Abstract

The security system has a cylindrical casing or box with two flat ends. There is a connector in the center or one of the flat ends. There is a stack of electronic circuit cards adjacent to the connector and there is a connection to a battery or other autonomous source of energy. There is a movable cover or hatch in the side of the cylindrical casing. The end of the casing opposite to the connector contains a pyrotechnic initiator.

Description

<Desc/Clms Page number 1> <Desc / Clms Page number 1>

La présente invention concerne un dispositif de sécurité de mise de feu électronique sans désalignement de chaîne pyrotechnique.  The present invention relates to an electronic firing safety device without misalignment of the pyrotechnic chain.

La sécurité de mise de feu traditionnelle se fait généralement par désalignement et mécaniquement.  The traditional firing safety is generally done by misalignment and mechanically.

Les dispositifs de sécurité de mise de feu existants reposaient sur un désalignement mécanique de le chaîne de mise de feu des systèmes.  The existing firing safety devices were based on a mechanical misalignment of the firing chain of the systems.

Le dispositif selon l'invention permet de remédier à l'obligation de désaligner les composantes pyrotechniques de la chaîne de mise de feu tout en garantissant les exigences de sécurité Le dispositif comporte un circuit de commande, un dispositif d'alimentation autonome, un circuit de mise de feu.  The device according to the invention makes it possible to remedy the obligation to misalign the pyrotechnic components of the firing chain while guaranteeing safety requirements. The device comprises a control circuit, an autonomous supply device, a firing.

Ce dispositif est présenté sous forme d'un boîtier hermétique avec à ses extrémités un connecteur étanche pour les liaisons électriques, et un initiateur pyrotechnique de type 1A 1W pour l'initiation pyrotechnique.  This device is presented in the form of a hermetic box with at its ends a waterproof connector for the electrical connections, and a pyrotechnic initiator of type 1A 1W for the pyrotechnic initiation.

La réalisation de ce boîtier assure l'étanchéité complète aux environnements électromagnétiques et climatiques. Il permettra la mise en place de la source d'énergie au moment opportun pour assurer la sécurité lors des manipulations.  The construction of this box ensures complete sealing against electromagnetic and climatic environments. It will allow the energy source to be put in place at the right time to ensure safety during handling.

Les dessins annexés illustrent l'invention La figure 1 représente une vue en coupe du dispositif La figure 2 représente une vue de dessus du dispositif de sécurité
En référence à ces dessins, le dispositif de sécurité de mise de feu comporte un boîtier (1) avec la présence d'une trappe (2) munie d'un joint pour mise en place de la source autonome (3). The accompanying drawings illustrate the invention Figure 1 shows a sectional view of the device Figure 2 shows a top view of the safety device
With reference to these drawings, the firing safety device comprises a housing (1) with the presence of a hatch (2) provided with a seal for positioning the autonomous source (3).

Le connecteur (4) est prévu pour recevoir les informations de commande de l'opérateur via un signal électrique. Les informations de commande, de traitement de la sécurité, de retard et de commande, de mise de feu sont traitées dans des cartes distinctes (5) dédiées à chaque fonction.  The connector (4) is designed to receive operator control information via an electrical signal. The ordering, safety processing, delay and ordering information, firing information are processed in separate cards (5) dedicated to each function.

L'initiateur pyrotechnique (6) est ajusté dans l'axe du bord du boîtier pour réduire les risques de destruction suite à une manipulation.  The pyrotechnic initiator (6) is adjusted in line with the edge of the housing to reduce the risk of destruction following handling.

L'initiateur pyrotechnique (6) sera déclenché après combinaisons des différentes chaînes fonctionnelles résultat du traitement des différentes cartes électroniques The pyrotechnic initiator (6) will be triggered after combinations of the different functional chains result of the processing of the different electronic cards
