[0002] As disclosed in a power cord with the publication number CN214899255U, it includes a wire body and a device plug arranged at one end of the wire body. The device plug includes a plug-in part, and a plug-in hole is formed in the plug-in part. A dust cover is arranged on the device plug, and the inner side wall of the dust cover is in plug-in fit with the outer side wall of the plug-in part along the length direction of the plug-in part; several plug blocks that are in plug-in fit with the plug-in holes are arranged on the inner wall of the end of the dust cover far away from the opening. This application has the effect of reducing the water around the plug-in part and reducing the risk of electric shock to people.

[0003] The existing floor track power cords are mostly composed of wire bodies with three-wire cores wrapped by rubber materials, and are energized by directly connecting to an external power supply.

[0004] Since the outer layer of the power cord is covered with a layer of rubber insulating sleeve, it is extremely difficult to detect when the inner core leaks electricity.

[0005] In view of this, the utility model provides a floor track power cord with a leakage monitoring function to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a floor track power cord with a leakage monitoring function, aiming to solve the problem that it is extremely difficult to detect when the core of the power cord leaks electricity in the prior art.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A floor track power cord with a leakage monitoring function includes a floor track power cord main body and a digital display three-phase ammeter. The floor track power cord main body includes: three groups of cores and three groups of core insulating sleeves. The three groups of cores are respectively wrapped in the three groups of core insulating sleeves, and the three groups of cores are respectively a neutral line, a live line and a ground wire.

[0008] The digital display three-phase ammeter includes: a digital display three-phase ammeter main body, a connecting part and three groups of connecting pins. The connecting part is arranged at both ends of the digital display three-phase ammeter main body. The three groups of connecting pins are arranged inside the connecting part and are electrically connected to the digital display three-phase ammeter main body. The three groups of connecting pins are respectively a neutral line pin, a live line pin and a ground wire pin.

[0009] The three groups of cores are respectively electrically connected to the corresponding three groups of connecting pins one by one to form a current path.

[0010] Preferably, as a ground rail power cord with a leakage monitoring function of the present utility model, the ground rail power cord body further includes: a first filling layer, a shielding layer, a second filling layer, and a main body insulating sleeve. The first filling layer and the shielding layer are sequentially coated between the battery cell and the battery cell insulating sleeve. The main body insulating sleeve coats three groups of the battery cell insulating sleeves, and the second filling layer is filled between the main body insulating sleeve and the three groups of the battery cell insulating sleeves.

[0011] Preferably, as a ground rail power cord with a leakage monitoring function of the present utility model, the first filling layer and the second filling layer are made of polypropylene fillers.

[0012] Preferably, as a ground rail power cord with a leakage monitoring function of the present utility model, the shielding layer is a woven copper wire mesh.

[0013] Preferably, as a ground rail power cord with a leakage monitoring function of the present utility model, the main body insulating sleeve and the battery cell insulating sleeve are made of rubber materials.

[0014] Preferably, as a ground rail power cord with a leakage monitoring function of the present utility model, the surface of the main body insulating sleeve is integrally connected with friction blocks which are evenly distributed.

[0015] Preferably, as a ground rail power cord with a leakage monitoring function of the present utility model, the friction blocks are in a semi-cylindrical convex shape.

[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] 1. By connecting the three battery cells in the ground rail power cord body to a digital display three-phase ammeter, the current on each line can be detected by the digital display three-phase ammeter. The user can judge whether there is a leakage in each line through the change of the current value, so as to realize the real-time monitoring of the leakage of the power cord.

[0018] 2. By arranging friction blocks on the surface of the ground rail power cord body, the ground rail power cord body can have good wear resistance. When it contacts the ground or other objects, it will first rub the friction blocks instead of directly rubbing the surface of the ground rail power cord body, which not only improves the service life of the ground rail power cord body, but also effectively prevents the surface of the ground rail power cord body from being damaged, and further prevents the occurrence of leakage.

[0024] 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 making creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1 - 3 , the present utility model provides the following technical solutions: A ground rail power cord with a leakage monitoring function includes a main body 1 of the ground rail power cord and a digital display three-phase ammeter 2. The main body 1 of the ground rail power cord includes: three groups of battery cells 101 and three groups of battery cell insulating sleeves 102. The three groups of battery cells 101 are respectively coated in the three groups of battery cell insulating sleeves 102. The three groups of battery cells 101 are respectively a neutral wire, a live wire and a ground wire. The main body 1 of the ground rail power cord further includes: a first filling layer 103, a shielding layer 104, a second filling layer 105 and a main body insulating sleeve 106. The first filling layer 103 and the shielding layer 104 are sequentially coated between the battery cell 101 and the battery cell insulating sleeve 102. The shielding layer 104 is a braided copper wire mesh. The main body insulating sleeve 106 coats the three groups of battery cell insulating sleeves 102. The main body insulating sleeve 106 and the battery cell insulating sleeve 102 are made of rubber material. The second filling layer 105 is filled between the main body insulating sleeve 106 and the three groups of battery cell insulating sleeves 102. The first filling layer 103 and the second filling layer 105 are made of polypropylene filler; The digital display three-phase ammeter 2 includes: a main body 201 of the digital display three-phase ammeter, a connecting part 202 and three groups of connecting contact pins 203. The connecting part 202 is arranged at both ends of the main body 201 of the digital display three-phase ammeter. The three groups of connecting contact pins 203 are arranged inside the connecting part 202 and are electrically connected to the main body 201 of the digital display three-phase ammeter. The three groups of connecting contact pins 203 are respectively a neutral wire contact pin, a live wire contact pin and a ground wire contact pin; The three groups of battery cells 101 are respectively electrically connected to the corresponding three groups of connecting contact pins 203 one by one to form a current path;

[0026] During specific use, when the main body 1 of the ground rail power cord is connected to an external power source to form a current path, the main body 201 of the digital display three-phase ammeter 2 will display the current values of each line; when a live wire leaks electricity, the current will flow through an unexpected path, resulting in a decrease in current; when the neutral wire leaks electricity, it will cause an imbalance in the current in the circuit, that is, the current is not equal among the phases and keeps changing because part of the current flows to the ground through the leakage circuit; when the ground wire leaks electricity, it will cause a significant increase in the ground current in the circuit because the leakage current returns to the power source through the ground wire; therefore, by observing the change in the value of the digital display three-phase ammeter 2, real-time monitoring of leakage can be achieved.

[0027] Furthermore, in order to improve the friction resistance of the main body 1 of the ground rail power cord and prevent the surface of the main body 1 of the ground rail power cord from being damaged and causing leakage, semicircular convex friction blocks 3 evenly distributed can be integrally connected to the surface of the main body insulating sleeve 106 of the main body 1 of the ground rail power cord. Due to the setting of the friction blocks 3, when the main body 1 of the ground rail power cord contacts other objects, its surface will not directly contact the object for friction, but first through the friction blocks 3 for friction. Only when the friction of the friction blocks 3 disappears will it directly friction the surface of the main body 1 of the ground rail power cord. Therefore, the wear-resistant effect of the main body 1 of the ground rail power cord can be effectively improved, and the leakage caused by the friction damage of the skin of the main body 1 of the ground rail power cord can be reduced.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
