Description

  The present invention relates to a coupler, a socket, a plug, a hose with a socket, a hose with a plug, piping with a socket, piping with a plug, a cooling plate module, an electronic module, an electronic unit, and an electronic device.

2. Description of the Related Art Conventionally, there is a coupler that includes a socket having a valve that opens and closes a flow path through which liquid flows, and a plug that has a valve that opens and closes a flow path through which liquid flows.
In such a coupler, when the socket and the plug are coupled, the valve provided in the socket flow path and the valve provided in the plug flow path are pressed against each other so that the socket flow path and the plug flow path are And the liquid flows from one channel of the socket and the plug to the other channel. On the other hand, when the socket and plug are removed, the socket flow path is closed by the socket valve, and the plug flow path is closed by the plug valve so that liquid does not flow out of the socket and plug flow paths. It has become.

  However, when removing the socket and the plug, the valve provided in the socket flow path moves in the direction of closing the socket flow path, and the valve provided in the plug flow path in the direction of closing the plug flow path. Move. As a result, the liquid that has entered the space of the movable range of each valve is pushed out and leaks outward. Although there is a so-called zero spill coupler, liquid leakage is unavoidable.

  Therefore, a coupler has been proposed in which liquid leaking from the socket or plug is absorbed by an elastic water-absorbing member attached to the outer periphery of the socket and plug so that liquid leakage during removal can be prevented (for example, Patent Document 1).

By the way, when removing the socket and plug of the coupler, there is a case where liquid is not allowed to leak around.
For example, when an electronic component or a circuit board exists around a coupler as in an electronic device such as a water-cooled server, liquid is not allowed to leak around the coupler. That is, in an electronic device such as a water-cooled server, a coupler is used so that a cooling plate can be attached and detached during maintenance, parts replacement, and the like. The coupler socket and plug are removed in the housing. When the coupler socket and plug are removed, electronic components and circuit boards are present around the coupler socket and plug, so that liquid cannot be allowed to leak around. In addition, for example, even when a dangerous substance is contained in the liquid flowing through the flow path connected using the coupler, the liquid is not allowed to leak around.

  For example, in the coupler described in Patent Document 1, since the liquid leaking from the socket and the plug is absorbed by the elastic water absorbing member attached to the outer periphery of the socket and the plug, depending on the removing operation, There is a risk of liquid leaking around. For example, if the socket and the plug are separated before the liquid is absorbed by the water absorbing member, the liquid may leak around.

The flow path 10 of the socket 1 and the flow path 20 of the plug 2 are connected. In this case, the surface of the sheet 12 of the socket 1 is in contact with the end surface 23 A of the insertion portion 23 of the plug 2, and the surface of the sheet 22 of the plug 2 is in contact with the bottom surface 13 A of the hole 13 of the socket 1.

  On the other hand, as shown in FIGS. 6A to 6F, when the shutters 15 and 25 are provided in the socket 1 and the plug 2, respectively, the flow path 10 of the socket 1 and the flow path 20 of the plug 2 In other words, the shutter 15 of the socket 1 and the shutter 25 of the plug 2 are closed in a state where the positions of the plugs 2 are positioned, that is, in the state where the flow path 20 of the plug 2 is located at a position facing the flow path 10 of the socket 1. The surface of the shutter 15 of the socket 1 is in contact with the end surface 23A of the insertion portion 23 of the plug 2, and the surface of the shutter 25 of the plug 2 is in contact with the bottom surface 13A of the hole 13 of the socket 1. For this reason, in the state where the socket 1 and the plug 2 are combined, the liquid is not absorbed by the sheets 12 and 22, and the sheets 12 and 22 can be kept dry. That is, only the liquid leaked when the socket 1 and the plug 2 of the coupler 3 are removed is absorbed by the sheets 12 and 22. When the insertion portion 23 of the plug 2 is pushed down to the bottom surface 13A of the hole 13 of the socket 1 with the flow path 10 of the socket 1 and the flow path 20 of the plug 2 aligned, the shutter 15 of the socket 1 is plugged. The shutter 25 of the plug 2 may be accommodated in the recess provided in the bottom surface 13A of the hole 13 of the socket 1. Note that in FIGS. 6A to 6F, the structure is omitted as appropriate for easy understanding of the description.

