An elastic member 48 is provided between the clamping plate 1 47 and the clamping plate 2 49. The elastic member 48 is a spring material structure. The elastic member 48 is used to provide a clamping force to ensure that the cable is stably clamped during the assembly process. A guide groove is provided inside the conveying shell 5. The guide groove is used to guide the correct position of the cable to ensure the accuracy of assembly. In actual use, the motor 36 is first started by control. The motor 36 drives the terminals on the conveyor belt through the roller 37 for transportation. When each terminal falls into the conveying channel in turn, at this time, the cylinder 2 38 is driven to run. The cylinder 2 38 drives the positioning plate to push the terminal to the cylinder 39.
