[0001] Technical Field and Background Art

[0002] The invention relates to a plug connector for electrically connecting an electric line of a motor-driven gardening and / or forestry tool to a plug-in connector, and to a motor-driven gardening and / or forestry tool having a plug-in connector, an electric line and such a plug connector. Summary of the invention

[0003] The object of the present invention is to provide a plug-in connector for electrically connecting electrical lines of a motor-driven gardening and / or forestry tool to a plug-in connector, wherein the plug-in connector has improved properties, and to provide a motor-driven gardening and / or forestry tool having such a plug-in connector.

[0004] The invention achieves this object by providing a plug-in connector having the features of claim 1 and a motor-driven gardening and / or forestry tool having the features of claim 15. Advantageous developments and / or embodiments of the invention are described in the dependent claims.

[0005] The plug-in connector according to the invention is used for electrically connecting the electrical wires of a motor-driven gardening and / or forestry tool to a plug-in connector, and has a plug-in connector receiving section and an electrical wire receiving section. The plug-in connector receiving section has a first flat clamping arm, a second flat clamping arm, a first edge guide wing and a second edge guide wing. The flat clamping arms are arranged opposite to each other. The edge guide wings are arranged opposite to each other. The plug-in plate receiving section is constructed or configured to elastically expand the arm spacing between the flat clamping arms, and to plastically expand the wing spacing between the edge guide wings by means of the particularly direct interaction between the edge guide wings and the plug-in plate for receiving the plug-in plate between the flat clamping arms and the edge guide wings, and to contact the opposite faces of the received plug-in plate by means of the flat clamping arms and to apply a clamping force thereto, and to contact the opposite edges of the received plug-in plate by means of the edge guide wings in order to fix the received plug-in plate to prevent it from being loosened from the plug-in plate receiving section and to make electrical contact. The wire receiving section is electrically, particularly and mechanically connected to the plug-in plate receiving section. The wire receiving section is constructed or configured to receive wires and to fix the received wires to prevent them from being loosened from the wire receiving section and to make electrical contact.

[0006] The elastic expansion of the plug connector, in particular the elastic expansion of the arm spacing and the plastic expansion of the wing spacing, allows the plug connector to be individually adapted to the plug lug, in particular to a thickness or thickness with tolerances and to a width of the plug lug with tolerances. As a result, the plug connector, in particular the plug lug receiving section, can receive or seat the plug lug without play and can thus secure the received plug lug very well, in particular against the occurrence of high speeds of up to 1000 meters per square second (m / s) caused by the motor-driven gardening and / or forestry tool, in particular the drive motor of the gardening and / or forestry tool, such as, for example, a combustion motor. 2 ) and / or also when the same plug-in sheet is received or inserted into the same plug-in sheet receiving section multiple times or the same plug-in sheet receiving section is plugged onto the same plug-in sheet multiple times. As a result, the plug-in connector, in particular the plug-in sheet receiving section, can make relatively safe electrical contact with the received plug-in sheet. In addition, the flat clamping arms and the edge guide wings can each make electrical contact with the received plug-in sheet and thus make redundant electrical contact with the received plug-in sheet.

[0007] In particular, the plug-in connector can be referred to as a contact spring or a contact plug.

[0008] The plug-in piece can be referred to as a plug-in tongue. As a supplement or alternative, the plug-in piece can be plate-shaped.

[0009] The electric line can be a cable or a core wire.

[0010] The connector receiving section and the cable receiving section can be different. In addition or as an alternative, the first flat clamping arm, the second flat clamping arm, the first edge guide wing and / or the second edge guide wing can be different.

[0011] The plug-in plate receiving section can be constructed to elastically expand the arm spacing in the following area, in which the flat clamping arm contacts the received plug-in plate. As a supplement or alternative, the plug-in plate receiving section can be constructed to elastically expand the arm spacing between the free ends of the first flat clamping arm and / or the second flat clamping arm. In addition, as a supplement or alternative, the plug-in plate receiving section can be constructed to elastically expand the arm spacing with a minimum amplitude of 10%, in particular with a minimum amplitude of 20%, in particular with a minimum amplitude of 50%, in particular with a minimum amplitude of 100%. In addition, as a supplement or alternative, the plug-in plate receiving section can be constructed to plastically expand the arm spacing. In addition, as a supplement or alternative, the flat clamping arm can be called a spring arm.

