Description

Technical Field

[0001] The utility model relates to the technical field of chip-type ceramic capacitors, and more particularly to a chip-type ceramic capacitor with energy-saving and consumption-reducing terminal use. Background Art

[0002] Ceramic capacitors are actually a type of capacitor that uses ceramic as an electrical medium. A layer of silver is sprayed on both the front and back of the ceramic. The ceramic capacitor is then fired at a low temperature. The silver layer on the ceramic capacitor will become a thin silver film. Ceramic capacitors are very important electronic components and are widely used in various circuits, playing a key role. The following are some of the main uses of ceramic capacitors: coupling, decoupling, power reduction, etc.

[0003] For example, the patent document with the announcement number CN219759389U discloses a chip-type ceramic capacitor, including a shell, a limiting groove is opened on one side of the shell, a pin is arranged inside the shell, a limiting cover is installed on the top of the shell, and a gasket is arranged inside the shell; a chip-type ceramic capacitor, through the arrangement of the gasket, rotor, groove, and ceramic, during the use of the capacitor, conduction is achieved by welding between the pin and the gasket and the circuit board, and the rotor is rotated through the groove, so that the contact end of the bottom of the rotor rotates left and right along the outside of the ceramic, thereby approaching and moving away from the pin, so that the capacity is reduced and increased, and then the capacity of the capacitor is adjusted, thereby improving the working efficiency of the capacitor.

[0004] Existing chip ceramic capacitors use a rotor to change the distance between the rotor and the pin to adjust the size of the capacitance, but the pin and the ceramic still use a Z-structure and a rectangular block connection structure, resulting in a small contact welding area between the rectangular pin extension and the ceramic at the connection between the pin and the ceramic, making the connection loose and easy to detach.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a chip-type ceramic capacitor with energy saving and consumption reduction in terminal use. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a chip-type ceramic capacitor that is energy-saving and consumption-reducing in terminal use.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a terminal-use energy-saving and consumption-reducing chip ceramic capacitor, comprising: a shell and a base, the base being fixedly connected to the outer wall of the shell, the shell being provided with a firm structure, the upper end of the shell being provided with a disassembly structure, the firm structure comprising a ceramic chip, the ceramic chip being arranged inside the shell, pins being welded on the ceramic chip, the pins being arranged in a Z shape, the pins being fixedly connected inside the shell, and the pins being arranged in a C-shaped structure with the welding part of the ceramic chip.

[0008] Preferably, a cutout is provided on the pin.

[0009] Preferably, a support plate is fixedly connected to the outer wall of the base, and the upper end of the support plate is welded to the turning point of the Z-shaped structure of the pin.

[0010] Preferably, the disassembly and assembly structure includes a rotor, which is arranged inside the shell and is located at the upper end of the ceramic chip. A mounting groove is provided inside the shell, an upper cover is installed inside the mounting groove, and a groove is provided on the rotor.

[0011] Preferably, the outer wall of the upper cover is fixedly connected with a mounting seat, a mounting bolt is installed inside the mounting seat, and the mounting bolt is installed in a fixing groove, and the fixing groove is opened inside the shell.

[0012] Preferably, the upper cover is arranged in an annular shape, the size of the ring opened inside the upper cover is smaller than the diameter of the rotor, and the rotor is fitted with the inner wall of the bottom end of the upper cover.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In the present invention, the welding portion between the pin and the ceramic chip is changed from the original rectangular structure to a C-shaped structure. When soldering with solder, the welding can be carried out along the periphery of the C-shaped structure, thereby increasing the welding area and making the connection between the pin and the ceramic chip stable. A notch is provided on the pin, so that when welding the two sides of the pin to the ceramic chip, they no longer need to be completely close to the edge of the edge, thereby increasing the welding length again, indirectly increasing the welding area, and allowing the welding position to be close to the center of the pin, making the welding tighter. This enables the terminal to use energy-saving and consumption-reducing chip ceramic capacitors, thereby improving the connection tightness between the pin and the ceramic chip, avoiding the problem of small and weak welding area between the pin and the ceramic chip and falling off, thereby improving the practicality and firmness of the device.

[0015] 2. In the utility model, by rotating the rotor, the distance between it and the pins welded on the ceramic chip is changed, thereby conveniently changing the capacitance size and facilitating the adjustment of the capacitance. The size of the circular ring opened inside the upper cover is smaller than the diameter of the rotor, so that the rotor cannot escape from the opening of the upper cover, and the rotor fits against the inner wall of the bottom end of the upper cover, which can limit the position of the rotor inside the shell and make its rotation more stable. The upper end of the shell is assembled and connected with the upper cover, which is convenient for opening, repairing and replacing the internal components of the shell. The upper cover is installed on the upper end of the shell using a mounting seat and mounting bolts, and can be conveniently disassembled and assembled, so that the chip ceramic capacitor used in the terminal can be easily disassembled and assembled, and its internal components can be easily repaired and replaced, thereby improving the practicality and convenience of the device.
