[0001]
[Field of the Invention]
The present invention relates to a fluid connector that can be freely connected to and separated from the other connector and that exchanges fluid with the connector.
[0002]
[Prior art]
In recent years, fuel cells have attracted attention as power generation devices that generate electrical energy. A fuel cell is a device that extracts, as electric energy, energy generated when hydrogen and oxygen react to produce water. A fuel cell is a clean power generation device that is friendly to the global environment because it produces no harmful by-products when taking out electric energy, and is expected to be used more and more in the future.
[0003]
By the way, hydrogen which is the fuel of the fuel cell is supplied to the fuel cell from a hydrogen storage device including a storage tank for storing the fuel cell in a liquid or gas state, a hydrogen cartridge including a hydrogen storage alloy, and the like.
[0004]
[Problems to be solved by the invention]
By the way, when the distribution and transactions of hydrogen become common with the spread of fuel cells, in order to smoothly supply hydrogen, both the state and specifications of both sides between the hydrogen supply side and the reception side are required. Information exchange is required.
[0005]
Specifically, for example, assuming that the hydrogen storage device is used detachably with respect to a fuel cell or a hydrogen replenishment device that replenishes hydrogen, the hydrogen storage device is replenished with hydrogen, or the hydrogen storage device When the hydrogen stored in the battery is supplied to the fuel cell, for example, information such as the type of hydrogen storage alloy, internal temperature, hydrogen pressure, or remaining amount of hydrogen is exchanged prior to receiving or supplying hydrogen. It is required to do.
[0006]
In order to respond to such a request, it is conceivable that the hydrogen storage device is provided with a communication function, an information storage function, etc., and various signals are transmitted and received between the hydrogen storage device and various devices. .
[0007]
However, pipe joints (connectors) that have been used in the past have the highest priority on the sealing performance (sealing performance) of liquids and gases that are transported inside. For connection of signal lines that transmit electrical signals, etc. Not considered. Therefore, when both the flow path of the fluid such as liquid and gas and the signal line are connected between the apparatuses, it is necessary to connect the flow path and the signal line with separate connectors. For this reason, there are problems in that connection mistakes are likely to occur and connection operations are complicated.
[0008]
Further, as shown in, for example, Japanese Patent Application Laid-Open No. 10-139401, a connector in which a fluid flow path and a signal line are integrally formed has been proposed. There is a problem that a fluid flow path and a signal line connecting portion are required separately, and connection failure is likely to occur.
[0009]
In addition, for example, in the case of supplying fluid after detecting that the connectors are securely connected with each other for the purpose of preventing fluid leakage at the connection portion between the connectors, the connection between these connectors is detected. In addition, it is necessary to provide a signal line for detecting connection separately from the signal line for transmitting and receiving information. In this case, there is a problem that the structure of the connecting portion of the connector is complicated and a new signal line is required, resulting in an increase in cost.
[0010]
Accordingly, the present invention has been made in view of the above-described conventional situation, and provides a fluid connector and a fluid connector device capable of reliably connecting fluid flow paths and transmitting and receiving signals between the connectors. The purpose is to do.
[0011]

[0012]
The fluid connector according to claim 1 of the present invention configured as described above has a flow path and a pair of terminal portions, and these terminal portions are located on the connection surface of the other connector. By connecting the fluid flow path, the terminal portion is naturally connected. In addition, the terminal portion transmits a signal related to fluid supply control to the other connector. Therefore, a function as a signal line for transmitting a signal is exhibited in the pipe itself constituting the fluid flow path.
[0015]
  Also,UpThe contact between the first terminal portion and the terminal portion of the other connector in the second terminal portion is:By providing a protrusion on the first terminal portionIt may be arranged side by side in the insertion direction of the other connector. This connects the connectors togetherWhenThe terminal portions can be naturally connected to each other, and the terminal portions are securely connected to each other without considering the orientation and position of connecting the pair of terminal portions to the terminal portion of the other connector. be able to.