  When the projections 16 and 26 are provided on the socket 1 and the plug 2 of the coupler 3, respectively, the insertion portion 23 of the plug 2 is connected to the socket with the flow path 10 of the socket 1 and the flow path 20 of the plug 2 aligned. 1, the protrusion 16 of the socket 1 is stored in the storage hole 16 </ b> X provided in the end surface 23 </ b> A of the insertion part 23 of the plug 2, and the protrusion 26 of the plug 2 is stored in the socket 1. It is stored in a storage hole 26 </ b> X provided in the bottom surface 13 </ b> A of the hole 13.

  Further, when the notches 15A and 25A are provided in the shutters 15 and 25 of the socket 1 and the plug 2, respectively, the positions of the notches 15A and 25A match the positions of the storage holes 26X and 16X with the shutters 15 and 25 closed. You can do that. Then, when the insertion portion 23 of the plug 2 is pushed down to the bottom surface 13A of the hole 13 of the socket 1 in a state where the flow passage 10 of the socket 1 and the flow passage 20 of the plug 2 are aligned, the protruding portion 16 of the socket 1 is What is necessary is just to enter the notch 25A of the shutter 25 of the plug 2 so that the protrusion 26 of the plug 2 enters the notch 15A of the shutter 15 of the socket 1.

  On the other hand, when removing the socket 1 and the plug 2 of the coupler 3 of the present embodiment (at the time of detachment; when the connection is released), the insertion portion 23 of the plug 2 is pulled out from the hole 13 of the socket 1. Accordingly, the flow path 10 of the socket 1 is closed by the valve 11 provided in the flow path 10 of the socket 1, and the flow path 20 of the plug 2 is closed by the valve 21 provided in the flow path 20 of the plug 2. Thus, the outflow of liquid from the respective flow paths 10 and 20 of the socket 1 and the plug 2 is stopped [see FIG. 5A].

  At this time, the valve 11 provided in the flow path 10 of the socket 1 moves in a direction to close the flow path 10 of the socket 1, and the valve 21 provided in the flow path 20 of the plug 2 moves through the flow path 20 of the plug 2. Move in the closing direction. For this reason, the liquid that has entered the space in the movable range of the valves 11 and 21 is pushed out, and the liquid leaks from the open ends of the flow paths 10 and 20 of the socket 1 and the plug 2.

  Therefore, first, as shown in FIGS. 5G to 5I, the end face 23A of the insertion portion 23 of the plug 2 with the insertion portion 23 of the plug 2 slightly pulled out from the hole 13 of the socket 1. When viewed from the side, the plug 2 is rotated 90 degrees counterclockwise (counterclockwise). Here, the sheet 22 is provided at a position shifted 90 degrees clockwise with respect to the flow path 20 on the end surface 23A of the insertion portion 23 of the plug 2, and the sheet 12 is disposed on the bottom surface 13A of the hole 13 of the socket 1. It is provided at a position shifted 90 degrees clockwise with respect to the flow path 10. Therefore, the plug 2 is rotated 90 degrees counterclockwise from the state in which the flow path 20 of the plug 2 is positioned at a position facing the flow path 10 of the socket 1 [see FIGS. 5E and 5F]. Thus, as shown in FIGS. 5H and 5I, the sheet 22 of the plug 2 is positioned at a position facing the flow path 10 of the socket 1 and at a position facing the flow path 20 of the plug 2. The sheet 12 of the socket 1 can be located. Thereby, the liquid leaking from the opening end of the flow path 10 of the socket 1 (for example, water droplets adhering to the valve tip) can be wiped off with the sheet 22 provided on the end surface 23A of the insertion portion 23 of the plug 2. it can. Further, the liquid leaking from the opening end of the flow path 20 of the plug 2 (for example, water droplets adhering to the valve tip) can be wiped off with the sheet 12 provided on the bottom surface 13 </ b> A of the hole 13 of the socket 1. As described above, when the socket 1 and the plug 2 of the coupler 3 are removed, the liquid 3 leaks from the ends of the flow paths 10 and 20 when the socket 1 and the plug 2 of the coupler 3 are removed. Can be actively wiped off by separately provided sheets 12 and 22. That is, the liquid leaked when the socket 1 and the plug 2 of the coupler 3 are removed is wiped off and absorbed by the sheets 12 and 22 inside the coupler 3. Thereby, when removing the socket 1 and the plug 2 of the coupler 3, it can prevent reliably that a liquid leaks outside. That is, by providing a simple attachment / detachment structure, it is possible to reliably prevent the liquid leaked when the socket 1 and the plug 2 of the coupler 3 are removed from being scattered around.

