Description

Technical Field

[0001] The utility model relates to the technical field of lead frames, in particular to a thin pad barrier 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. 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, it will be installed in the electrical appliance housing. Since the lead frame and the electrical appliance housing will be in contact, wear and tear will easily occur between the lead frame and the housing. After the lead frame is short-circuited, the metal electrical appliance housing will easily become conductive, posing a safety hazard. Utility Model Content

[0004] The utility model aims to provide a thin pad barrier type lead frame.

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

[0006] A thin pad barrier lead frame comprises a frame body, wherein the upper and lower end walls of the frame body are both provided with notches, the middle end side wall of the frame body is provided with an opening, the end wall of the frame body on one side close to the opening is provided with a through hole, sleeve pads are installed on the four corner ends of the frame body, the middle side end wall of the sleeve pad is provided with screws, a through opening is provided inside the sleeve pad, a penetration strip is installed on the inner side of the through opening, a stopper is installed on the bottom end of the penetration strip, and a rubber pad is arranged on the inner end wall of the sleeve pad.

[0007] Preferably, the notches are symmetrically distributed about the center of the frame.

[0008] Preferably, the notches and openings are symmetrically distributed about the center of the frame.

[0009] Preferably, the openings and the through holes are connected to each other.

[0010] Preferably, four sleeves are provided, and the sleeves are threadedly connected to the screws.

[0011] Preferably, the sleeve pad forms a sliding structure with the wear strip through the through opening, and the wear strip and the abutment sheet are bonded and connected, and the sleeve pad and the rubber pad are bonded and connected.

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

[0013] 1. Lubricating liquid can be added through the opening, and the lubricating liquid leaks through the perforation to lubricate the screws in the perforation, so as to prevent the screws in the perforation from rusting due to long-term use when disassembling the frame, making it difficult to unscrew and disassemble;

[0014] 2. A rubber sleeve is used for simple isolation and protection between the frame and the end wall of the electrical housing to protect the frame and prevent leakage to the electrical housing after a short circuit in the frame, which may cause danger. The through-hole and the through-bar are movable to allow the through-bar to move along the vertical direction of the through-hole to change the position of the through-bar and the abutment. The position of the abutment is controllable and adjustable, which is more flexible and convenient to use. Tightening the screws is used to lock the abutment after the position is adjusted. The rubber pad is used to make the sleeve more firmly inserted into the end side of the frame. BRIEF DESCRIPTION OF THE DRAWINGS
