Description

Technical Field

[0001] This disclosure relates to the field of semiconductor technology, and more particularly to a connection component and circuit module. Background Technology

[0002] In the semiconductor manufacturing and packaging field, ensuring the reliability, stability, and ease of connection between components is crucial. As semiconductor technology and product design advance towards high-density integration, high performance, and miniaturization, the requirements for connection components are becoming increasingly stringent. However, in achieving these goals, effectively connecting different semiconductor frames or components in a robust yet easily detachable manner has become a pressing issue. Related technologies utilize methods such as soldering and adhesives to achieve connections between components. While soldering provides a high-strength, permanent bond, its non-removable nature makes maintenance and replacement extremely inconvenient and can potentially cause thermal damage to sensitive semiconductor components. Adhesive bonding, while suitable for connecting dissimilar materials, lacks reversibility, and aging issues limit its long-term reliability. Each connection method in these technologies has its limitations: some are difficult to disassemble, some occupy a large space, and some provide insufficient connection strength. This prevents them from fully meeting the modern semiconductor industry's demands for both robust connections and easy disassembly. Summary of the Invention

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the representation of this disclosure, "a set" means two or more, unless otherwise explicitly specified.

[0028] For the purpose of clarity, devices unrelated to the description are omitted, and the same or similar components throughout the specification are given the same reference numerals.

[0029] Throughout this specification, when it is said that a device is "connected" to another device, this includes not only "direct connection" but also "indirect connection" by placing other components in between. Furthermore, when it is said that a device "comprises" a certain constituent element, unless otherwise stated otherwise, this does not exclude other constituent elements, but rather implies that other constituent elements may be included.

[0030] While the terms first, second, etc., are used in some examples herein to refer to various elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, first interface and second interface, etc., are used.

[0033] In related technologies, methods for connecting electronic components (including but not limited to frames) include soldering. While soldering provides a high-strength, permanent connection, its non-disassembly hinders repair and replacement and can cause thermal damage to sensitive components.

[0034] To address the aforementioned problems, one embodiment of this disclosure provides a connection assembly for connecting electronic components. This assembly overcomes the shortcomings of related technologies by employing a bayonet with a resilient clamping mechanism and a matching clip. When the clip is inserted into the bayonet, the clip head opens the resilient clamping mechanism and passes through the clamping gap, while the neck is held in place by the resetting resilient clamping mechanism, ensuring a strong and reliable connection that remains stable even under vibration. This simplifies assembly and disassembly processes, eliminating the need for complex alignment operations or additional tools, improving work efficiency and facilitating subsequent maintenance and replacement. Furthermore, the compact design optimizes space utilization, making it ideal for highly integrated miniaturized designs and helping to reduce the overall device size. Simultaneously, this connection assembly has high adaptability, capable of meeting the connection needs between electronic components of different sizes and shapes.

[0035] Please refer to this as well. Figures 1-5 Example, wherein, Figure 1 , Figure 3 as well as Figure 4 This embodiment illustrates one application scenario of the connection component 100. In actual use, the connection component 100 can be applied to other application scenarios. To facilitate the demonstration of the application scenarios of the connection component 100, the connection of the IGBT frame is used as an example. The connection component 100 includes: a bayonet 110, an elastic clamping mechanism 130, and a locking element 120.

[0036] A bayonet 110 is provided on the first component, and an elastic clamping mechanism 130 is provided on the hole wall to form a clamping gap.

[0037] A locking element 120 is provided on the second component and is inserted into the bayonet 110: the locking element 120 includes a locking head 121 and a neck 122 that is connected to the locking head 121 with a decreasing diameter; wherein, during the process of the locking element 120 being inserted into the bayonet 110, the locking head 121 is opened by the elastic clamping mechanism 130 and passes through the clamping gap, and is clamped by the elastic clamping mechanism 130 that has reset the neck 122 to form a restriction on the retraction of the locking head 121.

[0038] Specifically, refer to Figure 2In this embodiment, when the card 120 is inserted into the slot 110, the card head 121 first opens the elastic clamping mechanism 130 within the hole wall. Since the diameter of the card head 121 is larger than the neck 122, this process requires overcoming the elastic force of the elastic clamping mechanism 130. As the card head 121 gradually passes through the clamping gap, the elastic clamping mechanism 130 undergoes elastic deformation, temporarily widening the original gap to allow the card head 121 to pass through. Once the card head 121 has completely passed through the clamping gap, the elastic clamping mechanism 130 returns to its original state due to the elastic force generated by compression when it is opened, and tightly clamps the neck 122 portion of the card 120, preventing the card head 121 from retracting due to external forces. Figure 2 In this embodiment, in order to prevent the card 120 and the elastic clamping mechanism 130 from wobbling back and forth, thereby causing positional deviation, a housing is also provided to limit the card 120 and the elastic mechanism in the front and back directions.

