Summary of Invention

Problem to be Solved by the Invention

[0004] By the way, in connectors such as that described in Patent Document 1, along with the increase in capacity of power sources due to improvements in the cruising range of vehicles and the like, application of bus bars instead of electric wires to allow large currents to flow has been studied. Bus bars have high rigidity, and it is difficult to arrange a single bus bar while bending it inside the housing. For this reason, the bus bar is configured to have a first bus bar accommodated in the housing, and a second bus bar that is electrically connected to the first bus bar via a connection portion and drawn out of the housing from the lead-out portion. The arrangement position of the second bus bar at the lead-out portion may fluctuate due to assembly errors at the connection portion. Therefore, it is necessary to provide a gap between the lead-out portion and the second bus bar to absorb the assembly errors.

[0005] In this connector, a proximity probe is used to detect whether a thin metal component, such as a wire, could be inserted from the lead-out portion into the housing and come into contact with a conductive part such as the first busbar or connection portion. However, if a gap is formed between the lead-out portion and the second busbar, the proximity probe could be inserted into the housing through the gap and come into contact with the conductive part.

[0006] This invention has been made in view of the problems of the prior art. The object of this invention is to provide a connector that can suppress contact of the proximity probe to the conductive portion at the lead-out section. [Means for solving the problem]

[0007] The connector according to this embodiment comprises a housing and a busbar housed in the housing, wherein the housing is provided with a pull-out section from which the busbar is pulled out to the outside, and the busbar has a first busbar housed in the housing and a second busbar electrically connected to the first busbar via a connection section and pulled out to the outside of the housing from the pull-out section, a gap is provided between the pull-out section and the second busbar that can absorb assembly errors at the connection section, and the pull-out section is provided with a wall section that protrudes outward from the opening edge of the pull-out section along the pulling direction of the second busbar and extends along the outer surface of the second busbar. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a connector that can suppress contact of the proximity probe with the conductive portion in the lead-out section. [Brief explanation of the drawing]

[Figure 10] This is a perspective view of the connector cover according to this embodiment. [Modes for carrying out the invention]

[0010] The connector according to this embodiment will be described in detail below with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0011] As shown in Figure 1, the connector 1 according to this embodiment is applied to a vehicle charging unit for charging a power supply (not shown) mounted on a vehicle (not shown), such as an electric vehicle or a hybrid vehicle. The connector 1 is matable with a charging connector (not shown) electrically connected to a charging device (not shown) located, for example, on a charging station. By mating the charging connector with the connector 1, power is supplied from the charging device to the power supply, and the power supply is charged. Power supplies are increasingly becoming high-capacity in order to improve the driving range of vehicles. High-capacity power supplies have long charging times, so by using a busbar 9 (see Figure 2) with a large cross-sectional area instead of wires, a large current can be carried, and the charging time can be shortened.

[0012] As shown in Figures 1 to 10, the connector 1 comprises an outer housing 3, an inner housing 5, terminals 7, busbars 9, a housing 11, and a cover 13.

[0013] As shown in Figures 1 to 4, the outer housing 3 is made of an insulating material such as synthetic resin. The outer housing 3 is located on the outermost side of the vehicle's charging section and is formed in a rectangular housing shape. The outer housing 3 is provided with a plurality (four in this case) of vehicle fixing parts 15 that are fixed to the vehicle body (not shown) via fixing members (not shown) such as bolts. In the center of the outer housing 3, a mating opening 17 into which a charging connector is fitted is formed, penetrating the outer housing 3.

[0014] As shown in Figures 1 to 4, the inner housing 5 is made of an insulating material such as synthetic resin. The inner housing 5 is formed in a housing shape that can accommodate a plurality (seven in this case) of terminals 7 inside and can be mated with a charging connector. The inner housing 5 is provided with a plurality of inner fixing parts 19 that are fixed to the outer housing 3 via screw members. The inner housing 5 is provided with a mating part 21 that extends in a cylindrical shape toward the direction of mating with the charging connector. The mating part 21 is positioned in the mating opening 17 of the outer housing 3. The outer surface of the mating part 21 is provided with a locking part 23 that maintains the mated state with the charging connector. The mating part 21 includes a normal mating part 25 and a rapid mating part 27.

