The present invention relates to a wiring member, a housing including the wiring member, and a storage battery unit including the housing.

Patent document 1 discloses a home battery unit that can supply power to home appliances, lighting equipment, air conditioning equipment, etc.

JP 2014-11920 A

Generally, a storage battery unit such as the home storage battery unit has a rectangular box-shaped housing that houses a storage battery, is fixed to a wall inside a room via this housing, and is electrically connected to external devices via wiring.

The battery unit is usually provided with an inlet on either the back or side of the housing to allow wiring to be pulled into the housing, allowing either concealed wiring, in which wiring arranged inside the wall is pulled into the housing through an inlet on the back of the housing and connected to the battery, or exposed wiring, in which wiring arranged along the wall is pulled into the housing through an inlet on the side of the housing and connected to the battery.

When determining the position of the inlet depending on where the storage battery unit is installed, it is possible to provide openings on the back and side of the housing, form an inlet in one opening to hold the wiring while drawing it into the housing, and block the other unused opening with a separate member. In this case, it is difficult to form an inlet in one opening while blocking the other opening with a single member, and it may be necessary to have a member to form the inlet in one opening and a member to block the other opening in addition to the member to form the inlet.

The objective of the present disclosure is to provide a wiring member that can be simultaneously attached to openings provided on two mutually intersecting faces of a housing, and that can block one opening while allowing the other opening to serve as a wiring inlet.

A wiring member according to an example of the present disclosure includes:
A wiring member that can be simultaneously attached to a first opening and a second opening of a housing having a first housing surface and a second housing surface that intersects with the first housing surface, the wiring member comprising:
a plate-like first member having a first plate surface extending in a first direction and a lead-in hole opening in the first plate surface into which a wiring can be inserted and held;
a plate-like second member having a second plate surface facing the first plate surface at an angle thereto and connected to one end of the first member in the first direction;
Each of the first member and the second member is
When viewed along a second direction intersecting the first direction and the plate thickness direction of the first member, the first member and the second member are configured symmetrically with respect to a virtual line passing through a middle of the first member and the second member,
a pair of fixing portions provided at both ends in the second direction, the fixing portions being capable of fixing the wiring member to the housing;
The pair of fixing portions fix one of the first member and the second member to the housing in a state where the other of the first member and the second member is attached to the second opening.

An example housing of the present disclosure includes:
The wiring member is provided.

An example storage battery unit of the present disclosure includes:
A storage battery,
The storage battery is accommodated in the housing.

The wiring member includes a plate-like first member having an inlet hole through which the wiring can be inserted, and a plate-like second member that faces the first member at an angle and is connected to one end of the first member. Each of the first member and the second member is configured symmetrically with respect to an imaginary line that passes through the middle of the first member and the second member. With this configuration, when attaching the wiring member to a housing having a first housing surface with a first opening and a second housing surface with a second opening that intersects with the first housing surface, it is possible to attach either the first member or the second member to the first opening, and the other of the first member or the second member to the second opening. As a result, it is possible to realize a wiring member that can be simultaneously attached to openings provided on two mutually intersecting surfaces of the housing, and one opening can be used as a wiring inlet while the other opening can be blocked.

The housing can be realized in such a way that any of the openings provided on the two mutually intersecting surfaces can be used as a wiring inlet by using the wiring member.

The battery unit described above can be realized by using the housing to provide a wiring inlet on any of the two intersecting faces of the housing.

In the following description, terms indicating specific directions or positions (e.g., terms including "up," "down," "right," and "left") will be used as necessary, but the use of these terms is intended to facilitate understanding of the present disclosure with reference to the drawings, and the meanings of these terms do not limit the technical scope of the present disclosure. In addition, the following description is essentially merely illustrative, and is not intended to limit the present disclosure, its applications, or its uses. Furthermore, the drawings are schematic, and the ratios of the dimensions do not necessarily correspond to reality.

As shown in FIG. 1, a storage battery unit 1 according to an embodiment of the present disclosure includes a storage battery 10 and a housing 20 in which the storage battery 10 is housed. In this embodiment, the storage battery 10 is composed of multiple cells, and the housing 20 includes a wiring member 50.

