    Foventicm patent
    Technical area
    This invention relates to a cable fixing joint, in particular a fixing joint "t. electrical equipment. It belongs more generally to the technical field on your cable fixing utensils.
    State of the art
    The cable fixing joint (also called waterproof cable joint or cable joint) is widely used for fixing and protecting wires and cables on electrical mechanical equipment, ship electrical equipment and anti -ormsife equipment.
    This fixing joint is used mainly to ensure water resistance, impermeability as well as. dust-proofness of the cable outlet and, moreover, to ensure the proper functioning and the reliability of the staff. However, the performance of the fixatimi of conventional fixing joints remains weak, the joints are likely to be shaken due to b 20 teetion and.Can cause the jerking of the cable joint, and disturbing its "uti & atioa. In addition, performance such as waterproofing, dustproofing and. resistance to acid and Γ alkali are also low. which requires frequent repairs and, if necessary, replacements after long use.
    This is the problem which is solved by the present invention.
