Definitions

  • the invention relates to the contacting of battery poles.
  • the invention relates to a battery terminal for producing an electrical contact with a pole of a battery, in particular a motor vehicle battery.
  • the invention relates to a manufacturing method for producing such a battery terminal.
  • a battery terminal for making electrical contact with a pole of a battery has a clip and a fastener.
  • the clamp has a ring section, a departure section and two tabs.
  • the ring portion allows a flat abutment of the clamp on a pole pin of a battery and thus forms the electrical contact with a low contact resistance.
  • the outlet portion extends radially outwardly from the ring portion and provides the ability to connect the clamp to an electrical conductor, such as a cable.
  • the tabs also extend radially outward from the ring portion, and are spaced apart and parallel to each other so that the diameter of the ring portion can be reduced as the two tabs are compressed toward each other.
  • the fastening element such as a screw, a nut or a quick release, is attached to the two tabs so that the two tabs can be pressed together via the fastening element.
  • the clamp is shaped such that the fastener, when released, can not be removed from the clamp.
  • the battery clamp according to the invention is characterized in that it has a low weight, which can be achieved by reducing the amount of raw material required and by a possible reduction of the fastener.
  • the fastening element has a flange and a tab of the clamp has a flange, wherein the flange and the flange engage each other such that the tabs of the clamp are pulled away from each other when the fastener is released or opened.
  • the curl may be a bending of an edge of the tab such that a gap is formed in which a flange may engage the fastener, and the fastener is still easy to turn. The tab on the clamp is thus held on the fastener in a predetermined position in the axial direction of the fastener.
  • the ring portion of the clamp on its inner surface on an embossing.
  • This embossment may for example consist of one or more grooves, which are formed in the radial and / or axial direction of the ring portion. It is noted that the grooves on the inner surface of the ring portion may also be formed in complex shapes. For example, grooves may be provided in the form of characters, such as for a manufacturer and / or type designation of the battery terminal.
  • An embossing on the inner surface of the ring portion leads to an improved twisting and trigger safety of the clamp on a battery pole.
  • the tabs are arranged obliquely to an axis of the ring portion.
  • the angle with which the tabs to the axis of the ring section may be inclined may be between 30 and 40 degrees, and in particular 34 degrees.
  • the oblique arrangement of the tabs leads to improved handling of the battery terminal.
  • the fastener may be a screw which engages in a thread which is formed in one of the two tabs.
  • the screw head on the one hand have a flange which engages in a flange of the other tab, and on the other hand be formed spherical, whereby the engagement of a tool on the screw head can also be made obliquely to the screw axis.
  • the fastening element has a screw and a corresponding nut.
  • the screw or the nut may be rotatably fixed to one of the two tabs and the other member rotatably secured by means of the above-described curl on the other tab.
  • the screw head or the nut may be formed crowned, so that a tool can be attached at an angle to the screw axis during assembly or disassembly.
  • the outlet section may be arranged diametrically opposite the tabs on the ring section.
  • the battery terminal may further include a connector fixed to the outlet portion and adapted to connect the clamp to a live conductor such as a cable.
  • a universally usable battery terminal can be provided, on which, depending on the intended use of different connecting elements, the contact is made to a current-carrying conductor.
  • the connecting element can be welded, soldered, riveted or otherwise firmly connected to the outlet section.
  • the clamp is composed of several parts.
  • the clamp may have a base body, the Ring section, the outlet section and the tabs forms, but these tabs are not crimped.
  • a connecting part may be provided, which encompasses both the tab and a flange on the fastening element and thus provides the possibility of the positive opening according to the invention.
  • the main body of the clamp is a forging or casting.
  • a clamp is preformed, a fastener used and the fastener connected to a tab of the clamp such that in particular a positive opening of the battery terminal is realized.
  • the preforming of the clamp from a sheet can be done in a stamping-bending-drawing process.
  • this shape can be bent as a ring portion, wherein the outlet portion and the tabs are pulled in each case in other directions away from the ring portion and / or bent.
  • a high rigidity of the clamp is achieved.
  • connection of the fastener to a tab is formed by crimping the edges of the tab, the crimped edges gripping over a flange formed on the fastener such that the fastener is not from the tab is removable.
  • the fastener is a screw which engages in a thread formed in a tab itself
  • the connection can be formed after insertion of the fastening screw.
  • a tab can be crimped before the fastener is used.
  • connection of a tab with a fastening element is effected by a separate connecting part.
