[0002] At present, in the power supply field, the terminal block is an important electrical component with high usage rate, which can be applied to the measurement secondary circuit and its role is irreplaceable. The terminal block is an electrical component used to connect the circuit, and its role mainly has two points: one is to facilitate the arrangement of the circuit, and a mark can be made beside each terminal post, which is more clear and beautiful in use and convenient for maintenance; the other is to control the closing and opening of the connection, which is convenient for use and operation.

[0003] In the protection inspection process, the terminal block needs to be re-tightened to find out the situation that individual terminal blocks are not tightened when fixing the cable, so as to avoid the risk. However, the existing terminal block is judged whether it has been tightened only by the feeling of the staff, which is very subjective, resulting in inconsistent tightening degree of different wiring terminals, and the situation that the secondary circuit is abnormal due to loose wiring, and each terminal needs to be tightened once, so the efficiency of the searching process is low. SUMMARY

The observation hole is located on one side of the compression assembly, and the cable insertion hole is located on one side of the adjusting assembly. The cable can be inserted between the adjusting assembly and the compression assembly through the cable insertion hole. The adjusting assembly can move towards the compression assembly to clamp the cable. The observation hole is used to observe the compression amount of the compression assembly after being compressed.

[0008] The connecting component includes two connecting conductors, and the conductor blocks of the two connecting conductors are connected by the connecting component.

[0009] As an alternative to the aforementioned terminal block, the compression assembly includes a first metal clamp, an identification element, and an elastic element. The two ends of the identification element are respectively connected to the first metal clamp and the elastic element. The elastic element is connected to the inner wall of the accommodating cavity. The first metal clamp is disposed opposite to the adjustment assembly. The identification element is located at the observation hole.

[0010] As an alternative to the aforementioned terminal block, the conductor block has a first light-transmitting hole, the insulating shell has a second light-transmitting hole, the first light-transmitting hole is connected to the receiving cavity, and the first light-transmitting hole and the observation hole are respectively located on both sides of the identification element; the second light-transmitting hole is connected to the first light-transmitting hole, and the identification element is a transparent element, allowing light sources to enter the transparent element through the second light-transmitting hole and the first light-transmitting hole.

[0011] As an alternative to the aforementioned terminal block, the aforementioned adjustment assembly includes a first adjusting bolt and a second metal clamp connected to the first adjusting bolt. The first adjusting bolt is threadedly connected to the aforementioned conductor block, and both ends of the first adjusting bolt pass through the aforementioned conductor block. The second metal clamp is disposed opposite to the aforementioned compression assembly.

[0012] As an alternative to the aforementioned terminal block, the aforementioned connection assembly includes a second adjusting bolt and two oppositely arranged connecting pieces. The second adjusting bolt is threadedly connected to the two connecting pieces to drive the two connecting pieces to move closer to or further away from each other. The two connecting pieces are used to clamp the two conductor blocks.

[0013] As an alternative to the aforementioned terminal block, the aforementioned insulating housing is provided with a placement groove, and the aforementioned connecting component and two aforementioned connecting conductors are disposed in the aforementioned placement groove; the side wall of the aforementioned insulating housing is also provided with a cable through hole, the aforementioned cable through hole is connected to the aforementioned placement groove, and the aforementioned cable socket and the aforementioned observation hole are both corresponding to the opening of the aforementioned cable through hole.

[0014] As an alternative to the aforementioned terminal block, the aforementioned conductor block is further provided with a test socket, one end of the aforementioned placement groove is passed through to form a clearance opening, and the aforementioned test socket, the aforementioned connection component, and the aforementioned adjustment component are all located at the aforementioned clearance opening.

[0015] As an alternative to the aforementioned terminal block, the aforementioned insulating housing is provided with two numbered slots, each corresponding to one of the two aforementioned connecting conductors, and the numbered slots are used to insert numbered components.

[0016] As an alternative to the aforementioned terminal block, the aforementioned insulating housing is further provided with a guide rail slot, which is used to insert a guide rail component.

