[0043] A plurality of electrical elements 10 need to be installed on the fuse box 60. Since the installation of a plurality of electrical elements 10 requires a long time to repeat the plugging action, the operator is prone to physical fatigue, and the concentration and operation accuracy will also decrease. In this case, the electrical element 10 is frequently plugged in, that is, the electrical element 10 is connected to the fuse box 60. In this way, the quality of the electrical element 10 installed on the fuse box 60 and the overall work efficiency cannot be guaranteed.

[0044] Embodiment One:

[0045] In this embodiment, in order to solve the above problems, the embodiment provides a fuse box 60 electrical element 10 assembly method, as shown in the figure, the fuse box 60 electrical element 10 assembly method includes steps S10~S70, the following can be described in detail steps S10~S70: Figure 1 ​

[0046] Step S10, the plurality of electrical elements 10 are pre-inserted on the fuse box 60 under the first pressure, so that the electrical elements 10 and the fuse box 60 complete the preliminary positioning, thereby laying the foundation for subsequent operations. It should be understood that under the action of the first pressure, the electrical elements 10 are usually not directly pressed to the bottom.

[0047] Step S20, the distribution area of the plurality of electrical elements 10 after pre-insertion is obtained, and the distribution of the electrical elements 10 on the fuse box 60 is determined, so as to facilitate subsequent reasonable division and processing of the distribution area.

[0048] Step S30, the distribution area is divided into a plurality of first pressure areas and a plurality of second pressure areas. Through such a region division mode, the distribution of the electrical elements 10 can be accurately classified, and the basis for adopting different compression strategies for different regions in the subsequent process is provided, so that the entire compression process is more targeted and reasonable. The first pressure area includes a set of positions of the plurality of electrical elements 10 arranged in a matrix along the first direction and the second direction. The first direction and the second direction are perpendicular, the first direction is the left-right direction shown in Figure 3 , and the second direction is the up-down direction shown in Figure 3 . The second pressure area includes a set of positions of the plurality of electrical elements 10 arranged along the first direction or the second direction. The plurality of first pressure areas and the plurality of second pressure areas have intervals between each other. It should be understood that in the case that the total number of electrical elements 10 in the first pressure area and the second pressure area remains the same, the electrical elements 10 in the first pressure area are arranged along two directions and are more concentrated, and the electrical elements 10 in the second pressure area are arranged along one direction and are more dispersed.

[0049] Step S40, based on the distribution area division is completed, install the pressing device. Through the pressing device, it can ensure the effective transmission and distribution of force in the subsequent pressing process. The pressing device 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 profiling plates 50. The top end of the plurality of first force transmission rods 30 and the plurality of second force transmission rods 40 is connected to the bottom end of the pressing rod 20, and the spacing between the top end of the first force transmission rod 30 and the bottom end of the pressing rod 20 is equal to the spacing between the top end of the second force transmission rod 40 and the bottom end of the pressing rod 20. The top end of the pressing rod 20 is provided with a driver, and the driver drives the horizontal movement and lifting of the pressing rod 20, 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 driving source such as a cylinder or a lead 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, and the shape of part of the profiling plate 50 corresponds to the shape of the first pressure area, and part corresponds to the shape of the second pressure area, so that the electrical elements 10 in different areas can be pressed down. At the same time, the profiling plate 50 can increase the contact area with the upper surface of the electrical element 10, so that when the electrical element 10 is assembled, the stress can be more uniform. Since the electrical elements 10 in the first pressure area are distributed in a matrix form, the stress area of the profiling plate 50 along the first direction and the second direction is relatively uniform, so each first pressure area corresponds to at least one first force transmission rod 30. The second pressure area is distributed along the first direction or the second direction, so that the electrical elements 10 in the second pressure area present a long strip shape, so each second pressure area corresponds to a plurality of second force transmission rods 40, so that the stress area of the profiling plate 50 in the second pressure area along the first direction and the second direction is relatively uniform. In this way, according to the distribution area of different shapes, a corresponding number of first force transmission rods 30 and second force transmission rods 40 are set, which not only can make the electrical elements 10 stress uniform, but also can reduce the number of first force transmission rods 30 and second force transmission rods 40 as much as possible, thereby reducing the cost.

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

[0051] Step S60, drive the pressing device to move to the 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. In this way, it can be ensured that the force can act on the electrical elements 10 in each area during the pressing process of the profiling plate 50, and the accuracy and effectiveness of the pressing can be ensured.

[0052] At step S70, based on the fact that the pressing device is located at the initial position, the pressing rod 20 is driven to move downward until the downward pressure of the pressing rod 20 reaches a second pressure, and the pressing is completed. The second pressure is averagely distributed to the downward pressure on each of the electrical elements 10, and the downward pressure is greater than the first pressure. The pre-plugging and plugging of the electrical elements 10 to the bottom are compared, and the latter requires a greater pressure, so that the downward pressure of the second pressure, which is averagely distributed to each of the electrical elements 10, is set to be greater than the first pressure, so as to ensure that the multiple electrical elements 10 can be accurately pressed into place when they are synchronously pressed to the bottom. Since the stress point of the downward pressure is located at the geometric center of the distribution area, the stress of each of the electrical elements 10 is uniform, avoiding the situation that the plugging is not tight, and ensuring the product quality.

