    • Disclosed herein is a case sealing structure and an assembling method therefor which can realize the dustproof and waterproof performances of the case with a simple configuration and reliability. The case sealing structure includes an upper case having a top portion and a side portion to define a lower opening; a lower case having a bottom portion and a side portion to define an upper opening, the lower case being engaged with the upper case with the lower opening and the upper opening facing each other; and an elastic sealing member having a top portion and a side portion, the sealing member being stored in the upper and lower cases. The inner surface of the side portion of the sealing member is formed with a groove engaging with the outer periphery of a printed board. The sealing member is held between the outer periphery of the printed board engaging with the groove and the inner surface of the side portion of the upper case.
    • 这里公开了一种壳体密封结构及其组装方法,其可以以简单的结构和可靠性实现壳体的防尘和防水性能。 壳体密封结构包括具有顶部和侧部以限定下开口的上壳体; 下壳体具有底部和侧部以限定上部开口,所述下部壳体与所述上部壳体接合,所述下部开口和所述上部开口彼此面对; 以及具有顶部和侧部的弹性密封构件,所述密封构件被储存在所述上部和下部壳体中。 密封构件的侧部的内表面形成有与印刷板的外周接合的凹槽。 密封构件被保持在印刷板的与外周边缘凹槽的外周面和上壳体的侧部的内表面之间。
