Description
Technical Field
The present invention relates to a bus bar and a resin body.
Background
The electric junction box of the related art is constituted by assembling a plurality of resin bodies to each other. Generally, an electrical junction box is constituted by a block main body and a frame. The electrical junction box is mounted on a vehicle, for example, and has a different circuit configuration depending on the type, class, and the like of the mounted vehicle. Therefore, a base area commonly used by any vehicle and one or more optional areas used for only a part of the vehicles are formed inside the block main body (for example, refer to patent document 1).
In the above-described related-art electrical junction box, a base block having a base circuit is accommodated in a base region, and a void is provided in advance in an optional region. An optional block having an optional circuit according to the type, class, etc. of the vehicle is mounted in the cavity.

Technical problem to be solved by the invention
Generally, in an electrical junction box, bus bars each of a base block and an optional block are overlapped and bonded to each other by screws or the like. Thereby, the base block and the optional block are electrically connected to each other. However, since the electrical junction box is mounted on the vehicle, there are cases where the plurality of blocks move in different directions or the vibration frequency is different even if the blocks move in substantially the same direction due to complex vibrations in the vehicle. Thus, the frame and the base block, the frame and the optional block may be moved differently (so-called out-of-phase movement). Thus, a large stress (specifically, tension, attraction, etc. between the bus bars) is applied to the joint between the bus bars. As a result, stress is also generated around the bonding site of the bus bar, and the bus bar may be broken.
On the other hand, in order to prevent the bus bars from being damaged due to the above-described problems, there is also a method of absorbing complex vibrations in a vehicle by connecting the bus bars to each other by a wire harness. However, the above-described method requires wires electrically connecting the respective bus bars, and connectors provided at both ends of the respective bus bars and the wires. That is, the above-described method is not preferable from the viewpoint of cost because the number of parts increases. Further, since a wire harness is used, a space for wiring the electric wire is required inside the electric junction box, and therefore the above method is not preferable from the viewpoint of the storage property of the electric junction box.
The invention provides a bus bar and a resin body, which are configured to restrain stress caused by external force generated at a joint part of the bus bars to be joined and in the vicinity of the joint part.
Technical means for solving the technical problems
In order to achieve the above object, the bus bar and the resin body according to the present invention are characterized by the following [1] to [3 ].
[1]
A bus bar configured to be accommodated in a resin body, and configured to be coupled to a mating-side bus bar, the bus bar comprising:
a main body portion configured to be accommodated in the resin body;
a coupling portion configured to be coupled to the mating-side bus bar;
a connecting portion connecting the main body portion and the joining portion
The connecting portion has:
a first portion connected to the joint;
a second portion connected to the main body portion; and
an extension connecting the first portion and the second portion;
the connecting portion has a shape in which the end portion of the first portion on the joint portion side and the end portion of the extending portion on the joint portion side approach each other around a predetermined first center, and a surface of the first portion facing the first center is a curved surface,
the connecting portion has a shape in which an end portion of the second portion on the main body portion side and an end portion of the extending portion on the main body portion side approach each other around a predetermined second center, and a surface of the second portion facing the second center is a curved surface.
[2]
In the bus bar described in the above [1],
the main body portion and the coupling portion are located at different positions in a predetermined direction.
[3]
A resin body is provided with: a first block having a first bus bar; and a second block having a second bus bar configured to be coupled to the first bus bar,
the second bus bar includes:
a body portion configured to be accommodated in the second block;
a coupling portion configured to be coupled to the first bus bar; and
a connecting portion connecting the main body portion and the joining portion,
the connecting portion has:
a first portion connected to the joint;
a second portion connected to the main body portion; and
an extension portion connecting the first portion and the second portion,
the connecting portion has a shape in which the end portion of the first portion on the joint portion side and the end portion of the extending portion on the joint portion side approach each other around a predetermined first center, and a surface of the first portion facing the first center is a curved surface,
the connecting portion has a shape in which an end portion of the second portion on the main body portion side and an end portion of the extending portion on the main body portion side approach each other around a predetermined second center, and a surface of the second portion facing the second center is a curved surface.
