Description

Technical Field

[0001] This utility model relates to the field of fixing electronic components, and in particular to a straight plate-shaped pressure block assembly. Background Technology

[0002] Existing MOSFETs or IGBT chips are all mounted and fixed using a combination of pressure caps, such as Figure 1 As shown, the combined cover includes an insulating upper cover, an insulating lower cover, an intermediate spring, and a spring limit frame. In actual use, the intermediate spring between the insulating upper cover and the insulating lower cover is bent. In actual use, the intermediate spring is easy to deform and difficult to restore its bent shape. At the same time, the two ends of the intermediate spring are easy to insulate the upper surface of the insulating lower cover during operation, which will damage the insulating lower cover. As a result, the combined cover cannot press the electronic components tightly during the process of fixing the electronic components, resulting in unstable fixing of the electronic components.

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] See Figures 2-6 This utility model provides a technical solution:

[0026] A straight-plate pressure block assembly includes an insulating upper cover 1, an insulating lower cover 2, an intermediate spring piece 3, a spring piece limiting frame 4, a quick-connect assembly, and a limiting assembly. The insulating upper cover 1 is disposed on and mates with the insulating lower cover 2. Both ends of the insulating upper cover 1 and both ends of the insulating lower cover 2 are connected by quick-connect assemblies. A limiting assembly is provided between the insulating upper cover 1 and the insulating lower cover 2. The spring piece limiting frame 4 is fixedly disposed on the middle part of the insulating lower cover 2. The straight-plate-shaped intermediate spring piece 3 is disposed within the spring piece limiting frame 4, and the upper surface of the intermediate spring piece 3 mates with the lower surface of the insulating upper cover 1, while the lower surface of the intermediate spring piece 3 mates with the upper surface of the insulating lower cover 2. The insulating lower cover 2 is provided with a mounting groove 25 for fixing components 24. The mounting groove 25 is used to position the components 24. The insulating upper cover 1, insulating lower cover 2, spring-loaded limiting frame 4, limiting assembly, and quick-connect assembly are all made of insulating material, generally plastic. The intermediate spring-loaded piece 3 is a straight plate made of metal. Its function is to reduce the deformation of the insulating upper cover 1 and insulating lower cover 2 during operation. The spring-loaded limiting frame 4 is a square frame, and the projection of the intermediate spring-loaded piece 3 onto the insulating lower cover 2 is also square. The function of the spring-loaded limiting frame 4 is to prevent the intermediate spring-loaded piece 3 from being misaligned between the insulating upper cover 1 and insulating lower cover 2, thus preventing it from failing to secure the electronic components. The quick-connect assembly secures the insulating upper cover 1 and insulating lower cover 2 together and also facilitates their disassembly.

[0027] In some embodiments, the limiting assembly includes length limiting components and width limiting components. Length limiting components are symmetrically arranged between the two ends of the insulating upper cover 1 and the two ends of the insulating lower cover 2, and width limiting components are arranged between the two sides of the insulating upper cover 1 and the two sides of the insulating lower cover 2. The two sets of length limiting components further restrict the relative sliding between the insulating upper cover 1 and the insulating lower cover 2, preventing the quick-connect assembly connecting the two ends from breaking. The length limiting components and width limiting components work together to make the connection between the insulating upper cover 1 and the insulating lower cover 2 more secure.

[0028] In some embodiments, the length limiting component includes an upper anti-slip protrusion 5 and a lower anti-slip protrusion 6. The upper anti-slip protrusion 5 is fixedly disposed on the insulating upper cover 1, and the lower anti-slip protrusion 6 is fixedly disposed on the insulating lower cover 2. The lower anti-slip protrusion 6 is disposed between the end of the quick-connect assembly and the end of the spring-loaded limiting frame 4, and the upper anti-slip protrusion 5 is disposed between the end of the spring-loaded limiting frame 4 and the lower anti-slip protrusion 6. The spring-loaded limiting frame 4, the upper anti-slip protrusion 5, and the lower anti-slip protrusion 6 work together to prevent misalignment of the insulating upper cover 1 and the insulating lower cover 2 during operation.

