Embodiment Construction

[0047] figure 1 The reference number 1 in as a whole designates an example of a working device according to the invention. in accordance with figure 1 In an embodiment of the invention, the working device 1 is an electrohydraulic, battery-operated cutting device (knife). The working device 1 comprises a housing 12 in which an electric motor 3 in the form of a brushless direct current motor (BLDC motor), a hydraulic pump 2 (piston compressors 2 a, 2 b ) and a hydraulic pump comprising a hydraulic fluid 30 are present. Tank 19 (see also figure 2 and 3 ). Furthermore, a compensating device is provided for compensating the volume of the hydraulic fluid during operation of the working machine 1 . This can be, for example, a flexible membrane or a generally flexible hydraulic tank. An operation panel 25 including a display 14 and an on / off switch 13 is mounted on the casing 12 . The operator can read the operating status on the display 14 . An insertion slot 26 for an excha...

Abstract

The invention relates to a portable working device (1) for portable use, such as a distraction device, a cutting device or a combination device with cutting and distraction functions, comprising a housing (12), an electric motor located in the housing (12), an insertion slot (26) on the working device (1), an energy supply device in the form of a battery (18), the battery (18) or a connection end for connecting to an external electrical energy source is located in the insertion slot (26), a mechanically or hydraulically driven movable piston rod (5) for completing work, in particular spreading and / or cutting and / or lifting and / or pressing work, an electronic control and adjustment device for controlling and / or adjusting the electric motor (3), the invention relates to a control and regulation device for a battery (18), comprising a printed circuit board (8) cast with a casting compound (17), on which electronic components (9) are arranged, on which insertion slots (26) at least one contact element (27) made of an electrically conductive material, preferably a flat contact element oriented in a pushing-in direction, is arranged, in which the battery (18) is pushed into the insertion slots (26), the contact element enables a releasable electrical contact between the battery (18) and the electronic control and regulation device of the working device (1). Furthermore, the contact (27) is divided into a first surface region (41) and a second surface region (42), the first surface region (41) being covered with an electrically non-conductive protective layer (43) and the second surface region (42) being free of a protective layer.

Description

technical field [0001] The present application relates to an electromechanical or electrohydraulic working device for portable use, such as a spreading device, a cutting device or a combined device with cutting and spreading functions or a lifting pressure cylinder (or rescue cylinder). The above is preferably correspondingly used for rescue purposes, but can also be used for work purposes. The present application also relates to a battery for use in a corresponding working device and an arrangement comprising a working device and a battery for operating the working device. Background technique [0002] Portable, motor-driven, electromechanical or electrohydraulic working or rescue devices of the type that are of interest here are used in a variety of applications. For example, there are distracting devices, cutting devices or so-called combined devices, namely devices with cutting and distracting functions, and rescue cylinders, which are used, for example, by mobilized ma...
