Description

本発明は、収容対象物の接続構造、電気接続箱及びワイヤハーネスに関する。   The present invention relates to a connection structure of an object to be accommodated, an electrical connection box, and a wire harness.

従来、収容対象物と収容箱とを接続するための接続構造が知られている。その接続構造は、挿入された収容対象物を収容箱の収容完了位置で係止させる係止機構を備える。その係止機構は、収容対象物と収容箱とに各々設けた係止体を備えている。それぞれの係止体は、各々、収容完了位置で収容対象物と収容箱との間の抜去方向の動きを係止し得る爪部等の係止部と、収容完了位置まで収容対象物を案内するガイドレールと、を有する。この種の接続構造は、例えば、下記の特許文献１及び２に開示されている。   DESCRIPTION OF RELATED ART Conventionally, the connection structure for connecting an accommodation target object and a storage box is known. The connection structure includes a locking mechanism that locks the inserted storage object at the storage completion position of the storage box. The locking mechanism includes locking members respectively provided on the storage target and the storage box. Each locking body guides the storage subject to the storage completion position and a locking portion such as a claw portion that can lock the movement in the removal direction between the storage target and the storage box at the storage completion position. And a guide rail. This type of connection structure is disclosed, for example, in Patent Documents 1 and 2 below.

特開平１０−７０８１１号公報Japanese Patent Application Laid-Open No. 10-70811 特開２００４−７２９４１号公報JP 2004-72941 A

ところで、収容対象物と収容箱は、合成樹脂で成形されるものであり、相互間の挿抜方向における何れか一方向に沿うように金型からの抜き取り方向が設定されている。また、収容対象物と収容箱は、係止体と共に成形されるので、金型からの抜き取り方向がガイドレールの延在方向（収容対象物の案内方向）に沿うように設定されている。よって、収容対象物と収容箱の壁面や端面等には、その抜き取り方向に沿う微小の傾斜角度で金型の抜き勾配が設けられている。その壁面や端面等は、金型の抜き勾配に応じて傾いた傾斜面となる。ここで、収容対象物は、自らの形状についても金型からの抜き取り方向を決める際の要素となるので、収容箱への挿入方向に抜き取られるものもあれば、収容箱からの抜去方向に抜き取られるものもある。金型からの抜き取り方向は、これと同様に、収容箱についても自らの形状に依存して決まる。よって、互いに案内し合うガイドレール同士においては、必ずしも双方の傾斜面が平行な状態で対向配置されるとは限らず、それぞれの傾斜面の間の各位置での隙間に大小の差が生じている可能性がある。例えば、それぞれの傾斜面は、互いに逆向きに傾いた状態で対向配置されている場合、相互間の各位置での隙間に大小の差が生じてしまう。また、それぞれの傾斜面は、互いに同じ向きに傾いた状態で対向配置されていたとしても、その傾斜角度が違うものであれば、相互間の各位置での隙間に大小の差が生じてしまう。故に、従来の係止機構においては、係止体同士を挿入及び嵌合させることができたとしても、それぞれのガイドレールの傾斜面の間でがたつきを発生させてしまう虞がある。また、従来の係止機構においては、収容対象物が収容完了位置に到達する前にそれぞれのガイドレールの傾斜面同士が当接し、係止体同士の挿入作業性を低下させてしまう虞がある。   By the way, the object to be accommodated and the container box are formed of synthetic resin, and the extraction direction from the mold is set along any one of the insertion and extraction directions between them. Further, since the storage object and the storage box are molded together with the locking member, the removal direction from the mold is set to be along the extending direction of the guide rail (the guiding direction of the storage object). Therefore, the draft of the mold is provided on the wall surface, the end face, and the like of the storage object and the storage box at a minute inclination angle along the extraction direction. The wall surface, the end surface, etc. become an inclined surface inclined according to the draft of the mold. Here, since the storage object is an element in determining the removal direction from the mold also in its own shape, some may be removed in the insertion direction to the storage box, and may be removed in the removal direction from the storage box There are also The direction of removal from the mold likewise depends on the shape of the storage box. Therefore, in the guide rails that guide each other, the two inclined surfaces are not necessarily disposed opposite to each other in a parallel state, and a large or small difference occurs in the gap at each position between the respective inclined surfaces. There is a possibility. For example, when the respective inclined surfaces are disposed to face each other in a state of being inclined in the opposite direction to each other, large and small differences may occur in the gap at each position between them. In addition, even if the inclined surfaces are arranged opposite to each other in the same direction, if the inclination angles are different, large and small differences may occur in the gap at each position between them. . Therefore, in the conventional locking mechanism, even if the locking members can be inserted and fitted, rattling may occur between the inclined surfaces of the respective guide rails. Moreover, in the conventional locking mechanism, there is a possibility that the inclined surfaces of the respective guide rails abut against each other before the storage target reaches the storage completion position, and the insertion workability of the locking members may be reduced. .

