What is the connection structure of the outer casing of the epoxy-encapsulated DC contactor
Update:08-03-2023
An epoxy-encapsulated DC contactor housing connection structure, comprising a DC contactor housing with an open upper end, the DC contactor housing is equipped with various components of the DC contactor, and after the upper port is fixed by an inner support cover, the DC contactor housing and the inner The outer periphery of the support cover is sealed by epoxy encapsulation, the upper port of the outer shell of the DC contactor extends outward beyond the outer surface of the inner support cover, and the upper port of the outer shell of the DC contactor is provided with a number of riveting points at intervals. points are respectively extruded and deformed to fit on the outer surface of the inner support cover. The connection structure of the outer casing of the epoxy-encapsulated DC contactor is provided with a number of riveting points on the outer casing of the DC contactor, through the extrusion deformation of the material and the inner support. The cover is bonded together, which greatly improves the connection strength between the inner support cover and the outer shell of the DC contactor. After the DC contactor is disconnected, the internal air pressure rises and it is not easy to break through the effect of the encapsulated epoxy, which improves the electrical life of the product and the safety of use.
