[0042] In addition, in the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "axial direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the axial direction X, the width direction Y, and the height direction Z are substantially orthogonal to each other. The axial direction X typically follows the extending direction of the plurality of electric wires W, the inserting direction of the plurality of electric wires W with respect to the cage 1, the length direction (extending direction) of the cage 1, etc. The width direction Y typically follows the width direction of the cage 1, the thickness direction of the joint connector 50 described later, etc. The height direction Z typically follows the height direction (vertical direction) of the cage 1 and the joint connector 50, etc. In addition, unless otherwise specified, each direction used in the following description is described as the direction in the state where the cage 1 is assembled to the vehicle.

[0043] As Figure 1 shown, the wire harness WH is configured to include, for example, a main line portion W1 extending along the axial direction X and a plurality of branch line portions W2 branched from the main line portion W1.

The main line portion W1 may include, for example, the portion where the largest number of electric wires W in the wire harness WH are bundled, or may include the portion having the largest outer diameter in the wire harness WH. In Figures 1 to 3 order to simplify, the illustration of the plurality of electric wires W constituting the main line portion W1 is simplified.

[0044] The branch line portion W2 is a sub-wire harness portion of the wire harness WH and is formed by a plurality of electric wires W branched from the main line portion W1. A connector 2 connected to the joint connector 50 is provided at each end of the branch line portion W2. A bus bar or the like for connecting the connectors 2 of the plurality of branch line portions W2 to each other is provided in the joint connector 50, and the plurality of branch line portions W2 are electrically connected to each other via the joint connector 50. In addition, in Figure 1 order to simplify, connectors 2 are connected to two of the plurality of connection ports 51 of the joint connector 50, but actually, connectors 2 (branch line portions W2) are connected to the plurality of (six) connection ports 51 respectively.

[0045] The plurality of electric wires W are formed to extend linearly along the axial direction X, for example, and extend with substantially the same diameter in the axial direction X (extending direction).

A pair of side wall portions 13, 15 both extend along a direction orthogonal to the width direction Y and are arranged parallel to each other at intervals in the width direction Y. The side wall portion 13 is provided at one end portion in the width direction Y of the bottom wall portion 18 and constitutes the left end portion of the cage body 10. The side wall portion 15 is provided at the other end portion in the width direction Y of the bottom wall portion 18 and constitutes the right end portion of the cage body 10. The engagement connector 50 is fixedly engaged via a clamping member 55 or the like on the side wall portion 13.

[0054] The cage cover 20 is configured to include, for example, a top wall portion 21, a pair of side wall portions 22, 23, and a pair of mounting piece portions 26 (refer to Figure 2 ). The cage cover 20 is integrally formed, for example, from synthetic resin or the like, with the top wall portion 21, the pair of side wall portions 22, 23, and the pair of mounting piece portions 26. The cage cover 20 has a substantially U-shaped cross section by the top wall portion 21 and the pair of side wall portions 22, 23 that are connected to each other.

[0055] The top wall portion 21 and the pair of side wall portions 22, 23 are structures for partitioning the wiring space portion 25 of the cage cover 20. The wiring space portion 25 is a space portion for inserting and routing the above-mentioned plurality of electric wires W. In a state where the cage cover 20 is in the joining operation position P1 (refer to Figure 1 ), the top wall portion 21 is located on the other side in the height direction Z of the wiring space portion 25, and in a state where the cage cover 20 is in the use position P2 (refer to Figure 2 、 Figure 3 ), the top wall portion 21 is located on one side in the height direction Z of the wiring space portion 25. The top wall portion 21 is formed in a flat plate shape that extends horizontally along the axial direction X.

[0056] Each of the pair of side wall portions 22, 23 extends in a direction orthogonal to the width direction Y and is provided parallel to each other with a space therebetween in the width direction Y. In a state where the cage cover 20 is in the joining operation position P1, the side wall portion 22 is located on one side in the width direction Y of the wiring space portion 25, and in a state where the cage cover 20 is in the use position P2, the side wall portion 22 is located on the other side in the width direction Y of the wiring space portion 25. Further, in a state where the cage cover 20 is in the joining operation position P1, the side wall portion 23 is located on the other side in the width direction Y of the wiring space portion 25, and in a state where the cage cover 20 is in the use position P2, the side wall portion 23 is located on one side in the width direction Y of the wiring space portion 25.

