Description

[Technical field]

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

[0002] Conventionally, as disclosed in, for example, Patent Documents 1 to 3, a shielded connector to be mounted on a device case includes a synthetic resin housing formed in a substantially L-shape and having a fitting portion that houses a terminal connected to an end of an electric wire and is fitted to a device-side connector (mating connector), and an electric wire introduction portion through which an electric wire connected to the terminal is introduced from a direction intersecting with the fitting direction of the fitting portion. The housing has a working hole (opening) formed on the opposite side to the fitting portion, and a cover is attached to the working hole. A conductive metallic shield shell covers the outside of the housing.

[0003] A seal ring (annular seal member) is attached to the outer seal surface of the cover, which seals the inside of the housing by closely contacting the inner surface (inner seal surface) of the working hole. The cover is attached to the working hole to protect the housing from water and other substances entering through the working hole. In other words, the seal ring seals between the inner seal surface of the working hole and the outer seal surface of the cover. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2014-86150 A [Patent Document 2] JP 2015-82466 A [Patent Document 3] Patent Publication No. 2022-2194 Summary of the Invention [Problem to be solved by the invention]

[0005] However, if the inner seal surface of the working hole is subjected to the reaction force of the seal ring in a high temperature environment and creeps outward, this can lead to a drop in seal pressure. Therefore, it can be considered to provide multiple ribs along the outer circumferential surface of the housing that corresponds to the outside of the working hole to suppress creep deformation of the inner seal surface.

[0006] However, if a rib extending along the assembly direction of the shield shell is provided on the outer periphery of the housing, the rib may come into strong contact with the shield shell when assembling the housing to the shield shell, which may increase the force required for assembly and reduce workability.

[0007] The present invention has been made in consideration of the above-mentioned circumstances, and an object of the present invention is to provide a shielded connector that can suppress creep deformation of the housing without impairing assembly ease. [Means for solving the problem]

[0008] The above object of the present invention can be achieved by the following configuration. a housing having a mating portion to be mated with a mating connector; a cover attached to the opening on the opposite side to the fitting portion; an annular seal member that seals between an inner circumferential seal surface of the opening and an outer circumferential seal surface of the cover; a shield shell fitted onto the housing so as to cover the opening; a plurality of ribs disposed along an outer circumferential surface of the housing corresponding to the outside of the opening and extending along an assembly direction of the shield shell; a contact surface that protrudes from an inner surface of the shield shell so as to suppress deformation of the opening in a radial expansion direction by contacting only an end of the rib at an opening end of the opening when the shield shell is assembled to the housing; 1. A shielded connector comprising: Effect of the Invention

[0009] According to the present invention, it is possible to provide a shielded connector that can suppress creep deformation of a housing without impairing ease of assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. (Embodiment) 1 and 2 are a perspective view and an exploded perspective view of a shielded connector 1 according to an embodiment of the present invention. In this specification, the front-rear direction, the up-down direction, and the left-right direction of the shielded connector 1 correspond to the directions of the arrows shown in Fig. 1 to Fig. 3. That is, the front-rear direction is the direction along the connector fitting direction of the shielded connector 1, and the side where a mating connector (not shown) is fitted is defined as the front of the housing 10. The up-down direction is the extension direction of the shielded electric wire 44 perpendicular to the connector fitting direction of the shielded connector 1, and the direction in which the shielded electric wire 44 is led out is defined as the downward direction. Furthermore, the left-right direction is the longitudinal direction of a rectangular opening in the bottomed tubular fitting portion 11 perpendicular to the connector fitting direction.

[0013] 1 and 2, the shielded connector 1 according to this embodiment includes a housing 10, two electric wires 40 with terminals, a cover 30, a seal member 50, and a shielded shell 60. This shielded connector 1 is a connector used in a power supply circuit of an inverter, a motor, etc. of a vehicle such as a hybrid vehicle or an electric vehicle. This shielded connector 1 is fitted into a mating connector provided in a case of the inverter, motor, etc., and is electrically connected.

