Abstract
Provided is a double groove type four-way explosion-proof junction box. The junction box comprises a housing composed of an upper housing and a lower housing, wherein the upper housing is movably connected with the lower housing, and the housing is of a four-way type structure. A wiring board is arranged in an inner cavity formed by the upper housing and the lower housing, a groove I is arranged in a combined position of end portions of the upper and lower housings, and a groove II is arranged in another combined position of end portions of the upper and lower housings, wherein the groove I is used for sealing the inner cavity formed by the upper and lower housings, the groove II is used for alleviating the line tension, and the groove II is arranged outside the groove I. According to the utility model, the structure is simple and compact, sealing of a line outlet is simple, and groove structures are arranged to effectively alleviate the line tension.
Description
Technical field
The utility model relates to a kind of two groove type four-way explosion-proof terminal boxes.
