Abstract
The invention discloses a low-fault cable branch box which comprises a box body 1, wherein an isolating plate 2 is arranged at the middle part of the box body 1; a load switch 3 is arranged at one side of the isolating plate 2; copper bars and cables 4 are arranged at the other side of the isolating plate 2; copper noses are arranged at the end parts of the cables 4; the copper noses are fixed on the copper bars through bolts; a protective cover 5 is arranged at the joint of the copper noses and the copper bars; and the protective cover is fixed on the box body 1 through bolts. The low-fault cable branch box is simple in structure and smart in design, the maintenance security is guaranteed, and wires are prevented from being falsely connected.
Description
Technical field
The present invention relates to the casing field, particularly relate to a kind of low fault electric cable branch box.
Background technology
The existing cable feeder pillar mainly is comprised of casing, cable, busbar, on-load switch, lightning arrester, transducer, cable joint, and wherein cable joint is to be made of an elbow type plug and socket.Patent application document such as Chinese application number 200520111202. X disclosed a kind of low fault electric cable branch box afterwards, it comprises casing, cable, busbar, on-load switch, a lightning-arrest device transducer, cable joint, it is characterized in that cable joint is copper lug, copper lug one end and cable connection, the other end is screwed on the branch end of busbar.Although the cable branch box failure rate is low of this structure is stable, security performance is good.But the copper bar of the cable of this structure and copper lug place be without any safety measure, in the process of maintenance, cause easily the operating personnel to get an electric shock like this.
In sum, for the defective of prior art, need to use especially the low fault electric cable branch box of safety, thereby solve above-mentioned problem.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of low fault electric cable branch box, can solve traditional low failure cable branch easy problem that electric shock occurs in maintenance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of low fault electric cable branch box is provided, comprise casing, the casing middle part is provided with dividing plate, and a side of dividing plate is provided with on-load switch, and the opposite side of dividing plate is provided with copper bar and cable, the end of cable is provided with copper lug, copper lug is bolted on the copper bar, and the junction of described copper lug and copper bar is provided with protective cover, and protective cover is bolted on the casing.
In a preferred embodiment of the present invention, described protective cover is that the transparent plastic material is made.
In a preferred embodiment of the present invention, described protective cover is provided with the phase sequence label.
First cable is received on the copper bar during use, then protective cover is covered the junction of copper lug and copper bar, and be fixed by bolts on the casing, the phase sequence label is being attached on the protective cover, in wiring, be difficult for like this wrong.
The invention has the beneficial effects as follows: the present invention is simple in structure, designs ingeniously, guarantees can also to prevent the wrong line by maintenance safety.
Description of drawings
Fig. 1 is a kind of low fault electric cable branch box of the present invention, schematic diagram.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, a kind of low fault electric cable branch box of the present invention, comprise casing 1, casing 1 middle part is provided with dividing plate 2, and a side of dividing plate 2 is provided with on-load switch 3, and the opposite side of dividing plate 2 is provided with copper bar and cable 4, the end of cable 4 is provided with copper lug, copper lug is bolted on the copper bar, and the junction of described copper lug and copper bar is provided with protective cover 5, and protective cover 5 is bolted on the casing 1.Described protective cover 5 is made for the transparent plastic material.Described protective cover 5 is provided with phase sequence label 6.First cable is received on the copper bar during use, then protective cover is covered the junction of copper lug and copper bar, and be fixed by bolts on the casing, the phase sequence label is being attached on the protective cover, in wiring, be difficult for like this wrong.The present invention is simple in structure, designs ingeniously, guarantees can also to prevent the wrong line by maintenance safety.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
