A floating structure is also constructed.

In the interlock circuit 60 of the present embodiment, as shown in FIG. 8, the interlock connector 65 provided in the housing 10, the connector-side detection connector 70 provided in the connector 20, and the cover 50 are provided. The provided cover-side detection connector 90 is arranged side by side on a vertical straight line VL along the fitting direction of the connector 20.
Further, as shown in FIG. 10, the first detection switch 61 is constituted by the cover side detection connector 90 and the connector side detection connector 70, and the second detection switch 62 is constituted by the connector side detection connector 70 and the interlock connector 65, respectively. Has been.

Then, the effect | action of this embodiment is demonstrated.
The connector device C is assembled in the following procedure. The connector 20 and the three-pole connector 20X formed as described above are attached to the connector attachment portions 12 and 12X provided in the casing 10, respectively.
Specifically, on the connector 20 side, as shown in FIG. 10, the fitting portion 31 provided in the connector 20 is fitted into the connector mounting portion 12 of the housing 10. Accordingly, the housing 75 (tower portion 77) of the connector side detection connector 70 is fitted with the housing 66 of the interlock connector 65 provided in the housing 10. At this time, if the tower portion 77 and the housing 66 of the interlock connector 65 are misaligned, the housing 75 of the connector-side detection connector 70 moves on the horizontal plane in the support portion 84 and is fitted while being aligned. The When the fitting is completed, the lower female terminal 73A in the relay terminal 71 and the corresponding male terminal 67 are connected, and the second detection switch 62 in the interlock circuit 60 is closed. However, since the first detection switch 61 remains open, the interlock circuit 60 is in an off state.

  At this time, as shown in FIG. 10, the lower end of the metal sleeve 35 inserted into the sleeve insertion part 36 of the fitting part 31 is arranged on the upper surface of the device side terminal 17 in the housing 10. The connection bolt 19 is inserted into the metal sleeve 35 from the opening 33 of the housing 30 and fastened to the nut 18. As a result, the bus bar terminal 22 is sandwiched between the head 19 </ b> A of the connection bolt 19 and the upper end surface of the metal sleeve 35, and the device side terminal 17 is sandwiched between the lower end surface of the metal sleeve 35 and the nut 18. Thus, the bus bar terminal 22 and the device side terminal 17 are connected to each other through the metal sleeve 35 so as to be conductive, and a conduction path for power feeding is formed.

  When the connector 20 and the three-pole connector 20X are attached, the cover 50 is attached so as to cover both the connectors 20 and 20X. The cover 50 is covered with the closing portions 52 and 52X fitted to the openings 33 and 33X of the connectors 20 and 20X, and through the mounting bolts 55 through the four insertion holes 56 provided in the cover-side shield shell 51, By screwing it into the screw hole 15 of the support column 14 with the side shield shells 40, 40X interposed therebetween, it is fixed to the housing 10 and the assembly of the connector device C is completed (see FIG. 9).

  During the attaching operation of the cover 50 described above, on the connector 20 side, the terminal accommodating portion 96 of the housing 95 of the cover side detection connector 90 is fitted into the hood portion 79 of the housing 75 of the connector side detection connector 70. . At this time, if the terminal accommodating portion 96 and the hood portion 79 are misaligned, the housing 95 of the cover side detection connector 90 moves on the horizontal plane along the back surface of the cover side shield shell 51 and is centered. Mated. When the fitting is completed, as shown in FIGS. 10 and 11, the upper connection portion of the male terminal 74 in the female terminal 91 arranged in the cover side detection connector 90 and the relay terminal 71 arranged in the connector side detection connector 70. 74B is connected, and the first detection switch 61 in the interlock circuit 60 is also closed. As a result, the interlock circuit 60 is turned on, and the conduction path can be energized.

  When removing the connector 20 (20X) from the housing 10 for maintenance or the like, from the state shown in FIG. 9, first, the four mounting bolts 55 are loosened, and the closing portion 52 (52X) is opened to the connector 20 (20X). The cover 50 is removed upward while being pulled out from the portion 33 (33X). Accordingly, the terminal accommodating portion 96 of the housing 95 of the cover-side detection connector 90 is detached from the hood portion 79 of the housing 75 of the connector-side detection connector 70, and the female terminals 91 disposed on the cover-side detection connector 90 and the connector The connection with the upper connection part 74B of the male terminal 74 in the relay terminal 71 arranged in the side detection connector 70 is released. Thereby, the 1st detection switch 61 opens and the interlock circuit 60 will be in an OFF state.

Next, a tool such as a wrench is inserted through the opening 33 of the housing 30 of the connector 20 to loosen the connection bolt 19. The connection bolt 19 constitutes a part of the conduction path for power supply. However, since the interlock circuit 60 is turned off and the conduction to the conduction path is interrupted as described above, the connection bolt 19 is The work of loosening is performed without any problem.
When the connection bolt 19 is removed from at least the nut 18, the connector 20 is removed upward while removing the fitting portion 31 from the connector mounting portion 12 of the housing 10. Accordingly, the tower portion 77 of the housing 75 of the connector side detection connector 70 is detached from the housing 66 of the interlock connector 65 fixed in the housing 10, and the relay terminal 71 arranged on the connector side detection connector 70. The connection between the lower female terminal 73A and the male terminal 67 disposed on the interlock connector 65 is released, and the second detection switch 62 is also opened.

  After the maintenance is completed, the connector device C is assembled again in the manner described above. In the case of reassembly, for example, the state in which the cover 50 is attached to the housing 10 without the connector 20 attached may appear on the structure. In this case, the device side terminal 17 which is a part of the conductive path is exposed to the outside through the connector mounting portion 12. However, in the interlock circuit 60, the interlock connector 65 and the cover side detection connector 90 are provided. Are conceptually separated from each other, conceptually both the first detection switch 61 and the second detection switch 62 are open, and the interlock circuit 60 is in an OFF state. It is in a blocked state.

  As described above, according to the present embodiment, the first detection switch 61 that detects attachment / detachment of the cover 50 by the cover side detection connector 90 provided on the cover 50 and the connector side detection connector 70 provided on the connector 20. However, the connector-side detection connector 70 and the interlock connector 65 provided in the housing 10 constitute a second detection switch 62 that detects the attachment / detachment of the connector 20. Interlock circuit 60 is constructed with detection switches 61 and 62 respectively at two places with a gap, that is, two places where a part of the conductive path may be exposed. Here, since both the detection switches 61 and 62 are arranged on a straight line along the fitting direction of the connector 20, the structure can be simplified and the entire apparatus can be reduced in size.

  Since the cover side detection connector 90 is supported by the cover 50 and the connector side detection connector 70 is supported by the connector 20 in a so-called floating structure, the female terminals 91 ( Even if there is a misalignment between the cover side detection terminal), the relay terminal 71 provided on the connector side detection connector 70, and the male terminal 67 (device side detection terminal) provided on the interlock connector 65, it is floating. The terminals 91, 71, and 67 can be connected in a state of being accurately aligned in a line while absorbing misalignment using the structure.