[0029] In some embodiments, the width limiting component includes a lower limiting step 7, an upper limiting step 8, an outer limiting protrusion 9, an inner limiting protrusion 10, and a limiting platform 11. The lower limiting step 7 is provided on one side of the insulating lower cover 2, and the upper limiting step 8, which cooperates with the lower limiting step 7, is provided on one side of the insulating upper cover 1. The outer limiting protrusion 9 and the inner limiting protrusion 10 are provided on the other side of the insulating lower cover 2. The two ends of the inner limiting protrusion 10 are fixedly connected to the lower anti-slip protrusion 6, respectively. The limiting platform 11 is provided on the other side of the insulating upper cover 1, and is positioned between the outer limiting protrusion 9 and the inner limiting protrusion 10. The lower limiting step 7 cooperates with the upper limiting step 8, and the outer limiting protrusion 9 and the inner limiting protrusion 10 cooperate with the limiting platform 11, jointly restricting the sliding of the insulating upper cover 1 and the insulating lower cover 2 to both sides, making the fit between the insulating upper cover 1 and the insulating lower cover 2 more stable and ensuring the stability of the electronic components during fixation. To prevent the upper anti-slip protrusion 5 and the lower anti-slip protrusion 6 from being broken, the two ends of the limiting inner protrusion 10 are fixedly connected to the two lower anti-slip protrusions 6 respectively, one end of the upper anti-slip protrusion 5 is fixedly connected to the limiting platform 11, and the other end of the upper anti-slip protrusion 5 is fixedly connected to the limiting upper step 8.

[0030] In some embodiments, the intermediate spring piece 3 is provided with anti-slip holes 12, and an anti-slip rod 13 is provided in the anti-slip holes 12. The anti-slip rod 13 is fixedly mounted on the insulating upper cover 1 or the insulating lower cover 2. The anti-slip rod 13 is fixed on the insulating lower cover 2 and cooperates with the anti-slip holes 12 on the intermediate spring piece 3. This effectively prevents the intermediate spring piece 3 from rotating within the spring piece limiting frame 4 and also prevents the intermediate spring piece 3 from sliding a large distance within the spring piece limiting frame 4.

[0031] In some embodiments, the quick-connect assembly includes an upper connecting buckle 15 and a lower connecting buckle 16. The upper connecting buckle 15 is fixedly disposed on the end of the insulating upper cover 1, and the lower connecting buckle 16, which cooperates with the upper connecting buckle 15, is fixedly disposed on the end of the insulating lower cover 2. Both the upper connecting buckle 15 and the lower connecting buckle 16 are made of insulating plastic. When the upper connecting buckle 15 and the lower connecting buckle 16 are fastened together, they serve as a connector. When the upper connecting buckle 15 and the lower connecting buckle 16 are separated, the insulating upper cover 1 and the insulating lower cover 2 can be separated.

[0032] In some embodiments, an upper mounting hole 17 is provided on the middle portion of the insulating upper cover 1, a lower mounting hole 18 is provided on the insulating lower cover 2 to mate with the upper mounting hole 17, and a middle mounting hole 19 is provided on the middle portion of the intermediate spring piece 3 to mate with the lower mounting hole 18. The upper mounting hole 17, the middle mounting hole 19, and the lower mounting hole 18 are used together to install screws, thereby fixing the technology to the required equipment.

[0033] In some embodiments, an insulating top cover 1 is fixedly provided with a mounting ring 21 that mates with an upper mounting hole 17. An anti-rotation protrusion 22 is fixedly provided on the outer wall of the mounting ring 21, and an anti-detachment protrusion 23 that does not contact the outer wall of the mounting ring 21 is fixedly provided on the upper end of the anti-rotation protrusion 22. The side of the anti-rotation protrusion 22 is fixedly connected to the outer wall of the mounting ring 21, one end of the anti-rotation protrusion 22 is fixed to the insulating top cover 1, and the anti-detachment protrusion 23 is fixed to the other end of the anti-rotation protrusion 22. Other components can be installed on the insulating top cover 1 through the cooperative use of the mounting ring 21, the anti-rotation protrusion 22, and the anti-detachment protrusion 23.
