Abstract
An anti-explosion multi-wire-outlet terminal comprises an anti-explosion threaded sleeve. A fixing plate is disposed at the bottom of the threaded sleeve and used for fixing a plurality of Teflon cables. Epoxy pouring resin is disposed between the interior of a threaded sleeve shell and the gaps of the cables and used for filling the gaps between the interior of the threaded sleeve shell and a plurality of bare copper wires so as to achieve physical and electric isolation. A locking nut is disposed outside the threaded sleeve shell and used for locking and fixing. A plurality of wire outlet terminals are disposed on one anti-explosion terminal sleeve and used for transition wire outlet between the main cavity and the auxiliary cavity of an anti-explosion electric product, wire outlet processes are simplified greatly, use amount of the anti-explosion terminal sleeve is reduced, electric insulation problems among wires are solved, electric component product integration is achieved, and the outer threaded part is an anti-explosion thread which satisfies an anti-explosion requirement and has a locking function; outlet box space and various possible causes of electric insulation are comprehensively considered in terms of mechanical structures, brand new design from multiple aspects and angles is performed, overall machine size is lowered, and product cost is lowered greatly.
Description
Technical field
This technology belongs to explosion-proof special purpose parts, crosses line for ex electrical product is special.
Background technology
Along with the continuous progress that the modernization of industry is produced, especially constantly require to compress profile to flame proof production, this just makes an electric components product will make integrated, under the prerequisite meeting various performance, require that electric product accomplishes volume minimization, the space of such wire connection cavity will reduce a lot, and namely the volume of flameproof enclosure reduces.
Summary of the invention
The object of the invention is the problem that can only realize single conductor outlet in order to solve existing ex electrical product, and propose a kind of explosion-proof special outgoing lines terminal, it can realize the outlet of many wires, and can meet the requirement of explosion insulation performance and the requirement of electric property.So explosion-proof terminal sleeve is provided with many outlets, Wiring technology is enormously simplify out to there being the electrical apparatus for explosive atmospheres of multiple tap outlet, effectively reduce the usage quantity of explosion-proof terminal sleeve, and the Insulation Problems solved between wire, simultaneously, make outlet attractive in appearance and greatly reduce costs, realizing electric components Products integration, flameproof enclosure volume reduces.
For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of explosion-proof special multiple wire outgoing terminals attached bag draws together thread bush, thread bush outside is furnished with nut, thread bush inside is provided with fixed head, many aviation polytetrafluoroethylcable cable lines by fixed head uniformly across thread bush inside.Described explosion-proof special outgoing lines terminal inner is provided with many outlets, evenly separates between each outlet; Flame proof thread is established in outside, realizes flame proof, and is furnished with locking nut.
Described thread bush inside is zigzag structure.
The part of described many aviation polytetrafluoroethylcable cables in the middle of thread bush will remove the long insulated hull of 8-10mm, exposes bare copper wire.Frock is used in manufacture craft, multi-cable is made to specify that the distance of requirement is separated equably by normal voltage, reach the instructions for use of electric property, between enclosure interior and cable gap with epoxy resin E44 add curing agent 650 by 1: 1 formula water, after epoxy resin solidifies, do turn-to-turn and withstand voltage test by the rated voltage of design.
Described explosion-proof special outgoing lines terminal has heat-resisting cold resistant property.
The explosion-proof terminal of described outgoing lines is used for the transition outlet between fire-proof motor major-minor chamber.
The present invention is reasonable in design, an explosion-proof terminal sleeve is provided with multiple outlet terminal, Wiring technology is enormously simplify out to there being the electrical apparatus for explosive atmospheres of multiple tap outlet, effectively reduce the usage quantity of explosion-proof terminal sleeve, and meet explosion insulation performance requirement and electrical performance demands, meanwhile, make outlet attractive in appearance and greatly reduce costs, realize electric components Products integration, effectively reduce flameproof enclosure volume.
Accompanying drawing explanation
Fig. 1 is cutaway view of the present invention;
1, aviation polytetrafluoroethylcable cable, 2, thread bush, 3, epoxy sealing resin, 4, nut, 5, fixed head.
Embodiment
Below in conjunction with drawings and embodiments, the present invention will be further described in detail.
See Fig. 1, explosion-proof special multiple wire outgoing terminals attached bag of the present invention draws together thread bush 2, and thread bush external screw thread is flame proof thread, and the flame proof screw-internal thread fit on rebound between electrical apparatus for explosive atmospheres major-minor chamber forms threaded flame-proof type face, can meet explosion insulation performance requirement; Thread bush outside is furnished with nut 4, after thread bush installation is fixing, is locked, prevents from coming off with nut, form dual fail-safe.
Thread bush 2 inside is zigzag structure, and increase the contact area of epoxy sealing resin 3 and thread bush 2, increasing friction force, makes epoxy sealing resin 2 and aviation polytetrafluoroethylcable cable 1 can not be ejected when blasting, and increases mechanical strength.
Thread bush 2 inside is provided with fixed head 5, frock is used according to technological requirement when making, the distance of requirement distance equably separately between every root cable that many aviation polytetrafluoroethylcable cables 1 are specified by normal voltage, in case interconnect between cable, reaches the instructions for use of electric property.The part of described many aviation polytetrafluoroethylcable cables in the middle of thread bush will remove the long insulated hull of 8-10mm, exposes bare copper wire, there is gap when preventing copper cash tape insulation skin from pouring into a mould, and forms propagation of explosion.Water with epoxy sealing resin 3 (epoxy resin E44 adds curing agent 650 and fills a prescription by 1: 1) between thread bush 2 enclosure interior and aviation polytetrafluoroethylcable cable 4 gap, after epoxy sealing resin solidifies, do turn-to-turn and withstand voltage test by the rated voltage of design.According to the condition used, can make 3-21 core flexible cable (multicore), the square number of cable is generally between 0.75-1 square millimeter, and the rated voltage of cable is 690V.
Explosion-proof special outgoing lines terminal of the present invention has heat-resisting cold resistant property, meets the requirement of in GB/T3836.1-2010 the 26.8th and 26.9.
The explosion-proof terminal of outgoing lines of the present invention is used for the transition outlet between fire-proof motor major-minor chamber, be mainly used in the outlets such as electric temperature element, heating tape, effectively reduce the usage quantity of explosion-proof terminal sleeve, consider space and the various possible cause of electric insulation of outlet box mechanical structure comprehensively, many-side has carried out brand-new design with multi-angle, reduce machine volume, significantly reduce product cost.