The bus bar having the structure of [1] is described below. In general, after bonding the bus bar and the mating-side bus bar, when the bus bars move to so-called different phases from each other due to an external force, a large stress is generated at the bonding portion of the bus bars. In addition, in the bus bar, stress is generated not only at the bonding site but also in the vicinity of the bonding site. However, the bus bar of this structure has the curved surface at each of the first portion and the second portion, and therefore, stress concentration at or near the joining portion can be relaxed as compared with the case where the bus bar does not have the curved surface. That is, the bus bar of this structure has a curved surface at the connecting portion, so that stress is not locally concentrated (that is, stress can be suppressed). In other words, the first portion and the second portion of the bus bar of the present structure have the curved surface and the main body portion connecting the end portion on the coupling portion side of the coupling portion and the end portion on the coupling portion side of the extension portion at the convex side of the curved surface, and thus, the above-described stress concentration can be made more difficult to occur regardless of the shape of the main body portion of the first portion and the second portion than in the case where the bus bar does not have the curved surface. As a result, the bus bar of this structure can alleviate stress due to external force generated at and near the bonding sites of the bonded bus bars to each other.
The bus bar having the structure of [2] is described below. In general, in the case where the main body portion and the joint portion are located at different positions in a predetermined direction (for example, up-down direction), the above-described stress concentration easily occurs when the bus bars are moved to different phases from each other as described above. On the other hand, in the bus bar of this structure, since the first portion and the second portion have curved surfaces, such stress concentration can be suppressed. As a result, the bus bar of the present structure can more appropriately alleviate stress due to external force generated at and near the bonding sites of the bonded bus bars to each other.
According to the resin body of the above [3], since the first portion and the second portion of the second bus bar each have a curved surface, the stress concentration can be relaxed as compared with the case where the second bus bar does not have a curved surface. That is, since the connecting portion of the second bus bar has a curved surface, stress is not locally concentrated (that is, stress can be suppressed). As a result, the resin of the present structure can alleviate stress due to external force generated at and near the bonding sites of the bonded bus bars.
Further, as another effect, since the first block and the second block are bonded to each other by the bus bars (i.e., the first bus bar and the second bus bar), the resin body of this structure is superior in cost and in storage property of the electrical junction box as compared with the connection method using the wire harness.
Effects of the invention
Thus, according to the present invention, it is possible to provide a bus bar and a resin body that suppress stress due to external force generated at and near the joint portions of the bus bars to be joined.
The present invention is briefly described above. Further, the details of the present invention will be further apparent by reading the following modes for carrying out the invention with reference to the accompanying drawings.

Detailed Description
Embodiment
The resin structure 1 according to the embodiment of the present invention shown in fig. 1 will be described below with reference to the drawings. The resin structure 1 is typically a relay box (electrical junction box) mounted on a vehicle and accommodating electronic components such as a relay.
As shown in fig. 1, the resin structure 1 includes: a block main body 10 configured to house electronic components (other components, not shown) of the relay; and a frame 20 mounted to enclose the outer circumference of the block body 10. The block main body 10 and the frame 20 are each a resin structure 1. The block main body 10 corresponds to a "first resin body" of the present invention, and the frame 20 corresponds to a "second resin body" of the present invention.
Hereinafter, for convenience of explanation, as shown in (b) of fig. 1 to 6, "up-down direction", "circumferential direction", "inside-outside direction", "up", "down", "inside" and "outside" are defined. The "up-down direction", "circumferential direction" and "inside-outside direction" are orthogonal to each other. In the resin structure 1, the "up-down direction" corresponds to the mounting direction of the block main body 10 and the frame 20. The "circumferential direction" corresponds to the circumferential direction of the peripheral wall 11 of the block main body 10 and the peripheral wall 21 of the frame 20, which will be described later, and the "inward and outward direction" corresponds to the thickness direction of the peripheral wall 11 and the peripheral wall 21.
