Embodiment Construction

[0056] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0057] like Figures 1 to 3 As shown, the explosion-proof lead wire connector is used to electrically connect the inner lead wire 5 of the explosion-proof chamber and the outer lead wire 6 of the explosion-proof chamber, so as to ensure that the sparks generated by the lead wires in the explosion-proof chamber 8 of the explosion-proof lamp will not escape the explosion-proof chamber, preventing The explosive gas outside the explosion-proof chamber 8 is ignited.

[0058]In a preferred embodiment of the present invention, the flameproof lead wire connector includes a sealing sleeve 11 and a...

Abstract

The invention relates to an explosion protection lead wire connector and an explosion protection lamp. The explosion protection lead wire connector is used to electrically connect an explosion protection indoor lead wire (5) and an explosion protection outdoor lead wire (6), and the explosion protection lead wire connector comprises an electric conduction column (12) and a sealing sleeve (11), two ends of the electric conduction column (12) are provided with a leading-in end (121) and a leading-out end (122) which are electrically connected with the explosion protection indoor lead wire (5) and the explosion protection outdoor lead wire (6) respectively; the sealing sleeve (11) is connected with an explosion protection chamber (8) in a dismounting and sealing way, the electric conduction column (12) penetrates out of the sealing sleeve (11) from the inner part of the explosion protection chamber (8), and an insulating layer (13) is arranged between the electric conduction column (12) and the sealing sleeve (11). The connection reliability and the mechanical strength of the explosion protection lead wire connector can be ensured by the explosion protection lead wire connector, thereby ensuring the reliable explosion protection performance. Moreover, the explosion protection lead wire connector and the explosion protection chamber are connected in the dismounting and sealing way, therefore, the explosion protection lead wire connector is easy to replace and the universality is great.

Description

technical field [0001] The invention belongs to the field of lighting. Specifically, the invention relates to a flameproof lead wire connector and a flameproof lamp with the flameproof lead wire connector. Background technique [0002] With the rapid development of industries such as petroleum and chemical industry, lighting fixtures are used more and more widely in production, storage and rescue, with more and more varieties. How to prevent the accidental explosion of lighting fixtures in explosive gas hazardous places has become a very important issue. Since lighting fixtures inevitably generate electric sparks or form hot surfaces during work, once they meet the explosive gas mixture at the production or rescue site, it will cause an explosion accident, directly endangering national property and the lives of citizens. Therefore, as the most widely used lighting fixture, its explosion-proof technology has already attracted widespread attention and great attention. [00...