  Here, as a positioning mechanism for slightly pulling out the insertion portion 23 of the plug 2 in the hole 13 of the socket 1, two O-rings 14 (2 A heavy O-ring structure) and a protrusion 24 on the side surface of the insertion portion 23 of the plug 2 may be used. That is, when the socket 1 and the plug 2 are coupled, as shown in FIG. 5D, the socket 1 is provided on the side surface of the insertion portion 23 of the plug 2 inside the O-ring 14 on the bottom surface 13A side of the hole 13 (bottom surface side). What is necessary is just to insert the insertion part 23 of the plug 2 in the hole 13 of the socket 1 so that the protruding part 24 may be located. On the other hand, when the insertion portion 23 of the plug 2 is slightly pulled out in the hole 13 of the socket 1, the insertion portion 23 of the plug 2 is interposed between the two O-rings 14 as shown in FIG. What is necessary is just to pull out the insertion part 23 of the plug 2 a little in the hole 13 of the socket 1 so that the protrusion part 24 provided in the side surface may be located.

  Further, as a guide mechanism for rotating 90 degrees with the insertion portion 23 of the plug 2 slightly pulled out in the hole 13 of the socket 1, for example, as shown in FIG. A rail 20 having a portion 30A extending in the circumferential direction between the two O-rings 14 and extending in a circumferential direction between the two O-rings 14 and extending a predetermined distance corresponding to 90 degrees is provided, and the side surface of the insertion portion 23 of the plug 2 is provided. It is sufficient to provide a protrusion 31 guided by the rail 20. When the socket 1 and the plug 2 are coupled, the protrusion 31 provided on the side surface of the insertion portion 23 of the plug 2 is guided by the rail 30 provided on the side wall of the hole 13 of the socket 1, and It moves to the farthest (that is, to the end of the hole 13 on the bottom surface 13A side). On the other hand, when the insertion portion 23 of the plug 2 is slightly pulled out in the hole 13 of the socket 1, the insertion portion 23 of the plug 2 is slightly pulled out so that the protrusion 24 is positioned between the two O-rings 14. [See FIG. 5G], the protrusion 31 is guided by the rail 30 and moves to the branching portion 30A. When the plug 2 is rotated in this state, the projection 31 is guided by the branching portion 30A of the rail 30 and moves in the circumferential direction, and stops at the end. In this way, the insertion portion 23 of the plug 2 can be rotated 90 degrees in a state where the insertion portion 23 of the plug 2 is slightly pulled out in the hole 13 of the socket 1.

  Further, when the shutters 15 and 25 are provided in the socket 1 and the plug 2, respectively, a state in which the flow path 20 of the plug 2 is located at a position facing the flow path 10 of the socket 1 [FIG. 6 (E), FIG. When the plug 2 is rotated 90 degrees counterclockwise from FIG. 6 (G) to FIG. 6 (I), the projections 16 and 26 provided on the socket 1 and the plug 2 are used as shown in FIGS. The shutters 25 and 15 are opened, and the sheets 22 and 12 are exposed.

  That is, the flow path 10 of the socket 1 and the flow path of the plug 2 from the state in which the flow path 20 of the plug 2 is located at a position facing the flow path 10 of the socket 1 [see FIG. 6 (E), FIG. 6 (F)]. When the plug 2 is rotated 90 degrees counterclockwise so as to be displaced from the position 20, the shutter 15 of the socket 1 is opened by the protrusion 26 of the plug 2 so that the sheet 12 is exposed, and the protrusion of the socket 1 is exposed. 16, the shutter 25 of the plug 2 is opened, and the sheet 22 is exposed.

