The five major factors that should be paid attention to when connecting the cable connector - the semiconductor shielding treatment in the wire and cable must be read. If the cable body has an inner shielding layer, the inner shielding layer of the connector of the crimping tube conductor must be restored when making the joint, and the inner semiconductor shielding of the cable must be A portion is left so that the shields in the connector on the connecting tube can communicate with each other to ensure the continuity of the inner semiconductor, thereby uniformly distributing the field strength at the joint stub.
The connecting conductor connection of the conductor requires low electrical resistance and sufficient mechanical strength, and no sharp corners can occur at the joint. Medium and low voltage cable conductor connections are commonly used for crimping. Crimp should be noted:
(1) selecting a conductor connecting tube of suitable electrical conductivity and mechanical strength;
(2) The inner diameter of the crimping tube and the outer diameter of the connected core are 0.8-1.4 mm.
(3) The resistance of the joint after crimping should not be greater than that of the conductor of equal section! ) times, the tensile strength of the copper conductor joint is not lower than;
(4) Before the crimping, the outer surface of the conductor and the inner surface of the connecting tube are coated with a conductive adhesive, and the oxide film is broken by a wire brush;
(5) The connecting tube, the sharp corners on the core conductor, the burrs, etc., are smoothed with a trowel or sandpaper. Http://news.chinawj.com.cn
