[0011] Specific embodiments of the present invention will be described below with reference to the respective figures.

[0012] Figure 1 is a perspective view of a wire harness provided with a connector holder 1 according to an embodiment of the present invention. Figure 2 is a perspective view of the holder body 20 shown in Figure 1. Figure 3 is a perspective view of the cover as shown in Figure 1. Figure 4 is an enlarged view showing the vicinity of the opening 40 which is an example of the first opening. Figure 5 is an enlarged view showing the vicinity of the upper cover portion 45 which is an example of the inclined surface. Figure 6 is an enlarged view showing the vicinity of the terminal of the wire bundle W1 in the vehicle-mounted state. Figure 7 is a partially enlarged view of the cover 100 according to the reference example. Hereinafter, for the sake of convenience of explanation, as shown in Figures 1 to 7, "front", "rear", "upper", "lower", "left", "right", "front-rear direction", "left-right direction" and "up-down direction" are defined. The "front-rear direction", "left-right direction" and "up-down direction" are orthogonal to each other. In addition, in the present embodiment, the up-down direction shown in Figures 1 to 6 coincides with the up-down direction in the state where the wire harness is routed to the vehicle which is the mounting target and the connector holder 1 is attached to the vehicle body, that is, in the vehicle-mounted state.

[0013] <Wire harness> The wire harness shown in FIG. 1 includes a wire bundle W formed by bundling a plurality of wire bundles W1, connectors C attached to the terminals of each wire bundle W1, and a connector holder 1 that holds the plurality of connectors C. The wire bundle W1 is formed by bundling a plurality of electric wires, and each electric wire has a conductive core wire and an insulating coating that covers the outer periphery of the core wire.

[0014] The connector C includes terminals attached to the terminals of each electric wire constituting the wire bundle W1, and a connector housing that houses the terminals in a cavity. The terminal is made of a conductive metal plate and is electrically connected to the core wire by crimping or the like. This connector housing is formed in a substantially rectangular parallelepiped shape from an insulating resin, and the cavity extends in the left-right direction.

[0015] <Connector holder 1> The connector holder 1 is formed of an insulating resin, attached to the vehicle body, and fixes the connector C of the wire harness routed in the vehicle. The connector holder 1 includes a holder body 20 shown in FIG. 2 and a cover 10 shown in FIG. 3. In the connector holder 1, with the connectors C attached to the terminals of each of the plurality of wire bundles W1 housed in the respective connector accommodation spaces of the holder body 20, the cover 10 covers the front surface of the holder body 20 and fits onto the holder body 20. As an example, the connector holder 1 is disposed at a position below the instrument panel, that is, at the feet of the driver and the front passenger. Therefore, for example, when a passenger spills tea, there is a risk that water will splash onto the cover 10. As will be described later, in the connector holder 1 of the present embodiment, by providing an opening 40 in the cover 10, even when water splashes onto the cover 10, it is possible to prevent the water repelled by the cover 10 from scattering to the surroundings.

[0016] <Holder body 20> The holder body 20 has a first base 21 and a second base 31, and holds a connector C in which terminals attached to an electric wire are mounted inside a cavity. The holder body 20 is joined by the first base 21 and the second base 31 being positioned in the left-right direction and locking together. The holder body 20 holds multiple connectors C on its front surface.

[0017] As shown in Figure 2, the first base 21 has a flat plate portion 22, an upper wall 23, a lower wall 24, a right side wall 25A, two left side walls 25B, a plurality of partition walls 26, a plurality of partition walls 27, and a partition wall 28. The flat plate portion 22 extends in the vertical and horizontal directions and has a substantially rectangular shape. The upper wall 23 and the lower wall 24 are substantially rectangular flat plates that extend forward from the upper and lower edges of the flat plate portion 22, respectively. The upper right surface of the upper wall 23 is provided with a locking portion 23a to which the locking portion 11a of the cover 10, which will be described later, is locked. On the left side of the upper wall 23, there is a wire insertion opening 231 that is open from the front. The lower surface of the lower wall 24 is provided with a mounting portion 241 for fixing the connector holder 1 to the vehicle body, and a locking portion 242 to which the locking portion 11c of the cover 10 is locked. The right side wall 25A is a roughly rectangular flat plate extending forward from the right edge of the flat plate portion 22. The left side wall 25B is a small rectangular piece extending forward near the upper and lower ends of the left edge of the flat plate portion 22.

