Abstract
The utility model relates to a heating device for a camera protective hood. The structure is a heat distribution plate made of a rectangular aluminium plate. Heat release glass which is coated with a conductive coating and is provided with two electrode sheets is closely pressed on the heat distribution plate through a press plate and screws. One end of each electrode sheet is connected with an electrode contact arranged on the press plate. The electrode contact is connected with a thermostat connected with a power supply through a guide wire. The utility model has the advantages of small volume, simple structure, easy assembly and maintenance, non-short circuit, and safe use.
Description
The utility model relates to a kind of heater that is used in the camera protective cover.
As everyone knows, because the operating ambient temperature of industrial camera is-10 ℃～+ 40 ℃, and some local nocturnal temperatures of China three northern areas of China can reach-20 ℃～-40 ℃, for guaranteeing the operate as normal of video camera, must give in the protective cover to be heated to more than-10 ℃.In known technology, the heater that is equipped with in the protective cover is to be connected with the temperature controller that is connected to power supply by the lead on the electrode nipple in that the several layers of resistance wire of being separated by with mica in the middle of twining on the support are housed on the heating panel.This heater weak point is that volume is big, the structure more complicated; Particularly short circuit easily causes from the control scaling loss.
The purpose of this utility model is to overcome the deficiency of known technology and heater in a kind of camera protective cover is provided.
The purpose of this utility model realizes by following measure:
The heating panel of rectangular aluminum sheet system, with the ┐ shape pressing plate of heat-resisting, electrically non-conductive material system and screw in compression on it and be coated with heat release glass conducting film and that between two minor faces, be shaped on two silver electrode slices, every strip electrode sheet one termination is connected to electrode nipple, this joint also is contained on the pressing plate, and electrode nipple is connected with the temperature controller that is connected to power supply by lead.
The said conducting film coating material of the utility model is the antimony indium alloy, or tin-indium alloy.Thickness of coating is 0.10～0.05 μ, and its resistance is 6～12 Ω.
The employed power supply of the utility model is 24V, 50HZ.
Advantage of the present utility model is that volume is little, simple in structure; Assembling is easy with maintenance; Can not be short-circuited, safe and reliable.
Description of drawings:
Fig. 1 is an embodiment general assembly schematic diagram provided by the utility model;
Fig. 2 is the A-A cutaway view of Fig. 1.
The embodiment that the utility model is provided is described in further detail in conjunction with the accompanying drawings:
Two long springs of rectangular aluminum sheet system have 90 degree limits and the heating panel 1 of screw hole are arranged thereon, ┐ shape pressing plate 5 and screw 6 with fabroil piece system on it are compressing its thickness 0.10～0.05 μ that is coated with the tin-indium alloy conducting film, resistance is 6～12 Ω's and scribble two heat release glass 2 that the silver electrode slice 3 of spacing is arranged between two minor faces, every strip electrode sheet one termination is connected to electrode nipple 4, this joint also is contained on the pressing plate, and electrode nipple is connected with the temperature controller that is connected to 24V, 50HZ power supply by lead.
