[0033] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] Example:

[0035] like Figures 1 to 5 As shown, this embodiment discloses a simple plug-in terminal block structure, including an insulating housing 10 and a wiring assembly 11 disposed in the insulating housing 10, wherein the wiring assembly 11 is detachably connected to the insulating housing 10;

[0036] The wiring assembly 11 includes a conductive sheet body 12 and a pair of wiring spring structures 13. The conductive sheet body 12 has mounting structures 14 for mounting the wiring spring structures 13 at both ends. The pair of wiring spring structures 13 are respectively mounted on the mounting structures 14 at both ends of the conductive sheet body 12 and are detachably connected to the mounting structures 14.

[0037] The wiring spring structure 13 includes a first spring 15 and a second spring 16. The mounting structure 14 includes a first limiting plate 17, a second limiting plate 18, and a limiting protrusion 19. The first limiting plate 17 is fixedly disposed at one end of the conductive sheet body 12. The second limiting plate 18 is fixedly disposed on the conductive sheet body 12 and located on one side of the first limiting plate 17. A first mounting position 20 is provided between the first limiting plate 17 and the second limiting plate 18. The first spring 15 is disposed in the first mounting position 20 and its two ends are elastically in contact with the first limiting plate 17 and the second limiting plate 18, respectively. The limiting protrusion 19 is fixedly disposed on the conductive sheet body 12 and located on the other side of the second limiting plate 18. A second mounting position 21 is provided between the limiting protrusion 19 and the second limiting plate 18. The second spring 16 is disposed in the second mounting position 21 and its two ends are elastically in contact with the second limiting plate 18 and the limiting protrusion 19, respectively.

[0038] This invention features a detachable wiring assembly 11 within an insulating housing 10. The wiring assembly 11 is based on a conductive sheet body 12, with mounting structures 14 at both ends of the conductive sheet body 12 for mounting a pair of wire spring structures 13. Each mounting structure 14 consists of a first limiting plate 17, a second limiting plate 18, and a limiting protrusion 19. A first mounting position 20 is located between the first and second limiting plates 17 and 18, and a second mounting position 21 is located between the second limiting plate 18 and the limiting protrusion 19 for mounting the first spring 15 and the second spring 16 of the wire spring structures 13. The elastic contact points between the first spring 15 and the first limiting plate 17, and between the second spring 16 and the second limiting plate 18, allow for the elastic fixing of the wires. The pair of wire spring structures 13 and the mounting structures 14 at both ends of the conductive sheet body 12 are arranged in a mirror-symmetrical manner on the conductive sheet body 12.

[0039] When installing wires, the wires are inserted directly into the spring clips to deform them. The spring clips' elastic restoring force is used to clamp and fix the wires. When removing wires, the wires can be pulled out directly without a screwdriver. This solves the problem that current direct-insertion terminal blocks require screwdrivers for disassembly and assembly, which is complicated and time-consuming.

[0040] To facilitate the installation of the first spring piece 15 and the second spring piece 16, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the upper end of one side of the first limiting plate 17 is provided with a first limiting rib 22 that cooperates with one end of the first spring piece 15. One end of the first spring piece 15 contacts the first limiting rib 22, and the first limiting rib 22 is used to restrict the upward freedom of the first spring piece 15. The upper end of one side of the first limiting plate 17 is provided with a first limiting strip 23 that cooperates with one side of the first spring piece 15. One end of the first limiting strip 23 extends toward the first mounting position 20, and one side slides in contact with one side of the first spring piece 15. The first limiting strip 23 is used to prevent the first spring piece 15 from shifting or misaligning when it is not wired.

[0041] The second limiting plate 18 has a second limiting rib 24 on one side upper end that cooperates with one end of the second spring piece 16. One end of the second spring piece 16 contacts the second limiting rib 24, and the second limiting rib 24 is used to restrict the upward freedom of the second spring piece 16. The second limiting plate 18 has a second limiting strip 25 on one side upper end that cooperates with one side of the second spring piece 16. The second limiting strip 25 extends toward the second mounting position 21 and slides in contact with one side of the second spring piece 16. The second limiting strip 25 is used to prevent the second spring piece 16 from shifting or misaligning when it is not wired. The second limiting plate 18 has a third limiting strip 26 on one side lower end that cooperates with the other side of the first spring piece 15. The third limiting strip 26 extends toward the first mounting position 20 and slides in contact with one side of the first spring piece 15. The third limiting strip 26 is used to further prevent the first spring piece 15 from shifting or misaligning when it is not wired.

[0042] The first limiting rib 22 restricts the upward displacement of the first spring piece 15, and the first limiting strip 23 prevents it from shifting when it is not connected; the second limiting rib 24 restricts the upward displacement of the second spring piece 16, and the second limiting strip 25 prevents it from being misaligned when it is not connected; the third limiting strip 26 further assists in fixing the position of the first spring piece 15.

