Embodiment 1
[0024] see figure 1 As shown, the cable crimping sleeve for a three-layer co-extrusion cable includes a crimping round tube 100 made of steel. A partition 200 is arranged in the middle of the crimping round tube 100. The area surrounded by the inner tube wall of 100 forms the first crimping cavity 110 and the second crimping cavity 120 respectively, the length L1 of the crimping round tube 100 is 90mm, the thickness of the partition part 200 is 10mm, the first crimping cavity 110 and the second crimping cavity The lengths l1 and l2 of the two crimping chambers 120 are both 40 mm, the inner diameters of the first crimping chamber 110 and the second crimping chamber 120 are the same, and the tube wall of the crimping round tube 100 is 1.2 mm.
[0025] The three-layer co-extrusion cable crimping process utilizing the crimping sleeve of embodiment 1 comprises the following steps:
[0026] The two specifications that need to be crimped are at 120mm 2 The number of monofilaments i...
Embodiment 2
[0028] see figure 2 As shown, the cable crimping sleeve for a three-layer co-extrusion cable includes a crimping round tube 100a made of steel. The area enclosed by the inner tube wall of 100a respectively forms a first crimping cavity 110a and a second crimping cavity 120a. The length L2 of the crimping tube 100a is 130mm, the thickness of the partition part 200a is 10mm, the lengths l1a and l2a of the first crimping chamber 110a and the second crimping chamber 120a are both 60mm, the first crimping chamber 110a and the second crimping chamber 120a The inner diameter of the tube is the same, and the tube wall of the crimping round tube 100a is 2.5 mm.
[0029] The three-layer co-extrusion cable crimping process utilizing the crimping sleeve of embodiment 2 comprises the following steps:
[0030] The specification that needs to be crimped is 150mm 2 and above cables are stripped of the outer layer monofilament to obtain the second outer layer core, and then the outer layer...
Embodiment 3
[0032] see image 3 As shown, the cable crimping sleeve for a three-layer co-extruded cable includes a crimping round tube 100b made of steel. The area enclosed by the inner tube wall of 100b respectively forms a first crimping cavity 110b and a second crimping cavity 120b. The length L3 of the crimping tube 100b is 130mm, the thickness of the partition part 200b is 10mm, the lengths l1b and l2b of the first crimping cavity 110b and the second crimping cavity 120b are both 60mm, and the inner diameter of the first crimping cavity 110b is smaller than that of the second crimping cavity. The inner diameter of the connecting chamber 120b and the outer diameter of the outer surface of the first crimping chamber 110b are smaller than the outer diameter of the second crimping chamber 120b, forming a circular tube with a flaring section, and the wall of the crimping circular tube 100b is 2.5mm.
