Abstract
A fireproof belt converter thermocouple (resistor) is characterized in that a box cover is cylindrical, a wire holder arranged in a wiring box is provided with a metal insert which is provided with two threaded holes, the wire holder is provided with three-core terminals, three grooves are arranged among three-core terminals, which are communicated with each other, and a converter is arranged on the wire holder, the distance of the metal insert can be 36 millimetres and 33 millimetres, the utility model can be respectively installed in domestic and abroad converters simultaneously, the wiring is convenient and simple, and materials can be saved simultaneously.
Description
Technical field: the utility model relates to temperature measuring instrument, belongs to a kind of flame proof thermopair (resistance) of small-sized terminal box specifically, has the thermopair (resistance) of converter simultaneously.
Background technology: the thermopair (resistance) of existing market supply, the profile bulkiness, the operator is made troubles, the explosion-proof level of the product of such generation simultaneously is low, can not assemble converter with three lead-in wire thermal resistances, therefore influence the measuring accuracy of product, usable range is brought limitation, the user feels extremely inconvenient for this reason.
Summary of the invention: the purpose of this utility model provide a kind of small and exquisite, explosive-proof grade is high, simultaneously can assemble three lead-in wires again, and the thermal resistance converter can be installed, and the flame proof belt converter thermopair (resistance) of two kinds of size converters of home and overseas more can be installed.
For finishing the technical scheme that above-mentioned purpose is taked: lid changes into circular-arc in existing thermopair (resistance), junction block in the terminal box is provided with the metal insert of two screws, three core binding posts are set on junction block, three grooves are set between the three core binding posts, article three, groove interconnects, and establishes converter on the junction block.Distance can be 36mm ± 0.1 between two above-mentioned metal inserts, and also the distance that can be provided with is 33mm ± 0.1.Three binding post grooves that are communicated with between the junction block, its wide 3mm, dark 5mm are good, establish thermal resistance service marking A, B, B in that binding post is other simultaneously, but also binding post other establish that thermopair uses+,-polarity mark.Be the cylinder flame proof between above-mentioned junction block and the terminal box, the gap of the faying face of the two is 0.1mm.
The utility model reduce to cover and terminal box between external diameter, easy to use and save material, possess the installation of domestic and international two kinds of size converters simultaneously, and junction block and terminal box are the cylinder explosion suppresion surface, improve explosion-proof precision of the present utility model, and easy-to-connect is simple and reliable.
Description of drawings:
Fig. 1 is this real novel overall structural drawing;
Fig. 2 is the junction block structural drawing.
Embodiment: according to illustrated in figures 1 and 2, wherein lid 1 is a circular arc shaped, be arranged on the metal insert 6 that terminal box 4 interior junction blocks 3 have two screws, three three core binding posts 7 are set on junction block 3, and three grooves 5 are set between three core binding posts, article three, groove 5 is for being interconnected, establish converter 2 on the junction block, distance between 3 two metal inserts 6 in wiring seat can be the converter in 36mm ± 0.1 assembly country, also inserts 6 distances can be arranged to the converter outside 33mm ± 0.1 assembly country, enlarge product function, three three above-mentioned core binding posts are interconnected, and groove 5 is wide to be 3mm, dark in 5mm is good, binding post 7 next doors wherein indicate A, B, the B sign, heat supply resistance uses, simultaneously binding post 7 other be provided with that the heat supply galvanic couple uses+,-polarity mark, between junction block 3 that is provided with in the cavity of the present utility model and the terminal box 4 is the cylinder flame proof, and the gap of the faying face of the two is 0.1mm, can improve explosion-proof level accuracy.
Claims (5)
