Description

The invention relates to a battery terminal according to the preamble of claim 1.

In automotive technology, the power supply of motor vehicles is still largely carried out with the help of rechargeable batteries such as lead acid batteries, which are introduced as easily replaceable components in the motor vehicle approximately in the engine compartment. The accumulators have a substantially standardized shape and dimensions, wherein the two electrical poles of the accumulators are arranged on the upper side of the accumulator and are therefore accessible from above. With regard to the shape and the dimensions of the poles, there are different variants, the most common being a cylindrical or conical configuration of the poles.

The electrical system is connected to the poles of such standardized batteries with the help of so-called battery terminal clamps and set, embrace the usually cylindrical or conical shape of the poles from the outside and set using various clamping and screwing releasably attached to the poles. In this case, the battery terminals have matching to the respective shape of the poles of the battery terminal clamps formed clamp or the like. On the outside abut the poles and their assignment to the poles z. B. can be secured by clamping screws. For this purpose, the battery connection terminals are plugged onto the poles in the relaxed state until the clamping straps are fully seated on the poles and then the clamping straps are clamped to one another, for example by a clamping screw, and then a radial clamping force is applied to the poles. As a result, vibrations or shocks from the driving operation of the motor vehicle can not affect the contacting of the poles with the battery terminals.

There are now a variety of constructions of such battery terminals known with which the permanent, but releasable connection of the battery terminals to be accomplished at the poles of the batteries. So is about from the DE 90 04 073 U1 a battery terminal made of solid material known whose production costs are quite high. Also from the DE 10 2007 032 837 B4 Such massive battery terminals are known.

In order to reduce the costs for the production of battery terminals, it is known to produce the battery terminals at least in sections or even entirely from sheet-like starting materials. The sheet-like starting materials are for this purpose brought in a series of Blechumformungsoperationen in partially complex forms corresponding to the individual sub-functions of the battery terminals associated functional sections. Examples of such battery terminals are in DE 20 2011 000 271 U1 . DE 20 2010 016 521 U1 or the DE 20 2005 006 400 U1 to find. The problem with these battery terminals is that the operation of the clamping screws usually not coincide with the mounting direction of the battery terminals on the poles of the battery and therefore z. B. the clamping screws must be rotated at an oblique angle. This results primarily from the fact that the clamping bracket made of sheet-like material must be formed approximately parallel to the outer shape of the poles and therefore the clamping screws can be arranged only approximately perpendicular or at a shallow angle to the central axis of the poles on the clamping brackets. To operate such arranged clamping screws but a corresponding operating space for screwing tools must be available to operate the clamping screws safely and reasonably comfortable. This is not always safe to ensure in the sometimes cramped installation conditions for batteries in modern vehicles.

For the most common case of installing a battery in the engine compartment, but also for other installation situations, it is advantageous if the actuation direction of the battery terminals would take place from above the accumulator, since usually already by the need to be able to use the accumulator in the receiving compartment , appropriate space must be available. However, this is not or not satisfactorily possible with the previous battery terminal blocks of sheet-like starting materials.

Object of the present invention is therefore to provide a battery terminal of sheet-shaped starting materials, which has a substantially operable from above the accumulator ago actuation and ensures a secure fixing of the battery terminal to the poles of the accumulator.

The solution of the object of the invention results from the characterizing features of claim 1 in conjunction with the features of the preamble. Further advantageous embodiments of the invention will become apparent from the dependent claims.

