摘要:
Le déclencheur comprend un noyau fixe (20) adapté pour être monté sur une culasse (5), un noyau mobile (24) pouvant se déplacer entre une position éloignée du noyau fixe et une position rapprochée du noyau fixe, et une tige de déclenchement (22) reliée au noyau mobile et s'étendant au travers d'un alésage (21) du noyau fixe. Son procédé de fabrication consiste à réaliser la tige de déclenchement (22) par surmoulage simultané à l'intérieur du noyau fixe (20) et à l'intérieur du noyau mobile (24) et à effectuer une opération de décollage entre le noyau fixe et la tige de déclenchement afin de la désolidariser définitivement du noyau fixe.

Disjoncteur de phase et neutre, comportant un boîtier modulaire de largeur normalisée dont la base (1) est prévue pour être fixée dans un rail de dimension standard, et conçu de manière telle que, dans le but de donner aux chambres de coupure le plus grand volume possible, compte tenu des dimensions normalisées du boîtier modulaire, et simultanément d'alléger et de réduire le dimensionnement du mécanisme à serrure, on prévoit que les moyens magnétiques (33, 34) sont situés à proximité immédiate de l'organe de manoeuvre (5) et au contact de l'entretoise, de sorte d'une part que la distance séparant les deux plans parallèles contenant respectivement l'axe longitudinal des moyens magnétiques (90) et celui du pivot de l'équipage mobile soit la plus courte compatible avec le couple minimum de déclenchement dudit mécanisme et, d'autre part, que toute la partie centrale du volume délimité par l'entretoise et la coque lui faisant face, pratiquement jusqu'à hauteur desdits moyens magnétiques est occupée à chaque étage par la chambre de coupure respective.

This invention relates to a method of manufacturing a circuit breaker. Known methods suffer from the drawbacks of difficult preassembly of the breaker mechanism because it is held together by the housing and also because it is difficult to automate the process because parts need to be assembled along three orthogonally related axes. The above problems are solved by peassembling the movable parts of the circuit breaker (10) between a pair of frame members (42, 89) supporting the unitary breaker assembly (40) without attachments. Other circuit breaker components, attached to the unitary breaker assembly, are also supported in the housing (11) without attachments. A cover (11b) is secured to the housing to complete the circuit breaker. Another version of the invention preassembles the movable parts of the circuit breaker (10') and the stationary contact mechanism (28) and trip coil (31) with the line and load terminals (12, 14) attached, between a pair of supporting frame members (105) to form an operable circuit breaker module (40). The module (40) is in turn supported in a housing (11) without attachments. The circuit breaker module (40) may be tested and adjusted prior to final assembly.
摘要:
A resettable, current-responsive, circuit interrupter device has two wide but thin terminals embedded up to a substantial part of their thickness in a side wall of an insulating housing so that sides of the embedded terminal portions are exposed from the housing material along the side wall inside the housing. Terminal ends extend from the bottom of the housing to be connected in a circuit and extend through the top of the housing to be accessible for test purposes. An electrical contact is mounted on the exposed side surface of one embedded terminal portion and a thermostatic strip element is secured to the exposed side surface of the other embedded terminal portion to extend closely along the one housing side to normally engage the contact in a very compact, closed circuit position of the device. A lid overlies the thermostatic strip element. The thermostatic strip element has a selected resistivity and the wide terminals have substantial current capacity so the thermostatic strip self-heats to a selected temperature to open the circuit in response to occurrence of a precisely predetermined overload current condition in the device circuit at any ambient temperature likely to be encountered in an automotive environment.
