[0023] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-6 The present invention provides a technical solution: a protective terminal block, including a terminal block protective box 1. The terminal block protective box 1 can be detachably installed on the operating table in the production workshop. The interior of the terminal block protective box 1 is hollow. Four sets of second fixing holes 5 are arranged longitudinally around one side of the outer end of the terminal block protective box 1. Four sets of first fixing holes 4 are arranged laterally around one side of the outer end of the terminal block protective box 1. The second fixing holes 5 play a role in longitudinal fixing, and the first fixing holes 4 play a role in lateral fixing.

[0025] A fixing block 10 is fixedly installed at one end of the inside of the terminal block protection box 1, which serves to fix it horizontally. A fixing buckle 11 is fixedly installed at the other end of the inside of the terminal block protection box 1, which serves to fix it vertically.

[0026] The terminal block protective box 1 can also be detachably installed with a terminal block 3. One end of the terminal block 3 is inserted into the fixing buckle 11, and the other end is locked on the fixing block 10.

[0027] A protective cover 2 can be detachably installed on the terminal block protection box 1. An observation window 6 is fixedly installed on the protective cover 2. The observation window 6 is made of transparent acrylic material, which makes it easy for staff to observe the wiring status. Protective blocks 9 are fixedly installed on both sides of the protective cover 2 to prevent liquids or foreign objects from entering the terminal block protection box 1. Four sets of third fixing holes 7 are provided around one end of the protective cover 2.

[0028] Each of the four sets of third fixing holes 7 is equipped with a mounting rod 8, and the mounting rod 8 is provided with a mounting hole.

[0029] Example 1:

[0030] When the staff needs to use the terminal block 3 for wiring operations, the staff first fixes the terminal block protective box 1 on the operating table in the production workshop, then holds the terminal block 3 and inserts one end of the terminal block 3 into the fixing buckle 11. The fixing buckle 11 fits against the top surface of one end of the terminal block 3 and fixes it vertically. Then the staff will fix the other end of the terminal block 3 on the fixing block 10. At this time, the staff can use the terminal block 3 for wiring operations.

[0031] After the wiring is completed, the staff first holds the protective cover 2 and removes the mounting rods 8 around the protective cover 2. Then, the staff places the protective cover 2 in the terminal protection box 1 and inserts the two sets of mounting rods 8 diagonally into the second fixing holes 5 on the terminal protection box 1. Then, the staff inserts the other two sets of mounting rods 8 horizontally along the first fixing holes 4. At this time, the second set of mounting rods 8 is inserted into the mounting holes on the first set of mounting rods 8 along the first fixing holes 4, and the protective cover 2 is locked and fixed on the terminal protection box 1. At this time, the staff can perform other operations.

[0032] After the terminal block 3 is used, the staff can remove the protective cover 2 by pulling out the mounting rod 8 one by one. Then, the wires on the terminal block 3 are removed. After the removal is completed, the staff inserts the mounting rod 8 into the third fixing hole 7 around the protective cover 2 one by one. Then, the staff holds the protective cover 2 and inserts the mounting rod 8 into the second fixing hole 5 on the terminal block protective box 1.

[0033] By using the terminal protection box 1, the terminal 3 and the protective cover 2 together, the terminal 3 can be protected during use to prevent foreign objects from entering or liquids from splashing onto the terminal 3 and causing short circuits or open circuits. The mounting rod 8, the first fixing hole 4 and the second fixing hole 5 together can achieve quick disassembly and assembly. At the same time, it can fix the protective cover 2 longitudinally and laterally, improve the stability of the installation, make the operation convenient and quick, eliminate the need for nuts for installation, increase service life and prevent corrosion.
