  • Patent number: 9502877
    Abstract: The present invention provides an inlet funnel (100) for cable terminal, which comprises a funnel body part (10) and a fixation part (20). The funnel body part (10) has one end with a smaller opening and the other end with a larger opening, said funnel body (10) having a gradually increasing diameter (D) from said one end with the smaller opening to said other end with the larger opening, and the funnel body (10) is suitably to be installed over an electrical cable (C). The fixation part (20) is provided at said other end with the larger opening of said funnel body part (10) and adapted for the attachment of said inlet funnel (100). The inlet funnel (100) further comprises a pretreated mounting part (30) extending from said one end side with the smaller opening towards said the other end side with the larger opening. Accordingly, the inlet funnel for cable terminal according to the present invention may reduce workload, save time, and simplify the mounting process.

  • Patent number: 9343893
    Abstract: A device and a method for a field expansion. A support core (30) is inserted into the device by a field expansion apparatus. The field expansion apparatus has a pressure applying means (20) defining a radially expandable inner surface and a flat surface radially outwardly extending from the radially expandable inner surface. The device comprises an elastomeric tubing (10) and an adapter (40). The elastomeric tubing (10) has a forward end opposite a rearward end and an axial bore extending therethrough configured to receive the support core (30). The adapter (40) has a step portion (41) defined by a radial outer surface (42) and a flat surface (43) radially outwardly extending from the radial outer surface (42), and an axial bore (44) extending therethrough. The axial bore (44) has a diameter substantially the same as the diameter of the axial bore (12) of the elastomeric tubing (10).
