Abstract

<P>PROBLEM TO BE SOLVED: To prevent fitting burrs from spattering from an engagement hole to the outside even if fitting burrs occur when engagement projected parts are engaged with engagement holes in engagement pieces. <P>SOLUTION: A bridge part 23 is formed on the outer surface 19b of the first engagement piece 19 having the first engagement hole 18 so as to cross the first engagement hole 18. Since the first engagement projected part 25 interferes with the engagement piece 19 when the first engagement projected part 25 of an insulator 13 is engaged with the engagement hole 18 in a switch body 12, the inner surface 19a of the engagement piece 19 is cut off by the engagement projected part 25 to generate, a so-called, the fitting burrs. Even if the fitting burrs occur, the fitting burrs can be prevented from spattering from the engagement hole 18 to the outside since they are collided with the bridge part 23 installed so as to cross the engagement hole 18. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、いわゆるスナップフィット構造により係合孔と係合凸部とを係合させる構成の係合構造に関する。   The present invention relates to an engagement structure configured to engage an engagement hole and an engagement convex portion by a so-called snap-fit structure.

従来、例えばスイッチ装置において、スイッチボディと、固定接点が設けられたインシュレータとを組み付ける場合、いわゆるスナップフィット構造により係合させる構造が採用されている。
図７及び図８には、その係合構造の一例が示されている。なお、図７はスイッチボディとインシュレータを組み付ける前の状態を示したもので、（ａ）は一部を破断して示す破断側面図、（ｂ）は（ａ）の矢印Ｘ１方向から見た矢視図である。また、図８は、スイッチボディとインシュレータを組み付けた状態での破断側面図である。 Conventionally, for example, in a switch device, when a switch body and an insulator provided with a fixed contact are assembled, a structure that is engaged by a so-called snap-fit structure is employed.
7 and 8 show an example of the engagement structure. FIG. 7 shows a state before the switch body and the insulator are assembled. (A) is a cutaway side view showing a part thereof broken, and (b) is an arrow viewed from the direction of arrow X1 in (a). FIG. FIG. 8 is a cutaway side view of the switch body and the insulator assembled together.

図７において、スイッチボディ１は、合成樹脂例えばＡＢＳ樹脂により形成されたもので、収容部２を有していて、この収容部２の周囲に、両面が開口した係合孔３を有する係合片４が一体成形により設けられている。その係合片４の内面４ａの先端部側には、挿入ガイド用の斜面を有するガイド溝部５が形成されている。これに対して、インシュレータ６は、合成樹脂、例えばＡＢＳ樹脂よりも硬いＰＢＴ（ポリブチレンテレフタレート）樹脂により形成されたもので、外面に、上記係合孔３に係脱可能に係合する係合凸部７が一体成形により設けられている。
ここで、スイッチボディ１とインシュレータ６を組み付ける場合、スイッチボディ１に対してインシュレータ６を相対的に近づけ（矢印Ａ１参照）、係合凸部７を、ガイド溝部５に挿入させながら、インシュレータ６をスイッチボディ１の収容部２に嵌合させる。このとき、係合凸部７が、係合片４を弾性変形させながら当該係合片４の内面を摺動して係合孔３に係合する（図８参照）。 In FIG. 7, the switch body 1 is formed of a synthetic resin, for example, ABS resin, has a housing portion 2, and has an engagement hole 3 with both surfaces opened around the housing portion 2. The piece 4 is provided by integral molding. On the distal end side of the inner surface 4a of the engagement piece 4, a guide groove portion 5 having a slope for insertion guide is formed. On the other hand, the insulator 6 is formed of a synthetic resin, such as PBT (polybutylene terephthalate) resin harder than ABS resin, and is engaged with the outer surface so as to be detachably engaged with the engagement hole 3. The convex part 7 is provided by integral molding.
Here, when the switch body 1 and the insulator 6 are assembled, the insulator 6 is moved closer to the switch body 1 (see arrow A1), and the engaging protrusion 7 is inserted into the guide groove 5 while the insulator 6 is inserted. The switch body 1 is fitted into the accommodating portion 2. At this time, the engaging projection 7 slides on the inner surface of the engaging piece 4 while elastically deforming the engaging piece 4 and engages with the engaging hole 3 (see FIG. 8).

