Definitions
- the invention relates to a thermal overload relay according to the preamble of the claim 1.
- control wiring is in shape is realized by conductor tracks on the board.
- overload relays known for protecting three-phase motors are also on the market Connection technology for cables in the form of screw terminals or screwless ones Cage clamp terminals are offered, which is why the overload relays are integrated in a controller mounted on a board, additional electrical connections assumes.
- the object of the invention is to provide a thermal overload relay of the type mentioned To create a way in which the assembly technology is considerably simplified.
- pins are arranged on one side of the housing, which protrude from the housing protrude and connected to the components located inside the housing are; with these pins the housing, and thus the one in the housing thermal overload relay soldered onto a circuit board.
- the overload protection function can be implemented electronically; bimetal elements can also be used or elements of a shape memory alloy can be provided with which the overload protection function is implemented mechanically.
- a load 10 which can be a motor, for example, is connected via power lines 11 Three-phase supply.
- a motor contactor 12 for one and one Switch off and thus to control the motor, which is normal and usual Contactor is trained.
- This contactor is controlled by a controller 13.
- an overload relay 14 which, for example an electronic overload relay or a mechanical overload relay with May be bimetallic and that in the event of an overload within the network conductor, d. H.
- the overload relay 14 can be reset by means of the controller 13 after a shutdown be by a line 16, either electronically or mechanically Signal for resetting the overload relay 14 is transmitted. Over a dashed Line of action 17, the overload relay 14 can also be reset manually, for example by means of a push button, and over the further dashed line of action 18 the status of the overload relay 14 can be reported to a center.
- the line of action from the controller 13 to the motor contactor 12 is designated by the reference number 19. These lines of action 15, 16 and 19 can be electrical or mechanical signals transfer.
- FIG. 2 shows the overload relay 14 as it can be designed according to the invention.
- This overload relay 14 is located in a cuboid housing 20, the a page 21 is a user interface, the setting elements 22 and 23 in the form of Knobs or elements that can be rotated using tools, as well as imprints having.
- solder pins 24 are arranged, which in corresponding Openings 25 inserted on a circuit board 26 and with on the circuit board 26 located conductor tracks 27 can be soldered.
- the conductor tracks 27 are open indicated the side of the circuit board 26 which is facing the housing 20; indeed are the conductor tracks 27 on the opposite side, since they are there are easier to solder.
