Technical problem to be solved by the invention
However, in the electrical connection box, the electric wire is fixed to the electric wire drawing structure by winding a tape around the electric wire drawn out from the drawing port side of the electric wire drawing structure and the electric wire drawn out from the drawing port. Therefore, a tape winding region for winding the tape in the circumferential direction is set on the lead-out opening side of the wire lead-out structure. Here, in the variable portion, the lead-out opening side is present in the tape winding region, and the outer wall surface side in the tape winding region is used as the wound portion of the tape. However, in the variable portion, the opening area of the draw-out opening is reduced as the tape is poured, and accordingly, the portion existing in the tape winding region is reduced, and the wound portion of the tape is reduced. In other words, in the conventional electrical connection box, the smaller the opening area of the adjusted lead-out opening, the more the wound portion of the tape in the tape winding region decreases.

Here, preferably, the 1 st piece and the 2 nd piece each have a flat plate portion disposed on the same plane, and the 2 nd hinge portion is formed such that: the flat plate portion of the 2 nd sheet is inclined with respect to the flat plate portion of the 1 st sheet on the same plane toward the opposite side of the internal space of the wire lead-out structure.
In addition, it is preferable that the 1 st hinge part is formed such that a plane of the flat plate part of the 1 st sheet body is along the cylinder axis direction when an opening area of the adjusted drawing port is the maximum.

Detailed Description
Hereinafter, embodiments of an electrical connection box and a wire harness according to the present invention will be described in detail with reference to the drawings. The invention is not limited to the embodiment.
[ embodiment ]
One embodiment of an electrical connection box and a wire harness according to the present invention will be described with reference to fig. 1 to 8.
The electrical connection box 1 of the present embodiment includes a housing 10 that houses: an electronic component EP; and electric wires (power supply lines, signal lines, etc.) We (fig. 1 and 2) electrically connected to the electronic components EP. The electric connection box 1 electrically connects an object to be connected (not shown) to the electronic component EP via an electric wire We. In the electrical connection box 1, the electric wire We is electrically connected to the electronic component EP inside the housing 10, and the electronic component EP is electrically connected to the connection object via the electric wire We led from the inside of the housing 10 to the outside. The electrical connection box 1, together with the electronic component EP and the electric wire We, constitutes a wire harness WH.
Here, the electronic component EP refers to, for example, a circuit protection component such as a relay or a fuse, a connector, a terminal fitting, and the like. Here, an electronic device such as a circuit board or an electronic control unit (so-called ECU) is considered to be one embodiment of the electronic component EP. The connection object refers to a power source such as a secondary battery, a load such as an electric device (an actuator, etc.), a sensor, and the like. In the electrical junction box 1, for example, a certain electric wire We is electrically connected to a power source, and another electric wire We is electrically connected to a load, and the power source and the load are electrically connected via an electronic component EP.
The frame 10 is formed of an insulating material such as a synthetic resin. The housing 10 has a housing chamber 10a (fig. 2) that houses the electronic component EP and the electric wire We. The illustrated housing 10 is a housing box (fig. 1 and 2) in which a plurality of housing members (a 1 st housing member 11, a 2 nd housing member 12, and a 3 rd housing member 13) are assembled with each other. The 1 st frame member 11 is a cylindrical member having both ends open, and is a so-called frame (fig. 2). In the housing 10, a housing chamber 10a is formed inside the 1 st housing member 11. The 2 nd frame member 12 is a cover member that closes one opening of the 1 st frame member 11, and is a so-called bottom cover (fig. 2). The 3 rd frame member 13 is a lid member that closes the other opening of the 1 st frame member 11, and is a so-called top lid (fig. 2).
In this housing 10, one end sides of the electronic components EP and the electric wires We are housed in the housing chamber 10a inside, and the other end sides of the electric wires We are drawn out from the inside to the outside. Thus, the housing 10 has a cylindrical wire lead-out structure 20 (fig. 2 to 6) that guides the wire We and leads the wire to the outside from the lead-out opening 20 a. In the electrical junction box 1, the electric wire We is fixed to the electric wire lead-out structure 20 by winding the tape 30 around the electric wire lead-out structure 20 and the electric wire We led out from the lead-out opening 20a (fig. 1). In the drawing, a plurality of wires We are bundled together to form a structure.
