Abstract

Description

具有整体接地引脚的密封压缩机
技术领域
本发明涉及密封压缩机供电及接地方式的改进。
背景技术
密封压缩机用于许多制冷压缩机应用场合。通常将一压缩机泵装置和一电动机密封在一机体内。致冷剂被引入机体内并能在机体内流至泵装置。
由于致冷剂能在机体内流动，故该机体必须在任何开口处装设流体式密封装置。一个对密封造成困难问题的开口是供电用开口。
与这种压缩机配套的电动机通常是三相电源电动机。在三相电动机中，有三根不同的电源线通进压缩机。
在现有技术中，系将一分开的接地线装在压缩机壳体上并装在连接装置上。该分开的接地线就需要一些不希望的额外装配。此外，这些额外的电线很容易移位，而这是不希望的。
发明内容
在本发明的一个已揭示的实施例中，系与电气连接装置本身一体地提供一电气接地。具体地说是在该电连接装置内装设四个引脚。这些引脚中的三个与三相电动机用三相电源配接。第四个引脚为接地引脚。该接地引脚与一接受所有四个引脚的钢板电气连接。其它三个引脚则与该钢板绝缘。该钢板被焊接到压缩机机体上。因此，从接地引脚到钢板为直接连接，然后与压缩机机体连接，以提供一适当的接地。
另一方面，没有可移位的分开的电线。此外，在进行其他电气连接时，最终接地连接即自动寮现。故简化了装配。
具体地说，本发明提供一种压缩机，包括：一密封的压缩机机体；一接受三相电源即旋转驱动的电动机；一包括有一由所示电动机驱动的轴的泵单元；以及一用于将三相电力供至所示压缩机的电源连接装置，所述电源连接装置包括：三个与一电源连接以供给三相功率的终端电源接头，以及一个在所述电源连接装置中包括与接地连接的接地接头的第四个终端接头，所述接地接头与所述压缩机体整体接地，其特征在于，所述接地接头延伸到所述机体内并在所述机体内部提供一关于所述四个接头中哪个是所述接地接头的可见指示。
本发明的进一步的特点是四个引脚的内端与接地引脚不同。即向装配者提供一种关于四个引脚中哪一个为接地的指示，以使该装配者能容易地在电动机控制装置与电源之间装配电线。
在一较佳实施例中，将终端的接地引脚制成比其它引脚短。这样可使装配者对四个引脚中哪一个为接地引脚一目了然。
从以下的说明和附图可最好地理解本发明的这些和其它特点。
附图说明
图1示出一采用本发明的涡卷压缩机。
图2为本发明电气连接部的放大图。
图3为一与图2垂直的横剖面图。
具体实施方式
图1表示一具有一机体21的、已密封的压缩机20，该机体中容置有一电动机22和一泵装置24，该泵装置在该应用中最好为一涡卷压缩机；但本发明可延伸到其它类型的已密封压缩机。
如图1所示，一电气连接装置26容置在机体21的一外壳壁25内。如虚线所示，该电气连接装置示意性地接受电源29，并延伸到电源31。电源31将三相交流电供给电动机22。机体21内还包括有一合适的电动机控制装置27，电线28从连接装置26连接到控制装置27。
如图2所示，连接装置26包括一被焊入侧壁21内的钢环27。多个引脚30在该钢环27内延伸到一内端32。内端32通过延伸到电动机控制装置的电线28加以连接。
一用于提供接地的终端引脚包括一内端34。特别是内端34短于内端32。当一装配者正在将电线28装入压缩机时，该装配者将容易地对哪一个引脚接地的指示一目了然。因此，装配者将不会因疏忽而将电源线装到接地引脚33上。
绝缘体可以是陶瓷绝缘体36，它围绕引脚30而不是引脚33。因此，引脚30与环27隔开但引脚33并不与环27隔开。环27被焊接到机体21上，而壳体接合即完成了引脚33与机体21之间的电气连接。
当装设连接装置26时，通过引脚33接受一合适的接地连接装置，以将电气接地线和所有三个电源线连接到压缩机。
本发明通过在原先制作电气连接装置时就整体制作连接装置来简化接地引脚与一密封压缩机的装设。通过采用容置在供电至壳体引脚的环内的引脚，本发明无须任何分开的接地元件。另外通过为装配者提供哪一个引脚为接地引脚的指示还可简化装配。
以上虽然揭示了一较佳实施例，便熟悉本领域的普通技术人员应认识到在本发明范围内还可作某些修改。为此，应研究以下的权利要求以确定本发明的真实范围和内容。