  Specifically, the plug 2 is turned 90 degrees counterclockwise from the state in which the flow path 20 of the plug 2 is located at a position facing the flow path 10 of the socket 1 [see FIGS. 6E and 6F]. When rotated, the protrusion 26 of the plug 2 rotates 90 degrees as shown in FIG. When the plug 2 is slightly pulled out in a state where the flow path 20 of the plug 2 is located at a position facing the flow path 10 of the socket 1, the protrusion 26 of the plug 2 is a closed shutter provided in the socket 1. 15 (see FIGS. 6E and 6F). For this reason, when the protrusion 26 of the plug 2 is rotated 90 degrees, the closed shutter 15 provided in the socket 1 is rotated 90 degrees to be in the open state, and the sheet 12 provided below the exposed shutter 12 is exposed. . On the other hand, when the plug 2 is rotated 90 degrees counterclockwise from the state in which the flow path 20 of the plug 2 is positioned at a position facing the flow path 10 of the socket 1 (see FIGS. 6E and 6F). The movement of the shutter 25 provided on the plug 2 is restricted by the projection 16 of the socket 1, and the sheet 22 provided on the lower side thereof rotates 90 degrees. When the plug 2 is slightly pulled out in a state in which the flow path 20 of the plug 2 is positioned at a position facing the flow path 10 of the socket 1 [see FIGS. 6E and 6F], the protrusion of the socket 1 The portion 16 is in contact with the side surface of the closed shutter 25 provided on the plug 2. For this reason, when the shutter 25 provided on the plug 2 does not move and the sheet 22 provided on the lower side thereof rotates 90 degrees, the shutter 25 provided on the plug 2 is opened, and the lower side thereof. The sheet 22 provided on the surface is exposed.

Thereby, the liquid (for example, water droplets) leaking from the opening end of the flow path 10 of the socket 1 can be wiped off with the sheet 22 provided on the end surface 23A of the insertion portion 23 of the plug 2. Further, the liquid (for example, water droplets) leaking from the opening end of the flow path 20 of the plug 2 can be wiped off with the sheet 12 provided on the bottom surface 13 </ b> A of the hole 13 of the socket 1.
Although the plug 2 is rotated 90 degrees here, the present invention is not limited to this, and the socket 1 may be rotated 90 degrees. That is, the positions of the flow path 10 of the socket 1 and the flow path 20 of the plug 2 are shifted by 90 degrees, and the sheet 22 of the plug 2 is positioned at a position facing the flow path 10 of the socket 1. What is necessary is just to rotate at least one of the socket 1 and the plug 2 so that the sheet | seat 12 of the socket 1 may be located in the position which opposes. In addition, here, the position where the sheets 12 and 22 are provided is shifted by 90 degrees with respect to the flow paths 10 and 20, and the socket 1 or the plug 2 is rotated by 90 degrees. Instead, the position where the sheets 12 and 22 are provided is shifted by a predetermined angle with respect to the flow paths 10 and 20, and the socket 1 or the plug 2 is rotated by a predetermined angle. Further, the direction in which the positions where the sheets 12 and 22 are provided with respect to the flow paths 10 and 20 and the direction in which the socket 1 or the plug 2 is rotated may also be reversed. In short, when the position of the flow path 10 of the socket 1 and the position of the flow path 20 of the plug 2 are shifted by rotating the socket 1 or the plug 2, the flow path 10 of the socket 1 and the sheet 22 of the plug 2 face each other. Then, the flow path 20 of the plug 2 and the sheet 12 of the socket 1 may be opposed to each other.

  Further, when the filters 18 and 28 and the conduits 19 and 29 are provided in the socket 1 and the plug 2, respectively (see, for example, FIG. 4), the liquid (which is wiped off as described above and contained in the sheets 12 and 22) Water here is guided to the filters 18 and 28 through the conduits 19 and 29, and is discharged to the outside as a gas (here, water vapor) through the filters 18 and 28. Thereby, it is possible to prevent the liquid absorbed by the sheets 12 and 22 from leaking again.

  In this manner, the plug 2 can be rotated 90 degrees counterclockwise (counterclockwise) with the insertion portion 23 of the plug 2 slightly pulled out in the hole 13 of the socket 1, and the flow path 10 of the socket 1 can be The liquid leaking from the opening end and the liquid leaking from the opening end of the flow path 20 of the plug 2 are respectively the sheet 22 provided on the end surface 23A of the insertion portion 23 of the plug 2 and the socket 1 The sheet 12 provided on the bottom surface 13A of the hole 13 can be wiped off simultaneously.

Thereafter, the socket 1 and the plug 2 of the coupler 3 can be removed by completely pulling out the insertion portion 23 of the plug 2 from the hole 13 of the socket 1. As a result, the socket 1 and the plug 2 of the coupler 3 can be removed while preventing the liquid from leaking.
Therefore, according to the coupler concerning this embodiment, there exists an advantage that it can prevent reliably that a liquid leaks at the time of removal of the socket 1 and the plug 2 of the coupler 3. FIG. That is, it is possible to realize the coupler 3 in which liquid does not leak during attachment / detachment.
