Portable telephone

Electromagnetic shielding apparatus for portable telephones (300) and other electronic equipment, includes shield clips (100) for intercoupling the conductive surfaces of a housing (302 and 303) to the metal layer (205) of the circuit board (200). Each shield clip (100) mates with a corresponding edge (204) of the circuit board (200) such that tabs (208, 209, 210) insert into holes (108, 109, 110) in the central channel (111--113) of the clip (100) and feet (101, 102, 103) of the clip rest on other tabs (201, 202, 203). The clip (100) is bonded to the metal layer (205) of the circuit board preferably by resistance welding, thereby reliably connecting the clip (100) and the conductive housing surfaces to signal ground.

A housing for miniature electronic equipment is disclosed. A mechanical fastening system is utilized in holding front and rear portions of the housing together without conventional fasteners. The front housing portion has cantiliever beam spring catches which penetrate slots in the rear housing and captivate the rear housing and internal components. The spring catches are fixed in position by supporting rails of a detachable battery.

Mechanical fastening system for an electronic equipment housing

A battery housing with an integral latch and a cantilevered spring finger positive displacement mechanism is disclosed. The slide-on battery is captivated by guide rails on each side of the mating surface of the battery housing. When the battery is properly located, a torsion bar latch locks the battery in place. When the latch is activated by the user to remove the battery, cantilevered spring fingers force the battery housing away from its locked position.
