Description

本発明は、樹脂成形体に関する。 The present invention relates to a resin molded body.

従来から、金型を用いた射出成形などの手法によって成形された樹脂成形体が知られている。この種の樹脂成形体には、一般に、金型に注入された樹脂の冷却時に生じる成形収縮に起因し、窪み等（いわゆるヒケ）が生じる場合がある。成形収縮の原理上、樹脂成形体の厚みが大きいほど、大きな窪み等（ヒケ）が生じる可能性が高い。そこで、一般に、この種の樹脂成形体には薄肉化のための穴（いわゆる抜き）が設けられる（例えば、特許文献１〜３を参照。）。 BACKGROUND ART Conventionally, a resin molded body molded by a method such as injection molding using a mold has been known. In this type of resin molded body, generally, a dent or the like (so-called sink mark) may occur due to molding shrinkage that occurs when the resin injected into the mold is cooled. According to the principle of molding shrinkage, the larger the thickness of the resin molded body, the higher the possibility that large depressions (sinks) will occur. Therefore, in general, a resin molded body of this type is provided with a hole (so-called punch) for thinning (for example, refer to Patent Documents 1 to 3).

ところで、車両用の変速機やモータ等のように潤滑油などの液体が封入されている箱状体の内外を電気的に接続する中継コネクタは、箱状体に設けられた取付孔に差し込まれるように箱状体に組み付けられる。中継コネクタには、通常、潤滑油などの漏れを抑制するためのシーリング部品（パッキン等）を設けるための組付部（シール溝など）が設けられる。箱状体の取付孔を確実に封止するべく、この組付部は出来る限り寸法精度に優れることが望ましい。 By the way, a relay connector for electrically connecting the inside and the outside of a box-shaped body in which a liquid such as lubricating oil is sealed, such as a transmission for a vehicle or a motor, is inserted into a mounting hole provided in the box-shaped body. Assembled in a box-shaped body. The relay connector is usually provided with an assembly portion (seal groove or the like) for providing a sealing component (packing or the like) for suppressing leakage of lubricating oil or the like. In order to surely seal the mounting hole of the box-shaped body, it is desirable that this assembling portion has excellent dimensional accuracy.

そのため、一般に、組付部の周辺には薄肉化のための穴（抜き）が他の箇所よりも重点的に設けられる。一方、このような穴を設けることは、中継コネクタそのものの設計自由度を低減させる原因になり得る。また、中継コネクタの形状によっては、組付部（シール溝など）の周辺に穴を設けるために複雑な形状の金型を使用することとなり、中継コネクタの生産性向上の妨げとなる場合もある。このように、シーリング部品を組み付ける組付部を有する樹脂成形体において、寸法精度と生産性との両立が困難となる場合がある。 Therefore, generally, holes (drilling) for reducing the wall thickness are provided in the periphery of the assembly portion more intensively than other locations. On the other hand, the provision of such a hole may reduce the degree of freedom in designing the relay connector itself. In addition, depending on the shape of the relay connector, a die having a complicated shape may be used to provide a hole around the assembly portion (such as a seal groove), which may hinder the improvement of the productivity of the relay connector. .. As described above, in the resin molded body having the assembly portion to which the sealing component is assembled, it may be difficult to achieve both dimensional accuracy and productivity.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、シーリング部品を組み付ける組付部を有しながら寸法精度と生産性とを両立可能な樹脂成形体、を提供することにある。 The present invention has been made in view of the above-described circumstances, and an object thereof is to provide a resin molded body that has both an assembly portion for assembling a sealing component and is capable of achieving both dimensional accuracy and productivity. is there.

