There are two holes 126 located in lateral sides of a bottom wall of the bottom cover 12. A number of positioning cavities 127 are located in a lower side of the bottom cover 12.
There are six second openings 110 located in a front wall of the top cover 11. A number of first positioning posts 112 are located on a front segment of an upper wall of the top cover 11 and inserted into the first positioning holes 124 respectively. There are several second positioning posts 111 are located on a back segment of an upper wall of the top cover 11 and inserted into the second positioning holes 125 respectively. Three semi-circular cable outlets 113 are defined in a back wall of the top cover 11 and cooperate with the cable outlets 122 to form corresponding circular cable outlets to allow the cables 4 passing through. Two latching arms 114 are formed at lateral sides of the upper wall of the top cover 11 and locked into the holes 126 so as to keep the top cover 11 and the bottom cover 12 together. A number of positioning cavities 115 are located in an upper wall of the top cover 12. A number of windows 116 are defined in the upper wall of the top cover 12.
The connectors 2 are accommodated in the grooves 120, respectively. The connectors 2 include several first connectors 21 and second connectors 22. The first connectors 22 include four USB connectors which have similar structure as commonly used type, i.e. USB 2.0. The second connectors 21 have two Audio jacks which have similar structure as commonly used type. Both the first connectors 21 and the second connectors 22 are electrically coupled to the cables 4.
Each first connector 21 includes a terminal module 210 and a metallic shell 211 enclosing the terminal module 210. The terminal module 210 and the metallic shell 211 together define a mating port 212 exposed outside of the insulative cover 1. The metallic shell 211 has an expanded front end 213. The terminal module 210 has a dielectric body 214 and a plurality of terminals 215 retained with the dielectric body 214. Each terminal 215 has a tail portion 2150 backwardly projecting outside of the dielectric body 214 to be connected with the cable 4. Detailed description of the second connector 22 is omitted hereby.
The conductive member 3 is made of metal sheet. The conductive member 3 is an inverted L-shaped viewed from a back side. The conductive member 3 has a horizontal portion 31 and a vertical portion 32 joining with a lateral edge of the horizontal portion 31. There is a first tab 311 formed on the horizontal portion 31 and obliquely and upwardly extending therefrom. There is a second tab 321 formed on the vertical portion 32 and obliquely and upwardly extending therefrom. The first tab 311 is disposed above and supported by the horizontal portion 31. The second tab 321 is disposed under the horizontal portion 32. The first tab 311 and the second tab 321 are respectively punched from the horizontal portion 31 and the vertical portion 32, therefore there two holes 310, 320 left when they are deflected from original positions.
