Joining device for conduits and associated joining process

摘要

First and second conduits are joined in a manner to control electrical resistance of a conduit circuit. A cylindrical section of an adapter is placed onto an end of the first conduit. A part of the cylindrical section is crimped onto the first conduit while a spacing block made of a polymer material having a previously chosen conductivity is positioned around the end of the first conduit and clipped onto the cylindrical section. The crimping locks the spacing block to the adapter and deforms an assembly comprising the clipping pieces of the spacing block and the adapter, so as to immobilize the clipping pieces relative to each other in a direction parallel to an axis of the cylindrical section of the adapter, and such that an exterior surface of the first conduit engages interior surfaces of the spacing block and the adapter.

1. A coupling device for conduits for controlling electrical resistance of a conduit circuit, comprising:
an adapter having a cylindrical section configured to be placed and crimped onto an end of a first conduit; a spacing block made of polymeric material and configured to be clipped to said cylindrical section and to be joined to an end of another conduit, wherein a part of the cylindrical section is configured to be crimped onto the first conduit while the spacing block is clipped to the adapter and positioned around the end of first conduit, so as to lock the spacing block to the adapter and to deform an assembly comprising a clipping piece of the spacing block and a complementary clipping piece of the adapter, thereby immobilizing the clipping piece and complementary clipping piece relative to each other in a direction parallel to an axis of the cylindrical section of the adapter, and such that an exterior surface of the first conduit engages interior surfaces of the spacing block and the adapter.
