Description
Technical field
The utility model is related to a kind of voice coil motors, particularly relate to a kind of conduction connecting structure of voice coil motor.
Background technology
Voice coil motor (VCM) has the characteristics that high frequency sound, high-precision.Its cardinal principle is led in a permanent-magnetic field
The DC current size for changing motor interior loop is crossed, to control the stretch position of spring leaf, is moved up and down to drive.Mobile phone is taken the photograph
Picture head widely uses VCM to realize automatic focusing function, and the position of camera lens can be adjusted by VCM, and clearly image is presented.Sound
Coil motor includes the components such as shell, camera lens, upper shrapnel, holder, lower shrapnel, lower cover, terminal, due to lower shrapnel and terminal, lower bullet
Piece will be realized with coil and is electrically connected, and need to weld together the two, and overall structure is determined and must be first welded, then will under
Gasket is loaded onto.Due to containing rosin in scolding tin, in the welding process, there are problems that easy quick-fried tin, once quick-fried tin, tin sweat(ing) splash down
In internal mechanism, component start is influenced, yields reduces.
In view of this, the designer for above-mentioned voice coil motor structure design on do not attain improve caused by many missings and
Inconvenience, and deeply conceive, and actively research improvement has a fling at and develops and design the utility model.
Utility model content
The purpose of this utility model is to provide a kind of electrical connections to stablize, the conduction connecting structure of reliable voice coil motor.
To achieve the above object, the technical solution of the utility model is：
A kind of conduction connecting structure of voice coil motor, including coil, holder, lower shrapnel, terminal and lower cover；The coil
It is wrapped on holder, cradle bottom surface is adhesively fixed in lower shrapnel along top surface, and holder, lower shrapnel and lower cover are superimposed together, end
Son is plugged in lower cover respectively；Be respectively equipped between the terminal and lower shrapnel and between coil and lower shrapnel homeotropic orientation or
The conductive film of person's anisotropy realizes being electrically connected for terminal and lower shrapnel and coil and lower shrapnel by conductive film.
After adopting the above scheme, since the lower shrapnel top surface of the utility model and bottom surface pass through conductive film and coil respectively
And terminal connection, as long as certain temperature or pressure are given when assembly above conductive film, make lower shrapnel, conductive film with
Coil and lower shrapnel, conductive film and terminal three closely connect, and the purpose of conducting is realized by conductive film；Compared to tradition
Welding electrically conducting manner, the utility model can avoid the problems such as tin cream spot welding generates rosin, dry joint, high solder joint, improves voice coil horse
The performance reached.The utility model is linked together with coil, lower shrapnel and terminal respectively by conductive film, without being welded
Operation avoids the insecure problem of electrical connection caused by the quick-fried tin in welding process, and there is electrical connection to stablize, is reliable excellent
Point.

Specific implementation mode
In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into
Row elaborates.
As shown in Figures 1 to 6, the utility model discloses a kind of conduction connecting structure of voice coil motor comprising coil
1, holder 2, lower shrapnel 3, terminal 4 and lower cover 5；The coil 1 is wrapped on holder 2,2 bottom surface of holder and edge in lower shrapnel 3
Top surface is adhesively fixed, and holder 2, lower shrapnel 3 and lower cover 5 are superimposed together, and terminal 4 is plugged on respectively in lower cover 5；The terminal
It is respectively equipped with the conductive film 6 of homeotropic orientation or anisotropy between 4 and lower shrapnel 3 and between coil 1 and lower shrapnel 3, passes through
Conductive film 6 realizes being electrically connected for terminal 5 and lower shrapnel 3 and coil 1 and lower shrapnel 3.
Homeotropic orientation conductive film is the compound for forming disperse conductive particles in adhesive insulating resin, is used it for
The bonding of component cures under conditions of heating pressurization, to realize energization and binding function；Anisotropy conductive film is profit
Conducting is made with conducting particles connection shrapnel and the electrode of terminal between the two, while being avoided that between adjacent two electrode and leading again
Logical short circuit, and reach the only purpose in Z-direction conducting.
The utility model replaces traditional tin cream spot welding using the conductive film of homeotropic orientation or anisotropy, by homeotropic orientation or
Person's anisotropy conductive film is placed between coil 1 and lower shrapnel 3 and lower shrapnel 3 and terminal 4, is given in the top of conductive film 6
Certain temperature or pressure makes coil 1, conductive film 6 closely be connect with lower 3 three of shrapnel, similarly descends shrapnel 3, conductive film 6
It is also closely connect with terminal three, the purpose of circuit turn-on is realized by conductive film 6.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