[0015] The normal fitting portion 25 is arranged above the fitting portion 21. The normal fitting portion 25 is capable of fitting with a normal charging connector (not shown) among charging connectors that can charge a power source in a normal time. Inside the normal fitting portion 25, a plurality (five in this case) of normal terminal accommodating chambers 29 are formed. A terminal for normal charging (not shown) is accommodated in the normal terminal accommodating chamber 29. The terminal for normal charging includes, for example, a power terminal for power supply, a communication terminal for detecting a charging state, and the like. The terminal for normal charging is electrically connected to an end portion of an electric wire (not shown) electrically connected to a power source. The terminal for normal charging accommodated in the normal terminal accommodating chamber 29 is held in the normal terminal accommodating chamber 29 by a holder (not shown) assembled on the side opposite to the fitting opening 17 with respect to the inner housing 5. When the normal charging connector is fitted to the normal fitting portion 25, the counterpart terminal of the normal charging connector and the terminal for normal charging are electrically connected. By the electrical connection between the terminal for normal charging and the counterpart terminal, the power source can be charged from the charging facility in a normal time.

[0016] The quick fitting portion 27 is arranged below the fitting portion 21. The quick fitting portion 27 is capable of fitting with a quick charging connector (not shown) among charging connectors that can charge a power source in a short time. Inside the quick fitting portion 27, a plurality (two in this case) of quick terminal accommodating chambers 31 are formed. A terminal 7 for quick charging is accommodated in the quick terminal accommodating chamber 31. The terminal 7 for quick charging is, for example, a power terminal for power supply. The terminal 7 for quick charging is electrically connected to a bus bar 9 electrically connected to a power source. The terminal 7 for quick charging accommodated in the quick terminal accommodating chamber 31 is held in the quick terminal accommodating chamber 31 by a housing 11 that holds the bus bar 9 assembled on the side opposite to the fitting opening 17 with respect to the outer housing 3. When the quick charging connector is fitted to the quick fitting portion 27, the counterpart terminal of the quick charging connector and the terminal 7 for quick charging are electrically connected. By the electrical connection between the terminal 7 for quick charging and the counterpart terminal, the power source can be charged from the charging facility in a short time.

[0017] As shown in Figure 1, Figure 4 and Figure 6, the terminal 7 is made of a conductive material such as a metal material, for example. The terminal 7 is, for example, a power supply terminal, and a plurality of them (two in this case) are used. The terminal 7 is formed in a cylindrical shape extending along the fitting direction between the connector 1 and the charging connector. One end side of the terminal 7 serves as an electrical connection portion 33. The electrical connection portion 33 is arranged on the side of the fitting opening 17 in a state where the terminal 7 is disposed in the quick terminal accommodating chamber 31. The electrical connection portion 33 is electrically connected to the mating terminal of the charging connector when the connector 1 and the charging connector are fitted to each other. The other end side of the terminal 7 serves as a bus bar connection portion 35. The bus bar connection portion 35 is formed in a hollow shape, and a thread groove is formed on the inner peripheral surface thereof. The bus bar connection portion 35 is electrically connected to the bus bar 9 by fastening a bolt 37 thereto.

[0018] As shown in Figure 2 to Figure 8, the bus bar 9 is formed by processing a conductive material such as a metal material into a plate shape, for example. A plurality of bus bars 9 (two sets in this case) are used corresponding to the plurality of terminals 7. The bus bar 9 includes a first bus bar 39 and a second bus bar 41.

[0019] The first bus bar 39 is formed in an L shape, for example. At both end sides of the first bus bar 39, first through holes 43 respectively penetrating the first bus bar 39 in the thickness direction are formed. One of the first through holes 43 is formed in a perfect circular shape, and the other first through hole 43 is formed in an oblong shape. Adjacent first bus bars 39, 39 are arranged in a symmetrical shape. A bolt 37 to be fastened to the bus bar connection portion 35 of the terminal 7 is inserted through one first through hole 43 of the first bus bar 39, and by fastening the bolt 37 to the bus bar connection portion 35, the first bus bar 39 and the terminal 7 are electrically connected. When the first through hole 43 through which the bolt 37 is inserted is oblong, the arrangement position of the first bus bar 39 relative to the terminal 7 can be adjusted, and assembly errors can be absorbed. A bolt 45 for electrically connecting the first bus bar 39 and the second bus bar 41 is inserted through the other first through hole 43 of the first bus bar 39.

[0020] The second busbar 41 is formed, for example, in a straight line. The outer surface of the second busbar 41 is covered with an insulating coating 47. A second through-hole 49 is formed at one end of the second busbar 41, penetrating the second busbar 41 in the thickness direction. The second through-hole 49 is formed in an oval shape. A bolt 45 is inserted through the second through-hole 49 with the first through-hole 43 and the second through-hole 49 of the first busbar 39 superimposed, and fastened to a nut 51. By fastening the bolt 45 to the nut 51, the first busbar 39 and the second busbar 41 are electrically connected. The first through-hole 43, the bolt 45, the second through-hole 49, and the nut 51 that electrically connect the first busbar 39 and the second busbar 41 constitute a connection portion 53. By forming the second through-hole 49 through which the bolt 45 is inserted in an oval shape, the position of the second busbar 41 relative to the first busbar 39 can be varied, and assembly errors can be absorbed. The other end of the second busbar 41 is electrically connected to the power supply, and terminal 7 and the power supply are electrically connected via busbar 9. By using busbar 9 as the conductive member that supplies power to the power supply, a large current can be carried, and it is possible to accommodate a larger power supply capacity.

