[0029] The preferred embodiments of the present disclosure are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure. In addition, the embodiments and features in the embodiments of the present disclosure may be combined with each other if no conflict occurs.

[0030] This embodiment provides a fuse box for connecting the positive pole of the battery and the positive terminal of the wiring harness, such as Figures 1 to 7As shown, it includes a box body, a fuse 4 and a conductive bar 5. The box body includes a box body 1 and at least two fixing members 2. The fixing member 2 includes a positioning portion 201 at the bottom and a stud 202 protruding from the plane of the positioning portion 201. The box body 1 is provided with a mounting groove 101. The side walls opposite to the mounting groove 101 are provided with protruding limiting ribs 102. The positioning portion 201 can slide in the slide formed by the bottom surface of the mounting groove 101 and the limiting ribs 102. At least one clamping structure 3 is provided on the bottom surface of the mounting groove 101, which can limit the positioning portion 201 in the slide. One end of the conductive bar 5 is conductively connected to the positive pole, one end of the fuse 4 is conductively connected to the other end of the conductive bar 5 through one of the fixing members 2, and the other end of the fuse 4 is conductively connected to the positive terminal through another fixing member 2. The fixing member 2 is clamped and fixed with different clamping structures 3 in the slide, and fuses 4 of different lengths are installed accordingly.

[0031] In this embodiment, the box body 1 is made of high-strength plastic material with sufficient heat resistance and insulation. The mounting groove 101 is arranged along the extension direction of the box body 1, and two fixing members 2 are arranged. The two fixing members 2 are arranged in the mounting groove 101 and can slide along the extension direction of the mounting groove 101. Two limiting ribs 102 are arranged along the extension direction of the mounting groove 101 and are located in the same plane. The limiting ribs 102 and the bottom surface of the mounting groove 101 have a certain space to form a slideway. The positioning part 201 is arranged in a rectangular shape, and the two opposite sides of the positioning part 201 are located in the slideway and can slide along the slideway. The axial distance between the two fixing members 2 is adjusted to adapt to fuses 4 of different lengths. The bottom surface of the limiting rib 102 abuts against the top surface of the positioning part 201, so that the positioning part 201 remains stable in the mounting groove 101, and is not easy to shake or displace, ensuring that the fixing member 2 maintains a correct posture during use. There are multiple clip structures 3 arranged at intervals along the extension side of the installation groove 101, and the positioning part 201 is clipped and cooperated with the clip structure 3 to fix the fixing member 2 in the installation groove 101. This can ensure that the positioning part 201 is accurately positioned in the slide, thereby improving the accuracy of installation and the overall stability of the structure.

[0032] In actual use, first insert the positioning portion 201 of one of the fixing members 2 into the slideway and fix it by snapping with the snap-fit ​​structure 3 in the mounting groove 101, then connect one end of the conductive bar 5 to the fixing member 2, put one end of the fuse 4 on the stud 202 and connect it to the conductive bar 5, and then connect the other end of the conductive bar 5 to the positive pole. According to the length of the fuse 4, adjust the position of the positioning portion 201 on the other fixing member 2 in the slideway in the mounting groove 101, snap-fit ​​it with the snap-fit ​​structure 3 at the corresponding position, then put the other end of the fuse 4 on the stud 202 of the fixing member 2 and connect it to the positive pole to form a passage.

[0033] Through the above technical solution, the fixing member 2 is slidably arranged in the installation groove 101 on the box body 1, and the fixing member 2 is limited and fixed in the installation groove 101 by different clamping structures 3 and the positioning part 201, so that fuses 4 of different lengths can be installed accordingly, thereby solving the problem of needing to replace the entire fuse box after the configuration of the car is changed, which increases costs and reduces economic benefits.

[0034] Furthermore, the front end of the limiting rib 102 is a wedge-shaped structure, which facilitates the insertion of the positioning portion 201 and improves work efficiency.

[0035] In some embodiments, reference Figure 2 , Figure 3 and Figure 6 , a plurality of through holes 103 are arranged on the bottom surface of the installation groove 101, and the clamping structure 3 is a spring piece 301 arranged in the through hole 103, one end of the spring piece 301 is fixedly connected to the inner wall of the through hole 103, and the other end extends along the extension direction of the installation groove 101, and a clamping protrusion 302 facing the inside of the installation groove 101 is arranged on the free end of the spring piece 301. The fixed connection between the spring piece 301 and the inner wall of the through hole 103 ensures the stability and reliability of the clamping structure 3. When subjected to external force or vibration, the spring piece 301 can maintain its shape and position, thereby ensuring the position accuracy of the positioning part 201 in the slideway. Moreover, the clamping mode of the spring piece 301 makes the installation and disassembly process convenient and fast, and improves the work efficiency. In addition, the elastic design of the spring piece 301 can also reduce the risk of damage caused by improper operation to a certain extent. The design of the clamping protrusion 302 facing the inside of the installation groove 101 can prevent the positioning part 201 from sliding out of the slideway in an unexpected situation, thereby improving the safety of the device as a whole.

[0036] In order to improve the flexibility of the clamping structure 3, refer to Figure 1 and Figure 2 In some embodiments, the extension direction of at least one spring piece 301 is different from the extension direction of other spring pieces 301. The different extension directions of spring pieces 301 form a plurality of card points at different positions in the installation slot 101. This flexibility enables the fuse box to adapt to the installation requirements of fuses 4 of different lengths, thereby meeting the requirements of different circuit protection. At the same time, its compatibility, space utilization, installation convenience and reliability are also improved.

