Definitions

  • the invention relates to an electrical switch with an elastically deformable contactor, which can be moved against a spring force from a basic position to a switching position, wherein a connection of the contactor changes from a first to a second selective contact body.
  • a switch of this kind is used for example in EP 0 837 483 A2 mentioned as prior art and is shown in Fig. 24 of the document.
  • a common contact body for both switching states, an elastically deformable contactor, an actuating element, a first and a second selective contact body and a lever is arranged in a housing in a housing.
  • the elastically deformable contactor has a substantially elongated pull tab and a curved portion arranged in parallel to the pull tab in plan view.
  • the contactor further comprises an area connecting the pull tab and the arched area, which has a contact point arranged on both sides of the curvature.
  • Switches of this type are executed, inter alia, in the miniature or subminiatur Symposium and serve switching tasks in which a normally closed electrical contact is temporarily interrupted by mechanical action on the actuator or a connection to a second contact is made, which for the time in which the actuator in the switching position is maintained.
  • the actuating element or the contactor can also be locked.
  • Switches of this type are particularly suitable for tasks of position detection in automatic processes.
  • typical application areas can also be locking systems, body and interior areas of a vehicle as well as various position queries in household appliances or other mechanisms.
  • the relative movement in the switch is achieved by a longitudinal expansion of a divided into two areas central spring / switching spring.
  • a rigid region of the switching spring is moved in the longitudinal direction of the switch via an angle, which in turn is deflected by an actuating spring.
  • this elongation of the switching spring of the lower meandering part of the switching spring is elastically deformed This happens in that the actuating spring is deflected by the common attachment point with the switching spring in the housing, wherein the switching spring is limited in their freedom of movement by the two contacts.
  • Auslegeschrift 1 168 993 also deals with an electric snap-action switch with the aim of making the friction and rolling movements of the contact pieces stronger.
  • a rigid contact arm which is articulated at its end facing away from the contact points, reciprocated by a switching arm between two terminals.
  • the switching arm is in turn deflected by an actuating element at one end.
  • the other end of the switching arm is articulated to a common terminal.
  • a C-spring To support a first contact in the basic position of the switch is a C-spring, which is more overarched upon actuation of the actuator.
  • the overall articulation of the rigid contact arm and the circular deflection of the switching arm effect only very small linear movements of the contact point of the rigid contact arm on the contact point of the terminal. Again, there is no linear movement of the contact point of the contact on the contact surface of the terminal instead.
  • the compression spring tongue is arched, at the same time the leaf spring area (without experiencing a deformation ) is guided by the actuator in the direction of the switching point. After passing the switching point, the switching spring snaps from the upper contact to the lower contact.
  • the end portion After passing the switching point, i. After the pull tab has passed the support point of the curved portion, the end portion changes from the first contact point to the second contact point. This is done in an approximately linear, directed perpendicular to the pull tab movement or by a substantially parallel displacement of the contactor in the direction of actuation of the actuating element.
  • the second contact point of the contactor After switching the second contact point of the contactor completes another arcuate movement with further movement of the pull tab, wherein the second contact point rolls on its support point in the same direction as the arcuate movement of the pull tab. It therefore comes on the second contact point to a greatly reduced linear motion or to a greatly reduced sliding or rubbing of the contact point on the contact surface in the longitudinal direction of the switch. Under certain geometric conditions, the linear movement of the contact points on the contact surfaces goes to zero.
  • the second contact point in the known switch determines the switchable by the electrical switch load.
  • US 3,548,132 describes a miniature precision snap-action switch which has a one-piece elastically deformable contactor.
  • the contactor is bent at an end portion substantially at 180 °, with its end is firmly received on a common contact.
  • the substantially parallel to the folded area extending leaf spring area has a built-in freed Kochbung which presses in interaction with the folded area a contact against a first selector switch. By squeezing the folded area over an actuating element snaps after sweeping a dead center of the contact from first selector switch to a second selector switch.
  • the leaf spring can be elastically deformed due to the contact of the contact on the second selection contact body by further Hineinbelie of the actuating element within the switch housing, since the contact is pressed with respect to the actuating force on an abutment.
