[0002] There are many electromechanical equipment in coal mines, and most of them are explosion-proof equipment used in high-gas mines. Due to the long length of underground tunnels, the lines of electrical equipment will be long, often reaching several thousand meters, and the length of the cable is generally about one hundred meters. If it is too long, the cable reel will be relatively large and heavy, so there is a high risk in the process of transporting cables underground. Therefore, when the underground cable laying length is long, a junction box is used to connect the two cables to achieve long-distance cable laying.

[0003] At present, the existing technology mostly uses flameproof or explosion-proof junction boxes underground. There are three terminals inside the junction box, which are used to press the ends of two cables together to achieve the effect of conductivity.

In order to avoid the situation of personnel mistakenly sending electricity and other extremely high safety hazards during the wire pressing process, it is necessary to connect the ground wire to the terminal before safe wiring operations can be performed. However, after connecting the ground wire to the terminal, the operator needs to pay attention to the details of the wire pressing operation at all times to ensure the stable connection between the ground wire and the terminal, which increases the difficulty of the operator's wire pressing operation.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 5 As shown, an embodiment of the utility model provides a terminal block 10, including an insulating seat 11, a conductive metal tube 12, an adjusting rod 13, a fixing rod 14 and a terminal 15, wherein the conductive metal tube 12 is inserted into the insulating seat 11 and has an adjusting blind hole, the adjusting rod 13 is slidably inserted into the adjusting blind hole, one end of the adjusting rod 13 is inserted into the adjusting blind hole and elastically connected to the bottom wall of the adjusting blind hole, the other end of the adjusting rod 13 is located outside the adjusting blind hole, the adjusting rod 13 has a long hole groove 131 radially penetrating the adjusting rod 13, the long hole groove 131 is used to pass the grounding wire, the adjusting rod 13 has a normal state and a pulled-out state, when the adjusting rod 13 is in the normal state The long hole slot 131 of the adjusting rod 13 is located in the adjusting blind hole. When the adjusting rod 13 is in the pulled-out state, the long hole slot 131 partially extends out of the adjusting blind hole. The fixing rod 14 is arranged in the adjusting blind hole and one end is fixedly connected to the bottom wall of the adjusting blind hole. The other end of the fixing rod 14 penetrates into the long hole slot 131 of the adjusting rod 13. The end of the fixing rod 14 penetrated into the adjusting rod 13 cooperates with the side wall stopper of the long hole slot 131 away from the adjusting blind hole, so as to clamp the grounding wire penetrated in the long hole slot 131 and make the grounding wire abut against the end of the conductive metal tube 12. One end of the terminal 15 penetrates into the insulating seat 11 and is connected to the conductive metal tube 12.

[0030] In this embodiment, the grounding wire is no longer directly installed on the terminal post 15 but is indirectly connected to the terminal holder 10 through the conductive metal tube 12, thereby avoiding the situation in the prior art that when the grounding wire is installed on the terminal post 15, it will affect the pressing operation of the cable head also installed on the terminal post 15. Specifically, when installing the grounding wire on the terminal block 10 provided in this embodiment, the operator continuously pulls the adjusting rod 13 to convert it from the normal state to the unplugged state. When the adjusting rod 13 is in the unplugged state, the long hole slot 131 partially extends out of the insulating seat. At this time, the operator inserts the grounding wire into the long hole slot 131 or passes through the long hole slot 131. Then the operator releases the adjusting rod 13. Under the action of elasticity, the adjusting rod 13 will drive the grounding wire in the long hole slot 131 to retreat into the adjusting blind hole until the grounding wire in the long hole slot 131 is clamped between the side wall of the long hole slot 131 and one end of the fixing rod 14, and the part of the grounding wire outside the insulating seat 11 is pressed against the end of the conductive metal tube 12 due to the reset movement of the adjusting rod 13, thereby completing the installation of the grounding wire. This arrangement is conducive to the rapid installation of the grounding wire and can eliminate the influence of the grounding wire on the cable wire end crimping operation, reducing the difficulty of the operator's crimping operation. At the same time, the grounding effect is ensured by the connection of the grounding wire, the adjusting rod 13, the conductive metal tube 12 and the terminal 15. Once the wrong point is sent, the current will flow to the earth through the terminal 15, the conductive metal tube 12, the adjusting rod 13 and the grounding wire, thereby ensuring the safety of the wiring personnel.

[0031] One end of the adjusting rod 13 outside the adjusting blind hole is a handle end 133 , so that an operator can insert and remove the adjusting rod 13 easily.

[0032] like Figures 2 to 4 As shown, the adjustment rod 13 also has an opening slot 132, which is arranged between the two openings of the long hole slot 131 and communicates with the two openings of the long hole slot 131. In this way, when the adjustment rod 13 is in the pulled-out state, the long hole slot 131 partially extends out of the insulating seat, and the opening slot 132 partially or completely extends out of the insulating seat. At this time, the operator can horizontally insert a section of the vertically extending grounding wire from the opening slot 132 into the long hole slot 131, which is conducive to the rapid installation of the grounding wire and improves the convenience of installation. Preferably, the two openings of the long hole slot 131 are respectively facing upward and downward, and the part of the grounding wire used to connect to the wiring seat extends vertically during installation with the end facing downward.