1, the housing 20 has a first housing 21 in which the storage battery 10 is housed, a second housing 22 in which a control unit 40 that controls the storage battery 10 is housed, and a base member 23 that fixes the first housing 21 to an installation position. In this embodiment, the housing 20 has two first housings 21.

Each first housing 21 is substantially rectangular, with the second housing 22 attached to one longitudinal end and the base member 23 attached to the other longitudinal end. Each first housing 21 houses one storage battery 10 and constitutes a storage battery device 2. The storage battery devices 2 are integrated in a state of mutual contact.

2, the second housing 22 has a first housing surface 24 and a second housing surface 25 intersecting the first housing surface 24. A substantially rectangular first opening 241 is provided in the first housing surface 24, and a substantially rectangular second opening 251 is provided in the second housing surface 25. One longitudinal end of the first opening 241 is connected to one longitudinal end of the second opening 251. The wiring member 50 is attached to the first opening 241 and the second opening 251 simultaneously.

As shown in FIG. 3, the wiring member 50 includes a plate-shaped first member 51 and a plate-shaped second member 52. The first member 51 and the second member 52 are connected via a plate-shaped curved portion 57.

The first member 51 has a substantially rectangular main body 511, a first plate surface 53 extending in the longitudinal direction of the main body 511 (an example of a first direction, for example, the X direction), and a retraction hole 54 opening in the first plate surface 53. One end of the main body 511 in the first direction X is connected to the main body 521 of the second member 52 described later via a curved portion 57. As shown in FIG. 5, the other end of the main body 511 in the first direction X is provided with a flange portion 512 extending in the plate thickness direction (for example, the Y direction) of the main body 511. The retraction hole 54 has a substantially circular shape, for example, and is configured to be able to insert and hold the wiring 100 (shown in FIG. 2) that is retracted into the interior of the second housing 22. In other words, the retraction hole 54 constitutes an inlet for the wiring 100. The first member 51 has a notch 55 that extends along the short side direction of the main body 511 (an example of the second direction, for example, the Z direction) and communicates with the draw-in hole 54 and the outside of the first member 51. In this embodiment, the notch 55 is configured so that the width W in the first direction X is smaller than the diameter D of the draw-in hole 54. The notch 55 is also disposed in the first direction X between a pair of fixing parts 61, 62, which will be described later.

The second member 52 has a substantially rectangular main body 521 and a second plate surface 56 that faces the first plate surface 53 of the first member 51 at an angle θ (e.g., 90 degrees). One end of the main body 521 in the first direction X is connected to the main body 511 of the first member 51 via a curved portion 57. As shown in FIG. 5, the other end of the main body 521 in the first direction X is provided with a flange portion 522 that extends in the plate thickness direction (e.g., the X direction) of the main body 521.

As shown in FIG. 5, when viewed along the second direction Z, each of the first member 51 and the second member 52 is configured symmetrically with respect to an imaginary straight line L that passes through the curved portion 57 and the middle of each of the main body portions 511, 521 of the first member 51 and the second member 52.

Each of the first member 51 and the second member 52 has a pair of fixing portions 61, 62 that fix the wiring member 50 to the second housing 22. The fixing portions 61, 62 are provided at both ends in the second direction Z that intersects with the first direction X and the plate thickness direction Y of the main body portion 511 of the first member 51. In this embodiment, as shown in FIG. 5, the fixing portions 61, 62 are arranged at both ends in the longitudinal direction of the main body portions 511, 521 when viewed along the second direction Z. The fixing portion 61 of the first member 51 and the fixing portion 62 of the second member 52 are arranged at the same end in the second direction Z (e.g., the upper end in FIG. 3). The fixing portion 62 of the first member 51 and the fixing portion 61 of the second member 52 are arranged on the opposite side of the fixing portion 61 of the first member 51 and the fixing portion 62 of the second member 52 in the second direction Z (e.g., the lower end in FIG. 3).

