  6-11 illustrate another preferred embodiment of the composite connector system of the present invention.

  FIG. 6 is a perspective view showing another preferred embodiment of the composite connector system, and FIG. 7 shows that the composite connectors 10A and 10B are positioned on the first connection object 20 and the second connection object 202 using a key structure. An example is shown.

  The composite connector system 1 shown in FIG. 6 has basically the same structure as the composite connector system 1 shown in FIG. 1, but differs in the following points.

  The composite connectors 10A and 10B of the composite connector system 1 of FIG. 1 have guide pins 31A and 31B, respectively, whereas the composite connectors 10A and 10B of the composite connector system 1 of FIG. Instead of a certain guide pin, keys 600 and 600 as positioning means are provided. In the composite connectors 10A and 10B of the composite connector system 1 of FIG. 6, the key 600 serves as a contact point for energization instead of the energization function of the guide pins 31A and 31B. The keys 600 and 600 are electrically connected to the energization units 33A and 33B. As shown in FIG. 7, these keys 600 and 600 are electrically and mechanically connected to the electrical connection members 850 and 850 in the connection objects 201 and 202.

  The keys 600 and 600 shown in FIG. 6 are also called protrusions and are formed in the X direction. As shown in FIG. 7, the keys 600 and 600 are inserted into the groove portions 650 of the electrical connection members 850 and 850, whereby the composite connectors 10A and 10B can be accurately positioned in the Y direction and the Z direction. The key 600 and the electrical connection member 850 have a connection fixing structure with a key structure.

  Next, another preferred embodiment of the composite connector system 1 of the present invention will be described with reference to FIG. FIG. 8 shows a state where the composite connectors 10 </ b> A and 10 </ b> B of the composite connector system 1 are connected to the first connection object 201 and the second connection object 202.

  The composite connectors 10A and 10B of the composite connector system 1 shown in FIG. 8 are detachably connected and fixed to the first connection object 201 and the second connection object 202 by a clamp mechanism 700 which is an example of a fixing means. Has been.

  Two sets of clamp mechanisms 700 are applied to each composite connector 10A, 10B, and the clamp mechanism 700 has a screw 701 and an attachment member 702. The attachment member 702 is fixed to the composite connectors 10A and 10B.

  The screw 701 is screwed into the female screw 711 of each surface 205, 206 of the first connection object 201 and the second connection object 202 through the hole 703 of the attachment member 702, so that the composite connectors 10A, 10B It is fixed to 206 so that attachment or detachment is possible. Accordingly, the composite connectors 10A and 10B can be accurately positioned and fixed to the first connection object 201 and the second connection object 202 by the clamp mechanism 700. Further, the fixing work when fixing the composite connectors 10A and 10B to the first connection object 201 and the second connection object 202 can be simplified, and the attachment / detachment work can be performed in a small work area.

  Next, another preferred embodiment of the composite connector system 1 of the present invention will be described with reference to FIG. In the embodiment shown in FIG. 9, the first connection object 201 and the first composite connector 10A side are representatively shown. However, the structure of the clamp structure 700, the attachment / detachment signal transmission means 800, and the electrical connectors 740 and 741 shown in FIG. 9 is the same in the second connection object 202 and the second composite connector 10B.

  The clamp mechanism 700 of the embodiment shown in FIG. 9 is an example of a fixing unit, and is basically the same as the clamp mechanism 700 of the embodiment shown in FIG. However, in the embodiment of FIG. 9, one electrical connector 740 is disposed on the attachment member 702, and the other electrical connector 741 is disposed on the surface 205 of the first connection target 201. These electrical connectors 740 and 741 are located at corresponding positions. When the attachment member 702 of the clamp mechanism 700 is fixed to the surface 205 (206) with the screw 701, the electrical connectors 740 and 741 are in close contact with each other. And are electrically connected.

  The electrical connectors 740 and 741 are connected to the attachment / detachment signal transmission means 800. These electrical connectors 740 and 741 are electrical contacts of the clamp mechanism 700. The attachment / detachment signal transmission unit 800 transmits the connection signal S1 to the warning unit 801 in the holding state in which the electrical contact state of the electrical connectors 740 and 741 is held, and is released in the release state in which the electrical contact state is released. Signal S2 is transmitted to warning means 801. For example, when the clamp mechanism 700 holds the composite connector 10A completely attached, the connection signal S1 is transmitted to the warning means 801, and the composite connector 10A is not fully attached or the composite connector 10A is removed. In the case of the release, the release signal S2 is transmitted to the warning means 801.

  When the release signal S2 is transmitted, for example, the warning unit 801 is activated, and a warning signal can be generated by sound or light. For example, when the warning signal is generated by sound, the warning unit 801 is a speaker, and when the warning signal is generated by light, the warning unit 801 can be a light emitting diode lamp. The warning unit 801 is disposed in the control unit 351. Accordingly, it is possible to reliably check whether the composite connectors 10A and 10B are detached from the first connection object 201 and the second connection object 202 or loosely attached.

  Such an attaching / detaching signal transmitting means 800 and alarm means 801 can be used even when the electrical connection state of the guide pin 31A (guide pin 31B) as the positioning means shown in FIG. The release signal S2 may be transmitted from the attachment / detachment signal transmission unit 800 to the alarm unit 801.

  The attachment / detachment signal transmission means 800 as described above can also be referred to as an attachment / detachment sensor, can monitor malfunction of the composite connectors 10A and 10B, and can monitor the quality of the electrical connection state in real time, thereby improving safety.

One end portion 24D and the other end portion 24E of the transport path portion 24C can be detachably connected to the transport path portion 24A of the composite connector 10A and the transport path portion 24B of the composite connector 10B, respectively, as indicated by arrows in FIG. Thereby, instead of the unit 900 of the catalytic action region 60, a unit of the same type or another type of unit can be newly connected simply and reliably between the composite connectors 10A and 10B.

They are arranged side by side on the connection portions 43A and 43B side of 30A and 30B. Thereby, different media such as electricity, gas, liquid, light, heat and the like can be connected at the same time and held in an airtight and liquidtight state to be securely connected to each other.
