Abstract

An arrangement (1) arranged to enclose a circuit board (3) comprising electronic components (5) is described. The arrangement (1) comprises a structure (7) designed to receive the circuit board (3) and the electronic components (5), a housing (9) designed to receive the structure (7), a cover (11) designed to be connected to the housing (9), an electric socket (13) adapted to provide the circuit board (3) with electricity. The electric socket (13) is comprised in at least one of the housing (9) or the cover (11). The arrangement (1) is arranged to enclose the circuit board (3) by the housing (9) and the cover (11), wherein the structure (7) is designed to releasable and at least partly bear against the circuit board (3) and the electronic components (5). A tool (31) comprising an arrangement is also described.

Description

technical field [0001] The present invention relates to hand-held power tools in which the tool is controlled by electronic components mounted on a circuit board. In particular, the invention relates to a device arranged to enclose a circuit board comprising electronic components and a tool comprising the same. Background technique [0002] A hand-held tool, like for example a pickaxe hammer, comprises an oscillating element for effecting the impact on the chisel tool when the pickaxe hammer is used to break concrete or the like. The impact generates a shock wave that is transmitted through the chisel tool to the material to be broken. Impacts also cause strong vibrations within the hammer. Vibration can cause damage to various parts of the hammer. Therefore, parts of the hammer are usually fitted with protection against vibrations, for example in the form of rubber bushings. [0003] Electronic components are used in power tools, which are mounted on circuit boards and ...
