Summary: | Continuous increase in demand for electricity causes that electrotechnical industry is relentlessly under pressure of technological development. It is necessary to reduce costs while
increasing a reliability of manufactured products. Common miniaturization of products
mounted in land vehicles, vessels and airplanes along with limitation of their weight requires
the use of innovative production methods. This publication presents the problem of exploitation related with reliable assembly and disassembly of rail-mounted electrical connectors.
In order to improve the reliability of injected electrical connector housings, the authors
proposed the selective induction heating technology as a heating method of injection mould.
To reveal the origin of the problem, in case of this work, the simulation studies of filling the
mould cavity were carried out. They show an incorrect localization of polymer streams weld
line. Then the results of the simulation and induction heating experiment are presented. They
were necessary for the proper design and make of the injection mould. In the final stage, the
experimental tests of the manufactured housings assembly and disassembly were performed
in conditions corresponding to the actual conditions. The obtained results show, that selective induction heating technology has significantly improved the reliability of rail-mounted
electrical connector housings. |
