  • Patent number: 4258971
    Abstract: A socket for a tubular bulb having a bent wire terminal at each end includes a base having a pair of spaced apart terminal contacts. Each of the terminal contacts includes an electrically conductive leaf spring and a bulb retaining member positioned inboard of the leaf spring. The bulb retaining members have bent wire terminal receiving slots and the leaf springs are biased towards each other. When the bulb is properly positioned in the socket, each of the bent wire terminals extend through its own slot in a bulb retaining member into electrical contact with the flat blade surface of a leaf spring. The biased leaf springs cooperate with the slots in the bulb retaining member to retain the bulb securely in the socket and prevent it from being accidentally dislodged.
