Description

Battery pole, battery, connection element and contacting arrangement for connecting a battery pole with a connection element

The invention relates to a battery terminal and a connection element for producing a contacting arrangement, a battery having such a battery terminal and a

Contacting arrangement. The contacting arrangement serves to connect a battery terminal, in particular a vehicle battery terminal, to a connection element for producing an electrical connection between a battery and an electrical consumer, in particular a vehicle electrical system. The battery pole has a substantially round horizontal cross section over its vertical extent.

It is known that an electrical energy store, in particular a battery for a vehicle, has two electrical poles, which can be connected by means of pole terminals to an electrical system of the vehicle. The battery poles usually have a substantially round horizontal in their vertical extension direction

Cross section on; usually the poles of vehicle batteries are cylindrical. The associated connection elements, the so-called pole terminals, are usually designed as an open ring whose diameter - as in a pipe clamp - can be changed by means of a screw. In this way, such a pole terminal can then be fixed non-positively to a battery pole. Fiddling with a screwdriver may result in a short circuit while touching the positive pole and the body.

For a tool-free contacting of the battery terminals connecting elements in the form of spring clips are known, which are closed by a lever;

so-called quick clamps or quick-release closures. This type of clamp is intended primarily for vehicles that are only seasonally commissioned, as the stability of the spring may suffer in continuous operation. DE 20 2005 002 593 U1 and DE 19 34 180 U describe the connection of a cable to a battery terminal of a motor vehicle battery by means of a

Bayonet catch.

The invention has for its object to provide for tool-free production of a reliable electrical contact between battery terminal and terminal a comparison with the prior art improved battery terminal and an improved connection element for producing an improved contacting arrangement, as well as an improved battery with a corresponding battery.

The object is achieved with respect to the battery pole by the in claim 1, with respect to the battery by the in claim 3, with respect to the connection element by the in claim 4 and with respect to the Kontaktierungsanordnung by the features specified in claim 8.

Advantageous embodiments of the invention are the subject of the dependent claims.

A for contacting a battery, in particular a vehicle battery, with an electrical load, in particular with a vehicle electrical system, provided contacting arrangement comprises at least one battery terminal and at least one attachable to the battery pole contact element. In this case, the battery pole has a substantially round horizontal cross section over its vertical extent. According to the invention, a lower portion of the battery pole in horizontal

Sectional plane has a smaller diameter than an upper portion of the battery connected to the lower portion. Accordingly, the battery post shows the upper portion having a bottom opposite the lower portion protruding bottom. The battery pole has at least one groove extending in the vertical direction of the battery pole for carrying out a form element of the connection element from the upper section to the lower section. The surface of the upper portion is - except for the opening of the upper portion through the at least one groove - designed substantially rotationally symmetrical. The underside has at least one ramp-shaped area. The at least one ramp-shaped region is formed starting from the at least one groove and with respect to a direction of rotation about a vertical axis of the battery pole increasingly leading down. A contact region of the connection element is in the patch on the battery pole state at least partially positively on the upper portion of the battery. The connection element is by means of the formula element by rotation in the direction of rotation The bottom side can be fixed. By clamping the element against the ramp shaped area as a result of the rotation, the connection is secured.

In other words, by rotating at least one component of the

Connection element in the direction of rotation of the mold element against the bottom are clamped. Here, the mold element engages under the underside or the mold element is supported on the underside. In this way, the connection element can be set particularly securely on the battery pole. In addition, the flat contact of the terminal element in the contact region at the upper portion of the battery pole ensures a particularly low contact resistance for electrical current at this point.

In particular, the at least one molded element may be clamped between the underside of the upper portion of the battery post and a battery top on which the battery post is located. As a result of this clamping of the at least one molding element, the contacting arrangement can be brought into a locked state in a particularly simple manner, in which the connecting element is secured against becoming detached from the battery terminal.

Such an arrangement allows the production of a secure and permanent connection, for example, a vehicle battery with the electrical system, without the

Using a tool: The connecting element is from above on the

Battery pole mounted, wherein the mold element is guided by the vertical groove of the upper portion of the pole down, where it can be clamped by subsequent rotation of the connection element at the partially ramped bottom. In particular, therefore, no screwdriver for the production of electrical contact is required. As a result, the risk of the occurrence of a short circuit between the battery and the tool can be largely excluded, whereby the risk of fire is reduced.

Furthermore, the invention relates to a battery, in particular a pole of a

Vehicle battery, which is connectable to a corresponding attachable connection element to a contacting arrangement of the type described.

