Slide the fixing plate along the inner side of the fixing frame, so that the connection spring inside the installation box uses its own elastic force to pop out the limit block and engage with the limit groove, so that the position of the terminal block body can be quickly fixed.

[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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The technical solution shown is to solve the problem that the position of the wiring terminal itself is inconvenient to fix: the wiring terminal for the power distribution cabinet with a snap-fit ​​structure discloses a snap-fit ​​mechanism, both ends of the bottom end of the wiring terminal body 1 are fixedly connected to the limiting hole 2, the internal thread of the limiting hole 2 is connected with a bolt 3, and the middle position inside the wiring terminal body 1 is fixedly connected with a connecting hole 4;

[0031] Both sides of the terminal body 1 are fixedly connected with a fixing plate 6, and a clamping mechanism is provided on the outer side of the fixing plate 6, which is used to fix the position of the fixing plate 6 and the terminal body 1, so as to facilitate the fixing of the position of the terminal body 1 and the fixing plate 6;

[0032] Both ends of the connecting hole 4 are provided with a wire insertion opening 12, and the inner side of the wire insertion opening 12 is fixedly connected with a dust-proof and anti-slip mechanism, which is used to prevent dust from entering the wire insertion opening 12 when not in use and to prevent the wire from slipping after insertion. The dust-proof and anti-slip mechanism includes a dust-proof mechanism and an anti-slip mechanism, the dust-proof mechanism is used to reduce the entry of dust into the wire insertion opening 12, and the anti-slip mechanism is used to increase the friction between the wire and the wire insertion opening 12, thereby avoiding the positional deviation of the wire when it is not fixed.

[0033] The locking mechanism includes a fixing frame 5, and the fixing frame 5 is sleeved on the outside of the fixing plate 6, both ends of the top of the fixing frame 5 are fixedly connected with the installation box 7, and the inside of the installation box 7 is fixedly connected with the movable plate 9 through the connecting spring 8, the bottom end of the movable plate 9 is fixedly connected with the limiting block 10, and both ends of the top of the fixing plate 6 are provided with limiting grooves 11 matching the limiting block 10.

[0034] The bottom end of the limiting block 10 passes through and extends to the outside of the installation box 7, and the lower end of the outer side of the limiting block 10 is in an arc shape.

[0035] The movable plate 9 is slidably connected to the installation box 7 , and the movable plate 9 is symmetrical about the central axis of the fixing frame 5 in the vertical direction.

[0036] The connecting spring 8 is connected to the movable plate 9 , and the connecting spring 8 and the mounting box 7 are welded into an integrated structure.

[0037] In this example, the fixing frame 5 is connected to the distribution cabinet. When the wire connection is required, the wire is inserted into the wire insertion port 12, and the wire is fixed in position by rotating the bolt 3. After fixation, the fixing plate 6 is slid along the inner side of the fixing frame 5, so that the connection spring 8 inside the installation box 7 uses its own elastic force to pop out the limit block 10 and engage with the limit groove 11, so that the position of the terminal body 1 can be quickly fixed. At the same time, the installed multiple fixing frames 5 can also be used to wire the wires and the terminal body 1 to prevent the wires from falling and affecting subsequent detection.

[0038] Embodiment 2:

[0039] like Figure 1-Figure 5 The technical solution shown is to solve the problem of dust entering the wire insertion port 12 when it is not in use: the wiring terminal for a distribution cabinet with a snap-fit ​​structure discloses a dustproof mechanism, which includes an airbag 13, and the airbag 13 is fixedly connected to one end inside the wire insertion port 12, and the airbag 13 is symmetrical about the central axis of the wiring terminal body 1 in the vertical direction.

[0040] In this example, when not in use, the air bag 13 inside the wire insertion port 12 can cover the wire insertion port 12, thereby effectively reducing the entry of dust. At the same time, multiple anti-slip strips 14 can be used to cover the gaps that are not completely covered by the air bag 13, thereby better reducing the entry of dust and increasing the dust-proof performance during use.

[0041] Embodiment three:

[0042] like Figure 1-Figure 4 The technical solution shown is to solve the problem that there will be a certain gap between the wire and the wire insertion port 12 after insertion, and the position will be offset when the bolt 3 is not fixed firmly enough: the wiring terminal for the distribution cabinet with a snap-fit ​​structure discloses an anti-slip mechanism, which includes an anti-slip strip 14, and the anti-slip strip 14 is fixedly connected to the inside of the airbag 13, and a vertical first support block 15 is fixedly connected to the inside of the anti-slip strip 14, and second support blocks 16 are fixedly connected to both sides of the first support block 15.

[0043] In this example, after the wire is inserted into the wire insertion port 12, the airbag 13 is squeezed and deformed to a certain extent, so that it can adapt to the diameters of different wires, making it easier to wrap the outside of the wire. While wrapping, the anti-slip strip 14 can increase the friction between the wire and the airbag 13, and the first support block 15 and the second support block 16 can increase the support for the anti-slip strip 14 to prevent the anti-slip strip 14 from deforming and causing damage when it is performing an anti-slip effect on the wire, thereby effectively protecting the wire from slipping and preventing the wire from positional displacement when being fixed.