そこで、本発明は、挿入作業性を向上させつつがたつきを抑え得る収容対象物の接続構造、電気接続箱及びワイヤハーネスを提供することを、その目的とする。   Then, this invention makes it the objective to provide the connection structure of an accommodation target object, an electric connection box, and a wire harness which can suppress rattle while improving insertion workability.

The guide surfaces of the third and fourth guide rails are formed so as to be opposed to each other in the state, so that the accommodation objects are arranged to be opposed in parallel with each other when the accommodation completion position is established.

The inclination angles of all the guide surfaces are further determined by the third and fourth gaps between the guide surfaces of the first and second guide rails when the storage target is at the storage completion position. The total value of the gaps between the guide surfaces of the guide rails is 0.6 mm or more, and the distance between the guide surface of each of the second and fourth guide rails at the insertion opening and the insertion opening are reached It is preferable to set the difference in the distance between the guide surface of each of the first and third guide rails at the insertion opening to 2 mm or less.

Therefore, in this locking mechanism, the insertion opening can easily pick up the tips of the first and third guide rails. Therefore, since this locking mechanism is excellent in the insertion workability between the first locking body side and the second locking body side, the insertion workability of the storage target into the storage box is improved. be able to. Furthermore, this locking mechanism narrows the gap formed by the first and third guide rails on the first locking body side and the second and fourth guide rails on the second locking body side in the housing complete position. You can do it, and you can control backlash. As described above, in the connection structure of the storage target according to the present invention, the operation of inserting each other when the first locking body side and the second locking body side start to be engaged is easily performed. Furthermore, in this connection structure, when the first locking body and the second locking body can be locked, the first and third guide rails and the second guiding rail on the first locking body side can be used.

更に、全てのガイド面３３ａ，３４ａ，３５ａ，３６ａは、第１及び第２の係止体３１，３２並びに第１から第４のガイドレール３３−３６における金型の抜き勾配よりも大きく、かつ、対となるガイドレール同士（第１及び第２のガイドレール３３，３４、第３及び第４のガイドレール３５，３６）の案内動作が可能な最大傾斜角度以下の傾斜角度θで傾斜させる（図８及び図９）。例えば、全てのガイド面３３ａ，３４ａ，３５ａ，３６ａの傾斜角度θは、３度以上、１５度以下の範囲内で設定する。尚、ここで云う案内動作が可能な傾斜角度θとは、対となるガイド面同士（ガイド面３３ａ，３４ａ同士、ガイド面３５ａ，３６ａ同士）が互いの壁面に沿って案内し合いながら、電子部品保持体２０Ａを収容完了位置まで到達させることができる角度のことであり、対となるガイド面同士が単に近づいていくだけであったり当接するだけであったりするものを除外する意味を持つ。全てのガイド面３３ａ，３４ａ，３５ａ，３６ａは、次のようにして電子部品保持体２０Ａの挿抜方向に対する傾斜角度θを設定してもよい。   Furthermore, all the guide surfaces 33a, 34a, 35a, 36a are larger than the draft of the mold in the first and second locking members 31, 32 and the first to fourth guide rails 33-36, and , And inclined at an inclination angle θ equal to or less than the maximum inclination angle at which the guide operation between the pair of guide rails (the first and second guide rails 33 and 34 and the third and fourth guide rails 35 and 36) is possible. 8 and 9). For example, the inclination angle θ of all the guide surfaces 33a, 34a, 35a, 36a is set in the range of 3 degrees or more and 15 degrees or less. Here, with the inclination angle θ at which the guide operation mentioned here is possible, the guide surfaces (a pair of guide surfaces 33a and 34a, a pair of guide surfaces 35a and 36a) guiding each other are guided along the wall surfaces. It is an angle at which the component holder 20A can reach the accommodation completion position, and it has a meaning of excluding the one in which the guide surfaces which are the pair are merely approaching or abutting. Of all the guide surfaces 33a, 34a, 35a, 36a may be set with respect to the insertion / removal direction of the electronic component holder 20A as follows.

