Description

Technical Field

[0001] The utility model relates to the technical field of plugs, and particularly to a leakage protection plug with a protection component. Background Art

[0002] The working principle of a leakage protection plug is based on detecting the "residual current" in the "ground wire" loop. It passes the two power supply wires (live wire and neutral wire) of the plug through the central hole of a special "zero-sequence current transformer" at the same time. When this voltage signal is large enough, it will be amplified and processed by the integrated circuit on the special circuit board, and then trigger the thyristor on the board to change from cut-off to conduction, so that the trip coil connected in series in this loop is energized, and then the main circuit tripping device is disconnected, achieving the purpose of protecting personal safety;

[0003] Leakage protection plugs are widely used in the household and industrial fields. After searching the prior art for "leakage protection plugs", the publication number is "CN213753232U". This device can effectively protect the personal safety of users. However, in the industrial field, the metal tongues in the plug are exposed outside when not connected. Employees may step on or squeeze the plug during work, resulting in the bending of the metal tongues, which will affect the service life of the plug.

[0004] Therefore, a leakage protection plug with a protection component is proposed to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a leakage protection plug with a protection component to solve the above problems, improving the problem that employees may step on or squeeze the plug during work, resulting in the bending of the metal tongues, which will affect the service life of the plug.

[0006] The utility model realizes the above purpose through the following technical solutions. A leakage protection plug with a protection component includes: a connecting wire, one end of the connecting wire is fixedly connected with a leakage protector, and the end of the leakage protector away from the connecting wire is connected with an electric wire; a protection mechanism, the protection mechanism is installed at the end of the connecting wire away from the leakage protector; wherein, the protection mechanism includes a positioning component connected to the end of the connecting wire away from the leakage protector, and a protection component is arranged below the positioning component; the positioning component includes a connecting head fixedly connected to the end of the connecting wire away from the leakage protector, and a plurality of metal tongues are fixedly connected to the lower end of the connecting head, and the plurality of metal tongues are distributed in a ring along the edge of the connecting head.

[0007] Preferably, the protection component includes a protective sleeve sleeved on the surface of the connector head. An outer positioning ring is fixedly connected to the inner wall of the protective sleeve. A plurality of plastic elastic pieces are fixedly connected to the inner bottom wall of the protective sleeve. The plastic elastic pieces are annularly distributed along the inner wall of the protective sleeve. A plurality of through holes are formed in the lower end of the protective sleeve. The through holes are staggeredly distributed with the adjacent metal tongues. When an external force is applied, the metal tongues will not directly contact the ground, avoiding the situation that the metal tongues are bent due to being stepped on, and ensuring the lasting normal use effect of the metal tongues.

[0008] Preferably, an inner positioning ring is fixedly connected to the lower end of the surface of the connector head. A plurality of limiting grooves are formed in the surface of the inner positioning ring. The limiting grooves are evenly distributed annularly. The cooperation of the outer positioning ring and the inner positioning ring avoids the situation that the device is easily separated.

[0009] Preferably, a plurality of limiting strips are fixedly connected to the lower end of the outer positioning ring. The limiting strips are fixedly connected to the inner bottom wall of the protective sleeve.

[0010] Preferably, the limiting strips are located inside the adjacent limiting grooves. One side of the limiting strip is slidably connected to the inner wall of the adjacent metal tongue. The rotation amplitude of the limiting strip in the limiting groove is consistent with the angle of the metal tongue resetting and aligning with the through hole.

[0011] Preferably, a cleaning layer is fixedly connected to the inner bottom wall of the protective sleeve. The through holes penetrate to the upper end of the cleaning layer. The metal tongue will contact the surface of the cleaning layer when passing through the through hole.

[0012] Preferably, a plurality of plastic pressing pieces are arranged on the surface of the cleaning layer. The end of the plastic pressing piece far away from the cleaning layer is fixedly connected to the inner bottom wall of the protective sleeve. The plastic pressing pieces form a good positioning effect on the cleaning layer.

[0013] The beneficial effects of the present utility model are as follows: 1. The above-mentioned leakage protection plug with a protection component can protect the metal tongue under the action of the protection mechanism. Through the setting of the protective sleeve, when being stepped on by an external force, the situation that the metal tongue is bent under pressure can be reduced, and the contamination of the metal tongue by external impurities can also be reduced through the setting, and at the same time, the metal tongue can be assisted in cleaning, extending the service life of the device.

