본 고안은 음극선관의 보강밴드에 관한 것이다.The present invention relates to a reinforcing band of a cathode ray tube.
일반적으로 음극선관의 패널부와 펀넬부가 봉착되는 부위에는 폭발을 막아주기 위한 방폭밴드가 둘러쳐져서 긴밀하게 조여 붙여지게 된다.In general, the explosion-proof band to prevent the explosion is enclosed tightly attached to the panel portion and the funnel portion of the cathode ray tube is sealed.
그리고 음극선관의 네모서리에 위치하는 방폭밴드로는 캐비넷과 음극선관을 연결하기 위한 러그가 부착된다.The explosion-proof band located at the four corners of the cathode ray tube is attached with a lug for connecting the cabinet and the cathode ray tube.
전기한 바와같이 음극선관에 감아 붙여지는 방폭밴드는 음극선관 외면의 구조적인 특징에 기인하여 전면이 음극선관에 접촉되지 않게 된다.As described above, the explosion-proof band wound around the cathode ray tube does not come into contact with the cathode ray tube due to the structural features of the outer surface of the cathode ray tube.
즉, 제 1 도에 도시한 바와같이 패널부(1)과 펀넬부(2)의 형상이 경사져있음에 기인하여 띠상의 방폭밴드체(3)과의 사이에는 간격(P)가 형성된다.That is, as shown in FIG. 1, the space | interval P is formed between the strip | belt-shaped explosion-proof band body 3 because the shape of the panel part 1 and the funnel part 2 is inclined.
방폭밴드체(3)에 의한 조임력은 음극선관의 주위로 균일하게 그리고 넓은 면적에 분포되야 바람직스러운 것인데, 전술한 바와같이 간격(P)가 형성됨에 따라 방폭밴드체(3)의 극히 일부분이 음극선관에 접촉되어 방폭밴드의 제기능을 다하지 못하게 된다.The tightening force by the explosion-proof band body 3 is preferably distributed uniformly and in a large area around the cathode ray tube. As described above, as a gap P is formed, only a part of the explosion-proof band body 3 is negative. Contact with the tube will prevent the explosion-proof band from functioning.
본 고안은 종래 방폭밴드가 갖는 문제점을 보완코자 안출한 것으로서, 방폭효율을 증대 가능케하는 음극선관의 보강밴드를 제공함에 그 목적이 있다.The present invention has been made to solve the problems of the conventional explosion-proof band, and the object is to provide a reinforcing band of the cathode ray tube to increase the explosion-proof efficiency.
이에 따라 본 고안은 방폭밴드의 비 접촉으로 발생되는 공간부위에 음극선관의 패널면과 동일 곡률을 이루는 보강밴드를 형성하여 이루어짐을 특징으로 한다.Accordingly, the present invention is characterized in that it is made by forming a reinforcement band having the same curvature as the panel surface of the cathode ray tube in the space portion generated by the non-contact of the explosion-proof band.
이하 본 고안을 첨부한 도면에 의거하여 첨부도면 제 2 내지 제 3 도를 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings 2 to 3 based on the accompanying drawings.
제 2 도는 본 고안의 보강밴드와 방폭밴드의 상호관계를 나타내는 도면으로서, 제 1 도와 동일기능을 갖는 부분은 동일 부호로 지칭한다.2 is a view showing the mutual relationship between the reinforcing band and the explosion-proof band of the present invention, the parts having the same function as the first and the same reference numerals.
지칭된 부호(4)는 보강 밴드체로서, 패널부(1)의 접촉면과 동일 곡률을 이루는 접촉면(5)가 형성되어 있다.Reference numeral 4 denotes a reinforcing band body in which a contact surface 5 which has the same curvature as the contact surface of the panel portion 1 is formed.
그리고, 접촉면(5)에는 수직연장부(6)이 연장 형성되어 있으며, 이 수직연장부(6)에는 대향판(7)이 수직설치되어 홈(8)이 형성되어 있다.The vertical extension part 6 is extended in the contact surface 5, and the vertical extension part 6 is provided with the opposing board 7 in the vertical direction, and the groove 8 is formed.
이 홈(8)에 방폭밴드체(3)이 삽입되어 러그(9)에 의해 캐비넷(도시생략)에 지지된다.The explosion-proof band body 3 is inserted into this groove | channel 8, and is supported by the cabinet (not shown) by the lug 9.
제 3 도는 본 고안의 설치상태를 나타내는 도면으로서, 패널부(1)과 펀넬부(2)의 봉착위에는 방폭밴드체(3)이 감아 붙여져 조여져 있으며, 방폭밴드체(3)과 패널부(1)과의 사이에 보강밴드체(4)의 접촉면(5)가 삽입되어 있다.3 is a view showing the installation state of the present invention, the explosion-proof band body (3) is wound around and tightened on the sealing of the panel portion (1) and the funnel portion (2), the explosion-proof band body (3) and the panel portion (1). The contact surface 5 of the reinforcing band body 4 is inserted between the back and bottom.
즉, 제 1 도에 표시된 간격(P)내로 접촉면(5)가 삽입되어 패널부(1)의 외면과 밀착되어 있다.That is, the contact surface 5 is inserted into the space P shown in FIG. 1 and is in close contact with the outer surface of the panel portion 1.
그리고, 홈(8)에는 방폭밴드체(3)이 끼워져 결국 방폭밴드체(3)의 조임력이 패널부(1)에 넓게 작용하게 된다.And the explosion-proof band body 3 is fitted in the groove | channel 8, and the tightening force of the explosion-proof band body 3 acts on the panel part 1 widely.
따라서, 음극선관과 방폭밴드체의 접촉면적이 넓어져 방폭효과를 높일 수 있다.Therefore, the contact area between the cathode ray tube and the explosion-proof band body can be increased to increase the explosion-proof effect.
그리고, 보강밴드체(4)의 접촉면(5)가 패널부(1)에 접촉되어 있음에 기인하여 음극선관 외부에 발생하는 정전기가 이를 통하여 셋트 내부로 흘러 들어가게 된다.Then, due to the contact surface 5 of the reinforcing band body 4 is in contact with the panel portion 1, the static electricity generated outside the cathode ray tube flows into the set through this.
이상과 같이 본 고안은 방폭밴드의 접촉면적을 증대시켜 방폭효율을 향상시킴과 아울러 정전기를 제거할 수 있어 소비자의 안전을 도모할 수 있게 된다.As described above, the present invention can improve the explosion-proof efficiency by increasing the contact area of the explosion-proof band, and can also eliminate static electricity, thereby promoting consumer safety.
