Abstract

The utility model discloses a small-space spring-piece contact structure which is used for an adaptor and capable of connecting conductive connecting pieces between PINs and a PSIP without welding and occupies a small space in a casing. Z-shaped elastic conductive connecting pieces are arranged in gaps between inner ends of the PINs at the inner face of a lower cover and the PSIP at the bottom part and the conductive connecting pieces make full use of idle space in the casing of the adaptor, that is, the gaps between the PSIP and the inner surface of the lower cover and cling closely to the inner side of a flange of the lower cover. Therefore, the adaptor can be made to be smaller in volume. Moreover, lower flat pieces of the conductive connecting pieces are buckled and fixed with the PINs through clamping holes and upper flat pieces of the conductive connecting pieces get across the PSIP plate in an elastic method to connect a circuit board above. During assembly, only the lower flat pieces need to be buckled on the PINs and then the PSIP presses the lower flat pieces. The structure is not only capable of preventing environment pollution caused by welding, but also capable of reducing welding personnel so that the manpower cost is reduced significantly.
