Description
Technical field
Cable attachment apparatus field is the utility model is related to, specifically a kind of reducing thermoplastic assembled casing.
Background technology
Optical cable is because its message capacity is big, good confidentiality and the advantage such as adaptable are widely used in the fields such as communication.
In optical cable burial and construction, in embedded end or tapping point, optical cable need to pass ground and be connected or tap with end-equipment, to protect
Shield optical cable passes the safety of above ground portion, generally one section of steel pipe of outside suit in optical cable, and one layer of end can be also added in steel pipe
Head stretches out the soft protection pipe of steel pipe, to prevent cable surface directly contacts with port of steel pipe from causing friction damage.
This mounting means, can all there is space between steel pipe and soft protection pipe and soft protection pipe and optical cable, be
Rainwater, dust even toy is avoided to enter in space, during practice of construction, usually using mud or foam to space
Simply filled, however, after the regular hour, mud loses stickiness meeting nature and come off, and foam can also have aging
The phenomenon of contraction, cause the situation that space can reappear, it is necessary to be filled up again to space.
In addition, there is a method in which it is exactly that thermoplastic bushing is installed in the space port of optical cable and steel pipe, this sleeve pipe is protected
Shield effect is preferable, and not perishable, service life is also ideal, but this sleeve pipe is then helpless for existing optical cable,
Unless optical cable is removed, it is set with again, this cost is too big, loses more than gain；Secondly, after sleeve pipe aging, re-replace new
There is also this problem for sleeve pipe.
The content of the invention
To solve problems of the prior art, the utility model provides a kind of reducing thermoplastic assembled casing, that is, kept
The performance of existing sleeve pipe, also have and change the characteristics of convenient.
Concrete scheme of the present utility model is：A kind of reducing thermoplastic assembled casing, has a step body, the body by
Tube seat A and tube seat B matchings combine, and one end of the tube seat A and tube seat B is the less semicircular notch A of diameter, tube seat
A and tube seat the B other end are that the semicircular notch B being relatively large in diameter, notch A and notch B junction are provided with domatic transition face,
Graduation mark is equipped with tube seat A and tube seat B outer tube wall, the tube seat A and tube seat B are thermoplastic.
Body described in the utility model is mutually matched buckle by tube seat A and tube seat B and combined, wherein tube seat A both sides
Trough rim be neck, tube seat B both sides trough rim is the card convex to match with neck.
Body described in the utility model is mutually matched buckle by tube seat A and tube seat B and combined, tube seat A and tube seat B's
Side trough rim is neck, and tube seat A and tube seat B opposite side trough rim is the card convex with neck to matching.
Anticorrosive coat is scribbled on tube seat A and tube seat B described in the utility model outer tube wall.
Tube seat A and tube seat B described in the utility model thermoplastic are TPE or TPV materials.
Tube seat A and tube seat B described in the utility model pipe thickness are 1-2mm.
The inclination angle of tube seat A and tube seat B described in the utility model domatic transition face is 45-60 °.
The advantage that the utility model possesses is：
1st, traditional integral type sleeve pipe is split into and be assemblied to form by tube seat A and tube seat B buckles, solve integral type sleeve pipe
Existing aging change it is inconvenient and for existing optical cable it is not easy to install the problem of, simple operation, and greatly improve protection
The adaptability of sleeve pipe；
2nd, tube seat A and tube seat B uses thermoplastic material, and after being heated, nature adhesion sealing is carried out to wrappage, non-aging,
Service life is grown, good seal performance；One layer of anticorrosive coat is added in tube seat A and tube seat B outer walls simultaneously, is further extended using the longevity
Life；
3rd, graduation mark is set on tube seat A and tube seat B outer wall, can according to the length needs actually sealed, to tube seat A and
Tube seat B length is cut, simple and convenient, improves efficiency of construction；
4th, 45-60 ° will be arranged at tube seat A and tube seat B domatic transition face inclination angle, ensure that reflow process middle pipe
Smoothness is connected between groove A and tube seat B, avoids because angle causes greatly very much to heat the variation of rear enclosure tube shape, it also avoid because of angle
Degree is smaller, and domatic transition face is longer, influences the applicability of sleeve pipe.
