Description

【0001】
【発明の属する技術分野】
本発明は、例えば、自動車の車両組付け用のリレーボックス等の電気接続箱の結合構造に関する。
【0002】
【従来の技術】
この種の電気接続箱の結合構造として、図5に示すものがある。このような結合構造は、車両の仕向地違いによるリレー、ヒューズ等の仕様アップに対応する際に、2つの同形状の電気接続箱を結合することで、部品の種類を増やさずに済み、製造コストが削減できるという理由で、従来から使用されている。
【0003】
このような結合構造に用いられる電気接続箱1は、図5〜図7に示すように、合成樹脂製で直方体状の接続箱本体2を有している。この接続箱本体2はその正面2aにロック部3を突設してある。また、接続箱本体2の背面2bには、ガタ防止を兼ねた保持部4と接続箱本体2の正面2aのロック部3に係止される被ロック部5とをそれぞれ設けている。そして、図5に示すように、2つの電気接続箱1、1がロック部3と被ロック部5を介して結合されるようになっている。
【0004】
なお、この電気接続箱1の結合構造に関する類似技術は、特開平5−336637号公報に開示されている。
【0005】
【発明が解決しようとする課題】
しかしながら、前記従来の電気接続箱1の結合構造では、2つの接続箱本体2、2を結合させて汎用性を持たせるには、接続箱本体2の正面2aと背面2bにロック部3と被ロック部5をそれぞれ設ける必要があるため、製造に必要な金型の形状が複雑になり、金型の製作コストを増大させていた。
【0006】
さらに、2つの接続箱本体2、2を結合した場合には、その前後に不要なロック部3と、被ロック部5が発生するために、全体として大型化してしまう。これにより、余分な原料が必要となり、製造コストの増大を招いてしまう。さらに、大型化することで、電気接続箱1を車体に取り付ける際に余分な空間を必要としていた。
【0007】
また、前記した課題の対策として、ロック部3と被ロック部5を1つの電気接続箱には設けずに、別の電気接続箱に分けて設ける方法が考えられるが、この方法では複数の金型が必要となるため、汎用性が低く、金型の製作コストが増大するために、部品の種類を減らしてコストを削減するという、本来の目的を失ってしまう。
【0008】
そこで、本発明は、前記した課題を解決すべくなされたものであり、1つの金型で製造が可能で、小型化と、低コスト化が可能な、汎用性の高い電気接続箱の結合構造を提供することを目的とする。
【0009】
【課題を解決するための手段】
請求項1の発明は、車両組付け用の2つの同形状の接続箱本体を係合部と係止部を介して結合自在にした電気接続箱の結合構造において、前記各接続箱本体の片側に相手側の接続箱本体の係合部に相互に係合される係合部を設けると共に、該相手側の接続箱本体の係止部に相互に係止される係止部を設け、かつ前記各接続箱本体の片側に少なくとも一対の係止部を設け、この一対の係止部に上下方向相互の係止状態を保持する係止突起をそれぞれ設けたことを特徴とする。
【0010】
この電気接続箱の結合構造は、電気接続箱本体の片側に結合構造の構成要素が全て備えられているので、結合部が相手側と同一形状になるため、1つの金型で製造が可能で、金型形状の簡素化による金型製作のコスト削減と、結合に使用されない結合構造を省くことによる小型化と、これに伴う原材料の削減による製造コストが削減される。特に、上下方向相互の係止状態を保持する係止突起を設けることで、電気接続箱の結合作業が2方向から行えるようになるため、結合作業時の作業性が改善される。
【0013】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。
【0014】
図1は本発明の一実施形態の電気接続箱の結合状態を示す平面図、図2は同電気接続箱の平面図、図3は同電気接続箱の正面図、図4(a)は同電気接続箱の結合前の状態を示す正面図、図4(b)は同電気接続箱の結合状態を示す正面図である。
【0015】
図1〜図3に示すように、電気接続箱10の接続箱本体11は合成樹脂により直方体状に形成してある。この接続箱本体11の一側面11aには車両組付け用の取付片部20を一体突出形成してあると共に、この接続箱本体11の上面11cには図示しないリレーやヒューズ等を装着する部品装着部21、22を形成してある。なお、図1、図4(a)において、説明の都合上、結合相手の接続箱本体を11′で、かつ2点鎖線で示す。
