具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、 “外”、“顺时针”、“逆时针”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括至少一个该特征。在本发明的描述中，“多个”的含义是至少两个，例如两个，三个等，除非另有明确具体的限定。
在本发明中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”、“固定”等术语应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接或彼此可通讯；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本发明中的具体含义。
下面参考图1-图7详细描述根据本发明实施例的压缩机100，其中压缩机100使用CO2冷媒，压缩机100可以为立式压缩机或者卧式压缩机，压缩机100也可以为旋转式压缩机、涡旋式压缩机或者叶片式压缩机等。具体地，压缩机100可以应用在高铁、飞机、坦克、轮船、大巴车、家用轿车、航天飞机、空间站、卫星等设有空调的设备上。
如图1-图5所示，根据本发明实施例的压缩机100，包括：壳体1、接线端子2和电控装置3，其中壳体1上设有多个间隔设置的壳体通孔10。当然可以理解的是，壳体1上还设有吸气口11和排气口12。
接线端子2包括固定座20和多个接线柱21，固定座20固定在壳体1上，固定座20上设有多个安装通孔，多个接线柱21分别一一对应地设在多个安装通孔内，多个接线柱21与多个壳体通孔10一一对应设置，每个接线柱21穿过相应的壳体通孔10，每个接线柱21的外周壁和安装通孔的内周壁之间设有绝缘材料件22，每个接线柱21对应的绝缘材料件22延伸至相应的壳体通孔10内，也就是说，通过绝缘材料件22，每个接线柱21与壳体1和固定座20之间绝缘设置。电控装置3与多个接线柱21相连。可选地，绝缘材料件22为玻璃绝缘材料件，从而使得绝缘材料件22的成本低且绝缘原理可靠。
可以理解的是，如图1所示，压缩机100还包括电机6、泵体组件7等元件，泵体组件7包括曲轴72、气缸70和主轴承71等元件，电机6包括定子60和转子61，定子60固定在壳体1的内壁上，转子61固定在曲轴72上，电机6通过连接线路与多个接线柱21相连。
下面对压缩机100使用CO2冷媒时的工作压力和压缩机使用其他冷媒例如为R410A冷媒时的工作压力进行比较，如下表所示：
冷媒 R410A CO2(R744)
吸气压力Mpa 0.5 4.5
排气压力Mpa 2.8 14.5
壳体爆破耐压Mpa 15 46.5
由上可知，当压缩机100使用CO2冷媒时，压缩机100的工作压力为使用其他冷媒时的大约5倍，接线端子2承受的外力F由1.7KN扩大至9KN。其中F＝P*S，P为工作压力，S为端子承受压差面有效横截面积。
由上述计算公式可知，若想改善接线端子2承压能力，可从以下手段：①减小横截面积S；②减小压力P；③增加壳体1与接线端子2强度。现有的壳体上的用于安装接线端子2的端子孔为一个通孔，且端子孔的直径约为28mm，则所对应面积为S＝28*28/4*3.14＝615mm2。
下面以壳体1上设置三个壳体通孔10为例进行说明，即将现有技术中的一个大端子孔改设置为3个小通孔，三个接线柱21分别通过对应的小通孔，则壳体通孔10的直径可设置为6mm，所对应承受压差的有效截面积S1为S1＝6*6/4*3.14*3＝84mm2，则本发明的接线端子2受力F1＝P*S1＝14.5*84＝1.2KN，如下表所示；
Figure PCTCN2017072521-appb-000001
由上分析可知，本发明的接线端子2承受的压力远远小于现有技术的接线端子承受的压力。
根据本发明实施例的压缩机100，通过在壳体1上设置多个壳体通孔10，每个接线柱21穿过相应的一个壳体通孔10，从而可以降低接线端子2承受的压力，保证耐压要求，同时由于多个壳体通孔10间隔设置，可以进一步提高壳体1的强度，保证压缩机100的工作可靠性。
如图4所示，在本发明的一些实施例中，每个壳体通孔10与相应的绝缘材料件22的外周壁之间具有间隙。从而便于接线端子2的安装。
在本发明的具体示例中，如图3、图4和图7所示，多个接线柱21上的绝缘材料件22间隔设置。从而当其中一个接线柱21上的绝缘材料件22发生破损等问题时，可以只针对相应的绝缘材料件22进行维护，可以降低维护成本且可以节省绝缘材料件22的制造成本，降低压缩机100的成本。
如图1-图3所示，在本发明的一些具体示例中，固定座20固定在壳体1的内壁上。当 然可以理解的是，固定座20也可以固定在壳体1的外壁上。可选地，固定座20焊接固定在壳体1上。
可选地，壳体1的内壁上设有用于放置固定座20的凹槽。从而便于固定座20的安装。
如图1所示，根据本发明的一些实施例，压缩机100还包括盖板4，盖板4设在壳体1的外周壁上且与壳体1之间限定出放置空间5，电控装置3放置在放置空间5内。从而不仅可以将电控装置3集成在壳体1上，减小压缩机100的体积，还可以对电控装置3起到保护的作用，延长电控装置3的使用寿命。
在本发明的一些实施例中，如图1所示，压缩机100还包括分隔板8，分隔板8与壳体1配合以将壳体1内分隔出低压腔13和高压腔14，吸气口11与低压腔13连通，高压腔14与排气口12连通，电机6设在低压腔13内，泵体组件7设在高压腔14内，气缸70上的吸气入口与低压腔13连通，曲轴72伸入到低压腔13内以与转子61配合,分隔板8上设有装配通孔，装配通孔与主轴承71的外周壁密封配合。
具体而言，电机6运行时会产生一定的热量，从吸气口11进入到低压腔13内的低压冷媒中的液态冷媒会在电机6散出的热量作用下汽化，从而可以降低吸入到气缸70内的冷媒中的液态冷媒含量，可以在一定程度上避免压缩机100发生液击现象。同时由于从气缸70排出的冷媒先排入到高压腔14后再从排气口12排出，冷媒可以在高压腔14内进行油气分离，从而可以降低排气口12的排油量，同时高压腔14还可以起到降噪的作用。又由于通过设置分隔板8，可以避免主轴承71由于压力差而发生变形，避免气缸70因主轴承71变形而变形，提高压缩机100运行的可靠性。
当气缸70为两个时，至少一个气缸70的吸气入口与低压腔13连通。当每个气缸70的吸气入口均与低压腔13连通时，从吸气口11进入到低压腔13内的低压冷媒分别排入到每个气缸70内进行压缩。当其中一个气缸70的吸气入口与低压腔13连通时，从吸气口11进入到低压腔13内的低压冷媒先排入到其中一个气缸70中进行压缩，从上述气缸70排出的经过一次压缩后的冷媒排入到另一个气缸70内进行第二次压缩。
根据本发明实施例的车辆，包括根据本发明上述实施例的压缩机100。
根据本发明实施例的车辆，通过设置上述的压缩机100，可以降低接线端子2承受的压力，保证耐压要求，可以进一步提高壳体1的强度，保证压缩机100的工作可靠性。
在本发明中，除非另有明确的规定和限定，第一特征在第二特征“上”或“下”可以是第一和第二特征直接接触，或第一和第二特征通过中间媒介间接接触。而且，第一特征在第二特征“之上”、“上方”和“上面”可是第一特征在第二特征正上方或斜上方，或仅仅表示第一特征水平高度高于第二特征。第一特征在第二特征“之下”、“下方”和“下面”可以是第一特征在第二特征正下方或斜下方，或仅仅表示第一特 征水平高度小于第二特征。
