    摘要: A signal transmission terminal (3), a sampling device (23), a battery module (2) and a device are disclosed. The signal transmission terminal (3) is used for the sampling device (23). The sampling device (23) includes a conductive sheet (4). The signal transmission terminal (3) includes a first connecting portion (31), a second connecting portion (32) and a bendable portion (33). The first connecting portion (31) is used for being connected to the conductive sheet (4). The first connecting portion (31) is provided with a raised portion (311). The second connecting portion (32) is connected to the first connecting portion (31) and is used for being connected to a sampling object. The bendable portion (33) is used for being connected to the first connecting portion (31). The bendable portion (33) is configured to press the conductive sheet (4) between the first connecting portion (31) and the bendable portion (33) after being bent. The raised portion (311) is positioned on one side of the bendable portion (33). The bendable portion (33) may be bent towards the raised portion (311), to clamp, along with the raised portion (311), the conductive sheet (4). The above signal transmission terminal (3) can improve connection stability with the conductive sheet (4), such that reliability of sampling precision can be guaranteed.

    摘要: An embodiment of the present application provides a battery pack and a device. The battery pack includes a battery module, a heat exchange member, a flow guide piece and a heat-conducting connecting piece. The battery module includes a plurality of batteries. Each battery is provided with an explosion-proof valve. The heat exchange member includes a heat exchange plate. The heat exchange plate is connected to the plurality of batteries through the heat-conducting connecting piece, and the heat exchange plate at least partially covers each explosion-proof valve. The flow guide piece is arranged between the plurality of batteries and the heat exchange plate, the flow guide piece is provided with a positioning hole penetrating in a height direction of the battery pack, and the positioning hole exposes the corresponding explosion-proof valve. The flow guide piece separates the corresponding explosion-proof valve from the heat-conducting connecting piece. The device includes the battery pack, and the battery pack is configured to provide electric energy. The battery pack provided by the present application ensures that high-temperature and high-pressure gas can successfully break through the explosion-proof valve to damage the heat exchange plate when the battery is subjected to thermal runaway, so that a heat exchange medium can pass through the explosion-proof valve to successfully enter the battery after leaking out from the heat exchange plate, thereby achieving the effect of blocking heat diffusion and effectively preventing the thermal runaway of the battery from spreading.
