Description

本発明は、厳しい使用環境での信頼性が要求される自動車等に、確実に且つ容易に取り付けることが出来る電子部品に関する技術である。   The present invention relates to an electronic component that can be reliably and easily attached to an automobile or the like that is required to be reliable in a severe use environment.

電子部品の多くは、電子機器や電気機器等の電子回路基板や電気回路基板に、はんだ等によって実装、固定して使用されるが、自動車に使用される電子部品は、上記のような電子回路基板や電気回路基板に実装されたものが自動車に搭載される他に、電子部品を単独、あるいは数個の電子部品を一つにまとめて直接エンジンルーム内に取り付け固定するという搭載形態のものもある。このような自動車のエンジンルーム内に取り付けられる電子部品は、厳しい温度や湿度環境における電子部品自体の電気特性の信頼性が要求されると共に、振動や衝撃あるいは温度変化等に対する自動車への取り付けの信頼性も要求されている。   Many electronic components are mounted and fixed on an electronic circuit board or an electric circuit board such as an electronic device or an electric device with solder or the like, but an electronic component used in an automobile is an electronic circuit as described above. In addition to being mounted on a board or an electric circuit board, it can be mounted on an automobile, or electronic parts can be mounted individually or several electronic parts can be directly mounted and fixed in the engine compartment. is there. Such electronic parts installed in the engine compartment of automobiles require reliability of the electrical characteristics of the electronic parts themselves in severe temperature and humidity environments, and reliability of installation in automobiles against vibrations, shocks or temperature changes. Sex is also required.

本発明はこのような厳しい環境で使用される電子部品の取り付け形態に関するものである。
図１１は従来の電子部品１０１および取付板１０５を示す。 The present invention relates to an electronic component mounting form used in such a severe environment.
FIG. 11 shows a conventional electronic component 101 and a mounting plate 105.

樹脂製の収納部１０３には、先端に接続端子１１４を有するリード線１１３が接続された電子部品素子（図示せず）が収められ、充填樹脂１１５が充填されている。
電子部品１０１を自動車の車体に取り付けるための取付板１０５は、主に平板形状の鋼材に耐食性を持たせるために、錫や亜鉛等のメッキあるいは塗装を施したものである。 An electronic component element (not shown) to which a lead wire 113 having a connection terminal 114 is connected at the tip is stored in a resin storage portion 103 and is filled with a filling resin 115.
The mounting plate 105 for mounting the electronic component 101 to the automobile body is obtained by plating or coating tin, zinc or the like in order to give corrosion resistance to a mainly flat steel material.

この取付板１０５の電子部品１０１への取り付け状態は、収納部１０３の外壁１１０と、収納部１０３の外壁１１０に収納部１０３と同じ材料で一体成型により形成された取付板保持部１０４ａ，１０４ｂとの間に嵌め込まれており、収納部１０３の外壁１１０に備えられた突起部１０６が、取付板１０５に設けられた貫通孔１０９に嵌入し固定されている。そして、取付板１０５に備えた孔１１６にボルトを通し、締め付けることによって自動車の車体に取り付けられる。   The mounting state of the mounting plate 105 to the electronic component 101 includes an outer wall 110 of the storage unit 103, and mounting plate holding units 104 a and 104 b formed by integral molding on the outer wall 110 of the storage unit 103 with the same material as the storage unit 103. The projection 106 provided on the outer wall 110 of the storage unit 103 is fitted into and fixed to the through hole 109 provided in the mounting plate 105. And it attaches to the vehicle body of a motor vehicle by passing a bolt through the hole 116 provided in the mounting plate 105 and tightening it.

このとき、取付板１０５を平板形状としているので、取り付け位置周辺のエンジンルームの形状や、他の搭載部品の取り付け位置に応じて、取付板１０５の車体に接する面（図１１におけるＤ面とＥ面）を選択することによって、形状の異なる取付板を新たに用意することなく電子部品１０１の取り付け方向を変えることが出来る。このような従来の電子部品に関連する先行技術文献としては、例えば特許文献１が知られている。
特開２０００−３３１８６８号公報 At this time, since the mounting plate 105 has a flat plate shape, the surface of the mounting plate 105 that contacts the vehicle body (D surface and E in FIG. 11) according to the shape of the engine room around the mounting position and the mounting position of other mounted components. By selecting (Surface), the mounting direction of the electronic component 101 can be changed without newly preparing a mounting plate having a different shape. As a prior art document related to such a conventional electronic component, for example, Patent Document 1 is known.
JP 2000-331868 A