【0016】
また、接続箱本体11の正面11dには、相手側の接続箱本体11′の一対の係合部13、12に相互に係合される一対の係合部12、13を設けると共に、相手側の接続箱本体11′の左右各一対の係止部15、14に相互に係止される左右各一対の係止部14、15を設けられている。
【0017】
図2に示すように、接続箱本体11の正面11dに設けられた各係合部12は、平面T字形で、かつ接続箱本体11の上下方向(結合作業方向)に延びるレール形状をしている。また、接続箱本体11の正面11dに設けられた各係合部13は、T字形の係合部12を囲むような平面略C字形で、かつ接続箱本体11の上下方向(結合作業方向)に延びるレール形状をしている。なお、係合部13が係合部12を囲むような形状のため、係合した一対の係合部12、13を結合作業方向以外には分解することはできないようになっている。さらに、一対の係合部12、13は共に両端部が開放端となっているため、上方および下方の2方向から同一形状の接続箱本体11、11′の結合作業を行うことができるようになっている。
【0018】
また、図3に示すように、接続箱本体11の正面11dに設けられた各係止部14は、係止突起14aと導入部14bを備えている。さらに各係止部15は、係止突起15aと、アーム部15bと、屈曲部分15cと、支持部分15dを備え、係止突起15aがアーム部15bの撓み変形により、図3中矢印Aの方向に移動するようにアーム部15bと屈曲部分15cが支持部分15dに支えられるように配設されている。
【0019】
なお、接続箱本体11の背面11eにはコネクタ40を装着する係止部30を一体突出形成してあり、この係止部30にコネクタ40が後付けされるようになっている。
【0020】
次に、この電気接続箱10の結合動作を図4(a)、図4(b)を用いて説明する。2つの接続箱本体11、11′を一対の係合部12、13と各一対の係止部14、15を介して結合するために、図4(a)中の矢印Bの方向に接続箱本体11′をスライドさせると、接続箱本体11の係止突起15aが、相手側の接続箱本体11′の導入部分14bと干渉するが、接続箱本体11のアーム部15bと屈曲部分15cが撓み変形して、係止突起15aが支持部分15d側に移動することで、係止突起15aが係止部14の上に乗り、結合作業が妨げられることはない。
【0021】
また、接続箱本体11の係止突起14aは、相手側の接続箱本体11′のアーム部15bと干渉するが、これも相手側の接続箱本体11′のアーム部15bと屈曲部分15cが撓み変形し、相手側の接続箱本体11′の係止突起15aが支持部分15d側に移動することで、結合作業を妨げることはない。なお、結合作業がさらに進むと、相手側の接続箱本体11′のアーム部15bと干渉していた接続箱本体11の係止突起14aは、相手側の接続箱本体11′の係止突起15aと干渉するようになるが、係止突起14a、15aの干渉面は互いに結合方向に対して斜めに設けられているため、結合作業が進むにしたがって、相手側の接続箱本体11′のアーム部15bと屈曲部分15cが、さらに撓み変形をして、係止突起15aが係止突起14aを乗り越える。
【0022】
この状態を示したのが図4(b)である。図4(b)の状態になると、相手側(斜線側)の接続箱本体11′を図の下方にさらに押し込もうとしても、接続箱本体11の係止突起15aが、相手側の接続箱本体11′の係止突起14aのストッパとなり、2つの接続箱本体11、11′が脱落するのを防止できる。また、相手側の接続箱本体11′を図の上方に引き抜こうとしても、接続箱本体11の係止突起14aが相手側の接続箱本体11′の係止突起15aをロックして、2つの接続箱本体11、11′が脱落するのを防止できるため、2つの電気接続箱10、10の結合状態が保持され、結合が完了する。
【0023】
なお、図4(a)、図4(b)では、相手側の接続箱本体11′を図の上方から結合する場合を示したが、相手側の接続箱本体11′を図の下方から結合しても、各一対の係止部14、15が上記説明と同様な動作を行うため、2つの電気接続箱10、10を結合することができる。
【0024】
