Abstract

Conjunto electromecánico de conexión entre una serie de cañones (1) utilizados en el punzado de pozos petrolíferos, donde cada cañón (3) es una carcasa cilíndrica en cuyo interior se encuentra un carrier (13) portador de cargas explosivas huecas (16) dispuestas en forma radial, donde dichas cargas huecas (16) están en contacto con un cordón de detonación que contacta también con un detonador de accionamiento eléctrico, donde la serie de cañones están unidos fijamente por piezas de unión intermedias (4 y 6) y terminando en un culote (5) en su extremo inferior, y donde dicha serie está iniciada por una cabeza de fuego (2) a la que llega desde la superficie una conexión eléctrica a través de la cual se puede ir detonando el carrier (13) de cada cañón, comenzando por el inferior de los aún activos. Cada carrier (13) presenta en su extremo inferior un zócalo aislante (15) y en su extremo superior un zócalo aislante (14) con contacto retráctil, ambos zócalos teniendo elementos de centrado del carrier y medios de fijación con dicho carrier. El zócalo aislante (15) presenta un contacto elástico contactando con el interior del tubo del cañón (3) respectivo y un orificio central por el que pueden pasar cables; asimismo, el zócalo con contacto retráctil (14) presenta en su centro un pasadizo en el que está fijado un contacto eléctrico retráctil central a resorte capaz de presionar hacia arriba. En cada carrier (13), excepto el más bajo, un primer cable “vivo” que parte del extremo inferior del contacto retráctil del zócalo superior y pasa por el orificio central del zócalo inferior del carrier (13) para ingresar en la pieza de unión intermedia (4), que contiene en su parte central inferior un switch que es una llave conmutadora que presenta dos contactos móviles que conmutan, cada uno, entre un contacto normal cerrado y uno normal abierto, siendo el normal cerrado del primer contacto móvil (superior) coincidente con el normal abierto del segundo contacto móvil (inferior), donde dicho switch es sensible a la sobre presión originada por explosión en el carrier (13) del cañón inferior de los dos cañones sucesivos, y donde dicha sobre presión es capaz de vencer un fusible mecánico cuando conmuta.
