The vehicle body 202 includes a cooling water circulation device 203 including a heat exchanger and a pump, and a hose 204 connected to the cooling water circulation device 203 is connected to the boss portion 34 of the female assembly 3. The hose 204 may be fastened to the boss portion 34 by a known hose band or the like.

  In the male assembly 5, the male pedestal 81 is bolted to the in-vehicle battery 206 via the spacer 205. The in-vehicle battery 206 includes a water jacket 207, and a hose 208 connected to the water jacket 207 is connected to the boss portion 104 of the male assembly 5. In other embodiments, the hose 208 may be omitted, and the boss 104 may be directly connected to a cooling water passage formed in the water jacket 207 or the in-vehicle battery 206.

  The vehicle body 202 and the in-vehicle battery 206 are connected to each other via connecting devices 209 and 210. The connector device 1 is coupled to the female assembly 3 and the male assembly 5 as the vehicle body 202 and the in-vehicle battery 206 are coupled via the coupling devices 209 and 210. 203 is connected to the water jacket 207 of the in-vehicle battery 206, and cooling water can be exchanged.

  In the process in which the vehicle body 202 and the in-vehicle battery 206 are connected, when the vehicle body 202 and the in-vehicle battery 206 come close to each other, the connector device 1 moves the female connector 20 and the male connector 90 in the axial direction. The tip of the positioning pin 126 of the solid 5 enters the inside of the bottomed cylindrical body 72 of the female side assembly 3. Since the outer diameter of the positioning pin 126 is smaller than the inner diameter of the bottomed cylindrical body 72, even if a manufacturing error of the connector device 1 or an attachment error to the vehicle body 202 or the in-vehicle battery 206 occurs, there is a slight error. Is now allowed.

  Next, when the vehicle body 202 and the in-vehicle battery 206 come closer, the tip of the male second casing 93 of the male connector 90 enters the open end of the female second casing 23 of the female connector 20. At this time, when the axes of the male connector 90 and the female connector 20 are deviated from each other, the peripheral edge of the distal end of the male second casing 93 presses the opening end inner surface 42 of the female second casing 23. Since the opening end inner surface 42 is formed in a conical surface, when the male connector 90 moves in the axial direction with respect to the female connector 20, the female connector 20 moves in the radial direction, and the axial line between the male connector 90 and the female connector 20. Match. That is, the opening end inner surface 42 functions as a guide surface (cam surface), and aligns the female connector 20 and the male connector 90.

  After the axial lines of the male connector 90 and the female connector 20 coincide with each other, the male second casing 93 advances in the small diameter portion 37 of the female second casing 23, and the distal end surface of the male second casing 93 is the female valve. While abutting on the end surface of the body 25, the convex portion 118 of the male valve body 95 is fitted into the connection hole 54 of the female third casing 24. In this state, the outer surface of the male second casing 93 is in sliding contact with the inner surface of the small-diameter portion 37 of the female second casing 23, and the O-ring 114 is in contact with the outer surface of the male second casing 93 and the female second casing. Thus, the female connector 20 and the male connector 90 are connected to each other.

  When the male second casing 93 further advances in the small diameter portion 37 of the female second casing 23, the male second casing 93 resists the biasing force of the female compression coil spring 26 and the female valve body 25. Is pushed into the large-diameter portion 36 to change the female connector 20 to the open state, and the female third casing 24 pushes the male valve element 95 against the urging force of the male compression coil spring 96. 2 Push into the base end side of the casing 93 to change the male connector 90 to the open state, and fluid flow between the female connector 20 and the male connector 90 becomes possible.

  In the connector device 1 according to the present embodiment, when the vehicle body 202 and the in-vehicle battery 206 are connected, the female connector 20 is displaced with respect to the female pedestal 11 even if the axes of the female connector 20 and the male connector 90 are shifted from each other. Then, the axes of the female connector 20 and the male connector 90 can be made to coincide with each other. Therefore, the female connector 20 and the male connector 90 can be reliably connected even if there is an error in attaching the female assembly 3 and the male assembly 5 to the vehicle body 202 or the in-vehicle battery 206. That is, the attachment of the female assembly 3 and the male assembly 5 to the vehicle body 202 or the in-vehicle battery 206 is not required to be highly accurate, and the attachment workability can be improved. Further, when a plurality of female connectors 20 are provided for the female side pedestal 11, the connection between one female connector 20 and the corresponding male connector 90 is the connection between the other female connector 20 and the corresponding male connector 90. There is no hindrance.

