Description

Technical Field

[0001] This utility model relates to the field of three-terminal voltage regulator installation technology, specifically to an auxiliary connection structure between a three-terminal voltage regulator and a heat sink. Background Technology

[0002] During the operation of a three-terminal voltage regulator, heat is generated when current flows through it due to the resistance in its internal circuitry. If this heat cannot be dissipated effectively and promptly, the temperature of the three-terminal voltage regulator will continue to rise. When the temperature exceeds its normal operating temperature range, the performance of the three-terminal voltage regulator will be affected, and in severe cases, it may even lead to component damage and shorten the lifespan of the electronic equipment.

[0003] To effectively dissipate heat from a three-terminal voltage regulator, a heat sink is typically mounted on its surface. The heat sink is usually made of a metal with good thermal conductivity, such as aluminum or copper. Through the close contact between the heat sink and the three-terminal voltage regulator, the heat generated by the regulator can be quickly conducted and dissipated into the surrounding environment, thus ensuring that the three-terminal voltage regulator operates within its normal temperature range.

[0004] Currently, heat sinks and three-terminal voltage regulators are typically connected using screws. Threaded holes are pre-machined on the heat sink, and corresponding mounting holes are provided on the three-terminal voltage regulator. A screw is passed through the mounting hole of the three-terminal voltage regulator and screwed into the threaded hole on the heat sink, thus achieving a fixed connection between the heat sink and the three-terminal voltage regulator.

[0005] However, the lack of a proper positioning structure between the heatsink and the three-terminal regulator makes it difficult to ensure coaxiality during installation. Furthermore, during actual installation, tightening the screws generates a rotational torque on the three-terminal regulator. This torque can easily cause misalignment between the heatsink and the regulator, resulting in misalignment and affecting subsequent installation of the three-terminal regulator. Utility Model Content

[0006] The purpose of this utility model is to provide an auxiliary connection structure between a three-terminal voltage regulator and a heat sink. By accurately positioning and stably fixing the heat sink and the three-terminal voltage regulator, the heat sink and the three-terminal voltage regulator are made coaxial after connection, which facilitates the subsequent installation of the three-terminal voltage regulator.

[0007] The above-mentioned optimized structure of this utility model is achieved through the following technical solution: a three-terminal voltage regulator and heat sink auxiliary connection structure, including a fixing plate;

[0008] Two first limiting plates are symmetrically disposed on the fixed plate, and a first insertion groove is formed between the two first limiting plates and the fixed plate, and a heat sink is inserted into the first insertion groove.

[0009] Two second limiting plates are symmetrically arranged on the top of the two first limiting plates, and a second insertion slot is provided between the two second limiting plates and the heat sink, and a three-terminal voltage regulator is inserted into the second insertion slot.

[0010] A limiting block is provided on one side of the first insertion slot and is attached to one side of the heat sink.

[0011] In some embodiments, the first insertion slot is transitionally fitted with the heat sink.

[0012] In some embodiments, the second connector slot transitions into the three-terminal voltage regulator.

[0013] In some embodiments, a limiting rod is further included, the limiting rod being disposed in the second insertion slot, and one side of the limiting rod being attached to one side of the three-terminal voltage regulator.

[0014] In some embodiments, a fixing block is further included, with both ends of the fixing block fixed to the second limiting plate, and the fixing block passing through the limiting rod, the limiting rod being screwed into the fixing block.

[0015] In some embodiments, an adjustment block is further included, the adjustment block being fixed to the fixed plate;

[0016] A lead screw passes through the adjusting block on one side and is rotatably connected to the limiting block. The limiting block can slide in the first insertion slot. The lead screw and the adjusting block are screwed together.

[0017] In some embodiments, two sliding grooves are also included, which are disposed on the two first limiting plates close to one end of each other;

[0018] Two sliders are symmetrically arranged at both ends of the limiting block and can slide within the groove.

[0019] In summary, this utility model has the following beneficial effects:

[0020] This auxiliary connection structure between the three-terminal voltage regulator and the heat sink uses a first and a second insertion slot to initially position the heat sink and the three-terminal voltage regulator. This ensures that the heat sink and the three-terminal voltage regulator maintain a relatively stable position after being inserted into the corresponding insertion slots. Even when screwing, the position will not shift due to the rotational torque of the screws, ensuring that the heat sink and the three-terminal voltage regulator remain coaxial and guaranteeing connection quality. This facilitates the subsequent installation of the three-terminal voltage regulator on the circuit board. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0026] refer to Figure 1-3 A three-terminal voltage regulator and heat sink auxiliary connection structure includes a fixed plate 1, a first limiting plate 2, a first insertion slot 3, a second limiting plate 5, a second insertion slot 6, and a limiting block 8. The fixed plate 1 can provide an installation platform for other components. Two first limiting plates 2 are symmetrically arranged on the fixed plate 1, and a first insertion slot 3 is formed between the two first limiting plates 2 and the fixed plate 1. A heat sink 4 is inserted into the first insertion slot 3. The width and depth of the first insertion slot 3 are designed according to the size of the heat sink 4 to ensure that the heat sink 4 can be accurately inserted into it, so that the heat sink 4 is restricted in the horizontal direction after being inserted into the first insertion slot 3, thus initially realizing the positioning of the heat sink 4. Two second limiting plates 5 are symmetrically arranged on top of two first limiting plates 2, and a second insertion slot 6 is provided between the two second limiting plates 5 and the heat sink 4. A three-terminal voltage regulator 7 is inserted into the second insertion slot 6. The size of the second insertion slot 6 is designed according to the size of the three-terminal voltage regulator 7, so that the three-terminal voltage regulator can be accurately inserted into the second insertion slot 6, so that the three-terminal voltage regulator 7 is restricted in the horizontal direction, and the three-terminal voltage regulator 7 can maintain a relatively fixed positional relationship with the heat sink 4, achieving coaxiality. A limiting block 8 is provided on one side of the first insertion slot 3 and fits against one side of the heat sink 4. The limiting block 8 can limit the insertion depth of the heat sink 4 into the first insertion slot 3, preventing the heat sink 4 from being over-inserted or under-inserted, and facilitating the installation of the heat sink 4 and the three-terminal voltage regulator 7.