[0016]

[0017]
  The present invention configured as described above.Claim 3The fluid connector which concerns on can connect the connection state of connectors reliably by a locking mechanism. In addition, since the pair of terminal portions are connected to the other connector in a state where the connectors are fixed to each other by the lock mechanism, when the supply or reception of fluid is started, the physical connection state between the connectors and It is no longer necessary to check the electrical connection state at the terminal part, for example, it is determined that the physical connection between the connectors has been secured by detecting that the signal has been transmitted by the terminal part, and the fluid supply Or start receiving.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Prior to describing a specific configuration example to which the present invention is applied, a basic schematic configuration of a fluid connector according to the present invention will be described with reference to the drawings.
[0019]
FIG. 1 is a schematic end view of a fluid connector 10 shown as a first basic configuration example to which the present invention is applied, as viewed from a connection surface between connectors. The fluid connector 10 of this example includes a cylindrical pipe 11 formed of a conductive material, and an internal space of the pipe 11 indicated by an arrow A in the figure is configured as a fluid flow path. Further, an insulating member 12 is disposed over the entire outer periphery of the pipe 11, and a first conductive member 13 and a second conductive member 14 are further provided on the outer peripheral portion of the insulating member 12. Are arranged.
[0020]
The first conductive member 13 and the second conductive member 14 are respectively arranged around the insulating member 12 over a half circumference by a conductive material such as a metal material. Further, an insulating member 15 is disposed between the first conductive member 13 and the second conductive member 14, thereby ensuring mutual insulation.
[0021]
In the fluid connector 10 configured as described above, the pipes 11 constituting the fluid flow path are connected to the other connector, and the first conductive member 13 and the second conductive member 14 are connected. They are connected to each other. For example, one of the first conductive member 13 and the second conductive member 14 is used as a ground wire, and the other is used as a signal wire, and a signal related to fluid supply control between the connectors is transmitted. Communicated.
[0022]
That is, the first conductive member 13 and the second conductive member 14 have a function as a signal line for transmitting a signal, and the connection surface with the other connector has a terminal portion for transmitting the signal. As a function. Therefore, the fluid connector 10 naturally connects the signal line by connecting the pipe 11 constituting the fluid flow path to the other connector.
[0023]
In addition, the outer periphery of the first conductive member 13 and the second conductive member 14 is further covered with various resin materials to improve the insulation of the signal line, and at the same time, the signal line due to the external environment. It may be possible to prevent deterioration or damage.
[0024]
Next, a fluid connector 20 as shown in FIG. 2 will be described as a second basic configuration example to which the present invention is applied. FIG. 2 is a schematic end view of the fluid connector 20 as seen from the connection surface between the connectors.
[0025]
The fluid connector 20 of this example is an example in which the piping 11 in the fluid connector 10 is omitted and the cylindrical insulating member 12 itself has a function as a piping. That is, the internal space of the insulating member 12 indicated by the arrow A in the figure is configured as a fluid flow path.
[0026]
For example, when the pressure of the fluid flowing in the flow path is sufficiently low and sufficient mechanical strength is obtained by the insulating member 12, the piping 11 may be omitted. Thereby, the structure as a whole can be simplified, the number of parts can be reduced, and cost reduction can be achieved.
[0027]
Next, a fluid connector 30 as shown in FIG. 3 will be described as a third basic configuration example by applying the present invention. FIG. 3 is a schematic end view of the fluid connector 30 as seen from the connection surface between the connectors.
[0028]
The fluid connector 30 of the present example has a function as the first conductive member 13, that is, a function as a signal line, in the pipe 11 itself in the fluid connector 10, and the insulating member 12 disposed around the pipe 11. This is an example in which the second conductive member 14 is disposed over the entire circumference of the outer peripheral portion.
