A pendant mounting structure comprises a main body, a hook and two latching elements. The main body includes an upper surface and opposite side surfaces perpendicular to the upper surface and positioned at two side of the main body. The hook protrudes from the upper surface. The latching elements protrude from two sides of the main body. The pendant mounting is separately manufactured and latched to a housing. Thus, when an external force exerted on the hook is more than the structural limit of the hook, the hook could be break to protect the housing from damage.
