Description

Technical Field

[0001] The utility model relates to the technical field of ceramic capacitors, in particular to an environmentally friendly high-voltage ceramic capacitor. Background Art

[0002] Capacitors, usually referred to as capacitance for their ability to hold charge, are one of the electronic components used extensively in electronic equipment. They are widely used in circuits for DC isolation, AC passing, coupling, bypassing, filtering, tuning circuits, energy conversion, and control. Environmentally friendly high-voltage ceramic capacitors are capacitors with ceramic as the dielectric.

[0003] For example, an environmentally friendly high-voltage ceramic capacitor with the authorization announcement number "CN208580668U" has solved the problem that the existing environmentally friendly high-voltage ceramic capacitors are corroded by moisture and rusted, or the adhesion of impurities affects their subsequent use. The above-mentioned fireproof layer set outside the thickened outer sealing layer can improve the fire and high-temperature resistance of the ceramic capacitor body, and the fireproof effect is good. The resistant layer set outside the fireproof layer has good wear resistance, which can improve the wear resistance of the outer skin of the ceramic capacitor body and has good protective performance. Considering the existing environmentally friendly high-voltage ceramic capacitors, the pins at the lower end of the ceramic capacitor body need to be manually pried to change their position, and the force of manual prying is difficult to control, which makes the connection between the pins and the ceramic capacitor body loose, resulting in a shortened service life. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the force of manual bending of existing environmentally friendly high-voltage ceramic capacitors is difficult to control, which causes the connection between the pins and the ceramic capacitor body to loosen, resulting in a shortened service life.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an environmentally friendly high-voltage ceramic capacitor, comprising a ceramic capacitor body and pins, the lower end of the ceramic capacitor body being fixedly connected to the pins, the outer wall of the ceramic capacitor body being fixedly connected to the wear-resistant layer, and the outer wall of the ceramic capacitor body being connected to a protective mechanism.

[0006] Preferably, the protective mechanism includes a first protective shell, the inner wall of the first protective shell is tightly pressed against the wear-resistant layer, the inner wall of the first protective shell is threadedly connected to the fixing screw, the end of the fixing screw is threadedly connected to the second protective shell, and the inner wall of the first protective shell is fixedly connected to the limit plate.

[0007] Preferably, the outer wall of the limiting plate is tightly pressed against the pin, and the outer wall of the pin is provided with an adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes a shell, the inner wall of the shell is tightly against the pin, the outer wall of the shell is fixedly connected to the gradient bar, the inner wall of the gradient bar is slidably connected to the slider, and the outer wall of the slider is fixedly connected to the support rod.

[0009] Preferably, the outer wall of the wear-resistant layer is fixedly connected to the model plate.

[0010] Preferably, the outer wall of the outer shell is movably connected to the first protective shell.

[0011] The utility model proposes an environmentally friendly high-voltage ceramic capacitor, which has the following beneficial effects: the slider at the end of the support rod slides on the inner wall of the slope block, so that the slope block drives the change of the angle of the pin inside the shell, and the force of changing the angle of the lower end of the pin is easier, and the limiting plate on the first protective shell clamps the pin, so the position of the connection between the pin and the ceramic capacitor body will not be loosened due to the change of the pin angle, thereby improving the service life.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Example 1:

[0021] See also Figure 1-6 : In this embodiment, an environmentally friendly high-voltage ceramic capacitor includes a ceramic capacitor body 1 and a pin 2, the lower end of the ceramic capacitor body 1 is fixedly connected to the pin 2, the outer wall of the ceramic capacitor body 1 is fixedly connected to the wear-resistant layer 4, and the outer wall of the ceramic capacitor body 1 is connected to a protective mechanism 5.

[0022] The protective mechanism 5 includes a first protective shell 501. The inner walls of the first protective shell 501 and the second protective shell 503 are pressed against the outer wall of the ceramic capacitor body 1, so that the limit plate 504 on the first protective shell 501 limits the position of the upper end of the pin 2, thereby achieving the effect of protecting the pin 2 from the ceramic capacitor body 1. The inner wall of the first protective shell 501 is pressed against the wear-resistant layer 4. The inner wall of the first protective shell 501 is threadedly connected to the fixing screw 502. The end of the fixing screw 502 is threadedly connected to the second protective shell 503. The inner wall of the first protective shell 501 is fixedly connected to the limit plate 504.

[0023] The outer wall of the limit plate 504 is tightly against the pin 2. The outer wall of the pin 2 is provided with an adjustment mechanism 6. By changing the distance between the slope bar 602 and the support rod 604, the slope bar 602 drives the angle adjustment effect of the pin 2 inside the housing 601. The adjustment mechanism 6 includes a housing 601. The inner wall of the housing 601 is tightly against the pin 2. The outer wall of the housing 601 is fixedly connected to the slope bar 602. The inner wall of the slope bar 602 is slidably connected to the slider 603. The outer wall of the slider 603 is fixedly connected to the support rod 604.

[0024] The slider 603 at the end of the support rod 604 slides on the inner wall of the slope block 602, so that the slope block bar 602 drives the change of the angle of the pin 2 inside the shell 601, making it easier for the lower end of the pin 2 to change the angle, and the limit plate 504 on the first protective shell 501 clamps the pin 2, so that the position between the pin 2 and the ceramic capacitor body 1 will not be loosened due to the change of the angle of the pin 2, thereby improving the service life.

[0025] Working principle:

[0026] Protection stage

[0027] By fitting the inner walls of the first protective shell 501 and the second protective shell 503 to the wear-resistant layer 4 of the outer wall of the ceramic capacitor body 1 and tightening the first protective shell 501 and the second protective shell 503 by screwing the fixing screws 502, the inner walls of the first protective shell 501 and the second protective shell 503 are pressed against the outer wall of the ceramic capacitor body 1, and the limiting plate 504 on the first protective shell 501 clamps the pin 2. When the pin 2 is subjected to external tension, the pin 2 and the ceramic capacitor body 1 will not loosen, ensuring a firm connection between the end of the pin 2 and the ceramic capacitor body 1, thereby reducing damage to the ceramic capacitor body 1 during use. When the ceramic capacitor body 1 is electrically connected to the pin 2, when the DC rated voltage capacitor is used in an AC circuit or a ripple current circuit, the Vp-p value of the applied voltage or the V0-p value including the DC bias voltage is maintained within the rated voltage range, thereby extending the life of the capacitor, reducing resource waste, and achieving the purpose of environmental protection.

[0028] Adjustment phase

[0029] By manually pushing the support rod 604 up and down, the slider 603 at the end of the support rod 604 slides on the inner wall of the slope block 602. At the same time, due to the change in the distance between the slope bar 602 and the support rod 604, the slope block bar 602 drives the change in the angle of the pin 2 inside the shell 601, making it more convenient to connect the end of the pin 2 with the external installation position.

[0030] Example 2:

[0031] See also Figure 1-6 : In this embodiment, the outer wall of the wear-resistant layer 4 is fixedly connected to the model plate 3, and the outer wall of the outer shell 601 is movably connected to the first protective shell 501.

[0032] Auxiliary protection stage

[0033] The wear-resistant layer 4 is made of polyvinyl chloride, which has good wear resistance and can improve the wear resistance of the outer skin of the ceramic capacitor body 1, with good protective performance. The outside of the wear-resistant layer 4 has a model plate 3 to increase the model information and provide a warning effect for use.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
