【考案の詳細な説明】
本考案は、ミシン用整流子電動機をミシン頭部へ取付け
るための取付板上にねし止めにより固定された後栓受へ
、ミシン頭部に内蔵された照明用ランプのリード線を接
続する機構に関するものである。[Detailed description of the invention] This invention is based on the idea that a lighting lamp built into the sewing machine head is attached to the rear stopper holder which is fixed with screws on the mounting plate for attaching the commutator motor for the sewing machine to the sewing machine head. This relates to a mechanism for connecting lead wires.
一般に第１図に示すようにミシン用電動機１には、後栓
受２を介して電源３および電動機の速度を制御するため
のコントローラ４が接続される。Generally, as shown in FIG. 1, a sewing machine electric motor 1 is connected via a rear stopper 2 to a power source 3 and a controller 4 for controlling the speed of the electric motor.
さらにミシン頭部に内蔵された照明用ランプ５は後栓受
に設けられた端子にランプリード線６を接続することに
より電源と電気的に接続される。Further, an illumination lamp 5 built into the head of the sewing machine is electrically connected to a power source by connecting a lamp lead wire 6 to a terminal provided on the rear plug holder.
従来は、第２図〜第４図に示すように電動機７をミシン
頭部に取付るための取付板８上に合成樹脂製絶縁板９を
介して電動機７のリード線１０を接続した後栓受１１を
ねじ１２により固定するのが、一般的であった。Conventionally, as shown in FIGS. 2 to 4, a rear plug is used in which a lead wire 10 of the motor 7 is connected via a synthetic resin insulating plate 9 to a mounting plate 8 for mounting the motor 7 to the sewing machine head. It has been common practice to fix the receiver 11 with screws 12.
しかし、ミシンメーカー或はミシン販売店によりミシン
のランプリード線を後栓受１１に接続する場合、後栓受
固定ねじ１２をはずし、ライプリード線を決められた端
子にねし止めしていた。However, when a sewing machine manufacturer or a sewing machine retailer connects the lamp lead wire of the sewing machine to the rear plug holder 11, the rear plug holder fixing screw 12 is removed and the lamp lead wire is screwed to a predetermined terminal.
従ってランプリード線を接続する場合、後栓受１１を取
付板８からはずし、またねし止め固定するという作業が
必要で大変手間がかかつていた。Therefore, when connecting the lamp lead wire, it is necessary to remove the rear plug holder 11 from the mounting plate 8 and fix it with screws, which is very time-consuming.
本考案は上記の欠点を除去し、容易に後栓受へランプリ
ード線を固定するものである。The present invention eliminates the above-mentioned drawbacks and easily fixes the lamp lead wire to the rear plug holder.
以下本考案の一実施例を第５図、第６図を参照して説明
する。An embodiment of the present invention will be described below with reference to FIGS. 5 and 6.
図において、１２は鉄板により形成された取付板である
。In the figure, 12 is a mounting plate formed of an iron plate.
この取付板１２には、ミシン頭部にねし止め固定するた
めの長孔１３と電動機を取付けるための長孔１４と後栓
受を取付けるためのねし孔１５およびランプリード線を
後栓受の端子に導くのを見るための透視孔１６を有して
いる。This mounting plate 12 has a long hole 13 for fixing it to the sewing machine head with screws, a long hole 14 for attaching the electric motor, a threaded hole 15 for attaching the rear plug holder, and a lamp lead wire to the rear plug holder. It has a see-through hole 16 for viewing the lead to the terminal.
一方、絶縁板１７は、透明の絶縁合成樹脂により形成さ
れ、接栓管固定用ねじのための丸孔１８と後栓受のラン
プ端子にランプリード線を固定する端子ねじ１９を締付
けるドライバー用孔２０を有している。On the other hand, the insulating plate 17 is made of transparent insulating synthetic resin, and includes a round hole 18 for a screw for fixing a plug pipe and a hole for a screwdriver for tightening a terminal screw 19 for fixing a lamp lead wire to a lamp terminal of a rear plug holder. It has 20.
後栓受２１の端子部２２は、導電性金属よりなす、リー
ド線２３を挿入する横穴２４とそのリード線２３を押圧
固定するための端子ねじ１９が横穴２４と９０°の位置
に形成されている。The terminal portion 22 of the rear plug holder 21 has a horizontal hole 24 made of a conductive metal into which a lead wire 23 is inserted, and a terminal screw 19 for press-fixing the lead wire 23 at a position of 90 degrees to the horizontal hole 24. There is.
以上のような構成であるため、取付板１２に絶縁板１７
を介してねじにより固定された後栓受２１の端子へのラ
ンプリード線２３を接続する場合取付板１２の孔１６を
通して透明の絶縁板１７により、見ながら端子の横孔２
４ヘランプリード線２３を挿入することができ、絶縁板
１７のドライバー用孔２０から、容易にドライバーによ
りねじ締を行うことが出来る。Because of the above configuration, the insulating plate 17 is attached to the mounting plate 12.
When connecting the lamp lead wire 23 to the terminal of the rear plug holder 21 fixed with a screw through the transparent insulating plate 17 through the hole 16 of the mounting plate 12,
A four-heramp lead wire 23 can be inserted, and screws can be easily tightened with a screwdriver through the screwdriver hole 20 of the insulating plate 17.
従って、ミシンメーカー或はミシン販売店により、ラン
プリード線を電動機の取付板上に取付られた後栓受の端
子へ接続する場合、後栓受の取りはずし再固定が不要と
なり、非常に容易にすることができる。Therefore, when a sewing machine manufacturer or a sewing machine retailer connects the lamp lead wire to the terminal of the rear plug holder mounted on the motor mounting plate, it is not necessary to remove and re-fix the rear plug holder, making it very easy. be able to.