The invention relates to a battery terminal for fixing a power cable to the pole of a battery or the like., Comprising a substantially cylindrical or conical clamping portion, with which the Battery terminal on the cylindrical or conical pole of the accumulator or the like. Attached in Aufsteckrichtung, and fixed to the clamping portion fixing portion for the power cable, wherein the clamping portion of two oppositely arranged, like a lobe bent and matching the shape of the pole of the battery clamps is formed, which engage around the pole of the accumulator on both sides in sections and the opposite ends of the strap-like bent clamps form a gap between them. Such a generic battery terminal is further developed in accordance with the invention, that at the opposite ends in the region of the gap of the tab-like bent clamp U-shaped bent portions are formed, the free ends facing away from each other are facing and conical in the free ends having trained functional surfaces, two substantially annular clamping body with the U-shaped bent mold sections fitting trained Hintergreifabschnitten on the opposite U-shaped bent mold sections attachable to each other and to the battery terminal terminal are displaced or clamped, and the clamping body in the relative displacement or tension Interacting with the conical functional surfaces of the strap-like bent clamp so that the two clamps of the battery terminal clamp the gap formed between them narrow and clamp the pole of the accumulator include.

By in the region of the ends of the strap-like bent clamp U-shaped bent sections and the conical functional surfaces arranged there, the movably mounted Hintergreifabschnitte the clamp body at a relative displacement or tension to each other either narrow the gap between the two clamps of the battery terminal or expand and thereby pressing the clamp to the pole of the accumulator circumferentially or release the pole of the accumulator again. The conical functional surfaces set vividly z. B. perpendicularly controlled from above the accumulator and vertically extending operation of the clamping body on the cone angle in a displacement / adjustment / deformation of the clamp around, which acts in the circumferential direction of the pole of the accumulator. This allows the operation of the battery terminal z. B. from the existing above the accumulator free space and thereby made comfortable for the operator and the battery terminal are nevertheless made entirely or partially of sheet-like starting materials cost. The clamp bodies are arranged on the battery terminal so that they have a relative adjustability to each other and move in this relative adjustment along the helix angle of the conical functional surfaces. The conical functional surfaces at the ends of the clamp and thus the ends of the clamp itself are adjusted by the relative displacement of the clamp body in the circumferential direction towards or away from each other, whereby the gap between the two clamps reduced or expanded again and thereby made the clamping of the pole or canceled. The helix angle of the conical functional surfaces as well as the degree of relative adjustment of the clamping body to each other while the degree of change of the gap between the two clamping brackets before and can be adjusted within wide limits to required clamping forces. In order to securely fix the clamp body to the clamps while ensuring their relative displaceability, U-shaped bent portions are formed at the end portions of the clamp, the free ends of which face away from each other and which have the conical functional surfaces. At this U-shaped bent mold sections, the clamping body can be securely fixed with corresponding engaging elements and move like a backdrop along the U-shaped bent mold sections and thereby interact in the manner already described with the conical functional surfaces. In particular, the extent to which the clamps extend around the pole of the accumulator, limited only by the relatively small width of the gap between the clamps, whereby the clamps rest almost on the entire circumference of the poles and a correspondingly secure fixing of the battery terminal at the poles. The battery terminal according to the invention, it is possible to produce a stable, securely clamped battery terminal from sheet-like starting materials, which can be conveniently operated from above the battery, in particular perpendicular to the accumulator or parallel to Aufsteckrichtung the battery terminal on the poles. This space problems in the operation of the battery terminal are largely avoided.

In a further embodiment, it is conceivable that the conical functional surfaces are inclined at an angle to the direction of relative displacement or tension of the clamping body. Through this inclined design of the conical functional surfaces, the conical functional surfaces act together with the associated functional surfaces of the clamping body, which may also be conical, as a deflection of the Operating forces of the battery terminal from the vertical in the circumferential direction to the poles of the accumulator. By appropriate choice of the helix angle of the conical functional surfaces, the degree of deflection can be influenced and the strength of the clamping can be influenced. For a simple release of the clamping of the battery connection terminal, for example during repairs or to replace the accumulator, the helix angle of the conical functional surfaces should not be chosen to be self-locking.

