Embodiment

[0018] refer to Figure 1-2 , a safety plug to prevent pulling, comprising a socket case 1, the outer wall of the socket case 1 is connected with a segmented plate 2 through a compression spring 3, the segmented plate 2 and the socket case 1 are jointly fixed with a connecting belt 4, and the connecting belt 4 is flexible Made of cloth, the deformation ability is relatively poor, and basically no deformation will occur after being pulled, which ensures the stability of the position of the socket case 1 and the section plate 2. The side wall of the section plate 2 is fixed with two insertion rods 5, two The insertion rods 5 both pass through the side wall of the insertion case 1 and extend to the inside of the insertion case 1, and the two insertion rods 5 are slidably connected with the insertion case 1. The inner wall of the groove 6 is connected with the connecting rod 8 through the return spring 7, and the inner wall of the socket case 1 is fixed with two connecting rods 9 ...

Abstract

The invention discloses a pull-proof safety plug, comprising an insert shell, an outer wall of the insert shell is connected with a segment plate through a compression spring, the segment plate and the insert shell are jointly fixed with a connecting band, and the segment plate is Two insertion rods are fixed through the side wall of the plug, both of which penetrate the side wall of the plug case and extend to the inside of the plug case, and the two plug rods are slidably connected with the plug case. The side walls of the two runners are provided with chutes, and the inner walls of the two chutes are connected with receiving rods through return springs. The advantages are: in the present invention, by filling the inside of the liquid storage cavity with the electrorheological fluid, the electrorheological fluid will solidify and expand after being energized, so that the limit belt is pushed by the electrorheological fluid to change in shape, and the solidified current The changing liquid forms a limit rod extending out of the insertion rod, which effectively restricts the movement of the insertion rod, so that the insertion rod cannot be directly separated from the socket under external force, thus ensuring the stability of the power connection process.

Description

technical field [0001] The invention relates to the technical field of plugs, in particular to a pull-proof safety plug. Background technique [0002] The connectors of general electronic products and the plugs of electrical appliances are called plugs. With the popularization of electronic products, more and more plugs are used; [0003] In the actual use of existing plugs, the stability of the power connection generally depends on the clamping force of the reeds inside the socket, and after long-term use, the reeds will wear out, and poor contact will occur, and the plug is in use. During the process, due to the existence of the external connecting wire, the plug is easily pulled accidentally, thus loosening and separating from the socket, resulting in a power outage, and a sudden power outage of many products will cause a large loss, so there is an urgent need for a device that can prevent Pull the disconnected plug. Contents of the invention [0004] The purpose of t...