As shown in fig. 1, the resin structure 1 is provided with engagement portions (i.e., the engagement portions 12 and the engagement portions 22) at a plurality of portions (in this example, four portions) in the circumferential direction. At the engagement portion, the block main body 10 and the frame 20 are engaged in the mounted state thereof to prevent the separation thereof in the up-down direction. Next, the respective members constituting the resin structure 1 will be described in order.
First, the block body 10 will be described. The block main body 10 is molded from a resin material such as polyphenylene ether (PPE), and has a substantially rectangular cylindrical peripheral wall 11 partially recessed and extending in the up-down direction as shown in fig. 1. The peripheral wall 11 of the block body 10 is provided with an engagement portion 12 that engages with the engagement portion 22 of the frame 20.
As shown in fig. 2, the block body 10 is composed of a base block 30 and an optional block 40. Specifically, the optional block 40 is attached to the housing portion 32 of the base block 30 (described later) from above, thereby forming the block body 10 (see fig. 3).
As shown in fig. 3 to 4, the base block 30 includes a peripheral wall 31, a housing portion 32, an inner wall 33, and a base-side bus bar 300. The peripheral wall 31 forms a peripheral wall 11, and has a substantially rectangular tubular shape that is partially recessed and extends in the up-down direction, like the peripheral wall 11. That is, the outer shape of the base block 30 constitutes the outer shape of the block main body 10.
The housing portion 32 is surrounded by an inner wall 33 (for example, including the inner side of the peripheral wall 31) and is provided inside the base block 30. An optional block 40 is mounted in the receptacle 32.
The inner wall 33 is provided with a first engagement portion 35 (see fig. 2) to be engaged with a second engagement portion 42 of the optional block 40. The optional block 40 is attached to the base block 30 by engagement of the first engagement portion 35 and the second engagement portion 42.
The base-side bus bar 300 has, for example, an engaging portion (not shown), and the engaging portion of the base-side bus bar 300 engages with a bus bar engaging portion (not shown) of the base block 30. The base-side bus bar 300 may be insert molded in the base block 30. As shown in fig. 4 and 6 (a) and 6 (b), the base-side bus bar 300 includes a joint 301 joined to the optional-side bus bar 400, a main body 302 connected to an electronic component (for example, a base circuit) and the like, and a joint 303 connecting the joint 301 and the main body 302.
The joint 301 is provided with an insertion hole 301a into which the bolt 2 is inserted. The insertion hole 301a is coupled with the insertion hole 401a of the optional side bus bar 400 by the bolt 2 and the nut 3. As shown in fig. 4, the coupling portion 301 and the main body portion 302 are separated in the circumferential direction and the up-down direction, and are coupled by a coupling portion 303.
As shown in fig. 3 and 5, the optional block 40 includes a peripheral wall 41, a second engagement portion 42, and an optional side bus bar 400. The peripheral wall 41 has a substantially rectangular tubular shape extending in the up-down direction, and a second engagement portion 42 is provided on the outer side of the peripheral wall 41. The peripheral wall 41 has a shape along the housing portion 32. Thereby, the option block 40 may be accommodated in the base block 30 (i.e., the accommodation portion 32).
The selectable-side bus bar 400 has, for example, an engaging portion (not shown) that engages the engaging portion of the selectable-side bus bar 400 with the bus bar engaging portion (not shown) of the selectable block 40. In addition, the option side bus bar 400 may also be insert molded in the option block 40. As shown in fig. 5 to 6 (b), the optional side bus bar is composed of a coupling portion 401 coupled to the base side bus bar 300, a main body portion 402 connected to an electronic component (for example, an optional circuit) or the like, and a coupling portion 403 coupling the coupling portion 401 and the main body portion 402.
The joint 401 is provided with an insertion hole 401a through which the bolt 2 is inserted. The insertion hole 401a is coupled with the insertion hole 301a of the base-side bus bar 300 by the bolt 2 and the nut 3. As shown in fig. 5, the coupling portion 403 couples the coupling portion 401 and the main body portion 402, and the coupling portion 401 and the main body portion 402 are located at different positions in the up-down direction and are separated in the circumferential direction.
