Problems solved by technology

In this case, it has proven to be disadvantageous that such an infrared transmission device can only be used to a limited extent, since obstacles to the transmission may be arranged between the hand-held power tool and the external interface or the movement of the user may at least partially interrupt the corresponding Connection
Furthermore, this infrared connection can only be used for a limited effective range
In the case of a permanently integrated infrared transmission device, it has proven to be disadvantageous that replacement of the infrared transmission device is often not possible and / or that the replacement process is complex and cost-intensive

Embodiment Construction

[0044] figure 1 An electrical appliance designed as a hand-held power tool 300 is shown, which is designed, for example, as a cordless drill. Accordingly, in the illustrated embodiment, hand-held power tool 300 is mechanically and electrically connected to battery pack 100 for a grid-independent power supply. However, it should be pointed out that the invention is not restricted to battery-powered drills, but can be used in various hand-held power tools 300 which are operated with battery pack 100 . The hand-held power tool 300 has a not shown transmission 330 arranged in the housing 305 and a handle 315 for transmitting the torque generated by a drive motor 335 , also not shown, around the axis of rotation. x-rotating drive shaft on which a tool receiver 320 is fixed. Hand-held power tool 300 has a control unit 370 in housing 305 , which is in electrical and / or mechanical contact with drive motor 335 and / or transmission 330 . Handle 315 serves as a rest surface for the han...

Abstract

The invention describes a hand-held power tool, which discloses a housing with a handle, a drive motor arranged in the housing and a first interface, wherein the interface is designed to be accessed from at least one external The second interface receives and / or transmits information to at least one external second interface. According to the invention, it is provided that the housing has a receiving opening, wherein the first interface is removably arranged in the receiving opening. Furthermore, the receiving opening is releasably closed by a cover, wherein the cover closes the housing to the outside.

Description

technical field [0001] The invention relates to hand-held power tools and tool systems. Background technique [0002] Electric hand-held power tools are known in principle and are supplied with current via a mains connection. Alternatively, the accumulator enables a high degree of flexibility in operation, since it is in particular independent of the mains current. In this way, for example, outdoor work can be carried out conveniently, so that more provision is made to use the battery pack when operating the hand-held power tool. [0003] Such battery packs are known in principle and have rechargeable batteries, usually a plurality of battery cells connected in parallel and / or in series. Within the scope of the present application, a battery pack is therefore to be understood as a battery pack, preferably composed of a plurality of electrically connected battery cells, which can store electrical energy and provide the energy required for operating the hand-held power tool....
