Abstract
The utility model discloses a groove-type commutator. The groove-type commutator comprises a plastic press-fitting housing and groove-type commutator segments; the commutator segments are uniformly distributed on an outer circle in a circumferential direction of the plastic press-fitting housing; the plastic press-fitting housing is a cylindrical housing; and diameter of an upper joint part of the plastic press-fitting housing and the head parts of the groove-type commutator segments is bigger. The groove-type commutator is characterized in that a circular platform is arranged on the upper end face of the plastic press-fitting housing; end face teeth are arranged on the end face of the circular platform; the number of the end face teeth is the same as that of groove-type commutator segments; and the end face teeth correspond to the groove-type commutator segments one by one. The groove-type commutator has a good-looking appearance and is available for manufacture, and manufacture quality is good.
Description
Technical field
The utility model relates to a kind of commutator, is specifically related to a kind of improvement invention of tank commutator.
Background technology
Commutator is divided into three kinds of Hooked reverser, tank commutator and end commutators, the tradition tank commutator, the upper surface of its plastic pressure injection housing is that concordant (some is provided with round platform after completing, the round platform surface is also concordant), shortcoming is: above-mentioned tank commutator does not have good location in manufacturing process, be unfavorable for making, make quality and deviation easily occurs; In addition, tank commutator, after processing bonding wire groove, does not have the dividing plate setting between adjacent bonding wire groove, quality problems easily occur making yet.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of good looking appearance, to be conducive to make, make the measured tank commutator of matter.
The utility model takes following technical scheme to complete:
A kind of tank commutator, comprise plastic pressure injection housing and grooved commutator segment, the grooved commutator segment arranges at the cylindrical circumference uniform distribution of plastic pressure injection housing, the plastic pressure injection housing is cylindrical housings, the plastic pressure injection housing is larger with the upper diameter that grooved commutator bar slot head part is combined, and it is characterized in that: the upper end of plastic pressure injection housing is provided with round platform, and the round platform end face is provided with end-tooth, the number of teeth of end-tooth is identical with the sheet number of grooved commutator segment, and end-tooth is corresponding one by one with the grooved commutator segment.The outer circular edge of round platform is provided with separator strip, and separator strip is the emitting shape layout in the upper end of plastic pressure injection housing, and the quantity of separator strip is identical with the sheet number of grooved commutator segment, and separator strip is corresponding one by one with the grooved commutator segment.
The tank commutator of said structure; the round platform end face of plastic pressure injection housing is provided with end-tooth; so just make plastic casing can access good location when pressure injection; guarantee the making quality of tank commutator, simultaneously, be provided with separator strip in the outer circular edge of round platform; this separator strip can be effectively to isolating between adjacent bonding wire groove; make the bonding wire groove more convenient when bonding wire, guarantee that quality problems do not appear in commutator when work, guarantee the making quality of tank commutator.Also have, the tank commutator after end-tooth and separator strip is set, good looking appearance, obtain using the welcome of businessman.
As preferably, the shape of cross section of separator strip is triangle.The end-tooth of above-mentioned design and round platform end face forms good collocation, improves the good looking appearance degree of tank commutator.
The accompanying drawing explanation
The utility model has the following drawings:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
With reference to accompanying drawing 1, 2, a kind of tank commutator of the present utility model, comprise that plastic pressure injection housing 1 and grooved commutator segment 2(are provided with 28), grooved commutator segment 2 arranges at the cylindrical circumference uniform distribution of plastic pressure injection housing 1, plastic pressure injection housing 1 is cylindrical housings, plastic pressure injection housing 1 is larger with top 3 diameters that grooved commutator segment 2 trough parts are combined, top 3 end faces of plastic pressure injection housing are provided with round platform 4, round platform 4 end faces are provided with end-tooth 6, the number of teeth of end-tooth 6 identical with the sheet number of grooved commutator segment 2 (being 28 teeth), end-tooth 6 is corresponding one by one with grooved commutator segment 2, at the bottom of the tooth of end-tooth 6 with the sheet of commutator segment 2 in the middle of over against, the outer circular edge of round platform 4 is provided with separator strip 5, separator strip 5 is emitting shape at the top of plastic pressure injection housing 3 end faces and arranges, the quantity of separator strip 5 identical with the sheet number of grooved commutator segment 2 (being 28), separator strip 5 is corresponding one by one with grooved commutator segment 2, the shape of cross section of separator strip 5 is triangle.