[0019] The terminal block includes an insulating housing, connecting conductors, and connecting components, all of which are housed within the insulating housing. The connecting conductor includes a conductor block, a compression component, and an adjusting component. The adjusting component is movably connected to the conductor block, allowing it to move relative to the conductor block. The conductor block has a receiving cavity, within which the compression component and part of the adjusting component are located. The conductor block has a cable insertion hole and an observation hole on its side, both of which are connected to the receiving cavity. The observation hole is located on one side of the compression component, and the cable insertion hole is located on one side of the adjustment component. The cable can be inserted between the adjustment component and the compression component through the cable insertion hole. The adjustment component can move towards the compression component to clamp the cable, thereby connecting the cable to the conductor block. At the same time, during the process of the adjustment component squeezing the cable, the compression component will compress to the side away from the cable. The observation hole is used to observe the amount of compression after the compression component is compressed. Thus, the degree of compression on the cable can be directly obtained by observing the amount of compression of the compression component. This ensures that the cable connection is secure during wiring, avoids loose wiring that could lead to secondary circuit abnormalities, and eliminates the need to tighten multiple terminal blocks during protection maintenance, thereby improving inspection efficiency.

[0033] Embodiments of the present invention 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 the present invention, and should not be construed as limiting the present invention.

[0034] Example 1

[0035] This embodiment provides a terminal block for connecting cables to enable or disable circuit connection.

[0036] like Figures 1-6 As shown, the terminal block includes an insulating housing 1, a connecting conductor 2, and a connecting assembly 3, both of which are housed within the insulating housing 1. The connecting conductor 2 includes a conductor block 21, a compression assembly 22, and an adjustment assembly 23. The adjustment assembly 23 is movably connected to the conductor block 21, allowing it to move relative to the conductor block 21. The conductor block 21 has a receiving cavity 211, within which the compression assembly 22 and part of the adjustment assembly 23 are located.

[0037] The conductor block 21 has a cable insertion hole 212 and an observation hole 213 on its side. Both the cable insertion hole 212 and the observation hole 213 are connected to the receiving cavity 211. The observation hole 213 is located on one side of the compression component 22, and the cable insertion hole 212 is located on one side of the adjustment component 23. The cable can be inserted between the adjustment component 23 and the compression component 22 through the cable insertion hole 212. The adjustment component 23 can move towards the compression component 22 to clamp the cable, thereby connecting the cable to the conductor block 21. At the same time, during the process of the adjustment component 23 squeezing the cable, the compression component 22 will be compressed to the side away from the cable. The observation hole 213 is used to observe the amount of compression after the compression component 22 is compressed. Thus, the degree of compression of the cable can be directly obtained by observing the amount of compression of the compression component 22. This ensures that the cable connection is stable during wiring, avoids loose wiring and secondary circuit abnormalities, and eliminates the need to tighten multiple terminal blocks during protection maintenance, thereby improving inspection efficiency. Optionally, the conductor block 21 is provided with a scale mark at the observation port, so that the degree of compression of the cable can be directly observed through the scale mark.

[0038] like Figure 2 and Figure 3 As shown, the compression assembly 22 includes a first metal clamp 221, an identification element 222, and an elastic element 223. The two ends of the identification element 222 are respectively connected to the first metal clamp 221 and the elastic element 223. The elastic element 223 is connected to the inner wall of the receiving cavity 211, so that the first metal clamp 221, the identification element 222, and the elastic element 223 as a whole will not fall off the inner wall of the conductor block 21. The first metal clamp 221 is arranged opposite to the adjustment assembly 23, so that the first metal clamp 221 can make rigid contact with the cable and clamp the cable with the adjustment assembly 23. The identification element 222 is located at the observation hole 213, so that the operator can directly observe the identification element 222 through the observation hole 213, and then directly obtain the degree of compression of the cable by the amount of movement of the identification element 222.

