Description

  The present invention relates to a connection structure between a device and a shielded cable.

  Conventionally, when power is supplied to a motor mounted on an electric vehicle, a hybrid vehicle, or the like, a shielded cable having an outer conductor that shields between the inner conductor of the shielded cable and another circuit is used. The inner conductor of the shielded cable is connected to the terminal fitting, and the outer conductor of the shielded cable is connected to the case body of the device by the shield bracket. On the other hand, a bus bar is routed inside the case body of the device, and a terminal block connected to the terminal fitting is integrally provided on the bus bar (for example, see Patent Document 1 below).

As a connection structure between such a device and a shielded cable, for example, the configuration shown in FIG. 10 can be considered. The case body 100 includes a mounting hole 140 into which a molded connector 160 in which a terminal fitting 130 is integrally molded can be mounted. Furthermore, the case body 100 includes a mounting hole 120 at a position corresponding to the terminal block 110, in addition to the mounting hole 140, and a tool or the like enters the case body 100 through the mounting hole 120 to tighten the bolt. Thus, the terminal fitting 130 and the terminal block 110 are connected. After the terminal fitting 130 and the terminal block 110 are connected, the entry of water into the case body 100 is restricted by attaching a dedicated cover 150 to the attachment hole 120. Thereafter, the shield bracket 170 is attached from the mounting hole 140 to the molded connector 160 so that the gap between the two 140 and 160 is shielded.
JP 2002-134953 A

  However, in the above configuration, the mounting hole 140 and the mounting hole 120 are independently provided at different locations, and it is necessary to attach the shield bracket 170 and the cover 150 separately. Further, since it is necessary to attach the shield bracket 170 to the mounting hole 140 after the terminal fitting 130 is fixed to the terminal block 110, it is necessary to adopt a structure (alignment structure) capable of adjusting the position of the shield bracket 170. A gap S was easily formed between 160 and the shield bracket 170, and the shield function was not stable.

  The present invention has been completed based on the above circumstances, and it is an object of the present invention to facilitate the mounting of a shield bracket and to stabilize the shield function of the shield bracket.

  The present invention includes a case body that covers devices such as an inverter and a motor, a bus bar that is routed inside the case body and that forms a terminal block, and an attachment that is provided on the case body and exposes the terminal block to the outside of the case body Connected to the outer conductor of the shield cable, a plurality of terminal fittings having a hole, a bus bar connection portion connected to the bus bar on one end side, and a cable connection portion connected to the inner conductor of the shield cable on the other end side In addition, the shield cable is connected to a device having a shield bracket that shields between the end of the shield cable and the outer surface of the case body by covering the outer periphery of a plurality of terminal fittings at once. The hole is characterized in that it is configured to be closed by a shield bracket.

  According to such a configuration, a tool or the like enters the inside of the case body through the attachment hole, and after connecting the terminal metal fitting and the bus bar, the shield bracket is attached to the case body to attach the shield bracket to the outer surface of the case body. And the mounting hole can be closed by the shield bracket.

The following configuration is preferable as an embodiment of the present invention.
The plurality of terminal fittings are integrally molded by a mold body, and individual insertion holes are provided for the respective terminal fittings at positions corresponding to the mounting holes in the molding body, and the opening edge portions of these insertion holes and shields are provided. It is good also as a structure by which the sheet-like sealing member is interposed in the mating surface with a bracket.

  According to such a structure, it can seal by pinching | interposing a sheet-like sealing member with the mating surface of the opening edge part of an insertion hole, and a shield bracket. On the other hand, as shown in FIG. 10, the cylindrical portion 151 of the cover 150 is fitted inside the mounting hole 120, and the seal member 152 is axially disposed between the inner peripheral surface of the mounting hole 120 and the outer peripheral surface of the cylindrical portion 151. When sealing along, the insertion force at the time of attaching the cover 150 to the attachment hole 120 becomes large. In that respect, since the present invention adopts a so-called face seal structure, the shield bracket can be easily attached. As a result, it is not necessary to provide an alignment structure between the shield bracket and the mold body, and a gap due to the alignment structure is not formed, so that the shield function can be stabilized.