The connecting portion 403 has a first portion 411 located on the coupling portion 401 side, a second portion 412 located on the main body portion 402 side, and an extension portion 413 located between the first portion 411 and the second portion 412. The extension 413 extends from the first location 411 to the second location 412. Specifically, the extension portion 413 extends from the end 413a on the coupling portion 401 side to the end 413b on the main body portion 402 side.
The coupling portion 403 has a shape (e.g., a curved shape) in which an end 403a that is an end on the coupling portion 401 side of the first portion 411 and an end 413a on the coupling portion 401 side of the extension portion 413 approach each other around the first center O1. For example, the connecting portion 403 has a shape in which a distance between an end 403a of the first portion 411 on the side of the joint portion 401 and an end 413a of the extension portion 413 on the side of the joint portion 401 is smaller in a portion located radially inward of a virtual circle centered on the first center O1 than in a portion located radially outward thereof. Further, the first portion 411 has a curved surface 411a on a surface facing the first center O1 (i.e., a surface near the first center O1). In other words, the first portion 411 has a curved surface 411a and a main body portion that connects the end 403a and the end 413a on the convex side of the curved surface 411a. In other words, the first portion 411 has a curved surface 411a and a main body portion connecting the end 403a and the end 413a radially outward of the curved surface 411a in a virtual circle centered on the first center O1.
The coupling portion 403 has a shape (e.g., a curved shape) in which an end 403b that is an end of the second portion 412 on the main body portion 402 side and an end 413b of the extension portion 413 on the main body portion 402 side are close to each other around the second center O2. For example, the coupling portion 403 has a shape in which a distance between an end 403b of the second portion 412 on the main body portion 402 side and an end 413b of the extension portion 413 on the main body portion 402 side is smaller in a portion located radially inward of a virtual circle centered on the second center O2 than in a portion located radially outward thereof. The second portion 412 has a curved surface 412a on a surface facing the second center O2 (i.e., a surface near the second center O2). In other words, the second portion 412 has a curved surface 412a and a main body portion that connects the end 403b and the end 413b on the convex side of the curved surface 412a. In other words, the second portion 412 has a curved surface 412a and a main body portion connecting the end 403b and the end 413b radially outward of the curved surface 412a in a virtual circle centered on the second center O2.
By forming the first portion 411 and the second portion 412 as described above, the coupling portion 403 has a substantially S-shape when viewed in a direction intersecting the up-down direction (the inside-out direction or the circumferential direction) (see (b) of fig. 6). The substantially S-shaped form also includes an inverted S-shaped form.
By coupling the base side bus bar 300 and the option side bus bar 400 with the bolts 2 and the nuts 3, electricity is supplied between the base block and the option block. I.e. the base block and the optional block are integrated circuits.
Further, the base side bus bar 300 and the optional side bus bar 400 are coupled by the bolts 2 and the nuts 3 so that the coupling parts 301 and 401 overlap each other. That is, the plate thickness of the bus bar is doubled by overlapping the two bus bars, and thus the heat resistance is increased.
Next, the frame 20 will be described. The frame 20 is formed of a resin material such as polypropylene (PP), and has a substantially rectangular cylindrical peripheral wall 21 partially recessed and extending in the up-down direction as shown in fig. 1. An engagement portion 22 that engages with the engagement portion 12 of the block body 10 is provided on the inner side of the peripheral wall 21. For example, an engaging portion 23 that engages with a lower cover (not shown) is provided on the outside and below the peripheral wall 21.
The engagement portion 23 may be provided on the outer side and upper side of the peripheral wall 21, and may engage with an upper cover (not shown). The engaging portion 23 may be provided on the outer side and upper portion of the peripheral wall 21, and on the outer side and lower portion of the peripheral wall 21, and may engage with the upper cover and the lower cover.
