Definitions

  • the invention is based on an electromagnetic switch according to the preamble of the main claim. It is already known in such a switch to provide the main current contacts with inclined flat contact surfaces and the contact bridge with correspondingly bent ends as contact sections. When the contacts are closed, the contact bridge and main current contacts should then lie against one another over a relatively large area.
  • a disadvantage of this arrangement is that the contact bridge, which is rectangular in plan view, requires an anti-rotation device, since otherwise no parallel contact is possible.
  • Such an anti-rotation device is known, for example, in the form of ribs or walls in the cap carrying the main current contacts, which surrounds the switch room.
  • the invention has for its object to provide an electromagnetic switch, especially for starting devices for internal combustion engines, the main current contacts and contact bridge are designed such that the disadvantages of the known solutions are avoided and thereby the life of the contact parts with increased demands on their performance and a greater security against welding of the contact parts can be achieved.
  • the object is achieved by the subject matter of claim 1.
  • the advantage here is that with higher contact force, reduced bounce and good self-cleaning effect due to the shape of the Contact surfaces is made possible in an economical manner, even in the event of dimensional deviations, to always make contact at almost the same point on the contact surfaces, thereby ensuring reliable contact and good heat dissipation without contact welding.
  • Another advantage is that the round contact bridge no longer requires lateral guidance, which also contributes to increasing the service life of the switch.
  • the measures listed in the subclaims allow advantageous developments of the electromagnetic switch specified in the main claim. It is particularly advantageous that the main current contacts are designed as screws with a polygonal head, so that no security against rotation is required, since they can be fixed in their position in the cap in a simple manner. In addition, the lifespan of the main power contacts is increased by multiple use of the main power contacts due to the large number of molded contact surfaces. With an angle of inclination of the contact surfaces to the direction of the switching movement of 45 °, the most favorable ratio between contact force, tendency to bounce and self-cleaning is made possible.
  • the main current contacts can be used economically not only from expensive copper but also from steel with a contact section made of copper.
  • manufacturing tolerances can be compensated for by the spherical segment-shaped contact surface of the contact bridge in such a way that the contact bridge always lies almost at the same point on the contact surface of the main current contacts.
  • the also spherical section-shaped back of the contact bridge and the somewhat conical shape of the bearing point between the contact bridge and the contact bridge support can even compensate for dimensional deviations.
  • FIG. 1 shows an electromagnetic switch in longitudinal section
  • FIG. 2 shows a section through the switch along the line II-II in FIG. 1
  • FIG. 3 shows the switch in partial section with a modified contact bridge

  • the switching pin 26 together with the guide sleeve 29 and the contact bridge carrier 32 arranged on it are moved with the contact bridge 33 by the magnet armature 21. During this movement, the switching pin 26 is pushed further into the switching space 8, so that the contact bridge 33 is pressed with its contact surface 39 onto the associated contact surfaces 17 of the main current contacts 13 and 14 and is held on the main current contacts 13 and 14 with the aid of the force of the contact pressure spring 31 .

During this movement, the switching pin 26 takes the contact bridge 33 with it and separates it from the main current contacts 13 and 14, so that the movable switching parts 21 to 39 again assume their rest or starting position shown in FIG.
  • the contact surface 39 of the round contact bridge 33 which is provided with the shape of a spherical cap section, and the rounded contact surfaces 17 of the main current contacts 13 and 14 are designed such that, when new, the contact contact in the first third of the main current contacts 13 and 14 facing contact surface 39 of the contact bridge 33. Good heat dissipation from the contact points is achieved. No rotation lock is required for the round contact bridge 33. Shaking influences can cause the contact bridge 33 on the contact bridge support 32 to be rotated about the longitudinal axis 40 of the switch. As a result, other essentially punctiform points of the contact surface 39 come into contact with the contact surfaces 17 of the main current contacts 13 and 14 but never the edges. The main current contacts 13 and 14 can be used several times.
  • the main current contacts 13 and 14 are rotated so far about their longitudinal axis into the recess 18 and / or between the ribs 19 of the cap 9 that the contact surface of the contact bridge 33 can rest on another contact surface 17 .
  • the bouncing effect is reduced by the contact surfaces 17 and 39 arranged inclined to the switching direction. In addition, this increases the contact force and the self-cleaning effect of the contact surfaces. The lifespan and performance of the electromagnetic switch are thus increased.
  • the electromagnetic switch shown in Figure 3 has a modified contact bridge 41. As far as the other parts are the same as those of the embodiment of Figures 1 and 2, they have the same reference numerals.

