Definitions
- the invention relates to an electrical connection device for an electrically conductive brush sleeve receiving a carbon brush, to which the carbon brush is in turn connected in an electrically conductive manner, in which device the brush sleeve is also inserted into a guide shaft of a brush holder assigned to an electrical machine and connected to an electrical feed line in. the insertable contact lug is in electrical connection.
- connection device is known from US Pat. No. 2,748,301.
- the contact lug is inserted laterally from the brush sleeve axially parallel to the latter in the guide shaft.
- a receiving channel is provided in the wall of the guide shaft.
- the contact lug is curved in the longitudinal direction, so that, despite the manufacturing tolerances of the individual parts, the contact lug is surely in contact with the brush sleeve.
- a latching tongue is provided on the guide shaft in a corresponding recess in the wall of the guide shaft.
- the contact tab must be specially designed to ensure its function in the known device, which requires a corresponding manufacturing effort. Because of the limited space, it is difficult to insert the contact tab into the guide shaft.
- the invention is based on the object of designing a connection device of the type described at the outset in such a way that there is no need for a specially adapted shape of the contact tab for reliable contacting between the contact tab and the brush sleeve.
- the object is achieved according to the invention in that the contact lug is inserted through an opening in the wall of the guide shaft and protrudes at least so far into the guide shaft that it is bent when the brush sleeve is inserted into the guide shaft.
- the contact lug can be designed to be completely straight in the original state.
- the contact lug By bending the contact lug when inserting it into the guide shaft, it is ensured that the contact lug always rests on the brush sleeve with a certain pressure, regardless of the dimensional tolerances of the individual parts, so that there is a good electrical connection between the contact lug and the brush sleeve.
- By bending the contact lug inserted through the opening it is also mechanically fixed to the wall of the guide shaft without requiring any special precautions on the contact lug and when mounting it.
- a jamming of the brush sleeve during insertion into the guide shaft is prevented by the opening being followed by a receiving groove extending in the insertion direction of the brush sleeve, the depth of which relative to the guide surface of the relevant wall of the guide shaft is at most equal to the material thickness of the contact tab and its length is at least equal to the length of the bent part of the contact lug.
- the contact lug lies in the receiving channel when it is bent over and thus does not narrow the cross section of the guide shaft.
- connection device results in connection with a universal motor connected in series and inserted in a plastic housing in that the guide shafts are integrally formed on the front side of the plastic housing and the contact lugs are connected to the stator winding of the motor and on which the winding supports of the stator winding support axially are attached above and that the opening for pushing through the contact tab is provided in each case in the wall part of the plastic housing delimiting the guide shaft.
- a brush sleeve 3 is inserted into a guide shaft 2 provided on a brush holder 1.
- the brush sleeve 3 is held in the guide shaft 2 by latching tongues 5 and 6 which are bent out of the wall of the brush sleeve 3 and which latch in a recess 7 provided in the one wall of the guide shaft 2.
- a carbon brush 4 which is pressed by a spring 8 against the collector 9 of an electrical machine.
- the spring 8 is supported at its end opposite the carbon brush 4 on a projection 10 bent out of the wall of the brush sleeve 3.
- the electrical connection of the carbon brush 4 to the brush sleeve 3 can take place via the spring 8 or a separate wire which is connected to the carbon brush 4 and the brush sleeve 3.
- the power supply to the brush sleeve 3 takes place via a contact lug 13 which is inserted through an opening 12 provided in the wall 11 of the brush holder delimiting the guide shaft 2.
- a feed line 14 is connected to this contact tab 13.
- the end 15 of the contact protruding into the guide shaft 2 is ne 13 bent and lies in a receiving groove 16.
- the contact tab 13 is straight in the original state, so that it can be easily inserted through the opening 12.
- Fig. 2 With 17 the stator and 18 the rotor of a universal motor, which is installed in a plastic housing 19.
- two guide shafts 2 are formed, in each of which a brush sleeve 3 is inserted.
- the winding heads 20 of the stator winding are supported by winding supports 21 and 22, respectively.
- Axially projecting contact lugs 23 are fastened to the winding carriers 22 arranged on the collector side of the motor.
- an opening 25 is provided, through which the contact lug 23 connected to the winding carrier 22 is inserted. The contact lug 23 is pushed through the opening 25 when the stand 17 is inserted into the plastic housing 19.
