Abstract
The utility model relates to a commutator segment of a plug sheet type commutator, which comprises a conducting strip (1) provided with a working surface (11) and a non-working surface (12), and fixed pins (2) connected with the conducting strip; the commutator is characterized in that two fixed pins (2) are arranged and oppositely arranged on both sides of the axis of the non-working surface (12) of the conducting strip (1); a dovetail groove (3) is formed between the inner sides of the two fixed pins (2) and the non-working surface of the conducting strip (1). In the commutator segment, two fixed pins are adopted to form the dovetail groove, to ensure the installation stability of the commutator segment; using the double-fixed pin commutator segment in the commutator with quite large outer diameter and quite a small number can prevent the commutator segment from inclining, carbon brush wear produced by the inclination of the commutator segment, so as to prolong the service life of the commutator.
Description
Technical field
The utility model relates to a kind of commutator segment of engine commutator, particularly a kind of commutator segment structure of blade inserting commutator.
Background technology
Commutator segment is one of vitals of engine commutator, and it can be connected with motor coil, guarantees the continuous rotation of motor.For common blade inserting commutator, the design of its commutator segment generally all is a strip structure, commutator producer generally has only a fixing feet when the design commutator segment, promptly be exposed to the conducting strip outside the commutator plastic and embed the interior fixing feet of commutator plastic to be positioned at a plane substantially.
As the patent No. is that 200620070423.1 " bimetallic commutator segments " disclose a kind of bimetallic commutator segment, comprise active section that exposes outside the bakelite main body and the fixing feet that stretches in the bakelite main body, described commutator segment has two part formation up and down, and the latter half comprises fixing feet at least.This patent has been saved the copper resource from material, reduced cost, but on structure, still adopt traditional strip structure, if the commutator segment of this structure is used in outside diameter big (such as 20mm) in the fewer commutator of sheet number, because have only the fixing feet of a sheet, in should fixing fluctuateed under the high rotating speed of commutator easily in the both sides of pin, will produce the phenomenon that commutator segment tilts in the actual use, cause the aggravation abrasion of carbon brush, shorten the useful life of commutator.Therefore, await to make further improvement.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of fixation at above-mentioned prior art present situation and the commutator segment of the blade inserting commutator that can prevent to tilt, and this commutator segment is particularly suitable for being applied in outside diameter is big and the sheet number the is less commutator product.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: the commutator segment of this blade inserting commutator, comprise have working face, the conducting strip of non-working surface, and be connected fixing feet on this conducting strip, it is characterized in that: described fixing feet has two, and relatively be arranged on axis both sides on this conducting strip non-working surface, form a dovetail groove between the non-working surface of inboard and this conducting strip of described two fixing feet.
In order to reduce the distortion of fixing feet, make commutator segment can better hook phenolic moulding powder by fixing feet when mounted, described each fixing feet bottom also is provided with the hook pin in lateral direction.
In order to simplify the design difficulty of punch die, guarantee the disposable commutator segment of going out requirement, the face width of described hook pin thickness and described conducting strip is identical.
Compared with prior art, advantage of the present utility model is: the commutator segment of this patent has adopted two fixing feet to form an oat tail groove structure, can guarantee the stability when commutator segment is installed, big at external diameter and use the commutator segment of this pair fixing feet can prevent the inclination of commutator segment in the middle of the commutator that the sheet number is less, and the carbon brush wearing and tearing that bring because of the inclination of commutator segment, thereby prolonged useful life of commutator.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the commutator segment structural representation of prior art.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 3, used commutator segment structure in the blade inserting commutator for prior art, this commutator segment comprise conducting strip 1 ' and independent fixing feet 2 that is arranged on this conducting strip 1 ' bottom ', because this commutator segment have only a fixing feet 2 ', when the commutator segment number of installing on the commutator is less, conducting strip is run-off the straight easily just, very easily causes the carbon brush wearing and tearing in the commutator course of work.
As shown in Figure 1 and Figure 2, then be the commutator segment structural representation of the blade inserting commutator after making improvement on the prior art basis.This commutator segment comprises having working face 11, the conducting strip 1 of non-working surface 12, and be connected two fixing feet 2 on this conducting strip 1, wherein, described fixing feet 2 relatively is arranged on the axis both sides on this conducting strip 1 non-working surface 12 respectively, these two fixing feet 2 are oppositely arranged and are certain gradient, 12 of the non-working surfaces of the inboard of two fixing feet 2 and conducting strip 1 form a dovetail groove 3, such design can allow commutator modification not under high speed, solved at the few especially commutator of sheet number under normal operative condition, the problem that commutator segment easily tilts, the useful life of having improved commutator;
Simultaneously, each fixing feet 2 bottom also is provided with direction hook pin 21 outwardly in lateral direction, and these hook pin 21 structures can guarantee that fixing feet 2 hooks phenolic moulding powder, reduces modification, makes commutator segment be firmly fixed in the phenolic moulding powder; In order to simplify the design difficulty of punch die, also working face 11 width of commutator segment are designed to and being of uniform thickness of hook pin 21, so,, just can disposablely go out the commutator segment of requirement by adopting very easy punch die structure.
Claims (3)
1, a kind of commutator segment of blade inserting commutator, the conducting strip (1) that comprises have working face (11), non-working surface (12), and be connected fixing feet (2) on this conducting strip, it is characterized in that: described fixing feet (2) has two, and relatively be arranged on axis both sides on this conducting strip (1) non-working surface (12), a formation dovetail groove (3) between the non-working surface of inboard and this conducting strip (1) of described two fixing feet (2).
2, the commutator segment of blade inserting commutator according to claim 1 is characterized in that: described each fixing feet (2) bottom also is provided with hook pin (21) in lateral direction.
3, the commutator segment of blade inserting commutator according to claim 2 is characterized in that: working face (11) width of described hook pin (21) thickness and described conducting strip (1) is identical.