  • the rear side 44 of the contact bridge 41 is also designed as a flattened spherical cap with a radius of curvature that is substantially greater than that of the contact surface 39.
  • the contact bridge 41 can thus somewhat compensate for dimensional deviations which are inclined against the longitudinal axis 40 of the switch, for example as a result of manufacturing tolerances. As a result, the contact surfaces of the contact surfaces 39 and 17 of the contact bridge 41 or of the main current contacts 13 and 14 are always in the desired location.
  • the bearing bore 45 of the contact bridge 41 can also be somewhat conical in the case of a cylindrical bearing shoulder 43.
  • the first exemplary embodiment of the main current contacts 13 and 14 according to FIGS. 1 to 3 has contact surfaces 17 which are formed as fillets in the form of conical jacket sections or cylindrical jacket sections which extend over the entire trapezoidal surfaces of the contact section.
  • FIGS. 4 and 5 show a second exemplary embodiment for main current contacts.
  • a main current contact 46 in turn has a hexagonal head 47 which is provided with a contact section 48 which is inclined at 45 ° to the longitudinal axis and thus to the switching direction.
  • the six trapezoidal partial surfaces of the contact section 48 are each provided with a cylindrical jacket-shaped fillet as contact surfaces 49, which extends over the central part of the trapezoidal partial surfaces.
  • the main current contact 46 made of an electrically highly conductive material such as copper, a modification for the material used is indicated in dash-dotted lines in FIGS. 4 and 5.
  • the main current contact 46 is formed with connecting bolts and head 47, for example made of steel.
  • At the front of the head 47 is a Bearing approach 50 molded.
  • the contact section 48 is formed from copper and is provided with the cylinder jacket section-shaped contact surfaces 49 and with a longitudinal bore 51. The contact section 48 is pushed onto the bearing projection 50.

  • the corresponding, correspondingly large main current contacts can be produced economically, which is particularly necessary for large-scale production.
  • a contact section as shown in a third exemplary embodiment of a main current contact 53 according to FIGS. 6 and 7 is suitable.
  • the head 54 of the main current contact 53 is again designed as a hexagon.
  • the contact section 55 is only inclined on two sides with respect to the switching direction. These sides are rounded out as contact surfaces 56.
  • the wear on the main current contacts 57 is lower with the particularly favorable heat dissipation from the contact contact point. Therefore, two contact surfaces 56 per main current contact 53 are sufficient for the service life of the switching device. The higher copper requirement and thus the higher price therefore justify the use of this embodiment example for special designs of electromagnetic switches.

Abstract

Un commutateur électromagnétique, en particulier pour appareils de démarrage de moteurs à combustion interne, comprend des contacts de courant principal (13, 14) dont les surfaces de contact tournées vers l'axe longitudinal (40) du commutateur présentent des protubérances arrondies (17). Le commutateur comprend également un contact arrondi rotatif à pont (33) ayant une surface de contact (39) qui fait partie d'une calotte arrondie dont le rayon de courbure est inférieur à celui des surfaces arrondies (17) des contacts de courant principal (13, 14). Cette conception des parties de contact (13, 14; 33) diminue la tendance du commutateur à rebondir et à se souder lors de hautes performances, tout en améliorant sa capacité à dissiper la chaleur, étant donné que le contact essentiellement ponctuel se fait toujours lorsque le contact à pont (33) et les contacts de courant principal (13, 14) sont dans la position voulue, grâce entre autres à la possibilité de compenser des variations dimensionnelles.
