Abstract

A fuse block, particularly for printed circuits, consists of a small block of insulating material, having a "U" shape, to whose wings are locked two equal terminals, provided at the bottom with a coupling for printed circuit and at the top with two prongs designed to receive a head of a fuse, restrained by a small frame. From the small frame extend two wings shaped in such a way as to allow the easy insertion between themselves of the fuse and the subsequent elastic restraint of the fuse.

Claims

1. A holder for a cartridge type fuse having a body and a conductor at each end, comprising:

a frame member having a longitudinal axis and a transverse axis, said frame being longer along the longitudinal axis;

a pair of L-shaped wings, each wing having an arm with one end attached to one surface of the frame member and a transversely extending finger at the other end thereof, said wings spaced on opposite sides along the length of the frame member with the fingers thereof spaced from the frame oppositely transversely directed toward opposite longitudinal sides of the frame, a fuse inserted by being placed oblique to the longitudinal axis of said frame and rotated into the opposite open sides of the wings and held on said fingers.

2. A holder as in claim 1 wherein each said wing is of resilient material and the fuse is held therebetween by a friction fit.

3. A holder as in claim 2 wherein the finger of each wing has a cutout portion receiving the body of the fuse.

4. A holder as in claim 1 wherein the fingers are spaced apart by a distance such that the conductive ends of the fuse extend outwardly thereof.

5. A holder as in claim 4 further comprising a block receiving the frame with the fuse therein, said block having a conductive terminal at each end for receiving the conductor end of the fuse.

6. A holder as in claim 5 wherein there is a force fit relationship between the frame and the block.

7. A holder as in claim 5 wherein each said wing is of resilient material and the fuse is held therebetween by a friction fit.

8. A holder as in claim 7 wherein each said wing is of resilient material and the fuse is held therebetween by a friction fit.

9. A holder as in claim 5 wherein the fingers are spaced apart by a distance such that the conductor ends of the fuse extend outwardly thereof.
