The working principle of the multi-channel signal transmission device in embodiment 1 is that, because the height of the first guiding circular arc 12133 is higher than that of the contact spring arm 12121, in the process of connecting the base head with the base, the base head fixing piece 22 will contact with the first guiding circular arc 12133 and then contact with the contact spring arm 12121, i.e. the base head fixing piece 22 will be guided by the first guiding circular arc 12133 and then clamped between the contact spring arms 12121, thereby avoiding the damage to the contact spring arm 12121 caused by the impact of the base head on the contact spring arm 12121. The second base fixing portion 1214 is disposed above the contact spring arm 12121, so that the second base fixing portion 1214 can further avoid the base head from directly contacting the contact spring arm 12121 during the process of connecting the base head to the base.
Meanwhile, as shown in fig. 11 and 12, since the second introduction circular arc 222 and the third introduction circular arc 223 are provided on the base fixing portion 221, the second introduction circular arc 222 and the third introduction circular arc 223 can also facilitate the smooth introduction of the base fixing member 22 into the two-contact spring arms 12121.
