[0035] It should be noted that the protection piece 2 is mainly made of insulating material and covers the metal exposed part to play a protection role; wherein, with reference to Figure 2The rotating part 21 of the protection part 2 is used for rotating the whole protection part 2, the first connecting part 22 of the protection part 2 is used for being inserted into the groove of the bolt, the connecting body 33 is used for connecting the rotating part 21 and the first connecting part 22, the second connecting part 3 is arranged at the part of the connecting body 33 close to the rotating part 21, the second connecting part 3 comprises a disc body 31 arranged on the connecting body 33 and a clamping block 32 arranged on the disc body 31, the disc body 31 is matched with the end part of the positioning part 1 provided with the second limiting part 12, and the working principle of the clamping block 32 is the same as that of the ratchet strip, so that the clamping block 32 is matched with the clamping space 13 of the end part of the positioning part 1.

[0036] With reference to Figure 4 And Figure 5 Further, the terminal strip body 4, and the connecting port 41 arranged at the end part of the terminal strip body 4, at least one group of protrusions 42 are arranged on the inner wall of the connecting port 41, and the protrusions 42 are provided with at least three prisms, for example, the protrusions 42 are rectangular, and it should be noted that the terminal strip in the utility model can be processed in equal proportions according to the model of the terminal strip, so that the terminal strip in the utility model can adapt to various use scenarios.

[0037] With reference to Figure 1 And Figure 3 When the terminal strip is used, firstly, the terminal strip body 4 is fixed on the required disc cabinet or equipment guide rail, the wiring is correctly connected and fastened by using the fastening screw, then the end part of the positioning part 1 away from the second limiting part 12 is pressed into the connecting port 41 of the terminal strip end part, when the positioning part 1 enters the connecting port 41 of the terminal strip, the first limiting part 11 of the side wall of the positioning part 1 is aligned with the protrusion 42 in the connecting port 41, after the positioning part 1 is completely pushed into the connecting port 41, the clamping block 32 of the second connecting part 3 is aligned with the clamping space 13 of the second limiting part 12 of the end part of the positioning part 1, then the protection part 2 is fastened by pressing down in the direction of the fastening screw, at this time, the first connecting part 22 of the protection part 2 may not fall into the groove of the end part of the fastening screw, the rotating part 21 of the protection part 2 needs to be pressed and the rotating part 21 needs to be twisted clockwise, if the protection part 2 falls a certain distance, it is indicated that the first connecting part 22 of the protection part 2 falls into the groove of the end part of the fastening screw, and the function of fixing the fastening screw is realized. Since the thickness of the second limiting part 12 of the end part of the positioning part 1 is much thicker than that of the clamping block of the protection part 2, the second limiting part 12 can support a certain length of the protection part 2;

[0038] With reference to Figure 5 And Figure 6 Since the second limiting part 12 in the embodiment is ratchet-shaped, when the clamping block 32 is clamped between the ratchet-shaped second limiting part 12, the locking cylinder and the protection part 2 can be locked.

[0040] The rest of the structure is the same as the previous embodiment.

[0041] Referring to Figure 7 , as an optional embodiment, one side of the second limiting portion 12 is connected with the edge of the end of the positioning piece 1, and the second limiting portion 12 is provided with a first side 121 and a second side 122 connected with the first side 121 away from the end of the positioning piece 1, the first side 121 is a right angle side, and the second side 122 is a circular arc side, and the second limiting portion 12 is movably connected with the end of the positioning piece 1.

[0042] It should be noted that the second limiting portion 12 in the embodiment is as shown in Figure 7 , one end of the positioning piece 1 provided with the second limiting portion 12 is provided with a containing groove matched with the second limiting portion 12, so that the second limiting portion 12 can move back and forth along the containing groove, and a return spring is arranged between the second limiting portion 12 and the containing groove, because the first side 121 of the second limiting portion 12 is a right angle side and the second side 122 is a circular arc side, so that the second connecting portion 3 can only rotate in one direction along the second limiting portion 12.

[0043] The rest of the structure is the same as the previous embodiment.

[0044] Referring to Figure 8 and Figure 10 , as an optional embodiment, the terminal row body 4; and the connecting port 41 provided at the end of the terminal row body 4, at least one group of protrusions 42 is arranged on the inner wall of the connecting port 41, and the protrusions 42 at least include one circular arc edge.

[0045] Referring to Figure 8 to Figure 11 , it should be noted that the protrusions 42 are rectangular in the first embodiment, and relative to the first embodiment, as Figure 8 , Figure 10The difference of the embodiment is that the protrusion 42 can be Ω-shaped, circular, rhombic (the adjacent sides of the rhombic are connected through the circular arc side), etc., and the shape of the first limiting part 11 of the positioning member 1 also changes accordingly. The difference between the role of the protrusion 42 in the embodiment and the first embodiment is that, by adopting the above shape, the protrusion 42 in the connecting port 41 of the terminal strip is connected through the wedge structure, and at the same time, the shape itself has the locking effect on the positioning member 1, so that the positioning member 1 cannot easily fall off from the connecting port 41 of the terminal strip, thereby making the use scene of the terminal strip in the embodiment more extensive.

[0046] The rest of the structure is the same as the last embodiment.

[0047] Finally, it should be pointed out that the above detailed description of the method and device is only an embodiment, and those skilled in the art can modify the embodiment in different ways without departing from the scope of the present application.
