In addition, some electrical appliances are susceptible to electromagnetic interference while emitting electromagnetic interference, which reduces their performance. This is the electromagnetic interference and anti-interference problem of electrical products, namely the electromagnetic compatibility problem. The current plug power cord intelligently conducts current and power, and has no inhibitory effect on the interference signal appearing in the power supply part.

[0003] The utility model patent with patent publication number CN201720402919.2 discloses a power cord with an anti-interference plug, including a plug and a power cord, wherein the plug includes two connecting plugs and a plug body, wherein an inductor is arranged in the plug body, wherein two wire ends on one side of the inductor are respectively connected to the two connecting plugs in a one-to-one correspondence, and two wire ends on the other side are connected to the power cord; the power cord includes a wire core and an insulating layer sheathed around the wire core, and an anti-interference protector is also installed around the wire core power cord, and the anti-interference protector is coated with an insulating protective layer. The power cord with an anti-interference plug provided by the utility model has a simple structure, can effectively eliminate electromagnetic interference generated by household appliances, prevent affecting the normal use of other electrical appliances, and solve the problem of conducted interference.

[0004] However, in actual use, since the connecting plug of the device is directly connected to the socket, it is easy for children to accidentally touch the power cord and cause it to fall off, and it is very easy to get electric shock, so the safety performance is low. Utility Model Content

[0005] In order to overcome the above defects of the prior art, the utility model provides an anti-interference plug power cord to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-interference plug power cord, comprising a shell, one side of the shell is provided with a connecting plug, the other side of the shell is provided with a power cord, the outer side of the power cord is provided with an anti-interference protector, and the interior of the shell is provided with a movable snap-in assembly.

[0007] Preferably, the movable clamping assembly includes a sliding rod, which is arranged on the top of the shell, and a sliding groove is opened on the top surface of the shell, and the sliding groove is movably connected to the sliding rod, a connecting rod is provided at the bottom of the sliding rod, a fixing plate is provided at one end of the connecting rod, and a return spring is provided on the top of the fixing plate, and the number of the return springs is set to be several, and a sliding block is provided on the top of the return spring, and the sliding block passes through a side surface of the connecting plug, and the sliding block is movably connected to the connecting plug.

[0008] Through the above scheme, it can be seen that the sliding rod is connected to the connecting rod, and then the sliding rod slides inside the sliding groove to drive the connecting rod to move synchronously. When the connecting rod moves, the fixed plate at one end of the connecting rod will drive the reset spring at its top to move, and the reset spring will drive the slider at its top to move. The cross-sectional shape of the slider is set to be a triangle, and then the slider will gradually shrink into the inside of the connecting plug when moving forward to realize the movement of the slider. Therefore, when the connecting plug is connected to the socket, the connecting plug will be connected to the socket because of the slider, thereby strengthening the connection relationship between the connecting plug and the socket and improving the stability of the device.

[0009] Preferably, a threaded hole is provided on the outer surface of the shell, and a protective baffle is provided on the outer side of the shell, and the protective baffle is movably connected to the outer surface of the shell, and a rotating rod is provided inside the protective baffle, one end of the rotating rod is connected to a threaded rod, and one end of the threaded rod is fixedly connected to one end of the rotating rod, and a compression spring is provided on one side surface of the protective baffle, and the number of the compression springs is set to be several, one end of the compression spring is fixedly connected to the protective baffle, and the other end of the compression spring is movably connected to the outer surface of the shell, the number of the sliding rod and the sliding groove are both set to two, and the bottom of the sliding rod is fixedly connected to the top surface of one end of the connecting rod.

[0010] Through the above scheme, it can be seen that a protective baffle is arranged on the outside of the plug shell, and when an external object hits the shell, the protective baffle on the outside of the shell can absorb most of the impact force under the action of the compression spring, thereby preventing the external object from hitting the shell and causing the connecting plug to be misaligned or the electronic components inside the shell to be damaged, playing a buffering role and improving the practicality of the device.

[0011] Technical effects and advantages of the utility model:

[0012] 1. By setting a movable clamping assembly, a slide groove is opened on the outer surface of the shell, and a slide rod is connected to the connecting rod, and then the slide rod slides inside the slide groove to drive the connecting rod to move synchronously. When the connecting rod moves, the fixed plate at one end of the connecting rod will drive the reset spring at its top to move, and the reset spring will drive the slider at its top to move. The cross-sectional shape of the slider is set to be triangular, and then the slider will gradually shrink into the inside of the connecting plug when moving forward to realize the movement of the slider. Therefore, when the connecting plug is connected to the socket, the connecting plug will be clamped with the socket due to the slider, thereby strengthening the connection relationship between the connecting plug and the socket and improving the stability of the device;

[0013] 2. By setting a protective baffle, a protective baffle is set on the outside of the plug shell. When an external object hits the shell, the protective baffle on the outside of the shell can absorb most of the impact force under the action of the compression spring, thereby preventing the external object from hitting the shell and causing the connecting plug to be misaligned or the electronic components inside the shell to be damaged, playing a buffering role and improving the practicality of the device.

At this time, the slider 10 will limit the connecting plug 2, and then the connecting plug 2 will not be able to be separated from the socket. When the connecting plug 2 needs to be separated from the socket, it is only necessary to drive the connecting rod 7 to move through the sliding rod 5 to retract the slider 10 to the inside of the connecting plug 2 to separate the connecting plug 2 from the socket, thereby improving the stability and practicality of the device.

[0023] As attached Figure 1-3 As shown, a threaded hole 11 is provided on the outer surface of the shell 1, and a protective baffle 12 is provided on the outer side of the shell 1, and the protective baffle 12 is movably connected to the outer surface of the shell 1, and a rotating rod 13 is provided inside the protective baffle 12, and one end of the rotating rod 13 is connected to a threaded rod 14, and one end of the threaded rod 14 is fixedly connected to one end of the rotating rod 13, and a compression spring 15 is provided on one side surface of the protective baffle 12, and the number of the compression springs 15 is set to be several, one end of the compression spring 15 is fixedly connected to the protective baffle 12, and the other end of the compression spring 15 is movably connected to the outer surface of the shell 1, the number of the sliding rod 5 and the sliding groove 6 are both set to two, and the bottom of the sliding rod 5 is fixedly connected to the top surface of one end of the connecting rod 7, so as to prevent external objects from hitting the shell 1 and causing the connecting plug 2 to be misplaced or the electronic components inside the shell 1 to be damaged, thereby playing a buffering role and improving the practicality of the device.

[0024] Working principle of the utility model: when the device is in use, first insert the connecting plug 2 directly into the socket. When the connecting plug 2 contacts the socket, the slider 10 on the outside of the connecting plug 2 will be squeezed into the inside of the connecting plug 2 under the pressure of the socket, thereby completing the clamping connection between the connecting plug 2 and the socket. When the connecting plug 2 is connected to the socket, the slider 10 will rise upward to achieve the clamping connection between the connecting plug 2 and the inside of the socket. When it is necessary to separate the connecting plug 2 from the socket, push the slide bar 5, and use the slide bar 5 to drive the connecting rod 7 to slide inside the slide groove 6, and then the connecting rod 7 drives the slider 10 at one end thereof to move forward. Since the cross-section of the slider 10 is a triangle, the slider 10 will gradually shrink inside the connecting plug 2 when moving forward, and then the connecting plug 2 can be separated from the socket, thereby improving the overall stability of the device.