[0012] The plug-in sheet receiving section can be constructed to plastically expand the wing spacing in the following area, in which the edge guide wing contacts the received plug-in sheet. As a supplement or alternative, the plug-in sheet receiving section can be constructed to plastically expand the wing spacing between the free ends of the first edge guide wing and / or the second edge guide wing. In addition, as a supplement or alternative, the plug-in sheet receiving section can be constructed to plastically expand the wing spacing with a minimum amplitude of 1%, in particular with a minimum amplitude of 2%, in particular with a minimum amplitude of 5%, in particular with a minimum amplitude of 10%. In addition, as a supplement or alternative, the plastic expansion of the wing spacing can be carried out when the plug-in sheet is first received or first inserted into the plug-in sheet receiving section or when the plug-in sheet receiving section is first plugged onto the plug-in sheet.

[0013] The lug receiving section can be designed to elastically expand the arm spacing and to plastically expand the wing spacing independently of one another.

[0014] The value of the force for receiving or inserting the plug-in sheet into the plug-in sheet receiving section, in particular along the plug-in sheet receiving direction, or plugging the plug-in sheet receiving section onto the plug-in sheet can be a minimum of 10 Newtons (N), in particular a minimum of 20 N and / or a maximum of 40 N, in particular 30 N. As a supplement or alternative, the force for releasing the received plug-in sheet from the plug-in sheet receiving section, in particular counter to the plug-in sheet receiving direction, can be a minimum of 10 Newtons (N), in particular a minimum of 20 N and / or a maximum of 40 N, in particular 30 N.

[0015] The plug lug receiving section can be connected to the received plug lug in a force-fitting manner, in particular in a form-fitting manner. As a supplement or alternative, the plug lug receiving section does not need to be connected to the received plug lug in a materially fused manner.

[0016] The wire receiving section can be connected to the received wire in a force-fitting manner, in particular in a form-fitting manner. In addition or as an alternative, the wire receiving section does not need to be connected to the received wire in a materially fused manner.

[0017] The line receiving section can be designed as a release aid or as a disassembly aid.

[0018] The cable receiving section can have a strain relief device for the received cables.

[0019] The plug connector can be constructed as an integral or one-piece structure. As a result, the plug connector can be quite strong, which is different from multi-component plug connectors in particular, which may disintegrate over time due to permanent vibration loads.

[0020] The plug connector can be partially or completely made of conductive material. The plug connector can be made of steel, tin-plated steel, nickel-plated steel, nickel-plated bronze, tin-plated bronze, brass and / or tin-plated brass in particular. As a supplement or alternative, the plug connector can be constructed for a current of at least 5 milliamperes (mA), in particular at least 10mA and / or at most 100mA, in particular at most 50mA, in particular 20mA. In addition, as a supplement or alternative, the plug connector can be constructed for a voltage of at least 5 volts (V), in particular at least 10V and / or at most 100V, in particular at most 50V, in particular 25V. In addition, as a supplement or alternative, the plug connector, in particular the plug-in sheet receiving section, can be constructed for a transition resistance of at most 3 ohms (Ω), in particular at most 300 milliohms (mΩ), in particular at most 30mΩ, in particular at most 3mΩ with the received plug-in sheet.

[0021] In a development of the invention, the flat clamping arms and the edge guide wings are arranged relative to one another in such a way that a wing spacing direction, in particular a wing spacing, runs non-parallel to, in particular orthogonally to, a wing spacing direction, in particular a wing spacing.

[0022] Additionally or alternatively, the first flat clamping arm, the first edge guide wing, the second flat clamping arm and the second edge guide wing are arranged in this order around the connector receiving direction.

