Description

PINZA PARA LA EXTRACCIÓN DE FUSIBLES Y RELÉS CLAMP FOR THE EXTRACTION OF FUSES AND RELAYS
La presente solicitud de Modelo de Utilidad consiste, conforme indica su enunciado, en una "PINZA PARA LA EXTRACCIÓN DE FUSIBLES Y RELÉS", cuyas nuevas características de construcción, conformación, y diseño cumplen el objetivo para el cual específicamente ha sido proyectada, con una seguridad y eficacia máximas, así como con numerosas ventajas, tal como se describirá en adelante.The present Utility Model application consists, as indicated in its statement, of a "CLAMP FOR THE EXTRACTION OF FUSES AND RELAYS", whose new construction, conformation, and design characteristics fulfill the objective for which it has been specifically projected, with a maximum safety and effectiveness, as well as with numerous advantages, as will be described hereafter.
Normalmente, la operación de extracción de un fusible de la caja de fusibles donde éste se encuentra insertado resulta difícil e incómoda y en numerosas ocasiones no puede realizarse con los dedos de la mano. Cuando el fusible se encuentra dispuesto en la caja de fusibles, no existe espacio entre el cuerpo del fusible y los bordes de la caja de fusibles por donde actuar y extraer dicho fusible.Normally, the operation of removing a fuse from the fuse box where it is inserted is difficult and uncomfortable and often cannot be done with the fingers of the hand. When the fuse is arranged in the fuse box, there is no space between the fuse body and the edges of the fuse box where the fuse can be operated and removed.
Cuando debe reemplazarse un fusible en las operaciones de mantenimiento del sistema eléctrico, por ejemplo, de un vehículo, suele recurrirse a herramientas y útiles que en muchas ocasiones no son los adecuados, lo cual tiene como consecuencia que el cuerpo del fusible se rompa y éste quede inservible. Además, si el cuerpo del fusible se rompe cuando éste todavía se encuentra insertado en la caja de fusibles, la extracción del mismo se complica puesto que no existe suficiente base de sujeción para extraerlo.When a fuse must be replaced in the maintenance operations of the electrical system, for example, of a vehicle, tools and tools are often used, which in many cases are not adequate, which results in the fuse body breaking and It is useless. In addition, if the body of the fuse is broken when it is still inserted in the fuse box, its removal is complicated since there is not enough support base to remove it.
En la técnica anterior se han propuesto soluciones como la utilización de pinzas para la extracción de fusibles que típicamente comprenden un cuerpo en forma substancialmente en U que define un primer par de brazos, y un segundo par de brazos que se encuentran unidos a dicho cuerpo en la zona de unión del citado primer par de brazos. Este cuerpo está fabricado en material plástico de manera que los extremos de ambos pares de brazosIn the prior art, solutions have been proposed such as the use of tweezers for the extraction of fuses that typically comprise a substantially U-shaped body that defines a first pair of arms, and a second pair of arms that are attached to said body in the junction zone of said first pair of arms. This body is made of plastic material so that the ends of both pairs of arms
HOJA DE SUSTITUCIÓN (REGLA 26) pueden ser acercados entre sí para que trabajen como una pinza. Dichos extremos del primer par de brazos de las pinzas convencionales presentan una ranura que sirve para alojar el extremo de un fusible de tamaño pequeño. Los extremos libres del segundo par de brazos comprenden una ranura que sirve para alojar el extremo de un fusible de tamaño grande.SUBSTITUTE SHEET (RULE 26) They can be approached to work like a clamp. Said ends of the first pair of arms of the conventional clamps have a slot that serves to accommodate the end of a small-sized fuse. The free ends of the second pair of arms comprise a slot that serves to accommodate the end of a large fuse.
Este tipo de pinza permite manipular fusibles de dos tamaños de una manera eficaz y sencilla. Sin embargo, en el mercado existen actualmente tres tipos de fusibles de acuerdo con sus dimensiones: fusibles de tamaño grande, fusibles de tamaño mediano y fusibles de tamaño pequeño. Por esta razón, si en un sistema eléctrico, por ejemplo el de un vehículo, se montan fusibles de los tres tipos, el usuario debe utilizar necesariamente un mínimo de dos pinzas como las descritas si quiere manipular los citados fusibles. En el caso de que las pinzas a utilizar estén configuradas por dos pares de brazos de los cuales únicamente los extremos de un par estén provistos de las citadas muescas, el usuario (o el operario) deberá utilizar tres clases de pinzas, una para cada tamaño de fusibles.This type of clamp allows fuses of two sizes to be handled efficiently and easily. However, there are currently three types of fuses in the market according to their dimensions: large-sized fuses, medium-sized fuses and small-sized fuses. For this reason, if in an electrical system, for example a vehicle, fuses of the three types are mounted, the user must necessarily use a minimum of two clamps as described if he wants to manipulate said fuses. In the event that the tweezers to be used are configured by two pairs of arms of which only the ends of a pair are provided with said notches, the user (or the operator) must use three kinds of tweezers, one for each size of fuses.
La presente invención se ha desarrollado con el fin de solventar este inconveniente, proporcionando unas pinzas universales, capaces de acoplarse en los distintos tipos de fusibles que actualmente existen en el mercado. Las pinzas objeto de la presente invención aportan otras ventajas que resultarán evidentes en lo sucesivo.The present invention has been developed in order to solve this problem, providing universal clamps, capable of engaging in the different types of fuses that currently exist in the market. The tweezers object of the present invention provide other advantages that will be apparent from now on.
En líneas generales, la pinza para la extracción de fusibles y relés de acuerdo con la presente invención es del tipo anteriormente descrito, es decir, de las configuradas por un cuerpo que presenta una forma substancialmente en U que define un primer par de brazos. El cuerpo de las pinzas convencionales comprende también un segundo par de brazos que están unidos a dicho cuerpo en la zona de unión del citado primer par de brazos. Los extremos libres de dicho primer par de brazos presentan una ranura destinada a alojar el extremo de un fusible, mientras que los extremosIn general, the clamp for the extraction of fuses and relays according to the present invention is of the type described above, that is, those configured by a body that has a substantially U-shaped shape that defines a first pair of arms. The body of the conventional clamps also comprises a second pair of arms that are attached to said body in the area where said first pair of arms is connected. The free ends of said first pair of arms have a slot intended to accommodate the end of a fuse, while the ends