[0043] In use, these structures can effectively constrain the degrees of freedom of the first spring 15 and the second spring 16, preventing the first spring 15 and the second spring 16 from becoming loose or misaligned due to vibration or being unconnected, ensuring that the first spring 15 and the second spring 16 can accurately contact the wires when wiring, thus improving the stability and reliability of the wiring.

[0044] To facilitate the installation of the wiring assembly 11, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the insulating housing 10 is provided with a first mounting groove 27, a connecting mounting groove 28 and a second mounting groove 29 on one side. The connecting mounting groove 28 is located between the first mounting groove 27 and the second mounting groove 29 and is used to connect the first mounting groove 27 and the second mounting groove 29. A pair of wiring spring structures 13 are respectively installed in the first mounting groove 27 and the second mounting groove 29. The conductive sheet body 12 is installed in the connecting mounting groove 28. The two ends of the conductive sheet body 12 with mounting structures 14 are respectively installed in the first mounting groove 27 and the second mounting groove 29.

[0045] The first mounting slot 27 and the second mounting slot 29 respectively accommodate the wire spring structures 13 at both ends of the conductive sheet body 12. The connecting mounting slot 28 is used to place the conductive sheet body 12 and connects the first mounting slot 27 and the second mounting slot 29, so that the conductive sheet body 12 and the wire spring structures 13 at both ends form a complete conductive path.

[0046] In use, the installation slots allow for the partitioned installation of each component in the wiring assembly 11, optimizing the spatial layout and making the overall structure more compact. They also provide precise installation positioning for the wiring assembly 11, facilitating its overall disassembly, assembly, and maintenance.

[0047] To further facilitate the installation of the first spring 15 and the second spring 16, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a first limiting structure 30 is fixedly provided in the first mounting groove 27. The first limiting structure 30 is located above one end of the conductive sheet body 12 and is used to limit the mounting structure 14 and the wiring spring structure 13 located in the first mounting groove 27. A second limiting structure 31 is fixedly provided in the second mounting groove 29. The second limiting structure 31 is located above the other end of the conductive sheet body 12 and is used to limit the mounting structure 14 and the wiring spring structure 13 located in the second mounting groove 29.

[0048] The first limiting structure 30 and the second limiting structure 31 each include a first limiting block 32, a first limiting post 33, a first limiting protrusion 34, a second limiting block 35, a second limiting post 36, and a second limiting protrusion 37 arranged sequentially. A first slot 38 is provided between the first limiting block 32 in the first limiting structure 30 and the side wall of the first mounting groove 27. A second slot 39 is provided between the first limiting block 32 in the second limiting structure 31 and the side wall of the second mounting groove 29. First limiting plates 17 at both ends of the conductive sheet body 12 are respectively inserted into the first slot 38 and the second slot 39, and a first limiting strip 23 is located above the first limiting block 32. A first limiting groove 40 is provided at the upper end of the first limiting block 32, which cooperates with one end of the first spring piece 15. The first limiting groove 40 is used to prevent the first spring piece 15 from shifting or misaligning during wiring. One end is inserted between the first limiting post 33 and the first limiting protrusion 34. The first limiting protrusion 34 is used to prevent the first spring piece 15 from interfering with the second limiting plate 18 during installation. The second limiting plates 18 at both ends of the conductive sheet body 12 are respectively inserted between the first limiting protrusion 34 and the second limiting block 35, and the second limiting strip 25 is located above the second limiting block 35, and the third limiting strip 26 is located below the first limiting protrusion 34. The upper end of the second limiting block 35 is provided with a second limiting groove 41 that cooperates with one end of the second spring piece 16. The second limiting groove 41 is used to prevent the second spring piece 16 from shifting or misaligning during wiring. The other end of the second spring piece 16 is inserted between the second limiting post 36 and the second limiting protrusion 37. The second limiting protrusion 37 is used to prevent the second spring piece 16 from interfering with the limiting protrusion 19 during installation. The limiting protrusion 19 is located below the second limiting protrusion 37.

[0049] By setting the first limiting block 32, the first limiting post 33, the first limiting protrusion 34, the second limiting block 35, the second limiting post 36, and the second limiting protrusion 37, the first mounting groove 27 and the second mounting groove 29 respectively form the first slot 38, the second slot 39, and a number of limiting spaces that are adapted to the conductive sheet body 12, the first spring 15, and the second spring 16. During installation, the first slot 38 and the second slot 39 can facilitate the corresponding insertion of the first limiting plates 17 at both ends of the conductive sheet body 12. The first limiting groove 40 and the second limiting groove 41 respectively constrain the displacement space when the first spring 15 and the second spring 16 are wired, avoiding misalignment when the first spring 15 and the second spring 16 are wired. The first limiting protrusion 34 and the second limiting protrusion 37 can effectively prevent interference between the first spring 15 and the second limiting plate 18 during installation and interference between the second spring 16 and the limiting protrusion 19 during installation.

