Description

Technical Field

[0001] The utility model belongs to the technical field of generator rectifiers, and in particular relates to a rectifier B+ bolt riveting and anti-loosening structure. The structure is different from the traditional riveting structure and has not been publicly displayed in any field. Background Art

[0002] Generator rectifiers usually have B+ bolts, and the bolts are usually riveted onto the positive plate. The riveting connection between the B+ bolt and the plate is very important. Since the B+ bolt connects the vehicle wiring harness, the harness will shake during use. If it becomes loose, the connection resistance will increase, causing the rectifier diode to burn out. The original riveting structure is a round hole structure. After the rivet enters the round hole, it expands due to the riveting pressure and fits tightly against the round hole of the plate. It is fastened by the friction between the rivet and the inner wall of the round hole. However, after a period of use, the alternating hot and cold cycles and the vibration generated by the harness make the riveting no longer reliable and loosen.

[0003] The technical problems existing in the prior art of the generator rectifier B+ bolt riveting connection mainly include:

[0004] 1) Long-term stability of the connection between rivets and round holes: Although the original round hole structure can achieve a tight connection between the rivet and the plate during the initial installation, the connection stability between the rivet and the round hole will gradually decrease over time due to the alternating hot and cold cycles and the vibration of the wiring harness. This connection method relies on the friction between the rivet and the inner wall of the round hole, which is easily weakened under long-term use and environmental changes.

[0005] 2) Electrical failure caused by loosening: Since the B+ bolt is directly connected to the vehicle wiring harness, its stability is critical to the entire electrical system. When the riveted connection is loose, it will cause the connection resistance to increase, which not only affects the efficiency of the electrical system, but also causes the rectifier diode to overheat or burn out, thus posing a safety risk.

[0006] 3) Impact of environmental factors on connection reliability: Generators are often exposed to harsh working environments such as high temperature and vibration during use, which can have an adverse effect on riveting connections. In particular, temperature changes can cause metal materials to expand or contract, further exacerbating the loosening of the connection.

[0007] 4) Maintenance and repair costs: The unreliability of riveting connections increases the maintenance and repair costs of rectifiers. Once loosening occurs, the rectifier needs to be completely replaced or complicated repairs need to be carried out, which is an additional burden for users.

[0008] Although the riveting connection method in the prior art provides a stable connection in the initial stage, it has the problem of decreased stability and increased risk of failure in long-term use and harsh working environments. Therefore, it is necessary to improve this connection method to improve the long-term stability and reliability of the connection. Utility Model Content

[0009] In view of the problems existing in the prior art, the utility model provides a rectifier B+ bolt riveting and anti-loosening structure.

[0010] The utility model is realized in this way: a rectifier B+ bolt riveting and anti-loosening structure, the structure comprises: B+ bolts, rivet riveting, and positive plates.

[0011] Furthermore, the riveting holes on the positive plate are special-shaped holes with square grooves.

[0012] In combination with the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solutions to be protected by the utility model are as follows:

[0013] First, the riveting holes on the generator plate are changed from round holes to special-shaped holes with grooves. When the rivets are riveted, the metal material is squeezed into the square groove and receives forces from different directions in the square groove, which prevents the rivets from loosening and rotating. Therefore, the rivet riveting method does not loosen, and the rectifier B+ bolts are prevented from loosening and causing adverse failures.

[0014] The utility model achieves the effect of preventing the rectifier B+ bolts from loosening after riveting through structural innovation, thus avoiding the occurrence of malfunctions after loosening.

[0015] The technical solution of the utility model solves the technical problem that people have been eager to solve but have never been able to solve successfully: the solution can effectively solve the current problem of riveting looseness and completely solve this failure mode, thereby increasing the service life of the product.

[0016] Second, the significant technical progress of the rectifier B+ bolt riveting anti-loosening structure is reflected in the following aspects:

[0017] 1) Enhanced connection stability: By adopting the rivet pressing method, the connection between the B+ bolt and the positive plate is more stable, greatly reducing the risk of loosening due to vibration or long-term use. This is particularly important for electrical equipment in high-vibration environments, such as in automobiles or industrial machinery.