[0023] This, in particular the non-parallel orientation and / or the sequence, enables the edge guide wings to provide lateral support, in particular in the direction of the wing spacing, so that the plug-in plate receiving section cannot slide off the received plug-in plate to one side, in particular in the direction of the wing spacing. As a supplement or alternative, this, in particular the non-parallel orientation and / or the sequence, enables the plug-in plate receiving section to be centered on the plug-in plate.

[0024] In particular, the flat clamping arms and the edge guide wings can describe a rectangular shape. As a supplement or alternative, the plug-in web receiving direction can extend non-parallel to, in particular orthogonally to, the wing spacing direction and / or the arm spacing direction.

[0025] In a development of the invention, the first edge guide wing is directly connected mechanically, in particular electrically, either to the first flat clamping arm or to the second flat clamping arm.

[0026] Additionally or alternatively, the second edge guide wing is directly connected mechanically, in particular electrically, either to the first or to the second flat clamping arm.

[0027] This allows for a relatively simple design and / or relatively simple production of the plug-in connector, in particular of the plug-in lug receiving section.

[0028] In a development of the invention, the edge guide wing extends from the first flat clamping arm in the direction of the second flat clamping arm, in particular in the direction of the arm spacing thereof, in particular all the way to the second flat clamping arm.

[0029] Additionally or alternatively, the edge guide wings can be arranged in a central region of the flat clamping arm, in particular in the direction of receiving the plug lugs.

[0030] Furthermore, as a supplement or as an alternative, the edge guide wings can be as long or as high as a maximum of 50%, in particular a maximum of 40%, of the flat clamping arms in the receiving direction of the plug-in web.

[0031] This, in particular the extension, enables the edge guide wings to provide lateral support, in particular in the direction of the wing spacing, so that the plug-in plate receiving section cannot slide off the received plug-in plate towards one side, in particular in the direction of the wing spacing. As a supplement or alternative, this, in particular the extension, enables the plug-in plate receiving section to be centered on the plug-in plate.

[0032] This, in particular the arrangement and / or the length, allows for relatively easy and / or material-saving production of the plug-in connector, in particular of the lug receiving section.

[0033] In particular, the plug-in plate receiving section can be constructed to plastically expand the wing spacing in the area of ​​the second flat clamping arm. As a supplement or alternative, "arranged in the middle area" can mean that the edge guide wings can be arranged spaced apart from the ends of the flat clamping arm along and / or opposite to the plug-in plate receiving direction. In addition, as a supplement or alternative, the plug-in plate receiving section can be constructed to elastically expand the wing spacing in the middle area. In addition, as a supplement or alternative, the edge guide wings can be as long as a minimum of 5%, in particular a minimum of 10%, in particular 20% of the flat clamping arm along the plug-in plate receiving direction.

[0034] In a development of the invention, the edge guide wings are at least 1 millimeter (mm) and / or at most 4 mm, in particular 2.5 mm long or high, in particular in the receiving direction of the plug tab.

[0035] Additionally or alternatively, the flat clamping arm is at least 3 mm and / or at most 9 mm, in particular 6 mm long or high, in the receiving direction of the plug-in web.

[0036] Furthermore, as a supplement or as an alternative, the arm spacing, in particular in the case of a receiving plug, is at least 1 mm and / or at most 3 mm, in particular 2 mm.

[0037] Furthermore, as a supplement or as an alternative, the wing spacing, in particular in the case of a receiving plug, is a minimum of 3 mm and / or a maximum of 7 mm, in particular 5 mm.

[0038] Furthermore, in addition or as an alternative, the arm spacing, in particular in the case of receiving a plug lug, can be as large as a maximum of 50%, in particular a maximum of 40%, of the wing spacing.

[0039] Furthermore, as a supplement or as an alternative, the flat clamping arms and / or the edge guide wings are at least 0.25 mm and / or at most 0.75 mm, in particular 0.5 mm thick.

[0040] The dimensions enable a better compromise between the magnitude of the force for receiving and the magnitude of the force for releasing. As a supplement or alternative, the dimensions enable a relatively large flat clamping arm to produce relatively low stresses and relatively high clamping or contact forces.

