従来から固定子には、異常時の安全保護のため、安全保護装置を取り付ける必 要があり、固定子巻線に安全保護装置を固定用結束バンド等により固定する構造 が多く用いられている。 以下図面を参照しながら、上述した従来の固定子巻線における安全保護装置の 取付構造の一例について説明する。 図４は従来の安全保護装置を備えた固定子を示すものである。 図４において、１は固定子鉄心、２は固定子巻線、４は安全保護装置、１２は結 束バンドであり、固定子巻線２に安全保護装置４を固定している。 １３は電源用リ−ド線、１４は絶縁保護チュ−ブであり、固定子巻線の巻線端 １０と電源用リ−ド線１３及び安全保護装置用リ−ド線５等の接続部の絶縁保護 をしている。 １５は結束糸で、安全保護装置用リ−ド線、固定子巻線の巻線端１０、絶縁保 護チュ−ブ１４等を固定子巻線２に縛って固定している。 以上の様な構成において固定子巻線２に異常が発生した時、固定子巻線２に固 定された安全保護装置４が固定子巻線２の温度上昇により作動し、燃焼等の異常 事態を防止する機能を持たしている。 Conventionally, it is necessary to attach a safety protection device to the stator for safety protection in the event of an abnormality, and a structure in which the safety protection device is fixed to the stator winding with a binding band or the like is often used. An example of a mounting structure of the above-mentioned conventional safety protection device in the stator winding will be described below with reference to the drawings. FIG. 4 shows a stator provided with a conventional safety protection device. In FIG. 4, 1 is a stator core, 2 is a stator winding, 4 is a safety protection device, and 12 is a binding band, and the safety protection device 4 is fixed to the stator winding 2.

しかしながら上記の様な構成においては、電動機組立上、固定子巻線は所定寸 法内におさめる必要があり、安全保護装置を取り付ける前に固定子巻線の取り付 け箇所部の巻線高さの整形修正を行わねばならず、又結束バンドにて安全保護装 置の固定子巻線への固定には熟練が必要であり、工程の作業性が悪い。 一方、安全保護装置の取り付け箇所の巻線高さの整形修正により固定子巻線にレ ア−ショ−ト等が発生したり、又結束バンドによる局部的な力により、安全保護 装置が誤動作するという品質的問題点を有していた。 本考案はかかる従来の課題を解消するため、製造工程の簡略化とレア−ショ− ト及び安全保護装置の誤動作等の品質的問題を低減する固定子における安全保護 装置の取付構造を提供するものである。 However, in the above-mentioned configuration, the stator winding must be kept within the specified dimensions in the assembly of the motor, and the height of the winding at the mounting location of the stator winding must be adjusted before installing the safety protection device. It is necessary to reshape and fix it, and fixing the safety protection device to the stator winding with a binding band requires skill and the workability of the process is poor. On the other hand, due to shaping correction of the winding height at the location where the safety protection device is attached, the stator winding may cause raratio, etc., or the local force of the binding band may cause the safety protection device to malfunction. There was a quality problem. In order to solve the conventional problems, the present invention provides a mounting structure for a safety protection device in a stator that simplifies the manufacturing process and reduces quality problems such as rare shots and malfunction of the safety protection device.

本考案は、上記した様に、端子ケ−スに設けた収納部に安全保護装置と安全保 護装置用リ−ド線を収納固定することにより、従来、固定子巻線へ安全保護装置 や安全保護装置用リ−ド線を固定するために使用していた結束バンドや結束糸が 不要となり、又従来行っていた固定子巻線を所定寸法内におさめるための、安全 保護装置の取り付け箇所部の固定子巻線高さの整形修正工程が不要になる等、そ の製造工程が簡略化される。 As described above, according to the present invention, the safety protection device and the lead wire for the safety protection device are housed and fixed in the housing portion provided in the terminal case as described above, so that the safety protection device and the safety wire for the stator winding are conventionally provided. The binding band and binding thread used to secure the lead wire for the safety protection device are no longer required, and the location of the safety protection device to keep the stator winding within the specified dimensions is eliminated. The manufacturing process is simplified, such as eliminating the step of shaping and adjusting the height of the stator winding.

