Optionally, the angle β between the second electrical connector sub-portion 32 and the third electrical connector sub-portion 33 ranges from 120 β to 160 °.
Specifically, the angle β between the second electrical connector sub-portion 32 and the third electrical connector sub-portion 33 may be, but is not limited to, 120 °, 125 °, 130 °, 135 °, 140 °, 145 °,150 °, 155 °, 160 °, etc. The angle β between the second electrical connector portion 32 and the third electrical connector portion 33 is too small, which reduces the elasticity of the second electrical connector portion 30, and is not beneficial to the electrical connection between the second electrical connector portion 30 and the housing, and the angle β between the second electrical connector portion 32 and the third electrical connector portion 33 is too large, which reduces the contact area between the third electrical connector portion 33 and the housing, and is not beneficial to the stability of the electrical connection between the electrical connector 100 and the housing when the electrical connector 100 is mounted on the housing.
Alternatively, the angle θ between the first electrical connector portion 31 and the second electrical connector portion 32 ranges from 140 θ+.ltoreq.170 °.

Optionally, the thickness of the first electrical connection 10 ranges from 0.18mm to 0.22mm. The thickness of the second electrical connection is in the range of 0.18mm to 0.22mm.
