【考案の詳細な説明】
本考案は、たとえば工作機械の配電盤、操作盤あるいは
各種電気装置などにおけるコード配線接続部に使用され
るコードホルダーに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cord holder used for cord wiring connections in, for example, power distribution panels, operation panels, or various electrical devices of machine tools.
従来、この種のコードホルダーは、第1図に示すように
、硬質合成樹脂材料で形成されたねじ部1とフランジ部
2とを有する全体略円筒状の取付固定体3と、この取付
固定体3のフランジ部2側の端部に連設されかつ先端に
向って内径が小さくなるように軟質合成樹脂材料で形成
された中空筒体4とからなり、前記中空筒体4を取付固
定体3の内周面を介して取付固定体3の開口端部側まで
延長し、その先端に形成されたフランジ5によって取付
固定体3と中空筒体4とが一体的に結合されている。Conventionally, as shown in FIG. 1, this type of cord holder includes a mounting fixture 3 having a generally cylindrical overall shape and having a threaded portion 1 and a flange portion 2 made of a hard synthetic resin material, and this mounting fixture. A hollow cylindrical body 4 formed of a soft synthetic resin material is connected to the end on the flange portion 2 side of 3 and the inner diameter becomes smaller toward the tip.The hollow cylindrical body 4 is attached to the fixed body 3. The mounting and fixing body 3 and the hollow cylinder body 4 are integrally connected by a flange 5 that extends to the open end side of the mounting and fixing body 3 through the inner circumferential surface of the flange 5 and is formed at the tip thereof.
そして、コードホルダーの取付固定体3を各種機器のコ
ード配線接続部に固定し、また中空筒体4を用途に応じ
たコードの内径に合わせて切断して使用することにより
、コードホルダーに挿通されたコードの接続部分を保護
し、断線や接触不良などを防止するように構成されてい
る。The cord holder mounting fixing body 3 is fixed to the cord wiring connection part of various devices, and the hollow cylindrical body 4 is cut according to the inner diameter of the cord according to the purpose. It is designed to protect the connecting part of the cord and prevent disconnection and poor contact.
しかしながら、このような構造では、予め成形した取付
固定体3を金型に嵌め込んで沖空筒体4を成形する際中
空筒体4のフランジ5を形成するために取付固定体3と
金型との間に間隙を設けなければならず、取付固定体3
の嵌め込み作業が面倒で、作業時間がかかりすぎる欠点
があった。However, in such a structure, when the pre-formed mounting fixture 3 is fitted into a mold to form the offshore cylinder 4, the mounting fixture 3 and the mold are used to form the flange 5 of the hollow cylinder 4. A gap must be provided between the mounting fixture 3 and
The problem was that the fitting work was troublesome and took too much time.
また、中空筒体4に取付固定体3の内周面を介してフラ
ンジ5を形成するため材料が多く必要であり、さらに取
付固定体3と中空筒体4との結合を中空筒体4のフラン
ジ5で行なっているため結合状態が弱く、コードに衝撃
が加わりコードが強く引張られると中空筒体4が取付固
定体3から外れてしまうことがあった。In addition, a large amount of material is required to form the flange 5 on the hollow cylindrical body 4 through the inner circumferential surface of the mounting fixture 3, and furthermore, the connection between the mounting fixture 3 and the hollow cylindrical body 4 is difficult. Since this is done by the flange 5, the connection state is weak, and if an impact is applied to the cord and the cord is strongly pulled, the hollow cylinder 4 may come off from the mounting fixed body 3.
そこで、取付固定体3と中空筒体4とを確実に組合させ
る目的で、第2図に示すように、取付固定体3のフラン
ジ部2の側面に複数の孔6を形成し、中空筒体4を成形
する際前記孔6によってフランジ部2のねじ部1側に環
状部7と中空筒体4と一体に形成し、これにより取付固
定体3と中空筒体とを結合した構造のコードホルダーが
考えられる。Therefore, in order to ensure that the mounting fixture 3 and the hollow cylindrical body 4 are combined, a plurality of holes 6 are formed in the side surface of the flange portion 2 of the mounting fixture 3, as shown in FIG. When molding the cord holder 4, the annular part 7 and the hollow cylinder 4 are integrally formed on the threaded part 1 side of the flange part 2 through the hole 6, thereby connecting the mounting fixing body 3 and the hollow cylinder. is possible.
しかしながら、このような構造のコードホルダーでは、
成形時に環状部7形戒用の材料がねじ部1のねし山に流
れ込み、固まってしまうため、は゛り取り作業が必要と
なる不都合があった。However, in a cord holder with this structure,
During molding, the material for the annular part 7 flowed into the threads of the threaded part 1 and hardened, resulting in the inconvenience of requiring stripping work.
したがって、取付固定体3のねじ部に円筒状の補助部材
を螺合し、この補助部材とともに取付固定体3を金型に
嵌め込んでねじ部1を保護する成形方法も考えられるが
、この場合には補助部材をねじ部1に螺合しなければな
らず、取付固定体3を金型に嵌め込む作業が面倒となり
、作業能率が悪くなる。Therefore, a molding method may be considered in which a cylindrical auxiliary member is screwed onto the threaded portion of the mounting/fixing body 3, and the mounting/fixing body 3 is fitted into a mold together with this auxiliary member to protect the threaded portion 1. In order to do this, an auxiliary member must be screwed into the threaded portion 1, and the work of fitting the mounting and fixing body 3 into the mold becomes troublesome, resulting in poor work efficiency.
このため、通常の成形用金型A、Bのほかに、第2図に
示すように、環状部形成用の金型Cを別に用意してねじ
部への流入を防止することも考えられるが、この場合に
は金型A、B、Cの成形が面倒であり、また金型の抜き
方向も複雑で、特別に成形機を用意する必要があり、さ
らに金型の接合部が多いためにばつが発生し易い等の不
具合がある。Therefore, in addition to the normal molding molds A and B, it may be possible to prepare a separate mold C for forming the annular part, as shown in Fig. 2, to prevent the flow from flowing into the threaded part. In this case, molding of molds A, B, and C is troublesome, the direction of mold removal is also complicated, a special molding machine needs to be prepared, and there are many joints in the mold, so There are problems such as the possibility of rashes.
