A first connection terminal 3 is provided inside the first connector 1, and a second connection terminal 4 is provided inside the second connector 2. The first connection terminal 3 is entirely located inside the first connector 1, while a portion of the second connection terminal 4 is located inside the second connector 2 and another portion is located inside the first connector 1, and contacts the first connection terminal 3 to achieve connection.

[0025] The first connecting terminal 3 is provided with a first column end 5, the second connecting terminal 4 is provided with a contact hole 6 for accommodating the first column end 5, and the first connecting member 1 and the second connecting member 2 are connected via a detachable structure.

[0026] The first connection terminal 3 is composed of a first column end 5, a first connection section 7 and a first wrapping portion 8. A through hole 9 is provided in the middle of the blocking portion 11, and the first column end 5 is arranged in the through hole 9. The diameter of the first connection section 7 is smaller than the diameter of the first column end 5. The first wrapping portion 8 is used to wrap and connect the first wire 10. After the first wrapping portion 8 wraps the first wire 10, it can pass through the through hole 9 in the middle of the blocking portion 11, and the diameter of the through hole 9 matches the diameter of the first column end 5.

[0027] The second connection terminal 4 is composed of a second column end 12, a second connection section 13 and a second wrapping portion 14. The contact hole 6 is located in the second column end 12. A flip sleeve 15 is provided outside the second column end 12. A gap 16 is left between the flip sleeve 15 and the second column end 12. An elastic arm 17 is located on the flip sleeve 15, and the elastic arm 17 is opened toward the second wrapping portion 14.

[0028] The diameter of the second connecting section 13 is smaller than the diameter of the second cylindrical end 12. The second wrapping portion 14 is used to wrap the second wire 18. When the first connecting terminal 3 and the second connecting terminal 4 are plugged in, the first wire 10 and the second wire 18 can be connected.

[0029] A limiting chamber 19 for accommodating the elastic arm 17 is provided in the middle of the first connecting member 1 . The elastic arm 17 contacts the inner wall of the limiting chamber 19 to prevent the second connecting terminal 4 from being separated from the first connecting member 1 .

[0030] The first connecting member 1 is composed of a threaded portion 20, a limiting portion 21 and a first rod body 22. The limiting chamber 19 is located in the middle of the limiting portion 21. The first rod body 22 is provided with a first chamber 23 and a second chamber 24 inside. The first chamber 23 and the second chamber 24 are separated by a blocking portion 11.

[0031] A shrink hole 25 is provided in the middle of the threaded portion 20, and the shrink hole 25 is used to apply pressure to the elastic arm 17, and at the same time, the elastic arm 17 is deformed downward by the inner wall of the shrink hole 25, and the elastic arm 17 is kept to pass through the shrink hole 25 and enter the limit chamber 19. However, the inner diameter of the limit chamber 19 is larger than the inner diameter of the shrink hole 25, and the elastic arm 17 is blocked by the inner wall of the limit chamber 19, and the second connection terminal 4 cannot be moved out of the limit chamber 19.

[0032] The second connecting member 2 is composed of a mounting portion 26 and a second rod body 27 . An internal thread 28 matching with the threaded portion 20 is provided in the middle of the mounting portion 26 . A third chamber 29 is provided inside the second rod body 27 .

[0033] An elastic member 30 is disposed in the contact hole 6 and contacts the first column end 5. The elastic member 30 is used to apply a reverse force to the second connection terminal 4, so that the elastic arm 17 is bent and placed in the limit chamber 19.

[0034] The first connecting member 1 is provided with a first wire hole 31 , and the second connecting member 2 is provided with a second wire hole 32 .

[0035] When in use, the first wire body 10 is first passed through the first wire hole 31 to connect with the first connection terminal 3, and the second wire body 18 is passed through the second wire hole 32 to connect with the second connection terminal 4. Then the elastic member 30 is placed in the contact hole 6, and then the first connection terminal 3 and the second connection terminal 4 are inserted into each other to keep the first connection terminal 3 and the second connection terminal 4 in contact. Then the first connection terminal 3 is placed in the through hole 9 of the blocking portion 11 to position it so that the first connection terminal 3 and the second connection terminal 4 are located between the first connection member 1 and the second connection member 2.

[0036] Then, the first connector 1 is inserted toward the direction of the second connector terminal 4, and the shrink hole 25 is kept to compress the elastic arm 17, so that the elastic arm 17 enters the limit chamber 19 to block the second connector terminal 4. At this time, the elastic member 30 is in a compressed state. Then, the internal thread 28 on the second connector 2 is connected to the threaded portion 20.

[0037] When the first connector 1 is plugged into the first connecting terminal 3 , the connecting portion between the flip sleeve 15 and the second cylindrical end 12 will contact the c-surface of the blocking portion 11 , limiting the further movement of the first connector 1 , indicating that the elastic arm 17 has entered the limit chamber 19 .

[0038] The surface b of the first connecting member 1 is used to block the first connecting terminal 3 , and the surface a of the second connecting member 2 is used to block the second connecting terminal 4 .