In an advantageous embodiment, it is conceivable that the displacement or clamping of the clamp body to each other and to the battery terminal by means of a clamping screw which moves the clamp body parallel to the mounting direction of the battery terminal relative to the clamps towards or away from each other. Such a clamp by means of a screw is easy to use and inexpensive, since unlike other constructions of battery terminals largely standardized standard screws can be used. The operation of the screw takes place advantageously z. B. with a screw head or other operation of above the accumulator.

In order to ensure reliable relative adjustment / clamping of the clamping body, it is advantageous if one of the clamping body has an internal thread which corresponds to the external thread of the clamping screw, while the other clamping body has a passage opening which is larger than the outer diameter of the clamping screw. As a result, one of the clamping body is adjusted by the thread of the clamping screw relative to the other clamping body, which is supported approximately in the longitudinal direction of the clamping screw of the head of the clamping screw. The two clamp bodies interact in the manner already described with the conical functional surfaces of the clamp and narrow / thereby the clamping bracket relative to the circumference of the pole of the accumulator. It is useful in a further embodiment, when the clamping body is arranged with the internal thread on the screw head of the clamping screw opposite end of the clamping screw.

In a further embodiment, the two clamping body may have rear engagement portions, with which they engage behind the U-shaped bent mold sections of the strap-like bent clamping strap and anchor itself relatively displaceable to the conical functional surfaces on the clamping brackets. As a result, the clamping body form with their respective Hintergreifabschnitte and the U-shaped bent mold sections a kind of slotted guide of the clamping body, along which the clamp body can move under support on the conical functional surfaces of the clamp and thereby taking place widening / narrowing of the gap between the clamps. For this purpose, it is advantageous if the two clamp bodies are arranged at a distance from one another on the lug-like bent clamping straps relative to the clamping screw, when the battery connecting terminal is in the relaxed state and this distance is reduced when the clamping straps of the battery terminal clamp become narrower.

In a further embodiment, it is conceivable that the conical functional surfaces of the opposing hook-like curved mold sections are formed conically such that they form two mutually inclined partial surfaces with a tip pointing outwards V-shape, each of the mutually conically inclined faces with each one of the clamp body can act together. As a result, each of the two clamping bodies slides on one of the conical faces and adjusts the clamps in the manner already described.

For better power transmission, it is also conceivable that conical functional surfaces are formed on the clamping brackets both in the region of the opposite ends of the strap-like bent clamp and in the U-shaped receptacle for the hook-like curved rear engagement portions of the clamp body. As a result, an improved power transmission of the actuating force of the clamping screw is achieved on the thin-plate-like clamping bracket, since the support of the clamping body is distributed to the clamping brackets on a larger area. It is thereby prevented that the relatively thin-walled sheet-like cross sections of the clamps are deformed unduly and the clamps can deform in extreme cases so that a secure terminals of the pole is no longer possible. In a further embodiment, it is conceivable here that both in the region of the opposite ends of the strap-like bent clamping strap and in the U-shaped receptacle for the hook-like curved rear engagement portions of the clamping body conically shaped functional surfaces are aligned and arranged parallel to each other. As a result, both conical faces work equally on the clamping body and it is the already described enlargement of the support surface without negatively influencing the mobility of the clamping body.

It is furthermore advantageous if the clamping bodies are designed as deformed, preferably cold-extruded or sintered components, since such production methods make a very compact and solid design of the geometrically complex shaped Allow clamping body. However, it is also conceivable to produce such clamping body also from sheet-like starting materials or in other ways.

It is also advantageous to fix the clamping body and the clamping screw captive on the battery terminal, as this can be prevented about when repairing that a part of the battery terminal is lost unintentionally. For this purpose, in an advantageous embodiment, the clamping screw such a length and the clamping body have such dimensions that the clamping screw completely passes in the relaxed state of the battery terminal both clamping body and protrudes opposite the screw head from the there arranged clamping body. This allows the free end of the clamping screw after mounting the clamping screw and the clamping body on the battery terminal changed in such a way, preferably pressed or deformed, that the clamping body can not be removed from the clamping screw.

