Abstract

The utility model relates to an orientation device rays tube and the high voltage cable, comprising a radiator, a tube, filament wires, a tube cap fixed on the tail end of the glass casing of the rays tube, the high voltage cable, a fixing clip, etc., wherein, the core wires in one end of the high voltage cable penetrates into the inside of the glass casing from a tube cap fairlead and are fixed with the two filament wires, which are coated with insulating heat shrinking tubes, and the core wires of the high voltage cable is fixed on the insulating tube cap through the fixing clip. The utility model has the advantages of simple structure, reliable connection of the rays tube and the high voltage cable, and good moistureproof property.

Description

Orientation device rays tube and the high voltage cable

The utility model relates to a kind of improved X-ray orientation device ray tube and high-tension cable thereof.

A kind of direction finder ray tube and high-tension cable thereof are disclosed in CN92235516.9, it is made up of radiator, body, heater lead, insulation pipe cap, binding post, the insulation pipe cap is fixedly mounted on the tail end of ray tube glass bulb, establish two binding posts on the pipe cap, two heater leads are connected on two binding posts, and its high-tension cable directly is connected with binding post.It has not only removed the complicated cable connector, has solved effectively also that the high-tension cable that in the past caused by high heat because of contact punctures and the problem of loose contact.Its weak point is, owing to the outer end that the tie point of ray tube heater lead and high-tension cable is moved to the ray tube glass bulb, has relatively weakened the dielectric strength at contact place, when using in wet environment, may cause the electric leakage problem.

The purpose of this utility model is to provide a kind of contact place high-tension cable that can not only solve effectively to be subjected to high hot breakdown problem, and has enough humidity resistances and prevent the direction finder ray tube and the high-tension cable thereof that leak electricity.

Technical solution of the present utility model is, comprise radiator, body, heater lead, be fixedly mounted on the insulation pipe cap and the high-tension cable of ray tube glass bulb tail end, it is characterized in that, two heart yearns of an end of high-tension cable penetrate the glass bulb the inside from the hole on the insulation pipe cap, directly fixedly connected with two heater leads, and being set with isolating shrinkable tube, the high-tension cable heart yearn is fixed on the insulation pipe cap by clamp.

Advantage of the present utility model is, taked to be connected and to put the structure of isolating shrinkable tube at ray tube glass bulb internal fixation owing to heater lead and high-tension cable, ray tube one work can be heated to heat-shrink tube, it is wrapped on heater lead and the cable core tightly, tie point is also insulated, so not only be connected firmly, prevent cable heated from destroying insulation and breakdown, and because tie point in glass bulb, the humidity resistance height, both made under China's south wet environment and used, and also the electric leakage problem can not take place.

Accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the high-tension cable structural representation

Below in conjunction with accompanying drawing the utility model is described in detail.The utility model is to be improvement on 92235516.9 the utility model patent basis at my application number, and the structure of the radiator 1 of ray tube, body 2, glass bulb 2a, insulation pipe cap 5 remains unchanged here.Insulation pipe cap 5 is to make with 1010 plastics, is adhesively fixed on the glass bulb tail end by silicon rubber 4.The utility model, makes into to connect in glass bulb heater lead 3 and the syndeton of high-tension cable 6 on the insulation pipe cap in order to improve the humidity resistance of ray tube.As shown in FIG., two heart yearn 6a of high-tension cable 6 one ends, the fairlead 10 from insulation pipe cap 5 penetrates glass bulb 2a the inside, directly fixedlys connected with heater lead 3, and present embodiment is fixedly connected by welding.In order to improve insulation property and to prevent that cable is subjected to high thermal conductance to cause insulating barrier and punctures, suit isolating shrinkable tube 11 on heater lead that welds and cable core, the method for suit are earlier heat-shrink tube 11 to be enclosed within on the cable core 6a before welding, after welding is fixing, again heat-shrink tube is pushed inward.Heat-shrink tube 1 is that the heat that produces when working by ray tube itself heats automatically, makes heat-shrink tube thereon fastening.Cable core 6a is fixed on the insulation pipe cap 5 by clamp 7, and it is that a clamp is fixed on the insulation pipe cap by two screws 13 in the present embodiment.For guaranteeing the dielectric strength of two heater leads, also between two heater leads, be provided with insulated isolated device as an example, suit porcelain tube on heater lead 3, isolating shrinkable tube is sleeved on porcelain tube and the cable core 6a, the program of its assembling is, the cover porcelain tube welds then earlier, and the method for suit heat-shrink tube is the same.Be another example as insulated isolated device shown in the figure, it is that insulation board 12 is fixedly mounted in the glass bulb, and insulation board is provided with two rivet holes, and heater lead is drawn from two rivet holes respectively, and is weldingly fixed on the insulation board by rivet hole.What insulation board adopted in the present embodiment is bakelite sheet material, is adhesively fixed in the glass bulb by silicon rubber.Filament wire of drawing from rivet hole and cable core welding also put heat-shrink tube, and heat-shrink tube is set to the root of bakelite plate, and this structure is not only guaranteed the dielectric strength between heater lead, and helps heat radiation.8 is protective covers among the figure, is to be fixed on the insulation pipe cap 5 by screw 9, to improve the safeguard function to the ray tube cathode high voltage.The structure of cable 6 of the present utility model as shown in Figure 2.On the cable core 6b of high-tension cable 6 outer ends, welding is connected the copper sleeve 16 of usefulness with high-tension transformer, and put isolating shrinkable tube 15 in the junction of heart yearn 6b and copper sleeve 16, make its lock ring thereon by heating, put heat-shrink tube 14 at the crust of cable 6 and the intersection of heart yearn, and make its lock ring thereon by heating.The utility model also is fit in the direction finder ray tube of usefulness and the technological transformation of high-tension cable very much.
