Implosion prevention band for CRT

本发明涉及一种用于CRT(10)的防爆带(30)。CRT包括抽空的外壳(12)，其具有荫罩(35)以及对应的荧光屏面板(14)，面板具有与锥体(18)相连的侧壁(26)。荧光屏面板和侧壁形成了外角部表面和周边的内倒圆半径(38)。防爆带围绕并紧密地设置在荧光屏面板的外角部表面的至少一个边缘处。带沿着侧壁的外表面延伸，使得带的宽度处于荧光屏面板的内倒圆半径处或其附近。带处于荧光屏面板的内倒圆半径处或其附近。带处于张紧状态，产生了通过荧光屏面板的角部并主要位于倒圆半径的附近处的径向向内的作用力分量，从而产生了用于CRT的较高程度的防爆性。 The present invention relates to an implosion prevention band for a CRT comprising an evacuated envelope having a mask and corresponding faceplate panel with sidewalls joined to a funnel. The faceplate panel and sidewalls form external corner surfaces and a peripheral inside blend radius. An implosion prevention band surrounds and closely hugs at least an edge of the external corner surfaces of the faceplate panel. The band extends along the exterior surface of the sidewall such that the width of the band is at or near the inside blend radius of the faceplate panel. The band is under tension to produce radially inwardly directed force components through the corners of the faceplate panel and primarily near the blend radius to produce a high degree of implosion protection for the CRT.