  Between the opening edge of the mounting hole and the shield bracket, an annular packing and a spacer housed inside the packing are mounted, and this spacer constitutes an inner peripheral wall of a housing groove for housing the packing. It is good also as a structure.

  According to such a structure, it can seal by pinching an annular packing between the opening edge part of an attachment hole, and a shield bracket. That is, since the so-called face seal structure is adopted, the shield bracket can be easily attached. Moreover, since the bending to the inner side of the packing is regulated by the spacer, the sealing function is not deteriorated.

  According to the present invention, the shield bracket can be easily attached and the shield function of the shield bracket can be stabilized.

  The mold body 42 is made of synthetic resin and melted in a mold (not shown) in which three terminal fittings 41 to which the core wire 61 of the shield cable 6 is connected are set in parallel on the left and right. It is molded by injecting resin and is integrated with the three terminal fittings 41 and the end of the shield cable 6.

  As shown in FIGS. 6 and 8, the mold body 42 has a substantially L shape corresponding to the shape of the terminal fitting 41, and is attached to one end side of the mold body 42 as shown in FIG. A fitting portion 47 that fits into the hole 31 is formed. In this fitting portion 47, individual insertion holes 46 that expose the three bus bar connecting portions 43 on both sides in the fitting direction with respect to the mounting hole 31 are formed. Has been.

  A mounting groove 47 </ b> A in which a ring-shaped seal member 71 is mounted is provided on the outer peripheral surface of the fitting portion 47. When the fitting part 47 is fitted into the mounting hole 31 in a state where the sealing member 71 is mounted in the mounting groove 47A, the sealing member 71 is connected to the outer peripheral surface of the fitting part 47 and the inner peripheral surface of the mounting hole 31. Intrusion of water into the inside of the case body 3 is restricted.

  On the other hand, a mounting surface 48 on which the shield bracket 5 is mounted is formed at the opening on the shield cable 6 side of the opening at both ends of the insertion hole 46. As shown in FIG. 7, a sheet-like seal member 72 is attached to a portion of the attachment surface 48 excluding the three insertion holes 46. The seal member 72 is secured in a state of penetrating through a plurality of retaining pieces 48 </ b> A provided protruding from the mounting surface 48.

  Three projecting portions 49 extending along the extending direction of the shielded cable 6 are formed on the other end side of the mold body 42 (on the side opposite to the fitting portion 47). As shown in FIG. 7, each protrusion 49 has a substantially square cross section, and both adjacent protrusions 49 are connected to each other by a connecting piece 49 </ b> A.

  As shown in FIGS. 2 to 4, the shield bracket 5 has a main body 51 covering the mold body 42 substantially along the outer surface of the mold body 42, and an outer surface of the case body 3 in a state of being bolted to the case body 3. And a flange portion 52 projecting along.

  The main body 51 of the shield bracket 5 is formed with a pressure-bonded portion 51A that covers the protruding portion 49 of the mold body 42. As shown in FIG. 2, the shield cable is passed through an opening provided at the end of the pressure-bonded portion 51A. 6 extends to the outside of the shield bracket 5.

  Here, as shown in FIG. 1, the end of the shield body 62 of the shield cable 6 covers the outer peripheral surface of the crimped portion 51 </ b> A at a time, and the caulking ring 7 is crimped from the outer peripheral side of the shield body 62. Thus, the shield body 62 and the shield bracket 5 are connected so as to be conductive. Thereby, the space from the end of the shield cable 6 to the outer surface of the case body 3 is shielded by the shield body 62 and the shield bracket 5.

  The flange portion 52 of the shield bracket 5 has a shallow dish shape, and as shown in FIG. 4, the flange portion 52 has insertion holes 52 </ b> A for bolting formed at a plurality of locations. The shield bracket 5 is fixed to the case body 3 by arranging the insertion hole 52A in accordance with the bolt hole 34 provided on the outer surface of the case body 3 and performing bolting. At this time, since the flange portion 52 is in surface contact with the outer surface of the case body 3, the shield bracket 5 and the case body 3 are connected so as to be conductive.

