[0002] Leaded capacitors are capacitor devices used in aluminum electrolysis equipment, but existing leaded capacitors still have shortcomings, specifically: the outer wall of existing capacitors does not have a protective device, making the capacitors easily damaged by external impacts.

[0003] Therefore, a leaded aluminum electrolytic capacitor is needed to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a leaded aluminum electrolytic capacitor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A leaded aluminum electrolytic capacitor includes a capacitor body, and a protective mechanism is provided on the outer wall of the capacitor body.

[0007] The protection mechanism includes a protective shell slidably connected to the outer wall of the capacitor body. A connecting strip is slidably connected to the outer wall of the protective shell. A connecting block is fixedly connected to the outer wall of the protective shell near the connecting strip. A positioning pin is slidably connected inside the connecting block and inside the connecting strip. A sliding rod is fixedly connected to the outer wall of the positioning pin and inside the connecting strip. An adjusting ring is fixedly connected to the outer wall of the sliding rod above the connecting strip. A compression spring is fixedly connected to the bottom end of the sliding rod and inside the connecting strip. A thermal pad is fixedly connected to the inner wall of the protective shell. A heat dissipation groove is formed on the outer wall of the protective shell.

[0008] As a preferred embodiment of this utility model, the capacitor body is a leaded capacitor.

[0009] As a preferred embodiment of this utility model, the protective shell, connecting block, and positioning pin are all made of aluminum alloy, and the connection between the compression spring and the connecting strip, as well as the connection between the connecting strip and the capacitor body, are all fixed connections.

[0010] As a preferred embodiment of this utility model, the protective shell and connecting strip are provided in two sets, and the positioning pin, sliding rod and connecting strip are all connected by sliding connection.

[0011] As a preferred embodiment of this utility model, both the sliding rod and the adjusting ring are made of ABS plastic, and the positioning pin has an L-shaped structure design.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, a leaded aluminum electrolytic capacitor is designed. The protective mechanism in the device protects the capacitor body. Two sets of protective shells are fixed to the outer wall of the capacitor body by connecting strips. When an external object hits the capacitor body, the protective shell will protect the capacitor body. At the same time, the heat-conducting pad on the inner wall of the protective shell can transfer the heat generated by the operation of the capacitor body to the protective shell in time, and dissipate it into the air through the heat dissipation groove on the outer wall of the protective shell. This solves the problem that the existing capacitors do not have a protective device on the outer wall, which makes the capacitor easy to be damaged by external impact. Attached Figure Description
