Description

Technical Field

[0001] The present invention relates to the technical field of fuse boxes, and in particular to a method for assembling electrical components of a fuse box and a pressing device. Background Art

[0002] Multiple electrical components need to be installed in a fuse box. Currently, manual installation is the most common method for assembling these components. Operators insert the components one by one into their corresponding mounting locations within the fuse box. This manual installation method relies on operator proficiency and concentration, requiring precise control of the insertion angle and force to achieve a preliminary connection between the components and the fuse box.

[0003] However, installing multiple electrical components requires repetitive plugging and unplugging actions over a long period of time, which can easily lead to fatigue and reduced concentration and precision. This often results in components not being properly plugged in, meaning the connection between the components and the fuse box becomes loose. This compromises the quality of component installation and overall work efficiency. Summary of the Invention

[0043] Multiple electrical components 10 need to be installed in the fuse box 60. Because installing multiple electrical components 10 requires repetitive plugging and unplugging movements over a long period of time, operators can easily become physically fatigued, and their concentration and precision can also decrease. In such situations, the electrical components 10 frequently become loosely connected to the fuse box 60, making it difficult to ensure the quality of the electrical components 10 installed in the fuse box 60 and overall work efficiency.

[0044] Example 1:

[0045] In this embodiment, in order to solve the above problems, this embodiment provides a method for assembling the electrical components 10 of the fuse box 60, as shown in FIG. Figure 1 As shown, the method for assembling the electrical component 10 of the fuse box 60 includes steps S10 to S70. Steps S10 to S70 are described in detail below:

[0046] In step S10, multiple electrical components 10 are pre-connected to the fuse box 60 with a first pressure, so that the electrical components 10 and the fuse box 60 are initially positioned, thereby laying the foundation for subsequent operations. It should be understood that under the action of the first pressure, the electrical components 10 are generally not directly pressed to the bottom.

[0047] Step S20 , obtaining the distribution areas of the plurality of electrical components 10 after pre-plugging, clarifying the distribution of the electrical components 10 on the fuse box 60 , and facilitating subsequent reasonable division and processing of the distribution areas.

[0048] Step S30, the distribution area is divided into a number of first pressure areas and a number of second pressure areas. By dividing the area in this way, the distribution of the electrical components 10 can be accurately classified, providing a basis for adopting different pressing strategies for different areas in the future, making the entire press-fitting process more targeted and reasonable. The first pressure area includes a set of positions of multiple electrical components 10 arranged in a matrix along the first direction and the second direction. The first direction is perpendicular to the second direction, and the first direction is Figure 3 The left and right directions shown, the second direction is Figure 3 The second pressure zone includes a collection of electrical components 10 arranged in either the first or second direction. The first and second pressure zones are spaced apart. It should be understood that while the total number of electrical components 10 in the first and second pressure zones remains the same, the electrical components 10 in the first pressure zone are arranged in two directions for greater concentration, while the electrical components 10 in the second pressure zone are arranged in one direction for greater dispersion.

[0049] Step S40 is completed based on the distribution area division and the pressing device is installed. By the pressing device, it is possible to ensure the effective conduction and distribution of force in the subsequent press-fitting process. The pressing device comprises a pressure rod 20, a plurality of first force transmission rods 30, a plurality of second force transmission rods 40 and a plurality of profile plates 50. The top ends of the plurality of first force transmission rods 30 and the plurality of second force transmission rods 40 are connected to the bottom end of the pressure rod 20, and the spacing between the top end of the first force transmission rod 30 and the bottom end of the pressure rod 20 is equal to the spacing between the top end of the second force transmission rod 40 and the bottom end of the pressure rod 20. The top end of the pressure rod 20 is provided with a driver, which drives the pressure rod 20 to move horizontally and lift, thereby driving the movement of the first force transmission rod 30 and the second force transmission rod 40. The driver can be a conventional mechanical drive source such as a cylinder or a screw. The profiling plate 50 is connected to the bottom end of the first force transmission rod 30 or the bottom end of the second force transmission rod 40. Part of the profiling plate 50's shape corresponds to the shape of the first pressure zone, while part corresponds to the shape of the second pressure zone. This allows downward pressure on the electrical components 10 in different zones. The profiling plate 50 also increases the contact area with the upper surface of the electrical components 10, ensuring more uniform force distribution during assembly. Because the electrical components 10 are arranged in a matrix within the first pressure zone, the profiling plate 50 receives a relatively uniform force distribution along the first and second directions. Therefore, each first pressure zone corresponds to at least one first force transmission rod 30. The second pressure zones are distributed along either the first or second direction, resulting in the electrical components 10 within the second pressure zone taking on an elongated shape. Therefore, each second pressure zone corresponds to multiple second force transmission rods 40, ensuring a relatively uniform force distribution across the profiling plate 50 in the second pressure zone. In this way, according to the distribution areas of different shapes, a corresponding number of first force transmission rods 30 and second force transmission rods 40 are set, which not only makes the electrical component 10 evenly stressed, but also reduces the number of first force transmission rods 30 and second force transmission rods 40 as much as possible, thereby reducing costs.

