Abstract
The utility model relates to an outer rotor fan stator winding and circuit board connection structure in which the connection structure between three-phase leads of the stator winding and a speed regulation circuit board is simple and reliable. A stator aluminum support has a concave-convex structure and the stator winding is fixed on the convex bench of the stator aluminum support, an insulation sheet is embedded into a groove in the stator aluminum support, and the UVW three-phase outgoing lines of a varnished wire which is located in the stator winding are sleeved with an insulating sleeved respectively and pass through a conduit hole in the insulation sheet so as to be welded with a wire connection pin on the circuit board which is located in the stator aluminum support groove. The structure has the following advantages: firstly, the simple and reliable connection between the three-phase leads of the stator winding and the built-in speed regulation circuit board can be realized; and secondly, the advantage of low manufacturing cost can be realized.
Description
Technical field
The utility model relates to a kind of stator winding three phase terminals and the alignment circuit board connecting structure is simple, stator winding and circuit-board connecting structure outer rotor blower fan reliably, belongs to the outer rotor blower fan partial structurtes and makes the field.
Background technology
CN 201202684U, title " a kind of external rotor axial-flow fan ", mainly comprise rotor, fan blade, rotating shaft, stator core, rotor core and stator line bag, two ends of rotating shaft are provided with bearing, rotor core is sleeved on stator core, it is characterized in that: described rotating shaft is fixedly connected with stator core, one end face of rotating shaft is provided with inner end cap, and inner end cap is fixedly connected with rotor; Be connected with the stator retaining frame on stator core, stator line bag is arranged on the stator retaining frame; Rotor is fixedly connected with being connected ear, connects connection reference column on ear and is inserted on connecting hole on fan blade, and will connect ear and fan blade is fixed together by connecting bolt.Its weak point: both the alignment circuit plate can't be arranged in casing, and also can't realize easy, the reliable connection between stator coil and alignment circuit plate in stator winding.
The utility model content
Purpose of design: avoid the weak point in background technology, design a kind of stator winding three phase terminals and the alignment circuit board connecting structure is simple, stator winding and the circuit-board connecting structure of reliable a kind of outer rotor blower fan.
Design: in order to realize above-mentioned purpose of design.The utility model is on structural design, and stator winding is comprised of stator core, enamelled wire, insulation cushion rubber, and its stator winding is fixed on the stator aluminum frame.The lead-out wire of enamelled wire is made of U V W three-phase, be wound into after the fixing wiring pin of scolding tin on circuit board again scolding tin pass insulating trip after adding insulating sleeve on three phase terminals of enamelled wire after and fix, thereby reach the purpose that syndeton is simple, reliable, cost is low.
Technical scheme: a kind of stator winding of outer rotor blower fan and circuit-board connecting structure, stator aluminum frame concave-convex surface structure and stator winding are fixed on the boss frame of stator aluminum frame, insulating trip is embedded in the groove of stator aluminum frame, and the U V W three-phase lead-out wire cover that is arranged in the stator winding enamelled wire has insulating sleeve and passes the insulating trip guide hole and weld with the wiring pin on the circuit board that is positioned at stator aluminum frame groove.
The utility model is compared with background technology, and the one, realized easy, the reliable connection between stator winding three phase terminals and built-in alignment circuit plate; The 2nd, low cost of manufacture.
