Abstract
The utility model discloses a kind of rubber-insulated wire optical fiber heat-shrink tubes, and two locating bars just clamp covered wire cable both sides when welding, inner tube makes rectangle into control covered wire cable, so that will not arbitrarily be rotated after entering inner tube, covered wire cable enters in rubber-insulated wire optical fiber heat-shrink tube that two locating bars and covered wire cable fibre core are at sight alignment, and two locating bars just clamp covered wire cable fibre core after welding.The advantageous effects of the utility model：It solves in the production process of line pipe in the prior art, it is not parallel to be susceptible to two locating bars, and two locating bars are easy and together, locating bar cannot be grasped when welding in the position of covered wire cable, to which the disconnected fine rate after welding is very high, rubber-insulated wire fibre loss value can be increasing when use problem.
Description
Technical field
The utility model is related to optical communication field more particularly to a kind of rubber-insulated wire optical fiber heat-shrink tubes.
Background technology
With the arrival of information age, the usage amount of the optical fiber tube in optical communication field is in geometric increase, the prior art
(hereinafter referred to as outer tube) is through in heat-shrink tube using inner tube, 2 locating bars are worn in gap between the inner and outer pipe sections, but are produced
It is not parallel that it is susceptible to two locating bars in the process, and two locating bars are easy and together, when welding cannot grasp positioning
Stick is in the position of covered wire cable, and to which the disconnected fine rate after welding is very high, rubber-insulated wire fibre loss value can be increasing when use.
Utility model content
The purpose of this utility model is to provide a kind of inner tube rectangular rubber-insulated wire optical fiber heat-shrink tube, solves pipeline in the prior art
In the production process of pipe, it is not parallel to be susceptible to two locating bars, and two locating bars are easy and together, and when welding cannot
Locating bar is grasped in the position of covered wire cable, to which the disconnected fine rate after welding is very high, rubber-insulated wire fibre loss value can be more next when use
Bigger problem.
In order to solve the above technical problems, the utility model adopts the following technical solution：
A kind of rubber-insulated wire optical fiber heat-shrink tube of the utility model, including inner and outer tubes, the outer tube are designed as cylindrical structure, institute
Oblong barrel structure of the inner tube design with central rectangular aperture is stated, optical cable fibre core is placed in the central square hole, it is described interior
Pipe is arranged in the endoporus of the outer tube and is positioned by symmetrically arranged two locating bars.
Further, the locating bar is designed specifically to semicircle, the semicircular straight flange side and said inner tube
Straight flange fits, and the semicircular arc-shaped side side and the inner wall of the outer tube fit.
Further, uniform gap is remained between the optical cable fibre core and the rectangular opening of said inner tube before welding,
It eliminates to form seamless section in gap when welding between the outer tube, inner tube and locating bar.
Compared with prior art, the advantageous effects of the utility model：Solve the production of line pipe in the prior art
Cheng Zhong, it is not parallel to be susceptible to two locating bars, and two locating bars are easy and together, and when welding cannot grasp locating bar
In the position of covered wire cable, to which the disconnected fine rate after welding is very high, rubber-insulated wire fibre loss value can be increasing when use problem.
Description of the drawings
The utility model is described in further detail for explanation below in conjunction with the accompanying drawings.
Fig. 1 is the sectional view of the utility model rubber-insulated wire optical fiber heat-shrink tube
Reference sign：1, outer tube；2, inner tube；3, locating bar；4, covered wire cable fibre core；5, gap.
Specific implementation mode
As shown in Figure 1, a kind of rubber-insulated wire optical fiber heat-shrink tube comprising inner tube 2 and outer tube 1,3 both sides of said inner tube pass through positioning
Stick 3 is clamping inside outer tube 1, and said inner tube 2 is set as rectangle.
The application is put into semicircle positioning specifically, the shape of said inner tube 2 is changed to rectangle in two long side of rectangle
Stick 3, not only solves that be arranged two locating bars in the prior art not parallel, two locating bars be easy and together the problem of, and
And as shown in Figure 1, when welding, square is arranged in two locating bars 3 of the application setting just clamping covered wire cable both sides, the application
Shape inner tube 2 will not be rotated arbitrarily after effectivelying prevent covered wire cable to enter inner tube 2, and covered wire cable enters two in rubber-insulated wire optical fiber heat-shrink tube
At sight alignment, two locating bars 3 just clamp covered wire cable fibre core after welding, make this for locating bar 3 and covered wire cable fibre core 4
Fibre rate of breaking after product welding is zero, and welding rubber-insulated wire fibre loss value is zero.
Specifically, the locating bar 3 is designed specifically to semicircle, the semicircular straight flange side and said inner tube 2
Straight flange fits, and the semicircular arc-shaped side side and the inner wall of the outer tube fit.
Again specifically, remaining with uniform gap 5 between the optical cable fibre core 4 and the rectangular opening of said inner tube 2 before welding,
It eliminates to form seamless section in gap when welding between the outer tube 1, inner tube 2 and locating bar 3.
Embodiment described above is only that the preferred embodiment of the utility model is described, not to the utility model
Range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are new to this practicality
The various modifications and improvement that the technical solution of type is made should all fall into the protection domain of the utility model claims book determination
It is interior.
