Description

Technical Field

[0001] The utility model relates to the technical field of wiring devices, and particularly relates to a wiring device for an electrolytic capacitor. Background Art

[0002] An electrolytic capacitor is a component widely used in electronic circuits, which has the advantages of large capacitance, small volume, wide frequency response range, good capacitance stability, etc.

[0003] In the prior art, through retrieval, it is found that a Chinese patent discloses a wiring device for an anti-breakdown aluminum electrolytic capacitor, and its application number is 201721621882.9. The above patent mainly includes: a quick connector, pins, a cover plate, an aluminum shell, an insulating outer film, a wire, a core package, a fixing agent, and an explosion-proof valve. The quick connector is installed above the pins and is connected movably. The pins are installed above the cover plate and are in interference fit. The cover plate is installed above the aluminum shell and is connected by glue. The insulating outer film is installed around the aluminum shell and is in interference fit. The wire is installed above the core package and is fixed by welding. The fixing agent is installed around the core package and is connected in a surrounding manner. Although the above utility model realizes that the improved wiring device for the anti-breakdown aluminum electrolytic capacitor can protect the pins inside the connector, the wiring is fast, the pins can be replaced conveniently and are not easy to fall off. However, in the above device, the quick connector is connected to the pins by the clamping of a movable elastic piece. The design of the movable elastic piece relies on its elasticity to clamp the pins. Due to factors such as the contact area between the movable elastic piece and the pins and the elasticity of the movable elastic piece, the friction force and clamping force between the elastic piece and the pins may not reach an ideal balance, which may cause the elastic piece to fail to stably maintain the clamping state of the pins when the capacitor is vibrated or the temperature changes; and the movable elastic piece may show fatigue or aging phenomena after long-term use, resulting in a decrease in the clamping force and affecting the stability of the wiring. Therefore, those skilled in the art provide a wiring device for an electrolytic capacitor to solve the problems raised in the above background art. Summary of the Utility Model

The function of the drawings is to supplement the description in the text part of the specification, enabling people to intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but it cannot be understood as a limitation on the protection scope of the present utility model.

[0023] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , in an embodiment of a wiring device for an electrolytic capacitor of the present utility model, it includes a capacitor body 1, a concave part 2 provided on the outer side of the capacitor body 1 and near the top, and two pins 3 provided on the top of the capacitor body 1. A wiring board 4 is attached to the top of the capacitor body 1. Two conductive columns 6 inserted into the corresponding pins 3 are fixedly connected inside the wiring board 4. A positioning plate 5 is fixedly connected to the outside of the wiring board 4. The bottom of the positioning plate 5 extends to the concave part 2 and is provided with a chute 9. A plurality of positioning components cooperatively connected with the concave part 2 are symmetrically arranged at equal intervals inside the chute 9; the positioning components include a spring 8 fixedly connected inside the chute 9 and a positioning block 7 slidably connected inside the chute 9 and fixedly connected to one end of the spring 8. The positioning block 7 extends into the concave part 2 and is arranged in an arc structure cooperatively connected with the concave part 2;

[0024] Specifically, when the wiring board 4 covers the top of the capacitor body 1, the positioning plate 5 is sleeved outside the capacitor body 1. The wiring board 4 covering the top of the capacitor body 1 enables the conductive column 6 to be inserted into the pin 3, so that the electrical connection operation between the conductive column 6 and the capacitor body 1 can be completed, facilitating the quick connection of the wire through the conductive column 6 and the capacitor body 1. When the positioning plate 5 is sleeved outside the capacitor body 1, the arc-shaped positioning block 7 can move into the inner part of the sliding groove 9 by fitting with the outside of the capacitor body 1. The positioning block 7 moving to one side of the sliding groove 9 moves towards one side of the capacitor body 1 under the action of the spring 8, and can better fit with the inner surface of the recessed part 2. The connection work between the positioning plate 5 and the capacitor body 1 can be completed through the cooperation and connection of the positioning block 7 and the recessed part 2, which is beneficial to ensuring the stable connection between the conductive column 6 and the pin 3. The overall structure is simple, the wiring is convenient, and the conductive column 6 is well fixed when connected to the capacitor body 1, which can effectively prevent the loosening or falling off of the conductive column 6 and the pin 3, improving the stability and reliability of use.

[0025] Refer to Figure 1 , Figure 2 and Figure 3 , a protective cover 10 is movably connected to the top of the wiring board 4. The protective cover 10 is screwed to the wiring board 4. The screwed protective cover 10 is convenient to open and close and has a stable connection. And a wire passing hole 11 is opened at the center of the protective cover 10. A wire protection coil 12 is embedded in the inside of the wire passing hole 11. The wire protection coil 12 is made of rubber material. Specifically, after passing the wire through the wire protection coil 12, it is connected to the connection piece 13. Under the action of the wire protection coil 12, the wire passing hole 11 can be protected. After the protective cover 10 is screwed to the outside of the wiring board 4, the connection between the wire and the conductive column 6 can be better protected through the protective cover 10.

[0026] Refer to Figure 3 , connection pieces 13 are fixedly connected to the tops of both conductive columns 6, and threaded holes 14 are provided inside the connection pieces 13. The metal connection pieces 13 can fit with the connected wires, and the threaded holes 14 can be used in cooperation with bolts to facilitate the connection work between the wires and the connection pieces 13, and the connection is firm.

[0027] The conductive column 6 and the pin 3 are connected by interference fit. The conductive column 6 and the pin 3 connected by interference fit insertion increase the connection stability and are beneficial to ensuring the electrical connection operation between the conductive column 6 and the pin 3.

[0028] Working principle: When the wiring board 4 covers the top of the capacitor body 1, the positioning plate 5 is sleeved outside the capacitor body 1. The wiring board 4 covering the top of the capacitor body 1 enables the conductive column 6 to be inserted into the pin 3, so that the electrical connection operation between the conductive column 6 and the capacitor body 1 can be completed, facilitating the quick connection of the wire to the capacitor body 1 through the conductive column 6. When the positioning plate 5 is sleeved outside the capacitor body 1, the arc-shaped positioning block 7 can move into the inner side of the chute 9 by fitting with the outside of the capacitor body 1. The positioning block 7 moving to one side of the chute 9 moves towards one side of the capacitor body 1 under the action of the spring 8, and can better fit with the inner surface of the recess 2. The connection work between the positioning plate 5 and the capacitor body 1 can be completed through the cooperation and connection between the positioning block 7 and the recess 2, thus facilitating the guarantee of the stable connection between the conductive column 6 and the pin 3. The overall structure is simple, the wiring is convenient, and the conductive column 6 is well fixed when connected to the capacitor body 1, which can effectively prevent the loosening or falling off of the conductive column 6 and the pin 3, and improve the stability and reliability of use.