また、同形状の2つの電気接続箱10、10が結合するように一対の係合部12、13と左右各一対の係止部14、15を配設すると、同形状の2つの電気接続箱10、10を結合した場合に各接続箱本体11、11′の上面11cが同じ高さになり、さらに一対の係合部12、13と左右各一対の係止部14、15の配設する位置によって、各接続箱本体11、11′の側面同士を同じ位置にすることができる。
【0025】
つまり、本実施形態の結合構造は、接続箱本体の片側に結合構造の構成要素が全て備えられているので、結合部が相手側と同一形状になるため、1つの金型で製造が可能で、金型形状の簡素化による金型製作のコスト削減が可能である。さらに同一形状の電気接続箱を結合することができるので、汎用性の高い電気接続箱の製造が可能である。また、結合に使用されない結合構造を配設せずに済むことによる小型化と、これに伴う原材料の削減による製造コストの削減が可能である。
【0026】
さらに、本実施形態の結合構造では、上下方向相互の係止状態を保持する係止突起を設けることで、電気接続箱の結合作業が2方向から行えるようになるため、結合作業時の作業性が改善される。
【0027】
また、接続箱本体11の背面11eに係止部30を配設し、コネクタ40を取り付けることが可能になることで、複数のコネクタ40が電気接続箱10に集められるため、電気系統の点検、修理などの作業性が改善される。
【0028】
なお、以上説明した実施形態は、本発明の理解を容易にするために記載されたものであって、本発明を限定するものではない。したがって、本実施形態に示された各要素は、本発明の技術範囲に属する全ての設計上の選択事項をも含む趣旨である。
【0029】
たとえば、本実施形態では、一対の係合部12、13が左右各一対の係止部14、15を挟むように配設されているが、係止部14、15が係合部12、13を挟むように配設しても構わない。また、一対の係合部12、13と左右各一対の係止部14、15を配設する位置によっては、電気接続箱10を取り付ける車体の空間に合うように、各接続箱本体11、11′の側面をずらして結合することも可能である。
【0030】
さらに、本実施形態では一対の係合部12、13と左右各一対の係止部14、15とが別々の部材で構成されているが、係合部12、13に係止機能を持たせたり、または係止部14、15に係合機能を持たせて各部を配設しても構わない。
【0031】
つまり、同一形状の結合部を対向させた場合に、結合可能な形状に係止部と係合部とが設計されていれば、電気接続箱の結合構造は本実施形態に何ら限定されるものではない。
【0032】
【発明の効果】
以上説明したように、請求項1の発明によれば、電気接続箱本体の片側に結合構造の構成要素が全て備えられているので、結合部が相手側と同一形状になるため、1つの金型で製造が可能であるという効果と、金型形状の簡素化による金型製作のコスト削減が可能であるという効果がある。さらに、同一形状の電気接続箱が結合できるので、汎用性の高い電気接続箱の製造が可能であるという効果がある。また、結合に使用されない結合構造を配設しないことによる小型化と、これに伴う原材料の削減による製造コストの削減が可能になるという効果がある。
【0033】
さらに、電気接続箱の空いた面に係止部を配設し、コネクタを取り付けることが可能になるため、複数のコネクタが電気接続箱に集められるので、電気系統の点検、修理などの作業性が改善され、加えて、同形状の2つの電気接続箱を結合するには、結合方向に対して、係合部と係止部のそれぞれが接続箱本体の上面から同じ距離になければならないため、同形状の2つの電気接続箱を結合すると、2つの上面が同じ高さになるという効果がある。
【0034】
特に、上下方向相互の係止状態を保持する係止突起を設けることで、電気接続箱の結合作業が2方向から行えるようになるため、結合作業時の作業性が改善されるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a connection structure of an electrical connection box such as a relay box for assembling a vehicle of an automobile.
