Specific embodiment
Describe spindle motor below with reference to accompanying drawings in detail according to disclosure exemplary embodiment.
Fig. 2 is the skeleton view of diagram according to the spindle motor of disclosure exemplary embodiment.
With reference to Fig. 2, comprise base 110, substrate 120 and electric motor units 130 according to the spindle motor of disclosure exemplary embodiment.
Hereinafter, in description for the direction of the building block that comprises base 110 and surface, surface and direction facing to the vertical upside of base 110 are known as " upper surface and upside ", are known as " lower surface and downside " facing to the surface and the direction of the vertical downside of base 110.
Base 110 is made by metal material, and the downside of base 110 and described product connect.The upper surface of the downside of substrate 120 and base 110 connects, and simultaneously, electric motor units 130 vertically is erected on the base 110 and with base 110 and connects.
Coil 131a at stator 131 places of electric motor units 130 is connected with substrate, to receive external energy.Therefore, when the function of current when the coil 131a, utilize the electromagnetic field that between stator 131 and rotor 133, forms to come rotary rotor 133, be rotatably installed in the disc on the rotor yoke 133a of rotor 133 thus.
Substrate 120 according to the spindle motor of exemplary embodiment of the present disclosure is constructed to only have the circuit that is used for drive motor units 130, thereby need be formed for connecting the medium of substrate 120 and described object.At this moment, two or more objects at least can be set, described object comprises the main substrate or the stepper motor of power supply, described product.
For this reason, substrate 120 and described object can be connected to each other by FFC 140.In other words, the side of FFC 140 and opposite side are welded to respectively on the splicing ear 121 and described object that is formed on the substrate 120.
Spindle motor according to disclosure exemplary embodiment is constructed to only have the substrate 120 that is used for drive motor units 130, and the size of base 110 and substrate 120 is big or small basic identical.Therefore, reduce the size of substrate 120 and the size of base 110, thereby saved manufacturing cost.
FFC 140 is formed with insulating coating 141 and a plurality of connection terminal 143, wherein, the center surface of connection terminal 143 is insulated coating 141 and encases, and an end of described connection terminal and another ends exposed are in the outside of insulating coating, to be welded to respectively on substrate and the object.
Connection terminal is very thin, thereby the part easy deformation that is exposed to insulating coating 141 outsides in the connection terminal.In addition, because terminals are careful, correct position is adjusted in the position that therefore is difficult to connection terminal that will distortion, thereby also is difficult to by connection terminal 143 is adjusted to correct position substrate 120 and object are welded to assigned address.
The encapsulation transportation that being used for after an end with connection terminal 143 is welded to substrate 120 is connected with object, the easier generation of the distortion of connection terminal 143.Therefore, another end of being connected with object of connection terminal 143 ninety-nine times out of a hundred all can the occurrence positions distortion.
FFC 140 according to the spindle motor of exemplary embodiment of the present disclosure is formed with the reinforcing membrane 145 that is used to prevent connection terminal 143 distortion.
In other words, reinforcing membrane 145a, 145b can encase an end and another end of connection terminal with supporting, and can be welded to respectively on substrate 120 and the described object in end portion of the connection terminal 143 between insulating coating 141 and the reinforcing membrane 145a and in another end portion of the connection terminal 143 between insulating coating 141 and the reinforcing membrane 145b.
Therefore, the part that is exposed to insulating coating 141 outsides in the connection terminal 143 can be out of shape, thereby can easily described connection terminal be welded on substrate 120 and the described object.
Fig. 3 is the skeleton view that diagram is welded to FFC the state on the substrate of Fig. 2.
With reference to Fig. 3, reinforcing membrane 145a, 145b can be formed by insulating material PET.An end portion of the connection terminal 143 between insulating coating 141 and reinforcing membrane 145a is soldered on the substrate 120, wherein, reinforcing membrane 145a is folded, and to cover the end portion of connection terminal 143, reinforcing membrane 145a can provide insulating effect to guarantee described connection terminal safety.At this moment, the reinforcing membrane 145b that is folded can cover another end portion on the described object of being soldered in the connection terminal 143, thereby produces insulating effect.
Fig. 4 is the skeleton view that diagram is welded to FFC another state on the substrate of Fig. 2.
With reference to Fig. 4, the end portion of the connection terminal 143 between insulating coating 141 and reinforcing membrane 145a can be soldered on the substrate 120, and wherein reinforcing membrane 145a is cut off and removes.Another end portion of connection terminal 143 is soldered on the described object, and wherein another reinforcing membrane 145b can be cut off and remove.
An industrial applicability according to spindle motor of the present disclosure is, only be provided for drive motor substrate and with the essentially identical base of size of substrate, reduce manufacturing cost thus.
Another industrial applicability according to spindle motor of the present disclosure is, FFC is soldered on the connector of substrate being used to connecting substrate and object, thereby avoids using independent connector, further reduces manufacturing cost.
Another industrial applicability according to spindle motor of the present disclosure is, reinforcing membrane support among the FFC be exposed to the outside and be soldered to substrate and object on connection terminal, thereby avoid the connection terminal distortion, so connection terminal can be welded to accurately on substrate and the object.
