An isolator for an aircraft fuel tank configured to separate an electrically conductive internal panel of the fuel tank from an electrically conductive pipe that passes through the panel. The isolator includes: a plurality of first attachment points for attaching the isolator to the panel, a plurality of second attachment points for attaching the isolator to the pipe, and an aperture defined by an outer wall and extending from a first side of the isolator to a second side of the isolator. The aperture is configured to receive the pipe in use, wherein the isolator is formed of a non-electrically conductive material.

The present disclosure provides a heat exchange pipe joint and a battery pack. The heat exchange pipe joint is fixedly installed to an installation plate. The heat exchange pipe joint includes a first pipe and a second pipe that are separately formed and in communication with each other. The first pipe is detachably connected to a second side of the installation plate, and the second pipe is detachably connected to a first side of the installation plate. When the heat exchange pipe joint of the present disclosure is applied to the battery pack, the heat exchange pipe joint in a split-structure requires a small operation space for detachment and installation. In this case, a process of taking out the entire heat exchange pipe joint from the case can be avoided, so that the battery module and other components inside the case do not interfere with the detachment and installation of the heat exchange pipe joint. In this way, the detachment and installation of the heat exchange pipe joint can be easy and convenient, thereby facilitating the reparation process thereof.
