Description
Technical Field
The utility model relates to a dual supply change over switch field specifically is a dirt-proof dual supply change over switch.
Background
Double power change over switch extensively applies to the place that can not cut off the power supply such as district, hospital, fire control, chemical industry, metallurgy, it can be with load circuit from main power supply switch to stand-by power supply on, realize switching power supply's function through twist grip or automatic switch-over, current double power change over switch internal element is mostly exposed outside, let the dust attach to its surface very easily, influence its performance greatly, still can lead to the short circuit when serious, influence double power change over switch's life.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a dirt-proof dual power change over switch has solved change over switch and has adhered to the problem of dust easily.
The utility model discloses a realize through following technical scheme:
the utility model provides a dirt-proof dual power change over switch, includes switch main part, control box, power input commonly used, stand-by power supply input and load output, switch main part both sides rigid coupling has the grid piece, switch main part's bottom surface and top surface all are connected with through the trip and inhale grey box, switch main part outside cover has dust proof housing, the control box is leaned on switch main part's one side both sides are equipped with the draw-in groove, dust proof housing be equipped with draw-in groove assorted buckle, dust proof housing opens on the top surface has two recesses.
Preferably, the groove is the same as the length and width of the common power input end and the standby power input end.
Preferably, the dustproof shell is made of heat conducting materials.
Preferably, the grid sheet is insulating rubber.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses a dust keeper with inhale the ash box can prevent effectively that the dust from getting into in the dual supply change over switch or on attaching to binding post, inhale ash box magic and paste fixedly, conveniently change the clearance at any time, keep dual supply change over switch can not be stained with the dust, improve its life.
Drawings
Fig. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention;
fig. 3 is a plan view of the present invention with a dust-proof case installed.
In the drawings: 1. a switch main body; 2. a control box; 3. a common power supply input terminal; 4. an output end of the standby power supply; 5. a load output end; 6. a barrier sheet; 7. an ash absorption box; 8. a dust-proof housing; 9. a card slot; 10. buckling; 11. and (4) a groove.
Detailed Description
Fig. 1 to fig. 3 in the drawings of the specification show a dustproof dual power transfer switch, including switch main body 1, control box 2, common power input end 3, standby power input end 4 and load output end 5, switch main body 1 both sides rigid coupling has barrier piece 6, switch main body 1's bottom surface and top surface all are connected with ash absorption box 7 through the trip, switch main body 1 outside cover has dust proof housing 8, control box 2 is equipped with draw-in groove 9 by switch main body 1's one side both sides, be equipped with on the dust proof housing 8 with draw-in groove 9 assorted buckle 10, dust proof housing 8 top surface is opened has two recesses 11.
In order to facilitate the installation and the disassembly of the dust-proof housing 8 conveniently and quickly, the existence of cables must be considered, and further, the groove 11 is consistent with the length and the width of the common power input end 3 and the standby power input end 4.
In order to achieve better heat dissipation and prevent heat accumulation inside the dual-power transfer switch, further, the dustproof shell 8 is made of a heat conducting material.
In order to prevent arcing, the barrier ribs 6 are isolated from each other, and further, the barrier ribs 6 are made of insulating rubber.
The utility model provides a dustproof dual power change-over switch, common power input end 3, stand-by power input end 4 and load output end 5 put through the cable, according to the user demand, switch between common power and stand-by power, in common use technique, can switch according to automatic switching and also can switch manually, inevitably can adsorb a large amount of dust in dual power change-over switch use, and mainly concentrate on switch main body 1, because switch main body 1 often exposes outside, for more convenient wire disconnection and heat dissipation, dustproof housing 8 in the utility model can block most of dust from entering, select the heat conduction material simultaneously, can not let the inside high temperature, dust absorption box 7 installed on switch main body 1, inside packing silica gel, mica, etc., can adsorb dust and absorb moisture in the air, after a long time, the trip connection also conveniently dismantles the change for dual power transfer switch can not pile up too much because of the dust, leads to the performance to reduce, and life shortens, takes place the condition of short circuit when serious.
In summary, the present invention is only a preferred embodiment, and should not be limited by the present invention, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
