本考案は樹脂突起と取付板との溶着構造に関し、特に、スラスト、ラジアル方 向のガタを無くして樹脂突起と取付板とを強固に結合させた樹脂突起と取付板と の溶着構造に関する。 The present invention relates to a welding structure of a resin protrusion and a mounting plate, and more particularly to a welding structure of a resin protrusion and a mounting plate in which the resin protrusion and the mounting plate are firmly connected to each other by eliminating play in the thrust and radial directions.

従来、自動車に用いられるコンビネーションメータのような車載機器や、ＣＤ やラジオ付のカセットテープレコーダのような音響機器では、三次元形状のデザ インが重要な商品価値を備えており、このデザインを忠実に表現するために、そ の筐体には成形性の良いプラスチック等の樹脂が使用されている。そして、この 樹脂製の筐体の中に、機器の性能を満足させるための機構部品や電子回路がその 基板と共に内蔵されている。 Conventionally, in in-vehicle equipment such as combination meters used in automobiles and audio equipment such as cassette tape recorders with CDs and radios, the three-dimensional design has important commercial value, and this design is faithful. For this reason, a resin such as plastic having good moldability is used for the housing. Then, in this resin case, mechanical parts and electronic circuits for satisfying the performance of the device are built in together with the board.
【０００３】 このような樹脂製の筐体の中に機構部品や電子回路を搭載した基板等の部材を 取り付ける場合には、その取付部材の取り外しを考慮して、図４にその一例を示 すように、樹脂製の筐体にボスと呼ばれる柱状の突起４１を突設し、その先端部 にねじ穴４２を設けてねじ等の螺着部材４３を機構部品や基板等の取付部材４４ に設けられた挿通孔４５に挿通し、ねじ止めを行うのが一般的であった。When a member such as a board on which a mechanical component or an electronic circuit is mounted is mounted in such a resin casing, an example thereof is shown in FIG. 4 in consideration of removal of the mounting member. As described above, a columnar protrusion 41 called a boss is provided on a resin casing, and a screw hole 42 is provided at the tip of the protrusion to provide a screwing member 43 such as a screw on a mounting member 44 such as a mechanical component or a board. It was common to insert it through the insertion hole 45 and screw it.
【０００４】 一方、一旦取り付けた後には外す必要のないような取付部材に対しては、図５ (a) に示すように、前述のボス４１の先端部をそのまま、あるいはボス４１の先 端部に更に突起５１を設け、これらを機構部品や基板等の取付部材４４に設けら れた挿通孔４５に挿通し、図５(b) に示すように、挿通孔４５から突出する樹脂 の突起部分５１に熱を加えて溶融させ、図５(c) に示すように、樹脂の溶融変形 部５２を作る。そして、この樹脂の溶融変形部５２が挿通孔４５より大きくなる ように変形させて部材を樹脂の先端部に固定することが行われている。On the other hand, for a mounting member that does not need to be removed after once mounted, as shown in FIG. 5 (a), the tip of the boss 41 may be left as it is, or the tip of the boss 41 may be left untouched. Further, protrusions 51 are provided on the base plate, and these are inserted into the insertion holes 45 formed in the mounting member 44 such as a mechanical component or a board, and as shown in FIG. Heat is applied to 51 to melt it, and as shown in FIG. 5 (c), a resin melt-deformed portion 52 is formed. Then, the molten and deformed portion 52 of the resin is deformed so as to be larger than the insertion hole 45, and the member is fixed to the tip portion of the resin.
【０００５】 図６は従来の樹脂突起と取付板との溶着構造を更に詳しく説明するものであり 、(a) は樹脂板、または鉄板、非鉄板等の取付部材６１を、樹脂で形成された筐 体に突設されたボス６２に取り付ける場合を示すものである。取付部材６１に設 けられた挿入孔６３に、筐体に突設されたボス６２が挿通された状態を断面で示 すと、図６(b) のような状態となる。この状態でボス６２の先端部に熱を加えて 変形させ、図６(c) に示すように挿通孔６３の直径よりも大きな変形部６２Ａを 形成する。このようにすれば、取付部材６１は４つのボス６２によって筐体内に 固定されることになる。FIG. 6 is a more detailed description of a conventional welding structure of a resin protrusion and a mounting plate. FIG. 6A shows a resin plate, or a mounting member 61 such as an iron plate or a non-ferrous plate, which is formed of resin. It shows a case where it is attached to a boss 62 protruding from the casing. FIG. 6B is a sectional view showing a state in which the boss 62 protruding from the housing is inserted into the insertion hole 63 provided in the mounting member 61. In this state, heat is applied to the tip of the boss 62 to deform it, thereby forming a deformed portion 62A larger than the diameter of the insertion hole 63, as shown in FIG. 6 (c). By doing so, the mounting member 61 is fixed in the housing by the four bosses 62.