[0029]
For example, a signal is sent to the pipe 11 itself and used as a signal line, and the second conductive member 14 is used as a ground line, thereby transmitting a signal related to fluid supply control to the other connector.
[0030]
Thus, in order to use the piping 11 itself as a signal line, it is necessary that the fluid conveyed in the flow path has sufficient electrical insulation. For example, when transporting hydrogen gas, since the hydrogen gas has sufficient electrical insulation, the pipe 11 itself is connected to the signal line by applying a voltage or supplying a current to the pipe 11. There is no problem even if it is used.
[0031]
Next, a case of connecting a pair of connectors based on the configuration of the fluid connector 30 described above will be described with reference to FIGS. 4 and 5 are schematic cross-sectional views schematically showing a cross section of a pair of connectors. In the following description, the left connector in the figure is referred to as a male connector 40 for convenience, and the right connector in the figure is referred to as a female connector 50. FIG. 4 shows a state in which these connectors are separated from each other, and FIG. 5 shows a state in which these connectors are connected to each other.
[0032]
The male connector 40 is configured based on the configuration of the fluid connector 30 described above, and is formed of a conductive material and has a pipe 11 having a function as the first conductive member 13, and around the pipe 11. It has the 2nd electroconductive member 14 arrange | positioned in the outer peripheral part of the piping 11 through the formed insulating member 12. As shown in FIG.
[0033]
Similarly, the female connector 50 is configured based on the configuration of the fluid connector 30 described above, and is formed of a conductive material and has a function as the first conductive member 13 and the pipe 11. 11 and a second conductive member 14 disposed on the outer periphery of the pipe 11 through an insulating member 12 formed around the periphery of the pipe 11.
[0034]
The second conductive member 14 of the female connector 50 is formed with an inner diameter substantially equal to the outer diameter of the second conductive member 14 of the male connector 40. Thereby, as shown in FIG. 5, when connecting connectors, the 2nd electroconductive members 14 are fitted and electrically connected.
[0035]
The female connector 50 includes a connection portion 51 at the end of the pipe 11 at a position near the connection surface between the connectors. The connecting portion 51 has a function of connecting a fluid flow path between the pipe 11 on the male connector 40 side and the pipe 11 on the female connector 50 side in a state where the pipe 11 of the male connector 40 is connected. is doing. In addition, a seal member 52 made of, for example, various O-rings is attached to a position where the pipe 11 of the male connector 40 is abutted in the connection portion 51. The seal member 52 has a function of preventing fluid from leaking at the connection position when the pipes 11 between the connectors are connected.
[0036]
Since the male connector 40 and the female connector 50 configured as described above are connected as shown in FIG. 5, the pipes 11 and the second conductive members 14 are connected to each other. By performing the operation of connecting the fluid flow paths, the signal lines are naturally connected. Therefore, the signal line can also be connected by one operation of connecting the pipes 11 to each other, for example, compared to the case where the flow path for transporting the fluid and the signal line for transmitting the signal are separately connected, The labor required for connection can be significantly reduced. Further, there is no connection error or connection failure, and the flow path for transporting the fluid and the signal line for transmitting the signal can be simply and reliably connected.
[0037]
For example, as shown in FIG. 6, the insulating member 12 and the second conductive member 14 extend along the pipe 11, and a male connector 40 and a female connector 50 are provided at both ends of the pipe 11, respectively. It is good. As a result, the flow path for transporting the fluid and the signal line for transmitting the signal can be extended simply by connecting and adding the pipes 11 one after another.
[0038]
In the male connector 40 and the female connector 50, the connection portion (terminal portion) between the pipes 11 as the first conductive member 13 and the connection portion (terminal portion) between the second conductive members 14 are used. May be arranged side by side in the direction of insertion when the connector is connected.
