Circuit board protector

The utility model discloses a circuit board protector which comprises a base and clamping pieces. The base is C-shaped. The upper parts of both ends of the base are respectively provided with a clamping piece. The cross section of the base is L-shaped. The clamping pieces and the lower surface of the base are parallel. By adopting the above technical scheme, the circuit board protector which can solve the problem of insulation of a circuit and makes circuit board mounting fixed is produced. The circuit board protector can well fix a circuit board in a pressure transmitter in the protector, so that the circuit board can be fixed in the casing of the pressure transmitter. The circuit board and the stainless steel casing have great insulation strength. The circuit in the casing of the pressure transmitter has great stability, and does not leave and roll. The pressure transmitter has the advantages of stable performance and strong anti-interference capability. The labor cost is saved.