例えば、雑音防止用として自動車のエンジンルーム内に搭載されるフィルムコンデンサの場合、従来は静電容量が大きくても０．４〜２．２μＦ程度であったものが、近年は２０μＦを超える高容量のものが必要とされることがあり、重量も従来は１０〜２０ｇであったものが１００〜１２０ｇと重くなってきており、上記のような従来の取り付け形態では取付板の剛性が不十分になり、自動車への取り付け状態に不具合を生じることがある。   For example, in the case of a film capacitor mounted in an engine room of an automobile for noise prevention, a conventional capacitor having a large capacitance of about 0.4 to 2.2 μF has been recently used. In the conventional mounting configuration as described above, the rigidity of the mounting plate is insufficient. Therefore, a problem may occur in the mounting state of the vehicle.

その対策として、取付板１０５の厚みを厚くしたり、幅を広くしたりして剛性を高くすることが考えられるが、このような方法では剛性は確保できるものの、単純に取付板１０５の断面積を１０倍にしなければならないことになり、このような大型化した取付板１０５は、形状的にまた取付板１０５を加工するためのプレス機を大型化するための設備費の増大や、金型費の増大等、製造コスト的に実際に採用できるものではなかった。   As a countermeasure, it is conceivable to increase the rigidity by increasing the thickness of the mounting plate 105 or by increasing the width. However, although such a method can ensure the rigidity, the cross-sectional area of the mounting plate 105 is simply obtained. The size of the mounting plate 105 that has been increased is increased in equipment cost for increasing the size of the press machine for processing the mounting plate 105 in terms of shape and mold. It could not be used in terms of manufacturing cost due to increased costs.

また、取付板１０５に補強のリブを設けることで取付板１０５の大型化を抑えながら剛性を確保することが考えられる。
ところが取付板１０５にリブを設けると、リブを設けた面を自動車の車体に接するような取り付け方をした場合、以下のような問題が生じる。 In addition, it is conceivable to provide rigidity while suppressing the enlargement of the mounting plate 105 by providing reinforcing ribs on the mounting plate 105.
However, when ribs are provided on the mounting plate 105, the following problems arise when the mounting method is performed so that the surface on which the ribs are provided contacts the vehicle body.

それは、このような取り付け方をすると、取付板１０５に設けたリブの部分だけしか自動車の車体と接触しなくなってしまい、取付板と車体との接触面積が著しく小さくなり、取り付けの強度が不足する。   If this is the case, only the rib portion provided on the mounting plate 105 will be in contact with the vehicle body, the contact area between the mounting plate and the vehicle body will be significantly reduced, and the mounting strength will be insufficient. .

そのため、取付板１０５の車体に接する面を変えることによって電子部品１０１の取り付け方向を変えるということが出来なくなり、その結果、電子部品１０１の取り付け方向を変えるためには、形状の異なる取付板１０５を新たに用意しなければならないという問題がある。   Therefore, it becomes impossible to change the mounting direction of the electronic component 101 by changing the surface of the mounting plate 105 that contacts the vehicle body. As a result, in order to change the mounting direction of the electronic component 101, the mounting plate 105 having a different shape is used. There is a problem that a new one has to be prepared.

本発明は、重量のある部品であっても確実に保持することができ、しかも被装着面に対する電子部品の取り付け方向を変更できる電子部品を提供することを目的とする。   An object of the present invention is to provide an electronic component that can reliably hold even a heavy component and can change the mounting direction of the electronic component with respect to the mounting surface.

本発明の電子部品は、電子部品素子が収納された収納部と、前記収納部の外壁に設けられた結合部と、前記結合部に嵌め込まれて結合された取付板とを備えた電子部品であって、前記結合部が断面方形となる空洞部を形成する壁部を有し、前記取付板には、取付板５の一方の面に向かって折り曲がった形状の突出し部と、係合用の孔または凹部を設け、前記取付板に設けた前記孔または凹部に嵌入する凸部を前記結合部を構成する壁部に対向して設けたことを特徴とする。   An electronic component according to the present invention is an electronic component including a storage portion in which an electronic component element is stored, a coupling portion provided on an outer wall of the storage portion, and a mounting plate that is fitted into and coupled to the coupling portion. The coupling portion has a wall portion forming a hollow portion having a square cross section, and the mounting plate includes a protruding portion bent into one surface of the mounting plate 5 and an engaging portion. A hole or a concave portion is provided, and a convex portion that fits into the hole or the concave portion provided in the mounting plate is provided to face a wall portion that constitutes the coupling portion.

