Description
Technical field
It the utility model is related to a kind of electric power saver sub, and in particular to a kind of electric power cable poling wiring is connect with protection
Head.
Background technology
Cable is placed in the insulated conductor formed in sealing sheath by the conducting wire center of one or more mutually insulated.Can outside it
Add protection coating, for transmitting, distributing electric energy or transmission electric signal.Its difference with common wiring be mainly cable dimension compared with
Greatly, structure is more complicated.Cable is mainly made up of following 4 part.1. conducting wire center：It is made of high conductivity material (copper or aluminium).
According to requirement of the laying use condition to cable softness, every line heart may it is twisted by solid conductor or multiple conducting wires and
Into.2. insulating barrier：Insulating materials as cable should have high insulaion resistance, high breakdown field strength, low medium
Loss and low dielectric constant.The insulating materials commonly used in cable has oil-paper, polyvinyl chloride, polyethylene, crosslinked polyethylene, rubber
Skin etc..Cable is often classified with insulating materials, such as oil-impregnated paper insulation cable, polyvinyl chloride cable, twisted polyethylene cable etc..③
Sealing sheath：Protect protection insulated wire heart from the damage of machinery, moisture, moisture, chemical substance, light etc..Insulation for moisture-sensitive,
Typically use lead or aluminium extrusion sealing sheath.4. protect coating：To protect sealing sheath from mechanical damage.It is general to use
Galvanized steel strip, steel wire or copper strips, copper wire etc. surround outside sheath (title armored cable) as armor, and armor plays electric field screen simultaneously
Cover and prevent the effect of external electromagnetic wave interference.In order to avoid steel band, steel wire are corroded by surrounding media, typically outside them
Pitch or wrapping macerated jute layer or extruded polyethylene, polyvinyl chloride set.
1832, tsarist Russia's army officers were permitted woods lattice and telegraphy line are embedded in into underground, exhausted with rubber each other between six conductors
With being placed in glass tube after edge, here it is an earliest in the world buried cable.By the conduction of one or more mutually insulated
The line heart is placed in the insulated conductor formed in sealing sheath.Protection coating can be added outside it, for transmitting, distributing electric energy or transmission electricity
Signal.The difference of it and common wiring is mainly that cable dimension is larger, and structure is more complicated.Compared with overhead line, the advantages of cable
It is that insulation distance is small between line, space is small, and underground laying is not influenceed without taking up an area face space above by ambient contamination,
Power transmission reliability is high, small to personal safety and surrounding environment interference.But cost is high, construction, maintenance are cumbersome, and manufacture is also more multiple
It is miscellaneous.Therefore, cable is applied to the densely populated and dense area of power network and congested in traffic busy place more；Crossing river, crossing the river, laying down on sea bottom
It can then avoid using large span overhead line.Needing to avoid overhead line to the place of Communication Jamming and needing to consider attractive in appearance or keep away
The occasion for exempting to give away one's position can also use cable.
And due to the architectural characteristic of electric power cable, it is typically all outside parcel insulating barrier and protection using metal as inner core
Layer, some metal quality are softer, and when being connected up, poling difficulty usually occurs, and are easily slid during joint, even
Cable, such as copper core made of the harder metal of some quality, when being attached, when its harder material causes to connect up fixed not
Easily knot, but surface easily slides, and causes not being fixed during wiring so that Joint failure.
Utility model content
Technical problem to be solved in the utility model is that existing cable is not allowed to be fixed easily in joint location, Joint failure,
Its object is to provide a kind of electric power cable poling wiring saver sub, the joint can realize the fixation to cable so that
Cable stable connection, ensure the conveying effect of electric current or communication signal.
The utility model is achieved through the following technical solutions：
Electric power cable poling wiring saver sub, including inner hollow and the connecting tube of both ends open, the connecting tube
Outer wall be cased with mounting seat, mounting seat is protruded to form boss towards the wall of the termination of connecting tube, and two pieces are provided with outside boss
Clamping plate, and boss is arranged between clamping plate, clamping plate is connected with boss, and the middle bent of clamping plate is arc, folder
The passage passed through for cable is formed between tight plate.The position for needing to connect for cable at present is all to use special joint, this
Kind joint design is complicated, and use cost is high, and probability during power equipment maintaining in itself using joint is just very high, and some are tieed up in addition
Environment and region limitation are repaiied, complex joint volume is big, is not easy to convey, especially in some remote mountain areas or maintenance
The small place of quantities, all it is to send an attendant to carry maintained equipment to go over, will if larger or accurate joint
Cause attendant to carry difficult, while oneself can not be repaired and be changed after being damaged before use, cause to waste and bother, this
The joint of conceptual design, its is simple in construction, and easy to use, by the way that the cable connector that two sections need to connect is inserted respectively into
In mounting seat, it is arranged on after joint location is fixed in connecting tube, then be clamped cable by tightening clamping plate so that
Fixation, and connecting tube and can enough plays waterproof action so that joint location service life is longer, while mounting seat and
It can be dismantled between connecting tube, be convenient for assembling, replacing is also very convenient, create a further reduction cost.
When in use in order to prevent the landing of connecting tube and mounting seat, the outer wall of connecting tube is provided with thread segment, installed
The inwall of seat is provided with thread segment, and mutually screws, and using the auto-lock function of screw thread, ensure that service life.
This programme is typically all be used for cable connector position, is all both threads cable so usual, in order to both threads cable all
It is fixed, so the quantitative design of installation is two, and is enclosed on the outer wall of connecting tube, is located remotely from each other in mounting seat
Termination is provided with boss.Sometimes using mounting seat can also, such as only carry out the connection of single cable, the other end
Fix, can be connected by connecting tube with other parts with other parts, every cable will pass through be required for using mounting seat come
It is fixed.
The quantity of boss is two pieces, and along the center line symmetrical setting of mounting seat, wall of the boss towards mounting seat center
The inwall of face and mounting seat is arranged in same curved surface.The diameter of cable is all greater than the thickness of boss, in order that effect must be fixed
Fruit is more preferable, so need to design two boss, and boss is arranged on towards the wall at mounting seat center and the inwall of mounting seat
In same curved surface, prevent from that cable is caused to interfere, while also avoid the unstable stress of boss structure from producing change, cause junction
Fracture.
Connector is provided between clamping plate, and connector is also cross two pieces of clamping plates and corresponding boss.Connector
To be used to control the distance between clamping plate so that cable therebetween through can be fixed for clamping plate, using bolt and
The cooperation of nut, while and can enough prevents from releasing.
The utility model compared with prior art, has the following advantages and advantages：The structure of the joint is simple, peace
It can be dismantled between dress seat and connecting tube, be convenient for assembling, change also very convenient, use cost is low, can realize pair
The fixation of cable so that cable stable connection, ensure the conveying effect of electric current or communication signal.
