[0031] like Figures 1 to 6 As shown, a connector of a low-voltage power cable comprises: a fixing column 1, a through hole 102 is provided inside the fixing column 1, the through hole 102 passes through the fixing column 1, and a connecting block 101 is provided inside the through hole 102; a plug-in component 4 is arranged inside the fixing column 1 for connecting the cable; a fixing component 2 is arranged inside the fixing column 1 for fixing the position of the plug-in component 4; a connecting component 3 is arranged outside the fixing component 2 for fixing the position of the cable. Specifically, when in use, the plug-in component 4 is first connected to the cable, and after the connection is completed, the plug-in component 4 is inserted into the fixing column 1 to connect the cable, and after the connection is completed, the plug-in component 4 is fixed by the fixing component 2 to avoid separation of the plug-in component 4 from the fixing column 1 during use, thereby ensuring stability during connection, and while the fixing component 2 fixes the plug-in component 4, the cable is fixed to the fixing component 2 by the connecting component 3, so that the cable is fixed relative to the fixing component 2, thereby ensuring stability during use of the cable.

[0032] like Figures 1 to 6 As shown, limiting grooves 103 are further provided at both ends of the fixing column 1, and fixing grooves 104 are provided at both ends of the connecting block 101.

[0033] like Figures 1 to 6 As shown, plug-in blocks 105 are provided at both ends of the connection block 101 . Specifically, the plug-in blocks 105 locate the position of the plug-in connector 4 to ensure the accuracy of the position when the plug-in connector 4 is connected to the connection block 101 .

[0034] like Figures 1 to 6As shown, the connectors 4 are distributed at both ends of the connection block 101, and the connectors 4 are conical in shape. The connectors 4 and the ends relative to the connection block 101 are provided with plug-in grooves 402, and the plug-in grooves 402 are adapted to the plug-in block 105. The opposite side of the connector 4 is provided with plug-in columns 401, and the plug-in columns 401 are provided with metal columns 403 at the ends relative to the connection block 101, and the metal columns 403 are adapted to the fixed tube 106. Specifically, when connecting the cables, the wires of the cables are first connected to the metal columns 403 respectively, and the metal columns 403 are made of metal. After the cable connection is completed, the plug-in columns 401 are inserted into the through holes 102, and the plug-in grooves 402 are aligned with the plug-in block 105 while being inserted, so that the metal columns 403 can be inserted into the fixed tube 106, thereby conducting the current.

[0035] More specifically, the cables to be connected are fixed by the connector 4, and the cables are conducted by the connecting block 101. The connecting block 105 cooperates with the connecting slot 402 to fix the connection angle of the connecting column 401, so that the metal columns 403 on both sides of the connecting block 101 can correspond one by one, avoiding the short circuit caused by the staggered metal columns 403 during connection. The number of metal columns 403 can be selected according to the number of cable cores.
