Abstract
The utility model discloses a kind of improved structure of SMD voice coil motor, including Shang Gai, upper spring leaf, support, coil, magnet, lower spring piece, lower cover, terminal；Described lower cover is fixed on the bottom of lid, lower cover middle part has a mesopore for allowing camera lens to pass through, coil is socketed on support, magnet is arranged in upper lid and respectively positioned at the outside of coil, upper spring leaf and lower spring piece are all nested with upper lid and are located above and below coil respectively, the top of terminal pass after the top surface of lower cover with the welding of lower spring piece, the bottom of terminal passes the bottom surface of lower cover and concordant with the bottom surface of lower cover, the lower surface of terminal and the welding circuit board below lower cover.Because the bottom of the utility model terminal passes the bottom surface of lower cover and concordant with the bottom surface of lower cover, lower surface and the welding circuit board being located at below lower cover by terminal, this structure causes that welding procedure is relatively simple, takes up room smaller, meets the requirement of product miniaturization.
Description
Technical field
The utility model is related to a kind of voice coil motor, more particularly to a kind of improved structure of SMD voice coil motor.
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, so as to drive up and down motion.Mobile phone camera is wide
General use VCM realizes automatic focusing function, and the position of camera lens can be adjusted by VCM, and clearly image is presented.Such as Fig. 1 institutes
Show, voice coil motor includes shell 1 ', upper shell fragment 2 ', lower shell fragment 3 ', coil 4 ', magnet 5 ', lower cover 6 ', support 7 ', terminal 8 ' etc.
Part, the top of terminal 8 ' pass after the top surface of lower cover 6 ' with the welding of lower shell fragment 3 ', the bottom of terminal 8 ' passes the bottom of lower cover 6 '
With the welding circuit board being located at below lower cover 6 ' behind face, this mode commonly used is to be plugged on two terminals 8 ' of voice coil motor
On circuit board in specific through hole, this structure needs to take larger space, and the requirement minimized with product is not inconsistent.
The content of the invention
The purpose of this utility model is the improvement knot for providing the smaller SMD voice coil motor of a kind of process is simple, product
Structure.
To achieve the above object, technical solution of the present utility model is：
The utility model is a kind of improved structure of SMD voice coil motor, including Shang Gai, upper spring leaf, support, coil,
Magnet, lower spring piece, lower cover, terminal；Described lower cover is fixed on the bottom of lid, and lower cover middle part has one allows camera lens to pass through
Mesopore, coil is socketed on support, and magnet is arranged in upper lid and respectively positioned at the outside of coil, upper spring leaf and lower spring
Piece is all nested with upper lid and is located above and below coil respectively, and terminal is arranged on lower lid；The top of described terminal
Pass after the top surface of lower cover with the welding of lower spring piece, the bottom of terminal passes the bottom surface of lower cover and concordant with the bottom surface of lower cover.
Described terminal is used as mold insert and lower cover secondary injection molding.
After using such scheme, because the bottom of the utility model terminal passes the bottom surface of lower cover and is put down with the bottom surface of lower cover
Together, the lower surface by terminal and the pad solder of the circuit board being located at below lower cover, this structure cause welding procedure more
Simply, take up room smaller, meet the requirement of product miniaturization.
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.

Fig. 1 is the three-dimensional exploded view of the voice coil motor commonly used；
Fig. 2 is three-dimensional exploded view of the present utility model；
Fig. 3 is the axonometric drawing of the utility model lower cover part；
Fig. 4 is the axonometric drawing of the utility model terminal and welding circuit board；
Fig. 5 is the sectional view of the utility model terminal and welding circuit board.
Specific embodiment
As shown in Fig. 2 the utility model is a kind of improved structure of SMD voice coil motor, including upper lid 1, upper spring leaf
2nd, support 3, coil 4, magnet 5, lower spring piece 6, lower cover 7, terminal 8.
Described lower cover 7 is fixed on the bottom of lid 1, and the middle part of lower cover 7 has a mesopore for allowing camera lens to pass through, coil 4
It is socketed on support 3, magnet 5 is arranged in upper lid 1 and respectively positioned at the outside of coil 4, upper spring leaf 2 and lower spring piece 6 are all
It is nested with upper lid 1 and is located above and below coil 4 respectively.
With reference to shown in Fig. 3-Fig. 5, the top of described terminal 8 pass after the top surface of lower cover 7 with lower spring piece 6 against and weld
Connect, the bottom of terminal 8 passes the bottom surface of lower cover 7 and concordant with the bottom surface of lower cover 7, i.e. on a horizontal plane, under terminal 8
End face is welded with the circuit board 10 positioned at the lower section of lower cover 7.The Surface Mounting Technology of voice coil motor can be so realized, occupancy is effectively reduced
Space, meets the requirement of product miniaturization.
In order to terminal 8 easy to process, described is used as mold insert and the secondary injection molding of lower cover 7.
Emphasis of the present utility model is that：The lower end of terminal is concordant with lower cover bottom surface.
The above, only the utility model preferred embodiment, therefore the utility model implementation can not be limited with this
Scope, i.e., the equivalence changes made according to present utility model application the scope of the claims and description and modification, all should still belong to this reality
In the range of being covered with new patent.
