Abstract
The present invention refers to a quick connection system for electric contacts, that is, one that does not need the tightening of screws for the fixation of the conducting wire, innovative by being composed of two components, the electric current conduction metallization and the spring for the fixation of the conducting wire against the metallization, the spring being fitted in the metallization through the use of claw- shaped supports (1, 3) which pass through an opening (4) in the metallization. After the assembly, both securing tabs (2) for the conducting wire remain bent against the metallization thus ensuring the correct position of the spring after the assembly as well as the electric contact after the insertion of the conducting wire without having the spring supported in any other component.
Description
DESCRIPTION
QUICK SPRING CONNECTION SYSTEM FOR ELECTRICAL CONTACTS
Technical Field
The present invention refers to a quick connection system for electrical contacts by incorporation of a spring for fixing the direct fit conducting wire in the electric current conduction metallization without using any other components or any subsequent folding process, thus allowing a greater simplicity and modularity when compared to the existing systems in the market, as it will be described further ahead.
State of the Art
In the quick connection systems known in the market the connection between the metallization and the spring that fixes the conducting wire against said metallization is made in several different ways.
In some cases three metallic components are required: spring, electric current conduction metallization and a third one whose only function is to ensure the fixing and support of the spring in the metallization. Usually this third component comprises an area, which allows the housing of the spring as well as other areas that ensures the fixing of the spring in the metallization by fit. To ensure the fitting of the set,
the contact metallization comprises openings through which thin areas existing in the support metallization go through. After the positioning, these areas are folded in order to prevent the detachment of the set. The assembly- process referred herein implies the handling of a higher number of components when compared to the invention, apart from involving a bending process to ensure the fit.
In other cases three components are also used but, instead of a third metallic component there is a plastic support or fixation component. In these cases it is the contact metallization that comprises a spring housing area. However, the correct positioning of the spring is only guaranteed after the assembly of the set comprising the spring and metallization on the third plastic component that prevents the spring to leave the metallization. This solution implies a greater metallization complexity due to the need of a place to accommodate the spring and a third plastic component.
Another solution currently in the market is the use of spring and metallization only. Here the spring does not incorporate any specific fitting place, the metallization having a place of spring settlement. After the positioning of the spring, a fold in the metallization that traps the spring is made. This solution implies a folding process in the assembly of the set .
Description of the Invention
The quick connection system invented allows a quick installation by using a spring, which ensures the contact of the conducting wire on the electric current conduction metallization, being innovative in the solution used for its fixation (Fig. 2) , which makes the system simpler when considering several aspects that will be described further ahead, also allowing a high modularity and compact dimensions, important advantages in systems that might have little space to accommodate the referred connection system.
The present invention is characterized in that it comprises a spring (Fig.3) incorporating support places in a claw shape (1) and (3), the first of which, as well as the conducting wire securing tabs (2), is flexible. The flexion of this support (1) allows the passage of both supports through an existing opening (4) in the contact metallization (Fig.4) . After the entry of the spring and the force that causes the flexion of the claw- shaped support (1) has ended, it recovers the initial position being fitted in the metallization together with the support on the opposite side (3) , preventing the exit of the spring through said opening (4) . In addition to the flexion of the claw- shaped support (1) there is also the flexion of the tabs (2) that at the end of the proper assembly of the set are responsible for ensuring the fixing of the conducting wire against the metallization. These tabs (2) are folded along with the claw- shaped support (1) in such a way that after the fitting in the
metallization is ensured, they remain folded against the metallization at the end of the spring fitting and before the insertion of the conducting wires. Thus in a single moment, the fixation of the spring as well as the correct position of the securing tabs (2) is ensured.
By exerting force against the contact metallization, securing tabs (2) ensure the position of the claws (1) and (3) on the opposite side of the metallization immediately after the assembly and during the use of the system without the need to support the spring from bellow or sideways. In a situation in which the force of the tabs (1) and (3) against the opening sides (4) is not sufficient to ensure the accommodation of the spring or when additional stability of the set is required, there can be made, as shown on Fig. 5, recesses (5) and (6) on the periphery of the opening (4) on the sides where the claws (1) and (3) are fitted. Thus with the claws (1) and (3) entering said recesses (5) and (6) , its positioning is more stable.
As previously demonstrated, the whole conception of this system was thought to allow a simplified manufacturing process since the whole assembly of the set is figured to be easy even in a manual assembly, besides allowing the disassembly of the system if necessary, since the assembly does not imply any kind of permanent connection (riveting, bending, etc.) as in other solutions existing in the market, which is an advantage given the fact that the spring and the metallization are
processed in different materials, which implies their separation to recover the components .
As referred, this invention, by being simpler in the assembly than others, assumes a particular importance bearing in mind that all of the components involved in this type of systems present small sizes and complex shapes .
