Abstract:
A contactor and lead screw driven gear are positioned on a spindle within a housing. Ears on the gear extend along the spindle and interfit with notches in the contact. A seat in the housing fits in a groove formed in the tail end of the lead screw, the screw head compresses a sealing member against a continuous bearing surface on the housing, a spacer limits lead screw movement away from the seat. A bulkhead compartmentalizes the control and inhibits movement of debris and foreign particles into the electrical section of the control. Pullout strength of lead wire terminals anchored in a ceramic base is increased by sandwiching a segment of the terminals between the base and a housing wall.
Abstract:
An electrical assembly comprises a plurality of discrete resistors connected together in stacked relationship. Each of the discrete resistors comprises a dielectric substrate having an aperture extending therethrough and a film of resistance material secured thereon. A spacer supported in each of the apertures has means preventing rotation of the spacer relative to the dielectric substrate and interfits with an adjacent spacer to prevent relative rotation of the two spacers. Terminals extend through the dielectric substrate and are electrically connected to the film of resistance material such that forces applied to the end of a terminal are not transferred to the point of electrical connection between the terminal and the film of resistance material. Each of the spacers is provided with a hole extending therethrough such that a bolt passing through the holes maintains the discrete resistors in stacked relationship.
