[0037] The wire connection assembly 4 includes a wire fixing unit with a T-shaped mounting hole 403, a rotating unit, and a locking unit. The wire fixing unit is used to realize the clamping and fixing of the wire end. The rotating unit is used to realize the rotation of the wire fixing unit so that the T-shaped mounting hole 403 in the wire fixing unit faces the front end of the housing body 101, so that the wire end can be inserted into the T-shaped mounting hole 403. The locking unit is used to fix the vertical state and the inclined state of the wire fixing unit.

[0038] The wire fixing unit also includes a rotating connection end 401, a T-shaped mounting hole 403, a T-shaped metal column 405, and an inverted V-shaped metal spring 406;

[0039] The rotating connection terminal 401 is arranged inside the rotating movable groove 105, the T-shaped mounting hole 403 is opened at the top of the rotating connection terminal 401 and passes through the bottom of the rotating connection terminal 401, and the T-shaped metal column 405 is vertically slidably connected to the inside of the T-shaped mounting hole 403 and protrudes to the bottom of the rotating connection terminal 401 and fits with the rectangular metal sheet 2;

[0040] The inverted V-shaped metal springs 406 are symmetrically fixed on the top of the T-shaped metal column 405 and located inside the T-shaped mounting hole 403. When the wire is inserted into the T-shaped mounting hole 403, the two inverted V-shaped metal springs 406 are squeezed and deformed. The deformed inverted V-shaped metal springs 406 are tightly attached to the outside of the wire to fix the wire, and the wire is electrically connected to the rectangular metal sheet 2 through the inverted V-shaped metal springs 406 and the inverted V-shaped metal springs 406.

[0041] The rotating unit includes a rotating column 402 and a pressing notch 407;

[0042] The rotating column 402 is symmetrically fixed on both sides of the outer wall of the rotating connection terminal 401, and the inner wall of the rotating movable groove 105 is provided with rotating holes 106. The rotating connection terminal 401 is rotatably connected to the rotating hole 106 through the rotating column 402 to realize the rotation connection with the shell body 101; the pressing notch 407 is opened at the front end of the rotating connection terminal 401 and is provided with two in the vertical direction, and the two pressing notches 407 are symmetrically distributed with the rotating column 402 as the center; an external tool is inserted into the lower pressing notch 407 to push the rotating connection terminal 401 to rotate with the rotating column 402 as the center, so as to realize the rotation of the T-shaped mounting hole 403 toward the front end of the shell body 101; an external tool is inserted into the upper pressing notch 407 to push the rotating connection terminal 401 to rotate with the rotating column 402 as the center, so as to realize the rotation of the T-shaped mounting hole 403 to the vertical upward state;

[0043] The locking unit includes a raised extrusion block 404;

[0044] The protruding extrusion blocks 404 are symmetrically formed at both ends of the inner wall of the T-shaped mounting hole 403, and two inverted V-shaped metal springs 406 are respectively attached to the end faces of the two protruding extrusion blocks 404, and an arc portion matching the outer wall of the protruding extrusion block 404 is formed at the contact position between the inverted V-shaped metal spring 406 and the protruding extrusion block 404;

[0045] The second locking holes 3 are symmetrically formed at the upper and lower ends of the rectangular metal sheet 2, and the arc-shaped inner wall of the rotating movable groove 105 is provided with a first locking hole 107;

[0046] The bottom of the T-shaped metal column 405 is inserted into the second locking hole 3 to fix the vertical state of the rotating connection end 401. When the rotating connection end 401 rotates, the T-shaped metal column 405 is forced to shrink so that the inverted V-shaped metal spring 406 squeezes the protruding squeezing block 404, and the inverted V-shaped metal spring 406 will be deformed;

[0047] When the T-shaped metal column 405 is aligned with the first locking hole 107 , it will be stuck into the first locking hole 107 under the deformation and restoring elastic force of the inverted V-shaped metal spring piece 406 , so as to fix the tilted state of the rotating connecting end 401 .

