본 고안은 음극선관용 방폭밴드에 관한 것으로서, 고인장력에 의해서도 그 결속상태를 유지할 수 있도록 개량된 것에 관한 것이다.The present invention relates to an explosion-proof band for a cathode ray tube, and to an improvement to maintain the binding state even by high tensile force.

음극선관용 방폭밴드의 패널의 측면부위를 고인장력으로서 조이도록 하는 것으로서 고진공상태를 유지하고 있는 음극선관의 균열과, 균열 확산, 그리고 푹축현상을 방지하고 있는 것이다. 이러한 방폭밴드는 제 1 도, 제 2 도에 도시된 바와같이 이음단부(12a)(12b)가 포개어진채 저항용접으로써 결속되어 있거나, 제 2 도에 도시된 바와같이 이음단부(12a)(12b)를 맞대어 놓은 상태에서 별도의 이음보강판(11b)을 덧붙여서 저항용접으로써 연결되도록 하고 있다.By tightening the side surface of the panel of the explosion-proof band for cathode ray tubes with high tensile force, it prevents the cracking, crack spreading, and pinching of the cathode ray tube maintained in a high vacuum state. Such explosion-proof bands are bound by resistance welding with the joint ends 12a and 12b overlapped as shown in FIGS. 1 and 2, or the joint ends 12a and 12b as shown in FIG. In the state of facing each other by adding a separate joint reinforcing plate (11b) to be connected by resistance welding.

그러나 이러한 취약한 결합구조는 방폭밴드에 가해지는 고인장력에 의해 이내에 파괴되는데 특히 용접부위에서의 찢어짐이 발생되어 절단되고 마는 것이다.However, this fragile coupling structure is broken within by the high tensile force applied to the explosion-proof band, in particular, tearing occurs at the welded area and is cut off.

본 고안은 매우 견고한 구조로서 매우 높은 내인장강도를 지니도록 이음부위가 개선된 음극선관용 방폭밴드를 제공함에 그 목적이 있다.The object of the present invention is to provide an explosion-proof band for cathode ray tubes with improved joints to have a very high tensile strength as a very solid structure.

상기의 목적을 달성하기 위하여 본 고안은, 음극선관의 패널 외측면 둘레에 고인장력으로써 장착되는 음극선관용 방폭밴드에 있어서, 일측이음단부에는 걸림돌기를 돌출형성하고, 타측 이음단부에는 상기 걸림돌기가 밀착되게 끼워질 수 있는 걸림구멍을 형성하여, 상기 양이음단부를 포개어 접속시키는 한편, 별도의 보강판을 마련하여 상기 양이음단부의 이음부위에 장착하여서 상기 보강판이 상기 양이음단부와 직접 용접되도록 하는점에 그 특징이 있다.In order to achieve the above object, the present invention, in the explosion-proof band for the cathode ray tube is mounted with a high tensile force around the outer surface of the cathode ray tube, one end portion protrudes to form a projection, and the other end portion is in close contact with the engaging projection Forming a hooking hole to be fitted, and overlapping the positive joint end portion, while providing a separate reinforcement plate to be mounted on the joint portion of the positive joint end portion so that the reinforcement plate is directly welded to the positive joint end portion Has its features.

이하 첨부된 도면에 예시된 본 고안의 한 실시예를 상세히 설명한다.Hereinafter, an embodiment of the present invention illustrated in the accompanying drawings will be described in detail.

제 4 도에 도시된 바와같이, 서로 면 접촉되는 부위가 형행절곡된 이음부위(10c)의 양 이음단부(12c)(12c)에는 걸림돌기(13c)와 이에 대응되는 걸림구멍(14c)이 형성되고, 그 상부에는 상기 이음단부(12c)(12c)간의 절곡상태에 대응되는 형태로 절곡된 별도의 보강판(11c)이 마련된다.As shown in FIG. 4, the engaging projections 13c and the corresponding engaging holes 14c are formed in both of the joint portions 12c and 12c of the joint portion 10c where the portions in contact with each other are bent. The upper part is provided with a separate reinforcing plate 11c bent in a form corresponding to the bent state between the joint ends 12c and 12c.

이러한 구조의 이음부위(10c)는 제 5 도에 도시된 바와같이 결합되는데, 상기 걸림구멍(14c)에 걸림돌기(13c)가 밀착되게 끼워지도록 상기 양 이음단부(12c)(12c)가 포개지고, 그 상부로 부터 상기 보강판(11c)이 덧씌워진 채 점용접된다. 이때의 용접부위를 살펴보면, 도면에서 중앙으로 부터 우측 이음단부(12c)의 걸림구멍(14c)에 끼워진 좌측 이음단부(12c)의 걸림돌기(13c)가 그 상부의 보강판(11c)과 용접되며, 그 양측으로는 위에서부터 보강판(11c), 우측 이음단부(12c), 좌측 이음단부(12c)의 순으로 한꺼번에 저항 용접되며, 그 양외과측으로는 각측의 이음단부(12c)(12c)와 보강판(11c)이 각각 점용접된다.The joint portion 10c of this structure is coupled as shown in FIG. 5, and the two joint ends 12c and 12c are overlapped so that the locking projection 13c is fitted in close contact with the locking hole 14c. From the top, the reinforcing plate 11c is welded overlaid. Looking at the welding portion at this time, the locking projection 13c of the left joint end 12c fitted into the engaging hole 14c of the right joint end 12c from the center in the drawing is welded with the reinforcing plate 11c of the upper portion. On both sides thereof, resistance welding is carried out at the same time from the top in the order of the reinforcing plate 11c, the right joint end 12c, and the left joint end 12c, and on both sides the joint ends 12c and 12c of each side. The reinforcing plate 11c is spot welded, respectively.

이와같은 구조의 이음부위는 점용접부가 많기 때문에 인장강도가 전적으로 증가도는 것이 아니고, 보강판과 양이음단부간의 용접관계가 번갈아가면서 이루어져 능률적으로 형성되어 있기 때문인데, 더우기 걸림구멍을 관통한 걸림돌기가 상기 보강판과 직접중점되는 관계로 이에의한 버팀효과가 크게 증가되어 있기 때문인것이다.Since the joints of such a structure have many spot welding parts, the tensile strength does not increase entirely, but because the welding relationship between the reinforcing plate and the positive joint ends is alternately formed, it is efficiently formed. This is because the brace effect is greatly increased because the group is directly focused on the reinforcing plate.

이상에서와 같이 본 고안은 이음부위의 강도가 매우 크게 보강됨으로써 종래와 같은 파단현상이 전무하게 되는데, 제품의 신뢰성, 안정성을 도모함은 물론 제품의 불량화에 따른 생산비 손실을 저감시킬수 있는 효과를 가지는 것이다.As described above, the present invention has no breakage phenomenon as in the prior art by reinforcing the strength of the joint portion very largely, and has the effect of reducing the production cost loss due to product reliability and stability as well as product defects. will be.
