Abstract
The utility model discloses a commutator copper sheet of a slot commutator. The commutator copper sheet comprises an implanted part with a dovetail and is characterized in that a through hole is arranged on the side surface of the implanted part; and a groove is arranged on the side surface of the dovetail of the implanted part. The commutator copper sheet with the structure is material-saving and has low cost. After the commutator copper sheet is implanted into a commutator die body, the connecting strength between the commutator copper sheet and the die body is higher. The quality of the slot commutator is effectively improved.
Description
Technical field
The utility model relates to a kind of commutator, what be specifically related to is a kind of switching-over copper sheet of tank commutator.
Background technology
Commutator generally is divided into three kinds of hook commutator, tank commutator and end commutators, traditional tank commutator, and the implantation portion of its switching-over copper sheet is general, and what adopt is the structure of the band dovetail of entity; The switching-over copper sheet is implanted the die body of commutator through implantation portion; Both bonding strengths a little less than, switching-over copper sheet comes off easily in some workplaces, directly influences the commutator product quality; And the switching-over copper sheet materials of entity dovetail structure are many, and production cost is high.
Summary of the invention
In view of the problem that present known technology exists, the technical problem that the utility model will solve is to be to provide a kind of materials cost-saving low, with the switching-over copper sheet of the high tank commutator of die body bonding strength.
The utility model takes following technical scheme to accomplish:
The switching-over copper sheet of tank commutator comprises the implantation portion with dovetail, and it is characterized in that: the side of implantation portion is provided with through hole.The dovetail side of implantation portion is provided with groove.
The beneficial effect of the utility model is: the side of the implantation portion of switching-over copper sheet is provided with through hole, and it not only plays the effect of material-saving, and through it; When the switching-over copper sheet is implanted die body; Full die body material also can be filled in described through hole inside, so combining between switching-over copper sheet and the die body will be more firm, bonding strength is higher; Switching-over copper sheet difficult drop-off during work has improved the product quality of tank commutator; In addition, the dovetail side of implantation portion is provided with groove, plays the effect of material-saving and reinforcing equally.Thus, the utility model materials cost-saving is low, and the bonding strength with die body behind the switching-over copper sheet implantation commutator die body is higher, effectively improves the quality of tank commutator.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of switching-over copper sheet of the tank commutator of prior art;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of switching-over copper sheet of the tank commutator of the utility model;
Fig. 4 be Fig. 3 vertical view.
Embodiment
With reference to accompanying drawing 1,2, the switching-over copper sheet 1 of the tank commutator of prior art comprises the implantation portion with dovetail 2, and implantation portion is the structure of entity.
With reference to accompanying drawing 3,4; The switching-over copper sheet 3 of the tank commutator of the utility model comprises the implantation portion with dovetail 4, and the side of implantation portion is provided with microscler through hole 5; The dovetail side of implantation portion is provided with groove 6, groove 6 be provided with direction with the switching-over copper sheet 3 short transverse parallel.
The utility model compared with prior art, implantation portion is provided with through hole, not only plays the material-saving effect; And, combining meeting more firm between switching-over copper sheet and the die body through it, bonding strength is higher; In addition, the dovetail side of implantation portion is provided with groove, plays the effect of material-saving and reinforcing equally.
Claims (2)
1. the switching-over copper sheet of tank commutator comprises the implantation portion with dovetail, and it is characterized in that: the side of implantation portion is provided with through hole.
2. the switching-over copper sheet of tank commutator as claimed in claim 1, it is characterized in that: the dovetail side of implantation portion is provided with groove.
