Description

Technical Field

[0001] The invention relates to the technical field of power sockets, and in particular to a waterproof and dustproof power socket. Background Art

[0002] In daily life, various electrical appliances bring us many conveniences; and various electrical appliances cannot be separated from electricity when in use. For the convenience and safety of use, plugs are installed on electrical appliances, and the corresponding ones are sockets that can supply electricity. The plug includes an insulating shell and two conductive posts (or conductive plates). The socket includes an insulating seat. The seat is provided with a socket. A conductive sheet is provided in the socket. When the conductive post of the plug is inserted into the socket of the socket, the conductive post of the plug and the conductive sheet in the socket of the socket are in contact to achieve electrical conduction.

[0003] In the prior art, there is inevitably a gap between the plug and the socket. If water vapor or dust enters the gap between the plug and the socket, it may cause a safety hazard. Summary of the invention

[0004] The present invention provides a waterproof and dustproof power socket to solve the above problems.

[0005] A waterproof and dustproof power socket of the present invention adopts the following technical solution: a waterproof and dustproof power socket comprises an outer box and an auxiliary mechanism.

[0006] The outer box opening is arranged upward; the inner core is inserted in the outer box; two symmetrically arranged sockets are arranged on the upper end surface of the inner core; the socket axes are arranged up and down; the socket opening is arranged upward; a conductive sheet is arranged in the socket; the auxiliary mechanism includes a blocking component and a negative pressure component.

[0007] The sealing assembly is arranged in the socket, including a sealing ring, a partition, and an air pipe; the sealing ring is fixed at the upper end of the inner core body and is arranged outside the opening of the socket; the sealing ring is an elastic ring; the partition seals and slides in the socket; a push spring is arranged below the partition; the upper end of the push spring is fixedly connected to the partition, and the lower end is fixedly connected to the bottom wall of the socket; the partition divides the socket into an upper cavity and a lower cavity; the air pipe is U-shaped with its opening facing the socket; the air pipe is built into the inner core body and is located at the lower end of the side wall of the socket; the two pipe openings of the air pipe are arranged up and down and are both connected to the socket; in the process that the conductive column of the plug overcomes the elastic force of the push spring to push the partition downward to compress the air in the lower cavity, when the shell of the plug presses against the sealing ring, the partition blocks the pipe opening above the air pipe, and the shell of the plug and the sealing ring are sealed to seal the upper cavity.

[0008] The negative pressure component is arranged between the two sockets; when the shell of the plug seals the upper cavity, the negative pressure component sucks the plug shell, driving the plug to move the partition downward through the conductive column, so that the pipe opening above the air pipe is connected with the upper cavity, so that the high-pressure gas in the lower cavity is filled into the upper cavity through the air pipe, so that the air pressure in the socket is greater than the external atmospheric pressure, effectively preventing external water vapor and dust from entering the gap between the conductive column of the plug and the conductive sheet in the socket, and preventing safety hazards.

[0009] Furthermore, the negative pressure assembly includes a negative pressure hole, a sealing ring, a sliding plate, and an electromagnet. The negative pressure hole is opened upward and arranged between the two jacks; the sealing ring is a rubber ring, fixed to the upper end of the inner core body and arranged outside the opening of the negative pressure hole; the sealing ring is an elastic ring.

[0010] The sliding disk seal slides in the negative pressure hole; the sliding disk is made of metal material that can be attracted by magnetic force; a reset spring is arranged under the sliding disk; the upper end of the reset spring is fixedly connected to the sliding disk, and the lower end is fixedly connected to the bottom wall of the negative pressure hole; the sliding disk divides the negative pressure hole into an upper hole part and a lower hole part; the lower hole part is connected to the outside.

[0011] The electromagnet is fixed at the lower end of the negative pressure hole; a proximity switch is provided on one side of the negative pressure hole; when the shell of the plug moves to abut against the sealing ring to seal the upper hole of the negative pressure hole, the proximity switch energizes the electromagnet and becomes magnetic. The electromagnet overcomes the reset spring through magnetic force to drive the sliding plate downward. Due to the seal between the shell of the plug and the sealing ring, negative pressure is generated in the upper hole of the negative pressure hole. The negative pressure draws the shell of the plug and drives the plug to drive the partition downward through the conductive column. When the connection between the conductive column and the conductive sheet is overheated, the high temperature makes the magnetic force of the electromagnet ineffective, the reset spring releases force to drive the sliding plate upward, and the negative pressure in the upper hole of the negative pressure hole disappears, so that the push spring resets and drives the partition upward. When the partition moves upward, the conductive column of the plug is ejected from the jack, so that the plug is disconnected from the socket, forming an overheating protection.

[0012] Furthermore, the sealing ring is in a funnel shape with the small end facing downward, so that the sealing ring acts as a suction cup, thereby improving the sealing effect between the housing of the plug and the sealing ring.

[0013] Furthermore, the sealing ring is in the shape of a funnel with the small end facing downward, so that the sealing ring acts as a suction cup, thereby improving the sealing effect between the housing of the plug and the sealing ring.

[0014] Furthermore, the blocking component also includes an anti-accidental touch structure; the anti-accidental touch structure is used to prevent accidental touch when the conductive pillars are inserted into the two sockets simultaneously and synchronously, so that the partitions in the two sockets can move down synchronously.

[0015] Furthermore, the anti-mistouch structure includes a guide groove and a synchronization groove; the guide groove is arranged on the side wall of the jack; the partition plate and the guide groove are slidably matched; and the cross section of the guide groove is rectangular.

