The present disclosure relates to the technical field of sockets, in particular to an internal waterproof and dustproof module.
Socket, also referred to as power socket or switch socket, refers to a socket with one or more circuit connection wires that can be plugged. By the socket, various connection wires can be plugged. Generally, there are several modules inside a socket, allowing a plurality of plugs to be plugged into the socket simultaneously for operation. However, general modules have some disadvantages when used, for example, as follows:
When a general module is in use, a foreign object entering a device will directly come into contact with electrodes inside the module, causing a phenomenon that the foreign object is conductive. As a result, a certain potential safety hazard is posed to the device during use. At the same time, the device is poor in sealing property and cannot prevent water from entering the device.
The present disclosure aims to solve the above problems to provide an internal waterproof and dustproof module, which improves the problem that the existing internal waterproof and dustproof module has poor sealing property.
An internal waterproof and dustproof module is provided, including a front case and a protection door; the protection door is arranged inside the front case; a limiting post is arranged on a side surface of the front case; the limiting post penetrates through a middle case and a rear case in sequence; a sealing ring is arranged inside the middle case; and an L-pole connecting mechanism, an N-pole connecting mechanism, a first limiting mechanism, and a second limiting mechanism are respectively arranged inside the rear case. When the device is in use, the limiting post penetrates through the middle case and the rear case in sequence, and is then fixed by a bolt, so that the front case, the middle case, and the rear case are fixed. The sealing ring is made of a silica gel material, which can improve the sealing property of the device. The protection door can further improve the sealing property of the device.
Preferably, the L-pole connecting mechanism includes an L-pole copper sheet and a first connecting block; the L-pole copper sheet is arranged inside the rear case; the first connecting block is arranged on a side surface of the L-pole copper sheet; and the first connecting block is located inside the rear case. When the device is in use, the L-pole copper sheet is connected to an external line, and the L-pole copper sheet is connected to the first connecting block.
Preferably, a side surface of a second connecting block is connected with a second connecting plate; and a side surface of the second connecting plate is a slope. When the second connecting block is in contact with the first connecting block, the second connecting block can be communicated with the first connecting block, so that a current enters the second connecting block through the first connecting block, and then enters the second connecting plate through the second connecting block.
Preferably, the first limiting mechanism includes a first movable block and a first connecting plate; one side of the first movable block is connected with the rear case; the first connecting plate is arranged on a side surface of the first movable block; and an upper end of the rear case is connected with the first connecting block. When the first movable block moves upwards, the first movable block can be in contact with the first connecting block, so that the first connecting block is communicated with the first movable block, and the first movable block is connected to a surface of the first connecting plate.
Preferably, the second limiting mechanism includes a third connecting plate and a second movable block; the third connecting plate is located right below the second connecting plate; and the third connecting plate is arranged on a side surface of the second movable block. When the second connecting plate is in contact with the third connecting plate, a current can flow between the second connecting plate and the third connecting plate, and the current can also be conducted to the second movable block through the third connecting plate.
Preferably, the N-pole connecting mechanism includes a third connecting block and an N-pole copper sheet; the N-pole copper sheet is arranged inside the rear case; the third connecting block is arranged on a side surface of the N-pole copper sheet; the third connecting block is located inside the rear case; and the third connecting block is located right under the second movable block.
Preferably, a fourth connecting block is located below the third connecting block; a side surface of the fourth connecting block is connected with a fourth connecting plate; and the fourth connecting plate is located below the first connecting plate. The second movable block may drive the third connecting block to move when moving downwards, so that the third connecting block is in contact with the fourth connecting block. The first connecting plate may be in contact with the fourth connecting plate when moving downwards, so that the current can flow between the first connecting plate and the fourth connecting plate.
Preferably, a grounding copper sheet is arranged on a side surface of the rear case. The grounding copper sheet can directly conduct the current to the ground, which ensures that the device has no leakage phenomenon.
The present disclosure has the beneficial effects:
1. A foreign object or a substandard pin can only be plugged into the second connecting plate and the third connecting plate or plugged into the first connecting plate and the fourth connecting plate when plugged into the device, which cannot drive the first movable block and the second movable block to move. Therefore, no electric conduction phenomenon occurs when the foreign object or the substandard pin is plugged into the device.
2. The protection door and the sealing ring can be used to improve the sealing property of the device, which avoids water from entering the device to affect the use of the device.
