Description

Technical Field

[0001] This utility model relates to the field of electronic controller technology, and in particular to a waterproof controller with a partition layer. Background Technology

[0002] Controllers, as electronic products, are widely used in our daily lives. Because they are electronic products, waterproof structural design is crucial during use. Existing controllers typically have a sealing ring at the connection between the housing and the cover, and another sealing ring for the wires where they enter – this is the most common structure. While this existing design provides some waterproofing, it is not ideal, especially in more extreme environments such as immersion in water, where leakage is common. High humidity levels also allow moisture to penetrate. The main reason is that although sealing rings are used at the wire connections, the wires pulling during use inevitably deforms the sealing rings, creating conditions for water infiltration. Therefore, we urgently need to design a controller with superior waterproofing that can withstand various extreme environments. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waterproof controller with a layered enclosure, comprising a housing and a cover integrally formed. The housing has a mounting groove in the middle for accommodating a circuit board, and isolation grooves are provided on both sides of the housing. A first channel is provided between the mounting groove and the isolation groove to allow wires to pass through, and a second channel is provided on the other side of the isolation groove to penetrate the housing wall and allow wires to pass through. The first channel and the second channel are respectively provided with wire sealing rings that wrap around the wires.

[0004] The controller requires wiring connections, and the main area prone to leakage is the wiring connection. An installation groove is set up to install the circuit board, and isolation grooves are set on both sides of the installation groove. The wires enter the installation groove and connect to the circuit board through the first and second channels, and wire sealing rings are set in the first and second channels respectively. The isolation grooves form a closed cavity isolation area. External water must enter through the two wire sealing rings before it can enter the installation groove, which provides a double waterproof effect. Moreover, the air pressure inside the sealed shell can better prevent water from entering the shell.

[0005] Preferably, a sealing groove is provided on the upper end of the inner wall of the housing at the top of the mounting groove, and a matching cover sealing ring is provided on the sealing groove.

[0006] A sealing ring is installed around the mounting groove to further enhance the sealing effect of the mounting groove and ensure that there is a certain air pressure inside the mounting groove to prevent external water from entering.

[0007] Preferably, the mounting groove is provided with at least two positioning posts for positioning the circuit board, the cover is provided with support posts corresponding to the positions of the positioning posts, and the end of the support post is provided with an embedding groove that matches the end of the positioning post.

[0008] The positioning posts and support posts work together to facilitate the positioning and fixing of the circuit board, avoiding misalignment and displacement after installation.

[0009] Preferably, the mounting slot is provided with a plurality of support blocks for supporting the circuit board.

[0010] Support blocks are provided to support the circuit board. The clamping of the support blocks and support columns clamps and fixes the circuit board in the vertical direction, preventing the circuit board from loosening inside the housing.

[0011] Preferably, the support blocks are arranged in a rectangular array or a ring array.

[0012] An array arrangement can provide more even support to the circuit board, avoiding uneven stress.

[0013] Preferably, the center points of the first channel and the second channel are on the same straight line and have the same area and shape.

[0014] The first and second channels are arranged in a straight line, which facilitates the passage of wires and also prevents the wire sealing ring from deforming due to bending of the wires, thus affecting the sealing effect.

[0015] Preferably, the cover is provided with a pressable flexible button, the cover is provided with a placement groove for installing the flexible button, the placement groove is provided with a button sealing area that protrudes from all sides inward, and the flexible button is provided with a button sealing groove corresponding to the button sealing area.

[0016] The flexible button is the switch of the controller. It is designed to be flexible so that when the button sealing area matches the button sealing groove, it can utilize the elastic sealing effect, which is the same as the sealing principle of the sealing ring.

[0017] Preferably, the wire sealing ring is provided with multiple wire holes that allow a single wire to pass through, and the wire sealing ring is also provided with a waterproof sealing groove surrounding the body, the waterproof sealing groove being matched and fixedly connected to the first channel and the second channel respectively.

[0018] Each wire sealing ring allows only one matching wire to pass through each wire hole, which better ensures the sealing effect.

[0019] Preferably, the housing is provided with a lower fitting area surrounding the housing, and the cover is provided with an upper fitting area surrounding the cover and corresponding to the lower fitting area; the lower fitting area outside the isolation groove is provided with a sealing protrusion, and the upper fitting area is provided with a sealing groove corresponding to the sealing protrusion.

[0020] The upper and lower fitting areas can seal the installation of the shell and cover, and the sealing protrusions and sealing grooves can further seal the isolation groove.

[0021] Preferably, the shell and the cover are fixedly connected by screws, pins, ultrasonic welding or hot pressing.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] This utility model is provided with an installation groove for mounting circuit boards, and isolation grooves are provided on both sides of the installation groove as sealed buffer zones. The isolation grooves form a closed cavity isolation area. External water must enter the installation groove through two wire sealing rings, which plays a double waterproof role. Moreover, the sealed shell and cover encapsulation structure will form air pressure inside the encapsulation when water enters, which can better prevent water from entering the shell.
