Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of electrical plug - in structures, and particularly relates to a quick - insertion structure for LTD module capacitors. Background Art
[0002] The capacitors of existing LTD modules are mainly installed and fixed to conductors through screws. Although the connection stability can be effectively guaranteed to ensure the passage of high - voltage current, when the capacitor is damaged, a relatively large number of screws need to be disassembled and assembled to replace the capacitor, resulting in an extended replacement time and a low replacement efficiency. Currently, there are also plug - in structures used to connect capacitors. Such plug - in structures usually have elastic conductive sheets arranged on one side or opposite inner walls inside the female end to press the male end. However, the installation of such conductive sheets in this plug - in structure is rather difficult, and once the conductive sheet is damaged, it is not only difficult to detect but also difficult to replace. Summary of the Utility Model
[0003] To solve the deficiencies of the prior art, the utility model provides a quick - insertion structure for LTD module capacitors, which is convenient for quickly replacing capacitors, and it is easier to detect the damage of the conductive spring sheets and easier to replace the damaged conductive spring sheets.
[0004] To achieve the purpose of the utility model, the following scheme is proposed:
[0005] A quick - insertion structure for LTD module capacitors includes: a female - end connector and a male - end plug.
[0006] The female - end connector includes two parallel - arranged connecting plates with a fixed interval therebetween.
[0007] The male - end plug includes a plug - in plate whose width is smaller than the width of the connecting plate and whose thickness is smaller than the interval between the two connecting plates. The rear end of the plug - in plate is used to connect the capacitor. On the top and bottom surfaces of the front end of the plug - in plate, a plurality of spaced - apart conductive spring sheets are arranged along the width direction. The two ends of the conductive spring sheet are arranged in the front - and - rear direction of the plug - in plate, and both ends of the conductive spring sheet are in contact with the plug - in plate. The middle parts of the conductive spring sheets respectively have arc - convex structures towards the outside of the plug - in plate, and the distance between the middle parts of the conductive spring sheets on both sides of the plug - in plate is greater than the interval between the two connecting plates.
[0008] When connecting, the front end of the plug - in plate is inserted into the interval between the two connecting plates, the outer wall of the middle part of the conductive spring sheet abuts against the inner wall of the connecting plate, and the conductive spring sheet is in a compressed state.
[0009] The beneficial effects of the present utility model are as follows: When replacing or overhauling, the capacitor can be removed only by plugging and unplugging, and the disassembly and assembly of the capacitor are more convenient and fast. Moreover, the conductive spring pieces for conduction are arranged on the plugging board of the male end plug, which not only facilitates the quick discovery of the damage of the conductive spring pieces, but also is convenient for disassembly and assembly.

[0015] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the embodiments described herein are only part of the embodiments of the present utility model, not all of them.
[0016] As Figures 1 to 3 shown, a fast - plug structure for LTD module capacitors includes: a female end joint 1 and a male end plug 2.
[0017] Specifically, the female end joint 1 includes two connecting plates 11 arranged in parallel, with a predetermined interval between the two connecting plates 11. The connecting plates 11 are made of stainless steel to ensure sufficient strength and extend the service life.
[0018] Specifically, the male end plug 2 includes a plugging board 21, whose width is smaller than the width of the connecting plate 11, and the thickness is smaller than the interval between the two connecting plates 11. The rear end of the plugging board 21 is used to connect the capacitor. On the top and bottom surfaces of the front end of the plugging board 21, a plurality of spaced - apart conductive spring pieces 22 are arranged along the width direction. The two ends of the conductive spring piece 22 are arranged in the front - rear direction of the plugging board 21, and both ends of the conductive spring piece 22 are in contact with the plugging board 21. The middle part of the conductive spring piece 22 has an arc - convex structure towards the outside of the plugging board 21, and the distance between the middle parts of the conductive spring pieces 22 on both sides of the plugging board 21 is greater than the interval between the two connecting plates 11. The plugging board 21 and the conductive spring pieces 22 are made of copper.
[0019] When connecting, the front end of the plug-in board 21 is inserted into the gap between the two connecting boards 11. The outer wall of the middle part of the conductive spring piece 22 abuts against the inner wall of the connecting board 11, and the conductive spring piece 22 is in a compressed state, so as to ensure the contact stability between the male end plug 2 and the female end joint 1.
[0020] For such a plug-in structure, when replacing or overhauling, the capacitor can be removed only by plugging and unplugging, and the disassembly and assembly of the capacitor are more convenient and fast. And the conductive spring piece 22 for conduction is arranged on the plug-in board 21 of the male end plug 2, which not only facilitates the quick discovery of the damage of the conductive spring piece 22, but also is convenient for disassembly and assembly. The middle part of the conductive spring piece 22 is in an arc convex structure, and both ends of the conductive spring piece 22 are in contact with the plug-in board 21, so the front ends of the conductive spring pieces 22 on both sides of the plug-in board 21 present an acute angle structure, which is more convenient for inserting between the two connecting boards 11.
[0021] Preferably, the front ends of multiple conductive spring pieces 22 on the same side of the plug-in board 21 are connected into an integral structure for quick replacement. As another preferred structure, the conductive spring piece 22 is a single-piece structure, so that it can be replaced separately after a single piece is damaged, reducing the maintenance cost.
[0022] Preferably, as Figure 3 shown, two rows of conductive spring pieces 22 are provided on both the top surface and the bottom surface of the plug-in board 21 to enhance the connection effect.
[0023] Further preferably, as Figure 1 、 Figure 2 shown, the front end of the conductive spring piece 22 is connected to the plug-in board 21 by screws, and the rear end of the conductive spring piece 22 is in sliding contact with the surface of the plug-in board 21. When the conductive spring piece 22 is pressed, the effect of elastic deformation of the size can be achieved by the sliding of its rear end, so as to avoid permanent deformation of the conductive spring piece 22.
[0024] The above are only the preferred embodiments of the present invention, and do not represent that they are the only ones or limit the present invention. Those skilled in the art should understand that without departing from the scope of the present invention, various changes or equivalent replacements made to the present invention all belong to the scope of protection of the present invention.
