Description

Technical Field

[0001] This application relates to the field of array-type capacitor fixing technology, specifically an array-type capacitor fixing mechanism. Background Technology

[0002] Arrayed capacitors typically refer to multiple capacitors arranged in a certain way (such as linear arrangement, matrix arrangement, etc.) into a module or unit. In the process of arranging the capacitors, copper busbars are usually soldered to the capacitors to connect the multiple groups of capacitors to each other.

[0003] In existing capacitor arrangement processes, a fixing mechanism is typically used to limit and hold the copper busbars and the arranged capacitors in place. This fixing mechanism usually consists of an end plate, a pressure plate, and positioning pins (e.g., ...). Figure 1 As shown in the figure, the pressure plate presses the positioning capacitor and, together with the positioning pin, limits the position of the copper busbar. However, during the positioning process of the copper busbar, the connecting holes on the copper busbar have different diameters to adapt to different application requirements. Therefore, when limiting the connecting holes with different diameters on the copper busbar, it is necessary to replace the positioning pin and the end plate, which increases the workload of the staff and makes this positioning method inconvenient. Therefore, it is necessary to provide an array-type capacitor fixing mechanism to solve the above problems.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] like Figure 1 As shown, this application provides an array-type capacitor fixing mechanism, including a base 1 and side lifting platforms 11 installed on both sides of the base 1. The base 1 has an opening for supporting the capacitor, and the side lifting platforms 11 have a pressure plate 13 for holding the capacitor. A positioning pin 14 is provided between the pressure plate 13 and the side lifting platforms 11 to position the pressure plate 13.

[0022] A spring pin 2 for pressing and holding the limiting pressure plate 13 is provided on the side of the side lifting platform 11, in conjunction with the reference. Figure 2 The enlarged view on the right shows that the spring pin 2 includes a main shaft 21, which is composed of a threaded section and a hexagonal section. A nut 24 is threaded onto the threaded section of the main shaft 21. The nut 24 is used to limit the main shaft 21 to be fixed on the base 1.

[0023] A sliding shaft 22 is slidably installed in the threaded section of the main shaft 21. A side groove 211 is opened on the side of the hexagonal section of the main shaft 21, and a pressure rod 221 for abutting against the pressure plate 13 is provided at the top of the sliding shaft 22. The pressure rod 221 extends out of the side groove 211, and a spring 23 is connected between the sliding shaft 22 and the top of the inner cavity of the main shaft 21. When the sliding shaft 22 moves under the action of external force, the sliding shaft 22 moves towards the top of the main shaft 21 and squeezes the spring 23. When the external force on the sliding shaft 22 disappears, under the action of the elastic force of the spring 23, the sliding shaft 22 moves back into the main shaft 21 and resets, so that the pressure rod 221 returns to the side groove 211 of the main shaft 21, and the pressure rod 221 presses and limits the pressure plate 13.

[0024] like Figures 1-2As shown, an end plate 12 for supporting the copper busbar is fixed at the end of the base 1. A countersunk hole 121 is provided on the end plate 12. A locking mechanism 3 for positioning and fixing the copper busbar is installed in the countersunk hole 121. The locking mechanism 3 includes an outer cylinder, which consists of two sets of arc shells 31 and a rubber ring 34 wrapped around the two sets of arc shells 31. The rubber ring 34 is used to fix the two sets of arc shells 31. The outer cylinder is installed at the upper end of the countersunk hole 121, and the arc shell 31 is a semi-circular arc structure and is made of elastic metal.

[0025] The top of the arc shell 31 is provided with a diagonal grooved limiting head 311, which is used to hook and limit the copper busbar. The limiting head 311 extends out of the countersunk hole 121. An inclined surface 312 is provided on the inner side of the top of the arc shell 31. The two sets of inclined surfaces 312 cooperate to form a V-shaped groove structure. At the same time, a wedge-shaped pressure head 32 is provided between the inclined surfaces 312 of the two sets of arc shells 31. An adjusting rod 33 is passed through the two sets of arc shells 31. The adjusting rod 33 passes through the wedge-shaped pressure head 32 and is fixedly connected to the wedge-shaped pressure head 32. The adjusting rod 33 extends out of the two sets of arc shells 31 and is threadedly connected to the lower section of the countersunk hole 121.

[0026] When the copper busbar is fitted onto the outer cylinder, first rotate the adjusting rod 33 so that the adjusting rod 33 moves deeper into the countersunk hole 121 and drives the wedge-shaped pressure head 32 to move into the V-groove of the outer shaft to squeeze the two sets of arc shells 31, thereby making the limiting heads 311 of the two sets of arc shells 31 move away from each other, and with the diagonal pattern of the limiting heads 311, the copper busbar is limited and fixed.

[0027] In summary, with the cooperation of the wedge-shaped pressure head 32 and the inclined surface 312 of the two sets of arc shells 31, and with the threaded cooperation of the adjusting rod 33 and the lower section of the countersunk hole 121, the wedge-shaped pressure head 32 is suitable for pressing the two sets of arc shells 31 so that the limiting heads 311 of the two sets of arc shells 31 are far apart from each other, thereby achieving the effect of limiting the copper busbars of different diameter connecting holes.

[0028] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations are possible for those skilled in the art. Any improvements and modifications made within the spirit and principles of this application, without departing from its principles, should also be considered within the scope of protection of this application.
