Abstract: A signal transmission terminal, a sampling device, a battery module and a device are disclosed. The signal transmission terminal is used for the sampling device. The sampling device includes a conductive sheet. The signal transmission terminal includes a first connecting portion, a second connecting portion and a bendable portion. The first connecting portion is used for being connected to the conductive sheet and is provided with a raised portion. The second connecting portion is connected to the first connecting portion and is used for being connected to a sampling object. The bendable portion is used for being connected to the first connecting portion. The bendable portion is configured to press the conductive sheet between the first connecting portion and the bendable portion after being bent. The above signal transmission terminal can improve connection stability with the conductive sheet, such that reliability of sampling precision can be guaranteed.