樹脂成形体であること。 In order to achieve the above-mentioned object, the resin molding according to the present invention is characterized by the following [1] to [3].
[1]
A resin molded body, comprising a terminal conductor extending in a predetermined direction, a primary molded body extending in the predetermined direction along the terminal conductor, and a resin-made secondary molded body covering the primary molded body,
The primary molded body,
Has an extending portion extending in a direction different from the predetermined direction,
The secondary molded body,
The outer surface has an assembling portion for assembling the sealing component while covering the extending portion,
It must be a resin molding.
[2]
In the resin molding of [1] above,
The secondary molded body,
It has a hood-shaped exposed portion that is exposed to the outside while surrounding the end portion of the terminal conductor,
The exposed portion is
Configured to extend along the extending direction of the extending portion,
It must be a resin molding.
[3]
In the resin molding according to [1] or [2] above,
At least a part of the end surface of the extended end of the extended portion of the primary molded body,
It has a shape corresponding to the shape of the outer surface of the assembly portion of the secondary molded body,
It must be a resin molding.

上記［１］の構成の樹脂成形体は、端子導体に沿って延びる一次成形体と、一次成形体を覆う二次成形体と、を備える。更に、一次成形体から端子導体の延びる方向とは異なる方向に延出部が延びており、この延出部を覆うように、二次成形体のシーリング部品（パッキン等）を組み付けるための組付部（シール溝など）が形成される。そのため、一次成形体の延出部が存在しない場合に比べ、組付部を構成する二次成形体の厚さが薄くなる。即ち、従来のように組付部の周辺に穴（抜き）を設けなくても、組付部の薄肉化を実現できる。また、延出部は端子導体に沿って延びる部分（即ち、一次成形体の本体部）から離れるように延びているため、一次成形体による端子導体の保持機能を損なうこともない。よって、組付部の寸法精度を高めながら、組付部の周辺に穴（抜き）を設ける場合に比べて樹脂成形体の生産性を向上できる。したがって、本構成の樹脂成形体は、シーリング部品を組み付ける組付部を有しながら寸法精度と生産性とを両立可能である。 The resin molded body having the above-mentioned configuration [1] includes a primary molded body extending along the terminal conductor and a secondary molded body covering the primary molded body. Further, the extending portion extends from the primary molded body in a direction different from the direction in which the terminal conductor extends, and an assembly for assembling the sealing component (packing or the like) of the secondary molded body so as to cover the extended portion. A part (a seal groove or the like) is formed. Therefore, the thickness of the secondary molded body that constitutes the assembly portion is smaller than that when the extended portion of the primary molded body does not exist. That is, it is possible to reduce the thickness of the assembling portion without providing a hole (hole) around the assembling portion as in the conventional case. Further, since the extending portion extends away from the portion extending along the terminal conductor (that is, the main body of the primary molded body), the function of holding the terminal conductor by the primary molded body is not impaired. Therefore, while improving the dimensional accuracy of the assembly portion, the productivity of the resin molded body can be improved as compared with the case where a hole (drilling) is provided around the assembly portion. Therefore, the resin molded body of this configuration can achieve both dimensional accuracy and productivity while having an assembly portion for assembling the sealing component.

上記［２］の構成の樹脂成形体によれば、端子導体を相手側端子などと接続するための端子の嵌合口（フード状の露出部）が、一次成形体の延出部に沿って延びる。フード状の露出部がこのように配置されているため、仮に従来のように組付部の周辺に穴（抜き）を設けようとすると、露出部が穴（抜き）のための金型（いわゆるスライド金型）を配置する妨げとなり易い。しかし、本構成の樹脂成形体では、一次成形体の延出部の働きにより、そもそも穴（抜き）を不要にし得る。そのため、本構成の樹脂成形体は、金型設計を過度に複雑にすることなく、フード状の露出部を上述したように配置できる。換言すると、フード状の露出部の配置等についての設計自由度が向上する。 According to the resin molded body of the above [2], the fitting opening (the hood-shaped exposed portion) of the terminal for connecting the terminal conductor to the mating terminal or the like extends along the extending portion of the primary molded body. .. Since the hood-shaped exposed portion is arranged in this way, if a hole (drilling) is to be provided around the assembling portion as in the conventional case, the exposed portion will be a mold (so-called) for the hole (drilling). It tends to hinder the placement of the slide mold). However, in the resin molded body having this configuration, the hole (punching) may be unnecessary in the first place due to the function of the extending portion of the primary molded body. Therefore, in the resin molded body of this configuration, the hood-shaped exposed portion can be arranged as described above without making the mold design excessively complicated. In other words, the degree of freedom in designing the arrangement of the hood-like exposed portion and the like is improved.