[0039]
In this case, for example, as shown in FIGS. 7 and 8, a protrusion 13 a is provided at the end of the pipe 11 as a male connector 40. The protrusion 13a is attached in a state of being electrically connected to the pipe 11, and protrudes to a height that forms substantially the same plane as the second conductive member 14. The second conductive member 14 is disposed downstream of the protrusion 13a, and the insulating member 12 is interposed between the protrusion 13a and the second conductive member 14.
[0040]
Further, the connecting portion 51 and the second conductive member 14 of the female connector 50 are in contact with each other at positions corresponding to the protrusion 13a and the second conductive member 14 of the male connector 40, and the connectors are connected. It is arranged in a shape and a position where it is electrically connected in the state where it is connected. That is, in the female connector 50, the connection portion (terminal portion) of the connection portion 51 with the protrusion 13 a of the male connector 40 and the second conductive member of the male connector 40 in the second conductive member 14. 14 are arranged side by side in the direction in which the male connector 40 is inserted when the connectors are connected to each other.
[0041]
As described above, the terminal portions of the male connector 40 and the female connector 50 may be arranged side by side in the insertion direction of the connectors. Thereby, by connecting the connectors, the terminal portions can be connected with each other, and without considering the orientation and position of connecting the pair of terminal portions to the terminal portion of the other connector. Each terminal part can be reliably connected.
[0042]
Even in this case, for example, as shown in FIG. 9, the insulating member 12 and the second conductive member 14 are extended along the pipe 11, and the male connector 40 is connected to both ends of the pipe 11. A female connector 50 may be provided. As a result, the flow path for transporting the fluid and the signal line for transmitting the signal can be extended simply by connecting and adding the pipes 11 one after another.
[0043]
Below, based on the basic structure demonstrated above, a pair of fluid connector shown in FIG.10 and FIG.11 is demonstrated as a specific structural example to which this invention is applied. In the following description, for convenience, the fluid connector shown on the right side in the figure is referred to as a male connector 60, and the fluid connector shown on the left side in the figure is referred to as a female connector 70. FIG. 10 is a cross-sectional view showing a state where the male connector 60 and the male connector 70 are connected.
[0044]
In the following description, it is assumed that gaseous hydrogen is supplied from the male connector 60 side to the female connector 80 side. That is, the male connector 60 is the hydrogen supply side, and the female connector 80 is the hydrogen receiving side.
[0045]
However, the present invention is not particularly limited to application to the case of transferring hydrogen, and can be widely applied to the case of transferring a liquid or gaseous fluid such as oxygen, methane, or water. Further, the direction in which the fluid is conveyed is not particularly limited, and for example, the fluid may be conveyed in both directions.
[0046]
First, the male connector 60 will be described. As shown in FIGS. 10 and 11, the male connector 60 includes a connector body 61 formed of, for example, a metal material. The connector main body 61 is attached to an apparatus main body 100 such as a hydrogen storage device or a fuel cell.
[0047]
Inside the connector main body 61, a flow path 62 penetrating between the connection surface between the connectors and the other end surface is formed. That is, the connector main body 61 is formed in a hollow shape, and the internal space is configured as the flow path 62. Then, hydrogen is transported in the flow path 62.
[0048]
A mechanical valve mechanism 90 is disposed in the flow path 62. As shown in FIG. 10, the valve mechanism 90 includes a valve 91 that is movable in the axial direction of the connector main body 61 along the flow path 62, and a stopper that restricts the movement of the valve 91 on the connection surface side between the connectors. The member 92, the coil spring 93 that urges the valve 91 in the direction of the connection surface between the connectors, and the inner peripheral surface of the connector main body 61 in a state where the valve 91 is abutted against the stopper member 92. And an O-ring 94 that is in close contact with each other.
[0049]
In the normal state, the valve mechanism 90 is urged toward the stopper member 92 by the coil spring 93 and the O-ring 94 is in close contact with the inner peripheral surface of the connector main body 61. Thus, in a normal state, the flow path 62 is closed.
