     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a cable end connector, and more particularly to an installation structure of the insulative body and the spacer. 
     2. Description of Related Arts 
     China Patent No. 203481412, issued on Mar. 12, 2014, discloses an electrical connector including an insulative body, a number of terminals received in the insulative body, a cable electrically connected to the corresponding terminals, a spacer assembled to the back end of the insulative body, and an insulative housing molded to enclose the insulative body and the spacer. The back end of the insulative body is designed to have a ladder shape. However, an interference will be present between the spacer and the insulative body during mounting the spacer to the insulative body, resulting in inconvenience of the installation. 
     An improved connector is desired to offer advantages over the related art. 
     SUMMARY OF THE INVENTION 
     An object of the present invention is to provide a cable end connector for ease of mounting of a spacer thereof. 
     To achieve the above-mentioned object, a cable end connector includes an insulative body, a number of terminals received in the insulative body, a spacer mounted behind the insulative body, and an insulative housing molded to enclose the inuslative body and the spacer. The spacer includes an intermediate chamfer at a mounting end thereof to prevent interference during mounting of the spacer to the insulative body. A stopping wall is disposed at two opposite sides of the chamfer to prevent molten plastics from flowing into the insulative body during molding the insulative housing. 
     According to the present invention, the spacer includes a chamfer to avoid the interference between the spacer and the insulative body. The stopping walls are disposed on two sides of the chamfer to prevent the molten plastic from flowing into the insulative body to influence the electrically connection of the connector.

     Referring to  FIGS. 2 to 5 , the insulative body  1  comprises a main portion  11  and an extending portion  12  extending from the main portion  11  to the cable  200 . The extending portion  12  has a ladder shape. The extending portion  12  of the insulative body  1  comprises a fan slot  121 . A plurality of terminal holes  13  are disposed on the insulative body  1  for being inserted by the terminals  2 . A surface of the insulative body  1  which is mating with the spacer  3  comprises a first mounting hole  14  and a pair of second mounting holes  15  recessing inwardly. Two sides of the first mounting hole  14  are disposed one second mounting holes  15  respectively. The first mounting hole  14  and the second mounting holes  15  are on three points of a triangle to make the spacer  3  fixed firmly on the insulative body  1 . 
     The terminals  2  comprise a number of first terminals  21 , a number of second terminals  22 , and a number of third terminals  23 . Each third terminal  23  comprises a contacting portion  231  received in the insulative body  1  for mating with a mating connector, a soldering portion  232  extending out of the insulative body  1  soldering with the core wires (not shown), and a connecting portion  233  connected the contacting portion  231  and the soldering portion  232 . 
     Referring to  FIGS. 4 to 6 , the spacer  3  mounted on the extending portion comprises a first spacer  31  and a second spacer  32 . The first terminals  21  and the second terminals  22  are held in the first spacer  31 , and the third terminals  23  are held in the second spacer  32 .
