Definitions

  • the invention relates to a battery clamp with a metallic clamp body in the form of a ring, which on its side facing the center has teeth integrally formed with it, the head surfaces serving as the contact surface forming part of a conical surface, and with a connecting device for one with the clamp connecting electrical conductor.
  • the invention is based on the object of providing 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.
  • a battery clamp of the type mentioned at the outset in that the part of the clamp body which forms the ring has a radial slot, that a clamping device acts on the ring ends and that the teeth arranged in the region between the radial slot and the point opposite it are inclined with respect to the radial direction in the circumferential direction of the clamp body against the point opposite the radial slot.
  • the teeth Due to their inclined course, the teeth experience a certain elastic deformation when the clamping device is closed. This relatively low tooth suspension is not only sufficient to compensate for large tolerances.
  • the resilient pre-tensioning of the teeth when assembled ensures, above all, that negative influences on contact quality are suppressed by thermal expansion. In addition, this bias counteracts a displacement of the battery terminal and a resulting deterioration of the contact. Thanks to the radial slot of the ring and the clamping device acting on the ring ends, the clamping force required for good contact quality can always be applied regardless of tolerances.
  • the cross section of the annular part of the clamp body which 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 of great advantage for the production of the battery clamp from a drawn profile, but also for the working out of the grooves from an annular body.
  • 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. For example, only the usability for aluminum cables and the achievable high contact pressure should be mentioned.
  • a form of the compression sleeve according to claim 5 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 compression can be carried out by means of a compression tool having a circular cylindrical compression channel. Since with increasing number of corners of the polygon forming the outer contour of the press sleeve, the differences in the radial pressing become smaller, it is expedient to choose the number of corners not greater than eight.
  • 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 8, since then the inside of the press sleeve lies when pressing End portion of the cable insulation forms a seal.
  • the compression sleeve is formed on one flange coaxially 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 press sleeve are formed by a piece cut to length from a profile bar. 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 7 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 on the side facing away from the flange 3 in one piece 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 press sleeve 9 therefore has a rectangular outer contour in the uncompressed state, as shown in FIG. 2. 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. 3, the compression sleeve in the region of the schematically indicated pressing points 13 not only an optimal contact formation with the core 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 press 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 press sleeve 9 through the through bores 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 can not 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, as shown in FIG. 1, 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, an approximately equal bending stress of the annular part of the Terminal body is reached.
  • 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 it is then unnecessary to incorporate the grooves 18. But even if the grooves 18 have to be machined in laterally, 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 location in relation to the radial direction, which promotes an even contact of all head surfaces 17 on the battery pole because so 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.
