     Referring again to  FIGS. 1 and 2 , the shell  30  includes a top wall  31 , a bottom wall  32 , a front wall  33 , and two sidewalls  35 . The top wall  31  is substantially parallel to the bottom wall  32 . The top wall  31  defines two restricting holes  311 . The front wall  33  defines two openings  331 . Each sidewall  35  defines a clasping hole  351 . The shell  30  defines two receiving spaces  301  and two engaging spaces  303  in a back wall (not labeled) thereof. 
     Referring to  FIGS. 1 ,  2 , and  5 , the first case  60  includes a top piece  61 , a first front piece  63 , and two first side pieces  65 . The top piece  61  defines an opening  611  and a plurality of vent holes  615 . A first restricting piece  67  protrudes from a bottom surface of the top piece  61 . The first restricting piece  67  is substantially parallel to the first front piece  63 . The first front piece  63  defines two first cutouts  631 . The first restricting piece  67  defines two first indentations  671  aligned to the two first cutouts  631  one-to-one. Two first elongated ribs  673  protrude from a bounding edge of each first indentation  671 . A first restricting groove  675  is defined between the two first elongated ribs  673 . Two first restricting portions  633  are located adjacent to two respective front corners of the first case  60 . A first restricting hole  6331  is defined in each first restricting portion  633 . Two second restricting portions  651  and two first clipping pieces  653  are located adjacent to the two respective first side pieces  65 . Each second restricting portion  651  defines a second restricting hole  6511 . 
     Referring to  FIGS. 1 ,  2 ,  6 , and  7 , the second case  70  includes a bottom piece  71 , a second front piece  73 , and two second side pieces  75 . A second restricting piece  77  protrudes from a top surface of the bottom piece  71 . The second restricting piece  77  is substantially parallel to the second front piece  73 . The second front piece  73  defines two second cutouts  731 . The second restricting piece  77  defines two second indentations  771  aligned to the two second cutouts  731  one-to-one. Two second elongated ribs  773  protrude from a bounding edge of each second indentation  771 . A second restricting groove  775  is defined between the two second elongated ribs  773 . Two first hooks  733  are located adjacent to the second front piece  73  and correspond to the two first restricting holes  6331 . Two second hooks  751  and two second clipping pieces  753  are located adjacent to the respective second side pieces  75 . The two second hooks  751  correspond to the two second restricting holes  6511  of the first case  60 , and the two second clipping pieces  753  correspond to the two positioning holes  1311  of the accommodating case  10 . 
     Referring to  FIGS. 6-10 , to assemble the cable assembly, the cores  103  of the cables  100  are passed through the through hole  113  and the corresponding receiving holes  116 . The first conduction piece  211  is detached from the second conduction piece  212 . A portion of the core  103  is received between the first conduction piece  211  and the second conduction piece  212 , and the first conduction piece  211  and the second conduction piece  212  are attached together to secure the core  103  therebetween. The core  103  is electrically coupled to the conductive sleeve  20 . The insulation tubes  101  of the cables  100  are not passed through the receiving holes  116 . 
     The terminals  231  of the conductive sleeves  20  are inserted into the corresponding receiving spaces  301  of the shell  30 , with the elastic pieces  2331  inserted into the corresponding restricting holes  311 . The engaging arms  13  are inserted into the corresponding engaging spaces  303  of the shell  30 , with the clasps  133  latching in the corresponding clasp holes  351 . The rib  1331  abuts an inner side of the shell  30 . Thus, the cables  100 , the conduction sleeve  20 , and the shell  30  are assembled together. 
     To assemble the second case  70  to the accommodating case  10 , the second clipping pieces  753  of the second case  70  are inserted into the corresponding positioning holes  1311  of the accommodating case  10 , and the cables  100  are passed through the corresponding second indentations  771  and corresponding second cutouts  731 . To assemble the first case  60  to the second case  70 , the first cutouts  631  and first indentations  671  cooperatively receive the cables  100  with the second cutouts  731  and second indentations  771 , respectively. The protrusion  112  is inserted in the opening  611  of the first case  60 . The first hooks  733  latch in the corresponding first restricting holes  6331 . The second hooks  751  latch in the corresponding second restricting holes  6511 . The first clipping pieces  653  are inserted into the corresponding positioning holes  1311 . The elastic portions  135  abut inner sides of the first case  60  and second case  70 . Therefore, the cable assembly is assembled. 
     In the above cable assembly, the cores  103  are firmly received between the first conduction piece  211  and the second conduction piece  212 . Therefore, even if the cable assembly is used for a long time, the cores  103  can stay stably electrically coupled to the conductive sleeve  20 . 
     The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