[0018] Partition wall 26 extends in the left-right and front-back directions and is provided across the left side of the right side wall 25A and the front surface of the flat plate section 22. Partition wall 27 extends vertically on the front surface of the flat plate section 22 and is provided to connect the left ends of the two partition walls 26 to each other. Partition wall 27 has a substantially U-shape when viewed in the left-right direction. Partition wall 28 extends vertically in continuity with the lower end of the lower partition wall 27. The flat plate section 22, the multiple partition walls 26, the multiple partition walls 27 and partition wall 28 define multiple connector housing spaces in the right-side region of the first base 21. The first and second partition walls 26 from the top each have locking claws 26a and 26b projecting upward and downward, respectively, for locking connectors C. Partition wall 28 has a locking claw 28a projecting to the right for locking connectors C. In other words, the multiple partitions 26, 27, and 28 that hold multiple connectors C in the right-side region of the first base 21 are examples of connector holding parts.

[0019] In the area to the left of the partition walls 27 and 28 in the first base 21, a bundle of wires W, with each connector C connected to its terminal, is arranged. The left-side area of ​​the first base 21, that is, the area to the left of the partition walls 27 and 28, is an example of a housing section for accommodating the bundle of wires W. The bundle of wires W arranged in the first base 21 is pulled upward through the wire insertion opening 231.

[0020] The second base 31 has a flat rear wall 32 and a front wall 35 spaced apart from each other, and an upper wall 33 and a lower wall 34 that connect the rear wall 32 and the front wall 35 at their upper and lower edges. The rear wall 32 has protruding portions that project to the left at its upper and lower edges. The upper wall 33 and the lower wall 34 are formed to extend to the left end of each protruding portion. The upper surface of the upper wall 33 is provided with a locking portion 33a into which the locking portion 11b of the cover 10 is locked. The lower surface of the lower wall 34 is provided with a locking portion 34a into which the locking portion 11d of the cover 10 is locked. The second base 31 is configured to accommodate a connector between the rear wall 32 and the front wall 35.

[0021] On the front surface of the front wall 35, two connector mounting sections 36 and 37 are provided, spaced apart in the vertical direction, to which connectors C are attached. The connector mounting sections 36 and 37 are hollow rectangular tubes configured to accommodate the connectors C, and the connectors C are locked in place by locking claws. Above the connector mounting section 36, an upper cover section 45 is provided, which is erected forward from the front wall 35. The upper cover section 45 is a rectangular flat plate having an inclined surface that slopes vertically from top to bottom when the connector holder 1 is attached to the vehicle body to which it is mounted. An upward-extending vertical wall 451 is provided at the front edge of the upper cover section 45. The left end of the upper cover section 45 extends to the left of the left end face of the connector C mounted on the connector mounting section 36, preventing water from splashing onto this connector C and the connector C mounted on the lower connector mounting section 37 from above. Furthermore, the upper cover portion 45 functions as a rib that reinforces the connector mounting portion 36.

[0022] The second base 31 is connected to the first base 21 such that the right edge of the rear wall 32 abuts against the left edge of the flat plate portion 22 of the first base 21.

[0023] <Cover 10> As shown in Figure 3, the cover 10 has a flat plate portion 11 that extends vertically and horizontally and has a roughly C-shape in a plan view when viewed in the front-to-back direction, and a bulging portion 12 that protrudes forward from the flat plate portion 11. The cover 10 covers a part of the holder body 20. When the cover 10 is fitted onto the holder body 20, an internal space S is formed between the cover 10 and the holder body 20, and the wire bundle W and the multiple connectors C are housed in the internal space S.

