Embodiment 1
[0025] Such as Figure 1-3 As shown, the electrical connection device of the Christmas light tree in this embodiment includes an upper connection seat 1 and a lower connection seat 2, the upper connection seat 1 is provided with a columnar first electrode 3, and the lower connection seat 2 is provided with a There is an arc-shaped second electrode 4 in contact with the first electrode 3, and the upper connecting seat 1 is also provided with a spring force to make the first electrode 3 press against the second electrode 4. Elastic device 5. Point-to-surface contact is formed by the columnar first electrode 3 and the arc-shaped second electrode 4, and an elastic force is provided to make the first electrode 3 press against the first electrode 3 through the elastic device 5 arranged in the upper connection seat 1. The two electrodes 4 greatly improve the reliability of the electrical connection, and can realize high and low voltage universal use.
[0026] Such as figure 2 , ...
Embodiment 2
[0031] Such as Figure 6As shown, the overall structure of this embodiment is the same as that of Embodiment 1, the difference is that the buckle aisle 621 is arranged at the end of the slot 62, and the upper connecting seat 1 is opposite to the lower connecting seat 2 They can only be turned in one direction, and they can be fixed to each other after turning. At this time, the arc-shaped pole plate 41 of the second electrode 4 is shorter than the length of the arc-shaped pole plate 41 in Embodiment 1. When the buckle 61 is inserted into the slot 62 from the buckle channel 621 , the first The contact end 32 of the electrode 3 may not contact the arc-shaped plate 41 of the second electrode 4. When the upper connecting seat 1 gradually rotates to the limit position of the end of the slot 62, the contact end of the first electrode 3 32 against the arc-shaped plate 41 of the second electrode 4 .
Embodiment 3
[0033] Such as Figure 7 As shown, the overall structure of this embodiment is the same as that of Embodiment 1, the difference is that the elastic device 5 is a tension spring, and the tension spring is arranged on the bottom surface 111 of the accommodating groove 11 and the protruding ring of the first electrode 3 31 between the lower surfaces.
