Jumping fiber is strengthened in shaping protectionTechnical field
The utility model relates to a kind of jumping fiber, relates in particular to a kind of shaping protection and strengthens jumping fiber.
Background technology
As the important component part of intelligent grid; the construction of intelligent substation just advances at Fast Construction; jumping fiber is as the important component part of intelligent substation optical-fibre channel; purposes is very extensive; not only for the connection between the each equipment of intelligent substation communication network, and be directly used in being connected between each intelligent assembly in transformer station process layer network (as: intelligent terminal, merge cells, protective device, metering outfit etc.) and optical cable branch box.Jumping fiber is widely used in intelligent substation, jointly formed the main thoroughfare of intelligent substation information interaction with the optical communication equipment such as optical cable, switch, therefore jumping fiber installation quality and operational reliability have become the important factor in order of intelligent substation and even electric power netting safe running.
Jumping fiber, also referred to as double end tail optical fiber, refers to that two ends are all with the optical fiber of metal connector plug, for light path jumper connection.Owing to forming the feature of jumping fiber material self, physical strength and the safeguard procedures of tradition jumping fiber can not meet intelligent substation and the operation of power networks requirement to its security, special in also lacking necessary fiber plant mounting process specification at present, the jumping fiber of quite a few intelligent substation is installed substantially all according to the mounting process of electric wire (distribution in cabinet), adopt multiply colligation or bending to put into the installation method of wire way box, both cannot realize effective isolation of optical fiber and electric wire, increase and safeguard and the difficulty of changing, easily cause again jumping fiber crooked process radius too small, affect the communication quality of optical-fibre channel, even cause the damage of jumping fiber irrecoverability.
Utility model content
The purpose of this utility model is to provide a kind of shaping protection and strengthens jumping fiber, can either realize effective isolation of optical fiber and electric wire, can avoid again jumping fiber because bending causes damage, improves the communication quality of optical-fibre channel.
The utility model adopts following technical proposals:
Jumping fiber is strengthened in a kind of shaping protection, comprise that two ends are provided with the optical fiber of metal connector plug, also comprise web member and metal sizing flexible pipe, the two ends of web member are connected with metal connector plug and metal sizing flexible pipe respectively, and optical fiber is arranged in metal sizing flexible pipe inner chamber.
On described metal connector plug, be provided with external thread, one end of web member is provided with the internal thread coordinating with external thread, the other end of web member is provided with ring groove, in ring groove, be arranged with locating ring, on locating ring, be along the circumferential direction evenly provided with multiple " location claws of [" shape, " the location claw of [" shape is followed successively by clamping section, interlude and canned paragraph from top to bottom, and clamping section and canned paragraph extend internally; Described metal sizing hose end is fixedly connected with locating sleeve, and locating sleeve surface is provided with guiding groove, and the end of guiding groove is provided with pilot hole.
The clamping section of described location claw and interlude, interlude and canned paragraph are 60 ° of angle settings, and pilot hole and the locating sleeve surface of the guiding groove end setting of locating sleeve surface are also 60 ° of angle settings.
The utility model utilizes web member connection metal connector plug and metal sizing flexible pipe respectively, fiber section in jumping fiber is arranged among metal sizing flexible pipe internal cavities, can in solid space, bend to arbitrarily definite shape and keep, when bending, length and size are basicly stable, bending rear hose itself has certain anchorage force and has good plasticity, can prevent the too small shape of radius bend and affect devices communicating, realize effective isolation of optical fiber and electric wire, can avoid again jumping fiber because bending causes damage, improve the communication quality of optical-fibre channel.

Embodiment
As shown in Figures 1 to 4, the utility model comprises that two ends are provided with the optical fiber 2 of metal connector plug 1, web member 3 and metal sizing flexible pipe 4, the two ends of web member 3 are connected with metal connector plug 1 and metal sizing flexible pipe 4 respectively, and optical fiber 2 is arranged in metal sizing flexible pipe 4 inner chambers.Metal sizing flexible pipe 4 is to curl up the coated composite metal pipe forming by metal spring steel wire and galvanized iron wire or other metal wire rods, hollow has spiral lamination outward, optical fiber 2 is through in metal sizing flexible pipe 4, make the utility model can in solid space, bend to arbitrarily definite shape and keep, when bending, length and size are basicly stable, bending rear hose itself has certain anchorage force and has good plasticity, can prevent the too small shape of radius bend and affect devices communicating, reduce the probability that traditional jumping fiber overflexing causes attenuation passage to increase.
On the metal connector plug 1 at optical fiber 2 two ends, be provided with external thread 5, one end of web member 3 is provided with the internal thread 6 coordinating with external thread 5, and web member 3 is threaded connection with metal connector plug 1; The other end of web member 3 is provided with ring groove, in ring groove, be arranged with locating ring 7, on locating ring 7, be along the circumferential direction evenly provided with multiple " location claws 8 of [" shape, " the location claw 8 of [" shape is followed successively by clamping section 8-1, interlude 8-2 and canned paragraph 8-3 from top to bottom, and clamping section 8-1 and canned paragraph 8-3 extend internally; Metal sizing flexible pipe 4 ends are fixedly connected with locating sleeve 9, and locating sleeve 9 surfaces are provided with guiding groove 10, and the end of guiding groove 10 is provided with pilot hole 11.The position of guiding groove 10 and quantity and location claw 8 match.
In order further to ensure the connective stability of web member 3 and metal sizing flexible pipe 4, the clamping section 8-1 of described location claw 8 and interlude 8-2, interlude 8-2 and canned paragraph 8-3 are 60 ° of angle settings, and the pilot hole 11 of the surperficial guiding groove 10 end settings of locating sleeve 9 is also 60 ° of angle settings with locating sleeve 9 surfaces.
In the time that web member 3 is connected with metal sizing flexible pipe 4 end locating sleeves 9, each location claw 8 is aimed to corresponding guiding groove 10, then make web member 3 and metal sizing flexible pipe 4 end move toward one another, in the time that the clamping section 8-1 of location claw 8 arrives pilot hole 11, under the elastic reaction of location claw 8, will insert in pilot hole 11, play fixation.Meanwhile, because locating ring 7 and locating sleeve 9 can relatively rotate, in the time having External Force Acting to cause metal sizing flexible pipe 4 to rotate, can not cause the rotation of the optical fiber 2 of metal sizing flexible pipe 4 inside, can avoid the damage of optical fiber 2.
