Detailed Description
The utility model is further illustrated with reference to the following specific examples and the accompanying drawings.
As shown in fig. 1-4, a conductive spring for a battery cover comprises a first tower spring 1 and a second tower spring 2 which are arranged side by side, wherein the first tower spring 1 and the second tower spring 2 have the same shape and size, and are tower springs with small upper parts and large lower parts, and the upper end surfaces of the tower springs are parallel to the lower end surfaces of the tower springs; the upper end face ring 11 of the first tower spring and the upper end face ring 21 of the second tower spring are both non-closed rings with notches, the notches are arranged oppositely, and the middle parts of the notches are connected through a snake-shaped connecting rod 3; the snake-shaped connecting rod 3, the first tower spring upper end face ring 11 and the second tower spring upper end face ring 21 are positioned in the same plane; the end face ring connecting rods 31 at the two ends of the snake-shaped connecting rod 3 are linear short rods, the projections of the end face ring connecting rods 31 and the upper end face ring 11 of the first tower spring 1 in the axial lead direction of the first tower spring are positioned in the inner ring range of the second ring above the first tower spring 1, and the projections of the other end face ring connecting rods 31 and the upper end face ring 21 of the second tower spring in the axial lead direction of the second tower spring 2 are positioned in the inner ring range of the second ring above the second tower spring 2; the main body of the snake-shaped connecting rod 3 is formed by connecting 5 straight rods which are arranged into a fold line end to end; the included angles between the straight rods of the main body of the snake-shaped connecting rod 3 are equal and are 40 degrees; the bent part of the snake-shaped connecting rod 3 is provided with arc transition. The first tower spring 1, the second tower spring 2 and the snake-shaped connecting rod 3 are of an integral structure.
The outer diameter of the upper circle of the spiral body of the first tower spring 1 or the second tower spring 2 is smaller than the inner diameter of the lower circle. Therefore, when the upper end of the first tower spring 1 or the upper end of the second tower spring 2 is pressed, the upper circle of the tower spring does not overlap the lower circle when moving downwards, and the stroke of downward compression deformation is longer.
The conductive spring designed by the utility model is an integrated structure formed by two tower springs (a first tower spring 1 and a second tower spring 2) through a snake-shaped connecting rod 3, meanwhile, the upper end surface of each tower spring and the snake-shaped connecting rod 3 are positioned in the same plane, and the integrated structure of the spring has better stability relative to two independent springs (connected through a soft lead wire), and the upper half section of each spring is easy to deviate from the axis when the two independent springs are used for a longer time, so that the deformation direction of the spring cannot be vertical to the contact surface of a battery, and thus, the independent spring deforms seriously to cause poor conductive effect. The springs with the integrated structure are not easy to deviate and deform in the respective axial lead direction, the upper end faces of the two tower springs are connected together through the snake-shaped connecting rod 3 in the middle, and the snake-shaped connecting rod 3 has deformation capacity and is easy to recover after being subjected to lateral impact force, so that the service life of the springs can be prolonged; simultaneously can increase the area of contact with the battery effectively again, because snakelike connecting rod 3 and first tower spring up end circle 11, second tower spring up end circle 21 lie in the coplanar, planar stability and snakelike connecting rod 3's end circle connecting rod 31 setting can both increase the area of contact with the battery effectively, consequently the electrically conductive connection is more stable. Therefore, the spring with the integrated structure can be particularly suitable for the battery cover with larger vibration, and the durability and the conductive stability of the conductive spring can meet the requirements.
The above embodiments are merely preferred embodiments of the present invention, which are intended to be illustrative and not limiting, and any changes, substitutions, combinations, simplifications, modifications, etc. made by those skilled in the art without departing from the spirit and principle of the present invention shall be included in the scope of the present invention.