[0014] As shown in Figs. 2 and 3, the housing 10 is a generally L-shaped housing having a fitting portion 11 that receives a tab terminal (terminal) 41 of the terminal-fitted electric wire 40 and is fitted into an equipment-side connector (mating connector), and an electric wire introduction portion 12 into which an end of a shielded electric wire 44 connected to the tab terminal 41 is introduced from a direction intersecting with the fitting direction X (see Fig. 1) of the fitting portion 11.

[0015] The fitting portion 11 is formed in a bottomed cylindrical shape having a rectangular opening, and protrudes forward in a fitting direction X with a mating connector in the housing 10. A pair of terminal insertion holes 14 (see FIG. 6) are formed in the bottom of the fitting portion 11. A packing 24 and a front holder 22 are attached to the outer periphery of the fitting portion 11 , and an inner housing 20 having terminal accommodating chambers 21 is attached to the inner periphery of the fitting portion 11 .

[0016] The electric wire introduction portion 12 extends downward intersecting with a fitting direction X of the housing 10 with a mating connector. The electric wire introduction portion 12 is formed with an electric wire insertion hole 18 (see FIG. 7) through which a shielded electric wire 44 is inserted.

[0017] The housing 10 has a rear portion opposite the fitting portion 11 that serves as a receiving portion 13 formed in a recessed shape with an opening 16. A cover 30 is attached to the opening 16 on the rear portion of the housing 10 opposite the fitting portion 11. The housing 10 and the cover 30 are molded from an electrically insulating synthetic resin. When the cover 30 is attached to the housing 10, the opening 16, which is an attachment hole for the terminal-fitted electric wire 40, is covered by the cover 30.

[0018] 6 and 7, a plurality of ribs 17 are disposed along the outer peripheral surface 10a of the housing 10 corresponding to the outside of the opening 16. The ribs 17 are protrusions having a rectangular cross section and extending along the assembly direction of an upper shield shell 61, which will be described later. Furthermore, a plurality of locking claws 15 are protrudingly provided on the outer peripheral surface 10a of the housing 10. As shown in FIG. 3, a plurality of reinforcing ribs 19 are provided at the inner corners of the storage section 13 to suppress deformation of the storage section 13.

[0019] As shown in FIGS. 2 and 3, the cover 30 is formed in a substantially rectangular plate shape, and is attached to the opening 16 of the housing 10 from the rear side with an annular seal member 50 interposed therebetween. 2, the seal member 50 is composed of a seal body 51 formed in an annular shape from an elastic material such as rubber, and a number of T-shaped locking pieces 53 that protrude toward the center from the rear end side in the insertion direction of the seal body 51. The T-shaped locking pieces 53 each have a tip end formed in a T shape that extends to the left and right.

[0020] An outer lip 51a is provided on the outer peripheral surface of the seal body 51, which fits closely to the inner peripheral seal surface 16a of the opening 16. In addition, an inner lip 51b is provided on the inner peripheral surface of the seal body 51, which fits closely to the outer peripheral seal surface 31 of the cover 30.

[0021] The seal member 50 is attached to the outer peripheral seal surface 31 of the cover 30, and provides a waterproof seal between the opening 16 of the housing 10 and the cover 30. The T-shaped locking pieces 53 of the seal member 50 are locked in the locking recesses 33 formed on the outer peripheral edge of the cover 30, thereby restricting movement of the seal member 50 in the insertion direction X.

[0022] As a result, the opening 16 of the accommodating portion 13 of the housing 10 is watertightly sealed by the cover 30. A plurality of locking pieces 35 having locking holes are formed on the periphery of the cover 30. When the cover 30 is assembled to the housing 10, the locking claws 15 formed on the housing 10 fit into the locking holes of the locking pieces 35. The locking pieces 35 are then locked by the locking claws 15, and the cover 30 is maintained in an assembled state with respect to the housing 10.