[0053] Further, when the number of the electrical elements 10 in the first pressure area and the second pressure area is the same, since the first pressure area includes multiple electrical elements 10 arranged in a matrix along the first direction and the second direction, the distribution is relatively concentrated, and therefore the number of the first force transmission rods 30 should not be too large to simplify the structure. However, since the required pressure is large, the strength of the first force transmission rod 30 needs to be increased. Therefore, one first force transmission rod 30 corresponds to each first pressure area, and the diameter of the first force transmission rod 30 is greater than that of the second force transmission rod 40. The first force transmission rod 30 with a larger diameter can withstand greater pressure and reduce deformation, ensuring the stability and reliability of force transmission. The second pressure area corresponds to a profiled plate 50 in the shape of a long strip, and therefore multiple second force transmission rods 40 need to be arranged to ensure that the electrical elements 10 in the second pressure area are uniformly stressed. The stress of the multiple second force transmission rods 40 is relatively dispersed, and therefore the diameter of the first force transmission rod 30 is greater than that of the second force transmission rod 40. Through such a structural arrangement, the electrical elements 10 in the first pressure area and the second pressure area can all obtain sufficient and stable pressure, so as to realize uniform stress and ensure product quality.

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

[0055] The distance between the bottom ends of two adjacent second force transmission rods 40 in each second pressure area is a second distance. The first distance is less than the second distance. Since the electrical elements 10 in the first pressure area are arranged in a matrix, the number is relatively large and dense, and the smaller first distance can make the multiple first force transmission rods 30 fit more closely, providing more uniform and sufficient pressure for the electrical elements 10; while the electrical elements 10 in the second pressure area are arranged in a single direction, and the larger second distance is sufficient to ensure effective pressure transmission. By setting different distances in this way, the electrical elements 10 in the first pressure area and the second pressure area can all obtain appropriate and uniform pressure, thereby ensuring the pressing quality of the electrical elements 10.

[0056] Further, since the first distance is smaller than the second distance, the electrical elements 10 of the first pressure area are distributed relatively concentrated, while the plurality of first force transmission rods 30 are arranged, the diameter of the first force transmission rod 30 can be smaller than the diameter of the second force transmission rod 40, so that the first force transmission rod 30 is more flexible in the limited space of the profiling plate 50, thereby ensuring the uniform stress of the electrical elements 10 of the first pressure area and the pressing quality of the electrical elements 10. Since the electrical elements 10 of the second pressure area are distributed relatively dispersed, in the case that the number of electrical elements 10 distributed to each force transmission rod is equal, in order to apply the downward pressure to each dispersed electrical element 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 as an ellipse, and the long axis of the ellipse is parallel to the distribution direction of the electrical elements 10 in the second pressure area.

[0057] In some other embodiments, the fuse box 60 electrical element 10 assembly method further comprises steps S80 and S90, which will be described in detail below:

[0058] The electrical elements 10 have a first type 11 and a second type 12. The electrical elements 10 of the first type 11 and the second type 12 are synchronously executed step S10 to pre-insert all electrical elements 10 in the fuse box 60 according to the preset distribution position. Thus, the assembly efficiency of the fuse box 60 can be improved.

[0059] Step S80, based on the electrical elements 10 of the first type 11, steps S20-S70 are executed until the electrical elements 10 of the first type 11 are completed.

[0060] Step S90, after the electrical elements 10 of the first type 11 are completed, based on the electrical elements 10 of the second type 12, steps S20-S70 are executed until the electrical elements 10 of the second type 12 are completed; after the first type 11 element is completed, the corresponding operation is performed on the second type 12 element, so that the assembly process of the two types of elements is orderly carried out, avoiding mutual interference, and improving the assembly efficiency.

[0061] The upper surface height of the electrical element 10 of the first type 11 is higher than the upper surface height of the electrical element 10 of the second type 12 in the state of the press-fitting of the electrical element 10 of the first type 11 and the electrical element 10 of the second type 12. Since the electrical element 10 of the first type 11 and the electrical element 10 of the second type 12 are inserted together, if the electrical element 10 of the second type 12 with a lower height 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 need to be close to the lower end of the press rod 20 as much as possible, so as 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 inclined. The pre-insertion cannot determine the specific height of the electrical element 10 of the first type 11, so that when the electrical element 10 of the second type 12 is press-fitted first, the first force transmission rod 30 and the second force transmission rod 40 will easily collide with the electrical element 10 of the second type 12. Therefore, the electrical element 10 of the first type 11 with a higher height is press-fitted first in the embodiment, so that the height of the electrical element 10 of the first type 11 is uniform and accurate after being press-fitted; the shapes of the first force transmission rod 30 and the second force transmission rod 40 are designed correspondingly, and when the electrical element 10 of the second type 12 is press-fitted, the first force transmission rod 30 and the second force transmission rod 40 will not collide with the electrical element 10 of the first type 11, thereby avoiding damage to the electrical element 10 of the first type 11.

