Abstract
The utility model provides a low fault cable branch box, which is characterized in that a cable is a copper nose; the connection is firm, and the contact is tight. The appearance of the situation of accidents frequently happening caused by the poor contact of the existing cable joints can be avoided. In addition, the utility model has the advantages of simple structure, convenient installation and low cost.
Description
Technical field the utility model relates to a kind of circuit branch equipment, particularly a kind of low failure cable feeder pillar.
Background technology existing cable feeder pillar mainly is made up of casing, cable, busbar, on-load switch, lightning arrester, transducer, cable joint, wherein cable joint is to be made of an elbow type plug and socket, elbow type plug is made of by the spiral connection two orthogonal conduits, its end and cable connection, the other end is inserted in the socket that is fixed on the busbar.The cable joint that this kind elbow type plug constitutes in use has the deficiency of the following aspects: 1, poor safety performance, the failure rate height, its reason mainly is loose contact, first elbow type plug is to be connected through spiral by two conduits to constitute, in practical operation, two conduits often are difficult to twist tightly, and this place easily causes the situation of loose contact; It two is, elbow type plug is to connect by socket with busbar, and the connecting mode of this kind insertion also easily causes loose contact.2, structure is complicated, installation is inconvenient, one, and elbow type plug need be equipped with socket; Its two, plug is to be connected through spiral by two conduits to constitute, it is complicated that these two aspects form its structure, this structure is brought inconvenience to installation, especially elbow type plug comes rotary guide pipe to carry out the spiral connection by a stubborn silk, the difficult application of force, and this also is the reason that causes two conduit loose contacts.3, cost is higher, and the one, the cost of parts, the 2nd, installation cost.
The summary of the invention the purpose of this utility model is often to break down owing to loose contact at the cable joint place at the existing cable feeder pillar, the deficiency of its poor safety performance, and it is low to propose a kind of failure rate, the cable branch box that security performance is good.
Can realize the purpose of this utility model by following technical proposals, a kind of low failure cable feeder pillar.It comprises casing, cable, busbar, on-load switch, lightning arrester, transducer, cable joint, it is characterized in that cable joint is a copper lug, copper lug one end and cable connection, and the other end is fixed on the branch end of busbar by screw.
Be covered with an insulating lid for improving fail safe, copper lug and busbar branch end exposed section.
Effect of the present utility model is: 1, failure rate is low, and is stable, and security performance is good, and this is that mainly copper lug and busbar are fixedly connected by screw, and the connection form is fastening, difficult loosening, the situation of loose contact can not occur; 2, simple in structure, easy for installation; 3, cost reduces, first copper lug and elbow type plug and socket mutually when cost greatly reduce, it two is to install simply, makes the installation cost reduction.
Below in conjunction with accompanying drawing the utility model is further set forth
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model
Accompanying drawing 2 is the enlarged diagram at A place in the accompanying drawing 1
Embodiment is provided with on-load switch 2 referring to accompanying drawing 1,2 in the left side of casing 1, and its end connects with an end of busbar 3, and the other end connects with transducer 4, for avoiding thunderbolt, also is provided with lightning arrester 5 in the left side of casing 1.Busbar 3 is three branches (quantity of branch is fixed by designing requirement) at the right half part of casing 1, the branch end of busbar 3 is closely fixing by screw and copper lug 6, the other end of copper lug 6 is inserted in the termination of cable 7, and by the fastening connection, copper lug 6 is covered with insulating lid 8 with the exposed section of busbar 3 branch end.Be to improve fail safe, but in casing 1 the mounting strap electrical indicator, the alert circuit is charged.For ease of searching cable fault rapidly, in casing 1, also can connect the short trouble indicating device.
Claims (2)
1, a kind of low failure cable feeder pillar, it comprises casing, cable, busbar, on-load switch, lightning arrester, transducer, cable joint, it is characterized in that cable joint is a copper lug, copper lug one end and cable connection, the other end is fixed on the branch end of busbar by screw.
2, low failure cable feeder pillar according to claim 1 is characterized in that copper lug and busbar branch end exposed section are covered with an insulating lid.
