It is a general-purpose electrolytic capacitor made of aluminum material with good electrical properties, wide application range and high reliability.

[0003] However, it still has the following disadvantages in actual use:

[0004] A capacitor with high reliability is disclosed with a publication number of CN218160027U. The core comprises a core body, a positive electrode lead and a negative electrode lead. The core body is formed by stacking and winding a first electrolytic paper, a positive electrode aluminum foil, a second electrolytic paper and a negative electrode aluminum foil in sequence.

A plurality of positive electrode aluminum foil sheets electrically connected to the positive electrode aluminum foil are arranged at equal intervals at the top of the positive electrode aluminum foil, and all the positive electrode aluminum foil sheets are electrically connected to the positive electrode lead. A plurality of negative electrode aluminum foil sheets electrically connected to the negative electrode aluminum foil are arranged at equal intervals at the bottom of the negative electrode aluminum foil, and all the negative electrode aluminum foil sheets are electrically connected to the negative electrode lead.

[0005] However, when the above device is connected to the circuit, the pins of the capacitor need to be cleaned first to avoid impurities generated during contact and affecting the contact quality of the capacitor. Generally, the cleaning is done manually, and improper operation can easily damage the pins, affecting normal use, and the cleaning efficiency is low. Utility Model Content

[0006] The utility model aims to provide an overvoltage resistant aluminum electrolytic capacitor to solve the problem raised in the above-mentioned background technology. However, when the above-mentioned device is connected to the circuit, the pins of the capacitor need to be cleaned first to avoid impurities generated during contact, which affects the contact quality of the capacitor. Generally, the cleaning is performed manually, and improper operation can easily cause damage to the pins, affecting normal use, and the cleaning efficiency is low.

[0007] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0008] The utility model is an overvoltage-resistant aluminum electrolytic capacitor, comprising:

[0009] Subject institution;

[0010] The protection mechanism comprises a telescopic sleeve movably sleeved on the circumferential outer wall of the lead wire of the main body mechanism, the upper end of the telescopic sleeve is fixedly connected to a connecting frame, the inner cavity of the connecting frame is hollow, the hollow inner cavity of the connecting frame is symmetrically fixedly connected to a connecting spring, the outer wall of the connecting spring away from one end of the connecting frame is fixedly connected to a sleeve frame, and the outer wall of the sleeve frame is rotatably connected to a rotating plate.

[0011] Furthermore, it also includes a pressure-resistant mechanism, which includes a pressure-resistant frame fixedly connected to the circumferential outer wall of the main body mechanism;

[0012] Furthermore, a connecting sleeve is threadedly connected to the top of the compression frame, and one end of the telescopic sleeve is fixedly connected to the outer wall of the connecting sleeve;

[0013] Furthermore, it also includes a telescopic mechanism, the telescopic mechanism includes a synchronous frame fixedly sleeved on the outer walls of the two connecting frames, and the outer walls of the synchronous frame are fixedly connected with a connecting rod;

[0014] Furthermore, the outer wall of one end of the connecting rod away from the synchronous frame is fixedly connected with a pressing rod, the outer wall of the connecting sleeve is fixedly connected with a fixing frame, and the pressing rod passes through one end of the fixing frame and is movably connected with a sliding frame;

[0015] Furthermore, the sliding frame is slidably connected to the inner wall of the fixed frame, a sliding groove is provided on the outer wall of the sliding frame, a bayonet is provided on the top of the sliding groove, a limit spring is movably connected to the bottom of the sliding frame, one end of the limit spring is fixedly connected to the inner wall of the fixed frame, a rotating rod is slidably connected to the inner cavity of the sliding groove, and the other end of the rotating rod is rotatably connected to the outer wall of the fixed frame;

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] 1. In the utility model, the telescopic sleeve is extended and retracted to protect the pins of the capacitor. When the capacitor does not need to be connected to the circuit, the telescopic sleeve is stretched to drive the connecting frame to move, and the connecting frame drives the sleeve frame to move. When the telescopic sleeve is stretched to the longest, the connecting frame drives the sleeve frame to move to the highest point of the pin, and the connecting spring rebounds to drive the rotating plate to rotate along the sleeve frame. After the rotating plates on both sides are rotated by the connecting spring rebound, the two rotating plates are made to fit each other by their own weight, and the top of the telescopic sleeve is closed to provide airtight protection for the pins. When connection is required, the cleaning of the pins is reduced, the cleaning efficiency is improved, and the normal use of the pins is guaranteed.

[0018] 2. Based on beneficial effect 1, when the pressing rod is manually pressed, the pressing rod drives the sliding frame to slide on the fixed frame. When the sliding frame squeezes the limit spring, the rotating rod slides in the sliding groove and slides to the bayonet to limit the rotating rod, so that the pressing rod is at the lowest height. The pressing rod drives the connecting rod to press down, and the connecting rod drives the synchronous frame to press down, thereby driving the telescopic sleeve to press down. The telescopic sleeve is pressed down to make the rotating plate contact the pin to rotate and open the telescopic sleeve, so that the pin leaks out for connection. When the pressing rod is pressed again, the sliding frame is disengaged from the bayonet, and the pressing rod is released. The limit spring rebounds to make the sliding frame return to its position, thereby making the pressing rod return to its position, so that the telescopic sleeve is at its longest, and the pin is protected. The telescopic sleeve can be easily stretched or shortened, thereby protecting the pin or leaking out.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
