Definitions

  • the present invention relates to a connection terminal for electrical equipment, comprising a cage, a contact pad and a clamping screw.
  • connection terminals of certain electrical equipment are provided with a bar, called a screen, intended to prevent an incorrect connection of a cable by introducing the stripped end of this cable into an opening in the terminal cage.
  • a bar called a screen
  • the cage In the case where the cage is movable, it moves when the cable previously tightened in a suitable opening is tightened by means of a screw. This displacement of the cage clears a space of which access can be taken accidentally for an opening of the cage. Such an error results in a deficient, even dangerous, connection.
  • the present invention proposes to overcome this drawback by providing a standard connection terminal which can be used with or without a screen according to the needs linked to the envisaged application.
  • connection terminal is characterized in that the cage is equipped with a removable screen, and connecting means arranged to allow the establishment of said screen.
  • the cage is provided with connecting means arranged to allow the positioning by snap-fastening of said screen produced in one piece in the form of a rigid plate.
  • the screen consists of two or more elements sliding one relative to the other. It can also consist of one or more retractable flexible elements.
  • connection terminal 10 comprises a cage 11, a contact pad 12 and a clamping screw 13.
  • the cage 11 is preferably made of aluminum from a profile produced by stretching and of which the inner walls are threaded to be able to receive the clamping screw 13.
  • latching means being in the form of two lateral protrusions 14, arranged to cooperate with two hooks 15 of a screen removable 16 which can be attached, if necessary or useful for the electrical assembly carried out.
  • This screen is advantageously made of a synthetic material and the hooks 15 have sufficient elasticity to be able to snap onto the lateral protuberances 14.
  • FIG. 1 shows the cage provided with the screen.
  • Figure 4 shows the cage not equipped with the screen.
  • FIG. 2 represents the cage fitted with the screen and used as the terminal of an electrical apparatus 20 for connecting a cable 17 of large diameter. In this case, the screen occupies a relatively low position, since the stripped end 17a of the cable 17 occupies the largest part of the interior cavity corresponding to the opening 18 of the cage.
  • FIG. 3 represents the cage equipped with the screen and used as a terminal of the electrical equipment 20, for connecting a cable 19 of small diameter.
  • the screen occupies a high position since the stripped end 19a of the cable occupies a small part of the volume of the interior cavity of the cage.
  • the risks of connection errors are high, because that it would be easy to accidentally introduce other cables into the opening of the cage.
  • the screen has all its justification and fulfills its function.
  • the screen is a rigid plate produced in one piece, for example by stamping, molding, thermoforming, etc.
  • stamping molding, thermoforming, etc.
  • Other constructions are possible and will be described by way of examples with reference in the following figures.
  • Figures 5 and 6 show a construction in which the screen 16 is made of two elements sliding relative to each other.
  • the screen 16 comprises a first element 16a and a second element 16b.
  • the total height of the screen in the deployed state is h.
  • the height of each element 16a and 16b is substantially h / 2, which corresponds to the height of the screen in the folded state.
  • the deployed position is that which corresponds to the connection of a small diameter cable and the folded position is that which corresponds to the connection of a large diameter cable. All intermediate positions are obviously possible.
  • FIGS. 7 and 8 represent a construction in which the screen 16 is flexible and retractable and can be produced in the form of a flexible sheet or of several lamellas articulated with respect to each other. It is then placed between guide elements 21, 22 which allows it to perform its screen function in the manner of a roller blind.
  • Figure 7 shows such a deployed screen.
  • the screen is partially or completely retracted as shown in Figure 8.
  • the overall height can be greatly reduced, the height of the screen in the retracted state being very small.
  • the screen is attached, which gives the user the choice of whether or not to equip the cage with a screen.