【０００６】[0006]
しかしながら、このような従来の樹脂突起と取付板との溶着構造においては、 ボス６２の直径が取付部材６１に設けられた挿入孔６３の直径より小さいために 、ボス６２と挿入孔６３との間には符号Ｂで示すようなラジアルガタが生じたり 、また、溶着不完全により変形部６２Ａと取付部材６１との間に符号Ｃで示すよ うなスラストガタが生じてしまい、取付部材６１がボス６２にしっかりと固定さ れず、振動により取付部材６１が振動するので、不快な音がする、取付部材６１ 上の部品が劣化する等の問題点がある。 However, in such a conventional welding structure of the resin protrusion and the mounting plate, since the diameter of the boss 62 is smaller than the diameter of the insertion hole 63 provided in the mounting member 61, the space between the boss 62 and the insertion hole 63 is reduced. May have radial rattling, or incomplete welding may cause thrust rattling as indicated by symbol C between the deformed portion 62A and the mounting member 61, so that the mounting member 61 is firmly attached to the boss 62. Since the mounting member 61 is not fixed and vibrates, the mounting member 61 vibrates, which causes problems such as an unpleasant sound and deterioration of parts on the mounting member 61.
【０００７】 この対策として、図６(c) に符号Ｄで示すように、変形部６２Ａと取付部材６ １との間にゴム系接着剤を塗布したり、溶着箇所を増やしたりすることが行われ ているが、コストアップが避けられないという問題が新たに発生する。As a countermeasure against this, as shown by a symbol D in FIG. 6C, a rubber adhesive may be applied between the deforming portion 62A and the mounting member 61 or the number of welding points may be increased. However, there is a new problem that cost increases cannot be avoided.
【０００８】 そこで、本考案は、樹脂突起と取付板との溶着構造において、溶着後のボスの 変形部と取付部材との間にガタを発生させないようにすることができる樹脂突起 と取付板との溶着構造を提供することを目的とする。Therefore, in the present invention, in the welding structure of the resin protrusion and the mounting plate, the resin protrusion and the mounting plate can prevent play between the deformed portion of the boss and the mounting member after welding. It is intended to provide a welded structure of

前記目的を達成する本考案の樹脂突起と取付板との溶着構造は、取付板に設け られた孔に樹脂突起を挿通し、取付板から突出する樹脂突起の先端部分を熱によ って溶融変形させ、この溶融変形部が前記挿通孔より大きくなるように変形させ て前記樹脂突起を取付板に係合する樹脂突起と取付板との溶着構造において、前 記取付板に設けられた挿通孔の周縁部近傍に複数個の係合凹部または係合凸部を 設け、樹脂の溶融変形部がこの複数個の係合凹部または係合凸部を覆うように変 形させて前記樹脂突起を取付板に係合することを特徴としている。 In the welding structure of the resin protrusion and the mounting plate of the present invention which achieves the above-mentioned object, the resin protrusion is inserted into the hole provided in the mounting plate, and the tip portion of the resin protrusion protruding from the mounting plate is melted by heat. In the welding structure of the resin projection and the mounting plate, which is deformed and deformed so that the melted and deformed portion is larger than the insertion hole, the resin projection is engaged with the mounting plate. A plurality of engaging concave portions or engaging convex portions are provided in the vicinity of the peripheral portion of the resin, and the resin melting deformation portion is deformed so as to cover the plural engaging concave portions or engaging convex portions, and the resin protrusion is attached. It is characterized by engaging a plate.

本考案の樹脂突起と取付板との溶着構造によれば、取付板に設けられた孔に樹 脂突起を挿通し、取付板から突出する樹脂突起の先端部分を熱によって溶融変形 させ、この溶融変形部が挿通孔より大きくなるように変形させると、取付板の挿 通孔の周縁部近傍に複数個の凹部が設けられた場合は、この凹部に樹脂の溶融変 形部が入り込むので溶融変形部と凹部とが係合し、取付板の挿通孔の周縁部近傍 に複数個の凸部が設けられた場合は、この凸部が樹脂の溶融変形部に食い込むの で溶融変形部と凸部とが係合する。この結果、溶融変形部と取付板とがガタなく 係合される。 According to the welding structure of the resin protrusion and the mounting plate of the present invention, the resin protrusion is inserted into the hole provided in the mounting plate, the tip portion of the resin protrusion protruding from the mounting plate is melted and deformed by heat, and this melting is performed. If the deformed part is deformed so that it is larger than the insertion hole, and if multiple recesses are provided near the peripheral edge of the insertion hole of the mounting plate, the melted deformed part of the resin will enter these recesses, causing melt deformation. If a plurality of protrusions are provided in the vicinity of the peripheral edge of the insertion hole of the mounting plate, the protrusions bite into the resin melt-deformation part, so the melt-deformation part and the protrusion And are engaged. As a result, the melted deformable portion and the mounting plate are engaged with each other without backlash.