[0023] As shown in FIG. 2, the electric wire with terminal 40 includes 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 of the shielded electric wire 44, and rubber plugs 45, 46 that provide a waterproof seal between the electric wire introduction portion 12 of the housing 10 and the shielded electric wire 44.

[0024] The shielded electric wire (electric wire) 44 is configured as a coaxial cable consisting of a core wire arranged from the center, an inner coating covering the core wire, a conductive braid covering the inner coating, and an outer sheath covering the braid.

[0025] The tab terminal 41 is made of a conductive metal material such as copper, a copper alloy, aluminum, an aluminum alloy, etc. The tab terminal 41 is crimped to the core wire exposed at the end of the shielded electric wire 44, and is electrically connected to the shielded electric wire 44. This tab terminal 41 is inserted into an electrical connection portion of a mating terminal (not shown) provided on a mating connector, and is electrically connected.

[0026] The electric wire with terminal 40 to be assembled to the housing 10 has the shielded electric wire 44 passed through the electric wire insertion hole 18 of the electric wire introduction portion 12 and the tab terminal 41 inserted into the terminal insertion hole 14 of the fitting portion 11 to be accommodated in the terminal accommodating chamber 21 of the inner housing 20. As a result, the tab terminal 41 of the electric wire with terminal 40 is fixed to the fitting portion 11 of the housing 10.

[0027] Further, rubber plugs 45, 46 are attached to each shielded electric wire 44 of the electric wire with terminal 40. The rubber plug 45 seals between the shielded terminal 43 connected to the braid of the shielded electric wire 44 and the electric wire introduction portion 12. The rubber plug 46 seals between the shielded electric wire 44 and the shielded terminal 43. The rubber plugs 45, 46 seal between the shielded electric wire 44 and the electric wire introduction portion 12.

[0028] 2 and 3, the shielded connector 1 according to this embodiment includes a shield shell 60 composed of an upper shield shell 61 that is assembled from the rear side of the housing 10, and a lower shield shell 62 that is assembled from the lower side. The upper shield shell 61 and the lower shield shell 62 are each formed from a conductive metal material.

[0029] The upper shield shell 61 is formed in a box shape having a bottom plate portion 63 having a substantially rectangular flat plate shape and a peripheral wall 65 vertically extending from the peripheral edge of the bottom plate portion 63. The bottom plate portion 63 covers the rear surface of the housing 10, and the peripheral wall 65 covers the top surface and the left and right side surfaces (side surfaces) of the housing 10. The upper shield shell 61 is also provided with a fixing piece 67 having a hole portion formed therein and a through hole 69.

[0030] Furthermore, at left and right corners between the bottom plate portion 63 and the peripheral wall 65 of the upper shield shell (shield shell) 61, a plurality of contact surfaces 70 are protruded from the inner surface of the peripheral wall 65. These contact surfaces 70 can be formed integrally when the upper shield shell 61 is press-molded, for example.

[0031] When assembled to cover the rear surface of the housing 10, the abutment surface 70 is provided so as to correspond to a position including at least the ribs 17 arranged line-symmetrically to one another among the multiple ribs 17 protruding from the outer peripheral surface 10a of the housing 10. Note that in this embodiment, the abutment surface 70 is provided so as to correspond to the positions of the ribs 17 arranged on the left and right side surfaces along the longitudinal direction (up-down direction) of the housing 10. This is because creep deformation is more likely to occur on the left and right side surfaces of the housing 10 along the longitudinal direction than on the top surface of the housing 10 along the lateral direction.

[0032] Further, the peripheral wall 65 of the upper shield shell 61 has an outer dimension set so that the inner surface does not come into strong contact with the plurality of ribs 17 protruding from the outer circumferential surface 10 a of the housing 10 .

[0033] The abutment surface 70 is provided on the inner side of the recessed corner of the peripheral wall 65 so that only the end of the rib 17 at the open end of the opening 16 comes into contact with the abutment surface 70. The abutment surface 70 is set to a protruding height that allows the abutment surface 70 to reliably come into contact with the tip of the rib 17. That is, when the upper shield shell 61 is assembled to the housing 10, the abutment surface 70 comes into contact with the tip of the rib 17.