[0050] Step S50: confirming the geometric center of the distribution area to provide a reference point for the initial position of the pressing device.

[0051] In step S60, the pressing device is driven to its initial position, so that the pressing rod 20 is located above the geometric center, the bottom end of the first force transmission rod 30 points to the corresponding first pressure area, and the bottom end of the second force transmission rod 40 points to the corresponding second pressure area. This ensures that the force applied by the profiling plate 50 during downward pressure is accurately applied to each area of ​​the electrical component 10, ensuring the accuracy and effectiveness of press-fitting.

[0052] Step S70, based on the clamping device being in the initial position, drives the pressure rod 20 to move downward until the downward pressure of the pressure rod 20 reaches the second pressure, and the press-fitting is completed. The downward pressure evenly distributed by the second pressure on each of the electrical components 10 is greater than the first pressure. Compared with pre-plugging and plugging to the bottom of the electrical component 10, the latter requires greater pressure, so the downward pressure evenly distributed by the second pressure to each electrical component 10 is set to be greater than the first pressure, ensuring that multiple electrical components 10 can be accurately pressed into place when they are synchronously pressed to the bottom. Since the downward force point is located at the geometric center of the distribution area, each electrical component 10 is evenly stressed, avoiding the situation of loose insertion and ensuring product quality.

[0053] Furthermore, when the number of electrical components 10 in the first and second pressure zones is the same, since the first pressure zone includes multiple electrical components 10 arranged in a matrix along the first and second directions, the distribution is relatively concentrated. Therefore, the number of first dowel rods 30 should be reduced to simplify the structure. However, due to the higher required pressure, the strength of the first dowel rods 30 needs to be increased. Therefore, each first pressure zone corresponds to a first dowel rod 30, and the diameter of the first dowel rod 30 is larger than the diameter of the second dowel rod 40. The larger diameter of the first dowel rod 30 can withstand greater pressure and reduce deformation, ensuring stable and reliable force transmission. The contour plate 50 corresponding to the second pressure zone is elongated, so multiple second dowel rods 40 are required to ensure uniform force distribution across the electrical components 10 in the second pressure zone. The stress distribution across these multiple second dowel rods 40 is relatively dispersed, so the diameter of the first dowel rod 30 is larger than the diameter of the second dowel rod 40. This structural arrangement ensures that the electrical components 10 in both the first and second pressure zones receive sufficient and stable pressure, achieving uniform force distribution and ensuring product quality.

[0054] In other embodiments, each first pressure region corresponds to multiple first force transmission rods 30, ensuring that multiple points apply pressure to the electrical component 10 within the first pressure region and ensuring uniform pressure distribution. The distance between the bottom ends of two adjacent first force transmission rods 30 in each first pressure region is a first distance.

[0055] The distance between the bottom ends of two adjacent second force transmission rods 40 in each second pressure zone is the second distance. The first distance is smaller than the second distance. Since the electrical components 10 in the first pressure zone are arranged in a matrix and are relatively large and dense, the smaller first distance allows the multiple first force transmission rods 30 to fit more tightly, providing more uniform and sufficient pressure to the electrical components 10; while the electrical components 10 in the second pressure zone are arranged in a single direction, the larger second distance is sufficient to ensure effective pressure transmission. By setting different distances in this way, the electrical components 10 in the first and second pressure zones can both obtain appropriate and uniform pressure, thereby ensuring the press-fit quality of the electrical components 10.

