The middle portion 33 of the printed circuit board 3 is disposed in the channel (not labeled) of the front wall 2231. The positioning post 2234 disposed in the channel passes through the hole 331 of printed circuit board 3. And, as the mating portion 31 is wider than the middle portion 33, so that the mating portion 31 is stopped by the front wall 2231 of the lower cover 22 in a front-to-rear direction. One corner of the rear portion 32 of the printed circuit board 3 is supported by the supporting block and another corner of the rear portion 32 of the printed circuit board 3 is supported by the rear wall 2232 of the lower cover 22. The cables 4 extend out of the lower cover 22 through the channel of the side wall 2243 of the lower cover 22 in a left direction.
After the printed circuit board 3 and the cables 4 are together assembled to the lower cover 22, then assembling the upper cover 21 to the lower cover 22. The latch members 2237, 2244 of the lower cover 22 are respectively engaged with the wedge-shape blocks 2136, 2144 formed on the continuous side walls of the upper cover 21 so that the upper cover 21 and the lower cover 22 are latched with each other. The top end of the positioning post 2234 of the lower cover 22 is attached to the opening of circular holes 2134. The insulative housing 2 is formed after the upper cover 21 and the lower cover 22 latched with each other. Thus, the insulative housing 2 defines a main body portion (not labeled) formed by the main body portions 211, 221 of the upper and lower cover 21, 22, an upper tongue portion 212 and a lower tongue portion 222 respectively extending forwardly from the upper and lower side of the front face of the main body portion thereof.
