Patent FR-2553688-A1 (FR)
Title: Method for attaching a capillary tube and device for the implementation of the method
Inventor: URBAN OLE
IPC: H01H37/36
Filed: 1984-10-19
Abstract: In a method for attaching a capillary tube 4 in an elongate hole 3 of a part 1, the initial step is to produce, on the capillary tube 4, a bulged portion 5 whose external diameter d is greater than that of the hole. The bulged portion 5 and the entrance of the hole are pressed against each other in the axial direction and connected to each other by passing an electric current. A leaktight and strong attachment is thus obtained without needing a flux.