[0050] In use, these structures can reduce the installation gap between the components of the wiring assembly 11, further fix the position of the wiring assembly 11, prevent the components from shifting during wiring or disassembly, and improve the stability and assembly accuracy of the overall structure.

[0051] To facilitate wiring, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the insulating housing 10 has two pairs of wiring ports 42 on one side. One pair of wiring ports 42 is connected to the first mounting groove 27, and the other pair of wiring ports 42 is connected to the second mounting groove 29. One wiring port 42 corresponds to the connection between the first spring 15 and the first limiting plate 17, and the other wiring port 42 corresponds to the connection between the second spring 16 and the second limiting plate 18.

[0052] Two pairs of connectors 42 are connected to the first mounting slot 27 and the second mounting slot 29, respectively. Each pair of connectors 42 in each mounting slot is aligned with the elastic contact points of the first spring contact 15 and the first limiting plate 17, and the second spring contact 16 and the second limiting plate 18, providing a precise direct insertion channel for the wires. In use, this effectively clarifies the wire insertion position, guides the wire to quickly contact the spring contact, reduces alignment time during wiring, improves wiring efficiency, and ensures the contact accuracy between the wire and the spring contact.

[0053] To facilitate the installation and removal of auxiliary wires, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the insulating housing 10 has two pairs of sliding slots 43 on one side. One pair of sliding slots 43 communicates with the first mounting slot 27, and the other pair of sliding slots 43 communicates with the second mounting slot 29. One sliding slot 43 is corresponding to the middle of the first spring piece 15, and the other sliding slot 43 is corresponding to the middle of the second spring piece 16. The sliding slots 43 are located on the side of the wiring port 42. Each sliding slot 43 is provided with a push block 44. The push block 44 is inserted into the sliding slot 43 and is slidably connected to the sliding slot 43. The end of the push block 44 can contact the middle of the first spring piece 15 or the second spring piece 16.

[0054] The sliding slot 43 is connected to the mounting slot. The push block 44 slides along the sliding slot 43, and its end can contact the middle of the spring piece. When disassembling the wire, push the push block 44 to squeeze the spring piece to deform it, release the clamping force on the wire, and make it easier to pull out the wire.

[0055] When in use, it provides an auxiliary disassembly function for tightly clamped wires, avoiding damage to the spring contacts or wire breakage caused by forcibly pulling out the wires, further simplifying the disassembly operation and improving ease of use.

[0056] To facilitate the stable sliding of the push block 44, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a limiting groove 45 is provided on one side of the push block 44, and a limiting block 46 is fixedly provided on one side of the sliding groove 43 to cooperate with the limiting groove 45. The limiting block 46 is located in the limiting groove 45 and is slidably connected to the limiting groove 45.

[0057] The limiting block 46 is embedded in the limiting groove 45 of the push block 44 and can slide relative to it, providing guidance for the movement of the push block 44 and preventing the push block 44 from shifting laterally or falling off during the sliding process. In use, it can effectively ensure the accuracy of the movement trajectory of the push block 44, avoid the push block 44 from getting stuck or shifting during operation, ensure the stable implementation of the auxiliary disassembly function, and improve the user experience.

[0058] To facilitate stable sliding of the push block 44 within its working range, this embodiment is an improvement upon the previous embodiment. The difference lies in that a limiting protrusion 50 is provided at one end of the push block 44, located at the bottom of the limiting groove 45. A first limiting part 47, which cooperates with the limiting protrusion 50, is provided in the sliding groove 43.

[0060] Working principle of this utility model:

[0061] This invention features a detachable wiring assembly 11 within an insulating housing 10. The wiring assembly 11 is based on a conductive sheet body 12, with mounting structures 14 at both ends of the conductive sheet body 12 for mounting a pair of wire spring structures 13. Each mounting structure 14 consists of a first limiting plate 17, a second limiting plate 18, and a limiting protrusion 19. A first mounting position 20 is provided between the first and second limiting plates 17 and 18, and a second mounting position 21 is provided between the second limiting plate 18 and the limiting protrusion 19 for mounting the first spring 15 and the second spring 16 of the wire spring structure 13. The elastic contact points between the first spring 15 and the first limiting plate 17, and between the second spring 16 and the second limiting plate 18, allow for the elasticity of the springs to secure the wires. When installing the wire, the wire is inserted directly into the spring, causing it to deform. The elastic restoring force of the springs provides clamping and fixation. When removing the wire, it can be pulled out directly without a screwdriver.
