The lower cover of the voice coil motor is provided with a plurality of PIN feet, the upper end of each PIN foot is positioned on the upper surface of the upper cover, and the lower end of each PIN foot penetrates through the lower cover and extends out of the lower surface of the lower cover. At present, in the design of the existing voice coil motor, the upper end of the PIN is simple in structure, is in a single-layer sheet shape, and is in an L shape with the lower end at 90 degrees, so that bending deformation is easily caused; meanwhile, when a voice coil motor and other product components are welded in a subsequent customer enterprise, the existing PIN is easy to jack up, and poor performance is caused.
Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
Disclosure of Invention
The invention aims to provide a novel terminal structure of a lower cover of a voice coil motor.
In order to achieve the purpose, the invention adopts the technical scheme that:
a novel terminal structure of a lower cover of a voice coil motor comprises an upper end and a lower end which are integrally bent; wherein,
the upper end comprises a first layer and a second layer which are integrally bent, the first layer and the second layer are both horizontally arranged and are in clearance fit in the vertical direction;
the second layer is positioned below the first layer, the lower end of the second layer is vertically arranged, and the second layer at the upper end of the second layer is connected to the upper part of the lower end of the second layer; and a through hole is arranged on the second layer along the vertical direction to form a horizontally arranged annular structure of the second layer.
The relevant content in the above technical solution is explained as follows:
1. in the above scheme, through inciting somebody to action the upper end is established first layer and the second floor of integrative buckling, and both clearance fit in vertical direction, borrows this design, can promote the structural strength of terminal, and the terminal upper and lower extreme angular deformation that causes when the effectual terminal punching press of avoiding.
2. In the above embodiment, a horizontal ring structure may be formed in the second layer by the arrangement of the through holes. Borrow this design, can effectively increase the area of terminal pad to increase and bury the area underground when the lower cover combines, and then effectively improve and bury the firmness underground, promote the stability that terminal and lower cover combine.
3. In the above scheme, the through hole is a circular hole, and the annular structure is a circular ring structure.
4. In the above scheme, the second layer at the upper end and the lower end are arranged at 90 degrees.
The working principle and the advantages of the invention are as follows:
the invention relates to a novel terminal structure of a lower cover of a voice coil motor, which comprises an upper end and a lower end which are integrally formed; the upper end of the first layer is provided with a first layer and a second layer which are integrally formed, and the first layer and the second layer are horizontally arranged and are in clearance fit in the vertical direction; the second layer is positioned below the first layer, is connected to the upper part of the lower end, and is vertically arranged at the lower end; the second layer is provided with a through hole to form an annular structure.
Compared with the prior art, the terminal structure has the advantages that the structural strength of the terminal is improved, the angle deformation of the upper end and the lower end of the terminal caused by terminal stamping is effectively avoided, the area of the terminal bonding pad is increased, the embedding area when the terminal is combined with the lower cover is increased, the embedding firmness is effectively improved, and the stability of the combination of the terminal and the lower cover is improved.
