Abstract
An important part of an industrial appliance is its constructive mount on the DIN rail, which allows not only to significantly save space in the shields and cabinets, but also save time and effort spent on the installation of devices. This is especially true when it comes to the equipment of a large industrial cabinet, which takes a lot of time to install the devices, if they are fastened with screws (for comparison: it takes just a few seconds to secure the device to the DIN rail). DIN rail is called a special metal profile, which is used for the installation of devices in the electrical industry. This profile is used for fixing various modular equipment (automatic switches, protective devices, contactors, electric meters, relays of various purpose, terminals, electrical sockets, etc.) when placed in electrical shields of different types. Wide introduction of DIN rails simultaneously with the minimization of all elements that are traditionally used in electrical engineering, has allowed a fundamentally new approach to the installation of equipment. With such a unified approach in the panel cases of a typical size it is possible to place quite complicated devices and devices that use modern microelectronics built into their work. However, due to the improper design of the latch mount on the DIN rail, which causes large backlash between the side faces of the valve and the housing, there is a problem of moving the device housing along the DIN rail. The article deals with the drawbacks in the existing designs of latch devices for mounting with DIN rail, on the basis of which new constructive solutions of latches for mounting the device housing on a DIN rail, taking into account the established requirements for the coefficient of strength and shear strength. The strength of DIN-rail mountings with the help of SolidWorks software is evaluated.