[0021] As shown in Figures 1 to 5 and Figure 9, the housing 11 is made of an insulating material such as synthetic resin. The housing 11 is formed in a housing shape capable of accommodating the busbar 9. The housing 11 is positioned on the side of the rapid-fitting portion 27 of the inner housing 5, opposite to the fitting opening 17 of the outer housing 3. The housing 11 is provided with a plurality (four in this case) of outer fixing portions 55 that are fixed to the outer housing 3 via screw members. The housing 11 includes a terminal housing portion 57 and a busbar housing portion 59.

[0022] The terminal housing section 57 is formed in a cylindrical shape that extends along the mating direction between the connector 1 and the charging connector, so as to be able to accommodate the busbar connection section 35 of the terminal 7. Multiple terminal housing sections 57 are provided to accommodate multiple terminals 7 (two in this case). The busbar connection section 35 of the terminal 7 is positioned in the terminal housing section 57, and the electrical connection section 33 of the terminal 7 is exposed to the outside toward the inner housing 5.

[0023] The busbar housing 59 has an opening 61 on the side opposite to the inner housing 5, and is formed to have a bottom wall and side walls capable of supporting the first busbar 39. The interior of the busbar housing 59 is divided into multiple sections (two in this case) by the side walls to correspond to multiple busbars 9. The opening 61 of the busbar housing 59 is large enough to insert the first busbar 39 and exposes the connection portion 53 of the busbar 9. The bottom wall of the busbar housing 59 is in communication with the terminal housing 57 in the portion where the terminal housing 57 is located. The side wall of the busbar housing 59 is provided with a pull-out section 63 that is open to allow the second busbar 41 to be pulled out to the outside of the housing 11. Multiple pull-out sections 63 are provided to correspond to multiple second busbars 41 (two in this case). The width of the pull-out section 63 is set wider than the width of the second busbar 41. Therefore, a gap is formed between the pull-out section 63 and the second busbar 41, allowing the second busbar 41 to move on both sides in the width direction, and absorbing assembly errors at the connection section 53 of the busbar 9. The first busbar 39, with the terminal 7 assembled, is housed in the busbar housing section 59 through the opening 61, so that the terminal 7 is housed in the terminal housing section 57. The second busbar 41 is electrically connected to the first busbar 39 housed in the busbar housing section 59 by fastening bolts 45 at the connection section 53, and the second busbar 41 is pulled out from the pull-out section 63 to the outside of the housing 11. Multiple (two in this case) fixing sections 65 are provided on the outer surface of the busbar housing section 59, which are formed in a flange shape and have holes with screw grooves on their inner surfaces. The cover 13 is attached to the fixing sections 65 via bolts 67, closing the opening 61 of the busbar housing section 59.

[0024] As shown in Figures 1 to 5 and Figure 10, the cover 13 is made of an insulating material such as synthetic resin. The cover 13 is formed in a housing shape that can close the opening 61 of the housing 11. The size of the cover 13 is set so that its side walls are positioned on the outer surface of the side walls of the busbar housing portion 59 of the housing 11. The cover 13 is provided with a plurality of cover fixing portions 69 (two in this case) which are formed in a flange shape and have holes through which bolts 67 can be inserted, at positions corresponding to the fixing portion 65 of the housing 11. The cover 13 is fixed to the housing 11 by inserting the bolts 67 through the cover fixing portions 69 and fastening the bolts 67 to the fixing portion 65. The cover 13 is provided with a plurality of cover pull-out portions 71 (two in this case) which are open to allow the second busbar 41 to be pulled out to the outside of the housing 11, at positions corresponding to a plurality of pull-out portions 63 of the housing 11. The width of the cover extension 71 is equal to the width of the extension 63 and is set wider than the width of the second busbar 41. As a result, a gap is formed between the cover extension 71 and the second busbar 41, allowing the second busbar 41 to move on both sides in the width direction, and absorbing assembly errors at the connection portion 53 of the busbar 9. The cover 13 is positioned to close the opening 61 of the housing 11 when the busbar 9 is housed in the housing 11. The cover 13, which closes the opening 61, is held in place by the housing 11 by fastening bolts 67 to the cover fixing portion 69. By closing the opening 61 of the housing 11 with the cover 13, the connection portion 53 can be adjusted by removing the cover 13 while the busbar 9 is housed in the housing 11, thereby improving the design flexibility of the busbar 9.

