[0043] Reference Figure 1 and Figure 2 The terminal block includes a mounting body 1, an input conductive plate 2, an input component 3, an output conductive plate 4, an output component 5, and a fuse component 6.

[0044] Reference Figure 2 and Figure 3 Both the input conductive plate 2 and the output conductive plate 4 are elastically snapped into the mounting body 1, and are spaced apart along the length of the mounting body 1. The input component 3 includes an input button 31 and an input pressure plate 32. After the wire passes through the mounting body 1, pressing the input button 31 presses the wire between the input conductive plate 2 and the input pressure plate 32, thus connecting the wire to the input conductive plate 2. Similarly, the output component 5 includes an output button 51 and an output pressure plate 52. Pressing the output button 51 presses the wire between the output conductive plate 4 and the output pressure plate 52.

[0045] The fuse assembly 6 comprises a mounting shell 61, a first connecting conductive sheet 62, a second connecting conductive sheet 63 and a fuse element 64. The mounting shell 61 is mounted on the mounting body 1. The first connecting conductive sheet 62 and the second connecting conductive sheet 63 are fixed in the mounting shell 61 by elastic clamping. The first connecting conductive sheet 62 and the second connecting conductive sheet 63 are arranged along the length direction of the mounting body 1 and are spaced apart from each other. The first connecting conductive sheet 62 is connected to the input conductive sheet 2, and the second connecting conductive sheet 63 is connected to the output conductive sheet 4. The fuse element 64 is mounted in the mounting body 1. The two ends of the fuse element 64 are connected to the first connecting conductive sheet 62 and the second connecting conductive sheet 63 respectively, so as to realize the connection between the first connecting conductive sheet 62 and the second connecting conductive sheet 63. In this embodiment, the fuse element 64 is a fuse tube. The two ends of the fuse element 64 are connected to the first connecting conductive sheet 62 and the second connecting conductive sheet 63 respectively.

[0046] In actual application, one wire is connected to the input conductive sheet 2 through the input assembly 3, and the other wire is connected to the output conductive sheet 4 through the output assembly 5. Since the input conductive sheet 2 is connected to the first connecting conductive sheet 62, the output conductive sheet 4 is connected to the second connecting conductive sheet 63, and the fuse element 64 is connected to the first connecting conductive sheet 62 and the second connecting conductive sheet 63, the connection between the input conductive sheet 2 and the output conductive sheet 4 is realized, so that the two wires are electrically connected.

[0047] When the current is abnormal, the fuse element 64 is fused to disconnect the first connecting conductive sheet 62 and the second connecting conductive sheet 63, so as to disconnect the terminal, avoid equipment damage and fire, and improve the safety of the terminal.

[0048] Referring to Figure 2 and Figure 4 In some embodiments, the mounting shell 61 comprises a shell body 611 and a cover body 612. The shell body 611 is mounted on the mounting body 1. The first connecting conductive sheet 62 and the second connecting conductive sheet 63 are mounted in the shell body 611. The fuse element 64 is detachably connected to the cover body 612. The cover body 612 is detachably connected to the shell body 611. In this embodiment, a plurality of insertion posts 612a are formed on the cover body 612. A plurality of insertion grooves 611a are formed on the shell body 611. Each insertion post 612a is inserted into each insertion groove 611a, so as to realize the detachable connection between the cover body 612 and the shell body 611. The structure is simple and convenient to operate. When the fuse element 64 is damaged, the cover body 612 is detached from the shell body 611, and the fuse element 64 is detached from the cover body 612. A new fuse element 64 is replaced. Thus, the terminal can be repeatedly used, so as to reduce the use cost.

[0049] With reference to Figure 2 , Figure 3 and Figure 5 , in some embodiments, the lower side of one end of the shell 611 is rotatably connected to the upper side of the mounting body 1, the first connecting conductive sheet 62 and the second connecting conductive sheet 63 are both provided through the mounting body 1, and the first connecting conductive sheet 62 is inserted into the input conductive sheet 2 to achieve connection with the input conductive sheet 2, and the second connecting conductive sheet 63 is inserted into the output conductive sheet 4 to achieve connection with the output conductive sheet 4, thus also achieving fixation between the shell 611 and the mounting body 1 to ensure the stability of the use of the wiring terminal.

