Abstract
The utility model discloses an adopt laser fusion bonding to realize voice coil loudspeaker voice coil motor structure who connects, include shell fragment and terminal down, the opposite face of lower shell fragment and terminal on set up the through -hole, the upper end of terminal is fixed on the shell fragment has the bottom surface of through -hole under through laser welding's mode. Because the utility model discloses down seting up the one or more through -hole on the opposite face of shell fragment and terminal, during the welding, not only forming the face of weld under between the top surface of shell fragment bottom surface and terminal, the top surface of shell fragment through -hole and terminal forms the face of weld between also under, and the face of weld is more, great for down shell fragment and terminal be connected more firmly.
Description
Technical field
This utility model relates to a kind of camera installation, particularly relates to a kind of voice coil motor structure using laser welding to realize connection.
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, thus drives up and down motion.Mobile phone camera uses VCM to realize automatic focusing function widely, can be regulated the position of camera lens by VCM, presents image clearly.Voice coil motor includes the parts such as shell, camera lens, upper shell fragment, support, lower shell fragment, lower cover, terminal, lower shell fragment bottom surface is fixed together by the way of welding with the end face of terminal, it it is the most all the welding being realized both by stannum silk, but, it is contained within scaling powder due to stannum in welding process, there will be the phenomenon of quick-fried stannum during welding, thus affect the action of voice coil motor.
In view of this, the utility model proposes a kind of laser welding that uses overcoming described defect and realize the voice coil motor structure connected, this case thus produces.
Utility model content
The purpose of this utility model is that the laser welding that uses providing a kind of firm welding realizes the voice coil motor structure connected.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of voice coil motor structure using laser welding to realize connection, including lower shell fragment and terminal；Described lower shell fragment offers one or more through hole on the opposite face of terminal, and the upper end of terminal is fixed on lower shell fragment by the way of laser welding to be had on the bottom surface of through hole.
Described lower shell fragment offers a through hole on the opposite face of terminal.
Two corners of one side of described lower shell fragment are connected together with a terminal soldering respectively.
The one or more boss of the end face of described terminal upwards projection, this boss is positioned at the underface of the through hole of lower shell fragment.
The internal diameter of described lower shell fragment through hole is less than the external diameter of boss.
One in generally circular in shape, square, the triangle of described lower shell fragment through hole；One in generally circular in shape, square, the triangle of described terminal end face convex platform.
Owing to offering one or more through hole on the shell fragment opposite face with terminal under this utility model, during welding, between lower shell fragment bottom surface and the end face of terminal, not only form solder side, also solder side is formed between lower shell fragment through hole and the end face of terminal, solder side is more, bigger so that lower shell fragment is the most firm with the connection of terminal.
Meanwhile, end face at terminal is convex is provided with boss, can well solve owing to there is burr or injustice in lower cover injection moulding process, and terminal is positioned over down when covering so that the end face of lower shell fragment bottom surface and terminal can not well be fitted, the problem causing not prison welding.
With specific embodiment, this utility model is further described below in conjunction with the accompanying drawings.

Detailed description of the invention
As Figure 1-Figure 4, this utility model uses laser welding to realize first embodiment of the voice coil motor structure connected, and it includes lower shell fragment 1 and terminal 2.
Described lower shell fragment 1 offers a through hole 11 on the opposite face of terminal 2, and the upper end of terminal 2 is fixed on lower shell fragment 1 by the way of laser welding to be had on the bottom surface of through hole 11.In the present embodiment, two corners of a side of lower shell fragment 1 weld together with a terminal 2 respectively.
As shown in Figure 5, Figure 6, this utility model uses laser welding to realize second embodiment of the voice coil motor structure connected, and it includes lower shell fragment 1 ' and terminal 2 '.
Described lower shell fragment 1 ' offers a through hole 11 ' on the opposite face of terminal 2 '.
The end face of described terminal 2 ' upwards one boss 21 ' of projection, this boss 21 ' is positioned at the underface of the through hole 11 ' of lower shell fragment 1 ', and the internal diameter of described lower shell fragment 1 ' through hole 11 ' is less than the external diameter of boss 21 '；So that the end face of the bottom surface of lower shell fragment and terminal well fits together.Terminal 2 ' is fixed on by the way of laser welding lower shell fragment 1 ' have on the bottom surface of through hole 11 '.
In this embodiment, the one in the shapes such as generally circular in shape, square, the triangle of described lower shell fragment 1 ' through hole 11 '；One in the shapes such as generally circular in shape, square, the triangle of described terminal 2 ' end face convex platform 21 '.
Emphasis of the present utility model is that lower shell fragment offers through hole on the opposite face of terminal.
The above, it is only this utility model preferred embodiment, therefore can not limit, with this, the scope that this utility model is implemented, the equivalence change i.e. made according to this utility model claim and description with modify, all should still belong in the range of this utility model patent contains.
