本考案は、電気器具における電源コード取付装
置、さらに詳しくは電源コードに作用する外力が
器内の配線に及ばない電源コードの取付溝造に関
する考案である。[Detailed description of the invention] [Field of industrial application] The present invention relates to a power cord attachment device for electrical appliances, and more specifically to a power cord attachment groove structure that prevents external forces acting on the power cord from reaching the wiring inside the appliance. It is an idea.
従来、電気器具の電源コードは、器具の壁面に
穿設した貫通孔に電源コードを通したゴム製のコ
ードブツシユを嵌着し、電源コードを固定してい
た。
Conventionally, power cords for electrical appliances have been secured by fitting a rubber cord bushing into which the power cord is passed through a through hole drilled in the wall of the appliance.
また、コードブツシユの一部に一体のヒレ部を
設け、該ヒレ部を利用してコードとコードブツシ
ユを結束する思想（実公昭53−44738号公報）が
知られている。 There is also a known idea (Japanese Utility Model Publication No. 53-44738) in which a part of the cord bushing is provided with an integral fin and the fin is used to bind the cord and the cord bush.
さらに、コードを円弧状の溝に嵌め込み、溝の
両端部における締め付けによる摩擦抵抗によつて
外力を受け止めようとする思想（実開昭49−
124901号公報）なども知られている。 Furthermore, the idea was to fit the cord into an arc-shaped groove and absorb external force through the frictional resistance caused by tightening at both ends of the groove (1983-
124901) are also known.
従来のものでは組立時に電源コードをコードブ
ツシユに嵌挿し、かつ滑りにくいゴム製のコード
プツシユを器具の貫通孔に無理嵌めしなければな
らず、作業が厄介であつた。
In the conventional device, during assembly, the power cord had to be inserted into the cord bush, and the non-slip rubber cord bush had to be force-fitted into the through hole of the device, making the work cumbersome.
また、コードブツシユと器具の貫通孔との嵌着
状態が緩い場合は、電源コードに外力が作用した
ときに、コードブツシユが抜けてしまつたり、電
源コード自身がコードブツシユの存在にかかわら
ず摺動し、器内の接触不良や断線といつた故障を
起こす危険性があつた。 In addition, if the cord bushing is loosely fitted into the through hole of the device, the cord bushing may come off when an external force is applied to the power cord, or the power cord itself may slide regardless of the presence of the cord bushing. There was a risk of failure such as poor contact or disconnection inside the device.
さらに、円弧状の溝に嵌め込まれたコードと、
溝の両端部における締め付けによる摩擦抵抗によ
つて外力を受けるものでは、荷重がコードの一点
に集中しやすく、コード自体が断線する可能性が
あつた。 Furthermore, a cord fitted into an arc-shaped groove,
In the case where external force is applied due to frictional resistance due to tightening at both ends of the groove, the load is likely to be concentrated at one point on the cord, and there is a possibility that the cord itself may break.
本考案は、上記欠点に鑑み、コードブツシユを
使わないで組立作業を簡素化し、しかも、電源コ
ードを器具に確実に固定し、電源コードに作用す

In order to solve the above problems, this invention creates a through hole 5 in the wall surface 2a of the electric appliance for introducing the power cord A into the appliance, and makes the power cord A go around behind the through hole 5. The column 6 and the column 6 for
A holding wall surface 7 is provided on the outer periphery of the column body with a gap X into which the power cord A can be inserted between the support wall surface 7 and the outer circumferential surface of the column body. A pair of holding pieces 8 and 9 are provided in front of the column 6 to hold the power cord A in a state where it is wound around the column. One of the holding pieces 8 and 9 has a through hole 5.
and the column 6, the other holding piece 9 is placed at a position where the power cord introduced into the vessel from the through hole 5 is bent at an obtuse angle toward the column. Place it in a position where it is bent at an acute angle toward the inside of the container. Furthermore, the surface of the gap X is covered with a flat member such as the back cover 12 and fixed with screws.
A plurality of protrusions 11 are provided on the bottom surface 10 of the flat member, and protrusions 15 are provided on the surface of the flat member in opposite directions, so that these protrusions 11 and 15 are in contact with the surface of the power cord.
電源コードＡを電気器具に組み込むには、貫通
孔より器内に導入した電源コードを、保持壁面７
との間に嵌入しながら柱体６を周回させ、先端を
内部の入力端子に接続する。
To incorporate the power cord A into the appliance, insert the power cord into the appliance through the through hole, and insert it into the retaining wall surface 7.
The column 6 is rotated while being inserted between the two, and the tip is connected to the input terminal inside.
器内に導入された電源コードＡは柱体を周回

比較的広い一定の角度周回されているため、外力
は、周回角度全体の摩擦力によつて完全に受け止
められ、器内の配線などには影響しない。 When external force (tension) is applied to power cord A,
The external force acts as a frictional force between the surface of the power cord and the surface of the column. At this time, since the power cord is wrapped around the column at a relatively wide fixed angle, the external force is completely absorbed by the frictional force over the entire rotation angle, and does not affect the wiring inside the device.
電源コードの張力、すなわち外力が無くなつた
場合、柱体に周回されている電源コードに緩みを
生じ、改めて張力が作用したときに位置ずれを起
こす可能性がある。ところが、本考案では保持壁