[0050] In some embodiments, the lower side of the shell 611 protrudes to form a clamping seat 611b, and the upper side of the mounting body 1 is provided with a clamping groove 11, and the clamping seat 611b is clamped in the clamping groove 11, thereby improving the stability of the fixation between the shell 611 and the mounting body 1. It should be noted that the clamping seat 611b also has an insertion slot 611a, and the cover body 612 is inserted into the clamping seat 611b, so that the lower side of the cover body 612 is limited in the clamping groove 11, and the first connecting conductive sheet 62 and the second connecting conductive sheet 63 are both limited between the clamping seat 611b and the cover body 612, which can effectively improve the stability of the installation of the first connecting conductive sheet 62 and the second connecting conductive sheet 63 on the shell 611, and at the same time, the cover body 612 can be disassembled from the shell 611 only by rotating the shell 611 to make the clamping seat 611b disengage from the clamping groove 11, the first connecting conductive sheet 62 disengage from the input conductive sheet 2, and the second connecting conductive sheet 63 disengage from the output conductive sheet 4, that is, to disconnect the electrical connection of the two wires, so as to replace the safety element 64 to prevent misoperation of the staff.

[0051] With reference to Figure 5 , in some embodiments, the shell 611 protrudes to form a rectangular limiting rib 611c at the rotating position, and the upper side of the mounting body 1 is provided with a limiting groove 12, and the shape of the limiting groove 12 matches the limiting rib 611c. By rotating the shell 611, the first connecting conductive sheet 62 disengages from the input conductive sheet 2, and the second connecting conductive sheet 63 disengages from the output conductive sheet 4, at which time the limiting rib 611c is limited in the limiting groove 12 to limit the rotation of the shell 611, so as to facilitate the installation and disassembly of the safety element 64. It should be noted that the number of limiting ribs 611c can be multiple, and the multiple limiting ribs 611c are arranged at intervals along the rotation direction of the shell 611, so as to facilitate the adjustment of the position of the rotation of the shell 611.

[0052] With reference to Figure 2 and Figure 4In some embodiments, one side of the cover 612 protrudes to form a clasp 612b and two limiting plates 612c, the safety element 64 is clamped in the clasp 612b and abuts against the two limiting plates 612c respectively, so as to realize the detachable connection between the safety element 64 and the cover 612, which is simple in structure and convenient to operate.

[0053] In some embodiments, the two ends of the safety element 64 abut against the first connecting conductive sheet 62 and the second connecting conductive sheet 63 respectively, so as to realize the stable connection between the safety element 64 and the first connecting conductive sheet 62 and the second connecting conductive sheet 63, and make the first connecting conductive sheet 62 and the second connecting conductive sheet 63 clamp the safety element 64 and the shell 611, so as to improve the stability of the installation of the first connecting conductive sheet 62 and the second connecting conductive sheet 63 on the shell 611, thereby improving the stability of the working of the wiring terminal.

[0054] In some embodiments, the mounting shell 61 further comprises a connecting plate 613, one end of the connecting plate 613 is integrally connected to the shell 611, and the other end is integrally connected to the cover 612, so as to realize the connection between the shell 611 and the cover 612, which can effectively prevent the cover 612 from being lost.

[0055] The implementation principle of the embodiment is that in actual application, one wire is connected to the input conductive sheet 2 through the input assembly 3, and the other wire is connected to the output conductive sheet 4 through the output assembly 5. Since the input conductive sheet 2 is connected to the first connecting conductive sheet 62, the output conductive sheet 4 is connected to the second connecting conductive sheet 63, and the safety element 64 is connected to the first connecting conductive sheet 62 and the second connecting conductive sheet 63, the connection between the input conductive sheet 2 and the output conductive sheet 4 is realized, so that the two wires are electrically connected.

[0056] When the current is abnormal, the safety element 64 is fused to disconnect the first connecting conductive sheet 62 and the second connecting conductive sheet 63, so as to realize the power-off of the wiring terminal, and avoid the damage of the equipment and the fire as much as possible, thereby improving the safety of the use of the wiring terminal. Of course, in other embodiments, the safety element 64 can also be a light-emitting diode, which is extinguished when the current is abnormal, so as to prompt the staff.
