Abstract
The utility model discloses a sealing structure of a miniature structure, which comprises a shell (1) and cover plates (2), wherein grooves (3) are formed on the wall around the shell (1), and lug bosses (4) are respectively arranged on the back sides of the cover plates (2) and in the positions corresponding to the grooves (3) and matched with the grooves (3). The sealing structure effectively solves the problem of the sealing of equipment, is a more unique sealing design technology, can be widely popularized in the design for the miniature electronic products and has a higher reference value for sealing design.
Description
Technical field
The utility model relates to the hermetically-sealed construction of a kind of Sealing Technology of small-scale structure, particularly a kind of small-scale structure.
Background technology
As the radio-frequency apparatus of armament systems nucleus equipment, a lot of unit for electrical property parameters are relatively more responsive to ambient parameter, so can not spray paint and wait three anti-processing in inside.If in storehouse, inner device and microwave substrate all will be subjected to the influence of environment to cause performance to occur changing with its long-term storage.In order to address this problem, must take seal approach to radio-frequency apparatus, guarantee inner environmental stability, thereby guarantee technical indicator, and make it possess three anti-characteristics of certain ability.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of hermetically-sealed construction of small-scale structure, thus the sealing of implementation structure, the service behaviour of assurance equipment.
For solving the problems of the technologies described above, the technical solution of the utility model: a kind of hermetically-sealed construction of small-scale structure, comprise housing, cover plate, be provided with groove on the wall around the described housing, reverse side and the corresponding position of groove at cover plate are provided with boss, and this boss and groove match.
In the hermetically-sealed construction of above-mentioned small-scale structure, in described groove, scribble adhesive.
The beneficial effects of the utility model: compared with prior art, the utility model equipment that makes has possessed the water-stop ability, through 130 ℃ of fluorocarbon oil leak detection checking sealings, and the examination of process humidity, mould and salt fog three anti-tests, affirmation equipment has possessed the water-stop ability.Take equipment that method of the present utility model produces through the extreme environment storage test in 8 years, the every electrical performance indexes of equipment meets design requirement.Hermetically-sealed construction of the present utility model makes the body of equipment possess the electromagnetic shielding sealing function, has reduced the leakage power of equipment, and the Electro Magnetic Compatibility that improves equipment is had a significant effect.The utility model efficiently solves the sealing problem of equipment, is a kind of comparatively unique Seal Design technology, can extensively be generalized in the design of miniaturization electronics product, has higher Seal Design reference value.
Description of drawings
Fig. 1 is the shell structure schematic diagram of equipment;
Fig. 2 is the covering plate structure schematic diagram of equipment.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
The specific embodiment
Embodiment 1.By the equipment that housing and two cover plates are formed, the principal element that generally influences its sealing has the sealing between housing and the two cover plates and the sealing of connector installation site.At the sealing of connector installation site, we have at first selected closed type connector (carrying sealing ring) for use, and in strict accordance with the bore size processing mounting groove of recommending on the components and parts handbook, guarantee the sealing of connector installation site.At the sealing between housing and the two cover plates, we mainly guarantee from structural design.As shown in Figure 1, 2, comprise housing 1, cover plate 2,, in groove 3, scribble adhesive being provided with groove 3 on the wall around the housing 1.Reverse side and groove 3 corresponding positions at cover plate 2 are provided with boss 4, and boss 4 matches with groove 3.During making, at first the wall around housing 1 (mills wide 1.6mm on the wall thickness 4 ~ 5mm), the groove 3 of dark 1mm, process wide 0.8mm at the reverse side of cover plate 2 again, the boss 4 of high 0.6mm, wide 1.6mm on this boss 4 and the housing 1, the groove 3 of dark 1mm matches, during general assembly equipment, recycle silicon rubber is coated with the groove 3 on the full housing 1, the glue amount is coated with full groove 3 for moderate, around wipeing off with blade again, with screw that cover plate 2 and housing 1 is fixing, during mounting screw, earlier screw is coated with silicon rubber, be screwed into again in the housing 1, dry the silicon rubber that overflows at last and get final product, thus the thorough seal of the equipment of assurance.
Embodiment of the present utility model is not limited to the foregoing description, all belongs within the protection domain of the present utility model in the various variations of making under the prerequisite that does not break away from the utility model aim.
Claims (2)
1. the hermetically-sealed construction of a small-scale structure, comprise housing (1), cover plate (2), it is characterized in that: be provided with groove (3) on the wall around the described housing (1), reverse side and the corresponding position of groove (3) at cover plate (2) are provided with boss (4), and boss (4) matches with groove (3).
2. the hermetically-sealed construction of small-scale structure according to claim 1 is characterized in that: scribble adhesive in described groove (3).