上記したスイッチボディ１とインシュレータ６を組み付ける場合に、係合凸部７が係合片４と干渉するため、係合凸部７により係合片４の内面が削られて、いわゆる嵌合ばり８（二点鎖線で示す）（樹脂の削りくずのようなもの）が発生し、この嵌合ばり８が係合孔４を通って外部に飛散することがある。すると、この嵌合ばり８が作業台上に落ち、その嵌合ばり８が他の部品に付着して、スイッチ装置のスイッチ機構の内部に侵入し、これがスイッチ機構の接触不良などの原因になることがある。   When the switch body 1 and the insulator 6 described above are assembled, the engaging convex portion 7 interferes with the engaging piece 4. (Indicated by a two-dot chain line) (such as resin shavings) may occur, and this fitting beam 8 may be scattered outside through the engaging hole 4. Then, the fitting beam 8 falls on the work table, and the fitting beam 8 adheres to other parts and enters the inside of the switch mechanism of the switch device, which causes a contact failure of the switch mechanism. Sometimes.

本発明は上記した事情に鑑みてなされたものであり、その目的は、係合凸部を係合片の係合孔に係合させる際に嵌合ばりが発生したとしても、その嵌合ばりが係合孔から外部へ飛散することを防止できる係合構造を提供するにある。   The present invention has been made in view of the above circumstances, and the object thereof is to provide a fitting beam even when a fitting beam is generated when the engaging protrusion is engaged with the engaging hole of the engaging piece. It is an object of the present invention to provide an engagement structure that can prevent splashing from the engagement hole to the outside.

上記の目的を達成するために、本発明は、係合孔を有する係合片と、前記係合孔に係脱可能に係合する係合凸部とを備え、前記係合凸部を前記係合片の一面に沿って相対的に摺動させることにより、前記係合凸部を前記係合孔に係合させる構成の係合構造において、前記係合片にあって前記一面とは反対側の面に、前記係合孔を横切るように架橋部を設けたことを特徴とする。   In order to achieve the above object, the present invention includes an engagement piece having an engagement hole, and an engagement projection that is detachably engaged with the engagement hole. In the engagement structure configured to engage the engagement protrusion with the engagement hole by relatively sliding along one surface of the engagement piece, the engagement piece is opposite to the one surface. A bridging portion is provided on the side surface so as to cross the engagement hole.

本発明によれば、係合凸部を係合片の係合孔に係合させる際に嵌合ばりが発生したとしても、その嵌合ばりが、係合孔を横切るように設けられた架橋部に当たることにより、係合孔から外部へ飛散することが防止される。   According to the present invention, even when a fitting beam is generated when the engaging projection is engaged with the engaging hole of the engaging piece, the bridging provided so that the fitting beam crosses the engaging hole. By hitting the part, scattering from the engagement hole to the outside is prevented.

以下、本発明の一実施例について図１ないし図６を参照して説明する。
まず、図４及び図５には、自動車のパワーウインドウにおけるウインドレギュレータ用のスイッチ装置１１が示されている。このスイッチ装置１１は、スイッチボディ１２と、このスイッチボディ１２の下部に組みつけられたインシュレータ１３と、スイッチボディ１２の上部に軸１４を介して揺動可能に取り付けられた操作ノブ１５と、スイッチボディ１２の内部に配設されたスイッチ機構１６（図５参照）とから構成されている。
このうち、スイッチボディ１２は、合成樹脂例えばＡＢＳ樹脂により形成されたもので、これの下部には、図３に示すように、下面側が開口した矩形枠状の収容部１７が形成されている。この収容部１７の周壁部のうち前部（図３及び図５で左側）に、内外両面が開口した第１の係合孔１８（本発明の係合孔に相当）を有する第１の係合片１９（本発明の係合片に相当）が設けられ、また、後部の左右両側に、内外両面が開口した第２の係合孔２０を有する第２の係合片２１（図３及び図４に一方のみ示す）が設けられている。 Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
4 and 5 show a switch device 11 for a window regulator in a power window of an automobile. The switch device 11 includes a switch body 12, an insulator 13 assembled to the lower portion of the switch body 12, an operation knob 15 attached to the upper portion of the switch body 12 via a shaft 14, and a switch. The switch mechanism 16 (refer FIG. 5) arrange | positioned inside the body 12 is comprised.
Among these, the switch body 12 is formed of a synthetic resin, for example, an ABS resin, and a rectangular frame containing portion 17 whose lower surface side is opened is formed at a lower portion thereof as shown in FIG. A first engagement member having a first engagement hole 18 (corresponding to the engagement hole of the present invention) having both inner and outer surfaces opened in the front portion (left side in FIGS. 3 and 5) of the peripheral wall portion of the housing portion 17. A combination piece 19 (corresponding to the engagement piece of the present invention) is provided, and a second engagement piece 21 having second engagement holes 20 having both inner and outer sides opened on both the left and right sides of the rear portion (see FIGS. 3 and 3). Only one of them is shown in FIG.

