Definitions

  • the invention relates to a plug connector for making an electrical connection with a battery terminal.
  • a plug connector is needed to make a reliable electrical connection with a battery terminal.
  • the electrical connection must be capable of withstanding vibrations.
  • the plug connector should be of simple construction and be easily placed on the battery terminal.
  • DE 197 18 448 A1 discloses an electrical plug connector which receives a substantially cylindrical pin part in a substantially cylindrical chamber of a socket part.
  • An annular resilient contact element is arranged in an annular groove in the contact-making region between the pin part and the socket part.
  • An annularly arranged helical spring serves as the contact element. The helical windings of the spring are arranged at an angle to the axis of the helix.
  • a contact protection means should be provided to make direct contact with the battery terminal difficult.
  • the battery contact should also be protected, by a housing to avoid direct contact.
  • the plug connector comprises a housing formed by joining an upper shell and a lower shell with a contact lying within the housing.
  • the contact has a helical spring contact and a contact strip bent to form a cylindrical region.
  • the upper shell and the lower shell each have a holding element extending within the cylindrical region formed by the contact strip, in order to form a recess for holding the helical spring contact.
  • Figures 1 and 2 illustrate a battery terminal of a 36-volt or 42-volt battery for a motor vehicle.
  • the terminal has a cylindrical portion or post 2 projecting out of a battery housing 1.
  • the cylindrical portion or post 2 is surrounded at least in a region adjacent the battery housing 1 by a contact ring 3 (comprising for example, copper) and has its free end covered by a protective cap 4.
  • the protective cap 4 is of substantially axially symmetrical construction and latches to the cylindrical portion or post 2.
  • the protective cap 4 tapers towards its free end and has a peripheral narrowed portion 5 and an oblique face 6 between the narrowed portion 5 and the tapered free end of the protective cap 4.
  • the cylindrical portion or post 2 is surrounded by a protective ring 7, forming an annular gap or space between the cylindrical portion or post 2 and the protective ring 7.
  • the protective ring 7 has a cut-out 8 along a portion thereof to receive a plug connector for making an electrical connection with the cylindrical portion or post 2.
  • the protective ring 7 is configured to prevent inadvertent contact with the contact ring 3 of the battery.
  • one or more projections 9 may be provided on the protective ring 7 to engage in corresponding recesses in a mating plug connector associated with the cylindrical portion or post 2 surrounded by a protective ring 7. The protective ring 7 may thereby prevent the battery from making contact with unsuitable plug means (which does not have the recesses corresponding to the projections 9).
  • FIG. 4 illustrates an exploded illustration of an exemplary plug connector according to the invention.
  • the plug connector has a housing upper shell 10 and a housing lower shell 11 which may be connected to one another by way of first latching elements 12 and second latching elements 13 to form a plug connector housing.
  • Both the housing upper shell 10 and the housing lower shell 11 have a contact region 14 which comprises a cylindrical recess in which the battery terminal is to be received.
  • the housing upper part 10 and the housing lower part 11 each have a supply region 15 which receives a power cable (not shown) for distributing power from the battery.
  • a contact 16 Arranged in the housing between the housing upper shell 10 and the housing lower shell 11 is a contact 16 which has a contact portion 17 and a helical spring contact 20.
  • the contact portion 17 comprises a contact strip 18 which is bent substantially into a cylindrical portion.
  • the contact strip 18 is preferably made from an electrically conductive material, such as a conductive metal.
  • the contact portion 17 also has a power supply portion 19 for making contact with the power cable.
  • the helical spring contact 20 is arranged in the interior of the cylindrical portion of the contact strip 18.
  • the spring contact 20 cooperates with the contact strip 18 and the contact ring 3 to make an electrical connection between the contact portion 17 of the plug connector and the contact ring 3 of the battery terminal.
  • the helical contact spring 20 initially slides along the protective cap 4 toward the copper contact ring 3.
