As shown in FIG. 1 and FIG. 2, in one embodiment of the present invention, the crimping clamp 1 of the present invention is used for crimping an end connector to one end of a wire (not shown in the figure). The crimping clamp 1 includes a pair of clamp bodies 10, a pair of jaws 20, a pair of lock mechanisms 30, a pair of stoppers 40, a pair of elastic elements 50, a pair of first locking elements 60 and a pair of second locking elements 70.
In one embodiment of the present invention, each of the clamp bodies 10 includes a holder end 11 and a head end 12. The head end 12 is connected with the holder end 11, and the head end 12 of each of the clamp bodies 10 includes a containing groove 121, a pair of perforations 122,123 and a pair of openings 124. The perforations 122,123 are respectively disposed at two corresponding sides of the containing groove 121 and communicate with the containing groove 121. The perforations 122,123 substantially correspond to each other, and an aperture of the perforations 122,123 could be the same or different. The openings 124 are also respectively disposed at two corresponding sides of the containing groove 121 and communicate with the containing groove 121. The openings 124 substantially correspond to each other. To be noted is that the number of the openings 124 can be only one. It is unnecessary that the number of the openings 124 be two or more.
In one embodiment of the present invention, each of the jaws 20 is demountably combined in the containing groove 121 of the head end 12 of each of the clamp bodies 10, and each of the jaws 20 respectively includes a hole 21 and a crimping notch 22. When each of the jaws 20 is respectively combined in each of the containing grooves 121, the hole 21 of each of the jaws 20 respectively corresponds to the opening 124 of the head end 12 of each of the clamp bodies 10. When each of the jaws 20 is respectively combined in each of the containing grooves 121, then via the clamping of the head ends 12 of the two clamp bodies 10, the crimping notch 22 of the two jaws 20 can be correspondingly combined to form a crimping groove, and the crimping groove can be used for crimping the wire and the end connector (not shown in the figure).
As shown in FIG. 2, in one embodiment of the present invention, each of the lock mechanisms 30 includes a bolt 31, a rod 32 and an operating lever 33. The bolt 31 is movably inserted in one of the openings 124. The two ends of the rod 32 respectively have inserting holes 321, 323, and one end of the rod 32 is connected to one end of the bolt 31. The operating lever 33 is movably inserted in the corresponding perforations 122,123, and one end of the operating lever 33 is connected to the one end of the rod 32 which is not connected to the bolt 31.
In one embodiment of the present invention, each of the stoppers 40 is respectively connected to one end of the operating lever 33 of each of the lock mechanisms 30 which is not connected to the rod 32. A width of each of the stoppers 40 is greater than an aperture of the perforations 122,123 or greater than the aperture of the perforation 122 but less than the aperture of the perforation 123. Each of the stoppers 40 is used for preventing the whole operating lever 33 from separating from each of the perforations 122,123 and separating from the clamp body 10.
In one embodiment of the present invention, each of the elastic elements 50 is respectively connected to the operating lever 33 of each of the lock mechanisms 30 and located between each of the stoppers 40 and the head end 12 of each of the clamp bodies 10. Each of the elastic elements 50 is used for respectively providing an elastic force to each of the operating levers 33, such that each of the operating levers 33 drives the one end of each of the bolts 31 which is not connected to the rod 32 to be inserted into the containing groove 121 of each of the head ends 12. In a specific embodiment of the present invention, the elastic elements 50 of the present invention are tension springs, but the present invention is not limited to that design.
In one embodiment of the present invention, each of the first locking elements 60 is respectively used for combining each of the operating levers 33 to each rod 32. In other words, one end of the operating lever 33 is connected to one end of the rod 32 by locking of the first locking elements 60. In a specific embodiment of the present invention, the first locking elements 60 are screws, and the operating lever 33 has a corresponding screw hole (not shown in the figure). The screw can be locked to the screw hole of the operating lever 33 after the screw passes through the inserting hole 323 of one end of the rod 32 to combine the operating lever 33 and the rod 32. To be noted is that the operating lever 33 and the rod 32 may be also integrally formed or be connected by another way. In other words, the first locking elements 60 may be omitted.
In one embodiment of the present invention, each of the second locking elements 70 is respectively used for combining each of the bolts 31 to each of the rods 32. In other words, one end of the bolt 31 is connected to the one end of the rod 32 which is not connected to the operating lever 33 by locking of the second locking element 70. In a specific embodiment of the present invention, the second locking elements 70 are also screws, and the bolt 31 has a corresponding screw hole 312. The screw can be locked to the screw hole 312 of the bolt 31 after the screw passes through the inserting hole 321 of one end of the rod 32 to combine the bolt 31 and the rod 32. To be similarly noted is that the bolt 31 and the rod 32 may also be integrally formed or be connected by another way, so the second locking elements 70 may be omitted.
Finally, please refer to FIG. 2 to FIG. 4. FIG. 3 illustrates a schematic drawing which shows the bolt of the lock mechanism inserted into the hole of the jaw; and FIG. 4 illustrates a schematic drawing which shows the bolt of the lock mechanism not inserted into the hole of the jaw.
As shown in FIG. 3, when the jaw 20 is combined in the containing groove 121, the operating lever 33 of the lock mechanism 30 drives the rod 32 to move toward a side of the head end 12 (as shown by the arrow F1 in FIG. 3) because of the elastic force provided by the elastic elements 50, so the bolt 31 can be inserted into the hole 21 of the jaw 20. At this time, the jaw 20 is fastened in the containing groove 121 because of the locking of the bolt 31, such that a user does not remove the jaw 20 from the head end 12 of the clamp body 10. When the user wants to replace the jaw 20, the user presses the stoppers 40 with his/her fingers and pushes the operating lever 33 toward the elastic elements 50 (as shown by the arrow F2 in FIG. 4), such that the operating lever 33 will drive the rod 32 away from the side of the head end 12 and the bolt 31 will depart from the hole 21 of the jaw 20. At this time, the jaw 20 is not fastened by the bolt 31, so the jaw 20 can be removed from the containing groove 121.
Via the abovementioned description, the jaw 20 of the crimping clamp 1 of the present invention is fastened by the movable bolt 31, so there is no need to use any tool to assemble or disassemble the jaw 20, which can eliminate the inconvenience of using a screw to lock the jaw 20 of the crimping clamp 1.
In summary, regardless of the function, the method and result of the present invention are shown to have technical characteristics different from the prior arts, and said method and result constitute a significant advance in the field. However, the aforementioned embodiments are just for illustration of the principle and the result of the present invention and should not be construed to limit the range of the present invention. It will be obvious to those skilled in the art that, based upon the content herein, changes and modifications may be made without departing from the spirit and scope of the present invention.