[0039] like Figures 3-5 As shown, the conductor block 21 has a first light-transmitting hole 214, and the insulating shell 1 has a second light-transmitting hole 11. The first light-transmitting hole 214 is connected to the receiving cavity 211, and the first light-transmitting hole 214 and the observation hole 213 are respectively located on both sides of the identification element 222. The second light-transmitting hole 11 is connected to the first light-transmitting hole 214, and the identification element 222 is a transparent element. The light source can enter the transparent element through the second light-transmitting hole 11 and the first light-transmitting hole 214, causing the transparent element to emit light, thereby facilitating the judgment of the moving length of the identification element 222. Optionally, when multiple terminal blocks are stacked sequentially, the multiple first light-transmitting holes 214 and the multiple second light-transmitting holes 11 can be interconnected to form a light path channel, thereby facilitating the entry of the light source. Further optionally, a light source element and a blocking element are respectively provided at both ends of the light path channel, and the light source element can emit light.

[0040] The adjusting component 23 includes a first adjusting bolt 231 and a second metal clamp 232 connected to the first adjusting bolt 231. The first adjusting bolt 231 is threaded to the conductor block 21, and both ends of the first adjusting bolt 231 are disposed through the conductor block 21. Meanwhile, the second metal clamp 232 is disposed opposite to the compression component 22. Thus, by rotating the first adjusting bolt 231, the distance between the second metal clamp 232 and the compression component 22 can be adjusted to achieve clamping or loosening of the cable.

[0041] Furthermore, the connecting assembly 3 includes a second adjusting bolt 31 and two opposing connecting pieces 32. The second adjusting bolt 31 is threadedly connected to the two connecting pieces 32 to drive the two connecting pieces 32 to move closer or further apart. The two connecting pieces 32 are used to clamp the two conductor blocks 21, enabling the two conductor blocks 21 to be electrically connected, thereby connecting the cables on the two conductor blocks 21 and achieving circuit conduction. When the second adjusting bolt 31 drives the two connecting pieces 32 to move further apart, the electrical connection between the two conductor blocks 21 can be disconnected for ease of use and operation. Specifically, when the two ends of the connecting pieces 32 contact the two conductor blocks 21 respectively, the adjusting bolt drives the two connecting pieces 32 to move closer together, thereby clamping the two conductor blocks 21 and completing the circuit connection; when the adjusting bolt drives the two connecting pieces 32 to move further apart, the connecting pieces 32 are moved towards one of the two conductor blocks 21, allowing the connecting piece 32 to separate from the other, thereby completing the circuit disconnection.

[0042] like Figure 1 , Figure 5 and Figure 6 As shown, the insulating shell 1 is provided with a placement groove 12, and the connecting component 3 and two connecting conductors 2 are disposed in the placement groove 12. The side wall of the insulating shell 1 is also provided with a cable through hole 13, which is connected to the placement groove 12. The cable insertion hole 212 and the observation hole 213 are both corresponding to the opening of the cable through hole 13. Thus, the cable can be inserted into the cable insertion hole 212 through the cable through hole 13, and the observation hole 213 can be easily observed. The conductor block 21 is also provided with a test insertion hole 215. One end of the placement groove 12 passes through to form a clearance opening 121. The test insertion hole 215, the connecting component 3, and the adjusting component 23 are all located at the clearance opening 121. Thus, when multiple terminal blocks are stacked in sequence, the test insertion hole 215, the compression component 22, and the adjusting component 23 can be adjusted and used through the clearance opening 121, which is convenient for protection and maintenance.

[0043] Optionally, the insulating housing 1 is provided with two numbering slots 14, each corresponding to one of the two connecting conductors 2. The numbering slots 14 are used to insert numbering components to mark each connecting conductor 2 for easy maintenance. Further optionally, the insulating housing 1 is also provided with a guide rail slot 15, which is used to insert guide rail components to facilitate the sequential stacking of multiple terminal blocks.

[0044] Example 2

[0045] This embodiment also provides a terminal block assembly, including the wiring terminal block as shown in Embodiment 1, such as... Figure 7 and Figure 8 As shown, there are multiple terminal blocks, which are stacked sequentially. The terminal block group also includes an insulating cover 4, which covers the top insulating shell 1 to prevent workers from accidentally touching the connecting conductor 2 and avoid the risk of electric shock.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