以下、本考案の一実施例の端子ケ−スにおける安全保護装置の取付構造につい て図面を参照しながら説明する。 図１、図２は、本考案の一実施例における固定子鉄心に端子ケ−スを取り付け た状態の要部平面図と要部正面図である。 図３は、本考案の一実施例における固定子鉄心に端子ケ−スを取り付けた状態 を示す側面断面図である。 図１〜図３において、１は固定子鉄心、２は固定子巻線、３は固定子鉄心に固 定された樹脂製の端子ケ−ス、４は安全保護装置、５は安全保護装置用リ−ド線 である。 ６は固定子巻線に近接して端子ケ−ス３に設けた安全保護装置４と安全保護装 置用リ−ド線５を収納するための収納部で、安全保護装置用リ−ド線側には空隙 部７を設ける。 以上の構成によれば、端子ケ−スの収納部６には安全保護装置４を収納固定す るとともに、固定子巻線２の温度を直接感知する安全保護装置４の感温部が露出 できるように固定子巻線２と近接して対向される箇所は開放状態とし、固定子巻 線との間にシリコン等の熱伝導性の良い樹脂８を注ぎ込んで温度検出精度を良く する。 一方、安全保護装置用リ−ド線５を収納固定する収納部６の空隙部７の固定子 巻線側は密閉状態とし、安全保護装置用リ−ド線５が固定子巻線２とは直接接触 しない構造となっているので、安全保護装置４及び安全保護装置用リ−ド線５の 固定用の結束バンド及び結束糸が不要となり、また固定子巻線２を所定寸法内に おさめるための、固定子巻線２の整形修正工程が不要となる等、製造工程が簡略 化される。 Hereinafter, a mounting structure of a safety protection device in a terminal case according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 and FIG. 2 are a plan view and a front view of an essential part of a stator core in which a terminal case is attached according to an embodiment of the present invention. FIG. 3 is a side sectional view showing a state in which a terminal case is attached to a stator core according to an embodiment of the present invention. 1 to 3, 1 is a stator core, 2 is a stator winding, 3 is a resin terminal case fixed to the stator core, 4 is a safety protection device, and 5 is a safety protection device. It is a lead line. Reference numeral 6 denotes a storage portion for accommodating the safety protection device 4 and the safety protection device lead wire 5 provided in the terminal case 3 in the vicinity of the stator winding, and is a lead wire for the safety protection device. A space 7 is provided on the side. According to the above configuration, the safety protection device 4 is housed and fixed in the housing 6 of the terminal case, and the temperature sensing part of the safety protection device 4 that directly senses the temperature of the stator winding 2 can be exposed. As described above, the portion closely facing the stator winding 2 is opened, and a resin 8 having good thermal conductivity such as silicon is poured between the stator winding 2 and the stator winding to improve temperature detection accuracy. On the other hand, the stator winding side of the void portion 7 of the housing portion 6 for housing and fixing the lead wire 5 for the safety protection device is in a hermetically sealed state, and the lead wire 5 for the safety protection device is different from the stator winding 2. Since the structure does not come into direct contact, the binding band and the binding thread for fixing the safety protection device 4 and the lead wire 5 for the safety protection device are not required, and the stator winding 2 is kept within the specified dimensions. In addition, the manufacturing process is simplified by eliminating the need for the shaping process of the stator winding 2.
【０００７】 また、収納部の空隙部７には安全保護装置用リ−ド線５を保持するためと案内 用に突起部９を設けているので、安全保護装置用リ−ド線が端子に接続しやすく 保持でき、また、収納部６は有底形状のため、安全保護装置用リ−ド線５は固定 子鉄心１と固定子巻線２にも接触しない構造となるため、耐熱製の安全保護装置 用リ−ド線も絶縁保護チュ−ブも必要としない。 また、固定子巻線の巻線端１０は、端子ケ−ス３に収納されているＬ字形状の 端子１１の一端にヒュ−ジングにて接続する構成となつているため、従来のよう に結束糸にて、安全保護装置用リ−ド線、固定子巻線の巻線端、絶縁保護チュ− ブのそれぞれを固定子巻線に固定する必要がなくなる。Further, since the protruding portion 9 is provided for holding the lead wire 5 for the safety protection device and for guiding in the void portion 7 of the accommodating portion, the lead wire for the safety protection device serves as a terminal. It is easy to connect and can be held. In addition, since the storage part 6 has a bottomed shape, the lead wire 5 for the safety protection device has a structure in which it does not contact the stator core 1 and the stator winding 2 either. Neither lead wires for safety protection devices nor insulation protection tubes are required. Further, since the winding end 10 of the stator winding is connected to one end of the L-shaped terminal 11 housed in the terminal case 3 by fusing, as in the conventional case. It is not necessary to fix the lead wire for the safety protection device, the winding end of the stator winding, and the insulation protection tube to the stator winding with the binding yarn.

上述の様に本考案は、安全保護装置を取り付ける為に端子ケ−スに安全保護装 置および安全保護装置用リ−ド線を収納する収納部を設けて、収納固定する取付 構造を採用することにより、固定用の結束バンドや結束糸及び巻線の整形修正工 程が不要となる等製造工程の簡略化がはかれると共に、その製造工程の簡略化に よるレア−ショ−ト不良及び安全保護装置誤動作等の不良低減を実現することが できる。 また、安全保護装置用リ−ド線が固定子鉄心にも固定子巻線にも接触しない構 造のため、耐熱製のリ−ド線も絶縁保護チュ−ブも必要としない電動機を提供で きる。 As described above, the present invention adopts the mounting structure in which the terminal case is provided with the accommodating portion for accommodating the safety protection device and the lead wire for the safety protection device in order to mount the safety protection device, and the storage case is fixed. This simplifies the manufacturing process, such as eliminating the need for a binding band for fixing, and the process of shaping and fixing the binding yarn and winding, and at the same time simplifies the manufacturing process to prevent faults and safety protection. It is possible to reduce defects such as device malfunctions. Further, since the lead wire for the safety protection device does not come into contact with the stator core or the stator winding, it is possible to provide an electric motor that does not require a heat-resistant lead wire or an insulation protection tube.
