Battery made up of a number of galvanic elements

The invention relates to a battery consisting of a plurality of galvanic elements with end contacts of the same name, a battery housing, electrical Lsiterele- connecting the end contacts.

' ) elements and two battery contact elements of the same name.

Such batteries are used for the electrical power supply of electrically operated devices and contain several mono-individual cells, in particular primary cells from the system Lithium.

Known batteries of the type mentioned at the beginning are equipped with push-button connections as battery contact elements, which, however, are not sufficiently secure against confusion and, since they protrude from the battery, are at risk of short-circuits. In addition, such batteries have an unfavorable geometry and offer * space utilization.

Proceeding from this, the invention is based on the object To create a battery of the type mentioned, which allows a mix-up and short-circuit-proof contact with the smallest possible housing dimensions.

As a technical solution it is proposed that the two 8atteriekontaktelemente are designed as a two-pole contact socket and that the two-pole contact socket is centrally located in the «Battery case is arranged.

The invention is based on the basic idea of using a single two-pole contact socket and arranging it centrally in the housing * _; ;

In a practical embodiment of the invention, five p galvanic elements arranged in a circle around the contact socket, which is preferably located in a front housing cover, which can be locked in particular with the rest of the housing. |

Hereby, the advantage is achieved that Polvertauschungen and I KurzschluSUberbrückungen the battery contact elements at about housing parts barren like. Impossible and optimum use of space j. be guaranteed within the battery housing.

According to a further development of the invention, cutouts prevent |

inside the battery housing for play-free mounting of the one |

individual galvanic elements short circuits, especially with the I.

Battery contact elements inside the battery housing. Ii

I An inventive battery housing preferably consists of two injection-molded plastic parts, namely a box and a lid. The two-pole contact socket extends inside the battery housing in a recess naturally formed by the galvanic elements, while a corresponding two-pole contact pin is located on the device to be supplied with electrical power. The individual galvanic elements are wired to one another in the usual way and connected to the two-pole contact socket.

The box-lid connection is preferred as a snap connection executed, but adhesive or welded connections are also conceivable.

Further details, features and advantages of the subject matter of the invention emerge from the following description of the

the same battery in a front view from the direction B according to FIG. 1 and

Fig. 4

the same battery with cover from the direction A according to FIG. 1.

An inventive Bstteriegehäuee 1 consists of a after Box 2, which is open at the top, and a cover 4 that is snap-fastened therewith by means of a closure 3.

The box 2 has approximately cylindrical partitions 5, 6, the five recesses 7 for receiving individual cylindrical galvanic elements 8 without play and a central cylindrical recess 9 for receiving a two-pole one in the cover 4 centrally arranged contact socket 10 form.

The individual galvanic elements 8 are parallel to one another or in series by means of insulated electrical conductor elements, in particular conductor wires 11 permanently or detachably between their End contacts 12, 13 connected, the gusset-shaped cavities formed between the galvanic elements 8 and the intermediate walls 5, 6 being preferred for laying the conductor elements 11 be used.

The outer contour of the box 2 is preferably adapted to the dimensions of the galvanic elements (FIG. 3), so that

result in a very small battery volume and a secure hold of the galvanic elements within the box 2. Only the den The edge 14 of the box 2 carrying the lid 4 is preferably designed in the shape of a circle, corresponding to the lid 4.

Two of the conductor elements 11 are connected at their free ends to the two-pole contact socket 10 in an electrically conductive manner. as Contact socket 10 is preferably a so-called jack built-in socket which reaches through a cover opening 15 and is screwed on the outside with a nut 16, this calibration still being located within a cover recess 17, ISO that (.) The contact socket 10 does not protrude beyond the surface of the cover.

The closures 3 are preferably located in the from the outer Surface of the box 2 formed gusset areas 18, so that despite the solid locking of the lid its dimensions are those of the galvanic elements 8 practically does not exceed predetermined maximum external dimensions.