[0034] The lower shield shell (shield shell) 62 covers the front surface of the housing 10 except for the fitting portion 11. The lower shield shell 62 is provided with a fixing piece 64 having a hole and a screw hole 66.

[0035] Next, a method of assembling the shield connector 1 according to this embodiment will be described. First, as shown in FIG. 3 , the shielded wire 44 of the terminal-attached wire 40 is passed through the wire introduction portion 12 of the housing 10, and the tab terminal 41 is pulled out toward the accommodating portion 13. Then, the tab terminal 41 is inserted into the terminal insertion hole 14 of the housing 10.

[0036] Then, the cover 30 is brought close to the receiving portion 13 of the housing 10 so as to cover the opening 16 from the rear side thereof, and the locking claws 15 of the housing 10 are locked with the locking pieces 35 of the cover 30 . 8, the seal member 50 attached such that the inner lip 51b is in close contact with the outer peripheral seal surface 31 of the cover 30 has the outer lip 51a in close contact with the inner peripheral seal surface 16a of the opening 16. Thus, the seal member 50 attached to the housing 10 can provide a waterproof seal between the opening 16 of the housing 10 and the cover 30.

[0037] Next, the shield shell 60 is attached to the housing 10 . First, as shown in FIG. 8, the upper shield shell 61 of the shield shell 60 is attached from the rear side so as to cover the housing 10 to which the cover 30 is attached. At this time, the inner surface of the peripheral wall 65 of the housing 10 comes into sliding contact with the multiple ribs 17 protruding from the outer circumferential surface 10a of the housing 10, but does not come into strong contact with the ribs 17. Thus, in the state in which the upper shield shell 61 is in the middle of being assembled to the housing 10, there is no risk of the force required to assemble the upper shield shell 61 increasing and deteriorating workability.

[0038] As shown in FIG. 9, when the upper shield shell 61 is assembled to the housing 10, the abutment surface 70 protruding from the inner surface of the peripheral wall 65 contacts the end of the rib 17 at the opening end of the opening 16, suppressing deformation of the opening 16 in the radial expansion direction.

[0039] The lower shield shell 62 of the shield shell 60 is attached from below so as to cover the electric wire introduction portion 12 of the housing 10 . Then, the upper shield shell 61 and the lower shield shell 62 are attached to the housing 10, and the through holes 69 of the upper shield shell 61 are communicated with the screw holes 66 of the lower shield shell 62. Thereafter, mounting screws (not shown) are inserted into the through holes 69 and screwed into the screw holes 66, thereby fixing the upper shield shell 61 and the lower shield shell 62 to the housing 10.

[0040] The upper shield shell 61 and the lower shield shell 62 are electrically connected to each other via mounting screws. Furthermore, one end of the braid of the shielded electric wire 44 is electrically connected to the shield shell 60 by the shield terminal 43 of the electric wire with terminal 40.

[0041] The mating portion 11 of the shielded connector 1 having the above structure is mated with a mating connector provided on a case of an inverter, a motor, or the like. As a result, the tab terminal 41 in the mating portion 11 is inserted into the electrical connection portion of the mating terminal and electrically connected. When the shielded connector 1 is mated with the mating connector, the packing 24 adheres closely to the housing of the mating connector. This seals the mating portion between the shielded connector 1 and the mating connector.

[0042] Furthermore, when mating the shielded connector 1 with the mating connector, a bolt (not shown) inserted into the hole of the fixing piece 67 of the upper shield shell 61 and the hole of the fixing piece 64 of the lower shield shell 62 is screwed into a screw hole (not shown) formed in the case. Then, the fastening force of the bolt presses the shielded connector 1 toward the mating connector. This allows the shielded connector 1 to be easily mated with the mating connector.

