Abstract
The utility model discloses a plug of an explosion-proof connector. The plug comprises a plug body (1), a head housing body (2) and a head outer housing (3). The head outer housing (3) is sleeved on the head housing body (2). A head of the head outer housing (3) is provided with an explosion-proof sealing ring (4). The head of the head outer housing (3) and the explosion-proof sealing ring (4) are arranged in an explosion-proof wire protection sleeve (5). A back part of the head outer housing (3) is sleeved with a dustproof cover (6). The plug body (1) is located in the head housing body (2). A bottom of a thread groove of the head outer housing (3) is provided with a clamping slot. The head housing body (2) is inserted with a bayonet pin (7). A body of the bayonet pin (7) is located in the head housing body (2). An upper end of the bayonet pin (7) is located in the clamping slot. The bayonet pin (7) and the clamping slot are in rotation connection. The head housing body (2) is rotated around the bayonet pin. According to the plug of the explosion-proof connector, the positioning of the head housing body of an explosion-proof plug in the head outer housing is effectively facilitated, the insertion of the explosion-proof plug into a socket is facilitated, and the falling of a conducting wire from a solder cup mouth caused by the rotation of the head housing body is prevented.
Description
Technical field
The utility model relates to a kind of plug of explosion-proof connector.
Background technology
Widely used explosion-proof connector plug just uses explosion-proof and cap and tight between explosion-proof shell and explosion-proof casing in petroleum works at present, guaranteed that explosion-proof casing can't carry out axial endplay in explosion-proof shell, but do not have effective measures to prevent explosion-proof casing around the rotation of its axis, the wire that welds on the jack that causes easily is from quality problems such as the weldering rim of a cup come off.
Summary of the invention
The utility model provides a kind of plug of explosion-proof connector, and it not only makes explosion-proof plug casing position problem effectively in a shell, is conducive to plugging together of explosion-proof plug and socket, and prevents that the casing rotation from causing that wire comes off from the weldering rim of a cup.
The utility model has adopted following technical scheme: a kind of plug of explosion-proof connector, it comprises plug body, between casing and a shell, casing is on casing, head at a shell is provided with explosion-proof sealing ring, head and the explosion-proof sealing ring of shell are arranged in the explosion-proof wire bushing, in a shell rear sleeve dust cap is arranged, plug body is positioned at casing, bottom at the thread groove of a shell is provided with draw-in groove, be inserted with bayonet lock in casing, the main body of bayonet lock is positioned at casing, and the upper end of bayonet lock is positioned at draw-in groove, bayonet lock and draw-in groove are for being rotationally connected, and casing rotates around bayonet lock.
Described draw-in groove is the R3 groove, and the length of draw-in groove is 22 ~ 25mm.Described dust cap is provided with brace, and brace is connected with chain by rivet.
The utlity model has following beneficial effect:: the utility model is to have added bayonet lock between explosion-proof plug casing and a shell, solved like this orientation problem of explosion-proof plug casing in a shell, be conducive to plugging together of explosion-proof plug and socket, and solved casing and rotate the wire that causes from quality problems such as the weldering rim of a cup come off, be applicable to the explosion-proof connector of all models.
