Description

The present utility model belongs to applicator tools in general, and more specifically to a compression tool for applying terminals/splices attachable to an impact wrench which, according to its general characteristics, has as its basic principle to provide the formation of a compression tool in its own and specific structure of universal type, attachable to an impact wrench and based on the integration of an applicator body with a threaded hole, a lead screw and a sliding compression die, in order to allow, in an extremely practical, safe and precise way, a complete optimization in the set of mechanical and manual procedures for applying compression to terminals and splices of conductors of electric power distribution networks and other electric power networks by using impact wrenches, combined with the absence of wear and tear on conductors, terminals and splices and improvements in the maintenance of electric power distribution networks and, having as a basis, a compression tool with great strength, safety and versatility. With a specific and easily accessible design and format for better adaptation and user safety, practical handling and functionality, very affordable and, due to its general characteristics and dimensions, easily adaptable to a wide range of terminals, splices, power conductors, impact wrenches, locations, and technicians in general, regardless of the characteristics they may present. Currently, one of the main problems in the maintenance of low and medium-voltage power network branches are the electrical connections between the power cables/conductors, which are usually made by means of splices, as well as cable terminations which are made by means of terminals. Electrical terminals and splices are components used to make reliable connections between conductors and other electrical system elements. They ensure the continuity of circuits and the safety and quality of electrical networks or installations. To meet the needs of companies and their technicians, as well as the most diverse types of projects, numerous models of electrical terminals are available. In simple terms, an electrical terminal or splice is the component that connects a device or accessory to power conductors, and its main characteristic is its versatility since it is easily found in the most varied shapes and sizes. Therefore, electrical terminals can be defined as the components responsible for bridging two power conductors, which can be found in circuit breakers, meters, terminals, and relays, among others. To understand how these components work, it is necessary to remember that these electrical components are made of electrically conductive material, such as electrolytic copper or aluminum, and the cable is usually fixed by compression. In such cases, a skived tip is inserted inside the terminal and then the tube where the cable is located is compressed using special pliers. It should be noted that power conductors are considered essential components in any installation or equipment as they are the ones responsible for carrying electrical power from one point to another. Power conductors allow the safe and effective distribution of power, thus ensuring the supply of the electrical load in various situations. Within this scenario, it is often necessary to expand the area of electrical power operation by splicing power conductors to ensure transmission to other points. This type of operation is so important that there is a regulatory standard that establishes all the conditions for splicing power conductors, so that splicing power conductors is the operation that consists in joining two or more conductors whose purpose is to extend or derive these same conductors. Today, different models of tools for the installation and application of terminals and splices on power conductors adapted to truck hydraulics or manual or portable hydraulic pumps are widely known in the state of the art. Among these, some commercial solutions found in the market are presented, with the main manufacturers being Burndy, Greenlee, Huskie, Sanwa Tekki Co. Cembre. More specifically, manual hydraulic tools for terminal presses—pliers, where the main difference is the price and the applicable maximum loads of the covered diameters, with Alimaq, Burndy and Ahb as the main manufacturers; hydraulic compression tools for terminal presses adaptable to fluid pumping systems that can be semi-automatic (manual fluid pumping) or automatic, using truck hydraulics or an external hydraulic pump system (an independent unit), with Burndy and Greenle as the main manufacturers; and automatic hydraulic tools for terminal presses, with Burndy and Alimaq as the main manufacturers; are widely known and used. In an extensive review of the literature in order to provide the current state of the art of tools for applying compression to connectors, terminals and splices on power conductors, object of the present utility model, documents relevant to the prior art dis
