For problems of the prior art, the purpose of this utility model is to provide a kind of voice coil motor being provided with electric connection point escape groove, by putting side at the electric connection point of coil lead terminal and leaf spring, escape groove is set, play the effect of electric connection point being put isolation, contact type welding and Problems existing in contactless welding can be solved.
For achieving the above object, the utility model is by the following technical solutions:
Be provided with the voice coil motor of electric connection point escape groove, comprise lower reed, lens mount, coil, magnet and upper reed plate, the lead terminal of described coil is electrically connected with described lower reed or upper reed plate; Described electric connection point side arranges escape groove, and described escape groove penetrates described lower reed or upper reed plate.
Further, described escape groove linearly shape or shaped form.
Further, described escape groove width >=0.02mm.
Further, described escape groove is wide or not wide.
Further, the structure of described electrical connection for being welded to connect, described in be welded to connect and adopt pressure welding, soldering or join by fusion.Soldering can be the mode such as tin cream soldering or the soldering of tin silk, and join by fusion can be the modes such as gas weldering, arc welding, Laser Welding, electron beam welding, supersonic welding.
Further, the structure of described electrical connection is that conducting resinl connects.
Further, described escape groove is between electric connection point and the fixing hole of lower reed or upper reed plate, and described fixing hole coordinates the vertical columns on described lens mount to fix lower reed or upper reed plate.
Further, described lower reed stretches out connecting plate by spring string, and connecting plate outwards connects reed terminal, and reed terminal arranges two, is divided into both positive and negative polarity.
Further, described electric connection point both sides are provided with described escape groove, and two escape groove are not communicated with, and the lead terminal of described coil is connected electrically on the metallic object between two escape groove.
Further, described escape groove is the groove of closed at both ends on described lower reed or upper reed plate, or the breach on described lower reed or upper reed plate.
The voice coil motor adopting said structure to arrange, has the following advantages:
Escape groove being set by putting side at the electric connection point of coil lead terminal and leaf spring, playing the effect isolated by electric connection point, although be incomplete isolation, can solve contact type welding with Problems existing in contactless welding.
Due to the buffer action of escape groove, welding compound can being avoided to spread uncontrollably to electric connection point periphery, also can weaken the intensity of electric connection point place reed metallic object, to applying pressure herein, being not easy to cause other position distortions of reed.
After adopting said structure, coil lead terminal is electrically connected with leaf spring also can be more reliable, and circuit structure obtains optimization.
