Degree, extends cool time, strengthens cool time；There is gas leakage pressure release effect in flame proof gap, and in reducing plug casing, explosive is produced
Raw pressure.So, blast produce energy gradually fail, outside of will not igniting because flame proof not by end cap seal every
Quick-fried, even if the most not using end cap, explosion insulation performance is still unaffected.Similar with pin connector, socket connector is also
It is by forming socket insulator flame proof gap and socket contact flame proof gap, making socket inner chamber be isolated from the outside, it is achieved every
Quick-fried effect, also it doesn't matter with end cap for explosion insulation performance, will not lose because of end cap and affect explosion insulation performance.Pin connector and socket are even
Connect device when plugging together, plug together flame proof gap and make pin connector and socket connector mating side form explosion-proof chamber, it is achieved inserting position
Flame proof effect.The contact of pin connector and socket connector is all installed on insulator by matched in clearance, it is possible to use
In pressure line type cable product, and owing to contact can be dismantled, once damage due to contact, contact is dismantled and carries out
Keep in repair or change.When installing casing and being flameproof cabinet, the installation explosion suppresion surface of socket connector makes cabinets cavity with outer
Chamber isolates, it is achieved casing flame proof；When installing casing and being common casing, plug and socket mutually plugs together and can realize inside cable
Flame proof, it is therefore desirable to the socket mounting hole on casing does not has flame proof requirement, it is only necessary to ensure install.
In the present invention is above-mentioned enforcement, Plug contact flame proof gap, plug insulator flame proof gap, socket contact
Flame proof gap, socket insulator flame proof gap and plug together the length dimension in flame proof gap and gap size be all for implementing in
Pin connector or the physical dimension of socket connector set, in other embodiments, those skilled in the art is also
The concrete structure size of flame proof adapter can be combined according to the standard about explosion suppresion surface and different length size and clearance ruler are set
Very little flame proof gap.
