Definitions

  • the invention relates to a contact element according to the preamble of claim 1.
  • contact elements are used, in particular in the automotive industry, which interact with contact pins of various shapes.
  • the contact pins can e.g. be designed as flat plug contact pins, round plug contact pins or plug contact pins with a square cross section, the contact elements for example as flat plug contact sleeves or the like.
  • These plug connections connect individual conductor strands, for example. If several contact elements are combined in a connector housing, complete cable harnesses are also connected to one another.
  • relay modules or fuses are usually connected to the plug-in base plate of the central electrical system in the central electrical system of motor vehicles via such plug connections. The circuits come together in this plug-in base plate and are switched there with the relay modules or fused centrally with the fuses. Since not every consumer can be secured individually for reasons of space, multiple consumers are often secured together.
  • the fuses usually consist of plug-in fuses with a fuse link, such as those e.g. are known from DE-G 81 11 548.2.
  • the disadvantage here is that when the fuse is triggered, not only is the circuit interrupted in which an overcurrent occurred, but also all other circuits which are protected by this fuse, as a result of which areas essential for the operation of the vehicle are often shut down. Will one triggered such a fuse, it must be replaced disadvantageously. In addition, such fuses can age or corrode, especially in the contact area, so that the contacting becomes worse, which is associated with the known disadvantages, such as, for example, increasing the resistance and impairing safety.
  • a further disadvantage is that devices for which the fuse should trigger at relatively low fault currents cannot be combined in a common circuit, or total damage to the device is likely when combined.
  • the object of the invention is to protect line systems simply and inexpensively.
  • a fuse module is integrated in a contact element between a contact area, for example a flat plug contact sleeve, and a connection area assigned to it, or between a contact pin and the connection area assigned to it, which connects the connection area and contact area or contact pin in an electrically conductive manner.
  • the fuse module triggers reversibly when loads occur, ie, after the overload is removed, the circuit is unlocked again.
  • Such fuse modules consist, for example, of so-called PTCR elements (Positive Temperature Coefficient Resistance) or bimetallic fuse elements.
  • PTCR elements can consist, for example, of metals, the electrical resistance of which increases with the temperature, here usually a linear behavior, so that the resistance increases in proportion to the temperature. The resistance can become so high that the element blocks the current flow.
  • Another type of PTCR element consists of a predominantly crystalline plastic matrix in which conductive particles are finely distributed, these conductive particles being located in the amorphous regions of the matrix. If the matrix contains a sufficient number of such particles, they form an electrically conductive three-dimensional network.
  • the PTCR element cools below a certain temperature, there are again sufficient crystalline areas in the plastic matrix so that the element is again electrically conductive.
  • fuse elements can therefore be produced that trip reversibly, i.e., interrupt the current flow only when the overload occurs, but are conductive again under normal load.
  • Such elements are mass-produced very inexpensively and can have a miniaturized design.
  • An embodiment of a contact element 1 consists of a contact area 2, a fuse module 3 and a connection area 4, which are connected one behind the other in an electrically conductive manner.
  • the contact sleeve can be, for example, a flat plug contact sleeve, round plug contact sleeve, pin contact sleeve, a flat spring arm contact element or a similar element for receiving plug contacts, this sleeve having a connection device 5 for a fuse module 3.
  • the fuse module 3 can be, for example, a PTCR element, preferably a polymeric PTCR element, but also a bimetal fuse module, the fuse module 3 having at least one connection device 5 for a contact area 2 and at least one connection device 5 for a connection area 4.
  • the connection area 4 can have, for example, crimp pins 6 for clamping a conductor wire, screw terminals, receiving elements for solder connections of a conductor wire or the like, wherein it has at least one connection device 5 for a fuse module 3.
  • the contact element 1 can also be formed from two identical contact areas 2 and a fuse module 3 arranged between them.
  • Such a contact area can also be, in particular, a connection area 9 in order to connect a conductor wire directly by soldering, crimping or a cutting / clamping connection.
  • connection devices 5 can be designed, for example, in such a way that the fuse module 3 can be connected to the contact area 2 and the connection area 4 by means of welding, riveting or soldering (FIG. 1, FIG. 2).
  • connection devices 5 can be designed, for example, as a plug connection, so that plug elements 8 of a fuse module 3 can be inserted in a form-fitting manner or as a press fit into sockets 9b of the contact area 2 and the connection area 4 (not shown), or plug elements 8 of the contact area 2 and the connection area 4 are inserted into plug-in channels 9a of the fuse module 3 (FIGS. 3 to 8).
  • the plug elements 8 can be designed as tongues or pins with a round or rectangular cross section.
  • the plug-in elements 8 can also be designed as plastic self-tapping screws or be provided with a toothing.
  • the advantage here is that such an embodiment allows a particularly short design.
  • the plug connection is preferably not detachable.
  • the securing module can, for example, be approximately plate-shaped, the plates having two flat outer sides 10 and four end faces 11.
  • the hollow cylindrical plug sockets 9 provided for receiving the cylindrical contact pins 8, for example, can be connected next to one another in one end face 10 or each on opposite end faces 10.
  • the contact elements are made up of pluggable fuse modules 3, contact areas 2 and connection areas 4, the user can combine individual contact elements with fuse modules 3 for securing different current strengths or special contact areas 2 or connection areas 4.
  • contact element 1 provides for the contact area 2 and the connection area 4 to be provided with crimping arms for the clamping holding of essentially cylindrical connecting pieces of the securing module 3 (not shown), the arrangement in relation to one another basically being able to correspond to the first embodiments.
  • the contact element can then be covered, for example, with insulating film or shrink film, so that it is insulated from the outside except for the plug opening for a plug or the plug. This is particularly the case when two conductor strands are to be connected to one another with this contact element.
  • the contact element can also be introduced into the connector housing and thus serve, for example, to connect cable harnesses, but also as a connection to a consumer.
  • fuse modules trip reversibly, that is, they are not replaced after each trip, but are reset to the operating state when the overload is removed. This is particularly advantageous when used in the automotive field, since the contact elements according to the invention with fuse modules can be distributed maintenance-free anywhere in the vehicle. As a result, individual circuits are specifically protected and the provision of a central fuse box can be omitted.
  • a particular advantage of using polymeric PTCR fuse modules in the contact element lies in the fact that the error rate is particularly low with these electronic components. Furthermore, the contact elements according to the invention can be mass-produced by machine and further processed cost-effectively.