なお、本構成の樹脂成形体は、端子の嵌合口（フード状の露出部）が一次成形体の延出部の近傍に設けられる場合や一次成形体の延出部に隣接するように設けられる場合において、露出部の設計自由度の向上に特に貢献できる。ここで、「近傍」及び「隣接」とは、例えば、組付部（シール溝など）に仮に抜きを設ける場合、その抜きのための金型（スライド金型など）がフード状の露出部（嵌合口）に干渉し得る程度に、フード状の露出部と組付部との距離が短いことを表す。 In addition, the resin molded body of this configuration is provided in the case where the fitting opening (hood-shaped exposed portion) of the terminal is provided in the vicinity of the extended portion of the primary molded body or adjacent to the extended portion of the primary molded body. In this case, it can particularly contribute to the improvement of the design flexibility of the exposed portion. Here, "proximity" and "adjacent" means, for example, when a die is temporarily provided in an assembly portion (seal groove or the like), a die (slide die or the like) for the die is a hood-shaped exposed portion ( It means that the distance between the hood-like exposed part and the assembly part is short enough to interfere with the (fitting port).

上記［３］の構成の樹脂成形体によれば、一次成形体の延出部の延出端の端面の少なくとも一部が、二次成形体の組付部に沿った形状を有する。これにより、延出部が組付部（シール溝など）の形状を保持する芯材としても機能するため、組付部の寸法精度を更に向上できる。 According to the resin molded product of the above [3], at least a part of the end surface of the extension end of the extension part of the primary molded product has a shape along the assembly part of the secondary molded product. Accordingly, the extending portion also functions as a core material that holds the shape of the assembling portion (sealing groove or the like), so that the dimensional accuracy of the assembling portion can be further improved.

本発明によれば、シーリング部品を組み付ける組付部を有しながら寸法精度と生産性とを両立可能な樹脂成形体を提供できる。 Advantageous Effects of Invention According to the present invention, it is possible to provide a resin molded body that has both an dimensional accuracy and productivity while having an assembly portion for assembling a sealing component.

The resin molded body 1 is typically used as a relay connector that electrically connects the inside and outside of a box-shaped body in which a liquid such as lubricating oil is sealed, such as a vehicle transmission and a motor. It As shown in FIG. 1, the resin molded body 1 is used by being assembled into the box-shaped body 40 so as to be inserted into a mounting hole 41 (see FIG. 1B) provided in the wall of the box-shaped body 40. ..

以下、説明の便宜上、図１に示すように、「前後方向」、「幅方向」、「上下方向」、「前」、「後」、「上」、及び「下」を定義する。「前後方向」、「幅方向」及び「上下方向」は、互いに直交している。 Hereinafter, for convenience of description, as shown in FIG. 1, “front-back direction”, “width direction”, “up-down direction”, “front”, “rear”, “upper”, and “lower” are defined. The "front-back direction", "width direction" and "up-down direction" are orthogonal to each other.

図１〜図４に示すように、樹脂成形体１は、複数（本例では、４つ）の端子導体１０と、複数の端子導体１０に一体成形された一次成形体２０と、一次成形体２０に一体成形された二次成形体３０と、を備える。以下、樹脂成形体１を構成する各部材について順に説明する。 As shown in FIGS. 1 to 4, the resin molded body 1 includes a plurality of (four in this example) terminal conductors 10, a primary molded body 20 integrally molded with the plurality of terminal conductors 10, and a primary molded body. 20 and a secondary molded body 30 integrally molded.

The extending portion 22 is a portion that extends rearward from a position closer to the lower side in the vertical direction on the rear end surface (rectangular plane parallel to the vertical direction and the width direction) of the main body portion 21. By arranging the extending portion 22 in this manner, when the secondary molded body 20 is molded so as to cover the primary molded body 10, as shown in FIG. It is arranged on the side closer to the hood-shaped exposed portion 35 than the center of the main body portion 21 in the direction. An end surface 23 (see FIGS. 3B and 4) of the extending end of the extending portion 22 is curved so as to project in an arc shape (constituting a part of a cylindrical surface).

