[0003] However, current terminal block structures are simple, and the wiring channels are usually exposed, lacking a sealing structure. This allows external dust, weeds, moisture, etc., to enter the contact channels and come into contact with the internal metal conductive plates and screws, causing problems. For example, dust contact can lead to arc discharge, and dust can increase resistance. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a terminal block with a self-sealing structure, which can completely seal the terminal block body through a sealing plate, a clamping plate and a baffle, so as to prevent external impurities from entering the interior, thereby solving the problems mentioned in the background art.

[0005] This utility model is achieved through the following technical solution: a terminal block with a self-sealing structure, including a terminal block body, with clamping plates installed on both sides of the terminal block body, and each clamping plate having a lower arc-shaped groove at the connection channel of the terminal block body. A central rod is horizontally installed in the middle of the terminal block body, and sealing plates are installed on both sides of the central rod through hinges. The end of the sealing plate away from the central rod is bent downward to form a clamping part, and the clamping part is fitted to the clamping plate. Each clamping part has an upper arc-shaped groove at the lower arc-shaped groove, and the upper and lower arc-shaped grooves are combined to form a clamping channel. Baffles that seal the clamping channel are provided on the outer side of the clamping part and the clamping plate.

[0006] As a preferred technical solution, the baffle is provided with multiple positioning holes vertically, and a fixing rod is installed on the outer side of the clamping part. The positioning holes are provided with positioning rods, one end of which extends to the outside and is installed on the fixing rod. The other end of the positioning rod is set higher than the upper arc groove. A compression spring is sleeved on the positioning rod. One end of the compression spring is installed on the baffle, and the other end is installed on the fixing rod. The inner side of the baffle is in contact with the outer side of the clamping part and the clamping plate.

[0007] As a preferred technical solution, the inner surface of the sealing plate protrudes to form a sealing part at the wiring channel of the terminal body, and the sealing part is inserted into the wiring channel.

[0008] As a preferred technical solution, all hinge components are torsion spring hinges.

[0009] As a preferred technical solution, both ends of the center rod are equipped with screws, and each screw is threaded with a nut to press the sealing plate tightly.

[0010] As a preferred technical solution, the sealing plate, clamping part, baffle and clamping plate are all made of insulating plastic material.

[0011] As a preferred technical solution, the positioning rods are all made of metal.

[0012] The beneficial effects of this utility model are as follows: This utility model has a simple structure, and the wire can be connected to the terminal body along the clamping channel. After the sealing plate is pressed down, the clamping plate can seal the wiring channel on the terminal body, preventing the entry of external dust, impurities, moisture and other contaminants. It can also clamp the wire, increasing the stability of the wire after installation and preventing it from affecting the safety of the terminal body. When not in use, the lowered baffle can block the outside of the clamping channel, preventing external contaminants from entering the wiring channel and increasing the safety during storage.

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0021] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a terminal block with a self-sealing structure, including a terminal block body 1. Clamping plates 2 are installed on both sides of the terminal block body 1. Each clamping plate 2 has a lower arc-shaped groove 11 directly opposite the wiring channel of the terminal block body 1. A central rod 3 is horizontally installed in the middle of the terminal block body 1. Sealing plates 4 are installed on both sides of the central rod 3 via hinges. The end of each sealing plate 4 away from the central rod 3 is bent downwards to form a clamping part 5. The clamping parts 5 are fitted against the clamping plates 2. Each clamping part 5 has an upper arc-shaped groove 12 directly opposite the lower arc-shaped groove 11. The upper arc-shaped groove 12 and the lower arc-shaped groove 11 combine to form a clamping channel. A baffle 6 is provided on the outer side of both the clamping parts 5 and the clamping plates 2 to seal the clamping channel.

[0023] In this embodiment, the baffle 6 is provided with a plurality of positioning holes 14 vertically, and a fixing rod 8 is installed on the outer side of the clamping part 5. A positioning rod 13 is provided in each positioning hole 14. One end of the positioning rod 13 extends to the outside and is installed on the fixing rod 8. The other end of the positioning rod 13 is set higher than the upper arc groove 12. A compression spring 7 is sleeved on each positioning rod 13. One end of the compression spring 7 is installed on the baffle 6 and the other end is installed on the fixing rod 8. The inner side of the baffle 6 is in contact with the outer side of the clamping part 5 and the clamping plate 2.

[0024] In this embodiment, the inner side of the sealing plate 4 protrudes to form a sealing part 15 opposite to the wiring channel of the terminal body 1. The sealing part 15 is inserted into the wiring channel. The sealing part can better seal the wiring channel and also position the sealing plate laterally, avoiding lateral displacement.

[0025] In this embodiment, the hinges are all torsion spring hinges, which can automatically lift the sealing plate by torsion of the torsion spring hinges.

[0026] In this embodiment, both ends of the central rod 3 are equipped with screws 9, and each screw 9 is threaded with a nut 10 that presses the sealing plate 4 together.

[0027] In this embodiment, the sealing plate 4, the clamping part 5, the baffle 6, and the clamping plate 2 are all made of insulating plastic material, which avoids short circuits caused by electrical conductivity and increases safety during use.

[0028] In this embodiment, the positioning rods 13 are all made of metal, which increases the robustness and ensures the stability of the baffle.

[0029] When in use, remove the nut from the screw. After the nut's clamping force is released, the sealing plate can automatically lift up through the torsion of the torsion spring hinge, directly exposing the wiring channel. The wire core on the wire can be directly fixed to the screw in the wiring channel, and the outer protective layer of the wire can be placed into the lower arc groove. After pressing down the sealing plate, the clamping part on the sealing plate can abut against the clamping plate, and the outer protective layer on the wire can be held and fixed through the upper and lower arc grooves, thereby increasing the stability of the wire after installation. The sealing part on the sealing plate can enter the wiring channel, increasing the lateral positioning effect.

[0030] After the above is completed, the baffle will be blocked by the wire, so that the baffle is in an upward state. After the nut is rotated and fixed on the screw, it is pressed and fixed by the sealing plate under the nut.

[0031] When not in use, once the wire is removed, the spring-loaded mechanism pushes the baffle downwards, blocking the outside of the clamping channel and preventing external contaminants from entering the wiring channel. This increases storage time and safety during subsequent use.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
