Abstract
The utility model relates to a flame-proof wiring terminal which comprises an insulated liner, conducting rods, a wire holder and screw fasteners, wherein a circular groove is formed in the connecting end of the insulated liner; the wire holder is adaptively arranged in the circular groove at the connecting end of the insulated liner; three through holes are correspondingly formed in the insulated liner and the wire holder; the conducting rods are adaptively arranged in the through holes in an injection molding way; thread holes are formed at two end parts of the conducting rods; the screw fasteners are fixedly connected with two ends of the conducting rods; and the insulated liner is connected with the wire holder to form a whole by the screw fastener. According to the flame-proof wiring terminal disclosed by the utility model, due to the adoption of the three-core design, compared with traditional 7-core and 9-core terminals, the flame-proof wiring terminal is smaller in size and lower in cost; and enough space isolation between a material safety circuit and a non-material safety circuit can be ensured; and meanwhile, the volume of a wiring cavity can be effectively reduced.
Description
Technical field
The utility model relates to a kind of binding post, relates in particular to a kind of binding post of flame-proof type.
Background technology
Will there be certain space length in the intrinsic safety loop of mining intrinsic safety type flame-proof switch with non-intrinsic safety loop; The intrinsic safety circuit controls line that general unit uses has only three; And the binding post that is used at present to install intrinsic safety circuit controls line on the market generally all is 7 cores and 9 cores; The profile of product is big, cost is high, and the spatial separation in intrinsic safety loop and non-intrinsic safety loop is big inadequately.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, provides a kind of and can effectively reduce manufacturing cost, simple and reasonable, the flame-proof type binding post that can reduce the wire connection cavity volume.
For realizing above-mentioned purpose, the utility model adopts a kind of flame-proof type binding post, comprises insulating cell, conducting rod, junction block and screw fastener; The link of insulating cell is provided with a circular groove; Junction block is adaptive to be arranged in the link circular groove of insulating cell, and correspondence is provided with a plurality of through holes on insulating cell and the junction block, and conducting rod is through pressing adaptive being arranged in this through hole of mode of annotating; The both ends of conducting rod are provided with screwed hole; Screw fastener is fixedly connected setting with the two ends of conducting rod, and insulating cell is connected in aggregates with junction block through screw fastener, and the corresponding annular with junction block of insulating cell is provided with three through holes; Three adaptive being arranged in three through holes of conducting rod, six groups of screw fasteners are fixedly connected with the two ends of three conducting rods respectively.
The utility model further is provided with again, between three through holes on the end face of the outer end of insulating cell and junction block, is provided with dividing plate.
The utility model further is provided with again, and screw fastener comprises plain cushion, bullet pad and screw.
In sum; The beneficial effect of the utility model is: what the utility model adopted is the binding post of 3 cores, for connecting the intrinsic safety loop, enough uses, than 7 traditional cores and 9 core binding posts; The profile of product is littler; Cost is lower, and has guaranteed between intrinsic safety loop and the non-intrinsic safety loop enough spatial separation to be arranged, and can effectively reduce the wire connection cavity volume simultaneously.