The wire drawing structure 20 is a cylindrical body provided in a protruding state on the housing 10, and draws the wire We in the cylindrical axis direction. The wire drawing structure 20 has an opening at one end in the cylindrical axis direction communicating with the inside of the housing 10, and an opening at the other end in the cylindrical axis direction serving as a drawing port 20 a. The wire drawing structure 20 has a tape winding region Tp (fig. 6) for winding the tape 30 in the circumferential direction on the drawing port 20a side.
The wire lead-out structure 20 is formed so that the opening area of the lead-out opening 20a can be adjusted according to the wire diameter and the number of wires We. Therefore, a part of the wire drawing structure 20 in the circumferential direction is formed as the variable blade body 20A, and the variable blade body 20A can adjust the opening area of the drawing port 20A in accordance with the wire diameter and the number of the wires We drawn from the drawing port 20A (fig. 3 to 6). The exemplary wire drawing structure 20 is formed in a square tube shape. In the wire drawing structure 20, the variable sheet body 20A is provided on 1 of 4 wall portions thereof, and the remaining portion excluding the variable sheet body 20A becomes the main body 20B (fig. 3 to 6). In the wire drawing structure 20, the drawing port 20A side of the variable blade body 20A and the drawing port 20A side of the main body 20B are set as a tape winding region Tp, and the outer wall surface side of the variable blade body 20A and the outer wall surface side of the main body 20B in the tape winding region Tp become wound portions where the tape 30 is wound.
The variable sheet body 20A has: a 1 st sheet body 21 having a base portion on the inner side of the frame body 10 in the cylinder axis direction of the wire drawing structure 20; the 2 nd blade 22 is disposed closer to the extraction opening 20a than the 1 st blade 21 in the cylinder axis direction (fig. 3, 4, 6, and 7). In the variable blade body 20A, the 1 st blade body 21 is inclined from the base toward the internal space of the wire drawing structure 20 with respect to the main body 20B, and the 2 nd blade body 22 is inclined from the base toward the 1 st blade body 21 with respect to the 1 st blade body 21 toward the opposite side from the internal space of the wire drawing structure 20. In the wire drawing structure 20, the opening area of the drawing port 20a is adjusted according to the respective tilt positions of the 1 st blade 21 and the 2 nd blade 22. Thus, the variable sheet body 20A has: a 1 st hinge part 23 for tilting the 1 st sheet body 21 toward the inner space of the wire drawing structure 20 at the base side of the 1 st sheet body 21 (fig. 4 and 7); and a 2 nd hinge part 24 for connecting the 1 st sheet 21 and the 2 nd sheet 22, and tilting the 2 nd sheet 22 relative to the 1 st sheet 21 to the opposite side of the internal space of the wire drawing structure 20 (fig. 3, 4, 6, and 7).
For example, the wire drawing structure 20 is formed so that the opening area of the drawing port 20a is maximized when the 1 st blade 21 is not tilted with respect to the main body 20B and the 2 nd blade 22 is not tilted with respect to the 1 st blade 21. The wire drawing structure 20 is formed so that the opening area of the drawing port 20a is minimized when the 1 st blade 21 is inclined at the maximum inclination angle with respect to the main body 20B and the 2 nd blade 22 is inclined at the maximum inclination angle with respect to the 1 st blade 21.
The variable sheet body 20A is formed such that: regardless of the size of the opening area of the adjusted drawing port 20a, the 2 nd sheet 22 is present in the tape winding region Tp, and the outer wall surface side of the 2 nd sheet 22 in the tape winding region Tp becomes the wound portion of the tape 30. Thus, in the wire drawing structure 20, the wound portion of the tape 30 in the tape winding region Tp can be suppressed from being reduced.
