The fuse holder contains a socket and a head member loosely seated in the socket by a quick release closure, 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 and a lateral contact having a connection tab. 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, asymmetric connection conductor fixedly clawing into the head member by retaining flaps provided at a web portion of the connection conductor. The unequal legs of the connection conductor extend from the web portion 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. A second cap member thereof is pressed by an axial compression spring against the base contact. One leg of the connection conductor again extends outwardly at an inclination up to an external contact location where it produces a frictional connection with the lateral contact. The other leg of the connection conductor extends outwardly at an inclination up to a supporting location at the inside of the head member and bears with its support arm against the inside of the head member.

Fuse holder, especially fuse holder for electrical devices

The fuse holder comprises a socket member composed of two thermoplastic members joined by ultrasonic welding with formation of a solder-tight welding joint or seam. Contact members disposed within the socket member extend to the exterior and include sealing members or locations which are sealingly enclosed in the welding joint. A lateral contact of these contact members is connected electrically to the connection conductor of a head member made of synthetic material by a bayonet joint and a spring is provided to supply the engagement pressure effective at the fuse.

Fuse holder, especially fuse holder for miniaturized fuses

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.

A bayonet connection between two electrically conductive components, especially for fuse holders, wherein at least one connection component possesses an electrically conductive spring which is electrically conductively connected with the one connection component. This spring, when there is established a connection between the connection components, electrically conductively contacts the second connection component.
