Abstract
The utility model discloses splicing type commutator, comprise by the commutation matrix of phenolic moulding powder material compacting and the commutation copper sheet in the even screening of commutation matrix excircle, it is characterized in that: described commutation copper sheet comprises main leaf body and is located at two fixing feet up and down of main leaf body medial surface, the top connecting cylinder shape contact pin of described main leaf body, upper and lower two fixing feet are implanted in commutation matrix and commutation matrix strong bonded, the centre of described main leaf body is provided with upper and lower two hollow out die cavities along main leaf body short transverse, upper and lower hollow out die cavity is corresponding with upper and lower fixing feet respectively, hollow out die cavity is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening carry out outward running through from the medial surface of main leaf body and pass through in the middle of corresponding fixing feet, phenolic moulding powder material and commutation matrix strong bonded is filled in described hollow out die cavity.The utility model can realize grafting and use, and improves ease of use, can possess stronger hypervelocity performance simultaneously.
Description
Technical field
The utility model relates to commutator topology field, is specifically related to a kind of splicing type commutator.
Background technology
Commutator is mainly widely applied in electric tool, and commutator is installed and used in process after completing, and is all be welded to connect by the connector lug of welding manner and motor coil, uses often very inconvenient, in addition, hypervelocity performance weighs an important technology index of commutator quality, and the hypervelocity performance of commutator will be improved, first want it is considered that strengthen commutator shaping time commutation copper sheet and phenolic moulding powder between adhesion, and this is generally the structure of the fixing feet by improving commutation copper sheet, quantity realizes, because the main leaf body of each commutation copper sheet when commutator is shaping very near and and there is no favourable impetus between phenolic moulding powder, so all the time, whom various equivalent modifications do not have can consider to strengthen adhesion between commutation copper sheet and phenolic moulding powder by the architecture advances of main leaf body, therefore the hypervelocity performance of commutator can not improve to a certain extent further, better can not meet the more and more higher rate request of electric tool.
Summary of the invention
In view of the deficiency of background technology, the purpose of this utility model aims to provide one can realize grafting use, improves ease of use, can possess the splicing type commutator of the performance that exceeds the speed limit more by force simultaneously.
The utility model is implemented by the following technical programs:
Splicing type commutator, comprise by the commutation matrix of phenolic moulding powder material compacting and the commutation copper sheet in the even screening of commutation matrix excircle, it is characterized in that: described commutation copper sheet comprises main leaf body and is located at two fixing feet up and down of main leaf body medial surface, the top connecting cylinder shape contact pin of described main leaf body, upper and lower two fixing feet are implanted in commutation matrix and commutation matrix strong bonded, the centre of described main leaf body is provided with upper and lower two hollow out die cavities along main leaf body short transverse, upper and lower hollow out die cavity is corresponding with upper and lower fixing feet respectively, hollow out die cavity is provided with left and right opening to be run through outward from the left and right side of main leaf body, be provided with interior side opening carry out outward running through from the medial surface of main leaf body and pass through in the middle of corresponding fixing feet, phenolic moulding powder material and commutation matrix strong bonded is filled in described hollow out die cavity.
Described cylinder type contact pin is positioned at top straight forming after size reduces of commutator upper surface by commutation copper sheet.
The splicing type commutator of technique scheme, first, every commutation copper sheet is all provided with a cylinder type contact pin, as long as arrange the socket of coupling again, so just can realize the inserting function of commutator, avoid the loaded down with trivial details of bonding wire, thus greatly can improve the ease of use of commutator, also have, the splicing type commutator of technique scheme unlike the prior art, it by the architecture advances of the main leaf body to commutation copper sheet strengthen commutator shaping time and phenolic moulding powder between adhesion, namely hollow out die cavity is set in the centre of main leaf body, and hollow out die cavity is provided with left and right opening and interior side opening, when enabling commutator shaping, phenolic moulding powder is fully filled to enter in hollow out die cavity and formed between the main leaf body of commutation copper sheet and is firmly combined, the setting of hollow out die cavity simultaneously reduces the weight of commutation copper sheet self, due to the enhancing of adhesion and alleviating of weight, thus effectively improve the hypervelocity performance of commutator, the hypervelocity performance of commutator is further enhanced on the basis of existing technology, thus better meet the more and more higher rate request of electric tool.
Accompanying drawing explanation
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in the figure, splicing type commutator of the present utility model, comprise by the commutation matrix 6 of phenolic moulding powder material compacting and the commutation copper sheet in the even screening of commutation matrix 6 excircle, described commutation copper sheet comprises main leaf body 2 and is located at two fixing feet 5 up and down of main leaf body 2 medial surface, the top connecting cylinder shape contact pin 1 of described main leaf body 2, described cylinder type contact pin 1 is positioned at top straight forming after size reduces of commutator upper surface by commutation copper sheet, upper and lower two fixing feet 5 are implanted in commutation matrix 6 and commutation matrix 6 strong bonded, the centre of described main leaf body 2 is provided with upper and lower two hollow out die cavities 3 along main leaf body short transverse, upper and lower hollow out die cavity 3 is corresponding with upper and lower fixing feet 5 respectively, hollow out die cavity 3 is provided with left and right opening to be run through outward from the left and right side of main leaf body 2, be provided with interior side opening 4 carry out outward running through from the medial surface of main leaf body 2 and pass through in the middle of corresponding fixing feet 5, phenolic moulding powder material and commutation matrix 6 strong bonded is filled in described hollow out die cavity 3.
