Definitions

  • the invention relates to a working device with a strain relief for a connection cable.
  • a connector In implements with electric drive usually a connector is provided, which can be arranged on a short cable section and to which a connection cable can be connected. During operation, tensile forces can act on the connection between the two cables which lead to the connection being released. To avoid this, strain reliefs for connection cables are known which absorb tensile forces during operation and thus prevent tensile forces acting on the connection.
  • holding stubs are known, around which a connecting cable can be looped.
  • the connecting cable can be held on the holding stub by clamping or by friction.
  • the stub In order to prevent the connecting cable from slipping off the holding stub when it is not loaded, the stub must be adapted to the diameter of the connecting cable.
  • the invention has for its object to provide an implement with a strain relief for a connection cable, in which the strain relief for connection cable of different diameters is suitable and has a simple structure.
  • the securing element ensures that the connection cable can not come loose from the holding connection, in particular when no tensile forces act on the connection cable. A clamping of the connecting cable to the holding pipe is therefore not necessary.
  • connecting cables of different diameters can be arranged on the holding stub.
  • the receptacle extends advantageous at least over half the outer circumference of the holding neck.
  • the holding neck of the connecting cable is looped over a circumferential angle of at least 180 °.
  • a fixation of the connecting cable is made possible by friction on the holding stub. The tensile forces occurring during operation on the connection cable are thereby completely absorbed by the holding connection.
  • the securing element merely prevents the connection cable from slipping off the holding stub.
  • This can be simple and have a low weight, so that the weight of the working device is not significantly increased by the securing element.
  • the securing element rests against the outside of the connecting piece on the connection cable.
  • the fuse element acts in the usual working posture of the implement from below against the connecting cable and thus counteracts gravity.
  • a simple design results when the fuse element has a holding plate, which rests against the connecting cable.
  • the holding plate advantageously has a receiving trough for the connecting cable. As a result, the position of the connection cable, in particular for connection cables with a reduced diameter, defined by the holding plate.
  • the securing element is pivotally mounted.
  • it can be ensured in a simple manner with connecting cables of different diameters that the securing element always bears against the connecting cable.
  • the securing element In order to fix the connection cable to the holding stub, only the securing element has to be pivoted away. This results in a simple operation.
  • a simple design of the securing element results when the securing element is formed integrally with at least one bearing journal, with which the securing element is pivotally mounted in a housing of the working device. For storage of the fuse element thereby no additional components are needed. This results in a simple structure.
  • the securing element is spring-mounted.
  • the fuse element does not have to be pressed by the operator against the connection cable but due to the suspension automatically gets into the position of attachment on the connection cable.
  • the securing element is formed integrally with a spring section.
  • additional suspension elements can be omitted.
  • the spring portion is formed as a spring bar, which projects into a housing of the implement and which is supported in the housing. The fact that the spring bar is at least partially disposed within the housing of the implement, it is protected from dirt and damage.
  • the spring bar is disposed completely within the housing.
  • a simple design results when the fuse element is made of plastic.
  • the strain relief is arranged in a recess in a housing of the working device.
  • the recess may be formed as a recess in the housing, but advantageously the recess is formed as a breakthrough on the housing, so that the strain relief is accessible from both sides.
  • the direction in which the connection cable is led away from the strain relief can be selected individually by the operator.
  • the holding stub on an end plate which limits the receptacle formed on the outer circumference of the holding neck laterally. As a result, a lateral slipping of the connecting cable is avoided by the holding nozzle in a simple manner and without additional components.
  • connection cable In order to allow easy fixing and detachment of the connection cable to the support stub, it is provided that between the end plate and the wall opposite the end plate the recess is formed an inlet opening for the connecting cable.
  • the connecting cable does not have to be threaded around the retaining neck, but can be guided as a loop through the inlet opening and slipped over the retaining stub.
  • Between the inlet opening and the receptacle formed on the outer circumference of the holding nozzle is advantageously formed at least one passage opening which is at least partially closed by the securing element. The securing element thus prevents the connection cable from inadvertently entering the inlet opening through the passage opening and thus being able to detach from the holding connection.
