Abstract

本发明的封闭式电动压缩机的保护器备置有保护器主体，包覆该主体由耐热温度为155℃以上的耐热绝缘材料组成的绝缘外套，上述绝缘外套系电芳酰胺纸组成，可以起到耐住密闭容器焊接时的耦射热的效果。而且，绝缘外套的端部用超声波溶敷成袋状，不需用粘接剂。即使在制冷剂环境中使用，也可以防止化学的事故。

Description

本发明涉及装载于封闭式电动压缩机的电动机中、改进安装方法的电流温度感应式过负荷保护器。
封闭式电动压缩机为在过负荷运转情况下，在感应电动机温度和制冷剂气体温度的同时，根据所感应过电流断开电动机电源，以防止烧坏电动机，而在该封闭式电动压缩机容器内装载电流温度感应式过负荷保护器（以下简单称之为保护器）。
图5-图10展示了例如在日本实用新型公开公报昭56-175581号所示、先有的封闭式电动压缩机内部装载式保护器的安装方法的一个实例。保护器（5）用连接扎线（4）固定在电动机末端线圈（3）的表面上。
图5、图6、图8是将保护器装配到电动机末端线圈（3）上端部的实例，图9、图10展示了将保护器装配到电动机末端线圈（3）侧面部分的实例。
图7表示先有的保护器（5），由于保护器（5）的主体为充电部分，所以用聚酯薄膜等硬质薄膜材料制成的绝缘外套（6）予以覆盖起来。绝缘外套（6）面向保护器（5）用聚酯薄膜缠绕粘结成两端开放的圆筒形，如图5如示，由于要确保绝缘空间距离等，所以绝缘外套（6）的尺寸l1一般为保护器（5）的尺寸l0的1.5-2倍长。
在装配电动机末端线圈时由于绝缘外套难于变形，所以l1的长度是必需的。
因为封闭式电动压缩机通常是非常小型化的，所以在电动机末端线圈（3）上安装的保护器（5）存在尺寸方面的困难。
同时，由于靠近形成封闭容器的上部（1）与下部（2）的焊接位置，所以作为先有的保护器（5）的绝缘外套（6）一般所使用的聚酯薄膜，在容器焊接时由于辐射热而熔化，存在最后失去绝缘功能的问题。
本发明的目的在于为解决上述问题，提供安装容易、耐热性优良的绝缘外套的保护器。
按照本发明的封闭式电动压缩机的保护器，备置保护器主体、覆盖该主体的由耐热温度为155℃以上的耐热绝缘材料如芳酰胺纸组成的绝缘外套。上述绝缘外套若采用芳酰胺（ァラシツド）纸是很有效的。
并且，绝缘外套即使用超声波熔化端部也行。
由于本发明的封闭式电动压缩机的保护器采用了耐热温度为155℃以上的耐热材料的绝缘外套，因此，即使在靠近保护器位置处焊接压缩机密闭容器的上部与下部焊接时也不会被辐射热熔化而失去绝缘功能。
并且，由于用超声波熔化绝缘外套，所以不需使用粘合剂等有机材料就可以形成绝缘外套。
图1是表示本发明一实施例的封闭式电动压缩机的水平剖视图，
图2是表示图1的保护器安装实例的侧视图，
图3是表示图1的保护器的正面图，
图4是表示图1的保护器安装实例的封闭式电动压缩机的纵向剖视图，
图5是表示装配先有保护器的封闭式电动压缩机的水平剖视图，
图6是表示图5的保护器安装实例的侧面图，
图7是表示图5的保护器正面图，
图8、图9是表示图5的保护器安装实例的封闭式电动压缩机的剖面图，
图10是从图9P方向所见到的部分扩大图。
图中，（5）是保护器（保护器主体），（6）是绝缘外套。
还有，在各图中用相同标号表示同一或相当部分。
下面根据图1-图4对本发明的一实施例进行说明。用连接扎线（4）将作为保护器主体的保护器（5）固定的电动末端线圈（3）的表面上。
图3表示本发明的保护器（5）、由于保护器（5）的主体是充电部分，所以覆盖了绝缘外套（6）。绝缘外套（6）系以芳酰胺纸芳香族聚酰胺加工成形为圆筒状，把该圆筒端部做成袋状将保护器（5）收纳于其中，用超声波在焊缝部分（8a）、（8b）进行熔敷而成。
装配到电动机末端线圈（3）时，如图1所示，对比保护器（5）的尺寸l0，由于扎线（4）能使绝缘外套（6）轻易地变形，所以绝缘外套（6）的装配尺寸l2变成大致与l0的尺寸相同。
虽然在上述实施例中，示出的绝缘外套（6）的材料采用了芳酰胺纸，但只要具有155℃以上的耐热性，所用材料并不局限于此，例如，采用聚酰亚胺也可以。
本发明的保护器是由主体、耐热温度为155℃以上的耐热绝缘材料所组成覆盖住该主体的绝缘外套构成的，所以具有耐住密闭容器焊接时的辐射热的效果。
又由于用了芳酰胺纸的绝缘外套可以起到同样的效果。而且，因为在绝缘外套的端部用超声波熔敷成袋状，所以不需要粘接剂，即使以制冷环境中使用，也可以防止化学事故。