  • the diameters of the cylindrical portion or post 2 and the cylindrical contact strip 18 are selected such that in the mated state the windings of the helical spring contact 20 are tilted beyond their normal angle of tilt in the direction of the spring axis. This means that a restoring force acts on both the cylindrical portion or post 2 of the plug connector and the inner face of the contact strip 18.
  • the cylindrical portion or post 2 and the contact strip 18 are electrically connected by each winding of the helical spring contact 20 in compressed contact with both the cylindrical portion or post 2 and the contact strip 18.
  • the helical spring contact 20 may be fixed with respect to the contact strip 18.
  • the housing upper part 10 has a first holding element 21 and the lower housing part 11 has a second holding element 22.
  • the first and the second holding elements 21, 22 lie substantially opposite one another in the interior of the cylindrical region of the plug connector and form a recess in which the helical spring contact 20 is held.
  • the first and the second holding elements 21, 22 therefore form the cylindrical region in the plug connector in which the cylindrical portion or post 2 is arranged in the mated state.
  • the width of the recess formed by the first and the second holding elements 21, 22 corresponds substantially to the width of the helical spring contact 20.
  • the plug connector may be secured to the battery terminal by a spring 23 which is disposed in a groove 24 in the housing upper shell 10 and cooperates with the narrowed portion 5 on the protective cap 4.
  • the spring 23 is opened by sliding contact along the oblique face 6 of the protective cap 4. The spring 23 then latches in the narrowed portion 5.
  • the plug connector is moved in the direction of the axis of symmetry of the cylindrical portion or post 2 during mating.
  • Figure 6 illustrates a cross-section through a plug connector in a mated state with a battery terminal.
  • a recess 26 is formed by the first holding element 21 and the second holding element 22.
  • the helical spring contact 20 is located in the recess 26.
  • the end faces of the first and the second holding elements 21, 22 forming the recess 26 have a ramp that tapers in the direction of the axis of the cylindrical region.
  • the recess 26, as illustrated in Figure 7, tapers enough to contain the inserted helical spring contact 20 in the recess 26.
  • the tapered ramps on the end face of the first and/or the second holding element 21, 22 resist removal of the helical spring contact 20 from the recess in the direction of the interior of the cylindrical region.
  • the housing upper shell 10 and the housing lower shell 11 are latched together in the assembled state and receive the contact 16 between them.
  • the housing upper shell 10 and the housing lower shell 11 have complementary latching elements 12, 13.
  • latching elements 12, 13 are provided both in the supply region 15 and in the contact region 14 surrounding the cylindrical portion or post 2.
  • the housing upper shell 10 Provided on the housing upper shell 10 are two flexible arms 25, as shown in Fig. 4 which have the groove 24 (shown in Fig. 5) for receiving the spring 23.
  • the spring 23 can be opened by a lever action and the plug connector can be removed from the battery terminal. It is particularly advantageous that, in the mated state, the entire plug connector is arranged within the protective ring 7, as a result of which a great deal of space can be saved.
  • the plug connector according to the present invention has the advantage that the upper and lower shells 10, 11, which are electrically non-conductive, completely surround the contact 17, hence forming a contact protection means.
  • a plug connector of this kind can be constructed in a simple way, since the upper and lower shells only need each to have a holding element in order to hold the helical spring contact. Other measures for fixing the helical spring contact to the contact element are not therefore necessary. Instead, the spring contact is held, when the upper shell and lower shell are in the assembled state, in a recess formed by the holding elements. Thus, when the plug connector is mated on the cylindrical portion or post of the battery terminal, the helical spring contact cannot be pushed in the axial direction of the cylindrical region of the plug connector. Accordingly the helical spring contact is prevented from being withdrawn from the cylindrical region of the contact strip when the plug connector is removed from the battery terminal.
  • one of the holding elements or both holding elements are shaped such that the recess tapers in the direction of the interior of the cylindrical region in order to resist removal of the helical spring from the recess in an inward direction. In this way, the risk that the helical spring contact of the plug connector will become detached from the recess formed by the holding elements when the plug connector is unmated is reduced.