[0025] In connector 1, the proximity probe 73 detects whether a thin metal member, such as a wire, could be inserted into the housing 11 from the lead-out portion 63 and come into contact with a conductive part such as the first busbar 39 or the connection portion 53. The proximity probe 73 has a detection portion 75 made of metal, a spherical portion 77 made of insulating material, and a gripping portion 79 made of insulating material. The proximity probe 73 grips the gripping portion 79, inserts the detection portion 75 into a symmetrical gap, and detects whether the detection portion 75 could come into contact with a conductive part. The spherical portion 77 of the proximity probe 73 serves as a stopping surface for the symmetrical gap. A gap is formed between the lead-out portion 63 and the second busbar 41 to absorb assembly errors in the connection portion 53 of the busbar 9. When a gap is formed between the lead-out portion 63 and the second busbar 41, the detection portion 75 of the proximity probe 73 could be inserted into the housing 11 through the gap and come into contact with a conductive part. Therefore, the drawer section 63 (cover drawer section 71) is provided with a wall section 81 (cover wall section 83).

[0026] The wall portion 81 protrudes outward from the opening edge located below the drawer portion 63 along the drawer direction of the second busbar 41 as a single continuous member with the housing 11, and extends along the outer surface (bottom surface) of the second busbar 41 in the width direction of the second busbar 41. Multiple (three in this case) reinforcing ribs, formed from a single continuous member with the housing 11, are provided on the bottom surface of the wall portion 81 to maintain the rigidity of the wall portion 81. The width of the wall portion 81 is wider than the width of the second busbar 41 and is set to be located at the opening edges on both sides in the width direction of the drawer portion 63. Therefore, within the drawer portion 63, the wall portion 81 is positioned overlapping below the second busbar 41 even when the second busbar 41 is moved to one side in the width direction due to assembly errors of the connection portion 53. The wall portion 81 comes into contact with the tip of the detection portion 75 of the proximity probe 73 when the tip of the detection portion 75 of the proximity probe 73 approaches the opening of the extension portion 63 while sliding on the outer surface of the housing 11. Therefore, the detection portion 75 of the proximity probe 73 is not inserted into the gap between the extension portion 63 and the second busbar 41, and contact between the detection portion 75 of the proximity probe 73 and conductive parts such as the first busbar 39 and the connection portion 53 can be suppressed.

[0027] Here, as shown in Figure 4, when attempting to insert the detection unit 75 of the proximity probe 73 into the gap of the pull-out unit 63, the spherical unit 77 interferes with the second busbar 41, making it impossible to insert it from a direction parallel to the pull-out direction of the second busbar 41. That is, for example, if the operator is holding a thin metal tool such as a wire, the operator's hand interferes with the second busbar 41, making it very difficult to insert the tool into the gap of the pull-out unit 63 from a direction parallel to the pull-out direction of the second busbar 41. For this reason, the detection unit 75 inserted into the gap of the pull-out unit 63 is inserted into the housing 11 in an inclined state while contacting (sliding) with the protruding end of the wall unit 81. For example, if the protruding length L of the wall unit 81 from the opening edge of the pull-out unit 63 is short, the detection unit 75 may be inserted into the gap of the pull-out unit 63 near the opening edge of the pull-out unit 63 and come into contact with the first busbar 39.

[0028] Therefore, the protrusion length L of the wall portion 81 from the opening edge of the pull-out portion 63 is set to a length such that the detection portion 75 of the proximity probe 73 does not come into contact with the first busbar 39 when the detection portion 75 of the proximity probe 73 is inserted into the gap between the pull-out portion 63 and the second busbar 41 while abutting against the protruding end of the wall portion 81. With the wall portion 81 set to an appropriate protrusion length L, when the detection portion 75 abuts (slides) against the protruding end of the wall portion 81, it is inserted into the gap of the pull-out portion 63 while being guided upward so as to avoid the first busbar 39. For this reason, even when the detection portion 75 is inserted into the gap of the pull-out portion 63, contact between the detection portion 75 and the protruding end of the wall portion 81 can be prevented from occurring between the detection portion 75 and the first busbar 39.

