Abstract
The utility model discloses the improved structure of a kind of voice coil motor base, including base body, electric-conductor；Described electric-conductor is arranged on base body；Described electric-conductor is parts integrated with base body, is coated with one layer of conducting film on electric-conductor top layer.Owing to electric-conductor is parts integrated with base body by this utility model, one layer of conducting film it is coated with again on electric-conductor top layer, reach the purpose of conduction, eliminate electric-conductor as the production process of independent metal part and assembly process, production technology is relatively simple, and the positional precision of electric-conductor is higher.
Description
Technical field
This utility model relates to a kind of voice coil motor, particularly relates to the improved structure of a kind of voice coil motor base.
Background technology
Voice coil motor has high frequency sound, high-precision feature.Its cardinal principle is in a permanent-magnetic field, by changing
The DC current size of motor interior loop, controls the stretch position of spring leaf, thus drives up and down motion.Mobile phone camera is wide
General use VCM realizes automatic focusing function, can be regulated the position of camera lens by VCM, presents image clearly.Voice coil motor
The parts such as including shell, camera lens, upper shell fragment, support, lower shell fragment, lower cover, as shown in Figure 1 and Figure 2, the shell of traditional voice coil motor
Being provided with metallic conduction part 1 ', 2 ', this metallic conduction part 1 ', 2 ' is arranged on shell 3 ' as independent parts, due to metal
Electric-conductor 1 ', 2 ' is independent metal parts, needs first to carry out independent punch forming, and also needs part metallic conduction part 1 ', 2 ' to make
Carrying out injection mo(u)lding for mold insert and assemble with shell, production technology is complex, and production cost is higher.
Summary of the invention
The purpose of this utility model is to provide the improved structure of a kind of production technology simple voice coil motor base.
For achieving the above object, technical solution of the present utility model is:
This utility model is the improved structure of a kind of voice coil motor base, including base body, electric-conductor；Described conduction
Part is arranged on base body；Described electric-conductor is parts integrated with base body, is coated with one on electric-conductor top layer
Layer conducting film.
Described electric-conductor includes the first electric-conductor and the second electric-conductor；The first described electric-conductor is arranged on base body
The both sides of a sidewall, the second electric-conductor is arranged on two corners of base body.
Use after such scheme, owing to electric-conductor is parts integrated with base body by this utility model, then
Electric-conductor top layer is coated with one layer of conducting film, reaches the purpose of conduction, eliminates the electric-conductor production process as independent metal part
And assembly process, production technology is relatively simple, and the positional precision of electric-conductor is higher.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As shown in figures 3 to 6, this utility model is the improved structure of a kind of voice coil motor base, including base body 1, leads
Electricity part 2.
Described electric-conductor 2 includes the first electric-conductor 21 and the second electric-conductor 22.The first described electric-conductor 21 is arranged on
The both sides of one sidewall of base body 1, the second electric-conductor 22 is arranged on 1 two corners of base body.
Described electric-conductor 2 is identical with the material of base body 1, is all working of plastics.
The first described electric-conductor 21 and the second electric-conductor 22 are parts integrated with base body 1, lead first
The electricity top layer of part 21 and the top layer of the second electric-conductor 22 are all coated with one layer of conducting film, the top layer of the first electric-conductor 21 and the second conduction
After part 22 plated film, there is conduction effect.
Emphasis of the present utility model is that electric-conductor is and the coated film plastic part of base body one.
The above, only this utility model preferred embodiment, therefore can not limit what this utility model was implemented with this
Scope, the equivalence change i.e. made according to this utility model claim and description and modification, all should still belong to this reality
In the range of containing with new patent.