Specifically, the 1 st plate 21 and the 2 nd plate 22 in this example are formed to have flat plate portions 21a and 22a (fig. 3, 4, 6, and 7) respectively arranged on the same plane. The 1 st piece 21 and the 2 nd piece 22 form the flat plate portions 21a and 22a in a rectangular shape, respectively. The 1 st hinge part 23 is connected to the 1 st side part 21a on the base side of the flat plate part 21a of the 1 st sheet body 211The 2 nd hinge part 24 is connected to the 1 st side part 21a1The 2 nd side 21a arranged opposite to each other2(FIG. 7). In addition, the 2 nd hinge part 24 is connected to the 2 nd side part 21a of the 1 st sheet body 21 with respect to the flat plate part 22a of the 2 nd sheet body 222The 1 st side 22a arranged opposite to each other1By the 1 st side 22a1The 2 nd side part 22a arranged oppositely2As a part of the peripheral edge of the extraction port 20a (fig. 7). The 1 st hinge part 23 and the 2 nd hinge part 24 use a living hinge.
The 1 st sheet 21 is disposed at the 3 rd side 21a facing each other3And the 4 th side 21a4Each of the side walls 21b and 21c (fig. 3, 4, and 7) is provided upright on the internal space side of the wire drawing structure 20. Thus, the 1 st sheet 21 can prevent the electric wire We placed on the flat plate portion 21a from passing through the 3 rd side portion 21a3The 4 th side 21a4And (4) extending. In addition, the 2 nd sheet 22 of this example is disposed at the 3 rd side 22a facing each other3And the 4 th side 22a4Each of the side walls 22b and 22c (fig. 3, 4, and 7) is provided upright on the internal space side of the wire drawing structure 20. This 2 nd sheet body 22 can thereby prevent the electric wire We placed on the flat plate portion 22a from passing through the 3 rd side portion 22a3The 4 th side 22a4And (4) extending.
The first hinge portion 23 of this example is formed such that the plane of the flat plate portion 21a of the first sheet 21 is along the cylindrical axial direction of the wire drawing structure 20 when the opening area of the regulated drawing port 20a is maximum (fig. 8). That is, the 1 st hinge part 23 of the example is formed so that the 1 st sheet body 21 does not fall down to the opposite side of the internal space of the electric wire lead-out structure 20 when the plane of the flat plate part 21a is located in the direction along the cylinder axis of the electric wire lead-out structure 20.
In the wire leading structure 20, the opening area of the leading port 20a is maximized at a position where the respective planes of the flat plate portion 21a of the 1 st blade 21 and the flat plate portion 22a of the 2 nd blade 22 are located along the cylindrical axis direction of the wire leading structure 20 (fig. 8). In the wire drawing structure 20, the opening area of the drawing port 20a is further increased by tilting the 2 nd blade 22 toward the opposite side of the internal space of the wire drawing structure 20 with respect to the 1 st blade 21 at this time. However, since the diameter and the number of the electric wires We that can be drawn out from the drawing port 20a at this time are determined by the 1 st blade 21, the opening area of the drawing port 20a is maximized at a position where the flat plate portion 21a of the 1 st blade 21 and the flat plate portion 22a of the 2 nd blade 22 are located along the cylindrical axis direction of the electric wire drawing structure 20.
The 2 nd hinge portion 24 is formed as follows: at least the flat plate portion 22a of the 2 nd sheet member 22 is inclined to the flat plate portion 21a of the 1 st sheet member 21 on the same plane toward the opposite side of the internal space of the wire lead-out structure 20. The 2 nd hinge portion 24 of this example is formed by: the flat plate portion 22a of the 2 nd sheet member 22 does not fall toward the inner space of the wire lead-out structure 20 with respect to the flat plate portion 21a of the 1 st sheet member 21 on the same plane.
In the wire leading structure 20, when the flat plate portion 21a of the 1 st blade 21 is inclined at the maximum angle of inclination with respect to the cylinder axis direction of the wire leading structure 20 and the flat plate portion 22a of the 2 nd blade 22 is inclined at the maximum angle of inclination with respect to the flat plate portion 21a of the 1 st blade 21, the opening area of the leading port 20a is minimized (fig. 9).
