Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the embodiments of the present utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0030] In the embodiments of the present utility model, unless otherwise clearly specified and limited, terms such as "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0031] In one embodiment of the present utility model, as Figures 1 to 4As shown, a DC power cord with a dustproof function is provided, including a female plug 10, a line body 20 and a male plug 30 connected in sequence, the male plug 30 is provided with a pin 40, and also includes a dustproof member 50, the dustproof member 50 is slidably sleeved on the corresponding pin 40, the male plug 30 is provided with a accommodating cavity 31 for accommodating the dustproof member 50, the dustproof member 50 includes a plurality of dustproof parts 51, and a connecting part 52 connecting each of the dustproof parts 51, each of the dustproof parts 51 is provided with a first through hole 511, the connecting part 52 is provided with a boss 521, and the boss 521 is connected to a handle 522.

[0032] Specifically, when in use, the boss 521 is pressed to make each dustproof piece 50 slide on the pin 40 into the accommodating cavity 31, so that the pin 40 is completely exposed, and then it can be used. When not in use, the handle 522 on the boss 521 can be pried out to pull the dustproof piece 50 out of the accommodating cavity 31, so that the dustproof piece 50 can completely cover the pin 40, thereby protecting the pin 40 and preventing the pin 40 from being contaminated; there is no need to find another protective piece.

[0033] In another embodiment of the present invention, Figure 2 As shown, the male plug 30 includes a main body 32 and a cover 33, the accommodating cavity 31 is provided on the main body 32, the cover 33 is provided with a second through hole, the aperture of the second through hole is smaller than the opening of the accommodating cavity 31, and one end of the dustproof part 51 is provided with a limiting step 512. Specifically, since the aperture of the second through hole is smaller than the opening of the accommodating cavity 31, a limiting surface is formed on one side of the cover 33 facing the accommodating cavity 31, and is configured to cooperate with the limiting step 512 to prevent the dustproof part 50 from being completely pulled out.

[0034] In another embodiment of the present utility model, an elastic member is further provided in the accommodating cavity 31, and the elastic member is connected between the limiting step 512 and the cavity body of the accommodating cavity 31. Specifically, the elastic member can provide elastic force when the dustproof member 50 is pulled out, thereby reducing the force of the user pulling the handle 522 and improving the comfort of use.

[0035] In another embodiment of the utility model, the elastic member is a spring, and a limiting groove for the limiting spring is provided at the bottom of the limiting step 512 and the bottom of the accommodating cavity 31. Specifically, the cost of using a spring is low, and the provided limiting groove can improve the stability of the spring installation.

[0036] In another embodiment of the present utility model, a first sealing ring is disposed in the second through hole, and a second sealing ring is disposed at the upper end of the dust-proof portion 51. Specifically, when the dust-proof member 50 is placed in the accommodation cavity 31, the first sealing ring and the second sealing ring form a sealing structure to prevent liquid from entering the accommodation cavity 31 through the gap between the dust-proof member 50 and the cover body 33, thereby improving the safety performance of the DC power cord with dust-proof function.

[0037] In another embodiment of the present utility model, an annular groove is disposed at the upper end of each dust-proof portion 51, and the second sealing ring is disposed in the annular groove. Specifically, the provided annular groove facilitates the installation of the second sealing ring, avoids the displacement of the second sealing ring, and improves the stability of use.

[0038] In another embodiment of the present utility model, a reinforcing rib is further disposed between the connecting portion 52 and the dust-proof portion 51. Specifically, the provided reinforcing rib improves the strength between the connecting portion 52 and the dust-proof portion 51.

[0039] In another embodiment of the present utility model, the inner portion of each first through hole 511 is damping-connected to the pin 40. Specifically, through the damping connection between the first through hole 511 and the pin 40, the dust-proof portion 51 and the pin 40 can be kept in a static state under normal conditions.

[0040] In another embodiment of the present utility model, as Figure 4 shown, a first accommodation groove 331 is disposed on the cover body 33, and the shape of the first accommodation groove 331 matches the shape of the connecting portion 52. Specifically, the provided first accommodation groove 331 can be used to accommodate the connecting portion 52. When the dust-proof portion 51 is located in the accommodation cavity 31, the upper end surface of the connecting portion 52 is flush with the upper end surface of the cover body 33, and will not protrude to affect the use of the plug.

[0041] In another embodiment of the present utility model, the dust-proof member 50 is made of an insulating material. Specifically, by using an insulating material, it can prevent the pin 40 from leaking electricity during use and improve the safety of use.

[0042] In another embodiment of the present utility model, as Figures 1 to 2 shown, a second accommodation groove 523 for accommodating the handle 522 is further disposed on the connecting portion 52, and the handle 522 is rotatably connected to the boss 521. Specifically, the handle 522 is rotatably connected to the boss 521. By rotating the handle 522 into the second accommodation groove 523, the interference of the handle 522 during the use of the plug is prevented, and the stability of use is improved.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