< action, effect >)
The bus bar (optional side bus bar 400) of the present embodiment will be described below. In general, after bonding the optional side bus bar 400 and the base side bus bar 300, when the bus bars move to so-called different phases from each other due to an external force, a large stress is generated at bonding portions (i.e., the bonding portions 301 and 401) of the bus bars. In addition, in the optional side bus bar 400, stress is generated not only at the bonding site but also in the vicinity of the bonding site. However, since the first portion 411 and the second portion 412 of the selectable-side bus bar 400 according to the present embodiment have curved surfaces (that is, the curved surfaces 411a and 412 a), stress concentration at or near the joining portion can be relaxed as compared with the case where there is no curved surface. That is, since the coupling portion 403 of the optional side bus bar 400 has a curved surface, stress is not locally concentrated (i.e., stress can be suppressed). In other words, the first portion 411 and the second portion 412 of the selectable-side bus bar 400 have curved surfaces and a main body portion that connects the end 403a on the joint 401 side of the connecting portion 403 and the end 413a on the joint 401 side of the extending portion 413 at the convex side of the curved surfaces, so that the above-described stress concentration can be made more difficult to occur than in the case where no curved surface is provided, regardless of the shape of the main body portions of the first portion 411 and the second portion 412. As a result, the optional side bus bar 400 can alleviate stress due to external force generated at and near the bonding sites of the bonded bus bars to each other.
In addition, the following description is made with respect to the optional side bus bar 400 of the present embodiment. In general, in the case where the main body portion 402 and the coupling portion 401 are located at different positions in a predetermined direction (for example, up-down direction), the above-described stress concentration easily occurs when the bus bars are moved to different phases from each other in the manner described above. On the other hand, in the optional side bus bar 400 of the present embodiment, such stress concentration can be suppressed by having the first portion 411 and the second portion 412 with curved surfaces. As a result, the optional side bus bar 400 (i.e., the resin structure 1) can more appropriately alleviate stress due to external forces generated at and near the bonding sites of the bus bars to be bonded to each other.
In the present embodiment, the main body 402 and the coupling portion 401 located at different positions in the up-down direction are coupled by the coupling portion 403 (see fig. 6 (b)), and the coupling portion 403 has a substantially S-shape when viewed in a direction intersecting the up-down direction. Thus, even if the main body 402 and the coupling portion 401 are displaced in the up-down direction (i.e., even if they are moved in different directions in the up-down direction), the stress is relaxed by the coupling portion 403. That is, the connecting portion 403 has a substantially S-shape, so that stress in the up-down direction can be suppressed.
According to the block body 10 of the present embodiment, the first portion 411 and the second portion 412 of the optional side bus bar 400 have curved surfaces (i.e., the curved surface 411a and the curved surface 412 a), respectively, so that the above-described stress concentration can be relaxed compared with the case where there is no curved surface. That is, in the optional side bus bar 400, since the coupling portion 403 has a curved surface, stress is not locally concentrated (i.e., stress can be suppressed). As a result, the block body 10 of the present embodiment can alleviate stress due to external force generated at and near the joint of the joined bus bars.
Further, in the block main body 10 of the present embodiment, since the base block 30 and the optional block 40 are coupled to each other by bus bars (i.e., the base side bus bar 300 and the optional side bus bar 400), it is excellent in cost and storage performance of the electrical junction box as compared with the connection method using a wire harness.
< other modes >
The present invention is not limited to the above-described embodiments, and can be appropriately modified or improved. The material, shape, size, number, arrangement position, and the like of the respective constituent elements in the above embodiment are not limited as long as the present invention can be realized.
In the present embodiment, the surface of the first portion 411 away from the first center O1 also has a curved surface (so-called corner-free shape). However, the surface of the first portion 411 away from the first center O1 may not have a curved surface. That is, the shape of the main body portion of the first portion 411 on the convex side of the curved surface 411a is not particularly limited, and may be the shape of the present embodiment or other shapes. The shape of the present embodiment is preferable.
In the present embodiment, the surface of the second portion 412 distant from the second center O2 also has a curved surface (so-called corner-free shape). However, the surface of the second portion 412 away from the second center O2 may not have a curved surface. That is, the shape of the main body portion of the second portion 412 on the convex side of the curved surface 412a is not particularly limited, and may be the shape of the present embodiment or other shapes. The shape of the present embodiment is preferable.
In the present embodiment, the optional side bus bar 400 is configured to have the curved surface 411a and the curved surface 412a, but the base side bus bar 300 may be formed in the same manner.
