Fuse holder, especially fuse holder for electrical devices

摘要

The fuse holder contains a socket and a head member which is loosely seated in the socket by means of a quick release closure, such as a bayonet connection and can be removed along the lengthwise axis of the fuse holder. Seated in the socket at its closed end is a base contact containing a connection tab or flag and a lateral or side contact having a connection tab or flag. At the head member, the closed end of which is located at the open end of the socket, there is provided a substantially U-shaped connection conductor which fixedly claws into the head member by means of retaining or holding flaps provided at a web portion of the U-shaped connection conductor. The legs of the U-shaped connection conductor extend from the web portion of the U-shaped connection conductor at an inclination inwardly at a predetermined location towards the lengthwise axis of the fuse holder to an internal contact location for a first cap member of the fuse insert or fuse. A second cap member of the fuse insert is pressed by an axial compression or pressure spring against the base contact. The legs of the U-shaped connection conductor then again extend outwardly at an inclination up to an external contact location where they produce a frictional connection with the lateral or side contact. With a most simple construction of the fuse holder there is obtained a mechanically and electrically faultless solution, which not only possesses an extremely good tolerance range, but additionally allows converting the fuse holder so that it can handle fuse inserts of other dimensions by simply exchanging the connection conductor and the compression or pressure spring.
