具体实施方式
下面结合附图和具体实施例对本发明的技术内容做进一步的详细说明。
如图1和图2所示，本发明所提供的高压电源和X射线管的连接装置 包括第一连接单元100和第二连接单元200，第一连接单元100用于安装在高压电源上并连接高压电源的高压输出端，作为高压电源的输出端，第二连接单元200安装在X射线管上并连接X射线管的阴极，作为X射线管的电源输入端；将第一连接单元100与第二连接单元200之间涂抹足量硅胶后，可拆卸地插接在一起，并挤出两者之间的空气，使得高压电源和X射线管可拆卸地连接在一起。
具体的说，第一连接单元100可以嵌装在高压电源外壳内，或者第一连接单元100还可以与高压电源的第一固定件对接，使得第一连接单元100位于高压电源固定件的外侧。那么，与第一连接单元100进行插接的第二连接单元200的结构与第一连接单元相契合，下面通过具体的实施例对第一连接单元100和第二连接单元200的结构进行详细说明。
实施例1
如图1～图3所示，本实施例所提供的第一连接单元100采用嵌装在高压电源外壳1内；该第一连接单元100，包括嵌装在高压电源外壳内的第一外壳7，在第一外壳7的一端分别设置高压电源输出端子(相当于插座)4，第一外壳7的另一端的端口截面与高压电源外壳的端口的第一固定件8的截面齐平，并与第一固定件8固定在一起。其中，第一外壳7由非金属材料制成。
如图2和图3所示，在本实施例中，为了保证局部电场的均匀性，还可以在高压电源输出端子4的外围设置第一屏蔽环5。第一屏蔽环5为由金属材料制成的带导向柱的金属屏蔽环。
如图3所示，高压电源输出端子4可以直接连接或通过电缆3连接高压电源的高压模块2，作为高压电源的输出端，用于输出预设高压。其中，根据实际需要，确定高压电源输出端子4与高压模块2之间的连接是采用电缆连接的方式还是直接连接的方式。
其中，第一外壳7的长度需要满足爬电距离的要求，即沿着第一外壳7设置高压电源输出端子的一端到高压电源外壳1的端口的第一固定件8之间的距离满足爬电距离的要求。并且，第一外壳7的长度根据高压模块2实际需要输出的高压进行调整，以1KV高压对等1mm长度的第一外壳7为原则，确定第一外壳7的长度。例如，高压模块2实际需要输出的高压为5KV时，第一外壳7的长度可以为5mm。
其中，第一固定件8设置有与第一外壳7端口连通的通孔，该通孔的形状和尺寸与第一外壳7端口相同，使得第一外壳7可以从通孔嵌装到高压电源外壳内。在第一连接单元100嵌装在高压电源外壳1后，将第一外壳7与高压电源外壳1之间的空间进行高压绝缘处理，如填充高压油或者高压绝缘胶等绝缘填充物(如图3示出的绝缘填充物6)。
需要说明的是，实际加工时，可以根据用户实际需求，采用一体成型技术将第一外壳7与第一固定件8、高压电源外壳1加工成一体；如果将第一外壳7设置有高压电源输出端子4和第一屏蔽环5的一端配合第一固定件8的通孔嵌入高压电源外壳内，第一外壳7的另一端的端口与第一固定件8可以采用无缝连接的方式固定在一起，此种连接方式为现有成熟工艺技术，在此不再详述。
如图1、图2和图4所示，第二连接单元200与X射线管外壳的第二固定件15连接。具体的说，第二连接单元200，包括第二外壳12，在第二外壳12的一端分别设置电源输入端子9(相当于插头)和第二屏蔽环10，第二外壳12的另一端与X射线管外壳的第二固定件15固定在一起。其中，第二外壳12由非金属材料制成。并且，第二外壳12的形状和尺寸与第一外壳7相吻合，电源输入端子9和第二屏蔽环10同样对应与高压电源输出端子4和第一屏蔽环5相吻合；如图5所示，第二外壳12及其上设置的电源输入端子9可以可拆卸地与第一外壳7及其上设置的高压输出端子4插接在一起。
如图1和图4所示，在本实施例中，为了保证局部电场的均匀性，还可以在电源输入端子9的外围设置第二屏蔽环10。第二屏蔽环10为由金属材料制成的带导向柱的金属屏蔽环。
如图4所示，电源输入端子9可以直接连接或通过电缆11连接X射线管管芯14的阴极，作为X射线管的电源输入端，用于接收所需的高压。其中，根据实际需要，确定电源输入端子9与X射线管管芯14之间的连接是采用电缆连接的方式还是直接连接的方式。
