Abstract
The utility model relates to a signal output structure of an external rotor fan, which comprises a Hall inductor, a leading wire for outputting signals of the Hall inductor, an installing support for installing the Hall inductor and a magnetic body arranged on a rotor end ring; the signal output structure is characterized by also comprising a connecting plate; the installing support is arranged on the connecting plate; and the back of the connecting plate is provided with three strips of cladding copper corresponding to the pins of the Hall inductor; and each pin is electrically connected with the three strips of cladding copper through welding spots respectively. An electrical machine end cover does not need processed and installed holes and notches, and thereby, the processing procedures are reduced, and the processing cost is reduced. Due to the fact that the Hall inductor is fixed on the connecting plate and is connected by directly adopting the cladding copper, and the leading wire is connected also by the cladding copper, the phenomena of pin breaking and welding drop of the Hall inductor do not exist; the installation is convenient and simple; moreover, new procedures do not need adding; and the welding of the Hall inductor can be carries out while an electrical machine welds the leading wire.
Description
Affiliated technical field
The utility model relates to a kind of signal export structures such as rotating speed of outer rotor blower fan.
Background technique
At present, as shown in Figure 1, the tach signal of outer rotor blower fan output passing through hall sensor.During installation, hall sensor is packed on the support (2), and then be fixed on the end cap (3) of motor, the magnetic with its induction is installed in (not shown) on the end ring of rotor.During machine operation, rotor and the magnetic that is fixed on the rotor end ring rotate together, promptly produce induced signal when hall sensor and magnetic meet, and hall sensor is exported the signal of being responded to by lead-in wire (4).Because it is little that the volume of hall sensor support is installed, mounting hole is also little on the electric motor end cap, difficult processing, and efficient is low, and needs a processing breach (31) fixed support on end cap; Easily broken or the sealing-off of the pin of hall sensor, it is unreliable to work.
The model utility content
The utility model provides a kind of minimizing manufacturing procedure for the deficiency that overcomes existing structure, cuts down finished cost, and the signal export structure of a kind of outer rotor blower fan of reliable operation is installed easily.
In order to achieve the above object, the utility model is achieved in that it is a kind of signal export structure of outer rotor blower fan, comprises the hall sensing device, with the lead-in wire of the signal of hall sensing device output, the mounting bracket of hall sensing device is installed and is installed in magnetic on the rotor end ring; It is characterized in that: comprise that also wire board, mounting bracket are installed on the wire board, be provided with three the deposited copper corresponding with the pin of hall sensing device at the back side of wire board, each pin is electrically connected by solder joint with three deposited copper respectively.
Be provided with a socket on described mounting bracket, the hall sensing device is inserted in the socket.
The beneficial effect of the utility model structure is that electric motor end cap need not reprocessed the hole and the breach of installation, has reduced manufacturing procedure, has reduced processing cost.Because hall sensor is fixed on the wire board, directly adopt and apply the copper connection, lead-in wire also connects by applying copper, the phenomenon that does not exist disconnected pin of hall sensor and welding to come off, easy for installation simple, and not needing to increase new operation, the welding of hall sensor can be carried out when the motor welding lead simultaneously.