[0050]
In the valve mechanism 90, the valve 91 is moved against the urging force of the coil spring 93 by the member on the female connector 80 side in a state where the male connector 60 and the female connector 80 are connected. As a result, the O-ring 94 is separated from the inner peripheral surface of the connector body 61 and the flow path 62 is opened at the connection surface.
[0051]
Since the male connector 60 includes the valve mechanism 90 as described above, even if hydrogen is accidentally transported without being connected to the female connector 80, the hydrogen leaks. Can be prevented.
[0052]
In addition, the male connector 60 is positioned on the connection surface between the connectors, and an O-ring 63 is disposed outside the open portion of the flow path 62. The O-ring 63 has a function of preventing hydrogen from leaking at the connection surface when the male connector 60 and the female connector 80 are connected.
[0053]
In the male connector 60, a conductive member 65 is disposed on the outer periphery of the connector main body 61 via an insulating member 64.
[0054]
Next, the female connector 80 will be described. Since the female connector 80 has substantially the same configuration as the male connector 60, the description of the same or equivalent parts as the male connector 60 is omitted below, and the same reference numerals are used in the drawings. It will be shown in.
[0055]
In FIG. 11, the female connector 80 is attached to the apparatus main body 100 such as a hydrogen storage device or a fuel cell, and the end opposite to the connection surface between the connectors is shown in FIG. The figure shows a case where a hydrogen pipe 200 is connected.
[0056]
In this case, as shown in FIG. 11, an O-ring 81 and an O-ring 82 are provided on the inner peripheral surface of the connector main body 61 and the end surface opposite to the connection surface between the connectors at the site where the pipe 200 is connected. It is desirable to arrange. Thereby, it is possible to prevent hydrogen from leaking at the connection portion of the pipe 200.
[0057]
Further, the connector main body 61 in the female connector 80 is a portion connected to the male connector 60 and has an inner shape corresponding to the outer shape of the connector main body 61 on the male connector 60 side. Thus, the connector body 61 is contacted and fitted in a state of being connected to the connector body 61 on the male connector 60 side, and electrical conduction between the connector bodies 61 is achieved.
[0058]
The female connector 80 is provided with a lock mechanism 150 for fixing the connection state between the connectors. The lock mechanism 150 is disposed on the peripheral surface of the connector main body 61, and is a lock plate 151 that is movable in the radial direction of the flow path 62, and a spring 152 that biases the lock plate 151 outward from the connector main body 61. And the lock pin 153 which latches the lock plate 151 is arrange | positioned. The lock pin 153 is biased in the direction of the joint surface with the male connector 60 by the spring 154, but movement in the joint surface direction is restricted by the lock plate 151.
[0059]
The lock plate 151 is formed of a conductive material, and the lock pin 153 is formed of a material having electrical insulation.
[0060]
In the case where the female connector 80 having the lock mechanism 150 configured as described above and the male connector 60 are joined, if both connectors are joined at the joining surface, the spring 154 resists the urging force. The lock pin 153 is pushed leftward in the figure by the connection surface of the male connector 60. As a result, the lock plate 151 locked by the lock pin 153 is released from the locked state and becomes movable, and moves upward in the figure by the urging force of the spring 152. As a result, the end of the lock plate 151 is inserted into the lock groove 155 formed in the male connector 60.
[0061]
In this manner, the end of the lock plate 151 disposed in the female connector 80 is inserted into the lock groove 155 formed in the male connector 60, so that the male connector 60 and the female connector 80 are connected. It is locked and the joining state is fixed.
[0062]
In this state, the conductive member 65 of the male connector 60 and the conductive member 65 of the female connector 80 are electrically connected via the lock plate 151 to achieve electrical conduction. Thereby, for example, a ground potential (ground potential), a signal for controlling the supply of fluid, and the like are transmitted between the male connector 60 and the female connector 80 through the conductive member 65.
