参见图 5 , 作为一种实施方式， 还可以将绝缘层的第二部分 32设置成与 电路板 1表面贴合， 这样， 第二部分 32直接贴合在电路板 1的过孔上， 直接 与连接器的第二端和电路板 1 的连接处接触， 从而能够更加有效地防止外部 液体进入电路板上的过孔， 避免造成过孔处的连接器针短路。  Referring to FIG. 5, as an embodiment, the second portion 32 of the insulating layer may be disposed to be in contact with the surface of the circuit board 1. Thus, the second portion 32 directly fits on the via hole of the circuit board 1, directly The second end of the connector is in contact with the junction of the circuit board 1, so that external liquid can be prevented from entering the via hole on the circuit board more effectively, and the connector pin at the via hole can be prevented from being short-circuited.

参见图 6, 对于与用户设备连接的连接器第二端， 由于该侧连接器直接 面对用户的插拔等操作， 而第二端的中部分针 2为连接电源的电源针 21 , — 旦这些电源针 21接触到液体， 则容易发生短路打火。 由于连接器连接用户设 备时不需要使用电源针， 因此， 可以将电源针 21设置在绝缘层中， 如果电源 针 21靠近第一部分 31 , 则将该电源针 21截去部分， 使剩余部分埋在绝缘层 的第一部分 31中， 如果电源针 21穿过绝缘层的第二部分 32, 则将其截取部 分， 使剩余部分埋在绝缘层的第二部分 32中， 从而能够避免电源针 21伸出 绝缘体外接触到液体而短路打火。  Referring to FIG. 6, for the second end of the connector connected to the user equipment, since the side connector directly faces the user's insertion and removal operations, and the middle portion of the second end pin 2 is the power supply pin 21 connected to the power source, these are When the power pin 21 is in contact with the liquid, short-circuit ignition is liable to occur. Since the power supply pin is not required when the connector is connected to the user equipment, the power pin 21 can be placed in the insulating layer. If the power pin 21 is close to the first portion 31, the power pin 21 is cut off, and the remaining portion is buried. In the first portion 31 of the insulating layer, if the power pin 21 passes through the second portion 32 of the insulating layer, the portion is cut out, and the remaining portion is buried in the second portion 32 of the insulating layer, thereby preventing the power pin 21 from sticking out The insulator is exposed to liquid outside the body and short-circuited.

为了进一步提高安全性， 可以在绝缘层中与电路板 1平行方向上设置至 少一个排水槽 33 , 其中， 排水槽 33与第一部分 31、 第二部分 32以及电路板 组成的封闭空间相通， 从而使封闭空间内可能存在的少量水得以排出。 通过 采用上述设置，即便电路板 1与绝缘层的第二部分 32由于某种特殊原因而不 能完全贴紧， 或者在特定情况下出现非常少量的积水， 液体也可从排水槽 33 排除。 由于设备的背板在使用时通常是垂直放置， 因此可在与电路板 1平行 的方向上设置排水槽 33。 背板垂直放置时， 积水通常存在与封闭空间的最底 部， 因此， 相应的， 可以将排水槽 33设置在绝缘层垂直放置时的最下方， 参 见图 7, 这样， 当背板垂直放置时， 排水槽 33的方向也是垂直的， 从而能够 使封闭空间内的少量积水得以排出。 In order to further improve the safety, at least one drain groove 33 may be disposed in the insulating layer in parallel with the circuit board 1, wherein the drain groove 33 communicates with the closed space composed of the first portion 31, the second portion 32 and the circuit board, thereby A small amount of water that may be present in the enclosed space can be discharged. By adopting the above arrangement, even if the circuit board 1 and the second portion 32 of the insulating layer are not completely adhered to each other for some special reason, or a very small amount of accumulated water appears in a specific case, the liquid can be removed from the drain groove 33. Since the backplane of the device is usually placed vertically when used, it can be parallel to the board 1. A drain groove 33 is provided in the direction. When the backing plate is placed vertically, the accumulated water usually exists at the bottom of the closed space, and accordingly, the drain groove 33 can be disposed at the bottom of the insulating layer when it is vertically placed, see Fig. 7, so that when the backing plate is vertically placed The direction of the drain groove 33 is also vertical, so that a small amount of accumulated water in the closed space can be discharged.
