Description
Technical Field
The utility model relates to the field of membrane switch structures, in particular to a fine circuit membrane switch structure.
Background
The gaps of the keyboard shell arranged outside the traditional keyboard membrane switch are basically filled with waterproof glue for waterproofing, and an air passage is needed to be manufactured at the edge of glue for ensuring normal pressing and ventilation of keyboard keys and comfortable hand feeling, and the air passage is easy to be fed with water to cause short circuit without functions during the waterproof test of the membrane switch; however, the keyboard membrane switches in the market at present are designed by adding an air passage on the edge of waterproof glue (as shown in figure 1); the main reasons that smooth ventilation and water resistance are not achieved by pressing exist, meanwhile, the air passage distance is designed to be smaller to ensure the water resistance effect, and the requirements on the process are higher due to certain difficulty in development, production and manufacturing.
Disclosure of Invention
In order to solve the problems, the utility model provides the following scheme:
the utility model provides a novel waterproof exhaust structure of keyboard membrane switch, includes keyboard casing, membrane switch structure and waterproof exhaust structure, and membrane switch structure includes the PET that the multilayer printed has the circuit, offers the interval that is used for the exhaust between the PET, and membrane switch structure sets up in the keyboard casing, has scribbled waterproof glue in the keyboard casing edge gap, and the keyboard casing edge has offered the hole that is used for setting up waterproof exhaust structure, waterproof exhaust structure includes waterproof air flue, and waterproof air flue is the setting of snakelike reciprocal buckling, and waterproof air flue one end passes the hole and the external intercommunication at keyboard casing edge, and the other end passes interval and the PET intercommunication between the PET; a water absorption component is arranged in the waterproof air passage; the inner diameter of the waterproof airway is 1mm.
Further, the waterproof airway ensures an inner diameter width of 1mm.
Further, the water absorbing component is one of water absorbing paster, water absorbing ink or water absorbing glue which is arranged in the waterproof air passage.
The utility model has the beneficial effects that: the waterproof air passage is arranged in the keyboard shell and is used for communicating PET in the membrane switch structure with the outside, so that the key of the keyboard is ensured to be pressed smoothly, when the key is pressed down, gas in the PET is discharged through the waterproof air passage, and when the key rebounds, the outside gas is supplemented back into the PET through the waterproof air passage; meanwhile, the water absorption component is arranged in the waterproof air passage, if water enters the waterproof air passage, the water absorption component absorbs and expands the water, the water is prevented from continuously entering the PET, the phenomenon that a circuit in the PET is shorted with the water is avoided, the water absorption component is reduced after being dried, and the waterproof air passage is ventilated again normally.
Drawings
FIG. 1 is a schematic diagram of a prior art keyboard ventilation structure;
FIG. 2 is a schematic diagram of the structure of the present utility model;
fig. 3 is a schematic view of the waterproof venting structure in fig. 2.
In the figure: 1. a keyboard housing; 2. a waterproof exhaust structure; 3. waterproof air passages; 4. a water absorbing component; and L, inner diameter width of the waterproof airway.
Detailed Description
The utility model will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Example 1: as shown in figures 1-2 of the drawings,
the utility model provides a novel waterproof exhaust structure of keyboard membrane switch, includes keyboard casing 1, membrane switch structure and waterproof exhaust structure 2, and membrane switch structure includes the PET that the multilayer printed has the circuit, sets up the interval that is used for the exhaust between the PET, and membrane switch structure sets up in keyboard casing 1, and keyboard casing 1 edge gap is scribbled waterproof glue, and keyboard casing 1 edge has set up the hole that is used for setting up waterproof exhaust structure 2, waterproof exhaust structure 2 includes waterproof air flue 3, and waterproof air flue 3 is the setting of snakelike reciprocal buckling, and the hole and the external intercommunication at keyboard casing 1 edge are passed to waterproof air flue 3 one end, and the interval and the PET intercommunication between the other end pass PET; a water absorption component 4 is arranged in the waterproof air passage 3; the inner diameter of the waterproof air passage 3 is 1mm.
Further, the inner diameter of the waterproof air duct 3 is at least 1mm wide.
Further, the water absorbing component 4 is one of water absorbing paster, water absorbing ink or water absorbing glue which is arranged in the waterproof air passage 3.
The waterproof air passage 3 is arranged in the keyboard shell 1 and is used for communicating PET in the membrane switch structure with the outside, so that keys of the keyboard are smoothly pressed, when the keys are pressed down, gas in the PET is discharged through the waterproof air passage 3, and when the keys rebound, the outside gas is supplemented into the PET through the waterproof air passage 3; meanwhile, the water absorbing component 4 is arranged in the waterproof air channel 3, if water enters the waterproof air channel 3, the water absorbing component 4 absorbs and expands the water, so that the water is prevented from continuously entering the PET, the short circuit of a circuit in the PET when the water is met is avoided, the water absorbing component 4 is reduced after being dried, and the waterproof air channel 3 is ventilated again normally.
Finally, it should be noted that the above list is only specific embodiments of the present utility model. Obviously, the utility model is not limited to the above embodiments, but many variations are possible. All modifications directly derived or suggested to one skilled in the art from the present disclosure should be considered as being within the scope of the present utility model.