[0033] Specifically, the terminal block 10 further includes an elastic member 16 disposed in the blind hole, the elastic member 16 is sleeved on the outer periphery of the fixing rod 14 and the two ends of the elastic member 16 are respectively fixedly connected to the adjusting rod 13 and the bottom wall of the blind hole. This arrangement facilitates the reset drive of the adjusting rod and ensures the clamping effect and clamping stability of the grounding wire located in the long hole groove 131.

[0034] Furthermore, the fixing rod 14 includes a rod body 141 and a pressure block 142 arranged at one end of the rod body 141, the radial dimension of the pressure block 142 is larger than the radial dimension of the rod body 141, the other end of the rod body 141 is fixedly connected to the center of the bottom wall of the adjusting blind hole, and the pressure block 142 cooperates with the side wall stop of the long hole groove 131 away from the bottom wall of the adjusting blind hole.

[0035] In this embodiment, the pressing block 142 is a rectangular block, and the cross-sectional shape of the long hole slot 131 is an adaptive rectangle. The pressing block 142 is guided and matched with the long hole slot 131. Such a setting can prevent the adjustment rod 13 and the fixed rod 14 from rotating relative to each other, and ensure the reliability and stability of the clamping of the ground wire in the long hole slot 131. At the same time, the pressing block 142 can limit the insertion and extraction of the adjustment rod 13, and prevent the adjustment rod 13 from being separated from the fixed rod 14 and / or the adjustment rod 13 from being disengaged from the adjustment blind hole, thereby ensuring the reliability and stability of the terminal block 10.

[0036] like Figure 5 As shown, the pressing block 142 has a plurality of slots 1421 on the side facing away from the rod body 141, and the slots 1421 are used to accommodate part of the copper wire of the grounding wire. In this way, when the pressing block 142 is pressed on the grounding wire, part of the copper wire of the grounding wire will be located in the slots 1421, and when the grounding wire is subjected to an upward force, the slots 1421 can also provide a certain resistance to the grounding wire, so that the grounding wire can be stably clamped in the long hole slot 131.

[0037] like Figure 1 and Figure 2 As shown, the terminal block 10 also includes a first pressure plate 171 and a second pressure plate 172, and the terminal 15 passes through the first pressure plate 171 and the second pressure plate 172. The first pressure plate 171 is arranged on the top of the insulating base 11, and the second pressure plate 172 is movably arranged above the first pressure plate 171 to be used for pressing the cable end between the two.

[0038] In this embodiment, the first pressing plate 171 and the second pressing plate 172 are used to press the cable ends. Specifically, when wiring, the cable ends of the same item of two cables are placed on the first pressing plate 171 (generally, the cable ends of the same color are pressed together), and then the second pressing plate 172 is adjusted to make the second pressing plate descend, so as to press the cable ends between the first pressing plate 171 and the second pressing plate 172. Since the present embodiment transfers the grounding wire installed on the terminal 15 in the prior art to the long hole groove 131, the operator does not need to consider the influence and limitation of the grounding wire when adjusting the second pressing plate 172 for the pressing operation, which improves the convenience of the operator in wiring.

[0039] In the utility model, the ground wire is not installed on the terminal, which allows personnel to conveniently use a wrench to tighten the cable head, and the ground wire is installed in the long hole, which is convenient and simple to install;

[0040] Specifically, the terminal post 15 has an external thread, and the terminal seat 10 further includes an adjusting nut 173, which is sleeved on the terminal post 15 and threadedly connected to the terminal post 15 to tighten or loosen the second pressing plate 172 and the first pressing plate 171. In this way, the operator only needs to use a wrench to adjust the nut, and then press down the second pressing plate 172, further improving the convenience of the operator's press-fitting operation on the cable head.

[0041] The insulating seat 11 has a mounting blind hole, and the conductive metal tube 12 is inserted into the mounting blind hole. In this embodiment, the axes of the mounting blind hole and the adjustment blind hole coincide and the openings are located on the same vertical plane, so as to ensure that the part of the grounding wire outside the insulating seat 11 can be pressed against the end of the conductive metal tube 12.

[0042] like Figure 6 and Figure 7 As shown, another embodiment of the utility model provides a junction box 20, which includes a box body 21 and the above-mentioned terminal block 10, and the terminal block 10 is detachably arranged at the bottom of the box body 21. This arrangement is convenient for disassembling and assembling the terminal block 10 according to actual conditions, which is conducive to avoiding the situation where the terminal block 15 cannot press the cable wire head when the wire is broken, and there are safety hazards, and it is convenient for the rapid replacement and maintenance of the terminal block 10. Among them, there are multiple terminal blocks 10, and multiple terminal blocks 10 are all threadedly installed at the bottom of the box body 21 through screws 22. This arrangement is conducive to the rapid disassembly and assembly of the terminal block 10 and the number of terminal blocks 15 located inside the junction box 20 according to actual conditions. Among them, three terminal blocks 10 are arranged in the junction box 20 in this embodiment, and any terminal block 10 contains two parallel terminal blocks 15. It can be understood that the structure for disassembling and assembling the terminal block 10 is not limited to the screw 22, and other structures that can achieve rapid disassembly and assembly are all possible, and no examples are given here one by one.
