In the protector 1, an outer wall surface (hereinafter referred to as "protector outer wall surface") 1w (fig. 1, 2, 5, and 6) is formed by the outer wall surfaces 10w and 20w of the protector body 10 and the outer cover 20 in an assembled state. In the protector 1 shown here, a part of the bottom wall surface 11a of the protector body 10 between the internal housing chambers 10b and the like also becomes the outer wall surface 10w of the protector body 10. The protector body 10 shown here is provided with a standing wall 16, and the standing wall 16 is disposed between a first outer cover 20A and a second outer cover 20B of the outer covers 20 in an assembled state so as to stand from between the respective inner housing chambers 10B of the bottom wall surface 11a (fig. 1 and 5 to 8). The standing wall 16 extends in the wiring direction of the internal electric wire We1 in each internal housing room 10B, and is disposed facing the outer wall surface 22a of each side wall 22 disposed facing between the first external cover 20A and the second external cover 20B. Thus, in the protector 1, the wall surface of the standing wall 16 also serves as the outer wall surface 10w of the protector body 10. In the protector 1 shown here, the connecting body 23 of the outer cover 20 partially covers the connecting bottom wall surface 13 of the relay chamber 10c from above the second inner cover portion 32. Thus, in the coupling body 23, the wall surface 23a on the lid body 21 side opposite to the second inner cover portion 32 becomes the outer wall surface 20w of the outer cover 20.
The protector 1 has the external electric wire We2 routed along the protector outer wall surface 1 w. Therefore, the protector outer wall surface 1w is provided with the external housing chamber 50, and the external housing chamber 50 houses and routes the external electric wire We2 from the electric wire insertion port 50a (fig. 1 to 3, 5, 6, and 9).

The external housing chamber 50 includes: a bottom wall surface 51 disposed opposite to the wire insertion port 50a with a space; and side wall surfaces 52 that are provided upright from the bottom wall surface 51 toward the wire insertion port 50a and are arranged to face each other with a space therebetween (fig. 3, 5, 6, and 9). That is, the external housing chamber 50 is a space surrounded by the bottom wall surface 51 and the side wall surfaces 52. In the external housing chamber 50, the external electric wire We2 is routed along the wire insertion port 50a, the bottom wall surface 51, and the side wall surfaces 52. The external housing room 50 shown here is provided with 1 in between the respective internal housing rooms 10B (i.e., between the first external cover 20A and the second external cover 20B) on the side of the 2 internal housing rooms 10B with respect to the relay room 10c, and the external electric wires We2 are wired in substantially the same direction as the wiring direction of the respective internal electric wires We 1. The external housing chamber 50 has a wire outlet 50b, and the wire outlet 50b draws out an external wire We2 (fig. 5 and 6) wired in the external housing chamber 50 to the outside.
The bottom wall surface 51 is formed by at least one of the outer wall surfaces 10w, 20w of the protector body 10 and the outer cover 20, respectively. The bottom wall surface 51 shown here is formed by a portion of the bottom wall surface 11a of the protector body 10 between the respective internal storage chambers 10B (between the first outer cover 20A and the second outer cover 20B) and serving as the protector outer wall surface 1w, and a wall surface 23a on the lid body 21 side in the coupling body 23 of the outer cover 20 (fig. 5 and 6). Thereby, the inner cover 30 in the closed position is disposed between the relay chamber 10c and the outer housing chamber 50.
Each side wall surface 52 is formed by at least one of the outer wall surfaces 10w, 20w of the protector body 10 and the outer cover 20. One side wall surface 52 shown here is formed by the outer wall surface 22a of the side wall body 22 of the first outer cover 20A disposed opposite to the second outer cover 20B. The standing wall 16 of the protector body 10 and the side wall body 22 of the second outer cover 20B are used for the other side wall surface 52 shown here. The other side wall surface 52 is formed by a wall surface 16a of the standing wall 16 disposed to face the first outer cover 20A and an outer wall surface 22a of the side wall body 22 of the second outer cover 20B disposed to face the first outer cover 20A (fig. 5 and 6). Here, a portion of the outer wall surface 22a of the side wall body 22 of the second outer cover 20B, which is connected to the wall surface 23a of the coupling body 23 on the lid body 21 side, is used as a part of the other side wall surface 52.