二次成形体３０は、典型的には、複数の金型を用いた射出成形により、複数の端子導体１０に一体化された一次成形体２０の周囲を一括して覆うように、端子導体１０及び一次成形体２０に一体化された樹脂成形体である。 The secondary molded body 30 is typically formed by injection molding using a plurality of molds so as to collectively cover the periphery of the primary molded body 20 integrated with the plurality of terminal conductors 10. And a resin molded body integrated with the primary molded body 20.

The main body portion 31 is a substantially rectangular parallelepiped portion that collectively covers the main body portion 21 of the primary molded body 20 and the vertical end portions of the main body portion 11 of the plurality of terminal conductors 10 and extends in the vertical direction.

円筒状部３２は、延出部２２全体を覆うように、本体部３１から径方向に円筒状に突出する部分である。フランジ部３３は、円筒状部３２の上側に連続して位置し、且つ、本体部３１から前後方向及び幅方向に矩形状に突出する部分である。フランジ部３３の四隅にはそれぞれ、上下方向に貫通する締結孔３３ａが設けられている。 The cylindrical portion 32 is a portion that radially protrudes from the main body portion 31 in a cylindrical shape so as to cover the entire extension portion 22. The flange portion 33 is a portion that is continuously located above the cylindrical portion 32 and that projects from the main body portion 31 in a rectangular shape in the front-rear direction and the width direction. Fastening holes 33a are provided at the four corners of the flange portion 33 so as to penetrate vertically.

上側露出部３４は、本体部３１の上端部から前側に矩形フード状に延びる部分である。上側露出部３４は、複数の端子導体１０の上端部１２を取り囲みながら外部に露出させている。上側露出部３４に設けられた開口である嵌合口３４ａ（図３（ａ）参照）は、箱状体４０の外側において相手側端子（図示省略）と接続するための嵌合箇所として機能する。下側露出部３５は、複数の端子導体１０の下端部１３を取り囲みながら外部に露出させている。下側露出部３５に設けられた開口である嵌合口３５ａ（図３（ａ）参照）は、箱状体４０の内側において相手側端子（図示省略）と接続するための嵌合箇所として機能する。 The upper exposed portion 34 is a portion that extends in a rectangular hood shape from the upper end of the main body 31 to the front side. The upper exposed portion 34 is exposed to the outside while surrounding the upper ends 12 of the plurality of terminal conductors 10. The fitting port 34a (see FIG. 3A), which is an opening provided in the upper exposed portion 34, functions as a fitting portion for connecting to a mating terminal (not shown) outside the box-shaped body 40. The lower exposed portion 35 is exposed to the outside while surrounding the lower end portions 13 of the plurality of terminal conductors 10. The fitting port 35a (see FIG. 3A), which is an opening provided in the lower exposed portion 35, functions as a fitting place inside the box-shaped body 40 for connecting to a mating terminal (not shown). ..

円筒状部３２の外周面の下側領域には、シーリング部品５０（図１（ｂ）及び図２（ｂ）参照）を組み付けるための環状溝３６が形成されている。ここで、一次成形体２０の延出部２２の延出端の端面２３（円筒面）と、環状溝３６の底面３６ａ（図４参照）と、の間における円筒状部３２（二次成形体３０）の肉厚ａ（図４参照）は、端面２３の周方向全域に亘って実質的に均一になっている。なお、肉厚ａが実質的に均一であるとは、二次成形体３０の成形時に生じ得る製造上の誤差（いわゆる製造ばらつき）の範囲内において肉厚ａが均一であることを表す。換言すると、肉厚ａが設計上で（例えば、設計図面に示される肉厚ａの数値が）均一であることを表す。本例では、肉厚ａは、２ｍｍ以下の実質的に均一な厚さとなっている。ここで、環状溝３６が形成された円筒状部３２の外周部が、本発明の「組付部」に対応している。 An annular groove 36 for assembling the sealing component 50 (see FIGS. 1B and 2B) is formed in the lower region of the outer peripheral surface of the cylindrical portion 32. Here, the cylindrical portion 32 (secondary molded body) between the end surface 23 (cylindrical surface) of the extended end of the extended portion 22 of the primary molded body 20 and the bottom surface 36a (see FIG. 4) of the annular groove 36. The wall thickness a of 30) (see FIG. 4) is substantially uniform over the entire area of the end face 23 in the circumferential direction. The fact that the wall thickness a is substantially uniform means that the wall thickness a is uniform within the range of manufacturing error (so-called manufacturing variation) that may occur during the molding of the secondary molded body 30. In other words, it means that the wall thickness a is uniform in design (for example, the numerical value of the wall thickness a shown in the design drawing). In this example, the thickness a is a substantially uniform thickness of 2 mm or less. Here, the outer peripheral portion of the cylindrical portion 32 in which the annular groove 36 is formed corresponds to the “assembly portion” of the present invention.