【００１１】[0011]
以下添付図面を用いて本考案の実施例を詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
【００１２】 図１は本考案の樹脂突起と取付板との溶着構造の一実施例の構成を示す斜視図 である。図１において、１は樹脂製の筐体１０に突設されたボスと呼ばれる柱状 の突起（以後ボスという）、２はこのボス１に取り付ける機構部品や基板等の取 付部材、３は取付部材２に設けられたボス１の挿通孔である。FIG. 1 is a perspective view showing a structure of an embodiment of a welding structure of a resin protrusion and a mounting plate according to the present invention. In FIG. 1, reference numeral 1 denotes a columnar protrusion called a boss (hereinafter referred to as a boss) protruding from a resin casing 10, 2 is a mounting member such as a mechanical component or a board mounted on the boss 1, and 3 is a mounting member. 2 is an insertion hole of the boss 1 provided on the second boss 2.
【００１３】 この実施例では、取付部材２に設けられたボス１の挿通孔３の周縁部に、挿通 孔３の同心円状に所定の深さを持った係合凹部４を複数個設けている。この係合 凹部４は、この実施例では均一な深さを備えた円形の浅い溝であるが、深さは特 に一定でなくてもよく、また、形状も円形に限定されるものではない。更に、こ の係合凹部４はこの実施例では等間隔に挿通孔３の周縁部に同心円状に設けてい るが、等間隔である必要は特になく、また、同心円状である必要もない。この係 合凹部４は、挿通孔３にボス１を挿通した後に熱で溶融変形させた時に、その溶 融変形部で覆われる部位の取付部材１上にあれば良いものである。In this embodiment, a plurality of engaging recesses 4 having a predetermined depth are provided concentrically in the insertion hole 3 at the peripheral portion of the insertion hole 3 of the boss 1 provided in the mounting member 2. . The engaging recess 4 is a circular shallow groove having a uniform depth in this embodiment, but the depth does not have to be particularly constant, and the shape is not limited to the circular shape. . Further, although the engaging recesses 4 are concentrically provided in the peripheral portion of the insertion hole 3 at equal intervals in this embodiment, they need not be evenly spaced, and need not be concentric. It is sufficient that the engaging recess 4 is provided on the mounting member 1 at a portion covered by the melt-deformed portion when the boss 1 is inserted into the insertion hole 3 and then melted and deformed by heat.
【００１４】 図２(a) は図１に示した筐体１０に突設したボス１を、取付部材２の挿通孔３ に挿通した状態を示す断面図である。ボス１の高さは取付部材２の厚さよりも大 きいので、挿通孔３に挿通されたボス１は挿通孔３の上方に突出する。この状態 で、従来と同様にボス１の先端部に半田ごて等によって熱を加えて先端部を変形 させ、図２(b) に示すように挿通孔３の直径よりも大きな溶融変形部１Ａを形成 する。このとき、溶融変形部１Ａの一部が取付部材２の挿通孔２の周縁部に設け た係合凹部４の中に侵入する。FIG. 2A is a sectional view showing a state in which the boss 1 projecting from the housing 10 shown in FIG. 1 is inserted into the insertion hole 3 of the mounting member 2. Since the height of the boss 1 is larger than the thickness of the mounting member 2, the boss 1 inserted into the insertion hole 3 projects above the insertion hole 3. In this state, heat is applied to the tip of the boss 1 by a soldering iron or the like to deform the tip, as shown in FIG. 2 (b). As shown in FIG. To form. At this time, a part of the melted and deformed portion 1A penetrates into the engaging recessed portion 4 provided in the peripheral portion of the insertion hole 2 of the mounting member 2.
【００１５】 このとき、溶融変形部１Ａの一部が係合凹部４を完全に埋めるように係合凹部 ４内に侵入するのが最も良いが、溶融変形部１Ａが係合凹部４を完全に埋めるよ うに係合凹部４内に侵入しないこともある。ところが、図１に示したように、係 合凹部４は取付部材２の挿通孔３の周縁部に複数子設けられているので、例え、 溶融変形部１Ａがこの係合凹部４に完全に侵入しなくても、前述のラジアルガタ が生じたり、スラストガタが生じることがなく、取付部材２がボス１にしっかり と固定されることになる。この結果、取付部材２に振動がなくなり不快な音がし なくなったり、取付部材２上の部品が劣化する等の問題点が生じない。よって、 溶融変形部１Ａと取付部材２との間にゴム系接着剤を塗布したり、溶着箇所を増 やしたりする必要がなく、コストアップの恐れがない。At this time, it is best that a part of the melt-deformed portion 1A penetrates into the engagement recess 4 so as to completely fill the engagement recess 4, but the melt-deformed portion 1A completely fills the engagement recess 4. It may not penetrate into the engagement recess 4 so as to fill it. However, as shown in FIG. 1, since the plurality of engaging recesses 4 are provided in the peripheral portion of the insertion hole 3 of the mounting member 2, for example, the melting deformation portion 1A completely penetrates into the engaging recess 4. Even without doing so, the above-described radial rattling and thrust rattling do not occur, and the mounting member 2 is firmly fixed to the boss 1. As a result, there is no problem that the mounting member 2 does not vibrate, no unpleasant sound is produced, and the parts on the mounting member 2 are deteriorated. Therefore, there is no need to apply a rubber-based adhesive between the melt-deformed portion 1A and the mounting member 2 or increase the number of welded portions, and there is no risk of cost increase.
