Abstract
The utility model discloses a fastener for outer heater windings in a high-pressure oil box of a high frequency medical diagnostic X-ray machine. The fastener comprises a cover plate and a winding framework with a slot, and is characterized in that the outer heater windings sleeved with a silicone rubber protective sleeve are placed in the slot, and a silicone rubber plate is filled on the outer sides of the outer heater windings; the rest gaps among outer heater windings, the silicone rubber plate and the slot are filled with the silicone rubber 704; and the cover plate covers the outer side surface of the winding framework. The fastener has high insulating strength and relatively simple fabrication technology, and can effectively solve the problems that the windings can not bear high voltage of 90 kV to the ground for three minutes and the packaging technology is troublesome.
Description
Technical field
This utility model relates to a kind of medical diagnosis high frequency X-ray production apparatus spare and accessory parts, is specifically related to a kind of medical diagnosis high frequency X-ray production apparatus pressure-oil tank filament exterior loop component.
Background technology
The diagnosis principle of medical diagnosis high frequency X-ray production apparatus mainly is through the back of filament heating in advance electrons emitted; Electronics quickens to beat on black target surface to produce X ray through the high pressure that is added on the filament again, when X ray passes human body, after the absorption of human body different tissues; The strong and weak difference of remaining X ray; Make the sensitization degree of film just different like this, just on film, formed a sub-picture, the doctor diagnoses patient's the state of an illness according to this width of cloth image.
This structure filament exterior loop component is that the X-ray tube filament of X-ray production apparatus provides filament voltage, in the national standard X-ray production apparatus is exported the High-frequency machine that reaches 150KV, and heater winding must satisfy the voltage-to-ground of 3 minutes 90kV; This proposes very high requirement just for coil insulation over the ground; At present epoxy encapsulation is adopted in the insulation of coil,, solidify not exclusively because the allotment ratio of epoxy resin is improper; To shrink behind the epoxy resin cure; And trickle slit is arranged between the coil rack, this trickle slit with solidify the voltage-to-ground not exclusively cause coil to be difficult to bear 3 minutes 90kV, perhaps can not enter the voltage-to-ground of 90kV at all; Also have this packaging technology cumbersome, be difficult to grasp the allotment ratio of epoxy resin, because these fatal shortcomings do not reach specification requirement, so just be designed to top new construction again.
The utility model content
In view of above-mentioned weak point, the purpose of this utility model is how to provide a kind of structural manufacturing process simple and can solve the medical diagnosis high frequency X-ray production apparatus pressure-oil tank filament exterior loop component that coil can bear the high voltage problem of 3 minutes 90kV over the ground.
This utility model has adopted following technical scheme in order to achieve the above object: a kind of medical diagnosis high frequency X-ray production apparatus pressure-oil tank filament exterior loop component; This filament exterior loop component is that the filament exterior loop that coiling is good puts the silicone rubber protective sleeve; Pack in the wire casing of coil rack; Insert the outside of filament exterior loop with silicane rubber plate, the lead-out wire with the filament exterior loop puts with silicone rubber tube then, utilizes 704 silicon rubber sealants to fill remaining space again; At last lateral cover plate is covered, the filament exterior loop just is closed in the wire casing of coil rack fully like this.
Optimum, coil rack processes with politef.
The beneficial effect of this utility model is: the dielectric strength of this utility model is high, processing technology is simple relatively.Can effectively solve high voltage and packaging technology troublesome problem that coil can bear 3 minutes 90kV over the ground.
Description of drawings
Fig. 1 is the structural representation that this utility model provides.
Wherein, 1, silicone rubber tube, 2, silicane rubber plate, 3, the silicone rubber protective sleeve, 4, the filament exterior loop, 5, coil rack, 6, cover plate, 7,704 silicon rubber sealants.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is done further explanation.
As shown in Figure 1; After the filament exterior loop 4 that coiling is good puts silicone rubber protective sleeve 3; Put into the wire casing of the coil rack 5 that is processed into politef, insert the outside of filament exterior loop with silicane rubber plate 2, the lead-out wire with coil puts with silicone rubber tube 1 then; Utilize 704 silicon rubber sealants 7 to fill remaining space again, at last lateral cover plate 6 is covered, filament exterior loop 4 just is closed in the wire casing of coil rack 5 fully like this.