円筒状部３２の外周面の上側領域には、成形時のヒケの発生抑制用の径方向内側に窪んだ肉抜き穴３７が、周方向全域に亘って複数設けられている。また、円筒状部３２の下面における本体部３１より前側の位置（即ち、延出部２２と反対側の位置）にも、成形時のヒケの発生抑制用の上側に窪んだ肉抜き穴３８が設けられている。以上、樹脂成形体１を構成する各部材について説明した。 In the upper region of the outer peripheral surface of the cylindrical portion 32, a plurality of lightening holes 37, which are recessed radially inward for suppressing the occurrence of sink marks during molding, are provided over the entire circumferential direction. In addition, at the position on the lower surface of the cylindrical portion 32 on the front side of the main body portion 31 (that is, the position on the opposite side of the extending portion 22), there is also a hollowed-out hole 38 for suppressing the occurrence of sink during molding. It is provided. In the above, each member which comprises the resin molding 1 was demonstrated.

上記構成を有する樹脂成形体１を、図１に示す箱状体４０の取付孔４１に組み付ける際には、図２（ｂ）に示すように、シーリング部品５０が環状溝３６に組み付けられた樹脂成形体１（具体的には、円筒状部３２）を、上方から、フランジ部３３が箱状体４０の外表面に当接するまで、箱状体４０の取付孔４１に挿し込む。そして、締結孔３３ａ及び締結部材（図示省略）を利用して、フランジ部３３を箱状体４０に固定する。 When the resin molded body 1 having the above configuration is assembled in the mounting hole 41 of the box-shaped body 40 shown in FIG. 1, the sealing component 50 is assembled in the annular groove 36 as shown in FIG. 2B. The molded body 1 (specifically, the cylindrical portion 32) is inserted into the mounting hole 41 of the box-shaped body 40 from above until the flange portion 33 contacts the outer surface of the box-shaped body 40. Then, the flange portion 33 is fixed to the box-shaped body 40 by using the fastening hole 33a and the fastening member (not shown).

これにより、シーリング部品５０と取付孔４１の内周面とが周方向全域に亘って密着して箱状体４０の内部の潤滑油の漏れが抑制された状態で、樹脂成形体１が箱状体４０に組み付けられる。その後、箱状体４０に組み付けられた樹脂成形体１において、上側露出部３４の嵌合口３４ａに上側の相手側端子（図示省略）が接続され、下側露出部３５の嵌合口３５ａに下側の相手側端子（図示省略）が接続されることで、箱状体４０の内外が電気的に接続される。 As a result, the sealing component 50 and the inner peripheral surface of the mounting hole 41 are in close contact with each other over the entire circumferential direction, and the leakage of the lubricating oil inside the box-shaped body 40 is suppressed. It is assembled to the body 40. Then, in the resin molded body 1 assembled in the box-shaped body 40, the upper mating terminal 34a (not shown) is connected to the fitting port 34a of the upper exposed portion 34, and the lower side is fitted to the fitting port 35a of the lower exposed portion 35. The inside and outside of the box-shaped body 40 are electrically connected by connecting the mating terminal (not shown).

