An etched lead frame

Abstract

This utility model discloses an etched lead frame, relating to the field of lead frame technology. It addresses the problems of etched lead frames being easily affected by the internal structure of electrical appliance housings, leading to installation limitations, and being prone to wear due to contact with the electrical appliance housing during use. The design includes a frame body, horizontal slots at both ends of the frame body, and vertical slots on both sides of the frame body. Each of the horizontal and vertical slots is equipped with a protective mechanism. This utility model uses a rotating block to drive a bidirectional screw to rotate, which in turn drives a moving plate to move a positioning rod. The positioning rod separates from the positioning hole, allowing adjustment of the moving block's position. After the positioning rod is reinserted into the positioning hole, the adjusted moving block is locked.

The cooperation between the arc-shaped guide rod and the mounting plate allows the frame body to flexibly adapt to the installation space inside the electrical appliance housing when fixed.

Description

Technical Field

[0001] This utility model relates to the field of lead frame technology, specifically an etched lead frame. Background Technology

[0002] Etched lead frames are a key structural component in semiconductor packaging, mainly used for packaging integrated circuit chips. They form precise circuit patterns on a thin metal sheet through chemical etching, enabling electrical connections between the internal circuitry of the chip and external leads.

[0003] In existing etched lead frame technology, the lead frame is positioned inside the electrical housing using screws. Since the internal shape and structure of different electrical housings are different, and most lead frame mounting thread holes are fixed at the four corners of the lead frame, the lead frame is easily affected by the internal structure of the electrical housing, resulting in insufficient installation flexibility and limited installation position. Furthermore, during use, the lead frame is prone to contact with the electrical housing, causing wear and affecting its service life and performance stability.

[0004] Therefore, there is a need for an etched lead frame to solve the problems of existing etched lead frames being easily affected by the internal structure of the electrical housing, resulting in installation limitations, and being prone to wear due to contact with the electrical housing during use. Utility Model Content

[0005] The purpose of this invention is to provide an etched lead frame to solve the problems of existing etched lead frames being easily affected by the internal structure of the electrical housing, resulting in installation limitations, and being prone to wear due to contact with the electrical housing during use.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an etched lead frame, comprising a frame body, transverse slots at both ends of the frame body, and longitudinal slots on both sides of the frame body, wherein a protective mechanism is provided in each of the transverse and longitudinal slots.

[0007] Each set of the protective mechanism includes a slide bar installed inside each transverse and longitudinal groove, a movable block movably installed on the slide bar, two parallel rubber pads installed on the movable block, and several evenly distributed positioning holes opened on the top and bottom surfaces of the slide bar. The movable block is provided with an adjustment component.

[0008] It should be noted in the solution that the adjustment component includes two mounting cavities opened inside the movable block, the same bidirectional screw rotatably installed inside the two mounting cavities, two movable plates movably installed on the bidirectional screw, a positioning rod installed on the movable plate and adapted to the positioning hole, a rotating groove opened on the top surface of the movable block, a rotating block rotatably disposed inside the rotating groove and coaxially connected to the bidirectional screw, and a cross groove opened on the top of the rotating block.

[0009] It is worth noting that each of the four corners of the frame body is provided with an arc-shaped groove, and an arc-shaped guide rod is installed in the arc-shaped groove.

[0010] Furthermore, it should be noted that each of the arc-shaped guide rods is slidably mounted with a mounting plate, and the mounting plate has multiple evenly distributed mounting holes.

[0011] In a preferred embodiment, two movable plates on the same movable block are symmetrically arranged, each movable plate is slidably engaged with a corresponding mounting cavity, and each positioning rod is inserted into a corresponding positioning hole.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The rotating block drives the bidirectional screw to rotate, which in turn drives the moving plate to move the positioning rod. When the positioning rod separates from the positioning hole, the position of the moving block can be adjusted, thereby moving the rubber pad. After the positioning rod is reinserted into the positioning hole, the adjusted moving block is locked. The rubber pad prevents the frame body from directly contacting the inner wall of the electrical housing, thus avoiding wear of the etched lead frame during use.

[0014] 2. By cooperating with the arc-shaped guide rod and the mounting plate, the position of the mounting plate is adjusted according to the internal structure of the electrical housing, so that the frame body can flexibly adapt to the installation space inside the electrical housing when it is fixed, thereby preventing the frame body from being restricted in installation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figures 1-4 As shown, this utility model provides a technical solution, including a frame body 1, horizontal grooves 2 opened at both ends of the frame body 1 and vertical grooves 3 opened on both sides of the frame body 1, and a protective mechanism 4 is provided in each horizontal groove 2 and vertical groove 3.

