[0002] Terminal blocks are accessories used to achieve electrical connections, and are classified as connectors in industry. Traditional terminal blocks are fixed with screws, which requires tools and is inconvenient for wiring. To facilitate quick wire connection, quick-connect terminals are available on the market that use elastic clips to quickly connect wires. Quick-connect terminals connect to the equipment itself with wires. However, existing quick-connect terminals have drawbacks such as large size or inconvenient assembly and installation. In addition, the number of wires in a typical quick-connect terminal is fixed, and it does not have the flexibility to assemble multiple rows side by side. Utility Model Content

[0003] In view of the prior art, the purpose of this utility model is to provide a structural arrangement scheme for quick-connect terminals, which can be used for quick connection of multiple rows of parallel terminals from wire to pin.

The pressure plate 4 is hinged to the insertion post 17 and swings relative to the terminal block 1.

[0024] As a further feature of the above solution, the pressure plate 4 is provided with a movable plate 42 with a slot 41 at one end inside the mounting cavity 11. The slot 41 on the movable plate 42 is engaged with the slot plate 28 on the spring piece 22.

[0025] As a further provision of the above scheme, the sealing plate 3 is provided with a socket 18 that matches the plug 17, and the terminal block 1 is provided with a connection hole 19 coaxial with the plug 17 on the side facing away from the plug 17. Multiple terminal blocks 1 are installed side by side with the plug 17 through the connection hole 19. The connection hole 19 allows two terminal blocks 1 to be quickly connected. The mounting cavity 11 can be sealed at the outermost terminal block 1 by a sealing plate 3. In this embodiment, the wiring terminal is installed by inserting the pin clamping spring 2 into the mounting cavity 11, then inserting the pressure plate 4, and engaging the slot 41 with the plate 28. Then, the sealing plate 3 or the second terminal block 1 is connected through the plug 17 and the socket 18 or the connection hole 19, so that they can be quickly installed side by side.

[0026] As a further provision of the above solution, the pressure plate 4 is provided with a tool groove 45 and a beveled surface 46. The beveled surface 46 is used to provide clearance space when the pressure plate 4 is pressed, so that the pressure plate 4 can swing downward until it fits against the upper surface of the terminal block 1. The angle of the tool groove 45 matches the swing of the pressure plate 4. When a tool such as a flathead screwdriver is inserted, the pressure plate 4 will swing along the hinge along the insertion post 17.

[0027] As a further feature of the above solution, the conductive base plate 23 is provided with an anti-loosening tooth 29 at one end facing the spring plate part 22. The anti-loosening tooth 29 and the spring plate part 22 cooperate to clamp the metal end of the external cable, so that the cable can be stably electrically conducted and fixed in the wire groove 12.

[0028] As a further feature of the above solution, the wire groove 12 has an opening on the terminal block 1, the wire groove 12 is provided with a guide step 15, and a clamping space 14 is provided between the spring piece 22 and the conductive base piece 23 opposite to the wire groove 12.

[0029] refer to Figure 1 and Figure 2 The quick-connect terminal structure shown in this embodiment includes a terminal block 1. The terminal block 1 has a mounting cavity 11, a wire groove 12, and a pin hole 13. A pin-holding spring 2 is provided within the mounting cavity 11. The pin-holding spring 2 in this embodiment includes a conductive base 23 and a wire-pressing spring composed of a spring portion 22 and an arc-shaped retaining portion 21. The conductive base 23 has a pin 24, such as... Figure 3 and Figure 4 As shown, in this embodiment, the conductive base plate 23 is tilted relative to the mounting cavity 11 during installation. The pin 24 is inserted into the pin hole 13 and then corrected and snapped into the mounting cavity 11. Subsequently, the wire clamping spring is snapped in from the front to achieve complete installation of the pin clamping spring 2. After installation, the conductive base plate 23 and the wire clamping spring are electrically connected. After the external cable is inserted, the spring part 22 swings to open the clamping space 14. After the front end of the cable is inserted, the spring part 22 obliquely presses and holds the cable, which not only achieves electrical conduction but also prevents it from coming out.

[0030] In this embodiment, the terminal block 1 is also provided with a plug 17 and a sealing plate 3 that engages with the plug 17. The sealing plate 3 and the terminal block 1 are also clamped together with a pressure plate 4 that abuts against the plug wire clamping spring 2. The lower end of the pressure plate 4 extends into the mounting cavity 11 and is hinged to the plug 17 for hinged swinging. The upper end extends out of the movable groove 16 and is exposed outside the terminal block 1. Under the pressure of external force, the pressure plate 4 swings, causing the spring part 22 to swing downward to release the clamping space 14. After the external cable is inserted, it is released, allowing the spring part 22 and the wire wrapping piece 25 to clamp the external cable.

[0031] Furthermore, in this embodiment, the portion of the pressure plate 4 located in the mounting cavity 11 with a slot 41 is configured as a movable plate 42. The slot 41 on the movable plate 42 engages with the slot 28 on the spring piece 22. The engaging slot 28 and slot 41 are linked together when the pressure plate 4 drives the spring piece 22 to swing up and down.

[0032] Furthermore, the sealing plate 3 is provided with a socket 18 that matches the plug 17, and the terminal block 1 is provided with a connecting hole 19 coaxial with the plug 17 on the side facing away from the plug 17.
