Abstract
The utility model discloses a device used for bypass short circuit of a logging cable. The device comprises a bypass body (1). The bypass body is a circular column. Two ends of the bypass body are respectively provided with inner taper threads (2) and outer taper threads (3). The bypass body is provided with an eccentric through hole (4). The circular column far from the eccentric through hole is provided with an installing surface (5). The installing surface is provided with a cable locking assembly (6). The lower part of the cable locking assembly (6) is provided with a cable leading-in hole (7). The opening of the cable leading-in hole is provided with a sealing assembly (8). A contact surface of the device and the cable is provided with a copper base plate. Hardness of the copper base plate is relatively low, and the copper base plate would not damage the cable, and locking force of the cable can be adjusted. A rubber casing with V-shaped grooves on two ends is used in the sealing device of the device. Under extrusion of V-shaped rings and V-shaped bosses, two ends of the rubber casing expand outwards, and sealing pressure reaches 14-15 Mpa at the most. The rubber casing is provided with a plurality of circular groove, multiple sealing is formed, so leakproofness is good, and pressure resistance is high.