例えば、ここでは、第２及び第４のガイドレール３４，３６におけるそれぞれのガイド面３４ａ，３６ａの挿入口３７での間隔Ｓ１と、その挿入口３７に到達した第１及び第３のガイドレール３３，３５におけるそれぞれのガイド面３３ａ，３５ａの挿入口３７での間隔Ｓ２（＜Ｓ１）と、を利用する（図１０）。更に、ここでは、電子部品保持体２０Ａが収容完了位置のときのガイド面３３ａ，３４ａ同士の隙間Ｇ１｛＜（Ｄ１／２）｝と、電子部品保持体２０Ａが収容完了位置のときのガイド面３５ａ，３６ａ同士の隙間Ｇ２｛＜（Ｄ１／２）｝と、を利用する（図７）。その隙間Ｇ１，Ｇ２は、電子部品保持体２０Ａが収容完了位置に配置されているときの隙間であり、電子部品保持体２０Ａの挿抜方向に対する直交方向に沿う同じ大きさのものとする。全てのガイド面３３ａ，３４ａ，３５ａ，３６ａの傾斜角度θは、それぞれの隙間Ｇ１，Ｇ２の合計値が所定の大きさ（例えば、０．６ｍｍ）以上で、かつ、間隔Ｓ１と間隔Ｓ２との差Ｄ１（＝Ｓ１−Ｓ２）が所定の大きさ（例えば、２ｍｍ）以下で、かつ、例えば第１から第４のガイドレール３３−３６におけるガイド面３３ａ，３４ａ，３５ａ，３６ａ以外の場所の金型の抜き勾配よりも大きく、かつ、対となるガイドレール同士（第１及び第２のガイドレール３３，３４、第３及び第４のガイドレール３５，３６）の案内動作が可能な最大傾斜角度以下となる大きさに設定する。   For example, here, the spacing S1 at the insertion opening 37 of the guide surfaces 34a and 36a of the second and fourth guide rails 34 and 36, and the first and third guide rails 33 reaching the insertion opening 37. , 35 at intervals S2 (<S1) at the insertion openings 37 of the respective guide surfaces 33a, 35a (FIG. 10). Furthermore, here, the gap G1 {<(D1 / 2)} between the guide surfaces 33a and 34a when the electronic component holder 20A is at the housing complete position, and the guide surface when the electronic component holder 20A is at the housing complete position A gap G2 {<(D1 / 2)} between 35a and 36a is used (FIG. 7). The gaps G1 and G2 are gaps when the electronic component holder 20A is disposed at the housing complete position, and have the same size along the direction orthogonal to the insertion and removal direction of the electronic component holder 20A. The inclination angle θ of all the guide surfaces 33a, 34a, 35a, 36a is such that the total value of the respective gaps G1, G2 is equal to or greater than a predetermined size (for example, 0.6 mm) and between the interval S1 and the interval S2. Gold of places other than the guide surfaces 33a, 34a, 35a, 36a in which the difference D1 (= S1-S2) is less than a predetermined size (for example, 2 mm) and in the first to fourth guide rails 33-36. Maximum inclination angle larger than the draft of the die and capable of guiding the pair of guide rails (first and second guide rails 33 and 34, third and fourth guide rails 35 and 36). Set to the following size.

この係止機構３０においては、電子部品保持体２０Ａを収容箱１０へと挿入しているときに、先ず、第１係止体３１側の第１及び第３のガイドレール３３，３５の先端（挿入方向側の先端）が第２係止体３２側の第２及び第４のガイドレール３４，３６の成す挿入口３７に到達する。この係止機構３０においては、その挿入口３７への到達と共に、第１係止体３１側と第２係止体３２側との係合が始まる。この係止機構３０においては、第１係止体３１側と第２係止体３２側との係合が始まるときの間口（挿入口３７）が広く取られている。例えば、この係合が開始したときには、先に示したように、挿入口３７において、差Ｄ１の分だけ隙間が空いている。故に、この係止機構３０においては、挿入口３７が第１及び第３のガイドレール３３，３５の先端を拾い易くなっている。よって、この係止機構３０は、第１係止体３１側と第２係止体３２側との間の挿入作業性に優れたものとなっているので、電子部品保持体２０Ａの収容箱１０への挿入作業性を向上させることができる。また、この係止機構３０は、その間口の広さ故に、電子部品保持体２０Ａが所期の挿入方向に対して傾きながら挿入し始めたとしても、第１係止体３１側の第１及び第３のガイドレール３３，３５と第２係止体３２側の第２及び第４のガイドレール３４，３６との間の噛み込みが発生し難くなっている。よって、この係止機構３０は、電子部品保持体２０Ａの挿入作業をそのまま続けていくことができる。   In the locking mechanism 30, when the electronic component holder 20A is inserted into the storage box 10, first, the tips of the first and third guide rails 33, 35 on the first locking body 31 side ( The leading end on the insertion direction side reaches the insertion opening 37 formed by the second and fourth guide rails 34 and 36 on the second locking body 32 side. In the locking mechanism 30, the engagement between the first locking body 31 side and the second locking body 32 side starts with the arrival at the insertion port 37. In the locking mechanism 30, a gap (insertion port 37) is widely taken when engagement between the first locking body 31 side and the second locking body 32 side starts. For example, when the engagement is started, as described above, in the insertion opening 37, the gap is open by the difference D1. Therefore, in the locking mechanism 30, the insertion opening 37 can easily pick up the tips of the first and third guide rails 33, 35. Therefore, since this locking mechanism 30 is excellent in the insertion workability between the first locking body 31 side and the second locking body 32 side, the storage box 10 of the electronic component holding body 20A. The insertion workability can be improved. In addition, since the locking mechanism 30 is inserted at the same time as the electronic component holder 20A is inclined with respect to the expected insertion direction because of the width of the opening, the first and the first locking body 31 side and the first Biting between the third guide rails 33 and 35 and the second and fourth guide rails 34 and 36 on the second locking member 32 side is less likely to occur. Therefore, the locking mechanism 30 can continue the insertion work of the electronic component holder 20A as it is.