[0056] Furthermore, since the first spacing is smaller than the second spacing, the electrical components 10 in the first pressure region are relatively concentrated. When multiple first force transmission rods 30 are provided, the diameter of the first force transmission rods 30 can be made smaller than the diameter of the second force transmission rods 40, thereby allowing the first force transmission rods 30 to be more flexibly arranged within the limited space of the profiling plate 50, thereby ensuring uniform force on the electrical components 10 in the first pressure region and ensuring the press-fit quality of the electrical components 10. Since the electrical components 10 in the second pressure region are more dispersed, and the number of electrical components 10 corresponding to each force transmission rod is equal, in order to make the downward pressure applied to each dispersed electrical component 10 as uniform as possible, the diameter of the second force transmission rod 40 needs to be set larger, so that the diameter of the second force transmission rod 40 is larger than the diameter of the first force transmission rod 30. Preferably, the cross-section of the second force transmission rod 40 can be set to be elliptical, with the major axis of the ellipse parallel to the distribution direction of the electrical components 10 in the second pressure region.

[0057] In other embodiments, the method for assembling the fuse box 60 and the electrical component 10 further includes steps S80 and S90. Steps S80 and S90 are described in detail below:

[0058] The electrical components 10 include a first type 11 and a second type 12. Step S10 is performed simultaneously on the electrical components 10 of the first type 11 and the second type 12, so that all the electrical components 10 in the fuse box 60 are pre-connected according to the preset distribution positions. This improves the assembly efficiency of the fuse box 60.

[0059] In step S80 , based on the electrical component 10 of the first type 11 , steps S20 to S70 are executed until the electrical component 10 of the first type 11 is press-assembled.

[0060] In step S90, after the press-fitting of the first type 11 electrical components 10 is completed, steps S20 to S70 are executed based on the second type 12 electrical components 10 until the press-fitting of the second type 12 electrical components 10 is completed; after the press-fitting of the first type 11 components is completed, corresponding operations are performed on the second type 12 components, so that the assembly process of the two types of components can be carried out in an orderly manner, mutual interference can be avoided, and assembly efficiency can be improved.

[0061] Among them, when the first type 11 and the second type 12 electrical components 10 are press-fitted, the upper surface height of the first type 11 electrical component 10 is higher than the upper surface height of the second type 12 electrical component 10. Since the first type 11 electrical component 10 and the second type 12 electrical component 10 are plugged in together, if the second type 12 electrical component 10, which is shorter, is press-fitted first, the upper end of the first force transmission rod 30 and the upper end of the second force transmission rod 40 must be as close to the lower end of the pressure rod 20 as possible to ensure the uniformity of force transmission, which will cause the first force transmission rod 30 and the second force transmission rod 40 to be tilted. However, the specific height of the first type 11 electrical component 10 cannot be determined during pre-plugging. Therefore, when the second type 12 electrical component 10 is press-fitted first, the first force transmission rod 30 and the second force transmission rod 40 will easily collide with the second type 12 electrical component 10. Therefore, in this embodiment, the electrical components 10 of the first type 11 with a higher height are first press-fitted, so that the height of the electrical components 10 of the first type 11 is relatively uniform and accurate after being pressed into place; the shapes of the first force transmission rods 30 and the second force transmission rods 40 are designed accordingly, and when the electrical components 10 of the second type 12 are press-fitted, the first force transmission rods 30 and the second force transmission rods 40 will not collide with the electrical components 10 of the first type 11, thereby avoiding damage to the electrical components 10 of the first type 11.

[0062] Furthermore, the volume of the electrical component 10 of the first type 11 is larger than the volume of the electrical component 10 of the second type 12. Therefore, the electrical component 10 of the first type 11 with a larger volume is pressed into place first, and then the electrical component 10 of the second type 12 is pressed into place, thereby avoiding interference between the first force transmission rod 30 and the second force transmission rod 40 and the electrical component 10 of the first type 11.

[0063] Furthermore, the electrical components 10 of the first type 11 are relays, while the electrical components 10 of the second type 12 are fuses. Therefore, the larger and taller relay components must be press-fitted first, followed by the smaller and shorter fuse components. This prevents interference between the first and second dowel rods 30 and 40 and the relay components. This ensures that both the relay and fuse components are properly installed in the fuse box 60, ultimately ensuring the accuracy and reliability of the overall assembly of the electrical components 10 in the fuse box 60.

