According to accompanying drawing preferred implementation of the present invention is carried out illustrated in detail below.Wherein:
Fig. 1 is the sketch map of the motor of routine;
Fig. 2 is the perspective view by the brush holder that is used for motor of execution mode of the present invention;
Fig. 3 be by execution mode of the present invention with anti-interference condenser be arranged in the brush holder with and the view of the amplification of the way of contact;
Fig. 4 be by another embodiment of the present invention with anti-interference condenser be arranged in the brush holder with and the view of the amplification of the other way of contact.
Embodiment
Fig. 1 shows the sketch map of the motor 1 with housing 2 and rotor 3, on this rotor, has arranged driving element 4.Stator apparatus 5 is arranged in housing, and this stator apparatus surrounds the driving element 4 of said motor 1 basically, and is arranged on the inboard of said housing 2.
Said driving element 4 has the coil windings (not shown), and this coil windings can be carried out electricity by commutator 6 and triggered.It is neighbouring on the position about said driving element 4 biasings on the rotor 3 that said commutator 6 is located at rotor tip.Be provided with brush holder in order to contact said commutator 6, this brush holder is the housing parts 7 that is used to overlap on the opened end portions that installs to housing 2, and has the brush 8 of the said commutator 6 of contact.Said brush 8 can electrically contact through the electrical interconnection 9 that passes brush holder 7 from the outside.
In Fig. 2, show brush holder 10 in further detail according to a kind of execution mode for such motor.Said brush holder 10 has four brushes 11, and these brushes are electrically connected through the connection line 13 of suitable contact circuit 12 with the guiding outside.Said two connection lines 13 extend to housing 2 inside from housing 2 outsides through the protective sleeve on the brush holder 10 14, and terminate in respectively there on the jockey that clamps fork 15 forms.
Said brush holder 10 has masking material 16, and said connection line 13 passes masking material, thereby the voltage that will be applied on the outer sections of connection line 13 imports enclosure interior.Said connection line 13 is respectively outwardly-bent after it passes masking material 16, makes it be arranged essentially parallel to or the inner surface that favours masking material 16 remotely extends each other.Second section of each connection line 13 comprises and clamps fork 15, said clamping fork basically with the inner surface of masking material 16 at right angles or stretch out obliquely.
According at first execution mode shown in Fig. 3, first joint 20 of each anti-interference condenser 18 for example is connected through clamping with first section of the part that is positioned at housing 2 inside of connection line 13 through melting welding or soldering in other words.
The contact plate 22 that is used to contact housing 2 also can be configured to flexible, thus with this contact plate under the state of housing 2 of packing into towards housing 2 extruding, and be used to improve contact (the so-called ground connection contact) with housing 2 thus.In addition, also can compensate structural detail tolerance and build-up tolerance between said brush holder 10 and housing 2 thus extraly.As the replacement scheme of contact plate 22, point or sharp contact element also can be set, this contact element is realized and the electrically contacting of housing 2 through when pushing brush holder 10, wiping japanning or oxide layer in respective housings 2 off.