The battery pole has a substantially round horizontal cross section over its vertical extent. According to the invention, a lower section of the battery post in the horizontal sectional plane has a smaller diameter than an upper section of the battery post connected to the lower section. Corresponding the battery pole shows the upper portion, which has a lower than the lower portion protruding bottom. The battery pole has at least one groove extending in the vertical extent of the battery pole. By means of the at least one groove, a shaped element of the connecting element can be guided from the upper section to the lower section. The underside forms at least one ramp-shaped area. The at least one ramp-shaped region is formed starting from the at least one groove and with respect to a direction of rotation about a vertical axis of the battery pole increasingly leading down. Thus, the connection element by means of the formula element by rotation in the direction of rotation at the bottom can be fixed.

Such a designed battery pole allows, in interaction with the corresponding connection element, a reliable electrical contact, wherein for the preparation of the connection between the battery and the terminal no tool is required. The surface of the upper portion is - except for the opening of the upper portion through the at least one groove - substantially

designed rotationally symmetrical, so that the connection element after putting on the pole and the passage of the formula element through the groove quite easily, simply by rotation, can be clamped to the lower-side ramp. In other words, the connection element can be braced against the underside of the upper section of the battery pole, which region is ramped in regions, that is to say in the vertical extension direction of the battery pole. In this way, the connection between the battery and the pole

Secure the connection element.

Particularly advantageous is an embodiment of the battery, wherein the upper portion comprises two extending in the vertical extent of the pole grooves which face each other, and accordingly on the underside of the upper portion also have two ramp-shaped areas, each starting from the two grooves down to lead. By a symmetrical design a particularly comfortable handling and a more uniform connection of the pole with the corresponding connection element can be displayed. In addition, the force can be particularly well distributed when contacting the upper portion of the battery with the terminal element, with which the contact region of the connection element, in particular flat, is pressed against the upper portion of the battery.

Furthermore, the invention relates to a battery, in particular a vehicle battery, with at least one, as previously described trained battery. A Battery according to the invention, which is equipped with such battery poles, can be particularly easily and safely replaced if necessary, since - by means of the contacting arrangement described - can be connected without the aid of a tool to an electrical load.

In addition, the invention relates to an electrical connection element for connecting at least one electrical load, in particular a vehicle electrical system, with a battery pole, wherein the connection element can be placed on the battery and can be fixed to the battery terminal.

The connecting element can be connected to the described battery pole to the described contacting arrangement by the connecting element

can be placed on the battery pole by means of a contact region. The contact region is formed by a rotationally symmetrical formed and a curvature having Kontaktierungseinsatz, wherein an inner contour of the contact region at least partially with an outer contour of the upper portion of the battery

corresponds when a surface of the upper portion substantially

is designed rotationally symmetrical. The connecting element has at least one

Form element, which by at least one in the vertical extent of the

Batteriepols extending groove therethrough from the upper portion of the battery, which has a bottom opposite a lower portion projecting bottom, to just this lower portion - that is, to said underside - is feasible. At least one ramp-shaped area of the underside of the mold element can be fixed by rotation in the direction of rotation. The ramp-shaped area is for this purpose, starting from the at least one groove and based on a direction of rotation about a vertical axis of the battery, increasingly leading down. The connecting element comprises a lever element which is used to lock the

Contacting arrangement with respect to the Kontaktierungseinsatz is rotatable. Thus, the connection element can be particularly easy to bring into a locking position in which the connection element is securely held on the battery.

By means of the connection element of the electrical consumer without an aid, in particular without a tool, can be arranged and fastened to the battery pole or to a battery, wherein an electrical contact between the

Connection element and the battery is made. The connection element described allows a reliable contact between the battery and the terminal by the terminal element in

attached state at least partially positively on the upper

Section of the battery terminal rests. By clamping the element in a ramped portion of the underside of the upper portion of the battery post by rotation, the connection is also secured.

A further embodiment provides that the lever element comprises a lateral lever, wherein the connecting element can be fastened by means of the lever element to the battery pole formed in this way. By means of the side lever, the turning and fixing of the connection element on the battery pole is facilitated.

In one development, the lever element has the at least one molding element. Thus, the connection element is almost an integral part of the lever element.

The contact area for making the electrical connection between the

Batteriepol and the connection element is advantageously formed by means of the Kontaktierungseinsatzes in the lever element. In other words, the contacting insert can be introduced into a receiving region of the lever element, in particular inserted. The contacting region or contact region is-like the upper section of the battery pole-rotationally symmetrical in shape and has a curvature that corresponds at least in sections to the substantially-except for groove-shaped recesses-rotationally symmetrical outer contour of the battery post.

In particular, by means of the electrical contacting arrangement, other electrical connections, in particular in a vehicle, can also be electrically connected to one another and securely fastened to one another without the aid of a tool.

The advantages and preferred embodiments described for the contacting arrangement according to the invention also apply to the battery pole according to the invention, the battery according to the invention and the connection element according to the invention and vice versa.

Battery 9 arranged pole. 8

The pole 8 protrudes from a battery top 9.1 substantially in the vertical direction R and comprises two sections 8.1, 8.2.

