A mobile phone includes an external power supply terminal receiving power from the external power supply, a secondary battery charging at least part of the received power and supplying the charged power to a load, a radio circuit receiving power from the secondary battery and allowing transmission power to be varied, and a control portion detecting the transmission power level of the radio circuit and switching to any of a plurality of charge modes having different time periods for charging the secondary battery, based on the detected transmission power level.

Mobile communication terminal driven by power received from secondary battery, charge mode switching method and charge mode switching program executed in mobile communication terminal

A connector used for a plurality (plural kinds) of memory cards is provided in which contacts can easily be assembled and contact leads can rapidly be inspected visually. A housingis covered with a coverso that a card holding partis formed that has a card insertion portshared by an SD cardand a Memory Stick card. The SD cardstops at a position near the card insertion port, while the Memory Stick cardstops at a position distant from the card insertion port. Cantilever contactshave first contact pointsfor contacting with surface contact terminalA, while first lead partsextend out from a stopper. Cantilever contactshave second contact pointsfor contacting with surface contact terminalA, while second lead partsextend out from the stopper. A plurality of the first lead partsand a plurality of the second lead partsextend out in parallel to each other from the stopper

A PC card can reduces possibility of the lid being detached from the extended portion even when twisting stress, bending stress, etc. is applied against the PC card, and simplifies the metal mold for resin molding. In the PC card, by placing a lid so as to face an extended portion in such a way that catches provided on the lid are evaded from the catches provided on the extended portion, and thereafter sliding the lid relatively against the extended portion in parallel with the insertion direction to the electronic apparatus, the catches on the lid and the catches on the extended portion become aligned in the height direction, and thereby the lid is fixed to the extended portion.

A connector with a switch comprises a housing for defining a terminal accommodation chamber opened through a plug pin insertion hole. A fixed terminal and a switch terminal are held by the housing. The switch terminal comprises a U-shaped section opened toward the plug pin insertion hole in the terminal accommodation chamber. The U-shaped section is elastically deformable in a direction crossing the direction of plug pin insertion. The switch terminal is switched from a state in which it is brought into contact with the fixed terminal to a state in which the contact thereof with the fixed terminal is cut off as the U-shaped section is deformed in the direction crossing the direction of plug pin insertion.

Coaxial connector with a substantially S-shaped switch

A connector, which enables the molding of narrow press-fitting grooves for cantilever contacts and has cantilever contact press-fitting grooves of a structure such that the molding dies for the grooves will have adequate strength and durability, is provided. In molding a rectangular first press-fitting groove, in which a first fixed partB of a cantilever contactis press-fitted, a plurality of upper-face opened recess partsU, which are continuous with the first press-fitting groove, are molded by an upper die. Lower-face opened recess partsD, which are continuous with the first press-fitting groove, are molded by a lower die. By the combination of the upper dieand the lower die, the upper-face opened recess partsU and the lower-face opened recess partsD are formed in an alternating manner. The first press-fitting grooveis formed in an intermittent manner by the upper-face opened recess partsU and the lower-face opened recess partsD.

The present invention provides a connector capable of being easily and reliably coupled to a printed circuit board. A connector () comprises two sets of a plurality of lead parts () and a plurality of lead parts () extending from one side surface () of a housing () to be opposite to each other. A printed circuit board () includes slot () abutting on the side surfaces () to () of the housing (), and edge connectors (A) and (B) are formed on both surfaces of an edge abutting on the one side surface (). The edge connectors (A) and (B) are inserted between the lead parts () and (), and the lead parts () and () are soldered to the edge connectors (A) and (B), respectively. In a pair of first protrusions (A) and (B), a recess () for gripping the printed circuit board () is formed, and the recess () is aligned in the same row as the opposing gap between the lead parts () and (), The second protrusions (A) and (B) each have a supporting surface abutting on one surface of the printed circuit board (), and respectively protrude from the side surfaces () and () arranged opposite to each other.