以上、本発明の実施形態に係る樹脂成形体１は、端子導体１０の本体部１１に沿って延びる一次成形体２０と、一次成形体２０を覆う二次成形体３０と、を備える。更に、一次成形体２０から端子導体１０の本体部１１の延びる方向とは異なる方向に延出部２２が延びており、この延出部２２を覆うように、二次成形体３０のシーリング部品５０を組み付けるための環状溝３６が形成される。そのため、一次成形体２０の延出部２２が存在しない場合に比べ、環状溝３６の底壁の厚さが小さくなる。即ち、従来のように環状溝の周辺に穴（抜き）を設けなくても、環状溝３６の底壁の薄肉化を実現できる。 As described above, the resin molded body 1 according to the embodiment of the present invention includes the primary molded body 20 extending along the main body portion 11 of the terminal conductor 10 and the secondary molded body 30 covering the primary molded body 20. Further, the extending portion 22 extends from the primary molded body 20 in a direction different from the direction in which the main body portion 11 of the terminal conductor 10 extends, and the sealing component 50 of the secondary molded body 30 covers the extended portion 22. An annular groove 36 for assembling is formed. Therefore, the thickness of the bottom wall of the annular groove 36 becomes smaller than that in the case where the extending portion 22 of the primary molded body 20 does not exist. That is, the bottom wall of the annular groove 36 can be thinned without providing a hole (hole) around the annular groove as in the conventional case.

また、延出部２２は、端子導体１０の本体部１１に沿って延びる一次成形体２０の本体部２１から離れるように延びているため、一次成形体２０による端子導体１０の保持機能を損なうこともない。よって、環状溝３６の寸法精度を高めながら、環状溝３６の周辺に穴（抜き）を設ける場合に比べて樹脂成形体１の生産性を向上できる。したがって、本構成の樹脂成形体１は、シーリング部品５０を組み付ける環状溝３６を有しながら寸法精度と生産性とを両立可能である。 Further, since the extending portion 22 extends away from the main body portion 21 of the primary molded body 20 that extends along the main body portion 11 of the terminal conductor 10, the function of holding the terminal conductor 10 by the primary molded body 20 may be impaired. Nor. Therefore, while improving the dimensional accuracy of the annular groove 36, the productivity of the resin molded body 1 can be improved as compared with the case where a hole (drilling) is provided around the annular groove 36. Therefore, the resin molded body 1 of this configuration can achieve both dimensional accuracy and productivity while having the annular groove 36 into which the sealing component 50 is assembled.

更に、端子導体１０を相手側端子などと接続するための端子の嵌合口３４ａ，３５ａ（フード状の露出部３４，３５）が、一次成形体２０の延出部２２に沿って延びている。そのため、従来のように環状溝の周辺に穴（抜き）を設けるとすると、フード状の露出部が延出部と異なる方向に延びる場合に比べ、露出部３４，３５が肉抜きのための金型（いわゆるスライド金型）を配置する妨げとなり易い。しかし、本構成の樹脂成形体１では、一次成形体２０の延出部２２の働きにより、そもそも肉抜きを不要にし得る。そのため、露出部３４，３５の設計自由度が向上する。 Further, terminal fitting openings 34a, 35a (hood-shaped exposed portions 34, 35) for connecting the terminal conductor 10 to a mating terminal or the like extend along the extending portion 22 of the primary molded body 20. Therefore, if a hole (hole) is provided around the annular groove as in the conventional case, the exposed portions 34 and 35 are made of metal for lightening the meat, as compared with the case where the hood-shaped exposed portion extends in a direction different from the extending portion. It easily hinders the placement of the mold (so-called slide mold). However, in the resin molded body 1 of the present configuration, the extension portion 22 of the primary molded body 20 may make it unnecessary in the first place to reduce the thickness. Therefore, the degree of freedom in designing the exposed portions 34 and 35 is improved.

