A three-phase digital display instrument with quick disconnection of wires

Abstract

The invention discloses a three-phase digital display instrument capable of quickly disassembling and connecting a wire. The three-phase digital display instrument structurally comprises a quick wiring device, connecting blocks, a machine body, a heat dissipation opening and a display screen, wherein the quick wiring device is installed inside the connecting blocks; the back parts of the connecting blocks are fixedly connected with the front side of the bottom end of the machine body; the heat dissipation opening is formed in the left end of the machine body; and the side surface of the display screen is inlaid in the front end of the machine body. According to the device, the wire only needs to be inserted into a back sleeve and a front sleeve and then to be pushed inwards; a lifting rodis clamped inside a fixed outer frame, and the inner core of the wire is in contact with a conductive inner rod, and the wire can be fixed well, so that a screwdriver is not needed for fixing, physical power is saved, quick and convenient disassembling can be realized, and convenience degree in modifying a circuit by a working staff can be improved; the power assisting is very small when the wireenters the front sleeve, and then the resistance is very high when the wire is pushed out, so that the situation that the wire automatically falls off is avoided.

Description

technical field [0001] The invention relates to the technical field of display instrument processing, in particular to a three-phase digital display instrument with quick wire disconnection. Background technique [0002] When the three-phase digital display instrument is used, it needs to be connected to the circuit through wires. The circuit connection needs to be connected manually. Only when the circuit connection is reasonable, can the three-phase digital display instrument display data according to the actual situation. [0003] At present, when the three-phase digital display instrument is connected, it is necessary to turn the nut out with a screwdriver, then insert the wire into the gap between the nut and the fixed port, and then tighten the nut. It is very laborious to tighten and loosen at the same time, but the wiring The workload of the work is generally very large, which will cause sore hands of the staff. Contents of the invention [0004] The main purpose ...
