Abstract
The utility model discloses a plastic protection sleeve for a cable joint which acts a part in protecting the joint part of a buried cable. The utility model can be widely used in the communication (comprising electric power) engineering to replace an asphalt perfusion wooden box or the traditional works of asphalt jute winding, etc. The protection sleeve is made by thermoplastic molding of materials, such as polypropylene or nylon 6, etc. The joint opening adopts a plug-in type, the length of two butt jointed parts are equal, and the connection length of 40 mm guarantees the intensity of the interface and the regulating variable of the engineering. Protection sleeves with corresponding styles which are designed for cables with different forms are used for engineering construction directly.
Description
This sheath is the utility model that the buried cable blank area is shielded, and it can be widely used in communication (the containing electric power) engineering.
Home communications cable (containing power cable) often requires to adopt technologies such as pitch prill shrub box or the winding of pitch prill burlap after the soldering and sealing that continues.This method exists the field operation difficulty, carries difficulty and the problem of hindering the cable plastics core-spun yarn, becomes workmen's a burden.
According to the characteristics of reversed return type cable not, the design finished product plastic sheath is directly used in engineering, has overcome above-mentioned problem, has also improved project quality simultaneously.
The sheath shape is the identical pipe of internal diameter to two parts (removing interface) of inserting as shown in drawings, and two ends are bell mouth shape, and are whole like very symmetrical round prismatic.Adopting this shape, is consistent with the cable joint shape on the one hand, on the other hand can proof strength.Sheath wall thickness 4 millimeter can fully satisfy and bury the ground requirement for a long time.L3, L4 are the length of pipe part among the figure; L1, L2 are the length of horn shape part.φ 1, φ 2 are internal diameter sizes of sheath.Cited size in the form is the sheath reference data that is applicable to three kinds of lead sleeves.With four pipe small bore coaxial cables, 4 * 4 symmetries, long-distance telecommunication cables such as two pipe small bore coaxial cables are corresponding respectively.
This sheath adopts the manufacturing of material thermoplastics such as polypropylene or nylon 6.Have certain intensity and anticorrosion, characteristics such as the anti-plague of rats.
The sheath Interface design becomes plug-in, and promptly convenient working can guarantee the intensity of interface again.40 millimeters contain the spreading degree and have considered the practical adjustments amount in the engineering.Two parts equal in length of butt joint.Help Mold Making and production.
This sheath need give when using and pack into cable earlier, treat that cable splice, soldering and sealing operation are finished after, will insert the formula interface and plug together.No. 30 glue or the cable anticorrosive paint produced with the Ministry of Posts and Telecommunications at interface and with the position, slit of cable sheath cooperate plastic tape to seal, and reach the purpose of protecting cable joint.
According to Beijing signalman engineering unit probationary certificate, sheath is reasonable in design, and is easy to use, has certain advance, novelty at home.
Claims (2)
1, sheath is the plastic products that cable joint is partly shielded, and it is characterized in that:
A, mid portion (removing interface) are the pipes of internal diameter unanimity, and the two ends flare is whole like circle prismatic shape.
B, plug-in interface, maximum contain spreading degree 40 millimeter, wall thickness 4 millimeter.
2, according to the described sheath of claim 1, it is characterized in that L1 to L4, φ 1 φ 2 equidimensions all should match with cable lead sleeve and cable formula.