更に、一次成形体２０の延出部２２の延出端の端面２３が、二次成形体３０の環状溝３６に沿った形状を有する。これにより、延出部２２が環状溝３６の形状を保持する芯材としても機能するため、環状溝３６の寸法精度を更に向上できる。 Furthermore, the end surface 23 of the extending end of the extending portion 22 of the primary molded body 20 has a shape along the annular groove 36 of the secondary molded body 30. Thereby, since the extending portion 22 also functions as a core material that holds the shape of the annular groove 36, the dimensional accuracy of the annular groove 36 can be further improved.

更に、一次成形体２０の延出部２２の延出端の端面２３と、環状溝３６の底面３６ａと、の間の肉厚ａ（図４参照）が２ｍｍ以下の実質的に均一な厚さとなっている。発明者による検討等によれば、樹脂成形体１の材料として一般に用いられる樹脂材料において、成形体の実質的な厚さが２ｍｍ以下にまで薄肉化されれば、設計上、成形収縮による変形（ヒケ）を実質的に無視し得ることが明らかになっている。よって、シーリング部品５０による封止性に特に影響を及ぼす環状溝３６の底壁の肉厚ａをこのような厚さにすることで、樹脂成形体１による封止性を更に向上できる。 Furthermore, the wall thickness a (see FIG. 4) between the end surface 23 of the extending end of the extending portion 22 of the primary molded body 20 and the bottom surface 36a of the annular groove 36 is a substantially uniform thickness of 2 mm or less. Has become. According to the study by the inventor, in the resin material generally used as the material of the resin molded body 1, if the substantial thickness of the molded body is reduced to 2 mm or less, the deformation due to the molding contraction ( It is clear that the sink mark can be virtually ignored. Therefore, by setting the wall thickness a of the bottom wall of the annular groove 36 that particularly affects the sealing performance of the sealing component 50 to such a thickness, the sealing performance of the resin molded body 1 can be further improved.

なお、本発明は、上述した実施形態に限定されるものではなく、適宜、変形、改良、等が可能である。その他、上述した実施形態における各構成要素の材質、形状、寸法、数、配置箇所、等は本発明を達成できるものであれば任意であり、限定されない。 It should be noted that the present invention is not limited to the above-described embodiment, and modifications, improvements, etc. can be appropriately made. In addition, the material, shape, size, number, arrangement position, etc. of each constituent element in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

例えば、上記実施形態に係る樹脂成形体１では、端子導体１０を相手側端子などと接続するための端子の嵌合口３４ａ，３５ａ（フード状の露出部３４，３５）が、一次成形体２０の延出部２２に沿って延びている。これに対し、嵌合口３４ａ，３５ａ（フード状の露出部３４，３５）が、一次成形体２０の延出部２２に沿う方向とは異なる方向に延びていてもよい。 For example, in the resin molded body 1 according to the above-described embodiment, the terminal fitting ports 34a and 35a (hood-shaped exposed portions 34 and 35) for connecting the terminal conductor 10 to the mating terminal or the like are the same as those of the primary molded body 20. It extends along the extending portion 22. On the other hand, the fitting openings 34a and 35a (the hood-shaped exposed portions 34 and 35) may extend in a direction different from the direction along the extending portion 22 of the primary molded body 20.

以下、図５及び図６を参照しながら、第１参考例に係る樹脂成形体２について述べる。図５及び図６に示すように、第１参考例に係る樹脂成形体２は、端子導体１０において、下端部１３が存在しない点（即ち、本体部１１の下端部が端子導体１０の下端部と一致する点）、一次成形体２０において、延出部２２が存在しない点、二次成形体３０において、下側露出部３５が存在しない点、一次成形体２０の本体部２１の下端部（及び、端子導体１０の本体部１１の下端部）が二次成形体３０の円筒状部３２の下端面から下方に突出している点、において、上記実施形態に係る樹脂成形体１と異なる。 Hereinafter, the resin molded body 2 according to the first reference example will be described with reference to FIGS. 5 and 6. As shown in FIGS. 5 and 6, in the resin molded body 2 according to the first reference example, the lower end portion 13 does not exist in the terminal conductor 10 (that is, the lower end portion of the main body portion 11 is the lower end portion of the terminal conductor 10 ). Point), the extension part 22 does not exist in the primary molded body 20, the lower exposed part 35 does not exist in the secondary molded body 30, the lower end portion of the main body portion 21 of the primary molded body 20 ( Also, the resin molded body 1 according to the above-described embodiment is different in that the lower end portion of the main body 11 of the terminal conductor 10 projects downward from the lower end surface of the cylindrical portion 32 of the secondary molded body 30.

