Description

Technical Field

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

[0002] In daily life, various electrical appliances bring us a lot of convenience; and all kinds of electrical appliances are inseparable from electricity when in use. For the convenience and safety of use, plugs are installed on the electrical appliances, and correspondingly, there are sockets that can supply electricity. The plug includes an insulating housing and two conductive columns (or conductive plates). The socket includes an insulating seat body. A jack is provided on the seat body. A conductive sheet is provided in the jack. When the conductive column of the plug is inserted into the jack of the socket, the conductive column of the plug contacts the conductive sheet in the jack of the socket to achieve electrical conduction.

[0003] In the prior art, there are inevitably gaps at the connection between the plug and the socket. If water vapor or dust enters the gaps between the plug and the socket, potential safety hazards may occur. 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 includes an outer box and an auxiliary mechanism.

[0006] The outer box is arranged with the opening facing upward; a core body is inserted into the outer box; two symmetrically arranged jacks are provided on the upper end surface of the core body; the axes of the jacks are arranged vertically; the openings of the jacks face upward; conductive sheets are provided in the jacks; the auxiliary mechanism includes a plugging component and a negative pressure component.

[0007] The plugging component is arranged in the jack and includes a sealing ring, a partition plate, and an air pipe; the sealing ring is fixed on the upper end of the core body and is arranged outside the opening of the jack; the sealing ring is an elastic ring; the partition plate slides in the jack in a sealed manner; a top push spring is arranged below the partition plate; the upper end of the top push spring is fixedly connected to the partition plate, and the lower end is fixedly connected to the bottom wall of the jack; the partition plate divides the jack into an upper cavity and a lower cavity; the air pipe is in a U shape with the opening facing the jack; the air pipe is arranged inside the core body and is at the lower end of the side wall of the jack; the two pipe orifices of the air pipe are arranged vertically and are both communicated with the jack; in the process that the conductive column of the plug pushes the partition plate downward to compress the air in the lower cavity against the elastic force of the top push spring, when the housing of the plug presses against the sealing ring, the partition plate seals the upper pipe orifice above the air pipe, and the housing of the plug and the sealing ring are in sealed cooperation to seal the upper cavity.

[0008] The negative pressure component is arranged between the two jacks; when the shell of the plug seals the upper cavity, the negative pressure component sucks the plug shell, drives the plug to drive 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 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. The negative pressure component includes a negative pressure hole, a sealing ring, a sliding disk, and an electromagnet. The opening of the negative pressure hole is arranged upward between the two jacks; the sealing ring is a rubber ring, fixed at 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. The sliding disk seals and slides in the negative pressure hole; the sliding disk is made of a metal material that can be adsorbed by magnetic force; a reset spring is arranged below 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. 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] Furthermore, a plurality of slots are arranged in the outer box; a core body is inserted into each slot.

[0016] Furthermore, a cover is fixed on the opening of the outer box to prevent the inner core from being exposed.

[0017] Furthermore, the sealing ring and the sealing ring are both made of rubber.

[0018] The beneficial effects of the present invention are:

[0019] 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.

[0020] 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 outer box 100 is arranged with its opening facing upward; an inner core body 200 is inserted into the outer box 100; two symmetrically arranged jacks 210 are provided on the upper end surface of the inner core body 200; the axes of the jacks 210 are arranged vertically; the openings of the jacks 210 face upward; conductive sheets are provided in the jacks 210; a cover 110 is fixed on the opening of the outer box 100. The cover 110 is used to prevent the inner core body 200 from being exposed. The auxiliary mechanism includes a plugging component and a negative pressure component.

[0031] The plugging component is arranged in the jack 210 and includes a sealing ring 310, a partition 320, an air pipe 330 and an anti-misoperation structure; the sealing ring 310 is fixed on the upper end of the inner core body 200 and is arranged outside the opening of the jack 210; the sealing ring 310 is an elastic ring; the sealing ring 310 is in the shape of a funnel with the small end facing downward, so that the sealing ring 310 functions as a suction cup to improve the sealing effect between the housing of the plug and the sealing ring 310.

[0032] The partition plate 320 slides in the jack 210 in a sealed manner; a pushing spring 340 is provided below the partition plate 320; the upper end of the pushing spring 340 is fixedly connected to the partition plate 320, and the lower end is fixedly connected to the bottom wall of the jack 210; the partition plate 320 divides the jack 210 into an upper cavity and a lower cavity; the air pipe 330 is in a U shape with an opening facing the jack 210; the air pipe 330 is disposed inside the inner core body 200 and is at the lower end of the side wall of the jack 210; the two pipe orifices of the air pipe 330 are arranged vertically and are both communicated with the jack 210; during the process that the conductive column of the plug pushes the partition plate 320 to move downward against the elastic force of the pushing spring 340 to compress the air in the lower cavity, when the housing of the plug presses against the sealing ring 310, the partition plate 320 seals the upper pipe orifice of the air pipe 330, and the housing of the plug and the sealing ring 310 are in sealing fit to seal the upper cavity.

