

[0045] Therefore, by fastening the fixing piece 67 of the upper shield shell 61 and the fixing piece 64 of the lower shield shell 62 with the fixing bolt 83, as shown in Figure 8, the load P that the first wire clamping portion 73 of the upper shield shell 61 and the second wire clamping portion 71 of the lower shield shell 62 clamp onto the shield terminal 43 of the terminal-equipped wire 40 increases, and the contact resistance can be reduced.

[0046] (Reference example) Figure 9 is a cross-sectional view of the main part showing the state of the shield connector 1A according to the reference example immediately before it is fixed to the part to be fixed. The shield connector 1A in the reference example differs from the embodiment described above in that the shape of the upper shield shell 61A is different. In the following, the same reference numerals are used for parts that are the same as in the embodiment described above, and their descriptions are omitted.

[0047] As shown in Figure 9, the upper shield shell 61A in the reference example has its external dimensions set such that when the lower shield shell 62 is fastened and fixed by bolts 81, no clearance G1 is created between the opposing surfaces of the overlapping portion 70 formed by the overlapping fixing piece 67 of the first wire clamping portion 73 and the fixing piece 64 of the second wire clamping portion 71. That is, the upper shield shell 61A is integrally formed, for example, during press molding, so that the first wire clamping portion 73 is in surface contact with the second wire clamping portion 71.

[0048] Therefore, if there are variations in the manufacturing tolerances of the upper shield shell 61A and the lower shield shell 62, the overlapping portion 70 may come into contact first when the bolt 81 is fastened, potentially creating a clearance G2 between the bottom plate portion 63 of the upper shield shell 61A and the lower shield shell 62.

[0049] Therefore, in the example shield connector 1A, there is a risk that the bolt 81 may not be able to fully seat, and sufficient fastening force cannot be secured by the axial force of the bolt 81. This may result in a weakened contact force between the upper shield shell 61A and the lower shield shell 62, potentially reducing the shielding performance of the shield shell 60A.

[0050] In contrast, the shield connector 1 of this embodiment described above can stably maintain the shielding performance of the shield shell 60.

[0051] Furthermore, in the shield connector 1 according to this embodiment, the upper shield shell 61 is formed by press-forming a metal plate, and the lower shield shell 62 is formed by die-casting. Therefore, by simply setting the external dimensions of the press-formed upper shield shell 61 appropriately, the dimension of the clearance G1 defined between the opposing surfaces of the two overlapping portions 70 can be easily controlled.

[0052] Furthermore, in the shield connector 1 according to this embodiment, the upper shield shell 61 has a bottom plate portion 63 that covers the rear surface of the housing 10 and a peripheral wall 65 that is vertically attached to the periphery of the bottom plate portion 63 and covers the side surface of the housing 10. Therefore, the shield connector 1 can obtain a good electromagnetic shielding effect with simple assembly work.

[0053] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention. For example, in the above embodiment, an example was described in which the lower shield shell 62 was formed by die casting, but it may also be formed by press molding.

[0054] Herein, the features of the embodiments of the shielded connector according to the present invention described above are briefly summarized and listed below in [1] to [5]. [1] A housing (10) having a mating portion (11) that is mated with a mating portion (95) on the other side, A first shield shell (upper shield shell 61) is fitted onto the housing (10) so as to cover the back surface opposite to the fitting portion (11), A second shield shell (lower shield shell 62) covers the portion of the front surface of the housing (10) excluding the fitting portion (11), A bolt (81) fastens and secures the first shield shell (upper shield shell 61) to the second shield shell (lower shield shell 62), A fixing bolt (83) fastens and secures the overlapping portion (70) formed by overlapping the fixing piece (67) of the first shield shell (upper shield shell 61) and the fixing piece (64) of the second shield shell (lower shield shell 62) to the part to be fixed (shield case 90), A shielded connector (1) equipped with [a specific feature].

[0055] According to the shield connector (1) with the configuration described in [1] above, the fixing bolt (83) that fastens the shield connector (1) to the fixed part (shield case 90) fastens the fixing piece (67) of the first shield shell (upper shield shell 61) and the fixing piece (64) of the second shield shell (lower shield shell 62) together. This ensures that even if the axial force of the bolt (81) is insufficient, the first shield shell (upper shield shell 61) and the second shield shell (lower shield shell 62) are electrically and reliably connected to the fixed part (shield case 90). As a result, the shield connector (1) is covered by the first shield shell (upper shield shell 61) and the second shield shell (lower shield shell 62) fixed to the fixed part (shield case 90), providing a good electromagnetic shielding effect.

[0056] [2] A clearance (G1) is provided between the opposing surfaces of the two overlapping portions (70), and the fixing bolts (83) are fastened and fixed against the repulsive force that causes the fixing piece (67) of the first shield shell (upper shield shell 61) and the fixing piece (64) of the second shield shell (lower shield shell 62) to move away from each other. The shield connector (1) described in [1] above.

[0057] With the shield connector (1) configured as described in [2] above, even if there are variations in manufacturing tolerances between the first shield shell (upper shield shell 61) and the second shield shell (lower shield shell 62), the overlapping portion (70) will not come into contact first when the bolt (81) is fastened, and the bolt (81) will be able to seat completely. Therefore, the shield connector (1) configured in this way can ensure sufficient fastening force through the axial force of the bolt (81), and the contact force between the first shield shell (upper shield shell 61) and the second shield shell (lower shield shell 62) will not weaken, thus preventing a decrease in shielding performance.

[0058] [3] The first wire clamping portion (73) of the first shield shell (upper shield shell 61) and the second wire clamping portion (71) of the second shield shell (lower shield shell 62) are electrically connected to the shield member (braid) of the terminal-equipped wire (40) housed in the housing (10) by clamping the shield terminal (43) of the terminal-equipped wire (40). The shield connector (1) described in [2] above.

[0059] According to the shield connector (1) with the configuration described in [3] above, the fixing piece (67) of the first shield shell (upper shield shell 61) and the fixing piece (64) of the second shield shell (lower shield shell 62) are fastened together by fixing bolts (83), thereby increasing the load (P) on which the first wire clamping portion (73) of the first shield shell (upper shield shell 61) and the second wire clamping portion (71) of the second shield shell (lower shield shell 62) clamp the shield terminal (43) of the terminal-equipped wire (40), and reducing contact resistance.

[0060] [4] The first shield shell (upper shield shell 61) is formed by press-forming a metal plate, The second shield shell (lower shield shell 62) is formed by die-casting. A shielded connector (1) as described in any one of the above [1] to [3].

[0061] According to the shield connector (1) with the configuration described in [4] above, the dimensions of the clearance (G1) defined between the opposing surfaces of the two overlapping portions (70) can be easily controlled simply by appropriately setting the external dimensions of the press-formed first shield shell (upper shield shell 61).

[0062] [5] The first shield shell (upper shield shell 61) has a bottom plate portion (63) that covers the rear surface of the housing (10) and a peripheral wall (65) that is perpendicular to the periphery of the bottom plate portion (63) and covers the side surface of the housing (10), The shield connector (1) described in [4] above.

[0063] According to the shield connector (1) in the configuration described in [5] above, a good electromagnetic shielding effect can be obtained with simple assembly work. [Explanation of Symbols]