[0022] Each set of protective mechanisms 4 includes a slide bar 41 installed inside each transverse groove 2 and longitudinal groove 3, a movable block 42 movably installed on the slide bar 41, two parallel rubber pads 43 installed on the movable block 42, and several evenly distributed positioning holes 44 opened on the top and bottom surfaces of the slide bar 41. An adjustment component 45 is provided on the movable block 42.

[0023] Specifically, the sliding engagement of the slider 41 and the moving block 42 allows for adjustment of the position of the moving block 42. Meanwhile, the rubber pad 43 prevents direct contact between the frame body 1 and the inner wall of the electrical housing, thus avoiding wear on the etched lead frame during use.

[0024] Further as Figure 2 and Figure 4 As shown, it is worth noting that the adjustment assembly 45 includes two mounting cavities 451 formed inside the movable block 42, the same bidirectional screw 452 rotatably mounted inside the two mounting cavities 451, two movable plates 453 movably mounted on the bidirectional screw 452, a positioning rod 454 mounted on the movable plate 453 and adapted to the positioning hole 44, a rotating groove 455 formed on the top surface of the movable block 42, a rotating block 456 rotatably disposed inside the rotating groove 455 and coaxially connected to the bidirectional screw 452, and a cross groove 457 formed on the top of the rotating block 456.

[0025] Specifically, when adjusting the position of the movable block 42, the installer uses a tool to rotate the rotating block 456 through the cross groove 457, which drives the bidirectional screw 452 to rotate. Under the action of the thread, the bidirectional screw 452 drives the two movable plates 453 to move away from each other, causing the positioning rod 454 to separate from the positioning hole 44, thereby releasing the lock on the movable block 42. After adjusting the position of the movable block 42, the bidirectional screw 452 is rotated in the opposite direction to allow the positioning rod 454 to be inserted into the positioning hole 44.

[0026] Further as Figure 2 As shown, it is worth noting that each of the four corners of the frame body 1 is provided with an arc-shaped groove 5, and an arc-shaped guide rod 6 is installed in the arc-shaped groove 5.

[0027] Further as Figure 1 and Figure 2 As shown, it is worth noting that each arc-shaped guide rod 6 is slidably mounted with a mounting plate 7, and the mounting plate 7 has multiple evenly distributed mounting holes 8.

[0028] Specifically, when the frame body 1 is installed inside the electrical appliance housing, the position of the mounting plate 7 can be flexibly moved through the sliding cooperation between the mounting plate 7 and the arc-shaped guide rod 6, so that the frame body 1 can flexibly adapt to the installation space inside the electrical appliance housing when it is fixed, thereby preventing the frame body 1 from being restricted in its installation.

[0029] Further as Figure 4 As shown, it is worth noting that the two moving plates 453 on the same moving block 42 are symmetrically arranged, each moving plate 453 is slidably engaged with the corresponding mounting cavity 451, and each positioning rod 454 is inserted into the corresponding positioning hole 44.

[0030] Specifically, the two moving plates 453 on the same moving block 42 are symmetrically arranged, so that each positioning rod 454 can cooperate with the positioning hole 44. Each moving plate 453 is slidably engaged with the corresponding mounting cavity 451, which guides the movement of the moving plate 453. Each positioning rod 454 is inserted into the corresponding positioning hole 44. With the insertion and cooperation of the positioning rod 454 and the positioning hole 44, the position adjustment of the moving block 42 and the position locking of the moving block 42 can be realized.

[0031] In summary: When using this etched lead frame, firstly, based on the installation environment inside the electrical housing, a tool is used to rotate the rotating block 456, driving the bidirectional screw 452 to rotate. Under the action of the screw, the bidirectional screw 452 drives the two moving plates 453 to move away from each other. When the moving plates 453 move, they cause the positioning rod 454 to separate from the positioning hole 44, releasing the lock on the moving block 42. Then, the moving block 42 is moved, thereby changing the position of the rubber pad 43 on the slide bar 41. After the moving block 42 moves the rubber pad 43 to the appropriate position, the rotating block 456 is rotated in the opposite direction, driving the bidirectional screw 452 to rotate, causing the moving plate 453 to move the positioning rod 453 to the appropriate position. The rod 454 is inserted into the corresponding positioning hole 44 to relock the moving block 42. After adjusting each moving block 42 in turn, the frame body 1 is protected by the rubber pad 43. Then, according to the installation position inside the electrical housing, the frame body 1 can be installed into the electrical housing through the mounting hole 8 by using the arc guide rod 6 and the mounting plate 7. This completes the installation of the lead frame, improves the flexibility of the lead frame installation, and prevents the lead frame from wearing during use. It effectively avoids the problem that the etched lead frame is easily affected by the internal structure of the electrical housing, which leads to installation restrictions, and the problem that it is easy to come into contact with the electrical housing and cause wear during use.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
