Description

本発明は、ホースを一体に組み付け、射出成形により形成したコネクタに関する。   The present invention relates to a connector formed by injection molding by assembling a hose integrally.

従来、この種のコネクタとして、特許文献１の技術が知られている。すなわち、コネクタは、３方に分岐した分岐管を有するコネクタ本体と、各々の分岐管に接続されたホースと、コネクタ本体の分岐部の外側であってホースを挟むように射出成形された樹脂カバーとを備えている。分岐管の外周部には、ホースの内壁に組み込みかつ拡径する断面三角形の環状突部が形成されている。こうしたコネクタを製造するには、予め射出成形によりコネクタ本体を成形し、分岐管に各々のホースを挿入し、さらにホースの端部の外周面に樹脂カバーを射出成形により被覆することにより行なっている。   Conventionally, the technique of patent document 1 is known as this kind of connector. That is, the connector has a connector body having branch pipes branched in three directions, a hose connected to each of the branch pipes, and a resin cover that is injection molded so as to sandwich the hose outside the branch portion of the connector body. And. An annular protrusion having a triangular cross-section that is incorporated into the inner wall of the hose and expands in diameter is formed on the outer peripheral portion of the branch pipe. In order to manufacture such a connector, the connector main body is formed in advance by injection molding, each hose is inserted into the branch pipe, and the outer peripheral surface of the end portion of the hose is covered with a resin cover by injection molding. .

従来のコネクタでは、樹脂カバーによるホースを押さえる力がさほど大きくないために、ホースがコネクタ本体から抜けやすい。このため、ホースを分岐管とホースとの接続強度を大きくするために上記環状突部を大きくすると、ホースの挿入作業性が低下するという問題がある。   In the conventional connector, since the force for holding the hose by the resin cover is not so large, the hose is easily detached from the connector body. For this reason, if the said annular protrusion is enlarged in order to enlarge the connection strength of a hose and a branch pipe and a hose, there exists a problem that the workability | operativity of a hose falls.

（３） コネクタ１０の製造工程
図３ないし図６はコネクタ１０の製造工程を説明する説明図である。コネクタ１０は、樹脂の射出成形により成形される。図３において、まず、中子３０に内側挟持部材１３（図２）の一部を構成する内側連結部１５をセットする。中子３０は、コネクタ１０の内壁にほぼ倣った形状の外形を有しており、つまり順次縮径された円柱形状である、大径部３１、接続段部３２および小径部３３により形成されている。小径部３３にインサート部材として内側連結部１５がセットされる。このとき、小径部３３の外周を僅かに縮径することにより形成した位置決め段部３３ａに内側連結部１５の円筒部１５ａの内側端を突き当てて位置決めする。図４は内側連結部１５を示す斜視図である。内側連結部１５は、上述したように、円筒部１５ａと、円筒部１５ａの外周部から山脈状に拡径された拡張部１５ｂと、円筒部１５ａの一端から突設されたアンカー部１５ｃとを備えている。アンカー部１５ｃは、脚部１５ｄから爪１５ｅを軸心に向けて突設することにより形成されている。なお、アンカー部は、円筒部１５ａから突設した薄く肉の円筒形状などの各種の形状とすることができる。 (3) Manufacturing Process of Connector 10 FIGS. 3 to 6 are explanatory diagrams for explaining the manufacturing process of the connector 10. The connector 10 is molded by resin injection molding. In FIG. 3, first, the inner coupling portion 15 constituting a part of the inner clamping member 13 (FIG. 2) is set on the core 30. The core 30 has an outer shape that substantially follows the inner wall of the connector 10, that is, is formed by a large-diameter portion 31, a connection step portion 32, and a small-diameter portion 33 that are sequentially reduced in diameter. Yes. The inner connecting portion 15 is set as an insert member in the small diameter portion 33. At this time, the inner end of the cylindrical portion 15a of the inner connecting portion 15 is abutted against the positioning step portion 33a formed by slightly reducing the outer diameter of the small diameter portion 33 for positioning. FIG. 4 is a perspective view showing the inner connecting portion 15. As described above, the inner connecting portion 15 includes the cylindrical portion 15a, the expanded portion 15b that is expanded in a mountain shape from the outer peripheral portion of the cylindrical portion 15a, and the anchor portion 15c that protrudes from one end of the cylindrical portion 15a. I have. The anchor portion 15c is formed by projecting a claw 15e from the leg portion 15d toward the axis. The anchor portion can have various shapes such as a thin-walled cylindrical shape protruding from the cylindrical portion 15a.

