Abstract
Provided is an enclosing housing for an electric power instrument, comprising a terminal in-and-out end, an enclosed metal casing, a control panel, and plate troughs, where the control panel and the binding post in-and-out hole are respectively installed at two opposite sides of the metal casing; the plate troughs are paired to be fixed inside the metal casing; and the positions of the paired plate troughs are respectively at two sides of the position where the control panel and the binding post are located. The enclosing housing of the utility model replaces the conventional plastic housing into metal casing, with four sides of the metal casing being sealed. If arranged in such an enclosing housing, the electronic instrument can meet the waterproof and dustproof requirement and prevent EMC rate-4 static. Moreover, the metal casing facilitates heat radiation, thereby effectively solving the plate heat radiation of an electronic instrument, satisfying the requirement for security on some special occasions, enhancing the safety and reliability of an electronic instrument, and improving the applicability.
Description
Technical field
The utility model relates to the power distribution automation field, specifically relates to a kind of closure casing of electric instrument, makes electric instrument satisfy the requirement of the authentication of EMC4 level, dustproof, anti-water smoke.
Background technology
At present, power distribution automation development rapidly, electric instrument is essential in social development, can accurately measure the various electrical quantitys such as voltage, electric current, frequency, power, consumed power of electric system.Yet the occasion that some is special needs electric instrument on based measurement, to possess dustproof, waterproof, antifog function, and can satisfy the high-grade static requirement of prevention.Therefore, a kind ofly can prevent dust, the closure casing of the electric instrument of waterproof, antifog, anti-high-grade static seems very necessary.More common electric instrument mostly is a plastic casing on the current market; The porous of housing own or its button separate with display panel; Do not reach the requirement of dustproof, waterproof, antifog and plate heat radiation; And can not pass through EMC4 level electrostatic experiment, such instrument just is difficult to satisfy the electric parameter measurement of special occasions.
Summary of the invention
The problem that the utility model will solve is: the use of electric instrument need be satisfied the requirement of dustproof, waterproof, antifog, anti-high-grade static.
The technical scheme of the utility model is: a kind of closure casing of electric instrument; Comprise terminal in-out end, enclosed metal shell, control panel and plate draw-in groove; Control panel and connection terminal manhole appendix are installed in the relative both sides of metal shell respectively, and the plate draw-in groove is fixed on metal shell inside in pairs.
Described wiring in-out end is provided with at least two rows.
Control panel covers the layer of transparent plastic foil outward.
The material of metal shell is the al-mg-si alloy of 6 series.
The beneficial effect of the utility model is: the closure casing of the electric instrument of the utility model changes plastic casing of the prior art into metal shell; Metal shell seals on four sides; There is the terminal manhole appendix at the back side; There is control panel in the front, and the plastic foil of control panel outside is waterproof and dustproof, electrostatic prevention effectively.Metal shell inside has the plate draw-in groove to be used for fixing plate, and the metal shell that assembles belongs to closure casing, has reached waterproof and dustproof, has prevented the specific (special) requirements of EMC4 level static, and effectively solved the plate heat dissipation problem of electric instrument.Satisfied the safe handling of electric instrument under the special occasions.Thereby electric instrument is more safe and reliable, and applicability is stronger.

Fig. 3 is the structural representation of the utility model plate draw-in groove part.
Embodiment
Provide specific embodiment below in conjunction with accompanying drawing, further the utility model is elaborated.
As shown in Figure 1; The utility model comprises terminal in-out end 1, enclosed metal shell 2, control panel 3 and plate draw-in groove 4; Control panel 3 and connection terminal manhole appendix 1 are installed in the relative both sides of metal shell 1 respectively, and in practical implementation, control panel 3 is embedded in the front of metal shell 2 here; Wiring in-out end 1 is at metal shell 2 back sides, and the quantity of Wiring port can be made as two rows according to the number of terminals of electronic instrument perhaps more than two rows; Plate draw-in groove 4 is fixed on metal shell 2 inside in pairs, is used for fixing the pcb board spare of electric instrument.
Further, one deck plastic foil is arranged, be used for better plaing a part waterproof and dustproof, electrostatic prevention in the outside of control panel 3.
The undeclared part that relates in the utility model is identical with prior art or adopt prior art to realize.
