Abstract
The utility model relates to a leather line fixer and a protective cover, which belong to a special protective device for a leather line joint in a network of a local telephone line. The utility model is characterized in that the leather line fixer and the protective cover are formed into a protective external member, the leather line fixer is an octagonal solid, four symmetrical line threading holes which are parallel to a side surface are arranged in the leather line fixer, and both ends of each of the line threading holes are provided with guiding angles, an oblong ling fixing hole is arranged in the protective cover, the middle part of the back part of the line fixing hole is provided with a partition board for separating the back part of the line fixing hole into two small holes and the end parts of the line fixing holes are provided with the guiding angles. The utility model can ensure the joints of a leather line can not be oxidated within fifty years without cracks, contacting resistance is not increased and various kinds of loss and inconvenience brought to users due to the obstacle of the joints of the leather line are reduced to the utmost extent. The utility model has the characteristics of simple structure, beautiful appearance, low cost and convenient operation and the utility model can be used for reducing the maintenance cost of the leather line and prolonging the service life of the leather line.
Description
Technical field
The utility model belongs to a kind of special protection setting of rubber-insulated wire joint in the local line network, particularly a kind of rubber-insulated wire solidus device and protective jacket.
Background technology
At present, there is a large amount of rubber-insulated wire joints in the domestic local line network, especially in the rural area, the average length of rubber-insulated wire is more than 100 meters, average each household will have plural rubber-insulated wire joint, along with the generally raising of people's living standard, the telephone subscriber in rural area grows with each passing day, and has therefore also increased telecommunications operation and maintenance work.The oxidation scission problem of rubber-insulated wire joint directly has influence on the communication quality and the obstacle cycle of subscriber phone, rubber-insulated wire joint autoxidation, and its life-span is 6～7 months.The processing mode of traditional rubber-insulated wire joint mainly contains two kinds, a kind of common mode is: two rubber-insulated wire heart yearn butt joints, put insulating sleeve more respectively, be wrapped with friction tape at last, this method exists: 1, the butt joint core is born rubber-insulated wire tension force, the butt joint core is in a single day oxidized, and mechanical strength weakens, and is easily broken by rubber-insulated wire tension force; 2, its complicated operation, difficulty are bigger, two respectively the heart yearn length of butt joint be difficult to guarantee to equate, occur the stressed phenomenon of single heart yearn easily, thereby easily broken.Another kind is in real work, and it is to adopt with rubber-insulated wire elder generation fast knot together that rubber-insulated wire joint more than 90% is arranged, and then the mode of twisting joint respectively, with adhesive plaster it is snarled, and all be to be directly exposed in the air but 70% joint is wherein arranged.The advantage of this method is simple to operation, and the heart yearn of twisting joint is not born rubber-insulated wire tension force, easy fracture not before the heart yearn oxidation; Its shortcoming is that the copper covered steel heart yearn is easily oxidized, especially do not twine adhesive plaster, be directly exposed to the general life-span of airborne joint all about 6～7 months, twine adhesive plaster and extorted the good joint life-span about 1 year, infiltered rainwater if extort bad the inside, form life-span that the aqueous solution will shortening joint only 3～4 months joints will oxidize away, this also is the reason that a lot of joints do not twine adhesive plaster.Joint is in a single day oxidized in addition, and then the contact resistance of joint will increase greatly, can influence and send sound quality, forms noise, and the joint severe oxidation that has also can occur off and on, obstacle such as can advance to go out.
Summary of the invention
The utility model has overcome the defective of above-mentioned existence, and purpose is special joint protection setting---rubber-insulated wire solidus device and the protective jacket of guaranteeing the not oxidation in 15 years of rubber-insulated wire joint for telecom operators provide a kind of, not rupturing, do not increase contact resistance.
The utility model rubber-insulated wire solidus device and protective jacket content Description:
The utility model rubber-insulated wire solidus device and protective jacket, it is characterized in that: the protection external member of forming by rubber-insulated wire solidus device and protective jacket, rubber-insulated wire solidus device is one eight a prismatic entity, and portion is provided with the through wires hole of four symmetries and parallel and side within it, and the two ends of through wires hole have lead angle; The inside of protective jacket is a rectangular solidus hole, and the place has a division board that the rear portion in solidus hole is divided into 2 apertures in the middle of the rear portion in solidus hole, has lead angle in the end in solidus hole.
The utility model rubber-insulated wire solidus device and protective jacket can be guaranteed the not oxidation within 15 years of rubber-insulated wire joint, not rupture, contact resistance do not increase, thereby reduced various losses and the inconvenience that causes to the user because of rubber-insulated wire joint obstacle to greatest extent.The utlity model has characteristics simple in structure, handsome in appearance, with low cost, easy to use, employing the utility model can reduce the maintenance cost of rubber-insulated wire, the useful life of having improved rubber-insulated wire greatly.

Fig. 3 is the protective jacket structure chart
Among the figure: 1 is that rubber-insulated wire solidus device, 2 is that protective jacket, 3 is that through wires hole, 4 is that lead angle, 5 is that solidus hole, 6 is that division board, 7 is a lead angle.
Embodiment
The utility model rubber-insulated wire solidus device and protective jacket are achieved in that below in conjunction with accompanying drawing and specify.See Fig. 1, the protection external member that the utility model is made up of rubber-insulated wire solidus device 1 and protective jacket 2.See Fig. 2, rubber-insulated wire solidus device 1 is one eight a prismatic entity, and portion is provided with through wires hole 3 four symmetries and that be parallel to the side within it, and threading has lead angle 4 at the two ends of through wires hole 3 for convenience.See Fig. 3, the inside of protective jacket 4 is rectangular solidus holes 5, and the place has a division board 6 that the rear portion in solidus hole 5 is divided into 2 apertures in the middle of the rear portion in solidus hole 5, has lead angle 7 in the end in solidus hole 5.
Rubber-insulated wire solidus device 1 and protective jacket 2 adopt high-quality PVC to make, and rubber-insulated wire is penetrated by through wires hole 3 from the two ends of rubber-insulated wire solidus device 1 respectively when wiring, turns back to pass from corresponding through wires hole 3 again, make it reach stable in rubber-insulated wire solidus device 1 and connect.Then the heart yearn of rubber-insulated wire joint is removed the peel, twisted joint respectively, heart yearn after will twisting joint again immerses fully in conjunction with in the glue, directly be inserted into after the taking-up in the rectangle solidus hole 5 of protective jacket 2 inside, treating after the glue curing that protective jacket 2 and rubber-insulated wire are molten is one, there is not pore, fundamentally guaranteed the not oxidated and corrosion of the heart yearn of twisting joint, made circuit have good electrical communications characteristic.
