Abstract
The utility model discloses an optical fiber hot melting protection casing. The optical fiber hot melting protection casing comprises a casing pipe and a casing cover; the casing pipe is provided with a casing pipe through hole; the casing cover is provided with a casing cover through hole communicated with the casing pipe through hole; two ends of the casing pipe are respectively provided with casing pipe threads; and an inner wall of the casing pipe is provided with casing cover threads cooperated with the casing pipe threads in a rotary manner. The optical fiber hot melting protection casing of the utility model is simple in structure, lower in production cost and maintenance cost, and convenient in installation; the casing pipe and the casing cover are cooperated so that a heat shrink tubing for connecting a heat melting point is effectively protected; the casing cover is arranged at two ends of the casing pipe in the rotary manner; and a clamping piece is pushed to tightly press an optical fiber cable, so that the purpose of fixing the cable is realized. In addition, the casing cover with a casing cover flange and the corresponding casing pipe can prevent the casing pipe from missing through buckling of the flange.
Description
Technical field
The utility model relates to communication network connection fittings technical field, is specifically related to optical fiber hot melt protective sleeve.
Background technology
At present, optical fiber technology development rapidly, FTTX fiber entering household is more and more universal, according to product needed, there will be two sections of optical fiber to carry out the operation of continued access, the method of its connection is that two sections of optical cable continued access ends are carried out to cold joint or hot melt connection, in prior art, optical fiber hot melt contact is that application heat-shrink tube is protected substantially, prevent because being exposed to that oxidation is caused in outside or because causing signal interference with other object contacts, and in actual applications, because heat-shrink tube outside does not have the protective devices such as protective cover, time one is of a specified duration, easily destroyed, thereby cause the destruction of optical fiber heat fusion joint, bring unnecessary loss and destruction.
Utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of optical fiber hot melt protective sleeve, can effectively to optical fiber heat fusion joint, protect, and simple in structure, low cost.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
Optical fiber hot melt protective sleeve, comprising: sleeve pipe and upper shield, and described sleeve pipe has sleeve through hole, and described upper shield has the upper shield through hole communicating with sleeve through hole; On the outer wall at described sleeve pipe two ends, be respectively arranged with casing threads, described upper shield inwall is provided with the upper shield screw thread coordinating with casing threads rotation; Described sleeve pipe both ends of the surface inwardly have a breach along casing length direction respectively, so that sleeve pipe two ends are all formed with two relative folders, described upper shield is less than the external diameter of two relative folders near the internal diameter at its place, outer face; The described sleeve pipe wherein free end of one end folder is provided with casing flange, and the inwall of corresponding described upper shield is provided with the upper shield flange being clasped with casing flange.
Described casing flange is active between upper shield flange and upper shield outer face.
The internal diameter of described sleeve pipe diminishes along its outer face direction gradually from casing flange.
The outer wall of described upper shield is provided with for anti-skidding groove.
Compared to existing technology; the beneficial effects of the utility model are: optical fiber hot melt protective sleeve of the present utility model is simple in structure; production cost and maintenance cost have been reduced; and easy for installation; by the cooperation of sleeve pipe and upper shield, the heat-shrink tube that protection is effectively connected heat fusion joint is installed; upper shield is installed on sleeve pipe two ends by the mode of rotation, and then promotes folder pressed fiber cable, plays the effect of fixed cable.In addition, the upper shield that has a upper shield flange can prevent the disappearance of upper shield with corresponding sleeve pipe by being clasped of flange.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is the section of structure of the utility model preferred embodiment.
Fig. 2 is the structural representation of the utility model preferred embodiment.
Embodiment
Be preferred embodiment of the present utility model as depicted in figs. 1 and 2, a kind of optical fiber hot melt protective sleeve, comprises sleeve pipe 1 and upper shield 4, and sleeve pipe 1 has sleeve through hole 10, and upper shield 4 has the upper shield through hole 7 communicating with sleeve pipe 1 through hole; On the outer wall at sleeve pipe 1 two ends, be respectively arranged with casing threads 2, upper shield 4 inwalls are provided with upper shield screw thread 5, and upper shield screw thread 5 is engage sleeves pipe thread 2 in rotary manner; Sleeve pipe 1 both ends of the surface inwardly have a breach along casing length direction respectively, so that sleeve pipe 1 two ends are all formed with two relative folders 6, upper shield 4 is less than the external diameter of folder 6 near the internal diameter at its place, outer face; The free end of one of them folder 6 is provided with casing flange 3, and the inwall of corresponding upper shield 4 is provided with the upper shield flange 9 being clasped with casing flange 3.
The internal diameter concrete structure of upper shield 4 is that the internal diameter of upper shield 4 reduces along its outer face direction gradually from upper shield flange 9.The upper shield 4 with casing flange 3 is inserted in after the folder 6 of sleeve pipe 1 correspondence, and casing flange 3 is active between upper shield flange 9 and upper shield 4 outer faces, can prevent that upper shield 4 is separated with sleeve pipe 1 and loses accessory.The outer wall of upper shield 4 is provided with for anti-skidding groove 8, and groove 8 is conducive to user and rotates upper shield 4.
The embodiment of this optical fiber hot melt protective sleeve is as follows: before two sections of optical fiber hot melts; sleeve pipe 1 is pierced into arbitrary section of optical fiber cable; upper shield 4 is pierced into respectively on two sections of optical fiber cables; after optical fiber hot melt, fusion point place is a heat-shrink tube, and sleeve pipe 1 is entangled to heat-shrink tube; upper shield 4 packs into the two ends of sleeve pipe 1; when upper shield 4 draws in to sleeve pipe 1 rotation, the bore that upper shield 4 inwalls reduce gradually makes folder 6 clamp to centre, and final folder 6 plays the effect of fixed fiber cable.
Above-mentioned embodiment is only preferred implementation of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
