Abstract
The utility model relates to a waterproof and breathable bolt capable of avoiding electromagnetic wave penetrating interference. The waterproof and breathable bolt capable of avoiding electromagnetic wave penetrating interference comprises a body, wherein an axial through hole is formed inside the body, the body sequentially comprises a head portion, a portion for being screwed and a screw from top to bottom, the end face of the head portion is provided with a waterproof and breathable film which covers and seals the through hole, a protective cover is arranged on the head portion of the body in a pressing mode, and miniature holes are evenly distributed in the protective cover. Through physical characteristics and chemical characteristics of a miniature hole thin film which is made of expanded polytetrafluoroethylene, the waterproofing effect, the breathability effect and the corrosion resistance effect of the bolt are achieved, and meanwhile the effect of well avoiding and shielding electromagnetic wave penetrating interference is achieved when the waterproof and breathable bolt is combined with the electric conductive bolt body.
Description
Technical field
The utility model relates to a kind of bolt, particularly a kind of waterproof and breathable bolt of anti-electromagnetic wave infiltration interference.
Background technique
The microporous membrane of expanded PTFE and modified film material have the microcellular structure of the perforation of interconnecting, and micropore diameter is at 0.01 ~ 20 μ m, and gas (containing water vapor molecule) can see through eptfe film and mutual convection current exchange release heat.And rainwater, salt fog, mist of oil and dust etc. can not see through eptfe film, simultaneously eptfe film have that chemical inertness is good, the excellent properties such as uvioresistant, nonflammable and high-low temperature resistant.
The product requirement such as electronic equipment and outdoor communication reaches IP65 grade (dust and water protection), and traditional device housings structure is totally enclosed environment, makes in the shell to carry out gas exchange and heat radiation with external environment condition.When electronic equipment works long hours and causes in the shell gas pressure rising pressure to increase, produce pressure difference with outside air, increase shell internal air pressure and electronic component stress, accelerate the finished product electronic component aging.Housing expands with heat and contract with cold simultaneously, so that rainwater and moist fog are invaded inside along seam, affects the reliability of electronic component and circuit long-term work.At present owing to precise electronic or outdoor communication equipment in order radiate heat and ventilate to offer hole, these pore space structures will cause the Electromagnetic Interference infiltration, the on the one hand equipment normal operation around the impact, the on the other hand normal performance of external its performance of Electromagnetic Interference, this is the difficult problem that precise electronic or outdoor communication equipment face complicated electromagnetic wave normal operation.
The model utility content
It is good that the purpose of this utility model provides a kind of water-proof breathable properties, and can permeate the waterproof and breathable bolt that the anti-electromagnetic wave that disturbs permeates interference by anti-electromagnetic wave.
The technological scheme that realizes the utility model purpose is: the utlity model has body; Described body interior has axial through hole; Described body comprises having head, the part of Gong tightening and screw rod from top to bottom successively; Be provided with the waterproof ventilated membrane that covers through hole on the end face of described head; Be pressed with protecting cover on the head of described body; Be evenly equipped with micro hole on the described protecting cover.
Above-mentioned waterproof ventilated membrane is pasted on the end face of head by pressure sensitive tape.
Above-mentioned waterproof ventilated membrane is the microporous membrane of expanded PTFE.
The part of Gong tightening on the above-mentioned body is coaxial six convex edges that are arranged on the body.
The utlity model has positive effect: (1) the utility model utilizes physics and the chemical characteristics of the microporous membrane of expanded PTFE, reached bolt waterproof and breathable, corrosion resistant effect, the bolt body in conjunction with conduction reaches the effect that well prevents with the shielding electromagnetic interference infiltration simultaneously; (2) the utility model has installed protecting cover additional, the convection current so that waterproof ventilated membrane can not scratched and breathe freely by foreign object; (3) the utility model adopts the standardization design that is threaded, installation method, and using scope is extensive.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is sectional structure chart of the present utility model;
