Abstract
The utility model discloses an integral waterproof instrument casing, which is applicable to integral waterproof instruments needing to be waterproof and dustproof and belongs to the field of electronic instruments and meters. The embedded integral waterproof instrument casing comprises a main casing and a front panel mounted at the front end of the main casing, the front panel is provided with a film panel tightly attached on the surface of the front panel, a sealing ring is mounted between the main casing and the front panel, a rear cover is mounted at the rear end of the main casing, a wire outlet hole is disposed between the main casing and the rear cover, an upper sealing strip and a lower sealing strip which seal a lead outlet portion of a circuit board component are mounted in the wire outlet hole, and the rear cover is embedded and clamped in the rear end of the main casing. The front surface of the casing can prevent sprayed water from optional directions, and the rear of the casing can effectively realize waterproofing by the aid of hermetic fastening between the rear cover and the main casing and sealing strips. The integral waterproof instrument casing has the advantages that the waterproof casing can increase protection level of instruments and meters, and is particularly suitable to be used under conditions of environments with higher waterproof and dustproof requirements.
Description
Technical field
The utility model relates to a kind of waterproof instrument, specifically is a kind of embedded integral waterproofing instrument housing.Be specially adapted to use under the demanding environment of waterproof and dustproof.
Background technology
Traditional flush type meter housing does not generally possess water-proof function, the rear portion of housing particularly, when instrument is used working environment in humidity, soft air in the environment is because cold and hot conversion and dewfall, form water droplet, when water droplet dropped onto on the instrument that does not possess water-proof function, water droplet was easy to just be penetrated into enclosure interior, cause whole instrument damage malfunctioning on the inner electronic devices and components thereby be dropped in, cause too early the scrapping of instrument.The product of scrapping too early increases the maintenance cost of using enterprise virtually, increases enterprise's production cost indirectly.
Summary of the invention
The purpose of this utility model is the above-mentioned deficiency that overcomes prior art, and a kind of integral waterproofing instrument housing is provided.
The utility model is with following technical scheme: a kind of embedded integral waterproofing instrument housing comprises main casing, is installed in the front panel on the main casing front end; Have on the plate in front be adjacent in its surface film face-plate; Between main casing and front panel, be equiped with O-ring seal; On the main casing rear end, bonnet is installed; Between main casing and bonnet, wire hole is arranged, last sealing strip and lower seal bar that the lead outlet with circuit board assemblies partly seals are installed in the wire hole; Described bonnet embeds and is clamped on the rear end of main casing.
Film face-plate on the front panel is used for sealing and shows and the button part; Embed main casing during the back cover installation, rely on the overlapping step of embedded part to form sealing, and by giving prominence to snap fit to main casing, the lead outlet of circuit board assemblies part is sealed by the upper-lower seal bar.After instrument embedded and is installed in cabinet or the instrument case, the faceplate part that is exposed on the external was by the O-ring seal water-tight between film face-plate and front panel and the main casing, and the positive front of housing can prevent the water spray of any direction; The sealing snapping of housing rear portion dependence bonnet and main casing and sealing strip be waterproof effectively.
The beneficial effects of the utility model are: this waterproof cover physical efficiency improves the degree of protection of instrument and meter, is particluarly suitable for the ambient conditions use down that waterproof and dustproof is had relatively high expectations.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model structural representation;
Fig. 2 is the housing outside drawing.
Among the figure: 1, film face-plate, 2, front panel, 3, O-ring seal, 4, circuit board assemblies, 5, main casing, 6, go up sealing strip, 7, the lower seal bar, 8, bonnet.
Embodiment
As depicted in figs. 1 and 2, embedded integral waterproofing instrument housing is made up of front panel 2, main casing 5, bonnet 8, film face-plate 1, O-ring seal 3, last sealing strip 6 and lower seal bar 7.Film face-plate 1 is adjacent in front on the plate 2, at main casing 5 and 2 installings of front panel O-ring seal 3; Bonnet 8 is installed on main casing 5 rear ends; Between main casing 5 and bonnet 8, wire hole is arranged, last sealing strip 6 and the lower seal bar 7 that line is added between is installed in the wire hole; Described bonnet 8 embeds and is clamped on the rear end of main casing 5.
The circuit board assemblies 4 of enclosure interior is placed on main casing 5 front panels 2 inner and that dependence snaps onto on the main casing and compresses, and film face-plate 1 is attached to demonstration and the button part that seals on the front panel 2 on the front panel 2; Embed main casing 5 when bonnet 8 is installed, rely on the overlapping step of embedded part to form sealing, and by two side-prominent snap fit to main casing 5, the lead outlet of circuit board assemblies part is sealed by last sealing strip 6 and lower seal bar 7.
Concrete method for making is: the gathering sill horizontal sliding of circuit board assemblies 4 from main casing 5 fronts along housing is in place, O-ring seal 3 is installed on the main casing 5, then front panel 2 is snapped on the main casing 5, front panel 2 compresses O-ring seal with main casing 5, pastes film face-plate 1 afterwards demonstration and button are partly sealed.Main casing 5 embeds the instrument installing plate from mounting hole, and relies on Elastic buckle to be fixed to installing plate, and bonnet 8 is inserted into the wire hole of main casing 5 back formation and uses sealing strip 6 and 7 sealings of lower seal bar, and bonnet and main casing rely on snap fit.