[0002]
[Prior art]
FIG. 5 shows a coupling structure of this type of electrical junction box. Such a coupling structure can be manufactured without increasing the number of parts by combining two electrical connection boxes of the same shape when dealing with increased specifications of relays, fuses, etc. due to different destinations of the vehicle. It has been used for the reason that the cost can be reduced.
[0003]
As shown in FIGS. 5 to 7, the electrical junction box 1 used for such a coupling structure has a rectangular parallelepiped junction box body 2 made of synthetic resin. The connection box main body 2 has a lock portion 3 protruding from the front surface 2a. Further, on the back surface 2 b of the connection box body 2, a holding part 4 that also serves to prevent backlash and a locked part 5 that is locked to the lock part 3 on the front surface 2 a of the connection box body 2 are provided. Then, as shown in FIG. 5, the two electrical junction boxes 1 and 1 are coupled via the lock portion 3 and the locked portion 5.
[0004]
A similar technique relating to the coupling structure of the electrical junction box 1 is disclosed in JP-A-5-336637.
[0005]
[Problems to be solved by the invention]
However, in the connection structure of the conventional electric junction box 1, in order to combine the two junction box bodies 2 and 2 and to have versatility, the front panel 2a and the rear surface 2b of the junction box body 2 have a lock portion 3 and a cover. Since it is necessary to provide each of the lock portions 5, the shape of the mold necessary for manufacturing becomes complicated, and the manufacturing cost of the mold is increased.
[0006]
Further, when the two junction box bodies 2 and 2 are coupled, unnecessary lock portions 3 and locked portions 5 are generated before and after the connection box main bodies 2 and 2, which increases the size as a whole. As a result, extra raw materials are required, leading to an increase in manufacturing costs. Furthermore, since the size is increased, an extra space is required when the electrical junction box 1 is attached to the vehicle body.
[0007]
Further, as a countermeasure for the above-described problem, there is a method in which the lock portion 3 and the locked portion 5 are not provided in one electrical junction box but are provided separately in another electrical junction box. Since a mold is required, the versatility is low, and the manufacturing cost of the mold increases, so that the original purpose of reducing the cost by reducing the types of parts is lost.
[0008]
Therefore, the present invention has been made to solve the above-described problems, and can be manufactured with a single mold, and can be miniaturized and reduced in cost. The purpose is to provide.
[0009]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided an electrical junction box coupling structure in which two junction box bodies having the same shape for vehicle assembly are freely coupled via an engaging portion and a locking portion. An engaging portion that is engaged with the engaging portion of the mating connection box body , and a locking portion that is locked with the locking portion of the mating connection box body , and It is characterized in that at least a pair of locking portions are provided on one side of each of the connection box main bodies, and locking protrusions for holding the locking states in the vertical direction are provided on the pair of locking portions, respectively .
[0010]
This electrical junction box coupling structure has all the components of the coupling structure on one side of the electrical junction box body, so the coupling part has the same shape as the mating side, so it can be manufactured with one mold. The manufacturing cost can be reduced by reducing the cost of manufacturing the mold by simplifying the mold shape, reducing the size by omitting the connecting structure that is not used for the connecting, and reducing the raw materials. In particular, by providing the locking projections that hold the locked state in the vertical direction, the electrical connection box can be joined from two directions, so that the workability during the joining work is improved.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0014]
FIG. 1 is a plan view showing a connection state of an electrical junction box according to an embodiment of the present invention, FIG. 2 is a plan view of the electrical junction box, FIG. 3 is a front view of the electrical junction box, and FIG. FIG. 4B is a front view showing a connected state of the electrical junction box, and FIG. 4B is a front view showing the joined state of the electrical junction box.
