The second inner sidewall 112 has a second straight surface 1122 that is perpendicular to the circuit board 102 and a second oblique surface 1124 that is non-perpendicular to the circuit board 102. In the present embodiment, the first inner sidewall 110 further includes a third oblique surface 1106 and a fourth oblique surface 1108 that are not perpendicular to the circuit board 102. The third oblique surface 1106, the first straight surface 1102, the first oblique surface 1104, and the fourth oblique surface 1108 extend sequentially from the opening of the slot 108 to the bottom support surface 114. The second angled surface 1124 and the second straight surface 1122 extend sequentially from the opening of the slot 108 to the bottom support surface 114. Additionally, the bottom support surface 114 is substantially parallel to a surface 1022 of the circuit board 102, and the connector 100 is disposed on the surface 1022 of the circuit board 102.

In accordance with an embodiment of the present invention, the first straight surface 1102 is parallel to the second straight surface 1122, and the first oblique surface 1104 is parallel to the second oblique surface 1124.
