Description
Technical field
The utility model relates to a kind of electronic instrument, and more particularly, it relates to a kind of digital display meter.
Background technology
Digital display meter is a kind of electronic instrument for showing, and all has application at present in all trades and professions, because its display data are accurate and very clear, so instead of pointer instrument in many instances.Extensive utilization is industrial in the display of plc data.Because under the environment of plant of complexity, digital display meter comes luminous by LED, makes people very clear, just can recognize checked data clearly from far place, liking therefore deeply by master workers.
The assembling mode of current digital display meter mostly is and is fixed on housing by screw by circuit board, such assembling mode not only needs the installation portion of the installing hole on circuit board and housing suitable, need higher quality of fit, assemble also cumbersome, need to use the aids such as screwdriver, and also can be less because of space when housing is less, very inconvenient when using the instruments such as screwdriver, cause circuit board to be not easily arranged on housing.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of digital display meter easy to assembly.
For achieving the above object, the utility model provides following technical scheme: a kind of digital display meter, comprise shell and be located at the circuit board in shell, shell includes panel and housing, described circuit board includes first circuit board and second circuit board, described first circuit board and the L-shaped setting of second circuit board, two symmetrical sides in described housing are equipped with the mounting groove for installing first circuit board, described mounting groove is through to housing bottom from the opening part of the relative panel one end of housing, this mounting groove groove width and first circuit board thickness suitable.
Mounting groove both sides in described housing are provided with brace rod, and described brace rod is parallel to mounting groove and arranges.
Described brace rod is provided with limiting section near the one end at shell nozzle place.
Described shell is made up of fire-retardant nylon.
A kind of digital display meter, comprise shell and be located at the circuit board in shell, shell includes panel and housing, described circuit board includes first circuit board and second circuit board, described first circuit board and the L-shaped setting of second circuit board, two symmetrical sides in described housing are equipped with the mounting groove for installing first circuit board, and described mounting groove is through to housing bottom from the opening part of the relative panel one end of housing, this mounting groove groove width and first circuit board thickness suitable.By adopting technique scheme, first circuit board only need slip in housing by mounting groove, just can be arranged in housing by realizing circuit plate without the need to any aid, convenient and swift; And mounting groove is through to housing bottom from shell nozzle, facilitate circuit board to be in place, symmetrically arranged mounting groove is conducive to first circuit board to be fixed on stably in housing, avoids circuit board to produce and rotates.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model digital display meter.
Reference numeral: 1, shell; 2, circuit board; 11, panel; 12, housing; 21, first circuit board; 22, second circuit board; 121, mounting groove; 122, brace rod; 123, limiting section.
Embodiment
With reference to Fig. 1, the utility model digital display meter embodiment is described further.
A kind of digital display meter, the circuit board 2 comprising shell 1 and be located in shell 1, shell 1 includes panel 11 and housing 12, described circuit board 2 includes first circuit board 21 and second circuit board 22, described first circuit board 21 and the L-shaped setting of second circuit board 22, two symmetrical sides in described housing 12 are equipped with the mounting groove 121 for installing first circuit board 21, described mounting groove 121 is through to bottom housing 12 from the opening part of relative panel 11 one end of housing 12, this mounting groove 121 groove width and first circuit board 21 thickness suitable.First circuit board 21 only need slip in housing 12 by mounting groove 121, just can be arranged in housing 12 by realizing circuit plate 2 without the need to any aid, convenient and swift; And mounting groove 121 is through to bottom housing 12 from housing 12 opening part, facilitate circuit board 2 to be in place, symmetrically arranged mounting groove 121 is conducive to first circuit board 21 to be fixed on stably in housing 12, avoids circuit board 2 to produce and rotates; Mounting groove 121 groove width and first circuit board 21 thickness suitable, can prevent circuit board 2 housing 12 produce rock.Mounting groove 121 also can be provided with multiplely installs multiple first circuit board 21 for realizing, and makes neat appearance in housing 12, is convenient to arrange observe; And housing 12 versatility of multiple mounting groove 121 is stronger, can be used for the digital display meter of other functional configuration.
Mounting groove 121 both sides in described housing 12 are provided with brace rod 122, and described brace rod 122 is parallel to mounting groove 121 and arranges.Brace rod 122 adds the contact area of mounting groove 121 and first circuit board 21, is conducive to promoting circuit board 2 and is arranged on stability in housing 12.
Described brace rod 122 is provided with limiting section 123 near one end of housing 12 opening part.The effect of limiting section 123 is positions of spacing second circuit board 22, and what prevent circuit board 2 from installing is too inner, ensures that circuit board 2 is arranged on correct position; Because circuit board 2 is L-shaped, limiting section 123 also can prevent first circuit board 21 from rupturing because overbending produces with the junction of second circuit board 22.
Described shell 1 is made up of fire-retardant nylon.Can prevent shell 1 from causing spontaneous combustion because of intensification, extend the useful life of digital display meter, improve the fire resistance property of digital display meter.