A lower section 8.1 is arranged downstream of the upper side of the battery 9.1 and has a smaller diameter in the horizontal sectional plane than an upper section 8.2 connected to the lower section 8.1 and further away from the upper side of the battery 9.1.

Overall, the pole 8 of the battery 9 shown in FIG. 11 essentially has a mushroom-shaped form: the lower, stem-shaped portion 8.1 is cylindrical, the upper portion 8.2 in the representation shown substantially hemispherical. Alternatively, the pole 8 may also have other substantially rotationally symmetrical formations, as shown in FIGS. 16a and 16b, and be designed, for example, in the shape of a helical-head.

The upper portion 8.2 of the pole 8 has two extending in the vertical direction of extension R grooves 8.2.1. The grooves 8.2.1 face each other, wherein a third width b _{3 of} the grooves 8.2.1 is greater than the second width b _{2 of} the formed on the lever element 5 form elements 5.4 in the form of locking lugs.

The symmetry of the surface of the upper portion 8.2 of the battery pole is interrupted by the recess of the grooves, which, however, do not affect the functionality of the surface with respect to rotation, so that the surface is nevertheless to be regarded as "substantially" rotationally symmetrical. The position of the grooves 8.2.1 at the upper portion 8.2 of the battery 8

corresponds to the position of the form elements 5.4 at the lower portion 5.3 of the lever element 5. The grooves 8.2.1 serve as insertion aids for insertion of the

Batteriepols 8 in the lever element 5 and in the Kontaktierungseinsatz 3, as shown in Figure 12 in more detail.

The form elements 5.4 can be guided through the grooves 8.2.1 until the contact region K, in particular the curved inner contour of the contacting insert 3, is arranged on an outer contour of the upper section 8.2 of the pole 8.

An underside 8.2.2 of the upper section 8.2 has two ramp-shaped areas, which are formed such that they extend from each of a groove 8.2.1, and with respect to a direction of rotation D about the vertical axis of the pole 8, increasingly to the Close battery top 9.1. The respective approach of the

Bottom 8.2.2 of the upper section 8.2 to the battery top 9.1 as far as possible continuously, the two ramp-shaped areas are concentric.

In this case, a first distance a _{1 of} a top area is 8.2.3 of the upper

Section 8.2 of the pole 8 to a beginning A of the respective ramp-shaped area, starting from the respective groove 8.2.1, smaller than a second distance a _{2 of} the uppermost region 8.2.3 of the upper section 8.2 to one of this groove 8.2.1 in

Direction of rotation D more distant portion of the respective ramped area of the bottom 8.2.2.

Figure 12 shows the connection element 4, consisting of the with the

Connecting element 2 connected electrical line 1, the inserted into the lever member 5 Kontaktierungseinsatz 3 and the lever member 5 itself, in front of a

Put on the pole 8 of the battery. 9

A position of the inside formed on the lever member 5 as locking lugs form elements 5.4 corresponds to a position of 8.2 formed at the upper portion 8.2 of the pole grooves 8.2.1, so that the connection element 4 is unhindered in the appropriate positioning on the battery 8 can be placed.

In the mounted state of the connection element 4 are the form of elements 5.4 of the lever member 5 at the height between the battery top 9.1 and the

Subsection 8.2.2 of the upper section 8.2, wherein a third shown in Figure 15 Distance a _{3 of} an unspecified uppermost area of a

Contact area K forming inner contour of the Kontaktierungseinsatzes 3 to a

5.4.2 of the form elements 5.4 is greater than the first distance Ά of the uppermost portion 8.2.3 of the upper portion 8.2 of the pole 8 to the beginning A of a ramped area and is smaller than the second distance a _{2 of} the uppermost area 8.2.3 of upper section 8.2 to the of a groove 8.2.1, seen here in the clockwise direction, more distant portion of the respective ramp-shaped area. The dimensions of battery post 8 and contact insert 3 thus obey the relationship distance a1 is smaller than distance a ₃ , and distance a ₃ is smaller than distance a ₂ .

After placement shown in Figure 13, the lever member 5 by means of its lever arm 5.1 in a direction of rotation D, here clockwise to the battery 8 are rotated. As a result, position the form elements 5.4 of the lever element 5 between the bottom 8.2.2 of the upper section 8.2 of the pole 8 and the

Battery top 9.1, wherein the two form elements 5.4 of the lever member 5 in an end position of the lever member 5 relative to the pole 8 of the battery 9 between the

Bottom 8.2.2 and the battery top 9.1 are clamped. This locked state of the contacting arrangement is shown in FIG.

Figures 16a, 16b and 16c show three different configurations of a battery 8 with substantially - so with the exception of the groove 8.2.1 - rotationally symmetric surface. FIG. 16a shows a concave vaulted FIG. 16b

frustoconical and Figure 16c is a consistently convex curved surface.
