Two wire insertion ports 31, 31 that serve as inlets or outlets and also serve as outlets through which the electric wire W from the electric wire outlet 20 a is drawn out in the wiring direction are formed in the side wall 30 a of the electric wire protection regulation cover 30. When assembling to a plurality of connectors 10 provided along the cable direction, each wire insertion port 31, 31 can be assembled to the connector 10 without limiting its function as an entrance or exit of the wire W. The restriction cover 30 can be assembled to the plurality of connectors 10 provided along the wiring direction of the electric wires W.

  Further, in the connector unit 1 according to the embodiment of the present invention, the wire protection regulating cover 30 is axially symmetric, and the wire drawing side end 20b, which is the end on the wire drawing port 20a side, has the opening side end 30c and the axis A. Since the two sides of the wire insertion ports 31 and 31 are in the same direction, the direction in which the wire protection restriction cover 30 is attached to the connector housing 20 is not limited. In other words, the wire protection regulation cover 30 may be assembled to the connector housing 20 with either of the two wire insertion openings 31, 31 facing the wire protection regulation cover 30 arranged adjacent to the connector housing 20.

(Modification)
Next, a modified example of the connector unit 1 according to the embodiment of the present invention will be described with reference to FIGS. 9 and 10. FIG. 9 is an exploded perspective view of the connector unit 2 as a modification of the connector unit 1 according to the embodiment of the present invention. 10A and 10B are perspective views of the connector unit 2 in which the wire protection regulation cover 60 is attached to the connector housing 50 in different directions about the axis center.
The connector unit 2 of this modification has a circular cross-sectional outer shape orthogonal to the axis A of the opening side end 60c, and a cross section orthogonal to the axis A so that the wire lead-out side end 20b can be fitted to the opening side end 60c. It differs from the connector unit 1 of the embodiment in that the outer shape is circular.
Other configurations are the same as those in the embodiment, and the same components as those in the embodiment are denoted by the same reference numerals.

  The connector unit 2 has a shaft center rotation locking portion 70 that locks the wire protection regulation cover 60 and the connector housing 50 in a plurality of directions rotated about the wire protection regulation cover 60 with respect to the connector housing 50. .

Therefore, the wire protection regulation cover 60 is fixed to the connector housing 50 each time the wire protection regulation cover 60 is rotated at a predetermined angle about the axis center with respect to the connector housing 50.
For this reason, as shown in FIG. 10, the direction in which the electric wires are routed can be changed in a direction in which the directions of the two electric wire insertion openings 61 and 61 are rotated at a predetermined angle about the axis.

  The connector unit 2 according to this modification has the same effects as the connector unit 1 of the embodiment, and the outer shape of the cross section perpendicular to the axis A of the opening side end 30c is circular, and the wire drawing side end 20b is Since the cross-sectional outer shape orthogonal to the axis A that can be fitted to the opening side end 30c is circular, the wire protection regulation cover 30 rotates about the axis with a degree of freedom in the rotation angle with respect to the connector housing 20. Can do.

  In addition, although the connector unit 1 which concerns on the Example of this invention illustrated what the electric wire protection control cover 30 was axisymmetric, it should just have comprised the bottomed cylindrical shape not only this. For example, the cross-sectional outer shape may be rectangular.
