Technical Field
[0001] The utility model belongs to the technical field of electrical equipment production, and in particular relates to a power cord plug with an anti-line-off structure. Background Art
[0002] The power cord plug refers to the device that connects electrical appliances and other devices to the power supply. The power sockets and plugs vary in appearance, grade, size and type according to different countries and regions;
[0003] At present, most common power cord plugs on the market are two-pin or three-pin plugs. When these plugs are plugged into sockets, they are fixed by clamping the socket contact copper sheet 5 set inside the socket. However, during long-term use, due to the occurrence of metal fatigue, the clamping force of the socket contact copper sheet 5 decreases, resulting in the power cord plug being easily loose when inserted, and then very easy to fall off.
[0004] Therefore, in view of the above problems, the utility model provides a power cord plug with an anti-line-off structure to meet the needs. Utility Model Content

[0007] As a preferred power cord plug with an anti-wire-off structure of the utility model, the power plug comprises: a plug body, a power cord and an anti-sliding block, the power cord is connected to one end of the plug body, and the anti-sliding block is connected to both sides of the plug body.
[0008] In order to facilitate the compressed retraction of the spring piece, as a preferred power cord plug with an anti-line-off structure of the utility model, the retraction hole is a table tennis racket-shaped through hole with a central circle and a rectangular end connected to it, the spring piece has the same shape as the retraction hole, and the size of the spring piece is smaller than the size of the retraction hole.
[0009] In order to achieve good conductivity of the power plug, as a preferred embodiment of the power plug with an anti-line-off structure of the utility model, the spring piece and the plug pin are both made of metal copper.
[0010] In order to further improve the anti-dropping effect of the power plug, as a preferred embodiment of the power plug with an anti-dropping structure of the utility model, the anti-slip pad is made of rubber material.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] The utility model provides anti-dropping components on both sides of the plug pin, so that when the power plug is fully inserted into the socket, the anti-slip pad can be well pressed and fitted with the inner wall of the socket panel through the elasticity of the spring piece and the cooperation of the anti-slip pad to form a connection state similar to interference fit, so that the power plug is not easy to drop off, thereby realizing the anti-dropping function.

[0020] 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.
[0021] See also Figure 1-5 The utility model provides the following technical solutions: a power cord plug with an anti-line-off structure, comprising a power plug 1, the power plug 1 comprising: a plug body 101, a power cord 102 and an anti-slip block 103, the power cord 102 is connected to one end of the plug body 101, the anti-slip block 103 is connected to both sides of the plug body 101, the anti-slip block 103 is in the shape of a semicircular strip and is arranged at equal intervals on both sides of the plug body 101, so as to increase the anti-slip effect between the hand and the plug body 101, thereby facilitating the plugging and unplugging of the power plug 1, two opposite pins 7 are connected to the end of the power plug 1, and the inside of the pins 7 are provided with an anti-slip component, the anti-slip component comprises: a retraction hole 2, a spring sheet 3 and an anti-slip pad 4, the retraction hole 2 is opened inside the pin 7, the spring sheet 3 is connected to the inner wall of the retraction hole 2, the anti-slip pad 4 is adhered to the surface of the spring sheet 3, and the anti-slip pad 4 is a hemispherical body.
[0022] Preferably: the retraction hole 2 is a table tennis racket-shaped through hole with a circular center and a rectangular end. The spring piece 3 has the same shape as the retraction hole 2, and the size of the spring piece 3 is slightly smaller than the size of the retraction hole 2, ensuring that the spring piece 3 and the anti-slip pad 4 can be completely retracted into the retraction hole 2.
[0023] During specific use, after the power plug 1 is inserted into the socket, the deformation of the spring piece 3 can make the anti-slip pad 4 fit tightly against the inner wall of the socket hole of the socket panel 6, thereby increasing the friction between the pin 7 and the socket panel 6, making it difficult for the power plug 1 to fall off.
[0024] Preferably, the spring piece 3 and the pin 7 are both made of metal copper, and the anti-slip pad 4 is made of rubber.
[0025] When used specifically, copper material has good conductivity and ductility, while rubber material is not only an insulator, but also has a very rough surface with many tiny bumps and pits. These particles can contact another surface, making the "pressure" generated between the two surfaces greater, thereby generating greater friction, and then cooperating with the elasticity of the spring piece 3 to further achieve anti-slippage.
[0026] It should be specially noted here that the anti-dropping component in the technical solution of the present application can also be used for a three-pin plug. Compared with the two-pin plug of the present application, it is only necessary to set the anti-dropping component on all three pins 7.
[0027] Working principle: When the power cord plug with an anti-offline structure is in use, the pin 7 of the power plug 1 is inserted into the socket. At the same time, the socket contact copper sheet 5 in the socket clamps the pin 7, and the elasticity of the spring sheet 3 makes the anti-slip pad 4 fit closely to the inner wall of the socket hole of the socket panel 6, forming a connection structure similar to an interference fit, further strengthening the friction between the pin 7 and the inner wall of the socket panel 6, thereby effectively preventing the power plug 1 from falling off.
[0028] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
