【考案の詳細な説明】産業上の利用分野本考案は、映像機器等に用いる超音波遅延線に
関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to an ultrasonic delay line used in video equipment and the like.

従来例の構成とその問題点従来、この種の超音波遅延線は、第１図および
第２図に示すように構成されている。Conventional configuration and problems thereof Conventionally, this type of ultrasonic delay line has been configured as shown in FIGS. 1 and 2.

る。 That is, the glass delay medium 1 of the ultrasonic delay line
was stored and fixed between an upper case 2 and a lower case 3 by sandwiching them between two cushioning materials 4. In addition, 5 is a lead wire, 6 is a terminal,
7 is an unnecessary reflection absorbing material provided in the glass delay medium.

また厚みも増すという問題があつた。 As described above, the conventional configuration of an ultrasonic delay line has problems such as requiring two pieces of cushioning material 4 to prevent damage to the glass delay medium 1 when dropped, resulting in a large number of parts and an increase in thickness. Ta.

が発生しやすいという問題があつた。 In addition, in this configuration of the ultrasonic delay line, the buffer material 4 inserted between the upper case 2 and the glass delay medium 1 is likely to be misaligned during this series of manufacturing processes, and when the case is sealed, the buffer material 4 is easily misaligned. There was a problem that crowding phenomenon easily occurred.

考案の目的本考案は、上記欠点に鑑み部品点数を減らすと
ともに、作業性を向上させ、かつ、従来より薄い
超音波遅延線を提供するものである。Purpose of the invention In view of the above drawbacks, the present invention reduces the number of parts, improves workability, and provides an ultrasonic delay line that is thinner than the conventional one.

考案の構成この目的を達成するため、本考案は、不要反射
吸収材を、緩衝効果を持たせるため、両面粘着テ

構成である。Structure of the Invention In order to achieve this objective, the present invention has a structure in which an unnecessary reflective absorbing material is attached to one inner wall of the case using double-sided adhesive tape in order to provide a buffering effect.

る。 With this configuration, the number of parts was reduced, and as a result, it became possible to improve workability. In addition, with this configuration, the fall impact performance of the ultrasonic delay line, which is a concern, can be alleviated because there is space other than the bonded inner wall surface, so drop impact energy does not directly propagate from the case, and the bonded The impact energy of a drop from the surface of the case is absorbed by the thickness and viscosity of the double-sided adhesive tape.

同一部品については、同一番号を付与している。DESCRIPTION OF EMBODIMENTS An ultrasonic delay line according to an embodiment of the present invention will be described below with reference to FIGS. 3 and 4. In addition,
Identical parts are given the same number.

Press it lightly to store it. From this point on, the glass delay medium 1 is positioned and fixed to the lower case 3, and the phenomenon of jamming of the conventionally used cushioning material 4 does not occur, making the workability of sealing the upper case 2 much better than before. .

また、従来の２枚の緩衝材に代つて両面粘着テ
ープ８を１枚用いるので全体は従来より薄型化で
きる。 Furthermore, since one double-sided adhesive tape 8 is used in place of the conventional two cushioning materials, the overall structure can be made thinner than the conventional one.

なるという効果が得られる。Effects of the invention As described above, this invention has a structure in which double-sided adhesive tape is attached to the inner wall of the case.
There is no misalignment of the glass delay medium, the double-sided adhesive tape has a shock-absorbing effect, and there is space inside the case, so it is resistant to drop impacts.
It has a very strong structure. Furthermore, since the number of parts is reduced, it is easier to assemble than the conventional assembly method.
