Description
Technical Field
The utility model relates to an online change formula three-colour pilot lamp.
Background
The indicator light is a device for monitoring the operating or position status of the circuit and electrical equipment by means of lights, and the indicator light is generally used to reflect the operating status (power on or off), the operating status (running, shutdown or test) and the position status (closed or open) of the circuit, the electrical equipment, and the like.
The tricolor indicator lamp is one of the indicator lamps, the nuclear power distribution board uses the tricolor indicator lamp (closing, opening, fault or operation, stop, fault) in a large number, the occupancy of the low-voltage panel cabinet in the nuclear power unit is very high, but the current distribution drawer of the type has no product of the indicator lamp which can be replaced on line. And during daily use, the condition that the pilot lamp is dim or damage needs to be changed often appears, and the structure reason of tricolor pilot lamp itself need break off the distribution drawer and just can change when changing, and it is inconvenient to change, also leads to equipment normal use to receive the influence.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the aforesaid not enough, provide one kind and change the convenience, need not to break off the distribution drawer, guarantee the online change formula tristimulus designation lamp of equipment normal use.
The purpose of the utility model is realized like this:
the on-line replaceable three-color indicator lamp comprises a shell, wherein the front end and the rear end of the shell are provided with openings, bayonet grooves are formed in the outer side of the shell along the front-rear direction, an installation buckle is arranged on the outer side of the shell and is clamped behind the bayonet grooves to be connected with the shell, a rear circuit board is arranged inside the shell and close to the rear end, a wiring terminal is arranged on the rear side of the rear circuit board, a terminal plug is arranged on the rear side of the wiring terminal, a panel buckle is arranged on the outer wall of the front end of the shell, a front panel is arranged on the front side of the shell, the circuit board is fixedly arranged on the rear side of the front panel, a plug is arranged on the rear side of the front panel and is matched with the panel buckle, the front panel and the shell can be fixedly arranged in the panel buckle of the plug clamp, a pressing part is further arranged in the middle of the top and the bottom of the front panel, the thickness of the pressing part is smaller than that of the two sides, and the pressing part can be inwards recessed, the front panel can be contracted after the pressing part is pressed by a person, so that the plug is buckled and separated with the panel.
A plurality of heat dissipation holes are formed in the left side and the right side of the shell, and a double-sided convection heat dissipation design is adopted.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses change formula tristimulus designation lamp on line is through making the improvement to the shell structure, through setting up a front panel that can conveniently open and the lock, can just can change the inside LED circuit board of tristimulus designation lamp under the condition of not breaking distribution drawer, need not have a power failure, has guaranteed that equipment normal use is not influenced. Meanwhile, the pressing part is arranged at the top of the front panel, so that the front panel can be pulled out after being pressed more conveniently, and the disassembly and the assembly are labor-saving.