The main body 20B has: a rectangular flat plate portion 26 having one side serving as a peripheral edge portion of the lead-out opening 20 a; and 2 side wall portions 27 (fig. 3 to 5) each serving as a peripheral edge portion of the lead-out opening 20 a. In the main body 20B, side wall portions 27 are provided upright in the same direction from 2 side portions of the flat plate portion 26 which are disposed to face each other. The variable sheet body 20A is disposed opposite to the flat plate portion 26. The main body 20B has a coupling portion 28, and the coupling portion 28 is disposed to face the flat plate portion 26 and couples the flat plate portion 22a of the 2 nd sheet body 22 via the 1 st hinge portion 23 (fig. 4 and 7).
A1 st inclined side portion 27a is formed at a peripheral edge portion of each side wall portion 27, and when the flat plate portion 21a of the 1 st sheet member 21 is inclined at a maximum tilt angle with respect to the cylindrical axial direction of the wire lead-out structure 20, the 1 st inclined side portion 27a and a 3 rd side portion 21a of the flat plate portion 21a3And the 4 th side 21a4Are arranged to face each other and are inclined at the same angle as the flat plate portion 21a with respect to the cylindrical axial direction of the wire drawing structure 20 (fig. 3, 4, and 6). Further, a 2 nd inclined side portion 27b is formed at a peripheral edge portion of each of the side wall portions 27, and when the flat plate portion 21a of the 1 st blade body 21 is inclined at the maximum tilt angle with respect to the cylindrical axial direction of the electric wire lead-out structure 20 and the flat plate portion 22a of the 2 nd blade body 22 is inclined at the maximum tilt angle with respect to the flat plate portion 21a of the 1 st blade body 21, the 2 nd inclined side portion 27b and the 3 rd side portion 22a of the flat plate portion 22a3And the 4 th side 22a4Are arranged to face each other and are inclined at the same angle as the flat plate portion 22a with respect to the cylindrical axial direction of the wire drawing structure 20 (fig. 3, 4, and 6). In other words, at the peripheral edge of each side wall portion 27, there are formed: a 1 st inclined side 27a, the 1 st inclined side 27a matching with the inclination of the 1 st sheet 21 when the opening area of the lead-out opening 20a is minimum; and a 2 nd inclined side portion 27b, the 2 nd inclined side portion 27b is matched with the inclination of the 2 nd sheet body 22 when the opening area of the leading-out opening 20a is minimum.
In the exemplary wire drawing structure 20, a band winding region Tp is defined between the boundary portion from the drawing port 20a to the 1 st inclined side 27a and the 2 nd inclined side 27b in the axial direction of the tube. Accordingly, when the opening area of the lead-out opening 20a is the smallest, the entire flat plate portion 22a of the 2 nd sheet 22 exists in the tape winding region Tp, and the entire outer wall surface side becomes the wound portion of the tape 30. Therefore, regardless of the size of the opening area of the adjusted lead-out opening 20a, the entire flat plate portion 22a of the 2 nd sheet 22 is present in the tape winding region Tp, and the entire outer wall surface side becomes the wound portion of the tape 30. With such a configuration, the exemplary wire drawing structure 20 can suppress the wound portion of the tape 30 in the tape winding region Tp from being reduced as much as possible.
The wire drawing structure 20 is provided in 1 or 2 of the plurality of frame members (1 st frame member 11, 2 nd frame member 12, and 3 rd frame member 13) in the frame 10. In this example, the 1 st housing member 11 is provided with the flat plate portion 26 and the 2 nd side wall portions 27, and the 2 nd housing member 12 is provided with the variable sheet body 20A and the coupling portion 28. The wire lead-out structure 20 is formed by assembling the 1 st and 2 nd frame members 11 and 12.
As described above, in the wire drawing structure 20, regardless of the size of the opening area of the adjusted drawing port 20a, the 2 nd blade 22 is present in the tape winding region Tp, and the outer wall surface side of the 2 nd blade 22 of the tape winding region Tp becomes the wound portion of the tape 30, so that the wound portion of the tape 30 in the tape winding region Tp can be suppressed from being reduced. Thus, in the electrical junction box 1 of the present embodiment, the electric wires We can be fixed to the wire lead-out structure 20 with the tape 30 regardless of the size of the opening area of the lead-out opening 20a adjusted in accordance with the wire diameter and the number of the electric wires We.