  • the elastic deformation of the leaf spring region causes a movement of the contact directed perpendicular to the actuating force on the contact surface, which is possible only on the second contact surface. Since the geometric conditions do not permit such a deformation of the leaf spring at the first contact point, the current which can be switched via the first contact point limits the currents which can be switched with the switch.
  • US 3,578,926 describes an electrical switch with a canted, elastically deformable contactor according to the preamble of claim 1.
  • the object of the invention is to provide an electrical switch with a spring mechanism in which a sufficient linear movement takes place both on a first contact surface and on a second contact surface and thus the disadvantages of the prior art are avoided. It should be ensured a simple structure, ease of manufacture and easy installation and reliable operation with a long life.
  • the elastically deformable contactor of the switch according to the invention is so movable as in the prior art that the contactor with the contact points is alternately with two contact surfaces of elective contact bodies in conductive or non-conductive connection.
  • the pull tab In the longitudinal direction of the switch while the Hauptausdehnungsraum the pull tab is referred to in the normal position of the switch. Regardless of the mounting position of the switch according to the invention, this direction should also be referred to as the horizontal direction of the switch.
  • the vertical direction of the switch is defined by the distance between the two contact surfaces, where "top” refers to the side of the contactor in which the actuator is in the home position.
  • the contactor is configured so that it has two curved areas spaced from each other, between which a pull tab formed in such a way that it is without the angle between the arched area and end to change range, is elastically deformable.
  • the two arched areas are substantially parallel to the flexible pull tab.
  • the end region of the contactor connects on one side or at one end the two curved regions and one end of the pull tab.
  • the contactor thus has an approximately fork-like appearance in plan view, which has at least two projections or prongs.
  • At least one extension is designed as a pull tab and an extension as a curved portion.
  • the end of the arched area is based in the installed state on the necessary for both switching states for the passage of an electrical signal common contact body from the end of the pull tab is attached to an end portion of the rotatably mounted lever. If the rotatably mounted lever is deflected by the actuating element, essentially only the pull tab deforms, the deformation remaining in the elastic range.
  • the attachment point of the pull tab on the end portion of the lever simultaneously describes an arcuate movement by the forced arcuate movement of the attachment point or the connection point between pull tab and lever and the simultaneous support of the end portion via the contact points on the contact surfaces is achieved that generates a force in the longitudinal direction of the switch becomes, which moves the contact point on the contact surface linearly approximately horizontally. Due to the relative to the pull tab relatively rigid connection of the curved portion of the contactor to the end portion of the contactor, an angle in the transition region between the curved portion and the end portion is not changed during deflection of the lever.
  • a curved region is provided on the contactor, which is arranged centrally in plan view between two webs of the pull tab.
  • the curved area is designed so stable that there is no change in angle between the curved area and the end area upon deformation of the lateral Werlaschen Kunststoffe.
  • the free end of the arched area is in turn supported on the common contact body and the two Werlaschen Kunststoffe are at the end, which faces away from the end portion, connected to each other and attached to the lever in a deflection of the lever or the connection point of the Pull tab on the lever substantially only the pull tab or the pull tab areas, which are arranged laterally adjacent to the curved area, deformed ..
  • the curvature of the curved area Simultaneously with the deformation of the pull tab is the curvature of the curved area
  • the angle which is strictly mathematically spanned by a tangent to the curved portion at the crease line between curved portion and end portion and the end portion, during the movement of the connection point of the pull tab is not changed substantially.
  • the inventively enforced linear movements of the contact points on the contact surfaces both on the first selection contact body and on the second selection contact body is achieved that disturbing foreign layers are mechanically eliminated.
  • the frictional movement of the contact points on the contact surfaces is also important if the switch must be operated under adverse environmental conditions and occur, for example, oxide layers, silicate layers or other undesirable deposits on the contact surfaces. Due to the simple design of the contactor according to the invention can thus be achieved that a self-cleaning of the contact surfaces and the contact points in the electrical switch with spring mechanism according to the invention. Due to the friction movements on both contact surfaces, a welding of the contact points is counteracted with the contact surfaces. This has the consequence that with the switch according to the invention larger loads than with the switch according to the prior art can be switched with equally trained contact spring / contactor.
