Problems solved by technology

[0002] When designing the function of the instrument, the strong and weak current functions are usually laid out separately. The lower layer is the strong current terminal, and the upper layer is the weak point terminal, which are protected by terminal covers. The new standard is more and more strict on electrical safety. Due to the size requirements, when the terminals are distributed in the upper and lower layers, the space for each layer of terminals is limited, resulting in the upper layer terminals being too close to the edge of the terminal cover, which cannot meet the electrostatic protection requirements, and two-layer terminals and two terminal covers, the two terminals need to be opened separately when wiring cover, and two lead seals are required

Abstract

The invention discloses an instrument with a double-layer linkage flip cover. The instrument comprises an outer flip cover, an inner flip cover, a first shell, a second shell and a circuit board assembly, the circuit board assembly is provided with an upper-layer wiring terminal and a lower-layer wiring terminal, the upper-layer wiring terminal is contained in the first shell, the lower-layer wiring terminal is contained in the second shell, the inner turning cover is rotatably connected in the first shell and used for protecting the upper-layer wiring terminal, the outer turning cover is rotatably connected in the first shell and used for protecting the lower-layer wiring terminal and matching with the inner turning cover to reinforce protection of the upper-layer wiring terminal, the outer turning cover covers the inner turning cover, and the outer turning cover and the inner turning cover are in transmission. The first shell and the second shell are installed in a matched mode to form the whole shell, and when the outer turning cover is turned over, the inner turning cover is driven to turn over in the opposite direction. Due to the fact that the outer turning cover is in linkage with the inner turning cover, wiring can be conducted on the upper layer wiring terminal and the lower layer wiring terminal only by opening the outer turning cover in the wiring process, and wiring steps are simplified.

Description

technical field [0001] The invention relates to an instrument, in particular to an instrument with a double-layer linkage flip cover. Background technique [0002] When designing the function of the instrument, the strong and weak current functions are usually laid out separately. The lower layer is the strong current terminal, and the upper layer is the weak point terminal, which are protected by terminal covers. The new standard is more and more strict on electrical safety. Due to the size requirements, when the terminals are distributed in the upper and lower layers, the space for each layer of terminals is limited, resulting in the upper layer terminals being too close to the edge of the terminal cover, which cannot meet the electrostatic protection requirements, and two-layer terminals and two terminal covers, the two terminals need to be opened separately when wiring cover, and two lead seals are required. Contents of the invention [0003] Aiming at the problems an...
