Abstract
A kind of voice coil motor spring leaf of anti-deformation stable type, relate to voice coil motor technical field, solve existing voice coil motor spring leaf when welding pin terminal, or easily cause spring leaf to occur deformation at voice coil motor assembling flow path, affect spring leaf characterisitic parameter, poor quality, fraction defective high-technology is not enough, includes the solder terminal of spring leaf body and linking springs sheet body; It is characterized in that: described solder terminal is provided with the bar shaped groove of one or more of etching hollow out.The position that pin terminals is welded and fixed is one or more fine rule, make soft between solder terminal with spring leaf body connection, the one-sided electric resistance welding integrity problem of effective solution, this shape can ensure that use smaller power electric resistance welding equipment and less welding pressure can complete the electrical connection between solder terminal and pin terminals; The deformation produced when ensureing to weld or when voice coil motor assembles does not affect the characterisitic parameter of spring leaf body, good stability.
Description
Technical field
The utility model relates to voice coil motor technical field, is specifically related to the solder terminal architecture advances aspect of voice coil motor spring leaf.
Background technology
Voice coil motor is a kind of is the device of mechanical energy by electric energy conversion, and realizes the motion of linear pattern and limited pivot angle.Interaction in the magnetic field utilizing magnetic field and hot-wire coil conductor from permanent-magnet steel to produce between magnetic pole produces the device of regular motion; Be usually used at present carrying out lens driving in mobile phone camera, realize auto-focusing and regulate.The solder terminal of the voice coil motor spring leaf in embody rule process needs welding pin terminal, what existing domestic and international voice coil motor producer was more is adopt electric resistance welding pin terminals, solder terminal and pin terminals are when welding but be all adopt plate to weld mutually with plate, do not do special processing to welding position.
According to one-sided welding, two electrodes namely welded are positioned on same workpiece, and be applied in the middle of voice coil motor assembling, two electrodes only need good contact springs or terminal, and technique is simple, but reliability is poor, and not prison welding is solid.As ensured its reliability, must adopt bilateral welding manner, two electrodes namely welded must separate, and be applied in the middle of voice coil motor assembling, two electrodes need to contact with spring leaf solder terminal and pin terminals respectively.Electrode enters voice coil motor assembling flow path, complex process after must first being welded with pin terminals by spring leaf solder terminal, easily causes spring leaf to occur deformation, affect spring leaf characterisitic parameter after separating, and fraction defective is high and efficiency effect is low, poor reliability.
Summary of the invention
In sum, the purpose of this utility model is to solve existing voice coil motor spring leaf when welding pin terminal, or easily cause spring leaf to occur deformation at voice coil motor assembling flow path, affect spring leaf characterisitic parameter, poor quality, fraction defective high-technology is not enough, and proposes a kind of voice coil motor spring leaf of anti-deformation stable type.
For solving the technical problem that the utility model proposes, the technical scheme of employing is: a kind of voice coil motor spring leaf of anti-deformation stable type, includes the solder terminal of spring leaf body and linking springs sheet body; It is characterized in that: described solder terminal is provided with the bar shaped groove of one or more of etching hollow out.
Described bar shaped groove is perpendicular to described solder terminal.
Described solder terminal is also provided with a breach groove of etching hollow out; Described breach groove communicates with its one end of described each bar shaped groove is vertical.
The beneficial effects of the utility model are: the utility model is in spring leaf etching production process, on solder terminal, be provided with the bar shaped groove of one or more of etching hollow out simultaneously, the position be welded and fixed with pin terminals is one or more fine rule, make soft between solder terminal with spring leaf body connection, the one-sided electric resistance welding integrity problem of effective solution, this shape can ensure that use smaller power electric resistance welding equipment and less welding pressure can complete the electrical connection between solder terminal and pin terminals; The deformation produced when ensureing to weld or when voice coil motor assembles does not affect the characterisitic parameter of spring leaf body, good stability.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the structure for amplifying schematic diagram of part A in Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and the preferred specific embodiment of the utility model, structure of the present utility model is further described.
With reference to shown in Fig. 1, the utility model includes the solder terminal 2 of spring leaf body 1 and linking springs sheet body 1, and solder terminal 2 is positioned at the outside of the installing hole 11 of spring leaf body 1; With reference to shown in Fig. 2, described solder terminal 2 is provided with the bar shaped groove 21 of one or more of etching hollow out, described each bar shaped groove 21 is side by side perpendicular to described solder terminal 2, region between adjacent two bar shaped grooves 21 formed one thin-line-shaped, this region that is to say and pin terminals welding region, applies also to be not easy to cause spring leaf body 1 deformation when pressure carries out resistance welded to this region.
In order to further avoid spring leaf body 1 to occur deformation, described solder terminal 2 is also provided with a breach groove 22 of etching hollow out; Described breach groove 22 communicates with its one end of described each bar shaped groove 21 is vertical, and the one end, thin-line-shaped region also namely between adjacent two bar shaped grooves 21 is in free state.
Claims (3)
