Abstract
The invention discloses a terminal and elastic sheet assembly structure of a voice coil motor, which comprises a lower cover, a terminal and an elastic sheet, wherein the terminal is fixedly arranged on the lower cover, and the elastic sheet is arranged on the top surface of the lower cover and connected with the inner end of the terminal in a sleeving manner. Because the elastic sheet and the terminal are sleeved together in an interference fit mode, a welding procedure is omitted, the tin explosion problem in the welding process is avoided, the assembly is simpler, and the product quality is better. In addition, the two connecting strips are arranged, so that the elastic deformation can be easily realized, and the deformation problem of connection between the elastic sheet and the terminal is avoided.
Description
Technical Field
The present invention relates to a camera device, and more particularly, to a terminal and spring assembly structure for a voice coil motor.
Background
The voice coil motor has the characteristics of high frequency response and high precision. The main principle is that in a permanent magnetic field, the extension position of the spring piece is controlled by changing the direct current of a coil in the motor, so as to drive the spring piece to move up and down. The VCM is widely used by the mobile phone camera to realize the automatic focusing function, and the position of the lens can be adjusted through the VCM to present clear images. Traditional voice coil motor includes parts such as shell fragment, coil, magnet, lower cover, terminal, and the shell fragment links together through the welded mode with the terminal mostly, and in shell fragment and terminal welding process, because contain rosin in the soldering tin, there is the problem of easy explosion tin, in case explode tin, the tin pearl can splash including internal mechanism, influences the part action, reduces the yields.
Disclosure of Invention
The invention aims to provide a voice coil motor terminal and elastic sheet assembling structure which is simple to assemble and high in product quality.
In order to achieve the purpose, the technical solution of the invention is as follows:
the invention relates to a terminal and shrapnel assembly structure of a voice coil motor, which comprises a lower cover, a terminal and a shrapnel, wherein the terminal is fixedly arranged on the lower cover; the inner end of the terminal is provided with a guide surface; the connecting portion that shell fragment and terminal are connected be an annular piece, the inside groove of this annular piece is corresponding with terminal inner shape, size, the inside groove of annular piece cup joints at the inner of terminal and forms interference fit with the inner of terminal, the outside of annular piece is respectively through two connecting strips and this body coupling of shell fragment, on the shell fragment body, offer a scarce hole with the inboard of a connecting strip tie point, should lack the hole and cup joint with the projection of lower cover top surface.
The guide surface at the inner end of the terminal is an inclined surface or an arc surface which is symmetrically arranged at the top.
After the scheme is adopted, the elastic sheet and the terminal are sleeved together in an interference fit mode, so that a welding process is omitted, the tin explosion problem in the welding process is avoided, the risk that rosin is messy when heated during tin soldering, sticky substances of the rosin are sticky to other mechanism parts to influence the poor characteristics of products is completely avoided, the assembly is simpler, and the product quality is better. In addition, the two connecting strips are arranged, so that the elastic deformation can be easily realized, the deformation problem of connection between the elastic sheet and the terminal is avoided, and the working efficiency is improved.
The invention is further described with reference to the following figures and specific embodiments.
Drawings
FIG. 1 is an exploded perspective view of the present invention;
FIG. 2 is an isometric view of the present invention;
fig. 3 is a diagram of the assembly process of the present invention.
Detailed Description
As shown in fig. 1 and 2, the present invention is a terminal and spring assembly structure of a voice coil motor, including a lower cover 1, a terminal 2 and a spring 3.
The terminal 2 is fixedly arranged on the lower cover 1, and the elastic sheet 3 is arranged on the top surface of the lower cover 1 and connected with the inner end of the terminal 2.
The inner end of the terminal 2 has top symmetrically arranged inclined planes 21, which serve as guide surfaces.
The connecting portion that shell fragment 3 and terminal 2 be connected be an annular piece 31, the inside groove 311 of this annular piece 31 is corresponding with terminal 2 inner shape, size, the inside groove 311 cup joints at terminal 2's the inner and forms interference fit with terminal 2's the inner, the outside of annular piece 31 is connected with shell fragment body 33 through two connecting strips 32 respectively, a round hole 34 and a scarce hole 35 are seted up respectively to the inboard on shell fragment body 33, with two connecting strip 32 tie points, should lack hole 35 and the projection 11 of lower cover 1 top surface and cup joint.
Because two connecting strips 32 are arranged at the left side and the right side of the annular sheet 31, when the assembly is carried out, the elastic sheet 3 and the terminal 2 are required to be pressed down and sleeved together, and the deformation caused by uneven stress during pressing down can be avoided, so that the defective rate of the elastic sheet 3 during focusing actuation can be reduced.
As shown in fig. 3, the assembly method of the present invention:
1. the upper hole 35 of the spring plate 3 is sleeved with the convex column 11 on the top surface of the lower cover 1.
2. The annular sheet 31 on the spring sheet 3 is sleeved at the inner end of the terminal 2 under the guidance of the guide surface of the terminal 2 and sleeved together in an interference fit manner.
The invention focuses on: the elastic sheet is connected with the terminal in a sleeved mode.
The above description is only for the preferred embodiment of the present invention, and there are many structures of the elastic sheet connecting portion, so that the scope of the present invention should not be limited by these structures.
