Description

Technical Field

[0001] The utility model relates to the technical field of lead frames, in particular to an anti-contact 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. It serves as a bridge to connect to external wires. Lead frames are required in most semiconductor integrated blocks and are an important basic material in the electronic information industry.

[0003] When the lead frame is in use, generally multiple lead frames are installed in the casing of the electrical appliance. When multiple lead frames are installed close to each other, the lead frames are prone to touching each other. When the lead frame is inside the casing, when the casing falls, is shaken during handling, etc., the lead frame is prone to wear and short circuit, posing a major safety hazard. Utility Model Content

[0004] The utility model aims to provide an anti-contact lead frame.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A contact-proof lead frame comprises a frame plate, the four corner end walls of the frame plate are all provided with openings, the end wall of the frame plate close to the opening is penetrated with a through hole, a fixing plate is installed on the inner side of the opening, a fixing seat is installed on the bottom end of the fixing plate, a seat hole is penetrated inside the fixing seat, a resisting plate is installed on the bottom end of the fixing seat, a screw is arranged on the end wall of the resisting plate close to the fixing seat, a pillar is installed on the upper end of the fixing plate, a cross frame is arranged on the top end of the pillar, and a rubber sleeve is installed on the end side of the cross frame.

[0007] Preferably, the openings are symmetrically distributed about the center of the through-hole, and the number of the openings is twice the number of the through-holes.

[0008] Preferably, the openings and through-holes are symmetrically distributed about the center of the frame plate.

[0009] Preferably, the opening is rectangular, and four openings are provided.

[0010] Preferably, the fixed plate is fixedly connected to the fixed seat and the pillar, and four fixed seats are provided, and the screw rod is fixedly connected to the abutment plate.

[0011] Preferably, the fixed seat is threadedly connected to the screw rod through the seat hole, and at the same time, the support column and the cross frame are fixedly connected, and the cross frame and the rubber sleeve are adhesively connected.

[0012] The utility model has at least the following beneficial effects:

[0013] 1. The fixed seat is inserted through the through hole, the opening on the upper end of the through hole is inserted into the fixed plate, and the opening on the lower end of the through hole is used to place the contact plate. When the contact plate rotates, the screw is screwed into the seat hole of the fixed seat, and the fixed seat, the contact plate and the screw are firmly connected to each other to form a whole;

[0014] 2. The through-hole and the fixing seat are both rectangular in shape. After the fixing seat is rotated 180 degrees, the fixing seat is inserted into the through-hole to turn the cross frame fixed together by the pillars on the top of the fixing seat so that the cross frame stands on the outside of the end corner of the frame plate. At this time, when two frame plates or more frame plates are installed close to each other in the same electrical housing, the frame plates are blocked by rubber sleeves to prevent contact between the frame plates, between the frame plates and sharp objects in the housing, and between the frame plates and the sharp outer walls of electronic components installed on another frame plate, thereby reducing the risk of short circuit caused by wear of the frame body and contact between the metal copper foil on the frame.
