Detailed Description

The following are specific embodiments of the present invention and are further described with reference to the accompanying drawings, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 to 2, the solder terminal independent mounting structure includes:

the four corners of the base 1 are respectively provided with a horizontal positioning surface 10 which is positioned on the same horizontal plane; the base 1 is formed by injection molding, the mode is high in efficiency and good in product consistency, the four horizontal positioning surfaces 10 can be ensured to be positioned on the same horizontal plane, and the reed mounting precision is improved.

The reed 2 is a lower reed in the embodiment and comprises two pieces; which functions as power supply and elastic force recovery, etc.

Each reed 2 is respectively and snugly fixed on the corresponding horizontal positioning surface 10 through two outer corner pieces 20, and the reeds 2 are used for power supply coils;

the structure of the outer corner piece 20 is generally triangular, and of course, the shape can be set according to the shape of the base to prevent installation interference.

Two independent rigid solder terminal blocks 4 are provided, each cooperating with an outer corner piece 20 of each spring piece 2. After the spring plate 2 is fixed on the base 1, two rigid welding terminal blocks 4 are respectively and snugly arranged on the upper surfaces of two outer corner pieces 20 of the spring plate 2. The horizontal rigidity strength of the rigid welding terminal block 4 is greater than or equal to that of the outer corner piece 20

As shown in fig. 3, when the solder terminal independent mounting structure of the present invention is further mounted with the carrier, the coil, the magnet and the upper spring plate, the rigid solder terminal block 4 is left empty above, so that two of the four outer corner plates of the spring plate 2 have solder terminals thereon, and the other two outer corner plates have no component thereon, and the mounting of the other components is not affected. The upper parts of the four outer corner pieces of the lower reed of the self body are vacant.

The rigid solder terminal block 4 has a terminal extension pin 42, and the terminal extension pin 42 extends from the rigid solder terminal block 4 but is not in the same plane as the rigid solder terminal block 4. The terminal extension PIN 42 serves as a PIN for connection to an external power source. In the embodiment, the terminal extension PIN 42 is perpendicular to the rigid soldering terminal block 4, as shown in fig. 4 and 5, a through hole 12 is formed in one side of the base 1 close to the rigid soldering terminal block 4, and the terminal extension PIN just passes through the through hole 12 and then is exposed outside the base, so that the terminal extension PIN serving as a PIN is conveniently connected externally. As shown in fig. 5, the first base support leg 7 is further provided on the side of the terminal extension leg 42 extending out from the base, and since there are two rigid soldering terminal blocks 4, there are two first base support legs 7 respectively located at two ends of one side of the base. And a second base supporting leg 8 is also arranged on the other parallel side opposite to the side where the two first base supporting legs 7 are arranged, and the two first base supporting legs 7 and the second base supporting leg 8 are used for supporting a base or are used for connecting when other components are externally connected, so that the bases are kept on the same plane after the structure is installed. Meanwhile, the first base supporting leg 7 on the side of the terminal extending leg 42 also has a function of protecting the terminal extending leg 42 as a PIN leg from being deformed by interference. The terminal extension pin 42 may be provided so as not to be perpendicular to the rigid solder terminal block 4, and may be flexibly provided according to the mounting condition of the base in the specific implementation as long as the mounting of other components is not affected.

Because the rigid welding terminal block 4 is arranged after the reed 2 is fixed well, namely after the horizontal arrangement of the reed 2 is ensured, the rigid welding terminal block is welded by two independent rigid welding terminal blocks 4. Thus, the welding does not affect the flatness of the spring plate 2 on the base. The problem that in the existing structure, due to the fact that the metal pieces protruding inwards in the four corners of the base are not flat, the reed is not flat after welding can be effectively solved.

Two positioning pins 11 are respectively arranged at each of four corners of the horizontal positioning surface 10, the positioning pins 11 are perpendicular to the horizontal positioning surface 10, outer corner piece positioning holes 21 and welding terminal positioning holes 43 for the positioning pins 11 to be inserted one by one are respectively arranged on the outer corner piece 20 and the rigid welding terminal block 4, and the outer corner piece positioning holes 21 and the welding terminal positioning holes 43 respectively assist the outer corner piece 20 and the rigid welding terminal block 4 to be accurately and comfortably fixed on the horizontal positioning surface 10 of the base.

As shown in fig. 6 and 7, the thickness of the rigid welding terminal block 4 is greater than that of the outer corner piece 20 located therebelow, so that when the two are welded, the deformation of the outer corner piece 20 caused by welding is minimized, and the stability of the lower spring plate is further facilitated.

As shown in fig. 8 and 9, the method of mounting the lens driving reed mounting structure includes the steps of:

s1, preparing materials:

stamping a plurality of rigid welding terminal blocks 4 which are distributed in pairs in an opposite way and terminal extension pins 42 which are vertically connected with the rigid welding terminal blocks 4 on a first metal plate 8, wherein welding terminal block breaking points 81 are reserved between the rigid welding terminal blocks 4 and the metal plate 8;

preparing a plurality of bases 1 and a plurality of reeds 2;

s2, interval distribution: uniformly distributing a plurality of bases 1 on the same straight line at intervals, wherein the bases 1 are fixed on the same horizontal plane;

s3, fixing the elastic sheet, enabling the second metal plate 9 to be in a horizontal state, enabling the outer corner piece 20 to be aligned with the corresponding horizontal positioning surface 10 of the base 1, and fixing the outer corner piece 20 and the horizontal positioning surface 10 together by using glue;

s4, inserting in an aligning way, namely, enabling the first metal plate 8 to be in a horizontal state and enabling the rigid welding terminal block 4 to be aligned with the corresponding outer corner piece 20, enabling the metal plate 8 to descend and enabling the rigid welding terminal block 4 to be pressed on the upper surface of the corresponding outer corner piece 20, and extending the terminal extending pin vertically connected with the rigid welding terminal block 4 to the outside of the lower surface of the base;

s5, welding, wherein the lower surface of the rigid welding terminal block 4 and the upper surface of the corresponding outer corner piece 20 are fixed together by surface welding;

s6, and the first metal plate 8 and the second metal plate 9 are separated from the rigid welding terminal block 4 and the spring leaf 2 by using the welding terminal block breaking point 81 and the outer corner breaking point 91 as breaking points, respectively, to complete the installation.

The installation method reduces the installation times of the same parts and improves the installation efficiency.

The first metal plate 8 and the stamped and formed rigid welding terminal block 4 are made of the same material and are specifically determined according to actual requirements. The second metal plate 9 is made of the same material as that of the punched reed 2, and is generally made of copper or the like.