  • At least one stiffening strut is advantageously arranged on the outer circumference of the holding stub, which extends approximately in the longitudinal direction of the holding stub.
  • the stiffening strut stiffens on the one hand the holding stub, so that larger forces are absorbed. At the same time hinders the stiffening strut, which runs transversely to the recording movement of the connecting cable in its longitudinal direction. As a result, the tensile forces in the connection cable, which can be absorbed by the strain relief, increased.
  • the stiffening strut can also be designed so that it also narrows the receptacle laterally, so that there is a clamping action of the connecting cable to the holding stub.
  • Fig. 1 is shown as an exemplary embodiment of a working device 1, a portable, hand-held blower 1.
  • the blower 1 can be converted into a suction device.
  • the blower 1 has a housing 2, on which an upper handle 3 is fixed.
  • the upper handle 3 is formed on the housing half-shells of the housing 2 and connected via a front connecting portion 35 and a rear connecting portion 36 with the housing 2.
  • a throttle lever 4 for operating a housing 2 arranged in the drive motor 6 is mounted.
  • the drive motor 6 is designed as an electric motor and drives via a drive shaft 7, an impeller 8 rotating.
  • the impeller 8 sucks an intake 9 working air and blows them out through a blowout 10.
  • a blowpipe and at the intake opening 9 a suction grille is set at the exhaust opening. If the blower 1 is to operate as a suction device, then a suction tube is fixed to the suction opening 9 and a collecting bag for sucked-in material is attached to the outlet opening 10.
  • a plurality of cooling air openings 11 are provided on the housing 2.
  • a connection cable 30 is fixed to the housing 2.
  • the connecting cable 30 is connected via a plug-in connection, not shown, with another connecting cable 5.
  • the connection cable 5 is advantageously an extension cable.
  • the connection cable 5 is held on a strain relief 40 on the housing 2.
  • the strain relief 40 serves to absorb 5 acting tensile forces on the connecting cable and not forward to the connector to the connecting cable 30 so as to prevent the connector between the connecting cables 5 and 30 is accidentally released.
  • the strain relief 40 is arranged in a recess 12 in the housing 2, which is designed as a breakthrough in the rear connecting portion 36.
  • the strain relief 40 is thus accessible from both sides of the housing.
  • the strain relief 40 comprises a holding stub 13 which projects transversely to the longitudinal direction of the recess 12 in the recess 12. At the free end of the holding pipe 13 an end plate 14 is arranged, which projects laterally beyond the support stub 13.
  • the strain relief 40 also includes a securing element 15, which rests on the connection cable 5 on the side facing away from the holding stub 13 outside. The securing element 15 protrudes from the bottom, ie from the direction of action 37 of gravity ( Fig. 1 ) down side in the recess 12th
  • a first passage opening 33 is formed on the upper side in the direction of action 37 of gravity, and a second passage opening 34 is formed on the side lying below in the direction of action 37.
  • the two limiting the loop portions of the connection cable 5 can be pushed over the end plate 14 to the support stub 13.
  • a receptacle 28 is formed for the connecting cable 5, which is bounded laterally by the end plate 14.
  • connection cable 5 The distance a between the wall 29 of the recess 12 and the end plate 14 is greater than the diameter d of the connection cable 5, so that the connection cable 5 can be easily inserted through the inlet opening 32.
  • the holding plate 16 has a receiving trough 20 which is rounded and presses against the connecting cable 5.
  • a distance b is formed, which is significantly smaller than the diameter d of the connecting cable 5.
  • the passage opening 34 is largely closed by the securing element 15, so that the connection cable 5 can not pass through the passage opening 34 and can be detached from the holding connection 13.
  • Fig. 3 dashed line connecting cable 5 'is shown on the support stub 13, which has a reduced diameter d'.
  • the securing element 15 pivots further upwards, so that the holding plate 16 'in the in Fig. 3 dashed line position is shown and is applied to the connection cable 5 '.
