ある。[Detailed description of the invention] The present invention relates to a flash discharge tube mounting device, that is, a bushing for fixing a flash discharge tube to a reflector in an electronic flash device or the like. The present invention relates to a flash discharge tube fixing bushing suitable for a light emitting unit configured to apply a trigger pulse through an umbrella.
従来より、反射傘を金属で構成し、この反射傘
と閃光放電管の導電性被膜塗布部分とを接触させ
トリガーパルスを上記反射傘を介して閃光放電管
に供給する技術はよく知られている。 Conventionally, a technique is well known in which a reflector is made of metal, and a trigger pulse is supplied to the flash discharge tube through the reflector by bringing the reflector into contact with the conductive coating portion of the flash discharge tube. .

方が当然小さくなり大きさの点についていえば従
来の他の放電管より非常に有利である。 On the other hand, there is a hermetically sealed flash discharge tube in which both ends of a glass tube are sealed with a metal cap, and an anode and a cathode are formed on the opposing inner surfaces of the metal cap. This hermetic seal type flash discharge tube is constructed as shown in Figure 1, and has a longer distance between the electrodes than conventionally used flash discharge tubes.
The ratio l 0 /l 1 between l 1 and the total length l 0 is small. Therefore,
For example, if you are trying to obtain the same amount of light based on the amount of light, a hermetically sealed flash discharge tube will naturally be smaller, and in terms of size, it is very advantageous over other conventional discharge tubes. be.

とは明らかである。 However, as shown in FIG. 1, in the hermetic type flash discharge tube F, the outer diameter l 2 of the metal caps 3 and 4 forming the main electrodes 1 and 2 to which a relatively high voltage is applied is equal to the glass tube diameter l 2 . 3 , the more conventionally well-known trigger method,
That is, if a trigger band (not shown) is wrapped around a glass tube and a trigger lead wire (not shown) is connected to this trigger band and a trigger pulse is applied, it is natural that the main electrodes 1 and 2 and the trigger band or trigger There is a risk of electrical discharge occurring between the lead wire and the main electrode, trigger band,
I had to be careful about the insulation between the trigger leads. Furthermore, it is clear that even when a trigger method in which a trigger pulse is applied through a reflector is applied to this hermetic type flash discharge tube, the above-mentioned problem of insulation occurs between the reflector and the metal cap.
本考案は、上記絶縁処理を兼ね、かつ反射傘に
放電管を容易に密着させて強固に固着できる取付

る。 The present invention provides a mounting device that also performs the above-mentioned insulation treatment and can easily and firmly attach a discharge tube to a reflector, and has a structure particularly suitable for mounting a hermetic discharge tube. It is.
以下、図面と共に本考案を詳細に説明する。第
２図は、本考案によるブツシングの一実施例を示
す斜視図である。 Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 2 is a perspective view showing an embodiment of the bushing according to the present invention.

している。 As shown in the figure, the bushing body 5 made of an insulating elastic material has insertion holes 6, 7 into which hermetically sealed flash discharge tubes as shown in FIG. It has protrusions 8 and 9 formed on the sides, and a stepped notch 10 for contacting a trigger electrode for applying a trigger pulse.

しその弾性力にて放電管を反射傘を密着する。 It goes without saying that the bushing according to the present invention is made of a material such as rubber that has elasticity and excellent thermal properties. Bushing 5 in this figure 2
is closely attached to the bottom of the reflector, and is shown by the broken line 5a in FIG.
The lower part of the discharge tube is held by the insertion holes 6 and 7, and the reflector is brought into close contact with the discharge tube by its elastic force.

に通して行う。 FIG. 3 shows a perspective view (a) and a cross-sectional view (b) of the hermetic seal system using the bushing of the present invention in a state in which it is fixed to the reflector 11 under the flash discharge tube. For this fixation, first, for example, the lower part of the flash discharge tube is passed through the insertion hole 6, and in this state, the bushing 5 is brought into contact with the reflector 11, the bushing is bent, and the lower part of the discharge tube is further inserted into the holes 11a and 11b of the reflector 11. hole 7
This is done through the following steps.

１１′に密着させられて固着される。 As shown in FIG. 3A, the flash discharge tube F is fixed to the bottom 11' of a reflector 11 made of a conductive material, for example, while being constantly pushed in the direction of arrow A by the elastic force of the bushing 5. Therefore, as shown in FIG. 3B, the flash discharge tube F is securely and firmly attached to the bottom surface 11' of the reflector 11.

る。 Further, the main electrodes 1 and 2 are held in contact with each other by the protrusions 8 and 9, and the thickness l4 of the bushing in this part including the protrusions 8 and 9 is thicker than the thickness l5 of the other parts. That is, the distance between the reflective umbrella 11 and the main electrodes 1, 2 is forcibly maintained at the thickness l4 , and the insulation effect between the conductive reflective umbrella 11 and the main electrodes 1, 2 becomes very large. In addition, as shown in Figures 2 and 3, the insertion hole 6,
By configuring the protrusions 8 and 9 only around the flash discharge tube F, the holding strength of the flash discharge tube F can be strengthened.
尚、反射傘１１と主電極１，２間の距離だけを

ある。 Incidentally, if only the distance between the reflector 11 and the main electrodes 1 and 2 is considered, the structure can be simplified by increasing the overall thickness of the bushing 5 without the need for the protrusions 8 and 9. This will reduce the amount of materials needed for manufacturing and the installation of the flash tube.
However, the bushing shown in FIG. 2 according to the present invention has a very high practical value from this point of view.

付作業を容易に行う点で効果を発揮する。 Further, as shown in FIG. 3A, the groove 10 allows the bottom surface 11' of the reflector 11 to be exposed without being covered by the bushing, so that a trigger electrode (not shown) can easily be brought into contact therewith. This groove 10 does not necessarily have to be formed; for example, if the trigger electrode is brought into contact with the side of the reflector 11 or with the end of the bottom surface, the groove 10 can be formed as shown in FIG. It is not necessary to configure the grooves as shown in FIG. Furthermore, forming the groove 10 as shown in FIGS. 2 and 3 weakens the elastic force in the center of the bushing 5, which is effective in facilitating the attachment of the bushing 5 to the reflector 11.

The flash discharge tube can be brought into close contact with the bottom surface of the reflector, and the distance between the main electrode of the flash discharge tube and the reflector can be forcibly maintained at an arbitrary distance or more by the protrusion. A structure suitable for forming a light emitting part by attaching a flash discharge tube to a reflector to which a trigger pulse is applied can be obtained. Note that the present invention can also be applied to the installation of discharge tubes other than flash discharge tubes. Further, grooves may be provided on the surface of the umbrella to ensure the fixation of the discharge tube.
