Definitions

  • the present invention relates to a module for use in a control apparatus of an industrial machine having a terminal block, and more particularly to a module for use in a control apparatus of an industrial machine, which can be securely fixed to a rail with a simplified structure.
  • the use of input and output terminal modules is on the rise in control apparatuses of the industrial machines for executing data transmission between the control apparatuses, such as, for example, servers, vendors, PLCs, PCs, sensors, actuators, and the like.
  • Such modules for the control apparatuses of the industrial machines have been widely used to constitute open networks since they exhibit not only simplicity in wiring systems, but also expediency in repair of the control apparatuses connected to one another through networks .
  • the modules are configured in such a fashion that terminal blocks are detachably coupled to an upper side of the modules, respectively, and each of the terminal blocks has a plurality of input and output terminals arranged at an upper surface thereof, and a plurality of connectors arranged at a lower surface thereof .
  • connection between a plurality of the modules is achieved as they are coupled to a rail so that the input and output terminals of the modules are interconnected.
  • the terminals are attached to a printed circuit board provided inside the respective modules.
  • the terminals have front connector pieces formed at a front end thereof, and pairs of rear connector pieces formed at a rear end thereof, such that each of the front connector pieces of one module is inserted between a pair of the rear connector pieces of another terminal.
  • the modules cannot be securely fixed to the rail of the control apparatus, there always exists a risk of unintentional separation of the modules from the rail or distortion of the modules when vibrations are generated during operation of the industrial machines, resulting in short-circuit in connections between the modules. Therefore, in order to prevent the above unintentional separation and distortion problems of the modules, the modules have to be securely fixed to the rail by means of separate fastening means, such as bolts. However, this means that separate tools are required in order to separate the modules from the rail, and thus causes inconvenience in installation and separation of the modules .
  • the rail is conventionally fabricated through drawing and thus unavoidably exhibits low accuracy in shape and dimension thereof, when the modules are installed to the rail having such an inaccurate shape and dimension, they cannot be securely fixed to the rail.
  • the vibrations generated during the operation of the industrial machines worsen the damage to the coupling portions, unavoidably resulting in frequent exchange of the terminal blocks and modules .
  • the terminals attached to the printed circuit boards have only low support force, if a pressure is caused as the front connector pieces are inserted between pairs of the rear connector pieces, and is applied to the terminals, the terminals may be easily distorted or separated from the printed circuit boards, thereby being short-circuited. Since the front connector pieces have to be repeatedly inserted between pairs of the rear connector pieces when a plurality of the modules are coupled to one another, this may cause the rear connector pieces to be loosened, resulting in a poor connection problem. Finally, in a state wherein the front connector pieces are inserted between the rear connector pieces, since the front and rear connector pieces produces a frictional force therebetween due to the vibrations generate during the operation of the industrial machines, they tend to be easily damaged.