【００１６】 図３(a) ，(b) は本考案における取付部材２の挿通孔３の周縁部に設ける係合 凹部の別の実施例を示すものであり、図２(a) と同じ部位の取付部材２のみの形 状を示している。図２(a) の実施例では、係合凹部４は均一な深さを備えた円形 の浅い溝であったが、図３(a) の実施例における係合凹部５は円錐形の溝であり 、図３(b) の実施例における係合凹部６は、半球状の溝である。このように、係 合凹部の溝の形状は種々考えられる。FIGS. 3 (a) and 3 (b) show another embodiment of the engaging recess provided in the peripheral portion of the insertion hole 3 of the mounting member 2 according to the present invention, which is the same as FIG. 2 (a). The shape of only the mounting member 2 is shown. In the embodiment of FIG. 2 (a), the engaging recess 4 is a circular shallow groove having a uniform depth, but the engaging recess 5 in the embodiment of FIG. 3 (a) is a conical groove. The engagement recess 6 in the embodiment of FIG. 3 (b) is a hemispherical groove. As described above, various shapes of the groove of the engaging recess can be considered.
【００１７】 これまで説明した実施例では、取付部材２の挿通孔３の周縁部に、溶融変形部 １Ａの一部を侵入させることにより、溶融変形部１Ａと取付部材２との間にラジ アルガタやスラストガタを生じさせないための係合凹部４〜６が設けられていた 。しかしながら、溶融変形部１Ａと取付部材２との間にラジアルガタやスラスト ガタを生じさせないためには、取付部材２側に係合凸部を設けてこれを溶融変形 部１Ａ内に食い込ませるようにしても同様の効果が得られる。そこで、図３(c) から(e) には取付部材２の挿通孔３の周縁部に、係合凹部の代わりに係合凸部を 設けた実施例を示している。図３(c) から(e) も図２(a) と同じ部位の取付部材 ２のみの形状を示している。In the embodiments described so far, a part of the melt-deformed portion 1A is caused to enter the peripheral portion of the insertion hole 3 of the attachment member 2 so that the radial deformation between the melt-deformed portion 1A and the attachment member 2 is reduced. The engaging recesses 4 to 6 were provided to prevent the occurrence of thrust play and thrust play. However, in order to prevent radial rattling or thrust rattling between the melt-deformed portion 1A and the mounting member 2, an engaging convex portion is provided on the mounting member 2 side so that the engaging convex portion is bitten into the melt-deformed portion 1A. Also has the same effect. Therefore, FIGS. 3 (c) to 3 (e) show an embodiment in which an engaging convex portion is provided instead of the engaging concave portion at the peripheral portion of the insertion hole 3 of the mounting member 2. 3 (c) to 3 (e) also show the shape of only the mounting member 2 in the same portion as in FIG. 2 (a).
【００１８】 図３(c) の実施例では、係合凸部７は円柱状の小さなボスの形状をしており、 図３(d) の実施例では、係合凸部８は円錐形の突起であり、図３(e) の実施例に おける係合突起９は、半球状の突起である。このように、係合凸部の形状は種々 考えられる。In the embodiment of FIG. 3 (c), the engagement protrusion 7 has the shape of a cylindrical small boss, and in the embodiment of FIG. 3 (d), the engagement protrusion 8 has a conical shape. The engaging projection 9 in the embodiment of FIG. 3 (e) is a hemispherical projection. As described above, various shapes of the engaging protrusion can be considered.

以上説明したように、本考案によれば、樹脂突起と取付板との溶着構造におい て、溶着後のボスの変形部と取付部材との間にスラストガタやラジアルガタを発 生させないようにすることができ、信頼性が向上するという効果がある。 As described above, according to the present invention, in the welding structure of the resin protrusion and the mounting plate, it is possible to prevent the generation of thrust rattling or radial rattling between the deformed portion of the boss and the mounting member after welding. This has the effect of improving reliability.