Each fixing portion 61, 62 is composed of a plate-shaped portion 611, 621 extending in the plate thickness direction of the main body portion 511, 521, and a through hole 612, 622 provided in each plate-shaped portion 611, 621. The edges of the first opening 241 and the second opening 251 of the second housing 22 are provided with screw holes (not shown) corresponding to each of the through holes 612, 622. The wiring member 50 is fixed to the second housing 22 by screws that can be inserted into each of the through holes 612, 622 and engaged with the screw holes.

As described above, each of the first member 51 and the second member 52 is configured symmetrically with respect to the imaginary line L when viewed along the second direction Z. Therefore, the wiring member 50 can be attached to the second housing 22 even when it is inverted with respect to the imaginary line L (in other words, rotated 180 degrees around the imaginary line L). That is, the wiring member 50 can be attached to the second housing 22 in either of the modes shown in FIG. 2 and FIG. 6. In FIG. 2, the first member 51 is attached to the first opening 241 of the second housing 22, and the second member 52 is attached to the second opening 251 of the second housing 22. As a result, the first opening 241 constitutes an inlet for the wiring 100, and the second opening 251 is blocked. In FIG. 6, the second member 52 is attached to the first opening 241 of the second housing 22, and the first member 51 is attached to the second opening 251 of the second housing 22. As a result, the second opening 251 forms an inlet for the wiring 100, and the first opening 241 is blocked.

The wiring member 50 provides the following effects:

The wiring member 50 includes a plate-like first member 51 having a lead-in hole 54 through which the wiring can be inserted, and a plate-like second member 52 that faces the first member 51 at an angle θ and is connected to one end of the first member 51. Each of the first member 51 and the second member 52 is configured symmetrically with respect to a virtual straight line L that passes through the middle of the first member 51 and the second member 52. With this configuration, when the wiring member 50 is attached to the second housing 22 having a first housing surface 24 in which a first opening 241 is provided and a second housing surface 25 in which a second opening 251 is provided and intersects with the first housing surface 24, one of the first member 51 and the second member 52 can be attached to the first opening 241, and the other of the first member 51 and the second member 52 can be attached to the second opening 251. As a result, it is possible to realize a wiring member 50 that can be simultaneously attached to the openings 241, 251 provided on the two mutually intersecting surfaces 24, 25 of the second housing 22 of the housing 20, allowing one opening to be used as a wiring inlet while blocking the other opening.

The first member 51 has a notch 55 that extends along the second direction and communicates with the lead-in hole 54 and the outside of the first member 51. With this configuration, the wiring 100 can be easily placed in the lead-in hole 54 without being inserted into the lead-in hole 54.

The lead-in hole 54 has a circular shape, and the width W of the notch 55 in the first direction is smaller than the diameter D of the lead-in hole 54. With this configuration, the wiring 100 arranged in the lead-in hole 54 can be held more reliably.

The housing 20 provides the following benefits:

It is possible to realize a housing 20 in which any of the openings provided on each of the two mutually intersecting surfaces can be used as an inlet for the wiring 100.

The storage battery unit 1 can provide the following benefits:

The housing 20 allows for the realization of a storage battery unit 1 that allows for a wiring 100 inlet to be provided on any of the two intersecting faces of the housing 20.

The wiring member 50, the housing 20 and the storage battery unit 1 can also be configured as follows.

The first member 51 and the second member 52 can be inverted with respect to the imaginary straight line L to adopt any shape and structure that can change the inlet of the wiring 100. For example, the first member 51 and the second member 52 are not limited to being in the shape of a substantially rectangular plate, and can adopt any shape that corresponds to the shape of the opening of the housing to which they are attached.

The pair of fixing parts 61, 62 are not limited to the above embodiment, and any structure capable of fixing the wiring member 50 to the openings 241, 251 of the housing 20 can be adopted.

The lead-in hole 54 is not limited to a circular shape, and can have any shape that allows the wiring 100 to be inserted and held.

The width W of the notch 55 in the first direction Z is not limited to being smaller than the diameter D of the draw-in hole 54, and can be set arbitrarily.

The notch 55 may be omitted.

This disclosure is not limited to the storage battery unit 1 described above, but can be applied to storage battery units 1 having a housing of any configuration that includes a wiring member 50.
