The base 1 defines a fitting hole 10, into which the adapter head 2 is inserted and thereby attached onto the base 1. The fitting hole 10 is coaxial with the base 1. A first mounting slot 13 is defined at the inner wall of the base 1 and extends downwards from the top of the base 1. A second mounting slot 14 extending upwards from the bottom of the base 1 is provided, and is corresponding to and located outside of the first mounting slot 13. A first hollow out opening 15 extending downwards from the top of base 1 is provided on the outside of the second mounting slot 14. In detail, the first hollow out opening 15 is defined at the outer wall of the base 1, in other words, the second mounting slot 14 is exposed exterior via the first hollow out opening 15. The two base copper terminals 3 are inserted into the first mounting slot 13 and the second mounting slot 14, respectively. A first fixing block 5 mounted on the base 1 is provided at the bottom end of the second mounting slot 14. After the base copper terminals 3 are mounted in the first mounting slot 13 and the second mounting slot 14, the upper end of the base copper terminal 3 in the first mounting slot 13 is exposed in the fitting hole, and the upper end of the base copper terminal 3 in the second mounting slot 14 is exposed in the exterior via the first hollow out opening 15. This facilitates the contact between the base copper terminals 3 and the adapter head copper terminals 8 of the adapter head 2. The first fixing block 5 is installed below the second mounting slot 14 to fix the base copper terminal 3 therein, thereby preventing the base copper terminal 3 falling out therefrom.
The adapter head 2 includes a fitting portion 201 at the bottom end thereof, and the fitting portion 201 is exactly installed in the fitting hole 10 of the base 1. The assembling hole 21 is a counter bored hole extending downward from the top end of the adapter head 2. A person skilled in the art understands that the counter bored hole means a step hole. A third mounting slot 22 is defined in the adapter head 2 and extends downwards from the top thereof. A second hollow out opening 23 is defined beside and communicated with the third mounting slot 22. The base copper terminal 3 in the first mounting slot 13 will be exposed in the second hollow out opening 23. A protrusion 24 is provided at the outer wall of the adapter head 2, and extends downward below the first hollow out opening 15. The protrusion 24 includes an extending portion 240 spaced opposite to the fitting portion 201. A fourth mounting slot 241 is defined in the protrusion 24, and extends from top to bottom thereof. A second fixing block 6 is mounted on the protrusion 24 and is defined at the top end of the fourth mounting slot 241. The fourth mounting slot 241 is parallel to the third mounting slot 22, and is spaced opposite to the second hollow out opening 23.

The third mounting slot 22 and the fourth mounting slot 241 are corresponding to and located adjacent to the first mounting slot 13 and the second mounting slot 14, respectively. The adapter head copper terminals 8 each have contacts on a bottom end thereof. After the adapter head copper terminals 8 are mounted in the third mounting slot 22 and the fourth mounting slot 241, contacts of the adapter head copper terminals 8 are in electrically communication with the base copper terminals 3, respectively. In detail, the adapter head copper terminal 8 in the third mounting slot 22 is positioned inside and electrically communicated with the base copper terminal 3 in the first mounting slot 13, the adapter head copper terminal 8 in the fourth mounting slot 241 is outside the base copper terminal 3 in the second mounting slot 14 and is electrically connected thereto. The second fixing block 6 is configured for fixing the adapter head copper terminal 8 above the fourth mounting slot 241.

Two adapter head copper terminals 8 are spaced opposite to and parallel with each other. The fitting portion 201 is exactly engaged in the fitting hole 10 of the base 1, the adapter head copper terminal 8 in the third mounting slot 22 is in contact with the base copper terminal 3 in the first mounting slot 13, and the adapter head copper terminal 8 in the fourth mounting slot 241 is in contact with the base copper terminal 3 in the second mounting slot 14. The base copper terminals 3 are located between the two adapter head copper terminals 8. The base copper terminals 3 and the adapter head copper terminals 8 are parallel, with an axial of the fitting hole 10, and the fitting hole 10 is coaxial with the fitting portion 201.
The upper end of the adapter head copper terminal 8 mounted in the third mounting slot 22 is bent and snapped onto the step surface 25 of the assembling hole 21. The plug wire 7 passes through the plug wire hole 27 and is in contact with the bent upper end of the adapter head copper terminal 8. In this way, it is convenient for the plug wire 7 to be in contact with the adapter head copper terminal 8, and the disassembly of the adapter head copper terminal 8 is facilitated, it can be taken out directly through the bent portion thereof.
An annular baffle 9 is disposed in the assembling hole 21 and is detachably connected with the adapter head 2. The design of the annular baffle 9 can protect the exposed portion of the adapter head copper terminal 8 in the assembling hole 21 of the adapter head 2.
The outer wall of the base 1 and the adapter head 2 are respectively provided with a connector wire fixing part 16 and a plug wire fixing part 26.

One end of the plug wire 7 is inserted into the plug wire hole 27 and is electrically connected with the adapter head copper terminal 8, and the other end of the plug wire 7 is outside the adapter head 2 and hung on the plug wire fixing part 26. In this way, it is convenient to fix the wires.
A bulgy rib can be defined at the adapter head 2, and a recess 17 that fits with the bulgy rib can be defined in the base 1. When the adapter head 2 engages with the base 1, the rotation between the adapter head 2 and the base 1 can be prevented by the cooperation of the bulgy rib and the recess 17.
The base 1, the connector plug wires 4, the base copper terminals 3, and the first fixing block 5 constitute the base assembly 100. The adapter head 2, the plug wires 7, the adapter head copper terminals 8, and the second fixing block 6 constitute the adapter head assembly 200.

According to the actual situation, multiple adapters can be used to connect with multi-sections of tree trunks. Then during the latter circuit connection period, the corresponding adapter can be found directly on the tree trunk, and the circuit can be connected to light up the lighting on the Christmas tree, by connecting the connector wires and the plug wires with the corresponding components. In detail, the base 1 defines base copper terminals 3, the adapter head 2 defines adapter head copper terminals 8, which are in contact with the base copper terminals 3.
