This connectors provide a link between two electric conductors named trunk and electric shunt. Both, the trunk and the electric shunt, are firmly pressed against each other through the action of two different components that are set through the device that is the subject of the present invention. The present invention uses metallic cartridges with gunpowder in order to generate the energy needed to for the appliance. The cartridges are detonated by the simple act of pressing a button.
2. Description of the Related Art
Devices used for this kind of appliance are known in the art, see, for example, U.S. Pat. No. 4,722,189, BR PI 9303375-3 and BR PI 0106296-4. The first two references refer to devices that also use plastic and metallic gunpowder cartridge. In those devices the detonation is made through the use of a hammer by the user, when the hammer crashes with the back part of the device it will start the detonation of the cartridges mentioned above. The latter device listed above uses a metallic cartridge with a trigger detonation system that happens after the hand coupling by the user of the two units, after the coupling the user also has to push the trigger that will generate the detonation of the cartridge with the gunpowder.
The present invention relates to a product that gathers the advantages of the former techniques when it eliminates the interference of the user on the final result of the appliance, it's also ergometrically more favorable, its liability and productiveness are bigger, it is safer and of easy and quick handling and it has the proper power for the achievement of the objective sought. All this is accomplished through a simple push on a button connected to a pin and spring system that will start the action of a detonation needle on the metallic cartridge with gunpowder.
The invention is basically made by three main components, the first one is denominated as power unit with piston, the second one is denominated as shooting unit, and the last one as cartridge carrier, they are all firmly set with the placement of this cartridge carrier that is set with a 22 caliber metallic cartridge into the power unit. The shooting unit is threaded on the first set, therefore, forming only one set, firmly bonded, now this only set is coupled to a auxiliary head on which the connector and the conductors to be linked will be adjusted. At the threading of the shooting unit on the power unit there's a spring of detonation that is loaded inside the shooting unit, the spring is already fitted into a pin of detonation that is now in conditions of being impelled by this spring, but that doesn't happen because there's a predominant cylindrical piece supported, in it's lower part, on a second spring, blocking it.
The cylindrical piece that forms, on its upper part, the shooting button of the tool has a window passage which was made in order to allow the entrance of the detonation pin described, but only when the movement of pushing the shooting button is made. The dislocation of the shooting button extinguishes the blocking of the detonation pin that is impelled by the detonation spring, previously loaded, then it enters the window in great velocity and crashes itself against the posterior front of a detonation needle, which is also on the shooting unit. This crash will generate a small movement by the detonation needle, although enough to touch the back part of the metallic cartridge in the place where the chemical elements that will generate the detonation are lodged. The user of the tool can only use the shooting button after the lifting of a small protective and safety lid. After the detonation the user does a reverse operation unthreading the shooting unit of the power unit. The shooting unit goes back to the original position after removal. Then, the user takes of the cartridge carrier of the power unit and does a removal operation of the detonated metallic cartridge through a cleaning rod attached to the protective and safety lid, or using a loose cleaning device for the cartridge carrier.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are intended solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims.
In the drawings, wherein like reference numerals delineate similar elements throughout the several views:
As seen in the figures, the device (1) of the present invention, has a metallic piece predominantly cylindrical (2) power unit, which has on its end a thread (3) that is used for coupling with the auxiliary head (4) on the appliances operations of a electric connector (5). The power unit (2) has a smaller glove (6) and a bigger glove (7) in order to serve as a handle to make the turning operation of the power unit easier when the coupling of the auxiliary head (4). In its posterior part, the power unit (2) has a thread (8) that will be used for the coupling of the shooting unit (9). The power unit (2) has, along with it's slitting cut, a by-pass hole (10) that holds the piston (11) comprising of three diameters along its axle. During the process of the metallic cartridge (12) detonation it is pushed by the power of the explosion and expansion of the gases, allowing the effective link of the connector (5) and its respective electric conductors (13). The detonation described above is only possible because the cartridge carrier (14) is only one piece but it has two different diameters with a by-pass opening (15) that allows the introduction of the metallic cartridge (14) on its inside. The set of the cartridge carrier (14) and the metallic cartridge (12) set are fitted in the power unit (2) by its posterior part, in its by-pass hole (10), and are involved by the shooting unit (9) that when threaded on the power unit (2), through the thread (8), holds the entire set, which consists on the shooting unit (9), cartridge carrier (14) and metallic cartridge (12), power unit (2) and respective piston (11), in a only and firmly unified set. The shooting unit, in turn, has on its front a double front nut (16) which is made of to parts, with the same center (17)/(18) but two diameters, and of two internal threads (19)/(20), therefore being the connection link between the power unit (2) and the shooting unit (( ). On the back of the shooting unit (9) there's a protection rubber (21) against damage from downfall and beats on the metallic cover or main polymeric (22).
