[0037] 第一弹簧200的两端和第二弹簧300的两端分别与线路板100以及电池400的正极和负极相接触。 [0037] The ends of the first spring 200 and second spring ends 300 are in contact with the positive and negative wiring board 100 and the battery 400.

[0038] 优选地,在本实施例中,第一弹簧200的塔底端与线路板的正极相连,第一弹簧200的塔头端与电池的正极相连;第二弹簧300的塔头端与线路板的负极相连,第二弹簧300的塔底端与电池的负极相连。 [0038] Preferably, in the present embodiment, the bottom end of the positive column of the circuit board 200 is connected to first spring, the first end of the first column of the spring 200 is connected to the positive electrode of the battery; column head end 300 and the second spring circuit board connected to the negative electrode, the tower bottom of the second spring 300 is connected to the negative electrode of the battery.

[0039] 优选地,在本实施例中,第一弹簧200和第二弹簧300均固定于线路板的端面上;使第一弹簧200和第二弹簧300的固定更稳定,使导电结构的组装更方便。 [0039] Preferably, in the present embodiment, the first spring 200 and second spring 300 are fixed to the end face of the circuit board; the first spring 200 and second spring 300 more stable fixing of the conductive structure of the assembly more convenient.

[0040] 进一步地,第二弹簧300的塔头端的直径小于线路板100的直径,第二弹簧300的塔底端的直径小于电池400的端面的直径。 [0040] Further, the diameter of the tower head end of the second spring 300 is smaller than the diameter of the circuit board 100, the diameter of the bottom end of the column spring 300 is smaller than the second diameter of the end surface of the battery 400.

[0041] 进一步地,第一弹簧塔底端的直径小于第二弹簧300的塔头端的直径; [0041] Further, the diameter of the bottom of the column is less than the diameter of the first spring end of the second spring tower head 300;

[0042] 更进一步地,由于第二弹簧300塔头端的直径小于线路板100的直径,塔底端的直径小于电池400端面的直径;这样,就使尺寸较大的第二弹簧300可以有效地与线路板100和电池400相接触,由于第一弹簧200的尺寸比第二弹簧300小,因此,可以保证第一弹簧200也可以有效地与线路板100和电池400相接触,产生导电作用。 [0042] Still further, since the diameter of the head end of the second spring 300 is smaller than the diameter of the column wiring board 100 having a diameter smaller than the diameter of the column bottom end surface 400 of the battery; Thus, the larger the size of the second spring 300 can be effectively and circuit board 100 and the battery contact 400, since the size of the first spring 200 is smaller than the second spring 300, and therefore, can ensure that the first spring 200 can be effectively brought into contact with the circuit board 100 and battery 400, to produce a conductive effect.

[0043] 优选地,在本实施例中,第二弹簧300环绕在第一弹簧200的外侧,并与第一弹簧200相分离; [0043] Preferably, in the present embodiment, the second spring 300 around the outside of the first spring 200 and the spring 200 separated from the first phase;

[0044] 进一步地,在本实施例中,第一弹簧200端面的中心和第二弹簧300端面的中心与线路板的中心在同一直线上;使第一弹簧200和第二弹簧300受力均匀,且弹性变形的方向—致。 [0044] Further, in the present embodiment, the center 300 of the center of the end face 200 of the first end surface and second springs and the center of the circuit board on the same line; the first spring 200 and second spring 300 force uniform , and the direction of the elastic deformation - induced.

[0045] 更近一步地,由于第一弹簧塔底端的直径小于第二弹簧300的塔头端的直径,所以第一弹簧200完全小于第二弹簧300,因此,可以保证当第二弹簧300套在第一弹簧200的外侧时,第二弹簧300和第一弹簧200之间完全分离,且由于两个弹簧同心设置,避免了在压缩过程中发生偏离而导致的相互接触,保持了正常的导电。 [0045] step closer, since the diameter of the bottom end of the first spring is smaller than the column diameter of the second spring end 300 of the tower head, the first spring 200 second spring 300 is less than the full, and therefore, can ensure that when the second spring 300 in the sleeve the outside of the first spring 200 and second spring 300 and first spring 200 are completely separated, and since two springs disposed concentrically, to avoid contact with each other resulting in deviation occurs in the compression process, maintaining a normal conduction.

[0046] 优选地,在本实施例中,第一弹簧200和第二弹簧处于自然状态时的长度近似相等;使第一弹簧200和第二弹簧300的受到的压缩力更均等,使导电结构更可靠。 [0046] Preferably, in the present embodiment, the first spring and the second spring 200 is in a natural state length approximately equal; the first spring 200 and second spring compression force more uniformly by 300, conductive structure more reliable.