この構成によれば、電子部品が大型化し重量が増加しても、取付板の大型化を抑えながら取付板の剛性を高くすると共に、形状の異なる取付板を用意することなく簡単に電子部品の取り付け方向を変えることが出来るので、電子部品の自動車への取り付けの信頼性の確保と、コスト上昇を抑えるという効果が得られる。   According to this configuration, even if the electronic component becomes large and increases in weight, the rigidity of the mounting plate is increased while suppressing the increase in size of the mounting plate, and the electronic component can be easily manufactured without preparing a mounting plate having a different shape. Since the mounting direction can be changed, it is possible to obtain the effects of securing the reliability of mounting the electronic component on the automobile and suppressing the cost increase.

以下、本発明の電子部品を図１〜図１０に基づいて説明する。

(Embodiment 1)

It is a perspective view of the electronic component element 2 which concerns on Embodiment 1 of this invention.

図１において、電子部品１は、収納部３と、結合部４と、取付板５とからなる。樹脂製の収納部３には、図４に示す電子部品素子２を収納して充填樹脂１５でモールドされている。具体的には、本実施の形態では電子部品素子２はフィルムコンデンサ素子であって、電子部品素子２に接続されたリード線１３が、先端に接続端子１４を有する端部が収納部３の外に出るように収納されている。   In FIG. 1, the electronic component 1 includes a storage portion 3, a coupling portion 4, and a mounting plate 5. In the resin storage part 3, the electronic component element 2 shown in FIG. 4 is stored and molded with a filling resin 15. Specifically, in the present embodiment, the electronic component element 2 is a film capacitor element, and the lead wire 13 connected to the electronic component element 2 has an end portion having a connection terminal 14 at the tip thereof outside the storage portion 3. It is stored so that it may come out.

収納部３の外周面に壁部１１ａを一体成形して形成されている結合部４は、開口部１２が収納部３の外周面との間に形成された方形で、結合部４の深さ方向に空洞部１７が形成されており、金属製の取付板５は、開口部１２から空洞部１７に嵌め込まれ結合されている。   The coupling portion 4 formed by integrally molding the wall portion 11 a on the outer peripheral surface of the storage portion 3 is a square in which the opening 12 is formed between the outer peripheral surface of the storage portion 3 and the depth of the coupling portion 4. A hollow portion 17 is formed in the direction, and the metal mounting plate 5 is fitted into the hollow portion 17 through the opening 12 and coupled thereto.

詳しく説明すると、図２，図３において、ポリブチレンテレフタレートやポリカーボネート等の樹脂製の収納部３の外壁１０には断面方形の空洞部１７を有する結合部４が収納部３側の壁部１１ａを、収納部３の結合部４側の外壁１０の一部と共有する形で収納部３と同じ材料で設けられ、上端に開口部１２を有し、下端は閉じている。   More specifically, in FIG. 2 and FIG. 3, the connecting portion 4 having a hollow portion 17 having a square cross section is formed on the outer wall 10 of the resin storage portion 3 such as polybutylene terephthalate or polycarbonate. The storage portion 3 is provided with the same material as the storage portion 3 so as to be shared with a part of the outer wall 10 on the coupling portion 4 side, has an opening 12 at the upper end, and is closed at the lower end.

そして、結合部４の空洞部１７を形成する壁部１１ａの内面の幅方向（図２における上下方向）の中央で且つ取付板５が挿入される方向の中央部には、高さが取付板５の厚みと略等しい円柱状の凸部６ａが設けられ、更に壁部１１ａと対向する壁部１１ｂの内面にも、凸部６ａと同じ寸法、同じ形状の凸部６ｂが、壁部１１ａに対する凸部６ａの位置関係と同じ位置関係、すなわち凸部６ａに真正面に対向するように設けられている。   Then, the height of the attachment plate 5 is at the center in the width direction (vertical direction in FIG. 2) of the inner surface of the wall portion 11a forming the cavity portion 17 of the coupling portion 4 and in the direction in which the attachment plate 5 is inserted. 5 is provided, and a convex portion 6b having the same size and shape as the convex portion 6a is provided on the inner surface of the wall portion 11b opposite to the wall portion 11a with respect to the wall portion 11a. The same positional relationship as that of the convex portion 6a, that is, the convex portion 6a is provided so as to face the front.

