Abstract
The invention provides an aluminium alloy cable branch connecting component for a street lamp. The aluminium alloy cable branch connecting component comprises two main cable cores and a branch wire; the two main cable cores are connected with an aluminium alloy compression joint round pipe, are arranged at the same side, and penetrate through a branch sealing element; the branch sealing element is screwed with a seal protection cap which sleeves the aluminium alloy compression joint round pipe. The mounting method of the component comprises the following steps: a, stripping insulations of ends of the main cable cores and the branch wire according to the length of the aluminium alloy compression joint round pipe in order to expose conductors, and penetrating through the branch sealing element; b, temporarily fixing the conductors by winding tapes and then pre-compressing; c, after pre-compressing, coating conductive paste on the surface and inserting into the aluminium alloy compression joint round pipe, carrying out compression joint by an embracing compression module; d, covering the branch sealing element back to the aluminium alloy compression joint round pipe and screwing with the seal protection cap. By adopting the aluminium alloy cable branch connecting component, a cable is prevented from bending in a narrow street lamp pole, after being subjected to pre-compressing, the wire and the cable and the cable conductors are in compression joint with the aluminium alloy joint pipe and are more compact, so the connection reliability is improved; the wire is in direct contact with the cable conductors, and the electrical performance is improved, so that stable and reliable line operation is achieved.
Description
Technical field
The present invention relates to a kind of street lamp aluminium alloy cable branch's coupling assembling and installation method thereof.
Background technology
Because aluminium alloy cable unit take-back cost is low, make it have natural antitheft characteristic, obtain a large amount of applying in municipal works field in recent years.But because there are special requirement in the joint of aluminium alloy cable and branch, can not link very easily together as copper core cable, special penetrating cable clamp branch must be used, or special tube connector and instrument crimp.
Although aluminium alloy cable allows bending radius less, the space in light pole is very narrow and small, no matter be adopt penetrating cable clamp or tube connector technology, the bending radius of aluminium alloy cable in light pole is all beyond the tolerance band of cable.In fact, because penetrating cable clamp cost is high, it is aluminium connecting tubes compression bonding method that the branch of most street lamp engineering aluminium alloy cable connects what adopt, and cable conductor realizes connection electrically and mechanically by aluminium connecting tubes.Because tube connector is all the through hole that diameter is identical, when introducing branch line, the situation of another lateral deviation pine of branch's side compression can be caused.
The quality of aluminium alloy cable crimp quality directly has influence on the reliability of electrical connection, and bad crimping not only can cause line fault, and also has a great impact the life-span of light fixture.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
For solving the problem, the invention provides method and utensil that a kind of many conductors insert the crimping of aluminium alloy tube connector side by side again after precompressed is circular.Many conductors are arranged side by side, make cable and branch wire be in the same side of aluminium alloy tube connector, cable in lamp stand without the need to bending.Meanwhile, conductor, except with except the electrical contact of tube connector inwall, is also directly closely linked between conductor, is electrically connected more reliable.
The present invention also provides a kind of tube connector directly inserting the elliptical inner of conductor without the need to precompressed.
The technical solution used in the present invention is:
A kind of street lamp aluminium alloy cable branch coupling assembling; comprise and crimp pipe with aluminium alloy and be connected and be positioned at two leader cable cores and the branch wire that aluminium alloy crimps the same side of pipe; described two leader cable cores and branch wire are through branch's seal, and described branch seal is connected with the seal protection cap spiral being placed on aluminium alloy and crimping pipe.
The installation method of a kind of street lamp aluminium alloy cable branch coupling assembling, comprise the following steps: leader cable core and branch wire termination are divested insulation according to the length of aluminium alloy crimping pipe by (1), conductor is exposed, and polishes off the oxide-film on the conductor top layer of leader cable core and branch wire with wire brush;
(2) leader cable core and branch wire are passed branch's seal successively, end conductor aligns, leader cable core and branch wire adhesive tape are wound in insulation go up and close position of exposing conductor of trying one's best is done temporary fixed, in crimping tool, load preloaded module, the conductor insertion die cavity of leader cable core and branch wire is carried out precompressed;
(3) conductive surface after precompressed is smeared a small amount of conductive paste insert aluminium alloy crimping pipe in and rotate a few, in crimping tool, then load confined pressure module crimp;
(4), after having crimped, cleaning conductive paste, adhesive tape, recover aluminium alloy crimping pipe and be connected with the seal protection cap spiral being placed on aluminium alloy and crimping pipe, smearing marine glue at branch's seal and cable core gap by branch's seal.
Beneficial effect of the present invention: the cable or wire in light pole is all positioned at the same side of joint, avoid cable bending in narrow and small light pole, electric wire and cable conductor can put into the less aluminium alloy tube connector of hole size after precompressed, conductor is more closely knit after crimping with aluminium alloy tube connector, improve the reliability of connection, electric wire and cable conductor directly contacts, and compact siro spinning technology together, significantly improve electric property, make circuit stable and reliable operation.