[0015]
As shown in FIGS. 1-3, the junction box main body 11 of the electrical junction box 10 is formed in the shape of a rectangular parallelepiped with synthetic resin. A mounting piece 20 for assembling the vehicle is integrally formed on one side surface 11a of the connection box main body 11, and a component or the like for mounting a relay or a fuse (not shown) on the upper surface 11c of the connection box main body 11 is mounted. Portions 21 and 22 are formed. In FIG. 1 and FIG. 4 (a), for convenience of explanation, the junction box main body of the coupling partner is indicated by 11 'and a two-dot chain line.
[0016]
In addition, the front surface 11d of the junction box body 11 is provided with a pair of engagement portions 12 and 13 that are engaged with the pair of engagement portions 13 and 12 of the counterpart connection box body 11 ', and the counterpart side A pair of left and right engaging portions 14 and 15 that are mutually engaged with the pair of left and right engaging portions 15 and 14 of the connection box main body 11 'are provided.
[0017]
As shown in FIG. 2, each engaging portion 12 provided on the front surface 11 d of the connection box body 11 has a planar T shape and has a rail shape extending in the vertical direction of the connection box body 11 (coupling operation direction). Yes. Further, each engaging portion 13 provided on the front surface 11d of the junction box body 11 is substantially planar C-shaped so as to surround the T-shaped engagement portion 12, and the vertical direction of the junction box body 11 (coupling operation direction). It has a rail shape extending to Since the engagement portion 13 surrounds the engagement portion 12, the pair of engaged portions 12, 13 cannot be disassembled except in the coupling work direction. Furthermore, since both ends of the pair of engaging portions 12 and 13 are open ends, it is possible to perform the connecting operation of the junction box bodies 11 and 11 'having the same shape from the upper and lower directions. It has become.
[0018]
Moreover, as shown in FIG. 3, each latching | locking part 14 provided in the front 11d of the connection box main body 11 is provided with the latching protrusion 14a and the introduction part 14b. Further, each locking portion 15 includes a locking projection 15a, an arm portion 15b, a bent portion 15c, and a support portion 15d. The locking projection 15a is deformed in the direction of arrow A in FIG. The arm portion 15b and the bent portion 15c are disposed so as to be supported by the support portion 15d.
[0019]
Note that a locking portion 30 for mounting the connector 40 is integrally formed on the back surface 11e of the connection box main body 11, and the connector 40 is retrofitted to the locking portion 30.
[0020]
Next, the coupling | bonding operation | movement of this electrical junction box 10 is demonstrated using Fig.4 (a) and FIG.4 (b). In order to couple the two junction box bodies 11 and 11 ′ through the pair of engaging portions 12 and 13 and the pair of locking portions 14 and 15, the junction box is connected in the direction of arrow B in FIG. When the body 11 'is slid, the locking projection 15a of the junction box body 11 interferes with the introduction portion 14b of the mating junction box body 11', but the arm portion 15b and the bent portion 15c of the junction box body 11 are bent. Due to the deformation, the locking projection 15a moves to the support portion 15d side, so that the locking projection 15a rides on the locking portion 14 and the coupling work is not hindered.
[0021]
Further, the locking projection 14a of the junction box body 11 interferes with the arm portion 15b of the mating junction box body 11 ', but this also causes the arm portion 15b and the bent portion 15c of the mating junction box body 11' to bend. As a result of the deformation, the locking projection 15a of the mating junction box body 11 'moves to the support portion 15d side, so that the coupling operation is not hindered. When the coupling operation further proceeds, the locking projection 14a of the connection box body 11 that has interfered with the arm portion 15b of the mating connection box body 11 'becomes the locking projection 15a of the mating connection box body 11'. However, since the interference surfaces of the locking projections 14a and 15a are provided obliquely with respect to the coupling direction, as the coupling operation proceeds, the arm portion of the mating junction box body 11 ' 15b and the bent portion 15c are further bent and deformed, and the locking projection 15a gets over the locking projection 14a.