取付板５は、鋼材に防錆のための錫や亜鉛等のメッキあるいは塗装が施されており、幅方向（図２における上下方向）の両端には、突出し部７が、取付板５の幅方向の両端部を取付板５の一方の面に向かって略直角に折り曲げることによって、突出し部７の長辺が空洞部１７への挿入方向（図３における上下方向）に略平行に、挿入方向における一方の端面から他方の端面に亘って設けられている。この突出し部７を設けることによって取付板５の剛性を高くしている。   The mounting plate 5 has a steel material plated or coated with tin, zinc or the like for rust prevention, and projecting portions 7 are provided at both ends in the width direction (vertical direction in FIG. 2) of the mounting plate 5. By bending both end portions in the direction toward one surface of the mounting plate 5 at a substantially right angle, the long side of the protruding portion 7 is substantially parallel to the insertion direction (vertical direction in FIG. 3) into the cavity portion 17. Are provided from one end face to the other end face. By providing the protruding portion 7, the rigidity of the mounting plate 5 is increased.

そして取付板５には、空洞部１７へ挿入される部分の挿入方向の中央で且つ幅方向の中央部に、円形で、その直径が壁部１１ａ，１１ｂに設けられた凸部６ａ，６ｂが嵌入できるように凸部６ａ，６ｂの直径よりも若干大きい孔９が設けられている。   The mounting plate 5 has convex portions 6a and 6b that are circular and have diameters provided on the wall portions 11a and 11b in the center in the insertion direction of the portion to be inserted into the cavity portion 17 and in the center portion in the width direction. A hole 9 slightly larger than the diameter of the projections 6a and 6b is provided so that it can be inserted.

また、取付板５の突出し部７を設けた面の反対側の面の、取付板５を結合部４へ挿入するときの先端部分の角を切り落として傾斜部１９としている。更に、取付板５の一端には、自動車の車体等の被装着体へ取り付けるための取り付け部１６として、本実施の形態ではボルトで取り付けられるように貫通孔が設けられている。   Further, the inclined portion 19 is formed by cutting off the corner of the tip of the mounting plate 5 on the opposite side of the surface where the protruding portion 7 is provided when the mounting plate 5 is inserted into the coupling portion 4. Furthermore, a through hole is provided at one end of the mounting plate 5 so as to be mounted with a bolt in the present embodiment as a mounting portion 16 for mounting to a mounted body such as a car body of an automobile.

ここで取付板５は、以下のようにして結合部４に結合されている。
取付板５を結合部４の開口部１２から空洞部１７に挿入し、その先端が凸部６ｂに達した後も傾斜部１９によりスムーズに挿入が続けられ、壁部１１ｂが外側へ撓むとともに凸部６ｂが外側に逃げ、取付板５は更に奥に挿入される。そして取付板５の孔９と結合部４の凸部６ｂとが一致すると、孔９に凸部６ｂが嵌入し、取付板５は結合部４に結合される。 Here, the mounting plate 5 is coupled to the coupling portion 4 as follows.
The mounting plate 5 is inserted into the cavity portion 17 from the opening portion 12 of the coupling portion 4, and after the tip reaches the convex portion 6b, the insertion is continued smoothly by the inclined portion 19, and the wall portion 11b bends outward and protrudes. The part 6b escapes to the outside, and the mounting plate 5 is inserted further into the back. And if the hole 9 of the attachment plate 5 and the convex part 6b of the coupling | bond part 4 correspond, the convex part 6b will fit in the hole 9, and the attachment board 5 will be couple | bonded with the coupling | bond part 4. FIG.

このように、取付板５の突出し部７の突出し方向を収納部３側とした場合には、取付板５の突出し部７が突出している面の反対側の面を自動車の車体に接するように取り付けられるので、収納部３が取付板５の車体側の面とは反対側の面に位置するように電子部品１が取り付けられる。   In this way, when the protruding direction of the protruding portion 7 of the mounting plate 5 is the storage portion 3 side, the surface opposite to the surface from which the protruding portion 7 of the mounting plate 5 protrudes is in contact with the vehicle body of the automobile. Since it is attached, the electronic component 1 is attached so that the storage part 3 is located on the surface of the attachment plate 5 opposite to the surface on the vehicle body side.

