Description

The power supply connecting device of dual ended gas discharge lamp

Technical field

What the present invention relates to a kind of gaseous discharge lamp and power supply is connected particularly a kind of power supply connecting device of dual ended gas discharge lamp.

Background technology

Patent No. CN201020273628.6 " plant illumination is used high-power gas charging lamp " is connected with power supply with the screw thread of lamp holder end, though easy to use; But the working temperature of gaseous discharge lamp is high; After working long hours, lamp holder is prone to the heating blackening and also is prone to become flexible, and uses dangerous.

Patent No. CN201020271581.X " both-end high-power high voltage sodium vapor lamp ", though also disclose a kind of and jockey power supply, the light emitting source two ends are connected with molybdenum rod; Molybdenum sheet is arranged on the glass bulb two ends and flattens hermetic seal place, is connected with the lead of being processed by the multiply wire guide of drawing with molybdenum rod respectively, because of flattening hermetic seal place that is connected with power supply is that the glass workpiece coefficient of heat conduction is low; Mechanical strength is low; Long term high temperature work rearward end Glass breadks easily splits, and directly is electrically connected with power supply with drawing lead, and single bundle lead contact-making surface is little, capacitance is little; Be prone to diffusing, easily broken, yielding, connect not firm, use is dangerous.

Summary of the invention

Technical problem to be solved by this invention is: the power supply connecting device that a kind of dual ended gas discharge lamp is provided; It is simple in structure, volume is little, and long term high temperature work discharge lamp two ends lamp holder can not generate heat, is out of shape, becomes flexible, and is safe and reliable; And mechanical strength is high, and electric property is better.

The present invention addresses the above problem the technical scheme that is adopted: the power supply connecting device of dual ended gas discharge lamp; Comprise the fixing molybdenum sheet of lamp tube ends flattening hermetic seal place; Molybdenum sheet respectively with molybdenum rod with draw lead and be connected; The said wire clamp of drawing is held in formation lead-out wire intermediate plate between intermediate plate, the also fixing respectively porcelain head of said lamp tube ends, and said lead-out wire intermediate plate is fixed on the porcelain head.

Compared with prior art, the invention has the advantages that: draw lead in the power supply connecting device of dual ended gas discharge lamp, being clamped in becomes holistic conductor strip in the stainless steel metal sheet; Be convenient to operation and directly the lead-out wire intermediate plate injected in the supply socket, electric interface is big, significantly reduces the heating phenomenon; And the lead-out wire intermediate plate other end is fixedly mounted on in the high insulation porcelain head of heatproof moisture-proof, dielectric strength; Have in the porcelain head with lamp tube ends and flatten the groove that hermetic seal place is complementary, flatten hermetic seal and embed integrant power supply connecting device in groove, mechanical strength is high; Porcelain head surface configuration rule is smooth; Make things convenient for the glass part of installing and using and protect lamp tube ends of gaseous discharge lamp not easily broken, prolonged the useful life of discharge lamp greatly, improve former power supply connecting device again and be prone to the drawback that heating, distortion, Glass breadks easily are split; And good electric property is used safety and reliability.

Embodiment

Below in conjunction with accompanying drawing embodiments of the invention are described in further detail.

Lead-out wire intermediate plate 10 is processed the intermediate plate 8 that there is impression on two surfaces by stainless steel substrates; Clamping is drawn the integral body that the outer end of lead 9 is fixed into and is constituted in the gap therebetween; Firm for connecting, draw lead and can not move, also add spot welding again at the intermediate plate of drawing the lead outer surface 8 places; Make and draw lead and be completely fixed on the intermediate plate, like Fig. 1, Fig. 3, shown in Figure 5.

Porcelain head 7 is processed by heatproof, moisture-proof, insulating material that dielectric strength is high; Short groove 7-2 is arranged on the left side vertical surface of porcelain head; On the right surface long recess 7-1 is arranged; Two through wires hole 7-4 are arranged on the bottom surface vertical plane of long recess and communicate with short groove 7-2, upper surface has low groove 7-3, like Fig. 1, Fig. 2, shown in Figure 4.

The width of weak point, low groove 7-2,7-3 and the thickness of intermediate plate 8 are complementary.

The two ends of the electric arc tube 2 of elongated tubular; Pass the supported hole of disc supporting slice 3 centres respectively; Weld an end of nickel wire 4 on the electric arc tube 2 two ends outer surfaces respectively, the other end of nickel wire is welded on the molybdenum rod 5, and an end of molybdenum rod 5 is fixed on the inwall of electric arc tube 2 terminations; The other end of molybdenum rod 5 is welded on the molybdenum sheet 6, also welds the inner of drawing lead 9 on the molybdenum sheet.

The electric arc tube that assembles 2 is put into fluorescent tube 1, and the both sides symmetry is installed, and supporting slice 3 is slidingly matched with fluorescent tube 1 inwall gap.

The cross section that hermetic seal 1-1 place is flattened at fluorescent tube 1 two ends is an I shape, the check road that increases friction and intensity is arranged on two surfaces of flattening place, and make molybdenum sheet 6 place flattening place; Draw the outer end of lead 9 and pass long and short groove 7-1,7-2 and a through wires hole 7-4 on the porcelain head 7, and extend to outside the porcelain head, insert integrant lead-out wire intermediate plate in the gap of intermediate plate 8 again; The upper end of lead-out wire intermediate plate 10 embeds in the low groove 7-3 of porcelain head, the inner embedding in the short groove 7-2, and the outward flange that flattens hermetic seal 1-1 embeds in the porcelain head long recess 7-1; And pour in the long recess with binding agent; Porcelain head 7 and fluorescent tube 1 are fixed into integral body, fluorescent tube can not become flexible, as shown in Figure 5.

Fluorescent tube 1 directly utilizes two ends, and by the power supply connecting device that porcelain head 7 and lead-out wire intermediate plate 10 constitute, the clip place that laterally embeds in the supply socket uses.