[0037] In some embodiments, the distance between two adjacent clamping protrusions 302 is greater than or equal to the length of the positioning portion 201 along the extension direction of the mounting groove 101. With such a design, the positioning portion 201 can be stably clamped between two adjacent clamping protrusions 302, avoiding the situation where the clamping is not firm or cannot be clamped due to the distance being too close. It is ensured that the fixing member 2 and the fuse 4 can maintain a stable connection state during the use of the fuse box. When the distance between two adjacent clamping protrusions 302 is large enough, the installation and removal of the positioning portion 201 also becomes simpler and more convenient, which improves the work efficiency and reduces the difficulty of operation.

[0038] In some embodiments, reference Figure 3 and Figure 7 , guide slopes 303 are respectively provided on both sides of the end of the clamping protrusion 302 along the extension direction of the installation groove 101. The provision of the guide slope 303 can play a guiding role when installing the positioning part 201, so that the positioning part 201 can slide more smoothly between two adjacent clamping protrusions 302. The installation difficulty is reduced and the installation efficiency is improved. The guide slope 303 can also gradually increase the contact surface of the positioning part 201 with the clamping protrusion 302 during the sliding process, thereby reducing the friction force during the initial contact, making the positioning part 201 easier to be pushed into the slide. In addition, for the user, the guide slope 303 makes the installation process smoother and easier, and optimizes the use experience. At the same time, this design also reduces the risk of damage caused by improper installation, and further extends the service life of the fuse box.

[0039] In some embodiments, the height of the clamping protrusion 302 protruding from the bottom surface of the mounting groove 101 is greater than or equal to the gap between the positioning part 201 in the slideway in the direction perpendicular to the extension of the mounting groove 101. The height of the clamping protrusion 302 is large enough to ensure that the position of the positioning part 201 in the slideway is stably fixed. This prevents the positioning part 201 from shaking or moving during installation or use, ensures that the positioning part 201 is stably fixed in the mounting groove 101 and prevents accidental falling off, and ensures the stability and safety of the circuit connection.

[0040] In some embodiments, reference Figure 1 , Figure 4 and Figure 7, a contact platform 203 is also included between the positioning portion 201 and the stud 202. One side of the contact platform 203 is connected to the positioning portion 201, and the stud 202 protrudes and extends from the other side of the contact platform 203. The contact platform 203 is located between two opposite limiting ribs 102, and the other side of the contact platform 203 is equal to or higher than the upper plane of the limiting rib 102. The contact platform 203 is arranged between the two limiting ribs 102, which limits the movement range of the stud 202 in the vertical direction, thereby ensuring the verticality of the stud 202 and the accuracy of installation. When the other side of the contact platform 203 is equal to or higher than the upper plane of the limiting rib 102, it can effectively prevent the stud 202 from falling off due to vibration or other external forces during use, further improving the reliability of the device. At the same time, it can also make the installation and disassembly process of the stud 202 smoother and improve work efficiency.

[0041] In some embodiments, reference Figure 5 and Figure 7 The conductive bar 5 includes a horizontal portion 501 and a bent portion 502 connected to the horizontal portion 501. At least part of the horizontal portion 501 is arranged on the box body and is conductively connected to the fuse 4 through the stud 202; the bent portion 502 extends out of the box body and is connected to the positive pole. The horizontal portion 501 enables the conductive bar 5 to be stably fixed on the box body, which is convenient for connection with other components. The bent portion 502 enables the conductive bar 5 to flexibly adapt to different installation positions and angles, ensuring a stable connection with the positive pole. Such a design further improves the stability and flexibility of the device connection, while maintaining the compactness of the internal space of the box body.

[0042] To meet the protection requirements of different circuits, in some embodiments, reference is made to Figure 1 and Figure 5 The box body 1 is provided with a plurality of parallel mounting grooves 101, the number of horizontal portions 501 is multiple and arranged in the plurality of mounting grooves 101, and the fuses 4 are arranged in a plurality of mounting grooves 101 in a one-to-one correspondence. Each mounting groove 101 is provided with a horizontal portion 501 and a corresponding fuse 4, forming a plurality of independent fuse units. This design enables the fuse box to simultaneously install multiple types of fuses 4, protecting multiple circuits, and improving its flexibility and extensiveness of use.

[0043] In order to keep the inside of the box body 1 clean and prevent dust and other impurities from entering and damaging the parts in the box body, and extend its service life, in some embodiments, the fuse box may also include a cover (not shown in the figure), which is arranged above the box body 1 and snapped with the box body 1 to close the box body. The cover is snapped with the box body 1 to form a closed space to prevent safety hazards caused by external factors such as accidental touch and short circuit. In addition, if a fault occurs inside the fuse box, the closed design can prevent the fault from spreading and reduce the risk of injury to other equipment and personnel. The safety and reliability of the inside of the box body are ensured, and the reliability of the device is further improved.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present disclosure.

[0045] Obviously, those skilled in the art can make various changes and modifications to the embodiments of the present disclosure without departing from the spirit and scope of the embodiments of the present disclosure. Thus, if these modifications and variations of the embodiments of the present disclosure fall within the scope of the claims of the present disclosure and their equivalents, the present disclosure is also intended to include these modifications and variations.
