And same group of two memorial alloy posts are electrically connected the positive terminal and negative terminal, form complete circuit and return
Road.
Further, the quantity of some memorial alloy posts is even number.
Further, outer convex edge is provided with the carrier, some memorial alloy posts are connected on the outer convex edge.
Further, between the stereo circuit on some memorial alloy posts and the carrier by a conducting resinl or
The mode of welding tin cream electrically connects.
Further, between some memorial alloy posts and the positive terminal or negative terminal by a conducting resinl or
The mode that person welds tin cream electrically connects.
Further, the positive terminal and negative terminal are metal PIN.
Further, in addition to the shell that is set on the base.
A kind of camera module, including above-mentioned autofocus motor.
The utility model has the advantages that：Some memorial alloy posts of the autofocus motor are one group two-by-two,
