Abstract
The invention refers to a low-cost fuse switch module that comprises a pair of fixed contacts and a rotary contact rotatable about a rotation axis located in-between the fixed contacts. The rotary contact is rotatable between a closed position in which it is connected with the fixed contacts to enable current circulation, and an open position in which the rotary contact is electrically isolated from the pair of fixed contacts. An overcurrent protection fuse is provided for limiting maximum current circulation through the contacts in the closed position, and the fuse is rotatable about the axis and it is arranged to operate as the rotary contact of the switch, such as by rotating the fuse about the rotation axis, the switch reciprocally transit from the closed to the open position.
Claims10
A fuse switch module comprising:
- a pair of fixed contacts and a fuse operable as rotary contact, wherein the fuse is rotatable about a rotation axis that extends through a point located between the fixed contacts, wherein the fuse is rotatable between a closed position, in which the rotary contact fuse is electrically connected to both of the fixed contacts to enable current circulation between the fixed contacts, and an open position, in which the rotary contact fuse is electrically isolated from the pair of fixed contacts to prevent current circulation between the fixed contacts;
- wherein the fuse has two connection terminals at opposite ends thereof, and wherein the rotation axis extends transversally across the fuse through a point located between the two connection terminals;
- wherein the fuse switch module further comprises two conductive blades detachably fitted respectively to the two connection terminals of the fuse and wherein the two conductive blades are configured to contact the fixed contacts when the fuse is in the closed position, and wherein each blade of the two conductive blades includes a generally Y-shaped portion such that each blade of the two conductive blades has a double-walled part that engages respectively with one of the fixed contacts by elastic deformation of the double-walled part, and wherein each blade of the two conductive blades has a single-walled part that can be inserted into one of the fixed contacts;
- the fuse switch module further comprising a fuse cartridge made of an electrically insulating material, wherein the fuse is attached to the fuse cartridge such that the fuse and the fuse cartridge can rotate together, and wherein at least one of the two conductive blades protrudes outside the fuse cartridge.
