However, the assembly structures 110 and 114 are designed in such a way that the edge 109 does not contact the shoulder 116 of the assembly structure 114. This creates a clearance 126 in communication with the interior of the assembled housings 102 and 104. The contact surfaces 132 and 134 in contact with each other define a contact interface 136 between the front housing 102 and the rear housing 104. More specifically in this embodiment, the contact interface 136 includes an edge 111, one side of the shoulder 116 and two sides of the shoulder 112. As the slots 120 are disposed in the contact surface 134, the contact interface 136 is locally disconnected by gaps 122 and 124 formed along the contact interface 136. Thus, the gaps 122, 124, 126 provide a plurality of ventilation passages 138 for efficiently dissipating heat.