  Further, since the hole diameter of the insertion hole 52A is larger than the diameter of the bolt inserted into the insertion hole 52A, the position of the shield bracket 5 is finely adjusted in accordance with the position of the mold body 42, and then the case body 3 is adjusted. It can be fixed. For this reason, it is not necessary to provide the alignment structure in the main body 51 of the shield bracket 5, and no gap is formed between the molded connector 4 and the main body 51 of the shield bracket 5, and the shielding performance is not deteriorated.

  A surface of the main body 51 of the shield bracket 5 that faces the mounting surface 48 of the mold body 42 is a pressing surface 51 </ b> B for the seal member 72. The pressing surface 51 </ b> B comes into surface contact with the seal member 72. For this reason, when the shield bracket 5 is attached to the case body 3, the seal member 72 is brought into close contact with both the pressing surface 51 </ b> B and the mounting surface 48, and water may enter the insertion hole 46 from the outside of the case body 3.

  Furthermore, in this embodiment, the assembly direction of the molded connector 4 with respect to the attachment hole 31, the tightening direction of the bolts that fasten the bus bar connection portion 43 of the terminal fitting 41 and the terminal block 33, and the flange portion 52 of the shield bracket 5 The tightening direction of the bolt that bolts the outer surface of the case body 3 and the extending direction of the shielded cable 6 drawn from the molded connector 4 are all set in the same direction. For this reason, when assembling them, it is possible to work from the same direction, and it is possible to work efficiently even if only a narrow work space can be secured.

  The present embodiment is configured as described above. Next, a method for assembling the molded connector 4 to the case body 3 will be described. In the following description, the vertical direction is based on the vertical direction in FIG.

  First, before the molded connector 4 is molded, the shield bracket 5 and the caulking ring 7 are passed through the shield cable 6 side in advance. After the terminal fitting 41 is caulked to the end of the shielded cable 6 and the terminal fitting 41 is molded into the molded body 42 to form the molded connector 4, the fitting portion 47 of the molded body 42 is inserted from above the case body 3. It is inserted into the mounting hole 31 of the case body 3. As a result, the seal member 71 is in close contact with both the outer peripheral surface of the fitting portion 47 and the inner peripheral surface of the mounting hole 31, and the space between the molded connector 4 and the case body 3 is waterproofed.

  With this insertion, the terminal blocks 33 of the three bus bars 32 respectively enter the insertion holes 46, and the through holes 43A of the bus bar connection portion 43 and the through holes 33A of the terminal block 33 are aligned in the vertical direction and are coaxial. Placed in. Accordingly, the terminal tool 41 and the bus bar 32 are inserted by allowing the attachment tool to enter the insertion hole 46 from above the case body 3 and tightening the through hole 43A of the bus bar connection portion 43 and the through hole 33A of the terminal block 33 with the bolts. And are connected so as to be conductive.

  Next, the shield bracket 5 is attached to the molded connector 4 from above the case body 3 along the direction in which the shield cable 6 is pulled out. When the main body 51 of the shield bracket 5 is fitted to the mold body 42 and the flange 52 reaches a position slightly lifted from the upper surface of the case body 3, the pressing surface 51 </ b> B comes into contact with the upper surface of the seal member 72. When the bolt is inserted into the insertion hole 52 </ b> A of the flange portion 52 and tightened into the bolt hole 34, the flange portion 52 comes into contact with the upper surface of the case body 3 and the shield bracket 5 is fixed to the case body 3. As a result, the seal member 72 is in close contact with both the pressing surface 51B and the mounting surface 48, and the space between the shield bracket 5 and the molded connector 4 is waterproofed.

  Next, the end of the shield body 62 of the shield cable 6 is put on the crimped portion 51A of the shield bracket 5, and the caulking ring 7 is crimped from the outside of the shield body 62 so that the shield body 62 can be electrically connected to the shield bracket 5. Connected. On the other hand, since the flange portion 52 of the shield bracket 5 is in contact with the upper surface of the case body 3 and is connected to be conductive, the shield body 62 is connected to the upper surface of the case body 3 through the shield bracket 5 so as to be conductive. . Therefore, it is possible to reliably shield the space from the end of the shield cable 6 to the upper surface of the case body 3.

