• ACID LIQUID LEAK SENSOR
  申请人：Origin Electric Company Ltd

  公开号：EP1722217A1

  公开（公告）日：2006-11-15

  An acid liquid leakage sensor is capable of quickly detecting liquid leakage from a device, such as a battery or the like, in which acid liquid is charged, and this acid liquid leakage sensor includes a first conductive member, a second conductive member, and an electrically insulating material which establishes an electrically insulating state between these first and second conductive members. The electrically insulating material includes a macromolecular compound having a basic functional group, and is one whose electrical insulation characteristic or high resistance characteristic decreases upon reaction with an acid liquid; so that it is possible to detect leakage of acid liquid such as battery fluid, by detecting the change of conductive state between the first conductive member and the second conductive member which accompanies the decrease of the electrical insulation characteristic or high resistance characteristic of the electrically insulating material, when acid liquid leaks out and drips down the electrically insulating material.

  一种酸性液体泄漏传感器能够快速检测充有酸性液体的设备（如电池或类似设备）中的液体泄漏，这种酸性液体泄漏传感器包括第一导电部件、第二导电部件和在这些第一和第二导电部件之间建立电绝缘状态的电绝缘材料。电绝缘材料包括具有碱性官能团的大分子化合物，与酸性液体反应后，其电绝缘特性或高电阻特性会降低；因此，当酸性液体渗出并滴落到电绝缘材料上时，通过检测第一导电部件和第二导电部件之间的导电状态变化（伴随着电绝缘材料的电绝缘特性或高电阻特性的降低），可以检测到酸性液体（如电池液）的渗漏。

  A liquid medicine injection device (1) has an upper member (3), a lower member (2), and a sealing member (4) accommodated between both members. The lower member has a part (22a), for pressing a peripheral portion of the sealing member, which is formed of an upper surface of an annular wall part (22) and an annular edge part (25) formed at an inner side of the part (22a) for pressing the peripheral portion of the sealing member. An upper-surface side of a flange part (42) of the sealing member is pressed by the upper member, and an outer-edge portion of a lower-surface side of the flange part is pressed by the part (22a) for pressing the peripheral portion of the sealing member with the annular edge part (25) in penetration into an inner-edge portion of the lower-surface side of the flange part. As a result, there is a decrease of a skirt-shaped projected part (43) of the sealing member, and an outer peripheral surface of the lower end of a part (41b) to be inserted into the lower member closely contacts an inner surface of the annular wall part.