[0039] Optionally, refer to Figure 2 as well as Figure 5 In this embodiment, the elastic clamping mechanism 130 includes at least one pair of opposing clamping components that are elastically extendable and retractable.

[0040] Specifically, each clamping assembly may consist of one or more spring plates, which can automatically adjust their shape and position according to changes in external force to provide optimal clamping effect. Simultaneously, the opposing arrangement ensures a more secure clamping, preventing loosening or shifting. When disassembly is required, simply apply sufficient external force to expand the clamping assembly again, and the clip 120 can be easily removed.

[0041] Optionally, in some embodiments, the elastic clamping mechanism 130 may further include a plurality of elastically retractable clamping components that are uniformly arranged around the hole wall in a circumferential direction.

[0042] Specifically, by evenly arranging multiple clamping components around the hole wall, it can be ensured that the clamping force on the card 120 during insertion is evenly distributed in the circumferential direction. This improves the stability and reliability of the clamping. Multiple clamping components provide multi-point support, which not only increases the contact area with the card 120 but also makes the clamping force more balanced, helping to reduce the possibility of the card 120 loosening. In some embodiments, different numbers of clamping components can be selected according to specific application requirements and hole size. Typically, 3 to 6 clamping components can provide a good clamping effect, ensuring sufficient clamping force without making the structure overly complex.

[0043] Optionally, please refer to the following as well. Figure 2 as well as Figure 5 In one embodiment, the clamping assembly includes a clamping member 131 and an elastic member 132.

[0044] The clamping member 131 is directed into the bayonet 110 and is retractably engaged in the telescopic hole formed by the recess in the hole wall;

[0045] The elastic member 132, which is provided in conjunction with the clamping member 131, is used to provide the clamping member 131 with an elastic force for resetting during extension and retraction.

[0046] Specifically, the shape of the clamping member 131 can be adjusted according to actual needs. For example, it can be designed as an arc-shaped sheet structure to better fit the hole wall and adapt to the insertion process of the card 120; anti-slip textures or coatings can also be added to the contact surface to improve friction and stability.

[0047] When the clip 120 is inserted, the clamping member 131 is compressed and moves into the telescopic hole, allowing the clip 120 to pass through. Once the clip 120 has passed the clamping member and a specific part (such as the neck 122) is fully aligned with the clamping member 131, the clamping member 131 is reset by the action of the elastic member 132, clamping the neck 122 portion of the clip 120 and preventing the clip 120 from retracting. The elastic member 132 is configured to cooperate with the clamping member 131 to provide a reset elastic force for the clamping member 131 during telescopic movement. This means that when no external pressure is applied, the elastic member 132 keeps the clamping member 131 in its initial position; when the clip 120 is inserted, causing the clamping member 131 to be compressed and moved backward, the elastic member 132 is compressed; once the corresponding part of the clip 120 has completely passed through or the external force has been removed, the elastic member 132 pushes the clamping member 131 back to its initial position.

[0048] Optionally, please refer to the following as well. Figure 2 as well as Figure 5 In this embodiment, the clamping member 131 includes a first guide portion that contacts the clamping head 121. The first guide portion is provided with a first guide surface that guides the clamping head 121 to pass over. The first guide surface has a shape with a gradually decreasing cross-section in the direction approaching the inner end of the clamping member 131 at the jaw 110.

[0049] Specifically, in some embodiments, the first guide portion and the first guide surface enable the chuck 121 to be inserted more smoothly and reduce resistance and potential damage during insertion. Viewed from the outside of the bayonet 110 inwards, the first guide surface forms a conical, frustum-shaped, or wedge-shaped structure, its width (or diameter) gradually decreasing as it approaches the end of the clamping member 131. When the chuck 121 begins to insert into the bayonet 110 and contacts the first guide surface, due to the special shape of the first guide surface (gradually decreasing cross-section), it effectively distributes the pressure applied by the chuck 121 over a larger area, thereby reducing the pressure per unit area and reducing the risk of possible wear or damage. The chuck 121 first contacts the wider portion and then gradually moves along the slope of the first guide surface to the narrower portion. During this process, the chuck 121 naturally pushes the clamping member 131 outwards, causing the clamping member 131 to move backwards and compress the elastic member 132. In some embodiments, to further reduce friction and improve wear resistance, special surface treatments, such as coatings or polishing, can be applied to the first guide surface to make its surface smoother. The angle of the first guide surface needs to be set according to the actual situation. It should not be too steep, making insertion difficult, nor too gentle, thus losing its effective guiding function. Usually, the optimal angle range needs to be determined through actual testing.

