Description

Technical Field

[0001] The utility model relates to a terminal cutting device for a connector, belonging to the technical field of connectors. Background Art

[0002] At present, in the connector assembly process, it is necessary to cut a whole terminal from the reel into pieces of terminals of different lengths, and then assemble the finished products. However, during use, the existing terminal cutting device for connectors is often not convenient for fast fixing and disassembly of the terminal strip reel, and the unwinding mechanism for driving the terminal strip is often fixed, which is not suitable for the transportation of terminal strips of different thicknesses and is not conducive to efficient cutting of terminals.

[0003] After searching, it was found that a terminal cutting device for a connector described in the authorization announcement number CN217343077U has the following beneficial effects: in the utility model, by rotating the threaded rod threadedly connected on the adjusting frame, one end of the threaded rod is driven to move the moving block downward under the action of the bearing seat. Since a motor is fixedly installed on the moving block and a transmission disk is fixedly connected to the output end of the motor, the transmission disk is forced to extend into the conveying track during the downward movement of the moving block until the transmission disk contacts the terminal strip set in the conveying track, thereby realizing the conveying of terminal strips of different thicknesses, and the limit block built into the conveying track can limit the terminal strip. To ensure the stability of the terminal material strip conveying, during this process, the cylinder fastened on the support frame is turned on by the control switch, so that the piston rod of the cylinder drives the cutting knife to move up and down reciprocatingly, thereby realizing the cutting of the terminal material strip; in the utility model, the terminal material strip roll is sleeved on the support shaft of the support plate, so that one side of the terminal material strip roll is fit with the limit plate welded on the support shaft, and then the positioning ring is sleeved on the support shaft, so that the multiple extension strips arranged around the outer ring of the positioning ring are fit with the other side of the terminal material strip roll, and the rubber block arranged around the inner ring of the positioning ring is cooperated, so that the terminal material strip roll is quickly fixed, and the terminal material strip roll is convenient to replace, which is convenient to use.

[0004] When it is in use, after the terminal material strip roll is used up, the equipment needs to be shut down for a long time, and a new terminal material strip roll needs to be manually replaced. Subsequently, the conveying and cutting work needs to be carried out, which will reduce the overall equipment working efficiency and the use effect is not good. Therefore, a terminal cutting device for connectors is needed for people to use. Utility Model Content