図５及び図６に示す樹脂成形体２において、上記実施形態に係る樹脂成形体１の構成と同じ又は等価な構成については、樹脂成形体１において付された符号と同じ符号を付すことで、それらの説明に代える。 In the resin molded body 2 shown in FIGS. 5 and 6, the same or equivalent configuration as that of the resin molded body 1 according to the above-described embodiment is denoted by the same reference numeral as that of the resin molded body 1, Instead of those explanations.

ところで、樹脂成形体２の製造過程において、二次成形体３０を射出成形する際には、二次成形用の金型に対して一次成形体２０を相対移動しないように固定した状態で、当該金型の所定箇所に設けたゲートから樹脂材料を射出する必要がある。 By the way, in the process of manufacturing the resin molded body 2, when the secondary molded body 30 is injection-molded, the primary molded body 20 is fixed so as not to move relative to the mold for secondary molding. It is necessary to inject the resin material from a gate provided at a predetermined position of the mold.

ここで、二次成形用の金型に対して一次成形体２０を固定するため、図７に示す第２参考例のように、二次成形体３０（円筒状部３２）の下端面から下方に突出する一次成形体２０の本体部２１の下端部の外周面に環状の鍔部２４を設け、前・後・上・下・左・右の６方向それぞれから専用の金型を鍔部２４に押し付けることで（図７（ｂ）に示す白矢印を参照）、一次成形体２０の移動を規制する手法が考えられる。 Here, in order to fix the primary molded body 20 to the mold for secondary molding, as in the second reference example shown in FIG. 7, downward from the lower end surface of the secondary molded body 30 (cylindrical portion 32). An annular collar portion 24 is provided on the outer peripheral surface of the lower end portion of the main body portion 21 of the primary molded body 20 projecting to the front side, and a dedicated mold is provided from each of the front, rear, upper, lower, left, and right directions. A method of restricting the movement of the primary molded body 20 by pressing (see the white arrow shown in FIG. 7B) is conceivable.

これに対し、図５及び図６に示す樹脂成形体２では、図６に示すように、鍔部が設けられていない。樹脂成形体２の製造過程では、二次成形体３０（円筒状部３２）の下端面から下方に突出する一次成形体２０の本体部２１の下端部に、上方向を除いた前・後・下・左・右の５方向それぞれから専用の金型を押し付け（図６（ｂ）及び図６（ｃ）に示す白矢印を参照）、二次成形用の金型の上端位置に設けたゲートから樹脂材料を、ゲートの下方に位置する一次成形体２０に向けて射出する。 On the other hand, in the resin molded body 2 shown in FIGS. 5 and 6, as shown in FIG. 6, the collar portion is not provided. In the manufacturing process of the resin molded body 2, at the lower end of the main body 21 of the primary molded body 20 protruding downward from the lower end surface of the secondary molded body 30 (cylindrical portion 32), the front, rear, and A gate provided at the upper end of the die for secondary molding by pressing a dedicated die from each of the bottom, left, and right directions (see the white arrows shown in FIGS. 6(b) and 6(c)). The resin material is injected toward the primary molded body 20 located below the gate.

このとき、下向きの射出圧を受けて一次成形体２０が下方に押し付けられることで、一次成形体２０の上方向への移動が規制され得る。即ち、射出圧を利用することで、図７に示す第２参考例と比較して、上方向から一次成形体２０を押し付けるための専用の金型を省略することができる。 At this time, the primary molded body 20 is pressed downward by receiving the downward injection pressure, so that the upward movement of the primary molded body 20 can be restricted. That is, by using the injection pressure, it is possible to omit a dedicated mold for pressing the primary molded body 20 from above as compared with the second reference example shown in FIG. 7.
