Abstract
The utility model provides a kind of anti-oxidant VCM shell fragments; the anti-oxidant VCM shell fragments include a through hole; also include the housing away from through hole, the inside casing around through hole and close to through hole and the elastic connection plate for connecting housing and inside casing, the housing, inside casing, the surface spraying of elastic connection plate have protection film layer.This case is simple in construction, easy to operate, improves production efficiency and product yield；Production routine is simplified, drops bottom employee's cost and risk；VCM shell fragments can be made to be avoided during assembling and use because failure welding caused by shell fragment oxide side itself, effectively increase the yield of product.
Description
Technical field
Autofocus motor field is the utility model is related to, more particularly to a kind of anti-oxidant VCM shell fragments.
Background technology
VCM（VoiceCoil Motor）, the voice coil motor also known as inside electronics, be motor one kind.Because principle and
Loudspeaker is similar, so being voice coil motor, has high frequency sound, high-precision feature.Its cardinal principle is in a permanent-magnetic field
It is interior, by changing the DC current size of motor interior loop, to control the stretch position of spring leaf, moved up and down so as to drive.
Mobile phone camera widely realizes automatic focusing function using VCM shell fragments, and the position of camera lens can be adjusted by VCM shell fragments, is in
Now clearly image.Prior art VCM shell fragments surface treatment easily cause oxidation it is bad, motor assembling during can influence to weld
Effect is connect, causes to weld bad influence motor characteristics.
Utility model content
The purpose of this utility model is to provide a kind of surface oxidation-resistant, improves the anti-oxidant VCM shell fragments of yield.
A kind of anti-oxidant VCM shell fragments, the anti-oxidant VCM shell fragments include a through hole, in addition to the housing away from through hole, enclose
Inside casing around through hole and close to through hole and the elastic connection plate for connecting housing and inside casing, the housing, inside casing, elastic connection
The surface spraying of plate has protection film layer.
Further, the housing is square frame, and the inside casing is circular inside casing.
Further, the symmetrical isolating construction of the housing, the symmetrical split-type structural of the inside casing.
Further, the internal diameter length of side of the housing is more than the external diameter length of side of the inside casing.
Further, the elastic connection plate is in semicircle shape.
Further, the material of the protection film layer uses organic solderability preservative.
Anti-oxidant VCM shell fragments of the present utility model, it is simple in construction, it is easy to operate, improve production efficiency and product yield；
Production routine is simplified, drops bottom employee's cost and risk；VCM shell fragments can be made to be avoided during assembling and use because bullet
Failure welding caused by piece oxide side itself, effectively increase the yield of product.
According to the accompanying drawings will be more to the detailed description of the utility model specific embodiment, those skilled in the art
Add clear of the present utility model above-mentioned and other purposes, advantages and features.
Brief description of the drawings
It is described in detail by way of example, and not by way of limitation with reference to the accompanying drawings hereinafter more of the present utility model specific real
Apply example.Identical reference denotes same or similar part or part in accompanying drawing.It should be appreciated by those skilled in the art that
What these accompanying drawings were not necessarily drawn to scale.In accompanying drawing：
Fig. 1 is the schematic diagram according to the anti-oxidant VCM shell fragments of the utility model one embodiment；
Fig. 2 is the diagrammatic cross-section according to the anti-oxidant VCM shell fragments of the utility model one embodiment.
Embodiment
Referring to Fig. 1,2, a kind of anti-oxidant VCM shell fragments, the anti-oxidant VCM shell fragments include a through hole 1, in addition to away from logical
The housing 2 in hole 1, the inside casing 3 around through hole 1 and close to through hole 1 and the elastic connection plate 4 for connecting housing 2 and inside casing 3, institute
Stating housing 2, inside casing 3, the surface spraying of elastic connection plate 4 has protection film layer 10.
In the present embodiment, according to VCM shell fragment material properties, in general VCM shell fragments use adonic BF158, the material
Matter collocation surface treatment liquid medicine, controls its processing temperature, spraying with making surface treatment liquid medicine and VCM bullets by way of the time
Piece surface sufficiently contacts, to reach the protection film layer 10 that product surface covers one layer very thin, to reach the water in air-isolation
Part and the effect of carbon dioxide, ensure that VCM shell fragment product surfaces are not oxidized, lift product quality.The system can be with etching
Line produces simultaneously, improves production efficiency, while utilize the production of system for computer program full automation.
Preferably, housing 2 is square frame 2, the inside casing 3 is circular inside casing 3.The symmetrical separation knot of housing 2
Structure, the symmetrical split-type structural of the inside casing 3.The internal diameter length of side of housing 2 is more than the external diameter length of side of the inside casing 3.
Elastic connection plate 4 is in semicircle shape, and the opening direction of semicircle shape is more stable away from circular hole 1, such structure.
The material of protection film layer 10 uses organic solderability preservative, and the flexibility of obtained diaphragm is good, flatness, stickiness
It is good, will not be to producing any adverse effect by patch surface.
So far, although those skilled in the art will appreciate that herein it is detailed have shown and described it is of the present utility model more
Individual exemplary embodiment, still, still can be public according to the utility model in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derived many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The scope of type is understood that and regarded as to cover other all these variations or modifications.