Here, the external housing room 50 includes a wire holding portion 53 (fig. 1, 2, and 4 to 8) that holds the external wire We2 therein. The wire holding portion 53 includes: a pair of cantilevered pieces 53a that are erected from the bottom wall surface 11a of the protector body 10 and are arranged facing each other in the facing direction of the internal housing chambers 10 b; and a pair of locking piece portions 53b that project from the free ends of the respective piece portions 53a toward the other piece portion 53a and are disposed facing each other with a space therebetween (fig. 5 to 8). The external electric wire We2 is inserted between the respective locking piece portions 53b and 53 a. In the wire holding portion 53, the relative movement of the external wire We2 in the facing direction with respect to the protector outer wall surface 1w is restricted by the respective piece portions 53a, and the relative movement of the external wire We2 in the direction opposite to the insertion direction with respect to the protector outer wall surface 1w is restricted by the respective locking piece portions 53 b.
The wire holding portion 53 is provided in 2 places in the external housing chamber 50 (fig. 1, 2, and 4). The combination of the one "piece portion 53a and the locking piece portion" 53B in the one wire holding portion 53 is arranged between the wall surface 16a of the standing wall 16 constituting the other side wall surface 52 and the outer wall surface 22a of the side wall body 22 of the second outer cover 20B (fig. 5 and 6). In the external housing chamber 50 shown here, the other wire holding portion 53 is arranged on the side opposite to the wire drawing port 50b side with respect to the one wire holding portion 53.
The protector outer wall surface 1w shown here is provided with a wire locking portion 60, and the wire locking portion 60 locks relative movement of the external wire We2 drawn out from the wire drawing port 50b to the outside of the external storage compartment 50 toward the wire insertion port 50a (fig. 1, 2, and 4). The wire locking portion 60 has a passage 60a like a through hole in a rectangular parallelepiped shape, and an external wire We2 drawn out from the wire drawing port 50b is inserted through the passage 60 a.
In the protector 1 of the present embodiment, the wiring is performed while the internal electric wires We1 are stored in the respective internal storage chambers 10b, and then the internal cover 30 in the open position is moved to the closed position and locked to the protector body 10 by the locking mechanism 36. In this protector 1, at this time, the wiring path of each internal electric wire We1 in the relay chamber 10c is restricted. That is, in the protector 1 of the present embodiment, the respective internal electric wires We1 can stay in the respective wiring areas 10d by the partition wall 15 of the relay chamber 10c and the inner cover 30. Accordingly, even in the protector 1, the internal electric wires We1 routed in the respective internal storage chambers 10b around the relay chamber 10c can be kept in their positions.
Therefore, in the protector 1, even if the internal electric wires are not fixed to the protector body by fixing members such as jigs and clips as in the conventional case, the respective internal electric wires We1 can stay on the wiring path. This protector 1 can thereby reduce the work time required for wiring the internal electric wire We1 and reduce the number of components. In the protector 1, the outer cover 20 can be assembled to the protector main body 10 without the operator or the like being aware of the floating of the respective inner wires We1 from the inner housing chamber 10b after the inner cover 30 is moved to the closed position. Then, in the protector 1, the external electric wire We2 is wired while being stored in the external storage room 50. As described above, the protector 1 of the present embodiment can improve the assembling workability compared to the conventional one, and can achieve a cost reduction corresponding thereto. In the protector 1 of the present embodiment, the partition wall 15 of the relay chamber 10c and the inner cover 30 can restrict the wiring paths of the internal electric wires We1 and the external electric wires We2, and the internal electric wires We1 and the external electric wires We2 having different wiring paths can be collected. The wire harness WH of the present embodiment is provided with such a protector 1, and thus the effects obtained by the protector 1 can be obtained similarly.
