Description

Technical Field

[0001] The utility model relates to the technical field of lead frames, in particular to a fulcrum variable control type lead frame. Background Art

[0002] As the chip carrier of integrated circuits, the lead frame is a key structural component that uses bonding materials (gold wire, aluminum wire, copper wire) to achieve electrical connection between the internal circuit lead ends of the chip and the external leads to form an electrical circuit.

[0003] When the lead frame is in use, it will be installed in the electrical appliance housing. Due to the wide variety and different shapes of electrical appliance housings, different housings can provide different installation environments, while the size structure of the lead frame is single and fixed, resulting in poor adaptability of the lead frame when installed with different housings, and it is difficult to match them with each other.

The frame 1 is threadedly connected with the screw strip 4 through the through-hole 3. The screw strip 4 and the fixed head 5 are fixedly connected, and the fixed head 5 is symmetrically distributed about the center of the screw strip 4. By rotating the screw strip 4, the screw strip 4 is displaced in the vertical direction of the through-hole 3 to change the position of the screw strip 4.
