Title (EN) CLIP-ON PROTECTOR
(FR) DISPOSITIF DE PROTECTION A PINCES
Abstract: front page image
(EN)Protective devices for use with conventional over-voltage protectors, especially applicable for use in protection of communication equipment. The device of this invention overcomes the prior art problems of lack of reliability, excessive size and cost, installation and maintenance difficulties, and various other problems more fully understood in the specification. The apparatus in the preferred embodiment features a small, cylindrical housing (10, 11, 12), connectors (13, 14) designed to attach simply to the electrodes of a standard over-voltage protector (23, 23A, 23B), and dual grounding paths for increased reliability and activated upon heat transfer upon sustained overload from the over-voltage protector. These paths are described as from ground-connected plates (16) to normally tensioned springs (17) to plungers (18) to electrical transfer plates (13), effected when fusible elements (19) are fused by heat conducted from the over-voltage protector (23) through heat transfer plate (14).
(FR)Dispositifs de protection utilisables avec des protecteurs de tension de type conventionnel, en particulier dans le domaine du materiel de communication. Le dispositif selon l"invention resoud les problemes que posent les dispositifs connus en matiere de manque de fiabilite, de dimensions excessives et de cout, de difficultes d"installation et d"entretien, ainsi que d"autres problemes dont on comprend mieux la nature en lisant la description. L"appareillage, selon un mode d"execution prefere, comprend un boitier cylindrique de petites dimensions (10, 11, 12), des connecteurs (13, 14) concus pour s"adapter aux electrodes d"un protecteur de tension de type courant (23, 23A, 23B), et deux circuits de mise a la terre ameliorant la fiabilite et actives par transfert de chaleur resultant d"une surcharge du protecteur de tension. Ces circuits de mise a la terre comprennent des plaques (16) reliees a la terre, des ressorts (17) sous charge normale, des pistons (18) et des plaques de transfert electrique (13), et entrent en action lorsque des fusibles (19) fondent sous l"action de la chaleur transportee depuis le protecteur de tension (23) par la plaque de transfert de chaleur (14).
