The multifunctional room infrared optical fiber distributes protective housing
Technical field
The utility model belongs to distributing cabinet, refers to especially a kind of open-air multifunctional room infrared optical fiber distribution protective housing that arranges and higher dustproof and waterproof requirement is arranged that is suitable for.
Background technology
In present existing optical fiber dispensing apparatus, optical cable mainly distributes by GPZ, concrete structure is, after optical cable enters GPZ, through melting fine dish wiring, melt fine the distribution, then connect the miscellaneous equipment that outputs to the repeater after optical fiber by GPZ by flange.GPZ generally adopts metal shell, easily corrosion.The box body inner chamber is less, the limited amount of receiving optical fiber.Be the hard contact that coordinates between the box body joint portion of GPZ, sealing property (water proof and dust proof effect) is poor, the connection between parts not firm (shell comes off, GPZ and tail optical fiber easily get loose).
Summary of the invention
The purpose of this utility model is to provide a kind of multifunctional room infrared optical fiber with better water proof and dust proof performance to distribute protective housing.
Overall technical architecture of the present utility model is:
The multifunctional room infrared optical fiber distributes protective housing, comprises by the upper cover that rotates assembling, lower cover fastening the box body that forms, and is opened in cable import and outlet on box body, is arranged at the fine dish that melts in box body; The joint portion at the fastening edge of described upper cover, lower cover is provided with the hermetically-sealed construction that is comprised of adaptive strip bulge and strip groove, is embedded with O-ring seal in strip groove, and the cable inlet and outlet is provided with the containment member adaptive with the cable external diameter.
Can it is evident that, cable import and outlet can be adopted the shutoff sealing that blocks water under non-working condition, because the shutoff that blocks water belongs to existing standard spare, no longer its 26S Proteasome Structure and Function is given unnecessary details at this.
Concrete technical construction of the present utility model also has:
The Main Function of containment member is the sealing problem that solves between cable and cable import and outlet; can adopt the various structures form; special joint for example; O-ring seal or sealing gasket etc.; all do not break away from protection category of the present utility model, wherein comparatively common and preferred technical scheme is, containment member is Waterproof connector of cable; because Waterproof connector of cable is prior art, do not repeat them here.
For guaranteeing the sealing of box body, described upper cover and lower cover are by connecting the securing member wringing fit.Connecting securing member can adopt and comprise the various structures forms such as buckle, lockset, web member cross-under be fixing, wherein comparatively preferred and common technical scheme is, described connection securing member comprise correspondence be located at upper cover and under the mount pad that covers, and be connected in clamp structure between mount pad.More preferred technical scheme is that described clamp structure is selected holding screw.
Fix for the distribution of optical fiber after satisfied molten fibre reaches, be preferred embodiment, be provided with installing plate in lower cover, installing plate and lower cover inwall are fixed by connecting elements, and the installing plate spaced surface is distributed with mounting hole.
Preferably the set-up mode of installing plate is, in described installing plate one side and lower cover, corresponding sidewall adopts bearing pin to rotate assembling, and the installing plate opposite side is fixed in lower cover by the column level.Installing plate can be fixed by fixed screw, column and lower cover like this; after the screw that gets loose; can rotate assembling along bearing pin and lower cover; be convenient to like this be arranged in lower cover melting fine dish and other multiple standards part; can it is evident that; can add according to actual needs in lower cover and supporting holder of existing standard spare etc., all not break away from protection category of the present utility model.
The obtained technical progress of the utility model is:
The utility model by being provided with waterproof between upper and lower covers hermetically-sealed construction and the technological means such as cable connector of waterproof, solved the poor problem of cable distributor disk sealing effectiveness, its installation is simple and convenient, the employing of installing plate, make the cable that melts after fibre be easy to arrange, also can be suitable for simultaneously other and use for the small-sized field detection equipment that anhydrous dustfree environment has higher requirements.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further described; but conduct is not to restriction of the present utility model; protection domain of the present utility model is as the criterion with the content of claim record; any equivalence techniques means of making according to instructions are replaced, and all do not break away from protection domain of the present utility model.
The unitary construction of the present embodiment comprises by the upper cover 1 that rotates assembling, lower cover 3 fastening the box body that forms as shown, is opened in cable import and outlet on box body, is arranged at the fine dish that melts in box body; The joint portion at the fastening edge of described upper cover 1, lower cover 3 is provided with the hermetically-sealed construction that is comprised of adaptive strip bulge and strip groove, is embedded with O-ring seal 8 in strip groove, and the cable inlet and outlet is provided with the containment member 5 adaptive with the cable external diameter.
Containment member 5 is Waterproof connector of cable, because Waterproof connector of cable is prior art, does not repeat them here.
Described upper cover 1 and lower cover 3 are by connecting the securing member wringing fit.Described connection securing member comprises that correspondence is located at the mount pad 4 on upper cover 1 and lower cover 3, and is connected in the clamp structure between mount pad 4.More preferred technical scheme is that described clamp structure is selected holding screw.
Be provided with installing plate 2 in lower cover 3, installing plate 2 is fixed by connecting elements with lower cover 3 inwalls, and installing plate 2 spaced surfaces are distributed with mounting hole 6.
Described installing plate 2 one sides adopt bearing pin to rotate assembling with the interior corresponding sidewall of lower cover 3, and installing plate 2 opposite sides are fixed in lower cover 3 by column 7 levels.
