Abstract: An interchangeable plug charger with a coaxial conductive structure includes a charger body and a plug assembly. The charger body has a retaining surface inside, and the retaining surface has a first conductive terminal and a second conductive terminal. The plug assembly is detachably connected to the charger body and includes a plug socket and the coaxial conductive structure. The coaxial conductive structure includes a hollow insulating column, a first conductively connected component sheathed on the hollow insulating column, and a second conductively connected component connected to the interior of the hollow insulating column. The first conductively connected component is electrically connected to the first conductive terminal, and the second conductively connected component is electrically connected to the second conductive terminal. Therefore, the size of the charger can be reduced and the structure of the charger can be simplified to improve the convenience of carrying and use.

Abstract: A charger includes a first housing, a second housing connected with the first housing, and a PCB assembled between the first and second housings. The first housing is defined with a plurality of battery chambers. Each battery chamber is assembled with first and second resilient plates for respectively contacting positive and negative poles of a rechargeable battery. Each resilient plate has a contact portion and a soldering portion. A circuit system is defined at the PCB and includes an AC-DC circuit, a charging circuit, and a power output and input circuit. The circuits are connected with each other and connected with the soldering portions of the first and second resilient plates of each battery chamber. A power input socket and a power output socket are formed to connect with the power output and input circuit.

Abstract: A card connector has an insulative frame, a plurality of conductive terminals received in the insulative frame, an eject device assembled on the insulative frame and a shell covering the insulative frame. The eject device includes a driving rod, a driven shaft, a driven sleeve, a slider and a resilient element. The driving rod axially defines a 90 degree first continuous chute, and the driven shaft axially defines a 90 degree second continuous chute for meshing with the first continuous chute. The driven sleeve is fixed on the insulative frame and telescopically meshes with the driven shaft. The slider is cantileveredly mounted on the driving rod. During insertion of the card, the driving rod drives the driven shaft to rotate. A stop block of the driven sleeve disengages from an abutting portion of the slider, and thereafter engages with a wedging hole of the card. Thus, the card in final position is protected against exterior reverse shock.