[0057] The pair of mounting piece portions 26 are provided at both ends in the axial direction X of the wiring space portion 25. The pair of mounting piece portions 26 project from both ends in the axial direction X of the top wall portion 21 and the side wall portion 22 toward the side where they are separated from each other along the axial direction X. The pair of mounting piece portions 26 have a substantially L-shaped cross section and cover a part of the outer peripheral surface of the plurality of electric wires W. The pair of mounting piece portions 26 function as a portion around which a bundling member 3 for bundling the plurality of electric wires W is wound. The bundling member 3 can be, for example, a bundling member such as a bundling band, a tape member such as a tape, or other members. The bundling member 3 fixes the plurality of electric wires W to the pair of mounting piece portions 26 by bundling the plurality of electric wires W and the pair of mounting piece portions 26 together.

[0058] Here, in the present embodiment, when the cage cover 20 is in the use position P2 (refer to Figure 3In the state of , the wiring space portion 25 is located at a position overlapping with one side of the mating connector 50 in the height direction Z, and opens toward the other side in the height direction Z to communicate with the internal space portion 16 of the cage body 10. Further, in this state, a surplus length accommodation space portion 29 is provided between the wiring space portion 25 and the mating connector 50, and the surplus length accommodation space portion 29 accommodates a plurality of branch line portions W2 branched from the above-mentioned main line portion W1 and directed toward the mating connector 50.

[0059] The surplus length accommodation space portion 29 is a gap formed between the wiring space portion 25 and the mating connector 50 and extending along the height direction Z. The surplus length accommodation space portion 29 is formed, for example, by a gap between the upper end portion on one side in the height direction Z of the cage body 10 and the mating connector 50, a gap between the lower end portion on the other side in the height direction Z of the cage cover 20 and the main line portion W1 routed in the wiring space portion 25, and the like. In the present embodiment, for example, by fixing the main line portion W1 close to the top wall portion 21 side by using the bundling member 3 wound around the pair of mounting piece portions 26, the surplus length accommodation space portion 29 is ensured between the wiring space portion 25 and the mating connector 50. For example, a plurality of branch line portions W2 having surplus lengths are accommodated in the surplus length accommodation space portion 29 in a bent form.

[0060] Further, in the present embodiment, in the state where the cage cover 20 is in the mating operation position P1 (refer to Figure 1 ), the wiring space portion 25 is located at a position offset in the width direction Y with respect to the mating connector 50, and opens toward the same side in the height direction Z as the connection port 51 of the mating connector 50. Thus, in the present embodiment, by connecting the cage cover 20 to the cage body 10 so as to be rotatable between the mating operation position P1 and the use position P2, the workability of the mating operation at the mating operation position P1 is improved, and the cage 1 used at the use position P2 is configured more compactly.

[0061] As described above, in the cage 1 and the wire harness WH of the present embodiment, in the state where the cage cover 20 is in the mating operation position P1, the wiring space portion 25 can be arranged offset in the width direction Y with respect to the mating connector 50, and in the state where the cage cover 20 is in the use position P2, the wiring space portion 25 can be arranged to overlap with one side of the mating connector 50 in the height direction Z. As a result, the cage 1 and the wire harness WH can improve the workability of the mating operation between the connector 2 and the mating connector 50.

[0062] In addition, in the cage 1 and the wire harness WH of the present embodiment, in a state where the cage cover 20 is in the joining operation position P1, the wiring space portion 25 opens toward one side in the height direction Z that is the same as the connection port 51 of the joining connector 50. According to this structure, the cage 1 and the wire harness WH can, for example, use the cage cover 20 as a wire receiving jig for a plurality of electric wires W on the jig plate during the manufacturing process of the wire harness WH, and thus can further improve the workability of the joining operation.