[0022]
FIG. 4B shows this state. In the state of FIG. 4 (b), even if the other side (shaded side) connection box body 11 'is further pushed downward in the figure, the locking projection 15a of the connection box body 11 is moved to the other side connection box. It becomes a stopper of the latching protrusion 14a of the main body 11 'and can prevent the two junction box main bodies 11, 11' from falling off. Further, even if an attempt is made to pull out the mating junction box body 11 'upward in the drawing, the latching projection 14a of the junction box body 11 locks the latching projection 15a of the mating junction box body 11' and Since it is possible to prevent the junction box bodies 11 and 11 'from falling off, the coupling state of the two electrical junction boxes 10 and 10 is maintained, and the coupling is completed.
[0023]
4 (a) and 4 (b) show the case where the mating junction box body 11 'is coupled from above in the figure, the mating junction box body 11' is coupled from below in the figure. Even so, since the pair of locking portions 14 and 15 perform the same operation as described above, the two electrical junction boxes 10 and 10 can be combined.
[0024]
Further, when a pair of engaging portions 12 and 13 and a pair of left and right engaging portions 14 and 15 are arranged so that two electric junction boxes 10 and 10 having the same shape are coupled, two electric junction boxes having the same shape are arranged. When the joints 10 and 10 are joined, the upper surfaces 11c of the junction box bodies 11 and 11 'have the same height, and a pair of engaging portions 12 and 13 and a pair of left and right engaging portions 14 and 15 are disposed. Depending on the position, the side surfaces of the junction box bodies 11, 11 ′ can be set to the same position.
[0025]
In other words, since the coupling structure of this embodiment is provided with all the components of the coupling structure on one side of the junction box body, the coupling part has the same shape as the mating side, so it can be manufactured with one mold. The cost of mold production can be reduced by simplifying the mold shape. Furthermore, since electrical junction boxes having the same shape can be combined, a highly versatile electrical junction box can be manufactured. Further, it is possible to reduce the manufacturing cost by reducing the size by eliminating the need for providing a connection structure that is not used for the connection, and by reducing the raw materials associated therewith.
[0026]
Furthermore, in the coupling structure of the present embodiment, by providing the locking projections that hold the locking state in the vertical direction, the electrical connection box can be coupled from two directions. Is improved.
[0027]
Moreover, since the latching | locking part 30 is arrange | positioned in the back surface 11e of the junction box main body 11, and it becomes possible to attach the connector 40, since the several connector 40 is collected in the electrical junction box 10, the inspection of an electric system, Workability such as repair is improved.
[0028]
The embodiment described above is described for facilitating understanding of the present invention, and does not limit the present invention. Therefore, each element shown in this embodiment is intended to include all design choices that fall within the technical scope of the present invention.
[0029]
For example, in the present embodiment, the pair of engaging portions 12 and 13 are disposed so as to sandwich the pair of left and right engaging portions 14 and 15, but the engaging portions 14 and 15 are engaged with the engaging portions 12 and 13. You may arrange | position so that may be pinched | interposed. In addition, depending on the position where the pair of engaging portions 12 and 13 and the pair of left and right engaging portions 14 and 15 are disposed, the connection box main bodies 11 and 11 ′ are adapted to fit the space of the vehicle body to which the electric connection box 10 is attached. It is also possible to shift the sides of the two.
[0030]
Furthermore, in the present embodiment, the pair of engaging portions 12 and 13 and the pair of left and right engaging portions 14 and 15 are formed of separate members, but the engaging portions 12 and 13 are provided with a locking function. Alternatively, the engaging portions 14 and 15 may be provided with an engaging function and the respective portions may be disposed.