Furthermore, it is advantageous if the clamping body when loosening the clamping screw so change their position to the conical functional surfaces of the strap-like bent clamp that widen the strap-like bent clamp when loosening the clamping screw by itself and the battery terminal thereby detachable from the pole of the accumulator or is freely removable. This can avoid that by a single z. B. firmly corroded clamping body even after loosening the clamping screw, the battery terminal still sits firmly on the pole of the battery and the pole is not free.

A particularly preferred embodiment of the battery terminal according to the invention is shown in the drawing.

Show it:

1 - An advantageous embodiment of the battery terminal according to the invention in a spatial exploded view of the items,

2 - The battery terminal according to the invention according to 1 in a front view,

6 - The battery terminal according to the invention according to 4 in a sectioned side view.

The 1 shows a particularly advantageous embodiment of the battery terminal according to the invention 1 in a spatial exploded view of the individual parts, from the basic structure and the assignment of the individual parts of the battery terminal 1 is recognizable. In the 2 and 3 is the battery terminal according to the invention according to 1 then shown in a planar front view and a planar side view. Same part numbers designate the same parts.

The battery connection terminal 1 is made in substantial parts of a sheet-like starting material by punching and cutting operations and has a fastening portion in a conventional manner 2 for a not further shown cable of a motor vehicle, which can be connected to a likewise not shown cylindrical or conical pole of a rechargeable battery, also not shown.

For this the battery connection terminal points 1 an arrangement of two the pole of the accumulator circumferentially about each half embracing clamp 3 on that at their end areas 13 through a gap 18 are separated. This clamp 3 are due to their dimensions and their material of a sheet-shaped starting material elastically deformable and thereby form a receiving space 17 for the pole of the accumulator. The clamp has a geometry that is fundamentally adapted to the shape of the pole of the accumulator, in this case they are each bent almost semicircular and can thereby create the slightly conical outer shape of the pole of the accumulator. The dimensions of the clamp are chosen such that the clamps are in the non-tensioned state easily plugged onto the pole of the accumulator, the plug movement in the insertion direction 21 he follows. In that regard, the basic structure of the battery terminal is 1 known in itself.

The inventive clamping of the pole of the accumulator now takes place in the manner described below.

The clamps 3 indicate their in the area of the gap 18 arranged ends U-shaped bent mold sections 20 on, on both sides of the gap 18 are arranged opposite each other and their end portions facing away from each other. These U-shaped bent mold sections 20 form on both sides of the gap 18 each a hook-like basic shape, the U-sections pointing away from each other and thus also the later explained conical functional surfaces 14 facing each other away from each other. The U-shaped bent mold sections 20 extend substantially parallel to the plugging direction 21 , where from the 3 it can be seen that the exact alignment of the U-shaped bent mold sections 20 a little inclined to the direction of insertion 21 runs, namely is inclined by half the cone angle of the pole of the accumulator. The U-shaped bent mold sections 20 are in themselves but linear again extends.

On the thus formed U-shaped mold sections 20 can now be two essentially disc-shaped clamping body 4 . 5 attach and relative to the U-shaped curved sections 20 move. For this purpose, the clamp body 4 . 5 on one side a dovetailed groove 11 on whose edges by Hintergreifabschnitte 12 be narrowed, with the groove 11 dimensionally substantially to the cross-sectional shape of the U-shaped bent mold sections 20 fit. The clamp body 4 . 5 can be perpendicular to the sheet thickness of the clamp on the U-shaped bent mold sections 20 attach and move in a more detailed manner relative to it. The cross-sectional shape of the groove 11 Can over the entire thickness of the clamping body 4 . 5 be formed consistently, but it is also conceivable, individual parts of the cross section of the groove 11 conical shape.

