Problems solved by technology

[0002] Although there are many types of mine flameproof plug connectors used in underground coal mines in my country, there are generally poor contacts of internal conductors, resulting in fuse cores or The terminal post was seriously burned out, which had a great impact on the production of the coal mine. The cost of replacement and maintenance was very hig

Embodiment Construction

[0044] See Figure 1, Figure 2, image 3 and Figure 4 , the shell of plug connector (42) is made up of front cover (30), plug (1), socket (2), socket (3) and rear cover (4).

[0045] As shown in Figure 2, Figure 4 As shown in Figure 9, the front cover (30) is connected with the front cover threaded hole (40) of the plug (1) by three connecting screws (28), and the outer cylindrical flameproof surface of the front cover (30) is inserted into the plug ( 1) In the flameproof surface of the inner cylinder, the two are fitted with clearance to form a flameproof joint surface.

[0046] Referring to Fig. 9 and Fig. 10, the main body of the plug (1) is two concentric hollow rings connected together. In order to save material, the diameter of the upper ring is smaller than the diameter of the lower ring. There are three evenly distributed front cover threaded holes (40) on the end face of the ring, and the front cover (30) is connected to the plug (1) through three M5 connecting scre...

Abstract

A mine-use explosion-proof pin connector relates to a coalmine locomotive power on/off connector. The housing of the pin connector consists of a front cover (30), a plug (1), a socket (2), a socket (3) and a rear cover (4), wherein a wiring terminal (21), flexible connection wiring harness (18), a main spring (19), a moving contact (17), a spring to break (15), a fuse core (14), a wiring column (12), a wiring bolt (25), a wiring stud (26), a wiring terminal insulating sleeve (20), an insulating sheath (16), a fuse core insulating bracket (9), a plug insulating base (13) and an anti-rotation insulating sheath (11) are arranged in the housing; the plug (1) includes a limit stop (22), a convex stage (34) and a stop (10); the socket (2) includes a bearing support (8) and a dustproof cover support (44); a mounting support (45) is arranged on the socket (3); and a pre-tightened main spring cover (41) is arranged between the socket (2) and the socket (3). The pin connector is safe in power utilization.

Description

Technical field: [0001] The invention relates to a flameproof bolt connector for mines, which relates to the field of connecting devices for connecting and disconnecting power on battery locomotives in coal mines. Background technique: [0002] Although there are many types of mine flameproof plug connectors used in coal mines in my country, poor contact with internal conductors is common, which leads to severe burnout of the fuse core or terminal in the connector, which has a great impact on coal mine production. The cost of replacement and maintenance is very high, and it is easy to bring hidden safety hazards in coal mines; in addition, when the old-fashioned plug connectors are plugged in, they are all pushed and inserted by manpower, which is laborious. In order to overcome the above shortcomings and ensure the safe and convenient use of the plug connectors, design A new mine explosion-proof plug connector. Invention content: [0003] The purpose of the present inventi...