The cleaning of the cartridge carrier (14) can be done by the cleaning device consisting of a cylindrical body (24), two guide rods (25) and one cover (26). On the cylindrical body (24) there's a opening (27) for the cleaning pin (28) which will do the cleaning of the cartridge carrier (14). On the external part of the main cover (22) there's a passage window (29) that is covered with a tilter lid (30) that is locked at the fitting (31) of the lock (32) and is tilter because of the lid pin (33). The main cover (22) has a metallic or polymeric piece consisting of a shooting button (34) that has a final part standing out from the main cover (22), therefore it can be subjected to a outside action as a press or action of pushing on the transverse direction of the tool's axle by one of the fingers, that will start the de detonation of the metallic cartridge (12). The lid (30) has on it a cleaning metallic rod (35) that tilters by the pin (36), its purpose is to clean the cartridge carrier after the detonation of the metallic cartridge (12).
In summery, the appliance of the present invention and how it works, the following steps can be described:
The user couples the power unit (2) on the auxiliary head (4) where the electrical connector and its respective electrical conductor are already lodged;
Immediately after the cartridge carrier (14) has to be prepared, the metallic cartridge (12) is set on the by-pass opening (15) of the cartridge carrier (14) and, in turn, the cartridge carrier (14) is set on the by-pass hole (10) of the posterior part of the cylindrical body (59) of the power unit (2).
Then it is necessary to thread the shooting unit (9) through a thread (8) and a nut (16) on the power unit (2). During this procedure, the detonation spring (48) is loaded because the barrel (38) moves freely inside the main cover (22), in turn, the barrel (38) is guided by the guide pin (44) and the guide spring (45), therefore it pushes the detonation pin (42) against the detonation spring (48) loading it. The action of pushing the detonation pin (42) is only possible because it is lined up with the opening (47) on the posterior part of the barrel (38), this opening crosses the opening (39) in a angle of 90° degree leading the detonation pin (42) to met the wall of the shooting button (40) also fitted on the opening (39).
When the threading of the shooting unit (9) on the power unit (2) has finished the tool will be ready to be started and will be on the position showed in
After the detonation, the user will lock the lid tilter (30) and uncouple the shooting unit (9) from the power unit (2), during this movement the guide pin (44) and the guide spring (45) will place the barrel (38) forward at its initial position therefore releasing the detonation pin (57) from the window (41) of the shooting button (34) which will be impelled by the button spring (40) towards a resting position;
After the removal of the shooting unit (9) the user will remove the cartridge carrier (14) with the metallic cartridge (12) already detonated, then the cleaning of the cartridge carrier (14) will take place through the cleaning rod (35) or through the cleaning device which will allow the removal of the metallic cartridge (12) by the introduction of the cartridge carrier (14) on the opening (27), this last procedure will make the opening (15) of the cartridge carrier (14) to fit in the cleaning pin (28). At this position the posterior face of the cartridge carrier (14) where is also the face of the metallic cartridge (12) will be lined up with the lowering (67) on the cover (26), when the cover is pushed and, at the same time, guided bye the two guide rods (25) inside the guide openings (66), it will fit perfectly on the cartridge carrier (14) that will release the detonated metallic cartridge (12) by the pressure of the hands on the cover and the opposite pressure made by the cleaning pin (28). Therefore, the shooting procedures are finished.
