CURRENT-CARRYING LEAD AND PLUG CONNECTOR HAVING SUCH A CURRENT-CARRYING LEAD

摘要

The present invention relates to an energizing lead for a plug connector, in particular a connecting lead and a heating tape (5), having at least two cords (49, 50) partially surrounded by an electrically insulating portion (47). At least one storage part 53 for storing the electrically insulating medium 54 is provided on the energizing lead wire. The reservoir 53 is closed by at least one plunger 55 capable of squeezing the electrically insulating medium 54 into at least one sealing space 58-60 through at least one discharge nozzle 57 . The plug connector having the electrification lead wires 3, 5 has a sealing structure 36 having a sealing member 66. [ The sealing member has an elastically deformable sealing portion 71 that can be elastically deformed by a wedge-shaped slider 77. [ The wedge-shaped slider 77 has a conical surface 82 that interacts with the conical surface 76 of the sealing portion 71. The wedge-shaped slider 77, which receives the compressive stress in the axial direction by the compression spring member 84, is guided into the fixing portion 78 which fixes the sealing member 66 in the axial direction. The lead wires 3, 5 are supported by the multi-point support in the deformation preventing structure 44. Each of the deformation preventing structures has a pair of compression members 91 to 94 opposed to each other and a pair of compression members 91 and 92 are positioned at right angles to the pair of other compression members 93 and 94 . The compression members of the pair of compression members 93 and 94 are forcibly guided by the compression members of the other pair of compression members 91 and 92.
