Description

A kind of power supply instrument

Technical field

The utility model relates to the instrument field, especially a kind of power supply instrument.

Background technology

In the prior art, instrument comprises display window, button and mainboard.Electronic circuit board is moist easily when instrument is used, and rainy weather or contact all and can be corroded in various degree with water makes internal wiring impaired, causes cisco unity malfunction; On the other hand, when catching fire,, can not move, can only leave that it catches fire, can not protect its electronic circuit board because gauge internal has voltage.

The utility model content

The utility model is in order to solve the problem that present instrument mainboard and the easy humidity of circuit are corroded, a kind of power supply instrument to be provided.

In order to achieve the above object, the utility model adopts following technical scheme to realize: a kind of power supply instrument, comprise display window 1, button 2 and mainboard 3, and mainboard 3 is fixed on the shell with display window 1, and shell comprises lid 8 and base 9.

According to the embodiment of the utility model, be embedded with a clear glass 5 on the said lid 8.

According to the embodiment of the utility model, said lid 8 is a rectangular parallelepiped, and is positive recessed, is chamfering all around, and the established angle 6 of upper side and each a pair of convexity of downside, left surface and right flank respectively have one group of limb 7.

According to the embodiment of the utility model, with following one group of mounting hole 10 arranged respectively above the said base, respectively there is a group slot 11 on the left side and the right.

According to the embodiment of the utility model, said base has fixed orifice 12 on four angles.

Owing to adopted this, can prevent effectively that gauge internal mainboard and internal wiring are impaired.
