BIPOLAR ELECTRICAL CONNECTOR PARTICULARLY FOR CONNECTING FLAME DETECTOR THERMOCOUPLES TO A MAGNETIC ASSEMBLY CONTROLLING GAS FLOW IN A BURNER

摘要

Bipolar electrical connector particularly for connecting flame detector thermocouples to a magnetic assembly controlling gas flow in a burner comprising a first central electrical contact member intended to engage a complementary first electrical contact terminal of the magnetic assembly and a second electrical contact terminal surrounding said first electrical contact terminal of the magnetic assembly in turn surrounding the first terminal, said first and second electrical contact member being mounted in a plug structure constituting an insulating member retaining said contact members and said first and second terminal being mounted on an electrical contact end of the magnetic assembly, while both first and second electrical contact member and both first and second terminal are positioned such that said first member and the corresponding terminal and the second member and the corresponding terminal are provided in such positions that engage one with the other contemporaneously and with a single mutual engagement movement, characterized in that at least one of the contact terminals and the corresponding contact member have mutual, movable coupling means, comprising cooperating elastic mutual interlocking surfaces that are partially oriented transversal to the direction of engagement/disengagement of connection member or members on contact terminal or terminals.
