In this case, the line protection device simultaneously protects the lines from, in particular mechanical, damage caused by components or parts of components, such as, for example, by capacitors or contact pins of the components, such as capacitors, plug-in couplings, resistors and the like. At the same time, the line protection device is designed to conduct the lines through the housing. This can prevent damage and / or squeezing of the lines during assembly of the hand-held power tool, in particular of the screwdriver. Further, the wire protection device can prevent the wires from crossing within the housing.In one embodiment of the hand-held power tool, the line protection device has at least one alignment element which is designed to align at least one energy supply line relative to the activation unit. The alignment element can be designed, for example, as an alignment pin, wherein a plurality of alignment pins is also possible, such as, for example, two, three, four or more than four. It is also possible for the alignment element to be designed, for example, as an alignment rail, an alignment web, an alignment projection or an alignment edge. The housing may form the alignment element, such that the housing and the alignment element are integral. The power supply unit has two power supply lines. The power supply lines are provided to electrically connect the power supply unit to the control unit, in particular the control unit board. In this case, the energy supply lines can conduct electrical energy from the energy supply unit to the control unit, in particular the control unit printed circuit board.

The spacer is configured to space the activation line from the other components, such as capacitors, so that there is a small distance between the activation line and the capacitor. This prevents the activation line from scrubbing the capacitor during operation of the hand-held power tool and prevents heat from the capacitor from being absorbed by the activation line. Furthermore, the spacer element prevents a force from being exerted from the activation line to the electrical component. A substantially permanent contact of the activation line and the other component may result in solder joints and / or solder wires being damaged. The receptacle for the activation unit has an opening through which the activation line can be guided. After the activation line has been passed through the opening, the spacer element allows the activation line to be conducted to the control unit board in a substantially unimpeded manner.

The support element can be arranged, in particular radially to the tool axis, at least partially between the drive motor and the control unit printed circuit board. The control lines are lines for controlling the drive motor. The control lines can be for example for the sensor circuit board or for supplying the drive motor with electrical energy. A plurality of control lines can also be provided, such as two, three or more than three. The control lines may include a connection point disposed axially between the drive motor and the transmission. The support element is designed to support a weight of the control line and at the same time to space pins from lines which are connected to the control unit board or from solder pins. This enables scrubbing to be prevented. The control line then rests at least partially on the supporting element. The support element can also guide the control lines of the drive motor to the control unit board.In one embodiment of the hand-held power tool, the line protection device has at least one guide element which is arranged between the drive motor and the control unit printed circuit board. The guide element is designed to guide the control lines to the control unit board. The housing may be connected to the guide element. It is possible for the housing to form the guide element, so that these are integral. The guide element can be designed, for example, in the manner of a web, a wedge, a truncated cone, a truncated pyramid or a projection. It is also conceivable for the guide element to be designed, for example, as a groove, a shell, a shaft or a recess. Furthermore, the guide element can be designed, for example, as at least one adhesive drop which, on the one hand, envelopes electrically insulating pins of electrical components and, on the other hand, prevents the control line from being able to be brought into its intended place during installation of the hand-held power tool. The support element can be formed axially adjacent to the guide element. The control line can rest on the guide element. If three control lines are provided, these can rest on the guide element.In one embodiment of the hand-held power tool, the guide element is designed to space at least the control line from the control unit printed circuit board. The guide element is designed to space the control line from pins of electrical components or other lines. These pins may protrude through the control unit board and damage the control line during operation.

The housing and the motor receptacle can be connected to one another in a form-fitting, force-fitting and / or materially integral manner. It is also possible for the housing to form the motor receptacle, so that these are integral. The motor receptacle has a web which is designed to guide the control line. The control line can lie on the web of the motor receptacle, so that the control line can be arranged radially between the guide element and a part of the motor receptacle and can be placed therebetween. As a result, the control line can be fixed radially.The housing can form the alignment element, the feed-through element, the spacer element, the support element, the guide element and the motor receptacle. At least one of the half shells can form these.Brief Description of the DrawingsThe invention is explained below with reference to preferred embodiments.
