Definitions

  • the invention relates to a contact spring for producing an electrical contact with a contact surface and / or a contact blade, wherein the contact spring has at least two contact points.
  • contact springs are usually used. These are in modern plug-in systems usually narrow, elongated metal elements, which are arranged within a socket, such as an Ethernet connector. As a rule, a plurality of these contact springs are arranged in parallel in order to allow good contact with the plug to be inserted. On the connector side, a contact surface opposite the contact springs is then attached correspondingly. In general, such contact springs have special places where the contact between the contact spring and the opposite contact surface or the corresponding contact blade is to be formed.
  • the object of the present invention is therefore to further optimize the already known contact elements.
  • a contact spring which at different points special contact points has, can make an improved contact.
  • the contact points on the contact spring are mounted so that they each have different spring travel. That is, the spring geometry is designed so that is contacted at different points of the spring parallel to the contact blade or the contact surface contact as soon as a plug is inserted into the socket.
  • the different spring travel from the attachment point or the origin of the contact spring to the arranged on the contact spring contact points ensure that the contact points behave differently at different frequencies.
  • the two contact points have different resonance frequencies, so that at least one of the contact points remains in contact with the contact surface during a vibration, as a rule.
  • the contact spring can in this case, as shown in the first embodiment, be formed as a continuous contact spring, which has arranged at different distances from its attachment successively arranged contact points for contacting the contact surface. In this case, between the individual contact points in each case a region in which the contact spring receives no contact with the contact surface to be contacted. In this case, a plurality of such contact points can be arranged one behind the other on the contact spring.
  • a further exemplary embodiment is characterized in that the contact spring, starting from its origin, has two limbs which each have a different length and which each have a contact point at their limb end.
  • the different length of the two contact spring legs different resonance characteristics of the two contact points, so that when vibration each one of the two contact points remains on the contact surface.
  • a set of springs designed in this way is, for example, mounted in parallel in a contact socket, as is also the subject of the invention, so that the inserted plug is contacted in many places via the corresponding contact springs.
  • FIG. 1 shows a contact blade 2, which is contacted via a contact spring 1.
  • the contact spring has two legs, which make contact with the contact blade via the contact points 3.
  • the two legs are geometrically uniform, so that they have a uniform behavior when shaken. Both legs would start to vibrate at the same frequency and accordingly the points of contact would lose contact with the contact blade 2.
  • FIG. 2 shows a socket 4 of a plug-in system.
  • a contact spring 1 is arranged, which has a contact point 3, which contacts a contact surface 3b of a plug.
  • the spring is mounted within the sleeve 4 on an abutment 6 and has an origin 7.
  • the contact spring 1 has a contact point 3, which is indeed formed over a longer path of the spring, but overall represents only one contact point.
  • FIG. 3 shows a first embodiment of the present invention.
  • a contact spring 1 is arranged, which leads from an origin 7 to an abutment 6.
  • the contact spring has two contact points 31, 32 on the contact surface 3b opposite a plug 5, which contacts the contact surface 3b as soon as the plug is pushed into the socket.
  • the contact points 31, 32 are located on the continuous or integrally formed spring element 1. However, between the two contact points, a region of the spring which does not contact the contact surface 3b when the plug is inserted. Thus, two separate contact points are formed. It should be noted that the number of consecutive contact points on the spring element need not be limited to two. It can also be realized several consecutive contact points.
  • the two contact points 31, 32 have different spring travel. That is, the contact points are different far away from the spring origin 7. This guarantees that they have a different resonant frequency and, in this respect, begin to vibrate at different vibrations and possibly lose contact with the contact surface. Due to the different spring travel, which come about by the spring geometry, it is ensured in this way that at least one contact point 31, 32 per contact spring has contact at the contact surface.
  • FIG. 4 shows a further embodiment in which the contact spring 1 is divided into two legs 1a and 1b, that is, the spring is not continuous, but in several parts.
  • the two legs 1a and 1b have a different Geometry and a different length.
  • the two legs 1 a and 1 b each have a contact point 31, 32 for contacting the contact surface 3 b of the plug 5 to be inserted.
  • the different lengths of the respective legs of the contact spring, the contact points have different properties again in this case so that they could lose contact with the plug or its contact surface with different vibrations or vibrations.
  • the advantages of the present invention reside in the fact that different resonance frequencies of the individual contact points in the event of vibrations lead to the fact that always a contact is maintained, as well as by the use of multiple contact points generally greater contact reliability.
  • the latter is particularly important in contamination of a contact point or a contact point of importance, as there are still more contact points or points are available and so the contact is ensured.
