Description
Technical field
The utility model is related to a kind of voice coil motor, more particularly to a kind of improved speech coil motor.
Background technology
Currently, voice coil motor has many advantages, such as that small, electricity consumption is few, cheap, it is suitable as with camera function
Electronic product, such as digital phase, mobile phone and DV driver.Voice coil motor generally includes coil, activity carrying
Seat and magnet, coil are wound in the outer wall of bearing seat, and coil generates electromagnetic field effect after being powered and makes magnet stress in magnet
Bearing seat movement is driven, camera lens is installed on bearing seat, the spacing of camera lens and electronic product Image Sensor can be changed in this way,
The effect of reaching zoom.But in the prior art, it usually needs conducting wire is wrapped in bearing seat outer wall manually, and conducting wire is thinner,
It is easily broken off during winding and moving back paint welding so that the qualification rate of product is low, affects the quality of product.
Utility model content
The purpose of this utility model is to provide a kind of improved speech coil motor, by the way that insulation base is arranged in bearing seat periphery
Plate opens up on insulating substrate and buries slot, by conducting wire it is embedded with bury in slot so that being broken will not occur during the installation process in conducting wire shows
As ensure that the quality of product, improving product qualification rate.
To achieve the above object, the utility model provides a kind of improved speech coil motor, including pedestal, in the pedestal
It is provided with the bearing seat that can be moved in pedestal, the bearing groove for loading camera lens, the carrying are provided on the bearing seat
It is mounted with magnet in seat, the insulating substrate being arranged in bearing seat periphery is installed on the pedestal, on the insulating substrate
It is provided with and buries slot, described bury is embedded with conducting wire in slot, described conducting wire one end, which is stretched out, buries slot and be arranged in insulating substrate outer rim, described
The conducting wire other end is connected with the through-hole opened up on insulating substrate, and the conducting wire generates electromagnetic field after being powered and can interact with magnet
Bearing seat is pushed to be moved in pedestal.
Compared with prior art, the beneficial effects of the utility model are, by the way that insulating substrate is arranged in bearing seat periphery,
It being opened up on insulating substrate and buries slot, conducting wire is buried and buried in slot so that the phenomenon that fracture will not occur during the installation process in conducting wire,
The quality that ensure that product, improves product qualification rate, and the utility model can be used in electro-photographic product.
The conductor part is embedded in slot as a further improvement of the utility model, and such conducting wire has part sudden and violent
Be exposed at and bury outside slot, the electromagnetic field that generates can more preferably more directly interact with magnet after conducting wire is powered so that bearing seat by
The motive force bigger arrived.
The interior of slot that bury buries channel opening and gradually subtracts to burying trench bottom without leave as a further improvement of the utility model,
It is small, it can be embedded in slot more convenient for conductor part in this way.
The insulating substrate is equipped with multiple and is symmetricly set on bearing seat as a further improvement of the utility model,
Periphery, can allow in this way bearing seat by bigger motive force and ensure bearing seat stress equalization.
Guide post is provided on the pedestal as a further improvement of the utility model, the guide post extends vertically through
Bearing seat can make bearing seat not deviate by direction when stress moves in this way.
The guide post is symmetrically arranged with multiple as a further improvement of the utility model, in this way can be further
Ensure that bearing seat can be moved along the optical axis direction of camera lens, is not in the deviation in direction.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model insulating substrate structural schematic diagram.
Fig. 3 is that the utility model buries slot structure schematic diagram.
Wherein, 1 pedestal, 2 bearing seats, 3 magnet, 4 guide posts, 5 insulating substrates, 6 bearing grooves, 7 conducting wires, 8 through-holes, 9 bury slot.
Specific implementation mode
The utility model is further illustrated below in conjunction with the accompanying drawings：
A kind of improved speech coil motor as shown in Figs. 1-3, a kind of improved speech coil motor, including pedestal 1, the pedestal
It is provided with the bearing seat 2 that can be moved in pedestal 1 in 1, the bearing groove 6 for loading camera lens, institute are provided on the bearing seat 2
It states and is mounted with magnet 3 in bearing seat 2, the insulating substrate 5 being arranged in 2 periphery of bearing seat is installed on the pedestal 1, it is described
It is provided on insulating substrate 5 and buries slot 9, described bury is embedded with conducting wire 7 in slot 9,7 one end of the conducting wire, which is stretched out, buries slot 9 and be arranged
5 outer rim of insulating substrate, 7 other end of the conducting wire are connected with the through-hole 8 opened up on insulating substrate 5, and the conducting wire 7 generates after being powered
Electromagnetic field can interact with magnet 3 pushes bearing seat 2 to be moved in pedestal 1；7 part of the conducting wire is embedded in slot 9；Institute
