Definitions

  • a constructionally relatively simple and advantageous embodiment of the bistable relay according to the invention is one in which the respective contacts are fitted in a fixed manner on the associated arm.
  • a construction can also be provided in which, for example, the movable contact is mounted in a separately movable manner and is activated via the movable arm.
  • litzwire To make electrical contact to the contact connecting point of the movable arm, use can be made, for example, of litzwire or, according to yet a further embodiment of the invention, a sliding contact transmission can be provided as a result of which the necessary welding and/or soldering operations for joining the litzwire are avoided.
  • An embodiment of the invention which is suitable, inter alia, for this purpose is one in which the spring means consist of a first leaf spring which extends in the longitudinal direction of the movable arm and of which one end is coupled in a fixed manner to the movable arm and of which the other end is coupled to the drive means, the end coupled to the drive means being held at a predetermined greater spacing from the movable arm than the end coupled to the movable arm, and the contacts being arranged such that they can be set to the first (closed position) by moving the end, coupled to the drive means, of the first leaf spring away from the movable arm.
  • the operating means act preferably on the end of the first leaf spring coupled to the drive means.
  • an L-shaped operating arm of electrically insulating material coupled to the first leaf spring is provided in yet a further embodiment of the invention with a limb extending perpendicularly to the leaf spring as operating handle.
  • the support body is made of plastic and has an essentially M-shaped section provided with a widened central section or base part for mounting the signal terminals thereon, the base part being provided, in the plane of the M-shaped section, with at least one upright wall extending outside the periphery of the support body, which wall is rounded off laterally in the direction of the base part at the end remote from the base part, the housing of the switching module being provided with an essentially rectangular compartment having a length, width and depth for the reception of the support body, the length being chosen such that the support body can be slid in the direction perpendicular to the plane of the M-shaped section, the width being less than the dimensions of the support body in the plane of the M-shaped section parallel to the base part, with a depth essentially equal to the dimensions of the support body in the plane of the M-shaped section perpendicular to the base part, and with an opening through which the signal terminals can extend outside the housing.
  • the support body is made of a thermoplastic, such as for example
  • Figure 2 shows diagrammatically the rear view of the bistable relay in Figure 1.
  • the first leaf spring 5 is firmly joined thereto, for example by means of soldering or a so-called compression joint.
  • the other end of the first leaf spring 5 is coupled to the armature 10 of the drive means 9.
  • this end of the first leaf spring 5 is kept at a greater distance from the movable arm 4 than the end of the first leaf spring 5 attached to the arm 4. This produces a static pretensioning of the first leaf spring 5.
  • this pretension, or contact force has to be overcome.
  • the embodiment of the drive means 9 which has been shown and described is compact in construction and, as a result of constructing the first yoke 21 from separate parts 26, 27, tolerances in the dimensions of the other components of the magnetic system can be effectively absorbed.
  • Figure 3 shows a section along the line III-III of the long limb 3 of the housing 2.
  • This essentially S-shaped section achieves a long path, which is sufficient in accordance with specification, for creepage currents between the two arms 4, 11 while maintaining a closely adjacent, electrically insulated mounting of the two arms in order to achieve an as large as possible mutual magnetic influence (Lorentz effect).
  • Figure 6 shows a switching module provided with a bistable relay in the embodiment according to Figure 1.
  • the switching module 40 comprises a plastic housing provided with connecting devices 41 and a switching element consisting of a lever 42 and a leaf spring 43 coupled thereto.
  • Said leaf spring 43 can be tensioned by means of a pawl 44, which acts on the connecting point of the lever 42 and the leaf spring 43, and on an operating key 45 coupled thereto.
  • Mounted at the other end of the leaf spring 43 is a movable contact 46 which can be brought into contact with an immovably mounted contact 47. As a result of the tensioning of the leaf spring 43, the contacts 46, 47 are pressed against one another and locked in this position by the pawl 44.
  • An electrical circuit connected between the terminals 51 and 52 can now be switched off both via the bistable relay and the contacts 46, 47.
  • An electrical circuit connected between the terminals 51 and 53 can only be interrupted via the contacts 46, 47 of the switching element. If such a switching module is used in an installation box such as that described in said European Patent Application 0,345,851, one or more group connecting points of an electrical installation can be remotely switched by means of the bistable relay 1 from the energy distribution point in an electrical installation.
  • Separate control signal terminals 60 are provided for energising the drive means 9 of the bistable relay 1.
  • the signal terminals 60 are constructed as a so-called edge connector for making contact with a printed circuit board 64 via which the control signals for the bistable relays are supplied.
  • Figure 8 shows a bistable relay constructed as a separate module 80 for use in a housing of a switching module, for example the switching module shown in Figure 6.
