    Such rechargeable batteries are used in wireless electronic devices, particularly in electric power tools such as battery operated vacuum cleaners. The battery is detachably connected to the electronic device and can be separated from the electronic device for charging and charged by the charger. The battery has a plurality of battery packs disposed of in the battery housing for establishing an electrical connection between the battery and the electronic device or the charger. A battery is known from the published application DE 10 229 980 A1, in which the contact element is in the form of a contact element which is arranged open in the rear wall. The contact elements are easily in contact with the outside but do not protect the contact elements from mechanical or other effects. A battery of this type is known from the published application DE 10200403 6209 A1. In order to protect the contact assembly from mechanical damage, a cover is used which covers the contact assembly and is arranged with the contact assembly in the recess of the rear wall.

    It is an object of the invention to further develop such a rechargeable battery as mentioned at the outset such that when the battery is connected to an electronic device, the contact assembly can be protected from splashed water in a structurally simple manner. According to the invention, this object is achieved in a general kind of rechargeable battery, wherein the cover forms a contact housing which completely surrounds the contact assembly in the circumferential direction and is formed on its side facing away from the step. An insertion opening of the sealing surface that surrounds the circumferential edge of the outer casing. By providing a circular peripheral edge that completely encloses the insertion opening of the contact housing in the circumferential direction, the contact assembly can be protected from splashed water in a simple manner by the sealing ring when the battery is connected to the electronic device. The circumferential edge forms a sealing surface on which the sealing ring can be placed. Since the contact housing does not have any other openings that can be accessed from the outside except for the insertion opening, and the contact housing directly abuts the step, the bottom side of the recess extends through the step to the outside of the rear wall of the battery case Therefore, the contact assembly is well protected from mechanical damage, and by connecting the battery to the electronic device using a sealing ring interposed between the battery and the electronic device, the optimal protection of the contact assembly can be achieved in a simple manner, Damaged by spilled water. The contact housing is preferably of a parallelepiped configuration and has a bottom wall that rests on the underside of the groove in a face-to-face contact, a cover wall that is disposed in an outer plane of the rear wall of the battery casing and parallel to the bottom wall, and A side wall that is vertically aligned with the rear wall, each of the side walls facing a narrow side of the groove. The contact housing is preferably integrally connected to the battery housing but constitutes a separate component that is separate from the recess of the rear wall of the battery housing. Specifically, the bottom wall of the contact housing is not formed by the bottom side of the recess, but a separate bottom wall that contacts the outer casing. In such a configuration, the circumferential edge of the insertion opening surrounding the contact housing is formed in the circumferential direction by the free end edge of the aforementioned contact housing wall facing the end wall of the battery case. When the battery is mounted on an electronic device, the seal ring can be placed on the circumferential edge. The contact assembly can include a plurality of contact elements, which can be, for example, in the form of a contact spring or a stylus. Advantageously, the contact housing has a dividing wall vertically aligned with the bottom wall, the dividing wall extending from the step to the insertion opening and dividing the interior of the contact housing into a first contact space and a second contact space. By means of this partition wall, the different contact elements of the contact element can be mechanically and electrically isolated from each other in a simple manner. It can be provided that the contact assembly comprises four contact elements, a single contact element being positioned in the first contact space, and three contact elements arranged in a line in close proximity to one another being positioned in the second contact space. The electrical connection between the contact elements arranged in the first contact space and the contact elements arranged in the second contact space is reliably prevented by the partition walls. The contact elements arranged in the first contact space preferably form a first voltage connection of the battery, in particular the positive pole of the battery, while the contact elements in the middle of the three contact elements arranged in the second contact space preferably form a battery The second voltage connection, in particular, the negative pole of the battery. Thereby the two voltage connections are separated from one another by a dividing wall, and in the second contact space, the contact elements forming the voltage connection of the battery are surrounded by two further contact elements. It can be provided that the contact elements arranged on the side of the second voltage connection, for example, the negative pole, are constructed as sensors. With the sensor, a measurement signal can be picked up from the battery and supplied to a charger or an electronic device. For example, the state of charge of the battery can be tested by a sensor and transmitted to the display device of the electronic device or charger. In an advantageous embodiment, the contact element of the second contact space arranged next to the dividing wall is constructed as a temperature sensor. The temperature inside the battery case can be picked up by this temperature sensor. The contact element of the second contact space which is furthest from the partition wall is preferably constructed as a resistance sensor. With the resistance sensor, the battery resistance corresponding to the rated voltage of the battery can be picked up by, for example, a charger. The charger can compare the value of the picked-up resistor to the value of the resistor stored in the table, which corresponds to the specific rated voltage of the battery. Thus, it can be determined in a simple manner whether the battery is providing a rated voltage of, for example, 12V or 24V. In an advantageous embodiment of the invention, in order to establish a detachable connection between the battery and the electronic device or charger, the connecting member is arranged at each of the narrow sides of the recess. Specifically, a vacuum cleaner, a high-pressure cleaner or a cleaner driven by an electric motor can be used as the electronic device. Advantageously, the connecting member extends only within the recess without protruding outward beyond the outside of the rear wall of the battery housing. Therefore, like the contact housing disposed of in the recess, the connecting member is protected from mechanical damage even when the rechargeable battery falls into the ground inadvertently. Therefore, the risk of damaging the connecting member is kept low. The connecting members are preferably configured as guiding ribs facing each other, the guiding ribs being separately arranged with respect to the bottom side of the recess and extending up to the outside of the rear wall of the battery case. It is particularly preferred that the guiding ribs together with the outer side of the rear wall of the battery casing and the wall of the cover housing define an abutment surface for abutting the battery on the support surface of the electronic device. The abutment surface enables the battery to be face-to-face abutted on the support surface, thus maintaining the battery particularly stable. The power tool can include a connector corresponding to the recess of the rear wall and the contact housing, the connector having a connecting element that can be introduced into the contact housing of the battery via the insertion opening. The connecting element is preferably constructed as a plug-in socket that receives a contact element of a contact assembly in the form of a contact spring or a stylus. The connector of the electronic device can have an abutment surface that corresponds to the circumferential edge of the contact housing and can form a sealing surface for the seal ring positioned between the abutment surface and the circumferential edge. Therefore, the connecting member of the electronic device and the contact member of the battery can be protected from the splashed water in a simple manner.
