Abstract: A car charger includes a charger body, a cathode conducting elastic sheet and an auxiliary elastic sheet. The charger body has a housing and a holder. The cathode conducting elastic sheet has two elastic conduction arms clamped between the housing and holder. Each elastic conduction arm has a protrusion exposed out of each through hole. The auxiliary elastic sheet has two elastic sections disposed between the holder and the protrusion. The elastic sections will provide a resilience force to the protrusion when being squeezed.

Abstract: A board attachment type electrical connector is provided which can absorb an impact in the direction perpendicular to the contact parts, and through which a relatively large current can flow. Each of the flexible connecting parts in the board attachment type electrical connector has a first extension part that extends in a direction substantially parallel to the contact part after being bent from one side edge of the contact part (base plate part), and a second extension part that extends in the opposite direction from the first extension part substantially parallel to the contact part after being bent from the other side edge of the contact part. At least one of the first extension part and second extension part is connected to the board connecting part.

Abstract: An improved guidance of a plug connector in a mating connector, particularly of a cable-harness plug connector into a multipoint connector, during the insertion and positioning process, is provided. At least one recess is disposed on the mating connector and is dimensioned in such a way that, during the insertion of the plug connector into the mating connector, guide element is guided in the recess, and in the inserted state, the recess is set apart from the guide element.