次に、収納部３が取付板５の車体側の面になるように電子部品１を取り付ける場合について、図５と図６を参照しながら説明する。
図５は電子部品１の平面図、図６は電子部品１の断面図で、取付板５の突出し部７の突出し方向を収納部３の反対方向になるように取付板５を結合した状態を示している。図５，図６において、取付板５は開口部１２から空洞部１７に挿入され、取付板５の孔９に結合部４の凸部６ａが嵌入することにより結合されている。 Next, the case where the electronic component 1 is mounted so that the storage portion 3 is the surface of the mounting plate 5 on the vehicle body will be described with reference to FIGS. 5 and 6.
FIG. 5 is a plan view of the electronic component 1, and FIG. 6 is a cross-sectional view of the electronic component 1, in which the mounting plate 5 is coupled so that the protruding direction of the protruding portion 7 of the mounting plate 5 is opposite to the storage portion 3. Show. 5 and 6, the mounting plate 5 is inserted into the cavity portion 17 through the opening 12, and is coupled by fitting the convex portion 6 a of the coupling portion 4 into the hole 9 of the mounting plate 5.

このように、取付板５の突出し部７の突出し方向を収納部３の反対側になるようにすると、取付板５を突出し部７が突出している面の反対側の面を自動車の車体に接するように取り付けられるので、収納部３が取付板５の車体側の面と同じ面に位置するように電子部品１を取り付けることが出来る。   As described above, when the protruding direction of the protruding portion 7 of the mounting plate 5 is opposite to the housing portion 3, the surface opposite to the surface from which the mounting plate 5 protrudes and the portion 7 protrudes is in contact with the vehicle body. Therefore, the electronic component 1 can be attached so that the storage portion 3 is positioned on the same surface as the surface of the attachment plate 5 on the vehicle body side.

なお、上記のように収納部３が取付板５の車体側の面と同じ側の面に位置するように電子部品１を取り付ける場合に、先に電子部品素子２と充填樹脂１５とを収納部３に収納し充填樹脂１５を硬化させてしまうと、その後に取付板５を挿入しようとした場合、硬化した充填樹脂１５が邪魔をして、結合部４の収納部３側の壁部１１ａが収納部３側に撓まなくなり、取付板５を規定の位置まで挿入できなくなる。そして取付板５を無理に挿入しようとすると、充填樹脂１５に異常な応力がかかりクラックを生じたり、充填樹脂１５が電子部品素子２あるいは収納部３の壁からはく離したり、あるいは結合部４を損傷する虞がある。   In addition, when attaching the electronic component 1 so that the accommodating part 3 may be located in the surface on the same side as the vehicle body side surface of the mounting plate 5 as described above, the electronic component element 2 and the filling resin 15 are first accommodated in the accommodating part. 3 and the filling resin 15 is cured, when the mounting plate 5 is inserted thereafter, the cured filling resin 15 interferes with the wall portion 11a on the storage portion 3 side of the coupling portion 4. The attachment plate 5 cannot be inserted to a specified position because it does not bend toward the storage portion 3 side. If the mounting plate 5 is forcibly inserted, abnormal stress is applied to the filling resin 15 to cause cracks, the filling resin 15 is peeled off from the wall of the electronic component element 2 or the housing portion 3, or the coupling portion 4 is removed. There is a risk of damage.

従って、取付板５の突出し部７の突出し方向を収納部３の反対側とする場合には、先に取付板５を結合部４に挿入し、後から充填樹脂１５を収納部３に充填し硬化するという手順になる。   Therefore, when the protruding direction of the protruding portion 7 of the mounting plate 5 is the opposite side of the storage portion 3, the mounting plate 5 is first inserted into the coupling portion 4, and the filling resin 15 is subsequently filled into the storage portion 3. The procedure is to cure.

