Instrument housing

Abstract

The invention provides an instrument housing, which comprises a frame (10) and a shell (2), and is characterized in that the shell is rectangular box whose two ends are open, the frame is formed by integrating a middle base plate (4), a front panel (3) and a rear panel (5), the cross section of the frame is H-shaped, the frame can be inserted into the shell from the rear end of the shell, the front end of the shell is fixedly connected with a frame-shaped cover body (1), the lengths of four sides of the inner frame of the cover body are less than the lengths of four sides of the front panel respectively, the left side wall and the right side wall of the rear end of the shell are respectively provided with inverted L-shaped slots (7) in a symmetrical manner, bar-shaped fastening blocks (8) are arranged between the slots, two ends of each fastening block are provided with recessed neck portions (82) respectively, the neck portions can get into the bottom of the corresponding slot from an opening of the slot, the fastening block is provided with a plurality of screw holes (81), and a second screw (9) is screwed in the screw hole and thus abuts against the rear panel. The instrument housing is characterized in that debugging and maintenance of instruments are facilitated, and the housing is easy to assemble.

Description

technical field [0001] The invention relates to an instrument casing. Background technique [0002] The housing of the instrument usually consists of a mid-sole board for installing circuit boards and electronic components, a housing for the mid-sole board, a front panel for installing buttons and displays, and a rear panel for installing input and output terminals; The mid-sole board, front panel, and rear panel are in a separated state, which makes the assembly process of the instrument more complicated; especially when the instrument is debugged as a whole, it is often necessary to turn the mid-sole board to measure the signals of various points on the circuit board or replace electronic components. 1. The front panel and the rear panel are split structures, which are easy to break the connecting wires; in addition, the mid-bottom panel cannot be taken out separately when the instrument is being repaired on site, and the whole machine must be removed from the control cabi...
