Problems solved by technology

[0002] The current instrument casing mainly includes the front cover, the housing, and the front cover is made of the same material as the body and the base. Usually, the rear side of the housing is provided with wiring terminals, and the connecting and disconnecting terminals are exposed to the air, which may cause corrosion of the connecting and disconnecting terminals. Most of the wiring diagrams of the instrument are printed on self-adhesive paper and pasted on one side of the body. It is extremely inconvenient for the wiring personnel to use. They need to face the wiring terminals and the wiring diagram on the side, and the operation time is long.
Secondly, in industrial occasions, especially in hazardous areas, there is still a certain requirement for the protection level of the front cover of the instrument. The front cover of the ordinary instrument case is not pressure-resistant and fragile, and is often not suitable for applications in hazardous occasions for this reason.

Abstract

The invention discloses an instrument shell, comprising a shell and a front cover and further comprising a rear cover; the shell consists of a rear plate and four side plates fixedly connected on the rear plate and is provided with an opening end; the front cover is used for sealing the opening end of the shell; one side of the rear plate opposite to the opening end is arranged as the external side of the rear plate; grid wiring terminals are distributed on the external side of the rear plate; the rear cover is connected with the rear plate by a rotating shaft; the rotating shaft is arranged on the rear plate and the rear cover rotates with the rotating shaft as the axle centre; the rear plate is further provided with a locating device; the rear cover and the rear plate at the coincide position are fixed through the locating device. The purpose of the invention is to provide an instrument shell which not only can be used for preventing the wiring terminals, but also is convenient for wiring staff to observe; and the instrument shell has the advantages of compact structure, convenience in mounting / dismounting and practicability and simpleness.

Description

technical field [0001] The invention relates to an industrial automation instrument casing, in particular to an instrument casing with a rotatable back cover. Background technique [0002] The current instrument casing mainly includes a front cover, a housing, and the front cover is made of the same material as the body and the base. Usually, there are wiring terminals on the rear side of the housing, and the connecting and disconnecting terminals are exposed to the air, which may cause corrosion of the connecting and disconnecting terminals. Most of the wiring diagrams of the instrument are printed on self-adhesive paper and pasted on one side of the main body. It is extremely inconvenient for the wiring personnel to use. They need to face the wiring terminals and the wiring diagram on the side, and the operation time is long. Secondly, in industrial occasions, especially in hazardous areas, there is still a certain requirement for the protection level of the front cover of...
