- the connector pins 17 and 18 are connected to the other printed circuit patterns.
- the terminal 30 is mounted to the cable unit 10 in such a manner that the power conductor portion 10f is laid in the generally flat shaped recess 26f and signal conductor portions 10r are laid in the round recesses 26r. Then the terminal 30 is closed as shown in Fig. 4 and Fig. 6 with the top case half 30a and bottom case half 30b locked in a closed manner by locking member 20, the ends of the connector pins 15, 16, 17 and 18 penetrate the insulation layer 11 and the connector pins 15 and 16 contact to the power supply conductors 1 and 2 respectively and the connector pins 17 and 18 clamp and contact the signal conductors 3 and 4 by their fork shaped ends as shown in Fig. 6.
- the respective projections 14 are fitted in the grooves 12 and 13. In other words, the grooves 12 and 13 can serve to position the connector pins 17 and 18 with respect to the conductors 3 and 4.
