The invention provides a low voltage quick connector comprising a connecting bar (1) which is used for being connected with a low voltage cable copper terminal; and a quick connector (2) which is usedfor being connected with a copper bar. One end of the quick connector (2) is connected with the connecting bar (1), and the other end is provided with an opening and forms a clamping groove (20) fromthe opening to the connecting bar (1). The quick connector (2) comprises a first clamping part (21) and a second clamping part (22) which are identical in structure and symmetrically arranged according to the clamping groove (20). One surface, which faces the second clamping part (22), of the first clamping part (21) is provided with multiple first contactor grooves (214). One surface, which faces the first clamping part (21), of the second clamping part (22) is provided with multiple second contactor grooves (224) which are matched with the first contactor grooves (214). Plugging connectionof the copper bar can be quickly realized, and the flow capacity of 2000 amperes can also be met so that the work efficiency can be enhanced, the power outage time can be reduced and the low voltage quick connector is significant for improving the bypass work.
