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 Image 6As shown, the overall structure of this embodiment is the same as that of Embodiment 1, the difference is that the buckle channel 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.

Abstract

The invention belongs to the field of Christmas light trees and particularly relates to an electric connection device for a Christmas light tree, which comprises an upper connection seat and a lower connection seat, wherein the upper connection seat is internally provided with column-shaped first electrodes; the lower connection seat is internally provided with arc-shaped second electrodes contacted with the first electrodes; and the upper connection seat is also internally provided with an elastic device for providing an elastic force to enable the first electrodes to abut against the second electrodes. As point and surface contact is formed by the column-shaped first electrodes and the arc-shaped second electrodes, the electric connection reliability is greatly improved, and general use of the Christmas light tree in high and low voltage can be realized; under effects of an external force to the Christmas light tree, full contact of the upper layer and the lower layer is not influenced, and the natural effects of the Christmas light tree are not influenced; and due to corresponding electric connection between multiple groups of first electrodes and second electrodes, diversity of functions of the Christmas light tree is realized.

Description

technical field [0001] The invention belongs to the field of Christmas trees, and in particular relates to an electrical connection device for a Christmas light tree. Background technique [0002] The Christmas tree is one of the important elements of Christmas. The modern Christmas tree originated in Germany, and then gradually became popular all over the world, becoming one of the most famous traditions in Christmas celebrations. [0003] Splicing Christmas trees have a huge market because of their convenient disassembly, packaging and transportation. The spliced ​​Christmas tree is mainly composed of a base, a trunk column, branches and colored lights. The trunk column is set on the base. In order to facilitate storage and transportation, the trunk column is generally composed of two or more hollow tubes. There are tree branches with colored lights on them. However, the existing Christmas tree power connectors generally have the defects of low electrical connection reli...
