Abstract: A conductive polymer composition which has low resistivity and good electrical stability. In one aspect the composition comprises a nonconductive filler which is a dehydrated metal oxide. In an another aspect the composition comprises a conductive filler which is metal particles in which the bulk density is less than 0.15 times the true density. Compositions of the invention are particularly useful for circuit protection devices (1).

Abstract: An electrical device (1) in which a first connection element (7) is in electrical contact with a resistive element (3). The first connection element (7) defines a cavity (11) into which, when the cavity is empty, a second connection element (21) can be inserted. The second connection element (21), which may be connected to a source of electrical power, is partially within the cavity (11), makes physical and electrical contact with the first connection element (7), and protrudes from the cavity. Such devices (1) can be made in a continuous process by a method of the invention. They are particularly suitable for insertion into a circuit board (31).

Abstract: L'invention se rapporte à un dispositif électrique (1) dans lequel un premier élément connecteur (7) se trouve en contact électrique avec un élément résistif (3). Ce premier élément connecteur (7) définit une cavité (11) qui, lorsqu'elle est vide, peut recevoir un second élément connecteur (21). Ce second élément connecteur (21), qui peut être connecté à une source de courant électrique, est partiellement contenu dans la cavité (11), établit un contact physique et électrique avec le premier élément connecteur (7) et fait saillie à partir de la cavité. De tels dispositifs (1) peuvent être fabriqués en continu selon un procédé décrit dans la présente invention. Ils sont particulièrement appropriés pour être insérés dans une carte à circuits (31).