[0033] The anti-mis-touch structure is used to ensure that when the conductive columns are inserted into the two jacks 210 simultaneously and synchronously, the partition plates 320 in the two jacks 210 can move downward synchronously to avoid mis-touch. The anti-mis-touch structure includes a guiding groove 351 and a synchronous groove 352; the guiding groove 351 is provided on the side wall of the jack 210; the partition plate 320 is in sliding fit with the guiding groove 351; the cross-section of the guiding groove 351 is rectangular.

[0034] The synchronous groove 352 is disposed inside the inner core body 200 and is between the two jacks 210; the synchronous groove 352 is communicated with the guiding groove 351; a synchronous rod 353 is provided in the synchronous groove 352; both ends of the synchronous rod 353 are fixedly connected to the partition plate 320. A fitting block is slidably provided in the guiding groove 351; the fitting block is a cube; the fitting block is fixedly connected to the partition plate 320. When a foreign object is inserted into only one jack 210, under the action of the pushing spring 340, the guiding groove 351 and the synchronous rod 353, the two partition plates 320 are unevenly stressed and tilted, and under the limitation of the guiding groove 351, the partition plates 320 are prevented from continuing to move downward.

[0035] The negative pressure assembly is provided between the two jacks 210; when the housing of the plug seals the upper cavity, the negative pressure assembly sucks the housing of the plug, driving the plug to drive the partition plate 320 to move downward through the conductive column, so that the upper pipe orifice of the air pipe 330 is communicated 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 potential safety hazards.

[0036] The negative pressure component includes a negative pressure hole 410, a sealing ring 420, a sliding disk 430, and an electromagnet 440. The negative pressure hole 410 is provided between two jacks 210 with its opening facing upward; the sealing ring 420 is a rubber ring, fixed to the upper end of the inner core body 200 and provided outside the opening of the negative pressure hole 410; the sealing ring 420 is an elastic ring. The sealing ring 420 is in the shape of a funnel with the small end facing downward, so that the sealing ring 420 functions as a suction cup, improving the sealing effect between the housing of the plug and the sealing ring 420. Both the sealing ring 420 and the sealing ring 310 are made of rubber.

[0037] The sliding disk 430 is hermetically slidable within the negative pressure hole 410; the sliding disk 430 is made of a metal material that can be magnetically adsorbed, such as metallic iron or nickel alloy; a return spring 450 is provided below the sliding disk 430; the upper end of the return spring 450 is fixedly connected to the sliding disk 430, and the lower end is fixedly connected to the bottom wall of the negative pressure hole 410; the sliding disk 430 divides the negative pressure hole 410 into an upper hole portion and a lower hole portion; the lower hole portion communicates with the outside.

[0038] The electromagnet 440 is fixed to the lower end of the negative pressure hole 410; a proximity switch is provided on one side of the negative pressure hole 410; when the housing of the plug moves to abut against the sealing ring 420 to hermetically fit the upper hole portion of the negative pressure hole 410, the proximity switch energizes the electromagnet 440 to make it magnetic. The electromagnet 440 overcomes the return spring 450 by magnetic force to drive the sliding disk 430 to move downward. Since the housing of the plug and the sealing ring 420 are sealed, a negative pressure is generated in the upper hole portion of the negative pressure hole 410, and the negative pressure sucks the housing of the plug, driving the plug to drive the partition plate 320 to move downward through the conductive column. And when the connection between the conductive column and the conductive sheet overheats, the high temperature causes the magnetic force of the electromagnet 440 to fail, and the return spring 450 releases its force to drive the sliding disk 430 to move upward, and the negative pressure in the upper hole portion of the negative pressure hole 410 disappears, so that the top push spring 340 resets to drive the partition plate 320 to move upward. When the partition plate 320 moves upward, the conductive column of the plug is ejected from the jack 210, disconnecting the plug from the socket. This constitutes overheat protection.

[0039] In this embodiment, a plurality of slots are provided inside the outer box 100; the inner core body 200 is inserted into each slot. This realizes meeting different power consumption requirements.

[0040] In combination with the above embodiments, the use principle and working process of the present invention are as follows: when in use, when 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 presses 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; when the shell of the plug moves to abut against the sealing ring 420 to seal the upper hole of the negative pressure hole 410, the proximity switch energizes the electromagnet 440 and has magnetism. 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.
