Problems solved by technology

[0002] Plugs and sockets are common items in people's daily life. With the increase of household appliances, the number of sockets in the family also increases. Some household appliances need long-term power supply, such as refrigerators, water heaters, refrigerators, etc., while others "Plug and use", such as hair dryers, fans, electric blankets, etc., for the convenience of taking and using, most of these "plug and use" electrical appliances have long power cords. When people accidentally pull or shake the power cord, The plug will also shake under the influence of the force, and the reeds in some old sockets have a small clamping force, and the shaking of the power cord is likely to cause the plug to loosen from the socket
[0003] Most of the existing anti-loosening sockets use the method of changing the shape of the metal sheet on the plug to reduce the loosening of the plug, but as the use time increases, the clamping force of the reed will still gradually weaken. The reed with large holding force, the plug is difficult to insert or pull out, which brings inconvenience to people's use. For this reason, we propose an anti-loosening plug and socket

Embodiment 1

[0028] refer to Figure 1-4 , an anti-loosening plug and socket, including a cover 1, a housing 4 and two conductive sheets 8, two main connectors 10 are symmetrically arranged in the casing 4, each conductive sheet 8 runs through the casing 4 and is connected to the The corresponding main joints 10 are electrically connected, and the control circuit board 3 and the U-shaped cylinder 6 are respectively fixed on the inner top wall and the inner bottom wall of the housing 4. The U-shaped cylinder 6 includes a horizontal tube and two vertical tubes. The side wall is provided with a first through groove and an insulating shrapnel 13 is sealed and arranged at the first through groove, and a circular plate 11 is sealed and slid in each vertical tube, and an insulating shrapnel 11 is connected to the lower surface of each circular plate 11 . rods 7, and the lower end of each insulating rod 7 runs through the bottom wall of the housing 4 and extends to the outside of the housing 4, th...

Embodiment 2

[0038] refer to Figure 5-6 , the present embodiment differs from Embodiment 1 in that: an arc-shaped groove is opened on the press cover 1, and a converter 20 is rotatably installed in the arc-shaped groove. A receiver 22 is embedded on the groove wall of the groove, and the receiver 22 is electrically connected to the control circuit board 3, and the converter 20 includes an outer protective cover and an inner permanent magnet;

[0039]The outer side of the protective cover is symmetrically coated with two colors, and the color distribution corresponds to the magnetic field distribution of the inner permanent magnet. The magnetic field distribution state of the permanent magnet at a certain time can be distinguished by the two colors.

[0040] The insulating column 15 includes an outer insulating sleeve and an inner magnetic column.

[0041] When this embodiment is in use, when the plug is plugged in, the converter 20 can be rotated so that the polarity of the inner permane...

Abstract

The invention discloses an anti-loosening plug, which comprises a press cover, a casing and two conductive sheets, two main joints are arranged symmetrically in the casing, each of the conductive sheets goes through the casing and is connected to the corresponding main connector. The joints are electrically connected, and a control circuit board and a U-shaped tube are respectively fixed on the inner top wall and the inner bottom wall of the housing. The U-shaped tube includes a horizontal tube and two vertical tubes. A first through-slot is opened and an insulating shrapnel is sealed and installed at the first through-slot. A circular plate is sealed and slidably arranged in each of the vertical tubes, and an insulating rod is connected to the lower surface of each of the circular plates. The invention can ensure that when the socket body is impacted, the plug can still be fixedly inserted on the socket body, effectively preventing the occurrence of poor contact caused by the loose plug; in addition, before pulling out the plug, turn the converter to make it in a specific position, Makes it easier to pull out the plug.

Description

technical field [0001] The invention relates to the technical field of electric devices, in particular to an anti-loosening plug and socket.
