Definitions

  • the invention relates to a battery clamp, which has a metallic clamp body in the form of a radially slotted ring, a clamping device acting on the ring ends and a connecting device for an electrical conductor to be connected to the clamp.
  • the invention has for its object to provide a battery terminal which is also suitable for very high currents and which makes it possible, with little effort, to ensure a high contact quality which does not deteriorate, or at least not significantly deteriorates, even over long periods of time.
  • the teeth provided on the inside of the ring guarantee a uniform contact with the outer surface of the battery pole, which ensures optimal contact between the terminal body and the battery pole, which is a prerequisite for achieving maximum current carrying capacity of the battery terminal.
  • the teeth arranged in the area between the radial slot and the opposite location are opposite the radial direction in the circumferential direction of the Ring inclined towards the point opposite the radial slot. This results in a certain amount of tooth suspension, which is sufficient to compensate for large tolerances.
  • the resilient pre-tensioning of the teeth when the battery clamp is installed helps to suppress negative influences on the contact quality through thermal expansion.
  • the cross section of the annular part of the clamp body that supports the teeth is preferably rectangular in the region of the base of the grooves present between the teeth.
  • This rectangular cross section also leads to grooves, the longitudinal axis of which runs parallel to the longitudinal axis of the channel formed by the annular part of the clamp body, which is useful for producing the battery clamp from a drawn profile, but also for working out the grooves from an annular one Body, is of great advantage.
  • the cross section of the part of the clamp body forming the ring of a particularly advantageous embodiment decreases from the ring ends towards the point opposite the radial slot. It is particularly advantageous here if the cross section of the ring has a size that results in an at least approximately the same bending stress.
  • connection device for the electrical conductor is also of great importance.
  • the connection device is therefore designed as a compression sleeve with a wall thickness that varies in the circumferential direction.
  • a press sleeve is advantageous in many respects compared to differently designed connection devices. Only the usability for aluminum cables and the high contact pressure that can be achieved are mentioned here as examples.
  • a form of the compression sleeve according to claim 6 is particularly advantageous with regard to the manufacturing and assembly effort, because a circular cylindrical longitudinal bore of the compression sleeve is particularly favorable in terms of production technology and the pressing can be carried out by means of a compression tool having a circular cylindrical compression channel.
  • the number of corners of the polygon forming the outer contour of the compression sleeve increases, the differences in the radial compression become smaller, it is advisable not to choose more than eight corners.
  • a tight closure of the press sleeve which prevents the contact quality between the press sleeve and the conductor from being impaired by external interference, can be achieved in a particularly simple manner if the press sleeve is designed according to claim 9, since then the end section lying inside the press sleeve is pressed the cable insulation forms a seal.
  • the compression sleeve is formed with a flange coaxial with its through hole, the head of the tensioning screw being located after the section of the sleeve longitudinal bore serving to accommodate the conductor end.
  • the clamp body and the compression sleeve are respectively suitn by one from a section bar formed g th piece. This minimizes the manufacturing effort.
  • the rectangular or square outer contour of the compression sleeve which results when a profile bar is cut to length, is particularly advantageous for a radial compression which differs in the circumferential direction of the conductor when the compression sleeve is pressed round.
  • the round pressing of the pressing sleeve during pressing is also advantageous in that the pressing tool required for this is particularly simple and can be attached to the pressing sleeve in any angular position.
  • a battery connection terminal for establishing a connection suitable for high currents between an aluminum cable 1 and the pole of a battery formed by a conical bolt has a terminal body 2 in the form of a radially slotted ring.
  • a flange 3 is formed on one ring end, and a flange 4 lying parallel to it is formed on the other ring end, between which the radial slot of the clamp body 2 continues outwards.
  • a through hole 5 of the flange 3 is perpendicular with its longitudinal axis on the radially extending central plane of the slot 7 dividing the clamp body 2 and passing through the center of the clamp channel 6 formed by the clamp body 2.
  • the other flange 4 which is provided with a through hole 8 aligned with the through hole 5, is formed in one piece on the side facing away from the flange 3 with a compression sleeve 9, the longitudinal axis of which is aligned with the longitudinal axis of the through hole 8.
  • the material from which these two parts are made is a compressible aluminum.
  • the clamp body 2 and the compression sleeve 9 are cut to length from a drawing profile.
  • the compression sleeve 9 therefore has a rectangular outer contour in the uncompressed state, such as
  • Fig. 2 shows. It consists of an aluminum alloy that is much harder than the aluminum from which the finely stranded core 11 is made.
  • the inside diameter of the longitudinal bore 10 of the compression sleeve 9 is adapted to the outside diameter of the core 11 of the aluminum cable 1 which is designed as a rope.
  • the inside diameter of the longitudinal bore 10 is matched to the outside diameter of the insulation 12 of the aluminum cable 1. It is then ensured that in a round pressing, in which the compression sleeve receives a substantially circular cylindrical outer surface, as shown in FIG.
  • the compression sleeve in the area of the schematically indicated pressing points 13 not only an optimal contact formation with the soul 11 including an optimal compression of this Soul is achieved thanks to the uneven radial compression, but also a completely tight seal in the end portion receiving the insulation 12. From this free end of the compression sleeve 9, no moisture or other external interference can get into the interior of the compression sleeve and to the stripped end section of the core 11.
  • a clamping screw 15 which in the exemplary embodiment is made of stainless steel, and which penetrates the two through bores 5 and 8 of the flanges 4 and 3, respectively. Since the compression sleeve 9 is pressed in the area surrounding the head 14 in such a way that a tight seal is formed, no moisture or other interferences can get into the interior of the compression sleeve 9 through the through holes 8.
  • Contact grease which is filled into the compression sleeve 9 before pressing, prevents air pockets in the interior of the compression sleeve 9.
  • the clamping screw 15 cannot rotate relative to the compression sleeve 9 and the flanges 4 and 3.
  • a nut 16 resting on the side of the flange 3 facing away from the flange 4 can therefore be tightened without having to secure the clamping screw 15 against rotation by means of a tool.
  • the center of the clamping channel 6 formed by the clamp body 2 is offset from the center of the cylindrical outer surface of the clamp body 2 towards the point of the clamp body 2 opposite the slot 7.
  • the cross section of the annular part of the clamp body 2 decreases from the ends carrying the flanges 3 and 4 towards the point opposite the slot 7, in such a way that when the two flanges are clamped together, approximately the same bending stress is applied to the annular one Part of the clamp body is achieved.
  • the clamping channel 6 delimit teeth 17, between each of which there is a groove 18.
  • nine teeth are provided.
  • the longitudinal axis of all grooves 18 runs parallel to the longitudinal axis of the clamping channel 6.
  • the cross section of the annular part of the clamp body 2 is therefore a rectangle in the region of the groove base of each groove 18, which leads to the same bending stress over the entire axial length of the clamp body 2.
  • the grooves 18 can be provided on the drawing profile, which is advantageous in that the grooves 18 are then not incorporated. But even if the grooves 18 have to be worked in later, a position parallel to the longitudinal axis of the clamping channel 6 is advantageous.
  • all the teeth are inclined in the circumferential direction towards this point with respect to the radial direction, which promotes an even contact of all the head surfaces 17 ′ on the battery pole, because the teeth 17 can better compensate for tolerances.
  • all the grooves 18, with the exception of the two grooves lying next to the central tooth, are formed with parallel flanks.
