Abstract
The invention discloses a commutator segment. The commutator segment is simple in structure, is convenient to machine, and improves the reliability of connection with bakelite powder. The commutator segment comprises a head part, a neck part and a copper foot, wherein the head part, the neck part and the copper foot are connected to form a body. An outer side surface of the head part is shaped like an arc, and the cross section of the neck part is rectangular. The cross section of the copper foot is square, and two ends of the copper foot are respectively provided with an embedded groove. Two sides of the copper foot are respectively provided with one embedded groove. After bakelite powder is injected, the bakelite powder is well combined with the copper foot, thereby saving a copper material. The embedded grooves can be set into arc-shaped grooves, dovetail grooves or uniform slots, thereby increasing the contact area of bakelite powder, and improving the connection reliability.
Description
Technical field
The present invention relates to household electrical appliance commutator, more particularly in commutator commutator segment improvement.
Background technology
It is round that commutator is in structure that several contact chips are surrounded, and connects each tap on rotor respectively, and outside connects two electrodes and is referred to as brush and contacts, while only contacting two therein.Principle is：When coil is after electric current, meeting existsPermanent magnetIn the presence of, by attract and repulsive force rotate, when it go to andMagnetDuring balance, the contact led to originally on the relatively corresponding commutator of line of electricity is just separated with brush, and brush is connected to and meets on the corresponding contact of that group of coil for producing motive force, so ceaselessly repeats down, and dc motor is just turned over.
Commutator segment interval setting in a ring, needs that phenolic moulding powder pressure injection is entered, however, commutator segment of the prior art is as shown in figure 5, copper pin is square so that phenolic moulding powder is poor with the associativity of commutator segment, reduces the reliability of work in commutator.
The content of the invention
The present invention is directed to problem above, there is provided a kind of simple structure, convenient processing, improves the commutator segment with phenolic moulding powder connection reliability.
The technical scheme is that：Including the head, neck and copper pin that are connected as a single entity, the lateral surface of the head is in circular arc, and the cross section of the neck is rectangle, and the cross section of the copper pin is square, and the copper pin is respectively arranged at two ends with embeded slot.
The embeded slot is arc groove.
The embeded slot is dovetail groove.
The embeded slot is uniform slot.
In the embeded slot that is respectively provided on two sides with of copper pin, after phenolic moulding powder injection, phenolic moulding powder and copper pin are preferably combined the present invention, and save copper material consumption.Embeded slot can be set to arc groove, dovetail groove or uniform slot, increased the contact area with phenolic moulding powder, improve the reliability of connection.

Specific embodiment
As Figure 1-4, including the head 1, neck 2 and copper pin 3 that are connected as a single entity, the lateral surface of the head is in circular arc to the present invention, and the cross section of the neck is rectangle, and the cross section of the copper pin is square, and the copper pin is respectively arranged at two ends with embeded slot.
As shown in figure 1, the embeded slot is arc groove 4, increase the contact area with phenolic moulding powder, convenient processing, with reference to reliability.
As shown in Fig. 2 the embeded slot is dovetail groove 5, increase the contact area with phenolic moulding powder, convenient processing, with reference to reliability.
As shown in figure 3, the embeded slot is uniform slot 6, increase the contact area with phenolic moulding powder, convenient processing, with reference to reliability.
As shown in figure 4, in production and processing, commutator segment interval is arranged in a ring, and between some commutator segments, the copper pin on commutator segment opens up embeded slot to the pressure injection of phenolic moulding powder 7, improves the reliability being connected with phenolic moulding powder.
