Description

  • The The invention relates to a plastic injection molding technique manufactured electrical switching element.
  • By DE-PS 23 09 041, the DE 35 43 751 C2 , the DE 40 29 231 A1 and the DE 43 42 966 A1 are designed as key switch electrical switching elements known. In this case, each acts as the actuator button by her in the direction of their longitudinal direction extending in the direction of actuation movement on at least one contact element having a on a particular designed as a printed circuit board flat component bearing area, an elastically formed switching area and a contact area, the is electrically connectable with a present on the flat component counter-contact area. Although these electrical switching elements are relatively simple, but they are so limited in their application to linearly adjustable actuators.
  • Farther is formed by DE-A 43 26 226 a designed as a toggle switch electrical switching element has become known, with a about a support shaft swiveling actuator and with a first and a second each - a clicking sensation - each a projecting contact element associated switching area, the facing each other with respect to the support shaft and by tilting of the actuating element are einknickbar and have contact areas, the counter-contact areas forming a first switch and a second switch opposite one another are arranged, wherein the on and off operation of the first and the second switch upon buckling of each - a clicking feeling causing - projecting Switching ranges done. By the arrangement of the first and the second - one Knack feeling inducing - switching range bridging Function bar between the actuator and the two projecting contact elements when tilting the actuating element in one direction the toolbar in the same direction as the actuator pivoted about the second projecting contact element. As a result this is the first projecting contact element against the toolbar pressed so that the first switch is turned on generating a first click feeling. Will the actuator in the same direction further tipped, the toolbar can be the first protruding contact element not in a position beyond it to press. Thus, the toolbar is in the opposite direction to the Movement direction of the actuating element to pivoted the first protruding contact element. This will the second projecting contact element from the toolbar pressurized, so that the second switch is turned on generating a second click feeling. In this toggle switch so-called safety mats come with it molded elastic contact elements for use within the elastic switching region so-called contact pills as a contact area record and usually with a flat formed in particular of a printed circuit board Component be brought into operative connection, cooperating with it Having opposite contact areas. The individual contact elements come over here the one end of the same forming bearing areas on the circuit board sealing to the plant while the other end of the same about the actuator over connected to the actuator Ansteuerelemente is assigned. This toggle switch stands out by a complicated structure for the realization of the desired switching functions out. The production cost is great here, so that such a component is not inexpensive to manufacture. The safety mats will be in more or less big Dimensions generated and represent separate components, so that with it an increased storage costs accompanied. In case of improper manufacturing, it may be beyond be problematic, optimal positioning of the opposite To realize contact areas of the switching mat and the printed circuit board, so that it after mounting the switching element on the circuit board under circumstances can lead to malfunction.
  • Finally is by the US-PS 5 803 243 again designed as a toggle switch electrical switching element has become known in which the order of a Support shaft swiveling actuator over it firmly connected control elements on individually produced contact elements acting on a particular designed as a printed circuit board flat component come directly to the plant and over their contact area with on the flat component existing counter-contact areas cooperate. Again this is not too complex but also not from one inconsiderable Number of components constructed electrical switching element is limited in its application and also not easy mountable.
  • Of the Invention is based on the object, at least substantially by plastic injection molding developed switching element to the effect that the disadvantages to be overcome by the state of the art, the storage is eliminated and the desired one Switching function optimally executed can be. Furthermore, a reduction of the production costs and a cost reduction guaranteed become.
  • These The object is achieved by the characterizing part of the main claim specified characteristics solved. Advantageous in such a construction of an electrical switching element is that the made of plastic, hinged together components in an injection molding process produced and immediately afterwards with the associated Kontektelement be connected in a further Spitzgußvorgang, i.e. the entire electrical switching element can fall directly ready to be produced.
  • advantageous Further developments of the subject invention are the dependent claims remove.
  • Opposite the usual Safety mat is doing that of a thermoplastic elastomer existing contact element over the molded-on approaches easily fixed, for example in the area of a printed circuit board become. Since no separate component is available, also eliminated the for Safety mats or mats-like elements required storage.
  • The Contact element advantageously has different elasticity executed Areas on, preferably on a circuit board for Plant next contact area less elastic than the between this support area and the contact area arranged elastic Switching range is formed.
  • Of the Subject of the invention is based on an embodiment in the drawing and is described as follows. It shows:
  • 1 An electrical switching element associated with a printed circuit board;
  • 2 The switching element after 1 with components still in the injection molding position;
  • 3 The representation of two interconnected contact elements according to 1 with it by the injection molding integrally formed control elements of the switching element after 1 and 2 ;
  • 4 A spatial representation of the contact element after 1 to 3 in different views;
  • How out 1 shows is on a particular designed as a printed circuit board flat component 21 the electrical switching element according to the invention 13 assembled. Visible are a switching element housing 14 molded thereon, provided for positioning the switching element on the component frame 15 , one over an axis 16 in the switching element housing movably held actuator 17 and over adjustable control elements 9 as well as molded contact elements 1 in open spaces 19 . 20 of the frame are arranged. About in the 3 and 4 specified approaches 6 (not visible here) finds a positioning of the contact elements and thus the switching element 13 on the circuit board 21 instead, so that an exact positioning of the opposite contact areas (not recognizable here) of the switching element associated contact elements 1 on the one hand and on the circuit board 21 existing counter-contact areas (also not visible here) is given.
  • 2 shows the electrical switching element 13 consisting of a switching element housing 14 complete with molded frame 15 , which was produced by injection molding a multi-component thermoplastic. In the switching element housing 14 this was about an axis 16 swiveling actuator 17 introduced by injection molding of a thermoplastic material in such a way that a virtually play-free articulation in the region of the switching element housing 14 given is. On the switching element housing 14 are, as already in 1 described, control elements 9 articulated molded, each a contact element 1 wear. In this example, no contact pills, as in 4 recognizable, provided; rather, the contact area 18 Made of a conductive plastic, which has the same effect as the existing example of carbon contact pill 8th according to 4 having. The conductivity can be generated, for example, using a known MID method. For the purpose of assembly, the control elements 9 pivoted by 180 ° in their operative position and find in the open spaces 19 to 20 of the frame 15 their recording.
