Abstract: An electronic device includes a casing, a substrate, an electronic component, and an elastic member. The substrate is arranged inside the casing. The electronic component is arranged on the substrate. The elastic member includes a recessed portion formed to house the electronic component and a convex portion protruding toward the casing side over an entire circumference of the electronic component and being formed in an outer circumference side from the recess unit. The elastic member is compressed between the casing and the substrate.

Abstract: An electronic component mounting structure includes: a casing provided with an accommodating portion, an insertion opening formed at outside of the accommodating portion, and a threaded hole to which a screw is fastened; an electronic component including a contact terminal having elasticity; a printed circuit board having a conductor layer electrically connectable to the contact terminal; and a fixing plate provided with a fitting portion configured to fit into the insertion opening, and a screw insertion hole through which the screw is inserted, and configured to fix the printed circuit board. In the accommodating portion, the fixing plate is disposed on the printed circuit board, and the printed circuit board is disposed on the electronic component. The fixing plate is fixed to the casing by the screw inserted through the screw insertion hole in a state where the fitting portion is fitted into the insertion opening.

Abstract: An electronic device with an external connector having a body having a 1st engaged portion, a connector provided on said body, a connector cap mounted on said connector having a 1st cap engagement portion, a cover attached to said body, and having a 2nd engaged portion which engaging with said 1st engaged portion, and having a 2nd cap engagement portion catching by said 1st cap engagement portion when said connector cap is mounted on said connector.

Abstract: A mobile communication apparatus configured to be provided with an extra antenna has a printed board provided with an antenna feed point, an antenna having a spring-like contact and provided on the printed board, and a housing constituted by a first case and a second case fixed into each other. The printed board and the antenna are arranged between and pressed by the first case and the second case. The antenna feed point and the spring-like contact are in contact with and electrically connected to each other by means of elastic force of the spring-like contact caused upon the first case and the second case being fixed into each other. The housing has a space for containing the extra antenna such that the extra antenna is electrically connected to the antenna feed point by means of the elastic force.
