The specific implementation mode is as follows: when in use, firstly, as shown in fig. 5 and 6, the shielding tube 2 is pushed into the feeding rod 72 by a preset length through the material pushing ring 73; the shielding tube 2 is then cut by the cutter 22 of the second cutter assembly 60. As shown in fig. 7, the feed bar 72 feeds the cut shield tube 2 between the heating plates 31. As shown in fig. 8, the negative pressure ring 11 sucks the end of the insulating tube 1, and pulls the insulating tube 1 around the shield tube 2. The insulating tube 1 is cut off by the cutter 22 of the first cutter assembly 20, and the negative pressure ring 11 drives the insulating tube 1 to continuously move for a preset distance, so that the shielding tube 2 is located at the middle section position of the insulating tube 1. As shown in fig. 9, the two heating plates 31 simultaneously move the middle to wrap the insulating tube 1, and then the two ends of the heating plates 31 are heated first, so that the two ends of the insulating tube 1 are heated first to shrink, the two ends of the insulating tube 1 are attached to the feeding rod 72, and the outer diameter of the feeding rod 72 is the inner diameter of the two ends of the cable connector. Then the middle section of the heating plate 31 starts to heat, so that the middle section of the insulating tube 1 is heated to shrink, and the middle section of the insulating tube 1 is attached to the shielding tube 2 after shrinking, so that the shielding tube 2 is fixed in the insulating tube 1. The insulating tube 1 after heating is in the state shown in fig. 11 and 15. As shown in fig. 10 and 11, the feed bar 72 starts to retract, and the cable connector is disengaged from the feed bar 72 by the fork 40. After the feed rod 72 is retracted, as shown in fig. 5 and 6, the shield tube 2 is pushed into the feed rod 72 by a predetermined length by the push ring 73, and the negative pressure ring 11 is moved to the port of the insulating tube 1 again to fix the insulating tube 1 by suction, thereby manufacturing the next cable connector.
The foregoing is only a preferred embodiment of the present invention and is not intended to be exhaustive or to limit the invention. It will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention.