[0063]
At the same time, the flow paths 12 of the male connector 60 and the female connector 80 are connected, and hydrogen is supplied or received through the male connector 60 and the female connector 80. Specifically, hydrogen is supplied from the flow path 12 on the male connector 60 side to the female connector 80 side through through holes 91a, 91b, 91c provided in the valve 91. On the female connector 80 side, hydrogen supplied from the male connector 60 is supplied to the flow path 12 through through holes 91 d and 91 e provided in the valve 91.
[0064]
On the other hand, when the male connector 60 and the female connector 80 are removed, the lock plate 151 is pushed downward against the urging force of the spring 152 so that the end of the lock plate 151 is moved. It moves from the lock groove 155 and is in a state of being removable. At this time, since the lock plate 151 disposed on the female connector 80 side is detached from the lock groove 155 formed on the male connector 60 side, the conductive member 64 is between the connectors. Electrically insulated.
[0065]
Next, when the male connector 60 and the female connector 80 are separated from each other, the lock pin 153 moves to the right in the drawing, and the end of the lock plate 151 is locked.
[0066]
In this way, by adopting a configuration in which the connection state between the connectors is fixed by the lock mechanism 150, it is possible to prevent the connectors from being accidentally disconnected.
[0067]
  The male connector 60 and the female connector 80 are configured such that the conductive members 64 are electrically connected for the first time in a state where the lock mechanism 150 is locked. Therefore, it is not necessary to confirm the physical connection state between the connectors and the electrical connection state at the terminal portion when starting supply or reception of hydrogen. Specifically, the conductive members 64 are connected to each other, for example, by detecting that the ground potential of both is the same potential, or that a signal for controlling the supply and reception of hydrogen is transmitted. It can be determined that the physical connection has been secured. Therefore, after detecting the physical connection state in this way, supply and reception of fluid can be started, and hydrogen leaks at the connection part between the connectors.Preventioncan do.
[0068]
In addition, the transmission / reception system of the signal transmitted between these male connector 60 and female connector 80 is not specifically limited, For example, various transmission / reception systems, such as serial communication and CAN, are employable.
[0069]
Further, as shown in FIGS. 6 and 9, signals transmitted between the male connector 60 and the female connector 80 by the pipe 11 and the conductive member 65 are transmitted by the pipe 11 and the conductive member 65 itself. However, it may be transmitted to other pipes and devices, but may be transmitted in the form of light, sound waves, electromagnetic waves (radio waves), etc. by performing various signal conversions in these connectors, for example. . Further, for example, as shown in FIG. 11, the terminal 160 may be connected to the connector main body 61 or the conductive member 65, and the signal may be transmitted to other pipes and devices through the signal line 161.
[0070]
In the above description, the signal and hydrogen are unilaterally sent from the male connector 60 side to the female connector 80 side. However, the signal sending direction and the hydrogen sending direction are not necessarily the same. Good. Specifically, for example, a signal may be sent from the male connector 60 side to the female connector 80 side, and hydrogen may be sent from the female connector 80 side to the male connector 60 side. Conversely, a signal may be sent from the female connector 80 side to the male connector 60 side, and hydrogen may be sent from the male connector 10 side to the female connector 80 side.
【The invention's effect】
Since the fluid connector according to the present invention includes an electromagnetic coil, when a voltage is applied to the electromagnetic coil, the fluid connector is attracted to the other connector or transmits a signal to the other connector. It can have various functions.
[0071]
Further, the fluid connector device according to the present invention can adsorb the fluid connectors to each other and reliably join them by the electromagnetic force generated by applying a voltage to the electromagnetic coil. Further, by varying the voltage applied to the electromagnetic coil, a signal can be transmitted from one electromagnetic coil to the other electromagnetic coil using electromagnetic induction.
[0072]
Therefore, according to the present invention, it is possible to realize a fluid connector and a fluid connector device capable of reliably connecting fluid flow paths and transmitting and receiving signals between the connectors.
