[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 3 As shown, an anti-loosening terminal comprises a terminal body 1, a mounting block 4 is detachably mounted on the top of the inner wall of the terminal body 1, a connecting component 5 is arranged on one side of the mounting block 4, a first sealing plate 6 is detachably mounted on one side of the terminal body 1, and a second sealing plate 7 is detachably mounted on the corresponding side of the terminal body 1, the connecting component 5 comprises a sleeve 16, one end of the sleeve 16 is connected to one side of the mounting block 4, a connecting bolt 17 is connected to the inner thread of the sleeve 16, and a staff connects one side of the first sealing plate 6 of one terminal body 1 to the second sealing plate 6 of another terminal body 1. One side of the plate 7 is fitted, and then the positioning plate 18 detachably installed on the top of the first covering plate 6 is inserted into the limiting groove opened on the top of the second covering plate 7, and the connecting bolt 17 is rotated in the sleeve 16 through a thread into the sleeve 16 on another identical terminal body 1. One end of the connecting bolt 17 protruding from the sleeve 16 is connected with the internal thread of the sleeve 16 on another identical terminal body 1, thereby connecting and combining the two terminal bodies 1. The terminal bodies 1 can be used alone, and the staff can also freely combine them according to wiring requirements. No external combination fixing tools are required, and the equipment is more independent.

[0023] like Figure 3 and Figure 4As shown, the inner wall of the terminal body 1 is symmetrically provided with a fixing frame 2 which can be detachably installed on both sides, and an anti-detachment component 3 is arranged at the bottom of the fixing frame 2. The anti-detachment component 3 includes a copper column sheet 8, and a copper plate 9 is symmetrically detachably installed on the top of the copper column sheet 8. A storage hole is opened at the top of the copper column sheet 8, and an elastic rubber column 10 is detachably installed at the bottom of the inner wall of the storage hole opened by the copper column sheet 8, and an insulating column 11 is detachably installed on the top of the elastic rubber column 10. Slide grooves are symmetrically opened on both sides of the inner wall of the fixing frame 2, and the slide grooves opened by the fixing frame 2 are slidably connected to the limit plate 12, and an elastic rubber belt 13 is detachably installed on the top of the limit plate 12. A pressure plate 14 is detachably installed on one side of the plate 12, and a fastening bolt 15 is threadedly connected to the top of the pressure plate 14. The elastic rubber belt 13 drives the limit plate 12 to be at the top of the slide groove opened in the fixed frame 2 under the action of its own elastic force. The limit plate 12 drives the pressure plate 14, and the pressure plate 14 drives the fastening bolt 15. The top of the fastening bolt 15 is movably penetrated with the top of the terminal body 1, so that the fastening bolt 15 is at the top of the terminal body 1. There is no need to remove the fastening bolt 15. The fastening bolt 15 is driven by the pressure plate 14 away from the copper plate 9 to leave installation space. The fastening bolt 15 is not easy to lose and is also convenient for staff to operate.

[0024] When wiring is installed, the staff will put the circular hole of the circular terminal onto the protruding part of the insulating column 11 on the copper plate 9, preliminarily locate the installation position of the circular terminal, and then push and tighten the fastening bolt 15. The fastening bolt 15 pushes the pressure plate 14 to abut the circular terminal. The fastening bolt 15 is threadedly rotated on the pressure plate 14 through the circular hole of the circular terminal to abut the insulating column 11. Then the fastening bolt 15 pushes the insulating column 11 to compress the elastic rubber column 10, and the insulating column 11 retracts into the copper column sheet 8. One end of the fastening bolt 15 is threadedly connected to the top of the copper plate 9 until the fastening bolt 15 is tightened on the pressure plate 14. The fastening bolt 15 locks the pressure plate 14 and the copper plate 9, thereby locking and installing the circular terminal. The insulating column 11 preliminarily locates the installation position of the circular terminal, which is convenient for the subsequent fastening bolt 15 to position the circular hole through the circular terminal, and is convenient for the staff to install. The locking installation of the fastening bolt 15 not only crimps the circular terminal, but the circular terminal is also not easy to loosen under the limit of the fastening bolt 15, and is firmly installed.

[0025] How it works

[0026] It should be noted that the utility model is a terminal block that prevents loosening. When in use, the staff first takes the terminal body 1, and the terminal body 1 drives the mounting plate 19, and uses the mounting holes on the mounting plate 19 to install the mounting plate 19 to the specified position, thereby fixing the terminal body 1. After the installation is completed, the staff pulls the wire crimped with the round terminal and places the round terminal into the fixing frame 2. The insulating column 11 partially extends out of the copper plate 9 under the elastic force of the elastic rubber column 10, and the circular hole of the round terminal is sleeved on the protruding part of the insulating column 11 on the copper plate 9 to preliminarily locate the installation position of the round terminal. Then the staff pushes the fastening bolt 15, and the fastening bolt 15 pushes the pressure plate 14 to drive the limit plate 12 to slide in the fixing frame 2. The limit plate 12 stretches the elastic rubber band 13 until the pressure plate 14 abuts against the top of the circular terminal placed in the fixed frame 2, and then the staff tightens the fastening bolt 15, and the fastening bolt 15 rotates on the pressure plate 14 through the thread, and the fastening bolt 15 passes through the circular hole of the circular terminal and abuts the insulating column 11, and continues to tighten the fastening bolt 15, and the fastening bolt 15 pushes the insulating column 11 to compress the elastic rubber column 10, and the insulating column 11 retracts into the copper column sheet 8, and one end of the fastening bolt 15 is threadedly connected to the top of the copper plate 9 until the fastening bolt 15 is tightened on the pressure plate 14, and the fastening bolt 15 locks the pressure plate 14 and the copper plate 9, and the pressure plate 14 and the copper plate 9 press the circular terminal between the two, completing the installation, achieving the purpose of installation without removing the bolts, and facilitating the operation of the staff.

[0027] When it is necessary to combine the terminal bodies 1, two identical terminal bodies 1 are fitted together, one side of the first covering plate 6 of the terminal body 1 is fitted with one side of the second covering plate 7 of the other terminal body 1, and the positioning plate 18 detachably installed on the top of the first covering plate 6 is inserted into the limiting groove on the top of the second covering plate 7. The staff rotates the connecting bolt 17, and the connecting bolt 17 is threadedly rotated in the sleeve 16 toward the sleeve 16 on the other identical terminal body 1. One end of the connecting bolt 17 extending out of the sleeve 16 is connected to the internal thread of the sleeve 16 on the other identical terminal body 1, thereby connecting and combining the two terminal bodies 1 to achieve the purpose of conveniently combining the same terminal bodies 1.