[0016] The synchronous groove is arranged in the inner core and between the two jacks; the synchronous groove is connected to the guide groove; a synchronous rod is arranged in the synchronous groove; and both ends of the synchronous rod are fixedly connected to the partition. When a foreign object is inserted into only one jack, the two partitions are unevenly stressed and tilted under the action of the push spring, the guide groove and the synchronous rod, and the partition is prevented from moving further downward under the limit of the guide groove.

[0017] Furthermore, a matching block is slidably provided in the guide groove; the matching block is a cube; and the matching block and the partition are fixedly connected.

[0018] Furthermore, a plurality of slots are arranged in the outer box; a core body is inserted into each slot.

[0019] Furthermore, a cover is fixed on the opening of the outer box to prevent the inner core from being exposed.

[0020] Furthermore, the sealing ring and the sealing ring are both made of rubber.

[0021] The beneficial effects of the present invention are: 1. When the plug shell seals the upper cavity, the negative pressure component draws suction from the plug shell, driving the plug to move the partition downward through the conductive column, so that the pipe opening above the air pipe is connected to the upper cavity, so that the high-pressure gas in the lower cavity is filled into the upper cavity through the air pipe, so that the air pressure in the jack is greater than the external atmospheric pressure, effectively preventing external water vapor and dust from entering the gap between the conductive column of the plug and the conductive sheet in the jack, and preventing safety hazards.

[0022] 2. When the connection between the conductive column and the conductive sheet is overheated, the high temperature makes the magnetic force of the electromagnet ineffective, the reset spring releases force to drive the sliding plate upward, and the negative pressure in the upper hole of the negative pressure hole disappears, causing the push spring to reset and drive the partition to move up. When the partition moves up, the conductive column of the plug is ejected from the socket, disconnecting the plug from the socket, thus forming an overheating protection.

[0030] The partition 320 is sealed and slides in the socket 210; a push spring 340 is provided under the partition 320; the upper end of the push spring 340 is fixedly connected to the partition 320, and the lower end is fixedly connected to the bottom wall of the socket 210; the partition 320 divides the socket 210 into an upper cavity and a lower cavity; the air pipe 330 is U-shaped with its opening facing the socket 210; the air pipe 330 is built into the inner core 200 and is located at the lower end of the side wall of the socket 210; the two pipe openings of the air pipe 330 are arranged up and down, and both are connected to the socket 210; in the process that the conductive column of the plug overcomes the elastic force of the push spring 340 to push the partition 320 downward to compress the air in the lower cavity, when the shell of the plug is pressed against the sealing ring 310, the partition 320 blocks the pipe opening above the air pipe 330, and the shell of the plug and the sealing ring 310 are sealed to seal the upper cavity.

[0031] The anti-mistaken touch structure is used to prevent mis-touch when the conductive pillars are inserted into the two sockets 210 simultaneously and synchronously, so that the partitions 320 in the two sockets 210 can move down synchronously to avoid mis-touch.

A matching block is slidably arranged in the guide groove 351; the matching block is a cube; and the matching block is fixedly connected to the partition 320. When a foreign object is inserted into only one of the insertion holes 210, under the action of the push spring 340, the guide groove 351 and the synchronization rod 353, the two partitions 320 are unevenly stressed and tilted, and the partition 320 is prevented from continuing to move downward under the limit of the guide groove 351.

[0033] The negative pressure component is arranged between the two jacks 210; when the shell of the plug seals the upper cavity, the negative pressure component sucks the plug shell, driving the plug to move downward through the conductive column to drive the partition 320, so that the pipe opening above the air pipe 330 is connected with the upper cavity, so that the high-pressure gas in the lower cavity is filled into the upper cavity through the air pipe 330, so that the air pressure in the jack 210 is greater than the external atmospheric pressure, effectively preventing external water vapor and dust from entering the gap between the conductive column of the plug and the conductive sheet in the jack 210, and preventing safety hazards.

[0034] The negative pressure assembly includes a negative pressure hole 410, a sealing ring 420, a sliding plate 430, and an electromagnet 440. The negative pressure hole 410 is opened upward and arranged between the two jacks 210; the sealing ring 420 is a rubber ring, fixed to the upper end of the inner core 200, and arranged outside the opening of the negative pressure hole 410; the sealing ring 420 is an elastic ring.

The electromagnet 440 overcomes the reset spring 450 through magnetic force to drive the sliding plate 430 downward. Since the housing of the plug and the sealing ring 420 are sealed, negative pressure is generated in the upper hole of the negative pressure hole 410, and the negative pressure sucks the housing of the plug, driving the plug to drive the partition 320 downward through the conductive column.

The electromagnet 440 overcomes the reset spring 450 through magnetic force to drive the sliding plate 430 downward. Due to the sealing of the shell of the plug and the sealing ring 420, negative pressure is generated in the upper hole of the negative pressure hole 410, and the negative pressure sucks the shell of the plug, driving the plug to drive the partition 320 downward through the conductive column. The pipe opening above the air pipe 330 is connected to the upper cavity, so that the high-pressure gas in the lower cavity is filled into the upper cavity through the air pipe 330, so that the air pressure in the jack 210 is greater than the external atmospheric pressure, effectively preventing external water vapor and dust from entering the gap between the conductive column of the plug and the conductive sheet in the jack 210, and preventing potential safety hazards. When the connection between the conductive column and the conductive sheet is overheated, the high temperature makes the magnetic force of the electromagnet 440 ineffective, and the reset spring 450 releases the force to drive the sliding plate 430 to move upward, and the negative pressure in the upper hole of the negative pressure hole 410 disappears, so that the push spring 340 is reset to drive the partition 320 to move upward. When the partition 320 moves upward, the conductive column of the plug is ejected from the jack 210, so that the plug is disconnected from the socket, forming an overheating protection.