[0062] Further, the volume of the electrical element 10 of the first type 11 is larger than the volume of the electrical element 10 of the second type 12, so that the electrical element 10 of the first type 11 with a larger volume is press-fitted first, and then the electrical element 10 of the second type 12 is press-fitted, thereby avoiding interference between the first force transmission rod 30 and the second force transmission rod 40 and the electrical element 10 of the first type 11.

[0063] Further, the electrical element 10 of the first type 11 is a relay element, and the electrical element 10 of the second type 12 is a fuse element. Therefore, the relay element with a larger volume and a higher height needs to be press-fitted, and then the fuse element with a smaller volume and a lower height is press-fitted, thereby avoiding interference between the first force transmission rod 30 and the second force transmission rod 40 and the relay element. It is ensured that the relay element and the fuse element can be correctly installed into the fuse box 60, and finally the accuracy and reliability of the overall assembly of the electrical element 10 of the fuse box 60 are ensured.

[0064] Further, the diameter of the first force bar 30 corresponding to the electrical element 10 of the first type 11 is greater than the diameter of the first force bar 30 corresponding to the electrical element 10 of the second type 12. Since the electrical element 10 of the first type 11 has a larger volume and requires a larger pressing force, the first force bar 30 with a larger diameter is used to press the relay element, thereby ensuring stable installation. At the same time, the first force bar 30 with a larger diameter can withstand greater pressure and is less likely to deform, thereby ensuring the stability of force transmission and providing more reliable pressure transmission for the electrical element 10 of the first type 11, ensuring firm installation.

[0065] The diameter of the second force bar 40 corresponding to the electrical element 10 of the first type 11 is greater than the diameter of the second force bar 40 corresponding to the electrical element 10 of the second type 12. The second force bar 40 with a larger diameter is used to press the electrical element 10 of the first type 11, thereby ensuring stable installation. At the same time, the second force bar 40 with a larger diameter can withstand greater pressure and is less likely to deform, thereby ensuring the stability of force transmission and providing more reliable pressure transmission for the electrical element 10 of the first type 11, ensuring firm installation.

[0066] Further, the number of first force bars 30 in each first pressure area corresponding to the electrical element 10 of the first type 11 is less than the number of first force bars 30 in each first pressure area corresponding to the electrical element 10 of the second type 12. The electrical element 10 of the first type 11 corresponds to a smaller number of first force bars 30, which can meet the installation pressure requirements of the electrical element 10 of the first type 11 and avoid excessive first force bars 30 causing structural complexity and cost increase.

[0067] The number of second force bars 40 in each second pressure area corresponding to the electrical element 10 of the first type 11 is less than the number of second force bars 40 in each second pressure area corresponding to the electrical element 10 of the second type 12. The electrical element 10 of the first type 11 corresponds to a smaller number of second force bars 40, which can meet the installation pressure requirements of the electrical element 10 of the first type 11 and avoid excessive second force bars 40 causing structural complexity and cost increase.

[0068] Embodiment Two:

[0069] In this embodiment, the fuse box 60 electrical element 10 pressing device is applied to the fuse box 60 electrical element 10 assembly method in Embodiment One, as shown in Figure 2 , Figure 3 The fuse box 60 electrical element 10 pressing device includes a pressing rod 20, a plurality of first force bars 30, a plurality of second force bars 40, and a plurality of profiling plates 50.

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

[0071] The top ends of the first force transmission rods 30 are detachably connected to the bottom end of the pressure rod 20. The detachable connection of the top ends of the first force transmission rods 30 to the pressure rod 20 makes it more convenient to install, maintain or replace the force transmission rods, and the number and specifications of the first force transmission rods 30 can be flexibly adjusted according to different pressing requirements, improving the versatility and applicability of the device.

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

[0073] The profiled plates 50 are adapted to the shape of the distribution area of the electrical element 10. The bottom ends of the first force transmission rods 30 and the second force transmission rods 40 are detachably connected to the plurality of profiled plates 50. Each first pressure area corresponds to at least one first force transmission rod 30, and each second pressure area corresponds to a plurality of second force transmission rods 40. The profiled plates 50 are adapted to the shape of the distribution area of the electrical element 10, which can better fit the electrical element 10 and make the pressure evenly distributed to each element; the detachable connection of the bottom ends of the first force transmission rods 30 and the second force transmission rods 40 to the profiled plates 50 facilitates the installation and removal of the profiled plates 50 to adapt to different distribution areas. At the same time, the first force transmission rods 30 and the second force transmission rods 40 are arranged corresponding to the pressure areas, which can ensure that each electrical element 10 in the pressure area can obtain appropriate pressure. Through such a structural arrangement, uniform and accurate pressure can be applied to the electrical element 10, thereby avoiding the problem of not being tightly inserted due to uneven pressure, and ultimately ensuring the pressing quality of the electrical element 10 of the fuse box 60.

[0074] Those skilled in the art can understand that the above embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and details without departing from the scope of the present disclosure.
