Definitions

  • the present invention relates to a busbar, in particular for motor vehicles, on which at least one electrically conductive connection element can be fastened to form an electrical contact.
  • busbars are used, for example, in power distribution boxes in motor vehicles, in particular in fuse boxes. It is known to punch such busbars and to connect the connection elements by pressing a pin formed on the connecting element in the perforation with the busbar in order to produce an electrical contact between the busbar and connection element. However, the holding force of such a connection is limited.
  • the invention has for its object to provide a busbar of the type mentioned, which ensures an increased holding force for a connection element.
  • busbar having the features of claim 1, and in particular by the fact that the busbar has a recess which comprises a wall portion which is penetrated by at least one insertion opening for the connection element.
  • a plug-in opening which is formed as a passage opening, is provided in the wall section of the recess, via which the connection element can be fastened to the busbar.
  • the recess formed according to the invention can ensure that the height the recess and thus the effective with respect to the attachment of the connecting element height of the busbar is greater than the thickness of the busbar, so that over known busbars, which do not have the recess according to the invention, an improved mounting of the connection element can be achieved on the busbar. Consequently, a larger contact surface for fastening the connection element can be provided by the busbar according to the invention than in a known busbar.
  • the area of the wall section delimiting the plug-in opening can act as a shoulder for the connection element, which at least makes it difficult or largely prevents loosening or breaking off of the connection element, in particular with forces acting transversely to an insertion direction of the connection element. If the area of the wall section delimiting the plug-in opening is also elastically deformed when a connecting element is pressed in, the area delimiting the plug-in opening can exert a spring force on a connecting element pressed into the plug-in opening.
  • the recess is made for example by deep drawing.
  • the insertion opening in the wall portion of the recess is made for example by punching.
  • two plug openings each passing through the wall section are provided. This ensures that the connecting element several times in the wall portion of Well can be clamped, whereby the holder of the connection element is further improved.
  • the insertion openings are opposite to a recess with respect to a center axis. This ensures that simple and inexpensive to manufacture and / or conventional plate-like connection elements can be used, which can engage with their opposite narrow sides in the respect to the center axis of the recess opposite insertion openings.
  • At least one adjacent opening is provided for the insertion opening, at least one insertion opening or each insertion opening, which passes through the busbar, wherein the adjacent opening is positioned such that between the insertion opening and the adjacent opening arranged in the region of the wall portion and / or web section acting as a bending beam.
  • the web portion for example, due to its dimensions and / or material properties, also have elastic properties, so that - in the manner of a bending beam - a spring force can be exerted on a pressed-in the insertion opening connection element.
  • the depression is pot-shaped or trough-shaped and / or symmetrical with respect to a central axis, in particular rotationally symmetrical.
  • Such recesses are particularly simple and / or conventionally shaped tools, for example conventional shaped punch-die devices, can be produced. In principle, however, the depression can also be designed differently.
  • the recess comprises a recess bottom, which is penetrated by a contact opening, in which for forming an electrical contact, a pin of the connection element can be inserted or pressed.
  • the wall section is then primarily responsible for the attachment of the connection element to the busbar, the recess base mainly responsible for the formation of the electrical contact. In general, however, the wall area will continue to contribute to the formation of an electrical contact and the recess base also for attachment of the connection element.
  • the invention further relates to an arrangement with at least one bus bar, as explained above, to which at least one electrically conductive connecting element is attached to form an electrical contact, which comprises a contact portion which is pressed into the at least one insertion opening of the busbar.
  • the contact portion may be inserted into the insertion opening and / or at least partially passed therethrough.
  • connection element comprises a pin, which is inserted or pressed to form an electrical contact in a contact opening of the busbar passing through a recess bottom of the recess.
  • the invention further relates to a method for producing a busbar, in particular for motor vehicles, to which at least one electrically conductive connection element can be fastened to form an electrical contact, wherein a region of the busbar is selected for fastening the connection element, the region, in particular by deep drawing, in such a way is processed, that a depression is formed, and an edge or wall portion of the area, in particular by punching, is processed such that at least one insertion opening is formed, wherein in the at least one insertion opening, a contact portion of the connection element can be pressed.
  • the plug opening can be formed, or vice versa.
  • the contour formed by the plug-in opening is reworked.
  • the electrically conductive busbar 11 shown in a perspective view in FIG. 1 a and in a sectional view in FIG. 1 b initially has a cup-shaped depression 13 produced by deep drawing, which is formed rotationally symmetrically about a center axis.
  • the depression 13 comprises a circumferential wall section 15 and a recess base 17.
  • the wall section 15 is penetrated by two plug-in openings 19 and 21, which lie opposite one another with respect to the center axis of the recess 13.
  • the plug-in openings 19 and 21 produced by punching are each formed as a slot, which are oriented with their longitudinal extent in each case parallel to the longitudinal direction of the bus bar 11.
  • the recess bottom 17 is penetrated by a circular contact opening 23, which was also produced by punching.
  • the busbar 11 has a thickness d, which is for example 0.6 mm.
  • the bus bar 11 has an effective or functional height h, which corresponds to the total height of the recess 11 and is greater than the thickness d of the bus bar 11.
  • the effective height h is that part of the overall height the bus bar 11, which contributes to the attachment of a connection element explained below to the busbar 11.
  • an electrically conductive connecting element 25 can be fastened to the busbar 11 shown in FIG. 1, as can be seen in the perspective view according to FIG. 2 a and in the sectional view with respect to the busbar 11 according to FIG.
  • the connecting element 25 comprises a plate-like contact portion 27, which is pressed with its two narrow sides in the recess 13 formed in the insertion openings of the bus bar 11 in order to effect attachment of the connection element 25 to the busbar 11.
  • the connecting element 25 further comprises a pin 29, which is positively, or with excess relative to the contact opening 23 to form a press-fit, through which formed in the recess bottom 17 contact opening 23 of the bus bar 11 is inserted therethrough to electrical contact between the connection element 25 and the Busbar 11 to create.
  • the bus bar 11 has an adjacent further opening 31a, 31b on both sides of the plug opening 19 with respect to their longitudinal extension, which pass through the bus bar 11 in each case.
  • the further openings 31a and 31b are positioned such that in each case a web portion 35a, 35b is formed between the insertion opening 19 and the laterally arranged further openings 31a and 31b.
  • the web portions 35a and 35b act in each case as a bending beam, which can press in the direction of the other openings 31a, 31b when pressing a connection element which has an excess compared to the insertion opening 19 in order to facilitate the pressing.
  • adjacent further openings 33a and 33b and associated Web portions 37a, 37b provided for the insertion opening 21 adjacent further openings 33a and 33b and associated Web portions 37a, 37b provided.
  • the further openings 31a, 31b, 33a, 33b are each made by punching.
  • the depression is formed. Thereafter, the insertion openings 19, 21, the contact opening 23 and the further openings 31a, 31b, 33a, 33b are preferably punched out simultaneously. In principle, however, can also be punched first and then deep-drawn.
  • busbar according to the invention a particularly secure attachment for an electrically conductive connection element.