このように本実施の形態では、取付板５に突出し部７を設けることにより、重量や形状を著しく大きくすることなく取付板５の剛性を高くすることが出来るので、大型化し重量が増加した電子部品１でも取り付けの信頼性を確保することが可能となる。そして、取付板５の一方の面に突出し部７を設けても、結合部４の空洞部１７を断面方形とし、対向する壁部１１ａ，１１ｂの内面に夫々凸部６ａ，６ｂを設けることによって、自動車の車体等の被装着体へ取り付ける向きを変更する場合であっても、異なる形状の取付板５を新たに設計、製作することなく、電子部品１の収納部３の取り付け方向を取付板５が平板の場合と同じように、一つの形状の取付板５で二通りの取り付け方向に対応することを可能とするものである。   As described above, in the present embodiment, by providing the protruding portion 7 on the mounting plate 5, the rigidity of the mounting plate 5 can be increased without significantly increasing the weight and shape, so that the electronic device is increased in size and weight. It is possible to ensure the mounting reliability of the component 1 as well. And even if the protruding portion 7 is provided on one surface of the mounting plate 5, the cavity portion 17 of the coupling portion 4 has a square cross section, and the convex portions 6a and 6b are provided on the inner surfaces of the opposing wall portions 11a and 11b, respectively. Even when the direction of attachment to a mounted body such as a car body of an automobile is changed, the attachment direction of the storage portion 3 of the electronic component 1 can be changed without newly designing and manufacturing the attachment plate 5 having a different shape. As in the case where 5 is a flat plate, the mounting plate 5 having a single shape can correspond to two mounting directions.

（実施の形態２）
図７は本発明の実施の形態２に係る電子部品４１の平面図、図８は本発明の実施の形態２に係る電子部品４１の断面図である。 (Embodiment 2)
7 is a plan view of the electronic component 41 according to Embodiment 2 of the present invention, and FIG. 8 is a cross-sectional view of the electronic component 41 according to Embodiment 2 of the present invention.

図７，図８において、電子部品４１は、収納部４３と、結合部４４と、金属製の取付板４５とからなり、樹脂製の収納部４３には、電子部品素子４２が収納され、この電子部品素子４２を埋めるように充填樹脂５５が充填されている。先端に接続端子５４を有し他端が電子部品素子４２に接続されリード線５３は、接続端子５４の側が収納部４３の外に出ている。   7 and 8, the electronic component 41 includes a storage portion 43, a coupling portion 44, and a metal mounting plate 45, and an electronic component element 42 is stored in the resin storage portion 43. Filling resin 55 is filled so as to fill electronic component element 42. The lead terminal 53 has a connection terminal 54 at the tip and the other end is connected to the electronic component element 42, and the lead wire 53 has the connection terminal 54 side protruding out of the storage portion 43.

そして、取付板４５は結合部４４の空洞部５７に、この結合部４４に設けられた開口部５２から嵌め込まれ結合されている。取付板４５の一端には、自動車の車体等の被装着体へ取り付けるための取り付け部５６として、本実施の形態ではボルトで取り付けられるように貫通孔が設けられている。   The mounting plate 45 is fitted into and coupled to the hollow portion 57 of the coupling portion 44 from the opening 52 provided in the coupling portion 44. At one end of the mounting plate 45, a through hole is provided as a mounting portion 56 for mounting to a mounted body such as a car body of an automobile so as to be mounted with a bolt in this embodiment.

詳しく説明すると、図７，図８において、樹脂製の収納部４３の外壁５０には断面方形の空洞部を有する結合部４４が収納部４３側の壁部５１ａを、収納部４３の結合部４４側の外壁５０の一部と共有する形で一体成形されて設けられている。そして、結合部４４の空洞部１７を形成する壁部５１ａの内面の幅方向（図７における上下方向）の中央で且つ取付板４５が挿入される方向の中央部には、高さが取付板４５の厚みよりも若干低い円筒状の凸部４６ａが設けられ、壁部５１ａと対向する壁部５１ｂの内面には凸部４６ｂが、壁部５１ａに対する凸部４６ａの位置関係と同じ位置関係、すなわち凸部４６ａに真正面に対向するように設けられている。   More specifically, in FIG. 7 and FIG. 8, the coupling portion 44 having a hollow portion having a square cross section is formed on the outer wall 50 of the resin storage portion 43, and the wall portion 51 a on the storage portion 43 side is connected to the connection portion 44 of the storage portion 43. It is integrally formed so as to be shared with a part of the outer wall 50 on the side. The height of the attachment plate 45 is the center in the width direction (vertical direction in FIG. 7) of the inner surface of the wall portion 51a forming the cavity portion 17 of the coupling portion 44 and the center portion in the direction in which the attachment plate 45 is inserted. A cylindrical convex portion 46a slightly lower than the thickness of 45 is provided, and the convex portion 46b on the inner surface of the wall portion 51b facing the wall portion 51a has the same positional relationship as the positional relationship of the convex portion 46a with respect to the wall portion 51a, That is, it is provided so as to face the convex portion 46a directly in front.

