  • Existing electronic devices primarily feature interfaces on the top, bottom, or front surfaces, and are arranged horizontally, meaning multiple interfaces are arranged horizontally, or in other words, parallel to the guide rails. Due to the limited size of the control cabinet, the guide rails are limited in length, and to ensure that wires and cables can be bent into the cable troughs with a large radius after being connected from the electronic device, sufficient space must be reserved around the guide rails. This results in insufficient space utilization when using existing electronic devices in control cabinets.
  • the length of the wiring port arranged horizontally on the electronic device housing must be less than the length of the guide rail occupied by the electronic device. Even if the guide rail is covered with electronic devices, the total length of the wiring port on the electronic device is still much less than the length of the guide rail. Even if the top and bottom surfaces of the housing are fully covered with wiring ports, the total length of the wiring port is only twice the length of the guide rail. The length of the wiring port on the electronic device determines the number of wiring terminals and also limits the upper limit of the expansion function of the electronic device.

Therefore, the space utilization rate of the control cabinet can be improved in a low-cost manner, providing the possibility and basis for the control cabinet to realize (expand) more functions.

  • the mounting portion 11 includes a mounting slot that extends laterally and penetrates both sides of the housing 10.
  • the mounting slot extends for the width of the rear side of the housing and is less than the length of the wiring port.
  • the mounting slot extends left and right on the rear side of the electronic device housing 10 and penetrates both sides of the housing 10, allowing the guide rail to pass through the mounting slot for securement when the electronic device is installed on the guide rail of a control cabinet.

  • the electronic device housing can be fabricated from sheet metal for ease of fabrication.
  • the housing comprises at least two sheet metal pieces, typically two, three, or four. These sheet metal pieces are joined together to form a housing cavity.
  • the wiring port 12 is formed on one or both of the sheet metal pieces.
  • FIG9a shows a scheme in which the housing is made of four sheet metal parts, two of which form the top panel and the bottom panel of the housing, respectively.
  • Two wiring ports 12 are respectively provided on the two sheet metal parts forming the top panel and the bottom panel, and can be formed by punching and cutting.
  • the other two sheet metal parts are bent to form two connected panels of the housing. Specifically, one sheet metal part is bent 90 degrees to form the front panel and the left panel, and the other sheet metal part is bent 90 degrees to form the rear panel and the right panel.

  • the hanging hole is used to fix the housing on the screw head of the guide rail.
  • Figures 9b-9e illustrate a housing constructed from two sheet metal parts. Each sheet metal part can form two or three adjacent panels of the housing. The specific configuration can be flexible based on actual needs and is not strictly limited here. Figures 9b-9e illustrate only a few of these scenarios. However, the total number of panels formed by the two sheet metal parts remains unchanged at six.
  • the two sheet metal parts are provided with a hem at the connection, and threaded screws are inserted through the hem after the hem overlaps with the edge of the panel, or the hem is nested and abutted, or a combination of the two to secure and connect the two.
  • the top panel and the bottom panel of the shell can be formed on the same sheet metal part or on two sheet metal parts. That is, when the top panel and the bottom panel of the shell are on the same sheet metal part, the wiring ports 12 are formed by openings at the corresponding top panel and bottom panel on the sheet metal part respectively; when the top panel and the bottom panel of the shell are on two sheet metal parts, the wiring ports 12 are formed by openings at the corresponding top panel and bottom panel on the two sheet metal parts respectively.
