Spring plate and camera module having same

Abstract

A spring plate includes a plate body having a through hole defined at the center, and a terminal perpendicularly extending from the plate body. The plate body includes an outer closed-loop frame, an inner closed-loop frame, and spring parts interconnected between the outer closed-loop frame and the inner closed-loop frame. The terminal has an end portion distal from the plate body with at least one through hole or a recess.

         5 . The spring plate of  claim 4 , wherein the recesses are exposed at a common edge of the terminal. 
     
     
         6 . The spring plate of  claim 5 , wherein the terminal is L-shaped, and comprises a first connection portion connected to the plate body, and a second connection portion perpendicular to the first connection portion, the second connection portion is distal from the plate body, and the recess are defined in the second connection portion. 
     
     
         7 . A camera module comprising:
 a lens;   an image sensor, and   a voice coil motor for moving the lens, the voice coil motor comprising:   a fixed unit, the fixed unit comprising a first accommodation chamber;   a movable unit received in the first accommodation chamber, the movable unit comprising a second accommodation chamber, the second accommodation chamber being configured for receiving the lens;   a supporting base mounted the bottom portion of the fixed unit, the supporting base comprising a supporting surface facing the fixed unit, the supporting surface being configured for supporting the fixed unit and the image sensor;   a spring plate comprising:
 a plate body having a through hole defined at the center thereof, the plate body comprising an outer closed-loop frame, an inner closed-loop frame, and a plurality of spring parts interconnected between the outer closed-loop frame and the inner closed-loop frame, the outer closed-loop frame and the inner closed-loop frame being respectively mounted on the fixed unit and the movable unit, and 
 a terminal perpendicular to the plate body, the terminal including an end portion distal from the plate body, the end portion of the terminal defining at least one of a through hole and a recess, and 
   an electrically conductive adhesive, the end portion of the terminal being electrically connected to the supporting base with the electrically conductive adhesive.   
     
     
         8 . The camera module of  claim 7 , wherein the at least one through hole comprises a plurality of through holes. 
     
     
         9 . The camera module of  claim 8 , wherein the terminal is L-shaped, and comprises a first connection portion connected to the plate body, and a second connection portion perpendicular to the first connection portion, the second connection portion is distal from the plate body, and the through holes are defined in the second connection portion. 
     
     
         10 . The camera module of  claim 9 , further comprising an electrically conductive pad formed on the supporting surface, the electrically conductive pad is configured for electrically connecting the terminal to the supporting base via the electrically conductive adhesive. 
     
     
         11 . The camera module of  claim 7 , wherein the at least one recess comprises a plurality of recesses. 
     
     
         12 . The camera module of  claim 11 , wherein the recesses are defined in a common straight edge of the end portion. 
     
     
         13 . The camera module of  claim 12 , wherein the terminal is L-shaped, and comprises a first connection portion connected to the plate body, and a second connection portion perpendicular to the first connection portion, the second connection portion is distal from the plate body, and the recesses are defined in the second connection portion. 
     
     
         14 . The camera module of  claim 13 , further comprising an electrically conductive pad formed on the supporting surface, the electrically conductive pad is configured for electrically connecting the terminal to the supporting base via the conductive adhesive.
