According to the optical fiber microtube with the spiral stainless steel protective sleeve, a spiral stainless steel protective sleeve is added in the existing outer sheath of the optical fiber microtube, thereby facilitating the rolling and storage of the microtube, maintaining good application effect of the optical fiber microtube, and ensuring the reliability of communication.
Description
Technical field
The utility model relates to a kind of optical fiber microtubule with spirality stainless steel protection cover, belongs to the communication facilities technical field.
Background technology
Communication pipe is built as strategy-driven investment, and annual input amount is very big, and along with city Xincheng District, the quickening of development area construction and the increasing of old town road reformation dynamics, the investment of communication pipe is more and more big, the trend of not slowing down.Premier Wen Jiabao's the government work report proposes, and development generation information technology is strengthened the network infrastructure construction, promotes the integration of three networks and makes substantial progress.Ministry of Industry and Information has carried out comprehensive planning with regard to the broadband construction in 12 periods, plans 2015, and broadband, city speed will reach 20M, and the broadband speed in rural area will rise to 4M, and provinces and cities with good conditionsi broadband speed will be higher.
Flourish along with the communications industry continues to increase for the demand of optical fiber with microtubule, makes microtubule that vast potential for future development arranged.Optical fiber is a novel operating type with going into, has saved aboveground space greatly, combines no-excavation construction method again, has avoided the destruction of pipeline laying to town road, and easy construction is quick.
In existing technology; The optical fiber communication protection tube generally all is the high density polyethylene microtubule, and this microtubule skin is a high density polyethylene, is shaped on several equally distributed axially directed grooves in the pipe; And on inside pipe wall the compound silicrete that contains silicone oil and monox, i.e. silicon core fibre microtubule.During use, mini optical fibre is threaded onto in the pipe.Owing to be rich in silicrete in the pipe, and be provided with direction recess in the pipe, the feasible mini optical fibre frictional resistance that installs is little, time saving and energy saving, easy to use.
But, in the work progress of communication pipe, can inevitably to employ some plant equipment, run into the communication pipe that has laid with metallic weapon because of carelessness sometimes, cause the damage of communication pipe internal optical fiber.In addition, moist also can cause pipeline to damage with extraneous factors such as mouse bite, so the inner optical fiber of damage, the reliability that influence is communicated by letter.
Summary of the invention
The purpose of the utility model is to propose a kind of optical fiber microtubule with spirality stainless steel protection cover, changes the structure of existing optical fiber microtubule, with the safe handling of assurance communication pipe, thereby guarantees the reliable of communication.
The optical fiber microtubule of the band spirality stainless steel protection cover that the utility model proposes is made up of high density polyethylene optical fiber microtubule, spirality stainless steel protection cover and high density polyethylene oversheath; Described high density polyethylene optical fiber microtubule is in the center of optical fiber microtubule; Described spirality stainless steel protection cover twines the outside that is wrapped in high density polyethylene optical fiber microtubule, and described high density polyethylene oversheath is wrapped in the outside of spirality stainless steel protection cover.
Above-mentioned optical fiber microtubule, spirality stainless steel sheath wherein is a spirality, closely is wrapped in the skin of high density polyethylene optical fiber microtubule.
Above-mentioned optical fiber microtubule, high density polyethylene oversheath wherein use the skin of bonding agent close adhesion at spiral stainless steel protection cover.
The optical fiber microtubule of the band spirality stainless steel protection cover that the utility model proposes has added one deck spirality stainless steel protection cover in the outside of existing high density polyethylene optical fiber microtubule, be convenient to the rolling of microtubule and deposit; Because the common rolling of microtubule is to treucher; Must be crooked, with stainless steel protection Analysis of Nested Design spirality, be convenient to the optical fiber microtubule on take inventory and put; To avoid straight stainless steel undesirable, on the contrary interior cables is played damage effect because of its pliability and flexibility; Outside at spirality stainless steel protection cover has added a hdpe layer sheath, in order to protection spirality stainless steel layer.And the optical fiber microtubule of the utility model proposition, production technology is simple, and common materials just can satisfy its requirement.Adopt stainless protection layer; Can only not prevent the careless sliding trackle microtubule of metallic weapon; Influence the use of optical fiber; And can also detect the accurate position of microtubule with detection instrument, and high density polyethylene optical fiber microtubule in the market can not detect with detection instrument, so in work progress, be damaged easily.Add after the stainless protection layer, can detect the accurate position of microtubule, directly avoid the destruction of metallic weapon with detection instrument.Even outer hdpe layer sheath is destroyed, also can keep the good result of use of optical fiber microtubule, guaranteed the reliability of communication.
