Preferably, the height of the fourth notch 1172 may be greater than the height of the second limiting arm 1171, so that the second limiting arm 1171 does not protrude from the second protection arm 117 along the height direction of the soldering portion 11, thereby reducing the height of the electrical connection spring 100. Of course, the length, width, height and shape of the fourth notch 1172 are not limited in the present utility model, as long as the use of the electrical connection spring 100 is not affected, for example, the length of the fourth notch 1172 may be greater than the length of the second limiting arm 1171, so that the second limiting arm 1171 can be bent and formed conveniently in the production process.

Further, the front end of the first contact portion 123 (the end close to the first elastic arm 122) may extend obliquely in a direction away from the welding portion 11, so as to be conveniently abutted against an external device; the rear end of the first contact portion 123 (the end far from the first elastic arm 122) may be bent and formed in a direction approaching the welding portion 11, and when the external device is pressed against the first contact portion 123, the rear end of the first contact portion 123 abuts against the welding portion 11, so that the problem that the first connecting arm 12 is pressed down too much can be avoided. Also, the front end of the second contact portion 133 (the end close to the second elastic arm 132) may be inclined to extend in a direction away from the welding portion 11, thereby facilitating abutment with external equipment; the rear end of the second contact portion 133 (the end far from the second elastic arm 132) may be bent and formed in a direction approaching the welding portion 11, and when the external device is pressed against the second contact portion 133, the rear end of the second contact portion 133 abuts against the welding portion 11, so that the problem that the second connection arm 13 is pressed down too much can be avoided.

Preferably, the projections of the first elastic arm 122, the first contact portion 123, the second elastic arm 132, and the second contact portion 133 on the front surface 111 of the welding portion 11 fall on the welding portion 11, so that the length and the width of the electrical connection spring sheet 100 can be reduced, thereby saving space and meeting the current small-size requirements of users on electronic devices.

Preferably, the first connecting arm 12 and the second connecting arm 13 may be provided with metal plating layers, so as to improve the electrical conductivity of the first contact portion 123 and the second contact portion 133, and increase the oxidation resistance, wear resistance, and corrosion resistance of the first connecting arm 12 and the second connecting arm 13.