[0063] In addition, in the cage 1 and the wire harness WH of the present embodiment, there is a slack accommodation space portion 29 formed between the wiring space portion 25 and the joining connector 50 in a state where the cage cover 20 is in the use position P2. In a state where the cage cover 20 is in the use position P2, the main line portion W1 is routed in the wiring space portion 25, and a plurality of branch line portions W2 branching from the main line portion W1 and facing the joining connector 50 are accommodated in the slack accommodation space portion 29. According to this structure, the cage 1 and the wire harness WH can, for example, ensure a space for accommodating a plurality of branch line portions W2 through the slack accommodation space portion 29, and thus can more smoothly accommodate the plurality of branch line portions W2 in a slack and bent form in the slack accommodation space portion 29.

[0064] In addition, in the cage 1 and the wire harness WH of the present embodiment, the cage cover 20 has a pair of mounting piece portions 26 provided at both ends in the axial direction X of the wiring space portion 25 for winding a bundling member 3 for bundling a plurality of electric wires W. According to this structure, the cage 1 and the wire harness WH can, for example, easily fix a plurality of electric wires W to the pair of mounting piece portions 26 by bundling the plurality of electric wires W and the pair of mounting piece portions 26 together with the bundling member 3.

[0065] [Modification Example]

[0066] Figure 4 FIG. 13 is a perspective view of a wire harness WH to which the cage 1A according to the modification example is applied, and is a view in a state where the cage cover 20 is in the joining operation position P1. Figure 4 The shown cage 1A has the same structure as the cage 1 of the above-described embodiment. Therefore, the cage 1A can obtain the same functions and effects as those of the above-described embodiment based on the same structure.

[0067] However, in the present modification example, as shown in FIG. 14, the cage cover 20 is provided with a pair of ribs 27, which is different from the above-described embodiment. The pair of ribs 27 is provided, for example, at both ends in the axial direction X of the side wall portion 22 and protrudes toward the wiring space portion 25 side. In a state where the cage cover 20 is in the joining operation position P1, the pair of ribs 27 is provided at the upper end portion on one side in the height direction Z of the side wall portion 22 to suppress the floating of a plurality of electric wires W. Figure 4 ​

[0068] In addition, a pair of ribs 27 of a connector 2 having a plurality of branch portions W2 (refer to Figure 1 ) has a fitting detection function with the mating connector 50. Specifically, in this modified example, in a state where the connector 2 and the mating connector 50 are semi-fitted, and the cage cover 20 is in the above-described use position P2, the pair of ribs 27 are separated from the bottom wall portion 18 of the cage body 10 toward one side in the height direction Z, and the locking portion 40 of the locking portion 40 and the locked portion 42 of the locked portion 42 cannot be locked. The operator can detect the fitting state of the connector 2 and the mating connector 50 by confirming the gap between the pair of ribs 27 and the bottom wall portion 18.

[0069] In addition, in this modified example, the claw-shaped locking portion 41 of the locking portion 40 is provided on the side of the cage body 10, and the locked portion 42 in the form of a locking hole of the locking portion 40 is provided on the side of the cage cover 20. In addition, in this modified example, a plurality of window portions 28 penetrating the side wall portion 22 in the width direction Y are provided in the cage cover 20.

[0070] As described above, in the cage 1A of this modified example, the cage cover 20 has ribs 27 that protrude toward the wiring space portion 25 side and suppress the floating of the plurality of electric wires W. According to this structure, the cage 1A and the wire harness WH can suppress the floating of the plurality of electric wires W by the ribs 27, and further, in a state where the cage cover 20 is in the use position P2, the plurality of electric wires W can be more appropriately wired in the wiring space portion 25.

[0071] It should be noted that, in the above-described embodiments and modified examples, an example is shown in which a pair of mounting piece portions 26 are provided at both ends in the axial direction X of the cage cover 20, but it is not limited to this example. For example, the mounting piece portion 26 may be provided only at one end in the axial direction X of the cage cover 20, or a pair of mounting piece portions 26 may not be provided at both ends in the axial direction X of the cage cover 20.

[0072] The above shows embodiments and modified examples of the present invention, but the above-described embodiments and modified examples are examples and do not intend to limit the scope of the invention. The above-described embodiments and modified examples can be implemented in various other ways, and various omissions, substitutions, combinations, and changes can be made without departing from the gist of the invention. In addition, each structure, shape, etc. specifications (structure, type, direction, form, size, length, width, thickness, height, quantity, arrangement, position, material, etc.) can be appropriately changed and implemented.