[0048] In this embodiment: it should be noted that: the initial state of the two rotating connection ends 401 is a vertical state, and the two T-shaped mounting holes 403 are respectively facing upward and downward;

[0049] When it is necessary to install the wire, taking the rotating connection terminal 401 at the upper end of the housing body 101 as an example, the operation steps are as follows:

[0050] Insert an external tool into the lower pressing notch 407 and squeeze it. At this time, the rotating connection end 401 located below the connecting column 402 is pushed and rotates toward the inside of the rotating movable groove 105. The bottom spherical surface of the T-shaped metal column 405 is squeezed and shrinks toward the inside of the rotating connection end 401. The T-shaped metal column 405 pushes the inverted V-shaped metal spring 406 to move upward. The inverted V-shaped metal spring 406 is squeezed from the protruding squeezing block 404 and deformed. The contraction of the T-shaped metal column 405 separates it from the second locking hole 3, so that the rotating connection end 401 can rotate smoothly.

[0051] When the rotating connection end 401 rotates until the T-shaped metal column 405 is aligned with the first locking hole 107, the T-shaped metal column 405 will move and snap into the first locking hole 107 under the elastic force of the inverted V-shaped metal spring sheet 406. At this time, the push can be stopped, and the rotating connection end 401 is in an inclined state as a whole, and the end of the T-shaped mounting hole 403 faces the front end of the shell body 101. At this time, the T-shaped metal column 405 is disconnected from the rectangular metal sheet 2;

[0052] Then, the end of the wire to be installed is inserted into the T-shaped installation hole 403, and the wire end will squeeze the top fold of the inverted V-shaped metal spring 406 to deform it. The inverted V-shaped metal spring 406 fits tightly to the outside of the wire end under its own elastic force, thus achieving the preliminary installation of the wire end;

[0053] Then, an external tool is inserted into the upper pressing notch 407 and pushed. At this time, the part of the rotating connection terminal 401 located above the rotating column 402 is pushed upward and rotated. At this time, the rotating connection terminal 401 rotates from an inclined state to a vertical state, and at this time, the bottom of the T-shaped metal column 405 is stuck in the second locking hole 3. At this time, the position of the T-shaped metal column 405 is in a semi-contracted state compared to the state when it is stuck in the first locking hole 3. That is, at this time, the inverted V-shaped metal spring piece 406 is further deformed and fits the wire end, so that the wire end is further tightened, and the wire end is electrically connected with the rectangular metal sheet 2 through the inverted V-shaped metal spring piece 406 and the T-shaped metal column 405;

[0054] The operation of connecting the wire to the rotating connection terminal 401 at the lower end of the housing body 101 is the same as the above operation steps, except that the pressing notch 407 is in the opposite direction up and down;

[0055] It should be noted that: when the terminal block 1 is used, multiple terminals are horizontally distributed and used together. By rotating the rotating connecting end 401 so that the T-shaped mounting hole 403 faces the front end of the shell body 101, the insertion operation of the wire is more accurate and the situation of incorrect holes is effectively avoided.

[0056] Please refer to Figures 1 to 4 The bottom of the T-shaped metal column 405 is a spherical structure, and the distance between the second locking hole 3 and the center of the rotating column 402 is smaller than the distance between the first locking hole 107 and the center diameter of the rotating column 402.

[0057] In this embodiment: through this structure, when the T-shaped metal column 405 is inserted into the second locking hole 3, compared with the state when it is inserted into the first locking hole 3, the T-shaped metal column 405 is in a semi-contracted state, that is, at this time, the inverted V-shaped metal spring piece 406 is further deformed and fits the wire end, thereby further tightening the wire end and ensuring the stable connection of the wire end.

[0058] Please refer to Figures 2-3 A protrusion is formed at one end of the rectangular metal sheet 2, and a groove for the protrusion to engage is formed at one end of the inner wall of the connecting straight groove 104.

[0059] In this embodiment: this structure allows the rectangular metal sheet 2 to remain fixed and avoid displacement.

[0060] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