[0050] Optionally, please refer to the following as well. Figure 2 as well as Figure 5 In this embodiment, the clamping member 131 includes a clamping portion 1311 and a connecting portion 1312 connected to the clamping portion, wherein the connecting portion 1312 is connected to the elastic member 132. Optionally, the connecting portion 1312 is shaped to fit the telescopic hole.

[0051] Specifically, in some embodiments, a connecting portion 1312 is provided to limit the movement direction of the clamping member 131 and prevent it from wobbling when moving within the movement space formed by the recess in the hole wall. The design of the connecting portion 1312 matches the shape of the telescopic hole, ensuring that the clamping member 131 moves smoothly in the hole without shifting or getting stuck. In some embodiments, the connecting portion 1312 can effectively distribute stress, reduce local wear and fatigue damage, thereby extending the overall service life of the clamping assembly.

[0052] Optionally, the connecting part 1312 and the clamping part 1311 are integrally formed. Integrating the clamping part 1311, the connecting part 1312 and the elastic element 132 together simplifies the design of the overall structure, reduces the number of parts, and helps to reduce manufacturing costs and maintenance complexity.

[0053] Alternatively, please refer to Figure 5In this embodiment, the two ends of the elastic member 132 are fixedly connected to the bottom surface of the telescopic hole and the connecting part 1312, respectively. Optionally, the telescopic hole is provided with a stop portion on one side of the bayonet 110 to stop the clamping member 131, and the stop portion is provided with a guide opening that allows the clamping part 1311 to pass through and is shaped to fit it.

[0054] Specifically, the connection method of the elastic member 132 ensures that the elastic member 132 is confined within the telescopic hole. The stop portion is used to limit the maximum stroke of the clamping member 131, preventing the clamping member 131 from disengaging from the predetermined path or being damaged due to excessive movement. The guide port is used to allow the clamping member 1311 to pass through and guide its direction of movement.

[0055] Optionally, please refer to the following as well. Figure 2 as well as Figure 5 In this embodiment, the clamping mechanism further includes at least one guide member 133 fixedly disposed in the telescopic hole and extending along the telescopic direction, which is slidably engaged with the clamping member 131 to guide the telescopic direction of the clamping member 131.

[0056] Specifically, the guide member 133 is used to guide the movement of the clamping member 131. In some embodiments, the guide member 133 and the connecting part 1312 are slidably connected (for example, the guide member 133 is shaped to fit and slidably passes through the through hole on the connecting part 1312), thereby guiding the movement direction of the clamping member 131. At the same time, in order to limit the elastic member 132, in some embodiments two guide members 133 are provided to limit the elastic member 132 between the two guide members 133.

[0057] Alternatively, please refer to Figure 5 In this embodiment, the card head 121 includes a second guide surface that contacts the clamping member 131. The second guide surface has a gradually decreasing cross-section shape in the direction near one end of the card head 121 within the slot 110.

[0058] Specifically, in some embodiments, the second guide surface enables the clasp 121 to push the clamp 131 more smoothly during insertion and reduces frictional resistance, ensuring that the clasp 121 can pass smoothly through the clamping assembly.

[0059] When the card 120 begins to be inserted into the bayonet 110, the card head 121 first contacts the first guide portion of the clamping member 131. Due to the design of the second guide surface on the card head 121, the card head 121 can contact the clamping member 131 with a small initial contact area. As the card head 121 continues to advance, the contact area gradually increases. At the same time, due to the inclination angle of the second guide surface, the pressure distribution on the clamping member 131 is more uniform, reducing local stress concentration. As the card head 121 gradually penetrates deeper into the bayonet 110 along the slope of the second guide surface, the clamping member 131 is gradually pushed open and moved backward, compressing the elastic member 132. The entire process is made smoother by the presence of the second guide surface, reducing possible jamming. To remove the card 120, the clamping member 131 must be manually pushed open (overcoming the elastic force of the elastic member 132) to release the clamping on the neck 122 of the card 120, thereby allowing the card 120 to be pulled out of the bayonet 110. During this process, the second guide surface does not participate directly, but its design facilitates operation during the next insertion.

[0060] In another embodiment of this disclosure, a circuit module is provided, comprising a first electronic component and a second electronic component, the first electronic component and the second electronic component being connected via at least one connection component 100 as described in any of the foregoing embodiments. The circuit module may be exemplified as an IGBT, etc.

[0061] The above embodiments are merely illustrative of the principles and effects of this disclosure and are not intended to limit this disclosure. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this disclosure. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this disclosure should still be covered by the protection scope of this disclosure.
