Description

Technical Field

[0001] The utility model relates to the technical field of electrical components, and specifically relates to a ceramic capacitor. Background Technique

[0002] Ceramic capacitors are widely used in various electronic devices, such as mobile phones, tablet computers, televisions, computers, etc. They are used in circuits such as power filtering, coupling, and insulation of windings to provide stable power supply and electrical signal transmission.

[0003] For example, the existing patent (publication number: CN217061780U) discloses a ceramic capacitor. In the utility model, plug-in male heads or plug-in female heads are arranged at both ends of the ceramic capacitor body for plug-in connection with an external circuit. When the ceramic capacitor body is provided with a plug-in male head, the plug-in part of the plug-in male head is matched and plugged with an external female head part to achieve reliable connection of the circuit; when the ceramic capacitor body is provided with a plug-in female head, the plug-in hole of the plug-in female head is matched and plugged with an external male head to achieve reliable connection of the circuit.

[0004] However, there are still some disadvantages in the actual use of the above-designed electric hoist with a fall prevention function: when the external circuit is short-circuited for some reasons, the short-circuit current will increase rapidly. If there are no appropriate protection measures (such as fuses, circuit breakers, etc.) at this time, the large current may pass through the parallel ceramic capacitors. Since the ceramic capacitor has a certain internal resistance, heat will be generated when the large current passes through, resulting in an increase in the internal temperature of the capacitor. The high temperature may also cause physical and chemical changes in the internal materials of the capacitor, further affecting its performance.

[0005] Therefore, we designed a ceramic capacitor to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide a ceramic capacitor to solve the problems raised in the above background technique.

[0007] To solve the above technical problems, a ceramic capacitor provided by the utility model includes a body. The body includes a first capacitor. A first plug connector and a second plug connector are respectively arranged at both ends of the first capacitor. An insurance component is arranged at the bottom of the body. The insurance component includes a connector electrically connected to the bottom surface of the first capacitor. A fuse is electrically connected to the bottom surface of the connector. A fixing member is arranged on the fuse.

[0008] Further, the fixing member includes a module clip clamped on the bottom surface of the fuse. The connector is fixedly connected to the top of the module clip. A fixing seat is fixedly connected to the bottom of the module clip. The fixing seat is arranged on the bottom surface of the first capacitor.

[0009] Further, the fixing member further includes support seats symmetrically arranged on both sides of the module clamp. The support seats are fixedly connected to the top of the fixed seat. Each support seat is fixedly connected with a socket frame, and on one side opposite to the top of each socket frame is a connecting plate.

[0010] Further, each connecting plate is fixed on the first capacitor. A socket hole is formed in the connecting plate. A socket rod is threadedly connected between the socket hole and the socket frame. A fastening bolt is threadedly connected to the top of the socket rod, and the bottom surface of the fastening bolt abuts against the socket hole.

[0011] Further, a second capacitor is fixedly connected to the top of the first capacitor. A plurality of first electrical leads are electrically connected to both sides of the second capacitor, and electrical lead plates are arranged on both sides of the second capacitor.

[0012] Further, the other ends of two of the first electrical leads that are close to each other are electrically connected to the electrical lead plates. A second electrical lead is fixedly connected to the bottom of each electrical lead plate. The other ends of the two second electrical leads are respectively electrically connected to a first plug and a second plug.

[0013] Further, the fixing member further includes a mounting groove formed at the bottom of the fixed seat. The mounting groove is used for fixing socket screws, and the screws are used to fix the insurance component in the corresponding position.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the circuit plugged into the first plug and the second plug is short-circuited, a large amount of heat will be generated, causing it to accumulate a large amount of heat in the first capacitor and the fuse. The melt in the fuse will quickly melt, thereby cutting off the circuit. The advantage of this is that the fuse can quickly melt when the current exceeds the rated value, effectively preventing the first capacitor from being short-circuited and overloaded due to external factors, protecting the first capacitor from damage, reducing property losses, and being safer and more reliable during use;

[0015] When the circuit is short-circuited, the second capacitor electrically connected to the first plug and the second plug through the second electrical lead and the electrical lead plate will share a part of the heat for the first capacitor, preventing damage to the inside of the first capacitor by heat before the melt in the fuse melts. The advantage of this is that the second capacitor can absorb some of the excess energy, preventing all of this energy from impacting the first capacitor and causing damage to it, improving the safety of the circuit.