[0024] The cover 10 has a plurality of openings 40 that connect the external space and the internal space S. The external space refers to the space outside the connector holder 1, located on the opposite side of the cover 10 from the holder body 20. The opening 40 is an example of a first opening. The opening 40 is provided above the bulging portion 12.

[0025] The flat plate portion 11 has a first portion 111 that is substantially rectangular in shape and extends in the vertical and horizontal directions, a second portion 112 that extends to the left at the upper end of the first portion 111, and a third portion 113 that extends to the left at the lower end of the first portion 111. The second portion 112 has a hypotenuse that extends diagonally upward from the middle portion in the horizontal direction toward the left end. The third portion 113 has a hypotenuse that extends diagonally downward from the middle portion in the horizontal direction toward the left end. The flat plate portion 11 has straight edges on both the upper and lower edges and the right edge. Locking portions 11b and 11a are provided at both the left and right ends of the upper edge of the flat plate portion 11, and locking portions 11d and 11c are provided at both the left and right ends of the lower edge of the flat plate portion 11.

[0026] The bulging portion 12 has a flat main body portion 12A extending to the left front from the left edge of the first portion 111 of the flat plate portion 11, a bottom portion 14 connecting from the lower end edge of the main body portion 12A to the upper edge of the third portion 113 of the flat plate portion 11, and a plurality of connecting pieces 13. The plurality of connecting pieces 13 each extend from the rear surface of the upper end of the main body portion 12A to the front surface of the lower end of the second portion 112, and are arranged spaced apart from each other in the left-right direction.

[0027] Each window section, formed between the second portion 112 of the flat plate portion 11 and the main body portion 12A of the bulging portion 12 and partitioned by a plurality of connecting pieces 13, is an opening 40, and the internal space S and the external space are in communication through the opening 40. Therefore, if water is poured onto the front surface of the cover 10 from above, the water is drawn into the internal space S inside the cover 10 through the opening 40. Thus, when water is poured onto the cover 10, it is possible to prevent the water repelled by the cover 10 from scattering into the surroundings.

[0028] As shown in Figure 1, pilot holes 42 and 43, which are examples of drainage holes, are formed at the lower end of the cover 10 between it and the holder body 20. Pilot hole 42 is an opening provided around the locking portion 11c at the lower end of the cover 10. Pilot hole 43 is a rectangular opening formed by recessing a part of the lower end of the cover 10 upwards. Pilot hole 43 is provided at the position of the fixing portion for fixing the connector holder 1 to the mounting object, which extends downward from the lower wall 24 of the first base 21. By providing pilot holes 42 and 43 at the lower end of the cover 10, water in the internal space S can be discharged to the outside through the pilot holes 42 and 43. Therefore, it is possible to prevent water from accumulating in the internal space S of the connector holder 1.

[0029] Each of the locking portions 11a, 11b, 11c, and 11d of the flat plate portion 11 locks onto each of the receiving portions 23a, 33a, 242, and 34a provided on the holder body 20, thereby fitting the cover 10 to the holder body 20 and integrating it. When the cover 10 is attached to the holder body 20, the bulging portion 12 functions as a wire cover portion that covers the housing portion that houses the branching portion of the wire bundle W housed in the internal space S, i.e., the portion where the main line branches off into branch lines, and the multiple branch lines to which connectors C are attached at each end. In this state, the first portion 111 of the flat plate portion 11 functions as a connector cover portion that covers the housing portion that holds the multiple connectors C.