続いて、図５に示すように、内側連結部１５を中子３０に位置決めした後に、その外周側にホースＨを圧入し、さらに、図６に示すように、組付体を金型４０にセットする。金型４０は、上型４１と下型４２からなり、その間にキャビティ４３を形成しており、キャビティ４３は、内側挟持部材１３を形成するためのキャビティ４３ａを備えている。そして、図示しない射出成形機から、キャビティ４３に溶融樹脂を射出する。内側連結部１５は、溶融樹脂と同じ樹脂材料であるから、キャビティ４３内に溶融樹脂が冷却固化することにより一体化してコネクタ１０が成形される。このとき、キャビティ４３ａ内に溶融樹脂が流れ込み、内側連結部１５の内側に入り込んだ樹脂により内側基部１４が形成される。   Subsequently, as shown in FIG. 5, after positioning the inner connecting portion 15 on the core 30, the hose H is press-fitted into the outer peripheral side, and the assembly is attached to the mold 40 as shown in FIG. 6. set. The mold 40 includes an upper mold 41 and a lower mold 42, and a cavity 43 is formed between the upper mold 41 and the lower mold 42, and the cavity 43 includes a cavity 43a for forming the inner clamping member 13. Then, molten resin is injected into the cavity 43 from an injection molding machine (not shown). Since the inner connecting portion 15 is made of the same resin material as the molten resin, the molten resin is cooled and solidified in the cavity 43 to be integrated to form the connector 10. At this time, the molten resin flows into the cavity 43 a, and the inner base portion 14 is formed by the resin that has entered the inner connection portion 15.

（４） コネクタ１０の作用・効果
（４）−１ コネクタ１０は、コネクタ本体１１の一端部から円筒形状の外側挟持部材１２および内側挟持部材１３を突設し、外側挟持部材１２と内側挟持部材１３との間にホースＨを挟持することにより、一体的にホースＨを組み付けている。よって、射出成形によってホースＨがコネクタ１０に一体化するからホースＨの挿入作業がなくなり、生産性に優れている。
（４）−２ 内側挟持部材１３の内側連結部１５は、射出成形の際のインサート部材として用い、アンカー部１５ｃが内側基部１４の一部で囲まれることで内側連結部１５との一体性を高めている。しかも、アンカー部１５ｃは、インサート部材としての内側連結部１５に形成しているから、複雑な形状であっても成形することが容易であり、射出成形時の金型の構成も複雑にする必要がない。

Therefore, since the hose H is integrated with the connector 10 by injection molding, the operation of inserting the hose H is eliminated, and the productivity is excellent.
(4) -2 The inner coupling portion 15 of the inner clamping member 13 is used as an insert member at the time of injection molding, and the anchor portion 15c is surrounded by a part of the inner base portion 14 so that the integrity with the inner coupling portion 15 is achieved. It is increasing. Moreover, since the anchor portion 15c is formed in the inner connecting portion 15 as an insert member, it is easy to mold even if it has a complicated shape, and the configuration of the mold at the time of injection molding needs to be complicated. There is no.
(4) -3 The extended portion 15 b of the inner connecting portion 15 prevents the hose H from being pulled out by entering the inner wall of the hose H. Since the extended portion 15b is formed in the inner connecting portion 15 as an insert member in the same manner as the anchor portion 15c, it is easy to mold even if it has a complicated shape, and the configuration of the mold during injection molding There is no need to make it complicated.
