Abstract
The utility model relates to a high-performance signal amplifier. The main part of a signal amplifier circuit is integrated on a signal amplifier circuit board; the signal amplifier circuit board is arranged in a cylindrical shell; an electric connecting wire of the signal amplifier circuit board passes through preset holes on a front cover plate and a rear cover plate; the front cover plate and the rear cover plate are fixed on front and rear end faces of the cylindrical shell through bolts; and organic silicon pouring sealant is filled in the cylindrical shell. The high-performance signal amplifier can be normally used under a condition of a damp-proof, anti-seismic, corona-resisting and anti-leakage electrode end. The high-performance signal amplifier has the characteristics of excellent cold and hot alternating resistance, anti-ageing property and insulating property.
Description
Technical field:
The utility model relates to the amplifier technical field, and more particularly it has waterproof, antidetonation, cold-resistant, high temperature resistant characteristics by the time, is specially adapted to use under exceedingly odious high temperature or the cold environment.
Background technology:
Existing signal amplifier all is below conventional environment, to use, and its weak point is: when relatively abominable or pair amplifier performance requirement was higher when the residing environment of amplifier, it just can't normally use.For example under protection against the tide, antidetonation, anti-corona and anti-electric leakage extreme environment, use, under the situation that requires equipment cold-and-heat resistent alternation performance, ageing-resistant performance and good insulation preformance, use at needs.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And a kind of high performance signal amplifier is provided; It can normally use under protection against the tide, antidetonation, anti-corona and anti-electric leakage extreme environment, has all good characteristics of cold-and-heat resistent alternation performance, ageing-resistant performance and good insulation preformance simultaneously.
The technological solution of the utility model is following:
A kind of high performance signal amplifier; Comprise cylinder shell, front shroud, back shroud, signal amplifier wiring board and screw; The master unit of signal amplifier circuit is integrated on the signal amplifier wiring board, and the signal amplifier wiring board places cylinder shell, and the electric connection line of signal amplifier wiring board passes the preset hole on front shroud and back shroud; Front shroud and back shroud on the biend of the front and back of cylinder shell, are filled with organic silicon potting adhesive through screw in the cylinder shell.
The indicator light of said signal amplifier circuit stretches out the preset hole on front shroud or back shroud.
The beneficial effect of the utility model is: it can normally use under protection against the tide, antidetonation, anti-corona and anti-electric leakage extreme environment, has all good characteristics of cold-and-heat resistent alternation performance, ageing-resistant performance and good insulation preformance simultaneously.
Description of drawings:
Fig. 1 is the structural representation of the utility model
Among the figure: 1, cylinder shell; 2, front shroud; 3, back shroud; 4, signal amplifier wiring board; 5, screw; 6, electrically connect line; 7, organic silicon potting adhesive; 8, indicator light.
Embodiment:
Embodiment: see shown in Figure 1; A kind of high performance signal amplifier; Comprise cylinder shell 1, front shroud 2, back shroud 3, signal amplifier wiring board 4 and screw 5; The master unit of signal amplifier circuit is integrated on the signal amplifier wiring board 4, and signal amplifier wiring board 4 places cylinder shell 1, and the electric connection line 6 of signal amplifier wiring board 4 passes the preset hole on front shroud 2 and back shroud 3; Front shroud 2 is fixed on the front and back biend of cylinder shell 1 through screw 5 with back shroud 3, is filled with organic silicon potting adhesive 7 in the cylinder shell 1.
The indicator light 8 of said signal amplifier circuit stretches out the preset hole on front shroud 2 or back shroud 3.
Operation principle: be filled with organic silicon potting adhesive 7 in the cylinder shell 1; Compare with general organosilicon; It has item material excellent adhesiveness, yellowing resistance and humidity resistance, is used for coating protection, adhering and sealing and the reinforcing of electronic circuit top electronic component; It is elastomer that organic silicon potting adhesive 7 solidifies the back; Have remarkable cold-and-heat resistent alternation performance, ageing-resistant performance and insulation property glue-line and have good protection against the tide, antidetonation, anti-corona, anti-electric creepage performance, thereby the utility model can normally be used under protection against the tide, antidetonation, anti-corona and anti-electric leakage extreme environment, have all good characteristics of cold-and-heat resistent alternation performance, ageing-resistant performance and good insulation preformance simultaneously.
It uses organic silicon potting adhesive is a kind of flow pattern bicomponent normal temperature cured silicone glue; It is elastomer that material solidifies the back; Have remarkable cold-and-heat resistent alternation performance, ageing-resistant performance and insulation property, glue-line has excellent anti-tide, antidetonation, anti-corona, anti-electric creepage performance.Compare with general organosilicon sealant, have base material excellent adhesiveness, yellowing resistance and humidity resistance.Be used for coating protection, adhering and sealing and the reinforcing of electronic circuit board top electronic component, moisture seal, the waterproof of all kinds of instrument, the embedding of electronic devices and components, module etc.