  • the distance between the end plate 14 and the support plate 16 ' is smaller than the diameter d' of the connecting cable 5 ', so that even with connecting cables 5' with a reduced diameter d 'unintentional release of the connecting cable 5' is avoided by the holding stub 13 ,
  • Fig. 4 shows the design of the securing element 15.
  • the securing element 15 comprises a bearing shaft 17 which is integrally formed on the holding plate 16.
  • bearing pins 18 are integrally formed on both sides, with which the securing element 15 is pivotally mounted in the housing 2 of the blower 1 about a pivot axis 22.
  • the holding plate 16 protrudes through a slot in the housing 2, the housing between two
  • a spring bar 19 is formed, which projects from the bearing shaft 17 downwards and which is arranged completely in the interior of the housing 2.
  • the spring bar 19 is located on the in Fig. 7 shown pin 26 of the housing 2 at.
  • the retaining plate 16 is mounted sprung in the direction of the connection cable 5.
  • the pivot axis 22 of the securing element 15 is aligned parallel to the longitudinal direction of the recess 12 and arranged on the holding stub 13 opposite side of the recess 12 in the interior of the housing 2.
  • the holding pipe 13 is formed on the housing 2 and formed as a hollow cylinder.
  • stiffening struts 21 are arranged, which extend in the longitudinal direction of the holding stub 13 and in the longitudinal direction of the recess 12.
  • the stiffening struts 21 are shown more clearly.
  • the stiffening struts 21 are approximately triangular in shape and thus narrow the receptacle 28 at the bottom of the receptacle 28.
  • the holding stub 13 has on its outer periphery elevations 25, which may have a triangular or a rectangular cross-section.
  • the elevations 25 extend in the longitudinal direction of the holding stub 13 and transversely to the longitudinal direction of the connecting cable 5 and thus improve the fixation of the connecting cable 5 on the holding stub 13.
  • the housing 2 is composed of two housing half-shells 23 and 24, which are divided perpendicular to the pivot axis 22.
  • the holding pipe 13 is half in each case the housing half shells 23 and 24 formed.
  • the securing element 15 is held between the two housing half-shells 23 and 24.
  • the fuse element 15 is advantageously as well as the housing half shells 23 and 24 made of a plastic.
  • the elevations 25 are formed as an extension of the stiffening struts 21.
  • the connection cable 5 wraps around the holding stub 13 by significantly more than half, advantageously by approximately three quarters of its circumference.
  • the connecting cable 5 is thereby held by friction on the support stub 13.
  • With a tensile force at one of the ends of the connecting cable 5 the holding stub 13 is wrapped tightly by the connection cable 5 and the frictional forces occurring prevent slippage of the connection cable 5 on the outer circumference of the holding stub 13.
  • the securing element 15 serves only to secure the connecting cable 5 on the holding stub 13th However, the securing element 15 does not have to absorb tensile forces of the connection cable 5.
  • FIG. 7 shows, the holding stub 13 via a rounding 27 in the holding plate 14 via.
  • the holding plate 14 projects beyond the holding stub 13 and thus limits the receptacle 28 laterally.
  • the connecting cable 30, which is held on the housing 2 is guided at the outlet from the housing 2 in a cable grommet 31.
  • connection cable 5 is looped through the inlet opening 32 and through the passage openings 33 and 34 via the end plate 14 on the Retaining sleeve 13 pushed.
  • the holding plate 16 is pivoted in the direction of the arrow 38 down to release the passage opening 34 for the connection cable 5.
  • a corresponding pivoting of the holding plate 16 is also carried out to release the connecting cable 5.
  • the holding plate 16 is spring-loaded against the connecting cable 5 and holds the connecting cable 5 in operation on the holding stub 13th
  • the receptacle 28 extends over the entire outer circumference of the holding stub 13, so that the connection cable 5 can be pushed from both sides via the holding stub 13 into a portion of the receptacle 28.
