Abstract
A distributing box for mine intrinsically safe circuit comprises an upper case and a lower case, wherein a plurality of wire through holes are respectively arranged on the wall of the lower case, a circuit board on which a plurality of terminal seats are arranged is fixed in the lower case, each terminal seat is provided with a plurality of terminals which are connected with each other through a copper foil. The utility model provides a distributing box for mine intrinsically safe circuit which is capable of connecting a plurality of branches and convenient for use and maintenance.
Description
Technical field
The utility model relates to a kind of junction box, particularly a kind ofly is applicable to being connected or the junction box of separated time of transducer and substation and other intrinsic safety type equipment.
Background technology
Present known circuit junction box all is the wiring pillar, and the line pressure that will connect is received on the binding post together then exactly, and its weak point is that when too much as if separated time, wiring is very inconvenient, and the back that carefully connects the wire is safeguarded inconvenient.
The utility model content
At the defective of above-mentioned prior art, the purpose of this utility model provides and a kind of can connect separated time more, and operation and maintenance is mine intrinsic safety circuit junction box easily.
For achieving the above object, the utility model adopts following technical scheme:
A kind of mine intrinsic safety circuit junction box, comprise upper case and lower case, several threading holes are set respectively on the wall of described lower case, circuit board is fixed on the inside of described lower case, several wiring column bases are set on the described circuit board, on each described wiring column base several binding posts are set, each described binding post links to each other by Copper Foil respectively.
Mine intrinsic safety circuit junction box of the present utility model, wherein said circuit board is fixed on the inside of described lower case by set bolt.
Mine intrinsic safety circuit junction box of the present utility model, wherein said upper case and described lower case pass through bolt.
Mine intrinsic safety circuit junction box of the present utility model, wherein said wiring column base is four, on each described wiring column base six binding posts is set.
Mine intrinsic safety circuit junction box of the present utility model, wherein said threading hole is four.
Mine intrinsic safety circuit junction box of the present utility model, wherein said upper case and described lower case are shaped as cuboid, square, cylinder, triangle, polygon.
Because each binding post links to each other by Copper Foil, so just do not need the line pressure that will connect together, as long as be connected on the binding post of correspondence just passable, easy to use, easy to maintenance.
Description of drawings
Fig. 1 is the front view of the utility model mine intrinsic safety circuit with junction box;
Fig. 2 is the circuit board schematic diagram of the utility model mine intrinsic safety circuit with junction box.
Embodiment
Below in conjunction with accompanying drawing the execution mode of the utility model mine intrinsic safety circuit with junction box is elaborated.
Referring to Fig. 1 and Fig. 2, the utility model mine intrinsic safety circuit junction box, comprise upper case 1 and lower case 2, upper case 1 is fixing by bolt 3 with lower case 2, threading hole 4 is set respectively on the wall of lower case 2, and circuit board 5 is provided with four wiring column bases 6 by the inside that set bolt 3a is fixed on lower case 2 on the circuit board 5,6 binding posts 7 are set on each wiring column base 6, and each binding post 7 links to each other by the Copper Foil 8 of circuit board 5 respectively.
During use, open upper case 1, each line that will connect is passed the threading hole 4 nearest with the binding post that will connect 7, and each binding post 7 fixing getting final product that are provided with on line that will connect and the circuit board 5, because each binding post 7 links to each other by Copper Foil 8, so just do not need the line pressure that will connect together, as long as be connected on the binding post 7 of correspondence just passable, easy to use, easy to maintenance.
Circuit board of the present utility model can be provided with any a plurality of wiring column base 6 as required, on each wiring column base 6 any a plurality of binding post can be set, and threading hole 4 also can be provided with individual arbitrarily as required.The shape of junction box can also be square, cylinder, triangle, polygon etc. except cuboid.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection range of claims of the present utility model.