The boot 64 is reduced in diameter at a portion corresponding to the opening end of the small diameter portion 37, and an inner surface thereof forms a protruding portion 301 that protrudes onto the opening end surface of the small diameter portion 37. On the distal end side of the boot 64 of the overhang portion 301, a guide portion 303 having a conical guide surface 302 that gradually increases in diameter as it proceeds toward the distal end side is formed on the inner surface. A bellows portion 304 that can be expanded and contracted in the axial direction of the boot 64 is formed on the distal end side of the boot 64 of the guide portion 303. The guide portion 303 is formed thicker than the bellows portion 304 and is not easily deformed.

  In the second embodiment, the guide surface 302 of the boot 64 aligns the female connector 20 and the male connector 90 instead of the opening end inner surface 42 of the small diameter portion 37 in the first embodiment. That is, when the male connector 90 and the female connector 20 are connected, the peripheral edge portion of the male second casing 93 slides on the guide surface 302 of the boot 64 to move the female connector 20 in the radial direction. The axes of the connectors 20 and 90 are coaxial.

(Third embodiment)
Compared with the connector device 1 according to the first embodiment, the connector device 400 according to the third embodiment has a female valve body 25, a female third casing 24, a male second casing 93, and a male valve body 95.

The side corresponding to the opening end side of the small-diameter portion 37 of the female-side valve body 25 includes an extension portion 402 that protrudes toward the opening end side of the small-diameter portion 37 from the tip portion 49 of the female-side third casing 24. A taper surface 403 is formed on the extension 402 so as to form one continuous concave conical surface in cooperation with the connection hole 401.

  One end of the small tube portion 116 of the male valve body 95 in the connector device 400 is closed by a conical convex portion 405 that can be fitted into the connection hole 401 of the female third casing 24. The convex portion 405 protrudes from the distal end portion of the cylindrical portion 106 of the male second casing 93, and the distal end portion of the cylindrical portion 106 forms one continuous convex conical surface in cooperation with the convex portion 405. Thus, a tapered surface 406 is formed. A continuous conical convex portion 408 formed by the convex portion 405 and the tapered surface 406 can be fitted into a continuous conical concave portion 409 formed by the connecting hole 401 and the tapered surface 403.

  As described above, in the connector device 400, the male connector 90 itself functions as a positioning pin because the relatively large conical convex portion 408 formed by the convex portion 405 and the tapered surface 406 is provided at the tip of the male connector 90. Then, the female connector 20 and the male connector 90 can be aligned by slidingly contacting the opening end inner surface 42 of the female second casing 23 at the convex portion 405. With this configuration, the positioning pin 126 and the bottomed cylindrical body 72 can be omitted.

(Fourth embodiment)

It is supported by the side pedestal 11. Since the other structure of the connector apparatus 500 is the same structure as the connector apparatus 1, the same code | symbol as the connector apparatus 1 is attached | subjected and description is abbreviate | omitted.

  As shown in FIGS. 11 and 12, the intermediate pedestal 501 supports the two female connectors 20 so as to be independently displaceable. On the lower surface of the intermediate pedestal 501, two bottomed intermediate pedestal holes 502 into which the base 32 of the female first casing 22 of the female connector 20 can be loosely fitted are formed. The intermediate pedestal hole 502 is formed larger than the diameter of the base 32, and the base 32 can be displaced in the direction perpendicular to the axis of the female connector 20 within the intermediate pedestal hole 502. In addition, a through hole 503 that penetrates to the upper surface side of the intermediate base 501 and through which the boss 34 of the female first casing 22 is inserted is formed at the bottom of each intermediate base hole 502. The diameter of the through hole 503 is such that the boss of the female first casing 22 does not contact the through hole 503 even if the female connector 20 is displaced within the intermediate seat hole 502. It is formed sufficiently larger than the outer diameter of the portion 34.

  A bottomed intermediate base support hole 505 into which the intermediate base 501 can be loosely fitted is formed on the lower surface of the female side base 11. A portion of the bottom of the intermediate pedestal support hole 505 corresponding to the two through holes 503 of the received intermediate pedestal 501 penetrates to the upper surface side of the female side pedestal 11 and is supported by the intermediate pedestal 501. Two through holes 506 are formed through which the bosses 34 of the female first casing 22 of the connector 20 are inserted. The through hole 506 of the female side pedestal 11 prevents the boss portion 34 from coming into contact with the through hole 506 even if the female connector 20 is displaced in the intermediate pedestal 501 and the intermediate pedestal 501 is displaced in the intermediate pedestal support hole 505.
