2. Description of the Related Art Conventionally, an actuator, a lamp, a sensor, or the like is attached to an opening / closing body, and the operation of each part of the opening / closing body is controlled by a control means (ECU) on an opening / closing object side to which the opening / closing body is attached. In this case, a method is adopted in which loads such as the actuators are individually mounted on the opening / closing body, and these loads and the ECU are connected by a number of harnesses. For example, a description will be given of a case of an automobile door as the opening / closing body. As shown in FIG.
1 ', a door lock motor 121, a power window motor 122, and a door mirror storing motor 12
3, various loads such as the door coat lamp 125 are individually assembled, and a number of door harnesses 201 individually connected to the connectors of these various loads by the connector 201a are wired in the door 21 ', and A collective connector 201b in which each end of the harness 201 is assembled is disposed near the door hinge. The ECU 21 provided on the vehicle body side

21 to 123 and 125 are connected. Finally, the door trim 22 is assembled on the inner side to complete the door of the vehicle.

[0003]

However, in the method of mounting various loads such as actuators on the opening / closing body and wiring the various loads as described above, the various loads 120 and the various loads are provided as shown in FIG. In addition to the need to separately install the harness 201 for each of the 120,
Since it is necessary to connect the individual harnesses 201 for each of the loads 120 with the connectors 201a and 120a to each other in the state of being mounted on the door, the work for mounting and connecting those harnesses becomes complicated and time-consuming. I have. In addition, the above-mentioned inspection for checking the operation of the various loads 120 can be performed only after the vehicle is actually mounted on the door and connected to the ECU 210 on the vehicle body side. Work will be required.

Also, since it is necessary to wire a large number of harnesses 211, 211,...

a 'and the other end side connector 1 of the door side ECU 15'.
5b 'for the connector 201 of the door harness 201
b may be connected.

[0005] However, even if the multiplex communication is used in this way, the connector connection between the various loads 120 and the door harness 201, and the door harness 201 and the door-side ECU 15 '.
It is necessary to perform a large number of connector connections, such as a connector connection between the two, and the number of components is increased due to the large number of connectors. In addition, even when multiplex communication is adopted, it is necessary to individually assemble various loads and door harnesses inside the door, and the complexity of the assembling operation still remains.

The storage portions 111 to 115 to which the coating lamps 125 can be respectively attached and the storage portions 116 to which the coupling connectors 130 are to be formed are formed, and in addition, the coupling point connectors 130 and the loads 121 to 125 are individually coupled. .. (Mainly see FIG. 3) can be wired.

As shown in FIGS. 4 and 5, the connection point connector 130 includes a connector housing 132 (shown only in FIG. 4) and an IC (integrated circuit) board for multiplex communication built in the connector housing 132. 133 and three input / output terminals 134 and 13 connected to the multiplex communication line 16.
, 134, and a corresponding number of input / output terminals 135, 13 for inputting and outputting signals to and from the various loads 120 individually.
, And harnesses 131, 131,... Connected to the input / output terminals 135 by welding or the like. As each of the harnesses 131, it is compact to use a flat wiring body in which a wiring pattern composed of a plurality of narrow copper foil conductors is pressed between a pair of insulating films to form a flexible and flat shape. It is preferable from the viewpoint.

The multiplex communication line 16 is a multiplex communication line 1.
61 (see FIG. 5), the power supply line 162, and the GND line 163, and a fitting recess 136 into which the bus-side connector 16a is fitted in the input terminal 134 side of the connector housing 132. Are formed.

As shown in FIG. 6, the IC board 133 includes a power supply circuit 137, a communication circuit 138, a load drive circuit 139, and a detection circuit 140. The power supply circuit 137 receives the power supply line 162 and the GND 163 and supplies a voltage transformed for the communication circuit 138 to the communication circuit 138, the load driving circuit 139 and the detection circuit 1.
For example, a power supply voltage is applied to the power supply 40. In addition, it also plays a role of monitoring abnormalities in the voltage value of the power supply line 162. The load driving circuit 1
The supply of the power supply voltage to the power supply circuit 39 or the like is performed by
7, the power may be supplied directly from the power supply line 162.

The communication circuit 138 performs serial-parallel conversion of the input multiplex communication signal, and provides control signals for the motors 121 to 123 and the lamp 125 in the load 120 to the load drive circuit 139. .
The load drive circuit 139 receives the control signal and controls the operations of the loads 121 to 123 and 125. The load drive circuit 139 may switch a power MOSFET, a relay, or a transistor, for example.

On the other hand, after the detection circuit processes the detection signal from the sensor 124, the detection signal is transmitted to the communication circuit 137.
In the above-described method, the parallel-serial conversion is performed, and the control information is transmitted as control information to the control means 15 on the vehicle body side through the multiplex signal line 16.

According to the first embodiment having the above structure, the module 100 manufactured by, for example, a sub-line is simply assembled to the door 21 in the vehicle assembly line, and the various loads 120 mounted on the door 21 and the control of the vehicle body are controlled. The connection point connector 130 as a connection portion with the multiplex communication line 16 from the means 15 can be easily assembled to the door 2 in a state where the connection point connector 130 is connected to each other, so that the steps in the vehicle assembly line can be omitted and simplified. Thus, a module in a reliable state can be assembled as the module 100 in advance. In addition, even in the assembly of the module 100, since the connection point connector 130 has a multiplex communication function and has individual harnesses 131, 131,.
The intermediate harness between the door-side ECU and each load in the conventional multiplex communication system can be omitted.
In addition to being able to be configured with an extremely small number of parts, the assembling work can be easily performed by drastically reducing the connector connection work. For this reason, even if the number of loads 120 increases due to option setting or addition of a new function, it is possible to easily cope with the increase in the number of parts as much as possible.

As described above, since only the module 100 can be manufactured separately from the manufacture of the door 21,
Failure diagnosis such as operation confirmation of each load can be performed before assembling to the door 21, and even if a failure due to an assembling work defect or the like occurs, it can be dealt with separately from the vehicle assembly line. As an example of such a failure diagnosis, as shown in FIG. 7, the connector 31a of the failure diagnosis device 31 is fitted and connected to the input terminals 134,.
By supplying the pseudo control signal from the, it is possible to confirm the operation of each load 120 and to confirm the continuity.

The connection point connector 130 used in the above-described module 100 has a multiplex communication function constituted by a communication circuit 138 and the like in addition to being used for assembling the module 100 as in the present embodiment. It can be used as an ECU with a built-in multiplex communication function. Therefore, the connection point connector 130 may be used as an ECU for controlling various actuators using multiplex communication of an automobile or the like without being incorporated in the module 100 as in the present embodiment. In this case, since the connection point connector 130 integrally includes individual harnesses 131, 131,.
When used as an ECU, the work of connecting to each load to be controlled can be easily performed and the number of parts can be reduced to make it compact.
