Description
Technical field
The utility model relates to a kind of cabinet, specifically a kind of waterproof shielding ATR cabinet.
Background technology
Along with electronic equipment requires progressively to improve to environment for use, its cabinet also improves waterproof (rainproof) and electromagnetic compatibility requirements thereupon.Particularly for the cabinet of ATR standard, because it often is used in the relative ten minutes rugged environment, therefore the requirement to waterproof and electromagnetic shielding also compares higher.In current military products industry, what adopt basically is to fill the water proof rubber sealing ring between cabinet cover plate and body and panel and housing, materials such as the conduction solid rubber bar of " O " type, " D " type, rectangle or rubber slab, even the material of the satisfied two kinds of difference in functionalitys of the employing that has is isolated the mode of installing respectively mutually, through facts have proved, more than the mounting means of various materials or separation always be difficult to make waterproof, electromagnetic shielding to reach effect preferably simultaneously, reliability is relatively poor.For above-mentioned encapsulant, in waterproof and shielding, always exist contradiction, the conductive particle that adds in the encapsulant is many more, and electric conductivity is good more, but the hardness of material can increase thereupon.And the hardness of encapsulant directly influences the effect of water-stop, and within the specific limits, hardness is big more, and watertightness is poor more, and the screw pretightning force that needs is big more.Tightly or in use do not become flexible if screw is twisted, tend to cause the failure of waterproof.For solving the contradiction between the waterproof shielding, the utility model provides effective solution from aspects such as casing structure, encapsulants.Sealing strip often is installed in " U " type groove, and sealing strip does not use conductive adhesive to tend in use come off, easier coming off when particularly being contained on vertical plane or the part base plane.Solution in the past: have plenty of and add common gum, but can influence conductivity; Have plenty of the employing conductive adhesive, but price is too high, is not easy to maintenance.
Summary of the invention
In order to overcome the weak point in the above background technology, it is a kind of simple in structure that the utility model provides, a kind of waterproof shielding of energy with low cost ATR cabinet.
A kind of waterproof shielding ATR cabinet of the present utility model is realized in the following manner, the structure of this cabinet comprises housing, panel, upper cover plate and lower cover, panel is arranged on the housing front end face, upper cover plate is arranged on the top of housing, lower cover is arranged on the bottom of housing, fix by holding screw between upper cover plate and the case top, fix by sunk screw between lower cover and the housing bottom, the nut lower surface of holding screw is provided with groove and matches with the boss of upper cover plate top setting, is provided with the flexiplast liner between groove and the boss; Be respectively arranged with dovetail groove on position that upper cover plate, lower cover are connected with housing and the housing front end face, be provided with the double-peak type sealing strip in the dovetail groove.
Junction between housing, panel and the upper cover plate is " protruding " type, and the bottom surface of upper cover plate is for falling " recessed " shape and match with housing, panel, and upper cover plate is buckled in case top; Junction between housing, panel and the lower cover is down " recessed " type, and lower cover is embedded in housing bottom.
The double-peak type sealing strip is made up of watertight composition and screen, and its cross sectional shape is " B " type or " D " type; Waterproof layer material is a water-proof silica-gel, and polymeric barrier layer materials is an electric silica gel.
Double-peak type sealing strip inside is provided with the hollow cavity, and hollow cavity cross-section shape is " D " type or " O " type.
The beneficial effects of the utility model are:
(1) adopting inside is the bimodal sealing strip of hollow, can make it reach best waterproof and effectiveness simultaneously by regulating the hollow cavity size, and reliability improves greatly;
(2) sealing strip has adopted the compound of common silica gel and electric silica gel, and two kinds of materials all pass through effectively to reduce simultaneously, have reduced the cost (cost of electric silica gel is far longer than the cost of common silica gel) of material;
(3) form that sealing strip adopts dovetail groove is installed, need not be special bonding, assembling is simple, is easy to change, and has saved the cost of electric conducting material simultaneously.
(4) between cover plate, panel and the housing, the mounting means of " labyrinth type " between screw and the housing forms the double protection system with bimodal sealing strip to casing, has guaranteed the reliability of waterproof and electromagnetic compatibility more up and down.