[0027] In some embodiments, the first insertion slot 3 and the heat sink 4 are in transitional fit, and there is a certain gap between the first insertion slot 3 and the heat sink 4. This ensures that the heat sink 4 can be smoothly inserted into the first insertion slot 3, and also prevents the heat sink 4 from shaking randomly in the first insertion slot 3, thereby improving the stability of the heat sink 4 in the first insertion slot 3.

[0028] In some embodiments, the second connector 6 is transitionally fitted with the three-terminal voltage regulator 7, and there is a certain gap between the second connector 6 and the three-terminal voltage regulator 7. This ensures that the three-terminal voltage regulator 7 can be smoothly inserted into the second connector 6, and also prevents the three-terminal voltage regulator 7 from shaking randomly in the second connector 6, thereby improving the stability of the three-terminal voltage regulator 7 in the second connector 6.

[0029] In some embodiments, a limiting rod 9 is also included. The limiting rod 9 is disposed within the second insertion slot 6, and one side of the limiting rod 9 is attached to one side of the three-terminal voltage regulator 7. The limiting rod 9 can limit the insertion depth of the three-terminal voltage regulator 7 within the second insertion slot 6. It can cooperate with the limiting block 8 to facilitate the alignment of the fixing hole on the three-terminal voltage regulator 7 with the threaded hole on the heat sink 4, thereby facilitating the fixing of the three-terminal voltage regulator 7 and the heat sink 4, and thus improving the installation efficiency of the three-terminal voltage regulator 7 and the heat sink 4.

[0030] In some embodiments, a fixing block 10 is further included. The two ends of the fixing block 10 are respectively fixed to the second limiting plate 5, and the fixing block 10 passes through the limiting rod 9. The limiting rod 9 is screwed into the fixing block 10. By rotating the limiting rod 9, the position of the limiting rod 9 in the second insertion slot 6 can be adjusted, thereby adapting to three-terminal voltage regulators 7 of different sizes and improving the versatility of the connection structure.

[0031] In some embodiments, the system further includes an adjusting block 11 and a lead screw 12. The adjusting block 11 is fixed to the fixing plate 1 and can be welded. The adjusting block 11 provides a support point for the installation of the lead screw 12. One side of the lead screw 12 passes through the adjusting block 11 and is rotatably connected to a limiting block 8. The limiting block 8 can slide within the first insertion slot 3. The lead screw 12 and the adjusting block 11 are screwed together. By rotating the lead screw 12, the limiting block 8 can be driven to move within the first insertion slot 3, thereby achieving precise adjustment of the insertion depth of the heat sink 4 and meeting different installation requirements.

[0032] In some embodiments, the system further includes two slide grooves 13 and two sliders 14. The slide grooves 13 are located at one end of the two first limiting plates 2 close to each other, and the two sliders 14 are symmetrically located at both ends of the limiting block 8 and can slide within the slide grooves 13. The cooperation between the sliders 14 and the slide grooves 13 makes the limiting block 8 move more smoothly, preventing the limiting block 8 from shifting or shaking during movement, and improving the accuracy and stability of the adjustment.

[0033] Based on the above, describe the specific working process of this connection structure.

[0034] The specific working principle is as follows:

[0035] Based on the size of the heat sink 4, the size of the three-terminal voltage regulator 7, and the connection position between them (threaded hole and fixing hole), the position of the limiting rod 9 in the second insertion slot 6 and the position of the limiting block 8 in the first insertion slot 3 are set. By rotating the limiting rod 9, it is placed in the set position. By rotating the screw 12, the limiting block 8 is moved to the set position of the first insertion slot 3.

[0036] Insert the heat sink 4 into the first insertion slot 3, ensuring a tight fit between the heat sink 4 and the limiting block 8, thus positioning the heat sink 4 within the first insertion slot 3. Place the three-terminal voltage regulator 7 on the heat sink 4 and insert it into the second insertion slot 6, ensuring a tight fit between the limiting rod 9 and the three-terminal voltage regulator 7, thus positioning the three-terminal voltage regulator 7 within the second insertion slot 6. This achieves coaxiality between the three-terminal voltage regulator 7 and the heat sink 4. At this point, the threaded hole and the fixing hole are coaxial. Use screws or other fasteners to pass through the fixing hole of the three-terminal voltage regulator 7 and the threaded hole of the heat sink 4, firmly fixing the two together, completing the auxiliary connection between the three-terminal voltage regulator and the heat sink. During this process, there will be no positional shift due to the rotational torque of the screws, ensuring that the heat sink 4 and the three-terminal voltage regulator 7 remain coaxial at all times, guaranteeing connection quality, and facilitating the subsequent installation of the three-terminal voltage regulator 7 on the circuit board.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
