Abstract
The utility model discloses a reinforced plastic commutator which comprises a commutator segment 1 and a molding compound 2, wherein the foot part 3 of the commutator segment forms a double-dovetail shape, the body part 4 of the commutator segment forms a ladder shape, and the body part 4 is connected with the foot part 3 of the commutator segment to form a T-shaped structure. The utility model solves the problem of small adhesion force between a commutator segment and a molding compound of an original product, effectively eliminates the phenomena of rupture and piece flying of a plastic commutator when a motor works, enhances the mechanical strength of products, reduces waste product rate and enhances the quality of products.
Description
One, technical field
The utility model relates to the overall plastic commutator that a kind of motor is used.
Two, background technology
Existing overall plastic commutator is made of commutator segment and moulding compound, does not have mica sheet between the commutator segment, and the area that contacts between commutator segment and the moulding compound is less, makes that the adhesive force between commutator segment and the moulding compound is less.In motor runs up process overall plastic commutator easily produce break, the film flying phenomenon, had a strong impact on the operate as normal of motor.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and the bigger reinforced overall plastic commutator of contact area between a kind of commutator segment and the moulding compound is provided.
The purpose of this utility model realizes by following technical solution: a kind of reinforced overall plastic commutator, comprise commutator segment, moulding compound, the foot of described commutator segment is two dovetail shapeds, and the body portion of commutator segment is trapezoidal shape, and the body portion of commutator segment be " T " font structure being connected of foot.
After adopting the utility model structure, because the foot of the commutator segment of this commutator and body portion and the profile that is connected thereof have all been carried out innovative design, moulding compound can fully be entered between the commutator segment, thereby increased the contact area between commutator segment and the moulding compound greatly, strengthened the adhesive force between commutator segment and the moulding compound.Therefore, the utility model compared with prior art can effectively be eliminated the breaking of overall plastic commutator, film flying phenomenon, has strengthened the mechanical strength of product, has reduced percent defective, has improved product quality.
Four, description of drawings
Below in conjunction with accompanying drawing and execution mode the utility model is described in further detail.
Fig. 1 is the structural representation (partly) of the reinforced overall plastic commutator of the utility model.
Fig. 2 is the B-B cutaway view of Fig. 1.
Fig. 3 is the structural representation of the commutator segment among Fig. 2.
Fig. 4 is the left view of Fig. 3.
Five, embodiment
Referring to figs. 1 through Fig. 4 as can be known, the reinforced overall plastic commutator of the utility model, comprise commutator segment 1, moulding compound 2, there is not mica sheet between the commutator segment, the foot 3 of described commutator segment is two dovetail shapeds (as Fig. 2, shown in Figure 3), the body portion 4 of commutator segment is trapezoidal shape (as shown in Figure 4), and the body portion 4 of commutator segment be " T " font structure (as shown in Figure 4) being connected of foot 3.
Claims (1)
1, a kind of reinforced overall plastic commutator, comprise commutator segment (1), moulding compound (2), it is characterized in that: the foot of described commutator segment (3) is two dovetail shapeds, and the body portion (4) of commutator segment is trapezoidal shape, and the body portion (4) of commutator segment be " T " font structure being connected of foot (3).
