Communication device

A communication device comprising:

• a housing assembly comprising a bottom cover, a mounting bracket and at least one positioning component, the mounting bracket movably disposed on the bottom cover, the mounting bracket movable relative to the bottom cover between an installation position and a pre-installation position via a guiding structure, the at least one positioning component connected to the bottom cover, and the at least one positioning component configured to fix the mounting bracket in the installation position in a detachable manner;
• a heat dissipation module fixed to the bottom cover, the heat dissipation module having a heat-absorbing surface, and the mounting bracket being located farther away from the heat-absorbing surface when in the pre-installation position than in the installation position;
• and
• a communication main unit detachably disposed on the mounting bracket;
• wherein when the mounting bracket is in the installation position, the communication main unit is in physical contact with the heat-absorbing surface of the heat dissipation module;
• wherein the communication main unit has an engagement hole, the housing assembly further comprises an engagement protrusion fixed to the mounting bracket, the engagement hole is a keyhole slot, the engagement hole comprises a wide part and a narrow part that are connected to each other, a width of the wide part is larger than a width of the narrow part, the engagement protrusion comprises a head part and a neck part that are connected to each other, the neck part is fixed to the mounting bracket and located between the head part and the mounting bracket, a width of the head part is larger than a width of the neck part, and the width of the head part is smaller than the width of the wide part and larger than the width of the narrow part, and the width of the neck part is smaller than the width of the narrow part;
• wherein after the head part of the engagement protrusion passes through the wide part of the engagement hole, and the neck part is disposed through the wide part, the communication main unit can be moved relative to the mounting bracket along an engaging direction parallel to the heat-absorbing surface for moving the neck part from the wide part to the narrow part and engaging the engagement protrusion with the narrow part of the engagement hole.