  As described above, in the present embodiment, a cover for closing the attachment hole 31 and the insertion hole 46 is not required, and the attachment hole 31 and the insertion hole 46 can be closed by attaching the shield bracket 5 to the case body 3. Further, when the shield bracket 5 is attached to the outer surface of the case body 3 after the bus bar connecting portion 43 and the terminal block 33 are bolted, the shield bracket 5 and the molded body are provided between the case body 3 and the shield bracket 5. Since no gap is formed between them, the shielding function is not lowered. Further, since the space between the pressing surface 51B of the shield bracket 5 and the mounting surface 48 of the mold body 42 is sealed by the sealing member 72, a large force is not required when mounting the shield bracket 5, and it can be easily attached. be able to.

<Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to the drawing of FIG. The connection structure 2 between the device and the shielded cable of the present embodiment is different from the first embodiment in that the attachment hole 310 of the case body 30 is directly closed by the shield bracket 50. In the present embodiment, the description of the same configuration as that of the first embodiment is omitted.

  A resin terminal block 330 is provided inside the case body 30. The terminal block 330 is configured to prevent a nut from rotating and to receive a recess portion for receiving a tip portion of a bolt screwed into the nut. Is recessed. Thereby, the through-holes 330A of the three bus bars 320 connected to the device and the through-holes 430A of the bus bar connecting portion 430 of the terminal fitting 410 connected to the core wire 61 of the shielded cable 6 are arranged coaxially. The bus bar 320 and the terminal fitting 410 can be connected by tightening the bolts using, for example.

  The attachment hole 310 of the present embodiment has a larger opening than the first embodiment, and is sized to accommodate the entire bus bar connection portion 430 exposed from the molded connector 40. Further, the bus bar 320 connected to the bus bar connecting portion 430 of the terminal fitting 410 is also routed so as to extend in the horizontal direction (direction intersecting with the assembly direction of the molded connector 40 to the case body 30). For this reason, in the state in which the molded connector 40 and the shield bracket 50 are assembled to the case body 30, the height is significantly reduced as compared with the first embodiment.

  Unlike the first embodiment, the molded body 420 does not include the fitting portion 47 with respect to the mounting hole 31 and is integrated with the cable connection portion 440 of the three terminal fittings 410 and the terminal of the shielded cable 6. The mold body 420 can be fitted into a cylindrical pressure-bonded portion 510 </ b> A provided on the shield bracket 50. A housing groove 421 for housing the annular seal member 73 is provided around the outer peripheral surface of the mold body 420. Thus, the seal member 73 is sandwiched between the outer peripheral surface of the mold body 420 and the inner peripheral surface of the pressed part 510A, so that the space between the shield bracket 50 and the mold body 420 is waterproofed.

  A spacer 74 is attached in advance at a position corresponding to the opening of the attachment hole 310 in the shield bracket 50. The spacer 74 is a member for holding the packing 75 on the shield bracket 50, is made of a resin or metal plate, and is slightly larger than the opening diameter of the mounting hole 310. The spacer 74 is provided with an insertion hole 741 through which the mold body 420 is inserted and a press-fitting hole 742 into which the mounting rib 501 provided in the shield bracket 50 is press-fitted in the thickness direction.

  Since the insertion hole 741 is formed to be slightly larger than the outer shape of the mold body 420, when the shield bracket 50 is attached to the case body 30, the inner peripheral surface of the insertion hole 741 and the outer peripheral surface of the mold body 420 are mutually connected. There is no risk of interference. On the other hand, since the press-fitting hole 742 is formed slightly smaller than the outer shape of the mounting rib 501, the spacer 74 can be fixed to the shield bracket 50 by pushing the press-fitting hole 742 into the mounting rib 501.

  An annular rib 502 is provided around the shield bracket 50 at a position facing the outer peripheral edge of the spacer 74. For this reason, the packing 75 is sandwiched between the outer peripheral edge of the spacer 74 and the annular rib 502. Further, the packing 75 includes a flange portion 751 in which the spacer 74 and the shield bracket 50 enter between the opposing surfaces facing each other. For this reason, when the flange portion 751 is locked to the outer peripheral edge portion of the spacer 74, the packing 75 is restricted from falling off the shield bracket 50.

  The outer peripheral edge of the spacer 74, the inner peripheral surface of the annular rib 502, and the surface of the shield bracket 50 on the case body 30 side constitute an “accommodating groove for accommodating packing” according to the present invention. The “periphery wall of the housing groove for housing the packing” is constituted by the peripheral edge.