[0029] Here, the pull-out section 63 from which the second busbar 41 is pulled out can also be formed by providing a rectangular through-hole in the side wall of the housing 11. In a rectangular pull-out section 63, the first busbar 39 and the second busbar 41 can be electrically connected via the connection section 53 from the opening 61 by inserting the second busbar 41 into the pull-out section 63 from outside the housing 11. For such a pull-out section 63, a wall section 81 can be provided along the entire opening edge of the pull-out section 63. In this embodiment, the upper part of the pull-out section 63 of the housing 11 is open, and the upper opening of the pull-out section 63 is closed by the cover pull-out section 71 of the cover 13. Therefore, the cover pull-out section 71 is provided with a cover wall section 83.

[0030] The cover wall portion 83 is a single continuous member with the cover 13, projecting outward from the opening edges located above and on both sides of the cover extension portion 71 along the extension direction of the second busbar 41. The cover wall portion 83 extends along the width and thickness directions of the second busbar 41, along the outer surface (top surface and both sides) of the second busbar 41. The width of the upper cover wall portion 83 is wider than the width of the second busbar 41 and is set to be located at the opening edges on both sides in the width direction of the cover extension portion 71. Therefore, within the cover extension portion 71, the upper cover wall portion 83 is positioned overlapping the second busbar 41 even when the second busbar 41 is moved to one side in the width direction due to assembly errors of the connection portion 53. The width (height) of the cover wall portions 83 on both sides is set to be wider (higher) than the thickness of the second busbar 41. Therefore, the cover wall portions 83 on both sides are positioned overlapping the sides of the second busbar 41. The cover wall portion 83 comes into contact with the tip of the detection portion 75 of the proximity probe 73 when the tip of the detection portion 75 of the proximity probe 73 approaches the opening of the cover extension portion 71 while sliding along the outer surface of the cover 13. Therefore, the detection portion 75 of the proximity probe 73 is not inserted into the gap between the cover extension portion 71 and the second busbar 41, and contact between the detection portion 75 of the proximity probe 73 and conductive parts such as the first busbar 39 and the connection portion 53 can be suppressed.

[0031] Such a connector 1 comprises a housing 11 and a busbar 9 housed within the housing 11. The housing 11 is also provided with a lead-out section 63 through which the busbar 9 is extended to the outside. The busbar 9 has a first busbar 39 housed within the housing 11 and a second busbar 41 that is electrically connected to the first busbar 39 via a connection section 53 and extends from the lead-out section 63 to the outside of the housing 11. A gap is provided between the lead-out section 63 and the second busbar 41 to absorb assembly errors in the connection section 53. The lead-out section 63 is provided with a wall section 81 that protrudes outward from the opening edge of the lead-out section 63 along the direction in which the second busbar 41 is extended and extends along the outer surface of the second busbar 41.

[0032] The wall portion 81 comes into contact with the tip of the detection portion 75 of the proximity probe 73 when the tip of the detection portion 75 of the proximity probe 73 approaches the opening of the extension portion 63 while sliding on the outer surface of the housing 11. Therefore, the detection portion 75 of the proximity probe 73 is not inserted into the gap between the extension portion 63 and the second busbar 41, and contact between the detection portion 75 of the proximity probe 73 and conductive parts such as the first busbar 39 and the connection portion 53 can be suppressed.

[0033] Therefore, with such a connector 1, contact of the proximity probe 73 with the conductive portion of the lead-out section 63 can be suppressed.

[0034] Furthermore, the protruding length L of the pull-out portion 63 of the wall portion 81 from the opening edge is set to a length such that the detection portion 75 of the proximity probe 73 does not come into contact with the first busbar 39 when the detection portion 75 of the proximity probe 73 is inserted into the gap between the pull-out portion 63 and the second busbar 41 while in contact with the protruding end of the wall portion 81.

[0035] Therefore, even if the detection unit 75 is inserted into the gap of the pull-out section 63, contact between the detection unit 75 and the protruding end of the wall section 81 can be prevented from contacting the detection unit 75 and the first busbar 39.

[0036] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment.

[0037] For example, while the housing contains two busbars, it is not limited to this; the housing can contain one, three or more busbars, and the number of busbars should be set according to the number of terminals.

[0038] Furthermore, while the busbar is composed of a first busbar and a second busbar, it is not limited to this configuration. For example, the first busbar housed inside the housing may be composed of two or more busbars.

[0039] Furthermore, while the cover is provided with a cover pull-out section, the design is not limited to this. The pull-out section of the housing may be formed by a through-hole that is continuous in the circumferential direction, and the cover may be designed to close the opening of the housing without providing a cover pull-out section.

[0040] Furthermore, although the housing is positioned on the quick-fitting side of the inner housing, it is not limited to this arrangement; the housing may also be positioned on the normal-fitting side of the inner housing. [Explanation of Symbols]
