  • Patent number: 10044143
    Abstract: A single multi-functional position holder is positioned in a receiving space of a housing to implement multiple functions of: satisfying a limitation on the height of a connector by making contact with an insertion portion and a concentric mounting portion of a connector assembly assembled through a curling process; increasing durability to absorb an internal load attributable to the curling process, by making tight contact with the housing; and preventing shaking of a PCB assembly due to a disturbance by restricting the PCB assembly to hold a PCB, thereby reducing the number of component parts of the connector, the process steps, and the cost. In particular, the multi-functional position holder is fixed in the housing without welding so that it is possible to remove a welding process from an assembling process of the connector.
