Title: Wiring process and wiring assembly of cable connector

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a connector, and in particular to a wiring process and a wiring assembly of a cable connector. 
     2. Description of Prior Art 
     As shown in  FIG. 1 , in a conventional cable connector, an insulating body  1   a  and a cable  3   a  are connected via a wiring assembly  2   a  by putting naked ends  300   a  of cable cores  30   a  in the cable  3   a  separately at corresponding positions of the insulating body  1   a . In this way, a soldering process or electrical connection can be performed easily. Further, some cable cores  30   a  may comprise two or more wires  31   a ,  32   a  and  33   a  that are covered by an insulating layer separately. The wiring assembly  2   a  is provided with a plurality of troughs  20   a  for allowing the wires  31   a ,  32   a  and  33   a  of each cable core  30   a  to be embedded therein. Thus, the short circuit caused by the possible contact of the naked ends  300   a  can be prevented. 
     However, in such a wiring assembly  2   a  of the cable connector, the trough  20   a  is not provided with any distinguishable or recognizable shape or indicator. As a result, when an operator intends to embed the naked ends  300   a  of each cable core  300   a  into the troughs  20   a , the operator may make mistake because he/she get confused by a great amount of naked ends  300   a . Thus, the operator may embed some naked end  300   a  into a wrong trough  20   a  easily, which makes the wiring procedure difficult and incorrect. Further, since the naked ends  300   a  have a certain length, it is difficult for the operator to embed all the naked ends  300   a  into the wiring assembly  2   a  in one time. 
     SUMMARY OF THE INVENTION 
     The present invention is to provide a wiring process and a wiring assembly of a cable connector. Due to its improved structure, the operator can disposed respective naked ends of the cable in correct positions separately. It is not necessary for the operator to embed all the naked ends into the wiring assembly in one time. Thus, the mistake made in performing the wiring process can be reduced and the assembling process can be performed more easily and correctly. 
     The present invention is to provide a wiring process of a cable connector, which includes the steps of: 
     a) providing a cable, a wiring body and a wiring plate, wherein the wiring body and the wiring plate are in a separate status; 
     b) embedding naked ends of cable into wiring ports of the wiring plate separately; and 
     c) assembling the wiring plate with the wiring body to form a single assembly. 
     The present invention is to provide a wiring assembly of a cable connector, which includes a wiring plate and a wiring body. The upper and lower edges of the wiring plate are provided with a plurality of wiring ports. The wiring body is assembled with the wiring plate. A detachable mechanism is provided between the wiring plate and the wiring body, so that the front end face of the wiring plate can be overlapped on the rear end face of the wiring body to form a single unit. By this arrangement, the wiring assembly of a cable connector can be obtained.

     DETAILED DESCRIPTION OF THE INVENTION 
     In order to make the Examiner better understand the characteristics and technical contents of the present invention, a description relating thereto will be explained with reference to the accompanying drawings. However, the drawings are illustrative only but not used to limit the present invention. 
     The present invention provides a wiring process and a wiring assembly of a cable connector. Please refer to the step S 1  in  FIG. 2  and also refer to  FIG. 3 . First, a cable  3  and a wiring assembly  2  of a cable connector are provided. The wiring assembly  2  comprises a wiring body  21  and a wiring plate  20  that are detachably assembled with each other. The cable connector further includes a connecting head  1 . The connecting head  1  comprises a casing  10  and an insulating body  11  provided in the casing  10 . The insulating body  11  is connected to the wiring body  21  of the wiring assembly  2 , so that all these components can be assembled in the casing  10 . Further, a detachable mechanism  22  is provided between the wiring plate  20  and the wiring body  21  of the wiring assembly  2 . The detachable mechanism  22  is composed of two insertion holes  220  on the front end face of the wiring plate  20  and two corresponding insertion pins  221  on the rear end surface of the wiring body  21 . After the insertion pins  221  insert into the insertion holes  220 , the front end face of the wiring plate  20  touches the rear end face of the wiring body  21 , thereby forming a detachable assembly. By means of the detachable assembly, the wiring plate  20  can dovetail with the wiring body  21 . Of course, the positions of the insertion holes  220  and the insertion pins  221  can be exchanged. 
     Next, please refer to the step S 2  in  FIG. 2  and also refer to  FIG. 4 . Naked ends  300  of each cable core  30  of the cable  3  are separately embedded into wiring ports  200  provided on the upper and lower edges of the wiring plate  20 . Thus, the operator can make the originally-disordered cable cores  30  in order. 
     Please refer to the step S 3  in  FIG. 2  and also refer to  FIG. 5 . The wiring plate  20  is assembled with the wiring body  21  to form the wiring assembly  2 . That is, via the detachable mechanism  22  between the wiring plate  20  and the wiring body  21 , the wiring plate  20  can be assembled on the rear end face of the wiring body  21 . Since the respective cable cores  30  of the cable  3  are put in order after the step S 2 , the length of each naked end  300  is partially embedded into the wiring plate  20 . As a result, the remaining part of each naked end  300  can be disposed on the wiring body  21  more easily and correctly. Thus, the wiring process can be completed. Then, the terminals in the casing  10  can be soldered to generate electrical connection ( FIG. 6 ). 
     Via the above arrangement, the wiring process and the wiring assembly of a cable connector according to the present invention can be obtained. 
     According to the above, the present invention really achieves the expected objects and solves the problems of prior art. Further, the present invention demonstrates novelty and inventive steps, which conforms to the requirements for an invention patent. 
     Although the present invention has been described with reference to the foregoing preferred embodiment, it will be understood that the invention is not limited to the details thereof. Various equivalent variations and modifications can still occur to those skilled in this art in view of the teachings of the present invention. Thus, all such variations and equivalent modifications are also embraced within the scope of the invention as defined in the appended claims.