[0064] Furthermore, the diameter of the first dowel rod 30 corresponding to the first type 11 electrical component 10 is larger than the diameter of the first dowel rod 30 corresponding to the second type 12 electrical component 10. Because the first type 11 electrical component 10 is larger in size and requires greater press-fitting pressure, the larger diameter first dowel rod 30 is used to press-fit the relay component, thereby ensuring a secure installation. Furthermore, the larger diameter first dowel rod 30 can withstand greater pressure and is less likely to deform, thereby ensuring stable force transmission and providing more reliable pressure transmission for the first type 11 electrical component 10, ensuring its secure installation.

[0065] The diameter of the second dowel rod 40 corresponding to the first type 11 electrical component 10 is larger than the diameter of the second dowel rod 40 corresponding to the second type 12 electrical component 10. The use of the larger diameter second dowel rod 40 to press-fit the first type 11 electrical component 10 ensures a secure installation. The larger diameter second dowel rod 40 can withstand greater pressure and is less likely to deform, thereby ensuring stable force transmission and providing more reliable pressure transmission to the first type 11 electrical component 10, ensuring its secure installation.

[0066] Furthermore, the number of first dowel rods 30 in each first pressure zone corresponding to the first type 11 electrical component 10 is smaller than the number of first dowel rods 30 in each first pressure zone corresponding to the second type 12 electrical component 10. The smaller number of first dowel rods 30 corresponding to the first type 11 electrical component 10 not only meets the installation pressure requirements of the first type 11 electrical component 10, but also avoids structural complexity and increased costs caused by an excessive number of first dowel rods 30.

[0067] The number of second dowel rods 40 in each second pressure zone corresponding to the first type 11 electrical component 10 is smaller than the number of second dowel rods 40 in each second pressure zone corresponding to the second type 12 electrical component 10. The smaller number of second dowel rods 40 corresponding to the first type 11 electrical component 10 not only meets the installation pressure requirements of the first type 11 electrical component 10, but also avoids the structural complexity and increased cost caused by an excessive number of second dowel rods 40.

[0068] Example 2:

[0069] In this embodiment, a fuse box 60 electrical component 10 pressing device is provided for use in the fuse box 60 electrical component 10 assembly method in the first embodiment, such as Figure 2 、 Figure 3 As shown, the pressing device for the electrical component 10 of the fuse box 60 includes a pressing rod 20 , a plurality of first force transmission rods 30 , a plurality of second force transmission rods 40 , and a plurality of contour plates 50 .

[0070] The pressure rod 20 is arranged vertically, so as to facilitate applying pressure to the electrical component 10 in the vertical direction, thereby ensuring the accuracy and stability of the pressure transmission direction.

[0071] The top ends of the first dowel rods 30 are detachably connected to the bottom ends of the pressure rods 20. The detachable connection between the top ends of the first dowel rods 30 and the pressure rods 20 makes installation, maintenance, or replacement of the dowel rods more convenient. The number and specifications of the first dowel rods 30 can be flexibly adjusted according to different press-fit requirements, thereby improving the versatility and applicability of the device.

[0072] The top ends of the plurality of second force transmission rods 40 are detachably connected to the bottom ends of the pressure rods 20. The detachable connection between the top ends of the second force transmission rods 40 and the pressure rod 20 facilitates adjustment and maintenance of the second force transmission rods 40. The number and specifications of the second force transmission rods 40 can be flexibly adjusted to the characteristics of different pressure areas to ensure effective pressure transmission.

[0073] The profiling plates 50 are adapted to the shape of the distribution areas of the electrical components 10. The bottom ends of the first and second dowel rods 30, 40 are detachably connected to the multiple profiling plates 50. Each first pressure area corresponds to at least one first dowel rod 30, and each second pressure area corresponds to multiple second dowel rods 40. The profiling plates 50 are adapted to the shape of the distribution areas of the electrical components 10, allowing them to better fit the electrical components 10 and evenly distribute pressure to each component. The bottom ends of the first and second dowel rods 30, 40 are detachably connected to the profiling plates 50, facilitating installation and removal of the profiling plates 50 to accommodate different distribution areas. Furthermore, the first and second dowel rods 30, 40 are arranged corresponding to the pressure areas, ensuring that the electrical components 10 in each pressure area receive the appropriate pressure. This structural arrangement allows for uniform and precise application of pressure to the electrical components 10, thereby avoiding problems with loose insertion due to uneven pressure and ultimately ensuring the press-fit quality of the electrical components 10 in the fuse box 60.