La particularidad de la pinza de la invención reside en el hecho de que por lo menos uno de dichos pares de brazos incluye cada uno una muesca en su extremo libre destinada a alojar el extremo libre destinada a alojar el extremo de un relé. Estas muescas transversales están formadas aproximadamente en la zona central del extremo libre de dicho segundo par de brazos.The particularity of the clamp of the invention resides in the fact that at least one of said pairs of arms each includes a notch in its free end intended to accommodate the free end intended to accommodate the end of a relay. These transverse notches are formed approximately in the central area of the free end of said second pair of arms.
Adicionalmente, los extremos libres de los dos brazos de dicho primer par de brazos presentan dos resaltes paralelos que definen una pequeña acanaladura que se prolonga perpendicularmente respecto a la citada ranura de los brazos de dicho primer par de brazos y que están adaptados para alojarse en unas ranuras del cuerpo de un fusible. Con la disposición de estos resaltes, el primer par de brazos es capaz de extraer fusibles de dos tamaños distintos que, junto con los fusibles que pueden ser extraídos utilizando el segundo par de brazos, son tres los tipos distintos de fusibles que la pinza de la presente invención es capaz de manipular. La combinación de dichos resaltes y dichas muescas aporta un carácter de versatilidad a las pinzas de la presente invención puesto que con ella es posible manipular, además, relés, lo cual convierte a la pinza de la invención en una herramienta muy útil y eficaz.Additionally, the free ends of the two arms of said first pair of arms have two parallel projections that define a small groove that extends perpendicularly with respect to the said groove of the arms of said first pair of arms and which are adapted to be housed in fuse body slots. With the arrangement of these projections, the first pair of arms is capable of extracting fuses of two different sizes which, together with the fuses that can be removed using the second pair of arms, are three different types of fuses that the clamp of the The present invention is capable of manipulating. The combination of said projections and said notches provides a versatility character to the clamps of the present invention since with it it is also possible to manipulate relays, which makes the clamp of the invention a very useful and efficient tool.
De acuerdo con otra característica de la invención, los extremos libres de los dos brazos del segundo par de brazos presentan dos resaltes paralelos adaptados para alojarse en unas ranuras del cuerpo de un fusible de mayor tamaño.According to another feature of the invention, the free ends of the two arms of the second pair of arms have two parallel projections adapted to be accommodated in grooves of the body of a larger fuse.

HOJA DE SUSTITUCIÓN (REGLA 26) Para ello, los extremos (17) de los brazos (4) incluyen cada uno una muesca (25) que permite alojar un resalte longitudinal (26) del cuerpo (27) del relé (24) que de sección transversal en T. Con referencia a las figuras nos 1 y 4, el resalte longitudinal (26) puede introducirse adecuadamente por ambas muescas (25), quedando en una disposición perpendicular respecto a la ranura (18).SUBSTITUTE SHEET (RULE 26) For this, the ends (17) of the arms (4) each include a notch (25) that allows to accommodate a longitudinal shoulder (26) of the body (27) of the relay (24) that has a T-section. to figures 1 and 4, the longitudinal projection (26) may suitably be introduced by both notches (25), being in a disposition perpendicular to the slot (18).
Como puede apreciarse, el segundo par de brazos (4) está provisto por la parte exterior de dos series de nervios (28, 29) dispuestos paralelos, que sirven para facilitar el agarre de la pinza (1 ). De este modo, presionando sobre los nervios (28) se juntan los extremos (6) del primer par de brazos (3) para sujetar un fusible de tamaño mediano (7) o un fusible de tamaño pequeño (8), o bien para liberar un fusible de tamaño grande (21) o un relé (24) o bien para liberar un fusible de tamaño mediano (7) o un fusible de tamaño pequeño (8).As can be seen, the second pair of arms (4) is provided on the outside of two series of ribs (28, 29) arranged parallel, which serve to facilitate the grip of the clamp (1). Thus, pressing on the ribs (28) the ends (6) of the first pair of arms (3) are joined to hold a medium-sized fuse (7) or a small-sized fuse (8), or to release a large fuse (21) or a relay (24) or to release a medium sized fuse (7) or a small fuse (8).
Los materiales de los elementos que componen la pinza para la extracción de fusibles y relés de la invención, así como las formas, las dimensiones y demás elementos accesorios podrán ser convenientemente reemplazados por otros que sean técnicamente equivalentes, siempre y cuando no se aparten de la esencialidad de la presente invención ni del concepto inventivo de la misma definido en las reivindicaciones que se incluyen a continuación.The materials of the elements that compose the clamp for the extraction of fuses and relays of the invention, as well as the shapes, dimensions and other accessory elements may be conveniently replaced by others that are technically equivalent, provided they do not depart from the Essentiality of the present invention or the inventive concept thereof defined in the claims that are included below.