そして、図１及び図２にも示すように、第１の係合片１９の一面である内面１９ａ側の先端部には、斜面を有するガイド溝部２２が形成され、また、その一面とは反対側の面である外面１９ｂに、第１の係合孔１８を上下方向（図１及び図２では左右方向）に横切るように、突条部からなる架橋部２３が一体に設けられている。また、第２の係合片２１の内面側の先端部にも、図示はしないがガイド溝部が形成されている。なお、第２の係合片２１の外面には、上記架橋部２３のような架橋部は設けられてはいない。   As shown in FIGS. 1 and 2, a guide groove portion 22 having a slope is formed at the front end portion on the inner surface 19a side which is one surface of the first engagement piece 19, and is opposite to the one surface. On the outer surface 19b, which is a side surface, a bridging portion 23 made of a ridge portion is integrally provided so as to cross the first engagement hole 18 in the vertical direction (left and right direction in FIGS. 1 and 2). Further, a guide groove portion (not shown) is also formed at the tip portion on the inner surface side of the second engagement piece 21. Note that a bridging portion such as the bridging portion 23 is not provided on the outer surface of the second engagement piece 21.

上記インシュレータ１３は、合成樹脂例えばＰＢＴ樹脂により形成されたもので、これの外周部のうち前部１３ａ（図３及び図５で左側）に、上記第１の係合孔１８に係脱可能に係合する第１の係合凸部２５（本発明の係合凸部に相当）が設けられ、また、左右両側部に、上記第２の係合孔２０に係脱可能に係合する第２の係合凸部２６（図３及び図４に一方のみ示す）が設けられている。また、インシュレータ１３の固定接点配置部２７の上面側に複数の固定接点２８が設けられ、下部のコネクタ部２９に複数の接続ターミナル３０が設けられている。   The insulator 13 is formed of a synthetic resin such as PBT resin, and can be engaged with and disengaged from the first engagement hole 18 at the front portion 13a (left side in FIGS. 3 and 5) of the outer peripheral portion thereof. A first engagement convex portion 25 (corresponding to the engagement convex portion of the present invention) to be engaged is provided, and a first engagement convex portion 25 detachably engaged with the second engagement hole 20 is provided on both left and right side portions. Two engaging projections 26 (only one is shown in FIGS. 3 and 4) are provided. A plurality of fixed contacts 28 are provided on the upper surface side of the fixed contact arrangement portion 27 of the insulator 13, and a plurality of connection terminals 30 are provided on the lower connector portion 29.

ここで、上記スイッチボディ１２とインシュレータ１３との組み付けは、次のようにして行われる。すなわち、図１及び図３に示すように、スイッチボディ１２における収容部１７の開口部に、インシュレータ１３の上部を相対的に近づけて挿入（図１の矢印Ａ２参照）し、第１の係合凸部２５を第１の係合片１９のガイド溝部２２に挿入すると共に、第２の係合凸部２６を対応する第２の係合片２１のガイド溝部に挿入しながら、スイッチボディ１２の収容部１７にインシュレータ１３の上部を嵌合させる。これに伴い、第１の係合凸部２５が、第１の係合片１９の内面１９ａを摺動して当該第１の係合片１９を弾性変形させながら第１の係合孔１８に係合する（図２参照）と共に、第２の係合凸部２６が対応する第２の係合片２１の内面を摺動して当該第２の係合片２１を弾性変形させながら第２の係合孔２０に係合する。これにより、図４及び図５に示すように、インシュレータ１３がスイッチボディ１２に組み付けられる。   Here, the assembly of the switch body 12 and the insulator 13 is performed as follows. That is, as shown in FIGS. 1 and 3, the upper portion of the insulator 13 is inserted relatively close to the opening of the accommodating portion 17 in the switch body 12 (see arrow A2 in FIG. 1), and the first engagement is performed. While inserting the convex portion 25 into the guide groove portion 22 of the first engagement piece 19 and inserting the second engagement convex portion 26 into the guide groove portion of the corresponding second engagement piece 21, the switch body 12 The upper portion of the insulator 13 is fitted into the housing portion 17. Accordingly, the first engagement convex portion 25 slides on the inner surface 19a of the first engagement piece 19 and elastically deforms the first engagement piece 19 into the first engagement hole 18. The second engaging projection 26 slides on the inner surface of the corresponding second engaging piece 21 and elastically deforms the second engaging piece 21 while engaging (see FIG. 2). The engagement hole 20 is engaged. As a result, the insulator 13 is assembled to the switch body 12 as shown in FIGS.