[0041] In particular, the arm spacing can be 0 mm before the plug-in piece is received for the first time in the plug-in piece receiving section, or the free end of the first flat clamping arm and / or the second flat clamping arm can be in contact with another flat clamping arm. As a supplement or alternative, the arm spacing, in particular when receiving the plug-in piece, can be as large as a minimum of 5%, in particular a minimum of 10%, in particular a minimum of 20% of the wing spacing. In addition, as a supplement or alternative, the width of the edge guide wing, in particular along the direction of the arm spacing, in particular when receiving the plug-in piece, can correspond to, in particular be equal to, the arm spacing. In addition, as a supplement or alternative, the width of the flat clamping arm, in particular along the direction of the wing spacing, can correspond to, in particular be equal to, the wing spacing.

[0042] In a refinement of the present invention, the plug connector, in particular the plug-in receiving section, has an insertion limiting section and / or a user squeezing section in the end region of the flat clamping arm along the direction in which the plug-in is received. The insertion limiting section and / or the user squeezing section are constructed or configured to limit the reception of the plug-in sheet, in particular by means of contact with the plug-in sheet, in particular in a form-fitting manner, and / or to squeeze the plug-in receiving section onto the plug-in sheet in a manner that the user can manipulate. This enables the plug-in receiving section to be installed on the plug-in sheet quite easily, in particular without tools, in particular by hand. In particular, the end region can be different and / or spaced apart from the free ends of the first flat clamping arm and / or the second flat clamping arm. As a supplement or alternative, the insertion limiting section and / or the user squeezing section can be constructed to make electrical contact with the received plug-in sheet. Furthermore, as a supplement or alternative, the insertion limiting section and / or the user pressing section can extend non-parallel to, in particular orthogonally to, the plug-in receiving direction and / or parallel to the arm spacing direction and / or the wing spacing direction.

[0043] In one embodiment of the invention, the flat clamping arms are mechanically and in particular electrically connected to one another by means of an insertion limiting section and / or a user pressure section.

[0044] Additionally or alternatively, the insertion limiting section and / or the user pressing section is curved or recessed inwardly, in particular convexly inwardly and / or concavely outwardly or counter to the receiving direction of the plug-in tab.

[0045] This, in particular the connection, allows for a relatively simple design and / or relatively simple production of the plug-in connector, in particular the plug-in lug receiving section.

[0046] This, in particular the curvature, allows the arm spacing to be 0 mm before the plug-in lug is received for the first time in the plug-in lug receiving section or the free ends of the first and / or second clamping arm to contact the other clamping arm.

[0047] In particular, the flat clamping arms do not need to be mechanically connected to one another by means of edge guide wings. Additionally or alternatively, the plug-in lug receiving section does not need to be designed for elastically enlarging the arm spacing in the end region.

[0048] In a development of the invention, the first flat clamping arm and / or the second flat clamping arm is formed in an inclined manner in an arm insertion region for a plug-in lug to be received, in particular, for interaction with the plug-in lug in order to elastically expand the arm spacing.

[0049] As a supplement or alternative, the first edge guide wing and / or the second edge guide wing are particularly obliquely shaped in the wing insertion area for the plug-in tab in order to interact with the plug-in tab to be received, in particular, so as to plastically expand the wing spacing. In particular, the first edge guide wing and / or the second edge guide wing have an introduction chamfer.

[0050] This, in particular the shape of the first flat clamping arm and / or the second flat clamping arm, makes it possible to avoid tilting when receiving the plug-in lug in the plug-in lug receiving section and thus to achieve relatively easy reception.

[0051] In particular, the arm insertion region can be located at the free end of the first flat clamping arm and / or the second flat clamping arm. As a supplement or alternative, the free end of the first flat clamping arm and / or the second flat clamping arm can be bent outward. Furthermore, as a supplement or alternative, the first flat clamping arm and / or the second flat clamping arm can be formed obliquely to the receiving direction of the plug-in piece in the arm insertion region. Furthermore, as a supplement or alternative, the first edge guide wing and / or the second edge guide wing can be formed obliquely to the receiving direction of the plug-in piece in the wing insertion region.

