Definitions

  • the invention relates to a magnetically actuated contacting device, in which contacts such as signal or switching contacts in the form of contact heads and counter-contacts can be closed by triggering by means of magnetic force.
  • an electromechanical connecting device is known from DE 296 10 996.
  • Two parts of the connecting device which basically correspond to the functions of the plug and plug coupling, can be placed against one another in different positions. However, only in a certain position do they fit together in the intended manner due to mechanical coding.
  • a magnetic coding by means of magnets positioned differently and with different poles can only be used to close several contacts in this suitable position.
  • the possible use is limited to the establishment of a single connection according to a single specific pattern.
  • the invention has for its object to provide an initially mentioned contacting device with which the disadvantages of the prior art can be avoided and in particular a contacting device for a variety of switching or connection functions can be created with the aim that in the area of the contacts despite the movement required to make the contacts, there is no friction and no grinding.
  • This object is achieved by a contacting device with the features of claim 1.
  • Advantageous and preferred embodiments of the invention are the subject of the further claims and are explained in more detail below. The wording of the claims is made the content of the description by express reference.
  • the contacting device has several elongated contact arms. These are fastened at one end and have closed contacts or a corresponding electrical lead there. At another end they have a magnetic area and a contact head. This end is movable against a mating contact assigned to each contact arm.
  • a trigger magnet is provided which is movable relative to the contact arms and counter-contacts, so that the relative movement of contact arms and counter-contacts on one side is important here relative to the trigger magnet on the other side. In an active position, the tripping magnet attracts the magnetic area of the contact arm and brings the contact head against the mating contact.
  • the contact head and counter contact are separated, since the magnetic attraction force is absent. It is particularly important for the invention that the relative movement between contact arms and counter-contacts on one side and the release magnet on the other side takes place in a surface or in a plane which is essentially perpendicular to the direction of movement of the contact heads.
  • the relative movement can be a linear displacement or a rotary movement, with a rotary movement being preferred.
  • the contacting device is and remains a structural unit, that is, it does not have to be structurally changed for operation. It is only activated by turning or pushing.
  • a slide or rotor can be moved by means of a linear or rotary movement.
  • one or more electrical contacts are closed between a contact head on a contact arm and an associated mating contact, for example in order to trigger certain signals which are assigned to the given position.
  • a restoring force can be provided which, in addition to the lack of magnetic attraction force, separates the contacts in a deactivated position.
  • a spring force can be provided in the contact arms, which causes the contacts to separate and the contact arms to be reset.
  • there should be a separation distance which differs depending on the type of voltage applied, advantageously being several millimeters.
  • a contact arm can consist of thin or flexible metal. It is advantageously made in one piece and, for example, as a metal strip. Materials such as resilient copper sheet or the like can be used.
  • a plurality of contact arms can be provided which are connected in one piece or are connected to one another. In particular, they are electrically connected to one another, for example, all on a signal transmitter, which then generates a signal that can be picked up at the different mating contacts.
  • the contact arms can be made in one piece from be worked out piece of material, for example from a flat sheet.
  • the closed contacts or the attachment points of several, in particular all, contact arms can lie in one plane. This should be parallel to the plane of the relative movement or the plane of movement of the trigger magnet. If the mating contacts lie in a plane parallel to this, the distance to be covered is the same for the contact arms. Depending on the design of the contact arms, they can be of the same length, and designs of different lengths are also possible, in particular in order to design a contacting device in a space-saving and space-saving manner.
  • the assignment between a contact head or contact arm and a mating contact is advantageously determined such that the same and only this contact head is in contact with the assigned mating contact.
  • the contact arms and the mating contacts are arranged in a fixed and defined manner on a contacting device, in particular a carrier or housing thereof.
  • the trigger magnet can be moved.
  • it can be arranged on a rotor for a rotary movement.
  • the rotor can be provided with an axis of rotation, to which a manual handle, for example a rotary toggle, can be coupled or attached. It can be a slide for a sliding or linear movement.
  • a rotor or slide can be made of plastic, for example, and the trigger magnets are attached to it, for example embedded. It is possible to inject the release magnets into the rotor in order to create a captive and unchangeable arrangement.
  • a single trigger magnet can be provided. On the path of its relative movement to the contact arms, it can pass through these and in different different active positions bring a contact arm with the contact head against an assigned counter contact.
  • a plurality of trigger magnets are provided. These are advantageously provided next to one another or in the radial direction at a distance from one another, the distances advantageously being the same or being able to lie in a certain grid.
  • a plurality of release magnets can also be provided in the circumferential direction, with angular distances advantageously being the same or lying in a specific grid.
