[0002] A terminal block is an accessory used to achieve electrical connections and is a type of connector. It's used to facilitate the connection of wires. Existing terminal blocks typically consist of a fixed portion that secures the wire to the terminal block, while the connecting portion connects to other wires or devices. Most existing terminal blocks use screw connections for the fixed portion. Inserting the wire end into the terminal block and repeatedly tightening the screw with a screwdriver secures the wire to the terminal block. This is inconvenient and reduces wiring efficiency.

[0021] A wire entry hole 11 is provided on the side wall of the housing 1 . The wire entry hole 11 is communicated with the inner cavity of the housing 1 . The wire entry hole 11 is used for inserting the power wire 30 .

[0022] The conductive component 2 includes a substrate 21, a contact piece 22 and a foot 23. The substrate 21 is installed in the shell 1. The contact piece 22 is horizontally connected to the upper end of the substrate 21 and is located above the wire entry hole 11. The foot 23 is connected to the lower end of the substrate 21 and is installed at the bottom of the shell 1; it should be noted that when the wire 30 is inserted into the shell 1 from the wire entry hole 11, the wire 30 is located below the contact piece 22.

[0023] The wire clamping spring piece 3 is arranged in the shell body 1 and is horizontally connected to the foot seat 23. The end of the wire clamping spring piece 3 close to the wire entry hole 11 is provided with a first fixed portion 31 and a first deformable portion 32. The first fixed portion 31 is fixed in the shell body 1, and the first deformable portion 32 is connected to the first fixed portion 31 and is tilted upward. The end of the wire clamping spring piece 3 away from the wire entry hole 11 is provided with a second fixed portion 33 and a second deformable portion 34. The second fixed portion 33 is fixed in the shell body 1, and the second deformable portion 34 is connected to the second fixed portion 33 and is tilted upward.

[0024] The trigger switch 4 is rotatably connected in the housing 1 and is located between the first deformable portion 32 and the second deformable portion 34. The rotation axis of the trigger switch 4 is perpendicular to the axis of the wire entry hole 11. One side of the trigger switch 4 is in contact with the second deformable portion 34, and the other side is provided with a convex portion 41 that matches the first deformable portion 32.

[0025] refer to Figure 4 In the normal state, that is, when the wire 30 is not inserted into the housing 1 (or when the wire 30 is not in contact with the trigger switch 4), the first deformable portion 32 is pressed against the bottom of the protruding portion 41 due to the elastic force, and the trigger switch 4 is tightly pressed against the first deformable portion 32 under the elastic push of the second deformable portion 34.

[0026] refer to Figure 5 The method of using the embodiment of the utility model is as follows: the wire 30 is inserted into the housing 1 from the wire entry hole 11, the front end of the wire 30 pushes the trigger switch 4, the trigger switch 4 rotates counterclockwise, the clamping protrusion 41 is separated from the first deformation portion 32, the first deformation portion 32 is instantly released and rebounds upward clockwise to clamp the wire 30, and then a "snap" clamping prompt sound is emitted, reminding the product terminal wiring is completed, which is convenient for the operator to identify, thereby completing the clamping of the wire 30 and making it contact with the contact piece 22. The operator can directly insert various types of (single-core, multi-core) wires 30 without using tools, greatly improving the wiring efficiency.

[0027] refer to Figure 6In this embodiment, the reset button 5 is rotatably connected to the top of the housing 1, and the rotation axis of the reset button 5 is parallel to the rotation axis of the trigger switch 4. A pushing portion 51 is provided at the lower end of the reset button 5. Specifically, a pressing groove 52 is provided on the top of the reset button 5, which facilitates the operator to press down the reset button 5 using a tool such as a screwdriver. When it is necessary to separate the wire 30 from the housing 1, a tool such as a screwdriver can be used to locate and align the pressing groove 52 and press down, or the reset button can be directly pressed down to push the reset button 5 and the pushing portion 51 to rotate clockwise. The pushing portion 51 pushes the first deformable portion 32 downward to deform it close to the locking protrusion 41, thereby loosening the wire 30 and pulling the wire 30 out. In the process of pulling the wire 30 out, the trigger switch 4 rotates clockwise to the initial state under the elastic push of the second deformable portion 34. The locking protrusion 41 locks the first deformable portion 32, and the product terminal is reset, waiting for the next use of the wire.

[0028] In this embodiment, a baffle 42 is vertically mounted on the top of the trigger switch 4. When the wire 30 is inserted into the housing 1 through the wire entry hole 11, the front end of the wire 30 contacts the baffle 42, pushing the trigger switch 4 to rotate. The locking protrusion 41 has a triangular longitudinal cross-section, forming an acute angle with the sidewall of the trigger switch 4, thereby locking the first deformable portion 32.

[0029] In this embodiment, a first positioning column 7 is fixed to the lower inner portion of the shell 1, and a second positioning column 8 parallel to the first positioning column 7 is fixed to the upper inner portion; openings are provided on the trigger switch 4 and the reset button 5, and the trigger switch 4 is rotatably connected to the first positioning column 7 through the opening, and the reset button 5 is rotatably connected to the second positioning column 8 through the opening.

[0030] Specifically, at least two housings 1 are provided. Connecting posts 9 are provided on the front of each housing 1 and on the front of the first and second positioning posts 7 and 8. Positioning blind holes 10 are provided on the back of each housing 1. The two housings 1 are stacked and secured together by interlocking the connecting posts 9 with the positioning blind holes 10. Furthermore, a protective cover 20 connected to the connecting posts 9 is provided on the front of the housing 1 located at the front end.

[0031] In this embodiment, a limit column 6 is fixed in the shell 1, and the limit column 6 is located on the side of the trigger switch 4 close to the first deformation part 32; when the second deformation part 34 elastically pushes the trigger switch 4 to rotate clockwise, the limit column 6 is used to limit the trigger switch 4.

[0032] In this embodiment, four pins 231 are provided on the foot seat 23 . The four pins 231 pass through the bottom of the housing 1 . The pins 231 are fixed to the circuit board, thereby fixing the housing 1 .

[0033] It should be understood that all the above embodiments are illustrative rather than restrictive. Any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the concept of the present invention are still within the scope of the technical solution of the present invention.
