Problems solved by technology

[0003] The existing structure design of the commutator segment is not reasonable enough. On the one hand, when the commutator segment is welded to the winding, it completely relies on the pressure of the hook when it is pressed down and the heat generated during the welding process to melt the outer insulating layer of the winding, so that the winding and the commutator As a result, the effect of the electrical contact between the winding and the commutator is not ideal, which affects the reliability of the motor; on the other hand, when the hook is pressed down by force, the winding will generate a large In the case of poor control, the winding is easily deformed and even broken, which affects the service life of the motor

Embodiment 1

[0044] see figure 1 and figure 2 , in this embodiment 1, the protection structure is a piercing mechanism capable of piercing the outer insulating layer of the winding 7 . Typically, the winding 7 can be enameled wire, for example. Taking the enameled wire as an example, when winding the wire, when the winding 7 is hung on the hook, due to the existence of the piercing mechanism, the paint leather of the contact part between the enameled wire and the commutator segment 2 will be easily pierced by the piercing mechanism, so that the enameled wire and the The commutator segment 2 forms a preliminary conduction contact, especially when the material of the enameled wire is relatively soft, this effect is more obvious. The existence of the piercing mechanism improves the conduction effect between the commutator segment 2 and the enameled wire, makes the commutator segment 2 suitable for welding more types of enameled wires, and improves the product versatility of the commutator ...

Embodiment 2

[0053] see Figure 5-Figure 6 , in this embodiment 2, the side of the hook facing the main body has a hook surface 4, and the protective structure includes a Concave groove9. Specifically, in the existing commutator segment 2, the main body and the hook usually transition in a circular arc, but the arc angle is generally small. Taking the hook surface 4 as a plane as an example, such as the hook surface of the commutator segment 2 in the prior art There is no gap between the plane where 4 is located and the hook, so the accommodation space formed when the winding 7 is welded is relatively small, which may easily cause the winding 7 to be over-deformed or even broken. In this embodiment, the protection structure includes a groove 9 formed on the transition area 5 and recessed toward the inside of the hook relative to the hook surface 4, the cross section of the groove 9 may be, for example, square , triangular or arc-shaped, etc., preferably, in order to better fit the enamel...

Embodiment 3

[0056] see Figure 9-Figure 10 , as another embodiment for increasing the accommodating space of the winding 7, in this embodiment 3, the side of the main body facing the hook has a main body surface 6, and the main body surface 6 may be a plane, for example, so The protection structure includes a groove 10 formed on the transition area 5 and recessed toward the inside of the body relative to the body surface 6 . Similarly, the groove 10 is preferably arc-shaped, and there can be a smooth transition between the groove 10 and the hook, so as to adapt to the cross-sectional shape of the enameled wire, so as to better fit and accommodate the enameled wire, and improve the enameled wire and commutator segment. 2 conduction effect.

[0057] see Figure 11 and Figure 12 , when welding the enameled wire, the hook moves towards the main body, and the space formed between the hook and the main body becomes smaller. However, due to the existence of the groove 10, the accommodation s...

Abstract

The invention relates to the technical field of commutators and discloses a commutator segment, a commutator and a motor. The commutator segment comprises a main body and a hanging hook which are connected with each other. A transition region (5) is reserved between the main body and the hanging hook. A protective structure for preventing windings from being damaged during the welding process is formed inside the transition region (5). The commutator segment of the invention can be applied to the welding process of a wider variety of windings, and is better in product universality. The welding process of commutator segments and windings is improved, and the welding qualification rate of windings is increased. The manufacturing cost of motors is reduced. The motor working reliability is improved and the motor service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of commutators, in particular to a commutator segment with an improved structure, and further, the invention also relates to a commutator and a motor. Background technique [0002] A motor such as a brushed DC motor generally includes a stator and a rotor, the rotor having a shaft, a commutator secured to the shaft, a rotor core secured to the shaft, commutator segments wound onto the teeth of the rotor core and connected to the commutator. Conductively connected windings. The stator is electrically connected to the commutator segments through brushes, so as to supply power to the windings. Specifically, the commutator segment generally has a main body and a hook, the main body is electrically connected to the stator through a brush, and the hook is generally electrically connected to the winding hung on the hook by welding. [0003] The existing structure design of the commutator segment is not reasonable...
