Cable connector manufacturing method

1. Cable cutting

2. Stripping cable

Strip the cable as shown in the figure (A/2+B) and cut the end into a reaction cone (commonly known as the "pencil head"), then puncture the receiving crimp. After crimping, flatten the protruding part and wipe the receiving and insulating surface with a petrol cloth.

The crater is first filled with epoxy putty, and the receiving and exposing core is wrapped with a semiconductor tape or a semiconductor rubber tape, and then wrapped with a self-adhesive rubber tape until the shape and scale are shown. In the figure, J is the insulation diameter of each core. The semiconductor tape on both sides is wrapped tightly and completely in the entire insulation appearance.

The aluminum foil was semi-finished with a thickness of about 0.1 mm to be tightly wound on the semiconductor tape and placed with a 20 mm stack of copper shields at both ends of the cable. Then tie the two ends with tinned copper wire, and use a soft copper wire to wrap around the entire shield, and solder the copper wire at the place where the two ends are in contact with the copper wire. It is outsourced with two layers of plastic adhesive tape and then wrapped with a layer of white cloth.

The insulated cores are gathered together, filled with jute, etc., to restore the original shape, and wrapped with a wide cloth tape.

If the glue is not filled, after the original shape is recovered, the two layers of plastic adhesive tape are wrapped in a semi-overlay as a waterproof sealing layer, and then the plastic box placed at one end is displaced positively, and the screw cap is tightened. If the glue is filled, after the plastic box is installed, the No. 1 asphalt glue or low-temperature insulating resin is poured into the mouth at one end, and the pouring port at the other end can be emerged.

Regarding the 3kV and below and 6kV turnkey shielded plastic cables, the manufacturing process of the core joint is basically the same as the above process, and the difference lies in the treatment of the shield layer. The 6kV turn-on shielded cable should be covered with 0.1mm aluminum foil as a shielding layer after the three cores are closed together, and stacked with the original cable cover shielding layer of 20mm, and tied with copper wire. Cables of 3kV and below are not used for shielding.

(1) Saw steel shovel, lead-cutting, and flared bell mouth. Take the required scale according to Figure 3-109 (a), tie the wire on the outer sheath of the two sides of the cable, and peel off the outer sheath. The wire is tied to the steel sill of the outer sheath with a fracture of 50 mm, and the other steel shovel is stripped. The inner cushion layer was torn off, and the outer surface of the lead package of 200 mm from the steel smash was cut, and the 120 mm lead package was stored, and the other strips were removed. Expand the bell mouth and tear off the semiconductor paper outside the bell mouth. Save the package with 20mm insulation and other stripping.

(3) Fix gloves and insulating tubes. Glove the glove into the base of the three-pronged mouth because the root of the finger is heated and fixed to both ends. Then insert the insulating tube into the root of the three forks and heat it from the root.

Take the 1/2 pick-up length plus 5 mm from the end of each phase of the core wire, and strip the trapped tubing and core insulation paper. Then take 35mm from the insulation fracture, peel it into a 30mm long cone, and leave a 5mm semi-conductive layer. The crimping received by the carrier is carried out in a fundamental operating process.

(6) Wrapped PTFE belt, fixed grease trap, outer insulating tube and semi-catheter. Wrap the PTFE belt 300mm as shown in Figure 3-109 (b), and place the grease trap on the PTFE belt, and heat it from the center to both ends. Then, the outer insulating tube is sleeved on the grease trap, and is heated and fixed from the center to both ends. The two semi-conductors are sleeved on the insulation, and the ends of the two overlapping gloves are 10 mm, which are sequentially heated and fixed from the two ends to the center.

The ends of the two sheaths are assembled with the sheath tube, and the two ends are tied to the steel sill. Then, the sealing sleeve is sleeved on the end of the sheath, and one end of the protective sleeve portion is 100 mm, and the other end is overlapped with the outer sheath of the cable 200 mm, and is heated and fixed.

(1) Strip the cable. Remove the outer sheath according to the scale required in Figure 3-110 (a), tie the wire on the steel shovel 50mm from the fracture, and strip the other steel shovel. Store 20mm inner sheath, remove and remove the filler.

(3) Fix the stress tube and insert the tube. The stress tube is placed on each of the core wires on both sides, and the copper shielding layer is overlapped by 20 mm and fixed by heating. Insert the sheath end, the sealing sleeve and the sleeve part at the longer end of the stripping cable. Insert the insulating tube (2 pieces), the half tube (2 pieces) and the copper net on each core line. The short end is inserted into the sheath end and the sealing sleeve.

(4) Crimp receiving. At the end of the core wire, take 1/2 of the receiving length plus 5 mm and cut off the insulator. The insulator fracture was taken up to 35 mm, cut into a 30 mm long cone, and a 5 mm semiconductive layer was left. The crimping of the receiving is carried out in accordance with the fundamental operating process.

(6) Fixed semi-catheter, device shielding net and ground wire. The two semi-conductors are sleeved on the insulating tube, and the copper shields on both ends are overlapped by 50 mm, and are sequentially heated and fixed by the two ends toward the center.

(7) Fix the sheath. The sheath ends of the two ends are assembled with the sleeve portion, and the two ends are tied to the steel sill. The sealing sleeve is sleeved on the end of the sheath, and the overlapping portions of the two ends and the outer sheath of the cable are 100 mm, and are fixed by heating.
