DESIGN METHOD FOR SEALED FUSE HOLDER WITH ISO MICRO RELAY

A novel electrical box to house one or more ISO micro relays, is adapted to support IP67 and IP69K Ingress Protection ratings. The housing of the electrical box is molded with blade sockets that correspond to blade positions of the ISO micro relay. The housing is also molded with terminal seats and cylindrical openings which vary, depending on the blade socket, enabling terminals of different sizes, orientations, and positions relative to the respective blades, to be easily inserted into the back of the housing. The resulting position of the terminals ensures that electrical connections to the ISO micro relay are made and ingress protection of components inside the electrical box is ensured.
