  Joint connectors are used not only for connecting electric wires to each other but also for connecting electronic components to the ends of electric wires. For example, when the electric wire is a signal transmission line (such as a transmission line for multiplex communication), it is necessary to connect a terminating electronic component (such as a resistor or a capacitor) to an end of the pair of electric wires. Conventionally, in such a case, an electronic component unit having a terminating function is assembled to the joint connector. Conventionally, however, a structure in which one set of electronic component units is assembled to one joint connector is used, so when multiple sets of electronic component units are required, it is necessary to use multiple joint connectors and attach the electronic component units to each. There is. As a result, there is a problem that not only takes up much space but also increases the number of times of assembling to the vehicle, resulting in poor working efficiency.

When the flat housing 16 and the flat housing 34 are stacked, the upper-layer locking projections 44 and the lower-layer locking holes are engaged, and the upper and lower layers are united.

  The connection circuit side connector 12 is the same as that shown in FIG. That is, the connection member 20 having the male terminals 26 corresponding to the female terminals 30 and 36 erected on the circuit board 24 on which a predetermined connection pattern is formed is incorporated into the case 18 for receiving the electric wire side connector 10, It is covered with a cover 22.

  When the electric wire side connector 10 and the connection circuit side connector 12 configured as described above are fitted, the female terminal 30-male terminal 26-circuit board 24-male terminal 26- The resistance element 40 and the capacitor 42 are connected via the female terminal 36. The electric wires 32 other than the signal transmission lines are connected to a predetermined connection pattern via the female terminals 30-the male terminals 26-the circuit board 24-the male terminals 26-the female terminals 30.

The circuit board 24 of the connection member 20 forms a pair of connection patterns 50A and 50B in a meandering shape (in this case, two U-turn portions are formed) using the area of eight intermediate layers, and increases the number of nodes. It is something that can be taken. A pair of male terminals 26 surrounded by a thick solid line constitute one node 60. The location where the ground pattern 56 and the land pattern 58 are provided is the same as in FIG. With this configuration, a total of 22 nodes can be obtained. However, only two sets of termination electronic components (not shown) can be mounted.
