Abstract
The invention discloses a sheet molding compound (SMC) optical cable fiber distributing box which comprises a box body. Arc wire-wrap boards are arranged in the box body in pairs. The arc wire-wrap boards comprise sleeves and plug sticks. The plug sticks are inserted into the sleeves in an arranged mode. Sliding grooves are arranged in the box body and the arc wire-wrap boards are arranged in the sliding grooves in a sliding mode. Fixed grooves matched with the plug sticks are arranged behind the sliding grooves in the box body. The plug sticks enter into the fixed grooves through the sleeves. The sheet molding compound optical cable fiber distributing box can ensure that a cable coil can be tightly wound on a coil disc so that a too small bent radius of an optical cable does not occur and signal transmission quality is ensured.
Description
Technical field
The present invention relates to communication equipment field, more specifically, relate to a kind of optical cable fiber-dividing box.
Background technology
Optical cable fiber-dividing box is the visual plant during fiber optic network is built, and can be used for main cable and the welding of branched cable phase, and the covered wire cable that will enter indoor many of user is integrated afterwards and is communicated with the main cable welding.
Conventional cable fiber-dividing box structure such as license notification number are a kind of fiber-dividing box of the Chinese disclosure of the invention of CN 202472080 U, mainly comprise square casing, casing top is coupled case lid, at the bottom of the one side that casing and case lid face is case, is the sidewall of casing between at the bottom of case lid and case.Be provided with at the middle part of a sidewall of casing and cross cable device for what main cable was passed, press close to this place side-walls and have the optical cable fixing device corresponding with crossing cable device in casing, fix for the main cable that will pass cable device.Be fixed with fusion splicing devices at casing middle part, it is used for main cable and tail optical fiber welding, and the distributed arc-shape winding plate of paired setting of the both sides, front and back of fusion splicing devices is for being wound around unnecessary tail optical fiber.Requirement for the arc-shape winding plate is that the radius of arc-shape winding plate 1 is greater than the minimum radius bend of tail optical fiber.See that (in Fig. 3, dotted line represents optical fiber to Fig. 3, optical fiber is actual has a lot of bundles) problem that easily occurs is, general all by manually optical fiber 2 being wound on paired arc coiling plate 1, optical fiber and arc-shape winding plate 1 are difficult to reach fit closely (meeting is just like the deviation of d displacement in Fig. 3), the coiling weak effect, cause the actual crooked process radius of optical fiber less than theoretical crooked process radius, affected signal transmission effect.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of optical cable fiber-dividing box of SMC material, guaranteed can fit when optical cable is wound in wire spool closely, thereby guaranteed that optical fiber does not have too small crooked process radius, guaranteed signal transmission quality.
The present invention is achieved through the following technical solutions: a kind of optical cable fiber-dividing box of SMC material, comprise casing, the arc-shape winding plate is set in described casing in pairs, described arc-shape winding plate comprises sleeve and stopper rod, described stopper rod is inserted in described sleeve, on described casing, chute is set, and described arc-shape winding plate slides and is arranged in chute, be positioned at the chute rear side at casing and be provided with the pickup groove that coordinates with described stopper rod, described stopper rod enters pickup groove by sleeve.
In technique scheme, in described sleeve, spring is set, described spring one end leans stopper rod, and the described spring other end leans sleeve lining.
In technique scheme, on the outer wall of described stopper rod, draw ring is set.
The present invention has following beneficial effect: the present invention has guaranteed can fit when optical cable is wound in wire spool closely, thereby has guaranteed that optical fiber does not have too small crooked process radius, has guaranteed signal transmission quality.
Description of drawings
Fig. 1 is the schematic diagram of optical fibre winding in background technology.
Fig. 2 is structural representation of the present invention.
Fig. 3 is the cross-sectional schematic that arc-shape winding plate of the present invention coordinates with casing.
Fig. 4 is the structural representation of gripping mechanism of the present invention.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail: referring to Fig. 1 to Fig. 4, a kind of optical cable fiber-dividing box of SMC material, comprise casing 2, described tank material adopts the SMC material to make, have excellent electrical insulation capability, mechanical property, thermal stability, chemically-resistant anti-corrosive properties, make casing can reach more than 20 years serviceable life.
In described casing 2, arc-shape winding plate 1 is set in pairs, described arc-shape winding plate 1 comprises sleeve 10 and stopper rod 11, draw ring 13 is set on the outer wall of described stopper rod 11, center of effort is provided when being convenient to pull stopper rod 11, described stopper rod 11 is inserted in sleeve 10, in described sleeve 10, spring 12 is set, described spring 12 1 ends lean stopper rod 11, and the described spring other end 12 leans sleeve 10 inwalls.
On described casing 2, chute 3 is set, described arc-shape winding plate 1 slides and is arranged in chute 3, is positioned at casing the pickup groove 20 that chute 3 rear side settings coordinate with described stopper rod 11, and described stopper rod 41 enters pickup groove 20 by sleeve 10.
When needing coiling, at first pull the draw ring 13 on stopper rod 11, pull out stopper rod 11, make stopper rod 11 break away from pickup groove 20, this moment, the down sliding sleeve 10, make sleeve reorientate in the pickup groove of downside, then begin coiling, after coiling is completed, pull out stopper rod 11, upward sliding sleeve 10, after optical fiber was tightened, unclamping stopper rod 11, to make stopper rod 11 enter in the upside pickup groove spacing.Therefore guaranteed that optical fiber and arc-shape winding plate can fit closely, wound the line effective, guaranteed to cause the actual crooked process radius of optical fiber can equal theoretical crooked process radius, so signal transmission effect has been better.
Be provided with optical cable gripping mechanism 4 in described casing 2, described optical cable gripping mechanism 4 comprises guide pin bushing 40, and sliding in described guide pin bushing arranges compressing tablet 41, and described compressing tablet 41 is rotationally connected in a screw rod 42, in described guide pin bushing 40 upper surfaces, threaded hole is set, described screw rod 42 is twisted and is located in described threaded hole.Arrange in described screw rod 42 ends and twist cap 43.When optical cable penetrated casing, at first by described gripping mechanism 4, by turning screw rod 42 downwards, screw rod 42 drove compressing tablet 41 and presses down, to being fixed by the optical cable in gripping mechanism 4.
