Description

Empalme mejorado de línea eléctrica protegida.Enhanced power line splice protected.

Object of the invention

Empalme mejorado de línea eléctrica protegida, formado por un conductor plano que forma un doblez que se extiende por el contorno de una pieza aislante que incorpora dos tuercas alojadas en su interior.Improved connection of protected power line, formed by a flat conductor that forms a fold that extends by the contour of an insulating piece that incorporates two nuts housed inside.

Background of the invention

El empalme objeto de esta memoria descriptiva es de especial aplicación para las líneas eléctricas que se extienden por el interior de los carriles aislantes aplicables a grúas y equipos móviles en general. Posee una disposición y forma que permite su rápido ensamblaje. En este tipo de líneas los conductores son preferentemente de cobre y discurren por el interior de carriles aislantes, normalmente de PVC o similares.The joint object of this specification is of special application for power lines that extend inside the insulating rails applicable to cranes and mobile equipment in general. It has a disposition and form that It allows quick assembly. In this type of lines the conductors are preferably copper and run inside of insulating rails, usually of PVC or similar.

El solicitante del presente modelo de utilidad ya presentó en su día el modelo N° 9801753 titulado "empalme de línea eléctrica protegida" que consistía en un empalme realizado sobre una línea cuyo conductor es un segmento plano de cobre. En los extremos de dicho segmento se formaba un pliegue que albergaba en su interior la cabeza de un tornillo. Dicha cabeza era cuadrada y tenía la misma forma y anchura que el pliegue formado por el conductor, de tal manera que al apretar el tornillo la base permaneciera fija y no se desplazara deformando las paredes del conductor de menor resistencia que las paredes del tornillo, el cual, al atravesar el conductor, presentaba su extremo libre perpendicularmente a la línea. Por dicho extremo se introducía una pletina que formaba el puente entre dos conductores. La pletina era rectangular con dos orificios que la atravesaban. El último elemento que completaba el empalme era la tuerca con su correspondiente arandela moleteada. Además se tenía en cuenta los diferentes coeficientes de dilatación existentes entre el PVC de los carriles aislantes y el cobre del conductor interior. Dado que los empalmes se realizaban al descubierto para tener acceso a la colocación de las pletinas puente y al apriete de las tuercas, una vez que se han completado los empalmes, el hueco se tapaba con una cubierta externa aislante. El empalme así realizado presentaba una modularidad permitiendo la colocación de nuevos carriles y la sustitución de otros ya tendidos. Este tipo de empalme dispone de una gran robustez gracias a la pletina que hace de puente entre ambos extremos de los conductores.The applicant for this utility model already presented in its day the model N ° 9801753 entitled "splicing of protected power line "which consisted of a splice made on a line whose conductor is a flat segment of copper. In the ends of said segment formed a fold that housed inside the head of a screw. That head was square and had the same shape and width as the crease formed by the conductor, in such a way that when tightening the screw the base remain fixed and will not move by deforming the walls of the conductor of less resistance than the screw walls, the which, when crossing the conductor, presented its free end perpendicular to the line. By this end a plate that formed the bridge between two conductors. The plate was rectangular with two holes that crossed it. The last element that completed the joint was the nut with its corresponding knurled washer. It also took into account the different expansion coefficients between the PVC of the rails insulators and copper from the inner conductor. Since the splices were performed in the open to access the placement of the bridge plates and the tightening of the nuts, once they have been Completed the splices, the hole was covered with an external cover insulating. The splice thus made presented a modularity allowing the placement of new lanes and the replacement of others already lying. This type of splice has a large robustness thanks to the plate that acts as a bridge between the two conductor ends.

Posteriormente el solicitante presentó el modelo de utilidad N° 200003100 titulado "perfeccionamientos en empalme de línea eléctrica protegida", de constitución similar al anterior modelo de utilidad citado (9801753) pero variando tanto la pieza de unión como los elementos de sujeción. También la cubierta aislante externa que cubre la conexión incorpora una mejora tendente a proporcionar un mayor aislamiento, evitando el contacto entre los conductores o entre la tuercas de apriete. La unión de los segmentos planos constitutivos del conductor se realiza mediante una pieza de unión que atraviesa los tornillos emergentes y se asegura con sus correspondientes medios de sujeción, tapando dicha unión con un elemento que lo recubre y que abarca simultáneamente el exterior del carril. La citada pieza de unión está formada por un cuerpo de contorno rectangular con un doblez lateral en "L", presentando el lado mayor un orificio pasante y un extremo final acanalado mediante una abertura en "U".Subsequently the applicant presented the model of utility N ° 200003100 entitled "improvements in splicing of protected power line ", of similar constitution to previous utility model cited (9801753) but varying both the connecting piece as the fasteners. Also cover external insulation covering the connection incorporates an improvement tending to provide greater isolation, avoiding contact between the conductors or between the tightening nuts. The union of flat segments constituting the conductor is done by a connecting piece that goes through the emerging screws and ensures with its corresponding fastening means, covering said union with an element that covers it and that simultaneously covers the outside of the lane The mentioned piece of union is formed by a rectangular contour body with a lateral "L" fold, the main side presenting a through hole and an end end ribbed through a "U" opening.

Con las mejoras incorporadas en la presente memoria se mantienen todas las ventajas anteriormente citadas y se incorporan otras nuevas que mejoran el funcionamiento del empalme y la manipulación durante el montaje o la reposición.With the improvements incorporated in this memory all the aforementioned advantages are maintained and incorporate new ones that improve the functioning of the joint and handling during assembly or replacement.