上記インシュレータ１３の固定接点配置部２７の上面側に、スイッチ機構１６が設けられている。このスイッチ機構１６は２組が並列に設けられているが、図５には１組のみ示されており、主に１組のスイッチ機構１６について説明する。固定接点配置部２７の上面側には、固定接点２８に対して接離する可動接触子３５が揺動可能に設けられていて、この可動接触子３５と固定接点２８とによりスイッチ機構１６を構成している。上記操作ノブ１５の下部には、各可動接触子３５に対応して、下面が開口した筒部３６が突設されていて、この筒部３６が、スイッチボディ１２の収容部１７内まで挿入されている。その筒部３６には、プッシャ３７及びこのプッシャ３７を下方へ付勢する圧縮コイルばね３８が収容されていて、プッシャ３７の先端部が、対応する可動接触子３５の上面に当接している。   A switch mechanism 16 is provided on the upper surface side of the fixed contact arrangement portion 27 of the insulator 13. Although two sets of the switch mechanisms 16 are provided in parallel, only one set is shown in FIG. 5, and the one set of switch mechanisms 16 will be mainly described. On the upper surface side of the fixed contact arrangement portion 27, a movable contact 35 that comes in contact with and separates from the fixed contact 28 is swingably provided, and the switch mechanism 16 is configured by the movable contact 35 and the fixed contact 28. is doing. At the lower part of the operation knob 15, corresponding to each movable contact 35, a cylindrical part 36 having an open bottom surface is projected, and this cylindrical part 36 is inserted into the accommodating part 17 of the switch body 12. ing. The cylindrical portion 36 accommodates a pusher 37 and a compression coil spring 38 that urges the pusher 37 downward, and the tip of the pusher 37 is in contact with the upper surface of the corresponding movable contact 35.

上記構成において、操作ノブ１５の非操作状態では、操作ノブ１５は、図４及び図５に示す中立位置に保持されている。この状態で、操作ノブ１５を反時計回り方向へ回動させると、プッシャ３７が可動接触子３５の上面を摺動することに伴い、当該可動接触子３５が逆に傾いてスイッチが切り替わり、図示しないモータが駆動してウインドが下降する。そして、操作ノブ１５への操作力を解除すると、プッシャ３７が可動接触子３５の上面を摺動しながら凹部に復帰することに伴い操作ノブ１５が元の中立位置に戻されると共に、可動接触子３５が元の傾斜状態に戻り、ウインドの下降が停止する。
また、非操作状態の操作ノブ１５を、時計回り方向へ回動させると、隣のスイッチ機構１６の可動接触子３５が逆に傾いてスイッチが切り替わり、図示しないモータが駆動してウインドが上昇する。そして、操作ノブ１５への操作力を解除すると、操作ノブ１５が元の中立位置に戻されると共に、可動接触子３５が元の傾斜状態に戻り、ウインドの上昇が停止する。 In the above configuration, when the operation knob 15 is not operated, the operation knob 15 is held at the neutral position shown in FIGS. 4 and 5. In this state, when the operation knob 15 is rotated counterclockwise, the pusher 37 slides on the upper surface of the movable contact 35, so that the movable contact 35 is tilted in the reverse direction to switch the switch. The motor does not drive and the window descends. When the operating force on the operation knob 15 is released, the operation knob 15 is returned to the original neutral position as the pusher 37 returns to the recess while sliding on the upper surface of the movable contact 35, and the movable contact 35 returns to the original tilted state, and the descent of the window stops.
When the operation knob 15 in the non-operation state is rotated in the clockwise direction, the movable contact 35 of the adjacent switch mechanism 16 is tilted in the reverse direction to switch the switch, and a motor (not shown) is driven to raise the window. . When the operation force applied to the operation knob 15 is released, the operation knob 15 is returned to the original neutral position, the movable contact 35 is returned to the original tilted state, and the rising of the window is stopped.