  • the arrangement can be such that in an active position there is a counter contact between the release magnet and the contact head or contact arm.
  • the trigger magnet pulls the contact head towards you and thus against the mating contact.
  • Contact heads or counter-contacts can be arranged in groups which, during a rotary movement with a rotor, lie on a line through the axis of rotation or on a line which runs vertically to the direction of movement. These groups also advantageously have the same angular spacing or are advantageously arranged in a grid.
  • This can be, for example, in the form of a film with an applied or printed conductive coating.
  • the counter contacts are essentially electrically separated from one another and have connections which extend to the outside and can be contacted by means of plug connections or the like. Interconnection of mating contacts can thus advantageously take place via the external connections, which makes the application more universal.
  • FIG. 1 shows a side section through a code switch in which the invention is implemented
  • FIG. 2 is a plan view of the part of FIG. 1 with the contact arms
  • FIG. 3 shows a plan view of the rotor from FIG. 1 with the release magnets
  • the code switch 11 in FIG. 1 has a housing 13 in which a round rotor 15 with an axis of rotation 16 is rotatably mounted.
  • the axis of rotation 16 is mounted on a pivot bearing 17.
  • trigger magnets 19, which are shown in black are provided in a distribution grid.
  • Other places in the distribution grid, at which trigger magnets can also be provided in alternative designs, are merely represented by circles, but not here. Openings can also be provided here, into which 15 additional trigger magnets 19 can be placed if a rotor is individually constructed.
  • the rows of three shown can be distributed in the same way over the entire rotor 15 about the axis of rotation 16 with the direction of rotation shown.
  • a partition 21 is located in the housing 13 below the rotor 15.
  • a mating contact 23 is provided, which protrudes downward from the partition 21. It is provided with symbolically shown contacts that lead to the outside.
  • So-called contact combs 25 are provided in the space between partition 21 and housing base 14, see also FIG. 2. These have contact arms 27 projecting from a common base 26. At the end of contact heads 28 are attached. Either the contact heads 28 or the associated areas of the contact arms 27 are magnetic.
  • the contact combs 25 are mechanically attached to the housing base 14. Due to the flexibility upwards due to the very low material thickness, the contact arms 27 can be moved upwards. This is shown by the movement arrow with the two directions. They come to a stop at the opposite mating contacts 23, which are arranged on the partition 21 in a fixed position. On the outside, the contact combs 25 are provided with electrical connections, as symbolically shown in FIG. 1. As can be seen from the comparison of FIGS.
  • the grid of the arrangement of the release magnets 19 according to FIG. 3 corresponds to the placement of the contact heads 28 on the contact arms 27 according to FIG. 2. If the rotor 15 according to FIG 3 now brought via the code switch 11 according to FIG. 2, for example in the illustrated correspondence the trigger magnet 19 arranged radially on the inside would pull the radially inside contact arm 27 with the associated contact head 28 upwards, ie towards itself. The contact head 28 comes to bear on the associated mating contact 23. This is how an electrical contact is made, similar to a relay. The remaining contact arms 27 remain in a straight shape on the housing base 14 due to their pre-bending.
  • the middle grouping of release magnets 19 lies exactly above the contact comb 25 or the mating contacts 23 and contact heads 28. Because on the two radially inner ones If release magnets 19 are provided, the two radially inner contact arms 27 are pulled upward, so that the contact heads 28 attached to them abut the counter contacts 23. If the rotor 15 is rotated further by 45 °, all of the contact arms 27 are first pressed down again by their own spring force and all contacts are released. If the third group with the individual trigger magnet arranged radially on the outside lies above the counter contacts 23, only the radially external contact arm 27 with the contact head 28 is pulled upward. In this way, the contact is closed again, but against the radially outward counter contact 23.
  • FIG. 2 Instead of the one contact comb 25 according to FIG. 2, several contact combs, possibly with different designs, or only individual contact arms 27 can be provided. For example, a further contact comb can be provided in FIG. 2 opposite the axis of rotation 16.
  • contact arms 127 are of different lengths, but they extend from the common base 126 in only one direction.
  • contact arms 227 of different lengths go away from the common base 226 in both directions.
  • a slide switch with a straight or curved link can also be produced in a corresponding manner.
  • a slide can have release magnets similar to those from FIG. 3 distributed in any grid along the sliding direction in a grid.
  • One or more groups of contact arms can be provided along the sliding track, for example also as contiguous contact combs according to FIG. 2. In certain sliding positions, those contact arms or contact heads are raised and brought against counter-contacts, above which release magnets are located.
