Being includes transverse part, longitudinal direction portion and hook portion, can in advance be snapped onto each contact on hollow reversing shaft by its hook portion；Cause
This as long as positioning by mold to line shaft, while passing through mold to hollow reversing shaft after snapping and more in production
A contact is positioned, so that it may it is molded, after injection molding, boss and turntable are integrally formed, and line shaft is embedded into boss,
Hollow reversing shaft is embedded on turntable, and the transverse part of each contact is embedded on turntable in corresponding contact locating slot, is being molded
The insertion (connection) that line shaft, hollow reversing shaft, each contact are completed while turntable and boss is that boss and turntable are logical
The mode for crossing injection molding is integrally formed, and line shaft, hollow reversing shaft, each contact are embedded into corresponding position in injection molding,
Without other assembly process, commutator is realized by being integrally formed, production process is greatly reduced, reduction is produced into
This.
As a preferred embodiment of the present invention, the part that the line shaft is embedded into the boss is equipped at least two
Groove.By the way that at least two grooves are arranged on line shaft, when being molded boss and turntable, the plastics of boss are squeezed into recessed automatically
Fixture block is formed in slot, by line shaft clamping.
As the further preferred embodiment of the utility model, each groove is staggered in the axial direction of the line shaft to be set
It sets.
As a preferred embodiment of the present invention, the contact is silver-colored contact.
The utility model compared with prior art, has the advantages that
Boss is added by the first end face in turntable, sets hollow reversing shaft for reversing shaft, and sets contact to
Including transverse part, longitudinal direction portion and hook portion, each contact is snapped on hollow reversing shaft by its hook portion in advance, boss and turntable
It is integrally formed by way of injection molding and line shaft, hollow reversing shaft, each contact is embedded into corresponding position, without in addition
Assembly process, realize commutator by being integrally formed, be greatly reduced production process, reduce production cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the preferred embodiments of the present invention.
Specific embodiment
It is described further with reference to the accompanying drawing with preferred embodiments of the present invention.
As shown in Figure 1, the integrated combination commutator of this micro machine, including line shaft 1, turntable 2, hollow reversing shaft 3,
Multiple silver contacts 4 and boss 5；Boss 5 is arranged in the first end face of turntable 2, and one end of line shaft 1 is embedded into boss 5, moves
Power axis 1, which is embedded on the part of boss 5, to be set there are two groove 6, and two grooves 6 are arranged in a staggered manner in the axial direction of line shaft 1；It is hollow
One end of reversing shaft 3 is embedded into the second end face of turntable 2；The second end face of turntable 2 is equipped with a plurality of contact locating slot 7, respectively
Contact locating slot 7 is starting point with hollow reversing shaft 3 and radially outwardly extending；Silver-colored contact 4 includes being connected in turn
