Explosion-proof plugs and sockets

Descriptions:

The flexible shutter spring that has a lot of contact surface can guarantee the small contact resistance and low temperature rise meanwhile the force of inserting in and pulling out can be reduced minimally which ensure the normal functions and permanent self-cleaning effect of the plug and socket device is designed at the joint of insert sleeve in the socket of the plug and socket device due to the contact resistance between the plug and socket is changed greatly and the electrical transport properties can be effected directly when the plug and socket device is affected by the surrounding environment (such as temperature , dust, corrosion, etc.)

The interlock switch is equipped with the socket device. The switch is not turned on if it is not rotated and the plug can not be pulled out when the switch is turned on after the plug is inserted into the socket , which the non-live action is realized.

The protective covers are equipped on both plug and socket, which ensure the reliability of the protective degree.

Therefore, the plug and socket device can be used under the extreme conditions.

★ Self-cleaning inserting sleeve, low transmission resistance.

★ Protective covers ensure high degree of protection.

★ Small force of inserting and pulling.

★ IECEx International Approval, ATEX European union certification.
