Description

Technical Field

[0001] The utility model relates to the technical field of capacitors, in particular to a ceramic vacuum capacitor with high sealing performance. Background Art

[0002] Capacitors are a commonly used energy storage component. Some electrolytes used in supercapacitors have low viscosity and strong permeability, so they have high requirements for the sealing of the external packaging.

[0003] A high-sealing capacitor disclosed in announcement number CN217768126U, although, when in use, the first metal gland and the second metal gland can be compounded together, after the first metal gland and the second metal gland are compounded together, the cathode pin and the anode pin will pass through the first notch and the second notch respectively, so that the pins are connected to the inner core of the capacitor, and the material in the capacitor needs to break through the insulating glue between the first metal gland and the second metal gland if it wants to contact the outside world, thereby improving the sealing characteristics of the capacitor.

[0004] However, this highly sealed ceramic vacuum capacitor has the following disadvantages:

[0005] (1) When some capacitors are used for too long, it is difficult to position and reinforce the sealing ring, which causes the sealing ring to shift easily, resulting in poor sealing after the capacitor is used for a long time;

[0006] (2) The installation steps during the use of the capacitor are too complicated, resulting in poor flexibility in capacitor installation. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a highly practical, highly sealed ceramic vacuum capacitor that can be operated with simple operation and a relatively simple structure. It solves the problem mentioned in the above background technology that when some capacitors are used for too long, it is difficult to position and reinforce the sealing ring, which causes the sealing ring to easily shift, resulting in the capacitor being used for a long time and resulting in poor sealing. The installation steps during the use of the capacitor are too cumbersome, resulting in poor flexibility in capacitor installation.

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a highly sealed ceramic vacuum capacitor, comprising a capacitor body, a sealing ring is clamped on the top surface of the capacitor body, a metal cover for increasing stability is attached to the surface of the sealing ring, protective plates are fixedly installed on both sides of the capacitor body, a bottom cover is threadedly connected to the bottom of the protective plate, and a suction cup is provided at the bottom of the bottom cover.

[0009] Optionally, a connecting ring is fixedly connected to the edge of the suction cup, and the top surface of the connecting ring is provided with screws having equidistant threads in a circular array.

[0010] Optionally, a module is disposed inside the suction cup, and an inner portion for connecting to a capacitor body is embedded on a top surface of the module.

[0011] Optionally, a waterproof membrane for increasing waterproofness is attached to the outer surface of the protective plate, and a soft pad for increasing protectiveness is attached to the inner wall of the protective plate.

[0012] Optionally, the top surface of the metal cover is provided with a connector for connecting to the outside, and a sealing head is clamped at the bottom of the connector.

[0013] Optionally, the outer surface of the bottom cover is coated with an anti-skid film coating for increasing anti-skid properties, and the outer surface of the capacitor body is affixed with an anti-rust coating.

[0014] The utility model provides a ceramic vacuum capacitor with high sealing performance, which has the following beneficial effects:

[0015] 1. The highly sealed ceramic vacuum capacitor has a metal cover, a sealing ring and a capacitor body. When the staff uses the capacitor body for too long and the sealing ring is squeezed for a long time, the metal cover can position the sealing ring to avoid position displacement and accidental deformation of the sealing ring.

[0016] 2. The highly sealed ceramic vacuum capacitor has a bottom cover, a protective plate and a suction cup. When the staff installs the capacitor body, the capacitor body can be installed at a designated working position, and then the suction cup can be pressed to quickly adsorb the capacitor body to the designated working position, thereby facilitating the staff to quickly install the capacitor body.