取付板４５に設けられた突出し部４７ａは、取付板４５のその幅方向（図７における上下方向）の両端に、取付板４５の幅方向の端部を取付板４５の一方の面に向かって略直角に折り曲げ、空洞部５７への挿入方向に対して略平行になるように、挿入方向における一方の端面から他方の端面に亘って設けられ、更に取付板４５の幅方向の両端と中心との略中間付近にも、この取付板４５を屈曲させて突出し部４７ａと同じ面側に突出すように形成した突出し部４７ｂが、取付板４５の挿入方向の一方の端面から他方の端面に亘って空洞部５７への挿入方向に対して略平行になるように設けられている。この突出し部４７ｂを設けることによって、取付板４５と車体との接触面積は若干小さくなるものの、突出し部４７ａのみの場合に比べて取付板４５の剛性を更に高くすることが出来る。   The protruding portions 47 a provided on the mounting plate 45 are at both ends in the width direction (vertical direction in FIG. 7) of the mounting plate 45, and end portions in the width direction of the mounting plate 45 are directed toward one surface of the mounting plate 45.

Are provided so as to be substantially parallel to the direction of insertion into the cavity 57. By providing the protruding portion 47b, the contact area between the mounting plate 45 and the vehicle body is slightly reduced, but the rigidity of the mounting plate 45 can be further increased as compared with the case of only the protruding portion 47a.

そして取付板４５の空洞部５７へ挿入される部分の挿入方向の略中央部で、幅方向の中央部分には、円形で、その直径が壁部５１ａ，５１ｂに設けられた凸部４６ａ，４６ｂを嵌入出来るように凸部４６ａ，４６ｂよりも直径が若干大きく、凸部４６ａ，４６ｂの高さよりも深い円形の凹部４８が設けられている。また、取付板４５の突出し部４７ａ，４７ｂを設けた面の反対側の面の、取付板４５を結合部４４へ挿入するときの先端部分の角を切り落として傾斜部５９としている。   And the convex part 46a, 46b provided in the substantially central part of the insertion direction of the part inserted in the cavity part 57 of the attachment plate 45, and circular in the center part of the width direction, and the diameter was provided in wall part 51a, 51b.

そして収納部４３が取付板４５の車体側の面と同じ面に位置するように電子部品４１を取り付ける場合には、実施の形態１と同様に取付板４５の突出し部４７ａ，４７ｂの突出し方向を収納部４３の反対側となるように、取付板４５を結合部４４の空洞部５７に挿入し結合すればよい。   And when attaching the electronic component 41 so that the accommodating part 43 is located in the same surface as the surface of the attachment plate 45 on the vehicle body, the projection direction of the projections 47a and 47b of the attachment plate 45 is set as in the first embodiment. The attachment plate 45 may be inserted into the hollow portion 57 of the coupling portion 44 and coupled so as to be opposite to the storage portion 43.

このように本実施の形態によれば、取付板４５に突出し部４７ａ，４７ｂを設けることにより、重量や形状を著しく大きくすることなく取付板４５の剛性をより高くすることが出来るので、大型化した大重量の電子部品４１でも取り付けの信頼性を確保することが可能となる。そしてこのような取付板４５の一方の面に突出し部４７ａ，４７ｂを設けても、結合部４４の空洞部５７を断面方形とし、対向する壁部５１ａ，５１ｂの内面に夫々凸部４６ａ，４６ｂを設けることによって、異なる形状の取付板を新たに設計、製作することなく、電子部品４１の収納部４３の取り付け方向を取付板４５が平板の場合と同じように、一つの形状の取付板４５で二通りの取り付け方向に対応できる。   As described above, according to the present embodiment, the protrusions 47a and 47b are provided on the mounting plate 45, so that the rigidity of the mounting plate 45 can be further increased without significantly increasing the weight and shape. Even in the case of the heavy electronic component 41, the mounting reliability can be ensured. Even if projecting portions 47a and 47b are provided on one surface of the mounting plate 45, the cavity portion 57 of the coupling portion 44 is rectangular in cross section, and convex portions 46a and 46b are formed on the inner surfaces of the opposing wall portions 51a and 51b, respectively. By providing the mounting plate 45 in one shape, the mounting direction of the storage portion 43 of the electronic component 41 is set in the same direction as in the case where the mounting plate 45 is a flat plate without newly designing and manufacturing a mounting plate having a different shape.