  On the other hand, the opening edge 311 in the opening of the attachment hole 310 is a seal surface to which the packing 75 is in close contact. As the shield 75 is fixed to the outer surface of the case body 30, the packing 75 is pressed against the opening edge 311 of the attachment hole 310 and compressed. At this time, since the packing 75 is restricted from being deformed in the radial direction by the outer peripheral edge of the spacer 74 and the inner peripheral surface of the annular rib 502, the surface of the shield bracket 50 on the case body 30 side and the attachment hole 310. It adheres to both of the opening edge portions 311 of the two, and the space between the shield bracket 50 and the case body 30 is waterproof.

  In the present embodiment, as in the first embodiment, the assembly direction of the molded connector 40 with respect to the mounting hole 310, the tightening direction of the bolts that fasten the bus bar connecting portion 430 of the terminal fitting 410 and the bus bar 320, and the shield bracket The tightening direction of the bolt that bolts 50 and the outer surface of the case body 30 and the extending direction of the shielded cable 6 drawn from the molded connector 40 are all set in the same direction. For this reason, when assembling them, it is possible to work from the same direction, and it is possible to work efficiently even if only a narrow work space can be secured.

  The present embodiment is configured as described above. Next, a method for assembling the molded connector 40 to the case body 30 will be described. In the following description, the vertical direction is based on the vertical direction in FIG.

  First, before the molded connector 40 is molded, the shield bracket 50 and the caulking ring 7 are passed through the shield cable 6 side in advance. After the terminal fitting 410 is caulked to the end of the shielded cable 6 and the cable connector 440 of the terminal fitting 410 is molded into the molded body 420 to form the molded connector 40, the bus bar connecting portion 430 is formed from above the case body 30. Is inserted into the mounting hole 310 of the case body 30.

  The through-hole 430A of the bus bar connection part 430 and the through-hole 330A of the bus bar 320 are arranged so as to be coaxially aligned in the vertical direction, and the tool enters the inside of the mounting hole 310 from above the case body 30 to connect the bus bar. By tightening the through hole 430A of the portion 430 and the through hole 330A of the bus bar 320 with a bolt, the terminal fitting 410 and the bus bar 320 are connected in a conductive manner.

  Next, the shield bracket 50 is attached to the molded connector 40 from above the case body 30 along the direction in which the shield cable 6 is pulled out. When the crimped portion 510 </ b> A of the shield bracket 50 is fitted into the mold body 420, the packing 75 comes into contact with the opening edge 311 of the mounting hole 310. When the bolt is inserted into the insertion hole 520 </ b> A and tightened into the bolt hole 340, the shield bracket 50 comes into contact with the upper surface of the case body 30 and is fixed. As a result, the packing 75 is in close contact with both the surface of the shield bracket 50 on the case body 30 side and the opening edge 311 of the attachment hole 310, and the space between the shield bracket 50 and the molded connector 40 is waterproofed.

  Next, the end of the shield body 62 of the shield cable 6 is put on the crimping portion 510A of the shield bracket 50, and the crimping ring 7 is crimped from the outside of the shield body 62 so that the shield body 62 can be electrically connected to the shield bracket 50. Connected. On the other hand, since the shield bracket 50 contacts the upper surface of the case body 30 and is connected to be conductive, the shield body 62 is connected to the upper surface of the case body 30 via the shield bracket 50 so as to be conductive. Therefore, it is possible to reliably shield the space from the end of the shield cable 6 to the upper surface of the case body 30.

  As described above, in this embodiment, a cover for closing the attachment hole 310 is not required, and the attachment hole 310 can be closed by attaching the shield bracket 50 to the case body 30. In addition, when the shield bracket 50 is attached to the outer surface of the case body 30 after the bus bar connection portion 430 and the bus bar 320 are bolted, the space between the case body 30 and the shield bracket 50 and between the shield bracket 50 and the molded body 420 Since no gap is formed between them, the shielding function is not deteriorated. Further, since the space between the shield bracket 50 and the opening edge 311 of the attachment hole 310 is sealed with the packing 75, a large force is not required when the shield bracket 50 is attached, and the shield bracket 50 can be easily attached.
