Description

Technical Field

[0001] The utility model relates to the technical field of lead frames, in particular to an angled positioning 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 positioned in the electrical housing by screws. Since the internal shapes and structures of different electrical housings are different, and ordinary lead frames are mostly rectangular, threaded holes will be opened at the four corners of the lead frame. When positioning, the screws will often be inserted vertically into the lead frame, and the positioning direction is fixed. As a result, when the lead frame is positioned and installed, it is difficult to assemble with the housing with inclined internal positioning holes, and the adaptability is poor during installation and positioning. Utility Model Content

[0004] The utility model aims to provide a folded-angle positioning lead frame.

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

[0006] A corner positioning lead frame comprises a frame body, wherein both front and rear ends of the frame body are provided with solid blocks, a support and a threaded rod are penetrated in the middle of the solid block, both left and right end walls of the frame body are penetrated with through openings, a slide rail is installed on the end side of the frame body close to the through opening, a slide seat is installed on the end side of the slide rail, a rubber pad is arranged on the end wall of the slide seat away from the slide rail, notches are penetrated in the four corner end walls of the frame body, a rotating shaft is installed in the middle part of the frame body close to the notch, a rotating sheet is installed on the end of the rotating shaft away from the frame body, and a sheet hole is penetrated in the end wall of the rotating sheet.

[0007] Preferably, the frame and the solid block are fixedly connected.

[0008] Preferably, the solid block and the threaded rod are threadedly connected, and the support and the threaded rod are fixedly connected.

[0009] Preferably, the frame and the slide rail are fixedly connected, and the frame forms a sliding structure through the slide rail and the slide seat.

[0010] Preferably, the sliding seat and the rubber pad are bonded to each other, and the rubber pads are distributed at equal distances with respect to the end wall of the sliding seat.

[0011] Preferably, the frame is rotatably connected to the rotating plate via a rotating shaft, and four rotating shafts and four rotating plates are provided, and the end walls of the rotating plate and the notch are both arc-shaped.

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

[0013] 1. By rotating the threaded rod, the threaded rod is displaced along the vertical direction of the solid block, changing the position of the threaded rod and the support. The support is used to support the top and bottom of the frame to prevent the other electrical components and circuit boards of the electrical housing from loosening and contacting the frame, thus achieving a simple barrier protection effect;

[0014] 2. By rotating the shaft, the rotating piece rotates around the axial direction of the shaft, changing the direction of the rotating piece. The direction of the hole is controllable and adjustable, which is more flexible when positioning the hole and inserting the screws. The adaptability of the frame positioning is improved, so that the frame can be installed in a shell with a more complex shape and structure. The hole on the end wall of the rotating piece is used to insert the screws to position the frame in the electrical housing. The four rotating shafts are symmetrically arranged at the four end corners of the frame. When the hole on the end wall of the four rotating pieces is positioned in the electrical housing by screws at the same time, the rotation characteristics of the shaft will be limited and self-locking.

[0025] Embodiment 2:

[0026] Based on the first embodiment, Figure 1 and Figure 2 As shown, the frame 1 and the solid block 2 are fixedly connected, the solid block 2 and the threaded rod 4 are threadedly connected, and the support 3 and the threaded rod 4 are fixedly connected. The frame 1 and the slide rail 6 are fixedly connected, and the frame 1 forms a sliding structure through the slide rail 6 and the slide seat 7. The threaded rod 4 is rotated to displace the threaded rod 4 along the vertical direction of the solid block 2, and the positions of the threaded rod 4 and the support 3 are changed. The support 3 is used to support the top and bottom of the frame to prevent the remaining electrical components and circuit boards of the electrical housing from loosening and contacting the frame, which plays a simple barrier protection effect. At the same time, the slide rail 6 and the slide seat 7 are movable to allow the slide seat 7 to displace along the length direction of the slide rail 6. The position of the slide seat 7 is controllable and adjustable, and the rubber pad 8 of the rubber material of the end wall of the slide seat 7 is used to buffer and protect the side end of the frame, which plays a simple protection purpose of the frame.

[0027] Based on the first embodiment, Figure 3 and Figure 4As shown, the slide 7 and the rubber pad 8 are bonded and connected, and the rubber pad 8 is equidistantly distributed about the end wall of the slide 7. The frame 1 is rotatably connected to the rotating piece 11 through the rotating shaft 10, and the rotating shaft 10 and the rotating piece 11 are each provided with four, and the rotating piece 11 and the end wall of the notch 9 are both arc-shaped. By rotating the rotating shaft 10, the rotating piece 11 rotates around the axial direction of the rotating shaft 10 to change the direction of the rotating piece 11. The direction of the sheet hole 12 is controllable and adjustable. When the sheet hole 12 is positioned to pass through the screw part, it is more flexible, and the adaptability of the frame during positioning is improved, so that the frame can be installed in a shell with a more complex shape and structure. The sheet hole 12 on the end wall of the rotating piece 11 is used to pass through the screw part to position the frame 1 in the electrical housing. The four rotating shafts 10 are symmetrically arranged at the four end corners of the frame 1. When the sheet holes 12 on the end walls of the four rotating pieces 11 are simultaneously positioned in the electrical housing by screws, the rotation characteristics of the rotating shaft 10 will be limited and self-locking.

[0028] Working principle: By rotating the threaded rod 4, the threaded rod 4 is displaced along the vertical direction of the solid block 2, changing the position of the threaded rod 4 and the support 3. The support 3 is used to support the top and bottom of the frame to prevent the other electrical components and circuit boards of the electrical housing from loosening and contacting the frame, which plays a simple barrier protection effect. At the same time, the slide rail 6 and the slide seat 7 are movable to allow the slide seat 7 to displace along the length direction of the slide rail 6. The position of the slide seat 7 is controllable and adjustable, and the rubber pad 8 of the end wall of the slide seat 7 is used to buffer and protect the side end of the frame, which plays a simple role of protecting the frame. By rotating the rotating shaft 10, The rotating piece 11 rotates around the axial direction of the rotating shaft 10 to change the direction of the rotating piece 11. The direction of the sheet hole 12 is controllable and adjustable. When positioning the sheet hole 12 and inserting the screw, it is more flexible, which improves the adaptability of the frame when positioning, and allows the frame to be installed in a shell with a more complex shape and structure. The sheet hole 12 on the end wall of the rotating piece 11 is used to insert the screw to position the frame 1 in the electrical housing. The four rotating shafts 10 are symmetrically arranged at the four end corners of the frame 1. When the sheet holes 12 on the end walls of the four rotating pieces 11 are positioned in the electrical housing by screws at the same time, the rotation characteristics of the rotating shaft 10 will be limited and self-locking.
