Definitions

  • the invention relates to a pole terminal according to the preamble of claim 1 and an anti-rotation element for a pole terminal according to the preamble of claim 9.
  • Motor vehicle batteries each have two battery poles arranged in polish on the top side of a battery housing, which projects beyond the bottom of the sidewalls of the poles and have a rotationally symmetrical peripheral surface in the form of a cylinder or a steep truncated cone.
  • the latter is equipped with two battery cables whose free ends are each equipped with a fastening device in the form of a pole terminal.
  • the pole terminals usually comprise a clamp open on one side, which surrounds an eye for insertion of the associated battery pole and two separated by a separating gap laterally projecting clamping jaws which integrally connected to one of the two opposite ends of the clamp and with aligned passage openings for a clamping screw are provided so that the clamping jaws contracted by tightening a nut screwed onto the clamping screw and thereby the clamp can be clamped on the battery post.
  • the rotation of the clamp in this case may cause a mounted on the pole terminal measuring instrument or control device, such as a battery sensor against an adjacent sidewall of the Polish abuts, which poses a risk of damaging the meter or controller and, above all, the risk of damaging signal lines of the meter or controller due to pinching between the terminal or housing of the meter or controller and an adjacent sidewall of the Polish , Under unfavorable circumstances, even the battery cable leading to the terminal block can be crushed and damaged.
  • a mounted on the pole terminal measuring instrument or control device such as a battery sensor against an adjacent sidewall of the Polish abuts
  • the sensor housing of the battery sensor can be adapted in terms of shape and size, that it is supported when attempting to twist in the mounting position of the battery measuring terminal on the housing of the battery, thereby preventing twisting of the battery measuring terminal.
  • this anti-rotation element formed by the sensor housing of the battery sensor is effective only in connection with a pole terminal, in which the battery sensor is integrated with the adapted housing, and on the other hand only in conjunction with a battery type, adapted to the Polish the sensor housing in terms of shape and size has been.
  • this is not guaranteed, especially in the event of subsequent installation of another measuring instrument or control device on the pole terminal, such as another type of battery sensor or when replacing the battery with another type of battery.
  • the sensor housing of the battery sensor between the battery pole and a side wall of the Polish must be accommodated and therefore may have only small dimensions.
  • the present invention seeks to improve a pole terminal of the type mentioned in that on the one hand prevents rotation of the pole terminal by simple means and independent of a mounted on the pole terminal battery sensor and on the other hand, a contact between a mounted on the pole terminal Measuring instrument or control device, such as a battery sensor, and a side wall of the Polish can be avoided when mounting the pole terminal to a battery terminal.
  • a preferred embodiment of the invention provides that the anti-rotation is formed by a stamped and bent sheet metal part having a provided with a passage opening for the clamping screw fastening web and at least one integrally connected to the mounting bracket boom, in a predetermined Mounting position of the pole terminal is suitably aligned parallel to an adjacent side wall of the Polish and abuts with its free end against the adjacent side wall of the Polish when the pole terminal, for example when tightening the clamping screw, is rotated beyond a predetermined maximum angle of rotation out of the predetermined mounting position.
  • Such an embodiment of the anti-rotation element has the advantage that the predetermined maximum angle of rotation decreases with increasing length of the boom and therefore can be easily adjusted by selecting the correct length of the boom.
  • the anti-rotation element preferably has two arms which protrude to opposite sides over the fastening web and advantageously have the same length, so that in each case one of the two arms with its free Ends against the adjacent side wall of the Polish abuts when the pole terminal from the predetermined mounting position in one or the other direction of rotation is rotated by more than the predetermined maximum angle of rotation.
  • the in the Figures 1 and 2 In motor vehicle battery 2 only partially shown in plan view has a plastic housing 4, in the top for each of the two connection or battery terminals 6 (only one shown) of the battery 2, a Polish 8 is recessed. Each polish 8 is bounded by two mutually perpendicular side walls 10, 12 and a flat bottom 14 over which the battery pole 6 projects upwards.
  • the two battery poles 6 have the shape of a cylinder or a steep truncated cone with a flat top end 16 and a rotationally symmetrical to the longitudinal center axis of the battery 6 peripheral surface 18.
  • a pole terminal 20 is fixed in each case, which is conductively connected to the end of a battery cable 22, wherein the one pole terminal 20 connects the positive pole 6 with the electrical system and the other pole terminal (not shown) the negative terminal to the ground of the motor vehicle.
  • the clamping clamp 24 has two front ends with protruding clamping jaws 26, 28, which are separated by an approximately radially extending parting line 30 from each other, and surrounds one of a cylindrical boundary surface 32nd limited eye for the associated battery pole 6.
  • the two jaws 26, 28 are provided with aligned passage openings (not visible) for a clamping screw 34, on which after passing through the openings a nut 36 is screwed with an external hexagon.
  • the two jaws 26, 28 When the nut 36 is tightened after pushing the loosened clamp 24 on the battery 6, the two jaws 26, 28 are compressed and thereby the cylindrical boundary surface 32 of the eye frictionally or non-positively connected to the peripheral surface 18 of the battery 6.
  • a suitable clamping tool for example with a torque wrench, the two jaws 26, 28 are bent slightly to the side of the jaw 28, so that the parting line 30 between the jaws 26, 28 at a steep angle to one of the top or bottom of the clamp 24 spanned plane extends.
  • the pole terminal 20 is provided with an anti-rotation element in the form of a stamped and bent sheet metal part 38, which is releasably and captively secured to the clamp 24 by means of the clamping screw 34 and the nut 36.
  • the sheet metal part 38 comprises an elongated narrow sheet metal strip 40 with flat broad side surfaces whose height H ( Fig. 4 ) expedient not greater than the height of the clamp 24, so be in Fig. 4 downward facing lower longitudinal side edge 44 when attaching the clamp 24 to the battery 6 can not contact the bottom 14 of the Polish 8 before the battery 6 completely penetrates the eye of the clamp 24.
  • H Fig. 4
  • the web portion 52 is clamped between the nut 36 and the adjacent outer side of the clamping jaw 28, while the web portion 50 covers the top of the jaws 28 and possibly a portion of the top of the jaw 26.
  • the metal strip 40 then extends along the side facing away from the clamp 24 side of the clamping screw 34 at the free ends of the clamping jaws 26, 28 over. After attaching the pole terminal 20 on the battery 6, the metal strip 40 extends in the in Fig. 1 illustrated predetermined mounting position of the pole terminal 20 parallel to the adjacent side wall 10 of the Polish 8, wherein it by a narrow gap 66 (FIG. Fig. 1 ) is separated from this.
  • the gap 66 is relatively small and the tolerances of the Polish 8 common automotive batteries are relatively low in this direction, regardless of the type of battery by means of a single anti-rotation element 38 maximum angle of rotation ⁇ can be ensured, which are within small tolerance ranges ,
  • the maximum permissible angle of rotation ⁇ is determined in the described anti-rotation element 38 by the distance between the side wall 10 of the Polish 8 and the opposite broad side surface of the sheet metal strip 40 and by the length of the respective section 62, 64 and can most easily by changing the length of the sections 62nd , 64 can be set to a desired value.
