[0001] The utility model relates to the technical field of leakage protectors, and particularly relates to a leakage protection protector. Background Art

[0002] A leakage protector, abbreviated as a leakage switch and also called a leakage circuit breaker, is mainly used to protect against leakage faults of equipment and fatal electric shock to the human body, and has overload and short-circuit protection functions. An electric meter is an instrument for measuring electric energy, and a row-connected electric meter refers to electric meters connected together. Due to the importance of the electric meter, a leakage protector needs to be installed inside the electric meter to ensure the safety of electricity use.

[0003] In the prior art, when connecting wires to a leakage protector, it is necessary to first strip off a section of the insulating outer skin of the wire to expose the copper core inside, then install the copper core into the wiring port of the leakage protector, and then tighten the bolt of the wiring port to fix the copper core. Since the wire near the wiring port has its insulating layer stripped off, the copper core is directly exposed to the air, posing a safety hazard. Moreover, the current leakage protector is not simple and convenient to disassemble and assemble. Therefore, it is necessary to design a leakage protection protector to solve the above problems.

[0004] The information disclosed in this background art section is only intended to enhance the understanding of the overall background of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0032] See Figure 1 、Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present utility model provides a leakage protection protector, comprising:

[0035] The positioning plug 3 is clamped with the leakage protector main body 1, the fitting block 6 is clamped with the protective shell 5. A plurality of wire passing holes are formed on the protective shell 5. The elastic airbag 8 is fixedly installed in the wire passing holes. The air pipe 9 is fixedly installed on the elastic airbag 8. It should be noted that the elastic airbag 8 has high elasticity. When the piston rod 11 is moved into the air pipe 9, by squeezing the air, the elastic airbag 8 can be immediately inflated;

[0036] The piston rod 11 is fixedly installed at the bottom of the leakage protector main body 1. The piston rod 11 is in sliding and sealing contact with the air pipe 9. The side surface of the insertion block 12 is fixedly connected with the protective shell 5. The insertion block 12 is clamped with the mounting bracket 2 and the positioning plug 3.

[0037] Through the above-mentioned assembly protection mechanism, push the positioning plug 3 to make the positioning plug 3 snap into the leakage protector main body 1. Wire connection is carried out at the wiring terminal of the leakage protector main body 1. After the wiring is completed, pass the wire through the elastic airbag 8 and push the protective shell 5 upward. During this process, the piston rod 11 will move into the air pipe 9. As the air pipe 9 moves upward, the piston rod 11 will introduce the air in the air pipe 9 into the elastic airbag 8, causing the elastic airbag 8 to expand. The expanded elastic airbag 8 will squeeze and seal the internal wire, so that the copper core can be prevented from being directly exposed to the air, improving the protection effect. At this time, the insertion block 12 will be inserted into the insertion groove to limit the positioning plug 3. Finally, rotate the fixing screw 13 to quickly assemble the leakage protector main body 1 and also achieve a good protection effect.

[0038] Specifically, a connecting rod 10 is fixedly arranged on the air pipe 9. The connecting rod 10 is fixedly connected with the inner wall of the bottom of the protective shell 5. It should be noted that the air pipe 9 is supported and limited.

[0039] Specifically, a fixing screw rod 13 is threadedly connected to the insertion block 12, and the fixing screw rod 13 is threadedly connected to the fitting block 6. It should be noted that by screwing the fixing screw rod 13 into the fitting block 6, vertical limit of the protective case 5 is achieved.

[0040] Specifically, the main body 1 of the leakage protector is snap-fitted with the mounting frame 2. A horizontal hole is formed in the side of the mounting frame 2. The positioning plug 3 is slidably mounted in the horizontal hole. A positioning slot 4 is formed in the side of the main body 1 of the leakage protector. The positioning plug 3 is snap-fitted with the positioning slot 4. It should be noted that by inserting the positioning plug 3 into the positioning slot 4, limit of the main body 1 of the leakage protector is achieved.

[0041] Specifically, the top of the protective case 5 is in contact with the main body 1 of the leakage protector. A fitting groove 7 is formed in the top of the protective case 5. The fitting block 6 is snap-fitted with the fitting groove 7. It should be noted that by inserting the fitting block 6 into the fitting groove 7, lateral limit treatment of the protective case 5 is performed.

[0042] Specifically, an insertion hole is formed in the mounting frame 2. An insertion groove is formed in the bottom of the positioning plug 3. The insertion block 12 is snap-fitted with the insertion hole and the insertion groove. It should be noted that by inserting the insertion block 12 into the insertion hole and the insertion groove, limit treatment of the positioning plug 3 is performed.

[0043] Specifically, an assembly block 14 is fixedly arranged at the top of the mounting frame 2. The positioning plug 3 is of a T-shaped structure. The side of the insertion block 12 is in contact with the main body 1 of the leakage protector. The positioning plug 3 is in contact with the side of the mounting frame 2. It should be noted that the assembly block 14 is fixed at a specified position in advance by bolts. The positioning plug 3 is of a T-shaped structure, which facilitates manipulation treatment of the positioning plug 3.

[0044] Working principle:

[0045] S1: Refer to Figure 1 and Figure 2 and Figure 4 , place the main body 1 of the leakage protector on the mounting frame 2, push the positioning plug 3 so that the positioning plug 3 is inserted into the main body 1 of the leakage protector, and wire connection is performed at the terminal of the main body 1 of the leakage protector;

[0046] S2: Refer to Figure 5 , after wire connection is completed, pass the wire through the elastic airbag 8, then align the fitting groove 7 on the protective case 5 with the fitting block 6, and push the protective case 5 upward so that the fitting block 6 is inserted into the fitting groove 7. During this process, the piston rod 11 will move into the air pipe 9. As the air pipe 9 moves upward, the piston rod 11 will introduce the air in the air pipe 9 into the elastic airbag 8, causing the elastic airbag 8 to expand. The expanded elastic airbag 8 will squeeze and seal the internal wire, so that the copper core can be prevented from being directly exposed to the air, improving the protection effect;

[0047] S3: Refer to Figure 4 and Figure 5 , at this time, the insertion block 12 will be inserted into the insertion groove to limit the positioning insert block 3. Finally, rotate the fixing screw 13 to quickly assemble the main body 1 of the leakage protector, which is relatively convenient for disassembly and assembly, and at the same time, a good protection effect can be achieved.