The clamp body now serve to the U-shaped bent mold sections 20 the clamp 3 and thus the clamp 3 even so elastic deformation that the clamp 3 is pressed against the peripheral shape of the pole of the accumulator and is held securely on this. For this purpose, the U-shaped bent mold sections 20 at their end faces, facing away from each other end regions conically shaped surfaces 14 on, leading to the middle of the clamp 3 extend forward and thereby describe a very flat V-shape. Measure or the distance of the U-shaped bent mold sections 20 is in this central region of the conical molding surfaces 14 larger than at the top and bottom sections of the clamp 3 ,

Insert now from above and from below ever one of the clamp body 4 . 5 with their grooves 11 on these as described shaped U-shaped bent mold sections 20 on and moves the clamp body 4 . 5 towards each other and in the direction of the tip of the V-shape of the conical molding surfaces 14 , so are the clamp body 4 . 5 with their grooves 11 the U-shaped bent mold sections 20 aufeinender to press, because the conical shaped surfaces 14 on the inside shape of the grooves 11 rest and be pushed together. This reduces the width of the gap 18 and the clamps 3 be in the recording room 17 and pressed to the outer contour of the pole of the accumulator located there. This creates a frictional connection between clamp 3 and pole of the accumulator through which the battery terminal 1 is securely fixed to the pole of the accumulator. The relative displacement or tension of the clamping pieces 4 . 5 each other is using the conical shaped surfaces 14 and the grooves 11 in a pressing movement of the clamp 3 implemented.

Now this relative displacement or tension of the clamping pieces 4 . 5 easy and simple for an operator to carry out and the clamping state of the battery terminal 1 to secure, serves a clamping screw 6 holding a screw head 7 here in the form of a hexagon head and a threaded section 16 having. The clamping screw 6 passes in the assembled state, the two clamp body 4 . 5 wherein in the lower clamp body 4 a matching mating thread 9 is present, with the threaded portion 16 the clamping screw 6 works together. The clamp body 5 has a through hole 10 on, through which the clamping screw 6 just step through it. At the screw head 7 opposite end is a compression 8th the clamping screw indicated after mounting of clamping bodies 4 . 5 and clamping screw 6 at the U-shaped bent form sections 20 can be made and prevents loss of individual parts of this preassembled module.

This preassembled assembly of clamping bodies 4 . 5 and clamping screw 6 act now such that upon actuation of the clamping screw 6 due to the thread in the clamping piece 4 this is on the screw head 7 to move and thereby the distance between the clamping pieces 4 . 5 is reduced. The two clamping pieces slide 4 . 5 on the conical shaped surfaces 14 towards the top of the V formed thereby and press in the already described manner the clamp 3 together, causing the clamps 3 clamped against the pole of the accumulator. After reaching this clamping state, this state is due to the self-locking effect of the thread 16 the clamping screw 6 kept upright. Will the clamping screw 6 turned back in the opposite direction, so this clamp is released and the clamp 3 widen again, leaving the battery terminal 1 can be removed again from the pole of the battery.

The clamped condition of the battery terminal 1 show the 4 in a spatial view and the 5 and 6 in a plan view and a sectional side view.

As in particular the 4 and 6 can be seen, are in this clamped state, the clamp body 4 . 5 only a little in the direction of insertion 21 spaced apart, but are not adjacent to each other to ensure the clamping action.

In the plan view according to 5 is again to recognize more exactly how the groove 11 and the rear grip sections 12 on the U-shaped shaped sections 20 are attached and anchored to this so that the clamping pieces 4 . 5 parallel to the U-shaped bent form sections 20 are held displaceably. It can also be seen that the conical molding surfaces 14 not only at the end-side end portions of the U-shaped bent mold sections 20 can be arranged, but also within the U-shaped bend of the clamp 3 itself. As a result, a doubling of the transfer surface for the transmission of the clamping forces of the clamping screw 6 between the clamping pieces 4 . 5 and the clamps 3 achievable, which can be safely prevented that too strong tightening the clamping screw 6 the sheet-shaped starting materials and therefore formed with relatively small material cross-sections U-shaped bent mold sections 20 be deformed inadmissible.