[0043] Furthermore, the fixing piece 67 of the upper shield shell 61 and the fixing piece 64 of the lower shield shell 62 are fastened together with a bolt, thereby electrically connecting the shield shell 60 to the case. As a result, the shield connector 1 is covered by the shield shell 60 fixed to the case, and a good electromagnetic shielding effect is obtained.

[0044] When the above-mentioned shielded connector 1 is mounted on a vehicle, in a high temperature environment, the inner peripheral seal surface 16a of the opening 16 in the housing 10 tends to creep outward due to the repulsive force of the seal member 50. However, abutment surface 70 protruding from the inner surface of the peripheral wall 65 of the upper shield shell 61 comes into contact with the tip of the rib 17 at the open end of the opening 16, thereby suppressing deformation of the opening 16 in the radial expansion direction.

[0045] Therefore, the shielded connector 1 of the present embodiment can suppress outward creep deformation of the inner sealing surface 16a of the opening 16 in the housing 10. As a result, a decrease in the sealing pressure of the sealing member 50 can be prevented, and a good waterproof seal can be ensured.

[0046] (Reference example) 10 and 11 are horizontal cross-sectional views showing a state immediately before and during assembly of an upper shield shell 61A of a shield connector 1A according to a reference example to a housing 10. FIG. The shielded connector 1A of the reference example differs from the above embodiment in that the shape of the upper shield shell 61 A is different. In the following, the same parts as those in the above embodiment are given the same reference numerals and the description thereof will be omitted.

[0047] As shown in FIG. 10, an upper shield shell 61A according to the reference example does not have abutment surfaces 70 protruding from the left and right recessed corners between a bottom plate portion 63 and a peripheral wall 65. As shown in FIG. Further, the peripheral wall 65 of the upper shield shell 61A has an outer dimension set so that the inner surface thereof comes into contact with the plurality of ribs 17 protruding from the outer circumferential surface 10a of the housing 10.

[0048] Therefore, when the upper shield shell 61A is assembled to the housing 10, the inner surface of the peripheral wall 65 comes into contact with the rib 17 at the open end of the opening 16, thereby suppressing deformation of the opening 16 in the radial expansion direction.

[0049] However, as shown in FIG. 11, when the upper shield shell 61A is in the process of being assembled to the housing 10, the inner surface of the peripheral wall 65 may come into sliding contact with multiple ribs 17 protruding from the outer peripheral surface 10a of the housing 10 and may come into strong contact with the ribs 17. Therefore, in the shielded connector 1A of the reference example, the force required for assembling the upper shield shell 61A increases, which may reduce workability.

[0050] In contrast, according to the shielded connector 1 of the present embodiment, creep deformation of the housing 10 can be suppressed without impairing the ease of assembly.

[0051] In addition, in the shielded connector 1 according to this embodiment, the shielded shell 60 is composed of an upper shielded shell 61 that is assembled to the housing 10 so as to cover the opening 16 on the rear surface of the housing 10, and a lower shielded shell 62 that is assembled to the housing 10 so as to cover the portion of the front surface of the housing 10 excluding the fitting portion 11. The upper shielded 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 top surface and the left and right side surfaces of the housing 10. Thus, the shielded connector 1 can obtain a good electromagnetic shielding effect with a simple assembly operation.

[0052] Moreover, in the shielded connector 1 according to this embodiment, the abutment surface 70 is formed to protrude from the inner surface of the peripheral wall 65 at the recessed corner between the bottom plate portion 63 and the peripheral wall 65. Thus, for example, when the upper shield shell 61 is press-molded, the abutment surface 70 can be easily formed integrally.

[0053] The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited. For example, in the above embodiment, the shield shell 60 including the upper shield shell 61 and the lower shield shell 62 is press-molded, but it may be molded by die casting, metal injection molding, or the like.

[0054] Here, the features of the above-described embodiments of the shielded connector according to the present invention will be briefly summarized and listed in the following [1] to [3].
