Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to a cable-crimping device for providing two communication connectors with different specifications being crimped by the corresponding cables. 
       BACKGROUND OF THE INVENTION 
       [0002]    At present, for conducting the signals among different electronic devices, the use of signal cables are necessary. The terminals of the signal cables must have the communication connector to plug into the connector of the electronic device. Further, since the communication connectors used by currently various communication apparatuses or electronic devices have their particular specifications, the hand tool for the cable-crimping devices must be utilized to crimp the signal cable with specific specifications into the connector with corresponding specifications, thereby the signal cable is plugged into the electronic device. 
         [0003]    Currently, the cable-crimping device is disclosed to connect the signal cable to the connector. For instance, U.S. Patent Publication No 2010/0071202 A1 entitled “CABLE-CRIMPING TOOL FOR CONNECTOR” discloses a the structure including: a first handle having a connector socket and a second handle pivoted with the first handle, a pivot portion being formed between the first handle and the second handle; a slider located between the first handle and the second handle, and including the crimping and cutting element; and a connecting rod connecting the second handle and the slider. When the first and the second handles approach to each other, the connecting rod drives the slider to move the crimping and cutting element toward the connector socket so that the connector at the socket is engaged with the corresponding signal cable. 
         [0004]    However, as to the currently rapid cable-crimping tool, the connected slider is merely driven to move due to one end of the connecting rod, and then the slider is driven to move the crimping and cutting element toward the connector socket, so as to achieve the cable-crimping operation. Therefore, the tool only provides for the connector with one kind of specification, and the usage scope is limited. The tool cannot provide for the cable-crimping operation on two connectors with different specifications. If the cable-crimping operation is performed on two connectors with different specifications, it will be accomplished by preparing two cable-crimping devices with different corresponding specifications. It is inconvenient for carrying two or more tools, and it must cost money on preparing two tools with different specifications. 
         [0005]    Furthermore, the connector socket disposed on the first handle is fixed by using the corresponding bore between the connector socket and the first handle and then engaging with the fixing dowel. Furthermore, for achieving the engagement stability, the engagement is usually performed by “tight fit”. Therefore, the socket of the cable-crimping tool only provides for the usage of a connector with one specification. If the user desires to use the connector with other specifications, the socket must be changed. As illustrated above, the current technique exists the problems on inconvenient replacement due to the “tight fit” configuration. 
         [0006]    It is therefore attempted by the applicant to deal with the above situation encountered in the prior art.

The receptacle holder  40 A accommodated with the connector  80 A and the crimping and cutting element  30 A is configured on the first handle  10 . It is also suggested that the combination portion  41 A of the receptacle holder  40 A is engaged with the positioning slot  51 A of the assembling seat  50 , and the crimping and cutting element  30 A is disposed in the crimping and cutting seat  31 A, and the slot  301 A of the crimping and cutting element  30 A is engaged with the stopper  34 A. Then, the screws  312 A fasten the crimping and cutting element  30 A and crimping and cutting seat  31 A. Therefore, for the cable-crimping operation on various connectors ( 80 A,  80 B), it is simple and convenient to replace the cable-crimping components by using one hand tool and the other cooperated dies. 
         [0049]    Please cooperatively refer to  FIGS. 3 ,  4 ,  5  and  6 , which are the cable-crimping operation on the connectors  80 ,  80 B with different specifications in accordance with the preferred embodiment of the present invention. The receptacle holder  40  with a corresponding specification is configured in the assembling seat  50  of the first handle  10  for disposing the connector  80  into the receptacle holder  40 . Another connector  80 B is inserted into the chamber  71  of the socket  70  at the second fixation portion  13 . When the second handle  101  is gripped corresponding to the first handle  10 , as shown in  FIGS. 5 and 6 , the second terminal  20 C of the first lever  22  which is actuated by the second handle  101  pushes the actuation rack  33  so as to move the crimping and cutting element  30  of the crimping and cutting seat  31  toward the connector  80 . Further, by using the crimping and cutting element  30  engaged the connector  80 , each cable  90 A can be crimped into the connector  80 . 
         [0050]    Furthermore, when the second handle  101  is pressed, the second lever  23  is actuated to simultaneously move due to the first lever  22 . The dowel  612  is removed from one end of the short groove  611  to the other end thereof due to the second lever  23 . At this moment, the press plate  60  does not move corresponding to the socket  70 . When the second lever  23  continues to move downward, the dowel  612  is engaged at the edge of the short groove  611  to drive the actuation rack  61  moved and to simultaneously drive the press plate  60  and the corresponding plate  601  moved, so that the cable  90 B is crimped into the connector  80 B. Since the route which the press plate  60  crimps into the connector  80 B is shorter than that which the crimping and cutting element  30  crimps into the connector  80  through the first lever  22 , the dowel  612  actuated by the second lever  23  is moved within the short groove  611  at the initial stage and do not push the press plate  60 . Thus, when the second handle  101  is moved to the end point toward the first handle  10 , the cable-crimping operation on the crimping and cutting element  30  to the connector  80  and the press plate  60  to the connector  80 B, respectively, can be simultaneously accomplished (referring to  FIG. 6 ). 
         [0051]    Please refer to  FIGS. 2 and 7 , when the cable-crimping device of the present invention is retrieved, the first and the second handles  10 ,  101  approach together, and the lock loop pivoted at the second fixation portion  13  of the first handle  10  is hooked on the terminal of the second handle  101 , so as to reduce the distance between the first handle  10  and the second handle  101  and easily to be retrieved. 
         [0052]    Please cooperatively refer to  FIGS. 3 ,  8  and  9 , which are the cable-crimping operation on the connector  80 A according to the preferred embodiment of the present invention.