[0030] <Wire harness manufacturing process> A wire harness equipped with the connector holder 1 configured as described above is manufactured as follows, as an example. First, a wire bundle W is prepared, which has connectors C and other connectors, with terminals attached to the wires mounted inside the cavities. Next, each connector C attached to each end of the wire bundle W is placed in the connector housing spaces in the right-side region of the first base 21, and is locked to the locking claws 26a, 26b, and 28a of the partition walls 26 and 28 to be held by the first base 21. The other connectors of the wire bundle W are placed in the connector mounting parts 36, 37, etc. of the second base 31 and are held by the second base 31. Next, the first base 21 and the second base 31 are placed side by side in the left-right direction, brought close to each other, and locked together to form a single holder body 20. Next, the wire bundle W is placed on the front of the holder body 20 such that the branching section is located in the left region of the first base 21, the main wire extends upward from the wire insertion opening 231, and the wire is bent and extends upward at a point below the terminal (see Figure 6). The cover 10 is placed on the front side of the holder body 20 on which the wire bundle W is placed, and the cover 10 is assembled to the holder body 20 by locking the locking parts 11a, 11b, 11c, and 11d of the flat plate section 11 to the locking parts 23a, 33a, 242, and 34a provided on the holder body 20, thereby manufacturing the wire harness (see Figure 1).

[0031] The manufactured wire harness is routed to the vehicle, and the connector holder 1 is fixed to the vehicle body as shown in Figure 1. In the vehicle-mounted state shown in Figure 1, if water splashes onto the front of the cover 10 from above, the water falls in the direction indicated by arrow Y1 in Figure 4 and is taken into the internal space S inside the cover 10 through the opening 40. Also, water from above falls in the direction indicated by arrow Y2 in Figure 5, hits the upper surface of the upper cover portion 45, flows along the upper surface of the upper cover portion 45 in the direction indicated by arrow Y3 in Figure 5, and is taken into the internal space S inside the cover 10 through the opening 41. The water taken into the internal space S is then discharged to the outside space through the lower holes 42 and 43. In the vehicle-mounted state, as shown in Figure 6, near the connection point between the electric wire and the connector C, the electric wire is bent at a point where it is below the terminal and extends upward. Therefore, water that descends from above along the wire bundle W1 in the direction indicated by arrow Y4 does not move upward from the bend. This prevents water from splashing onto the terminal. Therefore, it does not impair conductivity between the terminal and the wire.

[0032] <Advantages of the Embodiment> As described above, the connector holder 1 of this embodiment has an opening 40 in the cover 10, which allows water to be drawn into the internal space S inside the cover 10 through the opening 40. Therefore, it is possible to prevent water repelled by the cover 10 from splashing into the surroundings. In addition, since the opening 40 is provided in the wire cover portion (bulging portion 12) and not in the connector cover portion (first portion 111), it is possible to prevent water droplets from adhering to the connection portion between the terminal mounted in the connector cavity and the wire, which could cause a short circuit or corrosion of the connection portion.

[0033] Here, instead of the cover 10 of this embodiment, we consider a connector holder having the cover 100 of the reference example shown in Figure 7. In the reference example, the cover 100 has the upper part of the bulging portion 12 covered by the cover wall 101 and does not have an opening. Therefore, water falling from above in the direction indicated by arrow Y5 will hit the cover wall 101 and splash outwards, i.e., in the directions indicated by arrows Y6, Y7, and Y8, potentially impairing the function of surrounding electronic components, etc. In contrast, the connector holder 1 of this embodiment, as described above, can prevent water repelled by the cover 10 from splashing outwards, thus preventing malfunctions in surrounding components.

[0034] Furthermore, the connector holder 1 of this embodiment has an upper cover portion 45 and an opening 41, and the inclined surface of the upper cover portion 45 can guide water to the opening 41, thereby effectively preventing water from splashing. In addition, the connector holder 1 of this embodiment has lower holes 42 and 43, so that water taken into the internal space S from the external space is discharged through the lower holes 42 and 43, thereby preventing water from accumulating in the internal space S inside the connector holder 1.

[0035] Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, numerical values, form, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve the present invention. For example, in the above embodiment, an inclined surface that slopes from the top vertically downward when mounted on a vehicle was provided on the holder body 20 as an upper cover portion 45, but this inclined surface may be provided on the cover, or on both the cover and the holder body. Also, in the above embodiment, drainage holes for draining water from the internal space to the external space were provided on the cover 10 as lower holes 42 and 43, but they may be provided on the holder body, or on both the cover and the holder body.
