Description

Technical Field

[0001] The utility model relates to the technical field of stator half assemblies, in particular to a stator half assembly structure. Background Art

[0002] A water pump is a machine that transports or pressurizes liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the liquid's energy. It is primarily used to transport liquids including water, oil, acids and alkalis, emulsions, suspensions, and liquid metals. With increasing demands for energy conservation and environmental protection, pumps, as key power sources, must also meet high efficiency and low energy consumption standards.

[0003] The existing stator assembly, such as the prior art with application number CN201820728618.3, includes a casing, a stator core, a flexible elastic layer, a first flange layer, a second flange layer and a flat layer. Due to the setting of the flexible elastic layer in the stator assembly, the contact between the casing and the stator core is a local rigid structure and a local flexible structure. Such a setting is beneficial to reducing the vibration of the motor and at the same time helping to increase the heat dissipation capacity of the casing.

[0004] The brushless motor has three phases, and the lead wires are usually connected in a Y-type or triangle shape. Each phase needs to be connected by a wire, and the connections between phases will cross each other. After crossing, on the one hand, the risk of conduction between wires will increase. On the other hand, the overlapping of wires will affect the external interference and increase the volume size. Utility Model Content

[0007] Preferably, the wire passing device includes a plastic wire passing disc and a wire blocking step, which is installed on the plastic wire passing disc; the wire blocking step facilitates wire passing, eliminates stacking of wires, and replaces it with a single-layer wire passing, which reduces risks while reducing the size and space.

[0008] Preferably, the wire-blocking step is divided into three layers from the inside to the outside; the first layer is the U phase, the second layer is the V phase, and the third layer is the W phase, ensuring that the wire passing is completely fitted into the plastic wire tray, facilitating the passing of three-phase wires, reducing risks and shrinking the size and space.

[0009] Preferably, the installation mechanism includes a terminal and a barb, and the terminal is installed with barbs on both sides, and the terminal can be installed on a plastic wire tray; the barbs on both sides of the terminal make it easy to install the terminal on the plastic wire tray.