[0052] In a further development of the invention, the wire receiving section is arranged either in particular along the receiving direction of the plug tab at the height of the first flat clamping arm and / or the second flat clamping arm for the plug tab, in particular the arm insertion region, or is arranged in the opposite direction to the receiving direction of the plug tab at a distance from the arm insertion region. This allows a particularly good arrangement of the received wire, in particular the center of gravity of the wire, and thus allows a very good fixation of the received plug tab to prevent it from coming loose from the plug tab receiving section, in particular when the wire vibrates.

[0053] In a further development of the invention, the edge guide wing is directly mechanically and especially electrically connected to the first flat clamping arm. The second flat clamping arm is mechanically and especially electrically connected to the cable receiving section by means of the first flat clamping arm. This allows a very central arrangement of the components of the plug connector, in particular starting from the first flat clamping arm, and thus a very good fixation of the received plug-in connector to prevent it from coming loose from the plug-in connector receiving section.

[0054] In a further development of the present invention, the plug-in plate receiving section, in particular the first flat clamping arm or the second flat clamping arm, and the wire receiving section are mechanically and especially electrically connected to each other by means of a particularly bent spring section. This can reduce or even avoid the transmission of vibrations (if any) of the received wire to the plug-in plate receiving section, and thus can achieve a fairly good fixation of the received plug-in plate to prevent loosening from the plug-in plate receiving section. As a supplementary solution or alternative, this can reduce or even avoid the risk of fracture of the received wire at the wire receiving section. In particular, the wire receiving section can be bent out from the plug-in plate receiving section by means of a spring section, in particular in the opposite direction of the arm spacing direction.

[0055] In a further development of the invention, the connector receiving section and the wire receiving section are arranged relative to one another in such a way that the wire receiving direction extends non-parallel to, in particular orthogonally to, the connector receiving direction, in particular parallel to the wing spacing direction. This can reduce or even prevent the transmission of vibrations (if any) of the received wire to the connector receiving section and thereby enable a relatively good fixation of the received connector to prevent it from coming loose from the connector receiving section. In particular, the wire receiving direction can be parallel to the longitudinal axis of the received wire.

[0056] In a further development of the invention, the wire receiving section is constructed or configured for crimping with the wire, in particular a B-type crimping and / or a lap-crimping. In particular, unlike rolling crimping, the crimping, in particular the B-type crimping, can be processed relatively easily and / or can crimp two wires.

[0057] In a development of the invention, the plug-in connector has a punched and bent part, in particular a punched and bent part, in particular without a welded connection. This allows for relatively easy and thus relatively cost-effective production of the plug-in connector.

[0058] The motor-driven gardening and / or forestry tool according to the invention has a plug-in connector, an electrical line and a plug-in connector as described above. The plug-in connector electrically connects the plug-in connector, which is received in particular, to the electrical line, which is received in particular.

[0059] In particular, the plug strip can be designed as described above. In addition or as an alternative, the electrical line can be designed as described above. Furthermore, in addition or as an alternative, the motor-driven gardening and / or forestry tool can be designed as described above.

[0060] The motor-driven gardening and / or forestry working tool can have an in particular electrical and / or proximity-controlled motor controller, which in particular has an ignition module. The motor controller, in particular the ignition module, can have the plug lug.

[0061] The gardening and / or forestry tool can be a hand-operated, in particular hand-held or ground-guided gardening and / or forestry tool. In particular, a hand-operated, in particular hand-held gardening and / or forestry tool can mean that the gardening and / or forestry tool can have a mass of at most 50 kilograms (kg), in particular at most 20 kg, in particular at most 10 kg.

[0062] The gardening and / or forestry working tool can be a saw, a high-level delimbing machine, a brush cutter, garden shears, shrubbery shears, a blower, a leaf blower, pruning shears, a cutter, a sweeper, a sweeping roller, a sweeping brush, a lawn mower, a scarifier or grass shears.