[0018] 2) Improved reliability: Under high load and high temperature conditions, traditional bolt connections will gradually loosen, affecting the performance of the rectifier. The rivet-pressed structure greatly improves the reliability of the connection and ensures the stability of the rectifier under various working conditions.

[0019] 3) Optimized design: The square grooved special-shaped holes on the positive plate provide a more stable mounting point for the rivet, preventing the rivet from rotating or shifting when stressed, thereby improving the anti-loosening ability of the entire connection. This design optimization not only increases the strength of the structure, but also improves assembly efficiency.

[0020] 4) Extend equipment life: Since maintenance and repairs caused by loose connections are reduced, this structure can effectively extend the service life of the rectifier and related electrical equipment and reduce long-term operating costs.

[0021] 5) Wide applicability: This anti-loosening structure design is not only suitable for rectifiers, but can also be widely used in other equipment that requires reliable electrical connections, especially in applications that are sensitive to vibration or require long-term reliable connections.

[0022] The design of the rectifier B+ bolt riveting anti-loosening structure provided by the utility model has achieved remarkable technical progress in improving connection stability, reliability, equipment life and design optimization. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0028] The following are two specific embodiments and implementation schemes for the rectifier B+ bolt riveting anti-loosening structure:

[0029] Example 1: Application of automobile generator rectifier

[0030] 1) Component preparation: Prepare rectifier B+ bolts, positive plates with special-shaped holes and square grooves, and rivets.

[0031] 2) Riveting: A special-shaped riveting hole with a square groove is preset on the positive plate. The rivet is installed in this hole and riveted with a special tool to ensure that the rivet is firmly fixed.

[0032] 3) Bolt installation: Install the B+ bolt to the positive plate and connect it to the positive plate through a rivet-pressed structure.

[0033] 4) Rectifier assembly: Assemble the rectifier into the car generator, ensuring the correct connection of the B+ bolt with the rest of the generator.

[0041] These two embodiments demonstrate the practicality and effectiveness of the rectifier B+ bolt riveting anti-loosening structure in different application environments, especially in situations requiring vibration resistance and high reliability.

[0042] like Figure 1 As shown, the utility model provides a rectifier B+ bolt riveting and anti-loosening structure, which includes: a B+ bolt 1, a rivet riveting 2, and a positive plate 3.

[0043] like Figure 2 The figure shows a schematic diagram of a conventional circular hole.

[0044] like Figure 3 As shown, the riveting hole on the positive plate is a special-shaped hole with a square groove 4.

[0045] The connection relationship and working principle of the rectifier B+ bolt riveting anti-loosening structure are as follows:

[0046] B+ bolt: This is a critical part of the entire structure and is used to transfer the current from the rectifier to the positive plate. The B+ bolt is fixed to the positive plate by its threaded portion.

[0047] Rivet pressing: Rivets are used to strengthen the connection between the B+ bolt and the positive plate to prevent the bolt from loosening due to vibration or long-term use. The rivet is fixed to the positive plate by riveting and cooperates with the B+ bolt.

[0048] Positive plate: This is the main component of the rectifier and is used to connect the positive pole of the electrical system. The positive plate is provided with riveting holes for installing rivets and B+ bolts.

[0049] Special-shaped hole with square groove: A specially shaped hole preset on the positive plate for riveting rivets. The square groove is designed to better fix the rivet and prevent it from turning or loosening during use.

[0050] Working principle: When the B+ bolt is installed and tightened to the positive plate, it effectively transfers current from the rectifier to the rest of the electrical system. The rivet is riveted onto the positive plate to ensure the stability of the bolt. The presence of the rivet significantly improves the mechanical stability of the connection and reduces the risk of bolt loosening due to vibration or thermal expansion. Especially in automobiles or other power equipment, this design is essential to ensure the reliability of electrical connections. The square groove-shaped hole on the positive plate provides a more stable mounting point for the rivet. The square groove design prevents the rivet from rotating or shifting when subjected to external force, thereby improving the anti-loosening ability of the entire connection. With this design, the rectifier B+ bolt riveting anti-loosening structure can provide stable and reliable current transmission in various working environments, and is particularly suitable for those application scenarios that require high mechanical stability and electrical reliability. After the implementation of this solution, faulty parts caused by riveting problems have been eliminated, and the product life has been improved.
