Next, the cable side housing 17 is fitted to the board side housing 16. First, the shaft portion 4 is fitted with the cable side housing 17 standing upright.
2 and the shaft portion 26 are fitted into the bearing recess 21 and the bearing portion 46 of the board-side housing 16, respectively.
7 (see FIGS. 2 and 4). In this state, since the cable-side shield cover 30 and the board-side shield cover 19 are connected via the shaft portion 26 and the bearing portion 46, the conductor 15 exposed from the shield layer is connected to the circuit board via the terminal fitting 11. The conductive path leading to the circuit is shielded by the conductive member for shielding, the cable-side shield cover 30 and the board-side shield cover 19. Next, from this state, the cable side housing 17 is rotated and displaced so as to be tilted. Then, each of the conductors 15 positioned in the positioning groove 32 abuts against the corresponding arm portion 11B of the terminal fitting 11 at a predetermined contact pressure from above, so that the conductor 15 is electrically connected to the circuit on the circuit board. (See FIGS. 1 and 5). When the housings 16 and 17 are fitted to each other, the lock claws 43 are engaged with the lock protrusions 22, so that the housings 16 and 17 are engaged.

In addition, there is no need for the conductor 15 to be displaced in its length direction. further,
Since the holding groove 33 and the pressing surface 40 that hold the conductor 15 are not perpendicular to the rotation direction of the pressing member 29 but are inclined, the conductor 15 moves between the positioning member 28 and the pressing member 29. When sandwiched, the pressing surface 40 rubs the conductor 15 in the direction of its tip. Therefore, there is no possibility that the conductor 15 is loosened, and a favorable contact state with the terminal fitting 11 is ensured.

The pressing member 29 is provided with a positioning member 28.
, There is no possibility of displacement when the holding member 29 is displaced from the release position to the holding position, and the operability is excellent. Further, when the holding member 29 is rotated to the holding position to hold the conductor 15, the holding member 29 is positioned on the positioning member 28.
As a result, the conductor 15 is pressed in a direction crossing the length direction, so that the conductor 15 does not need to be displaced in the length direction. Further, since the holding groove 33 and the pressing surface 40 that hold the conductor 15 are not perpendicular to the rotation direction of the pressing member 29 but are inclined, the conductor 15 is positioned between the positioning member 28 and the pressing member 29. When sandwiched between them, the pressing surface 40 rubs the conductor 15 in the direction of its tip. Therefore, there is no possibility that the conductor 15 is loosened, and a favorable contact state with the terminal fitting 11 is ensured.
