Abstract:
1. A connector, comprising: a housing having a bottom surface mountable on an electric or electronic device and a top surface, at least one mounting groove extending from the top surface to the bottom surface, the mounting groove having a wide portion adjacent the top surface of the housing, a narrow portion between the wide portion and the bottom surface of the housing and a step between the wide and narrow portions of the mounting groove; at least one metal fixing portion mounted in the mounting groove on the housing, the metal fixing portion having opposite top and bottom ends, a solder portion at the bottom end of the metal fixing portion and connected with the device by soldering, a wide portion adjacent the top end of the fixing portion and disposed in the wide portion of the mounting groove, an intermediate portion between the wide portion of the fixing portion and the bottom end of the fixing portion, the intermediate portion being disposed in the narrow portion of the mounting groove, a step formed on the fixing portion between the wide and narrow portions thereof, the step of the fixing portion engaging the step between the wide and narrow portions of the mounting groove; and displacement restricting means formed on the narrow portion of the fixing portion for biting into the housing at the narrow portion of the mounting groove for keeping the fixing portion soldered to the device against a separating force acting on the fixing portion in a direction away from the device as the housing thermally expands, whereby the fixing portion is inserted downwardly into the mounting groove and towards the bottom surface of the housing until the step of the fixing portion contacts the step of the mounting groove for stopping the downward insertion of the fixing portion when the solder portion substantially aligns with the bottom surface of the housing.
