    • A frame for a switchgear cabinet is made up of frame members and corner joints. The corner joints are provided with plug-in rods in sockets and are joined to the frame members. The frame members are designed as open hollow sections that are bent several times, are symmetrical to their diagonal and open in the area of their inner sides. The section sides of the frame member continuing beyong its outer perpendicular section sides are bent inwards several times to form sockets for the plug-in rods of a corner joint. The resulting sockets provide at least two points of contact with the insert plug-in rods spanning more than 180 DEG . This yields a frame with hollow sections that are easy to manufacture, with low expenditures for parts and assembly.
    • 开关柜的框架由框架构件和角接头组成。 角接头在插座中设有插入式杆,并与框架构件连接。 框架构件被设计成敞开的空心部分,其弯曲数次,对称于其对角线并且在其内侧区域敞开。 框架构件的与其垂直外侧边连续的截面侧向内弯曲数次以形成用于角接头的插入杆的插座。 所得到的插座提供至少两个跨接超过180°的插入式插入杆的接触点。 这产生了一个空心型材的框架,易于制造,零件和装配费用低。