[0014] 2. By setting the protection component, under the action of the protection component, the protective sleeve can play a good protection effect. And because the metal tongue and the through hole are staggeredly arranged in the long term, the situation that the metal tongue is bent due to being stepped on can be avoided, ensuring the lasting normal use effect of the metal tongue.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] During specific implementation: As Figures 1-5 shown, a leakage protection plug with a protection component includes: a connecting wire 1, one end of the connecting wire 1 is fixedly connected with a leakage protector 2, and a wire is connected to the end of the leakage protector 2 away from the connecting wire 1; a protection mechanism 3, and the protection mechanism 3 is installed at the end of the connecting wire 1 away from the leakage protector 2; wherein, the protection mechanism 3 includes a positioning component 31 connected to the end of the connecting wire 1 away from the leakage protector 2, and a protection component 32 is arranged below the positioning component 31;

[0023] As Figures 1-5As shown, the protection component 32 includes a protective sleeve 321 sleeved on the surface of the connector 311. An outer positioning ring 322 is fixedly connected to the inner wall of the protective sleeve 321. A plurality of plastic elastic pieces 324 are fixedly connected to the inner bottom wall of the protective sleeve 321. The plastic elastic pieces 324 are annularly distributed along the inner wall of the protective sleeve 321. A plurality of through holes 327 are formed in the lower end of the protective sleeve 321. The through holes 327 are misaligned with the adjacent metal tongues 314. A plurality of limiting strips 323 are fixedly connected to the lower end of the outer positioning ring 322. The limiting strips 323 are fixedly connected to the inner bottom wall of the protective sleeve 321. The limiting strips 323 are located inside the adjacent limiting grooves 313. One side of the limiting strip 323 is slidably connected to the inner wall of the adjacent metal tongue 314. A cleaning layer 326 is fixedly connected to the inner bottom wall of the protective sleeve 321. The through holes 327 penetrate to the upper end of the cleaning layer 326. A plurality of plastic pressing pieces 325 are arranged on the surface of the cleaning layer 326. The end of the plastic pressing piece 325 away from the cleaning layer 326 is fixedly connected to the inner bottom wall of the protective sleeve 321;

[0024] Among them, the plurality of plastic elastic pieces 324 are arranged in a spiral shape. The protective sleeve 321 can form a protective effect on the lower end of the positioning component 31. And when the plastic elastic pieces 324 are arranged in a spiral shape, the metal tongue 314 will not be aligned with the through hole 327. When subjected to external force, the metal tongue 314 will not directly contact the ground, avoiding the situation that the metal tongue 314 is bent due to being stepped on, and ensuring the lasting normal use effect of the metal tongue 314; during the use of the device, the protective sleeve 321 can be manually rotated. At this time, when the protective sleeve 321 is rotated, the limiting strip 323 is driven to rotate inside the limiting groove 313. At this time, the plurality of plastic elastic pieces 324 are twisted. Furthermore, the limiting strip 323 fits to the other end of the inner wall of the limiting groove 313. And at the same time, the through hole 327 is aligned with the lower end of the metal tongue 314. At this time, the positioning component 31 can be pressed on the socket for connection. And the cleaning layer 326 can assist in cleaning the surface of the metal tongue 314. At the same time, the plastic pressing piece 325 ensures the positioning effect on the cleaning layer 326;

[0025] Such as Figure 2 、 Figure 3 and Figure 4As shown in the figure, the positioning component 31 includes a connector 311 fixedly connected to the end of the connecting wire 1 away from the leakage protector 2. A plurality of metal tongues 314 are fixedly connected to the lower end of the connector 311. The plurality of metal tongues 314 are annularly distributed along the edge of the connector 311. An inner positioning ring 312 is fixedly connected to the lower end surface of the connector 311. A plurality of limiting grooves 313 are formed on the surface of the inner positioning ring 312. The limiting grooves 313 are evenly distributed in a ring shape. When the device is in use, the operator can press the connector 311 to align the metal tongues 314 with the jacks on the socket. At this time, the limiting grooves 313 limit the limiting strips 323, and the cooperation between the outer positioning ring 322 and the inner positioning ring 312 prevents the device from being easily detached.

[0026] When the utility model is in use, during the use process of the device, by manually rotating the protective sleeve 321 of the knob, when the protective sleeve 321 rotates the knob, it drives the limiting strip 323 to rotate inside the limiting groove 313, and a plurality of plastic elastic pieces 324 are twisted. At the same time, the plastic pressing piece 325 ensures the positioning effect on the cleaning layer 326. The cooperation between the outer positioning ring 322 and the inner positioning ring 312 prevents the device from being easily detached. Furthermore, the limiting strip 323 fits to the other end of the inner wall of the limiting groove 313, and at the same time, the through hole 327 is aligned with the lower end of the metal tongue 314. The positioning component 31 is pressed and connected to the socket, and the cleaning layer 326 provided assists in cleaning the surface of the metal tongue 314.