  • the embodiment of the switch according to the invention is not limited to embodiments, as they are known for example from the above-mentioned prior art, but is essential to the invention, in contrast, a rigid connection of the curved Area of the contactor to the end of the contactor and a flexible connection of the pull tab to the end, ie a slightly deformable in the elastic region designed tension spring.
  • the tension spring moves the end portion of the contactor substantially linear and parallel to the contact surfaces of the selector contact body with simultaneous elastic over-buckling of the curved portion of the contactor.
  • a pivot point of the lever which is deflected by the actuating element, is arranged in the longitudinal direction in front of or behind the contact region of the contact point and the contact surfaces.
  • the contact area of the switch between the attachment point of the pull tab on the lever and the pivot point of the lever is arranged.
  • the actuating element is moved in a linear direction perpendicular to the contact surfaces of the selector contact body and thereby deflects the lever so that the connection point at the non-rotatably mounted end of the lever describes a circular motion.
  • This circular movement is counteracted by the support of the points of contact of the contact points on the contact surfaces via the pull tab into a linear movement of the points of contact of the contact surfaces on the contact surfaces.
  • the rotation of the lever can also be effected by a rotational movement of the actuating element with a suitable arrangement of the actuating element. It is conceivable, for example, that an actuating element forms an extension of the pull tab or of the lever.
  • the actuating element is brought by pressing from a basic position to a switching position in which the second contact point touches the second contact surface.
  • the contactor and the actuator due to the elastic tension within the pull tab and the curved portion brought back into the basic position by the lever, which is in contact with the actuating element.
  • the actuating element can also be locked in the switching position in order, for example, to be brought back into the basic position upon repeated actuation of the actuating element by the elastic partial relaxation of the contactor.
  • the convex side of the curved portion of the elastically deformable contactor on the actuating element ie upwards.
  • the support point of the curved region is chosen so that it is supported on the common contact body on the side of the flexible pull tab on which the curvature is not.
  • the supporting point of the curved portion is arranged on the common contact body at a distance from the flexible pull tab, so that the spring force of the biased mounted curved portion generates a torque in the basic position of the contactor and so the first contact point at the end portion of the contactor with a first contact surface the first selector contactor is biased in communication and the actuator remains in its initial position.
  • the first contact location Upon deflection of the lever to which the pull tab is attached to a point where the vertical distance between the flexible pull tab and the support point of the arched portion to the common contact body becomes zero, the first contact location remains in communication with the first contact surface.
  • the switching point is reached, since at this point the torque which presses the first contact point on the first contact point, because of the lack of lever arm is also zero.
  • the switching point or the switching time is reached half way of the actuating element from the basic position to the switching position.
  • such a configuration is not mandatory.
  • the end portion of the contactor is pulled by the pull tab on the second contact surface.
  • the end region describes a nearly linear, substantially vertical movement and the second contact point is in communication with the second contact surface.
  • the force exerted on the actuator deforms the flexible pull tab, forcing it on a curved path.
  • the arched area is elastically arched over by the arcuate movement of the pull tab.
  • the second contact point is in communication with the second contact surface is achieved by the almost invariability of the angle between the arched portion and end portion that the end portion and the pull tab is not in a plane lie. Due to the relatively rigid connection between the arched region and the end region to which the pull tab is also attached, and the forced arcuate path, the end region is moved approximately parallel to the contact surfaces in the direction of the connection point of the pull tab with the lever. In this case, the second contact point is supported with its support point on the contact surface, so that the movement component perpendicular to the contact surface of the end portion can not be performed, and the contact force can act in this direction.
  • the contactor is arranged in the receptacle, that its curved portion is arranged on the same side of the pull tab as the actuating element.
  • an inverted arrangement of the contactor ie with the curved area on the other side, d. h under the pull tab possible, with a suitable choice of the support point of the curved portion of the common Contact body, the basic position and the switching position are interchanged with each other over the above-described embodiment.

Due to the much stronger design of the curved portion 16 relative to the pull tab 14, the torque released by it pushes the support point 34 further against the first contact surface 22, while the pull tab 14 is forced into the arcuate path until the pull tab 14 reaches the support point 36.