上記した実施例においては、スイッチボディ１２の収容部１７にインシュレータ１３を嵌合して組み付ける場合に、第１の係合凸部２５が第１の係合片１９と干渉するため、その第１の係合凸部２５により第１の係合片１９の内面１９ａが削られて、いわゆる嵌合ばり（図示せず）が発生することがある。この場合、第１の係合片１９の外面１９ｂには、第１の係合孔１８を上下方向（図１及び図２では左右方向）に横切るように架橋部２３が設けられているため、嵌合ばりがその架橋部２３に当たることにより、係合孔１８から外部へ飛散することが防止される。このため、外部へ飛散した嵌合ばりが、他の部品のスイッチ機構などに侵入して接点不良などの原因になることを未然に防止できる。   In the above-described embodiment, when the insulator 13 is fitted and assembled to the accommodating portion 17 of the switch body 12, the first engagement convex portion 25 interferes with the first engagement piece 19. The inner protrusion 19 of the first engagement piece 19 may be scraped by the engagement protrusion 25 to generate a so-called fitting beam (not shown). In this case, the outer surface 19b of the first engagement piece 19 is provided with the bridging portion 23 so as to cross the first engagement hole 18 in the up-down direction (left-right direction in FIGS. 1 and 2). When the fitting beam hits the bridging portion 23, it is prevented from scattering from the engagement hole 18 to the outside. For this reason, it is possible to prevent the fitting beam scattered to the outside from entering the switch mechanism of another component and causing a contact failure.

ここで、嵌合ばりが外部へ飛散することを防止するために、比較例として示す図６のような構成とすることが考えられる。すなわち、スイッチボディ１２における第１の係合片４０の第１の係合穴４１を、スライド型により底部（図６で上部）が閉塞された片面開口型とする。
しかしながら、このような構成とすると、第１の係合片４０全体の厚さｔ１が大きくなるため、第１の係合片４０の剛性が高くなり、当該第１の係合片４０を弾性変形させるための荷重が著しく高くなってしまう。また、その荷重を下げるために、第１の係合片４０の厚さｔ１を小さくすると、第１の係合穴４１の深さが浅くなり、第１の係合凸部２５の掛かり代が少なくなり、抜け強度を満足できなくなってしまう不具合がある。 Here, in order to prevent the fitting beam from scattering to the outside, it is conceivable to adopt a configuration as shown in FIG. 6 as a comparative example. That is, the first engagement hole 41 of the first engagement piece 40 in the switch body 12 is a single-sided opening type in which the bottom (upper part in FIG. 6) is closed by a slide type.
However, with such a configuration, since the thickness t1 of the entire first engagement piece 40 is increased, the rigidity of the first engagement piece 40 is increased, and the first engagement piece 40 is elastically deformed. The load for making it will become remarkably high. Further, when the thickness t1 of the first engagement piece 40 is reduced in order to reduce the load, the depth of the first engagement hole 41 becomes shallow, and the engagement margin of the first engagement convex portion 25 is reduced. There is a problem that it becomes less and the pull-out strength cannot be satisfied.

この点、上記した本実施例によれば、架橋部２３を設けた分は第１の係合片１９の剛性は高くなるが、一部のみであるため、嵌合の際の荷重の増加は少なく抑えることができる。また、第１の係合孔１８は両面が開口した形状となっているため、第１の係合凸部２５との係合代を確保でき、抜け強度を満足できる。
なお、上記した実施例においては、第２の係合孔２０を有する第２の係合片２１には、架橋部は設けられていないが、その第２の係合片２１の外面にも架橋部２３を設けるようにしても良いことはもちろんである。 In this regard, according to the above-described embodiment, the rigidity of the first engagement piece 19 is increased by providing the bridging portion 23, but only a part of the rigidity is increased, so that an increase in load at the time of fitting is not increased. It can be kept low. Further, since the first engagement hole 18 has a shape in which both surfaces are opened, an engagement allowance with the first engagement convex portion 25 can be secured, and the pull-out strength can be satisfied.
In the embodiment described above, the second engaging piece 21 having the second engaging hole 20 is not provided with a bridging portion, but the outer surface of the second engaging piece 21 is also bridging. Of course, the portion 23 may be provided.

本発明は、上記した実施例にのみ限定されるものではなく、例えばスイッチ装置以外でも、２部品を係合させる構造に広く適用することができる。   The present invention is not limited only to the above-described embodiments, and can be widely applied to structures for engaging two parts other than, for example, a switch device.