続いて、この係止機構３０においては、電子部品保持体２０Ａの収容箱１０への挿入作業が進行し、電子部品保持体２０Ａが収容完了位置に到達することによって、第１係止体３１と第２係止体３２とが係止可能な状態となる。その収容完了位置では、第２及び第４のガイドレール３４，３６のガイド面３４ａ，３６ａの間隔Ｓ３と第１及び第３のガイドレール３３，３５のガイド面３３ａ，３５ａの間隔Ｓ４（＜Ｓ３）との間に差Ｄ２（＝Ｓ３−Ｓ４）が生じている（図７）。その間隔Ｓ３，Ｓ４は、電子部品保持体２０Ａの挿抜方向に対する直交方向に沿うものである。収容完了位置では、挿抜方向における各位置で間隔Ｓ３，Ｓ４が異なるが、その各位置で差Ｄ２が同じ大きさになっている。その差Ｄ２は、先に示した隙間Ｇ１，Ｇ２の合計値を表している。つまり、収容完了位置では、第１係止体３１側の第１及び第３のガイドレール３３，３５と第２係止体３２側の第２及び第４のガイドレール３４，３６とが成す隙間（隙間Ｇ１，Ｇ２の合計値）が狭められており、その間のがたつきを抑えることができる。   Subsequently, in the locking mechanism 30, the insertion work of the electronic component holder 20A into the storage box 10 proceeds, and the electronic component holder 20A reaches the storage completion position, thereby the first locking member 31 and It will be in the state which can be latched with the 2nd latching body 32. FIG. In the housing complete position, the distance S3 between the guide surfaces 34a and 36a of the second and fourth guide rails 34 and 36 and the distance S4 between the guide surfaces 33a and 35a of the first and third guide rails 33 and 35 (<S3 ) And a difference D2 (= S3-S4) has occurred (FIG. 7). The intervals S3 and S4 are along the direction orthogonal to the insertion and removal direction of the electronic component holder 20A. At the storage completion position, the intervals S3 and S4 are different at each position in the insertion and removal direction, but the difference D2 is the same size at each position. The difference D2 represents the total value of the gaps G1 and G2 shown above. That is, in the housing complete position, a gap formed by the first and third guide rails 33 and 35 on the first locking body 31 side and the second and fourth guide rails 34 and 36 on the second locking body 32 side. (The total value of the gaps G1 and G2) is narrowed, and rattling can be suppressed.

以上示したように、本実施形態の収容対象物２０の接続構造においては、第１係止体３１側と第２係止体３２側とが係合し始めるときの互いの挿入作業が行われ易くなっている。更に、この接続構造においては、第１係止体３１と第２係止体３２とが係止可能な状態になっているときに、第１係止体３１側の第１及び第３のガイドレール３３，３５と第２係止体３２側の第２及び第４のガイドレール３４，３６との間のがたつきが抑制されている。従って、この接続構造は、収容対象物２０（電子部品保持体２０Ａ）の収容箱１０への挿入作業性を向上させつつ、この収容対象物２０と収容箱１０との間のがたつきを抑えることができる。また、本実施形態の電気接続箱１とワイヤハーネスＷＨは、その接続構造を備えるものであるので、その接続構造の効果を奏することができる。   As described above, in the connection structure of the storage object 20 of the present embodiment, the insertion work is performed when the first locking body 31 side and the second locking body 32 side start to be engaged. It is easier. Furthermore, in this connection structure, when the first locking body 31 and the second locking body 32 are in the lockable state, the first and third guides on the first locking body 31 side are provided. A rattling between the rails 33 and 35 and the second and fourth guide rails 34 and 36 on the second locking body 32 side is suppressed. Therefore, this connection structure suppresses rattling between the storage object 20 and the storage box 10 while improving the workability of inserting the storage object 20 (the electronic component holder 20A) into the storage box 10. be able to. Moreover, since the electrical connection box 1 and the wire harness WH of this embodiment are provided with the connection structure, the effect of the connection structure can be exhibited.
