Abstract

A collector ring structure for a vehicle AC generator comprises two copper pre-embedded sheets as lead, two copper collector rings and an injection molding frame, wherein one end of two copper pre-embedded sheets is respectively welded with two copper collector rings; the copper pre-embedded sheets and the copper collector rings are cast together by the injection molding frame and two copper collector rings are insulated from each other. The utility model is characterized in that the other end of two copper pre-embedded sheets are respectively extended outwards from a circular seat on the bottom of the injection molding frame and are coated in the injection molding frame to form two long arms; the ends of the copper pre-embedded sheets are extended from the injection molding frame to integrally form a T-shaped structure. The utility model has the advantages that it simplifies the production process, improves the production efficiency, enhances the firmness of the welding between the rotor excitation coils and the collector rings, prevents the short circuit between the copper wires of the rotor excitation coils and the rotor end face, and prevents the insulating varnish from flowing into the processing surface on the shaft end of the rotor to influence the axial size of the generator.

Description

Vehicle alternator collector ring structure

Technical field

The utility model belongs to a kind of alternator for vehicle parts, particularly a kind of vehicle alternator collector ring structure.

Background technology

The collector ring of existing vehicle alternator is made of lead, current collection copper ring and molded plastic frame etc.One end of lead is connected with the current collection copper ring, and the other end stretches out from the circle seat of molded plastic frame bottom.During assembling, need earlier the rotor magnetizing coil to be fixed on the skeleton both sides, again by being connected with the collector ring lead behind rotor end-face fluting or the rotor end-face.The phenomenon of not generating electricity appears easily that the copper cash of rotor magnetizing coil and rotor end-face are short-circuited and in this structure, insulating varnish flow to the hidden danger of armature spindle two ends machined surface by rotor end-face fluting place when also existing rotor to roll insulating varnish, influences the axial dimension of generator.

Summary of the invention

The purpose of this utility model is to solve the problem that above-mentioned prior art exists, stop the copper cash of rotor magnetizing coil and the phenomenon that rotor end-face is short-circuited, strengthen the fastness of rotor magnetizing coil copper cash and collector ring welding, a kind of vehicle alternator collector ring structure is provided.

The utility model comprises pre-buried of two copper as lead, two current collection copper rings and molded plastic frame, the end that two copper is pre-buried welds together with two current collection copper rings respectively, pre-buried of copper and current collection copper ring are cast in together with molded plastic frame, and make two current collection copper ring mutually insulateds, its special character is, the other end that two copper is pre-buried stretches out from the circle seat of molded plastic frame bottom respectively, and be wrapped in the molded plastic frame, constitute two long-armed, the terminal part that copper is pre-buried stretches out from molded plastic frame, forms T-Type structure on the whole.

Advantage of the present utility model is, pre-buried circle seat from the molded plastic frame bottom of copper on the collector ring stretched out, constitute two long-armed, and form T-Type structure on the whole, when being connected with magnetizing coil, can be directly and lead-out wire be welded together, simplified production technology, improved production efficiency, and strengthened the fastness of rotor magnetizing coil and collector ring welding, stopped the copper cash of rotor magnetizing coil and the phenomenon that rotor end-face is short-circuited, simultaneously, prevented that also insulating varnish from flowing into rotor axle head machined surface and influencing the axial dimension of generator.

Embodiment

As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, the utility model comprises pre-buried 1 of two copper as lead, pre-buried 5, two current

collection copper rings

3,4 of copper and molded plastic frame 2, pre-buried 1 of two copper, an end of 5 weld together with two current

collection copper rings

3,4 respectively, become as a whole; Pre-buried 1 of copper, 5 and current

collection copper ring

3,4 usefulness molded plastic frames 2 be cast in together, and make two current collection copper rings, 3,4 mutually insulateds; Pre-buried 1 of two copper, 5 the other end stretch out from the circle seat of molded plastic frame 2 bottoms respectively, and are wrapped in the molded plastic frame 2, constitute two long-armed, pre-buried 1 of copper, 5 terminal part stretch out from molded plastic frame 2, form T-Type structure on the whole.

As shown in Figure 6 and Figure 7, during assembling, earlier collector ring is press fit on the armature spindle 13 by frock, and collector ring is just touched on the rear solid end utmost point 12, then, fan 6 is welded on the rear solid end utmost point 12, in this process, two long-armed belows that just are fixed on fan 6 of collector ring, it is further fixing that collector ring is obtained; The copper cash of magnetizing coil 10 skeleton 11 9, the 9a place reserves lead-in wire 8,8a through after once twining, with this lead-in wire 8,8a respectively with collector ring on pre-buried 1 of two copper, 5 carry out melting welding, melting welding o'clock 7, the 7a place, the assembly work of collector ring is just all finished.