其中，如图1和图4所示，第二固定件15设置有用于固定X射线管管芯14阳极的通孔，该通孔的形状和尺寸与X射线管管芯14阳极的形状和尺寸相同，使得X射线管管芯14的阳极可以从通孔穿出后，可以采用无缝连接的方式与第二固定件15固定在一起。当安装完X射线管管芯14 后，将第二外壳12的电源输入端子9连接X射线管管芯14的阴极，然后将第二外壳12套接在X射线管管芯14的外部，并采用无缝连接的方式与第二固定件15固定在一起后，将第二外壳12与X射线管管芯14之间的空间进行高压绝缘处理，如填充高压油或者高压绝缘胶等绝缘填充物(如图4示出的绝缘填充物13)。此外，实际加工时，还可以根据用户实际需求，采用一体成型技术将第二外壳12、X射线管管芯14及第二固定件15加工成一体。
本实施例中，当需要采用高压电源为X射线管提供高压时，只需将安装在X射线管上的第二连接单元200与安装在高压电源上的第一连接单元100分别涂抹足量硅胶后，插接在一起，并采用螺栓将第一固定件8与第二固定件15固定在一起，并挤出两者之间的空气，防止高压电源发生放电现象的同时，使得高压电源与X射线管固定在一起。当高压电源或X射线管发生故障时，只需取下第一固定件8与第二固定件15上的螺栓，将X射线管从高压电源上拨出，实现高压电源与X射线管的分开，从而便于分别对高压电源与X射线管进行故障检测与维修。因此，高压电源与X射线管采用此种方式连接在一起，不仅减小了高压电源与X射线管的安装体积，还便于高压电源与X射线管任意一个发生故障时的拆装检修。
实施例2
该实施例所提供的第一连接单元100和第二连接单元200的结构与实施例1的不同之处在于：将高压电源安装的第一连接单元100插接到X射线管安装的第二连接单元200上，实现高压电源与X射线管连接在一起；将第一连接单元100从第二连接单元200拔出，实现高压电源与X射线管的分开；即实施例2所提供的第一连接单元100和第二连接单元200的连接方式与实施例1相反。
因此，结合如图1～图5，不难想象出实施例2中的第一连接单元100的结构与实施例1中的第二连接单元200类似，采用将第一连接单元100与高压电源外壳的第一固定件连接。第二连接单元200与实施例1中的第一连接单元100类似，采用第二连接单元200嵌装在X射线管外壳内；具体的说，在第一连接单元100中，在第一外壳的一端分别设置高压电源输出端子(相当于插头)，第一外壳的另一端与高压电源外壳的第一 固定件的外侧对接。
在本实施例中，为了保证局部电场的均匀性，同样可以在高压电源输出端子的外围设置第一屏蔽环。
其中，第一固定件设置的与第一外壳端口连通的通孔，该通孔用于实现高压电源输出端子可以直接连接或通过电缆连接高压电源的高压模块。采用无缝连接的方式将高压电源外壳、第一外壳分别与第一固定件固定在一起后，将高压电源外壳与第一外壳之间的空间进行高压绝缘处理，如填充高压油或者高压绝缘胶。此外，实际加工时，还可以根据用户实际需求，采用一体成型技术将第一外壳、高压电源外壳及第一固定件加工成一体。
在本实施例所提供的第二单元中，在第二外壳的一端分别设置电源输入端子(相当于插座)，第二外壳的另一端的端口截面与X射线管外壳的第二固定件的截面齐平，并与第二固定件固定在一起。其中，第二固定件设置有与第二外壳端口连通的通孔，该通孔的形状和尺寸与第二外壳端口相同，实现将第二外壳嵌装在X射线管的外壳内，并将第二外壳与X射线管外壳之间的空间进行高压绝缘处理，如填充高压油或者高压绝缘胶。此外，电源输入端子与X射线管管芯的阴极采用的连接方式同实施例1，在此不再赘述。
在本实施例中，为了保证局部电场的均匀性，同样可以在电源输入端子的外围设置第二屏蔽环。
同样，实际加工时，可以根据用户实际需求，采用一体成型技术将第二外壳、第二固定件、X射线管外壳加工成一体；在将第二外壳设置有电源输入端子和第二屏蔽环的一端从第二固定件的通孔嵌入X射线管外壳内，第二外壳另一端的端口与第二固定件可以采用无缝连接的方式固定在一起。
本实施例中，当需要采用高压电源为X射线管提供高压时，只需将安装在高压电源上的第一连接单元100与安装在X射线管上的第二连接单元200分别涂抹足量硅胶后，插接在一起，并采用螺栓将第一固定件与第二固定件固定在一起，并挤出两者之间的空气，防止高压电源发生放电现象的同时，使得高压电源与X射线管固定在一起。当高压电源或X射线管发生故障时，只需取下第一固定件与第二固定件上的螺栓， 将高压电源从X射线管上拨出，实现高压电源与X射线管的分开，从而便于分别对高压电源与X射线管进行故障检测与维修。因此，高压电源与X射线管采用此种方式连接在一起，不仅减小了高压电源与X射线管的安装体积，还便于高压电源与X射线管任意一个发生故障时的拆装检修。
实施例3
